Adaptive Decision‐Making “Fast” and “Slow”: A Model of Creative Thinking
European Journal of Neuroscience, Volume 61, Issue 5, March 2025.The adaptive decision‐making model incorporates a search type involving dual clustering and switching systems. It also integrates fast and slow strategies and temporal modulation, which varies based on individual differences. The brain model depicts a dual system of bottom‐up and top‐down processes, illustrated by the two arrows.

The Ramsey Theory of Henson graphs
, 2020 Analogues of Ramsey's Theorem for infinite structures such as the rationals or the Rado graph have been known for some time. In this context, one looks for optimal bounds, called degrees, for the number of colors in an isomorphic substructure rather than

Hypergraph Anti‐Ramsey Theorems
Journal of Graph TheoryABSTRACTThe anti‐Ramsey number of an ‐graph is the minimum number of colors needed to color the complete ‐vertex ‐graph to ensure the existence of a rainbow copy of . We establish a removal‐type result for the anti‐Ramsey problem of when is the expansion of a hypergraph with a smaller uniformity. We present two applications of this result.

Size‐Ramsey numbers of graphs with maximum degree three
Journal of the London Mathematical Society, Volume 111, Issue 3, March 2025.Abstract The size‐Ramsey number r̂(H)$\hat{r}(H)$ of a graph H$H$ is the smallest number of edges a (host) graph G$G$ can have, such that for any red/blue colouring of G$G$, there is a monochromatic copy of H$H$ in G$G$. Recently, Conlon, Nenadov and Trujić showed that if H$H$ is a graph on n$n$ vertices and maximum degree three, then r̂(H)=O(n8/5 ...

Canonizing structural Ramsey theorems [PDF]
Discrete Mathematics, 2019 At the beginning of 1950's Erd\H os and Rado suggested the investigation of the Ramsey-type results where the number of colors is not finite. This marked the birth of the so-called canonizing Ramsey theory. In 1985 Pr mel and Voigt made the first step towards the structural canonizing Ramsey theory when they proved the canonical Ramsey property for ...

Forecasting Recurrent Large Earthquakes From Paleoearthquake and Fault Displacement Data
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 2, February 2025.Abstract Long recurrence intervals of large earthquakes relative to the historical record mean that geological data are often utilized to inform forecasts of future events. Geological data from any particular fault may constrain the timing of past earthquakes (paleoearthquake data), or simply the time period over which a certain amount of fault ...

Natural Resources Forum, Volume 49, Issue 1, Page 800-823, February 2025.Abstract India, not being an exception from the rest of the globe, has also been suffering from the unprecedented challenges of survival of the ecosphere, which is highly threatened by a continuous weakening of the environmental quality as a result of accelerated accumulation of anthropogenic emissions in the biosphere. As an immediate aftermath of the

Optimal allocation of resources between control and surveillance for complex eradication scenarios
Methods in Ecology and Evolution, Volume 16, Issue 2, Page 388-399, February 2025.Abstract To ensure the success of complex invasive‐species eradication programs across large areas, efficient and effective resource allocation is crucial. This study incorporates analytical Bayesian solutions and measures of uncertainty into a framework of progressive management to guide optimal resource allocation between control (mop‐ups) and ...

Approximate Euclidean Ramsey theorems
Journal of Computational Geometry, 2010 According to a classical result of Szemerédi, every dense subset of 1,2,…,N contains an arbitrary long arithmetic progression, if N is large enough. Its analogue in higher dimensions due to Fürstenberg and Katznelson says that every dense subset of {1,2,…,N}d contains an arbitrary large grid, if N is large enough.
