A micromachined dual-axis actuator for Use in a miniaturized optical communication system
- 2008
-
In: Proceeding of the International Astronautical Congress, Sep 29 - Oct 3, Glasgow, Scotland.
-
Conference paper (peer-reviewed)abstract
- A micromachined beam-steering device for use in a miniaturized free-space optical communication system is presented. This device is part of a communication system intended for microspacecraft flying in kilometer-sized formations. Central to it, is a laser-reflecting mirror tiltable in two orthogonal directions using electrothermal actuators based on heating of a polymer confined in silicon v-grooves. The device is fabricated using standard microstructure technology. Successful experiments show a maximum mechanical scan range of 19º in two orthogonal directions. The voltages applied are below 100 V, and the power consumption is less than 2.4 W. Thermal coupling between orthogonal joints has been investigated with infrared imaging. The overall results are very promising, and improvement in the design and fabrication can be suggested.

Comparison of reduced order doubly fed induction generator models for nonlinear analysis
- 2009
-
In: 2009 IEEE Electrical Power and Energy Conference, EPEC 2009. - 9781424445080
-
Conference paper (peer-reviewed)abstract
- This article compares the behaviour of different order models, for large scale wind farms comprising doubly fed induction generators (DFIGs). While it is important to have a model which is detailed enough that all interesting phenomena can be examined, it is also important to have simple models, not only to reduce computation time, but also to simplify the design of controllers. This article compares the characteristics of different order models for DFIGs and their responses to control. Eigenvalue analysis and numerical simulations are used to compare the characteristics of the different order models.

The use of evaluation power in a decentralized education system. The case of Sweden
- 2015
-
Conference paper (peer-reviewed)abstract
- The purpose of this paper is to explore and discuss the role of evaluation in local school governance. Local school governance refers to all the public and private school actors’ and institutions’ (e.g. education committees, school principals and parents) governing of schools and education.The applied framework takes departure in governance research and research on evaluation and governance. The role of the municipality in a country’s education system largely depends on the division of power between levels of government, and the mandate and discretion given to local governments and school providers. The discretion also varies depending on changes in national school governance and other factors such as being subjected to global education governance as a member of the EU and OECD. The governance structure and mode of governance embeds and steers evaluation and how governance and evaluation should interplay.A close look at evaluation in Sweden, based on a case study of four Swedish municipalities, is an illustrative case as the education evaluation arena is overcrowded and the decentralised education system provides freedom of choice that allow local governments and school providers to use their evaluation power differently.The results show e.g. that politicians develop and use local evaluation systems to maintain its governance model and govern schools to enhance achievement of national and local policy objectives, and comply with or question critique from school inspections. Teachers, subjected to increased accountability pressure, do not use external evaluations for improving teaching. Only their own informal evaluations serve that purpose.

Introduction
- 2012
-
In: Biodiversity in Dead Wood. - : Cambridge University Press. - 9781139025843 ; , s. 1-9
-
Book chapter (peer-reviewed)abstract
- This book is about life in dead trees. All over the world one can find a fascinating diversity of life forms in decaying wood – first and foremost a wide variety of fungi and insects. These organisms carry out the hidden but highly important work of wood decomposition. A fundamental question frequently revisited in this book is: ‘Why is the species diversity of wood-inhabiting organisms so tremendously high?’ In most chapters we approach this question indirectly by highlighting the key properties of dead wood, along with the environmental factors and processes that bring about the diversity we can observe. We also discuss species richness explicitly in Chapter 11. There are at least two good reasons for addressing the biodiversity in dead wood. One is that the diversity of wood-inhabiting organisms is a multifaceted and interesting phenomenon that deserves attention for its own sake. Another reason is that this diversity is being seriously threatened due both to the loss and fragmentation of forests and because of the greatly reduced amount of dead wood in managed forests and other woodlands. Thus, we need to understand the role of dead wood for biodiversity in order to manage and maintain it while efficiently utilizing forest resources.

Fair and Square: A Retention Model of Managerial Compensation
- 2022
-
In: Management Science. - : INFORMS (Institute for Operations Research and Management Sciences). - 1526-5501 .- 0025-1909. ; 68:5, s. 3604-3624
-
Journal article (peer-reviewed)abstract
- We propose a model of how the retention motive shapes managerial compensation contracts. Once employed, a risk-averse manager acquires imperfectly portable skills whose value is stochastic because of industry-wide demand shocks. The manager's actions are uncontractible, and the perceived fairness of the compensation contract affects the manager's motivation. If the volatility of profits is sufficiently large and outside offers are suffi-ciently likely, the equilibrium contract combines a salary with an own -firm stock option. The model's predictions are consistent with empirical regularities concerning contractual shape, the magnitude of variable pay, the lack of indexation, and the prevalence of discretionary severance pay.

