Updating Homeostasis

چکیده
10 years ago, a group of us put on an international meeting at the NIH entitled “The Energetic and Dynamic Basis of Health and Aging” [3]. The centerpiece of our conference was the reification of the term homeodynamics [4]. This word was proposed and elaborated by Dr. Gene Yates of UCLA who was a leader of our conference. Homeodynamics extends homeostasis into a more inclusive term. It is evident that there is no stasis in life. All of life is dynamic. 98% of a body’s atoms are replaced each year. The Krebs cycle turns over 2.66x10^21 times per minute. The half-life of an intestinal cell is measured in days. Stasis is nowhere to be found. Life is a verb rather than a noun.

New Threshold Updating Mechanism to Stabilize Activity of Hebbian Neuron in a Dynamic Stochastic ‘Multiple Synaptic’ Network, similar to Homeostatic Synaptic Plasticity Process
Unconstrained growth of synaptic activity and lack of references to synaptic depression in Hebb‟s postulate have diminished its value as a learning algorithm. The existing synaptic scaling mechanisms such as weight normalization, threshold updating, and spike time dependent plasticity have greatly contributed to address these issues in Hebb‟s postulate. However, all these mechanisms are based o...
متن کاملEvaluation of Updating Methods in Building Blocks Dataset
With the increasing use of spatial data in daily life, the production of this data from diverse information sources with different precision and scales has grown widely. Generating new data requires a great deal of time and money. Therefore, one solution is to reduce costs is to update the old data at different scales using new data (produced on a similar scale). One approach to updating data i...
متن کاملDAMAGE IDENTIFICATION OF TRUSSES BY FINITE ELEMENT MODEL UPDATING USING AN ENHANCED LEVENBERG-MARQUARDT ALGORITHM
This paper presents an efficient method for updating the structural finite element model. Model updating is performed through minimizing the difference of recorded acceleration of real damaged structure and hypothetical damaged structure, by updating physical parameters in each phase using iterative process of Levenberg-Marquardt algorithm. This algorithm is based on sensitivity analysis and pr...
