The Evolution of Warning Signals
Nature, 1998Warning coloration signals are a familiar and conspicuous phenomenon in nature. However, the fundamental question of how warning signals initially evolved remains unanswered. For an unpalatable prey to evolve a signal to indicate its unprofitability, a rare and conspicuous mutant in a population of unpalatable cryptic prey must overcome a double ...

Early warning signals for psychopathology
2024 IEEE Workshop on Complexity in Engineering (COMPENG)Many real-world phenomena share a common feature: the potential for sudden and difficult to reverse transitions into less desirable states. This applies to a wide range of domains, from ecosystems to social structures. The theory of dynamical systems has identified early warning signals (EWSs) that can precede these so-called critical transitions ...

Transportation Research Record: Journal of the Transportation Research Board, 2009
A driver approaching a signalized intersection at which the light has turned yellow must make a decision whether to stop or proceed. A signal that is properly timed will generally provide an opportunity for a safe and legal maneuver. As approach speeds increase, however, executing a safe maneuver becomes more difficult.

Early-warning signals for critical transitions
Nature, 2009Complex dynamical systems, ranging from ecosystems to financial markets and the climate, can have tipping points at which a sudden shift to a contrasting dynamical regime may occur. Although predicting such critical points before they are reached is extremely difficult, work in different scientific fields is now suggesting the existence of generic ...

<div class="htmlview paragraph">There is opportunity for the exercise of considerable ingenuity and mechanical skill in developing automobile signaling apparatus, but the basis of any system or appliance of this nature that is destined to meet with lasting success is quite as much a matter of psychology as mechanics.

Aspects of FHR Tracings as Warning Signals
Clinical Obstetrics and Gynecology, 1986We have reviewed several different groups of common clinical problems with an eye toward their effects on FHR tracings. Although argument exists in the literature concerning the universal applicability of continuous EFM, most authors agree that continuous EFM is desirable, if not imperative, within these subgroups.

Early Warning Signals for War in the News
SSRN Electronic Journal, 2012Abstract There have been more than 200 wars since the start of the 20th century, leading to about 35 million battle deaths. However, efforts at forecasting conflicts have so far performed poorly for lack of fine-grained and comprehensive measures of geopolitical tensions.

Warnings That Signal Serious Illness in Children
Journal of Pediatric Nursing, 2011INFECTION IS AN important source of mortality in children in developed countries. In children aged 1–4 years, infections account for 20% of childhood deaths (Confidential Enquiry intoMaternalandChildHealth,2008).Indevelopedcountries, every child will come to his or her health care provider, on average, more than once a year with the symptoms of an ...
