Impact on species' online attention when named after celebrities
Conservation Biology, Volume 38, Issue 2, April 2024.Abstract Celebrities can generate substantial attention and influence public interest in species. Using a large‐scale examination of publicly available data, we assessed whether species across 6 taxonomic groups received more page views on Wikipedia when the species was named after a celebrity than when it was not.

Identities arising from higher-order Daehee polynomial bases
Open Mathematics, 2015 Here we will derive formulas for expressing any polynomial as linear combinations of two kinds of higherorder Daehee polynomial basis. Then we will apply these formulas to certain polynomials in order to get new and interesting identities involving ...

A new discretization of the Euler equation via the finite operator theory [PDF]
Open Communications in Nonlinear Mathematical PhysicsWe propose a novel discretization procedure for the classical Euler equation, based on the theory of Galois differential algebras and the finite operator calculus developed by G.C. Rota and collaborators.

Umbral calculus and Euler polynomials
, 2012 In this paper, we study some properties of Euler polynomials arising from umbral calculus. Finally, we give some interesting identities of Euler polynomials using our results. Recently, Dere and Simsek have studied umbral calculus related to special polynomials (see[6]).

Spatiotemporal Characterization of Instability Indices Associated with Thunderstorms in Mexico
Advances in Meteorology, Volume 2024, Issue 1, 2024.Thunderstorms are known to have the potential to cause damage to the population. In Mexico, these weather events can bring threats such as lightning, hail, damaging winds, and even tornadoes. Various parameters and indices have been developed for mid‐latitude regions to improve forecasting and reduce the potential damage from thunderstorms; however ...

The classical umbral calculus: Sheffer sequences
, 2008 Following the approach of Rota and Taylor \cite{SIAM}, we present an innovative theory of Sheffer sequences in which the main properties are encoded by using umbrae. This syntax allows us noteworthy computational simplifications and conceptual clarifications in many results involving Sheffer sequences.

Approximation operators constructed by means of Sheffer sequences
Journal of Numerical Analysis and Approximation Theory, 2001 In this paper we introduce a class of positive linear operators by using the "umbral calculus", and we study some approximation properties of it. Let \( Q \) be a delta operator, and \(S\) an invertible shift invariant operator. For \(f\in C[0,1]\) we

Some remarks on Rota's umbral calculus
Indagationes Mathematicae (Proceedings), 1978 SummaryIt is shown that Rota's theory of Sheffer polynomials can be generalized to the quotient field of the ring of formal power series in 1x. As a special case we give some applications to the classical theories of factorial series and of Laguerre polynomials.
