HST/ACS Imaging of Omega Centauri: Optical Counterparts of Chandra X-Ray Sources
Adrienne M. Cool, Daryl Haggard, Tersi Arias +5
We present results of a search for optical counterparts of X-ray sources in and toward the globular cluster Omega Centauri (NGC 5139) using the Advanced Camera for Surveys (ACS) on…
Enumerating Colorings, Tensions and Flows in Cell Complexes
Matthias Beck, Felix Breuer, Logan Godkin +1
We study quasipolynomials enumerating proper colorings, nowhere-zero tensions, and nowhere-zero flows in an arbitrary CW-complex , generalizing the chromatic, tension and flow p…
Universal mechanism of (semi-classical) deconfinement and theta-dependence for all simple groups
Erich Poppitz, Thomas Schaefer, Mithat Unsal
Using the twisted partition function on R^3 x S^1, we argue that the deconfinement phase transition in pure Yang-Mills theory for all simple gauge groups is continuously connected…
Oh sister, where art thou? Spatial population structure and the evolution of an altruistic defence trait
Tobias Pamminger, Susanne Foitzik, Dirk Metzler +1
The evolution of parasite virulence and host defences is affected by population structure. This effect has been confirmed in studies focusing on large spatial scales, whereas the i…
The joint use of the tangential electric field and surface Laplacian in EEG classification
C. G. Carvalhaes, J. Acacio de Barros, M. Perreau-Guimarães +1
This paper discusses the use of the scalp electric field to decode EEG-recorded brain processes. Instead of using bipolar measurements, the scalp electric field is described as a 3…
Topological creation and destruction of edge states in photonic graphene
Mikael C. Rechtsman, Yonatan Plotnik, Julia M. Zeuner +2
We demonstrate theoretically and experimentally a topological transition of classical light in "photonic graphene": an array of waveguides arranged in the honeycomb geometry. As th…
