Advanced Functional Materials, EarlyView.In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

On the Laplacian spectral radius of a tree
Linear Algebra and its Applications, 2003 The Laplacian matrix of a graph is the difference of the diagonal matrix of its vertex degrees and its adjacency matrix. The Laplacian spectral radius of a graph is the largest eigenvalue of its Laplacian matrix. This paper gives upper bounds on the Laplacian spectral radius of trees, in terms of the size of a maximum matching in it, and the number of ...

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite
Advanced Functional Materials, EarlyView.The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Spectral radius of bipartite graphs
Linear Algebra and its Applications, 2015 Let k, p, q be positive integers with k < p < q+1. We prove that the maximum spectral radius of a simple bipartite graph obtained from the complete bipartite graph Kp,q of bipartition orders p and q by deleting k edges is attained when the deleting edges are all incident on a common vertex which is located in the partite set of order q.
