The heliospheric Hale cycle over the last 300 years and its implications for a “lost” late 18th century solar cycle
A Hale cycle, one complete magnetic cycle of the Sun, spans two complete Schwabe cycles (also referred to as sunspot and, more generally, solar cycles). The approximately 22-year Hale cycle is seen in magnetic polarities of both sunspots and polar fields, as well as in the intensity of galactic cosmic rays reaching Earth, with oddand even-numbered solar cycles displaying qualitatively different...
متن کاملEleven-year solar cycle signal throughout the lower atmosphere
[1] A statistically significant atmospheric signal, which represents the influence of solar radiation changes on our climate, is found in global data (1958–2003). Using a nonlinear, nonstationary time series analysis, called empirical mode decomposition, it is shown that atmospheric temperatures and geopotential heights are composed of five global oscillations and a trend. The fourth mode is sy...
متن کاملThe 22-year Solar Magnetic Cycle. Ii. Flare Activity
This paper is part of a larger set concerning the study of the last Hale cycle, a cycle that had an unexpected behaviour. Here we analyze the occurrence of the solar flares registered in X-ray as well as in Hα, with the aim to find an explanation for the activity much lower than predicted of the current 11-year solar cycle. We conclude that it could be determined by a pulse of flare activity in...

Introduction: Rheumatic heart disease still remains one of the leading causes of congestive heart failure and death owing to valvular pathologies, in developing countries. Valve replacement still remains the treatment of choice in such patients.The aim of this study wasto analyze the postoperative outcome of double valve replacement (Mitral and Aortic ) in patients of rheumatic heart disease. ...

Although this is a laudable long-term goal, it means that hospitals with a high proportion of Medicaid patients are much more likely to suffer a penalty for excessive readmissions than a hospital with a lower proportion of Medicaid patients. This is incredibly bad soc...
