We describe and experimentally compare three theoretically well-known algorithms for the parallel prefix (or scan, in MPI terms) operation, and give a presumably novel, doubly-pipelined implementation of the in-order binary tree parallel prefix algorithm. Bidirectional interconnects can benefit from this implementation. We present results from a 32 node AMD Cluster with Myrinet 2000 and a 72-no...

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...

As support for sexual reorientation therapy—the practice of trying to change an individual’s sexual orientation—has lulled1, various therapists have been faced with the question of how to effectively and respectfully counsel their religious clients who are at odds with their sexual orientation. They appear to be faced with two options, a sexuality affirming approach and a newer approach known a...

In today’s world carrying a number of plastic smart cards to establish our identity has become an integral segment of our routine lives. Identity establishment necessitates a pre stored readily available data about self and to the administrator to authenticate it with claimer’s personal information. There is a distinct requirement of a technological solution for nationwide multipurpose identity...

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...
