Abstract: Azidoaryl-substituted cyclooctene monomers and synthesized and used in the preparation of various copolymers. Among these copolymers are those prepared from ring-opening metathesis polymerization of cyclooctene, polyethylene glycol-substituted cyclooctene, and azidoaryl-substituted cyclooctene. These copolymers are useful in the formation of crosslinked films that reduce fouling of water purification membranes.

Abstract: The present invention provides a system and methods for analyzing the function of nucleotide integrases and modified group II introns. The system comprises a donor plasmid comprising a wild-type or modified group II intron, a recipient plasmid comprising a DNA recognition site and a promoterless reporter gene downstream of the DNA target site, and a host cell. The method comprises the steps of transforming a host cell with the donor and recipient plasmids, assaying for expression of the reporter gene, isolating plasmid DNA from the cotransformed cells, and analyzing the plasmid DNA to confirm that the group II intron has been inserted into the target sequence. The present invention also provides a method for simultaneously analyzing the activity of two or more modified nucleotide integrases. The present invention also relates to methods of preparing a library of donor plasmids containing a plurality of diverse modified group II intron DNA sequences.

Abstract: An apparatus to control displacement of a body spaced-apart from a surface includes a flexure system having a first flexure member defining a first axis of rotation and a second flexure member defining a second axis of rotation. A body is coupled to the flexure system to move about a plurality of axes. An actuation system is coupled to the flexure system to selectively constrain movement of the body along a subset of the plurality of axes.

Abstract: Disclosed herein is an automatic fluid dispensing method and system for dispensing fluid on the surface of a plate-like material, or substrate, including a semiconductor wafer for imprint lithography processes. The dispensing method uses fluid dispenser and a substrate stage that may generate relative lateral motions between a fluid dispenser tip a substrate. Also described herein are methods and devices for creating a planar surface on a substrate using a substantially unpatterned planar template.

Abstract: Computationally efficient DTMF detection methods and apparatus are presented that meet all of the ITU recommendations using the modified non-uniform DFT. The system of the present invention employs a high band filter block and two low band filter blocks to detect power at the 8 DTMF tones. The frame length of the high band filter blocks is one half the length of the low band filter blocks. The frame lengths are chosen to meet the ITU frequency selectivity requirements for all DTMF frequencies. The frames of the two low band filter blocks are staggered to produce outputs alternately, and are aligned with respect to the frame of the high band filter block to produce low band filter block outputs that coincided with the high band filter block outputs without the need for signal buffering. A system of power level tests are employed in conjunction with a system of timing tests to ensure that all ITU timing and frequency constraints are met.

Abstract: The invention provides methods and compositions for inducing and detecting signal transduction through LDL receptors, including specifically detecting a stress that alters a functional interaction of a low density lipoprotein (LDL) receptor binding polypeptide with an LDL receptor interaction domain, by (a) introducing a predetermined stress into a system which provides a physical interaction of an LDL receptor binding polypeptide with an LDL receptor intracellular binding polypeptide interaction domain, whereby the system provides a stress-biased interaction of the binding polypeptide and the interaction domain, wherein the absence of the stress, the system provides a unbiased interaction of the binding polypeptide and the interaction domain; and (b) detecting the stress-biased interaction of the binding polypeptide and the interaction domain, wherein the binding polypeptide is selected from SEMCAP-1, JIP-1, PSD-95, JIP-2, Talin, OMP25, CAPON, PIP4,5 kinase, Na channel brain 3, Mint1, ICAP-1 and APC subunit1

Abstract: The present invention involves a process for screening for and isolating spontaneously occurring or induced cellulose II-producing microorganisms. The process comprises a series of steps in various embodiments. Initially, cellulose-producing microorganisms from a first culture are plated out on a nutrient agar plate. The nutrient agar plate is then incubated to facilitate formation of colonies from single microorganisms. Samples of liquid nutrient medium are then inoculated with microorganisms from colonies having a smooth configuration, as compared to the usual rough colony configuration. The inoculated samples are then aerobically incubated to facilitate microorganism proliferation and pellicle formation. From these incubated samples are selected microorganisms, which, after a cultivation period, have proliferated but not formed a pellicle. Said selected microorganisms produce cellulose II instead of the cellulose I produced by pellicle-forming organisms.
