Mechanical Properties of Architected Polymer Lattice Materials: A Comparative Study of Additive Manufacturing and CAD Using FEM and µ‐CT

Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.
This study examines how pore shape and manufacturing‐induced deviations affect the mechanical properties of 3D‐printed lattice materials with constant porosity. Combining µ‐CT analysis, FEM, and compression testing, the authors show that structural imperfections reduce stiffness and strength, while bulk material inhomogeneities probably enhance ...

Spherical Layout Implementation using Centroidal Voronoi Tessellations

, 2009
The 3D tree visualization faces multiple challenges: the election of an appropriate layout, the use of the interactions that make the data exploration easier and a metaphor that helps in the process of information understanding. A good combination of these elements will result in a visualization that effectively conveys the key features of a complex ...

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.

When Proximity Falls Short: Inequalities in Commuting and Accessibility by Public Transport in Santiago, Chile

Geographical Analysis, Volume 58, Issue 2, April 2026.
ABSTRACT Traditional measures of urban accessibility often rely on static models or survey data. However, location information from mobile networks enables large‐scale, dynamic analyses of how people navigate cities. In this study, we employ eXtended Detail Records (XDRs) from mobile phone activity to analyze commuting patterns and accessibility ...

Bayesian Inference for Spatially‐Temporally Misaligned Data Using Predictive Stacking

Environmetrics, Volume 37, Issue 2, March 2026.
ABSTRACT Air pollution remains a major environmental risk factor that is often associated with adverse health outcomes. However, quantifying and evaluating its effects on human health is challenging due to the complex nature of exposure data. Recent technological advances have led to the collection of various indicators of air pollution at increasingly

A calibration‐less, bonded‐sphere model for highly deformable particle systems in a discrete element method framework

AIChE Journal, Volume 72, Issue 2, February 2026.
Abstract Here, we introduce a calibration‐less bonded‐sphere model to describe three‐dimensional, linear elastic, highly deformable particles. Voronoi tessellation is used to partition a particle into multiple sub‐spheres, generating a virtual bond network that mimics the mechanical properties of the original particle.

Conformational dynamics in insulin receptor kinase reveal a type III allosteric pocket

Protein Science, Volume 35, Issue 2, February 2026.
Abstract Allosteric modulation is a promising strategy for selective kinase inhibition, yet structural insights into allosteric pockets remain limited across the human kinome. In this work, we present comprehensive characterization of a type III allosteric pocket in the insulin receptor kinase (IRK), integrating structural, conformational, and ...
