Typically, bulky pulse compressors consisting of gratings or prisms are used to address this issue by precompensating the dispersion of the optical components. However, these devices are only able to compensate for a part of the dispersion (second-order dispersion). Here, we present a compact pulse-shaping device that uses plasmonic metasurfaces to apply an arbitrarily designed spectral phase delay allowing for a full dispersion control. Furthermore, with specific phase encodings, this device can be used to temporally reshape the incident laser pulses into more complex pulse forms such as a double pulse. We verify the performance of our device by using an SHG-FROG measurement setup together with a retrieval algorithm to extract the dispersion that our device applies to an incident laser pulse.}}, author = {{Geromel, René and Georgi, Philip and Protte, Maximilian and Lei, Shiwei and Bartley, Tim and Huang, Lingling and Zentgraf, Thomas}}, issn = {{1530-6984}}, journal = {{Nano Letters}}, keywords = {{Mechanical Engineering, Condensed Matter Physics, General Materials Science, General Chemistry, Bioengineering}}, number = {{8}}, pages = {{3196 -- 3201}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Compact Metasurface-Based Optical Pulse-Shaping Device}}}, doi = {{10.1021/acs.nanolett.2c04980}}, volume = {{23}}, year = {{2023}}, } @article{44837, abstract = {{Hydrothermal carbonization (HTC) is an efficient thermochemical method for the conversion of organic feedstock to carbonaceous solids. HTC of different saccharides is known to produce microspheres (MS) with mostly Gaussian size distribution, which are utilized as functional materials in various applications, both as pristine MS and as a precursor for hard carbon MS. Although the average size of the MS can be influenced by adjusting the process parameters, there is no reliable mechanism to affect their size distribution. Our results demonstrate that HTC of trehalose, in contrast to other saccharides, results in a distinctly bimodal sphere diameter distribution consisting of small spheres with diameters of (2.1 ± 0.2) μm and of large spheres with diameters of (10.4 ± 2.6) μm. Remarkably, after pyrolytic post-carbonization at 1000 °C the MS develop a multimodal pore size distribution with abundant macropores > 100 nm, mesopores > 10 nm and micropores < 2 nm, which were examined by small-angle X-ray scattering and visualized by charge-compensated helium ion microscopy. The bimodal size distribution and hierarchical porosity provide an extraordinary set of properties and potential variables for the tailored synthesis of hierarchical porous carbons, making trehalose-derived hard carbon MS a highly promising material for applications in catalysis, filtration, and energy storage devices.}}, author = {{Wortmann, Martin and Keil, Waldemar and Diestelhorst, Elise and Westphal, Michael and Haverkamp, René and Brockhagen, Bennet and Biedinger, Jan and Bondzio, Laila and Weinberger, Christian and Baier, Dominik and Tiemann, Michael and Hütten, Andreas and Hellweg, Thomas and Reiss, Günter and Schmidt, Claudia and Sattler, Klaus and Frese, Natalie}}, issn = {{2046-2069}}, journal = {{RSC Advances}}, keywords = {{General Chemical Engineering, General Chemistry}}, number = {{21}}, pages = {{14181--14189}}, publisher = {{Royal Society of Chemistry (RSC)}}, title = {{{Hard carbon microspheres with bimodal size distribution and hierarchical porosity via hydrothermal carbonization of trehalose}}}, doi = {{10.1039/d3ra01301d}}, volume = {{13}}, year = {{2023}}, } @misc{42999, author = {{Bünder, Dirk and Neukötter, Moritz}}, title = {{{Theoretische Beschreibung des Polymerverhaltens in Polymerlösungen und - schmelzen: Simulationen anhand des Rolie-Poly-Modells}}}, year = {{2023}}, } @misc{42995, author = {{Al Mamoun, Mohamed and Neukötter, Moritz}}, title = {{{Evaluation of self-built low-budget particle sensors (Study Project)}}}, year = {{2023}}, } @book{44246, author = {{Teichert, Jeannine}}, publisher = {{Springer VS}}, title = {{{Digital occupants – Wie digitale Medien die kommunikative Aushandlung von Freundschaften verändern}}}, year = {{2023}}, } @article{44247, author = {{Teichert, Jeannine and Meister, Dorothee M.}}, journal = {{MedienPädagogik}}, title = {{{Mediale Identitätsaushandlungen deutscher MigrantInnen im Zuge des Brexit}}}, year = {{2023}}, } @inbook{42183, author = {{Kruse, Iris and Maubach, Bernd and Tönsing, Johanna}}, booktitle = {{Salah Naoura}}, editor = {{Kruse, Iris and Josting, Petra}}, isbn = {{978-3-96848-094-7}}, pages = {{249--262}}, publisher = {{kopaed}}, title = {{{"Lesungen vor Kindern sind für mich Theater" / Salah Naouras Sicht auf Wirkliches und Mögliches in Autor*innenlesungen für Kinder in der Schule}}}, volume = {{12}}, year = {{2023}}, } @inbook{42182, author = {{Kruse, Iris and Schäfer, Luisa Maria}}, booktitle = {{Salah Naoura}}, editor = {{Kruse, Iris and Josting, Petra}}, isbn = {{978-3-96848-094-7}}, pages = {{235--248}}, publisher = {{kopaed}}, title = {{{Held*innenträume.

