Dissociation constants of thiophencarboxylic acids: calculation of ? constants for the thiophen ring

Journal of the Chemical Society B, Physical Organic, 1970
Dissociation constants for a number of substituted thiophen-5-carboxylic acids have been determined and used to evaluate σ constants for the thiophen molecule. The values obtained are in excellent agreement with those calculated by the method of Dewar and Grisdale and indicate that the sulphur atom has very little effect upon the transmission of ...

Practical Constant-Size Ring Signature

Journal of Computer Science and Technology, 2018
Bitcoin has gained its popularity for almost 10 years as a “secure and anonymous digital currency”. However, according to several recent researches, we know that it can only provide pseudonymity rather than real anonymity, and privacy has been one of the main concerns in the system similar to Bitcoin. Ring signature is a good method for those users who

On constant Armendariz rings

Asian-European Journal of Mathematics, 2016
Let [Formula: see text] be a ring equipped with an endomorphism [Formula: see text] and an [Formula: see text]-derivation [Formula: see text]. In this article, we study [Formula: see text]-constant Armendariz rings and radicals of the Ore extension [Formula: see text], in terms of a [Formula: see text]-constant Armendariz ring [Formula: see text] with

SHUFFLE-RING: A NEW CONSTANT-DEGREE NETWORK

International Journal of Foundations of Computer Science, 1998
The hypercube as a parallel interconnection network has been of academic and engineering concern for tens of year due to its many merits. However, its increasing node degree is an obvious weakness. Some networks such as the cube-connected cycles (CCC) and the de Bruijn network have been proposed to overcome the increasing degree of the hypercube.
