摘要： An optical receiving apparatus includes: an A/D converting circuit; a received-signal demodulating circuit that demodulates a received digital signal from the A/D converting circuit into an m-bit received signal; a soft-decision-data generating circuit that generates n-bit (n≦m) soft-decision data based on the m-bit received signal; and an error correcting circuit that performs error correction based on the n-bit soft-decision data and outputs an error-corrected received signal. The soft-decision-data generating circuit generates soft-decision data of n bits (n=p+1) that corresponds to a determination result according to 2n−1 soft-decision thresholds, by using an MSB of the m-bit received signal as hard-decision data, and by using, as reliability information, a result of comparison between a plurality of bits (k bits, where k≦m) on an MSB side of the m-bit received signal and a fixed threshold, or p bits (p≦m−k) selected from (m−k) bits on an LSB side of the m-bit received signal.

摘要： A full-length cDNA encoding novel proteins involved in the control of cell proliferation (human Gros1-L and S) was successfully isolated from the human testis cDNA libraries. A full-length cDNA encoding the mouse homologues of the human Gros1 (mouse Gros1-L and S) was also isolated. The colony forming activity of cells exogenously expressing Gros1-L was significantly reduced, while that of cells expressing Gros1 antisense RNA was significantly increased.

摘要： If no alarm is input from an optical receiver, an FEC decoder, or a client signal monitor, a control circuit controls a variable dispersion equalizer such that a transmission error becomes smaller using information on the number of error corrections obtained from the FEC decoder and fixes a dispersion equalization value in the event that the error becomes equal to or lower than a specified value. If the alarm information is input, the control circuit switches control over the variable dispersion equalizer from an ordinary control to a search mode control for searching an optimal dispersion equalization value in a wide range to thereby search the optimal dispersion equalization value at a higher speed.

摘要： A gene expressed specifically in the testis has been unexpectedly isolated in the course of studies of the expression of a gene encoding an unknown protein that triggers cell death. The isolated gene was a novel gene sequence that had no significant homologue in the database. This gene was also found to be involved in the regulation of differentiation in the testis and to encode a protein, Tesmin, which may regulate the differentiation of spermatogeneous cells into primary spermatocytes. Tesmin proteins are described herein, as are antibodies that bind to such proteins.
