Machine Learning‐Driven Prediction of Microplastic Aging Processes and Environmental Risk Assessment Across Multi‐Media Systems

open access: yesAdvanced Science, EarlyView.
This perspective proposes a cohesive machine learning strategy to decode microplastic aging. It advocates for Federated Learning to dismantle global data silos and introduces the TRACE framework (TRansport, Aging, Corona, Ecotoxicity). By integrating physics‐informed modeling with causal discovery, this approach bridges the laboratory‐field gap to ...

Central limit theorems for the integrated squared error of derivative estimators [PDF]

open access: yes
A central limit theorem for the weighted integrated squared error of kernel type estimators of the first two derivatives of a nonparametric regression function is proved by using results for martingale differences and U-statistics.

A Wireless 3D Magneto‐Mechanical Stimulation Platform Drives In Situ Chondrogenic Commitment of Endogenous MSCs

open access: yesAdvanced Science, EarlyView.
An intracellular magneto‐mechanical platform utilizing MSC‐targeted nanomotors is developed. After intra‐articular delivery, these nanomotors target endogenous BMSCs and are actuated within lysosomes to execute trans‐planar rotational‐bouncing motions under a rotating‐fluctuating 3D magnetic field, generating amplified mechanical stimulation.

Dual‐Mode Conductive Hydrogel Sensor Combining Triboelectric and Piezoresistive Mechanisms for Signal Differentiation and Verification

open access: yesAdvanced Electronic Materials, EarlyView.
A hierarchical poly(vinyl alcohol)/polyaniline‐silver nanoparticle hydrogel is developed as a dual‐mode sensor to overcome single‐mechanism limitations. By synchronizing triboelectric and piezoresistive signals, this device differentiates between mechanical touch and environmental moisture, offering high sensitivity and real‐time signal decoupling ...

On Functional Central Limit Theorems for Dependent, Heterogeneous Tail Arrays with Applications to Tail Index and Tail Dependence Estimators [PDF]

open access: yes
We establish functional central limit theorems for a broad class of dependent, heterogeneous tail arrays encountered in the extreme value literature, including extremal exceedances, tail empirical processes and tail empirical quantile processes.
