Almost 75 Years Ago The #USA Ran A Dirty #RegimeChange Through #Iran At Behest Of

The U.S. helped oust Iran’s government in 1953. Here’s what happened.
The U.S. has not publicly called for regime change in the current Israel-Iran conflict, but over 70 years ago, it played a key role in ousting Tehran’s government.

Upper Bound on Quantum Fisher Information in Pseudo-Hermitian Systems
Non-Hermitian systems have attracted considerable interest over the last few decades due to their unique spectral and dynamical properties not encountered in Hermitian counterparts. An intensely debated question is whether non-Hermitian systems, described by pseudo-Hermitian Hamiltonians with real spectra, can offer enhanced sensitivity for parameter estimation when they are operated at or close to exceptional points. However, much of the current analysis and conclusions are based on mathematic…

K2 observations of five pulsating subdwarf B stars with white dwarf companions
We report seismic analyses of five pulsating subdwarf B (sdBV) stars observed during Kepler's K2 mission, each with a white dwarf companion. We find three of the five to be g-mode-dominated hybrid pulsators. For the other two, we only detect g modes. We determine rotation periods from frequency multiplets for four stars and each rotates subsynchronously to its binary period, including PG 0101+039 and PG 0902+124 both with binary periods near 0.57 days and spin periods near 9 days. We detect fre…

GIC--Related Observations During the May 2024 Geomagnetic Storm in the United States
The May 2024 geomagnetic storm was one of the most severe in the past twenty years. Understanding how large geomagnetic disturbances (GMDs) impact geomagnetically induced currents (GICs) within power grid networks is key to ensuring their resilience. We have assembled and synthesized a large and diverse set of GMD-related data, compared model predictions with measurements, and identified empirical relationships for GICs in the contiguous United States for this storm. Measurement data include …

Magnetic excitations from the hexagonal spin clusters in the S = 1/2 distorted honeycomb lattice antiferromagnet Cu2(pymca)3(ClO4)
Cu2(pymca)3(ClO4) (pymca: pyrimidine-2-carboxylate) consists of a slightly distorted honeycomb lattice of Cu2+ spins, which shows no long-range magnetic order down to 0.6 K. A magnetization study revealed 1/3 and 2/3 plateau phases [A. Okutani et al., J. Phys. Soc. Jpn. 88, 013703 (2019)], which is not expected for regular honeycomb antiferromagnets. Inelastic neutron scattering experiments were performed using a powder sample to investigate the exchange interactions of this material. The spin …
