Structure of an antennally-expressed carboxylesterase suggests lepidopteran odorant degrading enzymes are broadly tuned
Insects rely on the detection of chemical cues present in the environment to guide their foraging and reproductive behaviour. As such, insects have evolved a sophisticated chemical processing system in their antennae comprised of several types of olfactory proteins. Of these proteins, odorant degrading enzymes are responsible for metabolising the chemical cues within the antennae, thereby maintain
Migrating Young Unaccompanied Children and the Mobile Commons : Law, Vulnerability, and the Practice of Family Reunification in Sweden
In this article I call for an awareness of the mobile commons– the informal support that exists among migrating people, NGOs, and activists – in relation to the realization of family reunification. Taking its point of departure in a concrete case of family reunification for young unaccompanied children, the article seeks to expose how the traditional legal notion of the liberal subject fails to pr

Dual antiplatelet Use for extended period taRgeted to AcuTe ischemic stroke with presumed atherosclerotic OrigiN (DURATION) trial : Rationale and design
Rationale: The optimal duration of dual antiplatelet therapy (DAPT) with clopidogrel-aspirin for the large artery atherosclerotic (LAA) stroke subtype has been debated. Aims: To determine whether the 1-year risk of recurrent vascular events could be reduced by a longer duration of DAPT in patients with the LAA stroke subtype. Methods and study design: A total of 4806 participants will be recruited
Tuning of Quasi-Vertical GaN FinFETs Fabricated on SiC Substrates
In this work, we present the fabrication and investigation of the properties of quasi-vertical gallium nitride (GaN) fin field effect transistors (FinFETs) on silicon carbide (SiC) substrates and the influence of a postgate metallization annealing (PMA). The devices reveal low subthreshold swings (SSs) down to around 70 mV/dec. For a 1- $\mu \text{m}$ -thick drift layer, a low ON-resistance below
Iron Photoredox Catalysis-Past, Present, and Future
Photoredox catalysis of organic reactions driven by iron has attracted substantial attention throughout recent years, due to potential environmental and economic benefits. In this Perspective, three major strategies were identified that have been employed to date to achieve reactivities comparable to the successful noble metal photoredox catalysis: (1) Direct replacement of a noble metal center by
An exploratory modelling study of chemiluminescence in ammonia-fuelled flames. Part 2
The detailed kinetic mechanism of the author was extended by reactions describing formation and consumption of excited species which are formed in NH3+CH4+air flames, complementing the modelling efforts presented in Part 1. Currently the model includes the following excited species: O(1D), OH*, O2*, CH*, CH2(1), NO2*, NO(A), NH*, N2(A), NH2*, C2*, CO2*, CH2O*, and CN*, among which many were observ
The Role of Scientific Language Use and Achievement Level in Student Sensemaking
Many science students struggle with using scientific language and making sense of scientific phenomena. Thus, there is an increased interest in science education research and public policy with regard to understanding and promoting scientific language use and sensemaking in science classrooms. However, there is a lack of comparative studies on how upper-secondary school students of different achie
Accuracy of uncalibrated 2D digital subtraction angiography measurements on a novel biplane system compared to computed tomography angiography
Background: 2D digital subtraction angiography (DSA) images are the gold standard for neuroradiological vascular assessment and the basis of interventional procedures such as mechanical thrombectomy and cerebral aneurysm coiling. However, length measurements in projected DSA images are affected by the distance between the x-ray source, the object, and the detector. Precise coordination between all
Arts and culture engagement and mortality : A population-based prospective cohort study
Aims: The aim of this study was to investigate associations between having visited the theatre/cinema and an arts exhibition during the past year and all-cause, cardiovascular disease (CVD), cancer and other-cause mortality. Methods: The 2008 public health postal survey in Scania, Sweden, was distributed to a stratified random sample of the adult population (18–80 years old). The participation rat
Randomized clinical Trial Comparing drug Eluting Stent Zilver PTX® Versus Bare Metal Stent Zilver Flex® for Treatment of Lesions in Femoral and Popliteal Arteries in Chronic Limb Threatening Ischemia
Objective: Drug eluting stents (DES) might improve the results of stenting in the femoropopliteal (FP) segment, but randomized data between DES and BMS in the treatment of patients with chronic limb threatening ischemia (CLTI) is lacking. The aim of this study was to perform a randomized comparison, between DES and bare metal stent (BMS) implantation in a subgroup of CLTI patients with lesions in
Parallel matters : Efficient polyp segmentation with parallel structured feature augmentation modules
The large variations of polyp sizes and shapes and the close resemblances of polyps to their surroundings call for features with long-range information in rich scales and strong discrimination. This article proposes two parallel structured modules for building those features. One is the Transformer Inception module (TI) which applies Transformers with different reception fields in parallel to inpu

Plasma phosphorylated tau 217 in preclinical Alzheimer's disease
An accurate blood test for Alzheimer's disease that is sensitive to preclinical proteinopathy and cognitive decline has clear implications for early detection and secondary prevention. We assessed the performance of plasma phosphorylated tau 217 (pTau217) against brain PET markers of amyloid [[11C]-labelled Pittsburgh compound B (PiB)] and tau ([18F]MK-6240) and its utility for predicting longitud
Do gender norms travel within corporations? The impact of foreign subsidiaries on the home country’s gender wage gap
In this note we study how the share of workers in a corporation located in a high gender wage gap country impacts the wage gap in their home country operations. Our findings support the hypothesis that firms with strong intra-firm linkages to a high gender wage gap country also display a relatively large gender wage gap at home.
