The extended hypergeometric class of Lévy processes
We review and extend the class of hypergeometric Lévy processes explored in Kuznetsov and Pardo (2013) with a view to computing fluctuation identities related to stable processes. We give the Wiener-Hopf factorisation of a...

Chemical signals act as the main reproductive barrier between sister and mimetic Heliconius butterflies.
Colour pattern is the main trait that drives mate recognition between Heliconius species that are phylogenetically close. However, when this cue is compromised such as in cases of mimetic, sympatric and closely related species...

Occupation times of refracted Lévy processes
A refracted Lévy process is a Lévy process whose dynamics change by subtracting off a fixed linear drift (of suitable size) whenever the aggregate process is above a pre-specified level. More precisely, whenever it exists, a...

On the appearance of nitrite anion in [PdX(OAc)L<sub>2</sub>] and [Pd(X)(C∧N)L] syntheses (X = OAc or NO<sub>2</sub>)
Pd 3(OAc) 5NO 2, an impurity in "Pd(OAc) 2" {formally Pd 3(OAc) 6}, emerges as a serious issue in the synthesis of pure Pd II complexes derived from Pd(OAc) 2, for example in our C-H activation precatalyst, Pd(OAc) 2(pip) 2 (pip...

A new benchmark problem for electromagnetic modelling of superconductors
Abstract: The high-T c superconducting (HTS) dynamo is a promising device that can inject large DC supercurrents into a closed superconducting circuit. This is particularly attractive to energise HTS coils in NMR/MRI magnets and...

Circulating vitamin C and digestive system cancers
BACKGROUND & AIMS: Vitamin C is an antioxidant with a potential role in the prevention of digestive system cancers, but there is yet no consensus whether vitamin C has a causal role in these cancers. The aim of this study was to...

Exact and asymptotic <em>n</em>-tuple laws at first and last passage
Understanding the space time features of how a Levy process crosses a constant barrier for the first time, and indeed the last time, is a problem which is central to many models in applied probability such as queueing theory...

Hitting distributions of α-stable processes via path censoring and self-similarity
In this paper we return to the problem of Blumenthal-Getoor-Ray, published in 1961, which gave the law of the position of first entry of a symmetric alpha-stable process into the unit ball. Specifically, we are interested in...

Male sex pheromone components in Heliconius butterflies released by the androconia affect female choice.
Sex-specific pheromones are known to play an important role in butterfly courtship, and may influence both individual reproductive success and reproductive isolation between species. Extensive ecological, behavioural and genetic...
