Energieforschungsprogramms. Im Projekt MAGGIE sollten beispielhaft f{\"u}r das genossenschaftliche historische Stadtquartier „Margaretenau" in Regensburg Musterl{\"o}sungen f{\"u}r energieoptimiertes Wohnen mit innovativen Wandauauten aus solaraktiven Baustoen und einer vorhersagebasierten Versorgungstechnologie entwickelt werden. F{\"u}r ein bestehendes Wohngeb{\"a}ude als Demonstrationsund Versuchsobjekt wurde beispielhaft ein neuartiges, besonders ezientes Hybridsystem aus W{\"a}rmepumpentechnologie und Kraft-W{\"a}rme-Kopplung (Blockheizkraftwerk) konzipiert und umgesetzt. F{\"u}r die denkmalgerechte Modernisierung historischer Fassaden wurde ein solaraktives und solaradaptives Außenputzsystem entwickelt und getestet. Der erh{\"o}hte Ausnutzungsgrad solarer Gewinne in Verbindung mit einer verbesserten thermischen Behaglichkeit im Geb{\"a}udeinnerendurch innovative Innenputz-/Innenfarbsysteme kann maßgeblich zur Einsparung von Heizw{\"a}rme beitragen. Dazu wurden mit Blick auf die bauphysikalischen und w{\"a}rmetechnischen Eigenschaften Versuche an einem eigens aufgebauten Wandpr{\"u}fstand durchgef{\"u}hrt, erg{\"a}nzt durch bauphysikalische Modellsimulationen. Die Ergebnisse sind vielversprechend, auch wenn eine serientaugliche L{\"o}sung f{\"u}r den Einsatz am Geb{\"a}ude im Rahmen des Projektes nicht entstehen konnte. Das wichtigste Ziel des Projektes war es, ein hochezientes, skalierbares Versorgungssystem durch die Kombination von Kraft-W{\"a}rme-Kopplung (Blockheizkraftwerk, BHKW) mit einer Pvunterst{\"u}tzten W{\"a}rmepumpen-Technologie zu entwickeln und im Detail zu modellieren, in Verbindung mit einer innovativenW{\"a}rmelogistik zur Reduktion der Verteilungsverluste f{\"u}r dieWarm-wasserversorgung. Das Systemsollte neben einem hohen Eigenstrom-Nutzungsanteil auch netzdienliche Schwarmfunktionalit{\"a}t aufweisen. Die Skalierbarkeit des vernetzten Systems („Mitwachsen") erlaubt eine abschnittsweise Modernisierung des gesamten Ensembles {\"u}ber mehrere Jahre, was f{\"u}r die Finanzierbarkeit und praktische Umsetzung erhebliche Bedeutung hat. Durch die hohe Energieezienz wird die Warmmiete f{\"u}r die Bewohner der genossenschaftlichen Siedlung durch die Modernisierungsmaßnahmen nicht erh{\"o}ht, so dass auch nach der Modernisierung ein bezahlbares Wohnen sichergestellt wird. Die Auslegung des Systems erfolgte durch ein neu entwickeltes, generisch einsetzbares Planungs-, Optimierungs- und Steuerungstool, das auch die Regelung im Betrieb {\"u}bernimmt. Die in Echtzeit laufende Nachoptimierung des Systems w{\"a}hrend des Betriebs greift auf reale Monitoringdaten zu. Die Einbindung von Nutzerbedarfsprolen, Stromb{\"o}rse und Wetterdaten in die Steuerung ist vorbereitet und gestattet einen dynamischen und perspektivischen Anlagenbetrieb zur Maximierung der Solar- und Umweltw{\"a}rme-Anteile der Energieversorgung. Mithilfe einer intensiven Nutzerinformation in einem partizipativen Planungsprozess wurde die Akzeptanz der experimentellen Maßnahmen sichergestellt.

