Travel Distances of Juvenile Fish Key to Better Conservation
Travel Distances Juvenile Fish Key Conservation
2017/7/20
Marine reserves—sections of the ocean where fishing is prohibited—promote coral reef sustainability by preventing overfishing and increasing fish abundance and diversity. But to be effective, they nee...
Down the rabbit hole: how electrons travel through exotic new material
Down the rabbit hole electrons travel exotic new material
2016/3/21
Researchers at Princeton University have observed a bizarre behavior in a strange new crystal that could hold the key for future electronic technologies. Unlike most materials in which elec...

Wave-equation-based travel-time seismic tomography – Part 2: Application to the 1992 Landers earthquake (Mw 7.3) area
High resolution 3 d P wave S wave crust velocity poisson's ratio model landers earthquake earthquake fault
2015/1/6
High-resolution 3-D P and S wave crustal velocity and Poisson's ratio models of the 1992 Landers earthquake (Mw 7.3) area are determined iteratively by a wave-equation-based travel-time seismic tomogr...
Wave-equation-based travel-time seismic tomography – Part 1: Method
Travel seismic tomography step by step linearity sensitivity to the kernel
2015/1/6
In this paper, we propose a wave-equation-based travel-time seismic tomography method with a detailed description of its step-by-step process. First, a linear relationship between the travel-time resi...
Study on the limitations of travel-time inversion applied to sub-basalt imaging
travel-time inversion sub-basalt imaging
2015/1/5
The difficulties of seismic imaging beneath high velocity structures are widely recognised. In this setting, theoretical analysis of synthetic wide-angle seismic reflection data indicate...
