Unlocking the Secrets of Circadian Rhythms in Drosophila A Breakthrough Study

Understanding Circadian Rhythms in Drosophila

  • Circadian rhythms are 24-hour cycles that regulate biological processes.
  • The study focuses on Period (PER) and Timeless (TIM) proteins in Drosophila.
  • MATLAB’s MATCONT tool was used for bifurcation analysis, while PYOMO and global solvers IPOPT and BARON optimized control mechanisms.

Key Findings of the Study

  • Bifurcation Analysis: Hopf bifurcation points were identified as the cause of oscillatory behavior, making optimization difficult.
  • Control Mechanisms: The study used the tanh activation function to eliminate unwanted oscillations.
  • Optimization Techniques: Multiobjective Nonlinear Model Predictive Control (MNLMPC) ensured maximum beneficial output while reducing inefficiencies.
