Approximation Algorithms for the Traveling Salesman Problem
(2021-05-11)
The traveling salesman problem (TSP) is probably one of the best-studied problems in discrete optimization. Given a complete weighted graph with n vertices, the task is to find a tour of minimal length that visits every ...
Diversity of feeding and pollination strategies of Mesozoic beetles
(2020-08-23)
Beetles (Order: Coleoptera) as the most diverse and successful animals on the earth, comprise about 400,000 species, constituting almost 40% of described insects and a quarter of all animal species. They are distributed ......
Funktionelle Untersuchungen des ABC-Transporters ABCG2
(2021-10-15)
Das Phänomen der Multidrug Resistance (MDR) stellt ein bedeutsames Problem bei der Behandlung von Tumoren mit Chemotherapeutika dar. Die ABC-Transporter ABCB1, ABCC1 und ABCG2 sind an der Entstehung der MDR beteiligt. ...
In situ observations of reaction and transport phenomena during silicate glass corrosion by fluid-cell Raman spectroscopy: Method development and applications
(2020-07-06)
Borosilicate glass is the preferred material for the immobilization of high-level nuclear waste and an important material for various industries. Silicate glasses, however, are prone to corrosion by aqueous solutions, which ......
Direct lineage programming - a tool to generate and analyze human cortical layer specific neurons
(2020-05-14)
Until recently, lineage commitment and differentiation have been considered to be unidirectional and irreversible. This traditional view has dramatically changed with the advent of cellular reprogramming and direct cell ......
On some Geometric Search Problems: Algorithms, Complexity, Computability
(2020-11-25)
This thesis considers four search problems which are related to or emerge from a geometric context. Each search problem is examined in a separate chapter; these four chapters are framed by an introduction and a conclusion ...
Occlusion and Function of Triconodont Dentitions
(2020-12-18)
Over the last decades, many studies have focused on the tribosphenic molar and its functional aspects because it is considered to be a key innovation in mammalian evolution. Early triconodont dentitions have been examined ...
Concepts of Immune Regulation in Chronic Filarial Infections
(2021-04-21)
Despite worldwide efforts to reduce filariasis, over 100 million individuals still suffer from filarial infections. Filarial infections continue to be a substantial drain at both economic and health levels, especially in ......
The Impact of CD44 and Osteopontin on Hematopoiesis
(2021-10-25)
Hematopoiesis is the process, which enables the replenishment of blood cellular components in mammals throughout their lifespan. Hematopoietic stem cells (HSC), which reside within the bone marrow (BM), are the primary ...
Electrostatic anchoring of SNAP25 to the plasma membrane
(2021-07-21)
Neurotransmission is based on incredibly rapid membrane trafficking cycles, mediating the release of neurotransmitters. The fusion machinery of the well-studied SNARE protein complex ensures the speed and precision of ...