Book chapter (peer-reviewed)abstract
- This chapter focuses on the coming together in particular situations of a number of the main trends identified earlier in the book relating to globalization and the growth of the knowledge economy. The interplay of these tendencies is examined within the context of local education policy and local economic development. A weaving together of education and economic development as a consequence of the increasing importance of knowledge in the global competitive economy has been apparent not only at the national but also at the local level. The more traditional definition of local development in terms of economic, technical and physical infrastructure has been challenged by the emergence of a parallel, more holistic development discourse in which education, health, care, culture, environment, and other quality of life issues contribute to an interactive creation of welfare and growth. Social, economic and environmental goals are linked and balanced and the importance of knowledge creation and human resource development in achieving economic development are acknowledged. access to knowledge, ideas, new technology, suppliers and customers, its ‘soft’ enabling infrastructure, are increasingly important.

Synthesis of the Bioactive Benzochromenes Pulchrol and Pulchral, Metabolites of Bourreria pulchra
- 2014
-
In: European Journal of Organic Chemistry. - : Wiley. - 1434-193X. ; 2014:8, s. 1594-1596
-
Journal article (peer-reviewed)abstract
- The parasites Leshmania mexicana and Trypanosoma cruzi cause serious health problems, and few efficient treatments are available. Recently, the two benzochromenes pulchrol (1) and pulchral (2) were reported from the roots of Bourreria pulchra, and especially 1 but also 2 was found to be active towards the parasites. In this paper, we present a total synthesis of 1 and 2 to facilitate their biological evaluation. The synthesis is mild, short, and high yielding and suitable for a structure-activity relationship study.

Resourceful utilization of quarry tailings in the preparation of non-sintered high-strength lightweight aggregates
- 2022
-
In: Construction and Building Materials. - : Elsevier BV. - 0950-0618. ; 334
-
Journal article (peer-reviewed)abstract
- Quarry tailings are usually stockpiled due to stable crystalline structures below 100 °C and abundant sources, which lead to a serious environmental impacts and high ecological risks. This paper presents a study of transforming the fly ash and quarry tailings as the main raw materials into lightweight aggregates (LWAs) for using in civil engineering. A novel curing regime (autoclave technology) has been proposed to obtain higher compressive strength of LWAs. The effects of curing parameters (including temperature and steam pressure) on the properties (compressive strength, water absorption, loose bulk density, phase composition, pore structure and microstructure) of LWAs were systematically evaluated. On the other hand, this research also studies the effect of cement content on the basic properties of LWAs, which was decreased from 30 to 10 wt% for declining the CO2 emission. Results show that the strength sharply increases from 2.48 to 11.95 MPa and the water absorption decreases from 11.2 to 2.09% with increasing the elevated curing temperature from 25 to 190 °C. The LWA prepared with 70 wt% solid wastes (fly ash and quarry tailings) at 190 °C achieved the highest strength (11.95 MPa) and the lower loose bulk density (1160 kg/m3), which could meet the requirement of Chinese LWAs standard (GB/T 17431.1-2010). The water absorption of LWAs is below 5% except sample T25. The total porosity of LWAs decreases from 39.65% to 26.32% at 150 °C and from 42.54% to 27.24% at 190 °C while the cement content increases form 10 wt% to 30 wt%. At the same time, the percentage of pores (>50 nm) also gradually decreases. While the curing temperature, pressure and cement usage are above 150 °C, 1.00 MPa and 10 wt% respectively, will promote the formation of new phase composition (analcime). That also further increases the strength and percentage of harmless pores and few harmful pores. Therefore, this research offers a new curing method for producing LWAs from 70 to 90 wt% solid waste and is a rapid and sustainable solution for the large-scale recycling of quarry tailings.

