Hopfield Networks as Models of Emergent Function in Biology
Maria Yampolskaya, Pankaj Mehta
Hopfield models, originally developed to study memory retrieval in neural networks, have become versatile tools for modeling diverse biological systems in which function emerges fr…
Collective gene dynamics leave signatures of decision landscapes in cell fate coordinates
Maria Yampolskaya, Laertis Ikonomou, Pankaj Mehta
Multicellular organisms contain a wide variety of highly specialized cell types. The consistency and robustness of developmental trajectories suggest that complex gene regulatory n…
Order-of-Magnitude Beam Current Improvement in Compact Cyclotrons
Daniel Winklehner, Andreas Adelmann, Janet M. Conrad +4
There is great need for high intensity proton beams from compact particle accelerators in particle physics, medical isotope production, and materials- and energy-research. To addre…
First Commissioning Results of the Multicusp Ion Source at MIT (MIST-1) for H
Daniel Winklehner, Spencer Axani, Patrick Bedard +9
IsoDAR is an experiment under development to search for sterile neutrinos using the isotope Decay-At-Rest (DAR) production mechanism, where protons impinging on Be create neutr…
The Isostatic Conjecture
Robert Connelly, Steven J. Gortler, Evan Solomonides +1
We show that a jammed packing of disks with generic radii, in a generic container, is such that the minimal number of contacts occurs and there is only one dimension of equilibrium…
