Optimization and electrical control of photovoltaic (PV) and proton exchange membrane (PEM) electrolyzer systems are critical for efficient, scalable hydrogen production. Static coupling methods employ fixed electrical interconnections between PV arrays and the PEM stack, which cannot adapt to fluctuating irradiance or temperature. To overcome this, we propose an adaptive reconfiguration optimizat

Invariant natural killer T 1 (iNKT1) cells are prototypic interferon γ-producing, innate-like T lymphocytes that play crucial roles in protection against pathogen infection and cancer. In the thymus, where these cells develop, iNKT cells contribute to the recruitment of antigen-presenting cells and promote T cell tolerance. Although the transcriptional programs guiding iNKT cell specification are

Nanoparticle properties depend strongly on composition, making precise control essential for applications in catalysis, sensing, and electronics. By combining two or more elements in a single particle, synergistic properties can emerge that are inaccessible to the individual constituents. Realising these benefits, however, requires reliable methods for tuning composition at the nanoscale.This thes

BACKGROUND/AIM: Determining the causation of an injury in living individuals is a key task for forensic pathologists. However, little is known about sex-based differences in injury characteristics. The study aims to examine sex-based differences in single stab injuries to the trunk among assault survivors, to potentially identify injury patterns that could aid forensic assessment and help in the m

Despite extensive cataloging of carcinogenic exposures by the International Agency for Research on Cancer (IARC) and pharmacogenomic variation by resources such as PharmVar and CPIC, few platforms unify exposure, metabolic activation and detoxification, DNA damage, and genetic annotation within a single interactive visualization framework. This gap limits systematic evaluation of gene-environment

The success of cell therapy for type 1 diabetes (T1D) depends on reliable differentiation of stem cells into functional pancreatic islets. Current protocols produce stem cell-derived islets (SC-islets) that contain non-endocrine cells and show limited maturity. We developed a robust protocol that generates functional SC-islets from all eight tested human pluripotent stem cell (hPSC) lines. Differe

A computational method to simulate bimolecular quenching reactions using coarse-grained reaction-diffusion dynamics is presented and applied to the quenching of molecular photosensitizers in solution. The simulations describe photoinduced reactions involving explicit excited states of light-harvesting species together with intrinsic deactivation, as well as collision quenching from separate quench

AbstractThe need to minimise wear of hardmetal cutting tool materials requires an understanding of, and in turn accurate measurement of, both the external changes in dimensions and the internal microstructural changes which cause plastic deformation underneath the tool coating.This paper summarises development of methods to quantify the dimensional changes of the complex 3D tip shape of a tool and

Synthetic biomaterials used as bone graft extenders (BGE) in spinal fusion surgery can supplement but do not replace autologous bone. This pilot study evaluated a calcium sulfate/hydroxyapatite (CaS/HA) material as an antibiotic-eluting BGE and a carrier for bone morphogenetic protein-2 (BMP-2) in a rabbit posterolateral lumbar (L4–L5) spinal fusion model (PLF). Pre-set CaS/HA beads were loaded wi

Wetlands are often constructed to counteract eutrophication or brownification of downstream waters, although our understanding of their differences in efficiency and effects is still scarce. Therefore, we here used the upper and lower 95% confidence limits of the average retention capacity of 11 wetlands to represent efficient and inefficient wetlands, respectively. We then modelled future scenari

Background: Violent Crime Convicted Persons (VCCPs) are at increased risk of somatic health problems over the life course. However, the topic remains insufficiently studied, particularly regarding interactions with healthcare services in high-risk groups over extended periods. This prospective study aimed to explore adverse somatic outcomes in young adult VCCPs with a history of imprisonment and t

The nomadic pastoralists of the Sahel are often identified as a group at the frontline of global climate change. Their existence in arid and semi-arid regions and their reliance on seasonal rainfall are among the factors that contribute to their vulnerability to drought and climate shocks. This study focuses on risks to pastoralists in Sudan, asking whether index-based livestock insurance, an innoPastoralism is a nomadic lifestyle and a livelihood system that revolves around raising livestock. By migrating seasonally in search of water and pasture for their animals, pastoralists are able to inhabit and make productive use some of the world’s harshest environments. In Sudan, where over 90% of the vast land area is covered by desert and drylands, pastoralism remains a vital feature of the co

To assess presence of virus DNA in skin lesions, swab samples from 82 squamous cell carcinomas of the skin (SCCs), 60 actinic keratoses (AKs), paraffin-embedded biopsies from 28 SCCs and 72 kerathoacanthomas (KAs) and fresh-frozen biopsies from 92 KAs, 85 SCCs and 92 AKs were analyzed by high throughput sequencing (HTS) using 454 or Ion Torrent technology. We found total of 4,284 viral reads, out

Arterial stiffness reflects the ageing processes in the vascular system, and studies have shown an association between reduced cognitive function and cerebral small vessel disease. Small vessel disease can be visualized as white matter hyperintensities (WMH) and lacunar infarcts but also as cerebral microbleeds on brain magnetic resonance imaging (MRI). We aimed to investigate if arterial stiffnes

BACKGROUND: To explore the level of physical activity in a population based sample of older adults; to analyze the influence of pain characteristics and fear-avoidance beliefs as predictors of physical activity among older adults reporting chronic pain. METHODS: Demographics, pain characteristics (duration, intensity), physical activity, kinesiophobia (excessive fear of movement/(re) injury), se

Background: In experimental studies, the apolipoprotein D (APOD) and the sigma receptor type 1 (SIGMAR1) have been related to processes of brain damage, repair and plasticity. Methods: We examined blood samples from 3081 ischemic stroke (IS) patients and 1595 control subjects regarding 10 single nucleotide polymorphisms (SNPs) in the APOD (chromosomal location 3q29) and SIGMAR1 (chromosomal locati
