Appell polynomials and their relatives II. Boolean theory

open access: yes, 2007
The Appell-type polynomial family corresponding to the simplest non-commutative derivative operator turns out to be connected with the Boolean probability theory, the simplest of the three universal non-commutative probability theories (the other two ...

Self‐pruning in tree crowns is influenced by functional strategies and neighbourhood interactions

open access: yesFunctional Ecology, Volume 39, Issue 9, Page 2234-2250, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract As canopy closure imposes light limitation in forests, the dieback of trees' lower branches, known as self‐pruning, defines their live crown base and shapes the structure and function of entire stands.

A New Generalization of mth-Order Laguerre-Based Appell Polynomials Associated with Two-Variable General Polynomials

open access: yesMathematics
This paper presents a novel generalization of the mth-order Laguerre and Laguerre-based Appell polynomials and examines their fundamental properties. By establishing quasi-monomiality, we derive key results, including recurrence relations, multiplicative

Bilateral series in terms of mixed mock modular forms

open access: yesJournal of Inequalities and Applications, 2016
The number of strongly unimodal sequences of weight n is denoted by u ∗ ( n ) $u^{*}(n)$ . The generating functions for { u ∗ ( n ) } n = 1 ∞ $\{u^{*}(n)\}_{n=1}^{\infty}$ are U ∗ ( q ) = ∑ n = 1 ∞ u ∗ ( n ) q n $U^{*}(q)=\sum_{n=1}^{\infty}u^{*}(n)q^{n}$

Aloneness and the terms of detachment in West African migration

open access: yesJournal of the Royal Anthropological Institute, Volume 31, Issue 3, Page 699-716, September 2025.
In this article, I examine practices of social detachment among West African migrants in urban Ghana. Faced with pressures arising from expectations of reciprocity, especially from kin back home, some migrants exert considerable efforts to break, if temporarily, with relations of mutual recognition and support, entering what I term migratory aloneness.

Exploring the Characteristics of Δh Bivariate Appell Polynomials: An In-Depth Investigation and Extension through Fractional Operators

open access: yesFractal and Fractional
The objective of this article is to introduce the ∆h bivariate Appell polynomials ∆hAs[r](λ,η;h) and their extended form via fractional operators. The study described in this paper follows the line of study in which the monomiality principle is used to ...

Classes of hypercomplex polynomials of discrete variable based on the quasi-monomiality principle

open access: yes, 2014
With the aim of derive a quasi-monomiality formulation in the context of discrete hypercomplex variables, one will amalgamate through a Clifford-algebraic structure of signature $(0,n)$ the umbral calculus framework with Lie-algebraic symmetries.

Agropastoral possibilism and the trajectorial affordances of Danish inland heaths: a study of deep‐time entrapment Possibilisme agropastoral et affordances des trajectoires dans les landes de l'arrière‐pays danois : une étude des entraves dans le passé lointain

open access: yesJournal of the Royal Anthropological Institute, Volume 31, Issue 3, Page 850-873, September 2025.
History does not unfold along a single trajectory, and yet the socioecological configuration of landscapes may narrow the directions history can take. This article develops a framework for assessing the directionality of history in a (pre)historic heath landscape in Denmark.

On computing some special values of hypergeometric functions

open access: yes, 2014
The theoretical computing of special values assumed by the hypergeometric functions has a high interest not only on its own, but also in sight of the remarkable implications to both pure Mathematics and Mathematical Physics.

All‐in‐one, versatile and low‐cost experimental set‐up to implement environmental stochasticity in mesocosms (PiStoch)

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 9, Page 1955-1965, September 2025.
Abstract Environmental stochasticity in abiotic factors is inherent to ecosystems and is exacerbated by global change. However, experimental protocols typically cancel this factor by using cyclic or constant conditions, limiting the study of environmental variations.
