Influence of solar activity on the phase of the received signal VLF range

Физика волновых процессов и радиотехнические системы, 2019
The effect of sunspots in the 21 cycle of solar activity on the phase of the received signal on two paths and different frequencies is considered. Experimental data were obtained from the phase of the signals received by the Omega radio navigation system.

Long‐term follow‐up of chronic central serous chorioretinopathy patients receiving oral eplerenone and half‐dose photodynamic therapy in the SPECTRA trial: SPECTRA trial report No. 4

Acta Ophthalmologica, EarlyView.
Abstract Purpose Assessing the 24‐month treatment outcome of half‐dose photodynamic therapy (PDT) or oral eplerenone in chronic central serous chorioretinopathy (cCSC). Methods Multicentre randomized clinical trial included cCSC patients from the SPECTRA trial who were randomized to receive half‐dose PDT or oral eplerenone.

The impact of systemic long‐term medications for the development of age‐related macular degeneration

Acta Ophthalmologica, EarlyView.
Abstract Purpose Age‐related macular degeneration (AMD) is a leading cause of central vision loss in the elderly; however, the systemic factors that modulate its incidence and progression remain unclear. We sought to determine whether long‐term use of systemic medications, including diabetes and antithrombotic medications, corticosteroids and ...

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.

Ultrasound, PET/CT or temporal artery biopsy for giant cell arteritis? A prospective diagnostic accuracy study (the GAME‐study)

Acta Ophthalmologica, EarlyView.
Abstract Purpose To investigate the diagnostic performance of ultrasound, 2‐deoxy‐2‐[18F]fluoro‐D‐glucose positron emission tomography/computed tomography (2‐[18F]FDG PET/CT) and temporal artery biopsy (TAB) in giant cell arteritis (GCA). Methods This was a prospective single‐centre diagnostic accuracy study (ClinicalTrials.gov NCT05248906).

The impacts of high refractive errors on self‐reported visual function and visual concern

Acta Ophthalmologica, EarlyView.
Abstract Purpose To examine the association between refractive errors and self‐reported visual function and visual concern, considering self‐perceived present eyesight, concerns about vision, accomplishing less and limitations in daily activities in an eye‐healthy cohort.

Sunspots do matter: a simple disproof of Mas-Colell [PDF]

Mas-Colell conjectured that, for economies admitting a unique deterministic equilibrium, sunspot equilibria that 'matter'' would not exist.

Correlations between sunspots and their moat flows [PDF]

, 2013
Context. The presence of the moat flow around sunspots is intimately linked to the mere existence of sunspots. Aims. We characterize the moat flow (MF) and Evershed flow (EF) in sunspots to enhance our knowledge of sunspot ...

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
