(Received) Exact diagonalizations of two dimensional small t–J clusters reveal dominant hole-hole correlations at distance √ 2 (ie between holes on next nearest neighbor sites). A new form of singlet d x 2 −y 2 pair operator is proposed to account for the spatial extention of the two hole-bound pair beyond nearest neighbor sites.

The results contained in this paper are the result of a study regarding fractional calculus combined with classical theory differential subordination established for analytic complex valued functions. A new operator is introduced by applying Libera integral and order λ Many properties obtained newly defined using famous lemmas proved important scientists concerned geometric function theory, suc...

In this paper, we consider some relations related to the representations of starlike and convex functions, obtain sufficient conditions for functions by using theory differential subordination. Actually, generalize a result Suffridge analytic with missing coefficients then apply that generalization obtaining different methods implications or functions. Our results improve previous in literature.

We consider the maximum entropy extention of a partially specified autocovariance sequence of a periodically correlated process. The sequence may be specified on a non-contiguous set. We give a method which solves the problem completely—it gives the positive definite solution when it exists and reports that it does not exist otherwise. The method is numerically reliable even when the solution i...

In this paper we propose an architecture as a framework for decomposition and analysis of hybrid systems. We represent a computer system's behaviour in interaction with its physical environment using modular models and the combination of discrete and continuous modelling techniques. To this end, a modular extention of timed transition systems, Hybrid Transition Systems, are presented. For this ...

This article presents a case of infective endocarditis secondary to ventricular septal defect with an extention of a process to mitral and aortic valves.
