  • Patent number: 11542814
    Abstract: A combined telemetry system that can be used while drilling a wellbore consists of a multi-hop telemetry method and a single-hop telemetry method combined in parallel. The multi-hop and single-hop methods can be operated in parallel, for example, so that each telemetry method caries data concurrently from the Measuring-While-Drilling tool located in the Bottom-Hole-Assembly. The multi-hop and single-hop methods can also be operated in series, for example, so that data from the Measuring-While-Drilling tool located in the Bottom-Hole-Assembly are first carried with the single-hop telemetry method and then transferred to the multi-hop telemetry method at one or more node(s) close to the surface. Preferably, the multi-hop telemetry method can also carry data from along-string sensors. Another combined telemetry system that can be used while drilling a wellbore consists of two single-hop telemetry methods combined in parallel.

  • Publication number: 20220363763
    Abstract: The present disclosure provides an anti-PD-L1/anti-LAG3 bispecific antibody capable to effectively block the interactions between PD-L1 and its receptor PD-1 and between LAG3 and its ligand (e.g., a MHC class II molecule and FGL1). The bispecific antibody may have high binding affinity to both of a PD-L1 protein (e.g., a human PD-L1 protein) and a LAG3 protein (e.g., a human LAG3 protein). Also provided are antibodies and fragments that have specificity to the PD-L1 or LAG3 protein alone, or antibodies and fragments having additional specificity to one or more other antigens.

  • Publication number: 20220348675
    Abstract: Provided are bispecific and multi-specific antibodies that target both claudin 18.2 (CLDN18.2) and 4-1BB. These antibodies, in the absence of CLDN18.2-expressing cells, can bind to 4-1BB but are unable to activate 4-1BB signaling. In the presence of CLDN18.2-expressing cells, however, these antibodies can trigger CLDN18.2-dependent 4-1BB signaling, leading to potent immune response to the CLDN18.2-expressing tumor cells.

  • Publication number: 20220332924
    Abstract: Cross-linked polymer nanoparticles were designed and synthesized with cyclodextrins as the starting monomer. These nanoparticles display exemplary adsorption properties in terms of capacity and selectivity, which comes from the synthetic design. The nanoparticles are also highly robust for various practical adsorption applications. The new synthetic method of these nanoparticle materials involves the reaction of cyclodextrin monomers through an emulsion polymerization approach. The size of the nanoparticles can be tuned easily.

  • Publication number: 20220277005
    Abstract: According to implementations of the subject matter described herein, a solution for semantic parsing of the natural language query is provided. In this solution, a first natural language query for a first data table is received, where the first natural language query comprises words. A first set of knowledge representations associated with the first data table are obtained and the first set of knowledge representations describe, in a structured manner, knowledge required for understanding a natural language query for the first data table. The first natural language query is converted into a first sequence of symbols. A first computer-executable query corresponding to the first natural language query is generated.
