Detectability limits of scaling laws
Alec Kirkley
Power law scaling relations between size and output are central to quantitative theories of cities, organisms, and other complex systems. Competing theories predict scaling exponen…
Characterizing network circuity among heterogeneous urban amenities
Bibandhan Poudyal, Gourab Ghoshal, Alec Kirkley
The spatial configuration of urban amenities and the streets connecting them collectively provide the structural backbone of a city, influencing its accessibility, vitality, and ul…
Heterogeneous message passing for heterogeneous networks
George T. Cantwell, Alec Kirkley, Filippo Radicchi
Message passing (MP) is a computational technique used to find approximate solutions to a variety of problems defined on networks. MP approximations are generally accurate in local…
Compressing network populations with modal networks reveals structural diversity
Alec Kirkley, Alexis Rojas, Martin Rosvall +1
Analyzing relational data consisting of multiple samples or layers involves critical challenges: How many networks are required to capture the variety of structures in the data? An…
The impact of inter-city mobility on urban welfare
Sayat Mimar, David Soriano-Paños, Alec Kirkley +5
While much effort has been devoted to understand the role of intra-urban characteristics on sustainability and growth, much remains to be understood about the effect of inter-urban…
Spatial regionalization based on optimal information compression
Alec Kirkley
Regionalization, spatially contiguous clustering, provides a means to reduce the effect of noise in sampled data and identify homogeneous areas for policy development among many ot…
Online geolocalized emotion across US cities during the COVID crisis: Universality, policy response, and connection with local mobility
Shihui Feng, Alec Kirkley
As the COVID-19 pandemic began to sweep across the US it elicited a wide spectrum of responses, both online and offline, across the population. To aid the development of effective…
Information theoretic network approach to socioeconomic correlations
Alec Kirkley
Due to its wide reaching implications for everything from identifying hotspots of income inequality to political redistricting, there is a rich body of literature across the scienc…
Impact of urban structure on infectious disease spreading
Javier Aguilar, Aleix Bassolas, Gourab Ghoshal +8
The ongoing SARS-CoV-2 pandemic has been holding the world hostage for more than a year now. Mobility is key to viral spreading and its restriction is the main non-pharmaceutical i…
Robust Design from Systems Physics
Andrei A. Klishin, Alec Kirkley, David J. Singer +1
A crucial challenge in engineering modern, integrated systems is to produce robust designs. Ensuring robust design is difficult because subsystem couplings produce unpredictable re…
From the betweenness centrality in street networks to structural invariants in random planar graphs
Alec Kirkley, Hugo Barbosa, Marc Barthelemy +1
We demonstrate that the distribution of betweenness centrality (BC), a global structural metric based on network flow, is an invariant quantity in most planar graphs. We confirm th…