Journal article (peer-reviewed)abstract
- Background: Irritable bowel syndrome (IBS) is a complex condition with multiple factors contributing to its aetiology and pathophysiology. Aetiologically these include genetics, life-time events and environment, and physiologically, changes in motility, central processing, visceral sensitivity, immunity, epithelial permeability and gastrointestinal microflora. Such complexity means there is currently no specific reliable biomarker for IBS, and thus IBS continues to be diagnosed and classified according to symptom based criteria, the Rome Criteria. Carefully phenotyping and characterisation of a ‘large’ pool of IBS patients across Europe and even the world however, might help identify sub-populations with accuracy and consistency. This will not only aid future research but improve tailoring of treatment and health care of IBS patients. Purpose: The aim of this position paper is to discuss the requirements necessary to standardize the process of selecting and phenotyping IBS patients and how to organise the collection and storage of patient information/samples in such a large multi-centre pan European/global study. We include information on general demographics, gastrointestinal symptom assessment, psychological factors, quality of life, physiological evaluation, genetic/epigenetic and microbiota analysis, biopsy/blood sampling, together with discussion on the organisational, ethical and language issues associated with implementing such a study. The proposed approach and documents selected to be used in such a study was the result of a thoughtful and thorough four-year dialogue amongst experts associated with the European COST action BM1106 GENIEUR (www.GENIEUR.eu). © 2016 John Wiley & Sons Ltd

Kennedy Classification and Treatment Options : A Study of Partially Edentulous Patients Being Treated in A Specialized Prosthetic Clinic
- 2012
-
In: Journal of Prosthodontics. - : Wiley-Blackwell. - 1059-941X .- 1532-849X. ; 21:3, s. 177-180
-
Journal article (peer-reviewed)abstract
- Purpose: This study was done under the auspices of the Swedish International Development Cooperation Agency, whose aim is to improve living conditions in developing countries, including dental aid. Each year the number of medical staff from the European Union willing to help in developing countries increases, and it is thus important to highlight issues of development. From the Middle Asian region, the Republic of Kazakhstan was chosen. At present, few studies have evaluated the prevalence of various types of partial edentulism in this region, and no research has investigated the prosthetic treatment choice in the various types of partial edentulism. The purpose of this study was to determine (i) the prevalence of various types of partial edentulism in patients seeking dental care and (ii) the type of prosthetic restoration most commonly chosen to treat these patients. Materials and Methods: One hundred twelve patient records, together with panoramic radiographs, were studied. Various types of partial edentulism were grouped into four Kennedy classes. Patient records were used to examine which treatment option was chosen for each patient. Results: The most prevalent type of partial edentulism in this patient sample was Kennedy type III, in both the maxilla (50.0%) and the mandible (41.1%). Partial edentulism was most frequently managed by fixed partial dentures (FPDs) in both jaws. Kennedy IV was the least prevalent (7.1% in the maxilla, 5.6% in the mandible) and in most cases treated with removable partial dentures (RPDs) in both jaws. Conclusion: Our results are consistent with previous research on the prevalence of Kennedy classes in Kazakhstan. RPDs were the most common type of prosthetic management for partial edentulism.

Reactions of C+ + Cl-, Br-, and I--A comparison of theory and experiment
- 2019
-
In: Journal of Chemical Physics. - : AIP Publishing. - 0021-9606 .- 1089-7690. ; 151:24
-
Journal article (peer-reviewed)abstract
- Rate constants for the reactions of C+ + Cl-, Br-, and I- were measured at 300 K using the variable electron and neutral density electron attachment mass spectrometry technique in a flowing afterglow Langmuir probe apparatus. Upper bounds of <10(-8) cm(3) s(-1) were found for the reaction of C+ with Br- and I-, and a rate constant of 4.2 +/- 1.1 x 10(-9) cm(3) s(-1) was measured for the reaction with Cl-. The C+ + Cl- mutual neutralization reaction was studied theoretically from first principles, and a rate constant of 3.9 x 10(-10) cm(3) s(-1), an order of magnitude smaller than experiment, was obtained with spin-orbit interactions included using a semiempirical model. The discrepancy between the measured and calculated rate constants could be explained by the fact that in the experiment, the total loss of C+ ions was measured, while the theoretical treatment did not include the associative ionization channel. The charge transfer was found to take place at small internuclear distances, and the spin-orbit interaction was found to have a minor effect on the rate constant.

