SUMMARY We construct a high-resolution shallow 3-D seismic model in the top 10 km of upper crust continental China, with constraints P polarization, Rayleigh wave ellipticity and receiver function obtained from records 3848 stations. Our has spatial resolution 0.6–1.2° north–south belt trans-north China orogen, 1–2° rest (except Tarim basin southwest Tibet). The exhibits low velocity anomalies deposits major sedimentary basins high crustal bedrocks young orogenic belts old tectonic blocks....
Abstract The Shanxi rift is located in the central part of North China Craton (NCC). With strong tectonic deformation and intense seismic activity, its crust‐mantle deep structure have always attracted wide attention. Using teleseismic events observed a dense network 610 temporary 127 permanent stations NCC, we obtained S wave velocity structures by joint inversion method receiver functions surface dispersion data. Our results show that crust thickens northern (41 km) thins southern (35 km)....
Abstract We construct a high‐resolution Pn ‐velocity model in continental China through new tomographic scheme simultaneously inverting event epicenter location and accurately accounting for the propagation effects of irregular crustal thickness variation. The inversion integrates combined data set 32,427 absolute travel times 62,431 interstation differential manually picked from recordings 2,989 stations around China, yielding spatial resolutions ranging 0.75° × 0.75°–3° 3°.

Research on heterogeneous combat networks (HCNs) has attracted considerable interest in the military field since they can provide useful insights into provision of decision-making assistance. The characteristics high-operational-capability HCNs are not well studied, which limits ability to construct a better network. To fill this gap, an integrated methodology named genetic algorithm-based high-capability HCN analysis (GAHCA) is presented elucidate networks. In GAHCA, improved algorithm...
Abstract The Yin‐He Global Spectral Model (YHGSM) is a dry‐mass conserving hydrostatic global spectral model, relying on transforms to compute horizontal derivatives. We present an extension of YHGSM core named YHGSM‐FVM which uses second‐order finite‐volume method (FVM) the derivatives in grid‐point space instead approach. With this approach, computational efficiency model improved since part superseded by FVM only needs local data and demand lower. More importantly, still solving Helmholtz...
With the development of computer technology, overlapping computation with communication has been continuously developed and widely applied in process from single machine to supercomputer. The degree parallelization is getting higher higher, data volume between nodes larger larger. Communication overhead becomes an important factor affecting parallel computing. way solve excessive This paper first introduces history communication, including hardware optimization compiler upgrade task...
<p>North China Craton is the oldest craton in world. It contains eastern, central and western part. Shanxi rift Taihang mountain contribute With strong tectonic deformation intense seismic activity, its crust-mantle deep structure have always been highly concerned. In recent years, Earthquake Administration has deployed a dense temporary array North China. permanent stations, we obtained S-wave velocity by using joint inversion of receiver function surface wave dispersion.
