Harmonizing Sunspot Datasets Consistency: Focusing on SOHO/MDI and SDO/HMI Data

Universe
To ensure the long-term consistency of sunspot group data, it is essential to harmonize measurements from SOHO/MDI and SDO/HMI, two major solar observatories with overlapping coverage.

On connection of variations between hard cosmic ray flux, temperature and cardiovascular diseases in Vilnius and sunspot number during 2001–2012

Journal of Environmental Engineering and Landscape Management, 2015
The connection has been found between the course of cardiovascular diseases (CVD) and the hard cosmic ray flux (HCRF) near the ground surface in Vilnius. The course of air temperature and number of sunspot was simultaneously considered. The investigation

Tubulointerstitial nephritis and uveitis syndrome in children: What to keep an eye on

Acta Ophthalmologica, EarlyView.
Abstract Purpose The purpose of this study was to determine the disease course in patients with tubulointerstitial nephritis and uveitis (TINU) syndrome, focusing on long‐term outcome and the incidence of complications such as chronic kidney disease (CKD).

Image patch analysis of sunspots and active regions. I. Intrinsic dimension and correlation analysis

, 2015
The flare-productivity of an active region is observed to be related to its spatial complexity. Mount Wilson or McIntosh sunspot classifications measure such complexity but in a categorical way, and may therefore not use all the information present in ...

Coronal Mass Ejections from Sunspot and Non-Sunspot Regions [PDF]

, 2009
Coronal mass ejections (CMEs) originate from closed magnetic field regions on the Sun, which are active regions and quiescent filament regions. The energetic populations such as halo CMEs, CMEs associated with magnetic clouds, geoeffective CMEs, CMEs associated with solar energetic particles and interplanetary type II radio bursts, and shock-driving ...

Characterizing and assessing vision‐related quality of life among patients discontinued treatment for neovascular age‐related macular degeneration

Acta Ophthalmologica, EarlyView.
Abstract Purpose This study characterized and assessed vision‐related quality of life (VRQoL) in patients with neovascular age‐related macular degeneration (nAMD) who discontinued treatment with intravitreal anti‐vascular endothelial growth factor (anti‐VEGF), comparing them to those undergoing treatment.

The Extended Solar Cycle: Muddying the Waters of Solar/Stellar Dynamo Modeling or Providing Crucial Observational Constraints?

Frontiers in Astronomy and Space Sciences, 2018
In 1844 Schwabe discovered that the number of sunspots increased and decreased over a period of about 11 years, that variation became known as the sunspot cycle.

Bimodal Distribution of Area-Weighted Latitude of Sunspots And Solar North-South Asymmetry

, 2011
We study the latitudinal distribution of sunspots observed from 1874 to 2009 using the center-of-latitude (COL). We calculate COL by taking the area-weighted mean latitude of sunspots for each calendar month.

Seasonal variation in the incidence of central serous chorioretinopathy: A systematic review and meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract Central serous chorioretinopathy (CSC) is a chorioretinal disease characterised by serous subretinal fluid (SRF) in the macula, resulting in sudden central vision loss. It predominantly affects working‐age adults, particularly men aged 30 to 60 years.

Evaluation of the capability of local helioseismology to discern between monolithic and spaghetti sunspot models

, 2014
The helioseismic properties of the wave scattering generated by monolithic and spaghetti sunspots are analyzed by means of numerical simulations. In these computations, an incident f or p1 mode travels through the sunspot model, which produces absorption
