Partition regularity of Pythagorean pairs

Forum of Mathematics, Pi
We address a core partition regularity problem in Ramsey theory by proving that every finite coloring of the positive integers contains monochromatic Pythagorean pairs (i.e., $x,y\in {\mathbb N}$ such that $x^2\pm y^2=z^2$ for some $z ...

Discrimination in autism as measured by minimal group and sheer difference experiments

British Journal of Psychology, EarlyView.
Abstract Autistic individuals often show fewer social biases than neurotypical people. Whether they show fewer discriminatory tendencies is however unclear. The present study examined discriminatory tendencies in autistic versus neurotypical individuals in the minimal group paradigm and the novel ‘sheer difference’ paradigm.

FORCING IN RAMSEY THEORY (Infinite Combinatorics and Forcing Theory) [PDF]

, 2017
Ramsey theory and forcing have a symbiotic relationship. At the RIMS Symposium on Infinite Combinatorics and Forcing Theory in 2016, the author gave three tutorials on Ramsey theory in forcing.

Beyond Sporting Talent: Other Determinants of Football Clubs’ Wage Bills

Bulletin of Economic Research, EarlyView.
ABSTRACT This article delves into the understanding of how football clubs determine wage bills to compensate talent. Using data from first‐division teams in elite European leagues, we estimate wage models based on indicators of sporting performance, “Elo ratings” as a proxy for clubs’ historical achievements and brand strength, and “media visibility ...

Jordan Curves: Ramsey Approach and Topology

Mathematics
We develop a topological-combinatorial framework applying classical Ramsey theory to systems of arcs connecting points on Jordan curves and their higher-dimensional analogues.

Holocene shoreline displacement and the impact of the Storegga tsunami on Hinnøya, northern Norway

Boreas, EarlyView.
The Holocene relative sea‐level (RSL) history of Norway's largest island, Hinnøya, has been investigated in detail, using sediment records from 25 isolation basins. The sediments were analysed for macrofossil and phytoplankton content, which served as the basis for identifying marine–lacustrine transitions, that is isolation contacts. Terrestrial plant

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

Boreas, 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 ...

Collectively enhanced Ramsey readout by cavity sub- to superradiant transition

Nature Communications
When an inverted ensemble of atoms is tightly packed on the scale of its emission wavelength or when the atoms are collectively strongly coupled to a single cavity mode, their dipoles will align and decay rapidly via a superradiant burst.

The commercialization of labour markets: Evidence from wage inequality in the Middle Ages

The Economic History Review, EarlyView.
Abstract This paper moves beyond the focus on ‘average’ wage trends in pre‐industrial economies by examining the broad diversity of pay rates and forms of remuneration across occupations and regions in medieval England. We find that whilst some workers enjoyed substantial growth in wage rates after the Black Death, there was a large group who ...

The Innocence of Imagination?

European Journal of Philosophy, EarlyView.
Abstract According to a widely held view both within and outside philosophy, imagination is innocent in the sense that it does not influence what we think and do. Hence, we can let our imagination wander anywhere. There are two ways of pushing back against this ‘innocence of imagination’ claim.
