The weak Ramsey property and extreme amenability
Forum of Mathematics, SigmaWe extend the Kechris–Pestov–Todorčević correspondence to weak Fraïssé categories and automorphism groups of generic objects. The new ingredient is the weak Ramsey property.

Modeling of Complex Systems by Means of Partial Algebras
Mendel, 2019 Complex systems are very hard to describe by some unified language and calculus. In cases when their nature is very heterogeneous is possible to use with advantage state description.

New Results From the Pre‐Pottery Neolithic Site of Al Uyaynah, Tabuk, in Northwestern Saudi Arabia
Arabian Archaeology and Epigraphy, EarlyView.ABSTRACT Al Uyaynah is a low sandstone mound on an alluvial plain, long known for its extensive surface remains of stone‐built circular and rectangular structures. Following test excavations in 2012, more detailed excavation was undertaken in 2016 within one of the largest rectangular stone structures.

Geophysical Monograph Series, Page 169-190., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Temporal Ramsey Graphs: The Ramsey Kinematic Approach to the Motion of Systems of Material Points
DynamicsThe Ramsey approach is applied to analyses of the kinematics of systems built of non-relativistic, motile point masses/particles. This approach is based on colored graph theory. Point masses/particles serve as the vertices of the graph.

Theories of Interest and Their Relation to the Gesell–Keynes Theory
The American Journal of Economics and Sociology, EarlyView.ABSTRACT We consider theories of interest as they relate to what we will call the Gesell‐Keynes (GK) theory which is essentially a real theory of capital accumulation with a monetary constraint that arises because of a liquidity return on holding money.

Riemannian Manifolds, Closed Geodesic Lines, Topology and Ramsey Theory
MathematicsWe applied the Ramsey analysis to the sets of points belonging to Riemannian manifolds. The points are connected with two kinds of lines: geodesic and non-geodesic.

Archaeometry, EarlyView.Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Application of Multi‐Method Dating for Understanding the Gravettian North of Moravia, Central Europe
Archaeometry, EarlyView.ABSTRACT This article presents the results of integrating three methods to assess the age of the Upper Palaeolithic site of Pietraszyn 11 (SW Poland), close to the Moravian Gate. Sediment chronology determined using optically stimulated luminescence produced promising, yet ambiguous results (51.0 ± 3.7 to 20.3 ± 0.7 ka).

Archaeometry, EarlyView.ABSTRACT Vlaardingen (VL) communities on the Dutch West coast (3400–2200 bce) are part of a unique, long‐term continuity in the European Neolithic. Despite large‐scale changes in European populations during the Neolithic, the genomic diversity and cultural practices of VL communities can be retraced to the Mesolithic.
