A number of virtual reality head-mounted displays (HMDs) with integrated eye trackers have recently become commercially available. If their eye tracking latency is low and reliable enough for gaze-contingent rendering, this may open up many interesting opportunities for researchers. We measured eye tracking latencies for the Fove-0, the Varjo VR-1, and the High Tech Computer Corporation (HTC) Vive
Transfusion-related acute lung injury (TRALI) is a hazardous transfusion complication with an associated mortality of 5% to 15%. We previously showed that stored (5 days) but not fresh platelets (1 day) cause TRALI via ceramide-mediated endothelial barrier dysfunction. As biological ceramides are hydrophobic, extracellular vesicles (EVs) may be required to shuttle these sphingolipids from platelet
The C-terminal-fragments of alpha1-antitrypsin (AAT) have been identified and their diverse biological roles have been reported in vitro and in vivo. These findings prompted us to develop a monoclonal antibody that specifically recognizes C-36 peptide (corresponding to residues 359–394) resulting from the protease-associated cleavage of AAT. The C-36-targeting mouse mono-clonal Immunoglobulin M (I
School refusal (SR) can have several negative consequences, but effective treatments are available. When chronic, school absence requires comprehensive treatment. This study evaluates an intervention for SR based on a Cognitive Behavioral Therapy (CBT) model, Hemmasittarprogrammet (HSP). Attendance, anxiety, depression, quality of life, and emotional and behavioral symptoms were measured at pre-tr
An important challenge in the design and implementation of self-optimizing systems is that of finding a model that maps changes in a tunable parameter (or “knob”) into an effect on the performance, power, or energy, of the overall system. This paper describes ARPE (Analyzing the Relationship between Parameters and Effectors), an open source tool to analyze the effect of parameter changes on the be
Background and Aims: There are increasing reports on case series on spontaneous isolated mesenteric artery dissection, that is, dissections of the superior mesenteric artery and celiac artery, mainly due to improved diagnostic capacity of high-resolution computed tomography angiography performed around the clock. A few case–control studies are now available, while randomized controlled trials are
Extracellular matrix (ECM) is a dynamic 3-dimensional network of macromolecules that provides structural support for the cells and tissues. Accumulated knowledge clearly demonstrated over the last decade that ECM plays key regulatory roles since it orchestrates cell signaling, functions, properties and morphology. Extracellularly secreted as well as cell-bound factors are among the major members o
We study the long-term impact of a policy-driven change in childhood nutrition. For this purpose, we evaluate a program that rolled out nutritious school lunches free of charge to all pupils in Swedish primary schools between 1959 and 1969. We estimate the impact of the program on children's economic, educational, and health outcomes throughout life. Our results show that the school lunch program
Background: Presently, 1 in 4 Lebanese adolescents is involved in bullying, with 12% being perpetrators. In Lebanon, around 90% of bullying incidents occur in schools. Given the lack of studies tackling bullying perpetration in Lebanon, this study aims to identify and target risk factors of bullying perpetration among Lebanese adolescents, which would serve future prevention and intervention progr
Inflammatory airway diseases and lower respiratory tract infections are leading causes of severe illness, disability and death worldwide. Much of today´s hypotheses about the underlying inflammatory processes and pathogenic contribution by immune cells come from in vitro experiments or animal models. As a consequence, our knowledge of the actual immunopathological events in real patient tissues is
Commensality (the act of eating together) is studied in a range of disciplines and often considered important for social communion, order, health and well-being, while simultaneously being understood as in decline (especially the family meal). However, such claims are also contested in various ways. In this paper, we discuss the expanding field of commensality research and critically reflect on th
Objective To understand and report on the impact of the COVID-19 pandemic on the everyday lives of frail older persons living in nursing homes by exploring their experiences of how the pandemic-related restrictions had influenced them and in what way. Design Empirical qualitative interview study. Setting A publicly run nursing home in an urban area in Sweden in June 2020. The nursing home had visi
This study aimed to investigate the responses of university students (late adolescents) about their conceptualization of a child, exploring the characteristics they associate with being a child. The study was conducted in two phases. In phase 1, responses to one open-ended question, what is a child? (N=75), were analyzed using qualitative content analysis. In phase 2, students (N=90) filled in an
In this paper we highlight the presence of tachycardia in Post-acute Covid-19 Syndrome by introducing a new label for this phenomenon: Post-covid-19 tachycardia syndrome and argue that this constitutes a phenotype or sub-syndrome in PACS. We also discuss epidemiology, putative mechanisms, treatment options and future research directions in this novel clinical syndrome.
The use of coarse-grain reconfigurable architectures (CGRA) is a suitable alternative for hardware acceleration in many application areas, including digital holographic imaging. In this paper, we propose a CGRA-based system with an array of processing and memory cells, which communicate using a local and a global communication network, and a stream memory controller to manage data transfers to ext
Popular Abstract in Undetermined Denne afhandling præsenterer en ny udlæsnings metode udviklet til cantileverbaserede sensorer. Cantilevere er tynde vipper, der er fastgjorte i den ene ende, og som igennem de seneste ti °ar har vist sig at være en interessant ny type bio/kemisk sensor. Den specifikke genkendelse af et kemikalie viser sig ved at cantileveren bøjer som følge af det skabte overfladesThis thesis presents a novel read-out method developed for cantilever-based sensors. Cantilevers are thin beams clamped at one end and during the last 10 years they have emerged as an interesting new type of bio/chemical sensor. The specific recognition of a chemical manifests itself as a bending of the cantilever from the generated surface stress. Conventionally the read-out used for this type of
A silica substituted alpha phase tricalcium phosphate was developed by way of solid state reaction. The difference in reactivity of two different production methods using isothermal calorimetry and X- ray diffraction was also recorded. It was suggested that a silica substituted alpha phase tricalcium phosphate can be produced and characterized by way of X-ray measurement. Referencing selected sign
