The invention relates generally to methods of influencing central nervous system cells to produce progeny useful in the treatment of CNS disorders. More specifically, the invention includes methods of exposing a patient suffering from such a disorder to a reagent that modulates the proliferation, migration, differentiation and survival of central nervous system cells. These methods are useful for reducing at least one symptom of the disorder.
摘要:
A system and method are set forth for remotely controlling a presentation in a loop mode to allow the presentation to continue in the absence of a communication channel between the portable electronic device and remote presentation device. In particular, the portable electronic device can issue a command to the remote presentation device to present the presentation in loop mode so that a user of the portable electronic device can leave the vicinity of the remote presentation device (e.g. out of communication range) while the presentation plays in loop mode.

A molecular interferometric imaging system for detecting an analyte in a sample, that includes an illumination source providing a beam of radiation; a pixel array for detecting radiation in an image plane; a biolayer designed to react to the analyte when it comes in contact with the sample; a substrate designed to convert phase modulation into intensity modulation which can be detected and imaged directly by the pixel array, the biolayer being on the substrate; a reference surface; an image switching means for switching between a first position for collecting a sample image of the biolayer, and a second position for collecting a reference image of the reference surface; and a processing means for producing a composite image using the sample image and the reference image for illumination normalization.
摘要:
A system and a method for forming a cell by using distributed antennas in a World interoperability for Microwave Access (WiMAX) mobile communication system supporting a broadband wireless access communication system. A virtual cell is formed with a specific Mobile Station (MS) as a central part of the virtual cell by using distributed antennas, which improves the transmission capacity and the performance of an overall network system without changing the structure of a backbone network and the interface of the overall network system. The system includes, multiple MSes; distributed antennas for perform simultaneous communications with at least one MS among the multiple MSes, and for forming one virtual cell by communicating with the multiple MSes; and a Base Station (BS), which is typically connected to the distributed antennas through optical fibers, for communicating with the MSes.
摘要:
A head including a write element for writing data to a magnetic media, and methods for its production are provided. A write element of the invention includes one or more of a recessed first pole, a heat sink layer, and a shortened yoke length. A method of the invention provides forming an anti-reflective layer before forming a mask layer. During photolithography the anti-reflective layer suppresses undesirable reflections off of features, such as vertical sidewalls, that otherwise limit how closely to such features portions of the mask layer can be formed.

摘要:
A phase contrast quadrature interferometric method for determining the presence or absence of a target analyte in a sample. The method comprises using a laser beam having a wavelength λ and a waist wo to probe at least a portion of a substrate having a reflecting surface that has been exposed to the sample. The reflecting surface includes at least a first region having a layer of recognition molecules specific to the target analyte and a second region that does not include a layer of recognition molecules specific to the target analyte. The method further comprises measuring a time dependent intensity on a photodetector of a substantially only first quadrature at one of a pair of quadrature angles ⊖q of a reflected diffraction signal of the probe beam while probing the first region and the second region. An apparatus for phase-contrast quadrature interferometric detection of the presence or absence of a target molecule on a planar array, comprises a laser source for generating a probe beam. The apparatus includes a platform for receiving the planar array and a first optical train for directing the probe beam at the platform in a substantially surface normal manner. The apparatus also includes an objective lens having a first side and a second side and having a focal length, the objective lens being offset on the first side of the lens from the platform by a first distance approximately equal to the focal length. The apparatus further includes split photodetector means for measuring a first quadrature and a second quadrature in a signal resulting from reflection of the probe laser beam.
