Biomass Burning in Australia: No Evidence for Carbonyl Sulfide (OCS) Enhancement in Fire Plumes From In‐Situ Measurements During SouthTRAC

Abstract Determining the atmospheric abundance and the emission sources of carbonyl sulfide (OCS) plays a crucial role for the sulfur budget in the atmosphere. In addition to its main anthropogenic and biogenic sources, biomass burning is assumed to be an essential, but not well...

Observation of a supersolid phase in a spin-orbit coupled exciton-polariton Bose-Einstein condensate

In Bose-Einstein condensates, spin-orbit coupling (SOC) produces supersolidity. It is a peculiar state of matter, which, in addition to the superfluid behavior, shows periodic density modulation typical for crystals. Here, we report the fabrication of an original type of optical...

A Holistic Lifecycle-Oriented Analysis of High-Performance Lithium-Ion Batteries: Aging, Advanced Diagnostics, Thermal Management, and Digitalized Education

Lithium-ion batteries (LIBs) have become central to modern energy storage systems, yet their increasing material and electrochemical complexity introduces significant challenges across their entire lifecycle. During first-life operation, high-performance applications such as fast...

A Finite‐Strain Phase‐Field‐Regularized Elastoplastic Damage Model for Polypropylene

ABSTRACT A rotation‐free finite‐strain phase‐field‐regularized elastoplastic damage formulation is presented for the tensile failure simulation of polypropylene (PP). The bulk response is represented by a hyperelastic–isotropic–plastic material branch formulated in a corotated in...

Probing and Graph Coloring Techniques for Trace Estimation in Lattice QCD

ABSTRACT The computation of , where is the Wilson–Dirac matrix of Lattice QCD, is a fundamental and computationally demanding task with applications to disconnected hadronic correlation functions. Since is a dense matrix of prohibitive size, its trace cannot be computed exactly,...

Formative and Reflective Measurement Models in Workplace Learning Research: A Critical Review and Guidelines

ABSTRACT Quantitative empirical research in workplace learning regularly makes use of measurement instruments that operationalize theoretical constructs. However, in domains related to workplace learning, high levels of measurement model misspecifications—up to 62% of all cases—h...

Obesity is more strongly associated with physical performance and body composition than sarcopenia in patients with spondyloarthritis

Abstract Objectives Integrated data on body composition, objective physical performance and daily physical activity are limited in spondyloarthritis (SpA). The objective of this study is to describe DXA-derived body composition phenotypes and examine their cross-sectional associa...

What is it Like to Recover From Psychosis? An Interpretative Phenomenological Analysis

Abstract This study aims to explore the lived experience of recovery from psychosis, with a focus on pre-reflective, embodied, and intersubjective aspects. Semi-structured interviews were conducted with six individuals diagnosed with schizophrenia. The data collected were analyze...

Improved nanoparticle productivity via flat-top 49-beam nanosecond pulsed laser ablation in liquids

Abstract Pulsed laser ablation in liquids (PLAL) is a versatile and environmentally friendly technique for producing surfactant-free, high-purity nanoparticles (NPs) suitable for applications in catalysis and biomedicine. However, its industrial scalability is limited by low thro...

Mapping ESD-Related Beliefs Among Pre-Service Primary School Teachers: A Q-Methodological Approach

Teachers’ beliefs about Education for Sustainable Development (ESD) shape how they perceive and enact ESD as an educational task, yet remain empirically understudied, particularly among pre-service primary school teachers. This study investigates ESD-related belief patterns among...

Motion Anisotropy of Individual, Unconfined Rod-Like-Shaped Salmonella Typhimurium Bacteria

Abstract With the continuous advancement of microscopic imaging techniques, the motion of micro- and nanosized particles can be followed with increasing spatial and temporal accuracy. Analyzing the tracks of single particles enables one to address a broad range of scientific ques...

Oral health disparities and social determinants in Cameroon: a scoping review

Abstract Background Oral health disparities represent a major but under-prioritized public health challenge in Cameroon. Despite a growing burden of caries, periodontal disease, and tooth loss, oral health remains marginalized within national policy. Understanding the social dete...

A Peter–Weyl theorem for compact group bundles and the geometric representation of relatively ergodic compact extensions

We show that a relatively ergodic extension of measure-preserving dynamical systems has relative discrete spectrum if and only if it can be represented as a skew-product by a bundle of compact homogeneous spaces. Our result holds without restrictions on the acting group or the un...

Re-opening to the world: recovery and trust

Background There is a lack of research on the experience of environmental influences and atmospheres in the recovery process of persons diagnosed with schizophrenia. So far, phenomenological approaches have only rarely been applied to study the connection between environmental ef...

Motivation under pressure: a systematic review of psychological and organizational factors in emergency volunteering

Emergency services worldwide rely heavily on volunteers, yet high-risk organizations such as fire, civil protection, and disaster response services struggle with member demotivation and dropout. This systematic review integrates psychological and organizational perspectives to id...

Logarithmic prismatic cohomology, motivic sheaves, and comparison theorems

Abstract We prove that (logarithmic) prismatic and (logarithmic) syntomic cohomology are representable in the category of logarithmic motives. As an application, we obtain Gysin maps for prismatic and syntomic cohomology, and we explicitly identify their cofibers. We also prove a...

A high-density real-time 1024-pixel terahertz near-field imager in 130-nm SiGe BiCMOS

Abstract Terahertz near-field imaging enables high-resolution biomedical and material characterization by combining the non-ionizing nature of terahertz radiation with sub-wavelength spatial resolution. However, the scalability of existing solid-state near-field imagers is fundam...

Regressive Saccades During Reading: Effects of Target Distance and the Role of Individual Differences in Spatial Memory and Linguistic Skill

The current study examined the control of long-range regressive eye movements during sentence reading. Skilled readers were asked to read single-line sentences for comprehension. As a secondary task, they identified a probe word presented to the right of each sentence, and then w...
