Abstract: The present invention discloses a heteroatom- and cycloalkyl-containing organic compound and an organic electroluminescent device containing the compound. The general structural formula of the organic compound is as represented by Formula I. The organic compound has a boron-nitrogen structure with multiple resonance effect, wherein a cycloalkyl-containing fluorenyl structure is introduced on the basis of the boron-nitrogen structure. The molecular size is greatly expanded by means of the cycloalkyl group, thereby effectively avoiding a concentration quenching effect, while the molecular orientation is enhanced due to the planarity of the fluorenyl group.

Abstract: Provided are a text processing method, a model training method, a device, and a storage medium. The text processing method includes: obtaining a source text; inputting the source text into a sequence-to-sequence model, to obtain a target sequence corresponding to the source text; and converting the target sequence into a target table.

Abstract: The invention generally relates to systems and methods that employ a novel wall shear stress (WSS) estimation method for 4D flow MRI. In certain embodiments, the invention provides systems and methods for determining Wall Shear Stress (WSS) with 4D flow Magnetic Resonance Imaging (MRI), that involve receiving 4D MRI flow data; calculating a velocity gradient (and optionally calculating the pressure field) from the 4D MRI flow data; correcting the velocity gradient (such as by using a spatial gradient of the pressure field to correct the velocity gradient), thereby producing a corrected velocity gradient; and determining a WSS from the corrected velocity gradient.

Abstract: Systems and methods for detecting an analyte include test wands configured to employ immunochromatographic assay with new fluorescent labeling technology, a reading device that can specifically identify signals from wands and sync information to the mobile devices. The systems may quantitatively detect progesterone metabolites in urine to track the level changes, confirm ovulation, and/or evaluate menstruation status. The systems and methods assess and track an individual's ovulation cycle by monitoring a hormone pattern of that specific individual, and establishing a dynamic threshold as a baseline for changes in the specific subject's hormones.

Abstract: A flash file system and a data management method thereof are provided, the system including: a creation module, configured to divide a flash memory into a file system region and a flash buffer region; a marking module configured to mark written data as dirty data in a memory buffer when the data are written and an amount of the written data is less than or equal to a preset marking threshold; a synchronization module, configured to merge the dirty data in the memory buffer and write the same into the flash buffer region when data synchronization is required, and notify a backfilling module when the flash buffer region is full; and the backfilling module, configured to read the dirty data in the flash buffer region, write the dirty data into the file system region, and erase the flash buffer region.

Abstract: A manufacturing system for molding a foaming product, includes an upper mold, a lower mold and a heating-and-cooling device, the upper and lower molds respectively having heat transferring channels to permit passage of heat transfer medium from the heating-and-cooling device, wherein at least three types of heat transfer medium with different temperatures flow through the heat transferring channels in the upper and lower molds at three predetermined times with preset flow rates.
