Social pollinators such as honey bees face attacks from predators not only at the nest, but also during foraging. Pollinating honey bees can therefore release alarm pheromones that deter conspecifics from visiting dangerous inflorescences. However, the effect of alarm pheromone and its chemical components upon bee avoidance of dangerous food sources remains unclear. We tested the responses of g...

Abstract The risk management of rainfall-induced landslides requires reliable rainfall thresholds to issue early warning alerts. practical application these often leads misclassifications, either false negative or positive, which induce costs for the society. Since missed-alarm (false negative) and false-alarm positive) cost may be significantly different, it is necessary find an optimal thresh...

Alarm signalling is of paramount importance to communication in all social insects. In termites, vibroacoustic and chemical alarm signalling are bound to operate synergistically but have never been studied simultaneously in a single species. Here, we inspected the functional significance of both communication channels in Constrictotermes cyphergaster (Termitidae: Nasutitermitinae), confirming t...

This paper, starting from the level of mobile communication network alarm management, comes up with the alarm types and the six-stage model. The paper also discusses the step of recessive maintenance and management from the perspective of mobile communication in terms of the effective control of network alarms, and also extends the network equipment alarm logic correlation to the logical level ...

When a chemical plant is abnormal state, an alarm system must provide useful information to operators as the second layer of independent protection layer. Therefore, a method of designing plant alarm system is important for plant safety. Because the plant is modified in the plant lifecycle, the alarm system for the plant should be properly managed through the plant lifecycle. To manage the chan...

Fifty six children aged from 6-16 years who wet their beds at night were entered into a controlled trial of two alarm devices: a traditional alarm using a wet sensor mat on the bed attached to an alarm bell out of reach of the child, and a mini alarm system incorporating a tiny perineal wet sensor attached to a small alarm worn on the child's clothing. A quota allocation system ensured comparab...

The problem of multivariate alarm analysis and rationalization is complex and important in the area of smart alarm management due to the interrelationships between variables. The technique of capturing and visualizing the correlation information, especially from historical alarm data directly, is beneficial for further analysis. In this paper, the Gaussian kernel method is applied to generate p...

Prey species possess numerous strategies to reduce predation. One tactic is to respond with antipredator behaviours when conspecific alarm cues are detected. The sea hare Aplysia californica defends itself from predators in many ways, one of which is releasing ink and opaline upon attack. Previous work showed that a mixture of ink and opaline from A. californica causes conspecifics to respond w...

warning that deadly new strains of tuberculosis, virtually untreatable using the drugs currently available, appear to be spreading across the globe, raising the spectre of a resurgence in a disease which for many generations has laid in the background, seemingly beaten, but which may now make a major comeback as a lethal new pathogen. The new strains are known as extreme drug-resistant TB or XD...
