Abstract: A system for one-touch split-mode conference access includes a server that transmits a first message associated with a conference with a client. A VOIP device displays a notification based on the first message. The VOIP device transmits a second message to transfer an audio component of the conference to the VOIP device. The audio component of the conference is continued on the VOIP device and the video component of the conference is retained on the client.

Abstract: The present specification discloses video matching. In a computer-implemented method, a plurality of feature vectors of a target video is obtained. A candidate video similar to the target video is retrieved from a video database based on the plurality of feature vectors of the target video. A time domain similarity matrix feature map is constructed between the target video and the candidate video based on the target video and the candidate video. Using the time domain similarity matrix feature map as an input into a deep learning detection model, a video segment matching the target video in the candidate video and a corresponding similarity is output.

Abstract: Applications of iminostilbene in preparing a medicament for treating a cardiovascular disease, specifically, cardiac cerebral ischemia/reperfusion injury. Iminostilbene is capable of reducing three myocardial enzymes and inflammatory factors during ischemia reperfusion and reduces apoptosis during ischemia reperfusion.

Abstract: Input sound spectra are acquired. The input sound spectra include sound spectra corresponding to multiple sound sources. Predicted sound spectra are isolated from the input sound spectra by performing spectrum isolation processing on the input sound spectra. Updated input sound spectra are acquired by removing the predicted sound spectra from the input sound spectra. Next isolated predicted sound spectra continue to be acquired through the updated input sound spectra, until the updated input sound spectra include no sound spectrum.

Abstract: A method for obtaining an optimal reflectivity value for complex multilayer stacks is disclosed. Aspects of the present invention include generating a model of a multilayer stack and parameterizing each layer by a thickness and an index of refraction; allowing a user to input values for the parameters; calculating an extrema for a cost function of reflectivity R using the input parameter values; calculating sensitivity values S for the extrema points; and obtaining an optimal value by calculating a cost function R+S.
