Polarization in relativistic heavy ion collisions: a theoretical perspective [PDF]

open access: yes, 2017
We review the theoretical framework for the calculation of particle polarization in relativistic heavy ion collisions within the hydrodynamical model. The covariant decomposition of the mean spin vector is presented and open theoretical issues addressed ...

Theoretical calculation of a TiO2-based photocatalyst in the field of water splitting: A review

open access: yesNanotechnology Reviews, 2020
Currently, energy and environmental problems are becoming more serious. The use of solar energy to split water and produce clean, renewable hydrogen as an energy source is a feasible and effective approach to solve these problems.

Polarized and Unpolarized Nucleon Structure Functions from Lattice QCD [PDF]

open access: yes, 1995
We report on a high statistics quenched lattice QCD calculation of the deep-inelastic structure functions $F_1$, $F_2$, $g_1$ and $g_2$ of the proton and neutron. The theoretical basis for the calculation is the operator product expansion.

A class–field theoretical calculation [PDF]

open access: yesJournal de théorie des nombres de Bordeaux, 2008
In this paper, we give the complete characterization of the p–torsion subgroups of certain idèle–class groups associated to characteristic p function fields. As an application, we answer a question which arose in the context of Tan’s approach [6] to an important particular case of a generalization of a conjecture of Gross [4] on special values of L ...

Approximate Theoretical Calculation of Continuum Opacities [PDF]

open access: yes, 1964
An approxhnate procedure is described for the theoretical calculation of the spectral absorption coefficient produced by bound-free and free-free transitions in plasmas containing polyelectronic atoms and ions. Our method of calculation is based on the

A New 3D 10-Connected Cd(II) Based MOF With Mixed Ligands: A Dual Photoluminescent Sensor for Nitroaroamatics and Ferric Ion

open access: yesFrontiers in Chemistry, 2019
The precise unification of functional groups and photoluminescence properties can give rise to MOFs that can offer diverse applications like selective detection of nitroaromatic compounds (NACs) which are considered to be an important ingredient of ...

The Single Photon Annihilation Contributions to the Positronium Hyperfine Splitting to Order $m_e\alpha^6$ [PDF]

open access: yes, 1997
The single photon annihilation contributions for the positronium ground state hyperfine splitting are calculated analytically to order $m_e\alpha^6$ using NRQED.

Consistency of field-theoretical and kinetic calculations of viscous transport coefficients for a relativistic fluid [PDF]

open access: yes, 2002
The transport coefficients of causal relativistic dissipative fluid dynamics are calculated both in a field-theoretical and a kinetic approach. We find that the results from the traditional kinetic calculation by Israel and Stewart are modified.

The synthesis, characterization and theoretical study of nano tetrabuthylammonium trichloroiodoaluminate (III)

open access: yesOrbital: The Electronic Journal of Chemistry, 2012
There is provided a nano aluminate complex that has a quaternary ammonium cation. This nano system has an equal molar ratio of Al to N that has been prepared by reaction of an organic salt R+X- such as [(CH3)4NBr], and a Lewis acid such as AlCl3,

The three-fold theoretical basis of the Gravity Probe B gyro precession calculation [PDF]

open access: yes, 2014
The Gravity Probe B (GP-B) experiment is complete and the results are in agreement with the predictions of general relativity (GR) for both the geodetic precession, 6.6 arcsec/yr to about 0.3%, and the Lense-Thirring precession, 39 marcsec to about 19 ...
