Assimilation of Earth rotation parameters into a global ocean model: excitation of polar motion [PDF]

open access: yesNonlinear Processes in Geophysics, 2011
The oceanic contribution to Earth rotation anomalies can be manifold. Possible causes are a change of total ocean mass, changes in current speed or location and changes in mass distribution.

The Lorentz force in atmospheres of CP stars: $\theta$ Aurigae [PDF]

open access: yes, 2006
Several dynamical processes may induce considerable electric currents in the atmospheres of magnetic chemically peculiar (CP) stars. The Lorentz force, which results from the interaction between the magnetic field and the induced currents, modifies the ...

Analysis of Local and Global Aromaticity in Si3C5 and Si4C8 Clusters. Aromatic Species Containing Planar Tetracoordinate Carbon

open access: yesChemistry, 2021
The minimum energy structures of the Si3C5 and Si4C8 clusters are planar and contain planar tetracoordinate carbons (ptCs). These species have been classified, qualitatively, as global (π) and local (σ) aromatics according to the adaptive natural density

Current trends in scientific research on global warming: a bibliometric analysis

open access: yesInternational Journal of Global Warming, 2019
The objective of this paper is to contribute to a better understanding of the scientific knowledge in global warming, as well as to investigate the evolution of the research knowledge through the published papers included in Web of Science database. A bibliometric and social network analyses was performed to obtain indicators of scientific productivity,

Evolution and current state of global research on paediatric resuscitation: a systematic scientometric analysis [PDF]

open access: yesScandinavian Journal of Trauma, Resuscitation and Emergency Medicine, 2020
Abstract Background Paediatric resuscitation is rare but potentially associated with maximal lifetime reduction. Notably, several nations experience high infant mortality rates even today. To improve clinical outcomes and promote research, detailed analyses on evolution and current state of ...

Globalization and sovereignty decline: Regionalization problem in Serbia within the actual geopolitical context [PDF]

open access: yesSociološki Pregled, 2002
In the article author is about to maintain that discussion on regionalization asks for contextualisation within the currents of actual geopolitics, on the one hand, and wider process of globalisation and unification, on the other.

Assessing the impact of multiple altimeter missions and Argo in a global eddy-permitting data assimilation system [PDF]

open access: yesOcean Science, 2017
A series of observing system simulation experiments (OSSEs) is carried out with a global data assimilation system at 1∕4° resolution using simulated data derived from a 1∕12° resolution free-run simulation.

SF6 High-Voltage Circuit Breaker Contact Status Detection at Different Currents

open access: yesSensors, 2022
Currently, the online non-destructive testing (NDT) methods to measure the contact states of high-voltage circuit breakers (HVCBs) with SF6 gas as a quenching medium are lacking.

Deformations of vector-scalar models [PDF]

open access: yes, 2018
Abelian vector fields non-minimally coupled to uncharged scalar fields arise in many contexts. We investigate here through algebraic methods their consistent deformations ("gaugings"), i.e., the deformations that preserve the number (but not necessarily ...

Comparison of Birkeland current observations during two magnetic cloud events with MHD simulations [PDF]

open access: yesAnnales Geophysicae, 2008
Low altitude field-aligned current densities obtained from global magnetospheric simulations are compared with two-dimensional distributions of Birkeland currents at the topside ionosphere derived from magnetic field observations by the constellation ...
