Chromatic numbers of algebraic hypergraphs [PDF]
Combinatorica, 2016 A k-uniform hypergraph is algebraic if its vertex set is n-dimensional Euclidean space, for some n, and its hyperedge set is defined from the zero set of some polynomial. The chromatic numbers of all algebraic hypergraphs are determined, provided they are infinite.

The Chromatic Number of Random Intersection Graphs
Discussiones Mathematicae Graph Theory, 2017 We study problems related to the chromatic number of a random intersection graph G (n,m, p). We introduce two new algorithms which colour G (n,m, p) with almost optimum number of colours with probability tending to 1 as n → ∞. Moreover we find a range of

Photothermomechanically Efficient, Low‐Cost, High‐Cycle‐Life, Hybrid MXene‐Polymer Actuators
Advanced Materials Technologies, EarlyView.The addition of MXenes to elastomer‐plastic‐paper films enables the creation of easily prepared actuators that are scalable for small robotic applications. Known as MXene‐polymer Trilayer Actuators (MPTAs), they bend from UV light. Their usefulness is demonstrated through kirigami‐inspired flower‐shaped art design, parallel manipulator for waveguiding,

A Degradable Device for Sustainable Capillary Blood Sampling
Advanced Materials Technologies, EarlyView.The device features a compostable 3D‐printed storage compartment for liquid blood collection and a degradable, poly(ɛ‐caprolactone)‐coated magnesium microneedle patch hidden within a suction cup. Manual compression deploys the MNs, creating small skin punctures, and the subsequent release of compression generates the negative pressure required for ...

The Chromatic Number of Random Regular Graphs
, 2004 Given any integer d >= 3, let k be the smallest integer such that d < 2k log k. We prove that with high probability the chromatic number of a random d-regular graph is k, k+1, or k+2, and that if (2k-1) \log k < d < 2k \log k then the chromatic number is
