  • Publication number: 20210113632
    Abstract: A new use of Lactobacillus paracasei subsp. paracasei K56 capable of regulating the gastrointestinal flora balance is described. The deposit number of the Lactobacillus paracasei subsp. paracasei is DSM27447. This strain alone has the ability to significantly promote the growth of intestinal Bifidobacterium and Lactobacillus, suppress Desulfovibrio and/or Enterobacteria in the intestine, suppress Helicobacter and/or Escherichia-Shigella, and can endure a simulated in vitro gastrointestinal fluid stress environment. Experiments in mice show that this strain has no acute oral toxicity, no antibiotic resistance, and may be safely used in food processing.

  • Patent number: 10685428
    Abstract: Methods and systems which provide super-resolution synthesis based on weighted results from a random forest classifier are described. Embodiments apply a trained random forest classifier to low-resolution patches generated from the low-resolution input image to classify the low-resolution input patches. As each low-resolution patch is fed into the random forest classifier, each decision tree in the random forest classifier “votes” for a particular class for each of the low-resolution patches. Each class is associated with a projection matrix. The projection matrices output by the decision trees are combined by a weighted average to calculate an overall projection matrix corresponding to the random forest classifier output, which is used to calculate a high-resolution patch for each low-resolution patch. The high-resolution patches are combined to generate a synthesized high-resolution image corresponding to the low-resolution input image.

  • Patent number: 10452748
    Abstract: A lack of available responsive options for existing web sites and/or pages, and the wide spectrum under which they fall presents a challenge for a satisfying mobile user experience (UX) with a hosted collaboration service. Templates used to create a site and/or page may each have capabilities and features which “cross-over” into other templates. Deconstructing and rendering a web page into a native application experience at a mobile client may highlight a template's functionality to enhance the UX. For example, a server side application programming interface (API) may be provided for the mobile UX, a type of a page to be rendered may be determined, the page may be deconstructed into pieces, and the deconstructed pieces may be provided to rebuild the page at the mobile client natively. The page may be rendered on the mobile client with added elements based on the deconstructed pieces to enhance the mobile UX.

  • Patent number: 9219924
    Abstract: This invention discloses an encoding apparatus and a decoding apparatus for scalable video coding such that a non-scalable video decoder is usable for decoding a scalable video bit-stream comprising a base layer bit-stream and an enhancement layer bit-stream. In one embodiment, a source video frame is downscaled to give a downscaled video frame, which is then encoded into the base layer bit-stream. The difference between the source video frame and an up-scaled video frame reconstructed from the downscaled video frame in the base layer bit-stream yields a residual frame. The residual frame is partitioned into a number of residual sub-frames each having a resolution that is the downscaled video frame's resolution. The residual sub-frames are encoded into the enhancement layer bit-stream. Thereby, a non-scalable encoder is usable to encode both the downscaled video frame and the residual sub-frames, allowing both bit-streams to be decodable by employing only one non-scalable decoder.
