The Power of Sunspots: An Experimental Analysis [PDF]

We present an experiment in which extrinsic information (signals) may generate sunspot equilibria. The underlying coordination game has a unique symmetric non-sunspot equilibrium, which is also risk-dominant.

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.

Junctional sensitivity and atrophy progression rate of geographic atrophy secondary to age‐related macular degeneration

Acta Ophthalmologica, EarlyView.
Abstract Purpose To determine the relationship between the baseline junctional retinal sensitivity measured with microperimetry and the atrophy progression rate in eyes with geographic atrophy (GA) secondary to age‐related macular degeneration. Methods In this prospective cohort study, patients with GA were examined with fundus autofluorescence (FAF ...

The effect of rhegmatogenous retinal detachment on retinal oxygenation

Acta Ophthalmologica, EarlyView.
Abstract Purpose Little is known about the effects of retinal detachment on oxygen extraction from retinal vessels. The role of oxygen supply from the retinal vessels in a detached area has not previously been investigated in vivo in humans. Retinal oximetry is a non‐invasive measurement of retinal oxygen saturation.

Non-Fundamental Expectations and Economic Fluctuations: Evidence from Professional Forecasts [PDF]

It is theoretically possible that non-fundamental idiosyncratic shocks to agents’ rational expectations are a source of economic fluctuations. Studies using data on consumer and investor sentiment suggest that this is indeed a significant source of ...

Spectrophotometric study of sunspots

, 1953
After a brief review of some of the earlier work on sunspots the experimental technique employed for the spectrophotometry of sunspots and the results obtained in the case of 5 spots are described.

Sunspot simulations with MURaM

Astronomy & Astrophysics
Context. Existing sunspot simulations fail to reproduce the observed magnetic field distribution due to an artificially increased Bhor at the upper boundary. Aims.

Renal‐vascular axis: unmasking its role in vascular endothelial growth factor‐inhibitor vascular toxicity in cancer patients

British Journal of Pharmacology, EarlyView.
Abstract Vascular toxicity is a growing concern in cancer patients receiving vascular endothelial growth factor inhibitor (VEGFi) therapy, posing a significant threat to patient prognosis. While the primary mechanism of VEGFi‐induced vascular toxicity is linked to redox‐sensitive reactions that disrupt vascular tone, leading to hypertension and ...
