Abstract:
A method of treating a subject for acute nicotine withdrawal generally includes intranasally administering to the subject a dose of insulin effective to ameliorate at least one symptom or clinical sign of nicotine withdrawal. In some embodiments, the dose of insulin can be at least 45 IU and no more than 75 IU. In one particular embodiment, the dose can be 60 IU. In some embodiments, the dose can be an amount effective to restore at least a portion of a nicotine-withdrawal-associated decrease in saliva Cortisol level following a stress stimulus. In some embodiments, the dose can be an amount effective to decrease an urge to smoke a cigarette during acute withdrawal from nicotine.
Abstract:
A system and method for designing an antenna wherein a plurality of antenna designs are visually compared using performance metric plots that distinguish between geometries that meet all requirements and designs that do not.
Abstract:
A method includes obtaining a biological sample from an individual, extracting DNA from cells in the sample, measuring the degree of methylation of the extracted DNA at one or more specified loci, and identifying if at least one locus exhibits an alteration in methylation or a degree of methylation that is outside of a normal limit. The method may further include determining whether an individual was exposed to abuse and/or trauma. In some cases, the method further includes treating the individual with a therapy effective to reverse the differential methylation of the DNA.
Abstract:
An AM-FM representation is used to derive AM and FM based equations that can be applied to two consecutive frames in parallel to derive motion estimates. The multidimensional AM-FM representations provide general representations of non-stationary content in digital images. The AM-FM estimate captures single images and features of a video that can lead to different applications in image and video analysis, for example, computer-aided diagnosis in medical applications or monitoring micro-movements of rocky material in the pit slopes.
Abstract:
The present invention provides one or more injection-lockable whistle-geometry semiconductor ring lasers, which may be cascaded, that are integrated on a common silicon-on-insulator (SOI) substrate with a single-frequency semiconductor master laser, wherein the light output from the semiconductor master laser is used to injection-lock the first of the semiconductor ring lasers. The ring lasers can be operated in strongly injection-locked mode, while at least one of them is subjected to direct injection current modulation.
Abstract:
The present invention provides a sensor having, one or more optical slab waveguides having one or more target regions. The target regions may interact with gas molecules or trap, entrain or capture one or more targets of interest. The optical slab waveguides are adapted to receive one or more input optical beams from one or more light sources to create a plurality of propagating optical waves in optical slab waveguide. The propagating optical waves interact with said one or more target regions to create an optical output wavefront that may be in the form of a diffraction pattern. The target regions may be functionalized with an antibody, polymer, cell, tissue, or biological material.
Abstract:
A method to simultaneously detect emission intensity or images at multiple distinct emission wavelengths in the analysis of parallel sample streams in a flow-based analysis system and apparatus for performing the described method.
Abstract:
An larvicide comprising an essential oil encapsulated within a non-viable yeast cell. The larvicide is particially effective against mosquito larvae, non-toxic to humans and other non-target species, inexpensive to make, and non-toxic during manufacture, transport, and storage.
