Scheduling Sensors for Guaranteed Sparse Coverage [PDF]
, 2009 Sensor networks are particularly applicable to the tracking of objects in motion. For such applications, it may not necessary that the whole region be covered by sensors as long as the uncovered region is not too large. This notion has been formalized by

Periodic boundary conditions on the pseudosphere
, 2007 We provide a framework to build periodic boundary conditions on the pseudosphere (or hyperbolic plane), the infinite two-dimensional Riemannian space of constant negative curvature.

Rethinking Collinearity in Self‐Organizing Maps: Evidence From Geophysical Data Classification
Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.Abstract This study examines the impact of collinearity on unsupervised machine learning algorithms (UMLAs), specifically Self‐Organizing Maps (SOMs), for detecting lithological boundaries in geophysical data. Using a multi‐scale experimental framework that includes bivariate isotropic clusters, geologically complex Noddy simulations, and real‐world ...

Entropic Stabilization of Tunable Planar Modulated Superstructures
, 2011 Self-assembling novel ordered structures with nanoparticles has recently received much attention. Here we use computer simulations to study a two-dimensional model system characterized by a simple isotropic interaction that could be realized with ...

Anisotropic Cellular Forces Drive Hexagonal‐to‐Tetragonal Tiling Transitions in the Drosophila Eye
Development, Growth &Differentiation, Volume 68, Issue 3, April 2026.ABSTRACT Tile patterns are fundamental organizational principles of multicellular epithelial tissues. The Drosophila compound eye provides a striking example, in which ommatidia are arranged in a highly regular hexagonal lattice, while tetragonal patterns emerge in specific small‐eye mutants.

Lozenge Tilings of Hexagons with Central Holes and Dents [PDF]
The Electronic Journal of Combinatorics, 2020 Ciucu proved a simple product formula for the tiling number of a hexagon in which a chain of equilateral triangles of alternating orientations, called a `fern', has been removed from the center (Adv. Math. 2017). In this paper, we present a multi-parameter generalization of this work by giving an explicit tiling enumeration for a hexagon with three ...

Advanced Functional Materials, Volume 36, Issue 23, 19 March 2026.This study introduces a novel multi‐scale scaffold design using L‐fractals arranged in Archimedean tessellations for tissue regeneration. Despite similar porosity, tiles display vastly different tensile responses (1–100 MPa) and deformation modes. In vitro experiments with hMSCs show geometry‐dependent growth and activity. Over 55 000 tile combinations
