Double-mode Cepheid behaviour may arise either from non-resonant or resonant mode interaction. Inclusion of turbulent convection into pulsation codes by Kollath et al. led to stable double-mode F+10 Cepheid pulsation [1]. However, our recent computations indicate that these models resulted from an...
Dependence of the modulus b 1 on the wave number κ near the eigen frequency k 12. Waveguide parameters: a= 1.1, d= 1.3 Full size image If the size of barrier decreases, then the resonant values of k decrease slightly also. The dependence of the conditional number cond A = |...
A comparative study of the optimal on-resonance vs. off-resonance sequence was performed to evaluate each sequence in coronary vein imaging. MATERIALS AND METHODS The parameters including repetition, flip angle and order of a binomial on-resonant MT sequence were optimized by numerical simulation of...
In these studies, a nonresonant loop was used to induce currents into a metasurface that was operated as a passive inductively powered resonator. However, as we show in this study, the strategy of using a resonant metasurface reduces the impact of the loop on the global performance of the ...
An in-vivo study of resonant photoacoustic spectroscopy (PAS) was performed for non-invasive blood glucose monitoring. PAS provides robustness against the background of the optical absorption. In the in-vivo study, oral glucose tolerance tests (OGTTs) were performed with three healthy people to i...
We summarize improvements to the performance of oscillators based on double-barrier resonant-tunneling diodes and their relationship to developments in three material systems. Higher frequencies, and more recently higher output powers, have resulted from these materials developments, so that today waveguide...

We report on our observation of a structure in the valley region of the current-voltage characteristic of a double-barrier resonant-tunneling structure. We attribute this feature to the LO-phonon-emission-assisted tunneling of electrons ... VJ Goldman,DC Tsui,JE Cunningham - 《Physical Review B...
resonant couplingsplicing lossThe design of a low-bending loss few-mode optical fibre is proposed. Low-bending loss for the fundamental mode is achieved by increasing the index contrast between the core and the cladding, and a microstructured mode filtering region is applied to filter out the ...
