Current status of ocean observation, ensemble reanalysis and CMIP6 models in describing Antarctic Bottom Water

Abstract. Antarctic Bottom Water (AABW), a key component of the global meridional overturning circulation, forms in distinct regions around Antarctic coasts. The properties of AABW from different sources can be distinguished by their temperature and salinity properties. This stud...

A Three-Layered Framework and Measurement Toolkit for Understanding Emotional and Relational Engagement with AI

As generative artificial intelligence (AI) becomes increasingly embedded in emerging adults’ academic, work, and social lives, interactions with AI increasingly involve emotional disclosure and relational engagement beyond instrumental use. However, empirical research has been co...

Long-term exposure of Lactobacillus rhamnosus to quercetin enhances its anti-angiogenic and anti-colorectal cancer efficacy

Abstract Colorectal cancer (CRC) is the second leading cause of cancer death worldwide, with rising incidence projected over the coming decades. Here we show that prolonged exposure of Lactobacillus rhamnosus PTCC 1637 to quercetin (up to 200 µg/mL) improves its probiotic traits...

Interfacial Properties of MoS2 Thin Films Grown on Functional Substrates

Abstract Interface chemistry and defect formation in MoS2 thin films grown on single crystal substrates critically determine the electronic structure of MoS2 and thus can strongly modify material functionality relevant for many applications, including electronics, optoelectronics...

Development and validation of a 154-plex MPS STR panel for Illumina and Nanopore: a comprehensive tool for forensic genetic analysis

Capillary electrophoresis (CE)-based STR typing, while long established as the gold standard, is constrained by limited allele resolution and multiplexing capacity—unable to resolve variation within length-identical alleles or to simultaneously capture autosomal, X-, and Y-chromo...

Stochastic neural networks for quantum devices

Abstract This work presents a formulation to express and optimize stochastic neural networks as quantum circuits in gate-based quantum computing. Motivated by a classical perceptron, stochastic artificial neurons are introduced and combined into a quantum neural network. The Kief...

Structure-oriented deep learning for semantic segmentation of bridge point clouds

Bridges built during the post-war construction boom are reaching the end of their design life, and their inspection still relies mainly on manual visual assessment. The specific question addressed is whether bridge components can be segmented accurately and efficiently from raw p...

Koopman analysis of sea surface temperature with a signature kernel

We develop a trajectory-based Koopman method for sea surface temperature (SST) that lifts annual SST segments using a signature kernel—a reproducing kernel Hilbert space kernel that compares paths via iterated-integral features—and learns the one-year shift operator. By operating...

On k-Geodetic Edge Traceable Graph

A graph G is k-geodetic edge traceable if every edge of G lies in at least one geodesic of length k. The maximum geodesic edge-covering number $$\textrm{gec}_{\max }(G)$$ is the minimum number of largest fixed-length geodesics that cover all edges of G. We study some properties o...

Elevated Levels of Environmental Enteric Dysfunction Biomarkers Among Rural Indonesian Infants: Associations with Water, Sanitation, Hygiene and Linear Growth

Abstract Objective To investigate the burden of environmental enteric dysfunction (EED) and its association with water, sanitation, and hygiene (WASH) and linear growth amongst infants in rural Central Java, Indonesia. Study design A longitudinal study of 119 infants aged between...

Fungar: a pipeline for detecting antifungal resistance mutations directly from metagenomic short reads

Abstract Background Antifungal resistance has become an increasing global concern in both clinical and environmental health. Detecting known resistance mutations directly from metagenomic short-read sequencing data remains a major challenge. Most available tools are designed for...

Talaromyces marinus (Eurotiales, Trichocomaceae): a new marine fungus from the Red Sea, Egypt, with distinguished enzymatic capabilities

Abstract Background Talaromyces is a large and taxonomically important genus within Ascomycota, established to accommodate the teleomorphs of certain Penicillium species and now recognized as a monophyletic lineage distinct from Penicillium . Multigene analyses demonstrated that...

Expanding Oued Beht: Final Neolithic, Bronze Age, medieval and later discoveries from excavation and survey in 2023

Abstract Oued Beht, Morocco, is emerging as a key site for understanding later prehistory in the northwestern Maghreb. Previous fieldwork by the Oued Beht Archaeological Project (OBAP) in 2022 revealed major evidence of a large and complex focus of activity across the ridge durin...

Shades of Grey: Designing Privacy Workflows to Identify, Address and Avoid Damaging Data Leakage Risks via Informal Data Transfers

In academic research, data sharing, particularly secondary data reuse, relies heavily on informal networking. ‘Grey’ transfers of data motivated by research purposes are common. In this paper, working through three case studies primarily in human subject research, presented by pr...

On the intersections of projected Hamiltonian orbits in cotangent bundles

Abstract We study the generic behaviour of Hamiltonian trajectories on a regular level set in the cotangent bundle, after projection to the base. We prove that for a generic submersive level set, projected trajectories have discrete (self-)intersections. Additionally, fixing end-...

Democratic governance, public service satisfaction, and health equity in Africa: a multivariate statistical analysis

Abstract This study examines the political determinants of health access in Africa by analyzing how democratic demand, democratic supply, and perceptions of government health performance shape reported difficulty in accessing health care. We conducted a cross-sectional, multi-cou...

Bifurcation and hydra effect of a plant-herbivore model with herbivore harvesting

Adaptive management of herbivore populations during grassland plant degradation serves as a critical strategy for sustaining ecosystem stability. To address this imperative, establishing a mechanistic grassland resourceherbivore model that incorporates herbivore harvesting and ri...

CFD Analysis of an F1-Style Vehicle Using OpenFOAM

Independent CFD case study analysing external aerodynamics of an F1-style vehicle using OpenFOAM, focusing on Navier–Stokes-based turbulence modelling, meshing strategy, and aerodynamic interpretation.

Spatially-aware predictors for car subnetwork optimality region in bi-modal grids with dedicated bus lanes

Understanding the relationship between network topology and performance is essential for effective traffic management and the efficient allocation of road space among different transport modes. This study focuses on bi-modal grid networks composed of car lanes and Dedicated Bus L...

When Robots Are Abandoned: Post-discontinuation Sustainability as an Epistemological Problem

Sustainability in social robotics is often addressed at the level of individual artifact features. Yet social robots become embedded in socio-technical configurations that shape their maintenance, continued use and disposal. To investigate sustainability at this system level, the...
