In this article the test response is compacted by several multiple input shift registers without feedback (NF-MISR). The shift registers are running on a k-times higher clock frequency than the test clock. For each test clock cycle only one out of the k outputs of each shift register is evaluated by the ATE. The impact of consecutive X values within the scan chains is reduced by a periodic permutation of the NF-MISR inputs. As a result, no additional external control signals or test set dependent control logic is required. The benefits of the proposed method are shown by the example of an implementation on a Verigy ATE. Experiments on three industrial circuits demonstrate the effectiveness of the proposed approach in comparison to a commercial DFT solution.}, language = {en} } @book{StillmarkLimbergGoetzmannetal.2020, author = {Stillmark, Hans-Christian and Limberg, J{\"o}rg and G{\"o}tzmann, Jutta and Vogt, Jochen and Eke, Norbert Otto and Braun, Matthias and Clare, Jennifer and Grimm, Christa and Hofmann, Michael and Bauer, Gerhard and Starke, Frank}, title = {Peter Weiss erinnernd - Ansichten und Einsichten}, editor = {Stillmark, Hans-Christian}, edition = {150}, publisher = {Weidler Buchverlag}, address = {Berlin}, isbn = {978-3-89693-747-6}, publisher = {Universit{\"a}t Potsdam}, pages = {157}, year = {2020}, abstract = {Der Band versammelt verschiedenen Beitr{\"a}ge, die sich mit dem Leben und Werk von Peter Weiss auseinandersetzen.

To meet this challenge, a cellular surveillance mechanism, termed the spindle assembly checkpoint (SAC), evolved that monitors the correct attachment of chromosomes and blocks progression through mitosis if corrections are needed. While the central role of the SAC for genome integrity is well established, its functional dissection has been hampered by the limited availability of appropriate small molecule inhibitors. Using a fluorescence polarization-based screen, we identify Mad2 inhibitor-1 (M2I-1), the first small molecule inhibitor targeting the binding of Mad2 to Cdc20, an essential protein-protein interaction (PPI) within the SAC. Based on computational and biochemical analyses, we propose that M2I-1 disturbs conformational dynamics of Mad2 critical for complex formation with Cdc20. Cellular studies revealed that M2I-1 weakens the SAC response, indicating that the compound might be active in cells. Thus, our study identifies the SAC specific complex formation between Mad2 and Cdc20 as a protein-protein interaction that can be targeted by small molecules.}, language = {en} } @article{AbdoAckermannAjelloetal.2011, author = {Abdo, A.

We find that the average Large Area Telescope (LAT) gamma-ray spectrum of Mrk 501 can be well described by a single power-law function with a photon index of 1.78 +/- 0.03. While we observe relatively mild flux variations with the Fermi-LAT (within less than a factor of two), we detect remarkable spectral variability where the hardest observed spectral index within the LAT energy range is 1.52 +/- 0.14, and the softest one is 2.51 +/- 0.20. These unexpected spectral changes do not correlate with the measured flux variations above 0.3 GeV. In this paper, we also present the first results from the 4.5 month long multifrequency campaign (2009 March 15-August 1) on Mrk 501, which included the Very Long Baseline Array (VLBA), Swift, RXTE, MAGIC, and VERITAS, the F-GAMMA, GASP-WEBT, and other collaborations and instruments which provided excellent temporal and energy coverage of the source throughout the entire campaign. The extensive radio to TeV data set from this campaign provides us with the most detailed spectral energy distribution yet collected for this source during its relatively low activity. The average spectral energy distribution of Mrk 501 is well described by the standard one-zone synchrotron self-Compton (SSC) model. In the framework of this model, we find that the dominant emission region is characterized by a size less than or similar to 0.1 pc (comparable within a factor of few to the size of the partially resolved VLBA core at 15-43 GHz), and that the total jet power (similar or equal to 10(44) erg s(-1)) constitutes only a small fraction (similar to 10(-3)) of the Eddington luminosity. The energy distribution of the freshly accelerated radiating electrons required to fit the time-averaged data has a broken power-law form in the energy range 0.3 GeV-10 TeV, with spectral indices 2.2 and 2.7 below and above the break energy of 20 GeV. We argue that such a form is consistent with a scenario in which the bulk of the energy dissipation within the dominant emission zone of Mrk 501 is due to relativistic, proton-mediated shocks. We find that the ultrarelativistic electrons and mildly relativistic protons within the blazar zone, if comparable in number, are in approximate energy equipartition, with their energy dominating the jet magnetic field energy by about two orders of magnitude.}, language = {en} } @article{BraunNagel2005, author = {Braun, Sebastian and Nagel, Michael}, title = {Zwischen Solidargemeinschaft und Dienstleistungsorganisation - Mitgliedschaft, Engagement, und Partizipation im Sportverein}, isbn = {3-7780-3375-1}, year = {2005}, language = {de} } @book{BaurBraunBurrmannetal.2003, author = {Baur, J{\"u}rgen and Braun, Sebastian and Burrmann, Ulrike and Nagel, Michael}, title = {Wer macht die Vereinspolitik in Sportvereinen?}, year = {2003}, language = {de} } @article{BraunNagel2003, author = {Braun, Sebastian and Nagel, Michael}, title = {Soziales Kapital und die assoziative Lebenswelt in Deutschland.

