Abstract: A schedule data structure includes a schedule of visits to a plurality of destinations over a plurality of weeks, the visits being associated with respective rider/vehicle identification (RVID) parameters corresponding to one of the plurality of riders/vehicles. The schedule may be optimized for multiple parameters but non-optimized for mirroring. The schedule data structure may be broken into a first part and a second part. A permutation of the first part may be determined and appended with the second part. A mirroring-improved schedule data structure may be determined in response to iterated permutation and appending.

Abstract: In embodiments of the present invention improved capabilities are described for facilitating sharing of user-submitted purchase information with other users of a social network. A purchasing information platform may secure permission from the user to connect to a user account, passively gather user purchasing information from the user account, provide a user-search facility to allow the user to find another user within the social network, allow the user to create a sharing user by selecting another user to share the user purchasing information with, publish the user purchasing information so that it becomes viewable to the sharing user, and allow the user and the sharing user to create commentary on the published user purchasing information. Related user interfaces, application programming interfaces, applications, and systems are disclosed.

Abstract: The present invention relates to the preparation of highly pure donepezil of formula I or salt thereof, by hydrogenating indanonylidenyl compound of formula II, using platinum catalysts.

Abstract: Methods of forming a hydrophilic porous polymeric membrane which include preparing a porous polymeric membrane from a polymer blend which typically contains a hydrophobic non crosslinkable component (e.g. PVdF) and a component which is cross-linkable (for instance, PVP) and treating said porous polymeric membrane under cross linking conditions to produce a modified membrane with greatly improved water permeability and hydrophilic stability. Cross linking condition include chemical (e.g. peroxodisulfate species), thermal or radiation and/or combinations thereof. Non cross linked material may be washed out if desired.
