In the calculation of the acoustic performance of mufflers, the walls of mufflers are usually treated rigidly without considering the acoustic-structural coupling, but the results so calculated differ significantly from the actual situation. Based on the basic equations, the article derives the fini...

With the rapid proliferation of services deployed on edge servers, selecting high quality services from a multitude of functionally similar offerings based on their rankings has become a critical issue. Service ranking is an effective approach to solve this problem. Traditional QoS aware service ran...

A single-shot distributed dynamic strain sensor is proposed with high spatial resolution and broad detection bandwidth. Linear frequency modulated pulse is employed as the probe pulse, which not only solves the trade-off between spatial resolution and sensing distance, but also avoids the time-consu...

Spaceborne radar imaging is the key means to obtain the fine-resolution radar image of space targets. However, the nonuniform relative rotational motion caused by the high-speed orbital state leads to the degradation of the radar imaging performance. To address this problem, a fine-resolution spaceb...

Pre-treatment of food samples is a crucial step in food analysis and testing. Due to the complex matrix and low levels of analytes in food samples, especially for the detection of trace compounds, it is particularly important to choose appropriate sample pre-treatment techniques. Through sample pre-...

Although α-amylase is crucial for postprandial glucose control, existing inhibitors present various side effects, necessitating the exploration of natural alternatives. The ability of sugarcane polyphenol (SP) to inhibit α-amylase remains unclear. This study assessed the inhibitory activity of SP vi...

Abstract: To accurately estimate winter wheat yields and analyze the uncertainty in crop model data assimilations, winter wheat yield estimates were obtained by assimilating measured or remotely sensed leaf area index (LAI) values. The performances of the calibrated crop environment resource synthes...

Exploration types serve as a link between the morphological characteristics of hyphae in ectomycorrhizal fungi and the diverse nutrient-acquisition strategies employed by ectomycorrhizal trees. However, the influence of biological, climatic, edaphic and geomorphic factors on the prevalence of the co...

This study investigates the feasibility of replacing soybean protein isolate (SPI) with Zanthoxylum seed kernel protein (ZSKP) to produce texturized protein (TP). The results showed that adding 0–50 % ZSKP gradually caused the TP structure to crack and become porous, reducing its hardness, elasticit...

Abstract A‐type granite is a favorable rock for the study of crustal evolution, crust‐mantle interaction and metallogenesis. However, the origin of A‐type granite remains controversial. In this study, we report high‐precision Ca isotopic compositions of a co‐genetic suite of A‐type granites from the...

Although the phosphate 1 (PHO1) gene family has been implicated in inorganic phosphate transport and homeostasis, the underlying mechanism of this gene in the strawberry has not yet been revealed. In the present study, we analyzed the expression of the PH01;H9 gene in the strawberry (Fragariaxananas...

Genes controlling fruit appearance determine fruit shape and size. In ethylmethane sulfonate (EMS)-mutagenized lines of Fragaria vesca accession Yellow Wonder (YW), two fruit shapes are observed: wild-type long fruit and mutated shortened fruit (sf). In this study, we first characterized sf based on...

Auxin signaling plays a significant role in the whole process of plant growth and development from embryogenesis to senescence. Auxin response factors (ARFs) are reported to regulate the expression of auxin response genes by binding to auxin response elements. ARF is the most critical transcription...
