Global aspects of the renormalization group and the Hierarchy problem
, 2017 The discovery of the Higgs boson by the ATLAS and CMS collaborations allowed us to precisely determine its mass being 125.09 $\pm$ 0.24GeV. This value is intriguing as it lies at the frontier between the regions of stability and meta-stability of the ...

Topological gravity and transgression holography
, 2014 We show that Poincare-invariant topological gravity in even dimensions can be formulated as a transgression field theory in one higher dimension whose gauge connections are associated to linear and nonlinear realizations of the Poincare group ISO(d-1,1).

Network Structure, Metadata, and the Prediction of Missing Nodes and Annotations
Physical Review X, 2016 The empirical validation of community detection methods is often based on available annotations on the nodes that serve as putative indicators of the large-scale network structure. Most often, the suitability of the annotations as topological descriptors

A collective perception model for neighbor selection in groups based on visual attention mechanisms
New Journal of PhysicsThe mechanisms by which individuals visually perceive and select others within a group to interact with are of fundamental importance to various collective motion behaviors.

Integration of gene expression data with prior knowledge for network analysis and validation
BMC Research Notes, 2011 Background Reconstruction of protein-protein interaction or metabolic networks based on expression data often involves in silico predictions, while on the other hand, there are unspecific networks of in vivo interactions derived from knowledge bases.

, 2009 For monopoles with nonvanishing Higgs potential it is shown that with respect to "Brandt-Neri-Coleman type" variations (a) the stability problem reduces to that of a pure gauge theory on the two-sphere (b) each topological sector admits one, and only one,

Variable sets over an algebra of lifetimes: a contribution of lattice theory to the study of computational topology [PDF]
, 2015 A topos theoretic generalisation of the category of sets allows for modelling spaces which vary according to time intervals. Persistent homology, or more generally, persistence is a central tool in topological data analysis, which examines the structure ...

ESTimating plant phylogeny: lessons from partitioning
BMC Evolutionary Biology, 2006 Background While Expressed Sequence Tags (ESTs) have proven a viable and efficient way to sample genomes, particularly those for which whole-genome sequencing is impractical, phylogenetic analysis using ESTs remains difficult.
