  • Publication number: 20160101190
    Abstract: Using a novel water-soluble, active ester amide-containing functionalized controlled radical polymerization initiator, stimuli responsive polymers have been grown from the surface of a protein, exemplified by chymotrypsin or any protein having surface amino acids that will covalently bind to the active ester amide-containing functionalized initiator. It is shown that changes in temperature or pH can change the conformation of the polymer surrounding the enzyme, which in turn enabled the rational tailoring of enzyme activity and stability. This method has afforded an increase in the activity and stability of the enzyme by an order of magnitude at pH's where the enzyme is usually inactive or unstable. Multimodal temperature responsive protein-block copolymer conjugates are described.

  • Patent number: 7158455
    Abstract: Servo error signal circuitry apparatus and methods are described. The difference between two bottom envelope signals SEbtm and SFbtm is calculated by a subtracter (40) to generate a difference signal (SEbtm?SFbtm). The difference signal (SEbtm?SFbtm) is input as an alignment signal (AL) to an equalizer (42) and as a basic tracking error signal to the positive input terminal of a second subtracter (52). On the other hand, the difference between two top envelope signals SEtop and SFtop is calculated by a third subtracter (48) to generate a difference signal (SEtop?SFtop). The signal K(SEtop?SFtop) obtained by multiplying a coefficient K with the difference signal using a coefficient multiplier (50) is input to the negative input terminal of the second subtracter (52). The difference signal {(SEbtm?SFbtm)?K(SEtop?SFtop)} output from the second subtracter (52) is used as an offset corrected tracking error signal.
