Influence of Incident Shock on Fuel Mixing in Scramjet

open access: yesApplied Sciences
During the operation of hypersonic vehicles, a reciprocal coupling effect is manifested between the inlet and the combustion chamber. This results in an unavoidable non-uniformity of conditions at the combustion chamber’s entrance, which, in turn ...

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.

Universities as the Next Counterintelligence Battleground in Geopolitical Contests

open access: yesGlobal Policy, EarlyView.
ABSTRACT Globally, universities are increasingly becoming the target of foreign national security actors, engaging in espionage, sabotage, foreign interference and intellectual property theft. Despite that, there has been no examination of the utilisation of counterintelligence approaches by universities to the threats they face from the subordination ...

War as a Phenomenon of Inquiry in Management Studies

open access: yesJournal of Management Studies, EarlyView.
Abstract We argue that war as a phenomenon deserves more focused attention in management. First, we highlight why war is an important and relevant area of inquiry for management scholars. We then integrate scattered conversations on war in management studies into a framework structured around three building blocks – (a) the nature of war from an ...

Propagation of Elastic Waves in a One-Dimensional High Aspect Ratio Nanoridge Phononic Crystal

open access: yesApplied Sciences, 2018
We investigate the propagation of elastic waves in a one-dimensional (1D) phononic crystal constituted by high aspect ratio epoxy nanoridges that have been deposited at the surface of a glass substrate.

Optimizing Cf/ZrB2–SiC Composites for Aerospace TPS via Density‐Normalized Performance

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 4, August 2026.
ABSTRACT In this study, the mechanical performance of ZrB2–SiC‐based carbon fiber‐reinforced composites was evaluated using a design‐oriented framework, focusing on the effects of fiber architecture (long/short fibers) and rheology modifier (RM) addition.
