This alumina body was formed by three classes of particles differing in size and shape: faceted particles typically ≤4 μm in diameter, platelets of average diameter 8 μm, 1.5 μm thickness, and small spheres 0.4 μm in diameter. The outstanding strength properties of the composite (600 MPa, ball-on-ring test) are a result of the high wetting capability of the glass phase on the Al2O3 surface.

Among these alloys, there are the conventional alloys, the so called casting alloys used without ceramics, the bonding alloys used with high fusing ceramics and the universal alloys used without or with low fusing ceramics. It is im portant to know the physical and mechanical properties of these materials but also their biocompatibility and their resistance to corrosion. Dental alloys are generally placed in the mouth for many years, they must not induce adverse biological reactions such as gingival swelling and erythema, mucosal pain and lichenoid reactions. Although these troubles are often caused not by the materials itself (1, 2), they can be induced by the metallic ions released during their corrosion. In order to decrease the risks to the health, it is necessary to study the corrosion of the dental alloys. Currently, the ISO 10271 Standard (3), describes 3 different corrosion tests: a static immersion test (chemical corrosion), an electrochemic al test and a tarnish test. However, there are no indications yet about the possible interpretation of test results. In this paper, we propose a method to compare and classify the dental alloys in relation to their chemical and electrochemical corrosion results. METHODS: The material tested are pure metals such as gold, palladium, silver, copper and zinc as well as dental alloys which are commercially sold (see Table 1). 54 different materials have been tested. A minimum of four samples of each material were tested by electrochemic al corrosio n and a minimum of three in chemical test. The samples were cast and prepared as indicated by the manufacturer and by the ISO 10271. For the electrochemical test, the samples are in the form of disks 11 mm in diameter. They are tested with a potentiostat/galvanostat Voltalab Model 21. For the chemical test, the samples are rectangular with the dimensions 35X10X1.7 mm. The solution used and the operating conditions are described in the ISO 10271.

We created a novel drug-eluting stent system that includes several new features in the rapidly evolving field of stent-based drug delivery. Methods and Results The aim of the present study was the preclinical evaluation of a stent-coating system permitting individual, on-site coating of stents with a unique microporous surface allowing for individualizable, dose-adjustable, and multiple coatings with identical or various compounds, designated ISAR (individualizable drug-eluting stent system to abrogate restenosis). Stents were coated with 0.75\% rapamycin solution, and high-performance liquid chromatography (HPLC)-based determination of drug release profile indicated drug release for >21 days. Rapamycin-eluting microporous (REMP) stents implanted in porcine coronary arteries were safe. To determine the efficacy of REMP stents, this novel drug-eluting stent platform was compared with the standard sirolimus-eluting stent. At 30 days, in-stent neointima formation in porcine coronary arteries was similar in both groups, yielding a significant decrease of neointimal area and injury-dependent neointimal thickness compared with bare-metal stents. Conclusion The ISAR drug-eluting stent platform as a novel concept for stent coating allows for a safe, effective, on-site stent coating process, thus justifying further clinical evaluation to decrease in-stent restenosis in humans. In-stent neointima formation can be successfully attenuated by drug-eluting stents. We introduce a novel conceptual approach for stent-coating that allows for dose-adjustable, on-site stent coating process if desired with multiple compounds.

