Abstract Scientific ideas are often expressed as mathematical equations. Understanding the contained within these equations requires making sense of both embedded mathematics knowledge and scientific knowledge. Students who can engage in this type blended sensemaking more successful at solving novel or complex problems with However, students tend to rely on algorithmic/procedural approaches str...

The pull of Software-Defined Network- ing (SDN) is magnetic. There are few in the networking community who have escaped its impact. As the benefits of network visibility and network device programmability are discussed, the question could be asked as to who exactly will benefit? Will it be the network operator or will it, in fact, be the network intruder? As SDN devices and systems hit the mark...

Objective: The objective of this study was to test whether properties of 1-s segments of spontaneous scalp EEG activity can be used to automatically distinguish the awake state from the anesthetized state in patients undergoing general propofol anesthesia. Methods: Twenty five channel EEG was recorded from 10 patients undergoing general intravenous propofol anesthesia with remifentanil during a...

BACKGROUND There is little evidence about the effects of environmental interventions on population levels of physical activity. Major transport projects may promote or discourage physical activity in the form of walking and cycling, but researching the health effects of such "natural experiments" in transport policy or infrastructure is challenging. METHODS Case study of attempts in 2004-2005...

A recent international consensus conference1 published in 2007 proposed to categorize ventilated patients into 3 groups, based on the difficulty and duration of the weaning process: “simple weaning” (group 1) includes patients who succeed the first weaning trial and are extubated without difficulty, “difficult weaning” (group 2) includes patients who fail the first weaning trial and require up ...
