It has been reported that the Src family kinases-mediated tyrosine phosphorylation of alpha(1C) subunits of L-type voltage-gated calcium channels (L-VGCCs) potentiates the channel currents. In this study, we evaluated the alterations in the tyrosine phosphorylation level of alpha(1C) and in the interactions involving Src/Fyn, alpha(1C) and PSD-95 in the(More)
Bovine brain contains two calmodulin-dependent phosphodiesterase kinases which are separated on Sephacryl S-300 column. One of these kinases has been purified to homogeneity and shown to belong to the calmodulin-dependent protein kinase II family. Phosphorylation of the 63 kDa phosphodiesterase by this purified protein kinase results in the incorporation of(More)
Social relationships such as friendship and partner choice are ruled by the proximity principle, which states that themore similar two individuals are, themore likely theywill become friends. However, proximity, similarity, and friendship are concepts with blurred edges and imprecise grades of membership. This study shows how to simulate these friendship(More)

In this paper we regard legged locomotion (e.g., running) as adaptive vibration, which is capable of adapting to changes in internal parameters and in the external environment. We propose control concepts for such adaptive running in general, and present a theoretical study of the bounding locomotion of a quadruped robot according to the proposed control(More)
The proposed ARCH and its extension model have brought a powerful tool for the study of stock market volatility as well as verify that a “high risk brings high-yield” and the “leverage effect” of stock market. This paper gives modeling analysis by using the ARCH group models; in the last ten years Shanghai’s index returns, concluded that there are(More)
OBJECTIVES The white blood cell (WBC) count is a simple and convenient marker of inflammation for use in medical practice; however, its association with non-alcoholic fatty liver disease (NAFLD) has not been determined. We examined the relationship between WBC and NAFLD to provide a convenient and useful marker for the prediction of NAFLD. SETTING A(More)
This paper examines a passivity analysis for a class of discrete-time recurrent neural networks DRNNs with norm-bounded time-varying parameter uncertainties and interval time-varying delay. The activation functions are assumed to be globally Lipschitz continuous. Based on an appropriate type of Lyapunov functional, sufficient passivity conditions for the(More)
The problem of passivity analysis for a class of discrete-time stochastic neural networks DSNNs with time-varying interval delay is investigated. The delay-dependent sufficient criteria are derived in terms of linear matrix inequalities LMIs . The results are shown to be generalization of some previous results and are less conservative than the existing(More)
