To properly model observed spectra of massive star winds it is necessary to incorporate the 3-D nature of clumping into radiative transfer calculations. In this paper we present our full 3-D Monte Carlo radiative transfer code for inhomogeneous expanding stellar winds. We use a set of parameters to describe dense as well as the rarefied wind components. At the same time, we account for non-monotonic velocity fields. We show how the 3-D density and velocity wind inhomogeneities strongly affect the resonance line formation. We also show how wind clumping can solve the discrepancy between P v and H alpha mass-loss rate diagnostics.}, language = {en} } @misc{LevermannPetoukhovScheweetal.2016, author = {Levermann, Anders and Petoukhov, Vladimir and Schewe, Jacob and Schellnhuber, Hans Joachim}, title = {Abrupt monsoon transitions as seen in paleorecords can be explained by moisture-advection feedback}, series = {Proceedings of the National Academy of Sciences of the United States of America}, volume = {113}, journal = {Proceedings of the National Academy of Sciences of the United States of America}, publisher = {National Acad. of Sciences}, address = {Washington}, issn = {0027-8424}, doi = {10.1073/pnas.1603130113}, pages = {E2348 -- E2349}, year = {2016}, language = {en} } @misc{BuergerMagdansGies2016, author = {B{\"u}rger, Andreas and Magdans, Uta and Gies, Hermann}, title = {Adsorption of amino acids on the magnetite-(111)-surface: a force field study (vol 19, 851, 2013)}, series = {Journal of molecular modeling}, volume = {22}, journal = {Journal of molecular modeling}, publisher = {Springer}, address = {New York}, issn = {1610-2940}, doi = {10.1007/s00894-016-3124-8}, pages = {3}, year = {2016}, language = {en} } @misc{Metzler2017, author = {Metzler, Ralf}, title = {Anomalous Diffusion in Membranes and the Cytoplasm of Biological Cells}, series = {Biophysical journal}, volume = {112}, journal = {Biophysical journal}, number = {3}, publisher = {Cell Press}, address = {Cambridge}, issn = {0006-3495}, doi = {10.1016/j.bpj.2016.11.2577}, pages = {476A -- 476A}, year = {2017}, language = {en} } @misc{Frieler2006, author = {Frieler, Katja}, title = {Beitrag zum Theoretischen Verst{\"a}ndnis polarer stratosph{\"a}rischer Ozonverluste : Modellrechnungen basierend auf Labormessungen und in situ Beobachtungen}, address = {Potsdam}, pages = {182 S. : graph.

The degree of correlation between the mean bubble size and the model parameters is estimated for this purpose for three different DNA sequences. The analysis leads us to a better understanding of the sequence dependent nature of the breathing dynamics of hetero-polymeric DNA. Out of the 14 model parameters for DNA stability in the statistical Poland-Scheraga approach, the hydrogen bond interaction epsilon(hb)(AT) for an AT base pair and the ring factor. turn out to be the most sensitive parameters. In addition, the stacking interaction epsilon(st)(TA-TA) for an TA-TA nearest neighbor pair of base-pairs is found to be the most sensitive one among all stacking interactions. Moreover, we also establish that the nature of stacking interaction has a deciding effect on the DNA breathing dynamics, not the number of times a particular stacking interaction appears in a sequence. We show that the sensitivity analysis can be used as an effective measure to guide a stochastic optimization technique to find the kinetic rate constants related to the dynamics as opposed to the case where the rate constants are measured using the conventional unbiased way of optimization.}, language = {en} } @misc{Zen2006, author = {Zen, Achmad}, title = {Charge Transport in Poly(3-hexylthiophene) and in Highly Soluble Obligothiophene Field-Effect Transistors}, address = {Potsdam}, pages = {150 Bl. : graph.

This study, however, refers to a single point in the space of kinetic parameters of the original Gray-Scott model. Here we show that the wealth of patterns increases substantially as some of these parameters are changed. In addition to spatiotemporal intermittency, defect-mediated turbulence can also be found. In all cases, however, the chaotic behavior is seen to disappear as the advective flow is increased, following a scenario similar to what was reported in our earlier work [I. Berenstein and C. Beta, Phys. Rev. E 86, 056205 (2012)] as well as by Das.

For electrical-insulation applications, on the other hand, a quasi-permanent space charge or dipole polarization is usually considered detrimental. In recent years, however, with the advent of high-voltage direct-current (HVDC) transmission and high-voltage capacitors for energy storage, new possibilities are being explored in the area of high-voltage dielectrics. Stable charge trapping (as e.g. found in nano-dielectrics) or large dipole polarizations (as e.g. found in relaxor ferroelectrics and high-permittivity dielectrics) are no longer considered to be necessarily detrimental in electrical-insulation materials. On the other hand, recent developments in electro-electrets (dielectric elastomers), i.e. very soft dielectrics with large actuation strains and high breakdown fields, and in ferroelectrets, i.e. polymers with electrically charged cavities, have resulted in new electret materials that may also be useful for HVDC insulation systems. Furthermore, 2-dimensional (nano-particles on surfaces or interfaces) and 3-dimensional (nano-particles in the bulk) nano-dielectrics have been found to provide very good charge-trapping properties that may not only be used for more stable electrets and ferroelectrets, but also for better HVDC electrical-insulation materials with the possibility to optimize charge-transport and field-gradient behavior. In view of these and other recent developments, a first attempt will be made to review a small selection of electro-active (i.e. electret) and electro-passive (i.e. insulation) dielectrics in direct comparison. Such a comparative approach may lead to synergies in materials concepts and research methods that will benefit both areas. Furthermore, electrets may be very useful for sensing and monitoring applications in electrical-insulation systems, while high-voltage technology is essential for more efficient charging and poling of electret materials.}, language = {en} } @misc{JavanainenMartinezSearaMetzleretal.2017, author = {Javanainen, Matti and Martinez-Seara, Hector and Metzler, Ralf and Vattulainen, Ilpo Tapio}, title = {Diffusion of Proteins and Lipids in Protein-Rich Membranesa}, series = {Biophysical journal}, volume = {114}, journal = {Biophysical journal}, number = {3}, publisher = {Cell Press}, address = {Cambridge}, issn = {0006-3495}, doi = {10.1016/j.bpj.2017.11.3009}, pages = {551A -- 551A}, year = {2017}, language = {en} }
