摘要： Methods, apparatus and systems that relate to a portable chromatic light microscope are described. One example chromatic light microscope includes a light source including light producing elements that produce non-monochromatic output light that can be modulated. The chromatic light microscope further includes an illumination subsection to receive light that is output from the light source. The illumination subsection includes one or more lenses to spatially disperse spectral contents of the light that is received by the illumination subsection and to deliver light having chromatic aberration to a target object. The chromatic light microscope also includes an imaging subsection that includes one or more lenses to receive scattered light from the target object and to deliver the same to a sensor, and a linear variable filter to selectively pass a portion of the light having a particular spectral range of wavelengths to the sensor.

摘要： Methods and frameworks for designing and optimizing of high-performance light field displays, such as integral imaging head-mounted displays, are disclosed. The disclosed techniques enable user-defined metrics for characterizing the performance and optimization of such systems. One design method relates to an integral-imaging based three-dimensional (3D) display system that includes an arrayed optics, an arrayed display device to produce a plurality of elemental images, a first reference plane representing a virtual central depth plane (CDP), a second reference plane representing a viewing window for viewing a reconstructed 3D scene, and an optical subsection representing a model of a human eye. The method includes tracing rays starting at the arrayed display device, through the arrayed optics, and to the optical subsection for each element of the arrayed display device and arrayed optics, and adjusting one or more parameters to obtain at least a first metric value within a predetermined value.

摘要： A design and implementation of a new optical architecture: space, time, and angular division multiplexed image transfer by Digital Micromirror Device. The method, like various multiplexing methods employed in communication engineering, enables image transfer via an angular band-limited data channel such as an optical image guide by dynamically redistributing a signal into multiple domains such as space, time, angle, wavelength, and polarization.

摘要： A phyto-mediated wastewater treatment bioreactor (PWBR) for treating wastewater effluent and agricultural effluent is disclosed herein. The PWBR is used to clean and remove emerging contaminants from water. These emerging compounds include, but are not limited to, pharmaceutical compounds, steroids and hormones, and industrial and household chemicals. Plants and/or the microorganisms adhering to the plant roots and their growing medium have the ability to take up many of these contaminants and the PWBR maximizes their treatment capability in a given space and time.

摘要： This invention provides methods utilizing ketamine for the treatment of motor disorders and/or side effects associated with certain medications used in the treatment of motor disorders. For example, in some embodiments, methods are provided for treating side effects associated with the administration of levodopa to a subject having Parkinson's disease, by administering a dose of ketamine or a pharmaceutically acceptable salt thereof. In particular, the invention provides methods for reducing dyskinesia associated with motor disorder (e.g., Parkinson's disease) treatments, and effective doses of ketamine or a pharmaceutically acceptable salt thereof.

摘要： A light projection system includes an angle-dependent pattern projection device projecting light of multiple patterns into corresponding multiple directions, and a waveguide comprising an input and an output, configured to accept the light from the angle-dependent pattern projection device and emit the light through the output, whereby the light from each of the multiple patterns takes a unique path through the waveguide. The waveguide is built into a headset display device, and the output of the waveguide couples light emitted through the output to an eye.

摘要： Systems and methods for providing oxygenated blood to a patient, e.g., in a patient with inadequate or failing circulation, including a dual lumen cannula system for drawing blood from the heart and returning oxygenated blood therein. Methods may feature inserting the dual lumen cannula system through the left ventricle such that intake aperture are positioned entirely within the left ventricle and the tip of the cannula is positioned in the aorta of the patients heart. By fluidly connecting the cannula to a cardiac assistance device, deoxygenated blood may be drained from the left ventricle through the intake apertures and oxygenated blood may be pumped into the aorta thorough the tip.

摘要： A modular microfluidic device for simulating in vivo conditions of a biological system may include a first perfusion chamber having an inlet and an outlet, a second perfusion chamber having an inlet and an outlet, a well configured to hold one or more 3D structures of cultured biological cells. The well may be in fluid communication with the first and second perfusion chambers. A first porous membrane may be disposed between the first perfusion chamber and the well. A second porous membrane may be disposed between the second perfusion chamber and the well. The well may be configured to facilitate growth of cultured biological cells along all three dimensional axes, thereby providing or ensuring a more representative 3D structure of biological cells compared to conventional monolayer cultures.

摘要： The present invention provides a process for producing a nanocomposite particle (“nanoSCINT particle”) adapted for use in scintillating proximity assay in a relatively high quantity. The nanoSCINT particle comprises a silica shell that encapsulates a nanoparticle organic polymer that is doped with at least one scintillating compound. In particular, the process of the invention includes adding a plurality of batch-wise portions of a polymerization initiator to an emulsion comprising a relatively high amount of polymerizable organic compound to produce a nanoparticle organic polymer, which is then doped with at least one scintillating compound, and then encapsulated with a silica shell to produce nanoSCINT particles in gram quantities in a single process. Unlike conventional methods, a single process of the invention provides at least about 5 g, typically at least about 7.5 g, and often at least about 10 g of nanocomposite particles.

摘要： A label-free detection and characterization system includes an optical source; an optical path arranged to be optically coupled to the optical source; an optical resonator disposed proximate the optical path along a side of the optical path, the optical resonator having an optical whispering-gallery mode and being optically coupled to the optical path through an evanescent field to excite the optical whispering-gallery mode; an optical receiver arranged to be optically coupled to the optical path. The optical source is frequency locked to a resonance frequency of the optical resonator and provides light sufficiently intense to provide four-wave mixing while being coupled with the optical resonator resulting in a comb spectrum received by the optical receiver. The comb spectrum provides characteristic changes in the presence of a substance in contact with the optical resonator to provide detection and characterization of the substance.
