Abstract: Apparatus include divergence optics removably coupled to receive a probe beam in a first imaging mode to cause the probe beam to diverge before impinging on a first area of a target surface, and to not receive the probe beam in a second imaging mode to cause the probe beam to impinge on a second area of the target surface smaller than the first area, collection optics configured to receive, in response to the probe beam, luminescence light emitted from the first area and spectral light emitted from the second area, and an optical detector coupled to the collection optics, wherein the optical detector includes a luminescence imaging detector portion and a spectral imaging detector portion adjacent to the luminescence imaging detector portion, wherein the luminescence imaging detector portion is configured to receive the luminescence light emitted from the first area and the spectral imaging detector portion is configured to receive the spectral light from the second area.

Abstract: The present invention provides 1-aminocyclopropane-1-carboxylic acid synthase (ACC synthase) cDNA sequences from papaya fruit. These sequences are useful in regulation of ethylene biosynthesis in papaya cells and in regulating fruit ripening, including delaying of ripening. This is accomplished by co-suppression or by antisense technology. The present invention also provides methods for regulation of fruit ripening.
Abstract: A color liquid crystal display and display material formed by microdroplets of chiral or cholesteric liquid crystal phase dispersed in a polymeric matrix. The liquid crystal in the microdroplets exhibits strong negative dielectric anisotropy so that in the presence of an electric field the helical planes of the chiral material align perpendicular to the field. Incident light is reflected at a selected wavelength depending upon the helical pitch. In the field-OFF state, the liquid crystal directors are configured or randomly oriented so as to scatter incident light.
