Structure of solar coronal loops: from miniature to large-scale [PDF]

, 2013
Aims. We use new data from the High-resolution Coronal Imager (Hi-C) with its unprecedented spatial resolution of the solar corona to investigate the structure of coronal loops down to 0.2′′. Methods. During a rocket flight, Hi-C provided images

Printing‐Assisted Integration of Thermal, Fluidic and Electrical Components in Implants for Focal Brain Cooling

Advanced Science, EarlyView.
Extrusion‐based 3D printing of silicones and discrete electronic components are combined to create cortical implants for rodents that integrate thermal neuromodulation and electrical recording. Linked to an autonomous auxiliary driver unit, the system enables rapid, stable and localized hypothermia alongside ECoG recording.

TRANSVERSE OSCILLATIONS OF A COOLING CORONAL LOOP

The Astrophysical Journal, 2009
Here we present an investigation into how cooling of the plasma influences the oscillation properties (e.g., eigenfunctions and eigenfrequencies) of transverse (i.e., kink) magnetohydrodynamic (MHD) waves in a compressible magnetic flux tube embedded in a gravitationally stratified and uniformly magnetized atmosphere.

Coronal Condensations Caused by Magnetic Reconnection between Solar Coronal Loops

, 2018
Employing Solar Dynamics Observatory/Atmospheric Imaging Assembly (AIA) multi-wavelength images, we report the coronal condensation during the magnetic reconnection (MR) between a system of open and closed coronal loops.

The cooling of coronal plasmas. IV. Catastrophic cooling of loops [PDF]

, 2013
We examine the radiative cooling of coronal loops and demonstrate that the recently identified catastrophic cooling is due to the inability of a loop to sustain radiative/enthalpy cooling below a critical temperature, which can be >1 MK in flares, 0.5-1 ...

A Gut‐Brain Axis Underlying Succinate‐Associated Compulsive‐Like Behavior

Advanced Science, EarlyView.
Gut‐derived succinate is associated with an excitatory‐inhibitory imbalance in dmPFC glutamatergic neurons, involving microglial SUCNR1 activation and vagal afferent signaling via upregulated gut 5‐HT4 receptors along the DVC‐CeA‐dmPFC circuit, changes that are linked to excessive compulsive‐like behavior.

Magnetic Topology and Loop Statistics in Observed Coronal Holes Using Potential Field Modeling

The Astrophysical Journal
Potential field source surface (PFSS) models are widely used to study the solar corona and form the basis for solar wind forecasting, yet they often fail to reproduce observed properties of coronal holes.

Persistent Zn2+ Influx‐Mediated Deacetylation of ANXA2 Regulates the “Zn2+‐Autophagic Flux” and Alleviates Intervertebral Disc Degeneration

Advanced Science, EarlyView.
Zinc transporter SLC39A14 sustains intracellular Zn2+ levels to activate SIRT3‑dependent ANXA2 deacetylation at K302. This modification weakens ANXA2‑mTOR binding and releases autophagic‑flux suppression in nucleus pulposus cells. Dysregulated Zn2+ homeostasis disrupts this axis to drive intervertebral disc degeneration.

On the Connection of Coronal Loop Plasma with the Ambient Magnetic Field

The Astrophysical Journal Letters
Solar coronal loops are magnetically confined plasma structures whose properties are closely linked to the ambient magnetic field. Using 3D magnetohydrodynamic simulations of kink-unstable coronal flux tubes, we investigate how the intensity of the ...

Asymmetric twisting of coronal loops [PDF]

The bright solar corona entirely consists of closed magnetic loops rooted in the photosphere. Photospheric motions are important drivers of magnetic stressing which eventually leads to energy release into heat.
