Captured individuals were tested for ectoparasitic infestation. The aim was to update the fauna of ectoparasites of this state and to collect data on the distribution of individual species. Regarding this, results of previous surveys are summarised. In the present study nine out of thirteen bat species were found to be infested with a total of one flea species, one species of bat flies and eight species of mites. The infestation with fleas was below the expectations. Six spinturnicid mite species out of those occurring in Germany could be ascertained for Saxony-Anhalt. These are Spinturnix acuminatus (Koch, 1836), S. andegavinus (Kolenati, 1857), S. helvetiae Deunff, Keller \& Aellen, 1986, S. mystacinus (Kolenati, 1857), S. plecotinus (Koch, 1839) and S. puncata (Sundevall, 1833). Details about the infestation with parasites (abundances) of the respective bat species are presented. Further information on the biology of spinturnicid mites are given and infestation characteristics are compared with those of other surveys.

The respective orbits of systems A (O9.7 I+b2 v, P-A = 21 days) and B (O8 III+o9 v, P-B = 6 days) are reasonably well sampled by the observations, allowing the origin of the X-ray emission to be examined in detail. The X-ray spectra can be well fitted by an attenuated three-temperature thermal plasma model, characterized by cool, moderate, and hot plasma components at kT similar or equal to 0.2, 0.7, and 2 keV, respectively, and a circumstellar absorption of similar or equal to 0.2 x 10(22) cm(-2). Although the hot plasma component could be indicating the presence of wind-wind collision shocks in the system, the model fluxes calculated from spectral fits, with an average value of similar or equal to 7x10(-13) erg s(-1) cm(-2), do not show a clear correlation with the orbits of the two constituent binaries. A semi-analytical model of QZ Car reveals that a stable momentum balance may not be established in either system A or B. Yet, despite this, system B is expected to produce an observed X-ray flux well in excess of the observations. If one considers the wind of the O8 III star to be disrupted by mass transfer, the model and observations are in far better agreement, which lends support to the previous suggestion of mass transfer in the O8 III+o9 v binary.

Our study shows that the X-ray properties of known strongly magnetic stars are diverse: while some comply to the predictions of the magnetically confined wind model, others do not. We conclude that strong, hard, and variable X-ray emission may be a sufficient attribute of magnetic massive stars, but it is not a necessary one. We address the general properties of X-ray emission from "normal" massive stars, especially the long standing mystery about the correlations between the parameters of X-ray emission and fundamental stellar properties. The recent development in stellar structure modeling shows that small-scale surface magnetic fields may be common. We suggest a "hybrid" scenario which could explain the X-ray emission from massive stars by a combination of magnetic mechanisms on the surface and shocks in the stellar wind. The magnetic mechanisms and the wind shocks are triggered by convective motions in sub-photospheric layers. This scenario opens the door for a natural explanation of the well established correlation between bolometric and X-ray luminosities.}, language = {en} } @article{FiehlerBannertBischoffetal.2011, author = {Fiehler, Katja and Bannert, Michael M. and Bischoff, Matthias and Blecker, Carlo and Stark, Rudolf and Vaitl, Dieter and Franz, Volker H. and Roesler, Frank}, title = {Working memory maintenance of grasp-target information in the human posterior parietal cortex}, series = {NeuroImage : a journal of brain function}, volume = {54}, journal = {NeuroImage : a journal of brain function}, number = {3}, publisher = {Elsevier}, address = {San Diego}, issn = {1053-8119}, doi = {10.1016/j.neuroimage.2010.09.080}, pages = {2401 -- 2411}, year = {2011}, abstract = {Event-related functional magnetic resonance imaging was applied to identify cortical areas involved in maintaining target information in working memory used for an upcoming grasping action.

The right inferior parietal cortex demonstrated sustained neural activity throughout the delay, which overlapped with activity observed during encoding of the grasp target. Immediate and delayed grasping activated similar motor-related brain areas and showed no differential activity. The results suggest that the right inferior parietal cortex plays an important functional role in working memory maintenance of grasp-related information.

