An optical fiber for use in fiber optic sensing of a test sample includes a first core and a second core. The second core is generally coaxially disposed within the first core and is sized smaller than the first core. The second core is capable of delivering pulsed laser energy from the laser for nonlinear optical excitation of the test sample. Nonlinear optical feedback signals can then be collected in both the first core and second core for improved detection efficiency relative to conventional single-mode and multi-mode fibers.

The invention provides liquid electrographic toner compositions comprising a liquid carrier having toner particles dispersed in the liquid carrier. The liquid carrier has a Kauri-Butanol number less than about 30 mL. The toner particles comprise polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions. The toner composition additionally comprises a wax component associated with the toner particle, wherein the wax component and the amphipathic copolymer each comprise at least one of a Lewis acid and a Lewis base pair in an amount sufficient to form weak, reversible intermolecular non-covalent bonds resulting from acid/base interactions between the wax component and the amphipathic copolymer. These toner particles can exhibit excellent final image durability characteristics, and can also provide toner compositions that provide excellent images at low fusion temperatures on a final image receptor.

The invention provides dry electrographic toner compositions comprising toner particles. The toner particles comprise polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions prepared from an organosol reaction process utilizing a liquid carrier reaction medium having a Kauri-Butanol number less than about 30 mL. The S material portion comprises at least one soluble component and at least one non-sorptive component, wherein the non-sorptive component is the reaction product of monomers having an absolute difference in Hildebrand solubility parameter from the liquid carrier of about 3.0 MPa1/2 or greater. Additionally, dry electrographic toner compositions are provided wherein the toner particles comprise polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions. The S material portion of the amphipathic copolymer has an average Hildebrand solubility parameter of from about from about 16 MPa1/2 to about 17.3 MPa1/2, and comprises at least one non-sorptive component having an average Hildebrand solubility parameter that is at least about 0.4 MPa1/2 greater than the average Hildebrand solubility parameter of the S material portion. The resulting dry toner composition can exhibit excellent final image durability characteristics, and can also provide excellent images at low fusion temperatures on a final image receptor.

Dry electrographic toner compositions are provided comprising a plurality of dry toner particles, wherein the toner particles comprise polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions. The dry electrographic toner composition comprises a wax associated with the dry toner particles, wherein a substantial portion of the wax is entrained in the toner particle and a substantial portion of the wax is associated with the toner particle at the surface thereof. Methods of making electrographic toner compositions are also provided comprising preparing polymeric binder particles comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions, and milling the particles before or after formulation as toner particles with wax in the liquid carrier prior to drying to form the dry toner composition. These toner compositions provide images having excellent durability and erasure resistance properties at low fusion temperatures and with little undesired offset.

A method of interactive language instruction includes obtaining a sequence of basic units to present to a student. The method also includes obtaining a plurality of alternate representations for each of a plurality of the basic units. The method further includes presenting at least a portion of the sequence of basic units to the student. The method also includes obtaining input from the student during the presenting of the basic units. For at least one of the sequence of basic units to be presented to the student and the input from the student, segmentation is performed to break up a continuous stream of units into a sequence of discrete units. For at least one particular basic unit with the plurality of alternate representations, at least one of the alternate representations is automatically selected to present to the student based at least in part on the input obtained from the student during the presentation of basic units that are earlier in the sequence of basic units than the particular basic unit.

Various embodiments provide an electrosurgical instrument with a disposable electrosurgical cartridge. In one embodiment, the cartridge has first and second energy-delivery surfaces that carry first and second opposing polarity conductors coupled to a voltage source, together with first and second temperature-responsive variable impedance bodies exposed partly in the respective-delivery surfaces. The cartridge further carries a slidable blade member. The temperature-responsive variable impedance bodies are coupled to the voltage source by series and parallel circuitry. In use, the variable impedance bodies are adapted to modulate current flow and ohmic heating in engaged tissue by providing controlled current paths in the tissue and through the variable impedance bodies as the temperature-responsive bodies sense the temperature of adjacent engaged tissue. The engagement surfaces are capable of highly localized modulation of Rf energy application to engaged tissue to provide high and low temperatures, voltage and current in the tissue to create high strength welds.