Generative lessons of exclusion : re-considering everyday-living experience and approaching its meaningful description
- 1999
-
Doctoral thesis (other academic/artistic)abstract
- Generally addressed in this dissertation writing are the problematic of everyday experience as an empirical social science concern, the problematic of social science as an everyday pedagogical experience, the topic of sense formation as a generative psycho-social event, and the topic of intersubjectivity as meaningful social unity. Generally offered is an alternative understanding, approach and method for a particular kind of qualitative social science inquiry treating everyday experience and shared experience, the kind enlisting experiencer accounts and aiming to describe associated experiencer meanings. The problematics, topics and methodology considerations are presented by way of an account of the dissertation situation, process and result occurrences. The account is provided in the form of critical and suggestive discussions around an attempted empirical phenomenology study of foreigner exclusion experiences in Sweden and the explications of various other orientations and approaches regarding the matter of everyday experience. The account delivery involves a regressive effort consisting of a questioning back, and the account formulation involves an experimental writing consisting of a "conversational re-presentation." The point of departure for the questioning back is the emergence of the alternative understanding comprising the main project result, an understanding which came to be generated by way of some re-considerational work associated with the attempted study. This work took place in a way characterized as relatively "consequential" and "conversational," and not only the included content but the particular way by which the work proceeded and the result emerged are emphasized as having significantly influenced the character of the understanding gained. The re-considerational effort is considered to exemplify its result. The main source of influence for the experimental writing is also the emergent alternative understanding, where the characteristics of generativity, consequentiality and conversationality are stressed.The alternative understanding offered may be expressed, in short, as "syncretic generativity." This expression addresses both the matter of everyday-living experience and the matter of approaching its meaningful description. It expresses, more specifically, a suggested attitude and mode of everyday-living experience and a suggested approach and method for experiential meaning description. "Syncretic generativity" may be characterized, in short, as a situational nexus of interactive co-contributing influences generating a trans-formational re-presentational result.

Irregular stimulus distribution increases the negative footprint illusion
- 2022

Journal article (peer-reviewed)abstract
- As a climate change mitigation strategy, environmentally certified ‘green’ buildings with low carbon footprints are becoming more prevalent in the world. An interesting psychological question is how people perceive the carbon footprint of these buildings given their spatial distributions in a given community. Here we examine whether regular distribution (i.e., buildings organized in a block) or irregular distribution (i.e., buildings randomly distributed) influences people's perception of the carbon footprint of the communities. We first replicated the negative footprint illusion, the tendency to estimate a lower carbon footprint of a combined group of environmentally certified green buildings and ordinary conventional buildings, than the carbon footprint of the conventional buildings alone. Importantly, we found that irregular distribution of the buildings increased the magnitude of the negative footprint illusion. Potential applied implications for urban planning of green buildings are discussed.

Long-range angular correlations of pi, K and p in p-Pb collisions at root s(NN)=5.02 TeV
- 2013
-
In: Physics Letters. Section B: Nuclear, Elementary Particle and High-Energy Physics. - : Elsevier BV. - 0370-2693. ; 726:1-3, s. 164-177
-
Journal article (peer-reviewed)abstract
- Angular correlations between unidentified charged trigger particles and various species of charged associated particles (unidentified particles, pions, kaons, protons and antiprotons) are measured by the ALICE detector in p-Pb collisions at a nucleon-nucleon centre-of-mass energy of 5.02 TeV in the transverse-momentum range 0.3 < p(T) < 4 GeV/c. The correlations expressed as associated yield per trigger particle are obtained in the pseudorapidity range vertical bar n(lab)vertical bar < 0.8. Fourier coefficients are extracted from the long-range correlations projected onto the azimuthal angle difference and studied as a function of p(T) and in intervals of event multiplicity. In high-multiplicity events, the second-order coefficient for protons, 4, is observed to be smaller than that for pions, v(2)(pi), up to about p(T) = 2 GeV/c. To reduce correlations due to jets, the per-trigger yield measured in low-multiplicity events is subtracted from that in high-multiplicity events. A two-ridge structure is obtained for all particle species. The Fourier decomposition of this structure shows that the second-order coefficients for pions and kaons are similar. The v(2)(p) is found to be smaller at low P-T and larger at higher p(T) than v(2)(pi), with a crossing occurring at about 2 GeV/c. This is qualitatively similar to the elliptic-flow pattern observed in heavy-ion collisions. A mass ordering effect at low transverse momenta is consistent with expectations from hydrodynamic model calculations assuming a collectively expanding system. (C) 2013 CERN.

