  • Patent number: 11963970
    Abstract: The present disclosure discloses a preparation method of ginseng composition with high ginsenoside bioavailability. The composition is composed of ginseng powder of 250 meshes or more and ?-cyclodextrin, and the mass ratio of the ginseng powder to the ?-cyclodextrin is 1:0.05. Results show that when ?-cyclodextrin is used as a solid dispersant and added to the 1000-mesh ginseng powder at a mass ratio of 5%, the total dissolution amount is maximum; and furthermore, animal experiments (SD rats) show that the area under the plasma drug concentration-time curve (AUC0-48 h) after 48 h of ginseng powder ingestion is maximum, indicating that in-vivo bioavailability of the ginseng powder is the highest. The method of this application can effectively inhibit the aggregation of the ultra-finely pulverized 1000-mesh ginseng powder by adding the ?-cyclodextrin, thus significantly improving the total dissolution amount of ginsenoside.

  • Publication number: 20240121035
    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a wireless device may In use non-uniformly distributed bits for amplitude mapping and uniformly distributed bits for sign mapping to support probabilistic constellation shaping (PCS) for transmission of a message. To provide a coding gain with one or more retransmissions of the message, the device may configure redundancy versions based on the non-uniform distribution of one or more symbols. In some examples, the device may include the same set of non-uniformly distributed systematic bits or at least a portion of non-uniformly distributed systematic bits in each redundancy version of the message. Additionally or alternatively, the device may use multiple modulation and coding scheme (MCS) values to modulate one or more of the redundancy versions, where a first MCS value is used to modulate non-uniformly distributed symbols and a second MCS value is used to modulate uniformly distributed symbols.

  • Publication number: 20240106565
    Abstract: Apparatus, methods, and computer-readable media for network coding for handover are disclosed herein. A base station (BS) transmits a first group of encoded packets to a first road side unit (RSU) over a first radio access network (RAN) interface. The BS initiates a handover procedure between the first RSU and a second RSU. The BS receives, from the first RSU, a release acknowledgment associated with the handover procedure and feedback associated with the first group of encoded packets. The BS transmits network coding level information to the second RSU over a second RAN interface based on the feedback. The network coding level information indicates a number of missing encoded packets within the first group of encoded packets for the second RSU to transmit to the UE. The BS transmits, to the UE, a second group of encoded packets associated with the number of missing encoded packets at the second RSU.
