Accurate and real-time Earth rotation parameters (ERPs) are crucial for various scientific fields, including astronomy, geoscience, and oceanography. Although there are various space geodetic techniques, such as VLBI, GNSS, DORIS, and SLR, which can determine the ERPs with high accuracy, these metho...

Immune checkpoint inhibitors (ICIs) have gained widespread application in the treatment of malignant tumors. Cytokine release syndrome (CRS) is a systemic inflammatory response triggered by various factors, including infections and immunotherapy. We present a case of CRS occurring in a gastric cance...

Image stitching aims to align two images from different perspectives. For infrared remote sensing images, the low resolution, lack of strong-feature points, and the presence of large textureless regions make it difficult to achieve effective feature matching and high-quality image stitching results....

BackgroundHepatoid adenocarcinoma of the stomach (HAS) is a rare but highly aggressive subtype of gastric cancer (GC) associated with an unfavorable prognosis, particularly in advanced or metastatic stages. While the standard first-line treatment for advanced GC involves immune checkpoint inhibitors...

The geometry of the railway track affects rail wear significantly. If the rail wear can be predicted and considered during the alignment design phase, the problems it causes can be mitigated at the source by optimizing the values and combinations of railway track geometry parameters. However, the re...

Abstract The Type VI secretion system (T6SS) is a key virulence mechanism utilized by many Gram‐negative bacteria to mediate the microbial competition and host pathogenesis. Despite the identification of diverse T6SS effectors targeting eukaryotic or prokaryotic cells, the trans‐kingdom T6SS effecto...
