Abstract: The present invention provides, in part, protein-drug conjugates comprising an anti-fibroblast growth factor receptor 3 (FGFR3) (e.g., human FGFR3) antigen-binding protein (e.g., scFv, Fab) conjugated to a molecular cargo (e.g., polynucleotides, polypeptides, liposomes or lipid nanoparticles) for delivery of the molecular cargo to a targeted tissue (e.g., brain). Methods for treating various diseases or disorders, such as neurological diseases, with the conjugates are provided.

Abstract: A system for transmitting information between downhole components has a first downhole component with a first mating surface and a second downhole component having a second mating surface configured to substantially mate with the first mating surface. The system also has a first transmission element with a first communicating surface and is mounted within a recess in the first mating surface. The first transmission element also has an angled surface. The recess has a side with multiple slopes for interacting with the angled surface, each slope exerting a different spring force on the first transmission element. A second transmission element has a second communicating surface mounted proximate the second mating surface and adapted to communicate with the first communicating surface.
