The present invention relates to novel methods and systems for determining the interaction of molecules using the phenomena of Taylor-Aris dispersion present in fluid flow in conduits. User-submitted data are received and referenced upon receiving a query request from an unregistered requester, a potential response is automatically identified from the user-submitted data, the potential response is extracted, and presented in response to the query request. The method also includes generating a request for content, receiving an electronic file in response to the request, and evaluating the electronic file to recognize a match between at least one portion of the electronic file and the data pattern. The AFM layer is exchange coupled with the bias layer on the same side of the bias layer that contacts the spacer layer. Upon holding the lens, therefore, a face other than the optical surface is provided on the lens so that the lens is held by applying a force to the face from element holding members. If the cardiologist decides that the requested emergency treatment or procedure should be performed, the system accesses the schedules of all associated catheterization labs across multiple hospitals to identify a lab having optimum time-to-treatment.
