Abstract: This disclosure provides an access request processing method, a storage device, and a storage system. In embodiments of this disclosure, a first storage device receives an artificial intelligence (AI) model from a second storage device, wherein the AI model is obtained by the second storage device through training based on historical input output (IO) requests in historical running processes. The first storage device obtains a prediction result of the AI model based on an access request received by the first storage device.

Abstract: Disclosed is a method of synthesizing 1,2,4-triazole-3-thione compounds and intermediates thereof. The method includes reacting a hydrazine with glyoxylic acid to form a hydrazono acetic acid intermediate followed by reacting the latter with thiocyanate to obtain the 1,2,4-triazole-3-thione compound. The raw materials involved in the present method are readily available, and the reaction is very specific in terms of regioselectivity, resulting in minimum by-product and high product yield. There are neither specific requirements for special equipment nor special operations such as high vacuum, high temperature, anhydrous and oxygen-free manipulations. The process is simple and generates minimum wastes, suitable for industrial production.

Abstract: It relates to the field of displaying the heart-rate data collected in an exercise test, in particular to a method for achieving a panoramic display during Electrocardiogram Exercise Test by using a time axis, comprising following steps: (a) building a horizontal axis (X axis) in units of time as a time axis, and building a vertical axis (Y axis) in units of heart rate, therefore forming a two-dimensional tendency chart; (b) collecting and storing real-time 12-lead ECG raw data, acquiring and storing real-time heart rate data, (c) setting a time vernier, wherein in a default status, the time vernier is located at the current moment, and it is connected with 12-lead ECG raw data.

Abstract: An ECG measurement approach for any multi-touch screens comprises the following steps: 1) display ECG on the screen; 2) use two fingers to touch the screen and the two touch points have two vertically projected points on the actual ECG waves; 3) draw the horizontal and vertical baselines to show the x interval in milliseconds and y interval in microvolt; 4) move any one or both of the two fingers touch points on the screen, the projected points and the horizontal/vertical baselines updated synchronously, as well as the measurements; 5) measure the different part of the ECG waves using this approach, including the wave top points, wave beginning and ending points. This approach can be used as a measurement tool to any graphs of functions over time displayed on the multi-touch screen, like EEG.

Abstract: A method and system for detecting heart diseases, especially the coronary artery diseases, comprises the steps of obtaining twelve (12) lead cardiac electrical signals from a patient, mathematically transforming the time-domain wave signals into twelve (12) frequency-domain amplitude spectra with one for each of the 12 leads, selecting a number of amplitude readings in the low frequency range of 0 Hz to 25 Hz of the frequency amplitude spectrum density curves for analysis, from a reference clinical database of established diagnostic criterion values selecting diagnostic indexes by which the presence of heart disease is judged, determining the pathological values of diagnostic indexes for each lead, comparing the value of each diagnostic index against the value of said index in the database for detection of heart diseases, compiling and visually displaying all 12 amplitude spectrum density curves with their respective diagnostic indexes in one picture for diagnostic reading thereby accomplishing the detection
