Risks, 2017 Diffusions are widely used in finance due to their tractability. Driftless diffusions are needed to describe ratios of asset prices under a martingale measure.

Red Blood Cells as Endogenous Biotweezers for Optical Micromanipulation In Vivo
Advanced 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 ...

Skew Brownian Diffusions Across Koch Interfaces [PDF]
Potential Analysis, 2016 We consider planar skew Brownian motion (BM) across pre-fractal Koch interfaces $\partial Ω^n$ and moving on $\overline{Ω^n} \cup Σ^n= Ω^n_\varepsilon$. We study the asymptotic behaviour of the corresponding multiplicative additive functionals when thickness of $Σ^n$ and skewness coefficients vanish with different rates.

Advanced Science, EarlyView.Vision begins not with images but with change: the retina fires only when something moves, handing the brain a stream of spikes. A neuromorphic imaging system adopts the same strategy—an event sensor that sees like the retina, a spiking network that thinks like the brain—to track and reconstruct fully randomly moving targets through tissue (phantom ...

Advanced Science, EarlyView.Mesoporous mixed ionic‐electronic PU/PEDOT: PSS electrodes enable label‐free detection of stochastic extracellular bioelectrical dynamics in living Phaeodactylum tricornutum. Living diatoms actively modulate interfacial ionic dynamics, establishing stochastic electrochemical noise as a sensitive probe of microbial bioelectrochemical activity and a new ...

Coacervate Droplet Sequestration of Heterogeneous Nanoplastics With Elastin‐Like Polypeptides
Angewandte Chemie, EarlyView.Phase‐separated polypeptide droplets captured incidental nanoplastics as a reusable nanoplastic sink. The engineered droplets selectively partitioned nanoplastics and exhibited unique interactions depending on droplet type and nanoplastic identity, establishing biopolymer coacervates as a potential platform for nanoplastic characterization and removal.

Advanced Science, EarlyView.Water‐soluble amine‐functionalized polyhedral oligomeric silsesquioxane promotes concurrent latex coalescence and crosslinking, allowing epoxy‐functional particles to form continuous films without added volatile coalescing agents. The resulting multiscale‐reinforced waterborne coatings combine high strength, toughness, optical transparency, scratch ...
