The use of the mass term of the gauge field as a gauge fixing term, which was discussed by Zwanziger, Parrinello and Jona-Lasinio in a large mass limit, is related to the non-linear gauge by Dirac and Nambu. We have recently shown that this use of the mass term as a gauge fixing term is in fact identical to the conventional local Faddeev-Popov formula without taking a large mass limit, if one t...

The use of the mass term as a gauge fixing term has been studied by Zwanziger, Parrinello and Jona-Lasinio, which is related to the non-linear gauge Aμ = λ of Dirac and Nambu in the large mass limit. We have recently shown that this modified quantization scheme is in fact identical to the conventional local Faddeev-Popov formula without taking the large mass limit, if one takes into account the...

In this technical report we present a self-contained introduction to algorithms that solve sparse linear systems by message passing on a junction tree (a.k.a. clique tree). When solving the systemAx = b whereA is a sparse n×nmatrix, these methods require O(n · w3) time and O(n · w2) space, where w is the treewidth of A’s sparsity graph. These algorithms are useful for parallel or distributed so...

Spermiotoxic, embryotoxic and cytotoxic effects of the widely used biofouling biocide copper pyrithione (CuPt) were evaluated in bioassays to examine inhibition fertilization rate, offspring quality on early development sea urchin Paracentrotus lividus. CuPt was non-spermiotoxic for rates but frequency embryonic malformations increased a concentration-dependent manner when eggs fertilized with ...

Aflatoxin B1-contaminated feeds and foods induce various health problems in domesticated animals humans, including tumor development hepatotoxicity. B1 also has embryotoxic effects different livestock species humans. However, it is difficult to distinguish between the indirect, maternally-mediated toxic direct embryotoxicity of aflatoxin mammals. In present study, we investigated B1-induced a z...

Dipterex was teratogenic after administration by gavage (t.i.d.) at a dose level of 480 mg/kg-day to the CP rat on days 6 through 15 of gestation, but not when administered only on days 8 or 10 of gestation. A positive teratogenic response also occurred in the hamster after administration on days 7 through 11 of gestation at 400 mg/kg-day; the apparent no-effect level for the criteria studied w...
