Genomic characterization and immunoinformatics analysis of the Brucella melitensis vaccine strain BA0711

B. melitensis BA0711 is a novel genetically engineered attenuated live vaccine strain constructed by the targeted deletion of the cold shock protein A (CspA) gene. While previous studies demonstrated its safety and protective efficacy in animals, its underlying comparative genomi...

Enhancing Shadow Fading Mitigation with RIS Using Two-Dimensional Orthogonal Pattern Division Multiple Access

This paper addresses multipath interference introduced by reconfigurable intelligent surface (RIS) in mitigating shadow fading in wireless communication systems. To tackle this, we propose the use of two-dimensional orthogonal pattern division multiple access (OPDMA) with optimal...

Soil Carbon Fractions and Aggregation Regulate N 2 O Emissions and Microbial N‐Cycling Genes: A Case Study Across Tropical Paddy Soils With Contrasting Organic Matter Levels

ABSTRACT Background : Nitrous oxide (N 2 O) is a major greenhouse gas, and its production is shaped by soil organic matter (SOM). Yet, how different SOM‐derived labile carbon fractions regulate N 2 O remains unclear, especially in tropical paddy soils where weak SOM stabilization...

Anchoring Polyiodides: Microphase-Separated Gel Polymer Cathode for Zinc–Iodine Batteries

Abstract Zinc–iodine (Zn-I2) batteries are attractive for grid-scale energy storage owing to safety and low cost, yet practical deployment is hindered by shuttling of soluble polyiodide intermediates (I3–, I5–), which causes capacity decay, anode corrosion, and thermal instabilit...

Cooperative Event-Triggered Forwarding with Compressed Sensing in Multi-Hop Wireless Sensor Networks

To address the degradation of state estimation accuracy induced by channel fading in multi-hop wireless sensor networks, this paper proposes a novel approach that integrates cooperative communication, compressed sensing and an event-triggered forwarding strategy. By introducing c...

Leveraging Machine Learning for Accelerated Electrode–Electrolyte Interface Design in Rechargeable Li‐Based Batteries

Due to their high specific energy, lithium-metal batteries (LMBs) are widely regarded as the promising next-generation energy storage devices. Nevertheless, their practical applications are plagued by the challenges of irregular deposition and dissolution, coupled with the high c...

ProgrammableVersatile Socket: A Tight-Locking andHigh-Gain CRISPR/Cas12a Molecular Circuit for Ultrasensitive Sensingof Diverse Targets

Abstract CRISPR/Cas12a has emerged as an important platform for nucleic acid analysis, yet limited catalytic turnover and intrinsic nucleic acid specificity constrain its sensitivity and analyte scope. Herein, a tight-locking and high-gain Cas12a-driven strand displacement amplif...

Partial soil wetting and drying regulate root water uptake in deep-rooted apple orchard

The drought-prone Chinese Loess Plateau (CLP) apple trees have roots that extend deep into the soil. Even when the upper soil layers (0–10 m) are above the permanent wilting point, deep (>10 m) root water uptake (RWU) occurs; the reasons for the deep RWU remain unknown. This stud...

Full-length transcriptome atlas of Panax vietnamensis var. fuscidiscus reveals novel genes and alternative splicing in tissue-specific biosynthesis of ocotillol-type saponins

Panax vietnamensis var. fuscidiscus is the only known Panax species that accumulates exceptionally high levels of ocotillol (OCT)-type ginsenosides, particularly majonoside R2. However, the molecular mechanisms underlying OCT-type ginsenoside biosynthesis remain largely uncharact...

Thermal‐Induced Loose Solute Configuration Activates Organic Electrolyte for Zinc Metal Battery

ABSTRACT Zinc metal batteries face issues of low coulombic efficiency and persistent side reactions due to the active H 2 O in aqueous electrolytes. Organic electrolytes that can reduce side reactions and coulombic efficiency loss still suffer from sluggish Zn 2+ transfer and dif...

A Stock Market Price Prediction Model Integrating a CNN–Transformer Dual-Channel Dynamic Attention Architecture

Stock market price prediction remains a persistent challenge owing to the non-stationarity, high noise content, and intricate spatiotemporal dependencies that characterize financial time series. Existing approaches typically excel at either local pattern extraction or long-range...

Reconciling nitrogen fertilization effects on soil nitrification with acidification

Nitrogen (N) fertilization supports nearly half of the global population but disrupts the N cycle. While N addition is assumed to stimulate soil nitrification by increasing substrate supply and nitrifier activity, it may also inhibit nitrification via soil acidification. Resolvin...

Attractancy Potentialof Terpinen-4-ol against Bactrocera dorsalis (Hendel) and Its SynergisticAttractant Effects Evaluation

Abstract Bactrocera dorsalis is a major fruit and vegetable pest with limited effective attractants. Our previous work identified Melaleuca quinquenervia essential oil (MQEO) as a strong attractant. Guided by an olfactory transcriptome- and molecular docking-informed screening st...

Magneto‐NIR‐II‐Programmed Cascade Nanozymes Unlocking Blood–Brain Barrier Translocation and Autophagic Resistance in Glioblastoma

ABSTRACT Glioblastoma (GBM) remains a highly aggressive central nervous system malignancy, and its treatment is hindered by poor drug accumulation across the blood–brain barrier (BBB) and autophagy‐mediated repair. To address these barriers, rare‐earth‐doped Nd 0.02 Fe 2.98 S 4 @...
