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.

We present results from detailed computations focused on chemical mixing in convective regions of very low mass stars (VLMs) and brown dwarfs (BDs) during deuterium burning. Computations are made both in the instantaneous and in the coupled–diffusive mixing schemes to check which mixing is required to treat these phases. The convective timescale is much shorter than the nuclear time scales for ...

In this work we propose a lightweight scheme for negotiating client’s capabilities in the context of end-end content adaptation for wireless web access. Our method is much less complex then W3C’s proposed CC/PP framework. We suggest that for the purposes of content negotiation all (mobile) clients could be grouped into a few relatively large categories. With this assumption we simplify the CC/P...

The interaction of galaxies not only occurs in galactic scales, but also may be linked to the binary cores in active galactic galaxies. The presence of a binary in the center of galaxies was suggested by Begelman, Blandford and Rees (1980). Gaskell (1983) suggests that supermassive binaries may account for the observed structure of emission line profiles such as double peaks displaced by a sign...

almcm-41 was applied for adsorption of methylene blue (mb) and auramine (au) in single and binary component systems. in the single component systems, almcm-41 represents higher adsorption capacity for mb than au with the maximal adsorption capacity of 2.07×10−4 and 1.15×10−4 mol/g at 25 ˚c for mb and au, respectively. in the binary component system, mb and au exhibit competitive adsorption onto...

Relativistic emission lines generated by thin accretion disks around rotating black holes are an important diagnostic tool for testing gravity near the horizon. The iron K–line is of special importance for the interpretation of the X–ray emission of Seyfert galaxies, quasars and galactic X–ray binary systems. A generalized kinematic model is presented which includes radial drifts and non–Kepler...