Along with the success shown, current DES also present limitations related to the presence of polymer-coating, fixed drug, and dose used. With the ISAR (Individualized Drug-Eluting Stent System to Abrogate Restenosis) project, a DES system has been developed that permits individualized choice of the drug and dose to use for the given patient. The objective of this prospective dose finding study was to assess the feasibility, safety, and efficacy of a polymer-free on-site stent coating with increasing rapamycin doses. Methods and results In this dose finding study, 602 patients were sequentially enrolled in four groups: microporous bare metal stent (BMS), DES stents coated with a 0.5, 1.0, and 2.0\% rapamycin solution. The angiographic in-segment restenosis rate at follow-up angiography was the primary study endpoint. In-segment restenosis was significantly reduced from 25.9\% with BMS to 18.9, 17.2, and 14.7\% with 0.5, 1.0, and 2.0\% rapamycin-eluting stents, respectively (P=0.024). Similarly, the need for target lesion revascularization at 1 year follow-up was reduced from 21.5\% with BMS to 16.4, 12.6, and 8.8\% with 0.5, 1.0, and 2.0\% rapamycin-eluting stents, respectively (P=0.006). Conclusion The placement of polymer-free stents coated on-site with rapamycin is feasible and safe. Furthermore, a dose-dependent efficacy in restenosis prevention is achievable with this new DES concept.}, language = {en} } @incollection{Weber, author = {Weber, Karsten}, title = {Der Preis der Informationsfreiheit}, series = {Wissen und Bildung in der modernen Gesellschaft}, booktitle = {Wissen und Bildung in der modernen Gesellschaft}, publisher = {Rosa-Luxemburg-Stiftung e.V.}, address = {Leipzig}, language = {de} } @inproceedings{MeyerSickendiekHusseinBaumann, author = {Meyer-Sickendiek, Burkhard and Hussein, Hussein and Baumann, Timo}, title = {Recognizing Modern Sound Poetry with LSTM Networks}, series = {Proceedings of Elektronische Sprachsignalverarbeitung (ESSV)}, booktitle = {Proceedings of Elektronische Sprachsignalverarbeitung (ESSV)}, editor = {Berton, Andr{\´e} and Haiber, Udo and Minker, Wolfgang}, publisher = {TUDpress}, address = {Ulm, Germany}, isbn = {978-3-959081-28-3}, pages = {192 -- 199}, abstract = {Our paper focuses on the computational analysis of "readout poetry" (german: H{\"o}rdichtung) - recordings of poets reading their own work - with regards to the most important type of this genre, the modern "sound poetry" (german: Lautdichtung). Whereas "readout poetry" often uses normal words and sentences, the "sound poetry", developed by dadaistic poets like Hugo Ball and Kurt Schwitters or concrete poets like Ernst Jandl, Oskar Pastior, or Bob Cobbing, combines the "microparticles of the human voice" like the segments in Ernst Jandls sound poem "schtzngrmm" ("schtzngrmm / schtzngrmm / tttt / tttt / grrrmmmmm / tttt / sch / tzngrmm"). Within the genre of sound poetry, there are two main forms: The lettristic and the syllabic decomposition. A short anecdote will explain this difference: The dadaist Raoul Hausmann developed the lettristic sound poetry in his early dadaistic poem "fmsbw" from 1918. This is said to have inspired his successor Schwitters, whose famous "Ursonate" [The Sonata in Primal Speech] begins with the words "F{\"u}mms b{\"o} w{\"o} t{\"a}{\"a} z{\"a}{\"a} Uu". With the "Ursonate", Schwitters developed a syllabic variation of the lettristic poems of Hausmann. The paper shows how to train a bidirectional LSTM network in order to differ between these "dadaistic" sound poems and the "normal" read out poems. In a further step, we will also show how to distinguish between the lettristic and the syllabic decomposition. Based on a bidirectional LSTM network that reads encodings of the character sequence in the poem and uses the output of each directional layer, we identify poems of the sound poetry genre and differentiate between its two types of compositions. The classification results of sound poetry vs. other poetry as well as lettristic vs. syllabic decomposition are with a high performance, yielding a f-scores of 0.86 and 0.84, respectively.}, subject = {Sprachverarbeitung}, language = {en} } @inproceedings{LaumerSchmidtStichel, author = {Laumer, Tobias and Schmidt, Michael and Stichel, Thomas}, title = {Correlation Analysis of Different Building Parameters on the Part Properties of Parts Built by Simultaneous Laser Beam Melting of Polymers}, series = {Fraunhofer Direct Digital Manufacturing Conference DDMC 2016 : Conference Proceedings, March 2016, Berlin}, booktitle = {Fraunhofer Direct Digital Manufacturing Conference DDMC 2016 : Conference Proceedings, March 2016, Berlin}, publisher = {Fraunhofer Verlag}, abstract = {Simultaneous Laser Beam Melting of polymers (SLBM) allows the generation of multi-material components,consisting of different thermoplastic polymers, within one additive building process. Besides the common advantagesof conventional Laser Beam Melting (LBM), multi-material components built by SLBM can fulfill different productrequirements like different chemical resistances or haptic material properties within a single part. To achieve suchparts, different powder materials are deposited next to each other and preheated a few degrees below their meltingtemperatures by infrared emitters and laser radiation (λ = 10.60 μm), before in the last step the preheated powdersare molten simultaneously by an additional laser source (λ = 1.94 μm). In this paper, different polymer powders likepolypropylene (PP) and polyamide 12 (PA12) are used for the generation of multi-material specimens. By varyingdifferent building parameters according to a specified design of experiments, their influence on the part properties isanalyzed. Important building parameters are the intensity and the irradiation time of the laser beam used for meltingthe preheated powders.

With a measurement setup using two integration spheres, it was shown that the optical material properties of polymer powders differ significantly due to multiple reflections within the powder compared to solid bodies of the same material. Additionally, the absorption behavior of the single particles shows an important influence on the overall optical material properties, especially the reflectance of the powder bed. Now the setup is modified to allow measurements at higher temperatures. Because crystalline areas of semi-crystalline thermoplastics are mainly responsible for the absorption of the laser radiation, the influence of the temperature increase on the overall optical material properties is analyzed. As material, conventional polyamide 12 and polypropylene as new polymer powder material, is used.

