Study on the Functions and Characteristics of Interfaces in CBTC [PDF]

2009 5th International Conference on Wireless Communications, Networking and Mobile Computing, 2009
Based on the analysis of three kinds of interfaces, this study discusses the application of interfaces technology on train-borne automatic train control systems. It proposes an interface system design for a train-borne CBTC (Communication Based Train Control) system. We study the interfaces functions and characteristics on physical attributes, protocol

Temporal Interference Stimulation Modulates Resting State Functional Connectivity of Motor Circuit in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Transcranial temporal interference stimulation (TIs) targeting the subthalamic nucleus (STN) is a novel noninvasive neuromodulation approach with potential to improve motor symptoms in Parkinson's disease (PD). However, its underlying neuroimaging mechanisms remain unclear.

Graph neural network‐based attack prediction for communication‐based train control systems

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract The Advanced Persistent Threats (APTs) have emerged as one of the key security challenges to industrial control systems. APTs are complex multi‐step attacks, and they are naturally diverse and complex. Therefore, it is important to comprehend the behaviour of APT attackers and anticipate the upcoming attack actions.
