A systematic phytochemical investigation of the leaves of Crataegus almaatensis Pojark., an endemic hawthorn species native to the mountainous regions of Kazakhstan, was carried out. Multi-step chromatographic fractionation, comprising ultrasound-assisted methanol extraction, seq...

Listing-Time PE Involvement, ESG Talk–Do Correspondence, and Private Firms’ Productive Development

Using panel data on Chinese A-share listed private enterprises from 2009 to 2023, this study examines the relationships among listing-time private equity (PE) backing, ESG communication, externally rated ESG practices, and subsequent total factor productivity (TFP). TFP is interp...

Eco‐Friendly, Multifunctional Antibacterial Chitosan/Covalent Organic Framework Composite Films via Molecular Weaving for Fruit Preservation

ABSTRACT Chitosan‐based eco‐friendly packaging materials present a promising route to alleviate mitigating greenhouse gas emissions and global climate change by replacing traditional petroleum‐based packaging materials used for food preservation. Nevertheless, the practical appli...

Flavor quality evaluation and discrimination of regional tea (Camellia sinensis L.) based on metabolomics, volatileomics, and machine learning

This study aimed to elucidate the differences in the composition of the flavor molecular basis of fresh tea leaves ( Camellia sinensis L.) from different regions and their potential for geographical discrimination. The samples from eight representative producing areas across Chin...

Yeast Protein-Derived Peptides Protect against Ethanol-Induced Acute Gastric Mucosal Injury: Isolation, Identification, and Potential Mechanisms

Abstract Ethanol-induced gastric mucosal injury (AGMI) is intrinsically linked to oxidative stress, inflammatory responses, and compromised mucosal defense. This study aimed to isolate bioactive peptides from yeast protein (YP) and elucidate these in vitro protective mechanisms a...

Impact of Thermal Processing and Protein Fortification on the Denaturation and Sensory Attributes of High-Protein Dairy Systems

The growing demand for high-protein dairy products, driven by the expanding markets for infant formula and nutritional supplements, has led to a higher incorporation of milk protein ingredients like milk protein concentrate (MPC) and whey protein isolate (WPI) in dairy formulatio...

Comparison and Analysis of Three Measures for High Average-Utility Itemset Mining

High average-utility itemset mining is a significant research direction in data mining. The traditional average-utility (AU) measure employs itemset length as the normalization benchmark, which mitigates the bias toward long itemsets; however, it does not adequately account for t...

Sweet tea polysaccharides alleviate inflammation and regulate intestinal homeostasis via the gut-liver axis in ulcerative colitis mice

Sweet tea ( Rubus suavissimus S. Lee) is a natural plant characterized by its low caloric content, high sweetness, and health-promoting properties, with polysaccharides being its primary active components. The sweet tea polysaccharides (STP), identified as an acidic heteropolysac...

Dual-modality modeling for depression detection using speech signals

Abstract Depression is a leading contributor to the global burden of disease and a significant barrier to both personal well-being and societal development. Yet, it remains underdiagnosed, primarily due to social stigma and limited access to clinical resources. This study propose...

From Alarms to Probabilities: Stratified Human Review, Label-Noise Correction, and Calibrated Risk Grading for Industrial Vibration Anomaly Detection

Industrial anomaly detectors emit binary alarms, but production lines need graded dispositions. Calibrating alarms into fault probabilities requires ground truth, coming only from noisy human review treated as exact. We report a deployed closed loop on a reciprocating-compressor...

Understanding digital capabilities and their relationship in digital transformation

Purpose Enterprises face barriers in digital transformation due to an unclear way to build digital capability. However, existing research on digital capability lacks a unified theoretical framework. This study aims to establish a theoretical framework to explain the formation mec...
