Machine learning analysis of instabilities in noise-like pulse lasers
Optics Express, 2022 Neural networks have been recently shown to be highly effective in predicting time-domain properties of optical fiber instabilities based only on analyzing spectral intensity profiles. Specifically, from only spectral intensity data, a suitably trained neural network can predict temporal soliton characteristics in supercontinuum generation, as well as ...

Noisy homoclinic pulse dynamics [PDF]
, 2016 The effect of stochastic perturbations on nearly homoclinic pulse trains is considered for three model systems: a Duffing oscillator, the Lorenz-like Shimizu–Morioka model, and a co-dimension-three normal form.

NA-MEMD Is Actually What You Need for Computational Pulse Analysis
IEEE Access, 2022 Time-frequency analysis is of necessity for wrist pulse signal due to its complexity, among which, empirical mode decomposition (EMD) algorithm and its improved noise-assisted versions (such as ensemble EMD, noise-assisted multivariate EMD (NA-MEMD) and ...

Integer and fractional charge Lorentzian voltage pulses analyzed in the frame of Photon-assisted Shot Noise [PDF]
, 2012 The periodic injection $n$ of electrons in a quantum conductor using periodic voltage pulses applied on a contact is studied in the energy and time-domain using shot noise computation in order to make comparison with experiments. We particularly consider

Single molecule imaging with longer x-ray laser pulses [PDF]
, 2015 During the last five years, serial femtosecond crystallography using x-ray laser pulses has developed into a powerful technique for determining the atomic structures of protein molecules from micrometer and sub-micrometer sized crystals.

Sequential escapes: onset of slow domino regime via a saddle connection [PDF]
, 2018 We explore sequential escape behaviour of coupled bistable systems under the influence of stochastic perturbations. We consider transient escapes from a marginally stable "quiescent" equilibrium to a more stable "active" equilibrium.
