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...

The 4-year drawdown of Horsetooth Reservoir, Colorado, for dam maintenance, provides a case study analog of vegetation response on sediment that might be exposed from removal of a tall dam. Early vegetation recovery on the exposed reservoir bottom was a combination of (1) vegetation colonization on bare, moist substrates typical of riparian zones and reservoir sediment of shallow dams and (2) a...

To correct this deficiency of nature, water reservoirs are built at existing sources and resources managed (corrected). In order to fully effectively use the rivers streams prevent floods, it is necessary river flow. This problem can be solved by building artificial bodies - reservoirs. Each unique in terms its source saturation hydrological regime. At same time, depending on type management re...

In several mammalian species, circadian pacemakers of breeding females synchronize the developing clocks of offspring by as of yet unspecified mechanisms. The present study assessed whether maternal communication of circadian rhythms extends beyond setting pacemaker phase to include transfer of a fundamental reorganization of component circadian oscillators from dams to pups. In Experiment 1, a...

Abstract Displacement monitoring method of reservoir dam is a key research topic at present. In order to better display the overall efficiency horizontal displacement and vertical monitoring, numerical simulation analysis ecological small based on maximum entropy algorithm proposed. The virtual value calculated by algorithm, probability distribution function random variables obtained. comprehen...

Evaluation of the sliding stability concrete dams requires use numerical tools not only able to simulate coupled hydromechanical behavior but also adequately represent foundation discontinuities and specific features dam foundations. The formulation a three-dimensional (3D) small displacement finite element model based on interface elements is presented. In this model, hydraulic simulated assum...

For optimization of real-world arch dams, it is unavoidable to consider two or more conflicting objectives. This paper employs two multi-objective differential evolution algorithms (MoDE) in combination of a parallel working MATLAB-APDL code to obtain a set of Pareto solutions for optimal shape of arch dams. Full dam-reservoir interaction subjected to seismic loading is considered. A benchmark ...
