Abstract: A device and a method for measuring viscosity that includes attaching molecular rotors to a solid surface, exposing the solid surface to a fluid having a viscosity to be measured, and taking optical measurements to determine viscosity. The solid surface is preferably quartz, polystyrene or silicate glass, such as a fiber optic probe or a glass cuvette. The molecular rotors are of the type that includes an electron-donor group and electron-acceptor group that are linked by a single bond so that the groups may rotate with respect to one another, and that exhibit a fluorescence emission when rotation is hindered.

Abstract: High throughput screening of crystallization of a target material is accomplished by simultaneously introducing a solution of the target material into a plurality of chambers of a microfabricated fluidic device. The microfabricated fluidic device is then manipulated to vary the solution condition in the chambers, thereby simultaneously providing a large number of crystallization environments. Control over changed solution conditions may result from a variety of techniques, including but not limited to metering volumes of crystallizing agent into the chamber by volume exclusion, by entrapment of volumes of crystallizing agent determined by the dimensions of the microfabricated structure, or by cross-channel injection of sample and crystallizing agent into an array of junctions defined by intersecting orthogonal flow channels.

Abstract: A power combiner comprising an LC lattice structure is shown, together with a method for generating a planar wave front. The LC structure can comprise constant or voltage dependent capacitors. Either the delay or the characteristic impedance of the two-dimensional transmission line formed by the LC lattice structure are kept constant. A planar wave propagating along one direction of the transmission line gradually experiences higher impedances at the edges, creating a lower resistance path for the current in the middle. This funnels more power to the center as the wave propagates.

Abstract: The present invention provides methods of producing an isoprenoid or an isoprenoid precursor in a genetically modified host cell. The methods generally involve modulating the level of hydroxymethylglutaryl-CoA (HMG-CoA) in the cell, such that the level of HMG-CoA is not toxic to the cell and/or does not substantially inhibit cell growth, but is maintained at a level that provides for high-level production of mevalonate, IPP, and other downstream products of an isoprenoid or isoprenoid pathway, e.g., polyprenyl diphosphates and isoprenoid compounds. The present invention further provides genetically modified host cells that are suitable for use in a subject method. The present invention further provides recombinant nucleic acid constructs for use in generating a subject genetically modified host cell, including recombinant nucleic acid constructs comprising nucleotide sequences encoding one or more mevalonate pathway enzymes, and recombinant vectors (e.g., recombinant expression vectors) comprising same.

Abstract: Biomarker proteins that can be used in the diagnosis of early-stage ovarian cancer (OC) are described. The biomarker panels not only permit the distinction of patients with ovarian neoplasia (benign or malignant) from normal subjects, but they also allow the identification of patients with early-stage (stage I/II) ovarian cancer from those patients with benign ovarian tumors or normal individuals. The invention additionally provides methods for detecting and treating various cancers, including cancer of the ovary using OC-related molecules.

Abstract: A single absorbance value was found in the mid infrared (mid-IR) region that correlated directly to soil nitrate content while not being influenced by other components in the soil, such as carbonate and organic matter. Using one or two absorbance values, at which interference from other ions is a minimum, to predict a component's concentration as opposed to the conventional method of using a continuous spectrum allows for an in-situ real-time soil nitrate content sensor.

Abstract: This invention provides methods for detecting cancers and for evaluating the prognosis of cancer patients. In particular, the methods of this invention utilize YKL-40 as a marker for the presence or absence of a cancer and for the prognosis (e.g. likelihood of recurrence) of a cancer. Elevated levels of YKL-40 are indicative of the presence of a cancer in undiagnosed subjects and indicate likely recurrence of the cancer in subjects diagnosed as having a cancer.

Abstract: Presented herein are methods, systems, devices, and computer-readable media for systems for dynamic management of data streams updating displays. Some of the embodiments herein generally relate to presenting video image data on an array of tiled display units, thereby allowing the display of much larger images than can be shown on a single display. Each display unit can include a video image display, a communication mechanism, such as a network interface card or wireless interface card, and a video image controller, such as a graphics card. Attached to the tiled display may be one or more user computers or other sources of video image data. A workstation may also be coupled to the tiled display and to the user computers. Each of the user computers can display data or images on the tiled display simultaneously. Since the tiled display is made up of multiple display units, the images from a single user computer may be on multiple, separate individual display units.

Abstract: The present invention relates to methods for prognosis, diagnosis, and treatment of malignant tumors that were treatment resistant. The present invention provides methods of prognosis and diagnosis of multidrug resistant tumors through detection of the expression levels of nuclear co-repressor 2 (“N-CoR2”), histone deacetylases 3 (“HDAC3”), and their associated gene expression biomarkers. The present invention also provides methods of sensitizing tumors to anti-tumor therapeutics by disrupting HDAC3 activation, abrogating the N-CoR2-HDAC3 interaction, inhibiting the activity of either protein, or by down-regulating the expression of either protein.

Abstract: Misfit dislocations are redirected from the buffer/Si interface and propagated to the Si substrate due to the formation of bubbles in the substrate. The buffer layer growth process is generally a thermal process that also accomplishes annealing of the Si substrate so that bubbles of the implanted ion species are formed in the Si at an appropriate distance from the buffer/Si interface so that the bubbles will not migrate to the Si surface during annealing, but are close enough to the interface so that a strain field around the bubbles will be sensed by dislocations at the buffer/Si interface and dislocations are attracted by the strain field caused by the bubbles and move into the Si substrate instead of into the buffer epi-layer. Fabrication of improved integrated devices based on GaN and Si, such as continuous wave (CW) lasers and light emitting diodes, at reduced cost is thereby enabled.
