Abstract: System and methods are described for generating recommendations from dynamically-mapped data. In one implementation, a database system receives a first request to generate a recommendation objection and a second request to retrieve additional data to include in the recommendation object. The database system retrieves the recommendation data from a first database table. The database system identifies the additional data in a second database table that is stored separately from the first database table. The database system generates the recommendation object to include the recommendation data from the first database, and maps the additional data to one or more fields of the recommendation object.

Abstract: The present invention provides a detection device based on the shadow imaging of platelets and a method thereof. The method comprises following steps: optically projecting and/or photographing a blood sample to be detected directly by an image sensor chip having a submicron pixel size and a megapixel scale, the blood sample being injected into a sample chamber of a microfluidic chip fixed to the surface of the image sensor chip; and then, identifying and counting imaging results by an image processing algorithm when the physical pixel size, in the imaging results, occupied by abnormally-sized platelets in the blood sample is significantly greater than the physical pixel size occupied by normally-sized platelets, so as to obtain the number and proportion of the abnormally-sized platelets.

Abstract: An egg cooking system includes two woks and each of the woks receives oil from an oil supply member. A support member is driven by a driving unit to allow one egg to be put in the at least one standby portion and the egg is pressed by the pressing member. A cracking member cracks the egg and the pressing unit moves toward the direction that the egg is located so that a claw is opened, and the egg flows into one of the woks. The egg is cooked for a pre-set time, and is dropped into the other wok to be cooked. The cooked egg is then dropped to a plate. The pressing unit presses the egg shell of the egg to further open the claw, and the egg shell drops into a garbage can.

Abstract: The present technology provide compositions that are drug delivery systems for the sustained release of anti-stenotic drugs for the treatment and prevention of occlusion of blood vessels, particularly after perivascular surgery. The compositions include a hydrogel, unimolecular micelles dispersed within the hydrogel, and an effective amount of anti-stenotic drug dispersed within the unimolecular micelle. The hydrogel may be a di-or tri-block copolymer comprising one block of poly(ethylene glycol) (PEG) and one or two blocks of poly(lactic-co-glycolic acid) (PLGA). The unimolecular micelle may include three domains: a dendritic polymer core, hydrophobic block polymers (e.g., PVL, PVCL, and/or PCL) attached to the core and PEG attached to the hydrophobic block polymers.

Abstract: We have seen that some waveguides exhibit variable and increasing back reflection of single wavelength illumination over time, limiting their effectiveness and reliability. We have developed approaches to improve the transmission of these waveguides. We have found that by modulating the illumination wavelength over a small wavelength range we can reduce or eliminate this back reflection from the waveguide. In addition, we describe the writing and erasing of gratings within SiON waveguides by forming standing waves. Methods, systems, instruments, and devices are described that provide improved transmission of light through such waveguides.

Abstract: A wheeled jumping robot includes a body with two wheels, and a board is connected between the two wheels. A driving unit and a jumping unit are respectively connected on two sides of the board. The jumping unit has two rails, and a tubular member is located between the two rails and connected to a threaded rod. A bridge is connected between two rails. Rollers are located between a threaded portion of the threaded rod and a tapered contact face of the bridge. When the threaded rod is rotated, the rollers move toward a pre-set position, the bridge compresses resilient members on the two rails. When the tubular member moves toward the pre-set position, the rollers are separated from the threaded rod due to the tapered contact face, the resilient members bounce back. The wheeled jumping robot includes a processing unit for being communicated with a remote control unit.
