Abstract: In one aspect, the present invention provides a chromatographic stationary phase material for various different modes of chromatography represented by Formula 1: [X](W)a(Q)b(T)c (Formula 1). X can be a high purity chromatographic core composition having a surface comprising a silica core material, metal oxide core material, an inorganic-organic hybrid material or a group of block copolymers thereof. W can be absent and/or can include hydrogen and/or can include a hydroxyl on the surface of X. Q can be a functional group that minimizes retention variation over time (drift) under chromatographic conditions utilizing low water concentrations. T can include one or more hydrophilic, polar, ionizable, and/or charged functional groups that chromatographically interact with the analyte. Additionally, b and c can be positive numbers, with the ratio 0.05?(b/c)?100, and a?0.

Abstract: A social media service and platform generates an improved measure of influence based on measures of purchases of fans made in response to content appearing on an influencer’s channel. The improved influence score addresses the problem that conventional influence scores are often unreliable due to the use of bots and other techniques to artificially increase the number of fans and likes of an influencer’s channel. Additional measures to ensure integrity of channels and support privacy and security may also be supported by the social network service.
