Characterization of magnetic field noise in the ARIADNE source mass rotor
Nancy Aggarwal, Allard Schnabel, Jens Voigt +19
ARIADNE is a nuclear-magnetic-resonance-based experiment that will search for novel axion-induced spin-dependent interactions between an unpolarized source mass rotor and a nearby…
Propagation of large concentration changes in reversible protein binding networks
Sergei Maslov, I. Ispolatov
We study how the dynamic equilibrium of the reversible protein-protein binding network in yeast Saccharomyces cerevisiae responds to large changes in abundances of individual prote…
Propagation of fluctuations in interaction networks governed by the law of mass action
Sergei Maslov, Kim Sneppen, Iaroslav Ispolatov
Using an example of physical interactions between proteins, we study how perturbations propagate in interconnected networks whose equilibrium state is governed by the law of mass a…
Finding mesoscopic communities in sparse networks
I. Ispolatov, I. Mazo, A. Yuryev
We suggest a fast method to find possibly overlapping network communities of a desired size and link density. Our method is a natural generalization of the finite- superparamegn…
Binding properties and evolution of homodimers in protein-protein interaction networks
Iaroslav Ispolatov, Anton Yuryev, Ilya Mazo +1
We demonstrate that Protein-Protein Interaction (PPI) networks in several eucaryotic organisms contain significantly more self-interacting proteins than expected if such homodimers…
Duplication-divergence model of protein interaction network
I. Ispolatov, P. L. Krapivsky, A. Yuryev
We show that the protein-protein interaction networks can be surprisingly well described by a very simple evolution model of duplication and divergence. The model exhibits a remark…
