Electron-Inertia Effects On Driven Magnetic Field Reconnection, N. Al-Salti, B. K. Shivamoggi Jan 2003

Electron-Inertia Effects On Driven Magnetic Field Reconnection, N. Al-Salti, B. K. Shivamoggi

Faculty Bibliography 2000s

Electron-inertia effects on the magnetic field reconnection induced by perturbing the boundaries of a slab of plasma with a magnetic neutral surface inside are considered. Energetics of the tearing mode dynamics with electron inertia which controls the linearized collisionless magnetohydrodynamics (MHD) are considered with a view to clarify the role of the plasma pressure in this process. Cases with the boundaries perturbed at rates slow or fast compared with the hydromagnetic evolution rate are considered separately. When the boundaries are perturbed at a rate slow compared with the hydromagnetic evolution rate and fast compared with the resistive diffusion rate, the …

Coherence Properties Near Interfaces Of Random Media, A. Apostol, A. Dogariu Jan 2003

Coherence Properties Near Interfaces Of Random Media, A. Apostol, A. Dogariu

Faculty Bibliography 2000s

The spatial coherence theory of optical fields radiated by statistically homogeneous, infinite, planar sources does not account for detailed surface characteristics. However, coherence properties change with the angular distribution of the intensity radiated from such a source, which, in turn, depends on the physical properties of the sample. We show that second-order correlations of the optical field measured at several wavelengths away from the surface of a highly inhomogeneous medium relate to the statistical characteristics of the interface.

Financial Factors And Investment In Belgium, France, Germany, And The United Kingdom: A Comparison Using Company Panel Data, Stephen Bond, Julie Ann Elston, Jacques Mairesse, Benoît Mulkay Jan 2003

Financial Factors And Investment In Belgium, France, Germany, And The United Kingdom: A Comparison Using Company Panel Data, Stephen Bond, Julie Ann Elston, Jacques Mairesse, Benoît Mulkay

Faculty Bibliography 2000s

We construct company panel data sets for manufacturing firms in Belgium, France, Germany, and the United Kingdom, covering the period 1978-1989. These data sets are used to estimate empirical investment equations, and to investigate the role played by financial factors in each country. A robust finding is that cash flow and profits terms appear to be both statistically and quantitatively more significant in the United Kingdom than in the three continental European countries. This is consistent with the suggestion that financial constraints on investment may be relatively severe in the more market-oriented U.K. financial system.

Incoherent White Light Solitons In Logarithmically Saturable Noninstantaneous Nonlinear Media, H. Buljan, A. Šiber, M. Soljacic, T. Schwartz, M. Segev, Demetrios N. Christodoulides Jan 2003

Incoherent White Light Solitons In Logarithmically Saturable Noninstantaneous Nonlinear Media, H. Buljan, A. Šiber, M. Soljacic, T. Schwartz, M. Segev, Demetrios N. Christodoulides

Faculty Bibliography 2000s

We analytically demonstrate the existence of white light solitons in logarithmically saturable noninstantaneous nonlinear media. This incoherent soliton has elliptic Gaussian intensity profile, and elliptic Gaussian spatial correlation statistics. The existence curve of the soliton connects the strength of the nonlinearity, the spatial correlation distance as a function of frequency, and the characteristic width of the soliton. For this soliton to exist, the spatial correlation distance must be smaller for larger temporal frequency constituents of the beam.

Observation Of Multiple Soliton Generation Mediated By Amplification Of Asymmetries, Silvia Carrasco, Sergey Polyakov, Hongki Kim, Ladislav Jankovic, George I. Stegeman, Juan P. Torres, Lluis Torner, Mordechai Katz, David Eger Jan 2003

Observation Of Multiple Soliton Generation Mediated By Amplification Of Asymmetries, Silvia Carrasco, Sergey Polyakov, Hongki Kim, Ladislav Jankovic, George I. Stegeman, Juan P. Torres, Lluis Torner, Mordechai Katz, David Eger

Faculty Bibliography 2000s

We report the experimental observation of the formation of multiple optical quadratic solitons in a process mediated by the amplification of minute asymmetries in the diffraction properties of the input light. Experiments were conducted in phase-matched second-harmonic generation in a bulk crystal of periodically poled potassium titanyl phosphate pumped at 1064 nm. The different mechanisms that influence the process were investigated numerically, and the pulsed nature of the pump light was found to play a key role in the observed light distributions.

