The rainbow connection problem: mathematical formulations.

Ars Comb., 2016
Summary: The concept of rainbow connection was introduced by \textit{G. Chartrand} et al. [Math. Bohem. 133, No. 1, 85--98 (2008; Zbl 1199.05106)]. The rainbow connection number, \(\operatorname{rc}(G)\), of a connected graph \(G=(V,E)\) is the minimum number of colors needed to color the edges of \(E\), so that each pair of the vertices in \(V\) is ...

Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure

Advanced Engineering Materials, EarlyView.
Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

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.