Methods Entrepreneurs (n = 632), teachers (n = 5,196), and physicians (n = 549) were surveyed in a cross-sectional design. The questionnaire Work-related Behavior and Experience Patterns (AVEM) was used for all professions and, in addition, two scales (health prevention and self-confidence) from the Checklist for Entrepreneurs in the sample of entrepreneurs. Results The largest proportion of the entrepreneurs (45\%) presented with a healthy pattern (compared with 18.4\% teachers and 18.3\% physicians). Thirty-eight percent of entrepreneurs showed a risk pattern of overexertion and stress, followed by teachers (28.9\%) and physicians (20.6\%). Unambitious or burnout patterns were seen in only 9.3/8.2\% of entrepreneurs, respectively, and 25.3/27.3\% of teachers, and 39.6/21.5\% of physicians. While the distribution of patterns in teachers and physicians differed significantly between genders, a gender difference was not found among entrepreneurs. Entrepreneurs with the risk pattern of overexertion scored significantly (P < 0.01) lower in self-confidence and health care than those with the healthy pattern. Conclusions The development of a successful enterprise depends, in part, on the health of the entrepreneur. The large proportion of entrepreneurs with the healthy pattern irrespective of gender may support the notion that self-selection effects of healthy individuals in this special career might be important. At the same time, a large proportion was at risk for overexertion and might benefit from measures to cope with professional demands and stress and promote a healthy behavior pattern.}, language = {en} } @unpublished{Lenz2011, author = {Lenz, Markus Alexander}, title = {Word makes tribe: - racism and determinism in the philology of the 19th century}, series = {Romanistische Zeitschrift f{\"u}r Literaturgeschichte}, volume = {35}, journal = {Romanistische Zeitschrift f{\"u}r Literaturgeschichte}, number = {3-4}, publisher = {Winter}, address = {Heidelberg}, issn = {0343-379X}, pages = {483 -- 484}, year = {2011}, language = {de} } @article{MuellerKoszinskiBrenningetal.2011, author = {Mueller, Marina Elsa Herta and Koszinski, Sylvia and Brenning, Alexander and Verch, Gernot and Korn, Ulrike and Sommer, Michael}, title = {Within-field variation of mycotoxin contamination of winter wheat is related to indicators of soil moisture}, series = {Plant and soil}, volume = {342}, journal = {Plant and soil}, number = {1-2}, publisher = {Springer}, address = {Dordrecht}, issn = {0032-079X}, doi = {10.1007/s11104-010-0695-5}, pages = {289 -- 300}, year = {2011}, abstract = {Humidity is an important determinant of the mycotoxin production (DON, ZEA) by Fusarium species in the grain ears. From a landscape perspective humidity is not evenly distributed across fields. The topographically-controlled redistribution of water within a single field rather leads to spatially heterogeneous soil water content and air humidity. Therefore we hypothesized that the spatial distribution of mycotoxins is related to these topographically-controlled factors. To test this hypothesis we studied the mycotoxin concentrations at contrasting topographic relief positions, i.e. hilltops and depressions characterized by soils of different soil moisture regimes, on ten winter wheat fields in 2006 and 2007. Maize was the preceding crop and minimum tillage was practiced in the fields. The different topographic positions were associated with moderate differences in DON and ZEA concentrations in 2006, but with significant differences in 2007, with six times higher median ZEA and two times higher median DON detected at depression sites compared to the hilltops. The depression sites correspond to a higher topographic wetness index as well as redoximorphic properties in soil profiles, which empirically supports our hypothesis at least for years showing wetter conditions in sensitive time windows for Fusarium infections.}, language = {en} } @book{Kraemer2011, author = {Kr{\"a}mer, Raimund}, title = {Wissenschaftliches Schreiben}, series = {WeltTrends-Lehrtexte}, volume = {4}, journal = {WeltTrends-Lehrtexte}, publisher = {Univ.-Verl.}, address = {Potsdam}, isbn = {978-3-941880-30-6}, issn = {1861-5139}, pages = {74 S.}, year = {2011}, language = {de} } @book{Kraemer2011, author = {Kr{\"a}mer, Raimund}, title = {Wissenschaftliches Schreiben}, edition = {4., {\"u}berarb.

