The Activation-Relaxation Technique : ART nouveau and kinetic ART [PDF]
, 2012 The evolution of many systems is dominated by rare activated events that occur on timescale ranging from nanoseconds to the hour or more. For such systems, simulations must leave aside the full thermal description to focus specifically on mechanisms that

Energy expenditure of nonexercise activity [PDF]
The American Journal of Clinical Nutrition, 2000 We found recently that changes in nonexercise activity thermogenesis (NEAT) mediate resistance to weight gain with overfeeding in sedentary adults. A potentially important, yet seldom investigated, component of NEAT is the energy expenditure of fidgeting-like activities.Our goal was to measure changes in energy expenditure with fidgeting-like ...

Phosphorylation by Akt within the ST loop of AMPK-α1 down-regulates its activation in tumour cells [PDF]
, 2014 The insulin/IGF-1 (insulin-like growth factor 1)-activated protein kinase Akt (also known as protein kinase B) phosphorylates Ser487 in the ‘ST loop’ (serine/threonine-rich loop) within the C-terminal domain of AMPK-a1 (AMP-activated protein kinase-a1 ...
