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 ...

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 ...

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

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 ...
