Impact of Concave and Convex Solid Surfaces By Liquid-Like Projectiles
A theoretical and experimental investigation of the normal impact of a flat-ended liquid slug onto ductile cylindrical solid targets is presented. The liquid slug is simulated by wax which is known to behave as a liquid in high speed impact situations ...

Abstract Objective Psychological stress is commonly reported as a seizure precipitant in epilepsy, yet evidence from major crises remains limited and inconsistent. We examined whether the October 2023 Israel–Hamas conflict affected acute seizure‐related healthcare utilization among adults with epilepsy. Methods We conducted a retrospective cohort study

Modeling of Dual-Spinning Projectile with Canard and Trajectory Filtering
The article establishes a seven-degree-of-freedom projectile trajectory model for a new type of spinning projectile. Based on this model, a numerical analysis is performed on the ballistic characteristics of the projectile, and the trajectory of the dual-
