Canards at Folded Nodes
Canards Folded Nodes
2015/8/25
Folded singularities occur generically in singularly perturbed systems of differential
equations with two slow variables and one fast variable. The folded singularities can
be saddles, nodes or foci...
Folded nodes occur in generic slow-fast dynamical systems with two slow variables. Open regions
of initial conditions flow into a folded node in an open set of such systems, so folded nodes are an
i...

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...
Canalization in the Critical States of Highly Connected Networks of Competing Boolean Nodes
Competing Boolean Nodes Highly Connected Networks
2011/9/13
Canalization is a classic concept in Developmental Biology that is thought to be an important feature of evolving systems. In a Boolean network it is a form of network robustness in which a subset of ...
Flows in complex biochemical networks: Role of low degree nodes
Flows complex biochemical networks low degree nodes
2011/1/5
Metabolic networks have two properties that are generally regarded as unrelated: One, they have metabolic reactions whose single knockout is lethal for the organism, and two, they have correlated sets...
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...
Robust Simultaneous Localization of Nodes and Targets in Sensor Networks Using Range-Only Measurements
Robust Simultaneous Localization of Nodes Targets in Sensor Networks
2010/12/6
Simultaneous localization and tracking (SLAT) in sensor networks aims to determine the positions of sensor nodes and a moving target in a network, given incomplete and inaccurate range measurements be...
