Limited structural reliability in public educational prediction benchmarks: a four-dimension audit of seven datasets

Abstract Across seven public educational prediction datasets, three passed all four pre-modeling reliability checks; the remaining four either failed group-aware generalization tests or lacked the provenance metadata needed to run them. One dataset was initially classified as fai...

Corporate digital transformation, ESG performance and carbon emissions

This study selects data from A-share listed companies from 2010 to 2023 as a sample to empirically examine the impact of corporate digital transformation on carbon emissions and ESG performance's intermediary function. According to the study, corporate digital transformation can...

Dietary Supplementation with Multispecies Probiotic Fermented Broth Improves Nutrient Digestibility and Carcass Traits While Modulating the Cecal Microbiota and Thigh Muscle Fatty Acid Profile in Yellow-Feathered Broilers

This study evaluated the effects of dietary supplementation with 4% multispecies probiotic fermented broth (MPFB) on the apparent nutrient digestibility, carcass traits, serum immune indices, intestinal morphology, cecal microbiota, and thigh muscle nutrient composition in 815-st...

Optimal standardized ileal digestible lysine levels in low-protein diets: Effects on performance of lactating sows and their offspring.

> 0.05). A nonlinear fitting of sensitive indicators with linear and quadratic effects was conducted to estimate optimal SID Lys requirements for lactating sow. Breakpoints for 14 d SUN, maximizing piglet benefits (weaning litter weight and individual weight), and sow BW loss wer...

Direct evaporation of single-crystal metal contacts for 2D semiconductors

Metal contacts remain one of the key bottlenecks in two-dimensional (2D) semiconductor electronics. We developed an atomic-scale step-by-step evaporation method to directly grow single-crystal metals on monolayer semiconductors with clean interfaces. This method accesses a distin...

Genomic predisposition is associated with the direction of sex chromosome evolution

Sex chromosome evolution is among the most dynamic genomic innovations in vertebrates, yet why some lineages evolve XY while others evolve ZW remains unclear. Using chromosome-level genomes from 19 geckos, we found that gecko sex chromosomes originated independently from 16 ances...

Gating hole back-transfer with molecular spacers programs rapid micropollutant decontamination

Precise control of oxygen activation to generate reactive oxygen species (ROS) for on-demand micropollutant removal remains challenging. Herein, we develop a bottom-up molecular approach to systematically tailor dithienyl spacers (alkene/alkyl/benzene), from model fragments, amor...

How does knowledge integration translate digital technologies into new quality productivity?

Purpose This study aims to explore how and whether digital technology (DT) is positively associated with the development of New Quality Productivity (NP) in carbon-intensive enterprises. Design/methodology/approach Grounded in the Knowledge-Based View (KBV), this paper uses panel...

Chronic arsenic exposure induces hepatic lipid metabolism disorder by regulating the FXR/SREBP1 signaling pathway

Arsenic is a widespread environmental metalloid contaminant that primarily targets the liver, inducing hepatic injury and metabolic disturbance. However, the precise mechanisms underlying chronic arsenic exposure-induced hepatic lipid dysregulation have not been fully elucidated....

Mannooligosaccharides modulate mucin O-glycan–gut microbe interactions and preserve the intestinal barrier in weaned piglets

Abstract Background The intestinal microbiota and mucosal barrier are closely intertwined, with mucin O-glycans playing a key role in maintaining intestinal homeostasis. However, how nutrition regulates mucin O-glycans remains poorly understood. This study investigated the regula...

Phase Transition Mediated Solvation Structure Regulation in Quasi‐Solid‐State Composite Electrolyte for High‐Voltage Sodium Batteries

ABSTRACT Quasi‐solid‐state composite electrolytes (QSSEs) represent a promising approach to fabricating high‐energy rechargeable batteries, but their practical implementation is hindered by structural instability and interfacial incompatibility. In this study, a QSSE was prepared...

Kiwifruit Bacterial Canker Susceptibility of 86 Accessions and Their Physiological Response to Psa Inoculation

Kiwifruit bacterial canker, caused by Pseudomonas syringae pv. actinidiae (Psa), severely restricts the sustainable development of the kiwifruit industry. Screening stable resistant germplasm and establishing efficient disease resistance evaluation methods are core prerequisites...

A Gapless T2T Genome and Population-Scale Resequencing of Adzuki Bean Reveal Centromere Evolution and Accelerate Molecular Breeding

Abstract The adzuki bean (Vigna angularis) is an economically and nutritionally significant legume species. Using a multi-strategy sequencing approach, a gapless, telomere-to-telomere (T2T) genome assembly of an elite cultivar, Jihong 16 (JH16), was generated. The genome size was...

Ultrafast Auger-MediatedInterlayer Electron Transferin 2D Perovskites: Ab Initio Quantum Dynamics Simulation

Abstract Interlayer charge transport in two-dimensional perovskites is limited by the electronically insulating nature of spacer cations. Here, we identify an unconventional, highly efficient mechanism that overcomes this limitation. Ab initio quantum dynamics reveals that spacer...
