Abstract: This specification discloses example distributed table lock application methods and apparatuses, storage media, and electronic devices. In an example method, a master node receives a data processing request and determines a data table that to-be-processed data corresponding to the data processing request are located in. The master node generates a table lock for the data table; performs a lock operation on the data table and generates lock status information corresponding to the data table; writes the lock status information into a local log of the master node and synchronizes the log to a slave node such that the slave node stores the log. After the master node restarts, determines whether the master node stores the log; and in response to that the master node stores the log, restores the lock operation on the data table based on the lock status information recorded in the log.

Abstract: A method for obtaining a quantity of resource elements in a communication process, comprising: determines a downlink control information format of downlink control information, obtains, based on the downlink control information format, a quantity of resource elements occupied by a demodulation reference signal (DMRS); and determines a size of transport block (TBS) based on the quantity of resource elements occupied by the DMRS.

Abstract: A computer-implemented method, system and computer program product for detecting Unicode injection in text. A language model is trained to determine if text data (e.g., text fragment) conforms with human writing habits using negative and positive samples. Negative samples include samples of text that are not classified as being suspect for containing Unicode characters. Such negative samples include text written by humans. Positive samples include samples of text that are to be classified as being suspect for containing Unicode characters. Such positive samples may be formed by randomly inserting Unicode characters into the corpus of negative samples. After training the language model, the language model is able to determine whether the received text data (e.g., text fragment) is suspect for containing Unicode characters based on whether the text data conforms with human writing habits.

Abstract: A permanent magnet electrodynamic suspension system includes a conductor track and a suspension and guidance device. The conductor track is disposed on a roadbed, and the suspension and guidance device is disposed above the conductor track. The suspension and guidance device includes a first permanent magnet array and a second permanent magnet array. The first permanent magnet array and the second permanent magnet array are the same in the magnetization direction arrangement. The first permanent magnet array and the second permanent magnet array are arranged perpendicular to each other. A guidance method for the permanent magnet electrodynamic suspension system is further provided.

Abstract: A neural architecture search (NAS) system generates a machine-trained model that satisfies specified real-time latency objectives by selecting among a collection of layer-wise sparse candidate models. In operation, the NAS system selects a parent model from among the candidate models. The NAS system then identifies a particular layer of the parent model, and then determines how the layer is to be mutated, to yield a child model. The NAS system calculates a reward score for the child model based on its latency and accuracy. The NAS system then uses reinforcement learning to update the trainable logic used to perform the mutating based on the reward score. The NAS system repeats the above process a plurality of times. An online application system can use the machine-trained model eventually produced by the NAS system to deliver real-time responses to user queries.

Abstract: Methods and systems are disclosed for controlling device movement based on a movement command. Issues on accurately controlling movement of a device such as a programmable robot and rover are addressed by first determining a command type of the movement command, followed by determining specific types of controllers for a high-level controller and a low-level controller based on the determined command type. When the command type is a linear movement, a Proportional-Integral-Derivative (PID) controller is used at the high-level controller and a Proportional/Proportional-Integral (PPI) controller is used at the low-level controller to accurately control a target distance. When the command type is an angular movement, the PPI controller is used at the high-level controller and the PID controller is used at the low-level controller to accurate control the end-heading of the device.
