Abstract: The present technology relates to an intelligent road infrastructure system and, more particularly, to systems and methods for a heterogeneous connected automated vehicle highway (CAVH) network in which the road network has various RSU and TCU/TCC coverages and functionalities. The heterogeneous CAVH network facilitates control and operations for vehicles of various automation level and other road users by implementing various levels of coordinated control among CAVH system entities and providing individual road users with detailed customized information and time-sensitive control instructions, and operations and maintenance services.

Abstract: Provided is an automatic air-extracting sealing box cover, comprising a bottom cover and a top cover that are mutually detachably connected, wherein the bottom cover and the bottom cover are connected to form a device chamber, and an automatic air extracting apparatus is mounted in the device chamber; the automatic air-extracting apparatus comprises a power source, a pressure sensor, an air pump, and a controller; the power source is connected to power source input ends of the pressure sensor, the air pump and the controller; an air extracting opening of the air pump and a probe of the pressure sensor project out of a lower surface of the bottom cover; an output end of the pressure sensor is connected to a collection circuit, and an output end of the collection circuit is connected to an input end of the controller; a control signal output end of the controller is connected an on/off control end of the air pump.

Abstract: A wash buffer comprising a surfactant for use in affinity and cation exchange chromatography to purify proteins of interest from protein aggregates and to remove and/or inactivate viruses. When used during affinity or cation exchange chromatography for the purification of a protein of interest, such as an antibody, the wash buffer significantly improves viral clearance from the preparation, while also reducing the levels of host cell proteins and protein aggregates. Following affinity or cation exchange chromatography with the wash buffer, the protein of interest may be further purified using other chromatography and filtration operations.

Abstract: A wash buffer comprising greater than 0 mM and less than about 500 mM arginine, greater than 0 mM and less than about 250 mM guanidine, greater than 0 mM and less than about 250 mM sodium chloride, and greater than 0 mM and less than about 50 mM of an anionic surfactant, or greater than 0% and less than about 0.25% w/v of a non-ionic surfactant. When used during affinity chromatography purification of a protein of interest, such as an antibody, the wash buffer significantly reduces the level of host cell proteins from the preparation. Following affinity chromatography with the wash buffer, the protein of interest may be further purified using membrane chromatography.

Abstract: In some implementations, a computing device can present related points of interest in search results and/or on a map display. For example, the computing device can receive input specifying search parameters. The computing device can obtain search results, including points of interest, associated with the search parameters. The computing device can present the search results such that related points of interest are grouped and/or presented near each other. For example, if a point of interest (e.g., area of interest) corresponds to a geographical area, then the computing device can group the area of interest with other points of interest related to the area of interest. Similarly, when an area of interest is presented on a map display, the geographic area related to the area of interest can be highlighted and related points of interest can be represented on the map display.

Abstract: Techniques for providing a coefficient scaling operational unit to perform the coefficient scaling computation for various image compression schemes are disclosed. To minimize multiple units, each for one image encoding/decoding scheme (e.g., MPEG4 and WMV9), a single coefficient scaling operational unit is designed to accommodate various standards. In one embodiment, the coefficient scaling operational unit comprises an arithmetic logic unit. The arithmetic logic unit operates in accordance with a formula involving multiplication and division. Parameters such as coefficients and quantization parameters are provided to perform the coefficient scaling operation.
