Specific rates of solvolysis at 25 degrees C for isopropyl chloroformate (1) in 24 solvents of widely varying nucleophilicity and ionizing power, plus literature values for studies in water and formic acid, are reported. Previously published solvolytic rate constants at 40.0 degrees C are supplemented with two additional values in the highly ionizing fluoroalcohols. These rates are now are anal...

Grothendieck attache à une variété abélienne sur un corps de nombres des groupes monodromie finie en chaque place mauvaise réduction. On montre l'existence variétés abéliennes avec p-partie maximale pour p impair ainsi qu'une nouvelle borne la 2-partie ces dans le cas d'une multiplication complexe (CM). que cette est atteinte. La construction se fait par torsion CM ce qui intervenir résolution ...

Fig. 1. (A) Peripheral blood shows neutrophils with toxic granules and two intra-cytoplasmic yeast forms of Histoplasma capsulatum in the cell on the left (May-Grunwald Giemsa, ×1,000). Inset: The fungus was brightly positive for periodic acid–Schiff stain (hematoxylin counterstain, ×1,000). (B) Hemodilute bone marrow smears showed dysgranulopoiesis with 5% blasts (May-Grunwald Giemsa, ×1,000)....

This paper presents a series of new results in modeling of the Grünwald-Letnikov discretetime fractional difference by means of discrete-time Laguerre filers. The introduced Laguerrebased difference LD and combined fractional/Laguerre-based difference CFLD are shown to perfectly approximate its fractional difference original, for fractional order α ∈ 0, 2 . This paper is culminated with the pre...

This paper deals with synchronization between a fractional order Coullet chaotic system and an integer order Rabinovich-Fabrikant chaotic system by using tracking control and stability theory of fractional order system. An effective controller is designed to synchronize these two systems. Numerical simulations have been done by using Mathematica and Matlab both. Numerical solutions via Grünwald...

The specific rates of solvolysis (including those obtained from the literature) of isopropenyl chloroformate (1) are analyzed using the extended Grunwald-Winstein equation, involving the N(T) scale of solvent nucleophilicity (S-methyldibenzothiophenium ion) combined with a Y(Cl) scale based on 1-adamantyl chloride solvolysis. A similarity model approach, using phenyl chloroformate solvolyses fo...

In this paper we present a random walk model for approximating a Lévy-Feller advection-dispersion process, governed by the Lévy-Feller advection-dispersion differential equation (LFADE). We show that the random walk model converges to LFADE by use of a properly scaled transition to vanishing space and time steps. We propose an explicit finite difference approximation (EFDA) for LFADE, resulting...

In our earlier paper, there are special cases in which the main theorem could not hold for reasons related to Grunwald–Wang theorem. We correct statement and its proof, we include a short discussion of added hypothesis “viability” needed make true.
