| 20150369660 | SYSTEM, METHOD AND COMPUTER-ACCESSIBLE MEDIUM FOR DEPTH OF FIELD IMAGING FOR THREE-DIMENSIONAL SENSING UTILIZING A SPATIAL LIGHT MODULATOR MICROSCOPE ARRANGEMENT - Exemplary embodiment can utilize the properties of tunable thin-film, material (e.g., graphene) to efficiently modulate the intensity, phase, and/or polarization of transmitted and/or reflected radiation, including mid-infrared (“mid-IR”) radiation. Exemplary embodiments include planar antennas comprising tunable thin-film material sections and metallic sections disposed in contact with the tunable thin-film material sections, each metallic section having a gap with at least one dimension related to a wavelength of the radiation, which in some embodiments may be less than the wavelength. The metallic layer may comprise rods arrange in one or more shapes, or one or more apertures of one or more shapes. Embodiments of the antenna may also comprise a substrate, which may be a semiconductor or conductor in various embodiments. Embodiments also include systems, computer-implemented methods, devices, and computer-readable media for effectuating desired modulation of incident radiation by, e.g., varying the doping level of the tunable thin-film material. | 12-24-2015 |
| 20150299801 | Techniques for Treating Acute Lymphoblastic Leukemia (ALL) - The invention is based on the discovery of certain new somatic single nucleotide substitution mutations of NT5C2 gene variants found in some Acute Lymphoblastic Leukemia (ALL) relapse subjects. Techniques include obtaining a biological sample taken from a subject having ALL, and detecting the presence or absence in the biological sample of a biomarker selected from the group consisting of an NT5C2 gene mutation, an mRNA transcribed from the NT5C2 gene mutation, or a protein encoded by the NT5C2 gene mutation. The method also includes determining that the subject has increased resistance to treatment with 6-mercaptopurine or 6-thioguanine, if the biomarker is detected. In some embodiments, the method still further includes treating the subject with a nucleoside analog other than 6-mercaptopurine or 6-thioguanine if the biomarker is detected. | 10-22-2015 |
| 20150131263 | Inflatable Solar-Powered Light - An inflatable solar-powered light is disclosed. In some embodiments, the inflatable solar-powered light includes the following: an expandable bladder including a plurality of surfaces; a solar-powered light assembly positioned on at least one of the plurality of surfaces of the bladder; and one or more cover portions positioned over the assembly and joined with the at least one of the plurality of surfaces of the bladder around its edges, wherein at least a portion of at least one of the at least one or more cover portions is substantially transparent and each of the one or more cover portions forms a substantially waterproof envelope with the at least one of the plurality of surfaces of the bladder in which the solar-powered light assembly is contained. | 05-14-2015 |
| 20130338496 | MEDICAL IMAGING DEVICES, METHODS, AND SYSTEMS - Devices, methods, and systems for providing optical imaging to detect and characterize anatomical and/or physiological indicators, such as, rheumatoid arthritis, and devices, methods and systems for computer aided detection and diagnosis of tomographic images. Embodiments for optimizing machine classification of tissue samples are described. Embodiments for using machine classification techniques to classify indicators present in optical tomographic images are described. | 12-19-2013 |
| 20120281813 | Confocal Double Crystal Monochromator - A monochromator is adapted to select at least one band of wavelengths from diverging incident radiation. The apparatus includes a first crystal and a second crystal. A band of emitted wavelengths of the first crystal is adapted to the at least one band of wavelengths. A surface curvature of the first crystal is adapted to focus emitted radiation in a first plane. A band of emitted wavelengths of the second crystal also is adapted to the at least one band of wavelengths. Parallel faces of a lattice structure of the second crystal are oriented at a first predetermined angle from a surface of the second crystal. In another embodiment, an apparatus is adapted to select at least one band of wavelengths from diverging incident synchrotron radiation in a given range of wavelengths with an energy resolution finer than about five parts in 10000 and optical efficiency greater than about 50 percent. | 11-08-2012 |
| 20090088482 | Compositions and Methods For Treating Heart Failure - The present invention provides compositions and methods for the following: preventing and treating heart failure; preventing heart failure in a patient with a pre-heart failure condition; treating and preventing heart failure with ischemic and non-ischemic causes; treating and preventing heart failure in a subject status post myocardial infarction; reversing damage to the heart following myocardial infarction; by administering to a subject an effective amount of an adrenergic beta-agonist either alone or in combination with an effective amount of an adrenergic beta-1 antagonist.
