Non-perturbative saddle point for the effective action of disordered and interacting electrons in 2D

, 2000
We find a non-perturbative saddle-point solution for the non-linear sigma model proposed by Finkelstein for interacting and disordered electronic systems.

Self‐Assembled Myricetin‐Arginine Conjugate Nanozymes for Targeted Suppression of Joint Inflammation and Osteoclastogenesis in Rheumatoid Arthritis

Advanced Science, EarlyView.
Carrier‐free myricetin‐arginine conjugate nanozymes (MANZs) have been fabricated through a Mannich reaction and spontaneous self‐assembly. MANZs selectively accumulate in inflamed joints by targeting M1 macrophages via CAT2‐mediated uptake. The nanozymes can effectively modulate macrophage polarization, suppress osteoclast differentiation, and mitigate

Morse Thoery of Saddle Point Reduction with Applications

Axioms
In this paper, we demonstrate that when saddle point reduction is applicable, there is a clear relationship between the Morse index and the critical groups before and after the reduction.

Emergence of chaotic attractor and anti-synchronization for two coupled monostable neurons

, 2004
The dynamics of two coupled piece-wise linear one-dimensional monostable maps is investigated. The single map is associated with Poincare section of the FitzHugh-Nagumo neuron model.

Diffusion Characteristics of Ru and Oxygen Vacancies in Ta2O5 for Resistive Random Access Memory Devices: A Density Functional Theory Investigation

Advanced Electronic Materials, EarlyView.
Atomistic analysis of ruthenium (Ru) and oxygen vacancy (OV) diffusion in Ta₂O₅‐based memristors is performed. DFT calculations demonstrate interstitial Ru in Ta₂O₅ has lower diffusion barriers and formation energies than OVs, enhancing mobility and stability.

Stability Estimates and Structural Spectral Properties of Saddle Point Problems

, 2012
For a general class of saddle point problems sharp estimates for Babu\v{s}ka's inf-sup stability constants are derived in terms of the constants in Brezzi's theory.

Insights on SEI Growth and Properties in Na‐Ion Batteries via Physically Driven Kinetic Monte Carlo Model

Advanced Energy Materials, EarlyView.
The novel kinetic Monte Carlo model presented here incorporates spatially‐ and time‐dependent electrical potential, which enables the precise study of the solid electrolyte interphase formation in Na‐ion batteries. The effects of electrolyte composition and charging conditions on the growth and behavior of the solid electrolyte interphase during the ...

Dynamics of Lennard-Jones clusters: A characterization of the activation-relaxation technique

, 2000
The potential energy surface (PES) of Lennard-Jones clusters is investigated using the activation-relaxation technique (ART). This method defines events in the configurational energy landscape as a two-step process: (a) a configuration is first activated
