Investigation of the Inverse Magnus Effect on a Rotating Sphere in Hypersonic Rarefied Flow

Applied Sciences
Explorations involving long-endurance and maneuvering flights in the upper atmosphere, as well as research on atmospheric entries of space debris or asteroids, call for a full understanding of hypersonic rarefied flows.

Artefact‐aware Brillouin microscopy framework for root mechanical phenotyping

Journal of Microscopy, EarlyView.
Abstract Plant roots continuously sense and respond to the mechanical signals of their growth environment: root cap function, mucilage secretion, and hormonal regulation jointly adapt root tip mechanics, shaping whether roots penetrate compacted layers or reorient around obstacles. Most current measurements of root mechanical properties require removal

Multi-Objective RANS Aerodynamic Optimization of a Hypersonic Intake Ramp at Mach 5

Energies, 2022
The work describes a systematic optimization strategy for designing hypersonic inlet intakes. A Reynolds-averaged Navier-Stokes database is mined using genetic algorithms to develop ideal designs for a priori defined targets.

Post‐flight assessment of the OSIRIS‐REx Sample Return Capsule (SRC) for organic and other potential contaminants

Meteoritics &Planetary Science, EarlyView.
Abstract Regolith samples from the carbonaceous asteroid Bennu were stowed and delivered to Earth in the OSIRIS‐REx spacecraft's Sample Return Capsule (SRC). We applied multiple analytical techniques to study the components of the post‐flight SRC, with a focus on assessing the conditions and any contaminants to which the Bennu samples were exposed ...

Universities as the Next Counterintelligence Battleground in Geopolitical Contests

Global Policy, Volume 17, Issue 4, Page 734-743, September 2026.
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 ...

Application of surrogate models to stability analysis and transition prediction in hypersonic flows

Advances in Aerodynamics, 2022
To increase the efficiency and robustness of stability-based transition prediction in flow simulations, simplified methods are introduced to substitute direct stability analyses for rapid disturbance growth prediction.

War as a Phenomenon of Inquiry in Management Studies

Journal of Management Studies, Volume 63, Issue 6, Page 2363-2397, September 2026.
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 ...
