Materials and Methods In this institutional review board-approved study, 15 patients with biopsy-proven prostate cancer underwent T₂-weighted magnetic resonance imaging and 3-dimensional ³¹P MRSI at 7 T. Voxels were selected at the tumor location, in normal-appearing peripheral zone tissue, normal-appearing transition zone tissue, and in the base of the prostate close to the seminal vesicles. Phosphorus metabolite ratios were determined and compared between tissue types. Results Signals of phosphoethanolamine (PE) and phosphocholine (PC) were present and well resolved in most ³¹P spectra in the prostate. Glycerophosphocholine signals were observable in 43\% of the voxels in malignant tissue, but in only 10\% of the voxels in normal-appearing tissue away from the seminal vesicles. In many spectra, independent of tissue type, 2 peaks resonated in the chemical shift range of inorganic phosphate, possibly representing 2 separate pH compartments. The PC/PE ratio in the seminal vesicles was highly elevated compared with the prostate in 5 patients. A considerable overlap of ³¹P metabolite ratios was found between prostate cancer and normal-appearing prostate tissue, preventing direct discrimination of these tissues. The only 2 patients with high Gleason scores tumors (≥4+5) presented with high PC and glycerophosphocholine levels in their cancer lesions. Conclusions Phosphorus MRSI at 7 T shows distinct features of phospholipid metabolites in the prostate gland and its surrounding structures. In this exploratory study, no differences in ³¹P metabolite ratios were observed between prostate cancer and normal-appearing prostate tissue possibly because of the partial volume effects of small tumor foci in large MRSI voxels.}, language = {en} } @inproceedings{Huening2014, author = {H{\"u}ning, Felix}, title = {Power semiconductors : key components for HEV/EV}, series = {FISITA 2014 World Automotive Congress : 2 - 6 June, Maastricht, the Netherlands International Federation of Automotive Engineering Societies}, booktitle = {FISITA 2014 World Automotive Congress : 2 - 6 June, Maastricht, the Netherlands International Federation of Automotive Engineering Societies}, publisher = {KIVI}, address = {[s.l.]}, pages = {1 USB-Speicherstick}, year = {2014}, language = {en} } @inproceedings{NeugebauerBrutschyMeyeretal.2014, author = {Neugebauer, Georg and Brutschy, Lucas and Meyer, Ulrike and Wetzel, Susanne}, title = {Privacy-preserving multi-party reconciliation secure in the malicious model}, series = {DPM 2013, SETOP 2013: Data Privacy Management and Autonomous Spontaneous Security}, booktitle = {DPM 2013, SETOP 2013: Data Privacy Management and Autonomous Spontaneous Security}, editor = {Garcia-Alfaro, Joaquin and Lioudakis, Georgios and Cuppens-Boulahia, Nora and Foley, Simon and Fitzgerald, William M.}, publisher = {Springer}, address = {Berlin}, isbn = {978-3-642-54567-2 (Print)}, doi = {10.1007/978-3-642-54568-9_12}, pages = {178 -- 193}, year = {2014}, abstract = {The problem of fair and privacy-preserving ordered set reconciliation arises in a variety of applications like auctions, e-voting, and appointment reconciliation. While several multi-party protocols have been proposed that solve this problem in the semi-honest model, there are no multi-party protocols that are secure in the malicious model so far. In this paper, we close this gap. Our newly proposed protocols are shown to be secure in the malicious model based on a variety of novel non-interactive zero-knowledge-proofs. We describe the implementation of our protocols and evaluate their performance in comparison to protocols solving the problem in the semi-honest case.}, language = {en} } @techreport{LessenichRitzWallenborn2014, author = {Leßenich, Nina and Ritz, Thomas and Wallenborn, Ramona}, title = {Prototyping zur Verbesserung der Benutzerfreundlichkeit mobiler Software : Potenziale benutzerfreundlicher Software-Entwicklung ; Info-Brosch{\"u}re}, publisher = {eBusiness-Lotse}, address = {Aachen}, pages = {7 S. : Ill., graph.

The novel RoboCup Logistics League Sponsored by Festo (LLSF) aims at such CPS logistic scenarios in an automation setting. A team of robots has to produce products from a number of semi-finished products which they have to machine during the game. Different production plans are possible and the robots need to recycle scrap byproducts. This way, the LLSF is a very interesting league offering a number of challenging research questions for planning, coordination, or communication in an application-driven scenario. In this paper, we outline the objectives of the LLSF and present steps for developing the league further towards a benchmark for logistics scenarios for CPS. As a major milestone we present the new automated referee system which helps in governing the game play as well as keeping track of the scored points in a very complex factory scenario.}, language = {en} } @inproceedings{MaikeLenzWolf2014, author = {Maike, M{\"u}ller and Lenz, Laura and Wolf, Martin}, title = {Steigerung der Effektivit{\"a}t durch Prozessmodellierungs-Tools - {\"A}nderbarkeit und Transparenz von Prozessen am Beispiel der Business Simulation Apollo 13}, series = {Informatik 2014}, booktitle = {Informatik 2014}, publisher = {Gesellschaft f{\"u}r Informatik e.V.}, address = {Bonn}, isbn = {978-3-88579-626-8}, issn = {1617-5468}, pages = {357 -- 369}, year = {2014}, abstract = {Die Nutzung von Prozessmodellierungsmethoden oder - werkzeugen kann erheblichen Einfluss auf die Effektivit{\"a}t von Prozessen haben.
