    A Pygopus 2-Histone Interaction Is Critical for Cancer Cell Dedifferentiation and Progression in Malignant Breast Cancer2020In: Cancer Research, ISSN 0008-5472, E-ISSN 1538-7445, Vol. 80, no 17, p. 3631-3648Article in journal (Refereed)
    Abstract [en]

    Pygopus 2 (Pygo2) is a coactivator of Wnt/b-catenin signaling that can bind bi- or trimethylated lysine 4 of histone-3 (H3K4me(2/3)) and participate in chromatin reading and writing. It remains unknown whether the Pygo2-H3K4me(2/3) association has a functional relevance in breast cancer progression in vivo. To investigate the functional relevance of histone-binding activity of Pygo2 in malignant progression of breast cancer, we generated a knock-in mouse model where binding of Pygo2 to H3K4me(2/3) was rendered ineffective. Loss of Pygo2-histone interaction resulted in smaller, differentiated, and less metastatic tumors, due, in part, to decreased canonical Wnt/b-catenin signaling. RNA- and ATAC-sequencing analyses of tumor-derived cell lines revealed downregulation of TGF beta signaling and upregulation of differentiation pathways such as PDGFR signaling. Increased differentiation correlated with a luminal cell fate that could be reversed by inhibition of PDGFR activity. Mechanistically, the Pygo2-histone interaction potentiated Wnt/beta-catenin signaling, in part, by repressing the expression of Wnt signaling antagonists. Furthermore, Pygo2 and beta-catenin regulated the expression of miR-29 family members, which, in turn, repressed PDGFR expression to promote dedifferentiation of wild-type Pygo2 mammary epithelial tumor cells. Collectively, these results demonstrate that the histone binding function of Pygo2 is important for driving dedifferentiation and malignancy of breast tumors, and loss of this binding activates various differentiation pathways that attenuate primary tumor growth and metastasis formation. Interfering with the Pygo2-H3K4me(2/3) interaction may therefore serve as an attractive therapeutic target for metastatic breast cancer. Significance: Pygo2 represents a potential therapeutic target in metastatic breast cancer, as its histone-binding capability promotes beta-catenin-mediated Wnt signaling and transcriptional control in breast cancer cell dedifferentiation, EMT, and metastasis.

    Hybrid Materials for Wearable Electronics and Electrochemical Systems2022Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Flexible electronic systems such as wearable devices, sensors and electronic skin require power sources and sensing units that are mechanically robust, operational at low bending radius, and environmentally friendly. Recently, there has been an enormous interest in active materials such as thin film semiconductors, conductive polymers, and ion-electron conductors. These materials can be deposited with both printing and microfabrication techniques onto the flexible substrates such as plastics and paper. In addition, paper-based composites with nanofibrillated cellulose are favorable due to their mechanical strength, porosity, and solution-processability. Printing of such systems enables mass-production of large area electrochemical devices i.e., batteries, supercapacitors and fuel cells. Moreover, designing ultrathin devices for such concepts are promising for implantable and skin-like conformable electronics.

    The aim of this thesis is the development of flexible electronic devices where, both organic and inorganic materials are explored, and examples of smart packaging and wearable electronics are demonstrated. Within the thesis, two different fabrication approaches are presented to achieve flexible electronics: (1) fabrication of porous paper electrodes for printable, wearable supercapacitor applications, where our efforts towards sustainable solutions for energy storage and (2) development of ultraflexible devices for electronic skin and implantable electronics to attain miniaturized, ultrathin device concepts. Overall, high performance electronic devices and demonstrators shown here have a significant impact on portable hybrid systems and flexible electronics applications.

    Abstract [en]

    Energy storage technology incorporating conducting polymers as the active component in electrode structures, in part based on natural materials, is a promising strategy toward a sustainable future. Electronic and ionic charge transport in poly(3,4-ethylenedioxythiophene) (PEDOT) provides fundamentals for energy storage, governed by volumetric PEDOT:counterion double layers. Despite extensive experimental investigations, a solid understanding of the capacitance in PEDOT-based nanocomposites remains unsatisfactory. Here, we report on the charge storage mechanism in PEDOT composited with cellulose nanofibrils (termed as "power paper") from three different perspectives: experimental measurements, density functional theory atomistic simulations, and device-scale simulations based on the NernstPlanck-Poisson equations. The capacitance of the power paper was investigated by varying the film thickness, charging currents, and electrolyte ion concentrations. We show that the volumetric capacitance of the power paper originates from electrostatic molecular double layers defined at atomistic scales, formed between holes, localized in the PEDOT backbone, and their counterions. Experimental galvanostatic cycling characteristics of the power paper is well reproduced within the electrostatic Nernst-PlanckPoisson model. The difference between the specific capacitance and the intrinsic volumetric capacitance is also outlined. Substantial oxygen reduction reactions were identified and recorded in situ in the vicinity of the power paper surface at negative potentials. Purging of dissolved oxygen from the electrolyte leads to the elimination of currents originating from the oxygen reduction reactions and allows us to obtain well-defined electrostatic-capacitive behavior (box-shaped cyclic voltammetry and triangular galvanostatic charge-discharge characteristics) at a large operational potential window from -0.6 V to +0.6 V. The obtained results reveal that the fundamental charge storage is a result of electrostatic Stern double layers in both oxidized and reduced electrodes, and the developed theoretical approaches provide a predictive tool to optimize performance and device design for energy storage devices based on highperformance conducting polymer electrodes.

    Abstract [en]

    The increasing demands to further electrify and digitalize our society set demands for a green electrical energy storage technology that can be scaled between very small, and heavily distributed electrical energy sources, to very large volumes. Such technology must be compatible with fast-throughput, large-volume and low-cost fabrication processes, such as using printing and coating techniques. Here, we demonstrate a sequential production protocol to fabricate supercapacitors including electrodes based on cellulose nanofibrils (CNF) and the conducting polymer PEDOT:PSS. Thin and lightweight paper electrodes, carbon adhesion layers and the gel electrolyte are fabricated using spray coating, screen printing, and bar coating, respectively. These all solid-state supercapacitors are flexible, mechanically robust and exhibit a low equivalent series resistance (0.22 ohm), thus resulting in a high power density (similar to 10(4)W/kg) energy technology. The supercapacitors are combined and connected to a power management circuit to demonstrate a smart packaging application. This work shows that operational and embedded supercapacitors can be manufactured in a manner to allow for the integration with, for instance smart packaging solutions, thus enabling powered, active internet-of-things (IoT) devices in a highly distributed application.

    Abstract [en]

    Ultrathin devices are rapidly developing for skin-compatible medical applications and wearable electronics. Powering skin-interfaced electronics requires thin and lightweight energy storage devices, where solution-processing enables scalable fabrication. To attain such devices, a sequential deposition is employed to achieve all spray-coated symmetric microsupercapacitors (mu SCs) on ultrathin parylene C substrates, where both electrode and gel electrolyte are based on the cheap and abundant biopolymer, cellulose. The optimized spraying procedure allows an overall device thickness of approximate to 11 mu m to be obtained with a 40% active material volume fraction and a resulting volumetric capacitance of 7 F cm(-3). Long-term operation capability (90% of capacitance retention after 10(4) cycles) and mechanical robustness are achieved (1000 cycles, capacitance retention of 98%) under extreme bending (rolling) conditions. Finite element analysis is utilized to simulate stresses and strains in real-sized mu SCs under different bending conditions. Moreover, an organic electrochromic display is printed and powered with two serially connected mu-SCs as an example of a wearable, skin-integrated, fully organic electronic application.