As a promising alternative, we discuss behavioral, neuroscientific, and neuropsychological evidence in support of finger counting as the most likely initial determinant of SNAs.

Trait-based approaches often rely on the tacit assumption that intraspecific trait variability (ITV) is negligible compared to interspecific variability, so that species can be characterized by mean trait values. Yet, numerous recent studies have challenged this assumption by showing that ITV significantly affects various ecological processes. Accounting for ITV may thus strengthen trait-based approaches, but measuring trait values on a large number of individuals per species and site is not feasible. Therefore, it is important and timely to synthesize existing knowledge on ITV in order to (1) decide critically when ITV should be considered, and (2) establish methods for incorporating this variability. Here we propose a practical set of rules to identify circumstances under which ITV should be accounted for. We formulate a spatial trait variance partitioning hypothesis to highlight the spatial scales at which ITV cannot be ignored in ecological studies. We then refine a set of four consecutive questions on the research question, the spatial scale, the sampling design, and the type of studied traits, to determine case-by-case if a given study should quantify ITV and test its effects. We review methods for quantifying ITV and develop a step-by-step guideline to design and interpret simulation studies that test for the importance of ITV. Even in the absence of quantitative knowledge on ITV, its effects can be assessed by varying trait values within species within realistic bounds around the known mean values. We finish with a discussion of future requirements to further incorporate ITV within trait-based approaches. This paper thus delineates a general framework to account for ITV and suggests a direction towards a more quantitative trait-based ecology.}, language = {en} } @article{vonderMalsburgVasishth2011, author = {von der Malsburg, Titus Raban and Vasishth, Shravan}, title = {What is the scanpath signature of syntactic reanalysis?}, series = {Journal of memory and language}, volume = {65}, journal = {Journal of memory and language}, number = {2}, publisher = {Elsevier}, address = {San Diego}, issn = {0749-596X}, doi = {10.1016/j.jml.2011.02.004}, pages = {109 -- 127}, year = {2011}, abstract = {Which repair strategy does the language system deploy when it gets garden-pathed, and what can regressive eye movements in reading tell us about reanalysis strategies? Several influential eye-tracking studies on syntactic reanalysis (Frazier \& Rayner, 1982; Meseguer, Carreiras, \& Clifton, 2002; Mitchell, Shen, Green, \& Hodgson, 2008) have addressed this question by examining scanpaths, i.e., sequential patterns of eye fixations. However, in the absence of a suitable method for analyzing scanpaths, these studies relied on simplified dependent measures that are arguably ambiguous and hard to interpret. We address the theoretical question of repair strategy by developing a new method that quantifies scanpath similarity. Our method reveals several distinct fixation strategies associated with reanalysis that went undetected in a previously published data set (Meseguer et al., 2002). One prevalent pattern suggests re-parsing of the sentence, a strategy that has been discussed in the literature (Frazier \& Rayner, 1982); however, readers differed tremendously in how they orchestrated the various fixation strategies. Our results suggest that the human parsing system non-deterministically adopts different strategies when confronted with the disambiguating material in garden-path sentences.}, language = {en} } @phdthesis{CamaraMattosMartins2011, author = {Camara Mattos Martins, Marina}, title = {What are the downstream targets of trehalose-6-phosphate signalling in plants?}, address = {Potsdam}, pages = {164 S.}, year = {2011}, language = {en} } @phdthesis{Brunner2011, author = {Brunner, Beatrice}, title = {Wettbewerb im Stromnetz : der Netzanschlussanspruch nach \S 17 EnWG}, series = {Schriftenreihe Institut f{\"u}r Energie- und Wettbewerbsrecht in der Kommunalen Wirtschaft e.V. an de}, volume = {42}, journal = {Schriftenreihe Institut f{\"u}r Energie- und Wettbewerbsrecht in der Kommunalen Wirtschaft e.V. an de}, publisher = {Nomos}, address = {Baden-Baden}, isbn = {978-3-8329-6027-8}, pages = {612 S.}, year = {2011}, language = {de} } @article{GlatzelLaschewskyLutz2011, author = {Glatzel, Stefan and Laschewsky, Andr{\´e} and Lutz, Jean-Francois}, title = {Well-Defined uncharged polymers with a sharp UCST in water and in physiological milieu}, series = {Macromolecules : a publication of the American Chemical Society}, volume = {44}, journal = {Macromolecules : a publication of the American Chemical Society}, number = {2}, publisher = {American Chemical Society}, address = {Washington}, issn = {0024-9297}, doi = {10.1021/ma102677k}, pages = {413 -- 415}, year = {2011}, language = {en} } @article{Martens2011, author = {Martens, D{\"o}rte}, title = {Well-being and acceptance - contradictory aims in forest management?}, series = {Eco.mont : journal on protected mountain areas research}, volume = {3}, journal = {Eco.mont : journal on protected mountain areas research}, number = {2}, publisher = {Austrian Academy of Sciences Press}, address = {Wien}, issn = {2073-106X}, pages = {63 -- 65}, year = {2011}, abstract = {Urban forests fulfil various functions, among them the restoration process and aesthetical needs of urban residents.