Therefore, fluorescent poly(organosiloxane) nanoparticles of 15 nm radius are synthesized, which are used as a scaffold for surface modification in a grafting onto approach. With multi-angle dynamic light scattering, asymmetrical flow field-flow fractionation, gel electrophoresis, and liquid chromatography-mass spectrometry, it is demonstrated that protein adsorption on PEtOxylated nanoparticles is extremely low, similar as on PEGylated nanoparticles. Moreover, quantitative microscopy reveals that PEtOxylation significantly reduces the non-specific cellular uptake, particularly by macrophage-like cells.

The present study explored whether the ET1- receptor ETB influences suicidal erythrocyte death. To this end, [Ca2+](i) (Fluo3-fluorescence) and phosphatidylserine exposure (annexin V-binding) were determined utilizing FACS analysis. Energy depletion increased [Ca2+]i and phosphatidylserine-exposure, effects significantly blunted by ET1 (IC50 approximate to 100 nM) and the ETB receptor- agonist sarafotoxin 6c (IC50 approximate to 10 nM) but not by ET2 and ET3. ET1 and sarafotoxin significantly delayed the kinetics of suicidal erythrocyte death following energy depletion. ETB stimulation did not blunt the effect of Ca2+- ionophore ionomycin (1 mu M) on phosphatidylserine exposure. The in vivo significance was tested using rescued ETB- knockout (etb(-/-)) and wild-type (etb(+/+)) mice. The number of phosphatidylserine-exposing erythrocytes, of reticulocytes and spleen size were significantly larger in etb(-/-) mice than in etb(+/+)-mice.

