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.

Application of the Fractal Brownian Motion to the Athens Stock Exchange
Fractal and FractionalThe Athens Stock Exchange (ASE) is a dynamic financial market with complex interactions and inherent volatility. Traditional models often fall short in capturing the intricate dependencies and long memory effects observed in real-world financial data. In

Brownian motion in a Brownian crack
The Annals of Applied Probability, 1998 Let \(Y^\varepsilon(t)\) be the reflected two-dimensional Brownian motion in Wiener sausage \(D^\varepsilon\) of width \(\varepsilon>0\) around two-sided Brownian motion \(X_1(t)\).

Coupling time distribution asymptotics for some couplings of the Lévy stochastic area [PDF]
, 2010 We exhibit some explicit co-adapted couplings for n-dimensional Brownian motion and all its Lévy stochastic areas. In the two-dimensional case we show how to derive exact asymptotics for the coupling time under various mixed coupling strategies, using

Advanced Science, EarlyView.Field‐driven active colloids are framed as distributed micromachines in which externally supplied power, sensing, and control regulate task‐relevant states. By closing the loop between particle behavior, imaging, computation, and electric or magnetic actuation, these systems can progress from programmable motion toward adaptive functional outcomes ...

Advanced Science, EarlyView.Fluorinated β‐glucan/pectin nanogels enable colon‐targeted oral delivery of astilbin through gastrointestinal protection, β‐glucanase‐responsive release, mucus penetration, and prolonged retention. The released astilbin attenuates senescence‐associated features of CD4+ T cells and promotes Treg responses, while the nanogel matrix modulates the gut ...

Stochastic flows and sticky Brownian motion [PDF]
Sticky Brownian motion is a one-dimensional diffusion with the property that the amount of time the process spends at zero is of positive Lebesgue measure and yet the process does not stay at zero for any positive interval of time ...

Scaling limit for the random walk on the largest connected component of the critical random graph [PDF]
, 2012 In this article, a scaling limit for the simple random walk on the largest connected component of the Erdos-Rényi random graph G(n,p) in the critical window, p = n−1+λn−4/3, is deduced.

Catalytic Luminescent Polymer Micromotors With Shape‐Programmed Motion
Advanced Science, EarlyView.A Janus micromotor is designed with an SiO2/Ti/ITO/PFN‐Br/Pt heterostructure with an engineered energy level. The ITO conductive interlayer facilitates efficient charge separation, generating interfacial electric fields and ionic gradients for enhanced light‐driven propulsion.
