The efficacy of standard potency Edmonston-Zagreb (E-Z) measles vaccine was tested in a randomized trial of Black infants in a rural area of South Africa where a measles epidemic was occurring. The following immunization schedules were used: 48 infants aged 4-8.5 months who received 3.9 log 50 infectious units of E-Z vaccine (group A); 48 infants aged 4-8.5 months who received 3.28 log 50 infec...

In recent years, attention has been devoted to the development of efficient iterative solvers for the solution of the linear system of equations arising from the discontinuous Galerkin (DG) discretization of a range of model problems. In the framework of two level preconditioners, scalable non-overlapping Schwarz methods have been proposed and analyzed for the h–version of the DG method in the ...

In this paper we develop a new class of overlapping Schwarz type algorithms for solving scalar steady and unsteady convection di usion equations discretized by nite element or nite di erence methods The preconditioners consist of two components namely the usual additive Schwarz preconditioner and the sum of some second order terms constructed by using products of ordered neighboring subdomain p...

We prove a sharp Schwarz lemma type inequality for the Weierstrass–Enneper parameterization of minimal disks. It states following. If F:D→Σ is conformal harmonic disk Σ⊂R3, where D unit and |Σ|=πR2, then |Fx(z)|(1−|z|2)≤R. some z previous equality, surface an affine image disk, F linear up to Möbius transformation disk.

Expository notes on the Schwarz lemma born out of some lectures given subject.
