Acta Ophthalmologica, EarlyView.Abstract Purpose To assess the risk of subretinal fluid (SRF) development in the fellow eye of chronic central serous chorioretinopathy (cCSC) patients with unilateral SRF at baseline. Methods Medical records of 334 presumed cCSC patients were retrospectively reviewed.

The Astrophysical Journal Supplement SeriesThe human living environment is influenced by intense solar activity that exhibits periodicity and regularity. Although many deep-learning models are currently used for solar cycle prediction, most of them are based on a multistep pattern.

Time series modelling of sunspot numbers using long range cyclical dependence [PDF]
This paper deals with the analysis of the monthly structure of sunspot numbers using a new technique based on cyclical long range dependence. The results show that sunspot numbers have a periodicity of 130 months, but more importantly, that the series is

The new Sunspot Number: assembling all corrections
, 2015 The Sunspot Number, created by R.Wolf in 1849, provides a direct long-term record of solar activity from 1700 to the present. In spite of its central role in multiple studies of the solar dynamo and of the past Sun-Earth relations, it was never submitted

The oscillatory response of the electroretinogram and neuronal adaptation
Acta Ophthalmologica, EarlyView.Abstract After more than 50 years, there still remains a challenge and an interest to know more as well as extend and deepen our understanding of the small rapid wavelets, the oscillatory potentials (OPs), of the electroretinogram (ERG) and the neuronal adaptation of the retina.

Recurrent magnetic activity, sunspot number and its rate of decline
, 1974 Power spectral densities computed from low-latitude horizontal intensity of the Earth's magnetic field over two-year periods of declining phases of solar cycles 16 to 19 show a close relationship with the maximum relative sunspot number of the following ...

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.

Tests of sunspot number sequences: 1. Using ionosonde data
, 2016 More than 70 years ago it was recognised that ionospheric F2-layer critical frequencies [foF2] had a strong relationship to sunspot number. Using historic datasets from the Slough and Washington ionosondes, we evaluate the best statistical fits of foF2 ...

Tests of sunspot number sequences: 2. Using geomagnetic and auroral data [PDF]
, 2016 We compare four sunspot-number data sequences against geomagnetic and terrestrial auroral observations. The comparisons are made for the original SIDC (Solar Influences Data Center) composite of Wolf/Zürich/International sunspot number [RISNv1], the ...
