A note on harmonic numbers, umbral calculus and generating functions [PDF]
, 2007 We use methods of umbral calculus and algebraic nature to make some progress in the theory of generating functions involving harmonic numbers. We derive old and new results on generating functions in a fairly simple way and show that the method can be ...

Diabetes‐Related Distress in Spanish Adults: Clinical, Sociodemographic and Psychosocial Correlates
Diabetes/Metabolism Research and Reviews, Volume 42, Issue 3, March 2026.ABSTRACT Introduction Diabetes‐related distress refers to the emotional strain experienced by individuals who live with diabetes and face continuous demands of treatment and self‐management. Elevated distress is associated with poor adherence, impaired metabolic control, and diminished quality of life.

The Hour that Never Comes and the Time that Remains
Journal of Analytical Psychology, Volume 71, Issue 1, Page 123-143, February 2026.Abstract This essay proposes a symbolic and clinical investigation of psychic temporality through two archetypal experiences of time: the hour that never comes and the time that remains. Drawing on analytical psychology, trauma theory and aesthetic philosophy, text explores how certain forms of suffering resist chronological resolution and persist as ...

A Class of Sheffer Sequences of Some Complex Polynomials and Their Degenerate Types
Mathematics, 2019 We study some properties of Sheffer sequences for some special polynomials with complex Changhee and Daehee polynomials introducing their complex versions of the polynomials and splitting them into real and imaginary parts using trigonometric polynomial ...

On λ-linear functionals arising from p-adic integrals on Z p $\mathbb{Z}_{p}$
Advances in Difference Equations, 2021 The aim of this paper is to determine the λ-linear functionals sending any given polynomial p ( x ) $p(x)$ with coefficients in C p $\mathbb{C}_{p}$ to the p-adic invariant integral of P ( x ) $P(x)$ on Z p $\mathbb{Z}_{p}$ and also to that of P ( x 1 + ⋯

The Umbral Calculus of Symmetric Functions
Advances in Mathematics, 1996 The author develops an umbral calculus for the symmetric functions in an infinite number of variables. This umbral calculus is analogous to Roman-Rota umbral calculus for polynomials in one variable, see \textit{S. M. Roman} and \textit{G.-C. Rota} [Adv. Math. 27, 95-188 (1978; Zbl 0375.05007)].

Recursive matrices and umbral calculus
Journal of Algebra, 1982 Two major objectives can be seen to guide much recent work in enumeration: (1) to single out a limited variety of recurrences for numerical sequences which will encompass counting problems of wide-enough type; (2) to recover from empirical data an underlying set-theoretic structure which would reveal the source of the given recursion.

Identifying Key Biodiversity Areas Based on Distinct Genetic Diversity
Molecular Ecology Resources, Volume 26, Issue 2, February 2026.ABSTRACT Key Biodiversity Areas (KBAs) are sites that contribute significantly to the global persistence of biodiversity. Distinct genetic diversity has been introduced as one of the metrics to estimate whether a site holds a threshold proportion of a species' global genetic diversity during the KBA identification process.

Heisenberg algebra, umbral calculus and orthogonal polynomials [PDF]
, 2008 Umbral calculus can be viewed as an abstract theory of the Heisenberg commutation relation [(P) over cap,(M) over cap]=1. In ordinary quantum mechanics, (P) over cap is the derivative and (M) over cap the coordinate operator.

Key drivers of at‐vessel mortality in demersal sharks
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Chondrichthyans are highly vulnerable to fisheries overexploitation, and postcapture mortality poses a significant threat to most species. Global bycatch mitigation guidelines recommend adopting hierarchical decision‐making approaches tailored to species‐specific vulnerabilities and socioeconomic and regulatory contexts.
