Patent number: 8877911Abstract: 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.Type: GrantFiled: June 19, 2012Date of Patent: November 4, 2014Assignee: BASF SEInventors: Chengyan Zhao, Robert Ascenzi, Bijay K. Singh

Patent number: 8296749Abstract: 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.Type: GrantFiled: December 28, 2007Date of Patent: October 23, 2012Assignee: Intel CorporationInventors: Chengyan Zhao, Cheng Wang, Youfeng Wu
