We present the MABSys package which gathers, as much as possible, some functions to carry out the modeling of biochemical reaction networks, their qualitative analysis and the exact simplification of systems of ordinary differential equations. Then we discuss Tyson’s negative feedback oscillator model and the parameters values for which this system oscillates.

We review the experimental constraints on additional macroscopic Yukawa forces for interaction ranges below 1 cm, and summarize several theoretical predictions of new forces in this region. An experiment using 1 kHz mechanical oscillators as test masses should be sensitive to much of the parameter space covered by the predictions.

AIM To enhance the clinical utility of electrogastrography (EGG), which has been recorded since 1922, but is clinically unutilized. METHODS An innovative method to salvage the promise of EGG is proposed by introducing a preliminary procedure, while maintaining the electrodes, standardized equipment, and signal processing utilized in the well-established EGG testing of today. The proposed enha...

We report results from measurements for differential and integral cross sections of the unresolved (1)B(1u) and (3)E(2g) electronic states and the (1)E(1u) electronic state in benzene. The energy range of this work was 10-200 eV, while the angular range of the differential cross sections was ∼3°-130°. To the best of our knowledge there are no other corresponding theoretical or experimental data...

The Brownian oscillator model for the coupling of solvent motions to a solute’s electronic transitions is applied to the calculation of absorption, relaxed fluorescence, and unrelaxed total emission (Raman and fluorescence) band shapes of a diatomic molecule in solution. The band shapes and the ratios of sharp scattering to broad fluorescence are explored as a function of the laser detuning fro...

A unidirectional coupling scheme is investigated in double scroll type chaotic oscillators that reveal interesting multiscroll dynamics. Instead of using self-oscillatory systems, in this scheme, double scroll chaos from one oscillator is forced into another similar oscillator in a resting state. This coupling scheme is explored in the Chua oscillator, a modified Chua oscillator and the Lorenz ...

Introduction: Oscillation based test (OBT) method [1] has been applied to testing different types of analogue circuits [2-5]. In this approach, the circuit is transformed into an oscillator during the test mode and the frequency of oscillation is measured and compared to the reference value obtained on a known-good circuit operating in the same conditions. Circuit modification for the purpose o...

We have developed a variational perturbation theory based on the LiouvilleNeumann equation, which enables one to systematically compute the perturbative correction terms to the variationally determined wave functions of the time-dependent systems. We then apply the method to the time-independent anharmonic oscillator, and show that the results agree with those of other variational perturbation ...
