The complex natural resonances (CNR) for lossless dielectric spheres in a lossless dielectric medium are investigated. Significant differences between the external and internal resonances are presented. The external resonances are related to the external creeping waves and the internal resonances to the internally reflected waves. The internal resonances are more important in practice because o...
In this paper we give survey of the results concerning the solvability of certain quasilinear boundary value problems which contain the p-Laplacian as a main part. Special attention is paid to the resonance problems which lead naturally to the study of spectral properties of nonlinear operators. Besides statements of principal results in the historical context we also mention some open problems...
*Correspondence: [email protected] Department of Mathematics, China University of Mining and Technology, Xuzhou, 221008, People’s Republic of China Abstract In this paper, by using the coincidence degree theory, we study the existence of solutions for a coupled system of fractional differential equations at resonance. A new result on the existence of solutions for a fractional boundary value probl...
We prove that the Frobenius–Perron operator of the cusp map F : [−1, 1] → [−1, 1], F (x) = 1 − 2 √ |x| (which is an approximation of the Poincaré section of the Lorenz attractor) has no analytic eigenfunctions corresponding to eigenvalues different from 0 and 1. We also prove that the spectrum of the Frobenius–Perron operator in the space of real-analytic functions on [0, 1] as well as in the s...
We implement several non-binary logic systems using the spin dynamics of nuclear spins in nuclear magnetic resonance (NMR). The NMR system is a suitable test system because of its high degree of experimental control; findings from NMR implementations are relevant for other computational platforms exploiting particles with spin, such as electrons or photons. While we do not expect the NMR system...
Using a sample of 58× 106 J/ψ events collected with the BESII detector, radiative decays J/ψ → γγV , where V = ρ or φ, are studied. A resonance around 1420 MeV/c2 (X(1424)) is observed in the γρ mass spectrum. Its mass and width are measured to be 1424 ± 10 (stat) ± 11 (sys) MeV/c2 and 101.0 ± 8.8 ± 8.8 MeV/c2, respectively, and its branching ratio B(J/ψ → γX(1424) → γγρ) is determined to be (1...
This study explores the relationship between identification, degree of nasality and vowel quality in oral, nasal and nasalized vowels in Brazilian Portuguese. Despite common belief that the language possesses contrastive nasal vowels, literature examination shows that nasal vowels may be followed by a nasal resonance, while nasalized vowels must be followed by a nasal consonant. It is argued th...
Using large Nc counting rule, it is argued that tetra-quark resonances do not exist. Also it is pointed out that there exists the violation of exchange degeneracy in the exotic KN scattering channel. It implies either the failure of resonance saturation assumption or it suggests the existence of exotic baryon resonances in such a channel.
The π+π− balance function in rapidity is computed in a thermal model with resonances. It is found that the correlations from the neutral-resonance decays are important, yielding about a half of the total contribution, which in general consist of resonance and non-resonance parts. The model yields the pionic balance function a few per cent wider that what follows from the recent data for the Au+...
