Influence of Incident Shock on Fuel Mixing in Scramjet
Applied SciencesDuring 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 ...

Universities as the Next Counterintelligence Battleground in Geopolitical Contests
Global 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 ...

Risk Scenarios for European Rearmament
Global Policy, EarlyView.ABSTRACT Since Russia's invasion of Ukraine in 2022, the European Union has launched a flurry of initiatives to ramp up European defence spending. Efforts to bolster European defence have further intensified in response to the United States' increasingly hostile stance towards its erstwhile European allies.

The Continuity and Rupture of the ‘New Washington Consensus’: From Biden to Trump 2.0
Global Policy, EarlyView.ABSTRACT The ‘New Washington Consensus’ (NWC) represents a major intellectual shift in the US approach to global economic governance. However, the NWC has never been subject to systematic academic critique. With Trump's return to the White House ushering in a new era of US trade policy, the NWC is widely considered to be politically irrelevant in the ...
