A five year record of high-frequency in situ measurements of non-methane hydrocarbons at Mace Head, Ireland [PDF]

Atmospheric Measurement Techniques, 2011
Continuous high-frequency in situ measurements of a range of non-methane hydrocarbons have been made at Mace Head since January 2005. Mace Head is a background Northern Hemispheric site situated on the eastern edge of the Atlantic. Five year measurements

Solar activity during the Holocene: the Hallstatt cycle and its consequence for grand minima and maxima [PDF]

, 2016
Cosmogenic isotopes provide the only quantitative proxy for analyzing the long-term solar variability over a centennial timescale. While essential progress has been achieved in both measurements and modeling of the cosmogenic proxy, uncertainties still ...

Maxima and Minima of Stationary Sequences

The Annals of Probability, 1979
We show that the asymptotic behavior of the normalized maxima of a stationary sequence satisfying a weak distributional mixing and bivariate condition is completely determined by the marginal distribution of the process. Sufficient conditions are given in order for the maxima and minima to be asymptotically independent.

Randomly Stopped Sums, Minima and Maxima for Heavy-Tailed and Light-Tailed Distributions

Axioms
This paper investigates the randomly stopped sums, minima and maxima of heavy- and light-tailed random variables. The conditions on the primary random variables, which are independent but generally not identically distributed, and counting random ...

Massive Fluctuations in the Derivatives of Pair Distribution Function Minima and Maxima During the Glass Transition

Metals
Parametric changes in the first coordination shell (FCS) of a vitreous metallic Pd42.5Cu30Ni7.5P20 alloy are analysed, aiming to confirm the identification of the glass transition temperature (Tg) via processing of XRD patterns utilising radial and pair ...

Some Results on Maxima and Minima of Real Functions of Vector Variables: A New Perspective

Axioms
This article presents a method for proving several theorems that enable the determination of the maxima and minima of certain classes of real-valued functions with vector variables, without relying on the classical theory based on partial derivatives ...

The global signal of the 11-year sunspot cycle in the stratosphere: Differences between solar maxima and minima

Meteorologische Zeitschrift, 2001
Based on the data of 4 solar cycles, the global structure of the signal of the 11-year sunspot cycle (SSC) in the stratosphere and troposphere was examined in earlier studies, using correlations between the solar cycle and heights and temperatures at ...
