Optimal Dynamic Distributed MIS
Keren Censor-Hillel, Elad Haramaty, Zohar Karnin
Finding a maximal independent set (MIS) in a graph is a cornerstone task in distributed computing. The local nature of an MIS allows for fast solutions in a static distributed sett…
Low-moment ferrimagnetic phase of the Heusler compound Cr2CoAl
Michelle E. Jamer, Luke G. Marshall, George E. Sterbinsky +2
Synthesizing half-metallic fully-compensated ferrimagnets that form in the inverse Heusler phase could lead to superior spintronic devices. These materials would have high spin pol…
Regularity underlies erratic population abundances in marine ecosystems
Jie Sun, Sean P. Cornelius, John Janssen +2
The abundance of a species' population in an ecosystem is rarely stationary, often exhibiting large fluctuations over time. Using historical data on marine species, we show that th…
Scattering-like phenomena of the periodic defocusing NLS equation
T. Kappeler, B. Schaad, P. Topalov
In this paper we prove approximation properties of the solutions of the defoucsing NLS equation on the circle by nearly linear flows. In addition we show that spatially periodic so…
Tracking Employment Shocks Using Mobile Phone Data
Jameson L. Toole, Yu-Ru Lin, Erich Muehlegger +3
Can data from mobile phones be used to observe economic shocks and their consequences at multiple scales? Here we present novel methods to detect mass layoffs, identify individuals…
Emergence of bimodality in controlling complex networks
Tao Jia, Yang-Yu Liu, Endre Csóka +3
Our ability to control complex systems is a fundamental challenge of contemporary science. Recently introduced tools to identify the driver nodes, nodes through which we can achiev…
