Computing sets from all infinite subsets
Noam Greenberg, Matthew Harrison-Trainor, Ludovic Patey +1
A set is introreducible if it can be computed by every infinite subset of itself. Such a set can be thought of as coding information very robustly. We investigate introreducible se…
Dynamics of a 2D lattice of van der Pol oscillators with nonlinear repulsive coupling
I. A. Shepelev, S. S. Muni, T. E. Vadivasova
We describe spatiotemporal patterns in a network of identical van der Pol oscillators coupled in a two-dimensional geometry. In this study, we show that the system under study demo…
MOA-2007-BLG-400 A Super-Jupiter Mass Planet Orbiting a Galactic BulgeK-dwarf Revealed by Keck Adaptive Optics Imaging
Aparna Bhattacharya, David P. Bennett, Jean P. Beaulieu +11
We present Keck/NIRC2 adaptive optics imaging of planetary microlensing event MOA-2007-BLG-400 that resolves the lens star system from the source. We find that the MOA-2007-BLG-400…
Chimera states in ring-star network of Chua circuits
S. S. Muni, A. Provata
We investigate the emergence of amplitude and frequency chimera states in ring-star networks consisting of identical Chua circuits connected via nonlocal diffusive, bidirectional c…
Role of solitary states in forming spatiotemporal patterns in a 2D lattice of van der Pol oscillators
I. A. Shepelev, A. V. Bukh, S. S. Muni +1
The behavior of the ensemble of coupled van der Pol oscillators is abundant when coupling parameters are changed. Incoherent and chimera-like regimes are observed at small values o…
OGLE-2018-BLG-1269Lb: A Jovian Planet With A Bright, Host
Youn Kil Jung, Andrew Gould, Andrzej Udalski +54
We report the discovery of a planet in the microlensing event OGLE-2018-BLG-1269, with planet-host mass ratio , i.e., times smaller than the Jupiter/Su…
