  • Publication number: 20160127072
    Abstract: Embodiments of the present invention provide a method and an apparatus for increasing and decreasing variable optical channel bandwidth. The method for increasing includes: sending a higher order optical channel data unit (HO ODU) frame to which a timeslot increase indication is added to a second NE; starting from a next HO ODU frame, mapping, by an NE, a bit stream formed by a flexible optical transport data unit (ODUflex) bit stream at a first rate and an idle data bit stream to Y timeslots of the HO ODU frame; sending an ODUflex frame to which a rate increase indication is added to the second NE; and starting from a next ODUflex frame, mapping an ODUflex bit stream at a second rate to the Y timeslots of the HO ODU frame.

  • Publication number: 20150380688
    Abstract: Preparation of semiconductor nanocrystals and their dispersions in solvents and other media is described. The nanocrystals described herein have small (1-10 nm) particle size with minimal aggregation and can be synthesized with high yield. The capping agents on the as-synthesized nanocrystals as well as nanocrystals which have undergone cap exchange reactions result in the formation of stable suspensions in polar and nonpolar solvents which may then result in the formation of high quality nanocomposite films.

  • Patent number: 8784681
    Abstract: Disclosed are soil additives comprised of self-situating, stimuli-responsive polymer compositions and methods of their use. In one embodiment, the polymer composition or polymer network comprises permanent cross-links and non-permanent cross-links, wherein the non-permanent cross-links are capable of being removed upon application or exposure to a stimulus, typically located within the soil. In another embodiment, the method of increasing water retention in soils includes applying a soil additive, comprising polymer networks of the present invention admixed with an aqueous solution to form a colloidal dispersion solution or suspension, to a soil surface. The suspension or colloidal dispersion solution facilitates penetration of the polymer composition through the soil surface and into the soil, migrating typically to lower water potential areas and, more typically, along drainage channels located within the soil.
