Impact of lower stratospheric ozone on seasonal prediction systems

South African Journal of Science, 2014
We conducted a comparison of trends in lower stratospheric temperatures and summer zonal wind fields based on 27 years of reanalysis data and output from hindcast simulations using a coupled ocean- atmospheric general circulation model (OAGCM).

Poisson count time series

Journal of Time Series Analysis, EarlyView.
This article reviews and compares popular methods, some old and some recent, that produce time series having Poisson marginal distributions. The article begins by narrating ways where time series with Poisson marginal distributions can be produced.

The Cytoprotective Role of Antioxidants in Mammalian Cells Under Rapidly Varying UV Conditions During Stratospheric Balloon Campaign

Frontiers in Pharmacology, 2019
The current age of dynamic development of the space industry brings the mankind closer to routine manned space flights and space tourism. This progress leads to a demand for intensive astrobiological research aimed at improving strategies of the ...

Government Spending and Civic Engagement: Exploring the Role of Civil Society Participation and Voting in 28 Democracies

Kyklos, EarlyView.
ABSTRACT This study offers causal evidence on how distinct forms of civic engagement affect government spending across 28 democracies between 2000 and 2024. Its main innovation lies in disentangling the fiscal effects of two channels of engagement—civil society participation and electoral turnout—through an original identification strategy that ...

No legacy effects of severe drought on carbon and water fluxes in a Mediterranean oak forest

Plant Biology, EarlyView.
A Mediterranean Quercus ilex forest was severely affected by a drought in 2017 but fully recovered in the following year, supported by favourable weather and growing conditions both before and after the event. Abstract Severe droughts affect vegetation through several processes, such as hydraulic failure, early leaf senescence, depletion of carbon ...

On goodness‐of‐fit testing for self‐exciting point processes

Scandinavian Journal of Statistics, EarlyView.
Abstract Despite the wide usage of parametric point processes in theory and applications, a sound goodness‐of‐fit procedure to test whether a given parametric model is appropriate for data coming from a self‐exciting point process has been missing in the literature.