Here, we study the genome median problem, a related computational problem which, given a set of three or more genomes, asks to find a new genome that minimizes the sum of pairwise distances between it and the given genomes. The distance stands for the amount of evolution observed at the genome level, for which we determine the minimum number of rearrangement operations necessary to transform one genome into the other. For almost all rearrangement operations the median problem is NP-hard, with the exception of the breakpoint median that can be constructed efficiently for multichromosomal circular and mixed genomes. In this work, we study the median problem under a restricted rearrangement measure called c4-distance, which is closely related to the breakpoint and the DCJ distance. We identify tight bounds and decomposers of the c4-median and develop algorithms for its construction, one exact ILP-based and three combinatorial heuristics. Subsequently, we perform experiments on simulated data sets. Our results suggest that the c4-distance is useful for the study the genome median problem, from theoretical and practical perspectives.}}, author = {{Silva, Helmuth O.M. and Rubert, Diego P. and Araujo, Eloi and Steffen, Eckhard and Doerr, Daniel and Martinez, Fábio V.}}, issn = {{0399-0559}}, journal = {{RAIRO - Operations Research}}, keywords = {{Management Science and Operations Research, Computer Science Applications, Theoretical Computer Science}}, number = {{3}}, pages = {{1045--1058}}, publisher = {{EDP Sciences}}, title = {{{Algorithms for the genome median under a restricted measure of rearrangement}}}, doi = {{10.1051/ro/2023052}}, volume = {{57}}, year = {{2023}}, } @unpublished{44859, author = {{Ma, Yulai and Mattiolo, Davide and Steffen, Eckhard and Wolf, Isaak Hieronymus}}, booktitle = {{arXiv:2305.08619}}, title = {{{Sets of r-graphs that color all r-graphs}}}, year = {{2023}}, } @article{44888, author = {{Lenz, Peter and Mahnken, Rolf}}, issn = {{1617-7061}}, journal = {{PAMM}}, keywords = {{Electrical and Electronic Engineering, Atomic and Molecular Physics, and Optics}}, number = {{1}}, publisher = {{Wiley}}, title = {{{Thermo‐chemo‐mechanical modelling of a curing process combined with mean‐field homogenization methods at large strains}}}, doi = {{10.1002/pamm.202200214}}, volume = {{22}}, year = {{2023}}, } @inproceedings{34294, author = {{Wolters, Dennis and Engels, Gregor}}, booktitle = {{MODELSWARD'23}}, isbn = {{978-989-758-633-0}}, issn = {{2184-4348}}, pages = {{133--142}}, publisher = {{SCITEPRESS}}, title = {{{Model-driven Collaborative Design of Professional Education Programmes With Extended Online Whiteboards}}}, doi = {{10.5220/0011675700003402}}, year = {{2023}}, } @unpublished{44887, author = {{Cheng, Chun and Song, Chunlei and Mahnken, Rolf and Yuan, Zhipeng and Yu, Liang and Ju, Xiaozhe}}, publisher = {{Elsevier BV}}, title = {{{A Non-Linear Mean-Field Debonding Model at Large Strains for the Analysis of Fibre Kinking in Ud Composites}}}, year = {{2023}}, } @article{44891, author = {{Westermann, Hendrik and Mahnken, Rolf}}, issn = {{1617-7061}}, journal = {{PAMM}}, keywords = {{Electrical and Electronic Engineering, Atomic and Molecular Physics, and Optics}}, number = {{1}}, publisher = {{Wiley}}, title = {{{A thermodynamic framework for the phase‐field approach considering carbide precipitation during phase transformations}}}, doi = {{10.1002/pamm.202200080}}, volume = {{22}}, year = {{2023}}, } @article{44892, author = {{Hamdoun, Ayoub and Mahnken, Rolf}}, issn = {{1617-7061}}, journal = {{PAMM}}, keywords = {{Electrical and Electronic Engineering, Atomic and Molecular Physics, and Optics}}, number = {{1}}, publisher = {{Wiley}}, title = {{{A finite strain gradient theory for viscoplasticity by means of micromorphic regularization}}}, doi = {{10.1002/pamm.202200074}}, volume = {{22}}, year = {{2023}}, } @article{44897, author = {{Kaimann, Daniel and Spiess Bru, Clarissa Laura Maria and Frick, Bernd}}, journal = {{Journal of Wine Economics}}, title = {{{Ratings Meet Prices: The Dynamic Relationship of Quality Signals}}}, year = {{2023}}, } @inproceedings{44502, abstract = {{In order to follow the 1.5 degree path of the Paris Climate Agreement, drastic greenhouse gas reduction measures are needed in the transport sector. The potential of public transport and new mobility services to reduce transport-related greenhouse gas emissions cannot yet be fully exploited, especially in rural regions. This paper presents the concept of an innovative mobility system, called NeMo.bil, that intends to fill the gap between individual and public transport to create a demand-oriented and sustainable mobility offer. The concept is based on convoy formation of autonomously driving lightweight vehicles serving the first and last mile and a larger towing vehicle carrying enough power and energy to move the convoy over longer distances at higher speeds. This combination of two different vehicles, intelligently controlled by a digital ecosystem, aims to significantly increasing energy, resource and cost efficiency. Based on an analysis of previous approaches for innovative mobility solutions, the concept is derived from a technical and sociological perspective and its potential for reducing energy demand is calculated.}}, author = {{Ostermann, Moritz and Behm, Jonathan and Marten, Thorsten and Tröster, Thomas and Weyer, Johannes and Cepera, Kay and Adelt, Fabian}}, booktitle = {{Towards the New Normal in Mobility}}, editor = {{Proff, Heike}}, isbn = {{9783658394370}}, location = {{Duisburg}}, publisher = {{Springer Fachmedien Wiesbaden}}, title = {{{Individualization of Public Transport – Integration of Technical and Social Dimensions of Sustainable Mobility}}}, doi = {{10.1007/978-3-658-39438-7_25}}, year = {{2023}}, }
