Rapid urbanisation, the interconnection of economies and growing dependence on technology makes modern society increasingly vulnerable to natural disasters. In case of earthquakes, the mitigation of seismic risk in urban and industrial area can be effectively accomplished by Earthquake Early Warning systems (EEWS), which performs real-time event detection and characterization, issues rapid aler...

Considerable evidence suggests that during the progression of complex diseases, the deteriorations are not necessarily smooth but are abrupt, and may cause a critical transition from one state to another at a tipping point. Here, we develop a model-free method to detect early-warning signals of such critical transitions, even with only a small number of samples. Specifically, we theoretically d...

Abstract Signal analysis and anomaly detection for water pollution early warning systems are important necessary. In view of the nonlinear volatile characteristics quality time series, this paper proposes a new method based on fluctuation feature analysis. The has two steps. First, series data used to calculate residuals between observed value predicted with long short-term memory (LSTM) networ...

At local emerging stock markets such as Korea, Hong Kong, Singapore and Taiwan, global institutional investors (GII) comprised of global mutual funds, offshore funds, and hedge funds play a key role and more often than not cause severe turmoil via massive selling. Thus, for the concerned local governments or private and institutional investors, it is quite necessary to monitor the behavior of G...

This study takes our country's unified construction of rapid response system of food safety as the goal, regarding the model of early warning of food safety as the breakthrough point, combined with the analysis of the features of the early warning of the network, exploring the integrated ideas of the early forecast and early warning system of food safety information in China, so as to construct...
