Study of gunshot residues from Sintox® ammunition containing marking substances

open access: yesEgyptian Journal of Forensic Sciences, 2015
Two types of factory marked Sintox® ammunition were investigated from the composition of gunshot residue particles (GSR) and occurrence of marking substance points of view.

Predictions of Quantum Molecular Dynamical Model between incident energy 50 and 1000 MeV/Nucleon

open access: yesEPJ Web of Conferences, 2015
In the present work, the Quantum Molecular Dynamical (QMD) model is summarized as a useful tool for the incident energy range of 50 to 1000 MeV/nucleon in heavy-ion collisions.

Micro-motion feature extraction of narrow-band radar target based on ROMP

open access: yesThe Journal of Engineering, 2019
In this study, a new method based on regularised orthogonal matching pursuit (ROMP) decomposition is proposed to extract the feature of the ballistic target's rotating micro-motion.

Ballistic spin resonance [PDF]

open access: yesNature, 2009
The phenomenon of spin resonance has had far reaching influence since its discovery nearly 70 years ago. Electron spin resonance (ESR) driven by high frequency magnetic fields has informed our understanding of quantum mechanics, and finds application in fields as diverse as medicine and quantum information.

On exploiting nonparametric kernel-based probabilistic machine learning over the large compositional space of high entropy alloys for optimal nanoscale ballistics

open access: yesScientific Reports
The large compositional space of high entropy alloys (HEA) often presents significant challenges in comprehensively deducing the critical influence of atomic composition on their mechanical responses.

External ballistics of Pleistocene hand-thrown spears: experimental performance data and implications for human evolution

open access: yesScientific Reports, 2019
The appearance of weaponry - technology designed to kill - is a critical but poorly established threshold in human evolution. It is an important behavioural marker representing evolutionary changes in ecology, cognition, language and social behaviours ...
