effects of changes in moisture source and the upstream rainout on stable isotopes in precipitation a case study in nanjing eastern china
Hydrology and Earth System Sciences, 2015Co-Authors: Y. Tang, H. Pang, W. Zhang, S. HouAbstract:In the Asian monsoon region, variations in the stable isotopic composition of speleothems have often been attributed to the "amount effect". However, an increasing number of studies suggest that the "amount effect" in local precipitation is insignificant or even non-existent. To explore this issue further, we examined the variability of daily stable isotopic composition (δ 18 O) in precipitation from September 2011 to November 2014 in Nanjing, eastern China. We found that intra-seasonal variations of δ 18 O during summer were not significantly correlated with local rainfall amount but could be linked to changes in the moisture source Location and rainout processes in the source regions. Our findings suggest that the stable isotopes in summer precipitation could signal the Location Shift of precipitation source regions in the inter-tropical convergence zone (ITCZ) over the course of the monsoon season. As a result, changes in moisture source Location and upstream rainout effect should be taken into account when interpreting the stable isotopic composition of speleothems in the Asian monsoon region. In addition, the temperature effect on isotopic variations in non-monsoonal precipitation should also be considered because precipitation in the non-monsoon season accounts for about half of its annual precipitation.

Effects of aging on $$T_{1}$$ T 1
Brain Structure and Function, 2017Co-Authors: Max C Keuken, K Backhouse, S Beekhuizen, L Himmer, A Kandola, J J Lafeber, L Prochazkova, Anne C Trutti, P.-l. Bazin, Andreas SchaferAbstract:The aging brain undergoes several anatomical changes that can be measured with Magnetic Resonance Imaging (MRI). Early studies using lower field strengths have assessed changes in tissue properties mainly qualitatively, using $$T_{1}$$ T 1 - or $$T_{2}^{*}$$ T 2 ∗ - weighted images to provide image contrast. With the development of higher field strengths (7 T and above) and more advanced MRI contrasts, quantitative measures can be acquired even of small subcortical structures. This study investigates volumetric, spatial, and quantitative MRI parameter changes associated with healthy aging in a range of subcortical nuclei, including the basal ganglia, red nucleus, and the periaqueductal grey. The results show that aging has a heterogenous effects across regions. Across the subcortical areas an increase of $$T_{1}$$ T 1 values is observed, most likely indicating a loss of myelin. Only for a number of areas, a decrease of $$T_{2}^{*}$$ T 2 ∗ and increase of QSM is found, indicating an increase of iron. Aging also results in a Location Shift for a number of structures indicating the need for visualization of the anatomy of individual brains.