    Scalable Paper Supercapacitors for Printed Wearable Electronics2022In: ACS Applied Materials and Interfaces, ISSN 1944-8244, E-ISSN 1944-8252, Vol. 14, no 50, p. 55850-55863Article in journal (Refereed)
    Abstract [en]

    Printed paper-based electronics offers solutions to rising energy concerns by supplying flexible, environmentally friendly, low-cost infrastructure for portable and wearable electronics. Herein, we demonstrate a scalable spray-coating approach to fabricate tailored paper poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS)/cellulose nanofibril (CNF) electrodes for all-printed supercapacitors. Layer-by-layer spray deposition was used to achieve high-quality electrodes with optimized electrode thickness. The morphology of these electrodes was analyzed using advanced X-ray scattering methods, revealing that spray-coated electrodes have smaller agglomerations, resulting in a homogeneous film, ultimately suggesting a better electrode manufacturing method than drop-casting. The printed paper-based supercapacitors exhibit an areal capacitance of 9.1 mF/cm(2), which provides enough energy to power electrochromic indicators. The measured equivalent series resistance (ESR) is as low as 0.3 Omega, due to improved contact and homogeneous electrodes. In addition, a demonstrator in the form of a self-powered wearable wristband is shown, where a large-area (90 cm(2)) supercapacitor is integrated with a flexible solar cell and charged by ambient indoor light. This demonstration shows the tremendous potential for sequential coating/printing methods in the scaling up of printed wearables and self-sustaining systems.

    Ultrathin polymer electrochemical microcapacitors for on-chip and flexible electronics2023In: Organic electronics, ISSN 1566-1199, E-ISSN 1878-5530, Vol. 115, article id 106751Article in journal (Refereed)
    Abstract [en]

    Advances in organic electronics necessitates, ultrathin and miniaturized implantable energy storage modules. Here, an approach for the fabrication of on-chip, ultraflexible electrochemical capacitors is demonstrated. Two different electroactive conjugated polymers are utilized in a fabrication route that allows the patterning of finger electrodes for an ultraflexible energy storage technology. A strategy is demonstrated to realize supercapacitors with a total device thickness of 4 mu m, including substrate, polymer electrode, and electrolyte. Interdigitated 20 -finger electrodes from either Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) or poly-thiophene functionalized with tetraethylene glycol side chains P(g42T-T), with 50 mu m or 90 mu m electrode spacings, are fabricated using a parylene peel off method, followed by electrolyte deposition. The miniaturized devices show 0.77 mF/cm2 areal capacitance for PEDOT:PSS and 0.06 mF/cm2 for P(g42T-T). Furthermore, the devices exhibit excellent mechanical durability, showing robust operational performance at a bending radius of 6.5 mm.

    Fatty infiltration and muscle atrophy of the rotator cuff in stemless total shoulder arthroplasty: a prospective cohort study2018In: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 27, no 6, p. 976-982Article in journal (Refereed)
    Abstract [en]

    Background: The influence of preoperative rotator cuff fatty infiltration (FI) and muscle atrophy (MA) on the postoperative outcome of total shoulder arthroplasty (TSA) has only rarely been investigated and reported in the literature. We hypothesized that more FI and MA would be associated with a worse postoperative functional outcome. Methods: This prospective cohort study included 63 patients (31 female and 32 male patients; mean age, 71 years [range, 53-89 years; standard deviation, 7 years]) with primary osteoarthritis of the shoulder operated on with anatomic stemless TSA. Preoperatively and at 3 months and 1 year after the operation, the functional outcome (QuickDASH [short version of Disabilities of the Arm, Shoulder and Hand questionnaire] score) and range of motion (ROM) (goniometer) and strength (dynamometer) for abduction at the scapular plane and for external rotation were measured. The degree of preoperative FI and MA was evaluated using computed tomography scans according to the Goutallier classification and Warner classification, respectively, for the supraspinatus and infraspinatus. Results: We found clinically and statistically significant improvements in functional outcome, strength, and ROM at both 3 months and 1 year of follow-up compared with those preoperatively. The Pearson correlation coefficient (r) showed significant correlations between preoperative supraspinatus and infraspinatus FI and MA and preoperative and 1-year postoperative shoulder abduction and external rotation strength but not ROM. However, we found no influence of the rotator cuff FI and MA on the functional outcome after TSA. Conclusion: We demonstrated a significant correlation between rotator cuff FI and MA and strength but not ROM of the shoulder joint. (C) 2017 Journal of Shoulder and Elbow Surgery Board of Trustees.

    Mutational patterns and clonal evolution from diagnosis to relapse in pediatric acute lymphoblastic leukemia2021In: Scientific Reports, E-ISSN 2045-2322, Vol. 11, no 1, article id 15988Article in journal (Refereed)
    Abstract [en]

    The mechanisms driving clonal heterogeneity and evolution in relapsed pediatric acute lymphoblastic leukemia (ALL) are not fully understood. We performed whole genome sequencing of samples collected at diagnosis, relapse(s) and remission from 29 Nordic patients. Somatic point mutations and large-scale structural variants were called using individually matched remission samples as controls, and allelic expression of the mutations was assessed in ALL cells using RNA-sequencing. We observed an increased burden of somatic mutations at relapse, compared to diagnosis, and at second relapse compared to first relapse. In addition to 29 known ALL driver genes, of which nine genes carried recurrent protein-coding mutations in our sample set, we identified putative non-protein coding mutations in regulatory regions of seven additional genes that have not previously been described in ALL. Cluster analysis of hundreds of somatic mutations per sample revealed three distinct evolutionary trajectories during ALL progression from diagnosis to relapse. The evolutionary trajectories provide insight into the mutational mechanisms leading relapse in ALL and could offer biomarkers for improved risk prediction in individual patients.

    Pulsed plasma chemical synthesis of carbon-containing titanium oxide-based composite2017In: Fullerenes, nanotubes, and carbon nanostructures, ISSN 1536-383X, E-ISSN 1536-4046, Vol. 25, no 9, p. 526-530Article in journal (Refereed)
    Abstract [en]

    The carbon-containing titanium oxide-based composite was first obtained using a pulsed plasma chemical method. The composite was obtained from the following reagents: TiCl4, CH4, and O-2. The physical and chemical properties of the TixCyOz composite powders were studied (morphology, chemical, elemental and phase composition). The presence of spherical particles and the cubic and prismatic particles were typical for the synthesised carbon-containing titanium oxide-based composites. The large particles are observed (the average size exceeds 150nm) and smaller particles (the average size is 15-30nm). The presence of the dense layer of amorphous carbon (10-15nm thick) around particles is typical for the composites. The peak with a maximum of 1080cm(-1) is registered in IR absorption spectrum of the TixCyOz synthesised composite. The presence of IR radiation in this region of the spectrum is typical for the deformation of atomic oscillations in the Ti-O-C bond, which indicates that carbon and titanium in the composite are bound through oxygen. The content of the defined amount of titanium carbide has not been detected.

