Abstract: A multi-lead electrocardiogram (ECG) signal classification method based on self-supervised learning relates to the technical field of ECG signal classification. The method includes: processing an original signal through different data augmentation methods, designing an appropriate encoder module, extracting a feature of an ECG signal through a large amount of easily available unlabeled data such that an encoder learns more class information of the ECG signal, fine-tuning the model encoder with a small amount of labeled data for feature optimization, and continuously optimizing a parameter of a feature extractor by training a model such that a generated feature well reflects a structure and information of input data. Through self-supervised learning, the method reduces obstacles caused by performing ECG signal classification through a large amount of expensive manually labeled data, improving the generalization ability of the model.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may perform, on a set of information bits, a distribution matching procedure to obtain a distributed amplitude symbol sequence. In some cases, the wireless device may perform the distribution matching procedure using approximations of quantities of distributed amplitude symbol sequences that each have a same length and a same transmission energy. The wireless device may then encode the distributed amplitude symbol sequence and transmit the encoded distributed amplitude sequence. A device that receives the encoded distributed amplitude sequence may perform a distribution dematching procedure on the distributed amplitude sequence based on approximating quantities of distributed amplitude symbol sequences.

Abstract: A modified tunnel oxide layer and a preparation method, a TOPCon structure and a preparation method, and a solar cell are provided. The modified tunnel oxide layer is SiOx subjected to plasma surface treatment, and a Si4+ content in the SiOx is greater than or equal to above 18%. The density of the interface state subjected to plasma surface treatment decreases, and compared with the silicon oxide layer prepared in the prior arts, boron has a low diffusion rate in the modified silicon oxide layer and hence the damaging effect of the boron on the tunnel oxide layer is reduced effectively, thereby improving the integrity of the silicon oxide layer and maintaining chemical passivation effect. The modified tunnel oxide layer significantly increases the performance indexes of the TOPCon structure.

Abstract: An operating-system-first error handling system includes an operating system subsystem coupled to a BMC device including a shared memory subsystem, and to a reserved memory subsystem storing error handling information that is configured to direct the storage of error information in the shared memory subsystem in the BMC device. The operating system subsystem identifies a first error and generates first error information for the first error. The operating system subsystem then accesses the error handling information and, based on the error handling information, stores the first error information generated for the first error in the shared memory subsystem included in the BMC device. The operating system subsystem then notifies the BMC device of the first error information stored in the shared memory subsystem. The BMC device may then access the first error information in the shared memory subsystem and transmit the first error information to a computing device management system.

Abstract: The present application provides a hydrophilic and hydrophobic composite packing-based rotating packed bed and a system. A hydrophobic packing and a hydrophilic packing are formed into a composite packing. When said packing cuts liquid, the hydrophobic packing can sufficiently disperse the liquid so as to make the dispersion of the liquid in the packing zone more uniform, and the wettability of the hydrophilic packing allows the liquid to spread sufficiently so as to increase the wetting efficiency of said packing. The phenomenon of droplet aggregation caused to liquid in a single hydrophobic packing zone and the phenomenon of reduction of liquid turbulence caused to liquid in a single hydrophilic packing zone can be avoided. Therefore, applying a hydrophilic and hydrophobic composite packing to a rotating packed bed can further improve the mass transfer and mixing performance thereof.
