We study the crystal base of the negative part of a quantum group. An explicit realization of the crystal is given in terms of Young tableaux for types An, Bn, Cn, Dn, and G2. Connection between our realization and a previous realization of Cliff is also given.

We present an INTEGRAL data analysis of the X-ray transient SAX J2103.5+4545 during two outbursts detected in December 2002. The INTEGRAL coordinates and error circle agree with the position of the recently proposed optical counterpart. A power-law plus cutoff model provided a good fit to the 4–150 keV spectrum yielding a photon index of 1.0±0.1, a cutoff energy E cut = 7.6 ± 2.0 keV and a fold...

in this paper‎, ‎we determine the simple groups $g=ab$‎, ‎where $b$ is isomorphic to $l_{3}(4)$ and $a$ isomorphic to an alternating or a symmetric group on $ngeq5$‎, ‎letters‎.

Let $G$ be a finite group. The graph $D(G)$ is a divisibility graph of $G$. Its vertex set is the non-central conjugacy class sizes of $G$ and there is an edge between vertices $a$ and $b$ if and only if $a|b$ or $b|a$. In this paper, we investigate the structure of the divisibility graph $D(G)$ for a non-solvable group with $sigma^{ast}(G)=2$, a finite simple group $G$ that satisfies the one-p...

We utilize isotherm models in contributing to scholarly knowledge in simple terms, to measure the forces or energy defining certain adsorption phenomenon. Gas Chromatography coupled with Mass Spectrophotometer detector (GCMS) was utilized to measure equilibrium phase atrazine after adsorption onto Shea nut Shells (SS) acid derived activated carbon. Data were fitted into the D-R and Temkin i...

serum opsonic capacity against b. pertussis was studied by using quantitative chemiluminescence (cl), a method known to have several advantages over conventional methods in evaluating opsonization and phagocytosis. sera from unvaccinated infants was shown not to contain opsonins against b. pertussis and in unvaccinated infants suffering from whooping cough, no opsonins were detected. in adults ...

consider the following consistent sylvester tensor equation[mathscr{x}times_1 a +mathscr{x}times_2 b+mathscr{x}times_3 c=mathscr{d},]where the matrices $a,b, c$ and the tensor $mathscr{d}$ are given and $mathscr{x}$ is the unknown tensor. the current paper concerns with examining a simple and neat framework for accelerating the speed of convergence of the gradient-based iterative algorithm and ...

a practical and green method for the synthesis of 5h-dibenzo[b,i]xanthene-tetraones and spiro[dibenzo[b,i]xanthene-13,3'-indoline]-pentaones by the condensation of 2-hydroxynaphthalene-1,4-dione with aldehydes or isatins, respectively, in the presence of a catalytic amount of cellulose sulfuric acid (csa) under solvent-free conditions at 100 °c is described. the significant features of this pro...

Case Report: Some viruses have been reported to cause respiratory and gastroenteric infections simultaneously. In this case we present isolation of human respiratory virus (RSV) type B from diarrheal sample of a 12 months' child with acute gastroenteritis. Results: The results indicated the presence of RSV subtype B genome in all three stool samples. Moreover, no sign of co-infections with oth...
