Advanced Functional Materials, EarlyView.An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Long-time asymptotics for nonlinear growth-fragmentation equations [PDF]
Communications in Mathematical Sciences, 2012 We are interested in the long-time asymptotic behavior of growth-fragmentation equations with a nonlinear growth term. We present examples for which we can prove either the convergence to a steady state or conversely the existence of periodic solutions.

Spectral asymptotics for stable trees [PDF]
, 2010 We calculate the mean and almost-sure leading order behaviour of the high frequency asymptotics of the eigenvalue counting function associated with the natural Dirichlet form on alpha-stable trees, which lead in turn to short-time heat kernel asymptotics

Long-time asymptotics for an integrable evolution equation with a 3 x 3 Lax pair
, 2021 We derive a Riemann-Hilbert representation for the solution of an integrable nonlinear evolution equation with a 3 x 3 Lax pair. We use the derived representation to obtain formulas for the long-time asymptotics.

On the long-time asymptotics of the modified Camassa–Holm equation with step-like initial data
European Journal of Applied MathematicsWe study the long-time asymptotics for the solution of the modified Camassa–Holm (mCH) equation with step-like initial data. \begin{align*} &m_{t}+\left (m\left (u^{2}-u_{x}^{2}\right )\right )_{x}=0, \quad m=u-u_{xx}, \\[3pt] & {u(x,0)=u_0(x)\to ...

Time‐Resolved Magnetization Switching Dynamics Driven by Orbital Torques
Advanced Functional Materials, EarlyView.Du et al. reveal nanosecond magnetization switching driven by orbital currents using time‐resolved Hall detection. The measurements separate domain nucleation from domain wall propagation and show that Joule heating strongly assists switching by lowering energy barriers.

Semidiscretization and long-time asymptotics of nonlinear diffusion equations [PDF]
, 2005 We review several results concerning the long time asymptotics of nonlinear diffusion models based on entropy and mass transport methods. Semidiscretization of these nonlinear diffusion models are proposed and their numerical properties analysed.

Long-time asymptotics of the Lifshitz–Slyozov equation with nucleation
Kinetic and Related ModelsWe consider the Lifshitz-Slyozov model with inflow boundary conditions of nucleation type. We show that for a collection of representative rate functions the size distributions approach degenerate states concentrated at zero size for sufficiently large times.

Coupling time distribution asymptotics for some couplings of the Lévy stochastic area [PDF]
, 2010 We exhibit some explicit co-adapted couplings for n-dimensional Brownian motion and all its Lévy stochastic areas. In the two-dimensional case we show how to derive exact asymptotics for the coupling time under various mixed coupling strategies, using
