Die letzte Danksagung gilt meiner Familie für die private Unterstützung und meiner Liebe Franziska Helm, die stets zu mir gehalten hat und mir das Gefühl gibt, etwas Besonderes zu sein.

Science is a powerful force for change in modern society. As the professionals at its helm, scientists have a unique responsibility to shepherd that change with thoughtful advocacy of their research and careful ethical scrutiny of their own behavior.

F Sellers Collins, who was sworn in as the 16th Director of the National Institutes of Health (NIH) on Monday August 17, 2009, is well acquainted with big projects, big budgets, and big politics. He had previously served as director of the National Human Genome Research Institute (NHGRI) from 1993 to 2008, during which he oversaw the US publically financed arm of the Human Genome Project.1–4 Co...

Stuttering is a common problem in childhood that may persist into adulthood if not treated in early stages. Techniques from spoken language understanding may be applied to provide automated diagnosis of stuttering from children speech. The main challenges however lie in the lack of training data and the high dimensionality of this data. This study investigates the applicability of machine learn...

Abstract. A divisor cordial labeling of a graph G with vertex set V is a bijection f from V to {1, 2,... | |} V such that an edge uv is assigned the label 1 if ( ) | ( ) f u f v or ( ) | ( ) f v f u and the label 0 otherwise, then number of edges labeled with 0 and the number of edges labeled with 1 differ by at most 1. A graph with a divisor cordial labeling is called a divisor cordial graph. ...

A new method of solving the power-flow problem, the holomorphically embedded load-flow method (HELM) is theoretically guaranteed to find the high-voltage solution, if one exists, up to the saddle-node bifurcation point (SNBP), provided sufficient precision is used and the conditions of Stahls theorem are satisfied. Two-bus reduced-order equivalents obtained using HELM-based models, involving si...
