Dynamical compensation in physiological circuits
Molecular Systems Biology, 2016 Biological systems can maintain constant steady‐state output despite variation in biochemical parameters, a property known as exact adaptation. Exact adaptation is achieved using integral feedback, an engineering strategy that ensures that the output of ...

Physiological noise compensation in gradient-echo myelin water imaging
NeuroImage, 2015 In MRI, physiological noise which originates from cardiac and respiratory functions can induce substantial errors in detecting small signals in the brain. In this work, we explored the effects of the physiological noise and their compensation methods in gradient-echo myelin water imaging (GRE-MWI).

Hybrid dysfunction and physiological compensation in gene expression. [PDF]
Molecular Biology and Evolution, 2015 The formation of new species is often a consequence of genetic incompatibilities accumulated between populations during allopatric divergence. When divergent taxa interbreed, these incompatibilities impact physiology and have a direct cost resulting in reduced hybrid fitness.

The Behavior-Physiology Nexus: Behavioral and Physiological Compensation Are Relied on to Different Extents between Seasons [PDF]
Physiological and Biochemical Zoology, 2015 Environmental variability occurring at different timescales can significantly reduce performance, resulting in evolutionary fitness costs. Shifts in thermoregulatory behavior, metabolism, and water loss via phenotypic plasticity can compensate for thermal variation, but the relative contribution of each mechanism and how they may influence each other ...

Anatomical and Physiological Considerations in Vestibular Dysfunction and Compensation [PDF]
Seminars in Hearing, 2009 Sensory information from the vestibular, visual, and somatosensory/proprioceptive systems are integrated in the brain in complex ways to produce a final motor output to muscle groups for maintaining gaze, head and body posture, and controlling static and dynamic balance.

Effects of sodium chloride on circadian period and temperature compensation of KaiC phosphorylation [PDF]
Scientific ReportsThe circadian clock is an internal timekeeping system that generates ~ 24-h cycles in physiology and behavior, maintaining a remarkably consistent period across physiological conditions and temperature1.

Multidimensional Modeling of Physiological Tremor for Active Compensation in Handheld Surgical Robotics [PDF]
IEEE Transactions on Industrial Electronics, 2017 Precision, robustness, dexterity, and intelligence are the design indices for current generation surgical robotics. To augment the required precision and dexterity into normal microsurgical work-flow, handheld robotic instruments are developed to compensate physiological tremor in real time.

Separating in vivo mechanical stimuli for postpneumonectomy compensation: physiological assessment. [PDF]
Journal of Applied Physiology, 2013 Following right pneumonectomy (PNX), the remaining lung expands and its perfusion doubles. Tissue and microvascular mechanical stresses are putative stimuli for initiating compensatory lung growth and remodeling, but their relative contributions to overall compensation remain uncertain.
