UAV-based aerial imagery plays a vital role in detecting surface cracks in mining-induced areas for geological disaster early warning and safe production. However, detection is challenged by small crack size, complex morphology, large scale variation, and uneven spatial distribution, further exacerbated by UAVs' limited onboard computational capacity. To tackle these issues, we introduce an efficient and lightweight small-target detection model, namely YOLO-LSN, which is built upon the optimized YOLO architecture.

Optical memristors represent a monumental leap in the fusion of photonics and electronics for neuromorphic computing and artificial intelligence. Here, we reveal the first lead zirconate titanate (PZT) optical memristor, working with a paradigm of functional duality: non-volatile setting and ultrafast volatile modulation via the Pockels effect. Fine-tuning and large modulation depth are achieved with an index change of 4.

The accumulation of foam cells in the arterial walls is a defining characteristic of atherosclerosis. Enhancing their migration from plaques may represent a key strategy for slowing disease progression. Recent studies suggest that fucosyltransferase 8 (Fut8) impairs macrophage migration from the intima by modifying the Unc5b membrane receptor, thereby influencing the development of atherosclerosis.

Background: Trimethylamine N-oxide (TMAO) is a metabolite produced by gut microbiota, and its potential impact on lipid metabolism in mammals has garnered widespread attention in the scientific community. Bovine fatty liver disease, a metabolic disorder that severely affects the health and productivity of dairy cows, poses a significant economic burden on the global dairy industry. However, the specific role and pathogenesis of TMAO in bovine fatty liver disease remain unclear, limiting our understanding and treatment of the condition.

Introduction: Postpartum dairy cows are susceptible to negative energy balance caused by decreased feed intake and the initiation of lactation. Sijunzi San, a famous Chinese traditional herbal formulation, can promote gastrointestinal digestion and absorption and improve disorders of intestinal microbiota. Therefore, we hypothesized that Sijunzi San might alleviate negative energy balance in postpartum dairy cows by modulating the structure of the rumen microbiota and enhancing its fermentation capacity.

Pork is an important high-value protein source that fulfills the nutritional requirements for normal growth development, repair, and metabolism. Tryptophan (Trp), a crucial amino acid for piglet growth performance and muscle development, has an essential yet unclear regulatory mechanism. To investigate the biological basis of Trp regulation of piglet muscle development and identify the related regulatory pathways, we studied 20 weaned piglets.

Introduction: Communicating complex information about haemodialysis (HD) and ensuring it is well understood remains a challenge for clinicians. Informed consent is a high-impact checkpoint in augmenting patients' decision awareness and engagement prior to HD. The aims of this study are to (1) develop a digital information interface to better equip patients in the decision-making process to undergo HD; (2) evaluate the effectiveness of the co-designed digital information interface to improve patient outcomes; and (3) evaluate an implementation strategy.

Background: Macrophage-derived foam cell formation is a hallmark of atherosclerosis and is retained during plaque formation. Strategies to inhibit the accumulation of these cells hold promise as viable options for treating atherosclerosis. Plexin D1 (PLXND1), a member of the Plexin family, has elevated expression in atherosclerotic plaques and correlates with cell migration; however, its role in macrophages remains unclear.

Seed propagation is the main method of mulberry expansion in China, an important economic forest species. However, seed germination is the most sensitive stage to various abiotic stresses, especially salinity stress. To reveal the molecular regulatory mechanism of mulberry seed germination under salt stress, flavonoid metabolomics and transcriptomics analyses were performed on mulberry seeds germinated under 50 and 100 mmol/L NaCl stress.

Circular ribonucleic acids (or circRNAs) are an emerging class of endogenous noncoding RNAs that are involved in physiological and pathological processes. Increasing evidence suggests that circRNAs play an important regulatory role in skeletal muscle development and meat quality regulation. In this study, it was found that circGUCY2C exhibits a high expression level in the longissimus dorsi muscle.

Myocyte enhancer factor-2-activating motif and SAP domain-containing transcriptional regulator () regulates its downstream through binding in its promoter regions. However, its molecular mechanism, particularly the DNA-binding sites, and coregulatory genes are quite unexplored. Therefore, to identify the genome-wide binding sites of the transcription factors and their coregulatory genes, chromatin immunoprecipitation sequencing was carried out.

As one of the important traits in pig production, meat quality has important research significance and value. Intramuscular fat (IMF) content is one of the most important factors affecting pork quality. Many experimental studies have shown that IMF content is closely related to the flavor, tenderness, and juiciness of pork.

Background: N-methyladenosine (mA) refers to the methylation modification of N position of RNA adenine, a dynamic reversible RNA epigenetic modification that plays an important regulatory role in a variety of life processes. In this study, we used MeRIP-Seq and RNA-Seq of the longissimus dorsi (LD) muscle of adult (QA) and newborn (QN) Queshan Black pigs to screen key genes with mA modification involved in muscle growth by bioinformatics analysis.

Efficient mode-selective manipulation in multimode photonics has drawn much attention as a key technology for realizing scalable and flexible mode-division multiplexing (MDM) systems. A mode-selective manipulation scheme based on the modal-field redistribution assisted with subwavelength grating (SWG) structures is proposed and demonstrated for the first time. In particular, the proposed scheme focuses on manipulating the coupling coefficient as well as the ratio / for different mode channels.

Background: Shared decision-making (SDM) is important when considering whether an older patient with advanced chronic kidney disease (CKD) should be managed with dialysis or conservative kidney management (CKM). Physicians may find these conversations difficult because of the relative paucity of data on patients managed without dialysis.

Methods: This prospective observational study was conducted in a unit supported by a multidisciplinary Kidney Supportive Care (KSC) programme, in a cohort of 510 patients (280 CKM and 230 dialysis) ≥65 years of age with CKD stages 4 and 5.
