Evidence for Drop-Like Nuclear Deformation in Sheared Endothelial Monolayers. [PDF]
SmallPhysiological shear stress smoothens endothelial monolayers by selectively eliminating less‐spread cells with tall, wrinkled nuclei. Nuclear volume and surface area remain constant, consistent with drop‐like deformation governed by geometric constraints.

Multi-Robot Formation Control Based on CVT Algorithm and Health Optimization Management
Applied Sciences, 2022 In view of the low formation redundancy in the traditional rigid formation algorithm and its difficulty in dynamically adapting to the external environment, this study considers the use of the CVT (centroidal Voronoi tessellation) algorithm to control ...

GPU-Assisted Computation of Centroidal Voronoi Tessellation [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2011 Centroidal Voronoi tessellations (CVT) are widely used in computational science and engineering. The most commonly used method is Lloyd's method, and recently the L-BFGS method is shown to be faster than Lloyd's method for computing the CVT. However, these methods run on the CPU and are still too slow for many practical applications.

Exact Voronoi diagram for topographic spatial analysis
GIScience & Remote Sensing, 2023 The Voronoi diagram (VD) is a fundamental geo-computing structure that has crucial applications. Computing this structure on a topographic surface requires having every point clustered on the geodesic distances, and thus the same challenging task as the ...

Non-Obtuse Remeshing with Centroidal Voronoi Tessellation [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2016 We present a novel remeshing algorithm that avoids triangles with small (acute) angles and those with large (obtuse) angles. Our solution is based on an extension of Centroidal Voronoi Tesselation (CVT). We augment the original CVT formulation with a penalty term that penalizes short Voronoi edges, while the CVT term helps to avoid small angles.
