Let F be a continuous function from an open subset D of a separable Banach space X into a Banach space Y. We show that if there is a dense G8 subset A of D and a Gs subset H of X whose closure has nonempty interior, such that for each a E A and each x E H the directional derivative DxF(a) of F at a in the direction x exists, then F is Giteaux differentiable on a dense G8 subset of D. If X is re...
Five plasmids, distinguishable by their molecular weights (10(6), 2 x 10(6), 5 x 10(6), 10(7), 3 x 10(7), respectively) were isolated from Streptococcus lactis C2. A spontaneous proteinase-negative derivative of this strain lacked the 10(7) plasmid.
Using the chain rule, we give a homotopy theoretic approach to identifying the derivative of the functor X 7→ Q+(X).
Background: The aim of this study was to evaluate the radioprotective capacity of some novel aminoalkylated dithiocarbamic acid potassium salts against γ-irradiation in mice. Materials and Methods: Eight compounds containing 2-aminoethyl-, 3- aminopropyl-, 4-aminobutyl-, 5-aminopentyl-, 6- aminohexyl-, 7-aminoheptyl-, 8-aminooctyl and 9- aminononyl of dithiocarbamate derivatives were prepared. ...
The reaction of phenylhydrazoethyl acetoacetate (1) with cyanoacetyl hydrazine (2) in an oil bath in the presence of ammonium acetate gave the pyridazine derivative 4. However, carrying the same reaction but in ethanolic/Et3N gave the pyrazole derivative 5. Compounds 4 and 5 were used in a series of heterocyclization reactions to afford products that showed anti-tumor activities towards three c...
of course then depends not only on the point z but also on the direction of approach 8, that is, on the slope m = y' = dy/dx. The main theorem is that, plotted in the a, ß plane, the locus of points 7, corresponding to a given point z, is a circle (the derivative circlet), or more accurately a suitably parametrized circle, which I have termed a clock (the derivative clock). Various expressions ...
where u = u(t, x) : R → C is a complex-valued wave function, both λ 6= 0 and k > 5 are real numbers. A great deal of interesting research has been devoted to the mathematical analysis for the derivative nonlinear Schrödinger equations [3, 4, 6, 7, 8, 9, 10, 11, 13, 18, 21]. In [13], C. E. Kenig, G. Ponce and L. Vega studied the local existence theory for the Cauchy problem of the derivative non...
