    摘要: A non-invasive tool for skin disease diagnosis would be a useful clinical adjunct. The purpose of this study was to determine whether visible/near-infrared spectroscopy can be used to non-invasively characterize skin diseases. In-vivo visible- and near-infrared spectra (400-2500 nm) of skin neoplasms (actinic keratoses, basal cell carcinomata, banal common acquired melanocytic nevi, dysplastic melanocytic nevi, actinic lentigines and seborrheic keratoses) were collected by placing a fiber optic probe on the skin. Paired t-tests, repeated measures analysis of variance and linear discriminant analysis were used to determine whether significant spectral differences existed and whether spectra could be classified according to lesion type. Paired t-tests showed significant differences (p

    摘要: A method for performing performance prediction with respect to a vertical flight plan. A system performs performance prediction with respect to a vertical flight plan of an aircraft that includes determining which vertical flight plan rules of a plurality of vertical flight rules that have been loaded in a predictions processor are active by monitoring for criteria that are used to initiate or terminate one or more of the vertical flight plan rules. Aircraft state is predicted at waypoints along a lateral flight path in view of active vertical flight plan rules, and the predicted aircraft state is updated within an integrated flight plan database that stores prediction performance data associated with the aircraft's flight.

    摘要: The present invention provides aqueous dispersion compositions comprising one or more than one of each of aqueous dispersions of water-dispersible polymers and aqueous nanocomposite dispersions of at least partially exfoliated layered silicates and water-insoluble polymers to enhance the thermal shock resistance of a waterborne coating, film, or article comprising the composition. Only 2 to 10 phr of the layered silicate, e.g. sodium montmorillonite surprisingly enhances thermal shock resistance. Optional fillers, such as nepheline syenite, may be added. Such compositions may be coated on automotive plastic, TPO or resinous substrates, and provide coatings having a 19 or greater thermal shock resistance according to Ford laboratory test method BI 107-05 when coated on TPO and baked for 15 minutes at from 74 to 90° C. Further, the present invention provides methods of making aqueous nanocomposite dispersions comprising mixing unmodified layered silicate and water insoluble neat resin in water to at least partially exfoliate the clay and subjecting the resulting mixture to high shear.
