Precise Deviations Results for the Maxima of Some Determinantal Point Processes: the Upper Tail [PDF]

open access: yes, 2016
We prove precise deviations results in the sense of Cram\'er and Petrov for the upper tail of the distribution of the maximal value for a special class of determinantal point processes that play an important role in random matrix theory.

Aerosol radiative impact during the summer 2019 heatwave produced partly by an inter-continental Saharan dust outbreak – Part 1: Short-wave dust direct radiative effect [PDF]

open access: yesAtmospheric Chemistry and Physics, 2021
The short-wave (SW) direct radiative effect (DRE) during the summer 2019 heatwave produced partly by a moderate, long-lasting Saharan dust outbreak over Europe is analysed in this study.

Metastability in zero-temperature dynamics: Statistics of attractors [PDF]

open access: yes, 2004
The zero-temperature dynamics of simple models such as Ising ferromagnets provides, as an alternative to the mean-field situation, interesting examples of dynamical systems with many attractors (absorbing configurations, blocked configurations, zero ...

Akumulacija olova u drvenastim biljkama NP “Fruška gora”

open access: yesGlasnik Šumarskog Fakulteta Univerziteta u Banjoj Luci, 2007
Olovo je teški metal koji pokazuje izuzetno štetan efekat, kako na biljke tako i na životinje i čoveka, jer ispoljava kumulativan, sporodelujući efekat. Koncentracija olova je ispitivana u biljnom materijalu sakupljenom na sedam odabranih lokaliteta duž

Strip road spacing and the physical strain put on forest workers during pulpwood cutting

open access: yesSilva Fennica, 1977
The physical strain put on forest workers and work time consumption during pulpwood cutting were compared when the bolts were stacked at the side of strip road, the strip road spacings being 15-25 m and 26-35 m, and when stacked at scattered points along

Gravitomagnetic effects in Kerr-de Sitter space-time [PDF]

open access: yes, 2009
We explicitly worked out the orbital effects induced on the trajectory of a test particle by the the weak-field approximation of the Kerr-de Sitter metric.
