Fractional Moment Theory for Anomalous Transport: A Unified Framework for Lévy Flights, Fractals, and Complex Dynamical Systems

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We develop a unified mathematical framework extending classical moment theory from discrete integer orders to a continuous spectrum of real orders f>0$$ f>0 $$, providing a systematic statistical characterization of complex systems exhibiting power‐law behavior.

Existence and regulation analysis for Hilfer–Katugampola fractional neutral hemivariational dynamics with nonlocal initialization and fractional noise

Boundary Value Problems
This paper studies mild solutions and optimal control for Sobolev-type Hilfer–Katugampola fractional neutral stochastic evolution hemivariational inequalities with nonlocal initial conditions, fractional Brownian motion, and Clarke sub-differentials ...

Analysis of the Interfacial Bond Strength in Overmoulded Thermoplastic Composites

Polymer Composites, EarlyView.
Two‐step injection overmoulding process investigated in this work, showing selective gate injection over a 450 mm demonstrator beam to vary flow length and rib pull‐off mechanical testing with fractographic characterisation of the overmoulded interface.

Peptide‐based antibacterial nanoplatforms: Design principles, stimuli‐regulated behaviors, and applications

Responsive Materials, EarlyView.
Peptide‐based antibacterial nanoplatforms, encompassing self‐assembled peptides and peptide‐engineered inorganic, polymeric, and lipid nanocarriers, are systematically reviewed. The article highlights design principles and stimuli‐responsive regulation for improving peptide stability, delivery efficiency, and antibacterial performance.

How We Simulate Nanopores

Small Methods, EarlyView.
Nanopore technology has revolutionized single‐molecule sensing, yet it suffers from an inherent interpretive challenge. Molecular dynamics has emerged as a go‐to method for determining the relationship between the structure of translocating molecules and the nanopore current signals.

Terrain Synthesis and Authoring based on Iso‐Contours

Computer Graphics Forum, EarlyView.
Abstract Digital terrains are central to realistic landscape depiction, yet authoring tools must balance perceptual realism with intuitive artistic control. We propose a compact vector‐based representation that models terrain as nested iso‐contours, inspired by geomorphology and cartography.

Spectral Content of a Single Non-Brownian Trajectory

Physical Review X, 2019
Time-dependent processes are often analyzed using the power spectral density (PSD) calculated by taking an appropriate Fourier transform of individual trajectories and finding the associated ensemble average.

Life Cycle Consumption and Portfolio Choice Under Real Interest Rate Risk

Financial Management, EarlyView.
ABSTRACT We set up a life cycle model with real interest rate risk to demonstrate that real interest rates have implications for optimal household consumption and investments. Lower interest rates lead to higher optimal stock investments and lower consumption.

Nonlocal Changing-Sign Perturbation Tempered Fractional Sub-Diffusion Model with Weak Singularity

Fractal and Fractional
In this paper, we study the existence of positive solutions for a changing-sign perturbation tempered fractional model with weak singularity which arises from the sub-diffusion study of anomalous diffusion in Brownian motion. By two-step substitution, we
