Maximum Variation of Total Risk

نویسنده

  • Robin Pemantle
چکیده

Let Z > 0 be a random time. The total risk of discovering Z in the next time interval (t, t + dt) is never more variable than an exponential of mean one, which is achieved when the information up to time t is σ(Z ∧ t).

A total variation diminishing high resolution scheme for nonlinear conservation laws

In this paper we propose a novel high resolution scheme for scalar nonlinear hyperbolic conservation laws. The aim of high resolution schemes is to provide at least second order accuracy in smooth regions and produce sharp solutions near the discontinuities. We prove that the proposed scheme that is derived by utilizing an appropriate flux limiter is nonlinear stable in the sense of total varia...

تخصیص بهینه افت مجاز در زیرواحدهای سیستم آبیاری بارانی کلاسیک ثابت- آبپاش متحرک

To maintain a high system-uniformity and also acceptable water use efficiency in a solid-set sprinkler irrigation system, the total committed pressure variation to subunits should not exceed 20% of the pressure head of the sprinkler which operates with the average pressure. Although some references often recommend giving the major part of this pressure variation to laterals, a scientific and pr...

Toll Like Receptor-4 896A/G Gene Variation, a Risk Factor for Migraine Headaches

Background: The pathogenesis of migraine involves immune-mediated mechanisms in the vascular endothelium. Toll like receptor 4 (TLR-4) is a signaling receptor of innate immunity which plays a role in various neuropathologies related to neuron inflammation. Objective: This case/control study is aimed to investigate whether TLR- 4 896A/G variation is related to migraine headaches in an Iranian po...
