On the derivation of the wave kinetic equation for NLS [PDF]
Forum of Mathematics, Pi, 2019 A fundamental question in wave turbulence theory is to understand how the wave kinetic equation describes the long-time dynamics of its associated nonlinear dispersive equation.

Scattering for the non-radial inhomogeneous NLS [PDF]
Mathematical Research Letters, 2019 We extend the result of Farah and Guzman on scattering for the $3d$ cubic inhomogeneous NLS to the non-radial setting. The key new ingredient is a construction of scattering solutions corresponding to initial data living far from the origin.

Proceedings of the fifth conference on Applied natural language processing Descriptions of system demonstrations and videos -, 1997 We will be demonstrating a toolkit for developing natural language-based applications and two applications. The goals of this toolkit are to reduce development time and cost for natural language based applications by reducing the amount of linguistic and programming work needed.

Scattering of radial data in the focusing NLS and generalized Hartree equations [PDF]
Discrete and Continuous Dynamical Systems. Series A, 2019 We consider the focusing nonlinear Schrodinger equation $i u_t + \Delta u + |u|^{p-1}u=0$, $p>1,$ and the generalized Hartree equation $iv_t + \Delta v + (|x|^{-(N-\gamma)}\ast |v|^p)|v|^{p-2}u=0$, $p\geq2 ...

Study on the effect of color space in deep multitask learning neural networks for road segmentation [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information SciencesPrecise road segmentation is an essential part of many applications related to road information extraction from remote sensing data. The effect of color space on road detection has rarely been studied. In this paper, the effects of different color spaces

The finite gap method and the analytic description of the exact rogue wave recurrence in the periodic NLS Cauchy problem. 1 [PDF]
Nonlinearity, 2017 The focusing nonlinear Schrödinger (NLS) equation is the simplest universal model describing the modulation instability (MI) of quasi monochromatic waves in weakly nonlinear media; MI is considered the main physical mechanism for the appearance of rogue (
