Abstract: A system for and method of regenerating a siloxane treatment vessel. At least one heat exchanger receives a flow of fluid from the siloxane treatment vessel, and discharges a cooled flow. A knockout tank receives the cooled flow, separates a condensed portion for disposal, and discharges the remainder. A heater raises a temperature of the remainder flow of fluid, and delivers a heated flow to the siloxane treatment vessel.

Abstract: Representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve to a deficient valve are disclosed. In one embodiment, for instance, a support structure and an expandable prosthetic valve are delivered to a position on or adjacent to the surface of the outflow side of the aortic valve (the support structure defining a support-structure interior) via a delivery system. The expandable prosthetic valve is delivered into the aortic valve and into the support-structure interior. The expandable, prosthetic heart valve is expanded while the expandable prosthetic heart valve is in the support-structure interior and while the support structure is at the position on or adjacent to the surface of the outflow side of the aortic valve, thereby causing one or more native leaflets of the aortic valve to be frictionally secured between the support structure and the expanded prosthetic heart valve.

Abstract: Provided are methods of treating skin with at least two alternating treatment modalities to improve the health and/or diminish signs of aging. Some methods according to the present invention may comprise topically applying at least two separate compositions, in a sequential, rotating, or alternating fashion to overcome adaptation, tolerance, or sensitization phenomena.

Abstract: The application relates to oral care compositions comprising substantive polyesters formed from xylitol, polycarboxylic acids (or esters, acid halides or anhydrides thereof) and optionally arginine. The formed polyesters or polyesteramides are active in biofilm inhibition and dissolution to maintain clean teeth.

Abstract: The application relates to oral care compositions comprising substantive polyesteramides formed from polyols, polycarboxylic acids (or esters, anhydrides or halides thereof) and arginine. The formed polyesteramides are active in biofilm inhibition, biofilm dissolution and retarding or preventing acid production from oral bacteria.

Abstract: According to one aspect, embodiments of the invention provide a system for restricting access to a network, the system comprising a monitoring module configured to be coupled to a plurality of network access points and to monitor transmissions to the network via a plurality of network security appliances, and a blocking module, wherein the monitoring module is further configured to identify a potential bad actor based on a transmission from the potential bad actor to the network via a first one of the plurality of network access points and a first one of the plurality of network security appliances and provide information related to the potential bad actor to the blocking module, and wherein the blocking module is configured to confirm that the potential bad actor should be blocked and in response, to automatically configure each network security appliance to block the potential bad actor from accessing the network.

Abstract: A medical device configured for placement in a blood vessel, in which an elastic tube extends between first and second expandable anchoring stents. The elastic tube is constructed of a resilient material that deflects outward in response to increased blood pressure of a heart beat and that moves back inward as the blood pressure drops, thereby aiding the heart's pumping action.

Abstract: An online system presents advertisements itself and provides advertisements to third party systems. To mitigate different amounts interactions performed by users presented with advertisements via the online system or presented via a third party system, the online system modifies bid amounts associated with advertisements based on a difference in a number of interactions performed by users presented with advertisements via the online system and a number of interactions performed by users presented with advertisements via a third party system. Based on the difference in interactions performed by users presented with advertisements via the online system and via the third party system, the online system modifies bid amounts associated with advertisements. When the third party system requests an advertisement from the online system, the online system selects an advertisement for the third party system using the modified bid amounts.
