Acute Oxygen-Sensing Mechanisms [PDF]
New England Journal of Medicine, 2005 This review discusses recent advances in the understanding of the ways in which different organs detect and respond to acute changes in oxygen tension. A group of specialized tissues constitutes an oxygen-sensing system that responds rapidly to even minor changes in oxygen tension.

Nutrient-sensing mechanisms and pathways [PDF]
Nature, 2015 The ability to sense and respond to fluctuations in environmental nutrient levels is a requisite for life. Nutrient scarcity is a selective pressure that has shaped the evolution of most cellular processes. Different pathways that detect intracellular and extracellular levels of sugars, amino acids, lipids and surrogate metabolites are integrated and ...

Incentive Mechanisms for Community Sensing [PDF]
IEEE Transactions on Computers, 2014 Sensing and monitoring of our natural environment are important for sustainability. As sensor systems grow to a large scale, it will become infeasible to place all sensors under centralized control. We investigate community sensing, where sensors are controlled by self-interested agents that report their measurements to a center. The center can control

Mechanisms of Intragastric pH Sensing [PDF]
Current Gastroenterology Reports, 2010 Luminal amino acids and lack of luminal acidity as a result of acid neutralization by intragastric foodstuffs are powerful signals for acid secretion. Although the hormonal and neural pathways underlying this regulatory mechanism are well understood, the nature of the gastric luminal pH sensor has been enigmatic.
