Chengyan Zhao has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8877911
    Abstract: The invention relates to methods and compositions for analyzing plant acetohydroxy acid synthase large subunit (AHASL) genes. In particular, the invention relates to methods for the detection of wild-type AHASL alleles and mutant AHASL alleles that encode imidazolinone-tolerant AHASL proteins. The methods involve the use of PCR amplification and novel compositions comprising allele-specific and gene-specific primers to detect the presence of mutant and/or wild-type alleles present at the individual AHASL genes of a plant. Specifically, the methods and compositions are useful for analyzing the three AHASL genes of Triticum aestivum and the two AHASL genes of Triticum turgidum ssp. durum.

  • Patent number: 8296749
    Abstract: Disclosed are methods, machine readable medium and systems that dynamically translate binary programs. The dynamic binary translation may include identifying a hot code trace of a program. The translation may further include determining a completion ratio for the hot code trace. The translation may also include packaging the hot code trace into a transactional memory region in response to the completion ratio having a predetermined relationship to a threshold ratio.
