Finding Even Subgraphs Even Faster [PDF]
, 2014 Problems of the following kind have been the focus of much recent research in the realm of parameterized complexity: Given an input graph (digraph) on $n$ vertices and a positive integer parameter $k$, find if there exist $k$ edges (arcs) whose deletion ...

The mechanical origin of snow avalanche dynamics and flow regime transitions [PDF]
The Cryosphere, 2020 Snow avalanches cause fatalities and economic damage. Key to their mitigation is the understanding of snow avalanche dynamics. This study investigates the dynamic behavior of snow avalanches, using the material point method (MPM) and an elastoplastic ...

Lagrangian-Eulerian Methods for Uniqueness in Hydrodynamic Systems
, 2014 We present a Lagrangian-Eulerian strategy for proving uniqueness and local existence of solutions in path spaces of limited smoothness for a class of incompressible hydrodynamic models including Oldroyd-B type complex fluid models and zero magnetic ...

The Coupled Eulerian-Lagrangian Analysis of the KOBO Extrusion Process
, 2021 The KOBO extrusion is an unconventional elastic-plastic deformation process in which the phenomenon of changing a path of plastic deformation due to die cyclic oscillations by a given angle and with a given frequency is applied.

RNA-seq assembly – Are we there yet?
Frontiers in Plant Science, 2012 Transcriptomic sequence resources represent invaluable assets for research, in particular for non-model species without a sequenced genome. To date, the Next Generation Sequencing technologies 454/Roche and Illumina have been used to generate ...

Approximating ATSP by Relaxing Connectivity
, 2015 The standard LP relaxation of the asymmetric traveling salesman problem has been conjectured to have a constant integrality gap in the metric case. We prove this conjecture when restricted to shortest path metrics of node-weighted digraphs. Our arguments

Quasigroups defining Eulerian paths in complete graphs
Journal of Combinatorial Theory, Series B, 1982 AbstractThis paper provides a graph theoretical contribution to the solution of a problem that was so far dealt with purely combinatorial methods: For which values of r does a P-quasigroup exist which defines an Eulerian path in the complete graph K2r + 1?
