Exploring the dual mechanisms of organic fertilizers in regulating Cd bioavailability in soil: Abiotic immobilization and microbially driven processes

Cadmium (Cd) contamination in agricultural soils threatens global food safety. Organic fertilizers (OFs) are renewable soil amendments with considerable potential for regulating Cd bioavailability. However, how abiotic reactions interact with microbially mediated processes under...

Serial Cross‐Sectional Mapping of Bone Marrow Microenvironment Remodelling During Fracture Repair Using Multiparametric MRI and Histopathology

ABSTRACT Restoring bone marrow microenvironment (BMM) homeostasis is critical for fracture healing, yet non‐invasively tracking physiological events like apoptosis, angiogenesis and matrix remodelling remains challenging. This study evaluated multiparametric 7.0T MRI (T2 mapping...

Synthesis and biological characterization of formononetin derivatives against phytopathogenic oomycete and bacteria: preliminary mechanisms, theoretical predictions, and biosafety evaluation

Abstract Background The increasing prevalence of phytopathogenic oomycetes and bacteria, particularly Phytophthora capsici ( Pc ) and Xanthomonas oryzae pv. oryzae ( Xoo ), poses severe threats to global agricultural production. Developing novel antimicrobial agents with dual ant...

Numerical design of a low-frequency broadband underwater sound-absorbing metastructure with a folded water channel and air cavity

Achieving low-frequency underwater sound absorption within a subwavelength thickness remains challenging. This numerical study uses a coupled acoustic-solid finite-element model to investigate a folded rubber-lined water channel backed by a sealed air cavity under normal incidenc...

Study on performance enhancement and heat transfer regulation simulation of phosphogypsum-based phase change cementitious material

Phosphogypsum-based building materials hold great promise as a key method for managing solid waste. However, their limited thermal storage capacity restricts their widespread application in engineering. In this study, microcapsule phase change materials (MPCMs) were introduced to...

Host Pre-Adaptation and Sublethal Indoxacarb Interactively Affect Growth and Development of Cnaphalocrocis medinalis, with Potential Involvement of P450 and Juvenile Hormone-Related Genes

Host switching alters insecticide responses, but its interplay with sublethal stress remains unclear. We examined if host pre-adaptation modulates sublethal indoxacarb effects on Cnaphalocrocis medinalis and whether P450 and juvenile hormone-related genes are involved. Two long-t...

PCR: A Prefetch-Enhanced Cache Reuse System for Low-Latency RAG Serving

Retrieval-Augmented Generation (RAG) significantly improves Large Language Models (LLMs) but introduces massive input sequences that severely bottleneck the prefill stage. While KV-cache reuse reduces redundant computation for shared document prefixes, the reusable KV working set...

Comparative chloroplast genomics of Medicago: codon usage bias, purifying selection, and phylogenomics

Medicago sativa subsp. falcata (yellow-flowered alfalfa) is an essential genetic resource for forage improvement, biofuel production, and sustainable agriculture. Its superior cold tolerance and drought resistance, compared with common alfalfa, make it suitable for cultivation in...

Revolutionizing drought defense: The water-plant-microbe synergy in climate-smart agriculture

Global warming-induced water scarcity threatens agricultural sustainability. While precision irrigation and microbial inoculants are recognized as effective individual strategies, their synergistic potential remains under-explored. This review synthesizes recent advances in the "...

Numerical study on leakage diffusion characteristics and hazard boundaries of buried hydrogen-blended natural gas risers

Leakage from buried hydrogen blended natural gas (HBNG) pipelines can cause gas migration through porous soil and accumulation at the ground surface, creating fire and explosion hazards. Vertical risers, owing to stress concentration and distinct leakage patterns, exhibit hazard...

Multi-subpopulation quantum particle swarm optimization with dual chaotic encoding for flexible job-shop scheduling problem

The flexible job-shop scheduling problem (FJSP) is a fundamental challenge in modern manufacturing and artificial intelligence (AI) due to its NP-hard complexity. Efficiently solving the FJSP requires balancing solution quality, computational efficiency, and convergence speed, bu...
