Positivity and global existence for nonlocal advection-diffusion models of interacting populations
AIMS MathematicsWe study a broad class of nonlocal advection-diffusion models describing the behaviour of an arbitrary number of interacting species, each moving in response to the nonlocal presence of others.

Advanced Intelligent Discovery, EarlyView.Deep learning‐based denoising models are applied to DNA data storage systems to enhance error reduction and data fidelity. By integrating DnCNN with DNA sequence encoding methods, the study demonstrates significant improvements in image quality and correction of substitution errors, revealing a promising path toward robust and efficient DNA‐based ...

Spatio-temporal Bazykin’s model with space-time nonlocality
Mathematical Biosciences and Engineering, 2020 This work deals with a reaction-diffusion model for prey-predator interaction with Bazykin's reaction kinetics and a nonlocal interaction term in prey growth. The kernel of the integral characterizes nonlocal consumption of resources and depends on space

A Nonlocal Fractional Peridynamic Diffusion Model
Fractal and Fractional, 2021 This paper proposes a nonlocal fractional peridynamic (FPD) model to characterize the nonlocality of physical processes or systems, based on analysis with the fractional derivative model (FDM) and the peridynamic (PD) model.

Anomalous Nonlocal Resistance and Spin-charge Conversion Mechanisms in Two-Dimensional Metals
, 2017 We uncover two anomalous features in the nonlocal transport behavior of two-dimensional metallic materials with spin-orbit coupling. Firstly, the nonlocal resistance can have negative values and oscillate with distance, even in the absence of a magnetic ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Carbon materials synthesized from biomass are promising candidates for supercapacitor electrodes. Various activation processes for developing carbon materials with high surface areas have been investigated. Here, a manganese monoxide (MnO)–porous‐activated carbon (AC) composite was fabricated via the chemical activation of coconut shell by the

A Generalization of the Hopf-Cole Transformation
Symmetry, Integrability and Geometry: Methods and Applications, 2013 A generalization of the Hopf-Cole transformation and its relation to the Burgers equation of integer order and the diffusion equation with quadratic nonlinearity are discussed. The explicit form of a particular analytical solution is presented.

Pattern formation in a mixed local and nonlocal reaction-diffusion system
Electronic Journal of Differential Equations, 2012 Local and nonlocal reaction-diffusion models have been shown to demonstrate nontrivial steady state patterns known as Turing patterns. That is, solutions which are initially nearly homogeneous form non-homogeneous patterns.
