Dynamics Finite Buffer Queue Conditioned Amount of Loss
2015/7/6
This paper is concerned with computing large deviations asymptotics for the loss process in a stylized queueing model that is fed by a Brownian input process. In addition, the dynamics of the queue, c...
On the Dynamics of Semimartingales with Two Reflecting Barriers
Dynamics Semimartingales Reflecting Barriers
2015/7/6
We consider a semimartingale X which is reflected at an upper barrier T and a lower barrier S, where S and T are also semimartingales such that T is bounded away from S. First, we present an explicit ...
Elevating Repositioning Costs:Strategy Dynamics and Competitive Interactions in Grand Strategy
Organizational Change and Adaptation Strategy Cost
2015/4/29
This paper proposes an approach for modeling strategic interactions that incorporates the costs to firms of changing their strategies. The costs associated with strategy modifications, which we term "...
The Dynamics of Firm Lobbying
Lobbying Political Economy H-1B Business Ventures Policy Government Legislation Immigration
2015/4/24
We study the determinants of the dynamics of firm lobbying behavior using a panel data set covering 1998–2006. Our data exhibit three striking facts: (i) few firms lobby, (ii) lobbying status is stron...
Focusing Revisited: an MN-dynamics Approach
Nonlinear Schr odinger equation the dispersion system focusing on NLS equation
2014/12/29
The nonlinear Schr¨odinger (NLS) equation is a ubiquitous example of an envelope wave equation for conservative, dispersive systems. We revisit here the problem of self-similar focusing of waves in th...

2014/12/29
The dynamics of linear and nonlinear excitations in a Bose gas in the Tonks-Girardeau regime with longitudinal confinement are studied within a mean-field theory of quintic nonlinearity. A reductive p...
Breather statics and dynamics in Klein-Gordon chains with a bend
Nonlinear model the model of the power of the bending Angle scattering
2014/12/29
In this paper, we examine a nonlinear model with an impurity emulating a bend. We justify the geometric interpretation of the model and connect it with earlier work on models including geometric effec...
Nonlinear lattice dynamics of Bose–Einstein condensates
Non-metallic solid nonlinear multi degree of freedom nonlinear Hamiltonian system the lattice dynamics system
2014/12/29
The Fermi–Pasta–Ulam (FPU) model, which was proposed 50 years ago to examine thermalization in nonmetallic solids and develop “experimental” techniques for studying nonlinear problems, continues...

Condensate similar soliton parabolic magnetic trap periodic optical lattice space
2014/12/29
Motivated by the recent experimental achievements in the work with Bose-Einstein condensates (BECs), we consider bright matter-wave solitons, in the presence of a parabolic magnetic trap and a spatial...

2014/12/25
We study the existence and stability of bright, dark, and gap matter-wave solitons in optical superlattices. Then, using these properties, we show that (time-dependent) “dynamical superlattices” can b...

2014/12/25
We introduce an inhomogeneously nonlinear Schrödinger lattice, featuring a defocusing segment, a focusing segment and a transitional interface between the two. We illustrate that such inhomogeneo...

We study soliton dynamics in a system of two linearly coupled discrete nonlinear Schrödinger equations, which describe the dynamics of a two-component Bose gas, coupled by an electromagnetic fiel...
