New AI‐Assisted Approach for Expanding the Solution Space: Application to Lattice Structure Design
This work introduces an innovative framework for designing structured materials by ex panding the design space through reparameterization of qualitative variables into continuous structural descriptors. Combined with machine‐learning‐based prediction and multi‐objective optimization, the approach enables the discovery of novel lattice architectures ...

Geometric RAC Simultaneous Drawings of Graphs
In this paper, we study the geometric RAC simultaneous drawing problem: Given two planar graphs that share a common vertex set, a geometric RAC simultaneous drawing is a straight-line drawing in which each graph is drawn planar, there are no edge ...

Additive Manufacturing of Alumina‐Reinforced Elastomers
Vat‐photopolymerized elastomers reinforced with platelet‐shaped alumina exhibited preferential orientation, reduced porosity, and significantly enhanced mechanical performance. A 3 wt% platelet loading increased tensile strength from 12.4 to 45.7 MPa, highlighting the critical role of filler morphology in elastomeric VPP composites.

Given four distinct vertices in a 4-connected planar graph \(G\), we characterize when the graph \(G\) contains a \(K_4\)-subdivision with the given vertices as its degree three vertices. This result implies the following conjecture of Robertson and Thomas: a 5-connected planar graph has no \(K_4\)-subdivision with specified degree three vertices, if ...

We study straight-line drawings of graphs where the vertices are placed in convex position in the plane, i.e., convex drawings. We consider two families of graph classes with convex drawings: outer $k$-planar graphs, where each edge is crossed by at ...

During creep of a single‐crystal Ni‐based superalloy, the overall crystal orientation is observed to remain constant while the microstructure evolves. Despite the lack of macroscopic rotation, small (<1°) rotations are observed on the submicron size scale and are accommodated by counteracting rotations over the scale of several micrometers.

Algorithm and Experiments in Testing Planar Graphs for Isomorphism
We give an algorithm for isomorphism testing of planar graphs suitable for practical implementation. The algorithm is based on the decomposition of a graph into biconnected components and further into SPQR-trees.

Abstract Abstract We generalize the idea of extended triangles of a graph G by considering a family of completes of G instead of the clique family of G. We characterize Helly and 3 - Helly Planar Graphs using extended triangles. We prove that if a planar graph is a clique graph then any one of its extended triangles is a clique graph.
