Innovation in emerging economies: Research on the digital economy driving high-quality green development
TL;DR: Wang et al. as mentioned in this paper measured the level of urban digital economy and high-quality green development in China, seeking to reveal the mechanisms and influences of the digital economy in a unified framework.

Stabilization of networked switched linear systems: An asynchronous switching delay system approach
TL;DR: This paper rewrite the original networked switched systems by sampled asynchronous switched systems with time-varying delays by giving the co-design conditions on both the switching signal and the controllers which depend on the sampling time, the upper bound of network-induced delays, and the asynchronous occurring frequency.

Delay Margin of Low-Order Systems Achievable by PID Controllers
TL;DR: This paper develops explicit expressions of the exact delay margin and its upper bounds achievable by a PID controller for low-order delay systems, notably the first- and second-order unstable systems with unknown constant and possibly time-varying delays.

Explicit bounds for guaranteed stabilization by PID control of second-order unstable delay systems
TL;DR: This paper derives explicit lower bounds on the delay margin of second-order unstable delay systems achievable by PID control, which provide a priori a guaranteed range of delay values over which a second- order delay plant can be stabilized by a PID, and more generally, a finite-dimensional LTI controller.

Bounds on Delay Consensus Margin of Second-Order Multiagent Systems With Robust Position and Velocity Feedback Protocol
TL;DR: This paper considers second-order agents with unstable poles, which communicate over an undirected network topology, and derive explicit bounds on the delay consensus margin, and shows that the consensuability robustness of such unstable agents depends on the pole locations of the agents, as well as on the eigenratio of the network graph.
