Integration of Particle-Gas Systems with Stiff Mutual Drag Interaction

, 2016
Numerical simulation of numerous mm/cm-sized particles embedded in a gaseous disk has become an important tool in the study of planet formation and in understanding the dust distribution in observed protoplanetary disks.

Lattice Boltzmann model approximated with finite difference expressions

, 2017
We show that the asymptotic properties of the link-wise artificial compressibility method are not compatible with a correct approximation of fluid properties.

Local freedom in the gravitational field

, 1996
In a cosmological context, the electric and magnetic parts of the Weyl tensor, E_{ab} and H_{ab}, represent the locally free curvature - i.e. they are not pointwise determined by the matter fields.

Variations of shear-wave splitting parameters in the source region of the 2023 Türkiye doublet earthquakesKey points

Earthquake Science
In this study, the shear-wave splitting parameters of local seismic events from the source regions of the 2023 Türkiye MW7.7 and MW7.6 doublet earthquakes (event 1 and event 2, respectively) were measured from June 1, 2022, to April 25, 2023, and their ...

Shear-Wave Splitting in a Critical Crust: the Next Step Biréfringence des ondes transversales dans les croûtes critiques : la prochaine étape

Oil & Gas Science and Technology, 2006
Arguably, shear-wave splitting displaying azimuthal anisotropy has not lived up to its initial promise of opening a new window for understanding cracks and stress in the crust.

Gravitational-wave implications for structure formation: A second-order approach

, 2016
Gravitational waves are propagating undulations in the spacetime fabric, which interact very weakly with their environment. In cosmology, gravitational-wave distortions are produced by most of the inflationary scenarios and their anticipated detection ...

Feasibility of Deep Learning in Shear Wave Splitting analysis using Synthetic-Data Training and Waveform Deconvolution

Seismica
Teleseismic shear-wave splitting analyses are often performed by reversing the splitting process through the application of frequency- or time-domain operations aimed at minimizing the transverse-component energy of waveforms.

Tensor Perturbations in Anisotropically Curved Cosmologies

, 2017
Besides expanding anisotropically, the universe can also be anisotropic at the level of its (spatial) curvature. In particular, models with anisotropic curvature and isotropic expansion leads both to a $\Lambda$CDM-like phenomenology and to an isotropic ...

Effect of Al on the sharpness of the MgSiO_3 perovskite to post-perovskite phase transition [PDF]

, 2005
By means of static ab-initio computations we investigate the influence of Al on the recently discovered perovskite to post-perovskite phase transition in MgSiO_3. We examine three substitution mechanisms for Al in the two structures: MgSi → AlAl; SiSiO →
