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...

Abstract In the process of cable transmission, existence air gap, tip, burr and other conditions will cause partial discharge phenomenon lead to insulation aging, which can affect safety power transmission. Partial detection detect early defects accurately, timely efficiently. It is an ideal method occurrence PD by ultrasonic wave by-product because it less affected electromagnetic interference...

In several biomedical domains, it would be interesting to monitor subjects over night time using wearable motion sensors and trigger an alarm if a specific movement has been detected by processing the accelerometer readings. In this paper, the authors describe an innovative architecture for such an alarm system in the context of epilepsy monitoring. The main ingredients of the proposed system a...
