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...

Young workers of the ant Myrmica sabuleti (Hymenoptera: Formicidae) Meinert 1861 perceived nestmate alarm pheromone but did not display normal alarm behavior (orientation toward the source of emission, increased running speed). They changed their initial behavior when in the presence of older nestmates exhibiting normal alarm behavior. Four days later, the young ants exhibited an imperfect vers...

OBJECTIVES To identify which type of smoke alarm is most likely to remain working in local authority inner city housing, and to identify an alarm tolerated in households with smokers. DESIGN Randomised controlled trial. SETTING Two local authority housing estates in inner London. PARTICIPANTS 2145 households. INTERVENTION Installation of one of five types of smoke alarm (ionisation sens...

BACKGROUND After the implementation of narrowed oxygen saturation alarms, alarm frequency increased in the C.S. Mott Children's Hospital NICU which could have a negative impact on patient safety. The Joint Commission on the Accreditation of Healthcare Organizations issued a Sentinel Event Alert for hospitals in 2013 to improve alarm safety, resulting in a 2014 National Patient Safety Goal requi...

The quality of my daily awakening ritual changed dramatically a few months ago when I was exposed to the Timex Nature Sounds alarm clock. Prior to this, it had never occurred to me to use something other than the traditional buzzer-type alarm clock that I had had since 1986 because “it still worked.” While this was true, it worked by emitting a loud obnoxious sound that stimulated a fight or fl...

Alarm fatigue, a condition in which clinical staff become desensitized to alarms due to the high frequency of unnecessary alarms, is a major patient safety concern. Alarm fatigue is particularly prevalent in the pediatric setting, due to the high level of variation in vital signs with patient age. Existing studies have shown that the current default pediatric vital sign alarm thresholds are ina...

Because young ground squirrels are vulnerable to predation, selection would favor the early ability to respond to alarm calls. This requires discrimination of classes of alarm calls from each other as well as from non-alarm calls. Pre-emergent auditory experience may influence the development of discrimination. As a means of determining when Belding's ground squirrels (Spermophilus beldingi) ca...
