DiskScissors: Cutting Arbitrary‐Topology Solids for Bijective Mapping
Computer 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 ...

The Characterization of Riordan Arrays and Sheffer-type Polynomial Sequences [PDF]
, 2012 Here we present a characterization of Sheffer-type polynomial sequences based on the isomorphism between the Riordan group and Sheffer group and the sequence characterization of Riordan arrays.

Embedding Optimization of Layouts via Distortion Minimization
Computer 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 ...

The classical umbral calculus: Sheffer sequences. [PDF]
, 2009 Following the approach of Rota and Taylor, 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

Certain results associated with hybrid relatives of the q-Sheffer sequences
Boletim da Sociedade Paranaense de Matemática, 2022 The intended objective of this paper is to introduce a new class of the hybrid q-Sheffer polynomials by means of the generating function and series definition. The determinant definition and other striking properties of these polynomials are established. Certain results for the continuous q-Hermite-Appell polynomials are obtained.

SharpEdge: Edge Feature Surface Reconstruction From Space Curves
Computer Graphics Forum, EarlyView.SharpEdge reconstructs surfaces with sharp features from sparse 3D curve networks. By estimating dual normals along curves, our method preserves ridges and corners while producing high‐quality meshes. Abstract Reconstructing high‐quality surfaces from sparse 3D space curves remains challenging, particularly when sharp feature edges are involved ...

Applied Psychology, Volume 75, Issue 4, August 2026.Abstract Extant research on autism at work remains scattered across areas of study, including organizational psychology, disability studies, and management, suggesting the need to systematically organize the body of knowledge. In this systematic review, I explore the small, yet growing body of literature focused on autism at work and integrate research

A note on Appell sequences, Mellin transforms and Fourier series [PDF]
, 2019 A large class of Appell polynomial sequences {p n (x)} n=0 8 are special values at the negative integers of an entire function F(s, x), given by the Mellin transform of the generating function for the sequence.

Sedimentology, Volume 73, Issue 5, Page 1722-1749, August 2026.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 ...
