Optimal Biasing of a Self-Homodyne Optically Coherent RF Receiver

IEEE Photonics Journal, 2010
We present a technique that achieves the most efficient use of the linear dynamic range of available photodiodes without sacrificing the linearity of the radio-frequency (RF) digital receiver and photonic link based on optical phase modulation and ...

Linearizing and Forecasting: A Reservoir Computing Route to Digital Twins of the Brain

Advanced Science, EarlyView.
A new approach uses simple neural networks to create digital twins of brain activity, capturing how different patterns unfold over time. The method generates and recovers key dynamics even from noisy data. When applied to fMRI, it predicts brain signals and reveals distinctive activity patterns across regions and individuals, opening possibilities for ...

A priori error estimates for finite element methods with numerical quadrature for nonmonotone nonlinear elliptic problems [PDF]

, 2018
The effect of numerical quadrature in finite element methods for solving quasilinear elliptic problems of nonmonotone type is studied. Under similar assumption on the quadrature formula as for linear problems, optimal error estimates in the L 2 and the H
