The origin and dynamic interaction of solar magnetic fields [PDF]
, 2007 The dynamics of the solar corona are dominated by the magnetic field which creates its structure. The magnetic field in most of the corona is ‘frozen’ to the plasma very effectively.

A Compact Spin‐Coated Graphene UWB Antenna for Breast Tumor Detection
Advanced Engineering Materials, EarlyView.A compact, spin‐coated graphene ultra‐wideband patch antenna designed for breast tumor detection, capable of distinguishing between malignant and benign tumors. This innovative antenna can serve as an effective initial screening tool, particularly in resource‐limited settings such as rural areas, where access to advanced medical equipment like MRI and ...

Anisotropic Magnetized Asteroseismic Waves
The Astrophysical JournalWe solve for waves in a polytropic, stratified plasma with a spatially varying background magnetic field that points along the horizontal x -direction, and with gravity that is directed along the vertical z -direction.

Two-dimensional numerical experiments of convection.
, 1996 PhDI report the results of numerical studies of 2-dimensional fully compressible convection of a fluid in which the dependence of the radiative conductivity on temperature T is taken as K, (V + aT -5)1 so that central regions of the layer are unstable ...

Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies
Advanced Engineering Materials, EarlyView.Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...

Testing the Rossby Paradigm: Weakened Magnetic Braking in Early K-type Stars
The Astrophysical JournalThere is an intricate relationship between the organization of large-scale magnetic fields by a stellar dynamo and the rate of angular momentum loss due to magnetized stellar winds. An essential ingredient for the operation of a large-scale dynamo is the

The Role of Magnetic Fields in Setting the Star Formation Rate and the Initial Mass Function
Frontiers in Astronomy and Space Sciences, 2019 Star-forming gas clouds are strongly magnetized, and their ionization fractions are high enough to place them close to the regime of ideal magnetohydrodyamics on all but the smallest size scales.

Equilibria and oscillations of magnetised neutron stars
, 2010 We investigate equilibrium configurations and oscillation spectra of neutron stars,modelled as rotating magnetised fluid bodies in Newtonian gravity. We also explorethe idea that these model neutron stars could have dynamics analogous to rigid-bodyfree ...

Rotation and Magnetic Fields: the Evil Twins of Stellar Evolution
, 2006 In this paper I give an overview of the numerous ways in which rotation and magnetic fields can interact under stellar interior conditions. I first provide “tutorial” examples of how magnetic fields can (1) alter existing stellar internal flows, (2 ...
