A universal model for mobility and migration patterns
A stochastic process capturing local mobility decisions that helps to derive commuting and mobility fluxes that require as input only information on the population distribution is introduced, significantly improving the predictive accuracy of most of the phenomena affected by mobility and transport processes. Expand
Neutral theory and relative species abundance in ecology
A theoretical framework for the unified neutral theory of biodiversity and an analytical solution for the distribution of the RSA both in the metacommunity (Fisher's log series) and in the local community, where there are fewer rare species. Expand
Global protein function prediction from protein-protein interaction networks
The assignment of proteins to functional classes on the basis of their network of physical interactions as determined by minimizing the number of protein interactions among different functional categories is proposed. Expand
Size and form in efficient transportation networks
The theory accounts in a general way for the quarter-power allometric scaling of living organisms and predicts scaling relations applicable to all efficient transportation networks, which is verified from observational data on the river drainage basins. Expand
Fundamental patterns underlying gene expression profiles: simplicity from complexity.
Simple regularities in the seemingly complex transcriptional transitions of diverse cells to new states are revealed, and these provide insights into the operation of the underlying genetic networks. Expand
Modeling of Protein Interaction Networks
A graph-generating model aimed at representing the evolution of protein interaction networks based on the hypothesis of evolution by duplication and divergence of the genes which produce proteins is introduced. Expand
On Hack's Law
Hack's law is reviewed, emphasizing its implications for the elongation of river basins as well as its connections with their fractal characteristics. The relation between Hack's law and the internalExpand
Density dependence explains tree species abundance and diversity in tropical forests
It is shown that the framework of the current neutral theory in ecology can easily be generalized to incorporate symmetric density dependence and precisely the strength of the rare-species advantage that is needed to explain a given RSA distribution is calculated. Expand
Supply–demand balance and metabolic scaling
It is shown that the ubiquitous 3/4 power law for interspecific metabolic scaling arises from simple, general geometric properties of transportation networks constrained to function in biological organisms. Expand
Insight into the Structure of Amyloid Fibrils from the Analysis of Globular Proteins
The results corroborate the recent hypothesis that the amyloid structure is stabilised by the same physicochemical determinants as those operating in folded proteins and suggest that side chain–side chain interaction across neighbouring β-strands is a key determinant of amyloids fibril formation and of their self-propagating ability.
