Study on the Power‐Frequency Arc Extinction Characteristics of Semi‐Closed Short‐Gap Device
ABSTRACT Multi‐chamber arc‐extinguishing devices have a simple structure and excellent arc‐extinguishing performance; thus, they have attracted considerable attention as lightning protection devices. However, the structural parameters of different models of the aforementioned devices vary, leading to inconsistent protection levels; therefore, the arc ...

The First World War at Sea: Death, Commemoration and Cultural Remembrance
Abstract Despite the ever‐increasing body of work devoted to war memorials, national days of remembrance and the commemoration of the First World War in Britain, academic focus remains firmly on the commemoration of the First World War on land. Yet, while the number of people who died at sea paled in comparison to their counterparts on the battlefield ...

Blade shapes (leading‐edge geometry and thickness) in rotodynamic blood pumps were systematically evaluated. Thinner blades improve pump efficiency by reducing blockage effects, while neither blade thickness nor leading‐edge geometry shows clear hemocompatibility benefits. Overall, blade shape has a limited impact on hemocompatibility, indicating it is

This study utilized an extensive optimization involving n = 540 design of experiments to produce a superior drainage cannula design. Compared to the clinically used Maquet model, our optimized design demonstrated reduced blood stagnation volumes, increased cannula tip velocities, and higher upper body drainage, potentially minimizing risk of thrombosis

Hierarchical Differentiable Fluid Simulation
We introduce a two‐step algorithm that significantly reduces memory usage for solving control problems using differentiable fluid simulation techniques: our method first optimizes for bulk forces at reduced resolution, then refines local details over sub‐domains while maintaining differentiability. In trading runtime for memory, it enables optimization

Primal SPH Solver for Strongly Coupled Multiphase Simulations with High Density Ratios
Abstract In recent years, the Smoothed Particle Hydrodynamics (SPH) approach has been increasingly used for multiphase simulations involving interactions between diverse materials. A critical component of an SPH simulator is the pressure solver, which not only facilitates the simulation of compressible or incompressible fluids but also handles contact ...

Immobilized CuCl2/TiO2 photocatalysts for the selective oxidation of benzyl alcohol to benzaldehyde
The photocatalytic aerobic oxidation of benzyl alcohol to benzaldehyde was investigated using free and alginate‐immobilized CuCl2 and/or TiO2 (P25) catalysts under UV irradiation. Immobilization enabled catalyst recovery and maintained high benzaldehyde selectivity but led to reduced activity due to internal oxygen diffusion limitations, which were ...
