Optimal Strong Rates of Convergence for a Space-Time Discretization of the Stochastic Allen–Cahn Equation with Multiplicative Noise [PDF]
Comput. Methods Appl. Math., 2017 The stochastic Allen–Cahn equation with multiplicative noise involves the nonlinear drift operator 𝒜(x)=Δx-(|x|2-1)x{{\mathscr{A}}(x)=\Delta x-(|x|^{2}-1)x}.

Controller design of systems with multiplicative noise [PDF]
IEEE Transactions on Automatic Control, 1985 Continuous stochastic systems acted upon by scalar multiplicative and vector additive noises are considered. First examined is the problem of finite-horizon control of such a stochastic system with time-varying parameters under the additional constraint of incomplete state information.

Machine Learning‐Enabled Polymer Discovery for Enhanced Pulmonary siRNA Delivery
Advanced Functional Materials, EarlyView.This study provides an efficient approach to train a machine learning model by merging heterogeneous literature data to predict suitable polymers for siRNA delivery. Without the need for extensive laboratory synthesis, the machine learning enabled a virtual screening and successfully predicted a polymer that is validated for effective gene silencing in

Power-law tails from multiplicative noise
, 2004 We show that the well-known Langevin equation, modeling the Brownian motion and leading to a Gaussian stationary distribution of the corresponding Fokker-Planck equation, is changed by the smallest multiplicative noise.

State-dependent diffusion: thermodynamic consistency and its path integral formulation [PDF]
, 2007 The friction coefficient of a particle can depend on its position as it does when the particle is near a wall. We formulate the dynamics of particles with such state-dependent friction coefficients in terms of a general Langevin equation with ...

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.

Физика волновых процессов и радиотехнические системы, 2018 The issues of quasi-optimal signal processing in conditions of simultaneous effect of additive and multiplicative non-Gaussian noise are considered. The resulting expression describing the effect on the value of the normalized a posteriori errors of ...

Chaotic Cascades with Kolmogorov 1941 Scaling
, 1993 We define a (chaotic) deterministic variant of random multiplicative cascade models of turbulence. It preserves the hierarchical tree structure, thanks to the addition of infinitesimal noise. The zero-noise limit can be handled by Perron-Frobenius theory,

Detection of multiplicative noise in stationary random processes using second- and higher order statistics [PDF]
, 2000 This paper addresses the problem of detecting the presence of colored multiplicative noise, when the information process can be modeled as a parametric ARMA process.

Near‐Field Optical Detection of Defect‐Stabilized Metallic Islands at the Verwey Transition in Fe3O4
Advanced Functional Materials, EarlyView.Nanoscale metallic islands emerging across the Verwey transition in thin films of Fe3O4 are imaged using near‐field optical microscopy from mid‐infrared to terahertz frequencies. Recurring across thermal cycles, these disorder‐stabilized islands exhibit distinct transition temperatures.
