The Early Upper Palaeolithic open‐air site of Friedrichsdorf‐Seulberg, Germany, in the context of the northern central European Aurignacian

open access: yesBoreas, EarlyView.
Our knowledge of the Early Upper Palaeolithic occupation in northern central Europe is very limited, and recent research at the open‐air site of Friedrichsdorf‐Seulberg in Hesse, Germany, provides important new information on the Aurignacian. The site is rather small (26.5 m2) and spatial analysis identified a central hearth with two associated ...

Haemostatic changes and bleeding with anti‐IL‐6 directed therapy in autoimmune diseases

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Anti‐IL‐6 directed therapy, especially tocilizumab (TCZ), is widely used for the treatment of autoimmune diseases such as rheumatoid arthritis, giant cell arteritis and systemic juvenile idiopathic arthritis. Next to being a master regulator of inflammation, IL‐6 also is an important regulator of haemostasis. Although generally well tolerated,

Determining impact angle from the spatial distribution of shock metamorphism: A case study of the Gosses Bluff (Tnorala) impact structure, Australia

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The majority of planetary impacts occur at oblique angles. Impact structures on Earth are commonly eroded or buried, rendering the identification of the direction and angle of impact—using methods such as asymmetries in ejecta distribution, surface topographic expression, central uplift structure, and geophysical anomalies—challenging. In this

The lithic assemblage of the promontory site at Ras il-Pellegrin

open access: yesTraces in Time, 2011
The promontory of Ras il-Pellegrin, located in the northwestern part of Malta, is nowadays an isolated,yet archaeologically rich site. The few archaeological studies on this promontory and in the surrounding area indicate an interesting prehistoric use ...

Výzkum pravěkého osídlení v západní části pohoří Sabaloka v centrálním Súdánu: poznatky z výzkumné sezóny 2018 | Exploration of the late prehistoric occupation in the western part of Jebel Sabaloka in central Sudan: findings of the 2018 field campaign [PDF]

open access: yesPražské Egyptologické Studie, 2019
The most significant findings of the ongoing exploration of the Fox Hill site in the western part of the Sabaloka Mountains include the detection of extensive remains of a more-than-one-metre thick deposit on Terrace 1, tentatively interpreted as a relic

Vertical profiling of shock attenuation at the Rochechouart impact structure, France

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Rochechouart, south‐west France, is a complex impact structure. Here, we present the first report of shock barometry of quartz from what are likely parautochthonous basement units at depth, based on samples from the 2017 C.I.R.I.R drilling campaign. The crystallographic orientations of 725 sets of PDFs in 512 quartz grains in samples from four

Static recrystallization of shocked calcite in Ries impact breccias

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Calcite is prone to chemical and microstructural modifications, especially after having been strained at high stresses and strain rates, as during hypervelocity impact events. These modifications include precipitation from pore fluid as well as replacement of strained volumes by recrystallization. In calcite aggregates of a metagranite breccia

Confirmation of the impact origin of the Late Ordovician Tvären impact structure (southeast Sweden) and emplacement of impactites in a marine setting

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The Tvären structure in southeastern Sweden has been listed as a confirmed marine‐target impact structure for decades. However, to date, no measurements and/or indexed data of planar deformation features in quartz grains from the structure have been published or any other unequivocal evidence of impact.

Polymict melt‐bearing breccia dikes in the Morokweng impact structure formed by slip‐induced mechanical mixing of pseudotachylite and cataclasite along large‐displacement impact faults

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract A core drilled through shocked and faulted Archean granitoid gneisses and dolerites in the eroded peak ring of the 70–80 km diameter Morokweng impact structure intersects multiple centimeter‐ to meter‐wide clastic‐matrix breccias containing a polymict clast population of lithic and mineral clasts and altered, millimeter‐ to centimeter ‐size ...
