Machine learning prediction of UHPC creep coefficient using optimized extremely randomized trees

The increased mechanics, durability, and affordability of ultra-high-performance concrete (UHPC) with regular Coarse Aggregate (CA) make it promising. machine learning (ML) was used to study UHPC Creep. Using feature significance analysis, the Aggregate-To-Cement Ratio (AG/C), co...

Cross-sectional assessment of cerebral hemodynamics in individuals with type 2 diabetes and orthostatic hypotension

This cross-sectional study investigated the cerebral hemodynamics of patients with type 2 diabetes (T2DM) with varying orthostatic hypotension (OH) statuses. Using transcranial Doppler (TCD), we assessed cerebral blood flow velocities (CBFv) and pulsatility index (PI) during a su...
