Accounting for the Role of Long Walks on Networks via a New Matrix Function [PDF]
, 2016 We introduce a new matrix function for studying graphs and real-world networks based on a double-factorial penalization of walks between nodes in a graph. This new matrix function is based on the matrix error function.

A Compact Formula for Rotations as Spin Matrix Polynomials [PDF]
, 2014 Group elements of SU(2) are expressed in closed form as finite polynomials of the Lie algebra generators, for all definite spin representations of the rotation group.

Extended central factorial polynomials of the second kind
Advances in Difference Equations, 2019 In this paper, we consider the extended central factorial polynomials and numbers of the second kind, and investigate some properties and identities for these polynomials and numbers.

Two variable higher-order central Fubini polynomials
Journal of Inequalities and Applications, 2019 Recently, the central Fubini polynomials were introduced in connection with central factorial numbers of the second kind. In this paper, we consider two variable higher-order central Fubini polynomials as a ‘central analogue’ of two variable higher-order

Generic and rhetorical structures of texts : two sides of the same coin? [PDF]
, 2005 Two major approaches to textual macro-structures have been developed during the last decades: Register & Genre Theory (R>) and Rhetorical Structure Theory (RST).

Quantum limits on phase-preserving linear amplifiers [PDF]
, 2012 The purpose of a phase-preserving linear amplifier is to make a small signal larger, regardless of its phase, so that it can be perceived by instruments incapable of resolving the original signal, while sacrificing as little as possible in signal-to ...

Small and large scale behavior of moments of poisson cluster processes [PDF]
, 2017 Poisson cluster processes are special point processes that find use in modeling Internet traffic, neural spike trains, computer failure times and other real-life phenomena. The focus of this work is on the various moments and cumulants of Poisson cluster

On photon statistics parametrized by a non-central Wishart random matrix
, 2015 In order to tackle parameter estimation of photocounting distributions, polykays of acting intensities are proposed as a new tool for computing photon statistics.

q-Differential equations for q-classical polynomials and q-Jacobi-Stirling numbers [PDF]
, 2015 We introduce, characterise and provide a combinatorial interpretation for the so-called q-Jacobi–Stirling numbers. This study is motivated by their key role in the (reciprocal) expansion of any power of a second order q-differential operator having the
