Progress in the power conversion efficiency of solar cells based on metal-halide perovskite semiconductors has been astonishing for the past years. During their development, transient effects have been observed that gave rise to an uncertainty associated with the determination of device performance from current density-voltage (J-V) measurements. This effect becomes visible in a dependence of the

In the wake of global crises concerning, for example, inequalities, migration, pandemics, and the environment, ethical concerns have come to the fore. In this thematic issue, we are especially interested in the role that the planning, design, and materialities of the built environment can take in relation to ethics, and we present four different openings or themes into urban ethics that we also th

This article aims to understand how the introduction of blue-green solutions affects ethical concerns and expectations of an urban environment. Blue-green solutions are complementary technical solutions, introduced into urban water management, in order to deal with the impact of urbanisation and climate change. These kinds of solutions establish new affordances that have an impact on everyday life

INTRODUCTION: The pituitary gland has a high expression of somatostatin receptors (SSTRs) and is therefore a potential organ at risk for radiation-induced toxicity after 177Lu-DOTATATE treatment.OBJECTIVE: To study changes in pituitary function in patients with neuroendocrine tumors (NETs) treated with dosimetry-based 177Lu-DOTATATE to detect possible late toxicity.METHODS: 68 patients from a phas

PURPOSE: Current hypothesis regarding the mechanism of active tear drainage is based on studies performed ex vivo or under nonphysiological conditions. Novel ultra-high-frequency ultrasound has the advantage of generating images with superior resolution, enabling measurements of low flow in small vessels, and the tracking of tissue motion in real time. The purpose of this study was to investigate

Introduction: Sclerostin, an inhibitor of bone formation, has emerged as a potential negative regulator of glucose homeostasis. We aimed to investigate if serum sclerostin associates with insulin sensitivity, beta cell function, prediabetes or metabolic syndrome in healthy men. Materials and methods: Serum sclerostin was measured in basal and insulin-stimulated samples from 526 men without diabete

The understanding of diesel sprays is very important to enable a better and cleaner marine engine design, but unfortunately little knowledge is openly available on marine engine fuel sprays. In this paper, evaporating sprays for medium speed marine engines were studied in a constant volume combustion chamber by performing optical measurements through Schlieren and Mie diagnostic techniques. The ef

Glyphosate (GLY), N-(phosphonomethyl) glycine, is the most widely used herbicide in the world. It is a broad-spectrum herbicide, also used in crop desiccation. Agricultural workers may be occupationally exposed and general populations may be exposed to GLY mainly through diet. We studied the kinetics of GLY by measuring the parent compound and its metabolite aminomethylphosphonic acid (AMPA) in ur

Collective intelligence (CI) is a form of distributed intelligence that emerges in collaborative problem solving and decision making. This work investigates the potentials of CI in demand side management (DSM) in urban areas. CI is used to control the energy performance of representative groups of buildings in Stockholm, aiming to increase the demand flexibility and climate resilience in the urban

Objective: To investigate if Cochrane reviews that assess screening interventions address their major harms. Study design and setting: A systematic search for Cochrane reviews that assess screening interventions was performed. Two authors independently screened abstracts, assessed full-texts, and extracted data from included reviews. For each review, two authors judged whether each predefined harm

Background: Biomarkers can be of help to understand critical illness and to identify and stratify sepsis. Adrenomedullin is a vasoactive hormone, with reported prognostic and potentially therapeutic value in sepsis. The primary aim of this study was to investigate the association of circulating bioactive adrenomedullin (bio-ADM) levels at intensive care unit (ICU) admission with mortality in sepsi

Context: Obesity and cardiometabolic diseases are associated with higher long-term glucocorticoid levels, measured as scalp hair cortisol (HairF) and cortisone (HairE). Cardiometabolic diseases have also been associated with copeptin, a stable surrogate marker for the arginine-vasopressin (AVP) system. Since AVP is, together with corticotropin-releasing hormone (CRH) an important regulator of the

Background: Personal recovery is associated with many significant health-related factors, but studies exploring associations between activity factors and personal recovery among service users are scarce. The aims of this study were hence to; 1) investigate if various aspects of activity may mediate change in recovery while also acknowledging clinical, sociodemographic and well-being factors; 2) ex

Frequency recognition algorithm for multiple exposures (FRAME) is a single-exposure imaging technique that can be used for ultrafast videography, achieved through rapid illumination with spatially modulated laser pulses. To date, both the limit in sequence length as well as the relation between sequence length and image quality are unknown for FRAME imaging. Investigating these questions requires

Fine-tuning of insulin release from pancreatic β-cells is essential to maintain blood glucose homeostasis. Here, we report that insulin secretion is regulated by a circular RNA containing the lariat sequence of the second intron of the insulin gene. Silencing of this intronic circular RNA in pancreatic islets leads to a decrease in the expression of key components of the secretory machinery of β-c

We introduce a family of boundary confinements for Coulomb gas ensembles, and study them in the two-dimensional determinantal case of random normal matrices. The family interpolates between the free boundary and hard edge cases, which have been well studied in various random matrix theories. The confinement can also be relaxed beyond the free boundary to produce ensembles with fuzzier boundaries,

Duplicative horizontal gene transfer may bring two previously separated homologous genes together, which may raise questions about the interplay between the gene products. One such gene pair is the “native” PgiC1 and “foreign” PgiC2 in the perennial grass Festuca ovina. Both PgiC1 and PgiC2 encode cytosolic phosphoglucose isomerase, a dimeric enzyme whose proper binding is functionally essential.

Background: Genome-wide association studies (GWAS) have proven successful in predicting genetic risk of disease using single-locus models; however, identifying single nucleotide polymorphism (SNP) interactions at the genome-wide scale is limited due to computational and statistical challenges. We addressed the computational burden encountered when detecting SNP interactions for survival analysis,
