Symbolic Methods Applied to a Class of Identities Involving Appell Polynomials and Stirling Numbers
MathematicsIn this paper, we present two symbolic methods, in particular, the method starting from the source identity, umbra identity, for constructing identities of s-Appell polynomials related to Stirling numbers and binomial coefficients.

The Genoeconomics of Impulsive Intertemporal Choice: A Critical Review
Journal of the Experimental Analysis of Behavior, Volume 126, Issue 1, July 2026.Abstract Dr. Warren Bickel tirelessly investigated delay discounting (DD), a behavioral economic index of impulsive decision making, as a determinant of numerous health outcomes. Among the factors that contribute to a person's level of DD, a burgeoning body of research has illuminated its genetic foundations and the extent to which it may be a ...

Riordan arrays associated with Laurent series and generalized Sheffer-type groups [PDF]
, 2011 A relationship between a pair of Laurent series and Riordan arrays is formulated. In addition, a type of generalized Sheffer groups is defined using Riordan arrays with respect to power series with non-zero coefficients.

Sheffer sequences with zeros on a line
Journal of Mathematical Analysis and ApplicationsWe extend a result of Bump et al. to show that a large family of Sheffer sequences has their zeros - up to perhaps a finite number of exceptions - on a vertical line. We connect a particular such sequence to the Riemann zeta function via a product representation of a scaled Mellin transform, analogously to the product decomposition of a Mellin ...

Representative policymakers? A behavioural experiment with French politicians
Economica, Volume 93, Issue 371, Page 930-961, July 2026.Abstract This study leverages an online behavioural experiment to analyse whether politicians' decisions align with citizens' preferences and with citizens' decisions within the same decision environment. We recruited 760 local politicians and 655 non‐politicians in France to participate as policymakers in a taxation‐redistribution game.

Seasonal Drought Timing Shapes Flowering Phenology Directly and Through Biotic Interactions
Ecology Letters, Volume 29, Issue 7, July 2026.The effects of drought on flowering depend on when drought occurs during the growing season. In experimental monocultures and mixtures, autumn drought delayed flowering onset whereas spring drought advanced flowering termination, with both reducing flowering duration through direct physiological effects and competition‐mediated interactions.

On a Biparametric Appell Extension: Analytical Properties and Structural Analysis
AxiomsThis paper introduces and investigates a novel two-parameter sequence, termed the biparametric Appell extension (B-App-Ex) and denoted by Bn(x;λ,α). Standard classical Appell sequences often lack sufficient structural parameters, which can limit their ...

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.

Philosophical Investigations, Volume 49, Issue 3, Page 300-315, July 2026.ABSTRACT According to most readers of the Tractatus, Wittgenstein's logic is empty or contentless, since it consists of tautologies that do not picture reality. This view, however, does not explain how and why Wittgenstein's ‘logic of depiction’ is transcendental (T, 4.015 and 6.13), especially given that Kant introduced transcendental logic through ...
