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

Polymer 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 ...

Stochastic Locomotion Emerging From Body–Environment Interactions in a Mexican Jumping Bean–Inspired Robot

Advanced Intelligent Systems, EarlyView.
Inspired by the Mexican jumping bean, this study presents a centimeter‐scale, electronics‐free robot that merges principles from both the animal and plant kingdoms. A thermo‐responsive actuator mimicking larval motion, enclosed within a uniquely shaped plant‐seed‐inspired shell, generates jumping, rolling, flipping, sliding, and climbing through ...

Effect of ballistic exercise program on shoulder dynamic stability, throwing performance and shoulder strength among university level female cricket bowlers

Bangabandhu Sheikh Mujib Medical University Journal
Background: Bowling in cricket is a ballistic movement requiring rapid force generation. The Thrower's Ten and Ballistic Six programs are widely used for overhead athletes to enhance shoulder performance. Unlike general ballistic exercises, the Ballistic

Thermoelectric Response and Field‐Induced Figure of Merit in Fluorine–Doped Carbon Nanotube Using the Lorenz Number

Advanced Physics Research, EarlyView.
Thermoelectric conductivity decreases nonlinearly with increasing temperature for all investigated band‐gap values. Higher energy splitting yields lower conductivity, while smaller gaps maintain superior carrier transport. Peak response occurs at low temperature, followed by gradual saturation at elevated temperatures.

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

The Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

The Tendon‐to‐Bone Seam: A Transtendinous Approach to Rotator Cuff Repair

Arthroscopy Techniques, EarlyView.
Abstract This technique article describes the tendon‐to‐bone seam technique, a knotless, transtendinous approach to arthroscopic rotator cuff repair. The technique employs a single‐use deployment device preloaded with multiple PEEK anchors interconnected with a single polyethylene #2 suture, enabling the surgeon to create a continuous “seam” of ...

Maximizing Neurovascular Outcomes of Facial Transplantation: A Comprehensive Review

Clinical Anatomy, EarlyView.
ABSTRACT Facial transplantation is a division of reconstructive surgery which aims to improve the function and appearance of a face that has endured severe disfigurement. Currently, the face transplant procedure uses allogenic tissue, harvested from a brain‐dead donor, to replace damaged facial components.