For local, high resolution field modelling, they need to be combined with the surface gravity data. Such models are then used for various applications, from the study of the Earth interior to the determination of oceanic currents. Here we show how to realize such a combination in a flexible way using spherical wavelets and applying a domain decomposition approach. This iterative method, based on the Schwarz algorithms, allows to split a large problem into smaller ones, and avoids the calculation of the entire normal system, which may be huge if high resolution is sought over wide areas. A subdomain is defined as the harmonic space spanned by a subset of the wavelet family. Based on the localization properties of the wavelets in space and frequency, we define hierarchical subdomains of wavelets at different scales. On each scale, blocks of subdomains are defined by using a tailored spatial splitting of the area. The data weighting and regularization are iteratively adjusted for the subdomains, which allows to handle heterogeneity in the data quality or the gravity variations. Different levels of approximations of the subdomains normals are also introduced, corresponding to building local averages of the data at different resolution levels. We first provide the theoretical background on domain decomposition methods. Then, we validate the method with synthetic data, considering two kinds of noise: white noise and coloured noise. We then apply the method to data over Japan, where we combine a satellite-based geopotential model, EIGEN-GL04S, and a local gravity model from a combination of land and marine gravity data and an altimetry-derived marine gravity model. A hybrid spherical harmonics/wavelet model of the geoid is obtained at about 15 km resolution and a corrector grid for the surface model is derived.}, language = {en} } @book{OPUS4-33489, title = {Was Papst und Kaiser durch ihr Wort besch{\"u}tzen : das Zisterzienserkloster Dobrilugk in mittelalterlichen Urkunden und Siegeln}, series = {Einzelver{\"o}ffentlichungen des Brandenburgischen Landeshauptarchiv}, volume = {13}, journal = {Einzelver{\"o}ffentlichungen des Brandenburgischen Landeshauptarchiv}, editor = {Heimann, Heinz-Dieter and Neitmann, Klaus}, publisher = {Brandenburgisches Landeshauptarchiv}, address = {Potsdam}, isbn = {978-3-9810642-8-5}, pages = {32 S.}, year = {2011}, abstract = {Die vielgestaltige Geschichte des Klosters Dobrilugk wird anhand einer Auswahl kl{\"o}sterlicher Urkunden, die sich heute im Brandenburgischen Landeshauptarchiv befinden, dargestellt.

