The reconstruction of genetic networks in mammalian systems is one of the primary goals in biological research, especially as such reconstructions relate to elucidating not only common, polygenic human disease, but living systems more generally. The present invention provides novel gene network reconstruction algorithms that utilize naturally occurring genetic variations as a source of perturbations to elucidate the networks. The algorithms incorporate relative transcript abundance and genotypic data from segregating populations by employing a generalized scoring function of maximum likelihood commonly used in Bayesian network reconstruction problems. The utility of these novel algorithms can be demonstrated via application to gene expression data from a segregating mouse population. The network derived from such data using the novel network reconstruction algorithm is able to capture causal associations between genes that result in increased predictive power, compared to more classically reconstructed networks derived from the same data.

A communication system and a timing control method are proposed that optimize timing in a sender and thereby enable information to be stably transmitted at the right timing. Under instructions from a timing controller in a receiver, the timing of driving a phase modulator in a sender is shifted by one step after another, and the then amount of clock shift and result of interference are monitored at the receiver and stored in a memory.

Additionally, embodiments of the present invention can allow patterning devices to be made to more exacting tolerances because some patterning devices may have a higher capability along one axis than another. Embodiments of the present invention also include a semiconductor device having like-functioned I/O cells arranged such that their layouts and rotational orientations with respect to their corresponding core remain constant. Furthermore, disclosed semiconductor devices may include at least one circuit cell having non-parallel features, where the circuit cell is arranged either within the core or within a corresponding interface circuit cell.
