Bimodal Distribution of Magnetic Fields and Areas of Sunspots [PDF]
, 2013 We applied automatic identification of sunspot umbrae and penumbrae to daily observations from the Helioseismic Magnetic Imager (HMI) on board the Solar Dynamics Observatory (SDO) to study their magnetic flux density (B) and area (A). The results confirm

Molecular Biomarkers in Meniere's Disease: A Scoping Review of Current Evidence
Otolaryngology–Head and Neck Surgery, EarlyView.Abstract Objective Meniere's disease is a complex chronic inner ear condition that is characterized by vertigo, tinnitus, aural fullness, and progressive hearing loss. Currently, diagnostic strategies remain symptom‐driven, and treatments focus on management of discrete episodes rather than targeting underlying pathophysiology.

Equipartition field strength on the sunspot boundary
Astronomy & AstrophysicsContext. A recent case study of a long-lived sunspot confirmed earlier observational indications that the outer boundary of sunspots is defined by an invariant value of the magnetic field strength.

Identification of beryllium hydride isotopomer lines in sunspot umbral spectra [PDF]
Serbian Astronomical Journal, 2008 A high resolution spectrum of FTS sunspot umbra of NSO/Kitt Peak was used to conduct a search for the molecular absorption lines due to BeH, BeD and BeT isotopomers. Analysis led to estimates of identification of the molecular lines of bands A - X (0,0),

Helioseismology of sunspots: how sensitive are travel times to the Wilson depression and to the subsurface magnetic field? [PDF]
, 2013 To assess the ability of helioseismology to probe the subsurface structure and magnetic field of sunspots, we need to determine how helioseismic travel times depend on perturbations to sunspot models. Here we numerically simulate the propagation of f, p1,

Pest Management Science, EarlyView.Adult Halyomorpha halys and Nezara viridula rapidly moved between berry crops and companion plants. Habitat use varied across environmental contexts, demonstrating that companion plantings function as dynamic elements in diversified cropping systems. Abstract BACKGROUND The brown marmorated stink bug Halyomorpha halys and the southern green stink bug ...

Deciphering Solar Magnetic Activity: Spotting Solar Cycle 25
Frontiers in Astronomy and Space Sciences, 2017 We present observational signatures of solar cycle 25 onset. Those signatures are visibly following a migratory path from high to low latitudes. They had starting points that are asymmetrically offset in each hemisphere at times that are 21–22 years ...

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 structures and photospheric ...
