Mittag–Leffler Memory Kernel in Lévy Flights
Mathematics, 2019 In this article, we make a detailed study of some mathematical aspects associated with a generalized Lévy process using fractional diffusion equation with Mittag−Leffler kernel in the context of Atangana−Baleanu operator.

Adaptive Lévy walks in foraging fallow deer. [PDF]
PLoS ONE, 2009 BACKGROUND: Lévy flights are random walks, the step lengths of which come from probability distributions with heavy power-law tails, such that clusters of short steps are connected by rare long steps.

First passage and first hitting times of Lévy flights and Lévy walks
New Journal of Physics, 2019 For both Lévy flight and Lévy walk search processes we analyse the full distribution of first-passage and first-hitting (or first-arrival) times. These are, respectively, the times when the particle moves across a point at some given distance from its ...

Computational Methods for Tracking, Quantitative Assessment, and Visualization of C. elegans Locomotory Behavior. [PDF]
PLoS ONE, 2015 The nematode Caenorhabditis elegans provides a unique opportunity to interrogate the neural basis of behavior at single neuron resolution. In C. elegans, neural circuits that control behaviors can be formulated based on its complete neural connection map,

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

Enhancement of stability of metastable states in the presence of Lévy noise
SciPost PhysicsThe barrier-crossing event for superdiffusion characterized by symmetric Lévy flights is analyzed. Starting from the fractional Fokker-Planck equation, we derive an integro-differential equation along with the necessary conditions to calculate the mean ...

F1000Research, 2023 Background. For survival of the organism, T cells must efficiently control pathogens invading different peripheral tissues. Whether or not such control is achieved by utilizing different movement strategies in different tissues remains poorly understood.

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.

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.ABSTRACT Post‐traumatic stress disorder (PTSD) causes significant mental and physical distress, yet only a small subset of individuals exposed to trauma develop the disorder. Scientists and clinicians are still unable to predict who will get the disorder or how it will manifest.

Levy Flights in Metaheuristics Optimization Algorithms – A Review
Applied Artificial Intelligence, 2018 In recent years, Levy flight (LF) is increasingly being employed as search mechanism in metaheuristics optimization algorithms (MOA) to solve complex real world problems.
