Abstract: A process for curing low-k spin-on dielectric layers based on alkyl silsesquioxane polymers by laser scanning is described wherein curing is achieved by both photothermal and photochemical mechanisms. The layers are deposited by spin deposition, dried and cured by raster scanning with a pulsed laser at energies between 0.1 and 1 Joules/cm.sup.2. Because the laser causes heating of the layer, a nitrogen jet is applied in the wake of the scanning laser beam to rapidly cool the layer and to inhibit oxidation and moisture absorption. The laser induced heating also assists in the discharge of moisture and by-products of the polymerization process. The laser operates at wavelengths between 200 and 400 nm. Insulative layers such as silicon oxide are sufficiently transparent at these so that oxide segments overlying the polymer layer do not inhibit the curing process. Implementation of the laser scanning feature is readily incorporated into an existing spin-on deposition and curing tool.

Abstract: An interconnect line on an IMD layer on a semiconductor device is formed in an interconnect hole in the IMD layer. The interconnect hole has walls and a bottom in the IMD layer. A diffusion barrier is formed on the walls and the bottom of the hole. Fill the interconnect hole with a copper metal line. Perform a CMP step to planarize the device and to remove copper above the IMD layer. Deposit a passivating metal layer on the surface of the copper metal line encapsulating the copper metal line at the top of the hole. Alternatively, a blanket deposit of a copper metal line layer covers the diffusion layer and fills the interconnect hole with a copper metal line. Perform a CMP process to planarize the device to remove copper above the IMD layer. Deposit a passivating metal layer on the surface of the copper metal line encapsulating the copper metal line at the top of the hole in a self-aligned deposition process.

Abstract: The present invention provides a method of diagnosing ulcerative colitis (UC) in a subject suspected of having inflammatory bowel disease by by obtaining a sample from the individual; contacting the sample with human histone H1, or pANCA-reactive fragment thereof, under conditions suitable to form a complex of human histone H1, or pANCA-reactive fragment thereof, and antibody to human histone H1; and detecting the presence or absence of the complex, where the presence of the complex indicates that the individual has UC. The invention also provides related methods of diagnosing a perinuclear anti-neutrophil cytoplasmic antibody positive (pANCA-positive) clinical subtype of UC in a patient with UC. In addition, the invention further provides methods of determining susceptibility to UC in an individual.

Abstract: A two-phase partition system is provided for affinity separation of a composition containing a polysaccharide binding peptide from a mixture such as a fermentation broth. The peptide may be from an enzyme and lacking in polysaccharidase activity such as the binding domain of cellulase that binds to cellulose. The system contains a phase-forming oligosaccharide polymer such as a cellulose derivative to which the peptide binds with a Ka of 10.sup.3 M to 10.sup.7 M, and a phase inducing agent such as a polyethylene glycol polymer, or a salt present at sufficiently high concentration to induce phase separation. If the oligosaccharide polymer is thermoseparating, phase separation can be induced by heating. Using the system involves contacting a composition containing the peptide such as a fusion protein with the system, partitioning the composition into a phase containing the oligosaccharide polymer by binding to the polymer and recovering the polymer containing the bound composition.

Abstract: Dimerization and oligomerization of proteins are general biological control mechanisms that contribute to the activation of cell membrane receptors, transcription factors, vesicle fusion proteins, and other classes of intra- and extracellular proteins. We have developed a general procedure for the regulated (inducible) dimerization or oligomerization of intracellular proteins. In principle, any two target proteins can be induced to associate by treating the cells or organisms that harbor them with cell permeable, synthetic ligands. To illustrate the practice of this invention, we have induced: (1) the intracellular aggregation of the cytoplasmic tail of the .zeta.

Abstract: Transrectal ultrasound is used for accurate planning and targeting of placement of radioactive seeds by needles into the prostate in transperineal prostate brachytherapy. The pubic arch formed by the union of the pelvic bones is a potential barrier to passage of the needles containing the radioactive seeds. An initial image of the pubic arch is also provided by transrectal ultrasound, in addition to a transverse cross-sectional image of the prostate. The initial image of the pubic arch is processed using a technique to selectively enhance the contrast of the linear features of the edge of the ultrasound image. The enhanced image is then thresholded via the use of a percentile thresholding technique and then a curve modeling the shape of the pubic arch is fitted against the thresholded, enhanced image to produce a processed image of the pubic arch. This is then overlaid with the image of the prostate and a determination made as to pubic arch interference.
