Elongated magma plumbing system beneath the Coso volcanic field, California, constrained by seismic reflection tomography by Wang, Dongdong, Wu, Shucheng, Li, Tianjue, Tong, Ping, Gao, Yongxin

“…For the first time, we develop a high-resolution crustal P-wave velocity model for the Coso-Ridgecrest region by jointly inverting 137,992 first P and 8,636 PmP travel-time data using an eikonal equation-based seismic reflection tomography method. More than half of the PmP travel times are picked from earthquakes after the 2019 Mw 7.1 Ridgecrest earthquake. …”

The impact of photopigment bleaching on the human rod photoreceptor subretinal space measured via optical coherence tomography by Messner, Alina, Dos Santos, Valentin Aranha, Puchner, Stefan, Stegmann, Hannes, Schlatter, Andreas, Schmidl, Doreen, Leitgeb, Rainer, Schmetterer, Leopold, Werkmeister, René M.

“…The purpose of this study was to investigate rod photopigment bleaching-driven intrinsic optical signals (IOS) in the human outer retina and its measurement repeatability based on a commercial optical coherence tomography (OCT) platform. METHODS. The optical path length of the rod photoreceptor subretinal space (SRS), that is, the distance between signal bands of rod outer segment tips and retinal pigment epithelium, was measured in 15 healthy subjects in ambient light and during a long-duration bleaching white-light exposure. …”