Discrete Ginzburg-Landau Solitons, Nikolaos K. Efremidis, Demetrios N. Christodoulides Jan 2003

Discrete Ginzburg-Landau Solitons, Nikolaos K. Efremidis, Demetrios N. Christodoulides

Faculty Bibliography 2000s

We demonstrate that discrete solitons are possible in Ginzburg-Landau lattices. As a result of discreteness, we find that this system exhibits a host of features that have no counterpart whatsoever in either the continuous limit or in other conservative discrete models.

Lattice Solitons In Bose-Einstein Condensates, Nikolaos K. Efremidis, Demetrios N. Christodoulides Jan 2003

Lattice Solitons In Bose-Einstein Condensates, Nikolaos K. Efremidis, Demetrios N. Christodoulides

Faculty Bibliography 2000s

We systematically study the properties of lattice solitons in Bose-Einstein condensates with either attractive or repulsive atom interactions. This is done, by exactly solving the mean-field Gross-Pitaevskii equation in the presence of a periodic potential. We find new families of lattice soliton solutions that are characterized by the position of the energy eigenvalue within the associated band structure. These include lattice solitons in condensates with either attractive or repulsive atom interactions that exist in finite or semi-infinite gaps, as well as nonlinear modes that exhibit atomic population cutoffs.

A General Paradigm To Model Reaction-Based Biogeochemical Processes In Batch Systems, Yilin Fang, Gour-Tsyh Yeh, William D. Burgos Jan 2003

A General Paradigm To Model Reaction-Based Biogeochemical Processes In Batch Systems, Yilin Fang, Gour-Tsyh Yeh, William D. Burgos

Faculty Bibliography 2000s

[1] This paper presents the development and illustration of a numerical model of reaction-based geochemical and biochemical processes with mixed equilibrium and kinetic reactions. The objective is to provide a general paradigm for modeling reactive chemicals in batch systems, with expectations that it is applicable to reactive chemical transport problems. The unique aspects of the paradigm are to simultaneously (1) facilitate the segregation (isolation) of linearly independent kinetic reactions and thus enable the formulation and parameterization of individual rates one reaction by one reaction when linearly dependent kinetic reactions are absent, (2) enable the inclusion of virtually any type of …

Simulations Of Liquid-Crystal Fabry-Perot Etalons By An Improved 4x4 Matrix Method, Yuhua Huang, Thomas X. Wu, Shin-Tson Wu Jan 2003

Simulations Of Liquid-Crystal Fabry-Perot Etalons By An Improved 4x4 Matrix Method, Yuhua Huang, Thomas X. Wu, Shin-Tson Wu

Faculty Bibliography 2000s

The optical performances of a liquid crystal (LC) Fabry-Perot (FP) etalon in various configurations were simulated by a faster 4 x 4 matrix method. Results show that the FP with a 90degrees twisted nematic LC is polarization. insensitive if the applied voltage exceeds similar to3X of the Freedericksz transition threshold. This method can well depict the transmission spectra of the FP cavity and, therefore, is useful for optimizing the FP tunable filters for telecommunications.

