The insulator-metal transition in single crystal La5/8-yPryCa3/8MnO3 with y approximate to 0.35 was studied using synchrotron x-ray diffraction, electric resistivity, magnetic susceptibility, and s

Despite widespread use of multiphoton fluorescence microscopy, development of endoscopes for nonlinear optical imaging has been stymied by the degradation of ultrashort excitation pulses that occur

We introduce minimally invasive multiphoton fluorescence microendoscopes (350-1000 /spl mu/ in diameter) based on compound microlenses.

We extend our studies of microwave photoresistance of ultrahigh mobility two-dimensional electron systems (2DES) into the high-intensity, nonlinear regime employing both monochromatic and bichromat

In this paper we are investigating multiple access schemes and multi-carrier waveforms in the context of future 5G wireless communication systems.

We present a new multiple access concept which allows to accommodate more than N users on a channel of NW Hz bandwidth, where W Hz is the bandwidth of the individual user signals.

A High Data Rate (HDR) system has been proposed for providing downlink wireless packet service by using a channel-aware scheduling algorithm to transmit to users in a time-division multiplexed mann

This paper explores the use of various antenna configurations at the base station for acquisition of the preamble signal sent on a random access channel (RACH) in a 3G wireless network such as UMTS

The system design of the Random Access Channel (RACH) entails three phases: (a) detection algorithm design, (b) dimensioning of resources per cell, (c) resource optimization.

Multiple antenna techniques (beyond two receive antennas at the base station) have now achieved a level of technical maturity that allows their implementation in commercial cellular systems.