    On the possibility of controlling the morphology of carbon-containing titanium dioxide-based nanocomposites during pulsed plasma chemical synthesis2019In: Fullerenes, nanotubes, and carbon nanostructures, ISSN 1536-383X, E-ISSN 1536-4046, Vol. 27, no 9, p. 677-683Article in journal (Refereed)
    Abstract [en]

    Three sets of carbon-containing nanocomposites based on titanium dioxide were synthesised by changing the concentrations of the original precursors (CH4, (2)) using a pulsed plasma chemical method. The elemental and chemical analyses of the synthesised nanocomposites were performed. The morphology of the carbon-containing titanium dioxide-based nanocomposites was studied by transmission electron microscopy. To determine the crystal structures of the nanocomposites, the standard method of X-ray phase analysis was used. The band gaps for the synthesised carbon-containing titanium dioxide-based composites were calculated using the diffuse reflectance spectra in the range of 1.3-3.6eV. It was experimentally proved that the band gap for indirect transitions depended on the total carbon content in the synthesised samples and was 2.76eV for some samples.

    Synthesis of multicomponent nanocomposites containing filamentary carbon nanostructures2020In: Fullerenes, nanotubes, and carbon nanostructures, ISSN 1536-383X, E-ISSN 1536-4046, Vol. 28, no 6, p. 446-451Article in journal (Refereed)
    Abstract [en]

    In this work, the multicomponent nanocomposites containing filamentary carbon nanostructures were synthesized using materials based on iron oxides with a predominant content of the epsilon phase (epsilon-Fe2O3). These iron oxide-based materials were obtained by a direct plasma-dynamic synthesis with supersonic outflow of an iron-containing electric discharge plasma into an oxygen atmosphere. Subsequently, they were used as an initial precursor and placed in the plasma-chemical reactor, where the multicomponent C/SixOy/Fe2O3 nanostructures were synthesized under the influence of the pulsed electron beam. This method was based on the volume excitation of the reaction gas by a pulsed electron beam in such a way as to control the uniform process implementation in the entire excitation region. The morphology and phase composition of the synthesized C/SixOy/Fe2O3 nanocomposites were studied. A typical morphological feature of the C/SixOy/Fe2O3 samples was found to be the formation of filamentary nanostructures. Their diameter does not exceed 10-20 nm, while their length varies up to 1 mu m.

    Study of the Influence of Morphology, Chemical and Phase Compositions of Zinc Oxide-Containing Silicon and Titanium Oxide Nanomaterials on Cytotoxic Activity2021In: BioNanoScience, ISSN 2191-1630, E-ISSN 2191-1649, Vol. 11, no 2, p. 539-548Article in journal (Refereed)
    Abstract [en]

    The pulsed plasma-chemical method was used to obtain zinc oxide-contthe morphology and histograms of the particle aining silicon and titanium oxide nanocomposites (ZnOx-SiO2 and ZnOx-TiO2). To realize the method, a TEA-500 pulsed electron accelerator (Tomsk, Russia) was used. Zinc oxide (ZnO) nanopowder was obtained using the electrospark method. The morphology and phase composition of the synthesized nanopowders were determined using transmission electron microscopy (TEM) and X-ray diffraction (XRD) methods. The cytotoxicity of ZnO, ZnOx-SiO2, and ZnOx-TiO2 nanomaterials on HepG2 and 3T3-L1 adhesive cell lines was studied using thiazolyl blue tetrazolium bromide (MTT; Sigma). It was found that the size of the synthesized particles was in the range of 40-150 nm. The phase composition of ZnO, ZnOx-SiO2, and ZnOx-TiO2 nanomaterials was presented by several crystal structures. The dominant crystal lattice was ZnO with a hexagonal lattice for the ZnO sample, Zn (hexagonal lattice) for the ZnOx-SiO2 sample, and anatase for the ZnOx-TiO2 sample. The morphology of the ZnO, ZnOx-SiO2, and ZnOx-TiO2 nanoparticles was diverse. The cytotoxicity of ZnOx-SiO2 composite nanomaterials was much lower than that of the ZnO nanoparticles. The effect of increasing the viability of cells under the influence of low doses of ZnOx-TiO2 composite nanomaterials was revealed. These research results may present useful information for specialists involved in the development and application of functional nanocomposites.

    Molecular sampling of prostate cancer: a dilemma for predicting disease progression2010In: BMC Medical Genomics, E-ISSN 1755-8794, Vol. 3, no 8Article in journal (Refereed)
    Abstract [en]

    Background: Current prostate cancer prognostic models are based on pre-treatment prostate specific antigen (PSA) levels, biopsy Gleason score, and clinical staging but in practice are inadequate to accurately predict disease progression. Hence, we sought to develop a molecular panel for prostate cancer progression by reasoning that molecular profiles might further improve current clinical models. Methods: We analyzed a Swedish Watchful Waiting cohort with up to 30 years of clinical follow up using a novel method for gene expression profiling. This cDNA-mediated annealing, selection, ligation, and extension (DASL) method enabled the use of formalin-fixed paraffin-embedded transurethral resection of prostate (TURP) samples taken at the time of the initial diagnosis. We determined the expression profiles of 6100 genes for 281 men divided in two extreme groups: men who died of prostate cancer and men who survived more than 10 years without metastases (lethals and indolents, respectively). Several statistical and machine learning models using clinical and molecular features were evaluated for their ability to distinguish lethal from indolent cases. Results: Surprisingly, none of the predictive models using molecular profiles significantly improved over models using clinical variables only. Additional computational analysis confirmed that molecular heterogeneity within both the lethal and indolent classes is widespread in prostate cancer as compared to other types of tumors. Conclusions: The determination of the molecularly dominant tumor nodule may be limited by sampling at time of initial diagnosis, may not be present at time of initial diagnosis, or may occur as the disease progresses making the development of molecular biomarkers for prostate cancer progression challenging.

    Epitaxial growth and electrical-transport properties of Ti(7)Si(2)C(5) thin films synthesized by reactive sputter-deposition2011In: Scripta Materialia, ISSN 1359-6462, E-ISSN 1872-8456, Vol. 65, no 9, p. 811-814Article in journal (Refereed)
    Abstract [en]

    Epitaxial predominantly phase-pure Ti(7)Si(2)C(5) thin films were grown onto Al(2)O(3)(0 0 0 1) by reactive magnetron sputtering. The c-axis lattice constant is similar to 60.2 angstrom; the Ti(7)Si(2)C(5) unit cell comprises alternating Ti(3)SiC(2)-like and Ti(4)SiC(3)-like half-unit-cell stacking repeated three times. Elastic recoil detection analysis showed a few percent of nitrogen in the films from the acetylene gas used. The nitrogen-induced stabilization mechanism for Ti(7)Si(2)C(5) relative to Ti(3)SiC(2) and Ti(4)SiC(3) is discussed. Electrical-transport measurements showed metallic temperature dependence and a room-temperature resistivity of similar to 45 mu Omega cm.

