Functional imaging of post-movement beta oscillations

, 1999
The linear estimation (LE) and spline surface Laplacian (SL) method were applied to single-trial EEG data. EEG was recorded in three subjects during voluntary, self-paced movements of the index finger.

Synchronization‐Dissipation in the Cardiorespiratory System

Advanced Science, EarlyView.
By modeling central nervous coupling and viscoelastic interactions in the cardiorespiratory system we show that synchronization produces a 10% gain in cardiac efficiency in humans. It is surmised that respiratory sinus arrhythmia improves cardiac pumping efficiency by reducing dynamic stress and power dissipation in the pulmonary vasculature.

Noisy oscillations in the actin cytoskeleton of chemotactic amoeba.

, 2016
Biological systems with their complex biochemical networks are known to be intrinsically noisy. Here we investigate the dynamics of actin polymerization of amoeboid cells, which are close to the onset of oscillations.

Interface Wettability Transition‐Driven Drug Release and Dual‐Phase Functionalization in Implant Abutment

Advanced Science, EarlyView.
A temporally controlled drug release coating is developed for abutments using a superhydrophobic coating self‐assembled on mesoporous silica. This surface provides sequential functionality: initial contamination resistance through non‐wetting, followed by controlled drug release via wettability transition.

Heterogeneous Visible‐Light Photocatalysis in Continuous‐Flow: A Synergistic Strategy for Challenging Trifluoromethylation of α, α‐Diaryl Allylic Alcohols via 1,2‐aryl Migration

Advanced Science, EarlyView.
A continuous‐flow photocatalytic strategy is presented for the efficient synthesis of β‐trifluoromethyl ketones under visible light. Using a recyclable solid photocatalyst and an inexpensive CF3 source, the method enables rapid reactions, easy scale‐up, and smooth integration into multistep flow synthesis of bioactive molecules.

Free oscillations in a beta-plane ocean

, 1971
This paper is concerned with the free oscillations in a rectangular equatorial beta-plane model of large oceans with a free surface placed symmetrically on the equator.

Reaction‐Induced Reversible Reconstruction Enhanced Ni‐MgO/CaO Dual Functional Material for Stable CO2 Capture and In Situ Conversion

Advanced Science, EarlyView.
A highly dispersed NiO‐MgO solid solution (MgxNi1‐xO) is created in a hierarchically porous Ca‐based matrix to protect Ni and CaO nanoparticles against carbon deposition and sintering. Owing to the reversible reconstruction of MgxNi1‐xO, this superior structure is self‐regenerative in the calcium looping dry reforming of methane process, thereby ...

Decoupling Intrinsic Molecular Efficacy From Platform Effects: An Interpretable Machine Learning Framework for Unbiased Perovskite Passivator Discovery

Advanced Science, EarlyView.
This study establishes an interpretable machine learning framework that disentangles the intrinsic molecular efficacy of passivators from experimental platform effects—enabling unbiased, high‐throughput discovery of effective perovskite surface modifiers.

Aptamer‐Directed Porous DNA Nanocomposite Hydrogel for Active Pulp Preservation: Immunomodulation, Stem Cell Recruitment and Reparative Dentinogenesis

Advanced Science, EarlyView.
This study presents an injectable DNA‐based porous hydrogel integrating catechol motifs and targeting aptamers for pulpitis management. Upon in situ crosslinking, the scaffold actively recruits endogenous dental pulp stem cells, restores redox homeostasis, and modulates immune responses.
