Light-emitting diodes (LEDs) have been investigated during the past decades, for which a major challenge is total internal reflection that limits the light extraction efficiency. ‘Nanotree’ LEDs elegantly solve this bottleneck. Lower band gap nanowire branches are grown on higher band gap core wires. Charge carriers diffuse into the branches and recombine there. Total internal reflection is impede

We present processed light emitting diodes (LED) devices based on GaInP core-branch nanowire (NW) structures. The LEDs rely on the charge carrier diffusion induced light emitting diode concept. The GaInP core has a higher Ga content than the branches to induce diffusion of carriers from the cores into the branches. The branches play the role of the active region in the structure, where charge carr

The recent discovery of well-preserved fragments of Sphenothallus in the Central Clare Group (Pennsylvanian) of western Ireland provides new insights into the morphology of this enigmatic, putative cnidarian. The specimens demonstrate a morphological plasticity, including features not previously described for Sphenothallus, such as the presence of flat sides and angular lateral margins, non-bilate

The in-flow focusing method, introduced herein, enables rapid and straightforward measurements of the whole-channel acoustic energy of acoustic flow-through devices. The method is applied to assess the whole-channel acoustic energy and acoustophoretic efficiency frequency spectra of a bottom-actuated silicon-glass and a side-actuated glass chip. The input variables are the time-independent geometr

Introduction: Proteomic analysis of injured human peripheral nerves, particularly focusing on events occurring in the proximal and distal nerve ends, remains relatively underexplored. This study aimed to investigate the molecular patterns underlying a digital nerve injury, focusing on differences in protein expression between the proximal and distal nerve ends. Methods: A total of 26 human injured

This article traces publishing patterns in the Swedish humanities between 1840 and 1880; a period characterized by a new publishing regime yet bridging two dominant publication forms, the dissertation, and the disciplinary journal. Using the prominent historian Wilhelm Erik Svedelius as an entry point, the article charts how scholars in the humanities navigated the publishing landscape in a more d

A range of charge-stabilized aqueous polyurethane (PU) dispersions comprising hard segments formed from hydrogenated methylene diphenyl diisocyanate (H12MDI) with dimethylolpropionic acid (DMPA) and ethylenediamine, and soft segments of poly(tetramethylene oxide) of different molecular weights are synthesized. Characterization of the dispersions by mass spectrometry, gel permeation chromatogr

Background: A substantial proportion of individuals with COPD have never smoked, and it is implied to be more common than previously anticipated but poorly studied. Aim: To describe the process of recruitment of never-smokers with COPD from a population-based cohort (n = 30 154). Methods: We recruited never-smokers with COPD, aged 50–75 years, from six University Hospitals, based on: 1) post bronc

The European Union has committed to achieving climate neutrality by the year 2050, with Sweden setting an even more ambitious target of reaching this milestone by 2045. A subgroup comprising 23 pioneering Swedish municipalities, collectively representing 40% of the country's population, aims to attain climate neutrality by 2030. Globally, buildings and construction sector contribute nearly 40% of

This paper analyses three governments’ institutional advisory mechanisms designed to shape and support universities and individual researchers’ decisions regarding international academic collaboration. Although ostensibly country-agnostic, increasing geopolitical tensions with China have catalyzed the creation of these new structures. Each mechanism seeks to address the complex trade-offs in inter

This explorative literature review aims to examine the content and methodologies of recent empirical studies on the aspirations of youth in situations of migration in Europe. The search yielded 30 peer-reviewed social science publications in English for the period 2010–2022, including both intra-European migrants ages 10–24 and youth with backgrounds from outside Europe. Contextual analysis was us

The existence and significance of endogenous cytosolic and nuclear mono-ADP-ribosylation has been a matter of debate. Today, evidence suggests that the human enzymes that catalyze the reaction have been rounded up. Moreover, substrate proteins and specific functions for mono-ADP-ribosyltransferases are beginning to be defined. Reader domains that specifically recognize mono-ADP-ribosylated target

a choir for people with experience of being infertility treatment .LYTTEKOR is an artistic research project for individuals with experiences of fertility treatment. We work creatively with listening, voice, and body in a confidential and caring space.Our approach is based on vocal compositions inspired by Deep Listening (a method developed by Pauline Oliveros). Through listening, we open up to greater self-acceptance, understanding of our situation, and shared ex

Researchers have envisioned and pioneered data-driven programming assistance for developers based on their interaction with the tools via multiple sensors such as eye trackers, microphones, and AI. However, these new sensors gather sensitive data from programmers, to what extent users can accept them and in what form they may work well are largely unclear. Meanwhile, developer tools such as static

Background: Urinary tract infection (UTI) in infants is a common, potentially life-threatening bacterial infection, and must be managed carefully through the entire chain of care from diagnosis, choice of treatment, follow-up and risk stratification of future complications. This Swedish nationwide study of infant UTI was conducted to evaluate the current management of infant UTI, yield of investig
