Abstract: A method of switching content, apparatus, device and storage medium are provided. When the user wants to switch the display interface from the first functional interface to the second functional interface, the first switching operation may be triggered. After the first switching operation is acquired, the first display content may be determined according to the content historically displayed by the second functional interface, and the first display content is displayed at the display interface.

Abstract: The present disclosure provides an information processing method, an apparatus, an electronic device, and a storage medium. By establishing a session group including a first identity user and a second identity user in response to the first identity user satisfying a preset first condition, pushing a first session message for the first identity user within the session group according to a preset process node, and displaying a first information editing interface for the first identity user, in response to a first preset operation of the first identity user for the first session message, the present disclosure can achieve automatic group creation, automatic reminder through group session, and entry into a relevant information editing interface through group session, thereby achieving efficient distribution and processing of information.

Abstract: A computer, including a processor and a memory, the memory including instructions to be executed by the processor to calibrate utility functions that determine optimal vehicle actions based on an approximate Nash equilibrium solution for multiple agents by determining a difference between model-predicted future states for the multiple agents to observed states for the multiple agents. The instructions can include further instructions to determine a vehicle path for a vehicle based on the optimal vehicle actions.

Abstract: A temperature-resistant calcium-resistant water-based drilling fluid for oil and gas reservoir protection and a use thereof is provided. The water-based drilling fluid contains a filtrate reducer and a plugging agent, wherein the filtrate reducer is a copolymer that contains structural units represented by formula (1), structural units represented by formula (2), and structural units represented by formula (3), wherein, the mass ratio of the structural units represented by formula (1) to the structural units represented by formula (2) to the structural units represented by formula (3) is (0.1-0.2):1:(0.05-0.1), and the number-average molecular weight of the copolymer is 10,000-100,000, the plugging agent is acrylamide-diallyldimethylammonium chloride copolymer modified graphene.

Abstract: Methods, systems, and computer readable media for lock-free communications processing at a network node are disclosed. One method occurs at a first network node configured to add messages to a plurality of queues, wherein each of the plurality of queues is accessed by one of a plurality of threads. The method comprises receiving a first message associated with a first mobile subscriber; determining that the first message is associated with a first partition key; assigning, based on the first partition key, the first message to a first queue of the plurality of queues, wherein the first queue includes messages associated with the first mobile subscriber and wherein the first queue is accessible by a first thread of the plurality of threads; and processing, by the first thread, messages of the first queue in a first in, first out order.
