Difficult arterial cannulation in children: is a near-infrared vascular imaging system the answer?

BACKGROUND Arterial cannulation is a common anaesthetic procedure that can be challenging and time-consuming in small children. By visualizing the position of the radial artery, near-infrared vascular imaging systems (NIRVISs) might be of assistance in arterial cannulation. The present study evaluates the effectiveness of an NIRVIS in arterial cannulation in infants. METHODS An observational ...

When the ICU is not the answer.

Multiagent learning is not the answer. It is the question

The article by Shoham, Powers, and Grenager called “If multi-agent learning is the answer, what is the question?” does a great job of laying out the current state of the art and open issues at the intersection of game theory and artificial intelligence (AI). However, from the AI perspective, the term “multiagent learning” applies more broadly than can be usefully framed in game theoretic terms....

Is pollen limited? The answer is blowin’ in the wind

Pollen from wind-pollinated trees has traditionally been assumed to be abundant and to travel long distances, resulting in extensive gene flow. However, recent empirical work by Knapp et al., genetic analysis by Sork et al., and theoretical models by Satake and Iwasa conclude that short-distance dispersal of limited pollen might be common and play an important role in causing the highly variabl...
