we derive closed formulas for the prices of european options andtheir sensitivities when the underlying asset follows a double-exponentialjump diffusion model, as considered by s. kou in 2002. this author hasderived the option price by making use of double series where each termrequires the computation of a sequence of special functions, such thatthe implementation remains difficult for a large...

TheWiener-Hopf factorization of a complex function arises in a variety of fields in applied mathematics such as probability, finance, insurance, queuing theory, radio engineering and fluid mechanics. The factorization fully characterizes the distribution of functionals of a random walk or a Lévy process, such as the maximum, the minimum and hitting times. Here we propose a constructive procedur...

Environmentalists target their own behaviour choices as part of identity, including recycling, transportation, and clothing. Based on interviews with older adult environmentalists, we investigate whether environmentalism extends beyond lives. That is, do they want to be disposed or dispersed upon death? In terms environmentalism, then, considering the materials involved, one’s body, how might e...

In the vertebrate neural tube, a morphogen-induced transcriptional network produces multiple molecularly distinct progenitor domains, each generating different neuronal subtypes. Using an in vitro differentiation system, we defined gene expression signatures of distinct progenitor populations and identified direct gene-regulatory inputs corresponding to locations of specific transcription facto...

In recent years several techniques for exceeding the program’s data-flow constraints have been proposed. These include value prediction, instruction reuse, and dependency redirection. In this paper we show how they can be regarded as one universal method of performing what we term result reuse. We study in depth the dependency redirection derivative and propose several hardware schemes to accom...

The mobile phone has become one of the essential objects that people carry when they leave home. By conducting a series of street interviews in 11 cities on 4 continents, we attempted to identify the main carrying options in different cultures and how these options affected user experience in interacting with the phone. We also identified several cultural differences ranging from the prevalence...

Abstract There is a growing interest in understanding development processes and opportunities small medium-sized towns that so far did not attract much attention mainstream urban theory. Conventional growth-oriented approaches fail to capture the complexity of local policy-making because they prioritise production factors underrate role discourse place-based identity. This paper aims explore li...
