Summary: This paper investigates intra-layer synchronization (ALS) and inter-layer synchronization (RLS) in multi-layer networks (MLNs) with different layer topologies and node-to-node inter-layer connections. Dynamic event-triggered (DET) control is introduced into the design of synchronization controllers in MLNs to reduce communication frequency. Sufficient conditions for ALS and RLS are derived using the Lyapunov functional method and appropriate DET controllers. The theoretical results show that the designed DET conditions in MLNs can further reduce triggering frequency compared to static event-triggered (SET) conditions and eliminate the Zeno phenomenon. Numerical simulations are provided to validate the theoretical results.

Summary: Nonmagnetic chiral crystals are a new type of materials that possess Kramers-Weyl Fermions due to the combination of structural chirality, spin-orbit coupling, and time-reversal symmetry. These materials exhibit unique Fermi surfaces with spin-orbit coupling-induced Chern gaps, leading to exotic transport and optical properties. This study investigates the electronic structure and transport properties of CdAs2, a recently discovered chiral material, using angle-resolved photoelectron spectroscopy and density functional theory. The results suggest that CdAs2 is a promising candidate for novel topological properties and provide valuable insights for the development of spintronic and optical devices based on chiral charges and nontrivial Chern numbers.

Summary: In chemistry, the theory of aromaticity or pi bond resonance is crucial for understanding the stability and properties of organic molecules. This study presents an analogue theory for sigma bond resonance in flat boron materials, allowing for the determination of two-center two-electron and three-center two-electron bond distributions without quantum calculations. Based on this theory, three rules are proposed for drawing Kekule-like bonding configurations and exploring properties of flat boron materials. Additionally, the theory is applied to explain the stability of neutral borophene with approximately 1/9 hole occupancy and the effect of charge doping on borophene's optimal hole concentration. This theory enhances our understanding of boron materials and facilitates the rational design of boron-based materials.

Summary: The air stability of BeO monolayer with and without vacancy defects was investigated using DFT calculations. The results show that BeO monolayers exhibit high structural and electronic stability even with Be vacancies when exposed to O2, N2, CO2 and H2O. O vacancies are not favorable in free-standing BeO monolayers and can be easily healed by H2O or CO2 adsorption. Due to their high stability, large band gap, and atomic flat surface, BeO monolayers are expected to be an ideal encapsulation material for 2D electronic devices.
