Evaluation of the Rb/Sr ratio as an indicator of chemical weathering: a case study from five sedimentary sections in Northeast China

Chemical weathering plays a pivotal role in the Earth's surface material cycle and global climate regulation. It not only facilitates the reconstruction of palaeoclimate characteristics but also provides essential insights into Earth's evolutionary history. The Rb/Sr ratio has be...

Differential Effects of Lycium Barbarum Polysaccharides and Seaweed Polysaccharides on Growth, Immunity, and Hepatic Lipid Metabolism in Juvenile Rainbow Trout (Oncorhynchus mykiss)

Polysaccharides play crucial roles in medicine and nutrition, serving as dietary additives that help maintain fish health. This study systematically evaluated the effects of dietary supplementation with plant-derived Lycium barbarum polysaccharides (LBP) and Seaweed-derived polys...

A Hierarchical Semantic Knowledge-Distilled Belief Rule Base for Interpretable Fault Diagnosis

Fault diagnosis is essential for the safe and reliable operation of industrial equipment. Deep learning models provide strong fault recognition capabilities, but offer limited transparency, while belief rule bases (BRBs) provide explicit reasoning, but face challenges in represen...

Ferrocene–Cystamine Conjugate Encapsulated Hyaluronic Acid Nanomicelles with Sequential pH/GSH Responsiveness for Synergistic Chemodynamic-Immunotherapy

Abstract Metastasis and postoperative recurrence of malignant tumors remain critical obstacles that undermine clinical therapeutic efficacy. Traditional chemodynamic therapy (CDT) is plagued by three inherent, hard-to-resolve drawbacks: abundant intratumoral glutathione (GSH) que...

Integration of cytogenetics and genomics reveals translocation and recombination between nonhomologous chromosomes in a novel wheat line with dual introgression

The development of wheat-rye-Thinopyrum hybrids is a key strategy for introgressing agronomically valuable traits from multiple genera into common wheat, enriching its genetic diversity. However, the labor-intensive and time-consuming identification of lines carrying chromatin se...

MTRC: multi-scale topology-guided residual coverage for finite-horizon SIR influence maximization

Influence maximization seeks a size-constrained seed set that maximizes diffusion under a specified propagation process. In finite-horizon susceptible–infected–recovered (SIR) diffusion, a candidate’s value depends on recovery-limited transmission paths and on propagation opportu...

Spatiotemporal Evolution and Quantitative Attribution of NDVI in the Lesser Khingan Mountains Considering Lag–Cumulative Effects

Boreal forest ecosystems across mid-to-high latitudes in the Northern Hemisphere show strong responses to climate change. Vegetation growth is influenced by cumulative climatic effects with time lags, as well as human disturbances. This study selects the Lesser Khingan Mountains...

Ultrasound-Activated FeSnO(OH)5/Cu2S Heterojunction Microneedles Coordinate Redox Catalysis and Metal-Ion Dyshomeostasis for Localized Tumor Therapy

An ultrasound-activated microneedle patch (FCSP-MN) was developed for localized tumor therapy by integrating FeSnO(OH)5/Cu2S heterojunction nanoparticles (FCS) and phloretin into pH-responsive poly(acrylic acid)/poly(vinylpyrrolidone) microneedle tips. Heterojunction formation pr...

Spatial Prediction and Performance Comparison of Soil Organic Carbon in High-Latitude Forest Soils Based on Multiple Feature Selection Methods and Machine Learning Models

Soil organic carbon (SOC) in permafrost regions is a critical component of terrestrial carbon reservoirs, and spatially explicit multi-depth mapping is essential for identifying subsurface carbon emission hotspots and supporting carbon neutrality accounting. The Kamalan River Bas...

Taxonomy and phylogeny of two new species of Frontoniidae (Ciliophora, Peniculida) isolated from black soil farmland in northeastern China

This study examined the morphology and infraciliature of two soil ciliates, Protofrontonia mudanjiangensis sp. nov. and Frontonia legumen sp. nov., collected from farmland in Mudanjiang, Heilongjiang Province, Northeastern China, using live observation and silver carbonate impreg...

TFPAG-Net: A Time-Frequency Dual-Branch Fusion and PCMCI-Based Association-Guided Network for IIoT Intrusion Detection

The Industrial Internet of Things (IIoT) is being used a lot in important areas like advanced manufacturing, smart energy systems, and intelligent cities. Watching for intrusion detection is very important for the safety of the IIoT. Nevertheless, multivariate sensor sequences fr...

Spatiotemporal Patterns and Fine-Scale Natural Capital Accounting for Land Resources in Heilongjiang Province, China

Global land degradation and the imbalance between human demand and land resource supply have become prominent challenges to regional ecological security. The compilation of a land resource balance sheet is helpful for the construction of an ecological civilization and the governa...

Integrating life cycle thinking into EU law on end‐of‐life vehicles

Abstract The European Union (EU) framework for end‐of‐life vehicles (ELVs) has progressed beyond waste disposal to formally cover vehicle design, producer responsibility and material recovery. However, it is less clear whether these provisions effectively connect across the relev...

Conservation and Targeted Wild Tending of Schisandra chinensis Under Global Change: Informed by SDMs and Fingerprint Analysis of Climate–Land–Composition Responses

Schisandra chinensis (Turcz.) Baill. is a valuable medicinal plant species, and the demand for its wild resources is increasing continuously. However, the response mechanisms of its future habitat suitability and medicinal quality to global change remain poorly understood. This s...

Waltz: Temperature-Aware Cooperative Compression for High-Performance Compression-Based CSDs

Data compression is widely adopted for modern solid-state drives (SSDs) to mitigate SSD lifetime issues. Researchers have proposed compression schemes at different system layers, including device-side solutions like CCSDs ( c ompression-based c omputational S SD s) and compressio...

YOLO-APPA for student behavior detection in classrooms using adaptive boundary aggregation and feature enhancement

Classroom behavior detection can support teaching reflection, learning engagement analysis, and classroom management by providing observable visual evidence of student activities. However, such behavioral evidence should be interpreted as an auxiliary indicator rather than a dire...

Silver Nanoclustersfor the Multivariate Sensing ofMercury Ions and Bovine Serum Albumin via Two Independent Strategies
