Fractal–fractional modeling and chaos analysis of a financial system with generalized memory kernels

open access: yesResults in Control and Optimization
Chaotic behavior in financial systems strongly influences investment strategies, risk management, and policy decisions. Conventional fractional calculus, however, has limitations in capturing the memory and scaling effects that characterize such ...

Modelling Fractal Waves on Shallow Water Surfaces via Local Fractional Korteweg-de Vries Equation

open access: yesAbstract and Applied Analysis, 2014
A mathematical model of fractal waves on shallow water surfaces is developed by using the concepts of local fractional calculus. The derivations of linear and nonlinear local fractional versions of the Korteweg-de Vries equation describing fractal waves ...

Revealing the Underlying Mechanisms in Performance Enhancement of Shellular Lattice Electrodes During Anion Exchange Membrane Water Electrolysis Process

open access: yesAdvanced Science, EarlyView.
Micro laser powder bed fusion enables architected nickel shellular lattice gas diffusion layers for anion exchange membrane water electrolysis. Among regular open cell geometries, the Gyroid lattice promotes bubble release, convective reactant replenishment and continuous electron transport, delivering low overpotentials, enhanced charge transfer and ...

Single‐Molecule Imaging of Endogenous RNA Using a Miniaturized and Circularly Permuted CRISPR‐Cas13 Degron‐Masking System CDegSR

open access: yesAdvanced Science, EarlyView.
CDegSR, a new tool for imaging RNA at single molecule level in living cells was developed by researchers. Background noise was eliminated by protein engineering and making it degrade when not bound to its target. This allowed individual RNA molecules to be clearly imaged and tracked.

TNAP and PHOSPHO1 Function Synergistically to Afford Critical Control Over the Mineralization of the Postnatal Murine Skeleton

open access: yesAdvanced Science, EarlyView.
Biomineralization underpins skeletal development, yet its molecular control remains incompletely understood. Using a novel murine knockout model, this study reveals the essential and complementary roles of PHOSPHO1 and TNAP in postnatal skeletal development.

Local fractional variational iteration algorithm II for non-homogeneous model associated with the non-differentiable heat flow

open access: yesAdvances in Mechanical Engineering, 2015
In this article, we begin with the non-homogeneous model for the non-differentiable heat flow, which is described using the local fractional vector calculus, from the first law of thermodynamics in fractal media point view. We employ the local fractional