Little is known about changes in serum concentration after living donor kidney transplantation (LDKT) as a consequence of unilateral nephrectomy; although an association of these parameters with the risk of cardiovascular diseases and insulin resistance has been suggested. Therefore we analyzed the concentration of retinol, RBP4, apoRBP4 and transthyretin in serum of 20 living-kidney donors and respective recipients at baseline as well as 6 weeks and 6 months after LDKT. Results: As a consequence of LDKT, the kidney function of recipients was improved while the kidney function of donors was moderately reduced within 6 weeks after LDKT. With regard to vitamin A metabolism, the recipients revealed higher levels of retinol, RBP4, transthyretin and apoRBP4 before LDKT in comparison to donors. After LDKT, the levels of all four parameters decreased in serum of the recipients, while retinol, RBP4 as well as apoRBP4 serum levels of donors increased and remained increased during the follow-up period of 6 months. Conclusion: LDKT is generally regarded as beneficial for allograft recipients and not particularly detrimental for the donors. However, it could be demonstrated in this study that a moderate reduction of kidney function by unilateral nephrectomy, resulted in an imbalance of components of vitamin A metabolism with a significant increase of retinol and RBP4 and apoRBP4 concentration in serum of donors.}, language = {en} } @article{AwadWeidlichWeske2011, author = {Awad, Ahmed Mahmoud Hany Aly and Weidlich, Matthias and Weske, Mathias}, title = {Visually specifying compliance rules and explaining their violations for business processes}, series = {Journal of visual languages and computing}, volume = {22}, journal = {Journal of visual languages and computing}, number = {1}, publisher = {Elsevier}, address = {London}, issn = {1045-926X}, doi = {10.1016/j.jvlc.2010.11.002}, pages = {30 -- 55}, year = {2011}, abstract = {A business process is a set of steps designed to be executed in a certain order to achieve a business value.

However, business processes must also adhere to and show compliance with various regulations and constraints, the so-called compliance requirements. These are domain-dependent requirements. In many situations, verifying compliance on a model level is of great value, since violations can be resolved in an early stage prior to execution. However, this calls for using formal verification techniques, e.g., model checking, that are too complex for business experts to apply. In this paper, we utilize a visual language. BPMN-Q to express compliance requirements visually in a way similar to that used by business experts to build process models.

In the past, both ground-based gamma-ray telescopes VERITAS and MAGIC have reported detections of TeV emission near the apastron phases of the binary orbit. The observations presented here show no strong evidence for TeV emission during these orbital phases; however, during observations taken in late 2010, significant emission was detected from the source close to the phase of superior conjunction (much closer to periastron passage) at a 5.6 standard deviation (5.6 sigma) post-trials significance. In total, between 2008 October and 2010 December a total exposure of 64.5 hr was accumulated with VERITAS on LS I + 61 degrees 303, resulting in an excess at the 3.3 sigma significance level for constant emission over the entire integrated data set. The flux upper limits derived for emission during the previously reliably active TeV phases (i.e., close to apastron) are less than 5\% of the Crab Nebula flux in the same energy range. This result stands in apparent contrast to previous observations by both MAGIC and VERITAS which detected the source during these phases at 10\% of the Crab Nebula flux. During the two year span of observations, a large amount of X-ray data were also accrued on LS I + 61 degrees 303 by the Swift X-ray Telescope and the Rossi X-ray Timing Explorer Proportional Counter Array. We find no evidence for a correlation between emission in the X-ray and TeV regimes during 20 directly overlapping observations.

Each burst is analyzed independently in two modes: over the whole duration of the observations and again over a shorter timescale determined by the maximum VERITAS sensitivity to a burst with a t(-1.5) time profile. This temporal model is characteristic of GRB afterglows with high-energy, long-lived emission that have been detected by the Large Area Telescope on board the Fermi satellite. No significant very high energy (VHE) gamma-ray emission was detected and upper limits above the VERITAS threshold energy are calculated. The VERITAS upper limits are corrected for gamma-ray extinction by the extragalactic background light and interpreted in the context of the keV emission detected by Swift.

To identify these features, global and regional differential TEC maps based on global 2-h TEC maps provided by NASA in the IONEX format were plotted. For the considered earthquake, long-lived disturbances, presumably of seismic origin, were localized in the near-epicenter area and were accompanied by similar effects in the magnetoconjugate region. Both decreases and increases in the local TEC over the period from 22 UT of January 10 to 08 UT of January 12, 2010 were observed. The horizontal dimensions of the anomalies were similar to 40A degrees in longitude and similar to 20A degrees in latitude, with the magnitude of TEC disturbances reaching similar to 40\% relative to the background near the epicenter and more than 50\% in the magnetoconjugate area.

