Confluent Hasse Diagrams [PDF]
Journal of Graph Algorithms and Applications, 2013 We show that a transitively reduced digraph has a confluent upward drawing if and only if its reachability relation has order dimension at most two. In this case, we construct a confluent upward drawing with O(n2) features, in an O(n) ×O(n) grid in O ...

Strict confluent drawing [PDF]
Journal of Computational Geometry, 2016 We define strict confluent drawing, a form of confluent drawing in which the existence of an edge is indicated by the presence of a smooth path through a system of arcs and junctions (without crossings), and in which such a path, if it exists, must be ...

On Quasi-ω-Confluent Mappings [PDF]
International Journal of Mathematics and Mathematical Sciences, 2011 We introduce a new class of mappings called quasi-ω-confluent maps, and we study the relation between these mappings, and some other forms of confluent maps.

On Strict (Outer-)Confluent Graphs [PDF]
Journal of Graph Algorithms and Applications, 2021 A strict confluent (SC) graph drawing is a drawing of a graph with vertices as points in the plane, where vertex adjacencies are represented not by individual curves but rather by unique smooth paths through a planar system of junctions and arcs.

Confluent-Functional solving systems [PDF]
Computer Science Journal of Moldova, 2001 The paper proposes a statistical knowledge-acquision approach. The solving systems are considered, which are able to find unknown structural dependences between situational and transforming variables on the basis of statistically analyzed input ...

Indirect pathological indicators for cardiac sarcoidosis on endomyocardial biopsy [PDF]
Journal of Pathology and Translational Medicine, 2020 Background The definitive pathologic diagnosis of cardiac sarcoidosis requires observation of a granuloma in the myocardial tissue. It is common, however, to receive a “negative” report for a clinically probable case. We would like to advise pathologists

Confluent Layered Drawings [PDF]
Algorithmica, 2005 We combine the idea of confluent drawings with Sugiyama style drawings, in order to reduce the edge crossings in the resultant drawings. Furthermore, it is easier to understand the structures of graphs from the mixed style drawings. The basic idea is to cover a layered graph by complete bipartite subgraphs (bicliques), then replace bicliques with tree ...

Preparation of pre-confluent retinal cells increases graft viability in vitro and in vivo: a mouse model. [PDF]
PLoS ONE, 2011 PURPOSE: Graft failure remains an obstacle to experimental subretinal cell transplantation. A key step is preparing a viable graft, as high levels of necrosis and apoptosis increase the risk of graft failure.

Confluent conformal blocks of the second kind
Journal of High Energy Physics, 2020 We construct confluent conformal blocks of the second kind of the Virasoro algebra. We also construct the Stokes transformations which map such blocks in one Stokes sector to another. In the BPZ limit, we verify explicitly that the constructed blocks and
