The results of the crystallographic analyses show distorted tetrahedral coordination geometry of all [CuCl4]2- anions in the five complexes and prove that all investigated complexes are stabilised by hydrogen bonds of different intensities. Despite the use of sterically demanding ammonium, phosphonium and arsonium cations to obtain the separation of the paramagnetic Cu(II) centres for EPR spectroscopy no hyperfine structure was observed in the EPR spectra but the principal values of the electron Zeeman tensor, g∥ and g⊥, could be determined.

The complex interplay of thermal convection, interface, and gravitational forces yields optimal turbulent mixing and transport. Domains of collapsed film are generated, elongated, and convected in a beautiful display of chaotic mixing.

In addition, recent research on colloids, interfaces and nanofluids led to advances in the development of micro-mixers (lab-on-a-chip devices). By the thermal forcing of a film, one can reach Rayleigh numbers in the turbulent regime, such that the experiment may serve as a prototype of a mixer on the basis of thermally induced turbulence in free-standing thin liquid films with thicknesses in the nanometer range. Here, the specific experimental results of a setup with a focus on the mixing statistics of a thermally driven two-dimensional thin film are presented. Our setup allows us to capture thin film interference patterns under controlled surface and atmospheric conditions. The convection is realized by placing a cooled copper rod in the center of the film. The temperature gradient between the rod and the atmosphere results in a density gradient in the liquid film, so that the varying buoyancy induces turbulent motion. The flow field is characterized by a newly developed algorithm-color imaging velocimetry (CIV). This analysis determines not only the velocity, but also the full deformation tensor in the Lagrangian frame. On the basis of these insights, the flow in the experiment was investigated with respect to its mixing properties: we calculated the mixing efficiency and entropy of the flow scheme to sufficiently high accuracy.}, language = {en} } @phdthesis{Winkler2013, author = {Winkler, Henning}, title = {Synthese von thermoplastisch verarbeitbaren Fetts{\"a}ure-Acylderivaten der St{\"a}rke und Proteine}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-71089}, school = {Universit{\"a}t Potsdam}, year = {2013}, abstract = {In den vergangenen Jahren wurden stetig wachsende Produktionskapazit{\"a}ten von Biokunststoffen aus nachwachsenden Rohstoffe nverzeichnet.

B. Polyestern Anwendung. Gleiches gilt f{\"u}r Kunststoffe auf Proteinbasis. Die vorliegende Arbeit hat die Entwicklung von Biokunststoffen auf St{\"a}rkebasis zum Ziel, welche ohne externe Weichmacher thermoplastisch verarbeitbar und hydrophob sind sowie ein mechanisches Eigenschaftsprofil aufweisen, welches ein Potenzial zur Herstellung von Materialien f{\"u}r eine Anwendung als Verpackungsmittel bietet. Um die Rohstoffbasis f{\"u}r Biokunststoffe zu erweitern, soll das erarbeitete Konzept auf zwei industriell verf{\"u}gbare Proteintypen, Zein und Molkenproteinisolat (WPI), {\"u}bertragen werden. Als geeignete Materialklasse wurden Fetts{\"a}ureester der St{\"a}rke herausgearbeitet. Zun{\"a}chst fand ein Vergleich der S{\"a}urechlorid-Veresterung und der Umesterung von Fetts{\"a}urevinylestern statt, woraus letztere als geeignetere Methode hervorging. Durch Variation der Reaktionsparameter konnte diese optimiert und auf eine Serie der Fetts{\"a}urevinylester von Butanoat bis Stearat f{\"u}r DS-Werte bis zu 2,2-2,6 angewandt werden. M{\"o}glich war somit eine systematische Studie unter Variation der veresterten Fetts{\"a}ure sowie des Substitutionsgrades (DS). S{\"a}mtliche Produkte mit einem DS ab 1,5 wiesen eine ausgpr{\"a}gte L{\"o}slichkeit in organischen L{\"o}sungsmitteln auf wodurch sowohl die Aufnahme von NMR-Spektren als auch Molmassenbestimmung mittels Gr{\"o}ßenausschlusschromatographie mit gekoppelter Mehrwinkel-Laserlichtstreuung (GPC-MALLS) m{\"o}glich waren. Durch dynamische Lichtstreuung (DLS) wurde das L{\"o}slichkeitsverhalten veranschaulicht. S{\"a}mtliche Produkte konnten zu Filmen verarbeitet werden, wobei Materialien mit DS 1,5-1,7 hohe Zugfestigkeiten (bis zu 42 MPa) und Elastizit{\"a}tsmodule (bis 1390 MPa) aufwiesen. Insbesondere St{\"a}rkehexanoat mit DS <2 sowie St{\"a}rkebutanoat mit DS >2 hatten ein mechanisches Eigenschaftsprofil, welches insbesondere in Bezug auf die Festigkeit/Steifigkeit vergleichbar mit Verpackungsmaterialien wie Polyethylen war (Zugfestigkeit: 15-32 MPa, E-Modul: 300-1300 MPa). Zugfestigkeit und Elastizit{\"a}tsmodul nahmen mit steigender Kettenl{\"a}nge der veresterten Fetts{\"a}ure ab. Ester l{\"a}ngerkettiger Fetts{\"a}uren (C16-C18) waren spr{\"o}de. {\"U}ber Weitwinkel-R{\"o}ntgenstreuung (WAXS) und Infrarotspektroskopie (ATR-FTIR) konnte der Verlauf der Festigkeiten mit einer zunehmenden Distanz der St{\"a}rke im Material begr{\"u}ndet werden. Es konnten von DS und Kettenl{\"a}nge abh{\"a}ngige Glas{\"u}berg{\"a}nge detektiert werden, die kristallinen Strukturen der langkettigen Fetts{\"a}uren zeigten einen Schmelzpeak.

