Positive frequency-dependent selection (FDS) is a selection regime where the fitness of a phenotype increases with its frequency, and it is thought to underlie important adaptive strategies resting on signaling and communication. However, whether and how positive FDS truly operates in nature remains unknown, which hampers our understanding of signal diversity. Here, we test for positive FDS ope...

We carried out a Hungarian multicentre study to assess the frequency of the occurrence of warning symptoms preceding epileptic seizure. The data of 562 patients with epilepsy out of a total of 1124 were analysed on the basis of questionnaires filled in under standard conditions. About 50% of the patients experienced warning symptoms before a smaller or greater part of their seizures. Their appe...

This paper describes the simulation-based design methodology used in the eVADER project for the development of targeted acoustic warning devices for increased detectability of Hybrid and Electric Vehicles (HEVs) while, at the same time, reducing urban noise pollution compared to conventional acoustic pedestrian warning systems. A key component of this system is an external warning signal genera...

Vehicular ad hoc networks (VANETs) are expected to be used for the dissemination of emergency warning messages on the roads. The emergency warning messages such as post crash warning notification would require an efficient multi hop broadcast scheme to notify all the vehicles within a particular area about the emergency. Such emergency warning applications have low delay and transmission overhe...

The disaster that low temperature and spare sunlight occurred in North China is a major weather hazards to the sunlight greenhouse vegetable growing. The establishment of disaster warning system of low temperature and spare sunlight for greenhouse is of great significance to the disaster mitigation and prevention. According to the climate characteristics of Hebei Province and regional distribut...

In this study we examined the effect that reading a list of warning signs for suicide has on beliefs about suicide, including the belief that one can recognize a suicidal crisis. All participants read two sets of warning signs (with only the experimental group reading the suicide warning signs) and then answered questions concerning beliefs related to three health problems. Results indicate tha...

A series of bridge collapse take place in recent years, which cause people to pay more attention to bridge health monitoring and early warning. An intelligent health monitoring system for bridges is proposed after analyzing the functions and characteristics of the current bridge health monitoring system. The paper first introduce main functions of system and key technologies, then mainly introd...

Security systems frequently rely on warning messages to convey important information, especially when a machine is not able to assess a situation automatically. There is a significant body of work studying the effects of warning message design on users with numerous suggestions on how to optimise their effectiveness. Design guidelines and best practises help the developer to display urgent info...

The effect of warning regarding detection of malingering on the Rey Auditory Verbal Learning Test (RAVLT) was examined in this study. Sixty undergraduate students were randomly assigned to one of four conditions: malingerers, malingerers-with-warnings, warning-only, and control. An incentive that appeared differential, but was an actual constant reward, was offered to participants who could fak...
