Test of the Skyrme Effective Field Theory Using Quenched Lattice QCD

The Skyrme effective field theory is tested by evaluating nucleon ground state matrix elements of the correlation functions for two flavor density operators and two pseudoscalar density operators in the Skyrme model and comparing them with results in quenched lattice QCD. The possiblility of using quenched lattice QCD to study higher-order terms in effective field theory is also discussed.Comment: 20 pages in TeX, 6 figures added using "figures", MIT-CTP-200

Digital compression algorithms for HDTV transmission

Digital compression of video images is a possible avenue for high definition television (HDTV) transmission. Compression needs to be optimized while picture quality remains high. Two techniques for compression the digital images are explained and comparisons are drawn between the human vision system and artificial compression techniques. Suggestions for improving compression algorithms through the use of neural and analog circuitry are given

Deep Space Network utilization for flight projects, calendar year 1981

A report on the utilization of the Deep Space Network during calendar year 1981 in support of all flight projects is presented. The network expended 63% of its total capability in support of Space Flight projects

Normal Mode Spectrum of the Deuteron in the Skyrme Model

The normal mode spectrum of the deuteron in the Skyrme model is computed. We find a bound doublet mode below the pion mass, which can be related to the well-known $90^{\circ}$ scattering of two skyrmions. We also find a singlet `breather' mode and another doublet above the pion mass. The qualitative pattern of the spectrum is similar to that recently found for the B=4 multiskyrmion. The symmetries of all the vibrational modes are presented.Comment: LaTeX, 10 pages, 3 figure

Unraveling the Veil: The Concepts of Limited Liability and Disregard of the Corporate Entity

An overview of limited liability and the doctrine of piercing the corporate veil. I focus on the factors courts consider in determining whether to disregard the corporate entity

alpha^2 corrections to parapositronium decay: a detailed description

We present details of our recent calculation of alpha^2 corrections to the parapositronium decay into two photons. These corrections are rather small and our final result for the parapositronium lifetime agrees well with the most recent measurement. Implications for orthopositronium decays are briefly discussed.Comment: 18 pages, late
