A number of physiological processes in living organisms involve the selective "catch and release" of biomolecules. Inspired by these biological processes, we use computational modeling to design synthetic systems that can controllably catch, transport, and release specific molecules within the surrounding solution, and, thus, could be harnessed for effective separation processes within microflu...

The vector potential is A=(μo/4π)qv/r, from which B=∇×A. Upon any acceleration of the charge, one finds a long range electric field, E=− ∂A/∂t. The range of this 1/r field far exceeds that from a charge, which goes as 1/r2 or a dipole which goes as 1/r3. This E field differs from Hertz’ solution for an oscillating charge. Hertz’ finding of TEM waves from an oscillating charge is flawed by the i...

We develop a theory of intracavity four-wave interaction. As a result of such interaction, two photons of the pump fields produce a pair of photons of the cavity's signal mode with the same frequency. In addition to taking into account the parametric process of photon transformation and dissipation processes, we allow for the effects of phase self-modulation of the signal mode and its cross mod...

This paper presents a spectral analysis of the response of a fluid containing bubbles to the motions of a wall oscillating normal to itself. First, a Fourier analysis of the Rayleigh-Plesset equation is used to obtain an approximate solution for the nonlinear effects in the oscillation of a single bubble in an infinite fluid. This is used in the approximate solution of the oscillating wall prob...

A viscometer for bedside blood measurements was developed, consisting of an oscillating resonator probe mounted directly into a disposable vacutainer tube for blood withdrawal. It was tested in vitro on blood samples with variable hematocrits (20-60%), increasing fibrinogen concentrations (0-20 g/l), increasing concentrations of an admixed radiographic contrast medium and erythrocyte suspension...

This paper presents simplified hydrodynamics model for a biomimetic robot fish based on quantitative morphological and kinematic parameters of crangiform fish. The motion of four Pangasius sanitwongsei with different length and swimming speed were recorded by the digital particle image velocimetry (DPIV) and image processing methods and optimal coefficients of the motion equations and appropria...
