—This paper introduces a new parallel carrier recovery architecture suitable for ultra-high speed intradyne coherent optical receivers (e.g., ≥ 40Gb/s). The proposed scheme combines a novel low-latency parallel digital phase locked loop (DPLL) with a feedforward carrier phase recovery (CPR) algorithm. The new low-latency parallel DPLL is designed to(More)
Our purpose was to determine the feasibility of comprehensive treatment of the canine prostate with photodynamic therapy (PDT) using motexafin lutetium (Lu-Tex) and to evaluate the toxicity and tissue effects associated with this treatment. Twenty-five adult male beagles with normal prostate glands were given an i.v. injection of the second-generation(More)
BACKGROUND AND OBJECTIVE On-line monitoring of light fluence during intraperitoneal photodynamic therapy (IP PDT) is crucial for safe light delivery. A flat photodiode-based dosimetry system is compared with an isotropic detector-based system in patients undergoing IP PDT. STUDY DESIGN/MATERIALS AND METHODS Flat photodiodes and spherical detectors were(More)
PURPOSE A previous phase I trial of i.p. photodynamic therapy established the maximally tolerated dose of Photofrin (Axcan Pharma, Birmingham, AL)-mediated photodynamic therapy and showed encouraging efficacy. The primary objectives of this phase II study were to determine the efficacy and toxicities of i.p. photodynamic therapy in patients with peritoneal(More)
The optical properties (absorption [mu(a)], transport scattering [mu('s)] and effective attenuation [mu(eff)] coefficients) of normal canine prostate were measured in vivo using interstitial isotropic detectors. Measurements were made at 732 nm before, during and after motexafin lutetium (MLu)-mediated photodynamic therapy (PDT). They were derived by(More)
a-In this paper we propose a new bounded delay retransmission scheme that enhances the reliability of compressed video transmission in multicode DS-CDMA (MC-CDMA) systems. We consider H.263/H.263+ video at low data rates (i.e., <64 kbps) in an IS-95B system over slow fading Rayleigh channels. Our approach is designed to reduce not only packet loss, time(More)
—In channels where the delay spread is smaller than the chip interval (e.g., an IS-95 system operating in indoor environments), spread-spectrum signals do not give rise to path diversity. In this situation, maximal-ratio combiner (MRC) RAKE receivers with resolution reduction (RR) of the diversity receiver branches may be used by the mobile stations to(More)
In channels where the delay spread is smaller than the chip interval, spread spectrum signals do not give rise to path diversity. In this situation, distributed antennas systems may be used to provide path diversity, significantly improving system performance. The interference component caused by the same cell-site users, or interpath interference (IPI), is(More)
