We here experimentally demonstrate that gyration modes of coupled vortices can be resonantly excited primarily by the ac current in a pair of ferromagnetic disks with variable separation. The sole gyration mode clearly splits into higher and lower frequency modes via dipolar interaction, where the main mode splitting is due to a chirality sensitive phase difference in gyrations of the coupled v...

This article studies the controllability of a pair of coupled quantum dots being interrogated by an external electromagnetic field. It is shown that this system is controllable. However, in the limit of large spatial separation between the two dots the dynamical Lie algebra of the problem degenerates to the complex representation of so(4) in su(4). The question of which pure and mixed states fo...

We study synchronization phenomena in a pair of integrateand-fire (IF) oscillators with the width of an action potential. They have slightly different periodic firings each other. Such non-identical IF oscillators typically interact with each other via excitatory or inhibitory synaptic stimuli. A return map analysis gives us a systematic analysis of stabilities of the 1 : 1 phase locking states...

State-space formulas are derived for the minimumentropy H∞ controller when the plant and controller are constrained to be block-lower-triangular. Such a controller exists if and only if: the corresponding unstructured problem has a solution, a certain pair of coupled algebraic Riccati equations admits a mutually stabilizing fixed point, and a pair of spectral radius conditions is met. The contr...

Electron spin echo envelope modulation (ESEEM) has been observed for the first time from a coupled heterospin pair of electron and nucleus in liquid solution. Previously, modulation effects in spin-echo experiments have only been described in liquid solutions for a coupled pair of homonuclear spins in nuclear magnetic resonance or a pair of resonant electron spins in electron paramagnetic reson...

Suppose X is a partially ordered real Banach space such that there is a 2−norm on X. The purpose of this paper is to prove coupled coincidence and coupled common fixed point theorems for mappings from X ×X to X.

Theoretical description of the pair production cross sections are discussed in several papers [1, 2, 3, 4, 5]. The tabulated data results that were used are calculated by H. Hubbell, H. A. Gimm, I. Overbo in JPCRD 9(4) pp. 1023-1147 (1980). The pair production cross sections are based on BetheHeithler bremsstrahlung cross sections since these two physical processes have similarities. If we take...

The transmission line model for the single and coupled microstrip line components implemented in APLAC are presented. A detailed description of the algorithm used to calculate the characteristic impedance and the effective permittivity is given for the single microstrip, the symmetrical and asymmetrical pair of coupled microstrip lines, and the n symmetrical coupled microstrip lines. The effect...

With the aid of spectral gradient method Fuchssteiner, compatible pair Hamiltonian operators for coupled NLS hierarchy is rediscovered. This result enables us to construct a hierarchy, which contains vector generalization Fokas-Lenells system. The system shown be bi-Hamiltonian and possess Lax pair.

This paper presents a study of narrow bandwidth the bandpass filter with cross-coupled line structure. structure was designed to have good selectivity transmission zeros and simple design. Since has cross shape, cross-coupling between resonators consequently occurs. interferes passband filter. Optimization in size coupled lines done minimize interference. Rogers RT/duroid 5880 used as substrate...