Blends mit biobasierten Polyterpenen sowie den in der Arbeit hergestellten Zein-Acylderivaten erm{\"o}glichten eine weitere Verbesserung der Zugfestigkeit bzw. des Elastizit{\"a}tsmoduls hochsubstituierter Produkte. Eine thermoplastische Verarbeitung mittels Spritzgießen war sowohl f{\"u}r Produkte mit hohem als auch mittlerem DS-Wert ohne jeglichen Zusatz von Weichmachern m{\"o}glich. Es entstanden homogene, transparente Pr{\"u}fst{\"a}be. Untersuchungen der H{\"a}rte ergaben auch hier f{\"u}r St{\"a}rkehexanoat und -butanoat mit Polyethylen vergleichbare Werte. Ausgew{\"a}hlte Produkte wurden zu Fasern nach dem Schmelzspinnverfahren verarbeitet. Hierbei wurden insbesondere f{\"u}r hochsubstituierte Derivate homogenen Fasern erstellt, welche im Vergleich zur Gießfolie signifikant h{\"o}here Zugfestigkeiten aufwiesen. St{\"a}rkeester mit mittlerem DS ließen sich ebenfalls verarbeiten. Zun{\"a}chst wurden f{\"u}r eine {\"U}bertragung des Konzeptes auf die Proteine Zein und WPI verschiedene Synthesemethoden verglichen. Die Veresterung mit S{\"a}urechloriden ergab hierbei die h{\"o}chsten Werte. Im Hinblick auf eine gute L{\"o}slichkeit in organischen L{\"o}sungsmitteln wurde f{\"u}r WPI die Veresterung mit carbonyldiimidazol (CDI)-aktivierten Fetts{\"a}uren in DMSO und f{\"u}r Zein die Veresterung mit S{\"a}u-rechloriden in Pyridin bevorzugt. Es stellte sich heraus, dass acyliertes WPI zwar hydrophob, jedoch ohne Weichmacher nicht thermoplastisch verarbeitet werden konnte. Die Erstellung von Gießfolien f{\"u}hrte zu Spr{\"o}dbruchverhalten. Unter Zugabe der biobasierten {\"O}ls{\"a}ure wurde die Anwendung von acyliertem WPI als thermoplastischer Filler z.

