Abstract: Provided herein are cardiac information processing systems comprising multiple subsystems for performing a procedure and producing procedure data, and a processing module. The multiple subsystems comprise: a mapping subsystem comprising at least one mapping catheter; an imaging subsystem comprising at least one imaging device; and a treatment subsystem comprising at least one treatment device. The processing module receives the procedure data, the processing module comprising at least one processor and at least one algorithm. The at least one algorithm is configured to perform an assessment of the procedure data and produce evaluation data based on the assessment. Methods of processing cardiac information are also provided.

Abstract: An additive compound comprising a derivative of particular fatty acids and polyamines has been found to be friction reducing, and particularly readily miscible in fuels and lubricants. The fatty acid has more than 12 carbon atoms and at least one carboxylic group. The polyamine residue has more than two nitrogen atoms. The mole ratio of the carboxylic groups to nitrogen atoms used to form the compound is greater than 0.8 carboxylic groups per 1 nitrogen atom.

Abstract: A gasoline composition comprising, as an additive, one or more quaternary ammonium salt(s) (i) formed by the reaction of a compound of formula (A): and a compound formed by the reaction of a hydrocarbyl-substituted acylating agent and an amine of formula (B1) or (B2): wherein R is an optionally substituted alkyl, alkenyl, aryl or alkylaryl group; R1 is an alkyl, aryl or alkylaryl group having up to 36 carbon atoms; R2 and R3 are the same or different alkyl groups having from 1 to 36 carbon atoms; X is an alkylene group having from 1 to 20 carbon atoms; n is from 0 to 20; m is from 1 to 5; and R4 is hydrogen or a C1 to C36 alkyl group.
