Emergency department crowding and mortality in 14 Swedish emergency departments, a cohort study leveraging the Swedish Emergency Registry (SVAR)

Objectives There is evidence that emergency department (ED) crowding is associated with increased mortality, however large multicenter studies of high quality are scarce. In a prior study, we introduced a proxy-measure for crowding that was associated with increased mortality. The national registry SVAR enables us to study the association in a more heterogenous group of EDs with more recent data.

Exploring the Intrinsic Point Defects in Cesium Copper Halides

Cesium copper halides Cs3Cu2X5 (X = Cl, Br, and I) have attracted much attention for optoelectronic applications because of their self-trap excitons and high photoluminescence quantum yield. Intrinsic point defects play a critical role in the optoelectronic performance of these materials by affecting fundamental properties, such as carrier mobility, lifetime, and recombination rate. In this work,

Vertebral fracture : epidemiology, impact and use of DXA vertebral fracture assessment in fracture liaison services

Summary: Vertebral fractures are independent risk factors for vertebral and nonvertebral fractures. Since vertebral fractures are often missed, the relatively new introduction of vertebral fracture assessment (VFA) for imaging of the lateral spine during DXA-measurement of the spine and hips may contribute to detect vertebral fractures. We advocate performing a VFA in all patients with a recent fr

Phonon-Assisted Hot Carrier Generation in Plasmonic Semiconductor Systems

Plasmonic materials have optical cross sections that exceed by 10-fold their geometric sizes, making them uniquely suitable to convert light into electrical charges. Harvesting plasmon-generated hot carriers is of interest for the broad fields of photovoltaics and photocatalysis; however, their direct utilization is limited by their ultrafast thermalization in metals. To prolong the lifetime of ho

Genome-wide meta-analysis of muscle weakness identifies 15 susceptibility loci in older men and women

Low muscle strength is an important heritable indicator of poor health linked to morbidity and mortality in older people. In a genome-wide association study meta-analysis of 256,523 Europeans aged 60 years and over from 22 cohorts we identify 15 loci associated with muscle weakness (European Working Group on Sarcopenia in Older People definition: n = 48,596 cases, 18.9% of total), including 12 loc

Persistent Currents in Toroidal Dipolar Supersolids

We investigate the rotational properties of a dipolar Bose-Einstein condensate trapped in a toroidal geometry. Studying the ground states in the rotating frame and at fixed angular momenta, we observe that the condensate acts in distinctly different ways depending on whether it is in the superfluid or in the supersolid phase. We find that intriguingly, the toroidal dipolar condensate can support a

Optimization of Near-Surface Quantum Well Processing

Herein, an optimized process flow of near-surface quantum well metal–oxide–semiconductor field-effect transistors (MOSFETs) based on planar layers of metalorganic vapor-phase epitaxy (MOVPE) grown InxGa1−xAs is presented. It is found that by an optimized pre-growth cleaning and post-metal anneal, the quality of the MOS structure can be greatly enhanced. This optimization is a first step toward rea

Rational Design of Bright Long Fluorescence Lifetime Dyad Fluorophores for Single Molecule Imaging and Detection

Increasing demand for detecting single molecules in challenging environments has raised the bar for the fluorophores used. To achieve better resolution and/or contrast in fluorescence microscopy, it is now essential to use bright and stable dyes with tailored photophysical properties. While long fluorescence lifetime fluorophores offer many advantages in time-resolved imaging, their inherently low

Intraband dynamics and exciton trapping in the LH2 complex of Rhodopseudomonas acidophila

Over the last several decades, the light-harvesting protein complexes of purple bacteria have been among the most popular model systems for energy transport in excitonic systems in the weak and intermediate intermolecular coupling regime. Despite this extensive body of scientific work, significant questions regarding the excitonic states and the photo-induced dynamics remain. Here, we address the

On the solar air heater thermal enhancement and flow topology using differently shaped ribs combined with delta-winglet vortex generators

A numerical investigation has been conducted to study the convective heat transfer enhancement and friction loss behaviors for turbulent flow by using arrays of differently shaped ribs combined with delta-winglet vortex generators (DWVGs) pair on the absorber plate of a solar air heater. Four transverse vortex generators arrays, i.e., 90° continuous ribs, 90° truncated ribs, 60° V-shaped continuou