Under conditions of air-level carbon dioxide concentration [CO2], a carbon concentrating mechanism (CCM) is induced to facilitate cellular carbon uptake. CCM increases the availability of carbon dioxide at the site of cellular carbon fixation. To improve our understanding of the transcriptional control of the CCM, we employed FAIRE-seq (formaldehyde-assisted Isolation of Regulatory Elements, followed by deep sequencing) to determine nucleosome-depleted chromatin regions of algal cells subjected to carbon deprivation. Our FAIRE data recapitulated the positions of known regulatory elements in the promoter of the periplasmic carbonic anhydrase (Cah1) gene, which is upregulated during CCM induction, and revealed new candidate regulatory elements at a genome-wide scale. In addition, time series expression patterns of 130 transcription factor (TF) and transcription regulator (TR) genes were obtained for cells cultured under photoautotrophic condition and subjected to a shift from high to low [CO2]. Groups of co-expressed genes were identified and a putative directed gene-regulatory network underlying the CCM was reconstructed from the gene expression data using the recently developed IOTA (inner composition alignment) method. Among the candidate regulatory genes, two members of the MYB-related TF family, Lcr1 (Low-CO2 response regulator 1) and Lcr2 (Low-CO2 response regulator 2), may play an important role in down-regulating the expression of a particular set of TF and TR genes in response to low [CO2]. The results obtained provide new insights into the transcriptional control of the CCM and revealed more than 60 new candidate regulatory genes. Deep sequencing of nucleosome-depleted genomic regions indicated the presence of new, previously unknown regulatory elements in the C. reinhardtii genome. Our work can serve as a basis for future functional studies of transcriptional regulator genes and genomic regulatory elements in Chlamydomonas.}, language = {en} } @article{WiesmeierPrietzelBartholdetal.2013, author = {Wiesmeier, Martin and Prietzel, J{\"o}rg and Barthold, Frauke Katrin and Sp{\"o}rlein, Peter and Geuss, Uwe and Hangen, Edzard and Reischl, Arthur and Schilling, Bernd and von L{\"u}tzow, Margit and K{\"o}gel-Knabner, Ingrid}, title = {Storage and drivers of organic carbon in forest soils of southeast Germany (Bavaria) - Implications for carbon sequestration}, series = {Forest ecology and management}, volume = {295}, journal = {Forest ecology and management}, number = {10}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0378-1127}, doi = {10.1016/j.foreco.2013.01.025}, pages = {162 -- 172}, year = {2013}, abstract = {Temperate forest soils of central Europe are regarded as important pools for soil organic carbon (SOC) and thought to have a high potential for carbon (C) sequestration.

In this study, we analyzed a forest data set of 596 completely sampled soil profiles down to the parent material or to a depth of 1 m within Bavaria in southeast Germany in order to determine representative SOC stocks under different forest types in central Europe and the impact of different environmental parameters. We calculated a total median SOC stock of 9.8 kg m(-2) which is considerably lower compared with many other inventories within central Europe that used modelled instead of measured soil properties. Statistical analyses revealed climate as controlling parameter for the storage of SOC with increasing stocks in cool, humid mountainous regions and a strong decrease in areas with higher temperatures. No significant differences of total SOC storage were found between broadleaf, coniferous and mixed forests. However, coniferous forests stored around 35\% of total SOC in the labile organic layer that is prone to human disturbance, forest fires and rising temperatures. In contrast, mixed and broadleaf forests stored the major part of SOC in the mineral soil. Moreover, these two forest types showed unchanged or even slightly increased mineral SOC stocks with higher temperatures, whereas SOC stocks in mineral soils under coniferous forest were distinctly lower. We conclude that mixed and broadleaf forests are more advantageous for C sequestration than coniferous forests.

However, there is a remarkable lack of information about the status quo of organic carbon in agricultural soils. In this study a comprehensive data set of 384 cropland soils and 333 grassland soils within the state of Bavaria in southeast Germany was analyzed in order to provide representative information on total amount, regional distribution and driving parameters of soil organic carbon (SOC) and nitrogen (N) in agricultural soils of central Europe. The results showed that grassland soils stored higher amounts of SOC (11.8 kg m(-2)) and N (0.92 kg m(-2)) than cropland soils (9.0 and 0.66 kg m(-2), respectively) due to moisture-induced accumulation of soil organic matter (SOM) in B horizons. Surprisingly, no distinct differences were found for the A horizons since tillage led to a relocation of SOM with depth in cropland soils. Statistical analyses of driving factors for SOM storage revealed soil moisture, represented by the topographic wetness index (TWI), as the most important parameter for both cropland and grassland soils. Climate effects (mean annual temperature and precipitation) were of minor importance in agricultural soils because management options counteracted them to a certain extent, particularly in cropland soils. The distribution of SOC and N stocks within Bavaria based on agricultural regions confirmed the importance of soil moisture since the highest cropland SOC and N stocks were found for tertiary hills and loess regions, which exhibited large areas with potentially high soil moisture content in extant floodplains. Grassland soils showed the highest accumulation of SOC and N in the Alps and Pre-Alps as a result of low temperatures, high amounts of precipitation and high soil moisture content in areas of glacial denudation. Soil class was identified as a further driving parameter for SOC and N storage in cropland soils. In total, cropland and grassland soils in Bavaria store 242 and 134 Mt SOC as well as 19 and 12 Mt N down to a soil depth of 1 m or the parent material, respectively.}, language = {en} } @phdthesis{Wiencke2013, author = {Wiencke, Fabian}, title = {Zur Legitimit{\"a}t von EU-Mehrheitsentscheidungen}, series = {Region - Nation - Europa}, volume = {73}, journal = {Region - Nation - Europa}, publisher = {LIT}, address = {Berlin}, isbn = {978-3-643-12249-0}, pages = {210 S.}, year = {2013}, language = {de} } @phdthesis{Wiemann2013, author = {Wiemann, Rebekka}, title = {Sexuelle Orientierung im V{\"o}lker- und Europarecht : zwischen kulturellem Relativismus und Universalismus}, series = {Menschenrechtszentrum der Universit{\"a}t Potsdam}, volume = {36}, journal = {Menschenrechtszentrum der Universit{\"a}t Potsdam}, publisher = {BWV Berliner Wiss.-Verl.}, address = {Berlin}, isbn = {978-3-8305-3121-0}, pages = {341 S.}, year = {2013}, language = {de} } @article{WiemannEckstein2013, author = {Wiemann, Dirk and Eckstein, Lars}, title = {Introduction : towards a cultural politics of passion}, isbn = {978-3-631-60196-9}, year = {2013}, language = {en} } @misc{Wiemann2013, author = {Wiemann, Dirk}, title = {Cities of the Mind - Villages of the Mind}, series = {Postprints der Universit{\"a}t Potsdam : Philosophische Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Philosophische Reihe}, number = {109}, issn = {1866-8380}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-93951}, pages = {14}, year = {2013}, abstract = {Deep into the second half of the twentieth century the traditionalist definition of India as a country of villages remained dominant in official political rhetoric as well as cultural production.

