Ca 2+ release from the sarcoplasmic reticulum (SR) via the ryanodine receptor (RyR) regulates both general cellular activities such as metabolism and more specific events such as smooth muscle contraction. RyR opening is itself promoted by Ca 2+ (Endo et al., 1970; Fabiato, 1983) and decreased by FK506 binding proteins (FKBPs) (Brillantes et al., 1994; Xin et al., 2002). Among other substances,...

This paper compares two influential attempts at presenting a comprehensive framework of knowledge management. For each perspective the author examines theoretical foundations, highlights conceptual elements and themes, and discusses the role of information and information management. Ikujiro Nonaka and Hirotaka Takeuchi analyze the dynamics of knowledge creation, particularly the importance of ...

With the development of space science and technology, some countries have launched unmanned planetary exploration programs. Because planet surfaces are rough and formidable, planetary exploration rovers were used as a versatile and safe alternative to manned space missions to explore the planets. In recent years, many types of planetary rovers were developed including tracked type, legged type,...

In this paper, we present an approximate method to solve the solution of the second kind Volterra integral equations. This method is based on a previous scheme, applied by Maleknejad ‎et al., ‎‎[K. Maleknejad ‎and Aghazadeh, Numerical solution of Volterra integral equations of the second kind with convolution kernel by using Taylor-series expansion method, ‎Appl. Math. Comput.‎ (2005)]‎ to gain...

Finite Quot schemes were used by Bertram, Johnson, and the first author to study Le Potier's strange duality conjecture on del Pezzo surfaces when one of moduli spaces is Hilbert scheme points. In order rigorously enumerate finite scheme, we space limit stable pairs in which target has rank a smooth complex projective surface. We obtain an embedding this into that induces perfect obstruction th...
