Bifurcation analysis of a semiconductor laser with filtered optical feedback [PDF]

open access: yes, 2006
We study the dynamics and bifurcations of a semiconductor laser with delayed filtered feedback, where a part of the output of the laser re-enters after spectral filtering.

Organic Diode Laser Dynamics: Rate-Equation Model, Reabsorption, Validation and Threshold Predictions

open access: yesPhotonics, 2021
We present and analyze a simple model based on six rate equations for an electrically pumped organic diode laser. The model applies to organic host-guest systems and includes Stoke-shifted reabsorption in a self-consistent manner.

Normalized boundary value problems in the model of optoelectronic oscillator delayed [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика, 2020
Purpose of this work is reduction of differential-difference-model of optic-electronic oscillator to more simple normalized boundary value problems. We study the dynamics of an optoelectronic oscillator with delayed feedback in the vicinity of the zero ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Accurate machine learning interatomic potentials for polyacene molecular crystals: application to single molecule host-guest systems

open access: yesnpj Computational Materials
Emerging machine learning interatomic potentials (MLIPs) offer a promising solution for large-scale accurate material simulations, but stringent tests related to the description of vibrational dynamics in molecular crystals remain scarce.

Modeling and Dynamic Characteristics Analysis of Blade-Disk Dual-Rotor System

open access: yesComplexity, 2020
In this paper, a simplified dynamic model of a dual-rotor system coupled with blade disk is built, and the effects of blade parameters of an aircraft engine on the dynamic characteristics of a dual-rotor system are studied.

Laser adhesion test for thermal sprayed coatings on textured surface by laser [PDF]

open access: yes, 2016
The laser shock adhesion test (LASAT) is a technique allowing the generation of high tensile stresses in materials. The LASAT consists in focusing a pulsed laser beam on a water-confined target.
