US‐Japan Alliance: Emmeshing Bilateralism Into Broader Multilateralism
Asia &the Pacific Policy Studies, Volume 13, Issue 2, May 2026.ABSTRACT In the 21st Century, geopolitical confrontation between the Eurasian continental powers and the sea powers works to divide Asia. The US‐Japan alliance has transformed itself from Japanʼs asymmetrical security dependence of the Cold War period into a mutual and more integrated partnership today.

High‐Velocity Ballistic Impact Performance of FFF Printed PEEK With Different Infill Patterns
Macromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.This study examines 3D printed PEEK under Izod, quasi‐static, and high‐velocity impact. Hexagonal infill shows the highest Izod impact strength and superior quasi‐static energy absorption. However, under ballistic impact, all patterns behave similarly, indicating performance depends on infill at low velocity, but on intrinsic material properties at ...

Filling a Gap in Materials Mechanics: Nanoindentation at High Constant Strain Rates up to 105 s−1
Small, Volume 22, Issue 28, 18 May 2026.A piezoelectric nanoindentation platform enables constant strain‐rate testing up to 105 s−1, extending experimental capabilities to extreme deformation regimes. Distinct hardness upturns are revealed across crystalline and amorphous materials, verified as intrinsic responses through quasi‐static reloading.

Constitutional Bait and Switch: Executive Reinterpretation of Arms Control Treaties [PDF]
, 1989 A new constitutional crisis has been thrust upon the American body politic. The crisis arises from a dispute concerning the allocation of legal authority for the interpretation, and especially for the reinterpretation, of international agreements. Once a

Modeling the Delivery of Mercury's Polar Ice by a Volatile‐Rich Impact
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Permanently shadowed regions near Mercury's poles are thought to harbor significant deposits of water ice, the origin of which remains to be conclusively determined. One leading hypothesis is that most of the water observed today may have been delivered by a relatively recent, volatile‐rich impact comparable in scale and age to that which ...
