Abstract: A method for data processing comprises: S100. if a to-be-sent email needs to be saved cryptographically or sent cryptographically, automatically converting a main body of the mail into an html file, the html file including an attachment link for linking a mail attachment; S200. compressing a filename of the html file and a filename of the mail attachment into a new html filename and a new mail attachment name using a first open source algorithm based on a first password preset between a sender and a recipient, thereby obtaining a renamed html file and a renamed mail attachment; S300. compressing the renamed html and the renamed mail attachment using a second open source algorithm based on a second password preset between the sender and the recipient, thereby obtaining a compressed file; and S400. releasing a memory space and/or a hard disk space occupied by the to-be-sent mail, encrypting the to-be-sent mail and then saving it to a draft box or sending it in a manner in which a mail has a null mail body and the compressed file is used as the mail attachment. In this way, a method and a system for data processing are implemented, which utilize open source algorithms and have a wider applicability.

Abstract: The present disclosure provides an information entry method and a corresponding device. The method comprises: step a): acquiring in real-time motion data from a user companion device; step b): determining whether the device changes from a first motion status to a second motion status based on the motion data; if so, activating a recording module of the device; step c): recording in real-time the user's voice input through the recording module; step d): stopping recording according to a preset voice instruction of stopping recording. The method and device can address a need of information entry in the following scenario: when a user incidentally wants to record some audios during running or trotting, the device may quickly activate its own recording module based on the acquired motion data so as to enter information in an audio manner, without performing a touch operation on the companion device.

Abstract: The present disclosure provides a data clustering method based on K-nearest neighbor, which sorts data points to be clustered in ascending order according to the maximum radiuses of K-nearest neighbors of the data points, that is, according to the density, and perform the first pass across the data points after sorting the data points in ascending order to incorporate the data points that conform to the statistical similarity into the same cluster; then perform the second pass across the data points with smaller cluster density according to the scale required during the clustering to find out all noise points and incorporate non-noise points into the nearest large-density cluster, so as to realize data clustering, which has the benefits of no need to preset the number of clusters and know the probability distribution of the data and convenience to set parameters.

Abstract: A semiconductor laser accelerator includes several laser acceleration units linked in a cascade manner, and a controller configured to control excitation current supplied to the laser acceleration units. Each laser acceleration unit includes electrodes, an active layer, a first waveguide layer defining one acceleration channel, a second waveguide layer, and a reflecting layer. One or two optical gratings are formed on one or two sides of the acceleration channel to serve as an accelerating area. The semiconductor laser accelerator exhibits a higher acceleration gradient and a smaller structure while not requiring a complex external optical system. In addition, an optical field is controlled by external excitation current, the matching control of an electron beam and an optical field phase can be realized, and the problem of a phase slip can be solved by means of cascade expansion.
