Photospheric magnetic structure of coronal holes

, 2019
In this study, we investigate in detail the photospheric magnetic structure of 98 coronal holes using line-of-sight magnetograms of SDO/HMI, and for a subset of 42 coronal holes using HINODE/SOT G-band filtergrams. We divided the magnetic field maps into

An Injectable Metal‐Drug Supramolecular Condensate Enables Radiosensitization and Systemic Antitumor Immunity for Post‐Surgical Osteosarcoma Therapy

Advanced Science, EarlyView.
This work designed an injectable metal‐drug supramolecular condensate formed from hafnium ions and alendronate (Hf‐ALN) and loaded with the COX‐2 inhibitor celecoxib (CXB) for synergistic radioimmunotherapy of postoperative osteosarcoma. Mechanistically, upon X‐ray irradiation, Hf enhances radiation energy deposition, ROS generation, and DNA damage ...

On the Existence of Long-period Decayless Oscillations in Short Active Region Loops

The Astrophysical Journal
Decayless kink oscillations, characterized by their lack of decay in amplitude, have been detected in coronal loops of varying scales in active regions, the quiet Sun, and coronal holes. Short-period (

A mouse model of mechanical stress injury to the basal ganglia using thermosensitive PNIPAM hydrogel for intracerebral hemorrhage research

Animal Models and Experimental Medicine, EarlyView.
In this study, we established a novel mouse model of intracerebral hemorrhage (ICH) by stereotactically injecting thermosensitive PNIPAM hydrogel into the internal capsule to impose localized mechanical stress on the corticospinal tract, which provides a straightforward and reproducible tool for preclinical studies on focal mechanical stress–induced ...

On the Origin of the Sudden Heliospheric Open Magnetic Flux Enhancement During the 2014 Pole Reversal

The Astrophysical Journal
Coronal holes are recognized as the primary sources of heliospheric open magnetic flux (OMF). However, a noticeable gap exists between in situ measured OMF and that derived from remote-sensing observations of the Sun.

Are subsurface flows and coronal holes related?

, 2012
International audienceWe study synoptic maps of solar subsurface flows covering six Carrington rotations (2050 to 2055). The subsurface flows are determined with a ring-diagram analysis of GONG high-resolution Doppler data.

Non‐contrast CT Markers of Hematoma Expansion and Andexanet Response in Factor Xa Inhibitor‐Associated Intracerebral Hemorrhage: An Analysis from ANNEXa‐I Trial

Annals of Neurology, EarlyView.
In this post hoc analysis of the ANNEXa‐I trial (n = 434), we evaluated non‐contrast computed tomography (NCCT) markers of hematoma expansion (HE) in factor Xa inhibitor (FXai) –associated intracerebral hemorrhage (ICH). At least one NCCT marker was present in 72.1%, and HE (≥12.5 mL or ≥ 35% increase in hematoma volume) occurred in 31.8 ...

Production of 3D printed biomodels of the canine brain for veterinary neuroanatomy teaching

Anatomical Sciences Education, EarlyView.
Abstract Teaching neuroanatomy presents multiple challenges to both students and teachers, as it is a subject with highly dense content that commonly causes the development of aversion by students, a phenomenon referred to as “neurophobia,” which has been documented in human and veterinary medicine students.

What drives solar-EUV jets seen in equatorial coronal holes?

Results in Physics, 2016
Recent observations of jets in solar coronal holes that include multi-wavelength data such as EUV movies have shown that most of those jets are not driven in the way suggested by the standard model.

Development of interactive MRI‐based 3D visualization tools for neuroanatomy education in Latin America

Anatomical Sciences Education, EarlyView.
Abstract The study of neuroanatomy is fundamental in many scientific fields. Despite this, it is a challenging subject for students. As technology evolves, it is being increasingly incorporated into educational methods, including the teaching of neuroanatomy. Three‐dimensional (3D) visualizations are well suited for displaying neuroanatomy.