Performance investigation on the novel anti-leakage and easy-to-manufacture trisection helical baffle electric heaters

The difficult manufacturing of helical baffles hinders the widespread application of the enhancement technology and the shortcut leakage between adjacent baffles impairs the enhancement effects. To solve these two issues, the promising anti-leakage and easy-to-manufacture helical baffles with small inclined angle and folded structure are proposed, which can be produced by 2D laser cutting and simp

Application of infrared radiation in the drying of food products

Background: Drying is an important method to preserve food products. Although many traditional drying technologies (hot air, freeze, microwave drying) have been applied successfully to various food products, each drying technique has its own advantages and disadvantages. Novel drying methods such as infrared drying, have become very popular. Scope and approach: This study gives an overview on the

A novel pipe structure for geyser elimination in a vertical cryogenic pipe

In the present study, according to the recirculation concept, a new elimination structure for the geyser in a cryogenic pipe is proposed. An eccentric spacer plate is used to stimulate the recirculation inside the cryogenic pipe. The geyser-elimination effect of the proposed structure is then validated and the elimination physics is explored. It is found that the geyser is successfully eliminated

Epitaxial stabilization of thin films of the frustrated Ge-based spinels

Frustrated magnets can host numerous exotic many-body quantum and topological phenomena. GeNi2O4 is a three-dimensional S=1 frustrated magnet with an unusual two-stage transition to the two-dimensional antiferromagnetic ground state, while GeCu2O4 is a high-pressure phase with a strongly tetragonally elongated spinel structure and magnetic lattice formed by S=1/2 CuO2 linear chains with frustrated

UL25 capsid binding facilitates mechanical maturation of the Herpesvirus capsid and allows retention of pressurized DNA

The maturation process that occurs in most viruses is evolutionarily driven as it resolves several conflicting virion assembly requirements. During herpesvirus assembly in a host cell nucleus, micron-long double-stranded herpes DNA is packaged into a nanometer-sized procapsid. This leads to strong confinement of the viral genome with resulting tens of atmospheres of intra-capsid DNA pressure. Yet,

Gold and cobalt oxide nanoparticles modified poly‐propylene poly‐ethylene glycol membranes in poly (E‐caprolactone) conduits enhance nerve regeneration in the sciatic nerve of healthy rats

Reconstruction of nerve defects is a clinical challenge. Autologous nerve grafts as the gold standard treatment may result in an incomplete restoration of extremity function. Biosynthetic nerve conduits are studied widely, but still have limitations. Here, we reconstructed a 10 mm sciatic nerve defect in healthy rats and analyzed nerve regeneration in poly (ɛ‐caprolactone) (PCL) conduits longitudi

PURPOSE: The aim of the study was to determine the perimetric rate of glaucoma progression in the ongoing Glaucoma Intensive Treatment Study (GITS) after 3 years of follow-up.DESIGN: This is a randomized, two-centre, prospective open-labelled treatment trial for open-angle glaucoma (OAG).PARTICIPANTS: The participants of this study were treatment-naive patients with newly diagnosed OAG, aged 46-78

Experimental investigation on the thermo-hydraulic characteristics and occurrence boundary of geyser in a cryogenic pipe

In the present study the thermo-hydraulic characteristics of geyser in the cryogenic fuel transportation pipe of a liquid rocket is experimentally investigated using liquid nitrogen. The typical thermo-hydraulic appearances are characterized and analyzed in the geyser process to effectively recognize the occurrence of geyser in practical engineering. The effect of interfering factors such as heat

Inflammatory markers are associated with quality of life, physical activity, and gait speed but not sarcopenia in aged men (40–79 years)

Background: Age-related chronic low-grade inflammation (inflammaging) is one of the proposed mechanisms behind sarcopenia. However, findings regarding inflammatory markers in sarcopenic older adults are conflicting. This study aimed to determine the association between inflammatory markers, prevalent as well as incident sarcopenia, sarcopenia-defining parameters, quality of life (QoL), and physica
