We show that sparse binary trees represent patterns of gene flow in general pedigrees in a parsimonious manner, and derive a family of related algorithms for pedigree traversal.

A decade ago, people from Salija village in western Nepal traveled several hours into the uphill forests to gather firewood ...

Ahmedabad: Nearly two-thirds (63.4%) of Ahmedabad's 2,670km road network shows very sparse green cover, while nearly a third ...

Sparse ground cover means the threat of fire is greatly reduced, a danger further lessened by the relative paucity of dead bristlecone needles in a landscape where trees are ... a dense, highly ...

Specifically, it falls within a "Goldilocks zone"—not too sparse, and not too dense—that favors strategic thinking and planning ahead, leading to the development of "planning" circuitry in the ...

Second, we utilize sparse-to-dense matching with symmetry of correspondence to implement accurate pixel-level matching, which enables our method to produce more accurate correspondences.
