The determination of the morphology of galaxy clusters has important repercussions for cosmological and astrophysical studies of them. In this paper, we address the morphological characterization of synthetic maps of the Sunyaev–Zel’dovich (SZ) effect for a sample of 258 massive clusters.
Photoheating associated with reionization suppressed star formation in low-mass galaxies. Reionization was inhomogeneous, however, affecting different regions at different times.
The memory hierarchy has a high impact on the performance and power consumption in the system. Moreover, current embedded systems, included in mobile devices, are specifically designed to run multimedia applications, which are memory intensive.
At the end of 2017, Vijaykrishnan Nayaranan, Distinguished Professor of Computer Science and Engineering and Electrical Engineering at Pennsylvania State University, USA, completed his four-year service as the Editor-in-Chief (EIC) for the IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems (TCAD).
We study an extension of the Lotka–Volterra competition model in which one of the competing species avoids encounters with rivals by means of chemorepulsion—a repulsive reaction to the scent of competitors. The evolution of the species densities is described in terms of parabolicequations with cross-diffusive and competitive terms.
We find a series of topological phase transitions of increasing order, beyond the more standard second-order phase transition in a one-dimensional topological superconductor.
