Abstract: The present disclosure provides an information processing method and apparatus, a terminal, and a storage medium. The information processing method comprises: according to an information read request of a client, determining a user identity corresponding to the client, first data information requested to be read, and a read permission corresponding to the user identity; generating adjusted first data information on the basis of the user identity, the first data information, and the read permission; and sending the adjusted first data information to the client. The column data information in the present disclosure is allowed to be adjusted on the basis of the read permission, and compared with a solution that a permission can only be set for the row data information, the security of the data information is better improved.

Abstract: An updating method of a citation document, an apparatus, an electronic device and a storage medium.

Abstract: Disclosed herein are systems and methods for purifying aqueous solutions. For example, disclosed herein are flexible membrane distillation systems comprising one or more stages stacked on top of each other, wherein each stage comprises: a feedwater layer; a membrane distillation layer; a distillate layer; and a thermally conductive layer. The systems further comprise substantially impermeable top surface, bottom surface, and perimeter. Each feedwater layer is independently receives a portion of a contaminated aqueous solution (a feed solution). Each feedwater layer further receives heat from a heat source to distill at least a portion of the feed solution through the membrane distillation layer, thereby producing a distillate in the distillate layer. Distilling said portion of the feed solution through the membrane distillation layer purifies said portion of the feed solution to produce a purified aqueous solution, which is condensed in the distillate layer to form a condensate.

Abstract: Disclosed herein are composite membranes comprising an omniphobic substrate having a reentrant structure. The omniphobic substrate comprises a plurality of pores, the plurality of pores forming the reentrant structure. The omniphobic substrate further comprises a surface, the surface being coated with a dual functional layer that is hydrophilic in air and oleophobic under water, such that the composite membrane has a top portion and a bottom portion, the top portion comprising the coated surface of the omniphobic substrate, such that the top portion of the composite membrane is hydrophilic in air and oleophobic under water and the bottom portion of the composite membrane is omniphobic. The composite membrane can be antiwetting and/or antifouling in the presence of a hydrophobic contaminant, an amphiphilic contaminant, or a combination thereof. The composite membranes can be used for membrane distillation of a contaminated brine solution.

Abstract: An order processing system includes a computing device, which includes a processor and a storage device storing computer executable code. The computer executable code, when executed at the processor, is configured to: receive an order, determine a cool-down period of the order based on a cost function, and dispatch the order to a warehouse platform when the cool-down period expires. The cost function takes into account at least a waste cost due to process by the warehouse platform according to the order in case of possible cancellation of the order after the cool-down period and a delay cost due to delayed dispatching of the order to the warehouse platform by the cool-down period. The cool-down period is determined as one that minimizes the cost function in a prescribed range.
