Preliminary results towards the equivalence of transformed continuous-wave Optically Stimulated Luminescence (CW-OSL) and linearly-modulated (LM-OSL) signals in quartz
(Versita, 2011-09)The present paper presents a comparative experimental study of two commonly measured Optically Stimulated Luminescence (OSL) signals in quartz. The experimental study measures both the continuous wave OSL (CW-OSL) and the ... -
Preliminary TL and OSL investigations of obsidian samples
(Univ Agean, Dept Mediterranean Stud, 2010)Obsidian is a volcaniclastic mineral extremely hard to break, which was used in prehistoric Greece (and elsewhere in the World), in order to provide tools, weapons, knives and arrowheads. The present work aims to characterize ... -
Projected changes in extreme temperature and precipitation indices over CORDEX-MENA domain
(MDPI AG, 2021-05)In this study, projected changes in climate extreme indices defined by the Expert Team on Climate Change Detection and Indices were investigated over Middle East and North Africa. Changes in the daily maximum and minimum ... -
Projected changes in temperature and precipitation climatology of Central Asia CORDEX Region 8 by using RegCM4.3.5
(Elsevier Ltd, 2017-01-01)This work investigated projected future changes in seasonal mean air temperature (°C) and precipitation (mm/day) climatology for the three periods of 2011–2040, 2041–2070, and 2071–2100, with respect to the control period ... -
Projections of climate change in the Mediterranean Basin by using downscaled global climate model outputs
(Wiley-Blackwell, 2015-11-30)The Mediterranean Basin is one of the regions that shall be affected most by the impacts of the future climate changes on hydrology and water resources. In this study, projected future changes in mean air temperature and ... -
Quantum fisher information of several qubitsin the superposition of A GHZ and two W stateswith arbitrary relative phase
(Springer/Plenum Publishers, 2014-09)We study the quantum Fisher information (QFI) of a system of several particles which is in a superposition of a GHZ and two W states with arbitrary relative phase. We show that as the number of particles increases from 3 ... -
Quaternary rock uplift rates and their implications for the western flank of the North Anatolian Fault restraining bend; inferences from fluvial terrace ages