Einige davon wurden auf den vergangenen E-Learning Symposien der Universit{\"a}t Potsdam pr{\"a}sentiert: Das erste E-Learning Symposium im Jahr 2012 konzentrierte sich auf unterschiedliche M{\"o}glichkeiten der Studierendenaktivierung und Lehrgestaltung. Das Symposium 2014 r{\"u}ckte vor allem die Studierenden ins Zentrum der Aufmerksamkeit. Im Jahr 2016 kam es durch das Zusammengehen des Symposiums mit der DeLFI-Tagung zu einer Fokussierung auf technische Innovationen. Doch was ist aus den Leuchtt{\"u}rmen von gestern geworden, und brauchen wir {\"u}berhaupt noch neue Leuchtt{\"u}rme? Das Symposium setzt sich in diesem Jahr unter dem Motto „Innovation und Nachhaltigkeit - (k)ein Gegensatz?" mit mediengest{\"u}tzten Lehr- und Lernprozessen im universit{\"a}ren Kontext auseinander und reflektiert aktuelle technische sowie didaktische Entwicklungen mit Blick auf deren mittel- bis langfristigen Einsatz in der Praxis. Dieser Tagungsband zum E-Learning Symposium 2018 an der Universit{\"a}t Potsdam beinhaltet eine Mischung von Forschungs- und Praxisbeitr{\"a}gen aus verschiedenen Fachdisziplinen und er{\"o}ffnet vielschichtige Perspektiven auf das Thema E-Learning. Dabei werden die Vielfalt der didaktischen Einsatzszenarien als auch die Potentiale von Werk-zeugen und Methoden der Informatik in ihrem Zusammenspiel beleuchtet. In seiner Keynote widmet sich Reinhard Keil dem Motto des Symposiums und geht der Nachhaltigkeit bei E-Learning-Projekten auf den Grund. Dabei analysiert und beleuchtet er anhand seiner {\"u}ber 15-j{\"a}hrigen Forschungspraxis die wichtigsten Wirkfaktoren und formuliert Empfehlungen zur Konzeption von E-Learning-Projekten. Im Gegensatz zu rein auf Kostenersparnis ausgerichteten (hochschul-)politischen Forderungen proklamiert er den Ansatz der hypothesengeleiteten Technikgestaltung, in der Nachhaltigkeit als Leitfrage oder Forschungsstrategie verstanden werden kann. In eine {\"a}hnliche Richtung geht der Beitrag von Iris Braun et al., die {\"u}ber Erfolgsfaktoren beim Einsatz von Audience Response Systemen in der universit{\"a}ren Lehre berichten. Ein weiteres aktuelles Thema, sowohl f{\"u}r die Bildungstechnologie als auch in den Bildungswissenschaften allgemein, ist die Kompetenzorientierung und -modellierung. Hier geht es darum (Probleml{\"o}se-)F{\"a}higkeiten gezielt zu beschreiben und in den Mittelpunkt der Lehre zu stellen. Johannes Konert stellt in einem eingeladenen Vortrag zwei Projekte vor, die den Prozess beginnend bei der Definition von Kompetenzen, deren Modellierung in einem semantischen maschinenlesbaren Format bis hin zur Erarbeitung von Methoden zur Kompetenzmessung und der elektronischen Zertifizierung aufzeigen. Dabei geht er auf technische M{\"o}glichkeiten, aber auch Grenzen ein. Auf einer spezifischeren Ebene besch{\"a}ftigt sich Sarah Stumpf mit digitalen bzw. mediendidaktischen Kompetenzen im Lehramtsstudium und stellt ein Framework f{\"u}r die F{\"o}rderung ebensolcher Kompetenzen bei angehenden Lehrkr{\"a}ften vor. Der Einsatz von E-Learning birgt noch einige Herausforderungen. Dabei geht es oft um die Verbindung von Didaktik und Technik, den Erhalt von Aufmerksamkeit oder den Aufwand f{\"u}r das Erstellen von interaktiven Lehr- und Lerninhalten. Drei Beitr{\"a}ge in diesem Tagungsband besch{\"a}ftigen sich mit dieser Thematik in unterschiedlichen Kontexten und zeigen Best-Practices und L{\"o}sungsans{\"a}tze auf: Der Beitrag von Martina Wahl und Michael H{\"o}lscher behandelt den besonderen Kontext von Blended Learning-Szenarien in berufsbegleitenden Studieng{\"a}ngen. Um die Ver{\"o}ffentlichung eines global frei verf{\"u}gbaren Onlinekurses abseits der großen MOOC Plattformen und den didaktischen Herausforderungen auch hinsichtlich der Motivation geht es im Beitrag von Ennio Marani und Isabel Jaisli. Schließlich schlagen Gregor Damnik et al. die automatische Erzeugung von Aufgaben zur Erh{\"o}hung von Interaktivit{\"a}t und Adaptivit{\"a}t in digitalen Lernressourcen vor, um den teilweise erheblichen Erstellungsaufwand zu reduzieren. Zum Thema E-Learning z{\"a}hlen auch immer mobile Apps bzw. Spiele.

