Abstract: Recombinant subunit proteins derived from the MSP-1 C-terminal region of the parasite Plasmodium falciparum are described that have enhanced immunogenic properties. Selected regions of p33 have been combined with p19 to enhance the immunogenic potential of the p19 core region. As the constructs represent discontinuous segments fused to create unique proteins, the recombinant proteins expressed are not found in nature. The enhanced immunogenic potential of the disclosed recombinant proteins provided for strong, consistent and specific antibody responses. The disclosed recombinant subunit proteins are vaccine candidates for protection against infection with malaria.

Abstract: An spectrometer including Raman and LIBS spectroscopy capabilities is disclosed. The spectrometer includes a laser source configurable to produce a lased light directable towards a target substance, the laser source having a single wavelength and having sufficient power to cause a portion of the target to emit Raman scattering and sufficient to ablate a portion of the target substance to produce a plasma plume. A separate remote light collector is optically configurable to collect light emitted from the portion of the target emitting Raman scattering and from the portion of the target producing the plasma plume. A filter is optically coupled to the remote light collector to remove reflected light and Rayleigh-scattered light, and a spectroscope is optically coupled to the filter and configured to separate the collected and filtered light into a frequency spectrum comprising a Raman spectrum and a laser-induced breakdown spectrum. Finally, an electronic light sensor is used to record the frequency spectrum.

Abstract: A novel label-free sensitive detection method by employing a novel sensitive charge sensor is provided. Dissociation constant information is provided by a simple measurement of the dissociation of the target molecule form the target's receptor. The later process is affected by a novel system and its configuration as described herein. Basic objectives are to provide a drug discovery and characterization system that is an improvement over the current state of the art, low cost, highly sensitive, accurate, fast and easy to use. This invention involves both a physical system and a methodology.
Abstract: A three-dimensional composite reinforcement, a three-dimensionally reinforced multifunctional nanocomposite, and methods of manufacture of each are disclosed. The three dimensional reinforcement comprises a two dimensional fiber cloth upon which carbon nanotubes have been grown, approximately perpendicular to the plane of the fiber cloth. The nanocomposite comprises the three-dimensional reinforcement and a surrounding matrix material. Examples illustrate improvements in the through-thickness mechanical, thermal, and electrical properties of the nanocomposite, in addition to substantial improvements in geometrical stability upon temperature changes and vibrational damping, compared to baseline composites reinforced with the two-dimensional fiber cloth alone.

Abstract: Current MRI technologies require subjects to remain largely motionless for achieving high quality magnetic resonance (MR) scans, typically for 5-10 minutes at a time. However, lying absolutely still inside the tight MR imager (MRI) tunnel is a difficult task, especially for children, very sick patients, or the mentally ill. Even motion ranging less than 1 mm or 1 degree can corrupt a scan. This invention involves a system that adaptively compensates for subject motion in real-time. An object orientation marker, preferably a retro-grate reflector (RGR), is placed on a patients' head or other body organ of interest during MRI. The RGR makes it possible to measure the six degrees of freedom (x, y, and z-translations, and pitch, yaw, and roll), or “pose”, required to track the organ of interest. A camera-based tracking system observes the marker and continuously extracts its pose.

Abstract: A spatial Fourier transform spectrometer is disclosed. The Fourier transform spectrometer includes a Fabry-Perot interferometer with first and second optical surfaces. The gap between the first and second optical surfaces spatially varies in a direction that is orthogonal to the optical axis of the Fourier transform spectrometer. The Fabry-Perot interferometer creates an interference pattern from input light. An image of the interference pattern is captured by a detector, which is communicatively coupled to a processor. The processor is configured to process the interference pattern image to determine information about the spectral content of the input light.
Abstract: A slotted TEM transmission line and an in-situ TEM transmission line are utilized to determine both complex permittivity and permeability of soil. The permittivity and permeability information may be used by underground sensing techniques such as GPR and EMI to enhance information from these techniques. The in-situ probe provides that both complex permittivity and permeability can be measured simultaneously over a broad frequency range without disturbing the soil conditions.

Abstract: Logic circuits provide networks to simulate the functions of neural networks of the brain, and can discriminate degrees of state, and combinations of degrees of state, corresponding to a number of neurons. Logic circuits comprise Recursive AND NOT Conjunctions (RANCs), or AND NOT gates. A RANC is a general logic circuit that performs conjunctions for 2n possible combinations of truth values of n propositions. The RANCs function dynamically, with capabilities of excitation and inhibition. Networks of RANCs are capable of subserving a variety of brain functions, including creative and analytical thought processes. A complete n-RANC produces all conjunctions corresponding to the 2n possible combinations of truth values of n propositions.
Abstract: Carbohydrate detectors employing abiotic fuel cell designs are disclosed. The detectors produce current output using reactions between chemical dyes in alkaline solutions and carbohydrates, such as glucose. A linear relationship between current output of the detector and glucose concentration has been observed. This relationship may be used with measurements of current output when the glucose concentration is unknown to determine the unknown glucose concentration. In certain embodiments, the abiotic detectors may further employ electrodes, such as high surface area carbon materials and commercial air breathing electrodes, without the use of catalysts (i.e., precious metals or biocatalytic species) for glucose detection Organic dyes, such as methyl viologen (MV), methylene blue, methylene green, Meldola's blue, indigo carmine, safranin O, and the like, may serve as the electron mediators.
Abstract: Embodiments of the present invention provide polymer matrix nanocomposites reinforced with nano-scale materials such as nanoparticles and carbon nanotubes and methods of fabricating. The nanomaterials are provided within relatively low weight fractions, for example in the range of approximately 0.01 to about 0.4% by weight and distributed within the matrix by a magnetic mixing procedure to provide substantially uniform reinforcement of the nanocomposites. Advantageously, these nanocomposites provide significantly enhanced tensile strength, strain to failure, and fracture toughness over corresponding neat matrices.

Abstract: Systems and methods are disclosed for a modified Sagnac interferometer having a plurality of gratings that can be reflective or transmissive. The gratings allow measurement of wavelength spectra in counter-circulating beams of the interferometer. In one embodiment, diffraction geometries at each pair of neighboring gratings are configured so that diffractive and angular contributions reinforce each other at the second of the pair of gratings. In one embodiment, diffraction geometries at the gratings are configured so that the exiting beams of the interferometer satisfy the crossing condition wherein the exiting beams are on the opposite sides of a reference beam axis for a design wavelength input beam. Also disclosed are techniques for restoring the reinforcement and/or crossing conditions when these conditions are not otherwise met.
