A Systematic Approach to Analyze T Cell Migration: Application to Mouse Melanoma Tumors
Advanced Therapeutics, EarlyView.The results show that a minimum of two migration speeds can be rigorously identified from the data with cells switching between a fast, persistent migratory state, and a slow, random migration state. These results will help in identifying genetic factors that influence rapid migration, among other applications, such as quality control for CAR‐T cell ...

Stochastic Current of Bifractional Brownian Motion
Journal of Applied Mathematics, 2014 We study the regularity of stochastic current defined as Skorohod integral with respect to bifractional Brownian motion through Malliavin calculus. Moreover, we similarly derive some results in the case of multidimensional multiparameter.

RANDOM WALKS AND FRACTAL STRUCTURES IN AGRICULTURAL COMMODITY FUTURES PRICES [PDF]
This paper investigates whether the assumption of Brownian motion often used to describe commodity price movements is satisfied. Using historical data from 17 commodity futures contracts specific tests of fractional and ordinary Brownian motion are ...

Advanced Therapeutics, EarlyView.Green tea polyphenols, conjugated either covalently or non‐covalently to hemp protein, comprise an excellent stabilizing matrix for oxidatively‐sensitive small molecules. These nanoemulsions are highly stable to a variety of chemical and physical stressors, protecting the small molecule while allowing for easy uptake across cell membranes and rapid ...

Coupling of lever arm swing and biased Brownian motion in actomyosin.
PLoS Computational Biology, 2014 An important unresolved problem associated with actomyosin motors is the role of Brownian motion in the process of force generation. On the basis of structural observations of myosins and actins, the widely held lever-arm hypothesis has been proposed, in

Stochastic Processes and their Applications, 2015 We prove strong existence and uniqueness for a reflection process $X$ in a smooth, bounded domain $D$ that behaves like obliquely-reflected-Brownian-motion, except that the direction of reflection depends on a (spin) parameter $S$, which only changes when $X$ is on the boundary of $D$ according to a physical rule.

Advanced Theory and Simulations, EarlyView.Magnetoelectric nanoparticles exploit cancer cells' electrical vulnerabilities—altered membrane charge and higher capacitance—to achieve tumor‐specific targeting without bioreagents. MATLAB simulations reveal how electromagnetic forces create targeting specificity, while external magnetic fields enhance precision. This may enable wirelessly controlled,

Liquid Crystal‐Driven Chemical Feeding Accelerates Condensation Reactions in Droplet Microreactors
Advanced Science, EarlyView.This work introduces a liquid crystal (LC)‐based platform for dynamic chemical feeding in droplet microreactors, enabling unprecedented control over reaction kinetics and mass transfer. By leveraging LC phase transition‐mediated release, new pathways are unlocked for enhancing confined reaction environments, advancing the fundamental capabilities of ...
