Analysis of the recording of Fibonacci lenses using photopolymers with 3-D diffusion model [PDF]
EPJ Web of Conferences, 2023 In the present work, a 3-Dimensional diffusion model is proposed to predict the main properties of Diffractive Optical Elements (DOEs), recorded in photopolymers, including refractive index modulation and the evolution of the transverse intensity ...

Fringe Pattern Denoising using U-Net based neural network [PDF]
EPJ Web of Conferences, 2020 Fringe visibility and noise removal, are key success factors in interferometric techniques, where novel deep learning techniques can be applied. We test the use U-Net deep convolutional network applied to the obtained interference images, trained with an

Measurements and estimation of the columnar optical depth of tropospheric aerosols in the UV spectral region [PDF]
Annales Geophysicae, 2002 We report values of the columnar tropospheric aerosol optical depth at UV wavelengths based on experimental measurements of the direct spectral irradiances carried out by a commercial spectroradiometer (Li1800 of Licor company) covering the range ...

Passively Modelocked All-PM Thulium-Doped Fiber Laser at 2.07
IEEE Photonics Journal, 2022 Here we present a self-started passively mode-locked thulium-doped fiber laser with in-band pumping at 1561 nm that fully retains polarization and emits beyond 2 μm.

A protocol to study bacteriophage adaptation to new hosts
STAR Protocols, 2021 Summary: A general protocol for the experimental assessment of bacteriophage adaptation to new hosts is described. We use as a model system the lytic phage T7 and an engineered E. coli strain modified to hamper the recruitment of a known proviral factor.

Time crystal dynamics in a weakly modulated stochastic time delayed system
Scientific Reports, 2022 Time crystal oscillations in interacting, periodically driven many-particle systems are highly regular oscillations that persist for long periods of time, are robust to perturbations, and whose frequency differs from the frequency of the driving signal ...

Evidence for a role of phenotypic mutations in virus adaptation
iScience, 2021 Summary: Viruses interact extensively with the host molecular machinery, but the underlying mechanisms are poorly understood. Bacteriophage T7 recruits the small protein thioredoxin of the Escherichia coli host as an essential processivity factor for the

Propagação de ondas aplicadas ao mapeamento geológico: formulação acústica
Revista Brasileira de Ensino de Física, 2021 O conceito de onda é recorrente nas ciências pura e aplicada, servindo de base para compreender desde terremotos, passando pelas telecomunicações e eletromagnetismo, até a difração de nêutrons, e.g., para citar um caso quântico.
