Umbral nature of the Poisson random variables [PDF]
, 2001 Extending the rigorous presentation of the classical umbral calculus given by Rota and Taylor in 1994, the so-called partition polynomials are interpreted with the aim to point out the umbral nature of the Poisson random variables.

Politics &Policy, Volume 54, Issue 3, June 2026.ABSTRACT In the 2023 November election, Ohioans voted in favor of Issue 2—the Marijuana Legalization Initiative. The successful passing of this initiative at the ballot box made Ohio the 24th state and largest Republican voting state to adopt a recreational adult‐use marijuana policy. Issue 2 was voted in favor of by a margin of 57% to 43%.

An infinite dimensional umbral calculus [PDF]
, 2019 The aim of this paper is to develop foundations of umbral calculus on the space $\mathcal D'$ of distributions on $\mathbb R^d$, which leads to a general theory of Sheffer polynomial sequences on $\mathcal D'$.

Foraging plasticity and physiological adaptations enable hummingbirds to subsist on dilute nectars
Functional Ecology, Volume 40, Issue 5, Page 1475-1490, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Hummingbirds frequently feed on small volumes (<30 μL) of sucrose‐rich nectars. Climate change is expected to affect both the abundance and the concentrations of accumulated nectar.

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 ...

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.Our study highlights that when acclimatisation periods are too short, the substantial economic and logistical investment in soft‐release protocols may fail to deliver the expected conservation gains. Therefore, defining evidence‐based acclimatisation periods that are long enough to promote settlement, yet compatible with logistical constraints, may ...

Integration in the umbral calculus
Journal of Mathematical Analysis and Applications, 1980 AbstractThe adjointness between “multiplication” and “derivation” is a recurrent theme in Rota's umbral calculus. The subject of this paper is the companion adjointness between “division” and “integration.”

Space Weather, Volume 24, Issue 4, April 2026.Abstract The total solar eclipse on 8 April 2024 provided a unique opportunity to investigate the three‐dimensional (3‐D) ionospheric response under enhanced solar activity over North America. In this study, we processed high‐density GNSS observations from ∼1,700 stations to derive vertical total electron content and applied a multi‐term sinusoidal ...
