We describe various aspects of the Al-Salam-Carlitz q-Charlier polynomials. These include combinatorial descriptions of the moments, the orthogonality relation, and the linearization coefficients.

We discuss the embedding of R-Parity preserving Minimal Left Right Supersym-metric models into Pati-Salam and SO(10) GUTs.

Using standard WHO methodology, this study investigated the susceptibility of 4th instar Aedes aegypti (L) and Culex annulirostris (Skuse) larvae to three extracts from Callitris glaucophylla (J. Thompson & L. Johnson) (1: steam distillation extract, 2: liquefied refrigerant gas extract, and 3: methanol reflux extract), lambda-cyhalothrin (a synthetic pyrethroid insecticide) and fenitrothion (a...

AbstractBackground: COVID-19 pandemic considered a worldwide and social emergency that requires the application of strict measures to prevent fast spread disease. Health Care Workers (HCWs) compliance control is affected determined by their Knowledge, Attitudes, Practices (KAP) towards virus Aim work: To evaluate knowledge, attitude practice among HCWs COVID 19 Methods: A cross-sectional study ...

Maximally extending the Higgs sector of the Glashow-Salam-Weinberg model by including all scalar and pseudoscalar J = 0 states expected for 2 generations of quarks, I demonstrate that the Cabibbo angle is given by tan 2 θ c =

A model of a q-harmonic oscillator based on q-Charlier poly-nomials of Al-Salam and Carlitz is discussed. Simple explicit realization of q-creation and q-annihilation operators, q-coherent states and an ana-log of the Fourier transformation are found. A connection of the kernel of this transform with biorthogonal rational functions is observed. Models of q-harmonic oscillators are being develop...

We describe various aspects of the Al-Salam-Chihara q-Charlier polynomials. These include combinatorial descriptions of the polynomials, the moments, the orthogonality relation and a combinatorial proof of Anshelevich’s recent result on the linearization coefficients.
