Perovskite‐Based Catalysts for the Oxygen Evolution Reaction: Synthesis, Device Relevant Performance, and Scale‐Up Strategies

ABSTRACT Perovskite‐based oxides are promising electrocatalysts for the oxygen evolution reaction due to their flexible composition, tunable electronic structure, and robust nature. However, their activity and durability in proton exchange membrane (PEM)–relevant acidic condition...

Efficient Calculation of Absorption Spectra of Platinum Complexes Used as Luminescent Probes for Cancer Detection

Despite major advances in oncology, many chemotherapeutic agents still cause severe side effects that reduce quality of life, motivating new approaches for early detection and targeted elimination of cancer cells. Luminescent transition metal complexes are promising biomolecular...

Longitudinal progression, metrics, age-dependence, and modifiers of ataxia severity in SCA27B: a multicentre study of 219 patients

Background Spinocerebellar Ataxia 27B (SCA27B) is a novel, frequent and likely treatable late-onset autosomal-dominant ataxia caused by GAA repeat-expansions in FGF14 . For understanding disease evolution and imminent trial planning, metrics of the most widely used clinical outco...

AI-generated food stimuli match real counterparts in perceived healthiness and calorie content but not in realism or willingness to eat

Abstract Visual food stimuli are widely used in food perception and evaluation research, but are often limited by a lack of control of confounding variables. AI-generated food images may be a viable but yet understudied alternative. In a within-subject online experiment, 87 parti...

CX3CR1 Modulates Migration of Resident Microglia Towards Cortical Laser‐Induced Lesions

Microglia are innate immune cells of the central nervous system (CNS). They extend their processes and migrate toward injuries in vivo. However, how the fractalkine receptor (CX3CR1) influences microglial migration remains unknown. Label-free proteomic profiling predicted changes...

eDNA metabarcoding provides scalable and continuous biodiversity monitoring across the tree of life

Abstract Environmental DNA (eDNA) metabarcoding has the potential to substantially expand our knowledge of global biodiversity beyond that provided by conventional approaches. However, the degree to which eDNA data provides real ecological insight, rather than primarily reflectin...

Assessing the Systematic and Random Error From a Single Snapshot in Stochastic Homogenization of Industrial Scale Composites

ABSTRACT We estimate effective linear elastic properties from a single microstructure image using a sliding‐window subsampling strategy applied to fields obtained by computational micromechanics. The method yields both mean properties and variance estimates without requiring mult...

A Methodology for Early User Experience Evaluation of Large-Scale Collaborative Robot Applications

When implementing collaborative robot applications, it is paramount to use a human-centered development approach to ensure a positive user experience and increase acceptance. User Experience (UX) design methods involve validating user experience through evaluations as a basic pri...

Outcome after cataract surgery with IOL implantation in adolescents and adults with juvenile idiopathic arthritis (JIA) associated or ANA-positive anterior uveitis

Purpose Cataract surgery in patients with chronic anterior uveitis may be associated with increased risk for complications and poor outcomes. This study analyses visual outcome, uveitis course and complications after cataract surgery with intraocular lens (IOL) implantation in ad...

Damage Transport with Redistribution

This work is concerned with Damage Transport (DT), a framework for continuum damage mechanics that provides softening damage models while ensuring mathematically well-posed boundary value problems. DT was constructed in a two-step process: First, the cross-convex envelope of the...

Data-driven mapping of known and novel fluid biomarker progression profiles in genetic frontotemporal lobar degeneration

Abstract Introduction Recent proteomic studies have identified both established and novel proteins in genetic frontotemporal lobar degeneration (FTLD). However, it remains unclear at what point in the disease these proteins deviate from normal levels and how their trajectories re...

Uncertainty-Aware Bayesian Machine Learning for Thermo-Kinetic Parameter Estimation from Noisy Temperature Profiles

Temperature–time profiles obtained through thermistor-based monitoring provide a rich but noise-sensitive source of information for estimating kinetic and thermal parameters in exothermic batch reactions. Conventional workflows typically combine deterministic smoothing with numer...

Transmission diffuse EUV scattering by nanoscale Lamb waves in thin membranes

We report time-resolved diffuse extreme ultraviolet (EUV) scattering measurements of optically excited acoustic waves in thin Ti/SiN bilayers in transmission geometry. Following femtosecond optical excitation, the EUV diffuse scattering signal yields circular fringe patterns evol...

How Personal and Cognitive Traits Influence AI Attitudes, Ethics, and Well-being: The Role of AI Autonomy and Criticality in Design

Abstract As artificial intelligence (AI) systems become increasingly prevalent in decision-making, it’s essential to understand public perceptions in various contexts and cultures for responsible use. This study examines the relationship between acceptance and fear of AI, conside...

Wanted? The Elusiveness of (Post-)Growth in Anthropocene Research

Abstract There is now wide agreement that the Earth has entered a new geological epoch as a result of human activities, which is often encapsulated in the concept of the “Anthropocene.” Meanwhile, there remains considerable debate about the impact of economic growth on planetary...

Mental Health Disorders, Suicide Attempts, Substance Use, and Substance Use Disorders in Adults with Fetal Alcohol Spectrum Disorders: A Gender-Separated Study

Abstract Fetal alcohol spectrum disorders (FASD) are a group of neurodevelopmental disorders caused by alcohol exposure during pregnancy. FASD is associated with various neurocognitive disorders over the entire lifespan. Comorbid mental health disorders seem to be highly prevalen...

Diagnostic Value of Multiplane Tool in Virtual Lesion Confirmation in Augmented Fluoroscopy-Guided Navigational Bronchoscopy for Peripheral Pulmonary Lesions

BACKGROUND: The demand for minimally invasive diagnostic techniques for peripheral pulmonary lesions (PPL) is rising. Augmented fluoroscopy (AF) provides real-time guidance by overlaying CT-derived virtual targets onto fluoroscopic images, yet its diagnostic value remains poorly...

Legal Struggles Between Managerialism and Authoritarianism: Contesting European Supply Chain Regulation

Abstract Legal struggles unfold when conflicts enter the legal arena and are processed within the framework of the legal form. Traditionally, such battles require a framework in which the pillars of the rule of law guarantee the interpretation and implementation of laws enacted t...
