Miniature Soft Robot With Magnetically Reprogrammable Surgical Functions
Advanced Materials, EarlyView.Miniature soft robots have great prospects to revolutionize minimally invasive treatments. Here we present a miniature soft robot, which can be reprogrammed to perform five surgical functionalities with six‐degrees‐of‐freedom motions. This soft robot can prospectively make minimally invasive surgery considerably safer and painless, and enable ...

Distributed Tree Decomposition with Privacy [PDF]
, 2012 Tree Decomposition of Graphical Models is a well known method for mapping a graph into a tree, that is commonly used to speed up solving many problems. However, in a distributed case, one may have to respect the privacy rules (a subset of variables may have to be kept secret in a peer), and the initial network architecture (no link can be dynamically ...

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics
Advanced Materials, EarlyView.“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

P4-trees and substitution decomposition
Discrete Applied Mathematics, 1992 Cotrees for cographs (\(P_ 4\)-free graphs) are generalized to \(P_ 4\)- trees, which can be used to give the modular decomposition of the graph. A vertex addition algorithm is given to construct the \(P_ 4\)-tree of an \(n\)-vertex \(m\)-edge graph in \(O(n+m)\) time.

Phase Engineering of Atomically Precise Nanoclusters (APNCs) of Gold and Beyond
Advanced Materials, EarlyView.Engineering the structural phase of materials is of paramount importance for both fundamental research and practical applications. In this Review, we summarize the recent progress in controlling the phases of atomically precise nanoclusters (APNCs) of gold, silver and copper, as well as bimetallic systems. The phase‐enabled material properties of APNCs

Tree-decompositions, tree-representability and chordal graphs
Discrete Mathematics, 1988 The following assertions are shown to be equivalent, for any countable graph G: (1) G can be represented as the intersection graph of a family of subtrees of a tree; (2) G admits a tree-decomposition (Robertson/Seymour) into primes; (3) G is chordal, and G admits a simplicial tree-decomposition (Halin) into primes; (4) G is chordal, and neither of two ...
