Although 2-opt is widely used in practice, it is hard to understand its success from a theoretical perspective. We take a statistical approach and examine the features of TSP instances that make the problem either hard or easy to solve. As a measure of problem difficulty for 2-opt we use the approximation ratio that it achieves on a given instance. Our investigations point out important features that make TSP instances hard or easy to be approximated by 2-opt.}}, author = {{Mersmann, Olaf and Bischl, Bernd and Bossek, Jakob and Trautmann, Heike and Wagner, Markus and Neumann, Frank}}, booktitle = {{Revised Selected Papers of the 6th International Conference on Learning and Intelligent Optimization - Volume 7219}}, isbn = {{978-3-642-34412-1}}, keywords = {{2-opt, Classification, Feature Selection, MARS, TSP}}, pages = {{115–129}}, publisher = {{Springer-Verlag}}, title = {{{Local Search and the Traveling Salesman Problem: A Feature-Based Characterization of Problem Hardness}}}, year = {{2012}}, } @inbook{53496, author = {{Englisch, Brigitte}}, booktitle = {{Proceedings of the 4.

Therefore, we hypothesized that they also differ in their capacity to undergo epithelial to mesenchymal alterations. Results: We used cultures of freshly isolated primary human tubular cells. To distinguish cells of different tubular origin we took advantage of the fact that human proximal epithelial cells uniquely express N-cadherin instead of E-cadherin as major cell-cell adhesion molecule. To provoke mesenchymal alteration we treated these cocultures with TGF-$\beta$ for up to 6 days. Within this time period, the morphology of distal tubular cells was barely altered. In contrast to tubular cell lines, E-cadherin was not down-regulated by TGF-$\beta$, even though TGF-$\beta$ signal transduction was initiated as demonstrated by nuclear localization of Smad2/3. Analysis of transcription factors and miRNAs possibly involved in E-cadherin regulation revealed high levels of miRNAs of the miR200-family, which may contribute to the stability of E-cadherin expression in human distal tubular epithelial cells. By contrast, proximal tubular epithelial cells altered their phenotype when treated with TGF-$\beta$. They became elongated and formed three-dimensional structures. Rho-kinases were identified as modulators of TGF-$\beta$-induced morphological alterations. Non-specific inhibition of Rho-kinases resulted in stabilization of the epithelial phenotype, while partial effects were observed upon downregulation of Rho-kinase isoforms ROCK1 and ROCK2. The distinct reactivity of proximal and distal cells was retained when the cells were cultured as polarized cells. Conclusions: Interference with Rho-kinase signaling provides a target to counteract TGF-$\beta$-mediated mesenchymal alterations of epithelial cells, particularly in proximal tubular epithelial cells. Furthermore, primary distal tubular cells differed from cell lines by their high phenotypic stability which included constant expression of E-cadherin. Our cell culture system of primary epithelial cells is thus suitable to understand and modulate cellular remodeling processes of distinct tubular cells relevant for human renal disease.}}, author = {{Keller, Christof and Kroening, Sven and Zuehlke, Jonathan and Kunath, Frank and Krueger, Bettina and Goppelt-Struebe, Margarete}}, issn = {{1932-6203}}, journal = {{PLOS ONE}}, number = {{8}}, pages = {{e43584}}, publisher = {{Public Library of Science}}, title = {{{Distinct Mesenchymal Alterations in N-Cadherin and E-Cadherin Positive Primary Renal Epithelial Cells}}}, doi = {{10.1371/journal.pone.0043584}}, volume = {{7}}, year = {{2012}}, } @inproceedings{38331, author = {{Hussin, Saleh and Puntsri, Kidsanapong and Noé, Reinhold}}, booktitle = {{17TH EUROPEAN CONFERENCE ON NETWORK AND OPTICAL COMMUNICATIONS (NOC 2012) AND 7TH CONFERENCE ON OPTICAL CABLING AND INFRASTRUCTURE (OC&I 2012)}}, editor = {{MasipBruin, X and MarinTordera, E and Jukan, A and Faulkner, D and Spalter, S and Munoz, R}}, isbn = {{978-1-4673-0951-6}}, issn = {{2381-3563}}, title = {{{Performance Analysis of RF-Pilot Phase Noise Compensation Techniques in Coherent Optical OFDM Systems}}}, year = {{2012}}, } @article{24713, author = {{Mahnken, Rolf and Shaban, A.}}, issn = {{0939-1533}}, journal = {{Archive of Applied Mechanics}}, pages = {{53--71}}, title = {{{Finite elasto-viscoplastic modeling of polymers including asymmetric effects}}}, doi = {{10.1007/s00419-012-0632-6}}, year = {{2012}}, } @inproceedings{38381, author = {{Hussin, Saleh and Puntsri, Kidsanapong and Noé, Reinhold}}, booktitle = {{17TH EUROPEAN CONFERENCE ON NETWORK AND OPTICAL COMMUNICATIONS (NOC 2012) AND 7TH CONFERENCE ON OPTICAL CABLING AND INFRASTRUCTURE (OC&I 2012)}}, editor = {{MasipBruin, X and MarinTordera, E and Jukan, A and Faulkner, D and Spalter, S and Munoz, R}}, isbn = {{978-1-4673-0951-6}}, issn = {{2381-3563}}, title = {{{Performance Analysis of RF-Pilot Phase Noise Compensation Techniques in Coherent Optical OFDM Systems}}}, year = {{2012}}, } @inproceedings{17226, author = {{Szufnarowska, Joanna and Nomikou, Iris and Rohlfing, Katharina}}, title = {{{Educating each other's attention: Mothers' and infants' eye-contact within natural interactions at 3 and 6 months of age.}}}, year = {{2012}}, } @article{40806, abstract = {{This work reports on the implementation of different absorption micro-filters based on a dye-doped hybrid organic-inorganic xerogel polymeric material synthesized by the sol-gel process. Microstructures containing eight different filter widths were fabricated in polydimethylsiloxane (PDMS), bonded to glass substrates and filled with the corresponding dye doped polymeric material by a soft lithography approach. The filtering capacity as a function of dye concentration and filter width was studied and revealed a linear dependence with both parameters, as expected according to the Beer-Lambert law. Zero passband transmittance values and relatively sharp stopband regions were achieved with all the filters, also showing rejection levels between ?6 dB and ?55 dB. Finally, such filters were monolithically integrated into a disposable fluorescence-based photonic lab-on-a-chip (PhLoC) approach. Calibration curves carried out with a model fluorophore target analyte showed an over two-fold increase in sensitivity and a thirty-fold decrease of the limit of detection (LOD) compared with the values recorded using the same PhLoC system but without the polymeric filter structure. The results presented herein clearly indicate the feasibility of these xerogel-based absorbance filtering structures for being applied as low-cost optical components that can be easily incorporated into disposable fluorescence-based photonic lab on a chip systems}}, author = {{Carregal-Romero, Ester and Fernandez-Sanchez, Cesar and Eguizabal, Alma and Demming, Stefanie and Büttgenbach, Stephanus and Llobera, Andreu}}, journal = {{Opt.
