This system paper documents the technical foundations for the extension of the Topology ToolKit (TTK) to distributed-memory parallelism with the Message Passing Interface (MPI). While several recent papers introduced topology-based approaches for distributed-memory environments, these were reporting experiments obtained with tailored, mono-algorithm implementations. In contrast, we describe in this paper a versatile approach (supporting both triangulated domains and regular grids) for the support of topological analysis pipelines, i.

Over the last decade merge trees have been proven to support a plethora of visualization and analysis tasks since they effectively abstract complex datasets. This paper describes the ExTreeM-Algorithm: A scalable algorithm for the computation of merge trees via extremum graphs. The core idea of ExTreeM is to first derive the extremum graph G of an input scalar field f defined on a cell complex K, and subsequently compute the unaugmented merge tree of f on G instead of K; which are equivalent.

The unique wounding characteristics of the IED, the portability of the weapon platform, and the relative low cost of development make it an ideal weapon for potential terrorist attacks. If potential future terrorist attacks in the United States follow the same pattern as the incidents currently unfolding in the Middle East, civilian practitioners will be required to manage these wounds early for primary surgical intervention and late for secondary and tertiary reconstructive efforts.

Penetrating, perforating, and avulsive fragmentation injuries present a unique surgical challenge for oral and maxillofacial surgeons in the Iraqi theater of operation. Maxillofacial injuries encountered in Operation Iraqi Freedom I and Operation Iraqi Freedom II have presented injury patterns not encountered previously in other large-scale armed conflicts. Current literature in the field of oral and maxillofacial surgery does not cover adequately the concerns that are inherent to care and treatment planning at an echelon III facility.
