During the routine survey for exploring hidden macrofungal wealth of tropical Sal ( Shorea robusta Roth) forests in West Bengal and Jharkhand (India), we found a specimen similar to Tylopilus plumbeoviolaceous (Snell & E.A.Dick) Snell E.A.Dick. After careful morphological observations phylogenetic analysis, species was be conspecific with glutinosus Iqbal Hosen, recently established taxon f...

We present a new iterative procedure for solving the multiple stopping problem in discrete time and discuss the stability of the algorithm. The algorithm produces monotonically increasing approximations of the Snell envelope, which coincide with the Snell envelope after finitely many steps. Contrary to backward dynamic programming, the algorithm allows to calculate approximative solutions with ...

This raises the possibility that the processing mechanisms may differ in different tissues. Since bovine /.-endorphin appears to have the same primary structure as rat /.-endorphin (Rubinstein et al., 1977; Li et al., 1977), it is anticipated that the four peptides isolated from ox pituitary, described here, will prove valuable as ‘marker’ peptides in studies on the distribution of /.-endorphin...

The main objective of this paper is to estimate the survival of HIV/AIDS patients who are undergoing Antiretroviral Therapy in an ART centre, Delh i. Non Parametric Maximum Likelihood Estimation NPMLE (E-M) for interval censoring and KM survival plot for left, right and mid-point imputation have been used to estimate the survival of these patients. It has been observed that the mid-point impute...

We present an iterative procedure for computing the optimal Bermudan stopping time, hence the Bermudan Snell envelope. The method produces an increasing sequence of approximations of the Snell envelope from below, which coincide with the Snell envelope after finitely many steps. Then, by duality, the method induces a convergent sequence of upper bounds as well. In a Markovian setting the presen...