    Weak electronic anisotropy in the layered nanolaminate Ti 2 GeC2008In: Solid State Communications, ISSN 0038-1098, E-ISSN 1879-2766, Vol. 146, no 11-12, p. 498-501Article in journal (Refereed)
    Abstract [en]

    We have investigated the anisotropy in electronic transport of the layered ternary Ti2GeC by comparing the results of measurements on c-axis oriented epitaxial thin-film and polycrystalline bulk samples. The electrical conductivities, Hall coefficients, and magnetoresistances were analyzed within a multi-band framework. An adequate description of the magnetotransport data on the film with the highest mobility required the use of the explicit field-dependent conductivity tensor with three conduction bands. The analysis indicated that n ˜ p, although with n ˜ 3.5 × 1027 m- 3. The ratio of the a- to c-axis conductivities is small and contrary to theoretical predictions. © 2008 Elsevier Ltd.

    Indicators of Phase Transition within the Vehicle’s Lifecycle: A Case Study of Scania2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The total lifecycle of a vehicle contains many phases, from production to sales to first customer to second customer and so on until the end of life. Each one of these phases includes different activities in different business areas and under different conditions. This means that the customers´ needs will vary depending on which lifecycle phase the vehicle is in and the offered services have to be adapted to this. Therefore it is important for truck developing companies to know when a transition, from one lifecycle phase to another has occurred.

    This study is based on a case study provided by Scania, a company that develops trucks and busses. Delimitations were that the study would focus on connected long-haulage trucks that are in Europe under their first life cycle phase, that the developed services would be described on a conceptual level and not cover any economic aspects. With this in mind, the following research questions were created:

    RQ1) What defines a transition phase?

    RQ2) How can the long-haulage trucks’ usage pattern be used to identify a transition phase?

    RQ3) Which data is needed to identify a transition phase?

    RQ4) Based on the results of RQ2 and RQ3, how could the transition alert service be designed?

    RQ5) Which applications could the transitions alert service be used for?

    The study included a literature study covering product lifecycle theory, servicification, second-hand market, big data, telematics, intelligent vehicles and statistic hypothesis testing. Further, two truck drivers were observed in order to get better understanding of the transportation business and the truck driving activities. Two qualitative interview studies were made with hauliers, service salesmen, truck salesmen and distributors from Czech Republic, Denmark, Italy, Poland, Spain and Sweden.

    The results of the empirical studies were analysed and RQ1 could be answered. Transition phase is the period between two different vehicle owners and/or two different ways of utilizing the truck. The analysis also gave a good picture of how the trucks are used during their life and in the transition phases, which gave an idea about usage patterns that could answer RQ2. The answer was formulated as something named phase-DNA, composed by six parameters that should change during a transition phase: Geography, Route, Driver, Traffic Condition, Assignments and Services.

    Through a group brainstorming with experts in connected services, ideas of which data that could be used to describe each one of the parameters in the phase-DNA were found. These were sorted and evaluated until at least one data type for each parameter was set. The specific data types were chosen because they reflected their parameter well and because they were data that were accessible in order to conduct tests and validations. The final set of data types consisted of: Route Shape, Amount of Stops, Run Time, Idle Time, Distance Driven, Coasting, Driver ID, Average Speed, Fuel Consumption and Workshop History Data. This set of data types was used for the formulation of a hypothesis, that said that after a transition phase at least some of these data types should change. This was also the point where RQ3 was answered. II

    The hypothesis was analysed using an exploratory analysis by plotting all the data types over time and observing if a change could be seen close to the change of ownership. The result showed that Amount of Stops and Driver ID were the most indicative data types, these two were further analysed with a statistical hypothesis test and a visualisation method. The results were used to develop an algorithm that is able to give an indication if a transition phase has occurred. The algorithm searches for changes in the six data types: Driver ID, Amount of Stops, Run Time, Distance Driven, Idle Time and Route Shape.

    The results from the empirical studies were used to define requirements for the development of a service based on the information of phase transition called transition alert service (TAS), which is the answer to RQ4. Furthermore possible stakeholders that could be interested in the transition phase information were investigated together with an examination of their needs. TAS fulfils the five main needs identified from the stakeholders: ease start and cancellation of services, avoid unnecessary telecom expenses, avoid that information goes to the wrong customer, find new customers and customize services. In order to solve this, an algorithm detecting a transition phase was developed; it was done by searching for changes in the six data types: Driver ID, Amount of Stops, Run Time, Distance Driven, Idle Time and Route Shape.

    Moreover if the TAS information is combined with other information it could be used for creating new services. Through different idea generation workshops a large number of new ideas and concepts were generated, which became the answer to RQ5. In total eleven applications for the transition alert service were developed: nine connected to change in ownership and two connected to change in utilization. Additionally, one support service named "Vehicle History" that is based on collected historical TAS was created.

    Further, one total solution named "No Worries Second-Hand" was created that includes five of the developed services. This total solution offers the customer the perfectly suitable second-hand truck without having to spend time searching for it. It also consists of a contract saying that if the customer signs a R&M contract, the dealer will buy back the vehicle and offer a new used vehicle when the old one gets too old or used. TAS makes this total solution possible by giving the dealer access to information about the truck and through this predict phase transitions.

    In conclusion, the developed services and especially the combination of them into a total solution would, according to the authors, favour the transition from a product focused company to a total solution provider, and extend the knowledge about the second-hand market.

    Pathways from research to sustainable development: Insights from ten research projects in sustainability and resilience2024In: Ambio, ISSN 0044-7447, E-ISSN 1654-7209Article in journal (Refereed)
    Abstract [en]

    Drawing on collective experience from ten collaborative research projects focused on the Global South, we identify three major challenges that impede the translation of research on sustainability and resilience into better-informed choices by individuals and policy-makers that in turn can support transformation to a sustainable future. The three challenges comprise: (i) converting knowledge produced during research projects into successful knowledge application; (ii) scaling up knowledge in time when research projects are short-term and potential impacts are long-term; and (iii) scaling up knowledge across space, from local research sites to larger-scale or even global impact. Some potential pathways for funding agencies to overcome these challenges include providing targeted prolonged funding for dissemination and outreach, and facilitating collaboration and coordination across different sites, research teams, and partner organizations. By systematically documenting these challenges, we hope to pave the way for further innovations in the research cycle.

    On applicability of time-resolved optical techniques for characterization of differently grown 3C-SiC crystals and heterostructures2012In: HETEROSIC and WASMPE 2011 / [ed] Daniel Alquier, Trans Tech Publications Inc., 2012, Vol. 711, p. 159-163Conference paper (Refereed)
    Abstract [en]

    We applied a number of time-resolved optical techniques for investigation of optical and photoelectrical properties of cubic SiC grown by different technologies on different substrates. The excess carriers were injected by a short laser pulse and their dynamics was monitored by free-carrier absorption, light-induced transient grating, and photoluminescence techniques in a wide excitation range. Combining an optical and electrical probe beam delay, we found that free carrier lifetimes in differently grown layers vary from few ns up to 20 mu s. Temperature dependences of carrier diffusivity and lifetime revealed a pronounced carrier trapping in thin sublimation grown layers. In free-standing layers and thick sublimation layers, the ambipolar mobility was found the highest (120 cm(2)/Vs at room temperature). A linear correlation between the room-temperature band edge emission and carrier lifetime in differently grown layers was attributed to defect density, strongly dependent on the used growth conditions.

