BackgroundSarcopenia screening in bone tumor patients is challenging due to limited awareness, complex procedures, and high costs-especially since most research targets older adults, overlooking younger patients in this group. This study aims to compare the screening efficacy of five different tools...

In this study, we investigate the morphology of galaxies in the TNG100 simulation by applying mock observation techniques and compare the results with the observational data from the Sloan Digital Sky Survey (SDSS). By employing a hierarchical convolutional neural network (CNN) approach, we classify...

Aiming at the problem of poor scale invariance of traditional ORB algorithms, this paper proposes an ORB algorithm based on image golden tower. Firstly, Gauss image pyramid and B-Spline image pyramid are studied, and the two image pyramids are discussed through experiments. Experimental results show...

BackgroundIntrahepatic cholangiocarcinoma (iCCA) is a malignant tumor second only to hepatocellular carcinoma in terms of incidence among primary liver cancers. Surgical resection is currently the preferred treatment for iCCA. However, the prognostic significance, complications, and clinical benefit...

In cold-region rock engineering, freeze–thaw cycle-induced crack propagation in fractured rock masses serves as a major cause of disasters such as slope instability. Existing studies primarily focus on the influence of individual fissure parameters, yet lack a systematic analysis of the crack propag...

Grain size is a major determinant of grain weight and a trait having important impact on grain quality in rice. The objective of this study is to detect QTLs for grain size in rice and identify important QTLs that have not been well characterized before. The QTL mapping was first performed using thr...

Stakeholders in the field of food safety management in China can be classified into three categories, government, food producers (farmers and enterprises), and the third-party regulatory bodies. The third-party regulation has experienced rapid development in past twenty years, and recently received...

Soil organic carbon (SOC) plays a key role in improving soil quality and optimizing crop yield. Yet little is known about the fate of macroaggregates (>0.25 mm) under long-term fertilization and their relative importance in SOC sequestration in reclaimed calcareous soil. Therefore, the effects of...

Plants reshape their transcriptomes, proteomes and metabolomes in response to insect damage. In this study, we used suppression subtractive hybridization to investigate the transcriptomes of two cotton varieties (CCRI41 and CCRI23) under Apolygus lucorum damage. From the CCRI23 libraries we obtained...

Fruit cracking is a persistent challenge for table grape growing. To investigate the mechanism of this disorder, a comprehensive two-year investigation was conducted to assess the fruit cracking percentage of 15 table grape (Vitis vinifera L.) varieties. Based on the findings, the cracking-susceptib...
