Crash Behavior of DP800–DP1000 Advanced High‐Strength Steel’s Dissimilar Resistance Spot Welded Joints Under Quasi‐static and High Strain Rates

open access: yessteel research international, EarlyView.
The high‐strain‐rate behavior of resistance spot‐welded DP800–DP1000 joints is investigated. Results show that microstructural gradients across BM–HAZ–FZ govern hardness, strain rate sensitivity, and failure modes. While strength increases with strain rate, energy absorption is controlled by ductility, with DP800–DP800 joints showing superior ...

How many shots are enough? Optimizing precision measurements when testing lead‐free ammunition

open access: yesWildlife Biology, EarlyView.
Growing concern about lead exposure in scavenging wildlife and the consumers of game meat has increased interest in evaluating the performance of lead‐free rifle ammunition. Testing both accuracy and precision helps ensure reliable shot placement while reducing the risk of non‐fatal woundings.

Europium‐ and dysprosium‐modified strontium aluminate: A luminescent marker system for enhanced gunshot residue detection

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract Forensic ballistics is essential in analyzing evidence from firearm use in criminal investigations, with gunshot residue (GSR) detection providing key information about the firearm and shooting conditions. Traditional methods like spectroscopy and scanning electron microscopy (SEM) have limitations in sensitivity, cost, and accessibility ...

Sharp force trauma analysis without animal bones: A proposal for sustainable and ethical bone proxies

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract Sharp force trauma has been the leading cause of homicide in England and Wales for more than a decade. Experimental research on sharp force trauma frequently relies on animal bone as a substitute for human remains, yet their ethical acceptability and comparability to human bone remain contested.

The Dual‐Use Conundrum of the Lisbon Treaty Regarding Space Governance: Solutions Through International Legal Interpretation?

open access: yesGlobal Policy, EarlyView.
ABSTRACT An inherent divide features within the Lisbon Treaty between civilian and military/security competences; something previously more obvious via the ‘pillar system's’ separations. This division follows the Member States (MS) (natural) protection of their military/defence autonomy; their core sovereign powers.

HSPICE implementation of a numerically efficient model of CNT transistor

open access: yes
This paper presents the algorithms of an implementation of a numerically efficient carbon nanotube transistor (CNT) model in HSPICE. The model is derived from cubic spline non-linear approximation of the non-equilibrium mobile charge density.

The Unintended Consequences of German Deterrence

open access: yesGlobal 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.
