Long-term variations in the geomagnetic activity level Part II: Ascending phases of sunspot cycles [PDF]

open access: yesAnnales Geophysicae, 1994
Monthly averages of the Helsinki Ak-values have been reduced to the equivalent aa-indices to extend the aa-data set back to 1844. A periodicity of about five cycles was found for the correlation coefficient (r) between geomagnetic indices and sunspot ...

Unveiling Otolith Mystery: Contemporary Testing Approaches and Their Clinical Significance

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective Otolith is a critical component of the peripheral vestibular system responsible for detecting linear acceleration. Dysfunction of the otolith organs can lead to vertigo, balance disturbances, and gaze instability. By elucidating the physiological foundations and evaluating both current and emerging methods for assessing otolith ...

The Functional Role and Molecular Characterization of the Therapeutic Target CLDN6 in Germ Cell Tumors

open access: yesAndrology, EarlyView.
ABSTRACT Background The tight junction protein CLDN6 has been identified as a cancer‐associated cell surface marker that is rarely expressed in healthy tissues. In testicular germ cell tumors (GCT), CLDN6 is particularly detectable in seminomas, embryonal carcinomas, and choriocarcinomas.

Forecasting long-term sunspot numbers using the LSTM-WGAN model

open access: yesFrontiers in Astronomy and Space Sciences
The sunspot number, an indicator of solar activity, is vital for forecasting variations in solar activity and predicting disturbances of the geomagnetic field.

The new Sunspot Number: assembling all corrections [PDF]

open access: yes, 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

A systematic approach to standardizing the visual appearance of endometriotic lesions for artificial intelligence recognition

open access: yesActa Obstetricia et Gynecologica Scandinavica, EarlyView.
A visual ontology of endometriotic lesions designed for artificial intelligence recognition: back to the past to shape the future. This study proposes a standardized visual ontology of endometriosis lesions observed during laparoscopy, based on a systematic search of the literature.

Solar Cycle Prediction Using a Temporal Convolutional Network Deep-learning Model with a One-step Pattern

open access: yesThe Astrophysical Journal Supplement Series
The 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.

Calibration of Sunspot Numbers

open access: yes, 2010
Waldmeier [1971] found a very tight relationship between the F10.7 solar radio flux and the sunspot number and suggested using the flux for an objective calibration of the sunspot number. He suggested that if this relationship changed later on, the sunspot number should be re-calibrated, assuming that the calibration must have drifted with time.

Welfare Gains and Losses in Sunspot Equilibria [PDF]

open access: yes
We study a standard two period exchange economy with one nominal asset. As is well known there is a continuum of sunspot equilibria around each efficient equilibrium.

Speculative attacks : unique sunspot equilibrium and transparency [PDF]

open access: yes, 2005
Models with multiple equilibria are a popular way to explain currency attacks. Morris and Shin (1998) have shown that, in the context of those models, unique equilibria may prevail once noisy private information is introduced.