Discrete Vector Solitons In Two-Dimensional Nonlinear Waveguide Arrays: Solutions, Stability, And Dynamics, J. Hudock, P. G. Kevrekidis, B. A. Malomed, Demetrios N. Christodoulides Jan 2003

Discrete Vector Solitons In Two-Dimensional Nonlinear Waveguide Arrays: Solutions, Stability, And Dynamics, J. Hudock, P. G. Kevrekidis, B. A. Malomed, Demetrios N. Christodoulides

Faculty Bibliography 2000s

We identify and investigate bimodal (vector) solitons in models of square-lattice arrays of nonlinear optical waveguides. These vector self-localized states are, in fact, self-induced channels in a nonlinear photonic-crystal matrix. Such two-dimensional discrete vector solitons are possible in waveguide arrays in which each element carries two light beams that are either orthogonally polarized or have different carrier wavelengths. Estimates of the physical parameters necessary to support such soliton solutions in waveguide arrays are given. Using Newton relaxation methods, we obtain stationary vector-soliton solutions, and examine their stability through the computation of linearized eigenvalues for small perturbations. Our results may also …

Minimum Lagrange Multiplier Unit Root Test With Two Structural Breaks, Junsoo Lee, Mark C. Strazicich Jan 2003

Minimum Lagrange Multiplier Unit Root Test With Two Structural Breaks, Junsoo Lee, Mark C. Strazicich

Faculty Bibliography 2000s

The endogenous two-break unit root test of Lumsdaine and Papell is derived assuming no structural breaks under the null. Thus, rejection of the null does not necessarily imply rejection of a unit root per se, but may imply rejection of a unit root without break. Similarly, the alternative does not necessarily imply trend stationarity with breaks, but may indicate a unit root with breaks. In this paper, we propose an endogenous two-break Lagrange multiplier unit root test that allows for breaks under both the null and alternative hypotheses. As a result, rejection of the null unambiguously implies trend stationarity.

Effects Of Environmental Regulations On Manufacturing Plant Births: Evidence From A Propensity Score Matching Estimator, John A. List, Daniel L. Millimet, Per G. Fredriksson, W. Warren Mchone Jan 2003

Effects Of Environmental Regulations On Manufacturing Plant Births: Evidence From A Propensity Score Matching Estimator, John A. List, Daniel L. Millimet, Per G. Fredriksson, W. Warren Mchone

Faculty Bibliography 2000s

This study examines the effects of air quality regulation on economic activity. Anecdotal evidence and some recent empirical studies suggest that an inverse relationship exists between the stringency of environmental regulations and new plant formations. Using a unique county-level data set for New York State from 1980 to 1990, we revisit this conjecture using a seminonparametric method based on propensity score matching. Our empirical estimates suggest that pollution-intensive plants are responding to environmental regulations; more importantly, we find that traditional parametric methods used in previous studies may dramatically understate the impact of more stringent regulations.

Properties Of Quadratic Multi-Soliton Generation Near Phase-Match In Periodically Poled Potassium Titanyl Phosphate, Sergey Polyakov, Ladislav Jankovic, Hongki Kim, George Stegeman, Silvia Carrasco, Lluis Torner, Mordechai Katz Jan 2003

Properties Of Quadratic Multi-Soliton Generation Near Phase-Match In Periodically Poled Potassium Titanyl Phosphate, Sergey Polyakov, Ladislav Jankovic, Hongki Kim, George Stegeman, Silvia Carrasco, Lluis Torner, Mordechai Katz

Faculty Bibliography 2000s

The properties of the multi-quadratic-soliton generation process have been investigated both theoretically and experimentally near and on phase-match in non-critically-phase-matched, periodically poled, potassium titanyl phosphate (PPKTP). It was found that multi-soliton generation occurs primarily due to asymmetry in the input beam and at phase-matching. The number of solitons generated depended on the input intensity in a non-trivial way.

Regression M-Estimators With Non-I.I.D. Doubly Censored Data, Jian-Jian Ren Jan 2003

Regression M-Estimators With Non-I.I.D. Doubly Censored Data, Jian-Jian Ren

Faculty Bibliography 2000s

Considering the linear regression model with fixed design, the usual M-estimator with a complete sample of the response variables is expressed as a functional of a generalized weighted bivariate empirical process, and its asymptotic normality is directly derived through the Hadamard differentiability property of this functional and the weak convergence of this generalized weighted empirical process. The result reveals the direct relationship between the M-estimator and the distribution function of the error variables in the linear model, which leads to the construction of the M-estimator when the response variables are subject to double censoring. For this proposed regression M-estimator with …
