On the negative coupling O(N) model in 2d at high temperature
In this work, I consider N-component scalar quantum field theory in two dimensions interacting with an upside-down quartic potential. Working in the large N limit, the model can be solved non-perturbatively using the saddle-point method for sufficiently ...

Based on the layered structural characteristics of the strata, this study summarizes four typical overburden structural types under the geological conditions of the 51408 working face. Through theoretical derivation and numerical simulation, the study reveals the stepwise failure characteristics of the overburden and analyzes the variations in ...

Abstract The boundary between the Northern Andean block and the South American plate is a first‐order tectonic structure in Colombia with historically M > 7 earthquakes. However, details about individual sections of the system remain unknown. We illuminate the seismotectonic of the Algeciras fault by investigating an earthquake sequence that started on

A path to reconciliation between Indigenous and settler–colonial epistemologies
There is a movement across settler–colonial institutions of education and research to engage with Indigenous Peoples and Knowledges. Many settler and Indigenous governments are pursuing pathways to move forward together to address global problems such as climate change. However, given the pervasive history of exploitation and displacement of Indigenous

Predefined‐time distributed event‐triggered algorithms for resource allocation
This paper considers the distributed resource allocation problem over an undirected multi‐agent system by proposing a predefined‐time distributed algorithm. Furthermore, to reduce the communication burden, the static and dynamic event‐triggered mechanisms are provided.
