Determination of performance parameters of an equilateral triangular cavity resonator

In this article, a set of closed form expressions is proposed to compute the resonant frequency, unloaded quality factor, equivalent circuit components of cavity, coupling capacitance, external quality factor, input resistance at resonance, input impedance and loaded quality fact...

The chromomagnetic moment of a heavy quark with hyperasymptotic precision

A bstract We determine the normalization of the leading infrared renormalon of the chromomagnetic moment of a heavy quark. Estimates of higher order coefficients of the perturbative series are given. We compute the hyperfine splitting of the B and D mesons for the ground state wi...

J-PAS: Semisupervised Sim-to-Obs Transfer for Robust Star–Galaxy–Quasar Classification

Abstract Modern astrophysics and cosmology increasingly rely on simulations and cross-survey analyses, yet differences in instrumentation, calibration, and modeling introduce distribution mismatches between simulated and observed datasets (domain shift). This occurs when the join...
