Extremum-seeking control via sliding mode with periodic search signals

Hai Yu, +1 more
TL;DR: In this paper, the authors provide the proof of the stability of an extremum-seeking control scheme enforced by a sliding mode control strategy with periodic search signals, and the stability conditions are given for a general plant modeled as a static nonlinear map possibly cascaded with a linear dynamic block.
Journal ArticleDOI

Pasteurella multocida CMP-sialic acid synthetase and mutants of Neisseria meningitidis CMP-sialic acid synthetase with improved substrate promiscuity

Yanhong Li, +6 more
- 01 Mar 2012 - 
TL;DR: The cloning, characterization, and substrate specificity studies of a new CSS from Pasteurella multocida strain P-1059 and a CSS from Haemophillus ducreyi with improved substrate promiscuity were reported, indicating a general approach for designing enzyme mutants with improved activity and substrate Promiscuity.
Journal ArticleDOI

Efficient chemoenzymatic synthesis of sialyl Tn-antigens and derivatives

Li Ding, +6 more
- 19 Jul 2011 - 
TL;DR: An N- terminal and C-terminal truncated recombinant α2-6-sialyltransferase cloned from Photobacterium sp.
Journal ArticleDOI

Efficient chemoenzymatic synthesis of biotinylated human serum albumin-sialoglycoside conjugates containing O-acetylated sialic acids.

Hai Yu, +3 more
- 18 Jul 2007 - 
TL;DR: This approach provides an efficient and general protocol for preparing carbohydrate-protein conjugates containing base-sensitive groups.
Journal ArticleDOI

Polyclonal human antibodies against glycans bearing red meat-derived non-human sialic acid N-glycolylneuraminic acid are stable, reproducible, complex and vary between individuals: Total antibody levels are associated with colorectal cancer risk.

Annie N. Samraj, +17 more
- 18 Jun 2018 - 
TL;DR: The finding of a positive association of total anti-Neu5Gc antibodies with CRC risk also warrants confirmation in larger prospective studies, as these antibodies have potential as biomarkers for diseases associated with red meat consumption such as carcinomas, atherosclerosis, and type 2 diabetes.
