SMEs and Certified Management Standards
Existing research on certifiable management standards (CMS) and corporate social responsibility (CSR) tends to focus on large companies and is characterised by disagreement about the role of these standards as drivers of CSR. We...

Meromorphic levy processes and their fluctuation identities
The last couple of years has seen a remarkable number of new, explicit examples of the Wiener.Hopf factorization for Levy processes where previously there had been very few. We mention, in particular, the many cases of...

Multilevel Monte Carlo simulation for Lévy processes based on the Wiener–Hopf factorisation
In Kuznetsov et al. (2011) a new Monte Carlo simulation technique was introduced for a large family of Lévy processes that is based on the Wiener–Hopf decomposition. We pursue this idea further by combining their technique with...

The hitting time of zero for a stable process
For any two-sided jumping α-stable process, where 1<α<2, we find an explicit identity for the law of the first hitting time of the origin. This complements existing work in the symmetric case and the spectrally one-sided...

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...

Ultrasonic intensification of ozone and electrochemical destruction of 1,3-dinitrobenzene and 2,4-dinitrotoluene
The removal of nitroaromatics from polluted water is difficult due to their high stability to conventional treatment methods. This paper presents a method for the destruction of 1,3-dinitrobenzene and 2,4-dinitrotoluene in...
Dynamics of Information Networks
We explore a simple model of network dynamics which has previously been applied to the study of information flow in the context of epidemic spreading. A random rooted network is constructed that evolves according to the...

BACKGROUND: There is limited evidence about predictors of health behaviour change in people with type 2 diabetes. The aim of this study was to assess change in health behaviours over one year and to identify predictors of...
New families of subordinators with explicit transition probability semigroup
There exist only a few known examples of subordinators for which the transition probability density can be computed explicitly along side an expression for its Lévy measure and Laplace exponent. Such examples are useful in...

Triangulations of monotone families I
Let K⊂Rn be a compact definable set in an o-minimal structure over R, for example, a semi-algebraic or a subanalytic set. A definable family {Sδ|0<δ∈R} of compact subsets of K is called a monotone family if Sδ⊂Sη for all...
CoSMed
This paper describes progress with our agenda of formal verification of information flow security for realistic systems. We present CoSMed, a social media platform with verified document confidentiality. The system’s kernel is...
Stochastic drift in discrete waves of nonlocally interacting particles
In this paper, we investigate a generalized model of N particles undergoing second-order nonlocal interactions on a lattice. Our results have applications across many research areas, including the modeling of migration...

The prolific backbone for supercritical superprocesses
We develop an idea of Evans and O'Connell (1994), Englander and Pinsky (1999) and Duquesne and Winkel (2007) by giving a pathwise construction of the so-called 'backbone' decomposition for supercritical superprocesses. Our...