Here we show that the four peroxygenases AaeUPO, MroUPO, rCciUPO and rNOVO catalyze the stepwise hydroxylation of cyclohexane to cyclohexanol and cyclohexanone. The catalytic efficiencies (kcat/Km) for the initial hydroxylation were in the same order of magnitude for all four peroxygenases (∼104 M-1 s-1), whereas they differed in the second step. The conversion of cyclohexanol by AaeUPO and rCciUPO was 1-2 orders of magnitude less efficient (∼102 M-1 s-1) than by MroUPO and rNOVO (∼104 M-1 s-1). The highest conversion rate in terms of H2O2 utilization was accomplished by MroUPO under repeated addition of the peroxide (87\% in relation to the total products formed). Using the latter UPO, we successfully established a micro-mixing reaction device (SIMM-V2) for the oxidation of cyclohexane. As cyclohexanone is a chemical of high relevance, for example, as starting material for polymer syntheses or as organic solvent, new enzymatic production pathways for this compound are of interest to complement existing chemical and biotechnological approaches. Stable and versatile peroxygenases, as those presented here, may form a promising biocatalytic platform for the development of such enzyme-based processes.}, language = {en} } @incollection{SelkaBaierKurz, author = {Selka, Sebastian and Baier, Daniel and Kurz, Peter}, title = {The Validity of Conjoint Analysis: An Investigation of Commercial Studies Over Time}, series = {Data Analysis, Machine Learning and Knowledge Discovery}, booktitle = {Data Analysis, Machine Learning and Knowledge Discovery}, editor = {Spiliopoulou, Myra and Schmidt-Thieme, Lars and Janning, Ruth}, publisher = {Springer}, address = {Heidelberg-Berlin}, isbn = {978-3-319-01595-8}, pages = {227 -- 234}, language = {en} } @inproceedings{WilczekTrieschmannSchulzeetal., author = {Wilczek, Sebastian and Trieschmann, Jan and Schulze, Julian and Sch{\"u}ngel, Edmund and Brinkmann, Ralf Peter and Derzsi, Aranka and Korolov, Ihor and Donk{\´o}, Zolt{\´a}n and Mussenbrock, Thomas}, title = {Confinement of highly energetic electron beams in low pressure capacitive discharges}, series = {Plasma Sciences (ICOPS), 2015 IEEE International Conference on, May 24-28, 2015, Antalya, Turkey}, booktitle = {Plasma Sciences (ICOPS), 2015 IEEE International Conference on, May 24-28, 2015, Antalya, Turkey}, publisher = {IEEE}, address = {Piscataway, NJ}, isbn = {978-1-4799-6974-6}, doi = {10.1109/PLASMA.2015.7179545}, language = {en} } @inproceedings{WilczekBrinkmannMussenbrock, author = {Wilczek, Sebastian and Brinkmann, Ralf Peter and Mussenbrock, Thomas}, title = {Nonlinear electron resonance heating in asymmetric capacitive discharges}, series = {2016 IEEE International Conference on Plasma Science (ICOPS), Banff, Canada, June 19-23, 2016}, booktitle = {2016 IEEE International Conference on Plasma Science (ICOPS), Banff, Canada, June 19-23, 2016}, publisher = {IEEE}, address = {Piscataway, NJ}, isbn = {978-1-4673-9601-1}, doi = {10.1109/PLASMA.2016.7534107}, language = {en} } @inproceedings{WilczekTrieschmannBrinkmannetal., author = {Wilczek, Sebastian and Trieschmann, Jan and Brinkmann, Ralf Peter and Mussenbrock, Thomas and Schulze, Julian and Sch{\"u}ngel, Edmund and Derzsi, Aranka and Korolov, Ihor and Hartmann, Paul and Donk{\´o}, Zolt{\´a}n}, title = {Hysteresis effects and confinement of beam electrons in capacitive discharges}, series = {2016 IEEE International Conference on Plasma Science (ICOPS), Banff, Canada, June 19-23, 2016}, booktitle = {2016 IEEE International Conference on Plasma Science (ICOPS), Banff, Canada, June 19-23, 2016}, publisher = {IEEE}, address = {Piscataway, NJ}, isbn = {978-1-4673-9601-1}, doi = {10.1109/PLASMA.2016.7534342}, language = {en} } @inproceedings{PeterHoffmannNedwedetal., author = {Peter, Pascal and Hoffmann, Sebastian and Nedwed, Frank and Hoeltgen, Laurent and Weickert, Joachim}, title = {From Optimised Inpainting with Linear PDEs Towards Competitive Image Compression Codecs}, series = {Image