    Advancing the state-of-the-art for Virtual Autopsies--initial forensic workflow study2010In: Studies in Health Technology and Informatics, ISSN 0926-9630, E-ISSN 1879-8365, Vol. 160, p. 639-643Article in journal (Refereed)
    Abstract [en]

    There are numerous advantages described of how imaging technology can support forensic examinations. However, postmortem examinations of bodies are mainly performed to address demands which differ from those of traditional clinical image processing. This needs to be kept in mind when gathering information from image data sets for forensic purposes. To support radiologists and forensic clinicians using Virtual Autopsy technologies, an initial workflow study regarding post-mortem imaging has been performed, aiming to receive an improved understanding of how Virtual Autopsy workstations, image data sets and processes can be adjusted to support and improve conventional autopsies. This paper presents potential impacts and a current forensic Virtual Autopsy workflow aiming to form a foundation for collaborative procedures that increase the value of Virtual Autopsy. The workflow study will provide an increased and mutual understanding of involved professionals. In addition, insight into future forensic workflows based on demands from both forensic and radiologist perspectives bring visualization and medical informatics researchers together to develop and improve the technology and software needed.

    Feasibility of free-breathing quantitative myocardial perfusion using multi-echo Dixon magnetic resonance imaging2020In: Scientific Reports, E-ISSN 2045-2322, Vol. 10, no 1, article id 12684Article in journal (Refereed)
    Abstract [en]

    Dynamic contrast-enhanced quantitative first-pass perfusion using magnetic resonance imaging enables non-invasive objective assessment of myocardial ischemia without ionizing radiation. However, quantification of perfusion is challenging due to the non-linearity between the magnetic resonance signal intensity and contrast agent concentration. Furthermore, respiratory motion during data acquisition precludes quantification of perfusion. While motion correction techniques have been proposed, they have been hampered by the challenge of accounting for dramatic contrast changes during the bolus and long execution times. In this work we investigate the use of a novel free-breathing multi-echo Dixon technique for quantitative myocardial perfusion. The Dixon fat images, unaffected by the dynamic contrast-enhancement, are used to efficiently estimate rigid-body respiratory motion and the computed transformations are applied to the corresponding diagnostic water images. This is followed by a second non-linear correction step using the Dixon water images to remove residual motion. The proposed Dixon motion correction technique was compared to the state-of-the-art technique (spatiotemporal based registration). We demonstrate that the proposed method performs comparably to the state-of-the-art but is significantly faster to execute. Furthermore, the proposed technique can be used to correct for the decay of signal due to T2* effects to improve quantification and additionally, yields fat-free diagnostic images.

    U.K. consensus statement on the use of extracorporeal photopheresis for treatment of cutaneous T-cell lymphoma and chronic graft-versus-host disease2008In: British Journal of Dermatology, ISSN 0007-0963, E-ISSN 1365-2133, Vol. 158, no 4, p. 659-678Article in journal (Refereed)
    Abstract [en]

    Extracorporeal photopheresis (ECP) has been used for over 30 years in the treatment of erythrodermic cutaneous T-cell lymphoma (CTCL) and over 20 years for chronic graft-versus-host disease (cGVHD). The lack of prospective randomized trials has led to different centres having different patient selection criteria, treatment schedules, monitoring protocols and patient assessment criteria. ECP for CTCL and cGVHD is available only at six specialized centres across the U.K. In the recent Improving Outcomes Guidance the National Institute for Health and Clinical Excellence endorsed the use of ECP for CTCL and because of the complexity of treatment supported its use in specialized centres and also suggested the need for expansion of this service. In 2005 consultants and senior nurses from all U.K. sites and from Scandinavia formed a Photopheresis Expert Group. This group's first aim was to produce a consensus statement on the treatment of CTCL and cGVHD with ECP using evidence-based medicine and best medical practice, in order to standardize ECP eligibility, assessment and treatment strategies across the U.K.

    Immigration policy regimes, welfare states and urban inequality patterns: A comparison between Malmo and Genoa2016In: European Urban and Regional Studies, ISSN 0969-7764, E-ISSN 1461-7145, Vol. 23, no 4, p. 862-877Article in journal (Refereed)
    Abstract [en]

    There is a general consensus that welfare states influence urban inequality patterns in cities experiencing increases in immigration. Whereas much of the existing research focused on the extent to which welfare states affect the well-being of immigrants after their admission, this study focuses on how immigration policy regimes affect the extent to which immigrant flows, and subsequent labour supply, match variations and fluctuations in the composition of demand in urban labour markets. In particular, the article develops a comparison between Malmo and Genoa, an Italian and a Swedish city with similar urban histories that display considerably different patterns of urban inequality. Immigration to Malmo was fuelled largely by humanitarian emergencies in the countries of origin and occurred in a period of economic decline for the city. The growth of the immigrant population was associated with a worsening of the labour market situation for immigrants and an increase in ethnic residential segregation. Immigration to Genoa was mainly driven by demand for cheap labour, particularly in the private-care sector. Therefore, the growth of the immigrant population was associated with an ethnic segmentation of the labour market, but it also resulted in a more dispersed distribution of immigrants than in Malmo. The differences in the urban inequality patterns in Malmo and Genoa can be only partly explained by policies affecting the living conditions of admitted immigrants. An important role has also been played by the immigration policy regimes of the two countries, which prescribed the integration potential of immigrant flows.

    Looking beyond the neighbourhood: income inequality and residential segregation in Swedish metropolitan areas, 1991–20102016In: Urban geography, ISSN 0272-3638, E-ISSN 1938-2847, Vol. 37, no 7, p. 963-984Article in journal (Refereed)
    Abstract [en]

    In recent years, residential segregation has become a major issue in the Swedish policy debate. The prevailing view is that residential segregation is a crucial contributing factor to the development of income inequality, since individual income prospects are thought to be influenced by the population characteristics of their neighbourhoods. This study takes the opposite approach and analyses the extent to which, in the period 1991–2010, rising income inequality contributed to the development of residential segregation by income in Swedish metropolitan areas. The period was characterized by unprecedented growth in income inequality, which was associated with a decline in the redistributive power of the welfare state. Residential segregation by income mirrored locally the general trend in income inequality. Another factor was the change in income dispersion in neighbourhoods, relative to the metropolitan areas as a whole, which indicates a tendency towards increased population homogeneity in neighbourhoods with respect to income.

