Abstract: Described are systems and methods that utilize ad campaign acquisition information and user profile data to probabilistically determine which users were acquired through which ad campaign. For example, a user probabilistic attribution score may be determined for each ad campaign for each user, and a user lifetime value may be allocated to different ad campaigns based at least in part on the determined probabilistic attribution scores.

Abstract: An imaging system collects a plurality of images of an extremity of a subject, each collected at a unique spectral band. A physiologic arterial parameter of the extremity is determined from the plurality of images upon image registration. A record of the physiological arterial parameter is recorded in an electronic data store and an indication of the parameter is outputted. The method is performed by a medical professional associated with a temporal clinical expenditure cost in an epoch, for an entity. The product of the (i) epoch and the (ii) temporal clinical expenditure cost is less than a difference between (a) an average or absolute reimbursement associated with the current procedural terminology code by the entity and (b) incidental expenditures associated with the performance of the method.
