Hitting a bullet with a bullet: an analysis of colliding bullets using experimental data and explicit simulation methods [PDF]

Royal Society Open Science
A method to simultaneously fire and achieve a nose-to-nose collision of two bullets was created and compared to simulated results. This research focused on symmetric Taylor impact test techniques applied to 45-caliber Hornady 45177 full metal jacket (FMJ)

Carrier Mobility Enhancement in Two‐Dimensional Semiconductor

Interdisciplinary Materials, EarlyView.
In this review, we comprehensively describe recent progress in carrier mobility enhancement strategies for 2D semiconductor‐based field‐effect transistors considering the role of intrinsic defects, electrode contact interfaces, dielectric engineering, and lattice strain engineering.

Initial temperature influence on the powder speed combustion in the high pressure range

Vojnotehnički Glasnik, 1997
The initial temperature influence on the ballistics characteristics of powder is considered as well as the parameters of gas dynamics calculations. Analytical methods for thermal chemical and interior ballistics calculations are used.

Overcoming spectral limits of perovskite photodetectors for the infrared region

InfoScience, EarlyView.
Infrared (IR) photodetectors are vital for modern optoelectronics, but traditional inorganic semiconductors face limitations in cost, processing, and bandgap tunability. This review provides a summary of advanced strategies to extend metal halide perovskites into the IR region, categorizing approaches into intrinsic material engineering, physical ...

Dignity's Dilemma: Categorical Objections to Autonomous Weapons and Their Pacifist Entailments

Journal of Applied Philosophy, EarlyView.
ABSTRACT Dignity objections to autonomous weapon systems are prominent in contemporary military ethics, yet their theoretical foundations remain underexamined. This article reconstructs those foundations, showing what categorical dignity objections require to function as absolute prohibitions.

Stretch‐shortening cycle force–time and power–time waveform analysis indicates limitations of the contralateral limb benchmark in athletes with ACL injury

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Unilateral countermovement jump (CMJsingle) testing is commonly used after anterior cruciate ligament reconstruction (ACLR) to assess stretch‐shortening cycle (SSC) function and return‐to‐sport readiness. However, the impact of ACLR on contralateral limb SSC function is poorly understood, which may impact the utility of the ...

Discovering Shared Design Heritage for Semiconductor‐Based Gamma‐Ray Spectrometers: From CdTe to Metal Halide Perovskites

Laser &Photonics Reviews, EarlyView.
Decades of CdTe and CdZnTe gamma‐ray spectrometer development define core design principles for room‐temperature semiconductor detectors. This Review highlights how metal halide perovskites rapidly assimilate these principles, particularly through defect and compositional engineering strategies that establish favorable spectroscopic conditions for ...

Data‐Driven Insights into Hyperkinetic Disorders in Neurodevelopmental Syndromes and Epileptic Encephalopathies

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Childhood‐onset hyperkinetic movement disorders occur in a range of genetic conditions. Recently, there has been an increase in recognition of hyperkinetic movement disorders, mainly dystonia, chorea and dyskinesia, with monogenic conditions associated with neurodevelopmental delay (NDD) and also with developmental and epileptic ...

Asymmetric transferability of trait–environment relationships between native and exotic plant species in Singaporean forests differing in land‐use history

Oikos, EarlyView.
Functional traits allow ecologists to synthesise general rules of community assembly. In joint species distribution modelling, traits are increasingly used to explain species–environment relationships, with the intention of being able to generalise predictions to other species in other systems.
