Vertical and horizontal component velocity seismograms from the CNSN seismic network of southeastern Canada and from the KMA and KIGAM networks of Korea are used for this study of high frequency ground motion scaling. I analyzed a data set consisting of 4646 three component seismograms for southeastern Canada, distances km, and 2701 three component waveforms for Korea, distances 600 km. I perfo...

N-propylsalicylidene based on silica as ion exchanger (IE) was used for the separation by complexation of Mn2+, Co2+, Ni2+, Cu2+, Hg2+, Cr3+, Fe3+, and UO22+ from their parent solutions. IE and its metal complexes are characterized by elemental analysis, electronic and infrared spectra, in addition to thermal analysis in atmospheric pressure. The mode of chelation and the proposed geometric str...

Dynamic wetting problems are fundamental to understanding the interaction between liquids and solids. Even in a superficially simple experimental situation, such as a droplet spreading over a dry surface, the result may depend not only on the liquid properties but also strongly on the substrate-surface properties; even for macroscopically smooth surfaces, the microscopic geometrical roughness c...

Abstract A global study of subduction zone dynamics indicates that the thermal structure overriding plate may control arc location. fast convergence rate and a steep slab dip bring hotter mantle further into wedge corner, forming volcanoes closer to trench. Separately, laboratory numerical experiments showed development back‐arc spreading center (BASC) is driven by migration subducting hinge, e...

In this paper we study the household-structure SIS epidemic spreading on general complex networks. The household structure gives us the way to distinguish inner and the outer infection rate. Unlike household-structure models on homogenous networks, such as regular and random networks, here we consider heterogeneous networks with arbitrary degree distribution p(k). First we introduce the epidemi...

The measurement of regional attenuation Q can produce method dependent results. The discrepancies among methods are due to differing parameterizations (e.g., geometrical spreading rates), employed data sets (e.g., choice of path lengths and sources), and methodologies themselves (e.g., measurement in the frequency or time domain). We apply the coda normalization (CN), two-station (TS), reverse ...
