A “Tech First” Approach to Foreign Policy? The Three Meanings of Tech Diplomacy
Global Policy, EarlyView.ABSTRACT Scholars have recently argued that international politics is plagued by instability as the world rapidly transitions from one crisis to another. This state of “Permacrisis,” or permanent crises between states, is driven by technological innovations which create new kinds of crises and drive competitions between adversarial states.

Effect of Wavy Wall on the Stability of Conical Hypersonic Boundary Layer at Small Angle of Attack
气体物理In order to obtain a high lift-drag ratio, hypersonic vehicles usually fly with a certain angle of attack. As a potential means to delay hypersonic boundary layer transition at 0° angle of attack, it is not clear how wavy wall affect the deve-lopment of ...

Evolving Geopolitics and Japan's Economic Security–Trade Nexus: ‘New Capitalism’ as a Balancing Act?
Global Policy, EarlyView.ABSTRACT Amid intensifying geopolitical tensions, governments increasingly perceive economic interdependence as a strategic vulnerability. Japan, situated geopolitically between two great powers—the United States and China—attempts to navigate geopolitics by prioritising economic security.

War as a Phenomenon of Inquiry in Management Studies
Journal 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 ...

Control Effectiveness of Vortex Generators in High‐Speed Flows in Off‐Design Conditions
PAMM, Volume 26, Issue 1, March 2026.ABSTRACT In aerospace transportation and propulsion systems, shock‐induced flow separation has strong detrimental effects on the aerodynamic behavior and performance. To alleviate these effects, separation control is necessary. A commonly pursued approach uses vortex generators (VG) of different design to increase the momentum transfer within the ...
