Models of working memory (WM) suggest that the contents of WM are separated from perceptual input by a gate, that enables shielding information against interference when closed, and allows for rapid updating when open. Recent work in the declarative WM domain provided evidence for this notion, demonstrating the behavioral cost of opening and closing the gate. The goal of the present work was to...

In the present paper the authors have introduced a new updated two-way generalized vernam cipher method called TTSJA. Chatterjee et. al developed a method [1] where they used three independent methods such as MSA [2], NJJSAA [3] and modified generalized vernam cipher method. Nath et al already developed some symmetric key methods [2,3,4,5] where they have used bit manipulation method and some r...

The distribution of Fermat quotients and related sequences is interesting from several perspectives. First, there are several applications, in particular to algebraic number theory and computer science. Fermat quotients play for instance a role in primality testing (see [L]) and are well-studied as model for generating pseudo-random numbers. (See [COW].) From the analytical side, establishing d...

Abstract. We estimate multiplicative character sums taken on the values of a nonhomogeneous Beatty sequence {⌊αn+ β⌋ : n = 1, 2, . . . }, where α, β ∈ R, and α is irrational. In particular, our bounds imply that for fixed α, β and a small real number ε > 0, if p is sufficiently large and p1/3+ε ≤ N ≤ p1/2+ε, then among the first N elements of the Beatty sequence there are N/2+ o(N) quadratic no...
