  • Publication number: 20200332282
    Abstract: A visual continuous spatial directed evolution method is disclosed. The host grows and moves in a solid culture space, the host carrying a foreign target gene to be evolved and containing a gene element that assists the evolution of the target gene, the target gene being correlated with the growth and movement of the host. Depending on different spatial distribution patterns formed in the solid culture space during the growth and movement of the host, screening is performed to obtain an evolved product. This method is carried out directly in the solid culture space. Depending on images of different spatial distribution morphologies visible to the naked eye that are locally formed, selection of evolved products is performed without the need for liquid fed-batch culture equipment. In addition, the evolution effect is visually observed through the infection spots formed during evolution, so that no real-time monitoring equipment is required.

  • Patent number: 10805928
    Abstract: Communications in a wireless network for carrier Selection and switching are provided. A terminal in the wireless network is simultaneously receiving data on at most m carriers. A base station in the wireless network sends an activation command associated with more than m carriers to the terminal. The terminal activates the more than m carriers. Then the base station selects a first subset from the activated carriers, and sends a first monitoring command associated with the first subset via a first physical-layer signaling to the terminal. When load and/or interference situations are changed, the base station selects a second subset from the activated carriers, and sends a second monitoring command associated with the second subset via a second physical-layer signaling to the terminal, wherein the first subset is different from the second subset.

  • Publication number: 20200322108
    Abstract: User Equipments (UEs) may be assigned a set of aggregated component carriers for downlink carrier aggregation and/or carrier selection. Some UEs may be incapable of transmitting uplink signals over all component carriers in their assigned set of aggregated component carriers. In such scenarios, a UE may need to perform SRS switching in order to transmit SRS symbols over all of the component carriers. Embodiments of this disclosure provide various techniques for facilitating SRS switching. For example, a radio resource control (RRC) message may be used to signal a periodic SRS configuration parameter. As another example, a downlink control indication (DCI) message may be used to signal an aperiodic SRS configuration parameter. Many other examples are also provided.
