The grid-connected inverters (GCIs) controlled by traditional Current-Source Mode (CSM) and Voltage-Source Mode (VSM) face challenges in simultaneously meeting the requirements for small-signal stability, power-response, and grid-support. The CSM-controlled GCI excels in small-signal stability and p...

Machining centers are complex systems that consist of multiple subsystems. When maintaining these subsystems, considering opportunistic maintenance can prevent frequent shutdowns during the machining process and reduce costs. This paper proposes an opportunistic maintenance strategy for machining ce...

Species within Corydalis are valued for medicinal and ornamental uses but taxonomic uncertainties persist due to limited genomic data. Here, we present the complete chloroplast genome of C. wilsonii, with a quadripartite structure of 191,388 bp and 140 functional genes. Phylogenetic analysis robustl...

Epidemiology studies suggested that exposure to Per- and Polyfluoroalkyl Substances (PFAS) might elevate the incidence of Gestational Diabetes Mellitus (GDM), but no study considered the modifying roles of vitamin D, an important nutrient related to GDM development. Thus, this study evaluated the mo...

Background Psathyrostachys juncea is an popular perennial grass for both mowing and grazing when used for pasture establishment in high latitude regions. P. juncea has the advantages of high yield, high quality, good palatability and high nutritional value. It is widely used in artificial grassland...

Due to the short duration and complexity of ship shock responses, the shock response spectrum(SRS) is commonly used as a tool for analyzing these responses. To address the conflict between calculation speed and accuracy inherent in traditional SRS solving methods, this paper proposed a deep learning...

Different nitrogen (N) forms may cause changes in the metabolic profiles of plants. However, few studies have been conducted on the effects of amino acid-N on plant metabolic profiles. The main objective of this study was to identify primary metabolites associated with amino acid-N (Gly, Gln and Ala...

# Background Exocrine pancreatic insufficiency (EPI) is a serious condition characterized by a lack of functional exocrine pancreatic enzymes and the resultant inability to properly digest nutrients. EPI can be caused by a variety of disorders, including chronic pancreatitis, pancreatic cancer, and...

Potassium (K), a critical macronutrient for the growth and development of Korla fragrant pear (Pyrus sinkiangensis Yu), plays a pivotal regulatory role in sugar-acid metabolism. Furthermore, K exhibits a highly specific response in near-infrared (NIR) spectroscopy compared to elements such as nitrog...

The emergence of next-generation sequencing (NGS) has significantly improved the detection rate of Actinomyces species in pulmonary actinomycosis (PA), a rare and diagnostically challenging infectious disease. Here, we report a case of an elderly patient with a history of pyoderma gangrenosum who pr...

ABSTRACT: A detailed understanding of the distribution and potential of natural gas hydrate (NGHs) resources is crucial to fostering the industrialization of those resources in the South China Sea, where NGHs are abundant. In this study, this study analyzed the applicability of resource evaluation m...

In order to study the effect of Cu on the origin and propagation of pitting corrosion of super austenitic stainless steel, the immersion test results showed that Cu reduced the pitting temperature of super austenitic stainless steel and promoted the nucleation of corrosive pitting. With the analysis...

Interpreting the drivers of housing price dynamics is essential for promoting sustainable urban development, particularly in rapidly urbanizing cities in China. We adopted a data-driven approach by integrating Random Forest (RF) with SHAP (SHapley Additive Explanations) to enhance model interpretabi...

Quorum sensing (QS) is a type of microbe-microbe communication system that is widespread among the microbial world, particularly among microorganisms that are symbiotic with plants and animals. Thereby, the cell-cell signalling is likely to occur in an anaerobic rumen environment, which is a complex...
