Abstract: Systems and methods for network management in a virtual environment are presented. The system and methods may include or utilize a top of rack router and a plurality of nodes within a virtual network environment, and an extensible network control plane that is extendable from the top of rack router to the plurality of nodes. Upon receipt of a data packet at the top of rack router, information regarding the packet's desired endpoint address can be determined and a unique endpoint address within the environment covered by the control plane created such that the packet can be directly routed to the desired endpoint without the need for intermittent hops to non-endpoint pods, etc. Hardware solutions may be utilized to eliminate latencies in the process. Data packet flows may also be identified and used to further reduce latencies.

Abstract: A device, and method, for situational awareness of an emergency scene for first responders uses an unmanned aerial vehicle equipped with a sensor package in populated or otherwise restricted areas. The unmanned aerial vehicle is assigned to a control center for a designated incident while automatically tasking the unmanned aerial vehicle with the initiation of the incident response to autonomously proceed to the incident prior the control center taking active control of the unmanned aerial vehicle.

Abstract: Determination of the morphology and motility of a population of cells in vitro is possible via a series of steps. The cells are imaged using a microscope and camera. A first frame of image data allows identification of parts of the image data corresponding to a cell or cells of interest. Cell morphology is determined from this data. A second frame of image data, captured subsequent to the first, allows the determination of the relative displacement of the cell or cells of interest. This provides motility data. The invention has particular application in male fertility investigations.

Abstract: It has been surprisingly discovered that administration of nitrite to subjects causes a reduction in blood pressure and an increase in blood flow to tissues. The effect is particularly beneficial, for example, to tissues in regions of low oxygen tension. This discovery provides useful treatments to regulate a subject's blood pressure and blood flow, for example, by the administration of nitrite salts. Provided herein are methods of administering a pharmaceutically-acceptable nitrite salt to a subject, for treating, preventing or ameliorating a condition selected from: (a) ischemia-reperfusion injury (e.g., hepatic or cardiac or brain ischemia-reperfusion injury); (b) pulmonary hypertension (e.g., neonatal pulmonary hypertension); or (c) cerebral artery vasospasm.

Abstract: An apparatus for dry cutting asphalt, concrete and other hard construction materials. The apparatus has a forward direction of operation and includes a circular saw, blade guard, and vacuum collection means. The circular saw includes a housing having front and back ends, a rotatable shaft extending from the housing, a blade fixed to the shaft, and means for rotating the shaft and blade in a direction that upcuts the material when the saw is conveyed in the forward direction. The blade guard is mounted to the housing. The blade guard includes a cover surrounding the upper portion of the blade, a shoe surrounding the lower portion of the blade, and an adjustable connection interface between the cover and the shoe. The vacuum collection means is connected to the blade guard.

Abstract: It has been surprisingly discovered that administration of pharmaceutically-acceptable salts of nitrite is useful in the regulation of the cardiovascular system. It has also been surprisingly discovered that nitrite is reduced to nitric oxide in vivo, and that the nitric oxide produced thereby is an effective vasodilator. These effects surprisingly occur at nitrite doses that do not produce clinically significant methemoglobinemia. These discoveries now enable methods to prevent and treat conditions associated with the cardiovascular system, for example, high blood pressure, pulmonary hypertension, cerebral vasospasm and tissue ischemia-reperfusion injury. These discoveries also provide methods to increase blood flow to tissues, for example, to tissues in regions of low oxygen tension.

Abstract: A digital IF processing block including a decimation filter having FIR decimation stages provides improved performance over a Hogenauer decimating filter. The filter comprises multiple integrator stages followed by multiple FIR decimating stages. The zeros of the filter are tunable by adjusting the integer coefficients of the FIR stages providing tunability of the cut-off response, as opposed to the fixed sinc response of the Hogenauer filter. As a result, the number of required stages for a particular steepness is reduced, dramatically reducing the amount of digital circuitry required to implement a particular filter design. The improved filter is especially suitable for use in digital IF stages in receivers, and for code-based applications where selectable decimation rate is desired and a fast multiply is not available.

Abstract: A method and system for modulating and detecting high datarate symbol communications provides superior performance in channels having a fixed spectral efficiency. A quadrature amplitude modulation (QAM) constellation and an optimized mapping are employed to encode/detect a communications signal and error correction is provided using high speed forward error correction techniques. A log likelihood detection scheme and/or a novel phase detector may be employed to further enhance performance.

Abstract: The invention relates to an in vitro cell based expression system for overexpressing heterologous pump proteins associated with drug resistance into the membrane of the host cell for drug screening applications.

Abstract: Apparatus for warning of the failure of a sump pump comprising an electrical alarm connected in an electric circuit, a switch for closing the circuit to activate the alarm, and a movable float positioned in the sump for actuating the switch when the water level in the sump reaches a height indicative of sump pump failure.
