Self-similar solutions of a multi-phase Stefan problem on the half-line

open access: yesСовременная математика: Фундаментальные направления
In this paper, we study self-similar solutions of the multiphase Stefan problem for the heat equation on the half-line x 0 with constant initial data and Dirichlet or Neumann boundary conditions. In the case of the Dirichlet boundary condition, we prove

The Quasistationary Phase Field Equations with Neumann Boundary Conditions

open access: yesJournal of Differential Equations, 2000
The paper considers the quasistationary phase field equations \[ \partial_t(u+ \varphi)- \Delta u= f\quad\text{in }\Omega\times ]0,T[, \] \[ \partial_\nu u= 0\quad\text{on }\partial\Omega\times ]0, T[, \] \[ (u+\varphi)(0)= w_0, \] and \[ -2\varepsilon\Delta\varphi+ {1\over\varepsilon} W'(\varphi)= u\quad\text{in }\Omega\times ]0, T[, \] \[ \partial_ ...

Review of Memristors for In‐Memory Computing and Spiking Neural Networks

open access: yesAdvanced Intelligent Systems, EarlyView.
Memristors uniquely enable energy‐efficient, brain‐inspired computing by acting as both memory and synaptic elements. This review highlights their physical mechanisms, integration in crossbar arrays, and role in spiking neural networks. Key challenges, including variability, relaxation, and stochastic switching, are discussed, alongside emerging ...

Ferroelectric Tunnel Junction Memristor Crossbar Array with Annealing Optimization for In‐Memory Computing

open access: yesAdvanced Intelligent Systems, EarlyView.
A 48 × 48 ferroelectric tunnel junction (FTJ) crossbar array is fabricated and optimized through postmetallization annealing, enabling stable polarization switching and reliable multilevel conductance programming. Half‐bias operation, accurate vector–matrix multiplication with less than 1% error, and CIFAR‐10 image classification with near‐software ...
