The gap junction channel is formed by proper docking of two hemichannels. Depending on the connexin(s) in the hemichannels, homotypic and heterotypic gap junction channels can be formed. Previous studies suggest that the extracellular loop 2 (E2) is an important molecular domain for heterotypic compatibility. Based on the crystal structure of the Cx26 gap(More)
Ligand-bridged mixed-valence ions can exist in either valence-localized (double-minimum ground potential energy surface) or valence-delocalized (single-minimum ground PE surface) form.' The determining factor is the balance between twice the initial-state/final-state electronic coupling energy (&) and the sum of the zeroth-order reorganization or trapping(More)
Recently we have begun to explore the role of temperature in optical intervalence charge-transfer (IVCT) processes.' For symmetrical mixed-valencecomplexes, we find that the energetics of IVCT are essentially unaffected by changes in temperature.' For asymmetric complexes, on the other hand, substantial energetic effects can exist, at least for valence(More)
To further improve the performance of wavelet neural network blind equalization based on constant modulus algorithm (CMA) cost function, an instantaneous gradient based dual mode between modified constant modulus algorithm (MCMA) and decision directed (DD) algorithm was proposed. The wavelet neural network weights change quantity of the adjacent iterative(More)
A variable step-size control by error power was proposed to improve the performance of adaptive constant modulus blind equalization algorithm based on the analysis of the cost function. In the Constant Modulus Algorithm (CMA), large step-size can achieve faster convergence rate, but the steady-state residual error is big, on the contrary, small step-size(More)
OBJECTIVE To observe the effects of auricular acupuncture on the learning and memory abilities of model rats with Alzheimer's disease (AD), and investigate its mechanism. METHODS Thirty SD rats were randomly divided into a control group, a model group and an auricular acupuncture group, 10 rats in each group. The model rats with AD were established by(More)
