Let TD denote the first exit time of a Brownian motion from domain D in Rn. Given domains U,W⊆Rn containing origin, we investigate cases which are more likely to have fast exits U than W, meaning P(TUP(TWt)>P(TW>t) large. T...

We have investigated the ATPase activity of simian virus 40 (SV40) large T antigen by using monoclonal antibodies as specific probes of enzymatic activity. Three hybridoma cell lines secreting anti-T antigen antibodies were derived from mice that were immunized with D2 T antigen, an SV40 T antigen-related protein. Monoclonal antibodies secreted by these hybridomas bind to three distinct T-antig...

Tissue-type plasminogen activator (t-PA) is a mosaic protein containing several distinct structural domains attached to the serine protease catalytic unit present at its COOH terminus. To investigate structure-function relationships in t-PA, we deleted the NH2-terminal domains, finger and epidermal growth factor, by genetic engineering. The genes for the parent and mutant t-PA were expressed in...

We study the Gross Conjecture on the cyclotomic function field extension k(Λf )/k where k = Fq(t) is the rational function field and f is a monic polynomial in Fq[t]. We show the conjecture in the Fermat curve case(i.e., when f = t(t− 1)) by direct calculation. We also prove the case when f is irreducible which is analogous to Weil’s reciprocity law. In the general case, we manage to show the w...

Magnetic fields are present everywhere in our environment. They are commonly measured in Tesla (T), the international unit for magnetic flux density. One Tesla is a very high magnetic field. Human exposures to such high fields occur only with magnetic resonance imaging machines (MRI machines which are used for medical imaging), which produce magnetic field levels up to a few Tesla. To describe ...

where P̂ is a linear projection onto the space of circulations, i.e., of all the flows f with Bf = 0, and ĥ is some fixed unit s-t flow. As we showed last time, once we construct a projection P (·) then we obtain an (1 − ε)-approximate maximum flow algorithm whose performance is described in the following theorem. Theorem 1 If P (·) is an α-approximate affine `∞-projection P (·) onto the space F...
