Observation of the Multilayer Growth Mode in Ternary InGaAs Nanowires
Au-seeded semiconductor nanowires have classically been considered to only grow in a layer-by-layer growth mode, where individual layers nucleate and grow one at a time with an incubation step in between. Recent in situ investigations have shown that there are circumstances where binary semiconductor nanowires grow in a multilayer fashion, creating a stack of incomplete layers at the interface bet
Risk factors for knee osteoarthritis after traumatic knee injury : A systematic review and meta-analysis of randomised controlled trials and cohort studies for the OPTIKNEE Consensus
Objective: To identify and quantify potential risk factors for osteoarthritis (OA) following traumatic knee injury. Design: Systematic review and meta-analyses that estimated the odds of OA for individual risk factors assessed in more than four studies using random-effects models. Remaining risk factors underwent semiquantitative synthesis. The modified GRADE (Grading of Recommendations Assessment
Clinical, economic, and health-related quality of life burden associated with von Willebrand disease in adults and children : Systematic and targeted literature reviews
Introduction: Debilitating clinical complications in von Willebrand disease (VWD) can affect health-related quality of life (HRQoL), increase healthcare costs and cause long-lasting consequences. However, the magnitude of these burdens needs to be more fully explored. Aim: To estimate the prevalence and burden of clinical complications, the impact on HRQoL and the economic burden associated with V
Revisiting the growth rate hypothesis : Towards a holistic stoichiometric understanding of growth
The growth rate hypothesis (GRH) posits that variation in organismal stoichiometry (C:P and N:P ratios) is driven by growth-dependent allocation of P to ribosomal RNA. The GRH has found broad but not uniform support in studies across diverse biota and habitats. We synthesise information on how and why the tripartite growth-RNA-P relationship predicted by the GRH may be uncoupled and outline paths
Vascular Aging and COVID-19
Vascular age is determined by functional and structural changes in the arterial wall. When measured by its proxy, pulse wave velocity, it has been shown to predict cardiovascular and total mortality. Disconcordance between chronological and vascular age might represent better or worse vascular health. Cell senescence is caused by oxidative stress and sustained cell replication. Senescent cells acq
Analysis of High-Performing Terahertz Quantum Cascade Lasers
Detailed simulations for terahertz quantum cascade lasers based on two-well designs are presented. We reproduce the maximal operation temperatures observed and attribute the degradation with temperature to the occupation of parasitic levels and thermal backfilling. Furthermore, we demonstrate that the current injection can be conveniently studied by using states, which combine energy selectivity a
Magnetic resonance and diffusion tensor imaging of the adolescent rabbit growth plate of the knee
Purpose: To assess the ability of MRI-DTI to evaluate growth plate morphology and activity compared with that of histomorphometry and micro-CT in rabbits. Methods: The hind limbs of female rabbits aged 16, 20, and 24 wk (n = 4 per age group) were studied using a 9.4T MRI scanner with a multi-gradient echo 3D sequence and DTI in 14 directions (b-value = 984 s/mm2). After MRI, the right and left hin
Imaging in gynecological disease (24) : clinical and ultrasound characteristics of ovarian mature cystic teratomas
Objective: To describe the clinical and ultrasound features of ovarian mature cystic teratomas (MCTs). Methods: This was a retrospective study. From the International Ovarian Tumor Analysis (IOTA) database, we identified patients with a histologically confirmed diagnosis of MCT who had undergone transvaginal ultrasound examination between 1999 and 2016 (IOTA phases 1, 2, 3 and 5) in one of five ce
Reversible Self-Assembled Monolayers with Tunable Surface Dynamics for Controlling Cell Adhesion Behavior
Cells adhering onto surfaces sense and respond to chemical and physical surface features. The control over cell adhesion behavior influences cell migration, proliferation, and differentiation, which are important considerations in biomaterial design for cell culture, tissue engineering, and regenerative medicine. Here, we report on a supramolecular-based approach to prepare reversible self-assembl
Mechanisms to control laser-plasma coupling in laser wakefield electron acceleration
Experimental results, supported by precise modeling, demonstrate optimization of a plasma-based injector with intermediate laser pulse energy (
A quantitative synthesis of and predictive framework for studying winter warming effects in reptiles
Increases in temperature related to global warming have important implications for organismal fitness. For ectotherms inhabiting temperate regions, ‘winter warming’ is likely to be a key source of the thermal variation experienced in future years. Studies focusing on the active season predict largely positive responses to warming in the reptiles; however, overlooking potentially deleterious conseq
Design opportunities for future development of crisis communication technologies for marginalised groups – Co-designing with Swedish disability organisations
Purpose: The purpose is to firstly, provide an example of how voices of people with various disabilities (motor, visual, hearing, and neuropsychiatric impairments) can be listened to and involved in the initial phases of a co-design process (Discover, Define). Secondly, to present the outcome of the joint explorations as design opportunities pointing out directions for future development of crisis
Experimental and theoretical near-edge x-ray-absorption fine-structure studies of NO+
Experimental near-edge x-ray-absorption fine-structure (NEXAFS) spectra of the nitrosonium NO+ ion are presented and theoretically analyzed. While neutral NO has an open shell, the cation is a closed-shell species, which for NEXAFS leads to the simplicity of a closed-shell spectrum. Compared to neutral NO, the electrons in the cation experience a stronger Coulomb potential, which introduces a shif
Intensification of heat transfer behind the backward-facing step using tabs
The influence of tab size and location on the flow structure, distribution of pressures on the surface, and heat transfer in the separation region behind the backward-facing step at Reynolds number Re = 4000 was experimentally investigated. The effect of tabs on the distribution of the local pressure and heat transfer coefficients in the longitudinal and transversal directions was studied. The pre
Methodology and parameters to analyse daylighting and energy use in dense cities: A literature review
Low energy buildings are key to reduce global energy use. However, achieving low energy use and good daylight levels simultaneously in dense cities is challenging. This article reviews relevant studies dealing with energy use and daylighting in dense residential urban blocks located in Nordic climates. The literature review combines a systematic and a ‘snowball’ search approach. Findings indicate
Expansion of the Inguinal Adipose Tissue Depot Correlates With Systemic Insulin Resistance in C57BL/6J Mice
To accommodate surplus energy, the adipose tissue expands by increasing adipocyte size (hypertrophy) and number (hyperplasia). The presence of hypertrophic adipocytes is a key characteristic of adipose tissue dysfunction. High-fat diet (HFD) fed C57BL/6J mice are a commonly used model to study obesity and obesity-related complications. In the present study, we have characterized adipose plasticity
