Implementing the Soil Enrichment Protocol at Scale: Opportunities for an Agricultural Carbon Market
High-quality agricultural carbon credits that incentivize regenerative practices can help address climate change through greenhouse gas …
Contagious disruptions and complexity traps in economic development
Poor economies not only produce less; they typically produce things that involve fewer inputs and fewer intermediate steps. Yet the …
Coupled catastrophes: sudden shifts cascade and hop among interdependent systems
An important challenge in several disciplines is to understand how sudden changes can propagate among coupled systems. Examples include …
Cascades in multiplex financial networks with debts of different seniority
The seniority of debt, which determines the order in which a bankrupt institution repays its debts, is an important and sometimes …
Jigsaw percolation: What social networks can collaboratively solve a puzzle?
We introduce a new kind of percolation on finite graphs called jigsaw percolation. This model attempts to capture networks of people …
Threshold cascades with response heterogeneity in multiplex networks
Elements of networks interact in many ways, so modeling them with graphs requires multiple types of edges (or network layers). Here we …
Inside Money, Procyclical Leverage, and Banking Catastrophes
We explore a model of the interaction between banks and outside investors in which the ability of banks to issue inside money …
Bottom-up model of self-organized criticality on networks
The Bak-Tang-Wiesenfeld (BTW) sandpile process is an archetypal, stylized model of complex systems with a critical point as an …
Controlling self-organizing dynamics using models that self-organize
Controlling self-organizing systems is challenging because the system responds to the controller. Here, we develop a model that …
Transdisciplinary electric power grid science
When a tenth of humanity lost power over 2 days in India in July 2012, technical failure was not the only culprit. Like many recent …
Boundary Growth in One-Dimensional Cellular Automata
The boundaries of one-dimensional, two-color cellular automata depending on four cells and begun from simple initial conditions are …
Multiplexity-facilitated cascades in networks
Elements of networks interact in many ways, so modeling them with graphs requires multiple types of edges (or network layers). Here we …
Suppressing cascades of load in interdependent networks
Understanding how interdependence among systems affects cascading behaviors is increasingly important across many fields of science and …
A search for the simplest chaotic partial differential equation
A numerical search for the simplest chaotic partial differential equation (PDE) suggests that the Kuramoto–Sivashinsky equation is the …
Packard snowflakes on the von Neumann neighborhood
In 1984, Packard [1] introduced simple planar cellular automata to emulate the growth of snow crystals. These Packard Snowflakes have …
