Abstract: A family of algebraic surfaces with many nondegenerate real singularities is introduced with the help of a construction that has been used in previous works for the generation of substitutio...
Uncovering Evolutionary Ages of Nodes in Complex Networks
Uncovering Evolutionary Ages Nodes Complex Networks
2011/8/3
Abstract: In a complex network, different groups of nodes may have existed for different amounts of time. To detect the evolutionary history of a network is of great importance. We present a general m...
We present a network model in which words over a specific alphabet, called {\it structures}, are associated to each node and undirected edges are added depending on some distance between different st...
Calorimetric Evidence for Nodes in the Overdoped Ba(Fe$_{0.9}$Co$_{0.1}$)$_{2}$As$_{2}$
Calorimetric Evidence
2010/11/25
We present low-temperature specific heat of the electron-doped Ba(Fe0.9Co0.1)2As2, which does
not show any indication of an upturn down to 400 mK, the lowest measuring temperature. The
lack of a Sch...
