The solar interior [PDF]

, 2009
The sun being the nearest star, provides us a unique opportunity to study stellar processes in sufficient detail to test theories of stellar structure and evolution.

Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

Advanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

Effects of Density Stratification on Rossby Waves in Deep Atmospheres

The Astrophysical Journal
Though Rossby waves have been observed on the Sun, their radial eigenfunctions remain a mystery. Prior theoretical work either considers quasi-2D systems, which do not apply to the solar interior, or only considers fully radiative or fully convective ...

Acoustic wave propagation in the solar sub-photosphere with localised magnetic field concentration: effect of magnetic tension [PDF]

, 2009
Aims: We analyse numerically the propagation and dispersion of acoustic waves in the solar-like sub-photosphere with localised non-uniform magnetic field concentrations, mimicking sunspots with various representative magnetic field configurations ...

Genetic Algorithm for Inferring Model Parameters for Flux Transport Dynamo Simulation

The Astrophysical Journal
The Sun exhibits an 11 yr cyclic variation, maintained by dynamo action in the solar interior. Mean-field flux transport dynamo models have successfully reproduced most of the features observed in solar cycles, while the model includes many free ...

Design of optimal transfers between North and South Pole-sitter orbits [PDF]

, 2012
Recent studies have shown the feasibility of an Earth pole-sitter mission, where a spacecraft follows the Earth’s polar axis to have a continuous, hemispherical view of one of the Earth’s Poles.

Weaving Intelligence: Thermally Drawn Multimaterial Fibers Toward AI‐Enabled Smart Textiles

Advanced Materials, EarlyView.
Thermally drawn multimaterial fibers are rapidly advancing as intelligent structural units for next‐generation smart textiles. Integrating multimaterial architectures with neuromorphic and spiking‐neural‐network principles enables fabrics that can sense, compute, and adapt autonomously.
