Late Mesozoic granitoids are widely emplaced in the Qinling Orogen on southern margin of North China Craton (NCC), and can provide important clues regional geodynamic setting. The Jurassic Laoniushan granitic pluton is located western end NCC margin. Zircon U–Pb dating for granodiorite, quartz diorite, biotite monzogranite yielded 152.5 ± 1.6 Ma, 148.7 1.2 149–146 respectively. Compilation single zircon ages revealed magmatic peaks at ca. 146, 152, 163 suggesting multiphase magmatism. These...

Improving the quality of wavefront shaping (WFS) is a major problem anti-scattering optical information transmission in perturbation environment. To tackle this issue, we propose simple and robust method, named Point Guard algorithm (PGA), to manipulate interference by encoding digital micromirror device (DMD). The PGA method inspired movement strategies (PG) professional basketball association. Compared with most popular genetic (GA), proposed has stronger anti-perturbation capacity. In...
