Modeling Viscosity of Volcanic Melts With Artificial Neural Networks
Geochemistry, Geophysics, Geosystems, 2022 Viscosity is of great importance in governing the dynamics of volcanoes, including their eruptive style. The viscosity of a volcanic melt is dominated by temperature and chemical composition, both oxides and water content.

Emplacement of magma pulses and growth of magma bodies [PDF]
Tectonophysics, 2011 Magmatism is responsible for the formation of continental and oceanic crusts. It is the main agent of mass and heat transfers from the mantle towards the crust, the hydrosphere (oceanic and continental hydrothermalism) and the atmosphere (emissions of volcanic gas and ashes).

Seismolosical studies of magma injection processes: volcano monitoring and imaging of magma chambers [PDF]
, 2001 The processes associated with magma injection at shallow depths within the crust have been the topic of many geophysical studies, some investigating the seismicity that accompanies volcanic activity and others attempting to map the subsurface extent and ...

Isolating transdiagnostic effects reveals specific genetic profiles in psychiatric disorders
JCPP Advances, EarlyView.Abstract Background Evidence indicates substantial genetic overlap between psychiatric diagnoses. Accounting for these transdiagnostic effects can sharpen research on disorder‐specific genetic architecture and patterns of comorbidity. Methods We applied genomic structural equation modeling to genome‐wide association study summary statistics from 11 ...

Managing and visualising geochemical data for tephra correlation with the IntChron Integration Tool
Journal of Quaternary Science, EarlyView.ABSTRACT There is now a wealth of glass‐shard geochemical data for volcanic ash (tephra) layers from a wide range of volcanoes and eruptions, providing invaluable datasets for tephrochronology. However, compilation of published data to assess tephra correlations leads to large files and requires careful management.

Peskine Sixfolds and Debarre–Voisin Fourfolds With Associated Cubic Fourfolds
Mathematische Nachrichten, EarlyView.ABSTRACT We develop the notion of Peskine sixfolds with associated K3 surfaces and cubic fourfolds and work out numerical conditions for when these associations occur. In discriminant 24, the first family for which there is an associated cubic fourfold, we identify the cubic explicitly.
