Nanophotonic enhanced perovskite-silicon solar cell devices

Perovskite-silicon tandem solar cells are a promising concept for overcoming the limits of conventional silicon single-junction technology. Light management is doubtless a key issue for further boosting efficiency. We discuss the impact of photonic nanostructures on the optical performance of perovskite-silicon devices. We experimentally and numerically demonstrate shallow antireflective nanotextu

Corporate social responsibility and employer brand personality appeal : approaches for human resources challenges in the hospitality sector

Employer branding in organizational human resources management is essential. Nevertheless, certain gaps persist within the realm of scientific research in this field, particularly in the exploration of novel concepts like employer brand personality appeal and its potential impact within the hospitality industry, which grapples with numerous human resources challenges. To fill this gap in knowledge

Neighborhood green spaces and use of social services in an older urban population

With an aging population, an increased burden is put on national and regional healthcare and social systems. In Sweden, municipalities are required to provide inhabitants with the social services needed to enable them to live an independent life in their own home for as long as possible. Urban green spaces (UGS) may increase physical activity and social interaction, as well as improve wellbeing an

A Multicenter Observational Study Evaluating Outcomes Associated With Antibiotic Combination Versus Monotherapy in Patients With Septic Shock

Objectives: To explore the association between antibiotic combination therapy and in-hospital mortality in patients with septic shock in two tertiary ICUs in different countries. Design: Retrospective observational study. Setting: ICUs of two tertiary hospitals, Royal Brisbane and Women's Hospital, Brisbane, QLD, Australia, and Rigshospitalet, Copenhagen, Denmark. Patients: Adult patients with ant

Consensus criteria for chronic rhinosinusitis disease control : an international Delphi Study*

Background: Chronic rhinosinusitis (CRS) disease control is a global metric of disease status for CRS. While there is broad acceptance that it is an important treatment goal, there has been inconsistency in the criteria used to define CRS control. The objective of this study was to identify and develop consensus around essential criteria for assessment of CRS disease control. Methods: Modified Del

Human factors and factor of the human : Pilot performance and pilot mental health

Human factors (HF) is a cross-disciplinary field of science that is strongly associated with safety, especially in regards to the role of human performance in ensuring safe actions and outcomes. Although ‘cross-disciplinary' in this context represents the admirable aim to use all available knowledge to enhance safety, even the field of human factors has to outline the limitations of itself as a fi

MISSION, MONEY, AND POWER

The term “mission” in its modern meaning was coined during the expansion of Western Christianity which was in many ways entangled with colonialism. The Western missionary movement’s modus operandi was adopted by missions from other backgrounds as well, when economic growth and growth of revivalist Christianity have coincided. When the outcome is new churches in economically underprivileged areas,

Renal Hyperparathyroidism

Renal hyperparathyroidism (rHPT) is a complex and challenging disorder. It develops early in renal failure, mainly as a consequence of reduced levels of vitamin D, hypocalcemia, diminished excretion of phosphate, and inability to activate vitamin D. RHPT is associated with increased risk of fractures, cardiovascular disease and death. The diagnosis of rHPT rests on demonstrating elevated levels of

High intensity perturbations induce an abrupt shift in soil microbial state

Soil microbial communities play a pivotal role in regulating ecosystem functioning. But they are increasingly being shaped by human-induced environmental change, including intense “pulse” perturbations, such as droughts, which are predicted to increase in frequency and intensity with climate change. While it is known that soil microbial communities are sensitive to such perturbations and that effe

Solar photospheric spectrum microvariability : I. Theoretical searches for proxies of radial-velocity jittering

Context. Extreme precision radial-velocity spectrometers enable extreme precision in stellar spectroscopy. Searches for low-mass exoplanets around solar-type stars are limited by various types of physical variability in stellar spectra, such as the short-term jittering of apparent radial velocities on levels of ∼2 m s-1. Aims. To understand the physical origins of radial-velocity jittering, the so

Evidence of Site-Specific and Male-Biased Germline Mutation Rate in a Wild Songbird

Germline mutations are the ultimate source of genetic variation and the raw material for organismal evolution. Despite their significance, the frequency and genomic locations of mutations, as well as potential sex bias, are yet to be widely investigated in most species. To address these gaps, we conducted whole-genome sequencing of 12 great reed warblers (Acrocephalus arundinaceus) in a pedigree s

Staten och maten - kan skatter och subventioner rädda liv?

Kostintaget i Sverige följer inte Livsmedelsverkets rekommendationer. I den här studien undersöker vi om skatter och subventioner på livsmedel kan påverka människors matvanor och hälsa. Vi studerar skatter på produkter med hög andel mättade fetter och på produkter med hög andel salt, och hur de är relaterade till dödsfall från kostrelaterade sjukdomar. Vi undersöker även i vilken utsträckning subv

A decade of maize yield gap studies in sub-Saharan Africa: how are farm-level factors considered?

The study of yield gaps has become more complex, prompting the use of varied approaches to measure yields and a wider range of factors to explain these gaps. In the Global North, the focus is on precision farming, whereas in sub-Saharan Africa (SSA), a broader perspective is necessary due to pronounced variability in farmland conditions. While biogeophysical and management factors have been tradit

Interface reduction technique for Enhanced Craig-Bampton method

Substructure coupling and model order reduction using Component Mode Synthesis (CMS) have, over recent years, gained considerable attention in the vibroacoustic analysis of complex structures. In the CMS methodology, the interior dynamics of each subcomponent in a substructured system are represented by a truncated set of normal modes within the lower frequency range, while all physical degrees of

A Fecal Metabolite Signature of Impaired Fasting Glucose : Results From Two Independent Population-Based Cohorts

Prediabetes is a metabolic condition associated with gut mi-crobiome composition, although mechanisms remain elu-sive. We searched for fecal metabolites, a readout of gut microbiome function, associated with impaired fasting glucose (IFG) in 142 individuals with IFG and 1,105 healthy individuals from the UK Adult Twin Registry (TwinsUK). We used the Cooperative Health Research in the Region of Aug

Dose-response analysis of protracted absorbed organ dose and site-specific cancer incidence in Sweden after the Chernobyl nuclear power plant accident

Background: Adult males in Sweden exhibit an increased risk of cancer associated with an increased absorbed dose to the colon from the Chernobyl accident. Methods: A closed cohort, with information on hunter status, included all individuals living in northern Sweden in 1986. Complete annual information on exposure to 137Cs at the dwelling coordinate was available for a total of 2,104,101 individua