Harmonic microchip acoustophoresis: a route to online raw milk sample precondition in protein and lipid content quality control
- 2009
-
In: Analytical Chemistry. - : American Chemical Society (ACS). - 1520-6882 .- 0003-2700. ; 81:15, s. 6195-6200
-
Journal article (peer-reviewed)abstract
- A microfluidic approach for raw milk sample preconditioning prior to protein and lipid content analysis has been developed. The system utilizes microchip acoustophoresis and is a further extension of our previously reported multiple node ultrasonic standing wave focusing platform ( Grenvall , C. , Augustsson , P. , Matsuoka , H. and Laurell , T. Proc. Micro Total Anal. Syst. 2008 , 1, 161-163 ). The microfluidic approach offers a method for rapid raw milk quality control using Fourier transform infrared spectroscopy (FT-IR). Two acoustophoresis modes are explored, 2 lambda/2 and 3 lambda/2, offering lipid content enrichment or depletion, respectively. Lipid content depletion above 90% was accomplished. FT-IR data on microchip-processed raw milk samples, enabling direct lipid and protein content analysis, are reported. Most importantly, the harmonic operational modes bypass the problem of lipid aggregation and subsequent clogging, inherent in lambda/2 acoustophoresis systems.

Functional Recruitment of Human Complement Inhibitor C4b-Binding Protein to Outer Membrane Protein Rck of Salmonella
- 2011
-
In: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 6:11
-
Journal article (peer-reviewed)abstract
- Resistance to complement mediated killing, or serum resistance, is a common trait of pathogenic bacteria. Rck is a 17 kDa outer membrane protein encoded on the virulence plasmid of Salmonella enterica serovars Typhimurium and Enteritidis. When expressed in either E. coli or S. enterica Typhimurium, Rck confers LPS-independent serum resistance as well as the ability to bind to and invade mammalian cells. Having recently shown that Rck binds the inhibitor of the alternative pathway of complement, factor H (fH), we hypothesized that Rck can also bind the inhibitor of the classical and lectin pathways, C4b-binding protein (C4BP). Using flow cytometry and direct binding assays, we demonstrate that E. coli expressing Rck binds C4BP from heat-inactivated serum and by using the purified protein. No binding was detected in the absence of Rck expression. C4BP bound to Rck is functional, as we observed factor I-mediated cleavage of C4b in cofactor assays. In competition assays, binding of radiolabeled C4BP to Rck was reduced by increasing concentrations of unlabeled protein. No effect was observed by increasing heparin or salt concentrations, suggesting mainly non-ionic interactions. Reduced binding of C4BP mutants lacking complement control protein domains (CCPs) 7 or 8 was observed compared to wt C4BP, suggesting that these CCPs are involved in Rck binding. While these findings are restricted to Rck expression in E. coli, these data suggest that C4BP binding may be an additional mechanism of Rck-mediated complement resistance.

Regularization in Medical Image Registration using Global Linear Optimization
-
Other publication (other academic/artistic)abstract
- Common problems in image registration include having large parts of the images contain noisy, uncertain, missing or impossible motion. Regularization is the field that aims to overcome these problems. In this article, we propose a novel framework : Global Linear Optimization (GLO) which we demonstrate has the capabilities to simultaneously and globally regularize with respect to : (1) anisotropic certainty of prior motion field, (2) sliding of organ boundaries and (3) incompressibility of organ interiors. The power of the presented framework consists of being able to spatially adapt which subsets of the data each constraint should affect and then solve a large sparse linear equations system which automatically propagates a solution over the data set through an overlapping localized metric. We demonstrate the validity of the methods and the power of the GLO framework on relevant test cases and on medical data from the DIR-lab.

Organisation and Communication Problems in Automotive Requirements Engineering
- 2018
-
In: Requirements Engineering. - : Springer Science and Business Media LLC. - 0947-3602 .- 1432-010X. ; 23:1, s. 145-167
-
Journal article (peer-reviewed)abstract
- Project success in the automotive industry is highly influenced by Requirements Engineering (RE), for which communication and organisation structure play a major role, much due to the scale and distribution of these projects. However, empirical research is scarce on these aspects of automotive RE and warrants closer examination. Therefore, the purpose of this paper is to identify problems or challenges in automotive RE with respect to communication and organisation structure. Using a multiple-case study approach, we collected data via 14 semi-structured interviews at one car manufacturer and one supplier. We tested our findings from the case study with a questionnaire distributed to practitioners in the automotive industry. Our results indicate that it is difficult but increasingly important to establish communication channels outside the fixed organisation structure and that responsibilities are often unclear. Product knowledge during early requirements elicitation and context knowledge later on is lacking. Furthermore, abstraction gaps between requirements on different abstraction levels leads to inconsistencies. For academia, we formulate a concrete agenda for future research. Practitioners can use the findings to broaden their understanding of how the problems manifest and to improve their organisations.

