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 ...

TABI: Tight and Balanced Interactive Atlas Packing

open access: yesComputer Graphics Forum, EarlyView.
Abstract Atlas packing is a key step in many computer graphics applications. Packing algorithms seek to arrange a set of charts within a fixed‐size atlas with as little downscaling as possible. Many packing applications such as content creation tools, dynamic atlas generation for video games, and texture space shading require on‐the‐fly interactive ...

On compound operators constructed with binomial and Sheffer sequences

open access: yesJournal of Numerical Analysis and Approximation Theory, 2003
In this note we consider a general compound approximation operator using binomial sequences and we give a representation for its corresponding remainder term. We also introduce a more general compound approximation operator using Sheffer sequences.

DiskScissors: Cutting Arbitrary‐Topology Solids for Bijective Mapping

open access: yesComputer Graphics Forum, EarlyView.
Abstract An algorithm for cutting solid objects in a topology‐controlled manner is presented. Concretely, given a loop on the object boundary, a disk‐topology cut surface bounded by the loop is constructed in the interior. In contrast to various previous approaches, both disk topology and conformance to the prescribed loop are ensured by construction ...

Embedding Optimization of Layouts via Distortion Minimization

open access: yesComputer Graphics Forum, EarlyView.
Abstract Given an embedding of a layout in the surface of a target mesh, we consider the problem of optimizing the embedding geometrically. Layout embeddings partition the surface into multiple disk‐like patches, making them particularly useful for parametrization and remeshing tasks, such as quad‐remeshing, since these problems can then be solved on ...

Approximation operators constructed by means of Sheffer sequences

open access: yesJournal 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

Mid‐infrared spectroscopy applied to a multi‐level cave system (Montmaurin, SW France): An innovative method for assessing sediment provenance

open access: yesSedimentology, EarlyView.
ABSTRACT Deciphering sediment provenance is essential to understand depositional patterns and dynamics. This question is particularly important in archaeological contexts to constrain the sedimentological history of unearthed material—an information critically needed, for example, to estimate the age of the deposits—or to apprehend sediment movement ...

The Genoeconomics of Impulsive Intertemporal Choice: A Critical Review

open access: yesJournal 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 ...

Representative policymakers? A behavioural experiment with French politicians

open access: yesEconomica, 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.

‘Logic Is Transcendental’: Content, Isomorphism and Intentionality in Wittgenstein's Logic of Depiction

open access: yesPhilosophical 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 ...
