It is shown that whenever U : Ω × (0,∞) → ℝn is a bounded and sufficiently regular solenoidal vector field any non-trivial global bounded solution of (⋆) approaches the trivial equilibrium at a rate that, with respect to the norm in either of the spaces L1(Ω) and L∞(Ω), can be controlled from above and below by appropriate multiples of 1/(t + 1). This underlines that, even up to this quantitative level of accuracy, the large time behaviour in (⋆) is essentially independent not only of the particular fluid flow, but also of any effect originating from chemotactic cross-diffusion. The latter is in contrast to the corresponding Cauchy problem, for which known results show that in the n = 2 case the presence of chemotaxis can significantly enhance biomixing by reducing the respective spatial L1 norms of solutions.}}, author = {{Cao, Xinru and Winkler, Michael}}, issn = {{0308-2105}}, journal = {{Proceedings of the Royal Society of Edinburgh: Section A Mathematics}}, number = {{5}}, pages = {{939--955}}, publisher = {{Cambridge University Press (CUP)}}, title = {{{Sharp decay estimates in a bioconvection model with quadratic degradation in bounded domains}}}, doi = {{10.1017/s0308210518000057}}, volume = {{148}}, year = {{2018}}, } @article{63368, author = {{Winkler, Michael}}, issn = {{0167-8019}}, journal = {{Acta Applicandae Mathematicae}}, number = {{1}}, pages = {{1--17}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Boundedness in a Chemotaxis-May-Nowak Model for Virus Dynamics with Mildly Saturated Chemotactic Sensitivity}}}, doi = {{10.1007/s10440-018-0211-0}}, volume = {{163}}, year = {{2018}}, } @article{63370, author = {{Espejo, Elio and Winkler, Michael}}, issn = {{0951-7715}}, journal = {{Nonlinearity}}, number = {{4}}, pages = {{1227--1259}}, publisher = {{IOP Publishing}}, title = {{{Global classical solvability and stabilization in a two-dimensional chemotaxis-Navier–Stokes system modeling coral fertilization}}}, doi = {{10.1088/1361-6544/aa9d5f}}, volume = {{31}}, year = {{2018}}, } @article{63377, author = {{Winkler, Michael}}, issn = {{0044-2275}}, journal = {{Zeitschrift für angewandte Mathematik und Physik}}, number = {{2}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Finite-time blow-up in low-dimensional Keller–Segel systems with logistic-type superlinear degradation}}}, doi = {{10.1007/s00033-018-0935-8}}, volume = {{69}}, year = {{2018}}, } @article{63375, author = {{Winkler, Michael}}, issn = {{1422-6928}}, journal = {{Journal of Mathematical Fluid Mechanics}}, number = {{4}}, pages = {{1889--1909}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Does Fluid Interaction Affect Regularity in the Three-Dimensional Keller–Segel System with Saturated Sensitivity?}}}, doi = {{10.1007/s00021-018-0395-0}}, volume = {{20}}, year = {{2018}}, } @article{63381, author = {{Winkler, Michael}}, issn = {{1424-3199}}, journal = {{Journal of Evolution Equations}}, number = {{3}}, pages = {{1267--1289}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Global mass-preserving solutions in a two-dimensional chemotaxis-Stokes system with rotational flux components}}}, doi = {{10.1007/s00028-018-0440-8}}, volume = {{18}}, year = {{2018}}, } @article{63380, author = {{Winkler, Michael}}, issn = {{0022-0396}}, journal = {{Journal of Differential Equations}}, number = {{10}}, pages = {{6109--6151}}, publisher = {{Elsevier BV}}, title = {{{Global existence and stabilization in a degenerate chemotaxis-Stokes system with mildly strong diffusion enhancement}}}, doi = {{10.1016/j.jde.2018.01.027}}, volume = {{264}}, year = {{2018}}, } @article{63376, author = {{Winkler, Michael}}, issn = {{0951-7715}}, journal = {{Nonlinearity}}, number = {{5}}, pages = {{2031--2056}}, publisher = {{IOP Publishing}}, title = {{{A critical blow-up exponent in a chemotaxis system with nonlinear signal production}}}, doi = {{10.1088/1361-6544/aaaa0e}}, volume = {{31}}, year = {{2018}}, } @article{63382, author = {{Winkler, Michael and Yokota, Tomomi}}, issn = {{0362-546X}}, journal = {{Nonlinear Analysis}}, pages = {{123--141}}, publisher = {{Elsevier BV}}, title = {{{Stabilization in the logarithmic Keller–Segel system}}}, doi = {{10.1016/j.na.2018.01.002}}, volume = {{170}}, year = {{2018}}, } @inbook{46565, author = {{Georgi, Christopher}}, booktitle = {{Sprachliche Gewalt.

