Abstract: The present invention provides a method for extracting a neuroimaging biomarker based on an interpretable ensemble three-dimensional convolutional neural network (3DCNN) to address limitations in the prior art. The present invention derives a novel neuroimaging biomarker P-score from prediction results obtained by an ensemble three-dimensional convolutional neural network model. The solution can help researchers to conduct studies on longitudinal trajectory changes of structural magnetic resonance imaging (sMRI) during the progression of Alzheimer's disease, and analyze an association of the longitudinal trajectory changes with neurodegenerative changes of Alzheimer's disease subjects. The extracted neuroimaging biomarker can provide a basis for predicting a sequence of intervention of brain regions in the neurodegenerative changes of Alzheimer's disease patients and upcoming clinical symptoms.

Abstract: The present disclosure relates to a charging and discharging control method and apparatus for an energy storage system, a controller, and an energy storage system. The method includes obtaining set target charging and discharging power; determining actual charging and discharging power on the basis of the target charging and discharging power according to a preset charging and discharging strategy. The preset charging and discharging strategy takes the operating state and operating parameter of the energy storage system as consideration factors; multiplying the actual charging and discharging power by a preset percentage and then sending the actual charging and discharging power to an power conversion system for execution. The preset percentage is greater than zero and less than 100%; and sending, after a preset time, the actual charging and discharging power to the power conversion system for execution.

Abstract: A preparation method of CsDFP for aqueous negative electrode slurry includes carrying out ion exchange reactions with LiPO2F2 and a cesium source. The activation energy of Li+ intercalation in the negative electrode is reduced due to the existence of Cs+, leading to a better rate performance. Further, the impedance growth rate of the batteries is reduced and the high temperature storage performance is excellent since PO2F2— participates in the electrochemical reaction to form a stable low-impedance SEI film on the surface of the negative electrode plate. Moreover, films are continuously formed to repair the SEI films under the gradual release of CsDFP, which is conducive to inhibiting the growth of lithium dendrites during long-term high-rate cycling, thereby obtaining an improved cycle performance.

Abstract: A semiconductor measuring tool has a folding mirror configuration that directs a light beam to pass the same space multiple times to reduce the size and footprint. Furthermore, the folding mirrors may reflect the light beam at less than forty-five degrees; thereby allowing for smaller folding mirrors as compared to the prior art.

The calibration method includes: determining locations of the holes defined in the calibration wafer based on two opposite intensity frame; comparing the locations of the holes against the locations measured utilizing an external measurement device; adjusting a first optical magnification or a second optical magnification at least partially based on the comparison result; defining a distortion map for each of the first and second intensity frames based on the comparison of the locations of the holes; generating an extended distortion map for each of the first and second intensity frames by map fitting the distortion map; and utilizing the extended distortion map for each of the first and second intensity frames to reduce at least one of: a registration error or an optical distortion in a subsequent measurement process.

Abstract: Methods and systems for reducing wafer shape and thickness measurement errors resulted from cavity shape changes are disclosed. Cavity calibration process is performed immediately before the wafer measurement. Calibrating the cavity characteristics every time the method is executed reduces wafer shape and thickness measurement errors resulted from cavity shape changes. Additionally or alternatively, a polynomial fitting process utilizing a polynomial of at least a second order is utilized for cavity tilt estimation. High order cavity shape information generated using high order polynomials takes into consideration cavity shape changes due to temperature variations, stress or the like, effectively increases accuracy of the wafer shape and thickness information computed.

The interferometer system includes two spaced apart reference flats having corresponding reference surfaces forming a cavity therebetween for placement of a polished opaque plate. The surfaces of the plate are approximately 2.5 millimeters or less from the corresponding reference surfaces when the plate is placed in the cavity.

Abstract: A hand-off control method is disclosed that can reduce the rate of occurrence of forced disconnection of communication. The intensity of signals received from a base station is periodically measured in a mobile station, the amount of relative change in received signal intensity is calculated for every measurement interval, and the measurement results and calculation results are notified to the base station and the base station of the hand-off destination. If the mobile station requests hand-off, the call of the mobile station is allocated in the hand-off destination base station to an appropriate queue among a plurality of queues that are given an order of priority, based on the amount of relative change for the call. The call is reallocated to a queue that corresponds to the new amount of relative change whenever the amount of relative change is updated. In addition, the waiting rank of the call within the queue is determined based on the received signal intensity at the mobile station.
