The aim of this article is two fold. First we discuss the maximum likelihood estimators of the unknown parameters of a two-parameter Birnbaum-Saunders distribution when the data are progressively Type-II censored. The maximum likelihood estimators are obtained using the EM algorithm by exploiting the property that the BirnbaumSaunders distribution can be expressed as an equal mixture of an inve...

Introduction: Fetal intracranial tumors represent only 10% of all antenatal tumors; teratoma being the most common accounting for approximately half of all reported cases followed by astrocytoma, lipoma, choroid plexus papilloma, craniopharyngioma, and primitive neuroectodermal tumor. Usually these tumors clinically manifest in the third trimester of pregnancy, which otherwise nowadays often re...

Tutte and Nash-Williams, independently, gave necessary and sufficient conditions for a connected graph to have at least t edgedisjoint spanning trees. Gusfield introduced the concept of edgetoughness η(G) of a connected graph G, defined as the minimum |S|/(ω(G − S) − 1) taken over all edge-disconnecting sets S of G, where ω(G−S) is the number of connected components of G−S. If a graph has edge-...

We have recently demonstrated that nuclear factor-inducing kinase (NIK) plays a crucial role in osteopontin (OPN)-induced mitogen-activated protein kinase/I kappa B alpha kinase-dependent nuclear factor kappa B (NF kappa B)-mediated promatrix metalloproteinase-9 activation (Rangaswami, H., Bulbule, A., and Kundu, G. C. (2004) J. Biol. Chem. 279, 38921-38935). However, the molecular mechanism(s)...

We propose an interactive content based image retrieval (CBIR) system using M-band wavelet features with Earth Mover’s Distance (EMD). A fuzzy relevance feedback (FRF) method is proposed to enhance the retrieval in order to retrieve more images. So that retrieve images are semantically close to the query. M ×M sub-bands coefficient are used as primitive features, on which, for each pixel, energ...

Mycobacterium leprae has two high-molecular-mass multimodular penicillin-binding proteins (PBPs) of class A, termed PBP1 and PBP1* [Lepage, Dubois, Ghosh, Joris, Mahapatra, Kundu, Basu, Chakrabarti, Cole, Nguyen-Disteche and Ghuysen (1997) J. Bacteriol. 179, 4627-4630]. PBP1-Xaa-beta-lactamase fusions generated periplasmic beta-lactamase activity when Xaa (the amino acid of PBP1 at the fusion j...

Gauge equivalence between the two-dimensional continuous classical Heisenberg ferromagnets(CCHF) of spin 1 2 -the M-I equation with singleside anisotropy and the Zakharov equation(ZE) is established for the easy axis case. The anisotropic CCHF is shown to be gauge equivalent to the isotropic CCHF. Preprint CNLP-1994-05. Alma-Ata.1994 In the study of 1+1 dimensional ferromagnets, a well known La...
