An oscillatory network of columnar architecture located in 3D spatial lattice was recently designed by the authors as oscillatory model of the brain visual cortex. Single network oscillator is a relaxational neural oscillator with internal dynamics tunable by visual image characteristics - local brightness and elementary bar orientation. It is able to demonstrate either activity state (stable u...

The Lorentz oscillator model is well-known for its effectiveness to describe the farinfrared optical properties of polar materials. The oscillator strength and damping factor in this model are usually obtained by fitting to experimental data. In this work, a method based on first-principles simulations is developed to parameterize the Lorentz oscillator model without any fitting parameters. The...

Line intensities and oscillator strengths for the controversial 3C and 3D astrophysically relevant lines in neonlike Fe(16+) ions are calculated. A large-scale configuration-interaction calculation of oscillator strengths is performed with the inclusion of higher-order electron-correlation effects, suggesting that these contributions cannot explain existing discrepancies between theory and expe...

Relativistic configuration interaction calculations have been done for Mo VI 4p 4d J = 5/2 and nf F5/2 (n=4-6) wave functions. Level energies and E1 oscillator strengths for transitions between these states and the nd D (n=4-6) states have been obtained. The calculated LS compositions of all 11 levels of 4p 4d J = 5/2 have been found to be in good agreement with other designations. While most c...

Abstract The interrelationship between the non-Markovian stochastic Schrödinger equations and the corresponding non-Markovian master equations is investigated in the finite temperature regimes. We show that the general finite temperature non-Markovian trajectories can be used to derive the corresponding non-Markovian master equations. A simple, yet important solvable example is the well-known d...

A coupled-oscillators-model-based method for measuring speech rhythm is presented. This model explains crosslinguistic differences in rhythm as deriving from varying degrees of coupling strength between a syllable oscillator and a phrase stress oscillator. The method was applied to three texts read aloud in French, in Brazilian and European Portuguese by seven speakers. The results reproduce th...

The harmonic oscillator is one of the most widely used model systems in physics: an indispensable theoretical tool in a variety of fields. It is well known that an otherwise linear oscillator can attain novel and nonlinear features through interaction with another dynamical system. We investigate such an interacting system: a superconducting LC-circuit dispersively coupled to a superconducting ...

Starting from the boundary CFT definition for the D-branes in vacuum string field theory (VSFT) given in hep-th/0105168, we derive the oscillator expression for the D24brane solution in the VSFT on D25-brane. We show that the state takes the form of a squeezed state, similar to the one found directly in terms of the oscillators and reported in hep-th/0102112. Both the solutions are actually one...

We study perturbation with period T(p) of one of two model Belousov-Zhabotinsky chemical oscillators diffusively coupled through an inhibitory species. We find a variety of resonance regimes, characterized as N1:N2:n , where N1 (N2) and n are the numbers of spikes of the perturbed (unperturbed) oscillator and the external perturbation, respectively, per global period T(G). The resonance mode is...

Vertical excitation energies as well as related absolute photoabsorption oscillator strength data are very scarce in the literature for methane. In this study, we have characterized the three existing series of low-lying Rydberg states of CH4 by computing coupled cluster linear response (CCLR) vertical excitation energies together with oscillator strengths in the molecular-adapted quantum defec...