    New Geographically Differentiated Configurations of Social Risks: Labour Market Policy Developments in Sweden and Finland2013In: Changing Social Risks and Social Policy Responses in the Nordic Welfare States / [ed] Ivan Harsløf and Rickard Ulmestig, Palgrave Macmillan, 2013, p. 220-244Chapter in book (Refereed)
    Abstract [en]

    In comparative social policy studies, Nordic welfare systems are grouped together as belonging to the same welfare model (e.g. Esping-Andersen & Korpi, 1987; Esping-Andersen, 1990; Kangas & Palme, 2005). Nordic welfare systems are known for providing allencompassing coverage of their social security systems. This coverage has traditionally included a combination of basic security and earning-related measures. In addition, the Nordic welfare systems have been characterized by the generosity of the benefits provided, by the high level of effectiveness of their income redistribution policies and by the large development of their social service infrastructures. Apart from a few exceptions (e.g. Saraceno, 2002; Lähteenmäki-Smith, 2005; Scarpa, 2009), comparative social policy studies have nevertheless also implicitly assumed that Nordic welfare systems display these ‘hallmarks’ in a geographically homogeneous manner and that, in these countries, regional variation of living conditions and also in the level of protection from social risks is minimal.

    The Emergence of a Swedish ‘Underclass’?: Welfare State Restructuring, Income Inequality and Residential Segregation in Malmö, 1991-20082013In: Economia & Lavoro, ISSN 0012-978X, E-ISSN 1827-8949, no 2, p. 121-138Article in journal (Refereed)
    Abstract [en]

    Recent political and academic debates in Sweden have been dominated by a view of urban problems as endogenously generated by the spatial concentration of individuals with similar ethnic and socioeconomic characteristics within the same neighbourhoods. The impact of welfare state retrenchment on income inequality and residential segregation instead remained an under-investigated and somehow neglected issue in recent research. This paper aims at filling this gap by analysing income inequality dynamics in Malmö in the period 1991-2008. This city offers an interesting case of analysis, given the high rates of social problems compared to other Swedish cities. The results reveal that the increase in income inequality in Malmö has been especially due to the reduced redistributive impact of the Swedish welfare state. Furthermore, the increase in residential segregation by income can be attributed to the parallel increase in citywide income inequality rather than to an alleged increase in neighbourhood sorting.

    The impact of income inequality on economic residential segregation: The case of Malmo, 1991-20102015In: Urban Studies, ISSN 0042-0980, E-ISSN 1360-063X, Vol. 52, no 5, p. 906-922Article in journal (Refereed)
    Abstract [en]

    As in other Western countries, in Sweden there is a widespread conviction that residential segregation influences the opportunities for residents social mobility and therefore is a cause of income inequality. But the opposite direction of causality, from income inequality to residential segregation, is often ignored. The paper fills this gap and analyses income inequality and economic residential segregation developments in Malmo in the years 1991-2010. During this period, changes in population composition owing to increased immigration had a negligible impact on income inequality, while the latter was primarily influenced by changes in the distribution of labour market earnings and capital incomes. At the same time, neighbourhood income inequality was predominantly driven by overall household income inequality and only to a much lower extent by the increase in residential sorting by income. Policy influencing income distribution rather than area-based strategies should thus be at the centre of current debates on residential segregation in Sweden.

    The Rescaling of Immigration and the Creation of “Areas of Outsiderness” in Sweden. The Case of Landskrona2015In: Sociologica: International Journal for Sociological Debate, E-ISSN 1971-8853, Vol. 2, p. 1-23Article in journal (Refereed)
    Abstract [en]

    In Sweden, ethnic residential segregation has been a problem associated traditionally with the largest metropolitan areas of the country. In recent years, however, growing attention has been paid to the areas of immigrant concentration located outside the largest metropolitan areas. Landskrona is one of the most renowned Swedish municipalities, among those located outside the largest metropolitan areas, in which the recent growth of the immigrant population has led to high levels of ethnic residential segregation and, therefore, to the appearance of what Swedish policymakers define as “areas of outsiderness.” Whereas Swedish debates on ethnic residential segregation are dominated by attention to the social and ethnic composition of segregated neighbourhoods, this article focuses on how immigrant settlement patterns in Landskrona have been influenced primarily by immigration policy developments over time as well as by the downscaling of this city within the Swedish urban hierarchy. In recent decades, Landskrona has in fact gone from being an economically buoyant and socially balanced industrial city into a declining and polarized city which is struggling to find a new post-industrial identity. The growth of the immigrant population in Landskrona also has been encouraged by the general unravelling of the Swedish welfare state, which has been associated with an increase in regional imbalances in economic development as well as in housing availability and affordability.

    Abstract [en]

    The chapter is structured as follows. The second section addresses the first of the two research questions and provides a brief and by no means exhaustive description of welfare state developments under the period in question. In particular, the focus is on the reforms of the Swedish income maintenance system, on both the tax and benefit sides, and on whether the implementation of these reforms produced new patterns of inequality between those who benefited and those who did not. The third section seeks to identify the rationale behind the policy-making process and to examine the motives that drove the reforms. Thereby, the attention is on the degree of consensus on the policy goals between the different political actors as well as between political and non-political actors. The fourth section illustrates the case study of Stockholm Metropolitan Area and examines the impact of welfare reforms on income differences between different groups (defined by employment status and ethnic background) and between neighbor hoods with different population composition. The fifth and last section reviews the main conclusions and attempts to answer the question that titles this chapter.

    Abstract [en]

    Until recently, comparative social policy research remained strongly influenced bymethodological nationalism (i.e. an approach equating social boundaries with stateboundaries) and has rarely considered immigration-driven changes in welfare states. Yet,over the past decades, immigrant populations have grown in size and become increasing­ly diversified, both in terms of origin countries and in terms of integration patterns, in allWestern countries. Immigrants are a more visible, but also contested, presence in West­ern societies, which affects also the development of the national labour market and wel­fare systems. This chapter focuses on the link between immigration-driven ethnic diversi­ty and welfare state development by considering four interrelated issues: (1) how the pat­terns of immigrants’ labour market incorporation in host societies affect the social rightsthey are entitled to; (2) how increasing international migration contributed to the recon­figuration of care arrangements; (3) the implications of immigration-driven multicultural­ism for welfare state sustainability; and (4) the connection between immigration and pub­lic support for the welfare state. Then, we narrow down our analysis by providing a moredetailed account of recent development of migration policies in some European countries.Based on the analysis of the country cases, we put forward the argument that recent in­stitutional developments point to an ‘Americanization’ of European migration policy and,therefore, to an increasing ‘racialization’ of European welfare states.

    Who Undermines the Welfare State? Austerity-Dogmatism and the U-Turn in Swedish Asylum Policy2018In: Social Inclusion, ISSN 2183-2803, E-ISSN 2183-2803, Vol. 6, no 1, p. 199-207Article in journal (Refereed)
    Abstract [en]

    Within the EU, the so-called “refugee crisis” has been predominantly dealt with as an ill-timed and untenable financial burden. Since the 2007-08 financial crisis, the overarching objective of policy initiatives by EU-governments has been to keep public expenditure firmly under control. Thus, Sweden’s decision to grant permanent residence to all Syrians seeking asylum in 2013 seemed to represent a paradigmatic exception, pointing to the possibility of combining a humanitarian approach in the “long summer of migration” with generous welfare provisions. At the end of 2015, however, Sweden reversed its asylum policy, reducing its intake of refugees to the EU-mandated minimum. The main political parties embraced the mainstream view that an open-door refugee policy is not only detrimental to the welfare state, but could possibly trigger a “system breakdown”. In this article, we challenge this widely accepted narrative by arguing that the sustainability of the Swedish welfare state has not been undermined by refugee migration but rather by the Swedish government’s unbending adherence to austerity politics. Austerity politics have weakened the Swedish welfare state’s socially integrative functions and prevented the implementation of a more ambitious growth agenda, harvesting a potentially dynamic interplay of expansionary economic policies and a humanitarian asylum policy.

