A Novel Heterogeneous Wireless Sensor Node Deployment Algorithm With Parameter-Free Configuration
IEEE Access, 2018 The deployment of wireless sensor nodes affects the WSN performance, such as the sensing coverage, the connectivity between sensor nodes, and the network lifetime.

The Stretch Factor of the Delaunay Triangulation Is Less Than 1.998
, 2013 Let $S$ be a finite set of points in the Euclidean plane. Let $D$ be a Delaunay triangulation of $S$. The {\em stretch factor} (also known as {\em dilation} or {\em spanning ratio}) of $D$ is the maximum ratio, among all points $p$ and $q$ in $S$, of the

Efficacy of Optically Pumped Magnetometers in Detecting Activity From the Cerebellar Cortex
Human Brain Mapping, Volume 47, Issue 5, 1 April 2026.We studied the utility of OPMs and conventional SQUID sensors in detecting cerebellar activity. Our results indicate clear benefits for OPMs in terms of sensitivity, lead‐field correlations between the cortex and the cerebellum, and total information, with these improvements already achievable with 102 triaxial OPM sensors covering the whole head ...

Design of adaptive unstructured grids using differential methods
Вестник КазНУ. Серия математика, механика, информатика, 2018 Adaptive generation of computational grids can improve the efficiency of mathematical modeling by increasing the accuracy of numerical approximations. The paper describes a method for constructing unstructured grids with adaptation based on differential ...

A Biophysical Approach to the Design of Networks of Communication Systems
Mathematical Methods in the Applied Sciences, Volume 49, Issue 5, Page 4539-4547, 30 March 2026.ABSTRACT Inspired by the growth dynamics of the protist Physarum polycephalum, we employ a formalism that describes adaptive, incompressible Hagen‐Poiseuille flows on channel networks to identify graphs connecting different nodes within Euclidean space. These graphs are either suboptimal or optimal relative to their length.

One machine, one minute, three billion tetrahedra
, 2018 This paper presents a new scalable parallelization scheme to generate the 3D Delaunay triangulation of a given set of points. Our first contribution is an efficient serial implementation of the incremental Delaunay insertion algorithm. A simple dedicated

Application of Discontinuity Layout Optimization to Metal Shells and Assemblies
International Journal for Numerical Methods in Engineering, Volume 127, Issue 5, 15 March 2026.ABSTRACT Discontinuity Layout Optimization (DLO) provides a computationally efficient means of determining collapse loads and associated failure mechanisms across a wide spectrum of plasticity problems. The classical DLO method has focused separately on in‐plane and out‐of‐plane plasticity.

EURASIP Journal on Advances in Signal Processing, 2002 We present one method for detecting defects on an inclined textured plane. This method uses a combination of a shape from texture (SFT) method with the Delaunay triangulation technique.

Advanced Science, Volume 13, Issue 17, 23 March 2026.Tumor evolution in lung adenocarcinoma is shaped by genetic alterations and spatial immune dynamics. By integrating whole‐exome sequencing, imaging mass cytometry, and spatial transcriptomics across two mouse models, this study reveals how mutational burden, immune infiltration, and cell–state interactions evolve during early and late carcinogenesis ...