Hence, stocks are often used as indicators of ecosystem functions although the latter are generally more strongly related to rates than to stocks. The regulation of stocks and rates and thus their variability over time may differ, as stocks constitute the net result of production and losses. Based on long-term high frequency measurements in a large, deep lake we explore the variability patterns in primary and bacterial production and relate them to those of the corresponding standing stocks, i.e. chlorophyll concentration, phytoplankton and bacterial biomass. We employ different methods (coefficient of variation, spline fitting and spectral analysis) which complement each other for assessing the variability present in the plankton data, at different temporal scales. In phytoplankton, we found that the overall variability of primary production is dominated by fluctuations at low frequencies, such as the annual, whereas in stocks and chlorophyll in particular, higher frequencies contribute substantially to the overall variance. This suggests that using standing stocks instead of rate measures leads to an under- or overestimation of food shortage for consumers during distinct periods of the year. The range of annual variation in bacterial production is 8 times greater than biomass, showing that the variability of bacterial activity (e.g. oxygen consumption, remineralisation) would be underestimated if biomass is used. The P/B ratios were variable and although clear trends are present in both bacteria and phytoplankton, no systematic relationship between stock and rate measures were found for the two groups. Hence, standing stock and process rate measures exhibit different variability patterns and care is needed when interpreting the mechanisms and implications of the variability encountered.}, language = {en} } @article{KoethAppelhansRobertsonetal.2011, author = {Koeth, Anja and Appelhans, Dietmar and Robertson, Daniela and Tiersch, Brigitte and Koetz, Joachim}, title = {Use of weakly cationic dendritic glycopolymer for morphological transformation of phospholipid vesicles into tube-like networks}, series = {Soft matter}, volume = {7}, journal = {Soft matter}, number = {22}, publisher = {Royal Society of Chemistry}, address = {Cambridge}, issn = {1744-683X}, doi = {10.1039/c1sm06439h}, pages = {10581 -- 10584}, year = {2011}, abstract = {Using cationic polyelectrolytes with different molecular architectures, only hyperbranched poly(ethyleneimine) with maltose shell is suited to tailor the morphological transformation of anionic vesicles into tube-like networks.

