Behavioural and contextual drivers of agri-environmental schemes adoption among large-scale farms in Czechia

Agriculture substantially contributes to environmental and climate change, with agri-environmental schemes (AES) often used to reduce the associated impacts. In the EU, they are publicly funded, voluntary and incentivised through financial payments, but they can encounter resista...

Design and functional verification of an automated Perkins Brailler accessory with audio feedback

PURPOSE: This study presents a proof-of-concept automated accessory designed to actuate selected functions of a standard Perkins Brailler. MATERIALS AND METHODS: The prototype uses push-type electromagnetic solenoids to operate the Brailler keys, a gear motor to support carriage...

Classification of real plastic waste using machine learning-assisted laser-induced breakdown spectroscopy

Plastic type classification using laser-induced breakdown spectroscopy (LIBS) was evaluated using actual waste samples under non-optimized experimental conditions designed to approximate laser-sample variability encountered in industrial operation. The study addresses challenges...

Whole-genome characterization and zoonotic potential of Alphacoronavirus from greater horseshoe bats (Rhinolophus ferrumequinum) collected on Jeju Island, Republic of Korea, 2009–2014

The genus Alphacoronavirus (α-CoV), belonging to the family Coronaviridae , comprises positive-sense RNA viruses that infect a broad spectrum of mammalian hosts, often facilitating cross-species transmission. Bats are recognized as the ancestral reservoirs for numerous α-CoVs tha...

The “wow” effect in metaverse luxury consumption: an appraisal-based explanation of emotional arousal and exploratory motivation

Purpose This study examines how key experiential elements, telepresence, social interaction, immersion, realism and augmented reality elicit the “wow” effect (a strong emotional response) and, in turn, shape willingness to purchase luxury goods. Design/methodology/approach A ques...

Evaluation of a fermented citrus bioconversion product: metabolic and hepatic effects in high-fat diet-fed mice

Despite growing interest in fermented citrus-derived functional ingredients, their metabolic effects in diet-induced obesity and the chemical characteristics of the fermented preparations remain insufficiently characterized. This study characterized a fermented citrus bioconversi...

Redefining post-xenotransplantation surveillance: leveraging metagenomic next-generation sequencing to discriminate true pathogen replication from microchimerism-induced false positives

Infection-related risks remain a major concern in xenotransplantation and require continued vigilance as the field progresses toward clinical application. Xenozoonosis is of particular concern, especially in relation to donor-derived porcine viruses such as porcine endogenous ret...

Revisiting Animal Reservoirs of Hantavirus and Other Zoonotic Viruses Associated with Cruise Travel: Impact and Prevention

The sustained growth of international maritime tourism and the expansion of the cruise industry have increased the importance of emerging zoonotic diseases as a significant challenge to global public health. Cruise ships constitute complex epidemiological settings characterized b...

Are the blue and the green natural allies? Mapping the public foundations of just transition worldwide

A Just Transition, with its dual goals of environmental sustainability and social equity, has gained global prominence and has been adopted as a formal policy agenda by governments and intergovernmental organizations. While broad and meaningful public support for both goals is cr...

Lobular carcinoma as a spectrum: resolving the gray zone between morphology, E-cadherin, and CDH1

Invasive lobular carcinoma (ILC) is characterized by E-cadherin loss resulting from CDH1 inactivation, but discordance among morphology, immunohistochemistry (IHC), and molecular findings can complicate diagnosis. We integrated histology, IHC, DNA sequencing, and whole-transcript...

Fermented soy protein Maillard reaction products attenuate Gardnerella vaginalis-induced vaginal and intestinal inflammation: involvement of TLR2/NF-κB suppression and short-chain fatty acid restoration

This study investigated the ameliorative effects of Maillard reaction product (MRP) and its Lacticaseibacillus rhamnosus IM18-fermented derivative (MRPF) against Gardnerella vaginalis -induced inflammation. In G. vaginalis -stimulated VK2/E6E7 cells, both MRP and MRPF suppressed...

Explainable artificial intelligence for predicting mortality in geriatric patients undergoing hip arthroplasty

We performed machine learning analysis of population data to determine the major determinants of 1-year mortality among geriatric patients undergoing hip arthroplasty. The data of 17,290 patients aged ≥ 65 years who underwent hip arthroplasty in 2019 were extracted from the Korea...

Kinetic hindrance of phase transformations in dense MgSiO 3 polymorphs under shock compression

Equilibrium phase diagrams define the pressure-temperature stability fields of MgSiO 3 polymorphs, yet whether these phase transformations can proceed under shock compression remains poorly constrained. Here, we present in situ synchrotron x-ray diffraction (XRD) measurements of...

Layer-by-Layer Electrode Design Integrating a Macroporous Carbon-Nanotube Skeleton for an Anion-Exchange Membrane Water Electrolyzer

Abstract Three-dimensional porous electrodes (anodes and cathodes) using only non-noble-metal electrocatalysts are important for enhancing the performance of anion-exchange membrane water electrolysis (AEMWE), contributing to reduced green-hydrogen production costs. This study de...

Vascular Imaging Features and Time-Specific Recurrence Risk After Craniocervical Artery Dissection

Background and ObjectivesCraniocervical artery dissection (CCAD) is a major cause of stroke in young adults, yet its recurrence risk remains poorly defined because of delayed enrollment in prior research. We aimed to determine the temporal distribution of recurrent ischemic strok...

Machine learning enabled kinetic prediction and inverse design of sonoelectrochemical oxidation: Molecular descriptor integration, applicability domain assessment, and experimental verification

Sonoelectrochemical oxidation (US-EC) is a promising method for removing emerging pollutants, but its degradation kinetics are influenced by the interactions between operating conditions, reactor characteristics, and pollutant properties. This study developed an machine learning...

PLLA–ZnO nanowire nano-vaccine orchestrates balanced Th1/Th2 immunity and confers prophylactic antitumor protection

Cancer vaccines require both cellular and humoral immunity for optimal therapeutic efficacy. We previously demonstrated that carcinoembryonic antigen (CEA)-coated poly- l -lactic acid-zinc oxide (PLLA-ZnO) nanocomposites induce strong cellular immunity and therapeutic antitumor e...

Toward AI Virtual Cells for Hepatology: Representation, Generation, Dynamics, and Intervention in Single-Cell Models

``Single-cell and spatial atlases describe the healthy and diseased liver at high resolution, including lobular hepatocyte zonation, fibrotic macrophage-stellate niches, cholangiocyte reactions, immune remodeling, and hepatocellular carcinoma ecosystems. These maps show where cel...

Metabolic health, obesity, and prognosis in chronic obstructive pulmonary disease

Metabolic syndrome is a common comorbidity in chronic obstructive pulmonary disease (COPD), yet its long-term impact on survival and exacerbations remains controversial. We investigated whether metabolic health status and body mass index (BMI) influence mortality and the rate of...
