Vortices and defect statistics in two-dimensional optical chaos
We present the first direct experimental evidence of topological defects in nonlinear optics. For increasing Fresnel numbers F, the two-dimensional field is characterized by an ...

Risk assessment in conservation biology
Population viability analysis (PVA) has become one of the standard tools of conservation biology. Unfortunately, few examples have entered the refereed literature. Most remain i...
The tunnel effect correction for parabolic potential barriers
The first page of this article is displayed as the abstract.
Behavior of neutral atoms in a spontaneous force trap
A classical collective behavior is observed in the spatial distributions of a cloud of optically trapped neutral atoms. They include extended uniform-density ellipsoids, rings o...
Optical Transmission in Disordered Media
The scale dependence of transmission in wedged random media containing titania microstructures is measured. The diffusion coefficient and absorption length are determined from t...
Quantum scattering in two dimensions
A self-contained discussion of nonrelativistic quantum mechanical potential scattering in two dimensions is presented. The discussion includes, among other topics, partial wave ...
The Information Technology Interaction Model: A Foundation for the MBA Core Course
This paper presents a teaching model that has been used successfully in the MBA core course in information systems at several universities. The model is referred to as the "Info...
An architecture for large scale Internet measurement
Historically, the Internet has been woefully under-measured and under-instrumented. The problem is only getting worse with the network's ever-increasing size. We discuss the goa...
Large-Scale Ni-Doped ZnO Nanowire Arrays and Electrical and Optical Properties
Large-scale Ni-doped ZnO nanowire (NW) arrays are grown. The electrical conductivity of a single Ni-doped ZnO NW has been increased for 30 times. The photoluminescence (PL) spec...
THE NONLINEAR OPTICAL PROPERTIES OF Ba2NaNb5O15
The useful nonlinear coefficients of Ba2NaNb5O15 are approximately twice those of LiNbO3. This material is a filled (A sites) structure composition and at room temperature does ...
Photonic band-gap crystals
The analogy between electromagnetic wave propagation in multidimensionally periodic structures and electron wave propagation in real crystals has proven to be a very fruitful on...
Single molecule detection and photochemistry on a surface using near-field optical excitation
We report the first photobleaching experiments of single molecules on a surface. Single molecules of rhodamine 6G are detected on a silica surface under ambient conditions using...
