TL;DR: A new 3-hop indexing scheme for directed graphs with higher density over dense DAGs with minimum index size is proposed and an efficient algorithm is developed to discover a transitive closure contour, which yields near optimal index size.
Abstract: Reachability queries on large directed graphs have attracted much attention recently. The existing work either uses spanning structures, such as chains or trees, to compress the complete transitive closure, or utilizes the 2-hop strategy to describe the reachability. Almost all of these approaches work well for very sparse graphs. However, the challenging problem is that as the ratio of the number of edges to the number of vertices increases, the size of the compressed transitive closure grows very large. In this paper, we propose a new 3-hop indexing scheme for directed graphs with higher density. The basic idea of 3-hop indexing is to use chain structures in combination with hops to minimize the number of structures that must be indexed. Technically, our goal is to find a 3-hop scheme over dense DAGs (directed acyclic graphs) with minimum index size. We develop an efficient algorithm to discover a transitive closure contour, which yields near optimal index size. Empirical studies show that our 3-hop scheme has much smaller index size than state-of-the-art reachability query schemes such as 2-hop and path-tree when DAGs are not very sparse, while our query time is close to path-tree, which is considered to be one of the best reachability query schemes.

TL;DR: The Kosi River shifts laterally over the Himalaya foreland plain by continual minor cutoffs and bank cutting and by episodic major shifts across watersheds, by moving into and then out of preexisting, adjacent, less actively aggrading streams.
Abstract: The Kosi River shifts laterally over the Himalaya foreland plain by continual minor cutoffs and bank cutting and by episodic major shifts across watersheds, by moving into and then out of preexisting, adjacent, less actively aggrading streams. Migration is unidirectional because after a channel is filled to instability, floodwater will drain preferentially into a new adjacent low rather than across it to the next watershed or back to the last abandoned channel. Major shifts seem stochastic and autocyclic; they do not correlate with the many severe quakes and floods that undoubtedly helped prime the system for shifts.

TL;DR: Calcanei from African apes, modern humans, and Australopithecus afarensis are compared to investigate the anatomical and mechanical changes that occurred in this bone as a result of the transition to terrestrial bipedality.
Abstract: Calcanei from African apes, modern humans, and Australopithecus afarensis are compared to investigate the anatomical and mechanical changes that occurred in this bone as a result of the transition to terrestrial bipedality. Features analyzed include the cross-sectional area and volume of the calcaneal tuber, the geometry and orientation of the articular surfaces, and the surface topography of the calcaneal corpus. Calcaneal morphology is unequivocal in its partitioning of quadrupedal pongids and bipedal hominids.
