Abstract:

A computer-implemented method as follows. Providing a list of target sequences associated with one or more organisms. Providing a list of candidate prototype sequences suspected of hybridizing to one or more of the target sequences. Generating a collection of probes corresponding to each candidate prototype sequence, each collection of probes having a set of probes for every subsequence. The sets consist of the corresponding subsequence and every variation of the corresponding subsequence formed by varying a center nucleotide of the corresponding subsequence. Generating a set of fragments corresponding to each target sequence. Calculating the binding free energy of each fragment with a perfect complimentary sequence of the fragment. Determining which extended fragments are perfect matches to any of the probes. Assembling a base call sequence corresponding to each candidate prototype sequence.

US Classification:

385 6, 385129

Abstract:

A waveguide structure is provided. The waveguide structure includes a photonic crystal structure comprising gyromagnetic materials arranged in a two-dimensional lattice formation that exhibits a plurality of one-way modes produced as a result of magneto-optic effects. One or more confining barriers are positioned around the photonic crystal structure so as to allow the one-way modes to propagate through the photonic crystal structure. One or more radiation sources are positioned in or around the photonic crystal structure so as to couple electromagnetic energy into and out of the waveguide. One or more static external magnetic field sources induce the magneto-optic effects such that the one-way modes are allowed to propagate in one direction in the photonic crystal structure.

Abstract:

Disclosed is a doped cerium oxide sorbent that can effectively and regenerably remove HS in the temperature range of about 500 C. to about 1000 C. Regenerable sorbents (e. g. , ZnO, LaO, CeO) and methods of using them are disclosed that allow cyclic desulfurization from about 300-500 C. , 350-450 C. , and at about 400 C. In one embodiment, the present invention relates to a method of desulfurizing fuel gas comprising passing the fuel gas through the sorbent at a space velocity wherein the sulfur compounds are adsorbed substantially on the surface of the sorbent; and regenerating the sorbent by passing a regenerating gas through the sorbent, wherein substantially all of the sulfur compounds are desorbed from the sorbent surface. In a further embodiment, the method of desulfurizing fuel gas further comprises repeating the aforementioned steps while the fuel processor is in operation. In another embodiment, the step of passing the fuel gas may be preceded by reducing the sorbent by passing a reducing gas through the sorbent.

US Classification:

356 401, 356 301, 356 315, 356 41, 356 501, 356 51

Abstract:

This invention relates to a three-dimensional image of ground surface and the method and system that generates the three-dimensional image. Here, a three-dimensional image is an image that has three-dimensional XYZ coordinates in a ground coordinate system for every pixel of the image and the ground surface means the bare-earth surface plus all the objects on the bare-earth surface. The scene covered and represented by such a three-dimensional image is a three-dimensional real world scene where everything visible in the three-dimensional image has three-dimensional coordinates. The three-dimensional XYZ coordinates of all the pixels of a three-dimensional image are attributed by the method and system of this invention for generating three-dimensional images with airborne oblique/vertical imagery, GPS/IMU, and LIDAR ground surface elevation or range data. On such a three-dimensional image, one can make direct measurements of location, length, distance, height, area, and volume and indirect measurements including but not limited to profile and sight of view all in the real world three-dimensional coordinate system. Additionally, application systems that utilize three-dimensional images can make three-dimensional displays or perspective views of the ground surface with fly-through or walk-through, rotations and zoom in and out, and three-dimensional manipulation and simulation of ground surface.

Abstract:

This invention relates to a product called unified spectral and geospatial information model and the method and system that generates the model. Here, the model comprises an airborne image of ground surface. The image in such a model has three-dimensional XY2 coordinates for every pixel of it and particularly multiple pixels of the image can have same XY coordinates. The XYZ coordinates of all the pixels of the image are uniquely attributed by the method and system presented in this invention. An image of the unified spectral and geospatial information model always covers a scene of ground surface. And, all objects visible in such a scene are measurable in terms of both radiometry and geometry. The unified spectral and geospatial information model can be made by the method and system of this invention with airborne imagery, GPS/IMU data, and ground surface elevation or range data.

Abstract:

A nano-optomechanical transducer provides ultrabroadband coherent optomechanical transduction based on Mach-wave emission that uses enhanced photon-phonon coupling efficiencies by low impedance effective phononic medium, both electrostriction and radiation pressure to boost and tailor optomechanical forces, and highly dispersive electromagnetic modes that amplify both electrostriction and radiation pressure. The optomechanical transducer provides a large operating bandwidth and high efficiency while simultaneously having a small size and minimal power consumption, enabling a host of transformative phonon and signal processing capabilities. These capabilities include optomechanical transduction via pulsed phonon emission and up-conversion, broadband stimulated phonon emission and amplification, picosecond pulsed phonon lasers, broadband phononic modulators, and ultrahigh bandwidth true time delay and signal processing technologies.
