Optimum operating conditions of a fuel cell will provide its maximum efficiency and the operating cost will be minimized. Thus, operation optimization of the fuel cell is essential. Neural networks can simulate systems without using simplifying assumptions. Therefore, the neural network can be used to simulate complex systems. This paper investigates the effects of important parameters, i.e., temp

A continuous integrated bioprocess available from the earliest stages of process development allows for an easier, more efficient and faster development and characterization of an integrated process as well as production of small-scale drug candidates. The process presented in this article is a proof-of-concept of a continuous end-to-end monoclonal antibody production platform at a very small scal

We apply the Atkinson (1970) inequality index to time series of asset returns to offer a novel measure of financial risk consistent with expected-utility theory. This measure is converted to a certainty-equivalent return serving as a performance measure. We extend the Atkinson index to HARA utility and derive closed-form solutions to our measures for a number of preference-return combinations. Fur

In recent years, increasing inlet temperature of gas turbines has far exceeded the melting point of the metal materials. Film cooling technology has widely been used to protect gas turbine blades from erosion of the high-temperature gases. The film cooling performance can be improved by optimization of the hole configurations. Results show that the backward injection hole has a smaller exit moment

Background: Since long travel times to reach health facilities are associated with worse outcomes, geographic accessibility is one of the six core global surgery indicators; this corresponds to the second of the “Three Delays Framework,” namely “delay in reaching a health facility.” Most attempts to estimate this indicator have been based on geographical information systems (GIS) algorithms. The a

The elliptic flow (v2) of (anti-)3He is measured in Pb–Pb collisions at sNN=5.02TeV in the transverse-momentum (pT) range of 2–6 GeV/c for the centrality classes 0–20%, 20–40%, and 40–60% using the event-plane method. This measurement is compared to that of pions, kaons, and protons at the same center-of-mass energy. A clear mass ordering is observed at low pT, as expected from relativistic hydrod

We evaluated the joint associations between a new 313-variant PRS (PRS313) and questionnaire-based breast cancer risk factors for women of European ancestry, using 72,284 cases and 80,354 controls from the Breast Cancer Association Consortium. Interactions were evaluated using standard logistic regression, and a newly developed case-only method, for breast cancer risk overall and by estrogen recep

Within rheumatology, telehealth is essential to modern rehabilitation due to the demographic development with more and more elderly people. At present, telehealth solutions are used as part of the rehabilitation process in assessment, interventions and evaluation. Telehealth interventions are as effective as conventional follow-ups or self-management assessments, but the evidence on the effect is

Nigeria has the highest number of AIDS-related deaths in the world. In this study, we characterised the HIV-1 molecular epidemiology by analysing 1442 HIV-1 pol sequences collected 1999-2014 from four geopolitical zones in Nigeria using state-of-the-art maximum-likelihood and Bayesian phylogenetic analyses. The main circulating forms were the circulating recombinant form (CRF) 02_AG (44% of the an

Autonomous vehicle functions in safety-critical situations show promise in reducing the risk and saving lives in accidents compared to existing safety systems. Consequently, it is from many perspectives advantageous to be able to quantify the potential benefits of new autonomous systems for vehicle maneuvers at-the-limit of tire friction. Here, to estimate the potential in terms of saved lives and

We perform theoretical calculations to reproduce the site-selective X-ray emission spectroscopy (XES) spectrum for carbonate and bicarbonate ions in aqueous solution at the oxygen K-edge. We perform structure sampling, and using an ab initio molecular dynamics simulation, we reproduce the solute-solvent model. Relative XES peak intensities with core-hole excited state molecular dynamics simulation

High-resolution O 1s resonant inelastic x-ray scattering spectra of liquid H2O, D2O, and HDO, obtained by excitation near the preedge resonance show, in the elastic line region, well-separated multiple vibrational structures corresponding to the internal OH stretch vibration in the ground state of water. The energy of the first-order vibrational excitation is strongly blueshifted with respect to t

Palaearctic steppes evolved under the Cenozoic cold arid climate and megaherbivore pressure. A large portion of the biome persisted into the Holocene but has recently been subjected to human land use alternation. Pseudophilotes bavius (Lepidoptera: Lycaenidae) is a steppe specialist sporadically distributed in Eastern Europe and Pontic-Caspian region (from Transylvania to Southern Urals), the Balk

Design variables in density-based topology optimization are typically regularized using filtering techniques. In many cases, such as stress optimization, where details at the boundaries are crucially important, the filtering in the vicinity of the design domain boundary needs special attention. One well-known technique, often referred to as “padding,” is to extend the design domain with extra laye

Cigarette smoking is a risk factor for osteoporosis and bone fracture. Moreover, smoking causes exposure to cadmium, which is a known risk factor for osteoporosis. It is hypothesized that part of smoking-induced osteoporosis may be mediated via cadmium from tobacco smoke. We investigated this hypothesis using mediation analysis in a Swedish cohort of elderly men. This study was performed in 886 el

Purpose: Predicting the visual gain from cataract surgery when the main cause of vision loss is age-related macular degeneration may be difficult and warrants the need for an objective predictor of subjective outcome. Full-field electroretinography is an objective measure of overall retinal function. We therefore wanted to study if full-field electroretinography can predict subjective visual outco

Red Cell Distribution Width (RDW) could be a risk factor for developing various chronic diseases, and seems to be a prognostic marker in patients with cardiovascular disease (CVD) or cancer. Our aim was to explore the association between RDW and all-cause and cause-specific mortality in a general population. RDW was measured in 27,063 participants (aged 45-73 years) from the population-based Malmö
