Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

open access: yesBoreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Geomorphic signal of active faulting at the northern edge of Lut Block. Insights on the kinematic scenario of Central Iran [PDF]

open access: yes, 2016
Recent works documented Neogene to Quaternary dextral strike-slip tectonics along the Kuh-e-Sarhangi and Kuh-e-Faghan intraplate strike-slip faults at the northern edge of the Lut Block of Central Iran, previously thought to be dominated by sinistral ...

Single-grain TT-OSL bleaching characteristics: Insights from modern analogues and OSL dating comparisons [PDF]

open access: yesQuaternary Geochronology, 2019
Previous assessments of thermally transferred optically stimulated luminescence (TT-OSL) signal resetting in natural sedimentary settings have been based on relatively limited numbers of observations, and have been conducted primarily at the multi-grain scale of equivalent dose (De) analysis.

Palaeowinds and depositional conditions from Holocene loess in Sweden and Finland

open access: yesBoreas, EarlyView.
The nature of deglacial and Holocene wind regimes in Fennoscandia is debated, as is the degree to which wind‐blown loess deposits exist in the region. Loess deposits in Fennoscandia are often relatively thin, discontinuous and less well‐sorted than typical loess, and questions remain over the degree of their post‐depositional reworking and the impact ...

Optically stimulated luminescence of alexandrite

open access: yesOptical Materials: X
We report the optically stimulated luminescence (OSL) of natural alexandrite (BeAl2O4:Cr3+) from Brazil. Luminescence was stimulated using 470 nm blue, 525 nm green and 850 nm infrared light.

Chironomid‐based summer temperature reconstruction of the Eemian–Weichselian transition at Lichtenberg, northern Germany

open access: yesBoreas, EarlyView.
Understanding the temperature variability of past interglacial cycles is essential to predict future climates. We present a new summer temperature reconstruction, based on the subfossil chironomid record from a small palaeolake adjacent to the Middle Palaeolithic site of Lichtenberg, northern Germany. The record spans from the Saalian late glacial over

A Program Logic for Verifying Secure Routing Protocols [PDF]

open access: yes, 2014
The Internet, as it stands today, is highly vulnerable to attacks. However, little has been done to understand and verify the formal security guarantees of proposed secure inter-domain routing protocols, such as Secure BGP (S-BGP).

Maternal and child mental health and incident migraine in adolescence: An “All Our Families” prospective cohort study

open access: yesHeadache: The Journal of Head and Face Pain, EarlyView.
Abstract Objective To examine the association between mental health symptoms in youth and their mothers, and youth incident migraine, using prospectively collected, longitudinal data from the “All Our Families” (AOF) cohort study. Background Internalizing mental health symptoms, such as anxiety and depression, whether experienced by a child or his/her ...
