String Field Theories from One Matrix Models
Through the continuum limit of the one matrix model on the multicritical
point the corresponding Schwinger-Dyson equation of temporal-gauge string field
theory is derived. It agrees with that of the background independent
formulation recently proposed.Comment: 5 pages, LaTe
Studies of liver phosphorylase in hepatic injuries. I. Alteration in enzyme activity
Phosphorylase activities (total and a form) were determined in the livers of experimental hepatic injuries with carbon tetrachloride or galactosamine and the livers of patients with liver diseases. Experimental liver injuries caused a slight decrease in total activity in later stages and a marked increase in a form activity in earlier stages. In human livers, low values of total activity were found in acute hepatitis and cirrhosis of the liver with no consistent alteration in a activity. Phosphorylase activities in hepatocellular carcinomas were also low. The importance of the altered phosphorylase activities in hepatic injuries is discussed in relation to the disorder in glycogen metabolism in the injured liver.</p
Chromomagnetic Instability and Gluonic Phase

Reconsidering Composite Higgs Loop Effects in the Top Mode Standard Model
Composite Higgs loop effects in the top mode standard model are discussed by
using the Miransky-Tanabashi-Yamawaki (MTY) approach based on the
Schwinger-Dyson equation. The top mass is obtained as 179 GeV for the Planck
scale cutoff (\Lambda \simeq 10^{19} GeV). This result is different from that
of the Bardeen-Hill-Lindner (BHL) approach based on the renormalization group
equation (RGE), with QCD plus Higgs loop effects included (m_t \simeq 205 GeV).
Detailed comparison of the MTY approach with the BHL approach is made. We
derive ``RGE'' from the Pagels-Stokar formula by considering the infrared mass
as the ``renormalization point''. Then, it is found that the MTY approach
including the composite Higgs loop effects is only partially equivalent to the
BHL approach with QCD plus Higgs loop effects. The difference essentially
results from the treatment of the composite Higgs propagator, or more
precisely, of Z_H^{-1}. Our results can be summarized as m_t (Ours) \simeq
1/\sqrt{2} m_t (MTY), in contrast to m_t (BHL) \simeq \sqrt{2/3} m_t (MTY),
where m_t (MTY) \simeq 250 GeV is the original MTY prediction without Higgs
loop effects.Comment: 20 pages, PTPTeX, 5 EPS figures, 1 Table, to appear in Progress of
