Equilibrium and non-equilibrium furanose selection in the ribose isomerisation network
Avinash Vicholous Dass, Thomas Georgelin, Frances Westall +5
The exclusive presence of -D-ribofuranose in nucleic acids is still a conundrum in prebiotic chemistry, given that pyranose species are substantially more stable at equilibrium.…
Diffusion-limited reactions in crowded environments
N. Dorsaz, C. De Michele, F. Piazza +2
Diffusion-limited reactions (DLR) are usually described within the Smoluchowski theory, which neglects interactions between the diffusing components. We propose a first extension o…
Extended navigability of small world networks: exact results and new insights
Cecile Caretta Cartozo, Paolo De Los Rios
Navigability of networks, that is the ability to find any given destination vertex starting from any other vertex, is crucial to their usefulness. In 2000 Kleinberg showed that opt…
Temperature dependence of normal mode reconstructions of protein dynamics
Francesco Piazza, Paolo De Los Rios, Fabio Cecconi
Normal mode analysis is a widely used technique for reconstructing conformational changes of proteins from the knowledge of native structures. In this Letter, we investigate to wha…
Uncovering the topology of configuration space networks
David Gfeller, Paolo De Los Rios, David Morton de Lachapelle +2
The configuration space network (CSN) of a dynamical system is an effective approach to represent the ensemble of configurations sampled during a simulation and their dynamic conne…
The role of clustering and gridlike ordering in epidemic spreading
Thomas Petermann, Paolo De Los Rios
The spreading of an epidemic is determined by the connectiviy patterns which underlie the population. While it has been noted that a virus spreads more easily on a network in which…
Preferential Exchange: Strengthening Connections in Complex Networks
Guido Caldarelli, Fabrizio Coccetti, Paolo De Los Rios
Many social, technological and biological interactions involve network relationships whose outcome intimately depends on the structure of the network and on the strengths of the co…
On the Widespread Occurrence of the Inverse Square Distribution in Social Sciences and Taxonomy
Guido Caldarelli, Cecile Caretta Cartozo, Paolo De Los Rios +1
The widespread occurrence of an inverse square relation in the hierarchical distribution of sub-communities within communities (or sub-species within species) has been recently inv…
The Local Minority Game
Susanne Moelbert, Paolo De Los Rios
Ecologists and economists try to explain collective behavior in terms of competitive systems of selfish individuals with the ability to learn from the past. Statistical physicists…
Discretized Diffusion Processes
Stefano Ciliberti, Guido Caldarelli, Paolo De Los Rios +2
We study the properties of the ``Rigid Laplacian'' operator, that is we consider solutions of the Laplacian equation in the presence of fixed truncation errors. The dynamics of con…
Putting Proteins back into Water
Paolo De Los Rios, Guido Caldarelli
We introduce a simplified protein model where the solvent (water) degrees of freedom appear explicitly (although in an extremely simplified fashion). Using this model we are able t…
Statistical Analysis of Genealogical Trees for Polygamic Species
Paolo De Los Rios, Oscar Pla
Repetitions within a given genealogical tree provides some information about the degree of consanguineity of a population. They can be analyzed with techniques usually employed in…
Levy-Nearest-Neighbors Bak-Sneppen Model
R. Cafiero, P. De Los Rios, A. Valleriani +1
We study a random neighbor version of the Bak-Sneppen model, where "nearest neighbors" are chosen according to a probability distribution decaying as a power-law of the distance fr…
Universality and Crossover of Directed Polymers and Growing Surfaces
Paolo De Los Rios
We study KPZ surfaces on Euclidean lattices and directed polymers on hierarchical lattices subject to different distributions of disorder, showing that universality holds, at odds…
Universal 1/f Noise from Dissipative SOC Models
P. De Los Rios, Y. -C. Zhang
We introduce a model able to reproduce the main features of 1/f noise: hyper-universality (the power-law exponents are independent on the dimension of the system; we show here resu…
Directed Polymers on a Factorized Disorder Landscape
Paolo De Los Rios, Yi-Cheng Zhang
We study the Directed Polymer model subject to a particular form of disorder, , recently proposed in biological applications. We find that two new universalit…
Critical exponents of the anisotropic Bak-Sneppen model
Sergei Maslov, Paolo De Los Rios, Matteo Marsili +1
We analyze the behavior of spatially anisotropic Bak-Sneppen model. We demonstrate that a nontrivial relation between critical exponents tau and mu=d/D, recently derived for the is…
On the High-dimensional Bak-Sneppen model
P. De Los Rios, M. Marsili, M. Vendruscolo
We report on extensive numerical simulations on the Bak-Sneppen model in high dimensions. We uncover a very rich behavior as a function of dimensionality. For d>2 the avalanche clu…
Expansion Around the Mean-Field Solution of the Bak-Sneppen Model
Matteo Marsili, Paolo De Los Rios, Sergei Maslov
We study a recently proposed equation for the avalanche distribution in the Bak-Sneppen model. We demonstrate that this equation indirectly relates ,the exponent for the power l…
