Line of Sight Detection with the Talk Eye

Line-of-Sight Percolation

Given ω ≥ 1, let Z2(ω) be the graph with vertex set Z 2 in which two vertices are joined if they agree in one coordinate and differ by at most ω in the other. (Thus Z2(1) is precisely Z .) Let pc(ω) be the critical probability for site percolation in Z2(ω). Extending recent results of Frieze, Kleinberg, Ravi and Debany, we show that limω→∞ ωpc(ω) = log(3/2). We also prove analogues of this resu...

Line of sight and alternative representations of aberrations of the eye.

Several methods for representing pupil plane aberrations based on wavefront height, slope, and curvature are discussed. The choice of reference axis and reference surface is shown to strongly affect the appearance of the representation. Special attention will be paid to the use of the line of sight (the line from the fixation point to the center of the pupil) as the reference axis. We show that...

The Variation of Magnesium Depletion with Line of Sight Conditions

In this paper we report on the gas-phase abundance of singly-ionized magnesium (Mg II) in 44 lines of sight, using data from the Hubble Space Telescope (HST). We measure Mg II column densities by analyzing mediumand highresolution archival STIS spectra of the 1240 Å doublet of Mg II. We find that Mg II depletion is correlated with many line of sight parameters (e.g. f(H2), EB−V , EB−V /r, AV , ...

Part 1271.85 a (5) Syphilis testing should not be required for eye tissue. Dr. Marian Macsai et al documented that syphilis is not transmitted from donor to recipient by cornea1 transplant. Dr. Jay Pepose documented the ineffectiveness of using syphilis testing as a marker for other diseases. Additionally, unnecessary syphilis screening would result in a 7.5% increase in the cost of serology te...
