The January 2006 low ozone event over the UK [PDF]

Atmospheric Chemistry and Physics, 2007
In this paper we present a case study of a record low ozone event observed over the UK in January 2006. We focus on the dynamical processes that cause this event.

Bayesian and empirical-Bayesian evaluations of the Topp–Leone lifetime model using lower record statistics

AIP Advances
Record statistics are generally used to measure a process’ stochastic behavior at previously unheard-of values, either upper or lower. It can be obtained or calculated using order statistics from a sample whose size is dictated by the values and order of

Modeling with graded interfaces: Tool for understanding and designing record-high power and efficiency mid-infrared quantum cascade lasers

Nanophotonics
By employing a graded-interfaces model based on a generalized formalism for interface-roughness (IFR) scattering that was modified for mid-infrared emitting quantum cascade lasers (QCLs), we have accurately reproduced the electro-optical characteristics ...

Generalized Record Values from Distributions Having Power Hazard Function and Characterization

, 2019
This paper presents exact expressions as well as some recurrence relations for single and product moments for the generalized upper record values (k−th upper record values) , when the parent population follows the distribution having power hazard ...

Entropy Properties of k Record Values

, 2018
Record values can be viewed as order statistics from a sample whose size is determined by the values and the order of occurrence of observations. They are closely connected with the occurrence times of a corresponding non-homogeneous Poisson process and ...

Finiteness of Record values and Alternative Asymptotic Theory of Records with Atom Endpoints

, 2021
Asymptotic theories on record values and times, including central limit theorems, make sense only if the sequence of records values (and of record times) is infinite. If not, such theories could not even be an option. In this paper, we give necessary and/

A record of a stable transitional VGP in a Pliocene lava flow sequence from the Lesser Caucasus

Earth, Planets and Space
A paleomagnetic and paleointensity study has been performed on 28 basaltic flows from a sequence in the Lesser Caucasus. Two radiometric determinations yielded 3.45 ± 0.23 Ma in its lower and 3.43 ± 0.19 Ma in its upper part. Paleomagnetic determinations

The SPICE carbon isotope excursion in Siberia: a combined study of the upper Middle Cambrian-lowermost Ordovician Kulyumbe River section, northwestern Siberian Platform

, 2008
An integrated, high-resolution chemostratigraphic (C, O and Sr isotopes) and magnetostratigraphic study through the upper Middle Cambrian–lowermost Ordovician shallowmarine carbonates of the northwestern margin of the Siberian Platform is reported. The
