In a recent paper, SFI Complexity Postdoctoral Fellow Yuanzhao Zhang and co-author William Gilpin show that a deceptively ...

This paper is a review of a few problems associated with the observation of scaling laws in urban systems. Two levels in the spatial organization have to be formalized, cities as systems and systems ...

SFI External Professor Constantino Tsallis (Centro Brasileiro de Pesquisas Físicas) will serve as co-chair and synthesis lead ...

Models of how things spread often assume that transmission mechanisms are fixed over time. However, social contagions-the spread of ideas, beliefs, innovations-can lose or gain in momentum as they ...

Assembly theory has received considerable attention in the recent past. Here we analyze the formal framework of this model and show that assembly pathways coincide with certain minimal hyperpaths in B ...

Darroch, Simon A. F.; Michelle M. Casey; Alison T. Cribb; Amanda E. Bates; Matthew E. Clapham… Marcus J. Hamilton et al. Understanding the role of humans as 'ecosystem engineers' requires a deep-time ...

We construct the most general form of our previously proposed nonlinear extension of quantum mechanics that possesses three basic properties. Unlike the simpler model, the new version is not ...

It has been found recently that more data can, counter-intuitively, hurt the performance of deep neural networks. Here, we show that a more extreme version of the phenomenon occurs in data-driven ...

PicAxe is open-source Python software that researchers can use to extract figures from corpora of PDF files that contain text and images. It is designed to extract figures from corpora that include ...

Despite the appeal of screening travellers to prevent case importation during infectious disease outbreaks, evidence shows that symptom screening is largely ineffective in delaying the geographical ...

Dunbar's framework highlights the challenge of maintaining large, stable social networks given cognitive constraints. Expanding on this, I propose that fractal social networks function as lossy ...

Background Insight into the rigidity or flexibility of molecular structures is integral for a series of common research questions in molecular biology, including the identification of functional ...
