Modelling transmission of Mycobacterium avium subspecies paratuberculosis between Irish dairy cattle herds

open access: yesVeterinary Research, 2022
Bovine paratuberculosis is an endemic disease caused by Mycobacterium avium subspecies paratuberculosis (Map). Map is mainly transmitted between herds through movement of infected but undetected animals.

Explicit solutions for a probabilistic moraine preservation model

open access: yesJournal of Glaciology, 2016
If a series of glacial advances occurs over the same pathway, the moraines that are now present may constitute an incomplete record of the total history.

Homogenized dynamics of stochastic partial differential equations with dynamical boundary conditions

open access: yes, 2007
A microscopic heterogeneous system under random influence is considered. The randomness enters the system at physical boundary of small scale obstacles as well as at the interior of the physical medium.

Fate of a Naive T Cell: A Stochastic Journey

open access: yesFrontiers in Immunology, 2019
The homeostasis of T cell populations depends on migration, division and death of individual cells (1). T cells migrate between spatial compartments (spleen, lymph nodes, lung, liver, etc.), where they may divide or differentiate, and eventually die (2).

Reliability Analysis of Fatigue Failure of Cast Components for Wind Turbines

open access: yesEnergies, 2015
Fatigue failure is one of the main failure modes for wind turbine drivetrain components made of cast iron. The wind turbine drivetrain consists of a variety of heavily loaded components, like the main shaft, the main bearings, the gearbox and the ...

Diffusion Signed LMS Algorithms and Their Performance Analyses for Cyclostationary White Gaussian Inputs

open access: yesIEEE Access, 2017
As one of the signed variants of the diffusion least mean square (DLMS) algorithm over networks, the diffusion sign error algorithm has been presented in previous reference. In this paper, we propose two novel signed variants of the DLMS algorithm, i.e.,

A New Angle-Calibration Method for Precise Ultra-Short Baseline Underwater Positioning

open access: yesRemote Sensing
Ultra-short baseline (USBL) underwater positioning systems are widely used in marine scientific research and ocean engineering. Angle misalignment is a main error that reduces the accuracy of USBL underwater positioning.

The Impact of Systemic Risk on the Diversification Benefits of a Risk Portfolio

open access: yesRisks, 2014
Risk diversification is the basis of insurance and investment. It is thus crucial to study the effects that could limit it. One of them is the existence of systemic risk that affects all of the policies at the same time. We introduce here a probabilistic
