Probing Velocity Dispersion Inside Coronal Mass Ejections: New Insights on Their Initiation

The Astrophysical Journal Letters
This work studies the kinematics of the leading edge and the core of six coronal mass ejections (CMEs) in the combined field of view of Sun Watcher using Active Pixel System detector and Image Processing (SWAP) on board PRoject for On-Board Autonomy ...

Model‐Based Analysis of Ionospheric TEC Disturbances Over China and Adjacent Regions During the May 2024 Super Geomagnetic Storm

Space Weather, Volume 24, Issue 8, August 2026.
Abstract This study uses observation data from multi‐constellation (GPS/GLONASS/Galileo/BeiDou) ground‐based Global Navigation Satellite Systems (GNSS) networks and a non‐integrated spherical harmonic function modeling methodology to develop an ionospheric Total Electron Content (TEC) model with high spatiotemporal resolution (1° × 1° in longitude and ...

Ambulatory Blood Pressure Characteristics and Target Organ Effects in Hypertensive Children With Renal Artery Variations

The Journal of Clinical Hypertension, Volume 28, Issue 8, August 2026.
ABSTRACT Renal artery variations are recognized as potential contributors to hypertension through altered renal perfusion and activation of renin–angiotensin system. However, their clinical and hemodynamic significance in children remains unclear. This retrospective study included 14 pediatric patients (0–18 years) with hypertension and renal artery ...

Understanding the Evolution of the Three-part Structure of a Coronal Mass Ejection Using Multiviewpoint Observations

The Astrophysical Journal
The three-part structure (bright front, dark cavity, and bright core) of coronal mass ejections (CMEs) in white-light (WL) coronagraphic images has been studied for decades.

Regarding the detectability and measurement of coronal mass ejections

Journal of Space Weather and Space Climate, 2015
In this review I discuss the problems associated with the detection and measurement of coronal mass ejections (CMEs). CMEs are important phenomena both scientifically, as they play a crucial role in the evolution of the solar corona, and technologically,

Can acromegaly be controlled in all cases?

Journal of Neuroendocrinology, Volume 38, Issue 8, August 2026.
Abstract Acromegaly is a rare disease, due in most of the cases to a growth hormone (GH)‐secreting pituitary adenoma (PA), namely neuroendocrine tumour (PitNET). The treatment of patients with acromegaly is multimodal and multi‐step, including surgery, medical therapies, and radiotherapy.

Automated Detection of Coronal Mass Ejections with Few-shot Learning

The Astrophysical Journal Supplement Series
Coronal mass ejections (CMEs) are a primary driver of severe space weather impacts, yet accurate delineation of CME structure in coronagraph images remains challenging.

Nanoscale space weathering features in mature lunar soil revealed by TEM and APT

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 2048-2072, August 2026.
Abstract Space weathering significantly alters the optical, chemical, and structural properties of lunar regolith at micro‐ and nanoscales; yet detailed nanoscale variability within individual soils remains underexplored. Here we apply transmission electron microscopy (TEM) and atom probe tomography to four mineral grains (olivine, ilmenite, and two ...

Narrow Coronal Mass Ejections

The Astrophysical Journal, 2001
Narrow coronal mass ejections (CMEs), defined arbitrarily as events whose apparent angular width is 15° or less, are a small subset of all CMEs. Little is known of the properties of these events and whether these properties differ from those of the larger, more typical CMEs. We have included in this study 15 narrow CMEs observed in the period from 1999

Prediabetic cardiomyopathy is attenuated by hypothalamic PVN oxytocin neuron activation

The Journal of Physiology, Volume 604, Issue 16, Page 6872-6894, 15 August 2026.
Abstract figure legend A long‐term high‐fat, high‐fructose diet induces prediabetes with insulin resistance, hyperinsulinaemia, elevated triglycerides and metabolic‐associated steatotic liver disease (MASLD) in male rats. Animals developed prediabetic cardiomyopathy characterized by diastolic dysfunction, interstitial fibrosis and tachycardia ...