The investigations point out that pore density is a superior indicator than porosity for mechanical issues.

The article focusses on the importance of time for the political adult education. Current socio-cultural and socio-economic challenges - in particular: the commodification and acceleration in the context of education and learning - results in a wide range of pressing time issues. However the adult education und the political education pay little attention to the importance of time. For this reason, this issue will be deepened in the article. First, the situation of the political adult education and secondly, the state of research are examined. On the base of the findings, three approaches are pointed out, which emphasize the importance of time for the political adult education: political education as a process and as a deceleration and also as a subject to understand and judge the temporality of politics and society as a necessary condition to participate in shaping the time structures.

In particular, windgas in the heat market is discussed in the utilization cascade of wind energy. The new "power-to-gas" concept opens up completely new possibilities for the integration of renewable energies and for coupling the electricity and gas grids. The Sabatier process, which has been known for 100 years, was first developed for this purpose in 2008 under the leadership of the Center for Solar Energy and Hydrogen Research and Fraunhofer IWES (formerly ISET) with electrolysis to create the "power-to-gas" concept for energy storage. A first pilot plant was built by ZSW Stuttgart on behalf of SolarFuel in 2009. This plant proves the technical feasibility of the new technology. Renewable gas is stored, transported and used as required as control and reserve energy via reconversion, e.g. in combined cycle power plants. In this way, decentrally generated renewable electricity is converted into a CO2 -neutral energy carrier with high energy density. The key advantage of renewable methane is the use of existing infrastructure such as gas grids, gas storage and end-use equipment for the integration of renewable energy. Technologies for natural gas are state of the art and commercially available. Methane also has three times the energy density of hydrogen.}, language = {en} } @incollection{Haug, author = {Haug, Sonja}, title = {Migration aus Mittel- und Osteuropa nach Deutschland}, series = {Migration in Europa}, booktitle = {Migration in Europa}, editor = {Haug, Sonja and Swiaczny, Frank}, organization = {Bundesinstitut f{\"u}r Bev{\"o}lkerungsforschung}, pages = {133 -- 151}, abstract = {Im Zuge der EU-Ost-Erweiterung sind im Mai 2004 zehn L{\"a}nder der EU beigetreten.

Among the participating projects, the one presented herein focuses on the development of a smart expansion joint, to assess the traffic parameters on site. This is achieved by measuring velocity and weight of crossing vehicles. In reference measurements, performed with a three-axle truck and a typical tractor semi-trailer combination with five axles in total, it was shown that the interaction between the vehicle and the expansion joint is highly dynamic and depends on several factors. To get more insight into this dynamic problem, a virtual test rig was set up. Although nearly all vehicle parameters had to be estimated, the simulation results conform very well with the measurements and are robust to vehicle parameter variations. In addition, they indicate a significant influence of the expansion joint dynamic to the peak values of the measured wheel loads, in particular on higher driving velocities. By compensating the relevant dynamic effects in the measurements, a "smart" data processing algorithm makes it possible to determine the actual vehicle weights in random traffic with reliability and appropriate accuracy.}, language = {en} } @incollection{FinckhNiedermeierSchmittetal., author = {Finckh, Wolfgang and Niedermeier, Roland and Schmitt, Alexander and Zilch, Konrad}, title = {Beispiel 3: Verst{\"a}rkung eines Plattenbalkens mit aufgeklebten CFK-Lamellen}, series = {Erl{\"a}uterungen und Beispiele zur DAfStb-Richtlinie "Verst{\"a}rken von Betonbauteilen mit geklebter Bewehrung"}, booktitle = {Erl{\"a}uterungen und Beispiele zur DAfStb-Richtlinie "Verst{\"a}rken von Betonbauteilen mit geklebter Bewehrung"}, editor = {Zilch, Konrad}, publisher = {Beuth}, address = {Berlin}, isbn = {978-3-410-65245-8}, issn = {0171-7197}, pages = {83 -- 108}, subject = {Betonbauteil}, language = {de} } @article{LinnerSeelingerVogtLydiaetal., author = {Linner, Thomas and Seelinger, Anja and Vogt Lydia, and Sch{\"a}pers Barbara, and Steinb{\"o}ck, Martina and Krewer, Carmen and Bock, Thomas}, title = {REACH: Solutions for Technology-Based Prevention and Empowerment for Older People and their Caregivers}, series = {Journal of Population Ageing: Special Issue on responsive engagement of older persons promoting activity and customized healthcare}, volume = {13}, journal = {Journal of Population Ageing: Special Issue on responsive engagement of older persons promoting activity and customized healthcare}, number = {1}, publisher = {Springer Nature}, doi = {10.1007/s12062-020-09268-5}, pages = {131 -- 137}, abstract = {REACH stands for "Responsive Engagement of the Elderly Promoting Activity and Customized Healthcare".

