Effective Frequency Range and Jump Behavior of Horizontal Quasi-Zero Stiffness Isolator

Applied Sciences, 2023
The quasi-zero stiffness (QZS) isolator shows excellent characteristics of low-frequency vibration isolation. However, the jump behavior caused by the strong nonlinearity is a primary reason for the failure of QZS isolators.

Isolation of Cycles

Graphs and Combinatorics, 2020
For any graph $G$, let $ι_{\rm c}(G)$ denote the size of a smallest set $D$ of vertices of $G$ such that the graph obtained from $G$ by deleting the closed neighbourhood of $D$ contains no cycle. We prove that if $G$ is a connected $n$-vertex graph that is not a triangle, then $ι_{\rm c}(G) \leq n/4$. We also show that the bound is sharp. Consequently,
