Sensorless Junction Temperature Estimation of Onboard SiC MOSFETs Using Dual-Gate-Bias-Triggered Third-Quadrant Characteristics.

Silicon carbide (SiC) metal oxide semiconductor field-effect transistors (MOSFETs) are a future trend in traction inverters in electric vehicles (EVs), and their thermal safety is crucial. Temperature-sensitive electrical parameters' (TSEPs) indirect detection normally requires additional circuits, which can interfere with the system and increase costs, thereby limiting applications. Therefore, there is still a lack of cost-effective and sensorless thermal monitoring techniques.

Cellular Senescence in Hepatocellular Carcinoma: Immune Microenvironment Insights via Machine Learning and In Vitro Experiments.

Hepatocellular carcinoma (HCC), a leading liver tumor globally, is influenced by diverse risk factors. Cellular senescence, marked by permanent cell cycle arrest, plays a crucial role in cancer biology, but its markers and roles in the HCC immune microenvironment remain unclear. Three machine learning methods, namely k nearest neighbor (KNN), support vector machine (SVM), and random forest (RF), are utilized to identify eight key HCC cell senescence markers (HCC-CSMs).

Response of Soil Bacteria to Short-Term Nitrogen Addition in Nutrient-Poor Areas.

Increasing nitrogen (N) addition induces soil nutrient imbalances and is recognized as a major regulator of soil microbial communities. However, how soil bacterial abundance, diversity, and community composition respond to exogenous N addition in nutrient-poor and generally N-limited regions remains understudied. In this study, we investigated the effects of short-term exogenous N additions on soil bacterial communities using quantitative polymerase chain reaction (PCR) and Illumina Miseq sequencing in an in situ N addition field experiment.

Low-grade mucinous neoplasm originating from intestinal duplication: a case report and review of the literature.

Background: Low-grade mucinous neoplasms typically originate from the appendix and are characterized by a lining of low-grade mucus-secreting columnar epithelial cells and smooth muscle. However, atypical origins can occur, as demonstrated in this case report.

Case Presentation: We present a case involving a 33-year-old male who, upon physical examination, was found to have an abdominal mass.

Metagenomic and enzymatic mechanisms underpinning efficient water treatment of 2-ethylhexyl diphenyl phosphate (EHDPP) by the microbial consortium 8-ZY.

The ubiquitous presence, potential toxicity, and persistence of 2-ethylhexyl diphenyl phosphate (EHDPP) in the environment have raised significant concerns. In this study, we successfully isolate a novel microbial consortium, named 8-ZY, and we demonstrate its remarkable ability to degrade EHDPP using an extremely low concentration of the inoculate. A total of 11 degradation metabolites were identified, including hydrolysis, hydroxylated, methylated, glucuronide-conjugated, and previously unreported byproducts, enabling us to propose new transformation pathways.
