This work presents a faster method of simulating exactly from a distribution known as a Vervaat perpetuity. A parameter of the Vervaat perpetuity is β ∈ (0,∞). An earlier method for simulating from this distributon ran in time O((2.23β)β). This earlier method utilized dominated coupling from the past that bounded a stochastic process for perpetuities from above. By extending to non-Markovian up...

this paper addresses the combined effects of couple stresses, thermal radiation, viscous dissipation and slip condition on a free convective flow of a couple stress fluid induced by a vertical stretching sheet. the cogley- vincenti-gilles equilibrium model is employed to include the effects of thermal radiation in the study. the governing boundary layer equations are transformed into a system o...

A metal-oxygen battery (sometimes referred to as a ‘metal-air’ battery) is a cell chemistry in which one of the reactants is gaseous oxygen, O2. Oxygen enters the cell typically in the positive electrode—perhaps after being separated from an inflow of air—and dissolves in the electrolyte. The negative electrode is typically a metal monolith or foil. Upon discharge, metal cations present in the ...

Polymers have a long history in medicine. Their uses to date range from traditional applications such as catheters, syringes, blood contacting extra corporeal devices to matrices for drug delivery, cell encapsulation and tissue regeneration. Polymers can be broadly classified on the basis of the reactivity of their chemical backbone (or susceptibility of the backbone to breakdown upon exposure ...

There is still uncertainty and confusion over which grades of doctor are encompassed by the title ‘nonconsultant career grade doctors’ (NCCG). They are staff grade doctors and the more senior associate specialists. Also included are doctors working in the community, previously called clinical medical officers (CMOs) and senior clinical medical officers (SCMOs), although doctors in these groups ...
