Abstract: An ultrasonic non-destructive testing method and system for detecting lithium precipitation in lithium-ion batteries are provided. The method includes the following steps: acquiring full matrix capture data of the lithium-ion battery using an ultrasonic phased array transducer; inputting the measured ultrasonic data into the initial fully convolutional network (FCN), which outputs a predicted ultrasonic velocity model; using the predicted model as the initial input for an acoustic wave equation that outputs reconstructed ultrasonic data; constructing a loss function using the deviation between the measured and reconstructed ultrasonic data, and iterating until the loss function converges. This process completes the training of the unsupervised FCN. The trained FCN then outputs an accurate reconstructed ultrasonic velocity model that represents the lithium precipitation in the battery.

Abstract: A method, computer program product, and computer system for dynamically allocating shared memory among multiple execution threads via use of a dynamically changing memory threshold. A trained machine learning model (MLM) is executed to calculate the memory threshold (MTH) using values of one or more input parameters as input to the MLM. After executing the MLM, a request is received from a requesting execution thread for a requested amount (MR) of the shared memory. In response to the request, the shared memory is distributed among one or more current execution threads currently using the shared memory and the requesting execution thread. The redistributing is performed as a function MTH, MR, MU, and MC, wherein MU is a total amount of the shared memory currently being used by the one or more current execution threads, and wherein MC is a memory capacity of the shared memory.

Abstract: A dual-mode sensor structure applied to the detection of breast cancer cells in blood samples is disclosed, along with a method of using the dual-mode sensor to detect magnetic particles coupled with antibodies in blood. The sensor generates a magnetic field by electrification of a wire or coil to attract the magnetic particles to the surface of the sensor.

This improves the linearity and accuracy of the sensor output voltage and detection of the number of magnetic particles. The sensor can detect the number of magnetic particles quickly.

The GAA FET device includes an extension region of semiconductor material coupled from the respective channel to the source/drain region to facilitate forming a conductive channel between the source and the drain regions when the GAA FET device is activated.
