Abstract: The present disclosure belongs to the technical field of biology, and in particular relates to an attenuated strain of African swine fever virus (ASFV) with IPTG-induced deletion of a D1133L gene and use thereof. In the present disclosure, it is firstly found that the D1133L protein of ASFV can inhibit production of IFN-? and downstream cytokines ISG-15 and ISG-56, and can be used as an immunosuppressant with a relatively strong immunosuppressive effect. In addition, the attenuated strain of ASFV with IPTG-induced deletion of the D1133L gene is constructed. Specifically, a screening expression cassette is inserted into a position before the non-structural protein gene D1133L of the ASFV using an Escherichia coli lac operator-repressor system, to obtain a recombinant virus. In the presence of the IPTG, the recombinant virus has similar characteristics to a wild-type virus; and in the absence of the IPTG, the expression of the D1133L protein is inhibited.

Abstract: Systems and methods for generating training data using synthesized input images for training a machine learning model for image enhancement in accordance with embodiments of the invention are described. The system may access a target image (e.g., captured by an imaging device), and generate an input image that corresponds to the target image. The input image and target image may then be used (e.g., as part of a training data set) to train the machine learning model. For example, a generated input image corresponding to a target image may represent a version of the target image as if it were captured in low light. The target image may be a target illuminated output to be generated by enhancing the input image. The input image and target image may be used to train a machine learning model to enhance images such as those captured in low light.

Abstract: A job processing method is provided. In this method, after receiving a to-be-processed job, a scheduling node in a high-performance computing system predicts, based on a category of the job, a quantity of resources consumed in real time in a process of executing the job. Because quantities of resources consumed in real time in a process of executing jobs of a same category are close, compared with a specified resource quantity, a predicted resource quantity is closer to a quantity of resources actually consumed by the job.

Abstract: Metal object detection may be performed in a wireless power system by monitoring the 5th or other order harmonic current of a dual-frequency power transmitter driven by a voltage-fed inverter with square-wave output. While power transfer is maintained by tuning at the fundamental frequency, the transmitter circuit is tuned simultaneously at the 5th order frequency or other harmonic frequencies to increase or decrease the flow of the harmonic current for when a metal object is present. The receiver circuit may include a notch filter to filter out the 5th order frequency. With the dual-frequency tuning configuration, the presence of a metal object causes a significant drop of the increase in the harmonic current at the transmitter side while the receiver behaves as an open circuit with no effect on power transfer. The harmonic tuning circuit may be switched off as necessary to leave only the fundamental frequency for power transfer.

Abstract: A best available video stream is determined for each of multiple conference participants within a conference room including multiple cameras based on scores determined for video streams obtained from the cameras. The scores are determined based on representations of the conference participants within the video streams, for example, based on percentages of conference participant faces visible within the video streams, directions of conference participant faces relative to the cameras, directions of eye gaze of the conference participants relative to the cameras, and/or degrees to which conference participant faces are obscured within the video streams. The best available video streams are output for rendering within separate user interface tiles of conferencing software.