Here, we report evidence that the actin machinery of chemotactic Dictyostelium cells operates close to an oscillatory instability. When averaging the actin response of many cells to a short pulse of the chemoattractant cAMP, we observed a transient accumulation of cortical actin reminiscent of a damped oscillation. At the single-cell level, however, the response dynamics ranged from short, strongly damped responses to slowly decaying, weakly damped oscillations. Furthermore, in a small subpopulation, we observed self-sustained oscillations in the cortical F-actin concentration. To substantiate that an oscillatory mechanism governs the actin dynamics in these cells, we systematically exposed a large number of cells to periodic pulse trains of different frequencies. Our results indicate a resonance peak at a stimulation period of around 20 s. We propose a delayed feedback model that explains our experimental findings based on a time-delay in the regulatory network of the actin system. To test the model, we performed stimulation experiments with cells that express GFP-tagged fusion proteins of Coronin and actin-interacting protein 1, as well as knockout mutants that lack Coronin and actin-interacting protein 1. These actin-binding proteins enhance the disassembly of actin filaments and thus allow us to estimate the delay time in the regulatory feedback loop. Based on this independent estimate, our model predicts an intrinsic period of 20 s, which agrees with the resonance observed in our periodic stimulation experiments.}, language = {en} } @article{WessigMatthesSchildeetal.2013, author = {Wessig, Pablo and Matthes, Annika and Schilde, Uwe and Kelling, Alexandra}, title = {Asymmetric synthesis of (1,5)Naphthalenophanes by Dehydro-Diels-Alder reaction}, series = {European journal of organic chemistry}, journal = {European journal of organic chemistry}, number = {11}, publisher = {Wiley-VCH}, address = {Weinheim}, issn = {1434-193X}, doi = {10.1002/ejoc.201201594}, pages = {2123 -- 2129}, year = {2013}, abstract = {An asymmetric variant of the dehydro-Diels-Alder (DDA) reaction has been developed and applied in the atropselective synthesis of various (1,5)naphthalenophanes.

