Universality in percolation of arbitrary Uncorrelated Nested Subgraphs

open access: yes, 2010
The study of percolation in so-called {\em nested subgraphs} implies a generalization of the concept of percolation since the results are not linked to specific graph process. Here the behavior of such graphs at criticallity is studied for the case where

Nested Grid Models for Ocean Processes

open access: yes24th International Conference on Offshore Mechanics and Arctic Engineering: Volume 3, 2005
This paper presents a novel two-way nested grid scheme that allows information to travel freely through the computational boundaries of the grid interface. The method tentatively assumes the pressure boundary conditions between subdomains, but uses a receding boundary approach to minimize the pressure errors.

Experimental evidence that cuckoos preferentially parasitize host nests early in their laying cycle

open access: yesAvian Research, 2022
Brood parasites, such as the Common Cuckoo (Cuculus canorus), rely on manipulating hosts from other species to raise their offspring. Selection should favor individuals that are able to identify and choose host nests that closely match the incubation ...

Strong Connectivity in Directed Graphs under Failures, with Application

open access: yes, 2019
In this paper, we investigate some basic connectivity problems in directed graphs (digraphs). Let $G$ be a digraph with $m$ edges and $n$ vertices, and let $G\setminus e$ be the digraph obtained after deleting edge $e$ from $G$.

The Implications of Nesting in California Redistricting [PDF]

open access: yes, 2007
Evaluates the process of nesting -- aggregating or dividing assembly and senate districts -- on redistricting outcomes, including compactness, minimizing city and county divisions, and the creation of majority minority ...

Tableau sequences, open diagrams, and Baxter families [PDF]

open access: yes, 2015
Walks on Young's lattice of integer partitions encode many objects of algebraic and combinatorial interest. Chen et al. established connections between such walks and arc diagrams.
