Optical Modeling of Spectral Backscattering and Remote Sensing Reflectance From Emiliania huxleyi Blooms

open access: yesFrontiers in Marine Science, 2018
In this study we develop an analytical model for spectral backscattering and ocean color remote sensing of blooms of the calcifying phytoplankton species Emiliania huxleyi. Blooms of this coccolithophore species are ubiquitous and particularly intense in

Observation of optical spring effect in a microtoroidal optomechanical resonator [PDF]

open access: yes, 2007
We present experimental evidence of the optical spring effect in a silica microtoroid resonator. The variation of the measured mechanical resonant frequency as a function of optical power, optical coupling, and optical detuning is in very good agreement ...

Sensitivity analysis of a bio-optical model for Italian lakes focused on Landsat-8, Sentinel-2 and Sentinel-3

open access: yes, 2015
We analysed the sensitivity of a Case-2 bio-optical model where the water reflectance is computed as a function of concentrations of three optical water quality parameters (WQPs) of three Italian lakes (Garda, Mantua and Trasimeno) and their specific ...

Probing the Elastic Scattering Differential Cross Section for Al + p at Backward Angles in a Low Energy Regime

open access: yesUniverse, 2023
We report on the absolute differential cross section for proton elastic scattering on aluminum in the energy range of 0.8 MeV to 2.1 MeV. In the literature we have found previously published data that follow similar trends but are not consistent with one

Unified Statistical Channel Model for Turbulence-Induced Fading in Underwater Wireless Optical Communication Systems [PDF]

open access: yesIEEE Transactions on Communications, 2018
A unified statistical model is proposed to characterize turbulence-induced fading in underwater wireless optical communication (UWOC) channels in the presence of air bubbles and temperature gradient for fresh and salty waters, based on experimental data.

Isotopic effects in elastic and inelastic 12,13C + 16,18O scattering [PDF]

open access: yesЯдерна фізика та енергетика, 2010
New angular-distribution data of 13С + 18О elastic and inelastic scattering at the energy Elab(18O) = 105 MeV were obtained for the transitions to the ground and excited states 3.088 MeV(1/2+), 3.555 MeV (1/2-), 3.854 MeV (5/2+) of 13С and 1.982 MeV (2+

Elastic and inelastic scattering of 15N ions by 12C nuclei at energy 81 MeV

open access: yesЯдерна фізика та енергетика, 2018
ew angular distributions of the 15N + 12C elastic and inelastic scattering were measured at the energy Elab (15N) = 81 MeV. The data were analyzed within the coupled-reaction-channels method (CRC). The elastic and inelastic scattering as well as the more

Optical Flow Estimation Using a Spatial Pyramid Network [PDF]

open access: yesComputer Vision and Pattern Recognition, 2016
We learn to compute optical flow by combining a classical spatial-pyramid formulation with deep learning. This estimates large motions in a coarse-to-fine approach by warping one image of a pair at each pyramid level by the current flow estimate and ...

Production cross–section and reaction yield calculations for 123-126I isotopes on 123Sb(α,xn) reactions

open access: yesKuwait Journal of Science, 2021
Most of the radioisotopes that used in medical field, like examination and treatment studies, were produced by employing nuclear reactions. Within the process of a nuclear reaction, one of the most important parameter is the cross–section data which help