Therefore a proof for its existence and the revelation of its nature belongs to one of the most intriguing challenges of nowadays cosmology and particle physics. The present work tries to investigate the nature of dark matter through indirect signatures from dark matter annihilation into electron-positron pairs in two different ways, pressure from dark matter annihilation and multi-messenger constraints on the dark matter annihilation cross-section. We focus on dark matter annihilation into electron-positron pairs and adopt a model-independent approach, where all the electrons and positrons are injected with the same initial energy E_0 ~ m_dm*c^2. The propagation of these particles is determined by solving the diffusion-loss equation, considering inverse Compton scattering, synchrotron radiation, Coulomb collisions, bremsstrahlung, and ionization. The first part of this work, focusing on pressure from dark matter annihilation, demonstrates that dark matter annihilation into electron-positron pairs may affect the observed rotation curve by a significant amount. The injection rate of this calculation is constrained by INTEGRAL, Fermi, and H.E.S.S. data. The pressure of the relativistic electron-positron gas is computed from the energy spectrum predicted by the diffusion-loss equation. For values of the gas density and magnetic field that are representative of the Milky Way, it is estimated that the pressure gradients are strong enough to balance gravity in the central parts if E_0 < 1 GeV. The exact value depends somewhat on the astrophysical parameters, and it changes dramatically with the slope of the dark matter density profile. For very steep slopes, as those expected from adiabatic contraction, the rotation curves of spiral galaxies would be affected on kiloparsec scales for most values of E_0. By comparing the predicted rotation curves with observations of dwarf and low surface brightness galaxies, we show that the pressure from dark matter annihilation may improve the agreement between theory and observations in some cases, but it also imposes severe constraints on the model parameters (most notably, the inner slope of the halo density profile, as well as the mass and the annihilation cross-section of dark matter particles into electron-positron pairs). In the second part, upper limits on the dark matter annihilation cross-section into electron-positron pairs are obtained by combining observed data at different wavelengths (from Haslam, WMAP, and Fermi all-sky intensity maps) with recent measurements of the electron and positron spectra in the solar neighbourhood by PAMELA, Fermi, and H.E.S.S.. We consider synchrotron emission in the radio and microwave bands, as well as inverse Compton scattering and final-state radiation at gamma-ray energies. For most values of the model parameters, the tightest constraints are imposed by the local positron spectrum and synchrotron emission from the central regions of the Galaxy. According to our results, the annihilation cross-section should not be higher than the canonical value for a thermal relic if the mass of the dark matter candidate is smaller than a few GeV. In addition, we also derive a stringent upper limit on the inner logarithmic slope α of the density profile of the Milky Way dark matter halo (α < 1 if m_dm < 5 GeV, α < 1.3 if m_dm < 100 GeV and α < 1.5 if m_dm < 2 TeV) assuming a dark matter annihilation cross-section into electron-positron pairs (σv) = 3*10^-26 cm^3 s^-1, as predicted for thermal relics from the big bang.}, language = {en} } @article{Weber2013, author = {Weber, Sascha}, title = {Die kurmainzische Heeresreform von 1773}, volume = {2013}, number = {17/2}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-73255}, pages = {41 -- 70}, year = {2013}, language = {de} } @phdthesis{Weber2013, author = {Weber, Armin}, title = {Was ist Wirklichkeit?

Now, a new generation of DBD dyes has been developed. Although they are still sensitive to polarity, in contrast to the former DBD dyes, they have extraordinary spectroscopic properties even in aqueous surroundings. They are characterized by long fluorescence lifetimes (10-20ns), large Stokes shifts (approximate to 100nm), high photostabilities, and high quantum yields (>0.56). Here, the spectroscopic properties and synthesis of functionalized derivatives for labeling biological targets are described. Furthermore, thio-reactive maleimido derivatives of both DBD generations show strong intramolecular fluorescence quenching. This mechanism has been investigated and is found to undergo a photoelectron transfer (PET) process. After reaction with a thiol group, this fluorescence quenching is prevented, indicating successful bonding. Being sensitive to their environmental polarity, these compounds have been used as powerful fluorescence lifetime probes for the investigation of conformational changes in the maltose ATP-binding cassette transporter through fluorescence lifetime spectroscopy. The differing tendencies of the fluorescence lifetime change for both DBD dye generations promote their combination as a powerful toolkit for studying microenvironments in proteins.}, language = {en} } @phdthesis{Wawrzinek2013, author = {Wawrzinek, Robert C.

Progress has been made concerning the genes involved and the regulatory networks controlling senescence. The resulting complex metabolome changes during senescence have not been investigated in detail yet. Therefore, we conducted a comprehensive profiling of metabolites, including pigments, lipids, sugars, amino acids, organic acids, nutrient ions, and secondary metabolites, and determined approximately 260 metabolites at distinct stages in leaves and siliques during senescence in Arabidopsis (Arabidopsis thaliana). This provided an extensive catalog of metabolites and their spatiotemporal cobehavior with progressing senescence. Comparison with silique data provides clues to source-sink relations. Furthermore, we analyzed the metabolite distribution within single leaves along the basipetal sink-source transition trajectory during senescence. Ceramides, lysolipids, aromatic amino acids, branched chain amino acids, and stress-induced amino acids accumulated, and an imbalance of asparagine/aspartate, glutamate/glutamine, and nutrient ions in the tip region of leaves was detected. Furthermore, the spatiotemporal distribution of tricarboxylic acid cycle intermediates was already changed in the presenescent leaves, and glucosinolates, raffinose, and galactinol accumulated in the base region of leaves with preceding senescence.

