The ‘Great Frost’ of 1708–9 in Britain and the Condescensions of Posterity
History, EarlyView.Abstract This article explores the ‘great frost’ of 1709 and its impact on economic life in Britain, challenging a popular view that, based on gross domestic product (GDP) estimates, it was catastrophic. It shows that the annual GDP figures for the period have such wide error margins that they cannot establish the scale of the disruption; that the ...

Maximum Sunspot Numbers and Active Days [PDF]
Journal of Astronomy and Space Sciences, 2013 Parameters associated with solar minimum have been studied to relate them to solar activity at solar maximum so that one could possibly predict behaviors of an upcoming solar cycle.

Book Value Risk Management of Banks: Limited Hedging, HTM Accounting, and Rising Interest Rates
Journal of Accounting Research, EarlyView.ABSTRACT We document that as interest rates rose in 2022, banks largely left long‐duration assets exposed to interest rate risk while shielding the accounting value of their balance sheets. Call report and Securities and Exchange Commission (SEC) data show that only about 6% of U.S.

A 22-year cycle in the F layer ionization of the ionosphere [PDF]
Annales Geophysicae, 1997 The double-sunspot-cycle variation in terrestrial magnetic activity has been well known for about 30 years. In 1990 we examined and compared the low-solar-activity (LSA) part of two consecutive cycles and predicted from this database and from ...

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.

Directional time-distance probing of model sunspot atmospheres [PDF]
, 2015 A crucial feature not widely accounted for in local helioseismology is that surface magnetic regions actually open a window from the interior into the solar atmosphere, and that the seismic waves leak through this window, reflect high in the atmosphere ...

Revisiting the Question: The Cause of the Solar Cycle Variation of Total Solar Irradiance
Advances in Astronomy, 2019 The Mg II index and sunspot area are usually used to represent the intensification contribution by solar bright structures to total solar irradiance (TSI) and sunspot darkening, respectively.

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.

Retinal dystrophies simulating geographic atrophy: A diagnostic challenge
Acta Ophthalmologica, EarlyView.Abstract Geographic atrophy (GA) is the chronic loss of retinal pigment epithelium, photoreceptors and choriocapillaris, marking the dry late stage of age‐related macular degeneration (AMD). GA prevalence is expected to rise in the upcoming decades. Advanced GA leads to central scotomas, reducing visual acuity and quality of life, potentially resulting

Applied Artificial Intelligence, 2022 Solar activity has significant impacts on human activities and health. One most commonly used measure of solar activity is the sunspot number. This paper compares three important non-deep learning models, four popular deep learning models, and their five
