Advanced Photonics Research, Volume 7, Issue 7, July 2026.An ENZ metamaterial slab enables near‐field coupling suppression in dual circularly polarized stacked patch antennas while preserving radiation performance. The near‐zero‐index environment attenuates the transmission of parasitic coupling components between adjacent radiators, distinct from conventional current‐cancelation or port‐compensation ...

When does category spanning hurt or help producers?
Strategic Management Journal, Volume 47, Issue 7, Page 1907-1934, July 2026.Abstract Research Summary Scholars have theorized many factors shaping whether category spanning helps or hurts producers. We first synthesize evidence by meta‐analyzing 25 years of empirical research, which reveals a null effect of spanning on average, yet with significant subsample heterogeneity. To unpack it, we theorize and find that spanning hurts

American Journal of Political Science, Volume 70, Issue 3, Page 925-945, July 2026.Abstract How can defense alliances reap the efficiency gains of working together when coordination and opportunism costs are high? Although specializing as part of a collective comes with economic and functional benefits, states must bargain over the distribution of those gains and ensure the costs of collective action are minimized.

Killer Whales in the Central Tropical Pacific: Occurrence, Resightings, Morphology, and Acoustics
Marine Mammal Science, Volume 42, Issue 3, July 2026.ABSTRACT Compared to their well‐studied coastal temperate counterparts, killer whales (Orcinus orca) in tropical‐subtropical and oceanic areas are under‐documented. We used sighting, photo‐identification, and acoustic data of killer whales in the central tropical Pacific (CTP), collected from multiple platforms between 2002 and 2023, to assess their ...

Nanophotonics, Volume 15, Issue 12, 25 June 2026.Traditional metasurfaces suffer from the drawbacks of pure microwave absorption and low IR emissivity stealth, namely failing to match complex ambient backgrounds with varying IR emissivity and generating excess heat accumulation (enhanced IR thermal radiation).