These technologies are required for the high packing density of today's integrated circuits. Therefore the investigation of defect states in these structures is crucial. In this work we present X-ray synchrotron measurements, with an energy resolution which is about 5-10 times higher than is attainable with standard spectrometers, of amorphous alumina. We demonstrate that our experimental results are in agreement with calculated spectra of amorphous alumina which we have generated by stochastic quenching. This first principles method, which we have recently developed, is found to be superior to molecular dynamics in simulating the rapid gas to solid transition that takes place as this material is deposited for thin film applications. We detect and analyze in detail states in the band gap that originate from oxygen pairs. Similar states were previously found in amorphous alumina by other spectroscopic methods and were assigned to oxygen vacancies claimed to act mutually as electron and hole traps. The oxygen pairs which we probe in this work act as hole traps only and will influence the information retention in electronic devices. In amorphous silica oxygen pairs have already been found, thus they may be a feature which is characteristic also of other amorphous metal oxides.}, language = {en} } @unpublished{KroeningMargariaWoodcock2011, author = {Kr{\"o}ning, Daniel and Margaria, Tiziana and Woodcock, Jim}, title = {Untitled}, series = {Formal aspects of computing : the international journal of formal methods}, volume = {23}, journal = {Formal aspects of computing : the international journal of formal methods}, number = {5}, publisher = {Springer}, address = {New York}, issn = {0934-5043}, doi = {10.1007/s00165-011-0201-8}, pages = {585 -- 588}, year = {2011}, language = {en} } @article{Hoffmann2011, author = {Hoffmann, Michael}, title = {Unterrichtsideen zur textorientierten Wortschatzarbeit : Textsortentypische W{\"o}rter und Wortverbindungen}, isbn = {978-3-8340-0506-9}, year = {2011}, language = {de} } @phdthesis{Neuhaeuser2011, author = {Neuh{\"a}user, Christian}, title = {Unternehmen als moralische Akteure}, series = {Suhrkamp Taschenbuch Wissenschaft}, volume = {1999}, journal = {Suhrkamp Taschenbuch Wissenschaft}, publisher = {Suhrkamp}, address = {Berlin}, isbn = {978-3-518-29599-1}, pages = {352 S.}, year = {2011}, language = {de} } @article{Heimann2011, author = {Heimann, Heinz-Dieter}, title = {Unter den Kronensammlern : die Mark Brandenburg im Herrschaftsgef{\"u}ge der Dynastien der Wittelsbacher und Luxemburger}, year = {2011}, language = {de} } @article{HempelKoseskaNikoloskietal.2011, author = {Hempel, Sabrina and Koseska, Aneta and Nikoloski, Zoran and Kurths, J{\"u}rgen}, title = {Unraveling gene regulatory networks from time-resolved gene expression data - a measures comparison study}, series = {BMC bioinformatics}, volume = {12}, journal = {BMC bioinformatics}, number = {1}, publisher = {BioMed Central}, address = {London}, issn = {1471-2105}, doi = {10.1186/1471-2105-12-292}, pages = {26}, year = {2011}, abstract = {Background: Inferring regulatory interactions between genes from transcriptomics time-resolved data, yielding reverse engineered gene regulatory networks, is of paramount importance to systems biology and bioinformatics studies. Accurate methods to address this problem can ultimately provide a deeper insight into the complexity, behavior, and functions of the underlying biological systems. However, the large number of interacting genes coupled with short and often noisy time-resolved read-outs of the system renders the reverse engineering a challenging task. Therefore, the development and assessment of methods which are computationally efficient, robust against noise, applicable to short time series data, and preferably capable of reconstructing the directionality of the regulatory interactions remains a pressing research problem with valuable applications. Results: Here we perform the largest systematic analysis of a set of similarity measures and scoring schemes within the scope of the relevance network approach which are commonly used for gene regulatory network reconstruction from time series data. In addition, we define and analyze several novel measures and schemes which are particularly suitable for short transcriptomics time series. We also compare the considered 21 measures and 6 scoring schemes according to their ability to correctly reconstruct such networks from short time series data by calculating summary statistics based on the corresponding specificity and sensitivity. Our results demonstrate that rank and symbol based measures have the highest performance in inferring regulatory interactions. In addition, the proposed scoring scheme by asymmetric weighting has shown to be valuable in reducing the number of false positive interactions. On the other hand, Granger causality as well as information-theoretic measures, frequently used in inference of regulatory networks, show low performance on the short time series analyzed in this study. Conclusions: Our study is intended to serve as a guide for choosing a particular combination of similarity measures and scoring schemes suitable for reconstruction of gene regulatory networks from short time series data. We show that further improvement of algorithms for reverse engineering can be obtained if one considers measures that are rooted in the study of symbolic dynamics or ranks, in contrast to the application of common similarity measures which do not consider the temporal character of the employed data. Moreover, we establish that the asymmetric weighting scoring scheme together with symbol based measures (for low noise level) and rank based measures (for high noise level) are the most suitable choices.}, language = {en} } @article{SeemuellerFiehlerRoesler2011, author = {Seem{\"u}ller, Anna and Fiehler, Katja and R{\"o}sler, Frank}, title = {Unimodal and crossmodal working memory representations of visual and kinesthetic movement trajectories}, series = {Acta psychologica : international journal of psychonomics}, volume = {136}, journal = {Acta psychologica : international journal of psychonomics}, number = {1}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0001-6918}, doi = {10.1016/j.actpsy.2010.09.014}, pages = {52 -- 59}, year = {2011}, abstract = {The present study investigated whether visual and kinesthetic stimuli are stored as multisensory or modality-specific representations in unimodal and crossmodal working memory tasks.

One caveat for International Relations theorists is that none of the aforementioned authors intends to provide theoretical frameworks for his examination. However, since IR theory has damagingly neglected history in the last decades, the works under review here, at least in part, compensate for this disciplinary and intellectual failure. In conclusion, Freedman's in-depth approach as a diplomatic historian, with its underlying reference to the various traditions in US foreign policy thinking, is most illuminating, while Parsi's contestable account focuses too narrowly on the Iran-Israel relationship.

