A simple and generalised model — termed the simplistic Chinese box [SCB] model — for the interaction of molecular probes with living systems is described. The SCB model includes the following assumptions. That living systems may be considered as built from biologically defined boxes, e.g. whole cell nucleus nucleoli. That movement of molecular probes into(More)
Orthogonal frequency division multiplexing (OFDM) is a multicarrier modulation scheme that achieves high spectral efficiency by using minimally densely spaced orthogonal subcarriers without increasing the transmitter and receiver complexities. Antenna arrays are a powerful means to exploit the spatial domain to provide an extra layer of co-channel(More)
An arrayed-MIMO communication system, which employs antenna arrays at both ends of the wireless link, is proposed to leverage upon spatial information such as directions-of-arrival to achieve an improvement in performance. This is in contrast with conventional MIMO systems, which typically assume multiple independent antenna elements at the transmitters and(More)
Cultured rat fibroblasts were exposed to 41 cationic fluorescent probes of very varied hydrophilicity/lipophilicity. Outcome of probe-cell interaction fell into one of the following categories: probe failed to enter the cells; probe accumulated on cell surfaces; probe accumulated in mitochondria, and/or in other intracellular regions. The observations were(More)
Multi-Carrier Code Division Multiple Access (MC-CDMA) is a modulation scheme that combines the advantages of OFDM and CDMA to provide robustness against frequency selectivity in wireless channels. Arrayed MC-CDMA systems combine MC-CDMA and antenna array technology to harness the spatial and temporal 'signatures' of received signals, thus making it possible(More)