Good sampling rate converters in the time domain have been known, for instance, in terms of time-varying 'Sinc' or fixed 'Farrow' polynomial filters. The former can deliver nearly exact conversion at high complexity, while the latter has pronounced computational efficiency with limited accuracy. Only recently, it was shown that a composite 'polyphase Farrow' form with high resampling precision can be implemented with quasi-fixed filters that operate at the input sampling rate. We therefore propose to capitalize from that fixed-filter architecture in that we translate the polyphase-Farrow filters into an equivalent FFT-based overlap-save form. Experimental evaluation and comparison with other state-of-the art frequency-domain approaches then proves currently the best price-performance ratio of the proposed algorithm. It is thus an ideal candidate for the new framework of acoustic sensor networks that critically rests upon fast and accurate alignment of autonomous sampling processes.}}, author = {{Schmalenstroeer, Joerg and Chinaev, Aleksej and Enzner, Gerald}}, booktitle = {{Speech Communication; 13th ITG-Symposium}}, issn = {{null}}, pages = {{1--5}}, title = {{{Fast and Accurate Audio Resampling for Acoustic Sensor Networks by Polyphase-Farrow Filters with FFT Realization}}}, year = {{2018}}, } @inproceedings{56582, author = {{Usbeck, Ricardo and Gusmita, Ria Hari and Ngonga Ngomo, Axel-Cyrille and Saleem, M}}, booktitle = {{Joint proceedings of the 4th Workshop on Semantic Deep Learning (SemDeep-4) and NLIWoD4: Natural Language Interfaces for the Web of Data {(NLIWOD-4)} and 9th Question Answering over Linked Data challenge {(QALD-9)} co-located with 17th International Semantic Web Conference {(ISWC} 2018), Monterey, California, United States of America, October 8th - 9th, 2018.}}, keywords = {{2018 dice diesel group_aksw limbo limboproject ngonga qamel simba solide usbeck}}, pages = {{58–64}}, title = {{{9th Challenge on Question Answering over Linked Data (QALD-9) (invited paper)}}}, year = {{2018}}, } @inproceedings{57288, author = {{Speck, René and Röder, Michael and Conrads, Felix and Rebba, Hyndavi and Romiyo, Catherine Camilla and Salakki, Gurudevi and Suryawanshi, Rutuja and Ahmed, Danish and Srivastava, Nikit and Mahajan, Mohit and Ngonga Ngomo, Axel-Cyrille}}, booktitle = {{Semantic Web Evaluation Challenge}}, keywords = {{2018 ahmed conrads dice fox group_aksw mahajan ngonga projecthobbit rebba roeder romiyo salakki simba speck srivastava suryawanshi}}, pages = {{39–51}}, publisher = {{Springer International Publishing}}, title = {{{Open Knowledge Extraction Challenge 2018}}}, year = {{2018}}, } @article{56858, author = {{Bergmann, Claudia Dorit}}, journal = {{Historia Religionum }}, pages = {{91--103}}, title = {{{Choices in Ritual Imagination: The Role of the Messianic Figure in Early Jewish and Christian Texts about the Meal in the World to Come}}}, volume = {{10}}, year = {{2018}}, } @article{56857, author = {{Bergmann, Claudia Dorit and Jörg, Rüpke}}, journal = {{Historia Religionum }}, pages = {{11--12}}, title = {{{Looking Back at the Dynamics of Jewish Ritual Practices in Pluralistic Contexts.
