The aim of the present study was to prepare, characterize and in-vitro evaluation of a Winsor-IV type microemulsion based drug delivery system incorporating celecoxib as BCS class–II model drug. Attempts were made to prepare cost effective O/W microemulsion using Tween 80, Glycerol, sunflower oil and water. The existence of microemulsion zone was investigated using phase diagrams. The systems w...

Using the near infrared uxes of local galaxies derived from Cosmic Background Explorer (COBE)/Diiuse Infrared Background Experiment (DIRBE) 1 J(1.25 m) K (2.2 m) & L (3.5 m) band maps and published Cepheid distances, we construct Tully-Fisher diagrams for the nearby galaxies. The measured dispersions in these luminosity-linewidth diagrams are remarkably small: J = 0:09 magnitudes, K = 0:13 magn...

Recent research on timing verification of digital interface circuits has implicitly assumed that the delays of different signal transitions in the circuit are independent of one another. However timing diagrams in data sheets clearly specify correlation information. If timing correlation is ignored the results of verification can be overly pessimistic. In this paper we propose a probabilistic t...

The construction of modern cryptographic systems relies on the so-called resilient Boolean functions, a special class of Boolean functions that possesses a balance between a high level of nonlinearity and correlation immunity. In this paper, we discuss the problem of the compact representation and efficient construction of resilient functions. Binary Decision Diagrams (BDDs) were extensively us...

Inelastic Neutron Scattering (INS) data in La2-xSrxCuO4 (LSCO), YBa2Cu3O6+x (YBCO) and Bi2Sr2CaCu2O8+x (Bi2212) are discussed. In the literature, the INS spectra remain far from being comprehensively understood. We show that local (Q-integrated) susceptibility data and the energy dependence of the spin susceptibility at antiferromagnetic vector, QAF = (π,π), can be interpreted by using the phas...

The one-dimensional partially asymmetric simple exclusion process with open boundaries is considered. The stationary state, which is known to be constructed in a matrix product form, is studied by applying the theory of q-orthogonal polynomials. Using a formula of the q-Hermite polynomials, the average density profile is computed in the thermodynamic limit. The phase diagram for the correlation...

Interacting bosons generically form a superfluid state. In the presence of disorder it can get converted into a compressible Bose glass state. Here we study such a transition in one dimension at moderate interaction using bosonization and renormalization group techniques. We derive the two-loop scaling equations and discuss the phase diagram. We find that the correlation functions at the transi...

We apply the dinamically driven renormalization group to study the critical properties of the Domany-Kinzel probabilistic cellular automaton. To preserve the absorbing state clusters with at least one site occupied are renormalized into a one occupied site and clusters with all sites empty are renormalized into a one empty site. We have obtained the phase diagram as well as the critical exponen...

Consider the standard Poisson process in the first quadrant of the Euclidean plane, and for any point (u, v) of this quadrant take the Young diagram obtained by applying the Robinson–Schensted correspondence to the intersection of the Poisson point configuration with the rectangle with vertices (0, 0), (u, 0), (u, v), (0, v). It is known that the distribution of the random Young diagram thus ob...

A technique for computing the switching activity of synchronous Finite State Machine (FSM) implementations including the influence of temporal correlation among the next state signals is described. The approach is based upon the computation that a FSM is in a given state which, in turn, is used to compute the conditional probability that a next state bit changes given its present state value. A...
