This paper describes the “motion” properties of the ambiyopic fovea and compares them to the normal periphery. Specifically, thresholds for defection of the displacement of a grating pattern, and for discrimination of displacement direction were measured. The main findings of these experiments were: (I) in the central vision of both normal and amblyopic observers, unreferenced displacements are...

The eukaryotic genome is organized in a manner that allows folding of the genetic material in the confined space of the cell nucleus, while at the same time enabling its physiological function. A major principle of spatial genome organization is the non-random position of genomic loci relative to other loci and to nuclear bodies. The mechanisms that determine the spatial position of a locus, an...

We introduce a heterogeneous connection model for network formation to capture the effect of cost heterogeneity on the structure of efficient networks. In the proposed model, connection costs are assumed to be separable, which means the total connection cost for each agent is uniquely proportional to its degree. For these sets of networks, we provide the analytical solution for the efficient ne...

I suggest that the core ideas of Kit Fine’s Semantic Relationism are the notion of semantic requirement and the notion of manifest consequence, the non-classical logical relation associated with semantic requirement. Surrounding this core are novel “relational” systems of coordinated sequences of expressions, relational (as opposed to intrinsic) semantic values, coordinated propositions, and co...

We use the linear threshold model to study the diffusion of information on a network generated by the stochastic block model. We focus our analysis on a two-community structure where the initial set of informed nodes lies only in one of the two communities and we look for optimal network structures, i.e., those maximizing the asymptotic extent of the diffusion. We find that, constraining the me...

Core-periphery detection is a key task in exploratory network analysis where one aims to find core, set of nodes well connected internally and with the periphery, only (or mostly) core. In this work we propose model core-periphery for higher-order networks modeled as hypergraphs, method computing core-score vector that quantifies how close each node particular, show solves corresponding nonconv...
