  • Publication number: 20250107978
    Abstract: A method for skin protection by applying a zinc oxide-on-silicate platelet composite (ZnO/NSP composite) is formulated in a cosmetic composition, to the skin of a subject. The ZnO/NSP composite is made of silicate platelet and ZnO particles adsorbed thereon, in which the ZnO particles are created by the dehydration of Zn(OH)2 formed on the silicate platelet. The ZnO particles adhering on the silicate platelet can effectively improve the dispersibility of zinc oxide particles in water, and the average particle size can reach near nanometer size. Moreover, the ZnO/NSP composite exhibits better antimicrobial and UV light-absorbing properties than ZnO itself, and are not toxic or irritating to the skin.

  • Publication number: 20240267806
    Abstract: Methods and apparatus are provided for UE-triggered handover and early preparation with coexistence of the network-triggered handover. In one novel aspect, the UE is configured early measurement report configuration, receives an early handover command from the serving base station with a handover candidate cell list, monitors handover triggering conditions for each candidate cell on the handover candidate cell list based on a UE-triggered handover configuration and performs the UE-triggered handover to a candidate cell when the corresponding triggering condition is met for the candidate cell. In one embodiment, the UE receives a network-triggered handover command to a target cell, suspends the UE-triggered handover configuration and performs the network-triggered handover to the target cell. The UE discards the UE-triggered handover configuration upon success of the network-triggered handover and resumes the UE-triggered handover configuration upon failure of the network-triggered handover.

  • Publication number: 20240114419
    Abstract: Examples pertaining to secure transmission in mobile communications are described. A UE receives an RRC reconfiguration message from a master network node. The RRC reconfiguration message comprises information regarding candidate cells and predefined reconfigurations, and each candidate cell is associated with one predefined reconfiguration. The UE evaluates a triggering condition for at least one candidate cell to determine whether to trigger a conditional cell change procedure and performs the conditional cell change procedure to switch a PSCell associated with the apparatus to a target cell in an event that the triggering condition for the target cell is met. The UE derives a security key according to a counter value and a key of the master network node. The counter value is obtained from a sequence of distinct counter values of the target cell or of a target secondary node stored by the processor or is generated by the processor.
