Sequential modelling of the Earth’s core magnetic field [PDF]

Earth, Planets and Space, 2020
We describe a new, original approach to the modelling of the Earth’s magnetic field. The overall objective of this study is to reliably render fast variations of the core field and its secular variation.

Gravitational core of double field theory

European Physical Journal C: Particles and Fields
Double Field Theory (DFT) has emerged as a comprehensive framework for gravity, presenting a testable and robust alternative to General Relativity (GR), rooted in the $$\textbf{O}(D,D)$$ O ( D , D ) symmetry principle of string theory.

Real-time temperature field recovery of a heterogeneous reactor based on the results of calculations in a homogeneous core [PDF]

Nuclear Energy and Technology, 2022
Advanced pressurized water reactors are the main part of a new generation of nuclear power plant projects under development that provide cost-effective power production for various needs (Yemelyanov et al. 1982, Klimov 2002, Boyko et al.

Earth's core variability from magnetic and gravity field observations [PDF]

Solid Earth, 2023
The motions of the liquid within the Earth's outer core lead to magnetic field variations together with mass distribution changes. As the core is not accessible for direct observation, our knowledge of the Earth’s liquid core dynamics only relies on ...

Concurrent TMS-fMRI: Technical Challenges, Developments, and Overview of Previous Studies

Frontiers in Psychiatry, 2022
Transcranial magnetic stimulation (TMS) is a promising treatment modality for psychiatric and neurological disorders. Repetitive TMS (rTMS) is widely used for the treatment of psychiatric and neurological diseases, such as depression, motor stroke, and ...

Uludağ Extensional Metamorphic Core Complex: Preliminary Field Observations

Bulletin of the Mineral Research and Exploration, 2022
In the northern margin of Uludağ massif in northwest Anatolia, the Bursa Detachment having top-to-the north, northeast normal sense of shear separates the lower plate high-grade metamorphic rocks of Series-A (Uludağ Group) from the upper plate low-grade ...

Fields and filaments in the core of the Centaurus cluster [PDF]

Monthly Notices of the Royal Astronomical Society, 2007
We present high resolution images of the Faraday Rotation Measure (RM) structure of the radio galaxy PKS 1246-410, at the center of the Centaurus cluster. Comparison with Halpha-line and soft X-ray emission reveals a correspondence between the line-emitting gas, the soft X-ray emitting gas, regions with an excess in the RM images, and signs of ...

Dislocation Core Energies and Core Fields from First Principles [PDF]

Physical Review Letters, 2009
Ab initio calculations in bcc iron show that a <111> screw dislocation induces a short-range dilatation field in addition to the Volterra elastic field. This core field is modeled in anisotropic elastic theory using force dipoles. The elastic modeling thus better reproduces the atom displacements observed in ab initio calculations. Including this

Statistics of Diffusive and Localized Fields in the Vortex Core [PDF]

Physical Review Letters, 2007
The statistics of the field structure in the vortex core surrounding phase singularities in random wave fields are measured and calculated for diffusive and localized waves. Excellent agreement is found between experiment and theory. The variation of phase with geometric angle is deterministic, depending only upon the eccentricity of elliptical ...
