On polynomials associated to Voronoi diagrams of point sets and crossing numbers [PDF]

Discrete Mathematics & Theoretical Computer Science
Three polynomials are defined for given sets $S$ of $n$ points in general position in the plane: The Voronoi polynomial with coefficients the numbers of vertices of the order-$k$ Voronoi diagrams of $S$, the circle polynomial with coefficients the ...

Optimizing Strategies for Non‐Invasive Prospection of Settlements in the Intertidal Zone: A Case Study From the Centre of the Drowned Medieval Village of Tolsende (Scheldt Estuary, the Netherlands)

Archaeological Prospection, EarlyView.
ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

The Nuclear Receptor Testicular Receptor 4 Orchestrates Cytoskeletal Organization in a G Protein Subunit Alpha 12/Rho‐Associated Protein Kinase–Dependent Manner to Promote Myofibroblast Differentiation and Tissue Fibrosis in Systemic Sclerosis

Arthritis &Rheumatology, EarlyView.
Objective Members of the superfamily of nuclear receptors have been implicated in inflammatory processes and pathologic tissue remodeling and have emerged as attractive targets for pharmaceutical intervention. However, the role of testicular receptor 4 (TR4; or Nr2c2) in fibroblast activation and rheumatologic diseases has not yet been investigated ...

An adaptive approach for generating Voronoi diagrams for residential areas containing adjacent polygons

International Journal of Digital Earth
This study proposes AVARA, an innovative adaptive Voronoi diagram algorithm explicitly designed for residential areas containing adjacent polygons. AVARA addresses the complex task of balancing computational efficiency and boundary position accuracy in ...

Queries with segments in Voronoi diagrams

Computational Geometry, 2000
In this paper we consider proximity problems in which the queries are line segments in the plane. We build a query structure that for a set of n points P can determine the closest point in P to a query segment outside the convex hull of P in O(log) time.

Design of Solar Energy Harvesting Reactor From 2D to 3D Structures for Solar Thermal Conversion

Carbon Innovation, EarlyView.
ABSTRACT Solar energy utilisation is pivotal for advancing sustainable and renewable energy solutions, yet the rational design of high‐efficiency photothermal conversion devices remains a critical challenge. This paper systematically examines the evolution of photothermal reactor architectures from two‐dimensional (2D) to 3D structures, emphasising ...

GPU-Based Parallel Euclidean Distance Transform Algorithm

Mathematics
Euclidean distance transform (EDT) often suffers from high computational complexity and limited processing efficiency, especially when applied to large-scale images. To address these challenges, this paper proposes a GPU-based parallel EDT algorithm. The

Measuring concentration with Voronoï diagrams: the study of possible biases

New Journal of Physics, 2012
In the context of turbulent flows laden with inertial particles, the accurate estimation of preferential concentration is particularly relevant. We have recently proposed to use Voronoï diagrams to estimate concentration fields from two-dimensional ...
