  • Publication number: 20240374441
    Abstract: The present invention relates to a thin, flexible absorbent article which comprises a topsheet, a backsheet, an absorbent core disposed between the topsheet and the backsheet, and an acquisition-distribution system (“ADS”) disposed between the topsheet and the absorbent core. The ADS comprises a first layer comprising a nonwoven. The first layer comprises a first stratum facing towards the topsheet and comprising first absorbing fibers, a second stratum facing towards the backsheet and comprising second absorbing fibers, and a plurality of apertures. A percentage of the second absorbing fibers in the second stratum is at least about 15% higher than a percentage of the first absorbing fibers in the first-stratum as measured according to the Fiber Number Test.

  • Publication number: 20240101590
    Abstract: Provided herein are analogs of unnatural nucleotides bearing predominantly hydrophobic nucleobase analogs that form unnatural base pairs during DNA polymerase-mediated replication of DNA or RNA polymerase-mediated transcription of RNA. In this manner, the unnatural nucleobases can be introduced in a site-specific way into oligonucleotides (single or double stranded DNA or RNA), where they can provide for site-specific cleavage, or can provide a reactive linker than can undergo functionalization with a cargo-bearing reagent by means of reaction with a primary amino group or by means of click chemistry with an alkyne group of the unnatural nucleobase linker.

  • Publication number: 20230356532
    Abstract: An ink cartridge and a printing apparatus using the same. The ink cartridge includes an ink cartridge body, a chip and a chip holder, and the chip is fixed on the chip holder; when the ink cartridge is installed on the printer along an installation direction, the printer may drive the chip holder to linearly move along a top surface of the ink cartridge body, the chip holder is located at a first position before linearly moving and located at a second position after linearly moving; the chip at the first position is closer to the top surface of the ink cartridge body than at the second position, and when the chip holder is at the second position, the chip abuts against the stylus. The ink cartridge and printing apparatus achieve a higher stability of the electrical connection of the chip and the stylus in a printer.

  • Patent number: 11194997
    Abstract: A method and a system for thermal infrared facial recognition are provided. The method includes: determining a thermal infrared facial image to be recognized; inputting the thermal infrared facial image to be recognized into a trained three-sense component extractor to position eyes, a nose, and a mouth of a face in the image, and to perform regional positioning of a left eye, a right eye, the nose, and the mouth, so as to constitute a corresponding key region group; performing affine transformation on the thermal infrared facial image to be recognized using a difference between a key region group of a standard face and the key region group of the face to be recognized; inputting a thermal infrared image after face alignment calibration into a trained facial feature extraction to extract corresponding facial features; and inputting the extracted facial features into a trained classifier to recognize information of an owner.