    Is migration bad for welfare?: reconfigurations of welfare, labour and citizenship in Sweden2019In: Inequalitities and migration: challenges for the Swedish welfare state / [ed] Sven Trygged & Erica Righard, Lund: Studentlitteratur AB, 2019, p. 31-52Chapter in book (Other academic)
    Abstract [sv]

    The aim of this chapter is to challenge an axiomatic assumption made in current public debates, namely that the sustainability of the welfare state in an age of globalization requires the imposition of limits on immigration. With a particular focus on Sweden and recent changes of Swedish welfare policy, the chapter shows how the current crisis of the Swedish welfare model has in fact haunted this model for decades. The argument presented is that the socially-integrative capacities of the Swedish model had been compromised well before the start of the post-2015 refugee crisis in Europe. The argument made is that it was not the scale of immigration that made the Swedish welfare state unsustainable. Rather, it is the austerity-driven retrenchment of the Swedish welfare state that, in the past quarter of a century, has steadily undermined the capacity of the welfare model to offer emancipatory and non-discriminatory pathways of incorporation to immigrants. With the neoliberal reforms implemented since the early 1990s, the current reality in Sweden is that of deepening, and increasingly ethnically tinged, class divisions and long-term social exclusion of sizeable population groups from substantial citizenship rights.

    The Effects of a retention interval and refresher session on intracorporeal suturing and knot tying skill and mental workload2017In: Surgery, ISSN 0039-6060, E-ISSN 1532-7361, Vol. 161, no 5, p. 1209-1214Article in journal (Refereed)
    Abstract [en]

    Background. The effects of refraining from practice for different intervals on laparoscopic suturing and mental workload was assessed with a secondary task developed by the authors. We expected the inability to practice to produce a decrease in performance on the suturing, knot tying, and secondary task and skills to rebound after a single refresher session.

    Methods. In total, 22 surgical assistant and premedical students trained to Fundamentals of Laparoscopic Surgery proficiency in intracorporeal suturing and knot tying were assessed on that task using a secondary task. Participants refrained from practicing any Fundamentals of Laparoscopic Surgery tasks for 1 or 5 months. At the time of their return, they were assessed immediately on suturing and knot tying with the secondary task, practiced suturing and knot tying for 40 minutes, and then were reassessed.

    Results. The mean suture times from the initial reassessment were greater than the proficiency times but returned to proficiency levels after one practice session, F(2, 40) = 14.5, P < .001, partial h2 = .420. Secondary task scores mirrored the results of suturing time, F(2, 40) = 6.128, P < .005, partial h2 = .235, and were moderated by retention interval.

    Conclusion. When participants who reached proficiency in suturing and knot tying were reassessed after either 1or 5 months without practice, their performance times increased by 35% and secondary task scores decreased by 30%. These deficits, however, were nearly reversed after a single refresher session.

    Engineering characteristics of autonomous agent architectures2000In: Journal of experimental and theoretical artificial intelligence (Print), ISSN 0952-813X, E-ISSN 1362-3079, Vol. 12, no 2, p. 191-212Article in journal (Refereed)
    Abstract [en]

    As the science of building agents and agent based applications improves, agents are gradually making the transition from research laboratory prototypes to industrial applications. In an industrial setting pragmatic engineering issues related to the development and maintenance of agents come to the fore. In this paper a list of important engineering characteristics of agent architectures is presented. The list has the dual aims of providing evaluation criteria for agent users and design issues for agent architecture designers. Evaluation of an architecture with respect to the presented characteristics will allow industrial project managers to better assess the trade offs between architectures. Designing architectures that better fulfill the characteristics should lead to more industrially relevant architectures and successful agent applications. This list is designed to start discussion and raise awareness of industrial issues. It is hoped that over time good metrics and an evaluation methodology evolve which provide a robust framework for evaluating agent architectures with respect to industrial concerns.

    Agents are an artificial intelligence technique of encapsulating a piece of pro-active, autonomous, intelligent software in a module that senses and acts in its environment. As the technology underlying sophisticated multi-agent systems improves, such systems are being deployed in ever more complex domains and are being given ever more responsibility for more critical tasks. However, multi-agent technology brings with it not only the potential for better, more efficient systems requiring less human involvement but also the potential to cause harm to the system's human users. One way of mitigating the potential harm an intelligent multi-agent system can do is via the use of adjustable autonomy. Adjustable autonomy is the idea of dynamically changing the autonomy of agents in a multi-agent system depending on the circumstances. Decision making control is transferred from agents to users when the potential for costly agent errors is large.

    We believe that the design of the agents in a multi-agent system impacts the difficulty with which the system's adjustable autonomy mechanisms are implemented. Some features of an agent will make the implementation of adjustable autonomy easier, while others will make it more difficult. The central contribution of this thesis is a set of guidelines for the design of agents which, if followed, lead to agents which make adjustable autonomy straightforward to implement. In addition, the guidelines lead to agents from which it is straightforward to extract useful information and whose autonomy may be changed in a straightforward manner.

    The usefulness of the guidelines is shown in the design of the agents for two systems with adjustable autonomy. The first system is EASE, which is used for creating intelligent actors for interactive simulation environments. The second system is the E-Elves which is a multiagent system streamlining the everyday coordination tasks of a human organisation. An evaluation of the two systems demonstrates that following the guidelines leads to agents that make effective adjustable autonomy mechanisms easier to implement.

    A user oriented system for developing behavior based agents1999In: RoboCup-98: Robot Soccer World Cup II / [ed] Minoru Asada and Hiroaki Kitano, Berlin: Springer Berlin/Heidelberg, 1999, Vol. 1604, p. 173-186Chapter in book (Refereed)
    Abstract [en]

    Developing agents for simulation environments is usually the responsibility of computer experts. However, as domain experts have superior knowledge of the intended agent behavior, it is desirable to have domain experts directly specifying behavior. In this paper we describe a system which allows non-computer experts to specify the behavior of agents for the RoboCup domain. An agent designer is presented with a Graphical User Interface with which he can specify behaviors and activation conditions for behaviors in a layered behavior-based system. To support the testing and debugging process we are also developing interfaces that show, in real-time, the world from the agents perspective and the state of its reasoning process.

    End user specification of RoboCup teams2000In: RoboCup-99: Robot Soccer World Cup III / [ed] Manuela Veloso, Enrico Pagello and Hiroaki Kitano, Springer Berlin/Heidelberg, 2000, Vol. 1856, p. 450-459Chapter in book (Refereed)
    Abstract [en]

    Creating complex agents for simulation environments has long been the exclusive realm of AI experts. However it is far more desirable that experts in the particular application domain, rather than AI experts, are empowered to specify agent behavior. In this paper an approach is presented that allows domain experts to specify the high-level team strategies of agents for RoboCup. The domain experts' specifications are compiled into behavior based agents. The 1999 RoboCup World Cup provided an interesting basis for evaluation of the approach. We found that for RoboCup it is not necessary to allow a user to change low level aspects of the agents' behavior in order for them to create a range of different, interesting teams. We also found that the modular nature of behavior based architectures make them an ideal target architecture for compiling enduser specifications.

