Seed pretreatment length when producing seeds for restoration may impact seed dormancy in offspring
Restoration Ecology, EarlyView.Abstract Introduction Seed dormancy regulates germination timing to improve seedling survival. Many temperate species produce physiologically dormant seeds, requiring winter conditions (i.e. moist‐cold stratification) to overcome dormancy. Exposing seeds to suboptimal stratification lengths for restoration may alter genetic diversity and/or ...

Experimental Physiology, EarlyView.Abstract Manned space exploration to distant destinations, including Mars, continues to be an aspiration of humankind. Space travel does, however, present many challenges to the body, amongst which adaptation to microgravity is perhaps the largest. For instance, both short and long manned spaceflight missions have shown substantial deleterious effects ...

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.

Validation of Intravoxel Incoherent Motion MRI Using Perfused Explanted Human Livers
Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2291-2304, April 2026.ABSTRACT Purpose Evaluate the feasibility of using perfused explanted human livers for validating intravoxel incoherent motion (IVIM). Methods Eight (n = 8) explanted livers from deceased donors were obtained. The portal vein and hepatic artery of each explanted liver were connected to a perfusion system.

The effect of muzzle blast wave on light screen in external ballistic measurement
Frontiers in PhysicsIntroductionIn measuring initial velocity, light screen detectors (LSD) are positioned closer to the muzzle. The light screen of the LSD can be affected by the muzzle blast wave (MBW), resulting in an inaccurate initial velocity.MethodsA method for analyzing the effect of the MBW as it passes through the light screen is proposed in this article. First,
