Raman‐Enabled Platicon Microcomb and Stokes Soliton in 4H‐SiC Microresonator
Laser &Photonics Reviews, EarlyView.We harness Raman gain in a silicon carbide microresonator to enable efficient platicon microcomb generation in the normal‐dispersion regime. The resulting platicon spans 1500–1700 nm with a pump‐to‐comb conversion efficiency up to 56%. Simultaneous excitation of a Stokes soliton within the same mode family further broadens the Raman–Kerr microcomb ...

PLANTS, PEOPLE, PLANET, EarlyView.A challenge for wild plant conservation is the rising incidence of plant pathogens that are difficult to interdict, contain and manage. Invasive, fast‐moving, broad‐spectrum pathogens impose societal costs through losses of intrinsically valuable wild biodiversity, ecosystem function, current and potential genetic and biological assets, culturally ...

Cultivating and embracing plurality in abductive inquiries within strategy research
Strategic Management Journal, EarlyView.Abstract Research Summary Abduction offers a mode of scientific inquiry that focuses on formulating explanations for unexplained phenomena. By building a bridge between philosophy of science and strategic management research, this article offers a pluralistic view of abduction, highlighting abductive triggers as the starting point in seeking ...

“Supernovae Ia Twins” in the Hubble Flow, and the Determination of H0
The Astrophysical JournalWe have applied our approach of using “supernovae (SNe) Ia twins” in the Hubble flow to obtain distances to SNe Ia at z > 0.015 and derive H _0 . Our results, taking a single step between the low- z domain and the Hubble flow, validate the three-rung ...

Beyond Manoeuvre Theory for European Defence
Global Policy, EarlyView.ABSTRACT This article contributes to the debate about European defence in the light of the Russo‐Ukraine war and growing doubts about US commitment to Europe. It argues that Europeans need to fundamentally relearn the ability to imagine military strategy from a European viewpoint.

Global Policy, EarlyView.ABSTRACT Recent shifts in European security have placed resilience at the center of deterrence and defense strategies. While resilience has traditionally been understood as the ability to withstand disruption and sustain military operations, there have been calls for a whole‐of‐society approach that strengthens societies against hybrid threats and ...

Towards Comprehensive Deterrence—Rethinking European Deterrence in the 21st Century
Global Policy, EarlyView.ABSTRACT Deterrence has re‐emerged as a central concept in international politics, but the dominant conception of it remains rooted in Cold War nuclear thinking. The paper argues that the concept of deterrence must be redefined to reflect the complexity of the current threat environment, in which hybrid, non‐military and societal threats increasingly ...
