The stochastic gravitational-wave background (SGWB) created by astrophysical sources in the nearby Universe is likely to be anisotropic. Upper limits on SGWB anisotropy have been produced for all major data-taking runs ground-based laser interferometric detectors. However, due challenges involved numerically inverting pixel-to-pixel noise covariance matrix, which necessary setting upper limits,...

Background: Breeding soundness evaluation (BSE) is the primary assessment for determining reproductive potential of male animals. This method, however, cannot be used to evaluate semen frequently or to predict future semen quality. Computerized analysis of ultrasonographic images provides information on histophysiological changes in male reproductive organs.We hypothesized that: 1. semen parame...

Quantum diamond magnetometers using lock-in detection have successfully detected weak bio-magnetic fields from neurons, a live mammalian muscle, and mouse heart. This opens up the possibility of quantum visualizing microscopic distributions fields. Here, we demonstrate lock-in-based widefield microscopy, achieving mean volume-normalized per-pixel sensitivity 43.9 nTμm1.5/Hz0.5. We optimize by i...
