Further remarks on extended umbral calculus [PDF]

open access: yes, 2001
summary:The paper deals with extensions of the finite operator calculus of G.-C. Rota called $\psi$-extensions which give a framework for corresponding quantum group investigations.

Defining and identifying relevant stakeholders to advance effective conservation

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
The challenge of defining stakeholders in environmental science and an approach for refining existing definitions. Abstract Stakeholder is a contested term that has spawned a multitude of ad hoc definitions. The ambiguity of these definitions has oftentimes impeded transdisciplinary research in environmental governance and conservation science because ...

Special Numbers and Polynomials Including Their Generating Functions in Umbral Analysis Methods

open access: yesAxioms, 2018
In this paper, by applying umbral calculus methods to generating functions for the combinatorial numbers and the Apostol type polynomials and numbers of order k, we derive some identities and relations including the combinatorial numbers, the Apostol ...

On a Novel Class of Special Polynomials: Central Bell-Based Type 2 Euler Polynomials Associated with Umbral Calculus

open access: yesContemporary Mathematics
In this work, the authors define the central Bell-based central factorial polynomials of the second kind and examine many of their fundamental formulae, properties, and relations, some of which are derived using the umbral calculus technique.

Evaluating Ballot Initiative Results for Adult‐Use Marijuana in Ohio: Understanding County‐Level Support

open access: yesPolitics &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%.

Foraging plasticity and physiological adaptations enable hummingbirds to subsist on dilute nectars

open access: yesFunctional 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.

More on deformed oscillator algebras and extended umbral calculus [PDF]

open access: yes, 2002
summary:This paper deals with $\varphi(q)$ calculus which is an extension of finite operator calculus due to Rota, and leading results of Rota's calculus are easily $\varphi$-extendable.

Acclimatisation duration, not just release type, drives post‐release settlement in a large‐scale carnivore reintroduction programme

open access: yesJournal 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 ...

Effect of Delta Operator on Umbral Composition in Finite Operator calculus [PDF]

open access: yes, 2016
The main objective of this paper is to propose the matrix representation of umbral composition and investigate the effect of delta operator on umbral composition by using the sequential representation of delta operator in finite operator ...
