Summary
This study introduces a dynamic economic model explaining cycles. It reveals how wealth inequality drives economic shocks and influences business cycle oscillations through stochastic fluctuations.
Area of Science:
- Economics
- Economic Modeling
- Dynamical Systems
Background:
- Economic cycles are complex phenomena.

- To explain the mechanisms behind business cycle oscillations.
Main Methods:
- Development of a stochastic dynamic model.
- Analysis of a complex dynamical landscape with multiple stable fixed points.
- Modeling of stochastic fluctuations inducing metastable state switching.
Main Results:
- The model demonstrates a complex economic landscape with distinct income groups.
- Stochastic fluctuations, driven by a few influential agents, cause economic shocks.
- Economic output growth is affected by fluctuations, leading to coherence resonance in business cycles.
Conclusions:

Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

The Swing Equation is a fundamental tool in power system dynamics, especially for analyzing the behavior of generating units like three-phase synchronous generators. This equation emerges from applying Newton's second law to the rotor of a generator, encompassing factors such as inertia, angular acceleration, and the interplay between mechanical and electrical torques.
In a steady-state operation, the mechanical torque (Τm) supplied to the generator is balanced by the electrical torque...

Nonlinear systems often require sophisticated approaches for accurate modeling and analysis, with state-space representation being particularly effective. This method is especially useful for systems where variables and parameters vary with time or operating conditions, such as in a simple pendulum or a translational mechanical system with nonlinear springs.

02:17Microtubule Instability
4.9K
Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated...
