Learning Across the Divide: Understanding Knowledge Sharing Through Petrographic Analysis on Ceramics From the Rhine‐Meuse Delta During the Middle to Late Neolithic Transition (3400–2200 bce)

open access: yesArchaeometry, EarlyView.
ABSTRACT Vlaardingen (VL) communities on the Dutch West coast (3400–2200 bce) are part of a unique, long‐term continuity in the European Neolithic. Despite large‐scale changes in European populations during the Neolithic, the genomic diversity and cultural practices of VL communities can be retraced to the Mesolithic.

Real‐time by‐example texture synthesis and filtering using local statistics exchange

open access: yesComputer Graphics Forum, EarlyView.
Abstract Real‐time by‐example texture synthesis is used in interactive virtual worlds to generate the appearance of an unbounded surface from an exemplar texture with as few repetitions as possible. Currently, leading real‐time methods rely on a tiling and blending scheme which is known to synthesize well texture patterns with little spatial ...

On a class of norms generated by nonnegative integrable distributions

open access: yesDependence Modeling, 2019
We show that any distribution function on ℝd with nonnegative, nonzero and integrable marginal distributions can be characterized by a norm on ℝd+1, called F-norm. We characterize the set of F-norms and prove that pointwise convergence of a sequence of F-

Extending the Wasserstein metric to positive measures

open access: yes, 2023
We define a metric in the space of positive finite positive measures that extends the 2-Wasserstein metric, i.e. its restriction to the set of probability measures is the 2-Wasserstein metric. We prove a dual and a dynamic formulation and extend the gradient flow machinery of the Wasserstein space. In addition, we relate the barycenter in this space to

Establishing Shape Correspondences: A Survey

open access: yesComputer Graphics Forum, EarlyView.
Abstract Shape correspondence between surfaces in 3D is a central problem in geometry processing, concerned with establishing meaningful relations between surfaces. While all correspondence problems share this goal, specific formulations can differ significantly: Downstream applications require certain properties that correspondences must satisfy ...

Distributionally Robust Energy Optimization with Renewable Resource Uncertainty

open access: yesMathematics
With the increasing prevalence of intermittent power generation, the volatility, intermittency, and randomness of renewable energy pose significant challenges to the planning and operation of distribution networks.

Sharp asymptotic and finite-sample rates of convergence of empirical measures in Wasserstein distance

open access: yes, 2017
The Wasserstein distance between two probability measures on a metric space is a measure of closeness with applications in statistics, probability, and machine learning.

The Efficacy of Intracanal Medicaments Within the Regenerative Endodontic Procedures on Permanent Necrotic Immature Teeth: Systematic Review and Naïve Indirect‐Comparison Meta‐Analysis

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Objectives The objectives of this study were to estimate and compare the 1‐year clinical success rates of triple antibiotic paste (TAP), double antibiotic paste (DAP), calcium hydroxide (CH) within regenerative endodontic procedures (REPs) on permanent necrotic immature teeth.

On Metric Choice in Dimension Reduction for Fréchet Regression

open access: yesInternational Statistical Review, EarlyView.
Summary Fréchet regression is becoming a mainstay in modern data analysis for analysing non‐traditional data types belonging to general metric spaces. This novel regression method is especially useful in the analysis of complex health data such as continuous monitoring and imaging data.

A Comparative Review of Specification Tests for Diffusion Models

open access: yesInternational Statistical Review, EarlyView.
Summary Diffusion models play an essential role in modelling continuous‐time stochastic processes in the financial field. Therefore, several proposals have been developed in the last decades to test the specification of stochastic differential equations.
