The method of time domain electromagnetic (TDEM) migration is used for fast imaging of subsurface geoelectrical structures. The computation of the migration field is based on downward extrapolation of the observed field in reverse time. In this paper we examine an effective method of EM migration based on the operator of an integral transformation in the spatial-temporal domain. The migration c...

A total of 83 faecal samples carrying rotavirus were used in this survey. Five different electrophoretypes were distinguished according to their migration patterns. All the rotaviruses examined in this research proved to be group A and to have short migration patterns. While local migration patterns were detected in individual herds (e.g. A, B, C, M, P and T), two different migration profiles w...

Light is able to remotely move matter. Among various driving forces, laser-induced metal sphere migration in glass has been reported. The temperature on the laser-illuminated side of the sphere was higher than that on the non-illuminated side. This temperature gradient caused non-uniformity in the interfacial tension between the glass and the melted metal as the tension decreased with increasin...

Potassium channels have been involved in epithelial tumorigenesis but the role of small-conductance Ca(2+)-activated K(+) channels is unknown. We report here that small-conductance Ca(2+)-activated K(+) channels are expressed in a highly metastasizing mammary cancer cell line, MDA-MB-435s. Patch-clamp recordings showed typical small-conductance Ca(2+)-activated K(+) channel-mediated currents se...

TCPSO (Two-swarm Cooperative Particle Swarm Optimization) has been proposed by Sun and Li in 2014. TCPSO divides the swarms into two groups with different migration rules, and it has higher performance for high-dimensional nonlinear optimization problems than traditional PSO and other modified method of PSO. This paper proposes a particle swarm optimization by modifying TCPSO to avoid inappropr...

PURPOSE The stromal-derived factor (SDF)-1alpha and the CXC receptor (CXCR)-4 jointly regulate the trafficking of various cell types and play a pivotal role in cell migration, proliferation, and survival. The purpose of this study was to assess whether curcumin inhibits human retinal endothelial cell (HREC) migration by interfering with SDF-1alpha/CXCR4 signaling. METHODS Primary HREC culture...

Classical equilibrium molecular dynamics simulations have been performed to investigate dynamical properties of cage radial breathing modes and intra- and inter-cage hydrogen migration in both pure hydrogen and mixed hydrogen-tetrahydrofuran sII hydrates at 0.05 kbar and up to 250 K. For the mixed H(2)-THF system in which there is single H(2) occupation of the small cage (labelled "1SC 1LC"), w...
