Abstract Pore structural characteristics and methane adsorption capacity are two significant aspects affecting shale gas potential, but the impact of deposition burial processes on these is not clear. Hence, samples Taiyuan Formation deposited continuously experienced multi-stage tectonic uplift in Fuyang-Bozhou area Southern North China Basin were collected this study. Based total organic carb...

The bonding of glass wafers to aluminum foils in multi-layer assemblies was investigated by the fieldassisted diffusion bonding process. Bonding was effected at temperatures in the range 350–450 C and with an applied voltage in the range 400–700 V under a pressure of 0.05 MPa. The experimental parameters of voltage and temperature were the main factors in influencing the ionic current leading t...

Thomassen conjectured that every 4-connected line graph is Hamiltonian. Chen and Lai (Combinatorics and Graph Theory, vol 95, World Scientific, Singapore, pp 53–69; Conjecture 8.6 of 1995) conjectured that every 3-edge connected and essentially 6-edge connected graph is collapsible. Denote D3(G) the set of vertices of degree 3 of graph G. For e = uv ∈ E(G), define d(e) = d(u)+ d(v)− 2 the edge ...

The efficient sharing of spatio-temporal trajectory data is important to understand traffic congestion in mass data. However, the data volumes of bus networks in urban cities are growing rapidly, reaching daily volumes of one hundred million datapoints. Accessing and retrieving mass spatio-temporal trajectory data in any field is hard and inefficient due to limited computational capabilities an...