and Video Technology, 7th Pacific-Rim Symposium, PSIVT 2015, Auckland, New Zealand, November 25-27, 2015}, booktitle = {Image and Video Technology, 7th Pacific-Rim Symposium, PSIVT 2015, Auckland, New Zealand, November 25-27, 2015}, publisher = {Springer}, address = {Cham}, isbn = {978-3-319-29450-6}, doi = {10.1007/978-3-319-29451-3_6}, pages = {63 -- 74}, abstract = {For inpainting with linear partial differential equations (PDEs) such as homogeneous or biharmonic diffusion, sophisticated data optimisation strategies have been found recently. These allow high-quality reconstructions from sparse known data. While they have been explicitly developed with compression in mind, they have not entered actual codecs so far: Storing these optimised data efficiently is a nontrivial task. Since this step is essential for any competetive codec, we propose two new compression frameworks for linear PDEs: Efficient storage of pixel locations obtained from an optimal control approach, and a stochastic strategy for a locally adaptive, tree-based grid. Suprisingly, our experiments show that homogeneous diffusion inpainting can surpass its often favoured biharmonic counterpart in compression. Last but not least, we demonstrate that our linear approach is able to beat both JPEG2000 and the nonlinear state-of-the-art in PDE-based image compression.}, language = {en} } @misc{PorajKobielskaPeterLeonhardtetal., author = {Poraj-Kobielska, Marzena and Peter, Sebastian and Leonhardt, Sabrina and Ullrich, Ren{\´e} and Scheibner, Katrin and Hofrichter, Martin}, title = {Immobilization of unspecific peroxygenases (EC 1.11.2.1) in PVA/PEG gel and hollow fiber modules}, series = {Biochemical Engineering Journal}, volume = {98}, journal = {Biochemical Engineering Journal}, issn = {1369-703X}, doi = {10.1016/j.bej.2015.02.037}, pages = {144 -- 150}, abstract = {The immobilization of enzymes has many advantages, such as higher stability, easier handling, and reuse of the catalyst. Here we report, for the first time, two effective methods for the immobilization of unspecific peroxygenase (UPO; EC 1.11.2.1). This biocatalyst type comprises heavily glycosylated heme-thiolate proteins that catalyze various biotechnologically relevant oxyfunctionalizations. Both the encapsulation in cryogel and the retention of the enzyme in hollow fiber modules were found to be efficient methods for their immobilization. After encapsulation, the enzyme still exhibited 60\% of its initial activity. Interestingly, we did not find differences in the kinetic parameters of free and immobilized UPOs. In long-term experiments, the conversion of the pharmaceutical diclofenac with immobilized UPOs in different reactor types yielded between 62 mg and 154 mg of the major human drug metabolite 4′-hydroxydiclofenac. The maximal total turnover number was about 60-fold higher compared to the free enzyme. A test over 5 months showed that storage of encapsulated UPOs in non-polar solvents (e.g., cyclohexane) helps to preserve the enzyme stability and increases their relative activity (by about ∼150\%, in the case of diclofenac hydroxylation). In addition to the hydrophilic substrate diclofenac, encapsulated UPOs also oxidized the hydrophobic model compound cyclohexane.}, language = {en} } @misc{DakshaDerzsiWilczeketal., author = {Daksha, Manaswi and Derzsi, Aranka and Wilczek, Sebastian and Trieschmann, Jan and Mussenbrock, Thomas and Awakowicz, Peter and Donk{\´o}, Zolt{\´a}n and Schulze, Julian}, title = {The Effect of Realistic Heavy Particle Induced Secondary Electron Emission Coefficients on the Electron Power Absorption Dynamics in Single- and Dual-Frequency CCPs}, series = {Plasma Sources Science and Technology}, volume = {26}, journal = {Plasma Sources Science and Technology}, number = {8}, issn = {1361-6595}, doi = {10.1088/1361-6595/aa7c88}, pages = {085006}, language = {en} } @misc{WilczekTrieschmannSchulzeetal., author = {Wilczek, Sebastian and Trieschmann, Jan and Schulze, Julian