Anecdotal , Historical and Critical Commentaries on Genetics Edited by James F . Crow and William F . Dove Sonneborn and the Cytoplasm
IN the late 1930s when Tracy Sonneborn was in graduate school and just starting his work on the genetics of protozoa, classical studies on genetics were almost finished. The second edition of Principles of Genetics by E. W. Sinnott and L. C. Dunn (1932) that appeared in that period was quite sophisticated, containing a good account of chromosome theory, segregation ratios produced by complex ge...

متن کاملFalse Alarm Rate Estimation for Information-Theoretic-Based Source Enumeration Methods
The Tracy-Widom distribution is used to determine the false alarm rate of information theoretic methods that statistically estimate the number of sources in a multichannel receiver input. The Tracy-Widom distribution is the limiting distribution for the largest eigenvalue of a covariance matrix having a central white Wishart distribution. Such covariance matrices are produced by the output of m...
متن کاملThe Genotypic Control of Kappa in Paramecium Aurelia, Syngen 4, Stock 51.
HE killer trait in all stocks of Paramecium aurelia which have been investiTgated has been found to depend upon the presence of a cytoplasmic factor, kappa, carried by killers but absent from sensitive animals (SONNEBORN 1943). Kappa is a DNA containing particle of about one micron in size (PREER 1950a; PREER and STARK 1953). When kappa disappears from the cytoplasm of a killer, the animal lose...
متن کاملFar - UV FUSE spectroscopy of the O vi resonance doublet in Sand 2 ( WO ) Paul
We present Far-Ultraviolet Spectroscopic Explorer (FUSE) spectroscopy of Sand 2, a LMC WO-type Wolf-Rayet star, revealing the Ovi resonance P Cygni doublet at 1032–38Å. These data are combined with HST/FOS ultraviolet and Mt Stromlo 2.3m optical spectroscopy, and analysed using a spherical, non-LTE, lineblanketed code. Our study reveals exceptional stellar parameters: T∗ ∼150,000K, v∞=4100 km s...
