Experimental and numerical study on CuO/ZnO-modified aramid fabric for ballistic and UV radiation protection

open access: yesPolymer Testing
Aramid fabrics are widely used in bulletproof armor because of their excellent mechanical properties. Previous studies have shown that ultraviolet radiation has a negative effect on the mechanical properties of aramid yarn, so improving the mechanical ...

Stim‐CODE: PNS and CNS Constraint Optimized Diffusion‐Encoding for Neuroimaging on 200 mT/m Whole‐Body Gradients

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Ultra‐high‐performance whole‐body MRI gradients (Gmax$$ {G}_{\mathrm{max}} $$ ≥$$ \ge $$ 200mT/m, Smax$$ {S}_{\mathrm{max}} $$ ≥$$ \ge $$ 200 T/m/s) can reduce echo times (TE) in diffusion‐weighted imaging (DWI), improving SNR. However, full hardware utilization is limited by cardiac (CNS) and peripheral (PNS) nerve stimulation ...

Dynamic Performance Enhancement of a High‐Agility Hypersonic Mechanical System via a Learning‐Augmented Robust Control Architecture

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The design of control systems for high‐agility mechanical systems operating in extreme environments is a significant challenge in nonlinear dynamics. This paper addresses the complex dynamic control problem of a hypersonic interceptor, modeled as a multi‐input multi‐output (MIMO) mechanical system characterized by strong aerodynamic cross ...

Shear thickening fluids and gels as reinforcement in ballistic vest: an update review

open access: yesJournal of Materials Research and Technology
Shear thickening fluids (STFs) and shear thickening gels (STGs) are smart materials that undergo a reversible, rapid transition from a low-viscosity state to a highly viscous or quasi-solid phase when subjected to shear rates above a critical threshold ...
