Optimizing higher-order network topology for synchronization of coupled phase oscillators [PDF]

open access: yesarXiv, 2021
Networks in nature have complex interactions among agents. One significant phenomenon induced by interactions is synchronization of coupled agents, and the interactive network topology can be tuned to optimize synchronization. The previous studies showed that the optimized conventional network with pairwise interactions favors a homogeneous degree ...

Different supramolecular interactions mediated by bromine atoms in the crystal structures of three anisole derivatives [PDF]

open access: yes, 2018
Three anisole building blocks featuring bishydroxymethyl or bisbromomethyl pendants have been analyzed with regard to their molecular structure and packing behaviour. A typical supramolecular pattern we found were C—H···π interactions responsible for the