However, whether and how species adapt to environmental changes remains unclear. By focusing on the realized niche (i.e. the actual space that a species inhabits and the resources it can access as a result of limiting biotic factors present in its habitat), we here examine shifts in the realized-niche width (i.e. ecological amplitude) and position (i.e. ecological optimum) of 26 common and widespread forest understorey plants across their distributional ranges. Location Temperate forests along a ca. 1800-km-long latitudinal gradient from northern France to central Sweden and Estonia. Methods We derived species' realized-niche width from a -diversity metric, which increases if the focal species co-occurs with more species. Based on the concept that species' scores in a detrended correspondence analysis (DCA) represent the locations of their realized-niche positions, we developed a novel approach to run species-specific DCAs allowing the focal species to shift its realized-niche position along the studied latitudinal gradient while the realized-niche positions of other species were held constant. Results None of the 26 species maintained both their realized-niche width and position along the latitudinal gradient. Few species (9 of 26: 35\%) shifted their realized-niche width, but all shifted their realized-niche position. With increasing latitude, most species (22 of 26: 85\%) shifted their realized-niche position for soil nutrients and pH towards nutrient-poorer and more acidic soils. Main conclusions Forest understorey plants shifted their realized niche along the latitudinal gradient, suggesting local adaptation and/or plasticity. This macroecological pattern casts doubt on the idea that the realized niche is stable in space and time, which is a key assumption of species distribution models used to predict the future of biodiversity, hence raising concern about predicted extinction rates.}, language = {en} } @unpublished{Warschburger2013, author = {Warschburger, Petra}, title = {Nutrition in children and adolescents}, series = {Zeitschrift f{\"u}r Gesundheitspsychologie}, volume = {21}, journal = {Zeitschrift f{\"u}r Gesundheitspsychologie}, number = {2}, publisher = {Hogrefe}, address = {G{\"o}ttingen}, issn = {0943-8149}, pages = {49 -- 52}, year = {2013}, language = {de} } @article{Warlen2013, author = {Warlen, Maria V.}, title = {Die Widerspiegelung des Abgeordnetenstatus in den Entscheidungen des Verfassungsgerichts der Russischen F{\"o}deration}, series = {Verfassungsgerichtsbarkeit in der Russischen F{\"o}deration und in der Bundesrepublik Deutschland : Rundtischgespr{\"a}ch an der Moskauer Staatlichen Juristischen Kutafin-Universit{\"a}t am 9. und 10.

