The data from the various neutrino experiments indicate a bimaximal mixing among three neutrino generations. The atmospheric neutrino puzzle requires a near maximal mixing between a pair of neutrinos [1]. The solar neutrino puzzle has various possible solutions but the large angle MSW solution is favoured [2]. As the mass squared difference required for these two solutions differ by about few o...

this paper represents a new region-based active contour model that can be used to segment images with intensity non-uniformity and high level noise. the main idea of our proposed method is to use gaussian distributions with different means and variances with incorporation of intensity non-uniformity model for image segmentation. in order to integrate the spatial information between neighboring ...

We investigate the SO(10) grand unified model with generation flipping. The model contains one extra matter multiplet ψ(10) and it mixes with the usual matter multiplets ψi(16) when the SO(10) is broken down to SU(5). We find the parameter region of the model in which the observed quark masses and mixings are well reproduced. The resulting parameter region is consistent with the observation tha...

In the Standard Model (and MSSM), renormalization effects on neutrino mixing are generally very small and the attractive fixed points are at vanishing neutrino mixing. However for multi-higgs extensions of the Standard Model, renormalization effects on neutrino mixing can be large and nontrivial fixed points are possible. Here we examine a simple two-higgs model. For two flavors, maximal mixing...

In this paper, we introduce a formal model which describes consistently levels of detail and regions of interest for the embedded coding and progressive transmission of raster images. This model serves as the foundation of an image communication system which supports the progressive, redundancy-free transmission of multiple, possibly overlapping regions of interest in an image. We propose the r...

Bacterial cellulose (BC) has a basic cellulose structure that gives high purity, high crystalline ability, high mechanical strength, and high water holding capacity. During the last few decades, BC has gained as an important biomaterial because of these unique physical and chemical characteristics. BC is synthesized by Acetobacter xylinum extracellularly in a suitable substrate media. Researche...

The nonideal mixing of phosphatidylserine (PS) and phosphatidylcholine (PC) binary lipid mixtures was studied by computer simulation based on a model wherein the excess energy of mixing is divided between an electrostatic term and one adjustable term delta Em that includes all other nonideal interactions. The lateral distribution of the lipids and the energy of the mixtures were obtained by usi...

Very recently the atomic masses of neutron-rich Zr isotopes, from Zr to Zr, have been measured with high precision. Using a schematic Interacting Boson Model (IBM) Hamiltonian, the evolution from spherical to deformed shapes along the chain of Zr isotopes, describing at the same time the excitation energies as well as the two-neutron separation energies, can be rather well reproduced. The inter...
