Abstract: A bridgeless PFC circuit includes: a control module that collects a current flowing through a current sampling element; and when the current flowing through the current sampling element is greater than a first threshold, the control module controls a switch element to be turned on. Based on the current flowing through the current sampling element, the switch element can be controlled to be turned on, thereby implementing zero-voltage turn-on of the switch element. Because the collected current does not change abruptly, a delay requirement on a sampling control circuit included in the control module is lowered, and a signal anti-interference capability of the control module is strong.

Abstract: Channel access in unlicensed spectrum may be a function of the type of physical channel and/or a procedure that initiated a transmission. An LBT procedure may be performed as a function of beam management. A WTRU may access a channel using multiple channel access methods associated with multiple uplink transmissions based on a determination of persistent interference associated with the channel. Channel access methods may be performed with different parameters or characteristics based on the resource type/timing of the transmission/measurements of DL/UL RS. Channel access methods may be characterized by a sensing duration, an ED threshold, a beam width, and/or a beam direction. Different ED thresholds may be applied as a function of one or more characteristics of an applicable beam. Multiple sensing methods and/or related parameters may be applied as a function of the type of physical channel and/or the type of procedure associated with a transmission.

Abstract: A diagnosis system trains a set of machine-learned diagnosis models that are configured to receive an image of a patient and generate predictions on whether the patient has one or more health conditions. In one embodiment, the set of machine-learned models are trained to generate predictions for images that contain two or more underlying health conditions of the patient. In one instance, the symptoms for the two or more health conditions are shown as two or more overlapping skin abnormalities on the patient. By using the architectures of the set of diagnosis models described herein, the diagnosis system can generate more accurate predictions for images that contain overlapping symptoms for two or more health conditions compared to existing systems.

Further, amorphous layers may be inserted into the device structure to reset the growth texture of the device to a (001), (110), or (111) texture in order to promote the growth of tunneling barrier layers or antiferromagnetic (AF) pinning layers.

Abstract: In order to guarantee data validity of data read from a memory device of the data storage device to a host device, a controller of the data storage device may calculate a cyclic redundancy code (CRC) signature of the decoded data and compare the CRC signature of the decoded data with a CRC signature of the data. The CRC signature of the data is generated during a write operation of the data to the memory device. Rather than returning an uncorrectable error correction code error (UECC) error to the host device when the CRC signature of the decoded data does not match the CRC signature of the data, the controller executes the read command again. By using a different buffer to store the decoded data, the controller may confirm whether the error stemmed from the read path or the error was not from the read path.
