Different power quality (PQ) disturbance sources can have major impacts on the power supply grid. This study proposes, for the first time, an early warning approach to identifying PQ problems and providing early warning prompts based on the monitored data of PQ disturbance sources. To establish a steady-state power quality early warning index system, the characteristics of PQ disturbance source...

■ In the early 1950s, the threat of manned bombers carrying nuclear weapons across the arctic region was of paramount concern in continental defense. The 1952 Summer Study at MIT recommended the development of an earlywarning radar line across the northern reaches of Alaska and Canada, from Cape Lisburne on the northwest corner of Alaska to Cape Dyer on Baffin Island on the east coast of Canada...

We introduce deep learning time-series forecasting for gravitational wave detection of binary neutron star mergers. This method enables the identification these signals in real advanced LIGO data up to 30 seconds before merger. When applied GW170817, our identifies presence this signal 10 novel approach requires a single GPU inference, and may be used as part an early warning system time-sensit...

Against the backdrop of increasingly serious global climate change and the development of the low-carbon economy, the coordination between energy consumption carbon emissions (ECCE) and regional population, resources, environment, economy and society has become an important subject. In this paper, the research focuses on the security early warning of ECCE in Hebei Province, China. First, an ass...

In financial markets, participants locally optimize their profit which can result in a globally unstable state leading to a catastrophic change. The largest crash in the past decades is the bankruptcy of Lehman Brothers which was followed by a trust-based crisis between banks due to high-risk trading in complex products. We introduce information dissipation length (IDL) as a leading indicator o...

In the Earth's history, periods of relatively stable climate have often been interrupted by sharp transitions to a contrasting state. One explanation for such events of abrupt change is that they happened when the earth system reached a critical tipping point. However, this remains hard to prove for events in the remote past, and it is even more difficult to predict if and when we might reach a...

Endothelial dysfunction (ED) refers to a spectrum of pathophysiological changes in the vascular endothelium that ultimately results in a loss of vascular homeostasis. Traditional cardiovascular risk factors (e.g. diabetes mellitus, smoking, dyslipidaemia and hypertension) are all associated with the development of ED via sustained and harmful effects, mediated by circulating stimuli such as pro...

Drought information systems have multiple sub-systems which include an integrated risk assessment, communication and decision support system of which early warning is a central component and output. There are numerous drought systems warning systems being implemented at different scales of governance from the international to the community. An early warning system is much more than a forecast-i...
