THE METASTABLE DYNAMO MODEL OF STELLAR ROTATIONAL EVOLUTION [PDF]
, 2014 This paper introduces a new empirical model for the rotational evolution of Sun-like stars—those with surface convection zones and non-convective interior regions.

Multimodal Layer‐Crossing Interrogation of Brain Circuits Enabled by Microfluidic Axialtrodes
Advanced Science, EarlyView.The study introduces a flexible microfluidic axialtrode that integrates optical, electrical, and chemical modalities within a single polymer fiber. By redistributing electrodes and fluidic channels along the fiber axis via angled cleaving, it enables simultaneous optogenetic stimulation, electrophysiological recording, and drug delivery across brain ...

The Effects of Radially Varying Diffusivities on Stellar Convection Zone Dynamics
The Astrophysical JournalConvection is ubiquitous in stellar and planetary interiors, where it likely plays an integral role in the generation of magnetic fields. As the interiors of these objects remain hidden from direct observation, numerical models of convection are an ...

Advanced Science, EarlyView.Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

Fluid Mixing during Phase Separation in Crystallizing White Dwarfs
The Astrophysical JournalAccurate models of cooling white dwarfs must treat the energy released as their cores crystallize. This phase transition slows the cooling by releasing latent heat and also gravitational energy, which results from phase separation: liquid C is released ...

Anelastic Magnetohydrodynamic Equations for Modeling Solar and Stellar Convection Zones
The Astrophysical Journal Supplement Series, 1999 The anelastic approximation has strong advantages for numerical simulations of stellar and solar convection zones. The chief and generally known one is that it suppresses acoustic modes, permitting larger simulated time steps to be taken than would be possible in a fully compressible model.

On the origin of microturbulence in hot stars
, 2008 We present results from the first extensive study of convection zones in the envelopes of hot massive stars, which are caused by opacity peaks associated with iron and helium ionization.

Advanced Science, EarlyView.A cascade‐responsive MXene@Cu‐MOF/GelMA hydrogel is engineered as a “skeleton–backpack” platform for extensive tracheal repair. The MXene framework scavenges postoperative ROS and converts NIR light into mild hyperthermia, while the Cu‐MOF component provides pH/NIR‐responsive Cu2+ dosing for infection control, angiogenesis, and chondrogenesis.

On the Temporal Variability in the Magnetic Dichotomy of Late M Dwarf Stars
The Astrophysical JournalRapidly rotating late M dwarfs are observed in two different branches of magnetic activity, although they operate in the same stellar parameter range. Current empirical evidence indicates that M dwarfs with spectral types ranging from M3/M4 to late-type ...

Effects of rotation and surface forcing on deep stellar convection zones
Proceedings of the International Astronomical Union, 2023 AbstractThe canonical undestanding of stellar convection has recently been put under doubt due to helioseismic results and global 3D convection simulations. This “convective conundrum” is manifested by much higher velocity amplitudes in simulations at large scales in comparison to helioseismic results, and the difficulty in reproducing the solar ...
