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.

Asian Option Pricing with Monotonous Transaction Costs under Fractional Brownian Motion
Journal of Applied Mathematics, 2013 Geometric-average Asian option pricing model with monotonous transaction cost rate under fractional Brownian motion was established. The method of partial differential equations was used to solve this model and the analytical expressions of the Asian ...

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 ...

Nonparametric Regression with Subfractional Brownian Motion via Malliavin Calculus
Abstract and Applied Analysis, 2014 We study the asymptotic behavior of the sequence Sn=∑i=0n-1K(nαSiH1)(Si+1H2-SiH2), as n tends to infinity, where SH1 and SH2 are two independent subfractional Brownian motions with indices H1 and H2, respectively. K is a kernel function and the bandwidth

Advanced Science, EarlyView.CDegSR, a new tool for imaging RNA at single molecule level in living cells was developed by researchers. Background noise was eliminated by protein engineering and making it degrade when not bound to its target. This allowed individual RNA molecules to be clearly imaged and tracked.

Advanced Science, EarlyView.High‐throughput Differential Dynamic Microscopy measures frequency‐resolved mechanical fingerprints from 3 to 10 μL$\umu{\rm L}$ mucus samples using only a few minutes of operator attention per sample. This automated analysis enables scalable mucus phenotyping for translational research by distinguishing mechanical heterogeneity among donors, disease ...

Advanced Science, EarlyView.The Janus nanomotors leverage an “asymmetric structure‐driven functional synergy” strategy to orchestrate spatiotemporally coordinated catalytic functions, in situ self‐amplifying NO generation, and deep tumor penetration, thereby enabling controllable, sustained, and uniform NO generation within the tumor microenvironment.

Abstract and Applied Analysis, 2014 Option pricing is always one of the critical issues in financial mathematics and economics. Brownian motion is the basic hypothesis of option pricing model, which questions the fractional property of stock price. In this paper, under the assumption that
