Abstract: An online system matches a user across multiple online systems based on image data for the user (e.g., profile photo) regardless whether the image data is from the online system, a different but related online system or a third party system. For example, to match the user across a social networking system and INSTAGRAM™ system, the online system compares the similarity between images of the user from both systems in addition to similarity of textual information in the user profiles on both systems. The similarity of image data and the similarity of textual information associated with the user are used by the online system as indicators of matched user accounts belonging to the same user across both systems. The online system applies models trained using deep learning techniques to match a user across multiple online systems based on the image data and textual information associated with the user.

Abstract: Provided is a method for identifying authenticity and origin of Panax quinquefolius based on terahertz spectroscopy. The time domain spectral information of the Panax quinquefolius sample is obtained, and converted into the frequency domain spectral information by Fourier transform to calculate a terahertz absorption spectrum. The identification is performed by observing whether there are characteristic absorption peaks of pseudoginsenoside F11 in the terahertz absorption spectrum.

Abstract: An open coiled pacemaker lead is provided that has improved structural stability and functional life in vivo. The open coiled lead includes an electrically conductive material that is coated or covered by a thin layer of electrically insulative material. The coated coiled lead has adequate spacing between adjacent coils, and has a lumen of sufficient diameter, to allow for infiltration of biological connective tissue onto the surface of the coated coil when maintained in vivo for a sufficient amount of time. Infiltration of the connective tissue essentially uniformly along the entire coiled lead strengthens and lengthens the functional life of the coated coil lead.
