Interactions Between Active Matters and Endogenous Fields
Advanced Materials, EarlyView.This review synthesizes endogenous field information and computational methods in contexts such as cancer, wounds, and biofilms. It organizes NAMs and AAMs by sensing, transmitting, and executing functions, compares their limitations, and from these contrasts proposes design strategies for next‐generation AAMs, offering perspectives to foster ...

Advanced Materials, EarlyView.Observation and detection of neurotransmitter dynamics in aqueous system has been hurdle for analytical fields due to its weak and reversible nature. A terahertz‐nanodisc metasurface which implements comprehensive detection over conformational change and selective sensing is introduced. Utilizing the THz regime photonics and biomimetic environment with

A Multiscale Guide to Brownian Motion
, 2015 We revise the Levy's construction of Brownian motion as a simple though still rigorous approach to operate with various Gaussian processes. A Brownian path is explicitly constructed as a linear combination of wavelet-based "geometrical features" at ...

Approximation of Fractional Brownian Motion by Martingales [PDF]
Methodology and Computing in Applied Probability, 2012 We study the problem of optimal approximation of a fractional Brownian motion by martingales. We prove that there exist a unique martingale closest to fractional Brownian motion in a specific sense. It shown that this martingale has a specific form. Numerical results concerning the approximation problem are given.

Shaping Microbial Motion with Light: A Contactless Approach Using Diffusioosmotic Flow
Advanced Materials Interfaces, EarlyView.Light‐controlled, contactless manipulation of cyanobacteria using photoresponsive azobenzene surfactants. Reversible photo‐isomerization generates surface flow, enabling precise trapping, relocation, and directional control of single cells or ensembles with adjustable light intensity and wavelength for noninvasive, spatiotemporally resolved microbial ...

Small values and functional laws of the iterated logarithm for operator fractional Brownian motion
Open MathematicsThe multivariate Gaussian random fields with matrix-based scaling laws are widely used for inference in statistics and many applied areas. In such contexts, interests are often Hölder regularities of spatial surfaces in any given direction.

Impulsive stochastic fractional differential equations driven by fractional Brownian motion
Advances in Difference Equations, 2020 In this research, we study the existence and uniqueness results for a new class of stochastic fractional differential equations with impulses driven by a standard Brownian motion and an independent fractional Brownian motion with Hurst index 1 ...
