Extrusion-blown biodegradable food packaging films based on starch, gelatin, and polyester blends: A comprehensive review

Growing concerns over plastic pollution have intensified the development of biodegradable films as sustainable alternatives to conventional packaging plastics. Among available manufacturing techniques, extrusion blowing is the most industrially scalable and viable process for pro...

FMFNet: Frequency-Aware multi-scale attention with fine-grained feature fusion for sonar image semantic segmentation

Sonar image semantic segmentation is a challenging task due to low contrast, severe speckle noise, and blurred object boundaries, which constrain the representation capability of purely spatial-domain convolutional features. This paper proposes FMFNet (Frequency-Aware Multi-Scale...

Integrated CIELab, electronic nose and GC-MS recognition technology elucidate the effect of oak chip aging on sensory and flavor quality of ciders

Oak chips are cost-effective alternatives to oak barrels to accelerate aging and to modulate sensory profiles in fermented beverages. This study investigated the effects of five commercial oak chips on the appearance, aroma, and sensory quality of cider during 90 days of aging at...

Missing-Depth-Tolerant Oriented Object Detection for Day-Night Apple-Harvesting Perception

Apple-harvesting perception must remain usable when depth measurements are unavailable. This study evaluates a single four-channel YOLOv8s-OBB detector that accepts RGB-D input when depth is available and RGB-Z input, with a zero-filled fourth channel, when depth is absent. Train...

Assessing Deep Maturity of Compost: Relative Cotyledon Chlorophyll as a Complementary Indicator in Full-Scale Cow Manure Composting

Compost maturity is commonly assessed using the seed germination test, which mainly reflects below-ground radicle growth. However, composts that meet conventional maturity criteria may still inhibit above-ground seedling development. This study assessed the deep maturity of compo...

Genomic analysis of phosphate-solubilizing bacteria Enterobacter ludwigii I42 and its impact on maize growth

Phosphorus (P) is an essential macronutrient required for optimal plant growth, yet its limited bioavailability in soil often restricts crop growth and yield. Phosphate-solubilizing bacteria (PSB) have the capacity to convert insoluble inorganic and organic P into forms readily a...

Mechanisms Underlying Differential Flusulfinam Sensitivity between Oryza sativa and Echinochloa crus-galli

Abstract Flusulfinam is a novel postemergence HPPD-inhibiting herbicide with excellent safety on direct-seeded indica rice, but the mechanism underlying its selectivity between rice and Echinochloa crus-galli remains unclear. Rice exhibited 41–141-fold higher GR50 values than E....

Molecular Polarity in Conjugated Microporous Polymers for Efficient CO2 Photoreduction

Abstract Donor–acceptor (D–A) conjugated microporous polymers (CMPs) are a promising class of metal-free photocatalysts for CO2 reduction. However, conventional D–A CMP design strategies that prioritize the screening of isolated D and A units based solely on energy-level offsets...

Sulfur and polymer coating on urea enhances antioxidant defense, nutrient balance, secondary metabolites, and nitrogen use efficiency in salt‑stressed wheat

Soil salinity is a growing threat to wheat productivity. This study evaluated whether different coated urea formulations– especially polymer-sulfur-coated urea (PSCU) – could help wheat cope with different salt stress levels: non-saline control (1.3 dS m − 1 , showing the natural...

Quercetin Ameliorates Cognitive Impairment in Obese Mice by Activating the PI3K/AKT/GSK3β Signaling Pathway via the Microbiota–Gut–Brain Axis

Abstract Obesity and its associated insulin resistance are important risk factors for cognitive impairment. In this study, a 10-week C57BL/6 mouse model was established to investigate the effects of dietary quercetin supplementation at 0.05% (w/w) on HFFD-induced obesity-related...

Tungsten in Agricultural Soil Triggers Coordinated Bioenergetic Responses and Gut Microbiome Dysbiosis in Earthworms: Implications for Agricultural Soil Health

Abstract Tungsten (W) can accumulate in agricultural soils near mining, smelting, industrial, and waste-disposal sites, yet its chronic effects on beneficial soil fauna remain poorly understood. Eisenia fetida were exposed for 28 d to soil W concentrations selected with reference...

Vibratory Conveying and Distributor Experiment of Rehydrated Pellet Feed for Silkworms Based on the Discrete Element Method

To solve the problems of low efficiency, poor uniformity and high labor intensity in the manual distribution of rehydrated pellet feed for young silkworms, a distributing machine for silkworm rehydrated pellet feed was developed. According to the feeding requirements of 1st- and...

Spatial and single-nucleus transcriptomics reveal the complexity of genomic imprinting in maize

Genomic imprinting is a classic epigenetic phenomenon first discovered in maize, which occurs predominantly in the triploid endosperm and is thought to mediate parental influences on seed development. Previous studies based on bulk RNA sequencing of manually dissected endosperm h...

Non‐Coding Transcripts From Diversified Members of IgLec Family Protect Antiviral Effectors From Viral miRNA

ABSTRACT Immune gene families frequently produce numerous non‐coding transcripts, yet their biological functions remain largely unexplored. Here, using the arthropod immunoglobulin domain‐containing lectin ( IgLec ) family as a paradigm, we provide evidence that this complexity m...

ZmWGSL2 Is a Candidate Chloroplast-Localized PPR Gene Associated with Chloroplast Development and Leaf-Colour Formation in Maize

Efficient chloroplast development underpins photosynthetic efficiency, biomass accumulation, and ultimately crop productivity. In this study, we characterized wgsl2-0, a stable white-green striped leaf mutant isolated from an ethyl methanesulfonate-mutagenized RP125 population of...

A novel positive feedback regulatory loop, TGF-β1/SMAD4/miR-184, controls the follicular development in sows.

transcription by binding to its promoter and forming an RNA-induced transcriptional activation complex with AGO2, CTR9, DHX9, and RNA polymerase II. Consequently, a novel positive feedback loop (TGF-β1/SMAD4/miR-184) was identified. In vitro GC and follicle culture systems valida...

Large‐scale nuclear and plastid phylogenomic analyses inform an updated Angiosperm Phylogeny Group classification: APG V

Abstract We present here a revision of the APG classification that considers the extensive recent analyses of hundreds of nuclear and plastid genes for many angiosperm species. Although previous versions of the APG classification were largely based on uniparentally inherited mark...

Study on the slurry characteristics and combustion mechanism of modified coal gasification fine slag-coal water slurry

In this study, carbon-rich gasification fine slag (RCGFS) was modified using emulsified asphalt (EA) to produce modified RCGFS (MRCGFS), which was used to prepare carbon-rich gasification fine slag-coal water slurry (MRCGFS-CWS). Concurrently, the slurry formation properties and...
