A confocal laser scanning microscopy method has been developed for the quantitation of green fluorescent protein (GFP) as a reporter of gene activity in living three-dimensional structures such as sea urchin and starfish embryos. This method is between 2 and 50 times more accurate than conventional confocal microscopy procedures depending on the… (More)
This work presents a noise cancellation structure with a fixed beamformer front end. Simulation results show a noise reduction of 21 dB with a speech source-noise source separation of 1m. Moreover, experimental results (real data acquired in a reverberant conference room) show a complex noise reduction pattern with a maximum noise reduction of 17 dB.
