Multilayer Transcoding with format portability for multicasting of single-layered video
(IEEE, 2005)This paper proposes a novel multilayer video transcoding approach for multicasting pre-encoded video to heterogeneous end-systems via diverse grouping of networks. Multilayer transcoding is first addressed by means of ... -
Efficient Immobilization of a Cadmium Chemosensor in a Thin Film: Generation of a Cadmium Sensor Prototype
(American Chemical Society, 2005)The development of an ion-selective chemosensor for Cd2+ allows generation of a “real-time” sensor. Immobilization of the chemosensor on quartz was achieved in a simple monolayer and in a thin film using a polymer intermediary. ... -
The role of cavitation in acoustically activated drug delivery
(Elsevier Science Direct, 2005)Pluronic P105 micelles are potential candidates as chemotherapy drug delivery vehicles using ultrasonic stimulation as a release trigger. Acoustic power has been previously shown to release two anthracycline agents from ... -
The Comet Assay to Determine the Mode of Cell Death for the Ultrasonic Delivery of Doxorubicin to Human Leukemia (HL-60 Cells) from Pluronic P105 Micelles
(Adenine Press, 2005)This notes examines the mode of cell death of HL-60 cells exposed to 70 kHz and 1.3 W/cm2 ultrasound in the presence of 1% Pluronic P105 and 1.67 μg/ml doxorubicin (Dox). The cells were ultrasonicated for 30, 60, and 120 ... -
