Abstract: An online system generates a set of content item variations for a reference content item that include different styles of text for the content item. The different styles of text are generated by applying machine-learned style transfer models, for example, neural network based models to reference text of the reference content item. The text variations retain the textual content of the reference text but are synthesized with different styles. The online system can provide the content item variations to users on an online experimental platform to collect user interaction information that may indicate how users respond to different styles of text. The online system or the content providers can effectively target users with content items that include the style of text the users respond to based on the collected information.

Abstract: The application discloses a preparation method for an aluminum alloy cavity casting filled with special-shaped foamed aluminum. The preparation method includes: preparing special-shaped foamed aluminum in a first mold by adopting a powder metallurgy foaming method; fixing the special-shaped foamed aluminum coated with the soldering flux in a second mold after the special-shaped foamed aluminum is coated with soldering flux; and casting by using molten aluminum alloy. According to the preparation method for the aluminum alloy cavity casting filled with the special-shaped foamed aluminum, the overall strength of the casting can be improved while the wall thickness of the casting is reduced to meet the requirement that the overall quality of the casting is not increased.

Abstract: A fatigue measurement method includes obtaining a face video of a target object, processing the facial video to obtain a plurality of quasi-heart rates and a plurality of quasi-vibration frequencies, selecting a target heart rate from the plurality of quasi-heart rates and a target vibration frequency from the plurality of quasi-vibration frequencies, detecting the target heart rate and the target vibration frequency, and determining, according to the detection result, that the target object is in a fatigue state. The quasi-heart is obtained through one or more of a region of interest (ROI) between eyebrows and an ROI of chin, and the quasi-vibration frequency obtained through one or more of an ROI of eyes and an ROI of mouth.

Abstract: Hydroxamate substituted azaindoline cyanine dyes, conjugates thereof and methods of using the same are provided. The subject cyanine dyes include an azaindoline ring having a hydroxamate substituent. The dyes may further include a reactive group moieties (RGM) and/or a water soluble group. Also provided are conjugates of the subject dyes. Also provided are tandem conjugates including a fluorescent protein capable of energy transfer to the dye. Methods of detecting an analyte in a sample by contacting the sample with a detection reagent are provided. The detection agent may be a dye-conjugate that specifically binds the analyte, or may be a reactive dye which conjugates to the analyte. Also provided are compositions, e.g., kits, etc., incorporating such dyes which facilitate use in such methods.

Abstract: One or more snapshots of data stored over a period of time are maintained in a hybrid storage device comprising a magnetic disk and a solid state disk, wherein a selected snapshot stores information that allows recovery of data that is stored in the hybrid storage device at a selected point in time of the period of time. The hybrid storage device receives an input/output (I/O) command from a computational device. A category of a plurality of categories to which the I/O command belongs is determined, wherein the plurality of categories comprise writing to an unused block, writing to a used block, reading from an unused block, and reading from a used block. In response to determining the category to which the I/O command belongs, the I/O command is handled by one of the magnetic disk and the solid state disk based on the determined category.

Abstract: A sun-tracing sunshade apparatus includes a support, a first top shade member rotatably mounted on the support, a lateral shade member pivotally coupled to the first top shade member, a drive unit installed in the support and adapted for rotating the first top shade member relative to the support, a sun tracker electrically coupled with the drive unit and adapted for sensing the direction of the sun and providing a corresponding signal to the drive unit, and a push member mounted on the support and movable to touch the lateral shade member and to further bias the lateral shade member relative to the first top shade member. Thus, the first top shade member can be turned subject to the direction of sunlight to move the lateral shade member to the optimal shading position, providing excellent sun-shading effect. Further, when the lateral shade member is moved to the front side of the user, it can be lifted by the push member, avoiding hindering the user's sight.

Abstract: A disk player having a self-compensating dynamic balancer so as to subdue internal vibrations due to an eccentric center of mass of a disk, a self-compensating-dynamic-balancer integrated turntable, a self-compensating-dynamic-balancer integrated clamper, and a self-compensating-dynamic-balancer integrated spindle motor which are employed in the disk player. The self-compensating dynamic balancer is embodied by forming a cavity in a turntable, clamper, a rotor of a spindle motor, or the like, and disposing movable members including movable rigid bodies and/or a liquid therein. Internal vibrations due to the eccentric mass of the disk are subdued effectively the movable members moving away from a revolution center according to respective centrifugal forces where the self-compensating dynamic balancer rotates.
