Abstract:
A luminescence measuring system is provided for detecting luminescence at extremely low concentrations of luminescing moieties. The method employs alternating radiation at a plurality of loci of an inhomogenous solution, where the radiant power is maintained constant, and the irradiated volumes of pairs of loci are systematically varied. With the probability being very low that the same luminescence signal will be obtained in the two or more measurements, by comparing the measurements, one can detect a low luminescence signal in the presence of relatively high noise levels. Various techniques are described for modulating the irradiance and detecting changes in signal.

Abstract:
An apparatus for forming a differential image of a specimen is disclosed. The two images whose difference is used to generate the differential image are made by illuminating said specimen with polarized light, each image corresponding to illuminating the specimen with light of a different polarization. The intensity of the differential image at each point is related to the difference in intensities observed when the point in question is illuminated with light having the different polarizations divided by the sum of said observed intensities. The present invention includes a light source for illuminating the image with polarized light having a polarization which oscillates between first and second preselected states of polarization, said oscillations occurring at a predetermined frequency. The intensity of light leaving each of a preselected plurality of points on the specimen is measured as a function of time by a light detecting apparatus which generates an electrical signal which is related to the intensity of light at the preselected point in question. This electrical signal is used as input to a lock-in amplifier referenced to said predetermined frequency.

Sen. Elizabeth Warren apologizes ‘for harm that I have caused’ to Native Americans
Warren discussed her family heritage with her older brothers, including a story of how her fathers family looked down on her mother because of her familys Native American ancestry. Also removed was a memo by geneticist Carlos Bustamante, who analyzed the results of the DNA test she took.
