Abstract: On embodiment accesses a set of information comprising one or more elements of information relating to a subject matter, wherein the one or more elements of information have been shared among one or more users of a social-networking system; for each element of information, determines a rate of sharing of the element of information among the one or more users and identifies one or more first users who cause the rate of sharing of the element of information to increase; and identifies one or more influencers associated with the subject matter from the one or more first users identified for each element of information.

Abstract: A robot includes a chassis, a motive subsystem configured to maneuver the chassis, a hopping actuator attached to the chassis and configured to launch the robot, and at least one leg pivotable with respect to the chassis to pitch the chassis upward at a selected launch trajectory angle. A control subsystem automatically actuates and controls the motive subsystem when the robot is airborne and uses the rotational momentum of the motive subsystem to control the attitude of the robot chassis in flight.

Abstract: A furniture assembly system and method useful for assembling furniture provided in disassembled pieces. The system and method can securely and permanently connect two or more pieces of furniture with a furniture element connector without the use of separate tools. The furniture element connector can remain with the furniture while the furniture is in use.

Abstract: One embodiment accesses one or more experts and one or more influencers identified for a subject matter, wherein the one or more experts and the one or more influencers are among one or more users of a social-networking system; and invites a first expert and a second expert to establish a first social connection within the social-networking system.

Abstract: This invention relates to methods to screen for, identify, select and synthesise amphiphilic mitochondrially targeted antioxidant compounds, and compositions, dosage forms and methods reliant on said compounds. The exemplified compounds are all mitoquinone derivatives, being methoxyphenyl alkyl triphenylphosphonium or methoxy dioxocyclohexadiene alkyl triphenylphosphonium derivatives. The compounds, compositions, dosage forms and methods are useful in, for example, the treatment of diseases or conditions associated with oxidative stress.

Abstract: The invention relates to novel NO donors which are targeted to the mitochondria. The NO donor compounds of the invention allow NO to be selectively provided to the mitochondria.

Abstract: Compositions and methods are for disclosed for treating a skin condition that results from reactive oxygen species production in skin of a subject, including applying a topical formulation that contains a lipophilic cation-mitochondrially targeted antioxidant compound and that delivers a therapeutically effective amount of the antioxidant compound to skin fibroblasts and keratinocytes.

Abstract: The invention relates to novel NO donors which are targeted to the mitochondria. The NO donor compounds of the invention allow NO to be selectively provided to the mitochondria.

Abstract: The invention provides a triphenylphosphonium peptide nucleic acid conjugate. The conjugate comprises a peptide nucleic acid linked via a disulfide bond, to a triphenylphosphonium group. Conjugates of the invention can be used to deliver PNA oligomers across the plasma membrane into cells.

Abstract: The methods of preparing quinols and quinones typified by mitoquinol and mitoquinone where a compound typified by idebenone is reacted with Ph3PHX and Ph3P, where X is a halogen atom.
