Inspired by quantum gravity frameworks predicting Planck-scale deviations from Lorentz invariance, we probe Lorentz symmetry violation via modified dispersion relations ω|k|. Departing from conventional approaches, we employ an Unruh-DeWitt detector to probe energy-dependent modifications to the dis...

Accurate estimation of heading direction from optic flow is a crucial aspect of human spatial perception. Previous psychophysical studies have shown that humans are typically biased in their heading estimates, but the reported results are inconsistent. While some studies found that humans generally...

Abstract The kuruma shrimp (Marsupenaeus japonicus) is a highly fecund marine aquaculture species with substantial variance in reproductive success. These traits may lead to genetic diversity loss and inbreeding, particularly under mass selection programs. In this study, we assessed genetic diversit...
