Exported oscillator competition: A concept to analyze complex rhythms

Exported oscillator competition: a concept to analyze complex rhythms.

We study the interaction between two independent nonlinear oscillators competing through a neutral excitable element. The first oscillator, completely deterministic, acts as a normal pacemaker sending pulses to the neutral element which fires when it is excited by these pulses. The second oscillator, endowed with some randomness, though unable to make the excitable element to beat, leads to the...

Tracking Rhythms with a Relaxation Oscillator

Deterministic and Stochastic Models Analyze the Robustness of Circadian Rhythms

The Drosophila circadian oscillator shows a robust property to environmental changes, internal variations, and fluctuations, where two interlocked negative feedback loops play a major role for oscillation [1, 2]. The PER-TIM loop is activated by dCLK-CYC and repressed by PER-TIM, whereas the dCLK loop is repressed by dCLK-CYC and activated by PER-TIM. Not only the molecular architecture, but al...

ELISA Analyzer •, a Software to Analyze and Optimize ELISA Data

ELISA data is usually handled in the MS Excel worksheets through different methods and different formulas. Accurate and precise calculations of the data is time consuming and tedious. ELISA Analyzer was developed with a user friendly interface to streamline titration and analysis of the data obtained from ELISA and improve rapid and lucid presentation of the results. The software can also hel...

A Systematic Method to Analyze Transport Networks: Considering Traffic Shifts

Current network modeling practices usually assess the network performance at specified time interval, i.e. every 5 or 10 years time horizon. Furthermore, they are usually based on partially predictable data, which are being generated through various stochastic procedures. In this research, a new quantitative based methodology which combines combinatorial optimization modeling and transportation...