We consider deterministic and nondeterministic variants and distinguish four working modes. It is known that these systems in the most general mode are as powerful as one-way multi-head finite automata. It is additionally known that the number of heads corresponds to the number of automata in PCFAs in a constructive way. Thus, undecidability results as well as results on the hierarchies induced by the number of heads carry over from multi-head finite automata to PCFAs in the most general mode. Here, we complement these undecidability and hierarchy results also for the remaining working modes. In particular, we show that classical decidability questions are not semi-decidable for any type of PCFAs under consideration. Moreover, it is proven that the number of automata in the system induces infinite hierarchies for deterministic and nondeterministic PCFAs in three working modes.}, language = {en} } @phdthesis{Seyfried2011, author = {Seyfried, Markus}, title = {Unabh{\"a}ngigkeit und Wirksamkeit von Landesrechnungsh{\"o}fen : eine empirisch-vergleichende Bestandsaufnahme}, series = {Interdisziplin{\"a}re Organisations- und Verwaltungsforschung}, volume = {17}, journal = {Interdisziplin{\"a}re Organisations- und Verwaltungsforschung}, publisher = {VS Verlag f{\"u}r Sozialwissenschaften / Springer Fachmedien Wiesbaden GmbH Wiesbaden}, address = {Wiesbaden}, isbn = {978-3-531-92799-2}, doi = {10.1007/978-3-531-92799-2}, pages = {288 S.}, year = {2011}, language = {de} } @article{Ette2011, author = {Ette, Ottmar}, title = {Un episodio en la vida del pintor viajero : mala literatura y escritura fulminante en C{\´e}sar Aira}, issn = {0020-4536}, year = {2011}, language = {es} } @article{Ette2011, author = {Ette, Ottmar}, title = {Un episodio en la vida del pintor viajero : mala literatura y escritura fulminante en Cesar Aira}, year = {2011}, language = {es} } @phdthesis{Schumann2011, author = {Schumann, Birte}, title = {Umwelt- und bilanzrechtliche Grundlagen von nichtfinanziellen {\"o}kologischen Leistungsindikatoren : in den Gesch{\"a}ftsberichten im Verh{\"a}ltnis zum Gesamtsystem der Umweltberichterstattung von Unternehmen}, publisher = {Uni-Edition}, address = {Berlin}, isbn = {978-3-942171-25-0}, pages = {223 S.}, year = {2011}, language = {de} } @article{RadziukSkirtachGessneretal.2011, author = {Radziuk, Darya and Skirtach, Andre and Gessner, Andre and Kumke, Michael Uwe and Zhang, Wei and M{\"o}hwald, Helmuth and Shchukin, Dmitry}, title = {Ultrasonic Approach for Formation of Erbium Oxide Nanoparticles with Variable Geometries}, series = {Langmuir}, volume = {27}, journal = {Langmuir}, number = {23}, publisher = {American Chemical Society}, address = {Washington}, issn = {0743-7463}, doi = {10.1021/la203622u}, pages = {14472 -- 14480}, year = {2011}, abstract = {Ultrasound (20 kHz, 29 W. cm(-2)) is employed to form three types of erbium oxide nanoparticles in the presence of multiwalled carbon nanotubes as a template material in water. The nanoparticles are (i) erbium carboxioxide nanoparticles deposited on the external walls of multiwalled carbon nanotubes and Er(2)O(3) in the bulk with (ii) hexagonal and (iii) spherical geometries. Each type of ultrasonically formed nanoparticle reveals Er(3+) photoluminescence from crystal lattice. The main advantage of the erbium carboxioxide nanoparticles on the carbon nanotubes is the electromagnetic emission in the visible region, which is new and not examined up to the present date. On the other hand, the photoluminescence of hexagonal erbium oxide nanoparticles is long-lived (mu s) and enables the higher energy transition ((4)S(3/2)-(4)I(15/2)), which is not observed for spherical nanoparticles. Our work is unique because it combines for the first time spectroscopy of Er(3+) electronic transitions in the host crystal lattices of nanoparticles with the geometry established by ultrasound in aqueous solution of carbon nanotubes employed as a template material. The work can be of great interest for "green" chemistry synthesis of photoluminescent nanoparticles in water.}, language = {en} }
