Abstract: A data feature augmentation system and method for a low-precision neural network are provided. The data feature augmentation system includes a first time difference unit. The first time difference unit includes a first sample-and-hold circuit and a subtractor. The first sample-and-hold circuit is used for receiving an input signal and obtaining a first signal according to the input signal. The first signal is related to a first leakage rate of the first sample-and-hold circuit and the first signal is the signal generated by delaying the input signal by one time unit. The subtractor is used for performing subtraction on the input signal and the first signal to obtain a time difference signal. The input signal and the time difference signal are inputted to the low-precision neural network.

Abstract: A method for assessing acute kidney injury of inpatient includes the following steps. An electronic medical record data of an inpatient is captured by a processor, and the electronic medical record data includes a baseline basic serum creatinine concentration data. A target serum creatinine concentration data and a minimum post-admission serum creatinine concentration data of the inpatient are captured by the processor. A dynamic-increasing value of serum creatinine concentration is calculated to obtain by the processor based on the target serum creatinine concentration data, the baseline basic serum creatinine concentration data and the minimum post-admission serum creatinine concentration data. The dynamic-increasing value of serum creatinine concentration is analyzed by the processor to assess whether the inpatient is an inpatient suffering the acute kidney injury or not.

Abstract: A magnetic attraction connection structure includes a main body. The main body has a peripheral edge on which at least one connection surface is defined. The main body is provided with at least one movement space in an interior of the peripheral edge at one side of the connection surface. The movement space is provided with a magnet arranged in an interior thereof. The movement space is of a size that is sufficient to allow the magnet to move in a direction toward the connection surface or to rotate by an angle. In use, the connection surface of the main body is placed in direct contact with another main body at the location corresponding to the magnets, such that the magnets arranged in the two movement spaces automatically move or rotate due to magnetic attraction of opposite magnetic polarities, so as to securely fix the main bodies together.

Abstract: A display stand comprises at least one connecting block having a through hole for accommodating a supporting pole and at least one recess for pivotably connecting with a sloping pole, wherein an isolating element is disposed between the connecting block and the supporting pole within the through hole. The connecting block defines at least one annular groove in the through hole. The isolating element is provided with an annular rib corresponding to the annular groove to enable the isolating element to be snugly fitted in the through hole of the connecting block. The isolating element has an opening to provide a predetermined elastic fore of deformation. Accordingly, when the display stand is unfolded or folded, damages of the connecting block and the supporting pole due to friction therebetween can be eliminated via the isolating element so as to maintain the appearance and increase the service life of the stand.
