in this paper, we consider an arbitrary binary polynomial sequence {a_n} and then give a lower triangular matrix representation of this sequence. as main result, we obtain a factorization of the innite generalized pascal matrix in terms of this new matrix, using a riordan group approach. further some interesting results and applications are derived.

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.

Boson pair production is one of the few processes that have significant effects from triple boson vertices at tree level. These couplings are predicted in the standard model and are directly related to its gauge group structure. One of the goals of diboson measurements is to limit deviations from the standard model values of these triple gauge couplings (TGCs). Such deviations could be observed...

We present time resolved J-band (1.025 – 1.340 μm) infrared spectra of the short-period dwarf novae (DNe) WZ Sge, VY Aqr and single spectra of the short-period DNe EF Peg and the novalike variable PX And. There is some evidence in the spectra of VY Aqr and EF Peg that we have detected the secondary star, both in the continuum slope and also through the possible presence of spectral features. Th...

ten varieties of iranian soybeans are cultivated in different areas of the country; persia or sahar (sr), hill (hl), williams (wz), gorgan 3 (gn), clarke (kl), hawkey (hk), zaan (zn), harcor (hr), dare (dr) and simes (ss), grown in tropical regions. samples of these 10 varieties were obtained from the institute of plant and seed research. after sample preparation, their oils were extracted and ...

We use WZ-summation methods to compute recurrences for the Ising-class integrals Cn,k. In this context, we describe an algorithmic approach to obtain homogeneous and inhomogeneous recurrences for a general class of multiple contour integrals of Barnes’ type.

The microstructure, texture, and mechanical properties of the asymmetric welded joint in variable polarity plasma arc (VPPA) welding were studied discussed this paper. was obtained through horizontal welding, where effect gravity caused material flow. results showed that grain size low angle boundary (LAGB) at both sides asymmetric; differed by a factor 1.3. average Base Metal (BM), Lower-weld ...
