Abstract: The present disclosure relates to compounds of the formula (I) which are precursor compounds of esters, whereby upon hydrolysis of the precursor compound, an ester compound is released. This ester precursor approach can be useful for applications where controlled release of, for example, ethyl formate, is beneficial.

Abstract: Apparatus and associated methods relate to a system for delivering interactive relationship skills training with multiple feedback source types for the benefit of remote players who access the system via electronic communication networks. In an illustrative example, some systems may deliver relationship skills training content having restricted access to two or more types of feedback sources. Feedback sources that may be accessed at first, second, third and fourth tiers may respectively include, for example, predetermined expert responses, a virtual partner, a remote human partner, and a moderated group of remote players. Players may gain access to feedback sources at progressively higher tiers of psychological complexity by accumulating a sufficient relational skills score at each tier.

Abstract: This invention provides methods, devices and device components for treating biological samples with electromagnetic radiation. The methods, devices and device components of the present invention are capable of providing well characterized, uniform and reproducible net radiant energies and/or radiant powers to biological samples undergoing processing. In addition, the present methods, devices and device components are capable of delivering electromagnetic radiation to biological samples having a distribution of wavelengths selected to provide enhanced pathogen reduction, while minimizing photoinduced damage to components comprising therapeutic and/or reinfusion agents.