and Donko, Zoltan and Brinkmann, Ralf Peter and Mussenbrock, Thomas}, title = {Disparity between current and voltage driven capacitively coupled radio frequency discharges}, series = {Plasma Sources Science and Technology}, volume = {27}, journal = {Plasma Sources Science and Technology}, number = {12}, issn = {1361-6595}, doi = {10.1088/1361-6595/aae5c1}, pages = {12}, language = {en} } @misc{KlichWilczekJanssenetal., author = {Klich, Maximilian and Wilczek, Sebastian and Janssen, Jesper Frederikus Jacobus and Brinkmann, Ralf Peter and Mussenbrock, Thomas and Trieschmann, Jan}, title = {Ion dynamics in capacitively coupled argon-xenon discharges}, series = {Plasma Sources Science and Technology}, volume = {30}, journal = {Plasma Sources Science and Technology}, number = {6}, issn = {1361-6595}, doi = {10.1088/1361-6595/ac02b0}, language = {en} } @techreport{ThonickeRahnerArnethetal., author = {Thonicke, Kirsten and Rahner, Eva and Arneth, Almut and Bartkowski, Bartosz and Bonn, Aletta and D{\"o}hler, Christian and Finger, Robert and Freitag, Jens and Grosch, Rita and Grossart, Hans-Peter and Gr{\"u}tzmacher, Kim and Hartman Scholz, Amber and H{\"a}user, Christoph and Hickler, Thomas and H{\"o}lker, Franz and J{\"a}hnig, Sonja C. and Jeschke, Jonathan and Kassen, Rees and Kastner, Thomas and Kramer-Schadt, Stephanie and Krug, Cornelia and Lakner, Sebastian and Loft, Lasse and Matzdorf, Bettina and Meakins, Felicity and De Meester, Luc and Monaghan, Michael T. and M{\"u}ller, Daniel and Overmann, J{\"o}rg and Quaas, Martin and Radchuk, Viktoriia and Reyer, Christopher and Roos, Christian and Scholz, Imme and Schroer, Sibylle and Sioen, Giles Bruno and Sommer, Simone and Sommerwerk, Nike and Tockner, Klement and Turk, Zachary and Warner, Barbara and W{\"a}tzold, Frank and Wende, Wolfgang and Veenstra, Tonjes and Voort, Hein van de}, title = {10 Must-Knows aus der Biodiversit{\"a}tsforschung}, publisher = {Potsdam-Institut f{\"u}r Klimafolgenforschung e.V.

By contrast, the small-scale and heterogeneous occurrence of small-scale fog (hundreds of meters) particularly during summers is widely unconsidered. However, these events are important for the local vegetation and particularly for the biological soil crusts (BSC) that are widely distributed in this extreme ecosystem. Consequently, a case study in a typical fog oasis in the Pan de Az{\´u}car National Park was conducted to test the feasibility combining field measurements, drone profiling, remote sensing and numerical modeling (i) to investigate fog-type specific differences regarding dynamics, physical properties and formation, (ii) to test the applicability of remote sensing technology for fog monitoring based on existing low-resolution and a proposed new high-resolution product and (iii) to estimate the related fog water input to BSCs. Two types of fog were observed. The well-known fog/LST deck emerging from the Pacific Ocean with high water path and large spatial extent was the first type. Fog of the second type was patchier, small-scale and not necessarily connected to the LST over the ocean. Instead, fog formation of the second type was related to thermal breeze systems, which produced shallow clouds containing less water than those of type 1. In general, such small-scale fog events were not captured well by existing remote sensing products but could be detected with the proposed new high-resolution product which provided promising results. Both fog types were important water resources for the BSCs, with approximately 8\% to 24\% of the fog water flux available to the BSCs at the surface. The results indicated the feasibility of the proposed methods' pool to estimate the water budget of BSCs with a high spatial resolution in the future.}, language = {en} } @inproceedings{LangendoerferAdam, author = {Langend{\"o}rfer, Peter and Adam, Sebastian}, title = {A Graphical Tool for Specification, Rapid Prototyping and Implementation of Location Based Services}, language = {en} }
