Time series modelling of sunspot numbers using long range cyclical dependence [PDF]
This paper deals with the analysis of the monthly structure of sunspot numbers using a new technique based on cyclical long range dependence. The results show that sunspot numbers have a periodicity of 130 months, but more importantly, that the series is

The use of clozapine in the treatment of bipolar disorder in a patient with clinical comorbidities [PDF]
, 2007 Introduction: Patients with bipolar disorder report impairments of social functioning and the maintenance of relationships. This compromise is often accompanied by executive functioning deficits across mood states and periods of euthymia.

Flare-production potential associated with different sunspot groups
, 2017 In this study, we analysed different types (C, M, and X classes) of X-ray solar flares occurring in sunspot groups. The data cover 1996-2014 time interval, and a total of 4262 active regions (ARs) were included in the data set. We defined the solar-flare-

Stable sunspot equilibria in a cash-in-advance economy [PDF]
We analyze a monetary model with flexible labor supply, cash-inadvance constraints and seigniorage-financed government deficits. If the intertemporal elasticity of substitution of labor is greater than one, there are two steady states, one determinate ...

Solar flare forecasting using morphological properties of sunspot groups
, 2019 We describe a new tool developed for solar flare forecasting on the base of some sunspot group properties. Assuming that the flare frequency follows the Poisson statistics, this tool uses a database containing the morphological characteristics of the ...

An Alternative Approach to the Existence of Sunspot Equilibria [PDF]
This paper offers an alternative approach to the existence of sunspot equilibria. The economy has a single perishable good and fiat money within an overlapping generations framework with two possible extraneous events.
