Discovery of a Pair of Classical Cepheids in an Invisible Cluster Beyond the Galactic Bulge
I. Dékány, D. Minniti, G. Hajdu +6
We report the discovery of a pair of extremely reddened classical Cepheid variable stars located in the Galactic plane behind the bulge, using near-infrared time-series photometry…
Lines, betweenness and metric spaces
Pierre Aboulker, Xiaomin Chen, Guangda Huzhang +2
A classic theorem of Euclidean geometry asserts that any noncollinear set of points in the plane determines at least distinct lines. Chen and Chvátal conjectured that this…
Variability-selected Active Galactic Nuclei in the VST-SUDARE/VOICE Survey of the COSMOS Field
D. De Cicco, M. Paolillo, G. Covone +16
Optical variability has proven to be an effective way of detecting AGNs in imaging surveys, lasting from weeks to years. In the present work we test its use as a tool to identify A…
Non-minimal fields of the pure spinor string in general curved backgrounds
Osvaldo Chandia, Brenno Carlini Vallilo
We study the coupling of the non-minimal ghost fields of the pure spinor superstring in general curved backgrounds. The coupling is found solving the consistent relations from the…
New Unfolded Higher Spin Systems in
Nicolas Boulanger, Dmitry Ponomarev, Ergin Sezgin +1
We investigate the unfolded formulation of bosonic Lorentz tensor fields of arbitrary spin in containing a parity breaking mass parameter. They include deformations of the…
Allosteric Communication Pathways and Thermal Rectification in PDZ-2 Protein: A Computational Study
Germán A. Miño-Galaz
Allosteric communication in proteins is a central and yet unsolved problem of structural biochemistry. Previous findings, from computational biology (Ota and Agard, 2005), have pro…
