Inference of causal interactions among genes known to be involved in the regulation of cell cycle, has received considerable attention in recent years. Capturing the mechanism of gene regulation in the cell cycle is necessary to elucidate both normal and abnormal cell reproduction. Within the last few years, many reverse engineering approaches have been applied to the yeast Saccharomyces cerevisiae...
Dynamic Bayesian networks are of particular interest to reverse engineering of gene regulatory networks from temporal transcriptional data. However, the problem of learning the structure of these networks is quite challenging. This is mainly due to the high dimensionality of the search space that makes exhaustive methods for structure learning not practical. Consequently, heuristic techniques such...
A pulse modulator for ultra-wideband (UWB) transmitters is designed and simulated using 0.13-mum CMOS technology. 8-GHz carrier frequency is modulated into pulses with Gaussian envelope and 1-ns time-width to push the spectrum to 5.8-10.6-GHz band, and to satisfy FCC mask. By using 2-ns pulse-width, it is also possible to utilize the modulator at two sub-bands of 6-8 GHz and 8-10 GHz. The transmitter...
