Brownian diffusion in non-harmonic potentials

Soft Matter
We propose a method to access the diffusion coefficient D within a generic confining potential. It is based on comparing the original MSD with those obtained from simulations made within the specific potential, retrieved from the Boltzmann relation.

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.

Information Design for Early‐Stage Dose‐Finding Trials

Naval Research Logistics (NRL), EarlyView.
ABSTRACT To enhance enrollment rates in early‐stage dose‐finding clinical trials, we propose an information design approach, where the clinical investigator (CI) commits to an information releasing mechanism (IRM) based on the treatment's uncertain efficacy and toxicity to encourage patients to participate in the trial.

Brownian 'supermodel' for diffusion

Journal of Physics A: Mathematical and Theoretical
Abstract Principal Gaussian models of diffusion are: Brownian motion (BM); scaled BM; fractional BM; and power BM. These models are limited in their capacity to display anomalous behaviors: sub-diffusion and super- diffusion; aging and anti-aging; and persistence and anti-persistence.

Physics‐Informed Neural Networks for Battery Degradation Prediction Under Random Walk Operations

Quality and Reliability Engineering International, EarlyView.
ABSTRACT This study addresses the challenge of predicting the state of health (SoH) and capacity degradation in Battery Energy Storage Systems (BESS) under highly variable conditions induced by frequent control adjustments. In environments where random walk behavior prevails due to stochastic control commands, conventional estimation methods often ...

Bottom‐Up Synthesis and Active Assembly of DNA Networks by Biomolecular Nanomachines

Small, EarlyView.
This study demonstrates a dynamic, bottom‐up assembly of DNA materials driven by two biomolecular nanomachines: DNA polymerase and kinesin. Through sequential chemical synthesis and motor‐driven mechanical manipulation, DNA fibrous networks are dynamically formed with complex morphologies unattainable by self‐assembly alone.

Single-file diffusion of active Brownian particles

The Journal of Chemical Physics
Single-file diffusion (SFD) is a key mechanism underlying transport phenomena in confined physical and biological systems. In a typical SFD process, microscopic particles are restricted to moving in a narrow channel where they cannot pass one another, resulting in constrained motion and anomalous long-time diffusion.

From Passive to Active: Self‐Propelled Colloids in Coatings Formulation and Film Formation

Small, EarlyView.
Self‐propelled Janus colloids are introduced into coating formulations to overcome passive transport limitations during drying. Careful balance of particle activity and evaporation timescales results in their accumulation at both coating interfaces as well as an orientational bias at the top surface.

Virtual Overlay Staining With Plasmonic Oligomer Metasurface

Small, EarlyView.
A scalable plasmonic metasurface enables “virtual staining” of living cells by enhancing optical contrast from refractive index differences. Through electrostatically assembled nanoparticle oligomers on a mirror, cellular components such as nuclei, mitochondria, and lipid‐rich regions are visualized without molecular dyes. This approach simplifies cell
