Between Hedging and Bandwagoning: E3 and Iran's Nuclear Program From the JCPOA to the 2026 “Ramadan War”

Global Policy, EarlyView.
ABSTRACT This article examines the evolution of the European Troika's narratives on Iran's nuclear program, from the aftermath of the JCPOA to the 2026 “Ramadan War.” Drawing on an analysis of 55 official statements by E3 leaders and diplomats, the study traces how the E3 shifted between a posture of normative hedging and one of bandwagoning.

Wave Tracing: Generalizing The Path Integral To Wave Optics

Computer Graphics Forum, EarlyView.
Abstract Modeling the wave nature of light and the propagation and diffraction of electromagnetic fields is crucial for the accurate simulation of many phenomena, yet wave simulations are significantly more computationally complex than classical ray‐based models.

Adaptive Optical Layers: Efficient Tall Cell Grids for Liquid Simulation

Computer Graphics Forum, EarlyView.
Abstract Tall cell grids have been proposed as an efficient approach to accelerate large‐scale liquid simulation. In this framework, regions near the liquid surface are discretized with regular grids, while regions farther away are represented by elongated rectangular cells.

Bolide Light Curve Systematics from 75 Recovered Meteorites

Meteoritics &Planetary Science, EarlyView.
Abstract How does the energy deposition profile (light curve), deceleration, and penetration depth in Earth's atmosphere depend on asteroid composition and meteorite type? Here, we present the light curve and velocity profile of 75 bolides from camera‐documented meteorite falls.

The effect of muzzle blast wave on light screen in external ballistic measurement

Frontiers in Physics
IntroductionIn 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,

Geophysical update of the diameter of the Zhamanshin impact structure, Kazakhstan

Meteoritics &Planetary Science, EarlyView.
Abstract The rim of the 0.9‐Ma‐old Zhamanshin impact crater in Kazakhstan is considered to be almost completely exposed via a series of hills surrounding a central flat area, indicating an apparent diameter of 14 km. This would make Zhamanshin the second largest impact crater of the Quaternary period. However, the overall geometry of these hills is not

Isometric training at longer muscle–tendon complex lengths: A potential countermeasure to impaired neuro‐muscle–tendon function during space travel

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 ...
