We report the demonstration of strong (>20 dB) coupling in long-period fiber-gratings over bandwidths as large as 43 nm.

We report the first demonstration of strong (>99%) coupling in long-period fiber-gratings over bandwidths as large as 30 nm.

We present low temperature magnetoconductivity measurements of a density-tunable and high mobility two-dimensional electron gas confined in the wide bandgap GaN/AlGaN system.

We observe that field emitters made from carbon nanotubes exhibit excellent macroscopic emission properties; they can operate at a very large current density, as high as 4 A/cm(2).

Large cyclotron-resonance (CR) line splittings have been observed previously in two-dimensional (2D) electrons in AlGaN/GaN and in GaAs/AlGaAs heterojunctions.

In the standard formulation of the occupancy problem one considers the distribution of r balls in n cells, with each ball assigned independently to a given cell with probability 1/n.

In the standard formulation of the occupancy problem one considers the distribution of r balls in n cells, with each ball assigned independently to a given cell with probability 1/n.

A Large Deviations Principle (LDP), demonstrated for occupancy problems with indistinguishable balls, is generalized to the case in which balls may be distinguished by a finite number of colors.

This article focuses on a queue fed by a large number of "semi-Markov modulated fluid sources", e.g., on/off sources with on and off-times that have general distributions.
