Abstract: A method, a system, an apparatus, and a computer program product for determining a location of a wireless device. One or more second wireless devices in a plurality of second wireless devices are configured for processing one or more communications exchanged with a first wireless device in a plurality of first wireless devices to determine a location of the first wireless device in an environment. One or more communications are processed using one or more second wireless devices. The location of the first wireless device in the environment is determined based on the processed one or more communications.

Abstract: Disclosed are antigen binding polypeptides and antigen binding polypeptide complexes (e.g., antibodies and antigen binding fragments thereof) having certain structural and/or functional features. Also disclosed are polynucleotides and vectors encoding such polypeptides and polypeptide complexes; host cells, pharmaceutical compositions and kits containing such polypeptides and polypeptide complexes; and methods of using such polypeptides and polypeptide complexes.

Abstract: Disclosed are an aromatic amine derivative and an organic electroluminescent device including the same. A fluorenyl/silafluorenyl group having an ortho-substituted group is introduced into the structure of the aromatic amine derivative. The aromatic amine derivative may be used as a light-emitting material in a light-emitting layer of an organic electroluminescent device. These novel compounds can provide better device performance.

Abstract: Disclosed are interference simulation system, method and apparatus, interference test system, method and apparatus, and non-transitory computer-readable storage medium. The interference simulation system, provided at a sending end, may include a configuration unit and a simulation unit. The configuration unit is configured to configure interference parameters according to an interference model, where the interference model is generated according to a preset interference scenario. The simulation unit is configured to acquire the interference parameters and generate interference information according to the interference parameters, and further configured to simulate the interference scenario at the sending end according to the interference information.

Abstract: Provided herein are methods and compositions for treating a subject in need thereof comprising administering an effective amount of vesicles with functional transmembrane proteins embedded in the plasma membrane. Also provided herein are methods of restoring gap junctional communication comprising the administration of an effective amount of vesicles.

Abstract: A photomultiplier tube including a photocathode, an electron multiplier, an electron collector, and a power lead, wherein the photocathode and the electron multiplier are disposed in a sealed transparent vacuum envelope, the electron collector and the power lead are connected with an external circuit outside the vacuum envelope, the photocathode is formed on the entire inner surface of the vacuum envelope, and the electron multiplier is located on the internal center of the vacuum envelope to receive photoelectrons from the photocathode in all directions for electrons multiplication. Because the effective photocathode area is increased, the detection efficiency of unit light-receiving area is improved.
