Radiation efficiencies of modal current densities distributed on a spherical shell are evaluated in terms of dissipation factor. The presented approach is rigorous, yet simple and straightforward, leading to closed-form expressions. The same approach is utilized for a two-layered shell and the results are compared with other models existing in the literature. Discrepancies in this comparison are r
Polarized neutron reflectometry is used to determine the sequence of magnetic switching in interlayer exchange coupled Fe/MgO(001) superlattices in an applied magnetic field. For 19.6 Å thick MgO layers we obtain a 90 periodic magnetic alignment between adjacent Fe layers at remanence. In an increasing applied field the top layer switches first followed by its second-nearest neighbor. For 16.4 Å M
Objective: The significantly higher incidence rates of microscopic colitis (MC) in Denmark compared to Sweden remains unexplained. Methods: Consecutive patients with newly diagnosed MC in the neighbouring regions of Skåne in 2011–2015 and Zealand in 2010–2016 were prospectively identified. Data on large bowel endoscopies and biopsies rates were retrieved. Information on putative factors were obtai
Identifying the metabolites associated with alcohol consumption may provide insights into the metabolic pathways through which alcohol may affect human health. We studied associations of alcohol consumption with circulating concentrations of 123 metabolites among 2974 healthy participants from the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Alcohol consumption at rec
Underreporting of road crashes hampers the development of appropriate road safety countermeasures in many countries. In this study, police and hospital records from road crash casualties in the Melaka Tengah district in Malaysia from 2014 were collected to determine their matching and reporting rates. Based on authentic personal identifiers from both types of records, Microsoft SQL was used to rev
BACKGROUND: A key component of achieving universal health coverage is ensuring that all populations have access to quality health care. Examining where gains have occurred or progress has faltered across and within countries is crucial to guiding decisions and strategies for future improvement. We used the Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016) to assess person

An experimental and analytical method has been applied to evaluate air flow pattern in three main kinds of Iranian traditional wind catchers. Results indicate that ARDAKANI wind catcher with one opening is not an efficient device, and airflow average rate in its shaft is negative. It means that one-side wind catcher has a high rate air extract specially in summer and spring which air supply is dem
Single-phase niobium is used in superconducting accelerator components in particle accelerating facilities. Functionality of such accelerator components is placing high demands on the surface quality. Single-phase niobium, as opposed to niobium alloys, is a highly ductile metal, which in a cutting process normally leads to such surface defects as adhesion, built-up edges, side flow, and burr forma
Breast and gynecologic cancers harboring PIK3CA mutations showed no significant responses to AZD5363, a pan-AKT catalytic inhibitor, in contrast with previous in vitro data showing activity of the drug in this subset of cancers. These results raise the question of how to select the most accurate predictive biomarkers of response.
The dramatic increase in breast cancer incidence compels a paradigm shift in our preventive efforts. There are several barriers to overcome before prevention becomes an established part of breast cancer management. The objective of this review is to identify the clinical challenges for improved breast cancer prevention and discuss current knowledge on breast cancer risk assessment methods, risk co
Implementation of minority rights norms is an important step for integration. The ultimate aim of norm diffusion is internalization, that is, when a norm is being taken for granted. This article seeks to develop an understanding of socialization beyond formal compliance and suggests that material and ideational structures at both the elite and societal levels mutually reinforce one another. The fr
In this issue of Blood, Prince et al report that by targeting anticoagulant protein S (PS), they could achieve hemostasis and prevent hemarthrosis in murine models of hemophilia.1
