Saphenous vein autograft had opened a new erra in revascularization of mycardium in cases with severe angina pectoris. This has attracted the attention of many medical enters so that a rae of 7595% relief of pain has been obtained. 92% of patients have demonstrated sings of cure of choronary iSJChemia and have moved to group 1 from those of group 2, 3, and 4 (dassi­f[ca,tion of American Heart A...

Functions which control the access to data in groupware should be flexibly designed by offering different options to the end users. However, conflicts might arise among different end users in the process of selecting one of these options. To support users in finding a consentaneous solution for these conflicts, we propose a metafunction called "negotiability". We propose to define and explore t...

Binomial trees are very popular in both theory and applications of option pricing. As they often suffer from an irregular convergence behavior, improving this is an important task. We build upon a new version of the Edgeworth expansion for lattice models to construct new and quickly converging binomial schemes with a particular application to barrier options.

This paper is concerned with the quantum properties of the binomial model (or, the CRR-model). We show that the single-step binomial model is incomplete in the quantum setting. All risk-neutral states of the single-step binomial model in the quantum setting are characterized. Moreover, it is shown that all single-step models are incomplete in the quantum setting. Therefore, incompleteness is ba...

A general method to construct recombinant tree approximations for stochastic volatility models is developed and applied to the Heston model for stock price dynamics. In this application, the resulting approximation is a four tuple Markov process. The first two components are related to the stock and volatility processes and take values in a two-dimensional binomial tree. The other two component...

BACKGROUND Parkinson's disease (PD) patients' own knowledge and experience and access to information, in relation to advanced treatment methods, are very limited. The aim of this study was to map out PD patients' perception about various advanced treatment methods, their availability and regional differences in medical care, and to investigate patients' experience of their medication and qualit...

This paper proposes a new efficient algorithm for the computation of Greeks for options using the binomial tree. We also show that Greeks for European options introduced in this article are asymptotically equivalent to the discrete version of Malliavin Greeks. This fact enables us to show that our Greeks converge to Malliavin Greeks in the continuous time model. The computation algorithms of Gr...

Recent research has proposed methods for enhancing the performance of multicast in networks with irregular topologies. These methods fall into two broad categories: (a) network interface (NI) based schemes that make use of enhanced functionality of the software/firmware running at the NI processor, and (b) switch-based methods that use enhancements to the switch architecture to support hardware...

We thank the editor and an anonymous referee. Any errors are our own. Abstract Using the WACC to Value Real Options We present a real option valuation using the weighted average cost of capital (WACC). This is an alternative to risk-neutral real option valuation. Using the WACC involves a marginal increase in mathematical complexity, but it is easy to implement in a spreadsheet, and it is easy ...
