Interpreting flow cytometry data: a guide for the perplexed

Leonore A Herzenberg, James Tung, Wayne A Moore, Leonard A Herzenberg, David R Parks
2006 Nature Immunology  
Some of the light from this fluorochrome, however, may be emitted and detected in the wavelength range assigned to a different fluorochrome.  ...  The remaining cells are displayed as dots that, as in all dot plots, increase in number as the number of cells analyzed increases.  ...

Is motion processing unitary?

William A. Simpson, Velitchko Manahilov, Melissa S. Mair
1999 Optical Society of America. Journal A: Optics, Image Science, and Vision

Spatial frequency discrimination in cyclopean vision

P.M Grove, D Regan
2002 Vision Research  
The dot density of every cyclopean grating used was chosen bearing in mind our finding that three or more spatial samples per grating cycle are required before sampling effects can be ignored.  ...  It is well known that inspecting a cyclopean grating causes threshold for detecting a subsequently presented test cyclopean grating to be elevated, and that the threshold elevation is greatest at the adapting  ...  Air Force Office of Scientific Research or of the US Government.  ...

Motion detection in interleaved random dot patterns: Evidence for a rectifying nonlinearity preceding motion analysis

George Mather, Hilary Tunley
1995 Vision Research  
Subjects could specify shift direction correctly even when eight different patterns were interleaved, provided that the duration of each frame was brief.  ...  Computed responses from such detectors successfully predicted psychophysical performance with interleaved random patterns. Implications for models of motion analysis are discussed.  ...  Acknowledgements-This work was supported by grants from the MRC and BBSRC.  ...

Poor visibility of motion in depth is due to early motion averaging

Julie M Harris, Simon K Rushton
2003 Vision Research  
Under a variety of conditions, motion in depth from binocular cues is harder to detect than lateral motion in the frontoparallel plane.  ...  This suggests that the motion in depth signal is lost due to early motion averaging, rather than due to the presence of noise from the perceived depth patterns in the stimulus.  ...  First, the cloud of dots with an independent disparity sample added from a rectangular distribution, as was used in Experiment 1.  ...
