Abstract: A rice-crop intensity identification method based on radar time series observation and temperature analysis is provided. Capturing of diversified periodic characteristics of time series backscatter and detection of backscatter troughs are achieved through time series reconstruction and trough identification; potential phenological phases corresponding to the backscatter troughs are determined through potential rice phenological phase estimation; and through temperature limitation of rice phenological phase, temperature suitability of potential rice phenological phases is evaluated, a backscatter trough that does not satisfy a temperature condition is removed by combining a rice growth mechanism and a regulation of rice-crop intensity, thereby realizing the identification of the rice troughs and the correction of the overestimation of the rice-crop intensity, and finally realizing the identification of rice-crop intensity.

Abstract: Embodiments relate to an automatic detection of fraudulent behavior for a transaction at an online system. The online system requests a large language model (LLM) to determine, based on a prompt input into the LLM, information about a refund event for a first order placed by a user of the online system. The online system accesses a computer model trained to detect a fraudulent behavior associated with an order placed with the online system. The online system applies the computer model to determine a score associated with the refund event, based on the information about the refund event received from the LLM. The online system determines, based on the score, whether the refund event was due to a fraudulent behavior of the user. The online system performs at least one action associated with the online system, based on the determination whether the refund event was due to the fraudulent behavior.

Abstract: Disclosed are a memory operating method, memory and electronic device. The memory complies with a read-write parallel protocol and includes a plurality of memory banks, and the method includes: sequentially mapping read and write transactions for consecutive logical addresses to different banks according to a predetermined transmission bit width by an address decoder, and arbitrating the read transaction and write transaction mapped to the same bank in a current clock cycle by an arbitration circuit, wherein in case that a specific low address bits of the logical address are the same, the read and/or the write transaction are mapped to the same bank. The disclosure avoids long-term occupation of a certain physical bank with specific low address decoding solution, thereby improving the execution efficiency of the read-write parallel protocol. Furthermore, an arbitration mechanism is introduced to arbitrate read and write conflicts for the same memory bank in each clock cycle.

Abstract: An I2C wake-up circuit, method and electronic device are disclosed. The I2C wake-up circuit includes: a clock wake-up circuit, configured to send a clock wake-up signal to a clock circuit in response to detecting a start signal on a serial clock line SCL and a serial data line SDA; and a signal hold circuit, configured to hold the serial data line SDA in a state of not transmitting address information until a clock signal sent by the clock circuit that is wake-up is received. The present I2C wake-up solution can realize normal data reception through a simple hardware circuit without a specific address wake-up and maximize power saving by turning on the clock when there is access and turning off the clock when the access ends.

Abstract: A computer system receives an image from a picker, which indicates an out-of-stock target item and potential replacements items. The system provides, to a machine learning model, a prompt requesting identification of the target item and the potential replacement items in the image. The system receives identification of the target item and a list of potential replacement items in the image. The system generates a first list of potential replacements items based on the list of potential replacement items identified in the image and a second list of replacement items from the target item by applying one or more replacement models to the identified target item. The system may merge the two lists and assign replacement scores to each item in the merged list to create a list of recommended replacement items. The system generates a message based on the image and the list of recommended replacement items.

Abstract: An online concierge system allows users to order items from a warehouse, which may have multiple warehouse locations. The online concierge system provides a user interface to users for ordering the items, with the user interface providing an indication of whether an item is predicted to be available at the warehouse at different times. To predict availability of an item model at different times, the online concierge system selects data from historical information about availability of items at one or more warehouses based on temporal, geospatial, and socioeconomic information about observations of historical availability of items at warehouses. The online concierge system accounts for distances between observations and a time and geographic location in a feature space to select observations for predicting item availability at the time and the geographic location.

Abstract: Disclosed are a memory operating method, memory and electronic device. The memory follows a read-write parallel protocol and includes a plurality of memory banks, and the method comprises: writing data to a specified location of the first memory bank corresponding to a current logical address, and pre-reading original data in a specified location of the second memory bank corresponding to a next logical address in a current clock cycle; encoding the pre-read original data and data to be written next, when an instruction to encode based on the pre-read original data in a next clock cycle is obtained; and writing the encoded data to the specified location of the second memory bank in the next clock cycle. By pre-reading the original data corresponding to the incremental address in the current clock cycle, the present disclosure can accelerate an encoding operation that may occur next.

Abstract: A diffraction analysis device and a method for a full-field X-ray fluorescence imaging analysis are disclosed. The device includes a switching assembly, collimation assemblies, an X-ray source, an X-ray detector, a laser indicator, and a computer control system.
