Optimizing Attention and Cognitive Control Costs Using Temporally-Layered Architectures [PDF]
Neural Computation, 1-30 (2024), 2023 The current reinforcement learning framework focuses exclusively on performance, often at the expense of efficiency. In contrast, biological control achieves remarkable performance while also optimizing computational energy expenditure and decision frequency.

An Information Theoretical Analysis of Kinase Activated Phosphorylation Dephosphorylation Cycle [PDF]
IEEE Transactions on NanoBioscience, Volume 11, Issue 3, pp. 289 -
295 (2012), 2011 Signal transduction, the information processing mechanism in biological cells, is carried out by a network of biochemical reactions. The dynamics of driven biochemical reactions can be studied in terms of nonequilibrium statistical physics. Such systems may also be studied in terms of Shannon's information theory.

The biology of energy expenditure [PDF]
Journal of Experimental Biology, 2011 One of the great achievements of the biological sciences in the 20th century was the elucidation of the pathways and processes involved in energy metabolism. Concepts now considered fundamental to biology emerged, as the individual reactions of the major pathways were identified and the enzymes ...

Should I take a walk? Estimating Energy Expenditure from Video Data [PDF]
arXiv, 2022 We explore the problem of automatically inferring the amount of kilocalories used by human during physical activity from his/her video observation. To study this underresearched task, we introduce Vid2Burn -- an omni-source benchmark for estimating caloric expenditure from video data featuring both, high- and low-intensity activities for which we ...

Glucagon Regulation of Energy Expenditure [PDF]
International Journal of Molecular Sciences, 2019 Glucagon’s ability to increase energy expenditure has been known for more than 60 years, yet the mechanisms underlining glucagon’s thermogenic effect still remain largely elusive. Over the last years, significant efforts were directed to unravel the physiological and cellular underpinnings of how glucagon regulates energy expenditure.

Detection of thermogenesis in rodents in response to anti-obesity drugs and genetic modification
Frontiers in Physiology, 2013 Many compounds and genetic manipulations are claimed to confer resistance to obesity in rodents by raising energy expenditure. Examples taken from recent and older literature, demonstrate that such claims are often based on measurements of energy ...

Accuracy of Heart Rate Watches: Implications for Weight Management. [PDF]
PLoS ONE, 2016 BACKGROUND:Wrist-worn monitors claim to provide accurate measures of heart rate and energy expenditure. People wishing to lose weight use these devices to monitor energy balance, however the accuracy of these devices to measure such parameters has not ...
