Research on solid-state lasers with adjustable pulse width based on the controllable release of the inverted population.

A laser with an adjustable pulse width is very important for laser processing and scientific research. In this study, we propose a theoretical model to adjust laser pulse width by controlling the diffraction loss of the resonator cavity in an acousto-optic Q-switched solid-state laser system. The varies of the diffraction loss are in accordance with a set function, then modulating the release of the inverted population.

Combining genetic and non-genetic factors to predict the risk of pancreatic cancer in patients with new-onset diabetes mellitus.

Background: Recent research suggests that new-onset diabetes mellitus (NODM) often results from pancreatic cancer (PC) rather than causing it. Determining if NODM is type 2 diabetes mellitus (T2DM) or PC-related NODM (NODM-PC) aids in the early diagnosis of PC. We developed a NODM-PC risk prediction model to stratify PC risk in patients with NODM.

Comprehensive characterization of early-onset lung cancer, in Chinese young adults.

Early-onset lung cancer in young adults represents a less studied clinical entity with increasing incidence which still affects a large number of cancer patients. Here we perform a comprehensive analysis of early-onset lung cancer for the clinicopathological features, genomic alterations, gene expression, and immune landscape by establishing a cohort enrolling 421 non-small cell lung cancer (NSCLC) patients from ten medical centers in China. Comparative analysis reveals a distinct genomic alteration between younger and elder patients with NSCLC, with ERBB2 mutations and ALK-rearrangement strikingly more frequent in younger group.

Endosomal Trafficking Bypassed by the RAB5B-CD109 Interplay Promotes Axonogenesis in KRAS-Mutant Pancreatic Cancer.

Perineural invasion (PNI) represents a unique biological feature associated with poor prognosis in pancreatic ductal adenocarcinoma (PDAC), especially in the presence of KRAS mutations. Extracellular vesicle (EV)-packaged circular RNAs (circRNAs) function as essential mediators of tumor microenvironment communication, triggering PDAC cell invasion and distant metastasis. However, the regulatory mechanisms of EV-packaged circRNAs in the PNI of KRAS-mutant PDAC have not yet been elucidated.

Genome-wide association study and candidate gene identification for agronomic traits in 182 upward-growing fruits of C. frutescens and C. annuum.

Pepper agronomic traits serve as pivotal indicators for characterizing germplasm attributes and correlations. It is important to study differential genotypic variation through phenotypic differences of target traits. Whole genome resequencing was used to sequence the whole genome among different individuals of species with known reference genomes and annotations, and based on this, differential analyses of individuals or populations were carried out to identify SNPs for agronomic traits related to pepper.
