Homeostatic adaptive networks
… view of homeostasis and develop a theory of homeostatic adaptive systems. We study homeostatic adaptive networks by looking at specific examples of homeo-static systems: the Homeostat, homeostatic plasticity in neural networks, and homeostatic regulation of the environment by the biota. …

Neural Mechanisms of Homeostatic Need and Reward
… programs towards restoration of these needs. The homeostatic control of these need states further enables animals to maintain their survival strength and adapt to the environment. In contrast,dysregulation of these need-sensing neurons causes diseases such as obesity and sleep disorders,both of …

Homeostatic Elastic States and the Stability of Elastic Arteries
… a rigorous analysis of i) the mechanics of the homeostatic states of uniform circumferential stress and uniform stretch in an N-layer cylindrical artery subject to circumferential prestress, axial tethering force and the pressure of blood and ii) the local mechanical stability by imperfection …

Breaking Away: The Role of Homeostatic Drive in Perpetuating Depression
… psychological activity, neurochemicals act as homeostatic regulators. This study proposes that these components are part of a regulatory system that is capable of supporting multiple homeostatic regimes that, in turn, give rise to self-sustaining psychological behaviors. This project …

Regulation of macrophage subsets in homeostatic and inflammatory mucosal environments
The interaction between epithelial cells and macrophages is integral to mucosal immune fate: determining the decision between tolerance and immune activation/inflammation. Endotoxin tolerisation (ET) is a circumstance where cells go through a hypo-responsive state, unable to respond to further …

Homeostatic-inspired controller algorithm for a hybrid-driven autonomous underwater glider
… facing these constraints. A robust and reliable homeostatic-inspired controller system has been designed for this purpose. The controller is able to adapt efficiently to the dynamically changing conditions and is able to compensate the disturbance from water currents. The controller algorithm has …

Homeostatic mechanics framework for modelling interactions of cells with the microenvironment
… and their subcellular components with the novel homeostatic mechanics framework that recognises the non-thermal fluctuating response of living cells. We show that similar to nematic ordering in liquid crystals, orientational ordering of cells on micropatterns is driven, rather …

Integration of Homeostatic and Hedonic Brain Centers in the Regulation of Feeding Behaviors
… of high-fat food is potentiated by aberrant homeostatic feeding behavior (i.e. titration of caloric intake), which typically associates with hypothalamic brain nuclei, specifically the paraventricular nucleus of the hypothalamus (PVN) which controls food intake to maintain body weight. …

Activity-dependent regulation of GIRK and Kv7 channels in homeostatic plasticity and epilepsy
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2022-11-15 without embargo terms

Stem and Progenitor Cells in Homeostatic Maintenance and Perturbation of the Pulmonary Epithelium
… tissue-sharing counterparts do not alter from homeostatic behaviour. These findings were confirmed with single cell RNA sequencing, which also indicates reduced signalling between SecC-derived PIK3CAH1047R mutant cells and tissue-sharing basal cells. I also performed a detailed analysis …

Speech and gesture understanding in a homeostatic control framework for a robotic chandelier
We describe a home lighting robot that uses directional spotlights to create complex lighting scenes. The robot senses its visual environment using a panoramic camera and attempts to maintain its target goal state by adjusting the positions and intensities of its lights. Users can communicate …

THE ROLE OF SELECTIVE MRNA DEADENYLATION IN THE HOMEOSTATIC CONTROL OF INNATE IMMUNE SIGNALING
The homeostatic control of innate immunity is essential to health as dysregulation can lead to poor outcomes during infection or inflammatory conditions including autoimmunity. Interferon signaling is the specific antiviral arm of the innate immune system responsible for inducing interferons and …

Homeostatic mechanics for a synthetic cell: predictions on substrate anisotropies and cell-cell interactions
… and theoretical investigations by extending the Homeostatic Ensemble framework to elucidate the elusive physics and key parameters guiding cell response to a diverse set of cues. We first proceed to extend the framework to a non-equilibrium setting to capture the evolution rates governing cell …

Motor neuron output in the crustacean cardiac ganglion is organized and maintained by homeostatic conductance relationships
Generating appropriate and functional neuronal output is a matter of fundamental importance to nervous systems across species and phyla. Potential perturbations to a neurons intrinsic excitability alone include Hebbian style plasticity, ion channel turnover and neuromodulation. With these dynamic …

Novel roles of striatal enriched protein phosphatase (STEP) in neuronal intrinsic properties and homeostatic synaptic plasticity
… it was unknown whether STEP contributes to homeostatic synaptic plasticity, a compensatory mechanism by which neurons adjust their synaptic strength within a normal range in response to chronic activity challenge. In addition, whether STEP regulates somatic intrinsic properties of …

Autophagy maintains the homeostatic environment in the male reproductive organs playing a key role in fertility
Autophagy is an evolutionarily conserved recycling process that plays a crucial role in maintaining cellular homeostasis. It has been reported that autophagy is closely involved in the physiological process of spermatogenesis and the regulation of sperm survival. However, the role of autophagy …

THE EFFECTS OF GASTRIC AND HOMEOSTATIC AUTONOMIC AFFERENT REFLEXES ON CARDIAC AUTONOMIC EFFERENT ACTIVITY IN HEALTHY HUMAN VOLUNTEERS
The effects of gastric autonomic afferent reflexes on cardiovascular autonomic efferent activity are regarded as a direct neural effect of the activation of gastric receptors which send afferent inputs to the central nervous system (CNS) to cause various cardiovascular changes (Van Orshoven et al., …
