Introduction: Human embryonic stem cells (hESCs) are pluripotent cells that can proliferate and differentiate to many cell types. Their electrophysiological properties have not yet been chracterzed. In this study, the passive properties (such as resting membrane potential, input resistance and capacitance) and the contribution of delayed rectifier K+ channel currents to the membrane conducta...

Pipe routing and clamp layout for aeroengine are NP-hard computational problems complex engineering design processes. Besides space constraints rules, there assembly between pipes clamps, which usually lead to repeatedly modifications pipe designs. In order solve the of coupling them, an integrated optimization method is proposed. To this end, MOALO (multiobjective ant lion optimizer) algorithm...

Tarsorrhaphy is finding increasing indications because of the resultant improvement in comeal metabolic activity and also the protective cover given to the cornea. Different techniques' have been described for performing the tarsorrhaphy, but the basic principle remains the same. It is to produce adhesions between the 2 lid margins by creating a raw intermarginal strip on the 2 lids. Tarsorrhap...

Clamp loaders load ring-shaped sliding clamps onto DNA where the clamps serve as processivity factors for DNA polymerases. In the first stage of clamp loading, clamp loaders bind and stabilize clamps in an open conformation, and in the second stage, clamp loaders place the open clamps around DNA so that the clamps encircle DNA. Here, the mechanism of the initial clamp opening stage is investiga...

Abstract The X-ray inspection of wire clamps is used more and widely. detection uses UAV (Unmanned Aerial Vehicle) to inspect the clamp with high voltage, which directly contacts electrified clamp. When strength overhead transmission line exceeds air breakdown strength, extreme discharges will occur, so control data performance influenced, even cause a crash. electromagnetic interference can al...
