Comparative studies of IR spectra of deprotonated serine with classical and thermostated ring polymer molecular dynamics simulations [PDF]

open access: yesStructural Dynamics, 2021
Here we report the vibrational spectra of deprotonated serine calculated from the classical molecular dynamics (MD) simulations and thermostated ring-polymer molecular dynamics (TRPMD) simulation with third-order density-functional tight-binding.

Monte Carlo Simulations of ED-XRF Spectra as an Authentication Tool for Nuragic Bronzes

open access: yesHeritage, 2021
The high artistic and cultural relevance of particular objects, in this case from the Nuragic civilization, have stimulated the growth of a forgery industry, replicating small bronze boats (navicelle), statues (bronzetti), and other objects.

Measurement of leakage neutron spectra with D-T neutrons and evaluated nuclear data [PDF]

open access: yesEPJ Web of Conferences, 2020
Benchmarking of evaluated neutron nuclear data libraries was performed for ∼14.8 MeV neutrons on the several targets, such as gallium, graphite, silicon carbide, uranium and tungsten samples.

Theoretical investigation of geometric configurations and vibrational spectra in citric acid complexes [PDF]

open access: yesMaterials Research, 2014
The performance of advanced electronic ceramics is directly related to the synthesis route employed. Sol-gel methods are widely used for this purpose. However, the physicochemical intermediate steps are still not well understood. Better understanding and

Evaluating Snow Microwave Radiative Transfer (SMRT) model emissivities with 89 to 243 GHz observations of Arctic tundra snow [PDF]

open access: yesThe Cryosphere, 2023
Improved modelling of snow emissivity is needed to improve the assimilation of surface-sensitive atmospheric sounding observations from satellites in polar regions for numerical weather prediction (NWP). This paper evaluates emissivity simulated with the

Self-consistent 3D Radiative Transfer for Kilonovae: Directional Spectra from Merger Simulations

open access: yesThe Astrophysical Journal Letters, 2023
We present 3D radiative transfer calculations for the ejecta from a neutron star merger that include line-by-line opacities for tens of millions of bound–bound transitions, composition from an r -process nuclear network, and time-dependent thermalization

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

open access: yesEPJ 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

open access: yesAtmosphere, 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 ...