NT-26 is a bioenergetic enzyme involved in the oxidation of arsenite to arsenate. The enzyme from the distantly related heterotroph, Alcaligenes faecalis, which is thought to oxidise arsenite for detoxification, consists of a large alpha subunit (AioA) with bis-molybdopterin guanine dinucleotide at its active site and a 3Fe-4S cluster, and a small beta subunit (AioB) which contains a Rieske 2Fe-2S cluster. The successful heterologous expression of the NT-26 Aio in Escherichia coli has resulted in the solution of its crystal structure. The NT-26 Aio, a heterotetramer, shares high overall similarity to the heterodimeric arsenite oxidase from A. faecalis but there are striking differences in the structure surrounding the Rieske 2Fe-2S cluster which we demonstrate explains the difference in the observed redox potentials (+225 mV vs. +130/160 mV, respectively). A combination of site-directed mutagenesis and electron paramagnetic resonance was used to explore the differences observed in the structure and redox properties of the Rieske cluster. In the NT-26 AioB the substitution of a serine (S126 in NT-26) for a threonine as in the A. faecalis AioB explains a -20 mV decrease in redox potential. The disulphide bridge in the A. faecalis AioB which is conserved in other betaproteobacterial AioB subunits and the Rieske subunit of the cytochrome bc(1) complex is absent in the NT-26 AioB subunit. The introduction of a disulphide bridge had no effect on Aio activity or protein stability but resulted in a decrease in the redox potential of the cluster. These results are in conflict with previous data on the betaproteobacterial AioB subunit and the Rieske of the bc(1) complex where removal of the disulphide bridge had no effect on the redox potential of the former but a decrease in cluster stability was observed in the latter.}, language = {en} } @article{Warditz2013, author = {Warditz, Vladislava Maria}, title = {The linguistic Reception of the French Novel in Russia the Phenomenon of the Argot in Hugo's Les Miserables and in Krestovskij's Peterburgskie truscoby}, series = {Zeitschrift f{\"u}r Slawistik}, volume = {58}, journal = {Zeitschrift f{\"u}r Slawistik}, number = {4}, publisher = {De Gruyter}, address = {Berlin}, issn = {0044-3506}, doi = {10.1524/slaw.2013.58.4.391}, pages = {391 -- 416}, year = {2013}, language = {de} } @phdthesis{Wang2013, author = {Wang, Ting}, title = {A novel R2R3 MYB-like transcription factor regulates ABA mediated stress response and leaf growth in Arabidopsis}, address = {Potsdam}, pages = {102 S.}, year = {2013}, language = {en} } @article{WangFritzschBernardingetal.2013, author = {Wang, Jing and Fritzsch, Claire and Bernarding, Johannes and Krause, Thomas and Mauritz, Karl-Heinz and Brunetti, Maddalena and Dohle, Christian}, title = {Cerebral activation evoked by the mirror illusion of the hand in stroke patients compared to normal subjects}, series = {Neurorehabilitation : an interdisciplinary journal}, volume = {33}, journal = {Neurorehabilitation : an interdisciplinary journal}, number = {4}, publisher = {IOS Press}, address = {Amsterdam}, issn = {1053-8135}, doi = {10.3233/NRE-130999}, pages = {593 -- 603}, year = {2013}, abstract = {BACKGROUND: Mirror therapy (MT) was found to improve motor function after stroke, but its neural mechanisms remain unclear, especially in single stroke patients. OBJECTIVES: The following imaging study was designed to compare brain activation patterns evoked by the mirror illusion in single stroke patients with normal subjects. METHODS: Fifteen normal volunteers and five stroke patients with severe arm paresis were recruited. Cerebral activations during movement mirroring by means of a video chain were recorded with functional magnetic resonance imaging (fMRI). Single-subject analysis was performed using SPM 8. RESULTS: For normal subjects, ten and thirteen subjects displayed lateralized cerebral activations evoked by the mirror illusion while moving their right and left hand respectively. The magnitude of this effect in the precuneus contralateral to the seen hand was not dependent on movement speed or subjective experience. Negative correlation of activation strength with age was found for the right hand only. The activation pattern in stroke patients is comparable to that of normal subjects and present in four out of five patients. CONCLUSIONS: In summary, the mirror illusion can elicit cerebral activation contralateral to the perceived hand in the majority of single normal subjects, but not in all of them.

In particular, there has been intensive debate concerning whether the artifact accumulation at the Middle Pleistocene Olorgesailie (Southern Kenya Rift) and Kariandusi (Central Kenya Rift) sites were a result of fluvial reworking or of in situ deposition by hominids. We used a two-step approach to test the hypothesis of fluvial reworking. Firstly, the behavior of handaxes in water currents was investigated in a current flume and the flow threshold required to reorientate the handaxes was determined. The results of these experiments suggested that, in relatively high energy and non-steady flow conditions, handaxes will reorientate themselves perpendicular to the current direction. Secondly, an automated image analysis routine was developed and applied to archeological plans from three Acheulean sites, two at Olorgesailie and one at Kariandusi, in order to determine the orientations of the handaxes. A Rayleigh test was then applied to the orientation data to test for a preferred orientation. The results revealed that the handaxes at the Upper Kariandusi Site and the Olorgesailie Main Site Mid Trench had a preferential orientation, suggesting reworking by a paleocurrent. The handaxes from the Olorgesailie Main Site H/6A, however, appeared to be randomly oriented and in situ deposition by the producers therefore remains a possibility.}, language = {en} } @unpublished{Wallenta2013, author = {Wallenta, Daniel}, title = {A Lefschetz fixed point formula for elliptic quasicomplexes}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-67016}, year = {2013}, abstract = {In a recent paper with N.

