Dissipative Kerr solitons and Cherenkov radiation in optical microresonators with third order dispersion [PDF]

open access: yes, 2017
We present the results of asymptotic and numerical analysis of dissipative Kerr solitons in whispering gallery mode microresonators influenced by higher order dispersive terms leading to the appearance of a dispersive wave (Cherenkov radiation). Combining direct perturbation method with the method of moments we find expressions for the frequency ...

Entropy Measures of Street-Network Dispersion: Analysis of Coastal Cities in Brazil and Britain

open access: yesEntropy, 2013
Geographical location and landforms of various types have strong effects on the developments of many cities and associated street networks. This study presents new results of landform effects, in particular the geometry of shorelines, on the grid street ...

Averaging for the dispersion-managed NLS [PDF]

open access: yesCommun. Contemp. Math. 26, no. 7, Article no. 2350030 (2024), 2022
We establish global-in-time averaging for the $L^2$-critical dispersion-managed nonlinear Schr\"odinger equation in the fast dispersion management regime. In particular, in the case of nonzero average dispersion, we establish averaging with any subcritical data, while in the case of a strictly positive dispersion map, we obtain averaging for data in $L^

Exhaled air dispersion during high-flow nasal cannula therapy versus CPAP via different masks

open access: yesEuropean Respiratory Journal, 2019
Background High-flow nasal cannula (HFNC) is an emerging therapy for respiratory failure but the extent of exhaled air dispersion during treatment is unknown.

Resonant radiation shed by dispersive shock waves [PDF]

open access: yes, 2013
We show that dispersive shock waves resulting from the nonlinearity overbalancing a weak leading-order dispersion can emit resonant radiation owing to higher-order dispersive contributions. We analyze such phenomenon for the defocusing nonlinear Schroedinger equation, giving criteria for calculating the radiated frequency based on the estimate of the ...

The Interplay between Various σ- and π-Hole Interactions of Trigonal Boron and Trigonal Pyramidal Arsenic Triiodides

open access: yesCrystals, 2017
Boron and arsenic triiodides (BI3 and AsI3, respectively) are similar molecules that differ mainly in their geometries. BI3 is a planar trigonal molecule with D3h symmetry, while AsI3 exhibits a trigonal pyramidal shape with C3v symmetry.

Theory of the lattice boltzmann method: dispersion, dissipation, isotropy, galilean invariance, and stability

open access: yesPhysical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 2000
The generalized hydrodynamics (the wave vector dependence of the transport coefficients) of a generalized lattice Boltzmann equation (LBE) is studied in detail.

Amplitude Dispersion Compensation for Damage Detection Using Ultrasonic Guided Waves

open access: yesSensors, 2016
Besides the phase and group velocities, the amplitude of guided wave mode is also frequency dependent. This amplitude dispersion also influences the performance of guided wave methods in nondestructive evaluation (NDE) and structural health monitoring ...