How Did We Miss This? : A Case Study on Unintended Biases in Robot Social Behavior
- 2023
-
In: HRI 2023. - New York, NY, USA : Association for Computing Machinery (ACM). ; , s. 11-20, s. 11-20
-
Conference paper (peer-reviewed)abstract
- With societies growing more and more conscious of human social biases that are implicit in most of our interactions, the development of automated robot social behavior is failing to address these issues as more than just an afterthought. In the present work, we describe how we unintentionally implemented robot listener behavior that was biased toward the gender of the participants, while following typical design procedures in the field. In a post-hoc analysis of data collected in a between-subject user study (n=60), we find that both a rule-based and a deep learning-based listener behavior models produced a higher number of backchannels (listener feedback, through nodding or vocal utterances) if the participant identified as a male. We investigate the cause of this bias in both models and discuss the implications of our findings. Further, we provide approaches that may be taken to address the issue of algorithmic fairness, and preventative measures to avoid the development of biased social robot behavior.

Research review (peer-reviewed)abstract
- Current research points to a large energy efficiency potential in industry which is still left unexploited. One of the most promising means of reducing energy consumption and related energy costs is implementing an energy management. This paper provides a systematic review of existing academic journal publications on energy management in industry. Five essential key elements of an energy management based on overarching themes are identified within the body of literature (strategy/planning, implementation/operation, controlling, organization and culture) and the specific findings relating to each key element are synthesized. Subsequently a conceptual framework of an energy management is developed which illustrates that a comprehensive approach is necessary in order to effectively exploit the existing energy efficiency potential. Finally implications for further research are described.

Self‐reported exercise‐induced dyspnea and airways obstruction assessed by oscillometry and spirometry in adolescents
- 2022
-
In: Pediatric Allergy and Immunology. - : John Wiley & Sons. - 0905-6157 .- 1399-3038. ; 33:1
-
Journal article (peer-reviewed)abstract
- Background Self-reported exercise-induced dyspnea (EID) is common among adolescents. Possible underlying pathologies are exercise-induced bronchoconstriction (EIB) and laryngeal obstruction (EILO). The forced oscillation technique (FOT) may evaluate exercise-induced changes in airway caliber. Aim To investigate in adolescents the relationship between EID, EIB (post-exercise fall in forced expiratory volume in 1s (FEV1)>= 10%), EILO, and post-exercise challenge changes in FOT parameters. Methods One hundred and forty-three subjects (97 with EID) of 13-15 years old underwent a standardized exercise challenge with FOT measurement and spirometry repeatedly performed between 2 and 30 min post-exercise. EILO was studied in a subset of 123 adolescents. Subjects showing greater changes than the healthy subgroup in the modulus of the inspiratory impedance were considered FOT responders. Results EID-nonEIB subjects presented similar post-exercise changes in all FOT parameters to nonEID-nonEIB adolescents. Changes in all FOT parameters correlated with FEV1 fall. 45 of 97 EID subjects responded neither by FEV1 nor FOT to exercise. 19 and 18 subjects responded only by FEV1 (onlyFEV(1)responders) or FOT (onlyFOTresponders), respectively. Only a lower baseline forced vital capacity (FVC)%predicted and a higher FEV1/FVC distinguished the onlyFEV(1)responders from onlyFOTresponders. FOT parameters did not present specific post-exercise patterns in EILO subjects. Conclusion FOT can be used to identify post-exercise changes in lower airway function. However, EID has a modest relation with both FEV1 and FOT responses, highlighting the need for objective testing. More research is needed to understand whether onlyFEV(1)responders and onlyFOTresponders represent different endotypes.

High Li+ and Na+ Conductivity in New Hybrid Solid Electrolytes based on the Porous MIL-121 Metal Organic Framework
- 2021

