Laterally grown InxGa1-xAs nanowires (NWs) are promising candidates for radio frequency and quantum computing applications, which, however, can require atomic scale surface and interface control. This is challenging to obtain, not least due to ambient air exposure between fabrication steps, which induces surface oxidation. The geometric and electronic surface structures of InxGa1-xAs NWs and conta
CONCLUSIONS: This update on the P1PK blood group system (Hellberg Å, Westman JS, Thuresson B, Olsson ML. P1PK: the blood group system that changed its name and expanded. Immunohematology 2013;29:25-33) provides recent findings concerning the P1PK blood group system that have both challenged and confirmed old theories. The glycosphingolipids can no longer be considered the sole carriers of the anti
We present the first one-step acoustic separation of high quality plasma and mononuclear cells (MNCs) from undiluted human whole blood. This enables centrifugation-free integration in analytical instrumentation.
Down to a cathodic potentials of -1.20 V versus the reversible hydrogen electrode, the structure of IrO2(110) electrodes supported by TiO2(110) is found to be stable by in situ synchrotron-based X-ray diffraction. Such high cathodic potentials should lead to reduction to metallic Ir (Pourbaix diagram). From the IrO2 lattice parameters, determined during cathodic polarization in a H2SO4 electrolyte
In this work, a fast and efficiently design method has been introduced. This design process consists of the overall design and the detailed design. For the overall design, one-dimensional pipe-network computations are employed to obtain several design cases quickly at the beginning. Meanwhile the solid domain geometry and mesh with cooling structures, i.e., film holes, impingement holes, and ribs
It is unclear whether caregiving has an impact on the physical, mental and functional health of older caregivers. This study aimed to describe physical, mental and functional health in relation to family caregiving in old age (60+) over a six-year period. The study comprised 2,294 randomly selected individuals (60–96 years) from the Swedish National Study on Aging and Care, who answered the questi
An international consensus on antineutrophil cytoplasm antibodies (ANCA) testing in eosinophilic granulomatosiswith polyangiitis (EGPA) is presented.ANCA, specific formyeloperoxidase (MPO), can be detected in 30-35% of patients with EGPA. MPO-ANCA should be tested with antigen-specific immunoassays in any patient with eosinophilic asthma and clinical features suggesting EGPA, including constitutio
Background: Distal radius fractures can adversely affect wrist function; for men with this fracture, the role played by fracture severity, age and osteoporosis on fracture outcome has not been sufficiently studied. Objective: To describe patient-reported outcome and the association with bone integrity, fracture severity and future fracture risk among young and older men with distal radius fracture
Osteoporosis-related fractures are undertreated, due in part to misinformation about recommended approaches to patient care and discrepancies among treatment guidelines. To help bridge this gap and improve patient outcomes, the American Society for Bone and Mineral Research assembled a multistakeholder coalition to develop clinical recommendations for the optimal prevention of secondary fractuream
The present status and development of strong-field nano-optics, an emerging field of nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is reached when the amplitude of the external electromagnetic fields that are driving a material approach or exceed the field strengths that bind the electrons inside the medium. In this strong-field regime, light-matter interact
Summary: In elderly ambulatory men, high platelet and high neutrophil counts are related to low bone mineral density (BMD), after adjustment for relevant covariates. Low hemoglobin (hgb) is even associated with low BMD, but this relationship seems to be dependent on estradiol and osteocalcin. Purpose: Blood and bone cells exist in close proximity to each other in the bone marrow. Accumulating evid
Study Objectives: To investigate relationships between sleep duration and adherence to healthy diets, but also associations with meal patterns, in a large population-based cohort. Methods: Participants (n = 23,829, males and females, aged 45 to 75 years) from the Swedish EpiHealth cohort study were included in a cross-sectional analysis. The participants filled out an extensive Internet-based ques
OBJECTIVES: Analyses performed by the Sarcopenia Definitions and Outcomes Consortium (SDOC) identified cut-points in several metrics of grip strength for consideration in a definition of sarcopenia. We describe the associations between the SDOC-identified metrics of low grip strength (absolute or standardized to body size/composition); low dual-energy x-ray absorptiometry (DXA) lean mass as previo
BACKGROUND: The Sarcopenia Definitions and Outcomes Consortium (SDOC) sought to identify cut points for muscle strength and body composition measures derived from dual-energy x-ray absorptiometry (DXA) that discriminate older adults with slow walking speed. This article presents the core analyses used to guide the SDOC position statements. DESIGN: Cross-sectional data analyses of pooled data. SETT
Droplet-based microfluidics is a widely used technology in various chemical and biological applications. Droplet formation is an essential part of droplet-based microfluidics. This work applied and summarized a combination of techniques for speeding up computational fluid dynamics (CFD) simulations based on the Volume of Fluid method for the droplet generation process. To demonstrate the efficienc
This work experimentally tests and numerically investigates the heat transfer augmentation, the flow characteristics and the overall thermal performance of truncated ribs in a rectangular channel with an aspect ratio of 1:4 designed by using the fractal theory. The liquid crystal thermography (LCT) method in steady-state is adopted and the three-dimensional CFD numerical simulations with an establ
The present work concentrates on perforated 90° ribs to improve the thermal performances in a rectangular cooling channel with an aspect ratio of 4:1. Three different types of perforated ribbed channels are designed and compared. Steady-state Liquid Crystal Thermography (LCT) is employed to measure surface temperature and derive heat transfer coefficients over the ribbed surfaces in the tested cha
Background: Will being a caregiver further impact the health of a group already at risk of adverse health due to old age? This study aimed to answer the questions whether short- and long-term healthcare consumption and mortality differ between informal caregivers and non-caregivers and between high-burden and low-burden informal caregivers. Method: The study population consisted of 423 caregivers
Commonly, heat transfer performance of a nanofluid is enhanced by increasing the mass fraction of nanoparticles due to an improvement of the thermo-physical properties. However, increasing the number of nanoparticles in the base fluid will result in an increase of the nanofluid viscosity. This research aims to investigate natural convective heat transfer for an electric heater filled with various
