On the Magnetic Nature of Quiet-Sun Chromospheric Grains

The Astrophysical Journal Letters, 2023
Ca ii K grains, i.e., intermittent, short-lived (about 1 minute), periodic (2–4 minutes), pointlike chromospheric brightenings, are considered to be the manifestations of acoustic waves propagating upward from the solar surface and developing into shocks

Ubiquitous quiet-Sun jets [PDF]

Astronomy & Astrophysics, 2011
IMaX/Sunrise has recently reported the temporal evolution of highly dynamic and strongly Doppler shifted Stokes V signals in the quiet Sun. We attempt to identify the same quiet-Sun jets in the Hinode spectropolarimeter (SP) data set. We generate combinations of linear polarization magnetograms with blue- and redshifted far-wing circular polarization ...

Simulating Siberian Radioheliograph response to the quiet Sun

Solar-Terrestrial Physics, 2018
The Siberian Radioheliograph (SRH) correlation plot is the time dependence of the sum of absolute values of complex correlations over all baselines. These plots are built for each operating frequency of SRH.

A 3D‐Printed Vascular‐Like Perfusion Tumor‐on‐a‐Chip Recapitulates High‐Grade Breast Cancer With in Vivo‐Relevant Drug Resistance

Advanced Healthcare Materials, EarlyView.
A high‐resolution 3D‐printed tumor‐on‐a‐chip platform sustains breast cancer tissues at in vivo–like cell densities through vascular‐like perfusion. This engineered system recapitulates grade‐dependent molecular features and exhibits drug‐resistance profiles that uniquely align with clinically relevant Cmax values.

Soft Skins With Reversible Thickness Morphing: Materials, Mechanisms, and Applications

Advanced Materials, EarlyView.
Evolution of electronic skin (e‐skin) technologies toward adaptive, multifunctional soft skins. Phase I highlights early rigid and discrete sensory interfaces. Phase II shows the transition toward flexible, stretchable, and large‐area e‐skin. Phase III captures the emergence of computational e‐skin.

Gene Correction Enhances Dopaminergic Cell Therapy in a Nonhuman Primate Model of Parkinson's Disease

Advanced Science, EarlyView.
LRRK2‐mutant induced pluripotent stem cells (iPSCs) were derived from a patient with Parkinson's disease (PD). Using CRISPR/Cas9–mediated gene editing, the pathogenic LRRK2 mutations were precisely corrected, and isogenic dopaminergic neural progenitor cells (DA‐NPCs) were subsequently generated.
