Human Cardiovascular System

An analytical study is presented for one-dimensional, pulsatile flow of an incompressible fluid in systems of elastic tubing. Nonlinear terms are retained in the system of describing equations. Three experimental test systems with characteristics similar in some respects to those of the human cardiovascular system are described. These systems were used for experimental verification of the analytical predictions. Comparisons of the analytical predictions and experimental results show that pressures, mass flow rates, and velocities can be predicted with reasonable accuracy for all test conditions employed on the three models.

Asymptotic Reduction

This paper demonstrates an equivalence between rotating magnetized shear flows and a stressed elastic beam. This results from finding the same form of dynamical equations after an asymptotic reduction of the axis-symmetric magnetorotational instability (MRI) under the assumption of almost-critical driving. The analysis considers the MRI dynamics in a non-dissipative near-equilibrium regime. Both the magnetic and elastic systems reduce to a simple one-dimensional wave equation with a non-local nonlinear feedback. Under transformation, the equation comprises a large number of mean-field interacting Duffing oscillators. This system was the first proven example of a strange attractor in a partial differential equation. Finding the same reduced equation in two natural applications suggests the model might result from other applications and could fall into a universal class based on symmetry.

Coherent Transition Radiation

The article discusses the problem of radiation generated during the interaction between the field of relativistic charged particles and metamaterials based on a one-dimensional periodic wire structure. The work includes the experimental study of the reverse coherent transition radiation emitted by these structures in the millimeter wavelength range for two orthogonal directions of radiation polarization. Under the same experimental conditions, authors also compared the intensity of this radiation with the reverse transition radiation from solid conductive targets. The study elucidates the asymmetrical polarization of radiation emitted by a metamaterial wire structure.
