The Asymptotic Stability of the Generalized 3D Navier-Stokes Equations

Journal of Applied Mathematics, 2013
We study the stability issue of the generalized 3D Navier-Stokes equations. It is shown that if the weak solution u of the Navier-Stokes equations lies in the regular class ∇u∈Lp(0,∞;Bq,∞0(ℝ3)), (2α/p)+(3/q)=2α ...

Deep Learning‐Assisted Rapid Bacterial Classification Based on Raman Spectroscopy of Bacteria Lysed by Acoustically Driven Fiber‐Tip Vibration

Advanced Science, EarlyView.
A novel acoustofluidic lysis technique based on a vibrating fiber‐tip is integrated with Raman spectroscopy and deep learning for rapid, label‐free bacterial classification. By exposing intracellular biomolecules, this method significantly enhances spectral resolution, enabling high‐accuracy classification with a 1D‐ResNet model.

Reproductive solutions for the g-Navier-Stokes and g-Kelvin-Voight equations

Electronic Journal of Differential Equations, 2016
This article presents the existence of reproductive solutions of g-Navier-Stokes and g-Kelvin-Voight equations. In this way, for weak solutions, we reach basically the same result as for classic Navier-Stokes equations.

Electrochemistry as a Tool for Redox‐Based Bio‐Information Processing

Advanced Science, EarlyView.
Redox is a modality that is native to biology and accessible to electronics through electrochemistry. Imposed electronic inputs are transduced into redox signals that can probe for bio‐information or actuate biological responses. Measured electronic output responses are analyzed to reveal actionable information.
