The monotypic tropical tree species Hagenia abyssinica (Rosaceae) is an anemogamous and anemochorous broad-leaved dioecious tree species native to Africa. Fossil pollen evidence suggests that it immigrated into Ethiopia from the south during the late Pleistocene. The chloroplast haplotypes identified in Hagenia are grouped into two lineages and demonstrated a strong pattern of congruence between their geographical distribution and genealogical relationships. Restricted gene flow through seeds, contiguous range expansion, mutation and rare long-distance dispersal shaped the genetic structure in the...

The max-cut problem is an NP-hard combinatorial optimization problem defined on undirected weighted graphs. It consists in finding a subset of the graph's nodes such that the aggregate weight of the edges between the subset and its complement is maximized. This book deals with a new separation approach to be used within a branch-and-cut algorithm for solving max-cut problems to optimality. The method is based on graph contraction and allows the fast separation of so-called odd-cycle inequalities. In addition, we...

For the first time in the history of European integration, the Treaty of Lisbon allows a member country to leave the EU without giving a reason. What consequences could the exit option have?

Or will the end of the European integration process be heralded with the now explicit option to leave? Could the right to withdraw...

The problem of publicity when assigning chattels as security is as old as the assignment itself. The loan collateral, which is often used in practice, seems to function smoothly for the most part. A closer look, however, reveals a number of weaknesses and dogmatic distortions due to the lack of publicity. Last but not least, the German security assignment must also be able to be measured in an international perspective. It is precisely here that Germany is largely isolated with...

The subject of the dissertation is the admissibility of restricting the office of insolvency administrator to natural persons in accordance with Section 56 InsO and the resulting exclusion of legal entities from the office of insolvency administrator.
