Nonlinear three-dimensional magnetoconvection around magnetic flux tubes [PDF]

, 2011
Magnetic flux in the solar photosphere forms concentrations from small scales, such as flux elements, to large scales, such as sunspots. This paper presents a study of the decay process of large magnetic flux tubes, such as sunspots, on a supergranular ...

Unveiling Otolith Mystery: Contemporary Testing Approaches and Their Clinical Significance

World 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 ...

Modern View of the Sun: Materials for an Experimental History at the Dawn of the Telescopic Era

Histories
Galileo and the telescope revolutionized the concept of the Sun. The discovery of its rotation was possible due to the continuous observation of the sunspots. The faculae and the maculae with umbra and penumbra became accessible daily to new instruments,

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

Andrology, 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.

Rotating Sunspots and Solar Eruptions

, 2012
In this presentation, we first introduced the definition and classification of rotating sunspots. Using multi-wavelength data, we investigated the evolution of some rotating sunspots and the response of upper atmosphere relevant to the rotating sunspots.

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

Acta 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.

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.

The Making of Delta Sunspots

The Astrophysical Journal
We explore what fraction of delta sunspots with a sharp polarity inversion line (PIL) in photospheric magnetograms are produced by a writhe kink in an emerging twisted flux rope.

Technique for Automated Recognition of Sunspots on Full-Disk Solar Images

EURASIP Journal on Advances in Signal Processing, 2005
A new robust technique is presented for automated identification of sunspots on full-disk white-light (WL) solar images obtained from SOHO/MDI instrument and Ca II K1 line images from the Meudon Observatory.

Three hundred sixty‐degree prophylactic laser retinopexy versus focal laser during rhegmatogenous retinal detachment repair: A systematic review and meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract Purpose To compare the anatomic, functional and safety outcomes of intra‐operative 360‐degree prophylactic laser retinopexy versus focal laser retinopexy during pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD) and to assess the certainty of evidence.
