Laser &Photonics Reviews, Volume 19, Issue 16, August 21, 2025.Fully exploiting the broad untapped terahertz spectrum necessitates extending the bandwidth of practical guided‐wave systems. This work introduces a substrateless quasi‐optical integration platform to meet this need. Classical optical principles going back to the time of Michelson are adapted to a planar, micro‐machined, monolithic‐silicon platform ...

Mitigating ingroup bias in regulatory firms: The role of inspector professionalism
Strategic Management Journal, Volume 46, Issue 8, Page 2019-2048, August 2025.Abstract This article adopts the lens of ingroup bias to study why regulatory firms tasked with enforcing regulatory compliance may underperform in their duties. We theorize that ingroup bias can lead regulatory agents to grant unwarranted trust to ingroup clients with whom they share salient characteristics, resulting in less stringent inspections for

Global Ecology and Biogeography, Volume 34, Issue 5, May 2025.ABSTRACT Aim Migratory birds are under threat by climate change. Successfully conserving them requires knowing which climatic factors drive changes in their migratory behaviour. Weather conditions may directly or indirectly affect the temporally disjointed life history stages of migratory birds, including the breeding, roosting and nonbreeding stages ...
