Random walks and Lévy processes as rough paths [PDF]
, 2015 We consider random walks and Lévy processes in a homogeneous group G. For all $$p > 0$$p>0, we completely characterise (almost) all G-valued Lévy processes whose sample paths have finite p-variation, and give sufficient conditions under which a sequence ...

Two coupled Lévy queues with independent input
Stochastic Systems, 2014 We consider a pair of coupled queues driven by independent spectrally-positive Lévy processes. With respect to the bi-variate workload process this framework includes both the coupled processor model and the two-server fluid network with independent ...

The evolutionary maintenance of Lévy flight foraging.
PLoS Computational Biology, 2022 Lévy flight is a type of random walk that characterizes the behaviour of many natural phenomena studied across a multiplicity of academic disciplines; within biology specifically, the behaviour of fish, birds, insects, mollusks, bacteria, plants, slime ...

Estimates of densities for Lévy processes with lower intensity of large jumps [PDF]
, 2015 We obtain general lower estimates of transition densities of jump Lévy processes. We use them for processes with Lévy measures having bounded support, processes with exponentially decaying Lévy measures for large times and for processes with high ...

Optically Active Birefringent Polymer–Lipid Hybrid Microparticles With Dual‐Stimuli Responsiveness
Advanced Optical Materials, EarlyView.The present study reports on geometrically tunable, magnetic and NIR‐stimuli‐responsive anisotropic microparticles that exhibit intrinsic birefringence due to their lamellar crystalline architecture, enabling label‐free detection under a polarized light.

Lévy Processes on Quantum Permutation Groups [PDF]
, 2015 We describe basic motivations behind quantum or noncommutative probability, introduce quantum Levy processes on compact quantum groups, and discuss several aspects of the study of the latter in the example of quantum permutation groups. The first half of

Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Growing demand for healthier beverages is driving innovation in the wine sector, with dealcoholized wine emerging as a promising alternative. However, little is known about the contextual conditions under which consumers would choose dealcoholized wine, particularly in countries with strong wine traditions. To fill this gap, this work examines

Continuous Time Autoregressive Moving Average Processes Driven by Semi-Levy Process
پژوهشهای ریاضی, 2020 Introduction A flexible and tractable class of linear models is Autoregressive moving average (ARMA) process that are in effect of discrete noises. The continuous time ARMA (CARMA) processes have wide applications in many data modeling where are more ...

Global Dirichlet Heat Kernel Estimates for Symmetric Lévy Processes in Half-Space [PDF]
, 2015 In this paper, we derive explicit sharp two-sided estimates for the Dirichlet heat kernels of a large class of symmetric (but not necessarily rotationally symmetric) Lévy processes on half spaces for all t>0$t>0$. These Lévy processes may or may not have

U.S. Agriculture, Biofuel Markets, and Trade: Challenges and Opportunities
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Using an enhanced Computable General Equilibrium (CGE) model (GTAP‐BIO), this study assesses how the expansion in demand for Electric Vehicles (EVs) and the reduction in exports of agricultural products induced by trade disputes negatively affect US agriculture.
