Multiscale Modelling of the Electrocatalysis of Microenzymes: Insights Into the Performance of Microperoxidase at an Aqueous/Graphene Interface and Their Exploitation to Improve Performance

open access: yesAdvanced Science, EarlyView.
A novel multiscale MD/DFT framework to elucidate microenzyme adsorption and electron transfer is reported. This method reveals distinct configurations for microperoxidase‐11 on graphene and those best suited for electron transfer. Rate constants align with the limited experimental data, establishing this framework as a tool for optimizing microenzyme ...

Karhunen-Loève Expansion for the Second Order Detrended Brownian Motion

open access: yesAbstract and Applied Analysis, 2014
Based on the norm in the Hilbert Space L2[0,1], the second order detrended Brownian motion is defined as the orthogonal component of projection of the standard Brownian motion into the space spanned by nonlinear function subspace.

Haloarchaea swim slowly for optimal chemotactic efficiency in low nutrient environments

open access: yesNature Communications, 2020
Brownian motion places the ultimate limit on microorganisms’ ability to navigate. Thornton et al. show that Haloarchaea have a strategy of slow swimming and infrequent reorientation that exploits the randomising nature of Brownian motion to achieve ...

Option Pricing in a Fractional Brownian Motion Environment [PDF]

open access: yes
The purpose of this paper is to obtain a fractional Black-Scholes formula for the price of an option for every t in [0,T], a fractional Black-Scholes equation and a risk-neutral valuation theorem if the underlying is driven by a fractional Brownian ...

On Energy Inequalities [PDF]

open access: yes, 2000
We consider the Schrödinger operator H=−Δ2+q in a bounded domain D in Rd, d≥3, with q in the Kato class Kd(D) and finite gauge g(x)=Ex[exp∫τ0q(Xs)ds], where (Xt) is a Brownian motion and τ is the first exit time of the Brownian motion (Xt) from the ...

Bound Water as a Reinforcing Element for Ultra‐Strong Polyacrylamide

open access: yesAdvanced Science, EarlyView.
Rather than acting as a conventional plasticizer, bound water serves as a reinforcing element in polyacrylamide by constructing strong PAM–water–PAM hydrogen‐bond networks. This water‐mediated architecture delivers ultra‐high mechanical strength and exceptional flame resistance, redefining the role of water in polymer reinforcement.

Brownian confidence bands on Monte Carlo output [PDF]

open access: yes, 2005
When considering a Monte Carlo estimation procedure, the path produced by successive partial estimates is often used as a guide for informal convergence diagnostics. However the confidence region associated with that path cannot be derived simplistically

A Unifying Thermodynamic Model for Phase Separation and Aging of Biopolymers

open access: yesAdvanced Science, EarlyView.
Phase separation and aging of intrinsically disordered proteins are placed in a unifying framework. A thermodynamically consistent time‐dependent version of associating‐polymer theory shows how the processes are intricately coupled. Assuming aging to occur through interacting sites resulting from reversible conformational transitions, the model ...

On Skew Brownian Motion

open access: yesThe Annals of Probability, 1981
We consider the stochastic equation $X(t) = W(t) + \beta l^X_0(t)$, where $W$ is a standard Wiener process and $l^X_0(\cdot)$ is the local time at zero of the unknown process $X$. There is a unique solution $X$ (and it is adapted to the fields of $W$) if $|\beta| \leq 1$, but no solutions exist if $|\beta| > 1$.

Red Blood Cells as Endogenous Biotweezers for Optical Micromanipulation In Vivo

open access: yesAdvanced Science, EarlyView.
By synergistically integrating the long‐distance manipulation fiber probe (LDMFP) and endogenous red blood cells (RBCs) as biocompatible optical elements, a natural RBC biotweezer was developed for the desired microparticle manipulation and immune cell activation within living vasculature, which might offer an alternative tool for intravital optical ...
