Patent CA-2338291-A1 (CA)
Title: Nonlinear vibrational microscopy
Inventor: XIE XIAOLIANG SUNNEY
IPC: G01N21/65
Filed: 1999-07-20
Abstract: The present invention is a method and apparatus for microscopic vibrational imaging using coherent Anti-Stokes Raman Scattering or Sum Frequency Generation. The spatial resolution is attained by minimizing the spot size of the optical interrogation beams on the sample. Minimizing the spot size relies upon a) directing at least two substantially co-axial laser beams (interrogation beams) through a microscope objective providing a focal spot on the sample; b) collecting a signal beam together with a residual beam from the at least two co-axial laser beams after passing through the sample; c) removing the residual beam; and d) detecting the signal beam thereby creating said pixel. The method has significantly higher spatial resolution than IR  microscopy and higher sensitivity than spontaneous Raman microscopy with much lower average excitation powers.

Abstract: A system and method for characterizing the contents of an input audio signal and for suppressing noise components of the input audio signal are described.  The audio signal is divided into a number of frequency domain input signals. Each frequency domain input signal can be processed separately to determine its intensity change, modulation frequency, and time duration characteristics to characterize the frequency domain input signal as containing a desirable signal or as a type of noise.  An index signal is calculated based on a combination of the determined characteristics and signals identified as noise are suppressed in comparison to signals identified as desirable to produce a set of frequency domain output signals with reduced noise. The frequency domain output signals are combined to provide an output audio signal corresponding to the input audio signal but having suppressed noise components and comparatively enhanced desirable signal components.

Abstract: The invention provides an isolated nucleic acid encoding Ethylene Response Factor 1 (ERF1), an early responsive gene, encoding a GCC-box binding protein in the ethylene gas signaling pathway in plants. Also provided and characterized is the peptide ERF1, as well as methods of using ERF1 or its expression product to modulate the response in plants or plant cells to ethylene. Moreover, because ERF1 acts downstream of EIN3 and all previously identified members of the signaling pathway, and because constitutive expression of ERF1 results in the modulation of a variety of ethylene response genes and phenotypes, the invention provides novel and useful methods for regulating the ethylene signaling pathway.
