Sunspot Number Variations [PDF]
In this activity students find the patterns that emerge when sunspot numbers are plotted over a period of time. Students learn about sunspot variations and the solar cycle, and are able to predict future solar minimums and solar maximums.

Rational Expectations Fools' Bubbles
International Economic Review, EarlyView.ABSTRACT We develop a rational, Walrasian model of speculative bubbles inspired by the Kindleberger–Minsky view, which describes bubbles as wave‐like market processes. Touched off by an initial shock, price booms are initially self‐reinforcing but become self‐destructive later when prices surpass fundamental value.

Banking with Inside Money: An Efficiency Analysis
Journal of Money, Credit and Banking, EarlyView.Abstract We show that banks do not decentralize the first best in a nominal Diamond–Dybvig economy with inside money. Furthermore, state‐contingent deposit contracts do not expand the consumption possibility set to include the first best either. Central banks can improve welfare but only for savers and only with unconventional monetary policy. Finally,

Long-Term Variation of the Number of Sunspots per Group [PDF]
Long-term reconstructions of sunspot number (SSN) and group number (GN) often tacitly assume that the basic characteristics of solar activity remain unchanged even over long times, e.g., that the number of sunspots and the number of sunspot groups now ...

Journal of Anatomy, Volume 246, Issue 4, Page 558-574, April 2025.Here, we present the most complete dataset to date on the endosseous labyrinths of extant crocodylians. Using 3D geometric morphometrics, we show that allometry constitutes a major contributor of the shape variation of the crocodylian endosseous labyrinths and that the development of this structure is likely linked to the braincase conformation, in all

Studies on Correlation between Sporadic E & Sunspot Number [PDF]
, 1972 145-147The dependence of sporadic E occurrence on the sunspot number is studied by evaluating the correlation coefficient, and by finding out the significance of the correlation at different stations for different limiting values of fEs .

Journal of Paediatrics and Child Health, EarlyView.ABSTRACT Background Retinopathy of prematurity (ROP) is a neurovascular disorder that may affect not only the retina but also the brain structures involved in visual processing. The relationship between ROP severity and the volumetric development of these regions remains unclear.

Detecting Periodicity of a General Stationary Time Series via AR(2)‐Model Fitting
Journal of Time Series Analysis, EarlyView.ABSTRACT Estimating the periodicity of a stationary time series via fitting a second‐order stationary autoregressive (AR(2)) model has been initiated by the seminal paper of Yule (1927). We investigate properties of this procedure when applied to general stationary processes possessing a spectral density with a dominant peak at some unknown frequency ...

Von Lindener's sunspot data: sunspot group number and individual sunspot number
Hayakawa et al. (2023) derived sunspot group number and individual sunspot number from von Liindener's records. These data have been extracted from von Lindener's manuscript (Akc.1985/15) in the Library of Wrocław University and Bode (1819).

Duplicitous Remembrance: Confessing Self‐Deception with Augustine
Modern Theology, EarlyView.Abstract While self‐deception has long been a topic of interest in psychology and analytic philosophy—and increasingly in the academic study of theology and religion—direct engagement with Augustine on self‐deception remains underexplored in contemporary scholarship.
