Microfluidic-based high-throughput isolation enhances the recovery of novel strains and diversity from Arctic soil microbiome

ABSTRACT Microbial cultivation remains essential for understanding the physiology, ecology, and biotechnological potential of environmental microbes, yet conventional plate-based methods (CPM) recover only a minute fraction of the environmental microbiome. Polar regions, particul...

All-dielectric grating quasi-BIC for upconversion luminescence enhancement and cryogenic temperature sensing

Upconversion nanoparticles (UCNPs) are limited in their applications in non-contact temperature measurement and biomedicine due to their low luminescence quantum efficiency. Traditional surface plasmon resonance (SPR) structures are restricted in their performance and practical a...

Cryo‐EM Structures of Sunflower Amyloid Fibrils Reveal Two Distinct Disulfide‑Linked Assembly Modes

ABSTRACT Sunflower meal is an abundant but underutilized plant protein source. Recent studies have demonstrated that its amyloid fibrils exhibit exceptional functional properties, yet the atomic‐level structural basis remains unknown. The first cryo‑electron microscopy (cryo‑EM)...

Coronary CT Angiography‐Derived Plaque and Hemodynamic Characteristics for In‐Stent Restenosis: A Self‐Controlled Study

ABSTRACT Background In‐stent restenosis (ISR) after percutaneous coronary interventions (PCI) remains a significant challenge. Aims This study aimed to investigate the predictive ability of coronary CT angiography (CTA) derived plaque and hemodynamic characteristics for ISR. Meth...

Dynamic driver behavior modeling with GMM for sustainable traffic signal control in deep reinforcement learning

Adaptive traffic signal control is crucial for improving urban mobility and supporting environmental sustainability. Driver behavior heterogeneity has a significant impact on intersection performance, but its effective integration into reinforcement learning models remains challe...

Truck–Drone Collaborative Location-Routing Optimization for Emergency Supplies Considering Flood Impact Evolution and Stage-Specific Response

Flood disasters evolve through distinct stages, and emergency supply demand shifts accordingly, rendering static post-disaster distribution plans inadequate for stage-specific rescue needs. This study develops a multi-stage location-routing optimization model that integrates floo...

Firm-Level Exposure to Climate Policy Uncertainty and Green Innovation: Nonlinear Evidence from Chinese Listed Firms

Climate policy uncertainty may prompt firms to prepare for regulation while delaying irreversible green investment. We examine whether firm-level exposure is nonlinearly associated with green innovation. Exposure combines a news-based provincial climate policy uncertainty index w...

Exploratory Temporal Dynamics of Heart-Rate Variability During a Prolonged 2-Back Task Under Nap-Deprivation Conditions

Mental fatigue is commonly studied using prolonged cognitive tasks, but physiological changes observed in single-group paradigms may also reflect time-on-task, circadian variation, nap deprivation, posture, and cognitive load. This exploratory study characterized continuous heart...

Preparation and Catalytic Performance of Ni/γ-Al2O3 Catalysts for the Reverse Water–Gas Shift Reaction

Selective CO2 hydrogenation over Ni-based catalysts requires control of the competing reverse water–gas shift (RWGS) and methanation pathways. Here, γ-Al2O3-supported Ni catalysts with nominal loadings of 5, 10, 15 and 20 wt% were prepared by wet impregnation. Structural, textura...

Decoupling the roles of porosity and permeability in thermally driven Rayleigh–Taylor instability: a REV-scale lattice Boltzmann study

Rayleigh–Taylor instability (RTI) in porous media affects mixing and transport in carbon geological storage, solar ponds, and thermal-energy systems. This study numerically investigates thermally driven RTI between two miscible fluids in a homogeneous porous medium at the represe...

Screening and identification of novel peptides stimulating GLP‐1 secretion from plant proteins after simulated gastrointestinal digestion

Abstract Glucagon‐like peptide‐1 (GLP‐1), secreted by enteroendocrine L cells, plays a crucial role in glucose homeostasis and appetite regulation. The identification of food‐derived bioactive compounds capable of stimulating endogenous GLP‐1 secretion has attracted increasing at...

Evolutionary Characteristics and Trends of the Cross-Border Integrated Logistics Network in Inland Provinces Driven by China-Europe Railway Express and Land-Sea Intermodal Transport

Since the launch of the Belt and Road Initiative (BRI), significant changes have taken place in the cross-border trade and logistics corridor systems of China’s inland provinces. Taking 18 inland provinces along the Belt and Road as the research objects, this study constructs a c...

Development of an Olfactory Receptor (OR5K1)-Based Biosensor for Pyrazine Detection in Foods

Pyrazines are the key odorants in food contributing to baked and nutty aromas. In order to improve practicality, a novel electrochemical olfactory biosensor for pyrazine analysis was developed using an olfactory receptor (OR5K1) as the recognition element and AuNPs-PB/ZIF-8@SWCNT...

A corporate bond pricing model incorporating step-function dividends and credit rating migration

We develop a credit rating migration model with step-function dividend rates. The model incorporates two prescribed thresholds: a credit rating migration boundary and a dividend-rate adjustment boundary, which divide the firm's asset dynamics into three distinct regions. Using a...

Revealing Non-Steady-State Structure–Performance Relationship in Plateau-Capacity-Dominated Hard Carbon Anodes for High-Rate Reversible Sodium Storage

Abstract The sodium storage structure–performance relationship of hard carbon anodes has long been regarded as an intrinsic material property and forms the basis for electrode design. This common view, however, does not hold with varying operating temperatures. At room temperatur...

Source-Free Domain Adaptation with Vision-Language Prior

Abstract Source-Free Domain Adaptation (SFDA) seeks to adapt a source model, which is pre-trained on a supervised source domain, for a target domain, with only access to unlabeled target training data. Relying on pseudo labeling and/or auxiliary supervision, conventional methods...
