LLE Review, Volume 73 45 In cold processing of optical glasses by microgrinding,1,2 the resulting brittle-material-removal rate induces a cracked layer near the glass surface, referred to as subsurface damage (SSD). [Editor’s note: The acronym for subsurface damage (SSD) used in this article should not be confused with its more common use as an acronym for smoothing by spectral dispersion.] In ...
By ROBERT SCHREK, FREDERICK W. PRESTON AND ALBERT A. DIErz A PRELIMINARY REPORT’ showed that rabbit anti-dog lymphocyte serum was more toxic in vitro to leukemic than to normal human lymphocytes. This paper presents detailed data on the toxicity of this immune heterobogous serum. As the dog lymphocytes have the Forssman antigen and rabbits are Forssman negative,2 it was necessary to consider wh...

The top shows current source amplifiers used with a loop array, the bottom shows ultra-low output impedance amplifiers used with a partially decoupled rung array. The current source amplifiers provide higher levels of decoupling, but are unable to generate as much current as the ultra-low output impedance amplifiers. 7333 A Comparison of Isolating Amplifier Architectures Neal Hollingsworth, Kat...

Abstract In this paper, we propose a method that estimates the variance of an imputed estimator in multistage sampling design. The is based on rescaling bootstrap for introduced by Preston (Surv Methodol 35(2):227–234, 2009). his original version, resampling requires dataset includes only complete cases and no missing values. Thus, two modifications applying to nonresponse imputation. These are...
