    Abstract: A vibration frequency adjustment system, comprising a vibratable component (102), at least one counterweight (401, 402), at least one drive device (407, 408), and a controller (307). The vibratable component (102) is configured to be connected to a vibration source (101). The vibration source (101) has an operating frequency range, and the vibratable component (102) has a natural vibration frequency. The at least one counterweight (401, 402) is configured to be movable along the vibratable component (102). The at least one drive device (407, 408) is configured to enable the at least one counterweight (401, 402) to be maintained at or moved to various counterweighting positions (421, 422, 423) on the vibratable component (102). The controller (307) is communicatively connected to the at least one drive device (407, 408).

  • Patent number: 12121510
    Abstract: The present invention generally relates to sensitizer compounds and their use to sensitize cancer and/or pre-cancerous cells of certain cancers to treatment with certain resistance-prone therapeutics used in cancer therapy. In embodiments, the conjugates of particular esters or amides of Near Infrared Dyes, are used as sensitizers to avoid or overcome therapeutic resistance once formed. In embodiments, the sensitizers include conjugates with Cisplatin, Simvastatin, Artemisinin, platin-based compounds or statins. In embodiments, the resistance prone cancer therapeutics include cisplatin, gemcitabine, doxorubicin, paclitaxel, docetaxel, and platin-based compounds. These may be administered in combination with the sensitizer, or the sensitizer itself may comprise an therapeutic-derived moiety conjugated to the sensitizer, for example as is the case for dye-CIS conjugated sensitizers. Alternatively, the sensitizer may be co-administered with one or more therapeutic.

  • Publication number: 20240279148
    Abstract: The present disclosure provides a preparation method of carotenoid agent. The preparation method provided in present disclosure includes: mixing a suspended organic dispersion phase of a carotenoid crystal with a first organic solvent in a spiral coil of a coil heat exchanger to form a mixed solution, with the carotenoid crystal in the suspended organic phase of the carotenoid crystal being dissolved in the first organic solvent to obtain an oil phase matrix of the carotenoid dissolution solution, wherein the temperature inside the spiral coil is from 50° C. to 70° C. In the present disclosure, the carotenoid crystal is dissolved in the first organic solvent at 50° C. to 70° C., effectively avoiding the drawbacks of isomerization reaction of the carotenoid agent when it is dissolved in traditional preparation methods.

  • Publication number: 20230421716
    Abstract: A video processing method and apparatus, an electronic device and a storage medium are provided in the present disclosure. In the video processing method provided in the present disclosure, a target frame image of a target video is fixed in response to a triggering instruction, and a target object in the target frame image is removed, then a padding operation is performed on a target area in the target frame image so as to generate and display a padding frame image. Thus, a special effect that the target object disappears from the target video can be realized, thereby providing visual special effects of more personalized and better visual perception for a user in a video application.
