recommendations! Published in 2025 at "Physical review. E"

DOI: 10.1103/l5hk-kwyn

Abstract: Advancements in materials design and manufacturing have allowed for the production of ordered and disordered metamaterials with diverse properties. Hyperuniform two-phase heterogeneous materials, which anomalously suppress density fluctuations on large length scales compared to typical… read more here.

DOI: 10.1103/physreve.96.032909

Abstract: We introduce the concept of a "hyperuniformity disorder length" h that controls the variance of volume fraction fluctuations for randomly placed windows of fixed size. In particular, fluctuations are determined by the average number of… read more here.

DOI: 10.1109/tit.2024.3472448

Abstract: This article develops an analytical framework for studying information divergences and likelihood ratios associated with Poisson processes and point patterns on general measurable spaces. The main results include explicit analytical formulas for Kullback-Leibler divergences, Rényi… read more here.

DOI: 10.1109/tvcg.2024.3456168

Abstract: Points of interest on a map such as restaurants, hotels, or subway stations, give rise to categorical point data: data that have a fixed location and one or more categorical attributes. Consequently, recent years have… read more here.
