Behavioural ecotoxicology, an “early warning” signal to assess environmental quality

BACKGROUND In this review, the position of behavioural ecotoxicology within the available means to assess the status of marine environments is described as filling the gap for the needed "early warning" signals. A few examples of studies performed since the 1960s are discussed to highlight the sensitivity of these approaches in investigating the effects of chemicals, including priority pollutan...

Information dissipation as an early-warning signal for the Lehman Brothers collapse in financial time series

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...

Slowing down as an early warning signal for abrupt climate change.

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...

Honeynet Clusters as an early Warning System for Production Networks

Due to the prevalence of distributed and coordinated Internet attacks, many researchers and network administrators study the nature and strategies of attackers. To analyze event logs, using intrusion detection systems and active network monitoring, Honeynets are being deployed to attract potential attackers in order to investigate their modus operandi. Our goal is to use Honeynet clusters as re...