A number of modelling groups will be running isotope-enabled palaeoclimate simulations in the framework of the Coupled Model Intercomparison Project Phase 6, so it is timely to evaluate different approaches to using the speleothem data for data-model comparisons. Here, we illustrate this using 456 globally distributed speleothem δ18O records from an updated version of the Speleothem Isotopes Synthesis and Analysis (SISAL) database and palaeoclimate simulations generated using the ECHAM5-wiso isotope-enabled atmospheric circulation model. We show that the SISAL records reproduce the first-order spatial patterns of isotopic variability in the modern day, strongly supporting the application of this dataset for evaluating model-derived isotope variability into the past. However, the discontinuous nature of many speleothem records complicates the process of procuring large numbers of records if data-model comparisons are made using the traditional approach of comparing anomalies between a control period and a given palaeoclimate experiment. To circumvent this issue, we illustrate techniques through which the absolute isotope values during any time period could be used for model evaluation. Specifically, we show that speleothem isotope records allow an assessment of a model's ability to simulate spatial isotopic trends. Our analyses provide a protocol for using speleothem isotope data for model evaluation, including screening the observations to take into account the impact of speleothem mineralogy on δ18O values, the optimum period for the modern observational baseline and the selection of an appropriate time window for creating means of the isotope data for palaeo-time-slices.}, language = {en} } @article{DambacherDimigenBraunetal.2012, author = {Dambacher, Michael and Dimigen, Olaf and Braun, Mario and Wille, Kristin and Jacobs, Arthur M. and Kliegl, Reinhold}, title = {Stimulus onset asynchrony and the timeline of word recognition: Event-related potentials during sentence reading}, series = {Neuropsychologia : an international journal in behavioural and cognitive neuroscience}, volume = {50}, journal = {Neuropsychologia : an international journal in behavioural and cognitive neuroscience}, number = {8}, publisher = {Elsevier}, address = {Oxford}, issn = {0028-3932}, doi = {10.1016/j.neuropsychologia.2012.04.011}, pages = {1852 -- 1870}, year = {2012}, abstract = {Three ERP experiments examined the effect of word presentation rate (i.e., stimulus onset asynchrony, SOA) on the time course of word frequency and predictability effects in sentence reading. In Experiments 1 and 2, sentences were presented word-by-word in the screen center at an SOA of 700 and 490 ms, respectively. While these rates are typical for psycholinguistic ERP research, natural reading happens at a considerably faster pace. Accordingly. Experiment 3 employed a near-normal SOA of 280 ms, which approximated the rate of normal reading. Main results can be summarized as follows: (1) The onset latency of early frequency effects decreases gradually with increasing presentation rates. (2) An early interaction between top-down and bottom-up processing is observed only under a near-normal SOA. (3) N400 predictability effects occur later and are smaller at a near-normal (i.e., high) presentation rate than at the lower rates commonly used in ERP experiments. (4) ERP morphology is different at the shortest compared to longer SOAs. Together, the results point to a special role of a near-normal presentation rate for visual word recognition and therefore suggest that SOA should be taken into account in research of natural reading.}, language = {en} } @article{AbramowskiAceroAharonianetal.2012, author = {Abramowski, Attila and Acero, F. and Aharonian, Felix A. and Akhperjanian, A.

M 87 has been established as a VHE gamma-ray emitter since 2006. The VHE gamma-ray emission displays strong variability on timescales as short as a day. In this paper, results from a joint VHE monitoring campaign on M 87 by the MAGIC and VERITAS instruments in 2010 are reported. During the campaign, a flare at VHE was detected triggering further observations at VHE (H.E.S.S.), X-rays (Chandra), and radio (43 GHz Very Long Baseline Array, VLBA). The excellent sampling of the VHE gamma-ray light curve enables one to derive a precise temporal characterization of the flare: the single, isolated flare is well described by a two-sided exponential function with significantly different flux rise and decay times of tau(rise)(d) = (1.69 +/- 0.30) days and tau(decay)(d) = (0.611 +/- 0.080) days, respectively. While the overall variability pattern of the 2010 flare appears somewhat different from that of previous VHE flares in 2005 and 2008, they share very similar timescales (similar to day), peak fluxes (Phi(>0.35 TeV) similar or equal to (1-3) x 10(-11) photons cm(-2) s(-1)), and VHE spectra. VLBA radio observations of 43 GHz of the inner jet regions indicate no enhanced flux in 2010 in contrast to observations in 2008, where an increase of the radio flux of the innermost core regions coincided with a VHE flare. On the other hand, Chandra X-ray observations taken similar to 3 days after the peak of the VHE gamma-ray emission reveal an enhanced flux from the core (flux increased by factor similar to 2; variability timescale <2 days). The long-term (2001-2010) multi-wavelength (MWL) light curve of M 87, spanning from radio to VHE and including data from Hubble Space Telescope, Liverpool Telescope, Very Large Array, and European VLBI Network, is used to further investigate the origin of the VHE gamma-ray emission. No unique, common MWL signature of the three VHE flares has been identified. In the outer kiloparsec jet region, in particular in HST-1, no enhanced MWL activity was detected in 2008 and 2010, disfavoring it as the origin of the VHE flares during these years. Shortly after two of the three flares (2008 and 2010), the X-ray core was observed to be at a higher flux level than its characteristic range (determined from more than 60 monitoring observations: 2002-2009). In 2005, the strong flux dominance of HST-1 could have suppressed the detection of such a feature. Published models for VHE gamma-ray emission from M 87 are reviewed in the light of the new data.}, language = {en} }
