A Microenvironment‐Adaptive Scaffold Rejuvenates Peripheral Nerve Regeneration During Aging Via Dual Modulation of Ferroptotic Stimuli in Schwann Cells

open access: yesAdvanced Science, EarlyView.
(i) Aging impairs peripheral nerve regeneration via its dual ferroptosis‐mediated pathologies in senescent schwann cells. (ii) The composite nerve conduit is a symbiosis niche integrating microenvironment‐responsive nanoparticles (Ga‐PTAs) and maxillofacial‐derived mesenchymal stem cells (Mmscs).

Elastomeric Core‐Conductive Shell Slurry Additive Stabilizes High‐Voltage NCM811 Cathodes via Mechanical‐Electrical Dual Regulation

open access: yesAdvanced Science, EarlyView.
A core‐shell ASA slurry additive constructs a mosaic‐like interface on high‐voltage NCM811 cathodes. This architecture decouples interfacial functions: the elastomeric core buffers mechanical stress to prevent microcracking, while the conductive shell facilitates rapid ion/electron transport, enabling mechanical‐electrical dual regulation and enhanced ...

Programmable Information Processing With Reconfigurable Self‐Contact Variable Stiffness Mechanical Metamaterial

open access: yesAdvanced Science, EarlyView.
Reconfigurable self‐contact variable stiffness metamaterials based on shape memory polymers enable programmable stiffness switching. Static arrays store and encrypt information with immunity to electromagnetic interference, while asymmetric stiffness converts symmetric vibration into directional matter transport.

Global Smoothness Preservation and Simultaneous Approximation by Multivariate Generalized Discrete Singular Operators

open access: yes, 2017
In this chapter we study the multivariate generalized discrete singular operators defined on ℝN, N ≥ 1, regarding their simultaneous global smoothness preservation property with respect to Lp-norm for 1 ≤ p ≤ ∞, by using higher order moduli of smoothness.

Green's Functions of Non‐Hermitian Systems at Exceptional Deficiency

open access: yesAdvanced Science, EarlyView.
We analyze the responses of a non‐Hermitian lattice system under the condition of exceptional deficiency (ED), when all bands in the system are formed by exceptional points. Using the frequency domain, we identify novel steady‐state responses that root in the broadband super‐Lorentzian Green's function (GF).

Random walk, excess smoothness or excess sensitivity? Evidence from literature and an application for Turkish economy [PDF]

open access: yes
This paper observes the Turkish household’ consumption data to see whether it follows random walk or not. The quarterly data covers the period from 1987:1 to 2003:4.

Smart Bioinks for 4D Bioprinting: Requirements, Design, and Applications

open access: yesAdvanced Science, EarlyView.
Smart bioinks empower 4D‐bioprinted constructs to dynamically adapt and remodel in response to stimuli, effectively biomimicking native tissues. Artificial Intelligence (AI) and Machine Learning (ML) play a guiding role in their rational design by optimizing relevant properties.

Machine Learning Potential for Calcium Silicate Hydrates With Broad Compositional and Structural Diversity

open access: yesAdvanced Science, EarlyView.
Existing machine learning potentials remain limited in their ability to generalize across the broad chemical and structural variability of C–S–H. Here, a representative DFT‐labeled dataset is constructed through large‐scale model generation, redundancy‐controlled screening, first‐principles optimization, and targeted sampling of non‐equilibrium ...
