A method and apparatus for efficiently matching a large collection of user profiles against a large volume of data in a webcasting system. The method removes redundant patterns in user profiles and information content to improve matching performance based on a Boolean-based query language. Users can select desired information content by choosing a set of predicates to assert the properties for each cyberspace document desired. Boolean operators of AND, OR and NOT connect predicates together on the information items that will be pushed to them. The method includes dynamic cost/credit adjustment based profile indexing and matching.

The invention relates to a method and a process of determining individual skin structure and function at a point in time for the purpose of determining and formulating skin care products that remedy the deficiencies observed in the skin. Objective and repeatable dermal biometric instrumentation techniques can be used to measure skin moisture content, sebum content, firmness and elasticity properties, skin thickness, transepidermal water loss, skin pH and to perform a photo analysis of the face with UV and visible light. By customizing the skin care products, the individually added active ingredients can be controlled, the diluents can be modified, dermal penetration rates can be controlled, the surfactant systems can be adjusted, and the stability of the product can be controlled. To prevent the loss of active materials in the product, the skin care product is manufactured for an individual consumer and is only sold in a quantity of a three months supply. Additionally, a variety of ingredients can be combined that a mass produced product cannot contain due to stability/compatibility issues. This invention overcomes the limitations in formulating skin products for the mass market by providing a product designed with objective biometric data and created for the specific clinical condition of an individual's skin.

The disclosed embodiments relate to implementation, such as by a message processing system architecture, of a message handling system and/or protocol which mitigates optimistic messaging behavior. As used herein optimistic messaging behavior may at least refer to the transmission, in whole or in part, of a message, or of one or more messages of a sequence thereof, to a receiving system, such as the system implemented by the disclosed embodiments, prior to the sender determining that the message(s) is/are desired, alone or in conjunction with subsequently canceling or otherwise invalidating the message(s) once it has been determined that it is not desired. The disclosed embodiments mitigate such behavior by detecting and taking action with respect to these types of messages to deter optimizing behavior which may or may not be manipulative, while maintaining reliable message handling under increasing processing loads with minimal impact on users being able to send messages to the system.

The invention provides a synergistic surfactant composition comprising: (a) from 5 to 95 wt % of a first surfactant which is selected from derivatives of alkyl polyglucosides and mixtures thereof; and (b) from 5 to 95 wt % of a second surfactant which is selected from: amphoteric surfactants, cationic surfactants, anionic surfactants, non-ionic surfactants, and mixtures thereof. This surfactant composition may be used to generate foam that is used for unloading a liquid from a hydrocarbon reservoir. It may be that the liquid unloading of foam generated using the surfactant composition is greater than that of foam generated from the first and second surfactants when they are foamed individually.
