Abstract: A method of separating metallic semiconducting carbon nanotubes includes providing a source of a mixture of semiconducting and metallic carbon nanotubes in a carrier liquid with one of the semiconducting and metallic carbon nanotubes being functionalized to carry a charge. The mixture is pressurized to cause a liquid jet of the mixture to be emitted through a nozzle. A drop formation mechanism modulates the liquid jet to form from the jet first and second drops traveling along a path. An electric field modulating device, positioned relative to the jet, produces first and second electric fields. A deflection device applies the first electric field as the first drop is formed to concentrate the functionalized carbon nanotubes in the first drop and applies the second electric field as the second drop is formed. The deflection device causes the first or second drop to begin traveling along another path.

Abstract: A relational event history is determined based on a data set, the relational event history. Data is populated in a probability model based on the relational event history, where the probability model is formulated as a series of conditional probabilities that correspond to a set of sequential decisions by an actor for each relational event, where the set of sequential decisions includes at least two decisions as to recipients of a relational event, where the probability model includes one or more statistical parameters and corresponding statistics that relate to one or more of senders, modes, topics, or recipients of relational events. A baseline communications behavior for the relational event history is determined based on the populated probability model, the baseline including a first set of values for the one or more statistical parameters, and departures within the relational event history from the baseline communications behavior are determined.

Abstract: An apparatus and method of ejecting liquid drops includes modulating a liquid jet to cause it to break off into drop clusters, including first and second drops traveling along a path, separated on average by a drop cluster period. An input image data independent charging waveform of a charging device includes a period that is equal to the cluster period and first and second voltage states having opposing polarities.
