The vapor–liquid–solid (VLS) mechanism is probably the most versatile method to fabricate semiconductor nanowires and several investigations assume a compositionally homogeneous catalyst particle. In this investigation we address the compositional homogeneity of the catalyst particle during growth of nanowires. Using diffusion calculations, we show that the particle is indeed homogeneous during VL
Background: Medical devices are increasingly being reported to cause contact allergic dermatitis reactions. Objective: Review of patients with diabetes type I referred for suspected allergic contact dermatitis to insulin pump or glucose sensor systems. Method: We have reviewed 11 referred diabetes mellitus patients investigated for allergic contact dermatitis reactions to medical devices and speci
Background The increasing prevalence of atrial fibrillation and novel therapeutic tools to prevent cardioembolic stroke has increased the need for risk markers. Objectives This study explored the relationship between the midregional sequence of pro-atrial natriuretic peptide (MR-proANP) levels with the risk of atrial fibrillation and stroke, and whether measurement of MR-proANP improves the predic
A search is presented for new resonances decaying to a W or Z boson and a Higgs boson in the ℓ+ℓ−bb¯, ℓνbb¯, and νν¯bb¯ channels in pp collisions at s=13 TeV with the ATLAS detector at the Large Hadron Collider using a total integrated luminosity of 3.2 fb−1. The search is conducted by looking for a localized excess in the WH/ZH invariant or transverse mass distribution. No significant excess is o
A search for supersymmetry involving the pair production of gluinos decaying via third-generation squarks to the lightest neutralino (χ10) is reported. It uses an LHC proton-proton data set at a center-of-mass energy s=13 TeV with an integrated luminosity of 3.2 fb-1 collected with the ATLAS detector in 2015. The signal is searched for in events containing several energetic jets, of which at least
Cutaneous Leishmaniasis (CL) is an endemic vector-borne disease in the Middle East and a worldwide public health problem. The spread of CL is highly associated with the socio-ecological interactions of vectors, hosts and the environment. The heterogeneity of these interactions has hindered CL modeling for healthcare preventive measures in endemic areas. In this study, an agent-based model (ABM) is
Nanowires (NWs) have unique electrical and optical properties of value for many applications including lighting, sensing, and energy harnessing. Consumer products containing NWs increase the risk of NWs being released in the environment, especially into aquatic ecosystems through sewage systems. Daphnia magna is a common, cosmopolitan freshwater organism sensitive to toxicity tests and represents
This study explores the application of spatial modelling techniques to generate susceptibility maps for a neglected zoonotic disease, visceral leishmaniasis (VL), in an endemic area in southern Caucasus that includes Iran, Armenia and Azerbaijan. The social and physical environment of southern Caucasus has been mainly characterized by the presence of several factors that are strongly associated wi
The authors develop a methodology to create databases that can be used to add micro-level geographic context to longitudinal historical demographic analyses. The method transforms geographic objects as snapshots (digitized from historical maps) into temporal representations of longitudinal object lifelines and links individuals to these geographic objects. The methodology is evaluated via a case s

Review https://doi.org/10.1038/s41586-018-0087-1 New approaches for brain repair—from rescue to reprogramming Roger A. Barker1*, Magdalena Götz2,3* & Malin Parmar4* The ability to repair or promote regeneration within the adult human brain has been envisioned for decades. Until recently, such efforts mainly involved delivery of growth factors and cell transplants designed to rescue or replace a sp

In this study, we have analyzed the spatial and temporal correlation between the North Atlantic Oscillation (NAO) and the climate in Iraq, with a focus on precipitation, temperature, and number of Mediterranean cyclones. It was found that the influence of the NAO varies per climate indicator. For example, the influence is greater on precipitation than on temperature. One conclusion of the study is
BACKGROUND: The coronavirus disease 19 (COVID-19) pandemic has spread globally, causing extensive illness and mortality. In advance of effective antiviral therapies, countries have applied different public health strategies to control spread and manage healthcare need. Sweden has taken a unique approach of not implementing strict closures, instead urging personal responsibility. We analyze the res
Shibanqiao Reservoir (0.24 km(2)) and Xiaohe Reservoir (0.28 km(2)) have catchments of 6.00 km(2) and 22.69 km(2), respectively. They essentially represent "strongly eroded" (Shibanqiao) and "mildly eroded" (Xiaohe) regions in Guizhou Plateau, southwestern China. Sediment cores were retrieved from the two reservoirs and soils were also sampled from their catchments. Mineral magnetic measurements w
The aim of this study was to investigate from the perspective of formal carers the care given to people aged 65 and over, who are cared for in their own homes by informal care. Thirty-three district nurses (DNs) and 20 home service assistants in a municipality with 13500 inhabitants (over 65 years old), were interviewed about the location of care recipients and 398 care recipients were located. Mo
Background: Type 1 von Willebrand disease (VWD) is a congenital bleeding disorder characterized by a partial quantitative deficiency of plasma von Willebrand factor (VWF) in the absence of structural and/or functional VWF defects. Accurate assessment of the quantity and quality of plasma VWF is difficult but is a prerequisite for correct classification. Objective: To evaluate the proportion of mis
Popular Abstract in Swedish Under de senaste åren har nödvändigheten att ta hänsyn till utsatta grupper i den svenska befolkningen och deras varierande behov lyfts fram i rapporter och utredningar om utformningen av vård och rehabilitering av äldre. En sådan utsatt grupp är äldre teckenspråkliga döva. Svårigheten att kommunicera, i kombination med åldersrelaterade sjukdomar, funktionsbegränsningarVery little is known about the consequences of aging and the wellbeing of deaf sign language users. This thesis contributes to filling this knowledge gap. The overarching aim was to gain further understanding and to increase the knowledge about quality of life, in terms of subjective wellbeing and health, activity and social contacts, among older deaf sign language users. After having established
