Health co-benefits of sustainable dietary transitions to reduced red and processed meat intake in the United Kingdom: a modelling study

Abstract Purpose Reducing meat intake and increasing plant-based food consumption are priorities for chronic disease prevention and environmental sustainability across Europe. Previous modelling has outlined how policy interventions could shift dietary patterns to align with meat...

Behavioral and Cortical Responses to Frequency Changes in Vowel-Like Stimuli in Listeners With Normal and Impaired Hearing

Objectives: This study proposes a new method for detecting cortical responses to formant frequency changes using the auditory change complex (ACC). These can be used as a proxy for discrimination performance between spectral characteristics of vowels. Design: We generated two set...

Computer-Aided Entrainer Design for Extractive Distillation Using Infinitely Sharp Splits

Abstract We present an integrated product-process design framework for ranking heavy entrainer candidates for minimum-boiling azeotrope separation, corresponding to the Serafimov class (1.0-1a), the most common such case. The framework combines computer-aided molecular design (CA...

Who supports transformative parking policies? Insights from urban population segments

Abstract Transformative parking policies aim to address transport and land-use issues in urban neighbourhoods, yet concerns over public acceptability often limit their implementation. To identify barriers and entry points for implementation, this study examines who supports trans...

Evaluation of passive NO2 removal by graphene oxide-polyacrylonitrile electrospun nanofiber membranes at indoor-relevant concentrations

Traffic-related outdoor nitrogen dioxide (NO 2 ) emissions can infiltrate indoor environments, negatively affecting indoor air quality (IAQ), particularly in buildings near urban roads. In the present exploratory study, the passive performance of graphene oxide (GO)-doped polyacr...

Measurement of turbulence energy dissipation rate by a standalone high-resolution Doppler lidar

A second-order structure-function model for lidar line-of-sight (LOS) velocities is proposed. This structure-function model corrects for turbulence filtering caused by probe volume averaging using a Gaussian weighting function. The structure function model corrects for both spati...

Crystallized: Towards Resinless Fabrication of Complex Nonlinear Spatial Forms Using Fiber-Reinforced Crystal Composites (FRCCs) and Coreless Filament Winding (CFW) Techniques

Petroleum-based resins used in fiber-reinforced composites (FRCs) offer high performance but carry a substantial environmental burden. This study investigates crystallized composites (CCs) as a resinless alternative capable of binding loose cotton reinforcement within a crystalli...

The orientation of cholesterol’s hydroxy group affects its membrane dynamics and intracellular transport

The brain, though less than 10% of body mass, contains about 25% of total cholesterol (CHL), emphasizing CHL's key role in neuronal function. Many actions of CHL are stereospecific, as shown by differences from its 3 α -hydroxy epimer, epicholesterol (epiCHL). How this minor stru...

Simultaneous band-pass Raman spectroscopy for robust noninvasive continuous glucose monitoring

Abstract The rising incidence of diabetes underscores an urgent need for accurate, user-friendly, and truly noninvasive continuous glucose monitoring (CGM). Raman spectroscopy is an attractive foundation for noninvasive CGM because it is label-free and offers direct molecular spe...

Prenatal BPA exposure is associated with a sex-stratified TF–RBP–Ccar1 splicing regulatory network, purkinje cell layer alterations, and transcriptomic concordance with PTEN I135L cerebellar organoid models

Autism spectrum disorder (ASD) is a pervasive neurodevelopmental condition characterized by social communication deficits and restricted, repetitive behaviors, exhibiting a consistent male bias in prevalence. Emerging evidence suggests that prenatal exposure to bisphenol A (BPA),...

Knowledge mobilization and work autonomy: from ambiguous directives to situated knowledge in public service delivery

Purpose This study aims to investigate how public service employees resolve the tension between ambiguous directives and concrete work situations. It explores knowledge mobilization as a social process through which directives are transformed into situated knowledge for legitimat...

Effects of heat exposure on self-reported heat strain symptoms among pregnant and postpartum women in South Africa

Abstract Heat exposure can harm pregnant and postpartum women, yet heat strain symptoms in this population remain underexplored. This study implemented a novel mobile application and assessed the environmental context of five self-reported heat strain symptoms: skin rashes, sleep...

Localization coefficients of functions with applications in partial differential equations

Abstract We identify shortcomings in two popular measures of localization of functions: the $$L^p\text {-}L^q$$ L p - L q participation ratio and the mass concentration comparison. We then introduce a novel localization measure for functions on bounded subsets of $$\varvec{R}^d$$...

Papposphaera heldalii sp. nov. (Haptophyta, Papposphaeraceae) from Svalbard

This dataset contains the digitized treatments in Plazi based on the original journal article Thomsen, Helge Abildhauge, Egge, Jorun Karin (2016): Papposphaera heldalii sp. nov. (Haptophyta, Papposphaeraceae) from Svalbard. Acta Protozoologica 55 (1): 27-32, DOI: 10.4467/16890027...

Polyethylene gasification in a bubbling fluidized bed: Operating-parameter effects on syngas, tar and soot formation

Plastic gasification offers a route to recover polymer carbon as synthesis gas; changes in operating conditions affect both syngas properties and the partitioning of carbon among gaseous, condensable, and solid products. This study investigates these effects during polyethylene g...

The Python simulations of chemistry framework: 10 years of an open-source quantum chemistry project

Over the past decade, the Python-based Simulations of Chemistry Framework (PySCF) has developed into a widely used open-source platform for electronic-structure theory and quantum chemical method development. This article reviews the major advances since the previous overview in...

First European Identification of a Partial Tacheng Tick Virus 8-like Underscores the Hidden Burden of Tick-Borne Flavivirus-like Viruses

Tick-associated viruses are an underexplored component of global viromes, and highly divergent RNA viruses often remain undetected due to low abundance and sequence divergence. Tacheng tick virus 8 (TcTV8) is a poorly characterized RNA flavivirus-like virus originally reported fr...

More often, less each: Averaging can hide opposing trends in prey occurrence and consumer stomach content

Abstract Averages of prey mass in fish stomachs are widely used to track changes in feeding. Yet, a mean over all stomachs is the exact product of two quantities—the frequency of occurrence of a prey and its mean content in the stomachs that contained it—which can move in opposit...

Stroke rate detection from accelerometer data on marine mammals

Overall dynamic body acceleration (ODBA) is widely used as a proxy for movement activity. However, for large, slow-moving animals such as cetaceans, ODBA is dominated by orientational shifts rather than dynamic movements. We argue for using stroke rate frequency as an alternative...

Dynamic response and loads analysis of a large offshore wind turbine under low-frequency wind fluctuations

Abstract. We investigate the impact of low-frequency wind fluctuations on the loads and response of a large reference offshore wind turbine. Synthetic wind fields containing low-frequency fluctuations down to 1 hr-1 are used in aeroelastic simulations with the HAWC2 code. The dyn...
