Thermal persistence and physicochemical modification of inorganic gunshot residue (IGSR)

Journal of Forensic Sciences, EarlyView.
Abstract In the medicolegal context, GSR analysis plays a key role in clarifying the dynamics of firearm‐related deaths, including lesion identification and firing distance determination. However, postmortem alterations of the body, such as thermal exposure, may influence the analysis of lesions and complicate interpretation.

A Thoracic Mechanism of Mild Traumatic Brain Injury Due to Blast Pressure Waves [PDF]

, 2008
The mechanisms by which blast pressure waves cause mild to moderate traumatic brain injury (mTBI) are an open question. Possibilities include acceleration of the head, direct passage of the blast wave via the cranium, and propagation of the blast wave to

Region‐of‐interest geometry optimization for shooting‐distance estimation from flash‐pulse infrared thermography of gunshot residue on textile targets

Journal of Forensic Sciences, EarlyView.
Abstract Shooting‐distance estimation from gunshot‐residue (GSR) patterns on textiles is affected by substrate properties, residue distribution, and region‐of‐interest (ROI) definition. This study evaluated how ROI geometry influences muzzle‐to‐target distance regression from flash‐pulse infrared thermography of GSR‐related thermal patterns.

Benjamin Robins's New Principles of Gunnery and the Response From the British Mathematical, Educational, and Military World of the Mid‐Eighteenth Century

Journal for Eighteenth-Century Studies, EarlyView.
Abstract This article analyses to what degree Benjamin Robins's discoveries in his book New Principles of Gunnery, 1742, affected the British mathematical, military, and educational world of the mid‐eighteenth century. While it drew praise and critique from Europe, especially from the notable mathematician Leonhard Euler, his mathematical theories were

The Unintended Consequences of German Deterrence

Global Policy, EarlyView.
ABSTRACT Germany's evolving deterrence posture boils down to continued participation in NATO nuclear sharing and an ambitious conventional rearmament program. Due to its non‐nuclear status and a result of decades of underinvestment, Germany prioritizes modern conventional weapons.

Moderate is the New Black: Shifts and Intersections in Saudi Arabia's Domestic and Foreign Policy

Global Policy, EarlyView.
ABSTRACT The Kingdom of Saudi Arabia (KSA) is undergoing a period of intense changes. Its current stage of transformation has been led by Prince Mohammed bin Salman (MbS) since 2015, seeking to turn the Kingdom into a story of successful governance and one of the leading powers in the Middle East. In hardly understood yet very consequential ways, KSA's

Wave Tracing: Generalizing The Path Integral To Wave Optics

Computer Graphics Forum, EarlyView.
Abstract Modeling the wave nature of light and the propagation and diffraction of electromagnetic fields is crucial for the accurate simulation of many phenomena, yet wave simulations are significantly more computationally complex than classical ray‐based models.
