Non oscillating solutions of analytic gradient vector fields [PDF]

Annales de l'Institut Fourier, 1998
Let γ be an integral solution of an analytic real vector field ξ defined in a neighbordhood of 0∈ℝ 3 . Suppose that γ has a single limit point, ω(γ)={0}. We say that γ is non oscillating if, for any analytic surface H, either γ is contained in H or γ cuts H only finitely many times.

Mechanical Amplification by Non-Oscillating Saccular Hair Cell Bundles [PDF]

Biophysical Journal, 2014
Hair cells from the inner ear are the mechano-electrical transducers for biological sound detection. Under in vitro conditions, hair bundles from bullfrog sacculus can exhibit spontaneous oscillations, which suggest the existence of an active process that might underlie its exquisite sensitivity to mechanical stimulations.

Explicit criteria for the oscillation of second-order differential equations with several sub-linear neutral coefficients

Advances in Difference Equations, 2020
In this work, we present sufficient conditions for oscillation of all solutions of a second-order functional differential equation. We consider two special cases when γ > β $\gamma >\beta $ and γ < β $\gamma

Non-Stationary Power System Forced Oscillation Analysis Using Synchrosqueezing Transform [PDF]

IEEE Transactions on Power Systems, 2020
Non-stationary forced oscillations (FOs) have been observed in power system operations. However, most detection methods assume that the frequency of FOs is stationary.In this paper, we present a methodology for the analysis of non-stationary FOs. Firstly,

Oscillation of a second order half-linear difference equation and the discrete Hardy inequality

Electronic Journal of Qualitative Theory of Differential Equations, 2017
In local terms on finite and infinite intervals we obtain necessary and sufficient conditions for the conjugacy and disconjugacy of the following second order half-linear difference equation \begin{equation*} \Delta(\rho_i|\Delta y_i|^{p-2}\Delta y_i ...

Optical Parametric Oscillation with Ultra-Low Power Threshold in a Dimer of Active-Passive Cavities

Crystals, 2021
Optical parametric oscillation can convert the input laser into a couple of coherent optical output with signal and idler frequencies. It is an important method for the realization of the broadband middle infrared tunable lasers.

Neutrino mass spectrum and neutrinoless double beta decay [PDF]

, 2000
The relations between the effective Majorana mass of the electron neutrino, $m_{ee}$, responsible for neutrinoless double beta decay, and the neutrino oscillation parameters are considered.

Linking the flow-induced tremor model to the seismological observation: application to the deep harmonic tremor at Hakone volcano, Japan

Earth, Planets and Space, 2023
Decades ago, Julian (J Volcanol Geotherm Res 101:19–26, 1994. https://doi.org/10.1029/93JB03129 ) proposed the lumped parameter model of non-linear excitation of an elastic channel vibration by fluid flow as a mechanism of volcanic harmonic tremor. Since
