Monte Carlo simulation of coherent effects in multiple scattering [PDF]

, 2005
Using a combination of the stochastic Monte Carlo technique and the iteration procedure of the solution to the Bethe-Salpeter equation, it has been shown that the simulation of the optical path of a photon packet undergoing an nth scattering event ...

Multiple-Penalty-Weighted Regularization Inversion for Dynamic Light Scattering

Applied Sciences, 2018
By using different weights to deal with the autocorrelation function data of every delay time period, the information utilization of dynamic light scattering can be obviously enhanced in the information-weighted constrained regularization inversion, but ...

Thermal hysteresis in microtubule assembly/disassembly dynamics: The aging-induced degradation of tubulin dimers

Biochemistry and Biophysics Reports, 2022
The assembly/disassembly of biological macromolecules plays an important role in their biological functionalities. Although the dynamics of tubulin polymers and their super-assembly into microtubule structures is critical for many cellular processes ...

Deep-tissue focal fluorescence imaging with digitally time-reversed ultrasound-encoded light. [PDF]

, 2012
Fluorescence imaging is one of the most important research tools in biomedical sciences. However, scattering of light severely impedes imaging of thick biological samples beyond the ballistic regime.

Nano-biosensor based on the combined use of the dynamic and static light scattering for Aspergillus galactomannan analysis

Sensing and Bio-Sensing Research, 2022
A biosensor based on the analyte-induced aggregation of functionalized nanoparticles recorded using two optical signals of different physical nature is developed. The hydrodynamic diameter of the conjugates, measured by the dynamic light scattering (DLS)

Dynamic light sheet generation and fluorescence imaging behind turbid media

Journal of the European Optical Society-Rapid Publications, 2018
Background Light sheet microscopy became a popular tool allowing fast imaging with reduced out of focus light. However, when light penetrates turbid media such as biological tissues, multiple scattering scrambles the illumination into a speckle pattern ...

Two tractable models of dynamic light scattering and their application to Fano resonances

Nanophotonics, 2021
We introduce two tractable analytical models to describe dynamic effects at resonant light scattering by subwavelength particles. One of them is based on a generalization of the temporal coupled-mode theory, and the other employs the normal mode approach.
