Coronal heating by surface Alfvén wave damping: Implementation in a global magnetohydrodynamics model of the solar wind
(IOP Publishing, 2012-09)
The heating and acceleration of the solar wind is an active area of research. Alfvén waves, because of their ability to accelerate and heat the plasma, are a likely candidate in both processes. Many models have explored ...
Polar caps during geomagnetic polarity reversals
(Wiley Blackwell Publishing, Inc, 2019-02)
Changes in the Earth’s magnetic field can deeply modify the polar caps and auroral zones, which are the regions of most frequent precipitation of energetic particles. The present field is characterized by a dominant dipole ...
Single Field Inflation and non-Gaussianity
(American Physical Society, 2002-12)
We study non-Gaussian signatures on the cosmic microwave background (CMB) radiation predicted within inflationary models with non-vacuum initial states for cosmological perturbations. The model incorporates a privileged ...
Dynamical Casimir effect in a double tunable superconducting circuit
(American Physical Society, 2018-08)
We present an analytical and numerical analysis of the particle creation in a cavity ended with two superconducting quantum interference devices, both subjected to time-dependent magnetic fields. In the linear and lossless ...
Density and Thermal Structure of the Southern Andes and Adjacent Foreland from 32° to 55°S Using Earth Gravity Field Models
(Springer Earth System Sciences, 2016-01)
GOCE satellite data and EGM2008 model are used to calculate the gravity anomaly and its vertical gravity gradient, both corrected by the topographic effect, in order to delineate main tectonic features related to density ...
Ring currents modulate optoelectronic properties of aromatic chromophores at 25 T
(National Academy of Sciences, 2020-05)
The properties of organic molecules can be influenced by magnetic fields, and these magnetic field effects are diverse. They range from inducing nuclear Zeeman splitting for structural determination in NMR spectroscopy to ...
Crystalline electrical field effects on powdered RE Cu4Al8 (RE = Tb, Dy, Ho and Er) intermetallic compounds
(Elsevier, 2021-03)
In this work, structural and magnetic properties RE Cu4Al8 (RE = Tb, Dy, Ho and Er) family of compounds are reported. Measurements of X-ray diffraction, tem- perature (T) and magnetic eld (H) dependencies of magnetization ...
Optimization of reactive extraction of C1–C4 aliphatic monocarboxylic acids from aqueous solutions: modeling solvation effect with extended-LSER, A-UNIFAC and SPR
(John Wiley & Sons Ltd, 2017-11)
This paper studies reactive extraction of formic (FA), acetic (AA), propionic (PA) and butyric (BA) acids from aqueous solutions by tri-n-butyl amine/diluent, with particular focus on proper optimization and modeling of ...
Magnetization plateaus and jumps in a frustrated four-leg spin tube under a magnetic field
(American Physical Society, 2014-11)
We study the ground state phase diagram of a frustrated spin-1/2 four-leg spin tube in an external magnetic field. We explore the parameter space of this model in the regime of all-antiferromagnetic exchange couplings by ...
Alternating regimes of motion in a model with cell-cell interactions
(American Physical Society, 2020-06)
Cellular movement is a complex dynamic process, resulting from the interaction of multiple elements at the intra-and extracellular levels. This epiphenomenon presents a variety of behaviors, which can include normal and ...
