Soil weathering dynamics and erosion in a dry oceanic area of the southern hemisphere (Otago, New Zealand).

Landscape evolution is driven by tectonics, climate and surface denudation. In New Zealand, tectonics and steep climatic gradients cause a dynamic landscape with intense chemical weathering, rapid soil formation, and high soil losses. In this study, soil, and elemental redistribution along two adjacent hillslopes in East Otago, New Zealand, having different landscape settings (ridge versus valley) are compared to identify soil weathering and erosion dynamics.

Seismic history of western Anatolia during the last 16 kyr determined by cosmogenic Cl dating.

Unlabelled: Western Anatolia is one of the most seismically active regions worldwide. To date, the paleoseismic history of many major faults, in terms of recurrence intervals of destructive earthquakes, their magnitude, displacement, and slip rates is poorly understood. Regional crustal extension has produced major horst-graben systems bounded by kilometer-scale normal faults locally in carbonates, along which vertical crustal displacements occurred.

The Nature and Clinical Significance of Atypical Mononuclear Cells in Infectious Mononucleosis Caused by the Epstein-Barr Virus in Children.

Atypical mononuclear cells (AM) appear in significant numbers in peripheral blood of patients with Epstein-Barr virus (EBV)-associated infectious mononucleosis (IM). We investigated the number and lineage-specific clusters of differentiation (CD) expression of atypical mononuclear cells in 110 children with IM using the anti-CD antibody microarray for panning leukocytes by their surface markers prior to morphology examination. The AM population consisted primarily of CD8+ T cells with a small fraction (0%-2% of all lymphocytes) of CD19+ B lymphocytes.

Fault Scarp Dating Tool - a MATLAB code for fault scarp dating using in-situ chlorine-36 supplemented with datasets of Yavansu and Kalafat faults.

We publish a MATLAB code used to analyze concentration profile of cosmogenic Cl accumulated in-situ through a rupture history of the fault scarps in western Turkey (Mozafari et al., 2019). The code is a version of the forward modeling Matlab code -Fault Scarp Dating Tool- (Tikhomirov, 2014).

Fast long-term denudation rate of steep alpine headwalls inferred from cosmogenic Cl depth profiles.

Quantifications of in-situ denudation rates on vertical headwalls, averaged over millennia, have been thwarted because of inaccessibility. Here, we benefit from a tunnel crossing a large and vertical headwall in the European Alps (Eiger), where we measured concentrations of in-situ cosmogenic Cl along five depth profiles linking the tunnel with the headwall surface. Isotopic concentrations of Cl are low in surface samples, but high at depth relative to expectance for their position.

Widespread erosion on high plateaus during recent glaciations in Scandinavia.

Glaciers create some of Earth's steepest topography; yet, many areas that were repeatedly overridden by ice sheets in the last few million years include extensive plateaus. The distinct geomorphic contrast between plateaus and the glacial troughs that dissect them has sustained two long-held hypotheses: first, that ice sheets perform insignificant erosion beyond glacial troughs, and, second, that the plateaus represent ancient pre-glacial landforms bearing information of tectonic and geomorphic history prior to Pliocene-Pleistocene global cooling (~3.5 Myr ago).