Journal article (peer-reviewed)abstract
- Solid-state electrolytes (SSEs) can leapfrog the development of all-solid-state batteries (ASSBs), enabling them to power electric vehicles and to store renewable energy from intermittent sources. Here, a new hybrid Li+ and Na+ conducting SSE based on the MIL-121 metal-organic framework (MOF) structure is reported. Following synthesis and activation of the MOF, the free carboxylic units along the 1D pores are functionalized with Li+ or Na+ ions by ion exchange. Ion dynamics are investigated by broadband impedance spectroscopy and by Li-7 and Na-23 NMR spin-lattice relaxation. A crossover at 50 degrees C (Li+) and at 10 degrees C (Na+) from correlated to almost uncorrelated motion at higher temperature is observed, which is in line with Ngai's coupling model. Alternatively, in accordance to the jump relaxation model of Funke, at low temperature only a fraction of the jump processes are successful as lattice rearrangement in the direct vicinity of Li+ (Na+) is slow. H-1 NMR unambiguously shows that Li+ is the main charge carrier. Conductivities reach 0.1 mS cm(-1) (298 K, Na+) while the activation energies are 0.28 eV (Li+) and 0.36 eV (Na+). The findings pave the way towards development of easily tunable and rationally adjustable high-performance MOF-based hybrid SSEs for ASSBs.

Two- and three-pion quantum statistics correlations in Pb-Pb collisions at root S-NN=2.76 TeV at the CERN Large Hadron Collider
- 2014
-
In: Physical Review C (Nuclear Physics). - 0556-2813. ; 89:2
-
Journal article (peer-reviewed)abstract
- Correlations induced by quantum statistics are sensitive to the spatiotemporal extent as well as dynamics of particle-emitting sources in heavy-ion collisions. In addition, such correlations can be used to search for the presence of a coherent component of pion production. Two- and three-pion correlations of same and mixed charge are measured at low relative momentum to estimate the coherent fraction of charged pions in Pb-Pb collisions at root S-NN = 2.76 TeV at the CERN Large Hadron Collider with ALICE. The genuine three-pion quantum statistics correlation is found to be suppressed relative to the two-pion correlation based on the assumption of fully chaotic pion emission. The suppression is observed to decrease with triplet momentum. The observed suppression at low triplet momentum may correspond to a coherent fraction in charged-pion emission of 23% +/- 8%.

In: Contemporary Challenges in Autoimmunity. - : Wiley. - 0077-8923 .- 1749-6632. ; 1173, s. 675-682

Conference paper (peer-reviewed)abstract
- The objective of our study was to determine the prevalence of anti-infectious agent antibodies and autoantibodies in a unique non-Westernized population from Kitava, Papua New Guinea (PNG), compared to Western populations. We matched 120 serum samples from Kitavans with 437 samples from four healthy control groups. Sera were tested for the presence of anti-infectious agent antibodies (treponema, toxoplsmosis, Epstein-Barr virus, cytomegalovirus, rubella) and autoantiobodies [anti-double-stranded (ds)DNA, anti-chromatin, anti-ribonucleoprotein (RNP), anti-SSB, anti-SSA, anti-Scl-70, anti-Smith, anti-centromer, anti-SmRNP, anti-Jo-1, and anti-ribosomal-P] using the Bio-Rad BioPlex 2200. Antitreponemal antibodies were detected in 87% of PNG sera versus 0-6% of controls (P < 0.0001). Anti-dsDNA antibodies were detected in 31% of PNG samples, which was significantly higher than in three of the control groups (<10%). The outstanding high rate of antitreponemal antibodies detected in Kitavans possibly represents prior yaws disease. A low prevalence of cardiovascular disease was previously documented in Kitavans and has been attributed, in addition to their diet, to the high prevalence of natural cardioprotective autoantibodies (the IgM-antiphosphorylcholine antibodies) in this population. Treponemal infection has been shown to induce the appearance of antiphosphorylcholine antibodies. These protective autoantibodies may cross-react with the pathogenic anti-dsDNA antibodies. Thus, it is suggested that infection with treponema is associated with the presence of protective as well as pathogenic autoantibodies.

Characterization Factors to Assess Land Use Impacts on Pollinator Abundance in Life Cycle Assessment
- 2023
-
In: Environmental Science and Technology. - : American Chemical Society (ACS). - 0013-936X .- 1520-5851. ; 57:8, s. 3445-3454

Journal article (peer-reviewed)abstract
- While wild pollinators play a key role in global food production, their assessment is currently missing from the most commonly used environmental impact assessment method, Life Cycle Assessment (LCA). This is mainly due to constraints in data availability and compatibility with LCA inventories. To target this gap, relative pollinator abundance estimates were obtained with the use of a Delphi assessment, during which 25 experts, covering 16 nationalities and 45 countries of expertise, provided scores for low, typical, and high expected abundance associated with 24 land use categories. Based on these estimates, this study presents a set of globally generic characterization factors (CFs) that allows translating land use into relative impacts to wild pollinator abundance. The associated uncertainty of the CFs is presented along with an illustrative case to demonstrate the applicability in LCA studies. The CFs based on estimates that reached consensus during the Delphi assessment are recommended as readily applicable and allow key differences among land use types to be distinguished. The resulting CFs are proposed as the first step for incorporating pollinator impacts in LCA studies, exemplifying the use of expert elicitation methods as a useful tool to fill data gaps that constrain the characterization of key environmental impacts.

