Computer simulation of the skin reflectance spectra [PDF]

Computer Methods and Programs in Biomedicine, 2003
The reflectance spectra of the human skin in visible and near-infrared (NIR) spectral region have been calculated using the Monte Carlo technique, and the specular and internal reflection on the medium surface is taken into account. Skin is represented as a complex inhomogeneous multi-layered highly scattering and absorbing medium. The model takes into

Simulations of Structure and Vibrational Spectra of Deoxyoctanucleotides [PDF]

The Journal of Physical Chemistry B, 2005
Combined molecular dynamics and ab initio computations were applied for analysis of infrared absorption and vibrational circular dichroism spectra of deoxyoctanucleotides. Unlike for previous idealized models, molecular geometries of these shorter DNA fragments in solutions were obtained as dynamic averages from simulations in a periodic water box ...

Testing of almost all the hadronic interaction models by comparing calculated muon energy spectrum with data [PDF]

EPJ Web of Conferences, 2019
Uncertainties of the model energy spectra of the most energetic secondary charged mesons are discussed. Computer simulations of the partial energy spectra of the atmospheric vertical muons induced by primary cosmic particles with various fixed energies ...

Recurrence Spectra of European Temperature in Historical Climate Simulations

Atmosphere, 2019
We analyse and quantify the recurrences of European temperature extremes using 32 historical simulations (1900–1999) of the fifth Coupled Model Intercomparison Project (CMIP5) and 8 historical simulations (1971–2005) from the EUROCORDEX ...

Tracking X-Ray Source Movement in a Retracting Flux Tube

The Astrophysical Journal, 2023
Solar flares produce sources of localized, enhanced X-ray emission, thought to be due to the acceleration of nonthermal electrons and the transport of energy away from the reconnection site.

Improved Huygens’ Principle for Metamaterial

Crystals, 2023
In this paper, we propose a new method based on Huygens’ principle for calculations of transmission spectra with weak coupling and we call this method an improved Huygens’ principle.

Effect of Protein Conformation and AMP Protonation State on Fireflies’ Bioluminescent Emission

Molecules, 2019
The emitted color in fireflies’ bioluminescent systems depends on the beetle species the system is extracted from and on different external factors (pH, temperature…) among others.

Micromagnetic simulations of absoption spectra [PDF]

Journal of Magnetism and Magnetic Materials, 2006
Further development of a previously introduced method for numerically simulating magnetic spin waves is presented. Together with significant improvements in speed, the method now allows one to calculate the energy absorbed by the various modes excited by a position- and time-dependent H1 field in a ferromagnetic body of arbitrary shape in the presence ...
