The histochemical method for the demonstration of D-amino acid oxidase activity in rat liver, based on the use of cerium ions and the diaminobenzidine-cobalt-hydrogen peroxide procedure, was improved by the application of unfixed cryostat sections and a semipermeable membrane interposed between section and gelled incubation medium. The amount of final(More)
It was found to be possible to distinguish malignant cells from normal cells by using an oxygen-sensitive tetrazolium salt (neotetrazolium) for the histochemical demonstration of glucose-6-phosphate dehydrogenase activity in cryostat sections of human colon. We have studied 12 cases of established adenocarcinoma of the colon in addition to 4 of ulcerative(More)
In this paper, we present a novel multiuser detection (MUD) technique based on ant colony optimization (ACO), for synchronous multi-carrier code division multiple access (MC-CDMA) systems. ACO algorithms are based on the cooperative foraging strategy of real ants. While an optimal MUD design using an exhaustive search method is prohibitively complex, we(More)
This paper analyzes the performance of carrier interferometry/orthogonal frequency division multiplexing (CI/OFDM) in the presence of multipath fading as well as jamming. Specifically, the effect of jamming power and jammer bandwidth on the performance of CI/OFDM and OFDM is investigated. While CI/OFDM significantly outperforms traditional OFDM in a fading(More)