A combined comparative and phylogenetic analysis of the Chapacuran language family
- 2016
-
In: International Journal of American Linguistics. - 0020-7071 .- 1545-7001. ; 82:3, s. 255-284
-
Journal article (peer-reviewed)abstract
- The Chapacuran language family, with three extant members and nine historically attested lects, has yet to be classified following modern standards in historical linguistics. This paper presents an internal classification of these languages by combining both the traditional comparative method (CM) and Bayesian phylogenetic inference (BPI). We identify multiple systematic sound correspondences and 285 cognate sets of basic vocabulary using the available documentation. These allow us to reconstruct a large portion of the Proto-Chapacuran phonemic inventory and identify tentative major subgroupings. The cognate sets form the input for the BPI analysis, which uses a stochastic Continuous-Time Markov Chain to model the change of these cognate sets over time. We test various models of lexical substitution and evolutionary clocks, and use ethnohistorical information and data collection dates to calibrate the resulting trees. The CM and BPI analyses produce largely congruent results, suggesting a division of the family into three different clades.

Journal article (peer-reviewed)abstract
- We developed a robotic system that can behave in an emotional way. A 3-wheeled simple robot with limited degrees of freedom was designed. Our goal was to make the robot displaying emotions in music performance by performing expressive movements. These movements have been compiled and programmed based on literature about emotion in music, musicians’ movements in expressive performances, and object shapes that convey different emotional intentions. The emotions happiness, anger, and sadness have been implemented in this way. General results from behavioral experiments show that emotional intentions can be synthesized, displayed and communicated by an artificial creature, also in constrained circumstances.

Journal article (other academic/artistic)abstract
- Texten inleder en artikeltriad i detta nummer om utvecklingen av det svenska integritetsskyddet under det senaste halvseklet. De tre bidragen tar sin utgångspunkt i ett jubileumsseminarium som hölls till Stig Strömholms ära hösten 2021, där ämnet diskuterades ur flera olika rättsliga perspektiv. I denna text står skadeståndsrätten i fokus. Skadeståndsrättsliga förstärkningar av integritetsskyddet har ofta utmanats och debatterats, men under senare år har ett flertal förändringar ändå skett med ett starkare skydd som följd. I texten kopplas dessa förändringar till dels Strömholms insatser på området, dels den inverkan som de samhälleliga fenomenen digitalisering och globalisering fått på juridiken.

Following international trends while subject to past traditions : neuropsychological test use in the Nordic countries
- 2016
-
In: Clinical Neuropsychologist (Neuropsychology, Development and Cognition. - : Informa UK Limited. - 1385-4046 .- 1744-4144. ; 30, s. 1479-1500
-
Journal article (peer-reviewed)abstract
- Objective: Historically, the neuropsychological test traditions of the four Nordic countries have spanned from the flexible and qualitative tradition of Luria-Christensen to the quantitative large battery approach of Halstead and Klove-Matthews. This study reports current test use and discusses whether these traditions still influence attitudes toward test use and choice of tests. Method: The study is based on survey data from 702 Nordic neuropsychologists. Results: The average participant used 9 tests in a standard assessment, and 25 tests overall in their practice. Test use was moderated by nationality, competence level, practice profile, and by attitude toward test selection. Participants who chose their tests flexibly used fewer tests than those adhering to the flexible battery approach, but had fewer tests from which to choose. Testing patients with psychiatric disorders was associated with using more tests. IQ, memory, attention, and executive function were the domains with the largest utilization rate, while tests of motor, visual/spatial, and language were used by few. There is a lack of academic achievement tests. Screening tests played a minor role in specialized assessments, and symptom validity tests were seldom applied on a standard basis. Most tests were of Anglo-American origin. Conclusions: New test methods are implemented rapidly in the Nordic countries, but test selection is also characterized by the dominating position of established and much researched tests. The Halstead-Reitan and Luria traditions are currently weak, but national differences in size of test batteries seem to be influenced by these longstanding traditions.
