The solution of the free boundary problem for an axisymmetric partially penetrating well

The weak form of the free boundary problem for an axisymmetric partially penetrating well may be formulated as follows: find ϕ(r) ε C⁰([r₀, r₁]) and ...

FOLATE DEFICIENCY INDUCED HOMOCYSTEINEMIA

In humans on a normal diet, about 50% of homocysteine is remethylated to methionine with methyltetrahydrofolate as the methyl donor. Hence, folate deficiency may result in inadequate synthesis of the methyl do...

Porcine epidemic diarrhea virus (CV 777) and feline infectious peritonitis virus (FIPV) are antigenically related

Using gut sections from pigs infected with porcine epidemic diarrhea virus (strain CV 777) and ascitic fluid from cats which had succumbed to feline infectious peritonitis (FIP), a weak cross reaction was foun...

Two-sided bias bound of the Kaplan-Meier estimator

We prove in this paper that the bias of the Kaplan-Meier estimator functional, which always under-estimates the true value, is decreasing at an exponential rate. An application of the inequality is also given.

Simulation of evolutionary mechanism of planetary rings

We devised a numerical model of planetary ring in which the inelastic collision and the gravitation between ring particles are considered. We adopt Hill's equations and the differential algorithm of circular m...
