  • Publication number: 20240146434
    Abstract: Provided are a wireless communication apparatus and a reference signal generating method, wherein inter-cell interference is reduced inside and outside a CoMP set. A CoMP mode setting unit (101) sets whether the terminal (100) thereof is a CoMP terminal or a Non-CoMP terminal. When the terminal (100) is set as a Non-CoMP terminal, the hopping pattern calculating unit (104) calculates a ZC sequence number to be used as the transmission timing, from among all the ZC sequence numbers that can be used within the system. When the terminal (100) is set as a CoMP terminal, the hopping pattern calculating unit (104) calculates a ZC sequence number to be used as the transmission timing, by hopping the ZC sequence numbers to be used within the CoMP set. A ZC sequence generating unit (105) generates a ZC sequence to be used as an SRS, using the calculated ZC sequence number.

  • Publication number: 20210324388
    Abstract: The present invention relates to a vector encoding a wildtype or truncated form of erythropoietin receptor (EpoR) to promote T cell survival and proliferation. Specifically, it exemplifies a bicistronic vector that expresses a truncated EpoR with an anti-CD19-41 BB-003? chimeric antigen receptor (CAR) that has a greater ex vivo expansion than CAR-T cells and demonstrates a significantly higher anti-leukemic activity in vivo. It also describes the method of producing cells expressing said vector and the use of these cells to kill CD19+ tumour cells.

  • Patent number: 10828845
    Abstract: A wire material for an elastic member includes: inner circumferential-side reinforced fibers that are wound in a spiral form; outer circumferential-side reinforced fibers that are provided on an outer circumference of the inner circumferential-side reinforced fibers; and thermosetting resin that is provided in at least a part of the inner circumferential-side reinforced fibers and the outer circumferential-side reinforced fibers and firmly fixes the reinforced fibers with each other. An angle formed by a winding direction of the inner circumferential-side reinforced fibers and a center axis of the winding is 70° to 110°. A winding direction of the outer circumferential-side reinforced fibers with respect to a center axis of the winding is along a direction of a tensile load applied to the wire material for the elastic member in accordance with a load applying torsional stress to the wire material for the elastic member as an externally applied load.

  • Publication number: 20200208702
    Abstract: A wire adapted to an elastic member includes: a core that is made of metal or alloy and is elastically deformable; and an FRP layer configured to cover an outer surface of the core, and including fibers wound around the core, and thermosetting resin provided at least partially to the fibers and fixing the fibers to each other. A winding direction in which the fibers are wound around the core is along a direction of a tensile load out of the tensile load and a compressive load applied to the wire adapted to an elastic member based on a load applied from outside.