With increasing complexity of industrial products, also BOMs become more complex and thus prone to errors, for example when the individual parts of a product are changed during the product development process. Frequently, these Bill of Materials errors have to be identified manually or by using simple, rule-based schemes. In this paper, we provide a technical background of BOMs, showing the intricacy of temporal BOMs errors in an industrial product development process. The work of other authors, which focused on association mining and tree reconciliation to detect Bill of Materials errors, is analysed. We found that there is currently no system being able to prescribe where in a Bill of Materials and when in the product development process, errors are probable to occur. Also, Machine Learning (ML) methods have not been applied yet. Based on these findings, we formalize the notions Bill of Materials and Bill of Materials errors. Furthermore, we present a deterministic distance measure for BOMS. We provide an answer to the main question of how to represent a Bill of Materials for Machine Learning tasks by solving the orthogonal Procrustes problem for dynamic, hierarchical datasets. Then, we describe an isolation forest based approach to temporal anomaly detection, which points at potential errors in a Bill of Materials at a specific timestamp. Furthermore, we apply Machine Learning and present a multi-output Multi Layer Perceptron for the prediction of temporal Bill of Materials errors. The model predicts where and at which point of time Bill of Materials errors are probable to occur, which renders it a prescriptive system. Eventually, we optimize the performance of our model using contextualization via -means clustering. Finally, we apply our prescriptive pipeline to a real world dataset and show its superiority to existing methods using a qualitative comparison.}, language = {en} } @article{SchwabPogrebnojFreundetal., author = {Schwab, E. and Pogrebnoj, S. and Freund, M. and Flossmann, F. and Vogl, Stefanie and Frommolt, K.-H.}, title = {Automated bat call classification using deep convolutional neural networks}, series = {Bioacoustics}, journal = {Bioacoustics}, publisher = {Taylor \& Francis}, doi = {10.1080/09524622.2022.2050816}, pages = {1 -- 16}, abstract = {Identification of bats is most practically done by exploiting the characteristic features of their echolocation calls.

We have carried out SPA-LEED experiments to measure the barriers of the processes: we prepare an initial predominantly 5-step island height distribution and we deposit an additional 0.5ML Pb at different growth temperatures Tg to determine the transition to the next preferred height of 7-step islands (i.e. 2-step islands on top of the 5-step islands) with Spot Profile Analysis(SPA-LEED).

Photo-excitation of bulk and layered semiconductors was achieved with 800-nm wavelength femtosecond laser pulses. Optical excitation triggers a chain of relaxation processes, causing rapid lattice heating, generation and propagation of stress/strain waves into the bulk and eventual anharmonic decay of coherent acoustic phonons into the thermal bath of the solid. While the first steps of carrier relaxation, excitation and decay of Raman-active optical phonons have been in the past characterized optically at surfaces, the bulk acoustic dynamics at longer times has not. We measure length scales of lattice excitation, thereby detecting ultrafast heat diffusion via fast electrons, coherent acoustic pulse propagation into the bulk or across buried interfaces and anharmonic damping of non-equilibrium acoustic phonons.

Six strain gages per specimen allowed to observe the evolution of the strain with the bending moment during the tests. All bending specimens were bent until a total compressive deformation of 2.5 \%. It was observed that the corresponding tensile strain was significant lower and slightly different for each specimen type. In addition, a characteristic non-uniform distribution of deformation twinning was observed. The induced residual stresses after bending were characterized by X-ray diffraction (XRD) and incremental hole-drilling (IHD). Due to the different mechanical behavior in tension and compression, an asymmetric residual stress distribution after bending could be observed.

Relying on a sample of 304 projects conducted at various industry sectors and companies, results show that IS offshoring primarily occurs in sectors Telecommunications and IT at large corporations. Cost reduction is the main reason for going offshore and offshore projects are executed as part of a larger program at companies. Noticeably, most projects are delivered from India. Additionally, neither captive offshoring nor offshore outsourcing dominates as a de-livery option. Comparing different project subgroups regarding project success, the results reveal that projects delivered by an internal or partially owned service provider are more successful. Other project characteristics such as a project's embedded-ness in a larger offshoring program, a project's size, or a project's offshoring degree in terms of relatively offshored labor hours show few significant differences.
