Abstract: Provided are a method and apparatus for determining an audio, an electronic device, and a storage medium. The method includes: a chord corresponding to an input audio is determined in response to receiving the input audio; at least one to-be-selected arrangement style is determined according to the chord and/or a melody attribute of the input audio; at least one to-be-selected arrangement template associated with a target arrangement style is displayed based on a trigger operation to the at least one to-be-selected arrangement style; and a target audio is played based on a trigger operation to the at least one to-be-selected arrangement template.

Abstract: The electronic device includes a folding apparatus and a flexible display. The folding apparatus is configured to bear the flexible display. An elastic component of the folding apparatus may transfer an elastic force to the flexible display by using a housing of the folding apparatus. A force that is away from a main shaft and that is applied to the flexible display when the electronic device is in a flattened state is greater than a force that is away from the main shaft and that is applied to the flexible display when the electronic device is in a closed state.

Abstract: A terminal control method and apparatus, a terminal, and a storage medium are disclosed. The terminal control method may include: acquiring a first eye action, and generating a first signal after a verification in response to the first eye action matching at least one of preset first eye actions; acquiring a second eye action and generating a second signal after acquiring the first signal; and performing an operation according to the second signal.

Abstract: Provided are a humanized anti-A? monoclonal antibody and use thereof. The humanized anti-A? monoclonal antibody provided can inhibit the polymerization of A? monomers, protect nerve cells from the toxicity of A?, and have a certain effect on improving the cognitive learning and memory ability of Alzheimer's dementia model mice, and can be used for the treatment and diagnosis of diseases and disorders related to amyloidosis, such as Alzheimer's disease.

Abstract: An antenna apparatus includes N (2=<N) transmitting antennas configured to transmit RF signals having Orbital Angular Momentum (OAM) of designated modes, and N receiving antennas configured to make N pairs with the N transmitting antennas, respectively, and to receive the RF signals having OAM of the designated modes transmitted from the corresponding N transmitting antennas within the N pairs.

Abstract: A base station includes a plurality of antenna elements, a grouping module that forms a plurality of groups in which a plurality of mobile stations for which degree of mutual interference among the mobile stations is below a threshold are grouped in an identical group, and a forming module that simultaneously forms a plurality of beams for a plurality of mobile stations that belong to a single group for each group of the plurality of groups by using the plurality of antenna elements.

Abstract: An antenna apparatus includes N (2=<N) transmitting antennas configured to transmit RF signals having Orbital Angular Momentum (OAM) of designated modes, and N receiving antennas configured to make N pairs with the N transmitting antennas, respectively, and to receive the RF signals having OAM of the designated modes transmitted from the corresponding N transmitting antennas within the N pairs.

Abstract: An antenna apparatus includes transmitting elements arranged on a first circle and transmit an electromagnetic wave having OAM, a calibration transmitting element disposed at a center of the first circle and transmits a calibration electromagnetic wave without OAM, at least three calibration receiving elements disposed at regular intervals on a second circle, and a plurality of receiving elements disposed on the second circle or a third circle disposed with the second circle in a concentric fashion, wherein an angle of a central axis of the second circle is adjusted so that phases of the calibration electromagnetic wave received at all of the calibration receiving elements match with each other, and wherein an angle of a central axis of the first circle is adjusted so that phase differences of the electromagnetic wave having OAM received by the two adjacent calibration receiving elements among all of the calibration receiving elements are minimized.
