  • Publication number: 20190142892
    Abstract: The invention relates to a chemosynthetic cyclo-hepta modified peptide capable of inhibiting toxins of Staphylococcus aureus and a use thereof. The chemosynthetic peptide can specifically inhibit production of the toxins of Staphylococcus aureus by means of the binding of the RNAIII activator protein by a Staphylococcus aureus autocrine. The invention also relates to the use of the chemosynthetic peptide in the pharmaceutical field. The sequence general formula of the chemosynthetic cyclo-hepta modified peptide is CH3—(CH2)m-X-G-(C-Q-H—W—W—H—W—Y—C)—(R)n-Y. The results show that the modified peptide can be dissolved well in water and has good activity against the toxins of Staphylococcus aureus.

  • Patent number: 10229072
    Abstract: The disclosure is directed to a system and method of managing memory resources in a communication channel. According to various embodiments, incoming memory slices associated with a plurality of data sectors are de-interleaved and transferred sequentially through a buffer to a decoder for further processing. To prevent buffer overflow or degraded decoder performance, the memory availability of the buffer is monitored, and transfers are suspended when the memory availability of the buffer is below a threshold buffer availability.

  • Patent number: 10198063
    Abstract: A power regulation system for a read channel of a data storage assembly includes a first voltage regulator for supplying power to the front-end decoder and a second voltage regulator for supplying power to the back-end codec. The second voltage regulator may conserve power reduce supply voltage to the back-end codec when the codec operates at a lower sampling frequency. The second voltage regulator may additionally increase supply voltage to the back-end codec in conjunction with an increase in sampling frequency. The system may additionally include a third voltage regulator for supplying a memory structure of the read channel with only the minimum required operating voltage to prevent leakage power.

  • Patent number: 10075192
    Abstract: An apparatus for processing data includes a decoder configured to iteratively decode codewords in a data block representing a number of user data sectors, the codewords including user data, folded parity sector data and error correction code parity bits. The folded parity sector data includes a number of parity checks, each with multiple user data bits from each of the data sectors, and with an offset between each of the user data bits from the data sectors determined at least in part by a number of folds in the data sectors. The apparatus also includes a scheduler configured to control decoding of the codewords based at least in part on the folded parity sector data.

  • Patent number: 9817716
    Abstract: Embodiments are related to systems and methods for data processing, and more particularly to systems and methods for multiple codeword processing in a data processing system. An illustrative data processing system includes a processing circuit that processes unprocessed codewords, and provides failed codewords when the processing fails to converge. The system may further include an input buffer circuit that selectively stores a combination of at least one of the unprocessed codewords and at least one of the failed codewords. The input buffer circuit includes a first portion that maintains any of the unprocessed codewords and the failed codewords, and a second portion that maintains only the failed codewords.

  • Patent number: 9786320
    Abstract: A system includes a first sync mark detector circuit operable to apply a first sync mark detection algorithm to search a received media sector and overhead for a second sync mark after a failure to identify a first sync mark. A second sync mark detector circuit operable to apply a second sync mark detection algorithm to search the received media sector and overhead for the second sync mark. An anchor point identification circuit identifies an anchor point in the received media sector. A retry controller circuit causes a re-read of the received media sector and overhead when the first sync mark detector circuit fails to identify the first sync mark, and aligns the received media sector to yield an aligned media sector. A data processing circuit recovers an original user data set from the aligned media sector.