    Headless Chickens III2000In: RoboCup-99: Robot Soccer World Cup III / [ed] Manuela Veloso, Enrico Pagello and Hiroaki Kitano, Springer Berlin/Heidelberg, 2000, Vol. 1856, p. 576-579Chapter in book (Refereed)
    Abstract [en]

    The development of the Headless Chickens III emphasized a high level team specification environment, called the Strategy Editor, that was intended for use by endusers, rather than computer programmers[2]. Using the strategy editor consisted of placing players on a image of the ground and indicating the direction(s) the player should kick and/or dribble when they get the ball. Different player formations and passing/dribbling patterns could be specified for different game situations. The designer could also specify the style of play for each of the players, e.g. defensive or inclined to shoot or dribble.

    Standardized evaluation methodology and reference database for evaluating coronary artery centerline extraction algorithms2009In: Medical Image Analysis, ISSN 1361-8415, E-ISSN 1361-8423, Vol. 13, no 5, p. 701-714Article in journal (Refereed)
    Abstract [en]

    Efficiently obtaining a reliable coronary artery centerline from computed tomography angiography data is relevant in clinical practice. Whereas numerous methods have been presented for this purpose, up to now no standardized evaluation methodology has been published to reliably evaluate and compare the performance of the existing or newly developed coronary artery centerline extraction algorithms. This paper describes a standardized evaluation methodology and reference database for the quantitative evaluation of coronary artery centerline extraction algorithms. The contribution of this work is fourfold: (1) a method is described to create a consensus centerline with multiple observers, (2) well-defined measures are presented for the evaluation of coronary artery centerline extraction algorithms, (3) a database containing 32 cardiac CTA datasets with corresponding reference standard is described and made available, and (4) 13 coronary artery centerline extraction algorithms, implemented by different research groups, are quantitatively evaluated and compared. The presented evaluation framework is made available to the medical imaging community for benchmarking existing or newly developed coronary centerline extraction algorithms.

    A UNIFIED APPROACH TO THE HELIOSEISMIC INVERSION PROBLEM OF THE SOLAR MERIDIONAL FLOW FROM GLOBAL OSCILLATIONS2011In: Astrophysical Journal, ISSN 0004-637X, E-ISSN 1538-4357, Vol. 734, no 2, p. 97-Article in journal (Refereed)
    Abstract [en]

    Measurements from tracers and local helioseismology indicate the existence of a meridional flow in the Sun with strength in the order of 15 m s(-1) near the solar surface. Different attempts were made to obtain information on the flow profile at depths up to 20 Mm below the solar surface. We propose a method using global helioseismic Doppler measurements with the prospect of inferring the meridional flow profile at greater depths. Our approach is based on the perturbation of the p-mode eigenfunctions of a solar model due to the presence of a flow. The distortion of the oscillation eigenfunctions is manifested in the mixing of p-modes, which may be measured from global solar oscillation time series. As a new helioseismic measurement quantity, we propose amplitude ratios between oscillations in the Fourier domain. We relate this quantity to the meridional flow and unify the concepts presented here for an inversion procedure to infer the meridional flow from global solar oscillations.

    Grupparbete i skolans naturvetenskapliga ämnen: En kvalitativ studie om några NO-lärares uppfattningar av grupparbete som arbetsform2004Independent thesis Advanced level (degree of Magister)Student thesis
    Abstract [en]

    This qualitative study investigates teacher´s experiences with and opinions of using collaboration in science education. A selected group of science teachers tutoring in compulsory school were interviewed in an open form using a set of pre-defined questions. The study resulted in four categories of teacher responses using a phenomenographical method of category sorting

    Collaboration in Science to make it more approachable and understandable

    Collaboration in Science to enrich the learning process

    Collaboration in Science because the teacher “has to”

    Collaboration in Science due to economical limitations

    Our study shows that the respondents have different receptions about the term collaboration resulting in differences in the implementation of collaboration exercises. Our categories shed light on these differences.

    Data-driven business and data privacy: Challenges and measures for product- based companies2023In: Business Horizons, ISSN 0007-6813, E-ISSN 1873-6068, Vol. 66, no 4, p. 493-504Article in journal (Refereed)
    Abstract [en]

    To leverage the opportunities provided by the Internet of Things (IoT), product-based companies are exploring new data-driven business opportunities. They may miss these same opportunities, however, owing to data-privacy chal-lenges. These challenges start with the customers of product-based companies, extend to the wider business ecosystem, and continue with the companies them-selves. This article identifies 12 data-privacy challenges and introduces 12 mea-sures to address them. These include intuitive recommendations, such as enabling cross-product consent collection, as well as less intuitive measures, such as fostering a can-do attitude in legal units, closing the gap between legal and busi-ness initiatives, or implementing a clear process for well-reasoned risk-taking. The following four principles were found to support companies in implementing these measures: (1) letting privacy and data-driven business go hand in hand, (2) putting customers first and turning their privacy preferences into opportunities, (3) aligning risk-management activities with the process of digital service development, and (4) using technology to professionalize legal processes.& COPY; 2022 Kelley School of Business, Indiana University.

    Biological diversity versus risk for mosquito nuisance and disease transmission in constructed wetlands in southern Sweden2004In: Medical and Veterinary Entomology, ISSN 0269-283X, E-ISSN 1365-2915, Vol. 18, no 3, p. 256-267Article in journal (Refereed)
    Abstract [en]

    In southern Sweden, many wetlands have been constructed, and maintaining or increasing biological diversity is often included in the aims. Some wetlands are constructed near human settlements, thus raising the problem of wetlands being associated with mosquitoes (Diptera: Culicidae). Increased biodiversity (including mosquito diversity) is considered desirable, whereas mosquito nuisance from a human point of view is not. Adult mosquito abundance, diversity and species assemblages of constructed wetlands were compared to natural wetlands. The potential of constructed wetlands for mosquito nuisance and transmission of mosquito-borne viruses was evaluated. The study areas included five constructed and four natural wetlands. Mosquito abundance and species richness were higher in the natural than in the constructed wetlands, and showed a positive correlation with wetland size. Mosquito species assemblages formed three clusters, which were not explained by origin, size and water permanence of wetlands. In a redundancy analysis, however, mosquito faunas showed significant relationships with these variables, and size and origin of wetlands were most important. Major nuisance species (multivoltine species feeding on mammals and laying eggs on soil) were found in all wetlands, although in relatively low numbers. Risk assessment for Sindbis virus transmission showed moderate risk for two constructed wetlands near human settlements. It is concluded that small size of constructed wetlands has the advantage of low mosquito numbers from a human point of view. The use of functional groups is recommended as a tool for presenting mosquito data to the public, and for helping communication between scientists and administrative decision makers.
