Abstract: Aspects of the invention are directed to oral care compositions. In accordance with an aspect, provided is an oral care composition having a surfactant system comprising at least one of: (i) a non-sulfate based anionic surfactant and an amphoteric surfactant, or (ii) a nonionic surfactant and an amino acid surfactant; a stannous ion source; a nitrate ion source; and a phosphate source.

Abstract: Described herein are oral care compositions having a surfactant system comprising four or more surfactants individually selected from a non-sulfate based anionic surfactant, an amphoteric surfactant, a nonionic surfactant, and an amino acid surfactant; a stannous ion source; a nitrate ion source; and a phosphate source. Methods of making and using these compositions are also described.

Abstract: In one aspect, a device for generating triplet photons is disclosed, which includes a waveguide extending from a proximal end for receiving pump radiation to a distal end through which triplet photons generated via nonlinear interaction of the pump radiation with the waveguide exit the waveguide, where the waveguide is configured such that the triplet photons generated within the waveguide reach its distal end at a rate in a range of about 0.05 triplet photons/second/mW and 0.3 triplet photons/second/mW, e.g., in a range of about 0.1 triplet photons/second/mW to about 0.2 triplet photons/second/mW.

Abstract: The present teachings are generally directed to devices and methods for triplet photons generations, and in particular to on-chip integrated sources for generating direct triplet entangled photons.

Abstract: Techniques are disclosed for sharing image data in a collaborative environment. In a network based server situated in an Internet Protocol (IP) based packet data network, a request may be received for a session ID from an image capture requesting device via a networked connection. The network based server may return a session ID to the image capture requesting device. The network based server may then receive image data indicative of a whiteboard and including marked corners. The image data may further comprise metadata including the session ID. The network based server may then process the received image, the processing including a rasterization process and a vectorization process. The network based server may then create a snapshot comprising the received image data, the rasterized image data, the vectorized image data, and the metadata.
