Veterinary Dermatology, Volume 34, Issue 6, Page 543-553, December 2023., 2023 Background – Hymenoptera envenomation with honey bee (Apis mellifera) and paper wasp (Polistes spp.) may cause life‐threatening anaphylaxis in dogs. In human patients, clinical history, intradermal testing (IDT) and measurement of allergen‐specific serological immunoglobulin (Ig)E (sIgE) are used to support a diagnosis of Hymenoptera venom ...

Veterinary Dermatology, Volume 33, Issue 1, Page 17-e6, February 2022., 2022 Background – Because of the increased incidence of multidrug‐resistant (MDR) bacteria, the use of disinfectants over antibiotics has been encouraged. However, the interactions between disinfectants and host local immunity are poorly understood. Objective – To assess the effects of chlorhexidine digluconate (Chx), with and without selected host defence ...

Bulletin of the London Mathematical Society, Volume 53, Issue 6, Page 1749-1765, December 2021., 2021 Abstract In the 1988 textbook Fractals Everywhere, Barnsley introduced an algorithm for generating fractals through a random procedure which he called the chaos game. Using ideas from the classical theory of covering times of Markov chains, we prove an asymptotic formula for the expected time taken by this procedure to generate a δ‐dense subset of a ...

The number of overtakes in an M/M/2 queue
Operations Research Perspectives, 2018 The phenomenon of overtaking in queueing systems and queueing networks has been addressed by several authors with various motivations in the last decades. Nevertheless, up to now, for the relatively simple M/M/2/FCFS queue, the distribution of the number

COVER TIME FOR THE FROG MODEL ON TREES
Forum of Mathematics, Sigma, 2019 The frog model is a branching random walk on a graph in which particles branch only at unvisited sites. Consider an initial particle density of $\unicode[STIX]{x1D707}$ on the full $d$-ary tree of height $n$.

Recursive estimation of the claim rates and sizes in an insurance model
International Journal of Stochastic Analysis, Volume 2004, Issue 3, Page 245-259, 2004., 2004 It is a common fact that for most classes of general insurance, many possible sources of heterogeneity of risk exist. Premium rates based on information from a heterogeneous portfolio might be quite inadequate. One way of reducing this danger is by grouping policies according to the different levels of the various risk factors involved.

International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 62, Page 3957-3962, 2003., 2003 Since coming to the attention of the general news media several years ago, the paradoxical combination of two losing games into a winning game by J. M. R. Parrondo has been the subject of numerous numerical investigations and simulations. This note provides a clear statement of the nature of the paradox together with a straightforward analysis and ...

Filtering and predicting the cost of hidden perished items in an inventory model
International Journal of Stochastic Analysis, Volume 15, Issue 3, Page 235-245, 2002., 2002 This paper is concerned with a discrete time, discrete state inventory model for items of changing quality. Items are assumed to be in one of a finite number, M, of quality classes that are ordered in such a way that Class 1 contains the best quality and the last class contains the pre‐perishable quality.

On a stochastic inventory model with deteriorating items
International Journal of Mathematics and Mathematical Sciences, Volume 25, Issue 3, Page 197-203, 2001., 2001 We suggest a new inventory continuous time stochastic model for deteriorating items. We derive optimal operating characteristics of the expected cost per unit time under the assumption that demand in each replenishment cycle forms a regenerative process. We also present numerical examples.

On the application of ergodic theory to alternating Engel series
International Journal of Mathematics and Mathematical Sciences, Volume 25, Issue 12, Page 813-819, 2001., 2001 We investigate the ergodic behaviour of the basic operator which generates the modified Engel‐type alternating series representations of any number in (0, 1] in terms of rationals.
