What is the derivative formula? The derivative of a function y = f(x) can be expressed as dy/dx = d/dx f(x), where dy/dx is called derivative of y with respect to x and d/dx f(x) is the derivative of f(x) with respect to x. ...

Rocaglate, a class of structurally complex secondary metabolites from plants of the Aglaia genus (Meliaceae), have attracted great attentions for their considerable cytotoxicity1–5. Rocaglates could block cell cycle progression6–13 from G2 to M and exhibited promising activity in human tumor cell...
The molecular formula of compound 1 was determined to be C20H18N2O3 on the basis of high-resolution fast atom bombardment MS (HRFABMS) (m/z 335.1393 [M þ H] þ , calcd. for 335.1396). The 1H and 13C NMR data of 1 were very similar to those of nocazine A,24 a metabolite ...
The proofs of these formulas, which have applications in signal detection and estimation problems, call heavily upon recent results in martingale theory, especially a general formula of Doleans-Dade for the logarithm of a strictly positive martingale in terms of a function measuring its jumps.关键...
