Six previously undescribed microorganisms capable of atrazine degradation were isolated from an agricultural soil that received repeated exposures of the commonly used herbicides atrazine and acetochlor. These isolates are all Gram-positive and group with microorganisms in the genera Nocardioides and Arthrobacter, both of which contain previously described(More)
To support the reliability assessment of safety-relevant distributed automotive systems and reduce its complexity, this paper presents a novel approach that extends virtual prototyping towards error effect simulation. Besides the common functional and timed system simulation, error injection is used to stress error tolerance mechanisms. A quantitative(More)
In this paper, a novel approach for integrating static non-preemptive software scheduling in formal bottom-up performance evaluation of embedded system models is described. The presented analysis methodology uses a functional SystemC implementation of communicating processes as input. Necessary model extensions towards capturing of static non-preemptive(More)
Human embryonic stem cells (hESCs) have the potential to serve as a repository of cells for the replacement of damaged or diseased tissues and organs. However, to use hESCs in clinically relevant scenarios, a large number of cells are likely to be required. The aim of this study was to demonstrate an alternative cell culture method to increase the quantity(More)
PURPOSE To ensure the efficiency and safety of transplanted human embryonic stem cell (hESC)-derived osteoblast-like cells (hESC-OS) for bone regeneration, this study was designed to determine the effects of continuous cell expansion on the osteoblastic differentiation stability, pluripotency, and tumorigenic potential of long-term expanded hESC-OS.

In this paper, a novel approach for integrating time slice based resource access in global performance analysis of distributed real-time critical embedded systems is presented. The performance analysis approach itself is based on bottom-up analysis of communicating processes under consideration of synchronization by inter-process communication and complex(More)
We present an approach for the extraction of computational demand of embedded software components and the determination of initial mapping configurations on modern embedded heterogeneous processor architectures. The presented work combines the advantages of component-based design and properties obtained from source-code analysis. The goal is a very fast(More)
We present an approach for the determination of initial mapping configurations for embedded software components on modern embedded heterogeneous processor architectures. The presented work combines the advantages of component-based design and properties obtained from source-code analysis. The goal is a very fast estimation of execution costs for multiple(More)
