Inferring short-term volatility indicators from Bitcoin blockchain
Nino Antulov-Fantulin, Dijana Tolic, Matija Piskorec +2
In this paper, we study the possibility of inferring early warning indicators (EWIs) for periods of extreme bitcoin price volatility using features obtained from Bitcoin daily tran…
Underestimated cost of targeted attacks on complex networks
Xiao-Long Ren, Niels Gleinig, Dijana Tolic +1
The robustness of complex networks under targeted attacks is deeply connected to the resilience of complex systems, i.e., the ability to make appropriate responses to the attacks.…
A Nonlinear Orthogonal Non-Negative Matrix Factorization Approach to Subspace Clustering
Dijana Tolic, Nino Antulov-Fantulin, Ivica Kopriva
A recent theoretical analysis shows the equivalence between non-negative matrix factorization (NMF) and spectral clustering based approach to subspace clustering. As NMF and many o…
Simulating SIR processes on networks using weighted shortest paths
Dijana Tolic, Kaj-Kolja Kleineberg, Nino Antulov-Fantulin
We present a framework to simulate SIR processes on networks using weighted shortest paths. Our framework maps the SIR dynamics to weights assigned to the edges of the network, whi…
Cosmological particle creation in a hadronic fluid
Neven Bilic, Dijana Tolic
Acoustic perturbations in an expanding hadronic fluid at temperatures below the chiral transition point represent massless pions propagating in curved spacetime geometry. In comovi…
Analog geometry in an expanding fluid from AdS/CFT perspective
Neven Bilić, Silvije Domazet, Dijana Tolić
The dynamics of an expanding hadron fluid at temperatures below the chiral transition is studied in the framework of AdS/CFT correspondence. We establish a correspondence between t…
FRW universe in the laboratory
Neven Bilic, Dijana Tolic
We consider an expanding relativistic fluid with spherical symmetry as a model for an analog FRW spacetime. In the framework of relativistic acoustic geometry we demonstrate how to…
Trapped surfaces in a hadronic fluid
Neven Bilic, Dijana Tolic
Pion propagation in a hadronic fluid with a non-homogeneous relativistic flow is studied in terms of the linear sigma model. The wave equation turns out to be equivalent to the equ…
Analogue surface gravity near the QCD chiral phase transition
Neven Bilic, Dijana Tolic
Using the formalism of relativistic acoustic geometry we study the expanding chiral fluid in the regime of broken chiral symmetry near the QCD chiral phase transition temperature T…
