Submergence of magnetic flux in interaction of sunspot groups [PDF]
, 2001 Submergence of magnetic flux is demonstrated in the process of evolution of sunspot groups NOAA 6850 (26 Sep.-07 Oct. 1991) and 7220/22 (06-17 July 1992). In both cases new magnetic flux emerges immediately behind an existing spotgroup. The new flux does

Observed Joy’s Law of Bipolar Magnetic Region Tilts at Emergence Supports the Thin Flux Tube Model
The Astrophysical Journal LettersBipolar sunspots, or more generally, bipolar magnetic regions (BMRs), are the dynamic magnetic regions that appear on the solar surface and are central to solar activity. One striking feature of these regions is that they are often tilted with respect to

The oscillatory response of the electroretinogram and neuronal adaptation
Acta Ophthalmologica, Volume 104, Issue 6, Page 616-637, September 2026.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.

The treatment of magnetic buoyancy in flux transport dynamo models [PDF]
, 2015 One important ingredient of flux transport dynamo models is the rise of the toroidal magnetic field through the convection zone due to magnetic buoyancy to produce bipolar sunspots and then the generation of the poloidal magnetic field from these bipolar

Animal Models and Experimental Medicine, Volume 9, Issue 7, Page 1420-1435, July 2026.Age‐related macular degeneration (AMD) involves lipid dysregulation and complement overactivation. Here, we characterize a double‐knockout ApoE−/−/Cfh−/− mouse as a model of early–intermediate retinal degeneration. These mice exhibit retinal pigment epithelium thinning, Bruch's membrane thickening, lipid accumulation, enhanced C5b‐9 deposition ...

The Astrophysical JournalThe historical reconstruction of the Sun’s surface magnetic field remains a persistent challenge, limiting our ability to investigate the long-term global properties of the Sun, including the evolution of the large-scale magnetic field, solar cycle ...

Food Science &Nutrition, Volume 14, Issue 6, June 2026.Cutaneous carotenoid measurements obtained non‐invasively by reflection spectroscopy (Veggie Meter and Biozoom) showed strong correlations with plasma carotenoid concentrations measured by HPLC in women across different BMI categories (Veggie Meter rs(151) = 0.697 and Biozoom rs(151) = 0.650, both p < 0.001).

Pragmatic randomised controlled trial of group psychoeducation versus group support in the maintenance of bipolar disorder. [PDF]
, 2011 Background: Non-didactically delivered curriculum based group psychoeducation has been shown to be more effective than both group support in a specialist mood disorder centre in Spain (with effects lasting up to five years), and treatment as usual in ...

Space Weather, Volume 24, Issue 6, June 2026.Abstract Ejections of magnetized plasma from the Sun, known as coronal mass ejections, can drive major geomagnetic activity if Earth‐directed, and are therefore monitored by space weather forecasters. The current focus being the forecast of the arrival time of a coronal mass ejection at Earth and the level of geomagnetic impact.
