The invention provides an isolated peptide comprising a lactylated lysine and a specific affinity reagent that specifically binds to a lactylated lysine in a peptide. Also provided are a method for detecting a lactylated lysine in a protein or a fragment thereof using the affinity reagent and a method for isolating the affinity reagent.

Reagents and methods for detecting protein lysine lactylation

Display methods and devices are disclosed. An exemplary display method may comprise: displaying a session list page, the session list page comprising a session page entry corresponding to a communication session in which a local end user participates; determining a read/unread status of a sent communication message by the local end user in the communication session; and displaying, in a display area of the session page entry corresponding to the communication session, a status identifier corresponding to the read/unread status.

Display method and device

This disclosure relates to displaying and recognizing two-dimensional codes. In one aspect, a method includes receiving, at a user device, an instruction for displaying a two-dimensional code. The user device obtains multiple two-dimensional codes corresponding to a user. The user device sequentially displays the multiple two-dimensional codes based on one or more predetermined time intervals, so that the multiple two-dimensional codes form a dynamic two-dimensional code on a display page. A ratio of each of the one or more predetermined time intervals to a validity period of each of the multiple two-dimensional codes is less than a predetermined threshold.

Displaying and recognizing two-dimensional code

A method including determining, according to a received type change instruction with respect to a group, a target group type of the group; selecting, according to a limiting condition imposed on group affiliation information of a group member by the target group type, a group member who does not satisfy the limiting condition; and removing the selected group member from the group.

Method for changing group type and group creation method and device

Communication methods and apparatuses are provided. A method may include: obtaining at least a part of a communication message in a communication session page of a communication application, the communication session page being used for conducting communications between an end user and at least one peer user; performing content recognition of the communication message; and configuring a to-be-sent message corresponding to a message sending control in the communication session page, so that the to-be-sent message matches a content recognition result for the communication message. Using the technical solutions of the present disclosure, the efficiency of communications can be improved.

Communication methods and apparatuses

A method may include the following. Preset events related to a peer communication party are determined. The preset events are generated by operations performed by the peer communication party based on a communication application. Whether a communication page of a local communication party with the peer communication party is in an open state is detected. Description information of the preset events is displayed in an expedited processing page associated with the communication page in a centralized manner when the communication page is detected to be in an open state. Using the technical solutions of the present application, the local communication party can open and view the expedited processing page conveniently and quickly when communicating with the peer communication party, and view and process corresponding preset events, thereby further simplifying the user operations and improving processing efficiency.

Method and apparatus for displaying events related to peer communication party to local communication party

The disclosure provides methods and devices for object allocation. In one embodiment, the method comprises receiving, at a server, an object allocation message submitted by an allocation source via a communications application, the object allocation message including an identification of the allocation source, a number of to-be-allocated objects, and an object allocation time; extracting, by the server from an object set corresponding to the allocation source, objects corresponding to the number of to-be-allocated objects; controlling, by the server, acquisition times when the allocation destination will acquire the objects, so that the acquisition times do not happen before the object allocation time.

Methods and devices for controlling the timing of network object allocation in a communications network

Disclosed are systems and methods for acquiring height of a stereo camera, applied to the stereo camera. An example method includes acquiring angle information of a stereo camera, with the angle information including a pitch angle and a tilt angle. A ground image of a scenario where the stereo camera is deployed is captured and depth information of each pixel on the ground image is determined. A three-dimensional point set based on depth information of each pixel on the ground image is established, with the three-dimensional point set including coordinate information of each three-dimensional point corresponding to each pixel of the ground image. Height of the stereo camera is determined based on the angle information and the three-dimensional point set.

Stereo camera and height acquisition method thereof and height acquisition system

Embodiments of application discloses a method and device for determining external parameters of a stereo camera. The method comprises: acquiring ground surface data of a location of the stereo camera; generating, according to three-dimensional coordinates of each pixel in the ground surface data in a camera coordinate system corresponding to the stereo camera, a first plane equation in the camera coordinate system that conforms to the three-dimensional coordinates of the pixels; determining, according to a distance between the origin of the camera coordinate system and the ground surface, a setting height of the stereo camera; and generating, according to the first plane equation, a plane normal vector corresponding to the first plane equation; and determining, according to the plane normal vector, a pitch angle of the stereo camera and an inclination angle of the stereo camera. The external parameters of the stereo camera can be determined without using a reference point in a scene.

Method and device for determining external parameter of stereoscopic camera

Account information, input by a user for data transfer, is received. Identity information associated with the received account information is determined. One or more pieces of account information associated with the determined identity information are determined. The one or more pieces of account information are determined based on a predetermined condition. The one or more pieces of account information include the received account information. The one or more pieces of account information are provided to the user. In response to receiving a user confirmation of the one or more pieces of account information, the data transfer is performed based on the user confirmation.

Accuracy and security of data transfer to an online user account

Embodiments of the present application provide a method and system for private communication. During operation, the system may determine a privacy level from a plurality of privacy levels associated with a private chat function of a communication application. The private chat function may be configured to transmit and receive private chat messages, and each privacy level is associated with visual effects which are different from the visual effects of other privacy levels. The system may obtain mode configuration information corresponding to the selected privacy level. The system may then configure the private chat function for the communication application based on the obtained mode configuration information, and display the visual effects for the communication application according to the selected privacy level.
