Landmarking for Navigational Streaming of Stored High-Dimensional Media

Pascal Frossard, Yuan Yuan

Modern media data such as 360 degrees videos and light field (LF) images are typically captured in much higher dimensions than the observers' visual displays. To efficiently browse high-dimensional media, a navigational streaming model is considered: a cli ...

Evidence for D0-D̄0 mixing

Mingkui Wang, Olivier Schneider, Chao Wang, Lei Zhang, Aurelio Bay, Vladislav Balagura, Stewart Cole, Jean Wicht, Sun Hee Kim, Yuan Yuan

We observe evidence for D0-D̄0 mixing by measuring the difference in the apparent lifetime when a D0 meson decays to the CP eigenstates K+K- and π+π- and when it decays to the final state K-π+. We find the relative difference of the lifetimes yCP to be [1. ...
