Brain strain: Blood flow and metabolism in environmental extremes
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

Numerical simulation of gap effect in supersonic flows
The gap effect is a key factor in the design of the heat sealing in supersonic vehicles subjected to an aerodynamic heat load. Built on S-A turbulence model and Roe discrete format, the aerodynamic environment around a gap on the surface of a supersonic ...

Pre‐operative and post‐operative T2 MRI and PSMA PETCT. ABSTRACT Prostate cancer is the most commonly diagnosed cancer and the second leading cause of cancer death in men. Acinar adenocarcinoma accounts for 90% of primary prostatic cancers. Carcinoma of the basal cells of the prostate is extremely rare, making up less than 1% of prostate cancer ...

Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.
