Thermodynamic Evolution of Plumes

open access: yesThe 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

open access: yesThe 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.

Bioadhesive‐Integrated 3D‐Printed Multilayer Scaffolds Secure a Mechanically‐Stable Osteoimmune Niche for Enhanced Bone Augmentation

open access: yesAdvanced Science, EarlyView.
A 3D‑printed multilayer adhesive scaffold, firmly anchored to bone defects by simple finger pressing, suppresses micromotion and secures mechanical stability of the osteogenic niche. This stabilization likely contributes to the enhanced bone augmentation by fostering a pro‑regenerative mechano‐immune profile—characterized by M2‑like macrophage ...

Validation of Long-term Solar Coronal Modeling Using FORWARD

open access: yesThe 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

Extracellular CIRP Dysregulates Microglial Efferocytosis in Acute Ischemic Stroke via the TLR4/miR‐155/MafB Axis

open access: yesAdvanced Science, EarlyView.
eCIRP released in the stroke brain binds to TLR4 expressed on microglia to induce miR‐155, which suppresses MafB, decreases MerTK and downstream signaling to impair efferocytosis of apoptotic neurons, worsening the acute stroke outcomes. Inhibition of eCIRP‐TLR4 interaction with small peptide C23 attenuates eCIRP‐induced microglial efferocytic ...

Responses of a Coronal Hole to a Fast Flare-driven Coronal Wave

open access: yesThe Astrophysical Journal Letters
Abstract Coronal waves, significant solar phenomena, act as diagnostic tools for scientists studying solar atmosphere properties. Here, we present a novel observation detailing how a coronal wave event, associated with an X5.0 class flare, influenced the properties of an adjacent coronal hole (CH) through interaction.

A Multiscale Mechanistic Framework for Polydopamine Dyeing in Ultrablack Wool Textiles

open access: yesAdvanced Science, EarlyView.
Ultrablack photonic textiles are enabled through polydopamine (PDA) dyeing, which is governed by the interplay of PDA chemistry, wool surface topology and chemistry, and hierarchical fiber–yarn–fabric architecture. Fabric architecture emerges as a primary and previously underappreciated design lever for wide‐angle optical performance.

Estimating the Poynting Flux of Alfvénic Waves in Polar Coronal Holes across Solar Cycle 24

open access: yesThe Astrophysical Journal
Alfvénic waves are known to be prevalent throughout the corona and solar wind. Determining the Poynting flux supplied by the waves is required for constraining their role in plasma heating and acceleration, as well as providing a constraint for Alfvén ...

Nrsn1–Smarcc1 Coupling Regulates Neural Stem Cell Differentiation and Chronic‐phase Recovery After Ischemic Stroke

open access: yesAdvanced Science, EarlyView.
In the post‐stroke brain, Foxa2 induces the transcriptional upregulation of Nrsn1 in NSCs. Nrsn1 functionally couples with Smarcc1, modulating its nuclear availability and protein abundance, thereby influencing Smarcc1‐associated regulatory programs linked to neuronal lineage commitment. Through this coupling, Nrsn1 promotes the differentiation of NSCs

Coronal holes and prediction of recurrent high-velocity streams [PDF]

open access: yes, 1988
По данным за 1973—1979 гг. изучены связи между крупномасштабным магнитным полем Солнца (КМПС), корональными дырами (КД), секторными структурами межпланетного магнитного поля (СС ММП) и высокоскоростными потоками (ВСП) с использованием ...
