Remote Magnetomechanical Neuromodulation Uncovers Therapeutic Mechanisms for Alleviating Parkinsonian Symptoms in Freely Moving Mice

Advanced Science, EarlyView.
Magnetomechanical neuromodulation using magnetic nanodiscs enables remote activation of neurons. In a hemiparkinsonian mouse model, alternating magnetic fields actuate the nanodiscs to generate torque that opens mechanosensitive ion channels within the subthalamic nucleus, thereby modulating basal ganglia motor circuitry.

Thermodynamic Evolution of Plumes

The Astrophysical Journal
Plumes are considered to play an important role in the origin of the solar wind. However, an understanding of their thermodynamic evolution is not complete. Here, we perform a detailed study of a plume inside a coronal hole throughout its lifetime, using

The Solar Minimum Eclipse of 2019 July 2. III. Inferring the Coronal T e with a Radiative Differential Emission Measure Inversion

The Astrophysical Journal, 2023
Differential emission measure (DEM) inversion methods use the brightness of a set of emission lines to infer the line-of-sight (LOS) distribution of the electron temperature ( T _e ) in the corona.

Effects of different coronal hole geometries on simulations of the interaction between coronal waves and coronal holes

Astronomy & Astrophysics
The geometry of a coronal hole (CH) affects the density profile of the reflected part of an incoming global coronal wave (CW). In this study, we perform for the first time magnetohydrodynamic (MHD) simulations of fast-mode MHD waves that interact with CHs of different geometries, such as circular, elliptic, convex, and concave shapes.

Solid Ethanol as a Renewable, Low‐Toxicity, Electron‐Beam Direct Write, and Biomedical Material

Advanced Science, EarlyView.
3D ice lithography (3DIL) enables the fabrication of intricate submicrometer objects using ethanol as a renewable starting material. This study combines process optimization, structural and material analysis, and biomedical applications, from cell culture scaffolds to the patterning of neurostimulation electrodes, demonstrating performance in both in ...

Validation of Long-term Solar Coronal Modeling Using FORWARD

The Astrophysical Journal Supplement Series
This research aims to evaluate the capabilities of two of the most widely used coronal models over multiple solar cycles and to study variations in solar coronal structures over an extended period across multiple channels. We have created a comprehensive

The Nature of Solar Polar Rays [PDF]

, 2000
We use time series observations from the SOHO and Yohkoh spacecraft to study solar polar rays. Contrary to our expectations, we find that the rays are associated with active regions on the sun and are not features of the polar coronal holes.

The influence of different coronal hole geometries on simulations of coronal wave -- coronal hole interaction

The geometry of a coronal hole (CH) affects the density profile of the reflected part of an incoming global coronal wave (CW). In this study, we perform for the first time magnetohydrodynamic (MHD) simulations of fast-mode MHD waves interacting with CHs of different geometries, such as circular, elliptic, convex, and concave shapes.

DIPOLAR EVOLUTION IN A CORONAL HOLE REGION [PDF]

The Astrophysical Journal, 2009
Using observations from the SOHO, STEREO and Hinode, we investigate magnetic field evolution in an equatorial coronal hole region. Two dipoles emerge one by one. The negative element of the first dipole disappears due to the interaction with the positive element of the second dipole. During this process, a jet and a plasma eruption are observed.

Atomic Layer Deposition of Disordered p‐Type SnO Using a Heteroleptic Tin(II) Precursor: Influence of Disorder on P‐Channel SnO Thin‐Film Transistor Characteristics

Advanced Electronic Materials, EarlyView.
Disordered p‐type SnO thin‐films are deposited via atomic layer deposition using a novel heteroleptic precursor. These films enable low‐temperature fabrication of thin‐film transistors with excellent stability and mobility. Their potential compatibility with flexible substrates and integration with n‐type IGZO transistors makes them candidates for ...
