    摘要： A method of determining noise in an audio stream, the method comprising: acquiring a plurality of consecutive time frames of the audio stream each comprising samples of the audio stream; generating a discrete frequency spectrum for each frame responsive to the frame samples; partitioning the frequency spectrum of each frame into a plurality of same frequency bands; determining an audio energy for each frequency band in each frame; and determining an estimate of noise energy for each frequency band in a temporally last time frame responsive to a relatively small number of smallest values for the audio energy in the frequency band of the plurality of time frames.

    摘要： The present invention refers to an apparatus and method of collecting moisture and/or trichomes from fresh tea leaves or other fresh produces in general. It is a technique in tea manufacturing technology field, for assembling the ingredients rich of nutrient but ignored as waste, eliminating dust and enhancing the quality of finished product. A hood, a fluid container, and a pipe with proper length and shape work as a housing for trichome(s) and moisture to be either not filtered or filtered, chilled, condensed, and collected. An air pressure gradient is generated by an air suction/blowing device inscribed into a general tubular-shaped housing to inhale moisture and trichomes through the hood. If desired, one or more filters with suitable mesh size(s) can be installed at suitable location(s) along the housing for preventing clotting and collecting trichomes. A chilling device is installed in a suitable location in the housing for condensing moisture into fluid to be collected by a fluid container.

    摘要： An economic, direct synthetic method for producing water soluble ZnS QDs that are ready for bioconjugation is provided. The method can produce aqueous ZnS QDs with emission wavelengths varying from 400 nm to 700 nm. Highly luminescent metal sulfide (MS) QDs are produced via an aqueous synthesis route. MS QDs are capped with thiol-containing charged molecules in a single step. The resultant MS QDs exhibit the distinctive excitonic photoluminescence desired of QDs and can be fabricated to avoid undesirable broadband emissions at higher wavelengths. The aqueous ZnS QDs are stable in biological fluids over a long period of time. In addition, non-toxic ZnS QDs have been produced with good photoluminescence properties.
