Dynamics and simulations of discretized Caputo-conformable fractional-order Lotka–Volterra models
Nonlinear Engineering, 2022 In this article, a prey–predator system is considered in Caputo-conformable fractional-order derivatives. First, a discretization process, making use of the piecewise-constant approximation, is performed to secure discrete-time versions of the two ...

Journal of Fourier Analysis and Applications, 2014 The authors summarize the contents of this paper in the abstract as follows: We study the boundary behavior of discrete monogenic functions, i.e. null-solutions of a discrete Dirac operator, in the upper and lower half space. Calculating the Fourier symbol of the boundary operator we construct the corresponding discrete Hilbert transforms, the ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Emerging evidence suggests that low‐frequency neural oscillations are dynamically regulated by consciousness levels, with the recovery of low cortical activity potentially serving as a neurophysiological substrate for conscious emergence. Targeted enhancement of these low‐frequency rhythms in patients with disorders of consciousness

Relationship Between Neurologic Symptoms and Signs and FMR1 Genotype in Premutation Carriers
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background and Objectives Fragile X‐associated Tremor/Ataxia Syndrome (FXTAS) is the most severe late‐onset condition caused by a premutation in the FMR1 gene, characterized by expanded CGG triplet repeats of 55–200. Clinical presentations of FXTAS, including gait ataxia, kinetic tremor, cognitive decline, and rare Parkinsonism, are linked to ...

Finite sections of truncated Toeplitz operators
, 2014 We describe the $C^*$-algebra associated with the finite sections discretization of truncated Toeplitz operators on the model space $K^2_u$ where $u$ is an infinite Blaschke product.

INFORMATIONAL ENTROPY IN SIMULATION OF ONE-DIMENSIONAL RANDOM FIELDS
TASK Quarterly, 2002 The entropy H of a continuous distribution with probability density function f(•) is defined as a function of the number of nodes (n) in a one-dimensional scalar random field.

Upscaling solid oxide electrolysis cell CFD simulations for hydrogen production
Engineering Applications of Computational Fluid MechanicsThe role of hydrogen production in the energy transition is of fundamental importance, and Solid Oxide Electrolysers (SOE) are expected to become one of the most efficient hydrogen production technologies. Upscaling Solid Oxide Electrolysis Cells (SOECs)

Discrete Surfaces Segmentation into Discrete Planes [PDF]
, 2004 This paper is composed of two parts. In the first one, we present an analysis of existing discrete surface segmentation algorithms. We show that two classes of algorithms can actually be defined according to discrete surface and plane definitions. In the second part, we prove the link between the two classes presented.