But N. spumigena also is common in brackish water bodies worldwide, suggesting special adaptation allowing it to thrive at moderate salinities. A draft genome analysis of N. spumigena sp. CCY9414 yielded a single scaffold of 5,462,271 nucleotides in length on which genes for 5,294 proteins were annotated. A subsequent strand-specific transcriptome analysis identified more than 6,000 putative transcriptional start sites (TSS). Orphan TSSs located in intergenic regions led us to predict 764 non-coding RNAs, among them 70 copies of a possible retrotransposon and several potential RNA regulators, some of which are also present in other N2-fixing cyanobacteria. Approximately 4\% of the total coding capacity is devoted to the production of secondary metabolites, among them the potent hepatotoxin nodularin, the linear spumigin and the cyclic nodulapeptin. The transcriptional complexity associated with genes involved in nitrogen fixation and heterocyst differentiation is considerably smaller compared to other Nostocales. In contrast, sophisticated systems exist for the uptake and assimilation of iron and phosphorus compounds, for the synthesis of compatible solutes, and for the formation of gas vesicles, required for the active control of buoyancy. Hence, the annotation and interpretation of this sequence provides a vast array of clues into the genomic underpinnings of the physiology of this cyanobacterium and indicates in particular a competitive edge of N. spumigena in nutrient-limited brackish water ecosystems.}, language = {en} } @article{VorpahlDislichElsenbeeretal.2013, author = {Vorpahl, Peter and Dislich, Claudia and Elsenbeer, Helmut and M{\"a}rker, Michael and Schr{\"o}der-Esselbach, Boris}, title = {Biotic controls on shallow translational landslides}, series = {Earth surface processes and landforms : the journal of the British Geomorphological Research Group}, volume = {38}, journal = {Earth surface processes and landforms : the journal of the British Geomorphological Research Group}, number = {2}, publisher = {Wiley-Blackwell}, address = {Hoboken}, issn = {0197-9337}, doi = {10.1002/esp.3320}, pages = {198 -- 212}, year = {2013}, abstract = {In undisturbed tropical montane rainforests massive organic layers accommodate the majority of roots and only a small fraction of roots penetrate the mineral soil.

By distinguishing mineral soil, organic layer and above-ground biomass, it is shown that in this environment vegetation provides a destabilizing effect mainly due to its contribution to the mass of the organic layer (up to 973 t ha-1 under wet conditions). Sensitivity analysis shows that the destabilizing effect of the mass of soil and vegetation can only be effective on slopes steeper than 37.9 degrees. This situation applies to 36\% of the study area.

By adapting the hydrological model to a 3-hourly temporal scale, the flood forecasting can benefit from available meteorological forecasts with finer temporal resolution and can better represent critical events of short duration and at small spatial scales. By consulting the temporal patterns of a High-Resolution Limited-Area Model (HIRLAM) hindcast series for northern Europe with an hourly temporal and a 0.1 degrees spatial resolution, existing daily 1 x 1km(2) grids for temperature and precipitation covering all of Norway (the seNorge data) were disaggregated into 3-hourly values for the time period September 1957 to December 2010.

The results show that the disaggregated data perform best with anomaly correlation coefficients between 0.89 and 0.92 for temperature.

Our results confirm a surprising prediction of the good-enough account: high-capacity readers commit to an attachment decision more often than low-capacity participants, leading to more errors and a greater need to reanalyse in garden-path sentences. These results emerged only when we separated functionally different types of regressive eye movements using a scanpath analysis; conventional eye-tracking measures alone would have led to different conclusions. The scanpath analysis also showed that rereading was the dominant strategy for recovering from garden-pathing.

Road corridors function as routes of secondary dispersal for many plant species but the extent to which vehicles support this process remains unclear.

We exposed marked seeds of four species on a section of road and drove a car along the road at a speed of 48 km/h. By tracking seeds we quantified movement parallel as well as lateral to the road, resulting dispersal kernels, and the effect of repeated vehicle passes. Median distances travelled by seeds along the road were about eight meters for species with wind dispersal morphologies and one meter for species without such adaptations. Airflow created by the car lifted seeds and resulted in longitudinal dispersal. Single seeds reached our maximum measuring distance of 45 m and for some species exceeded distances under primary dispersal. Mathematical models were fit to dispersal kernels. The incremental effect of passing vehicles on longitudinal dispersal decreased with increasing number of passes as seeds accumulated at road verges. We conclude that dispersal by vehicle airflow facilitates seed movement along roads and accumulation of seeds in roadside habitats.

For this purpose, methyl 10-undecenoate, which can be obtained by pyrolysis of castor oil, was used in olefin cross-metathesis under neat conditions forming an unsaturated a,?-acetoxy ester. A catalyst screening with 11 different ruthenium-based metathesis catalysts was performed, revealing that well-suited catalysts allow for full conversion and very good cross-metathesis selectivity at a loading of only 0.5?mol\%. An alternative possibility to the aforementioned synthetic method is a palladium-catalyzed reaction of methyl 10-undecenoate with acetic acid in the presence of dimethyl sulfoxide. Here, the formation of linear and branched unsaturated acetoxy esters as well as a ketone was observed. The conversion as well as the selectivity of this procedure was studied under different reaction conditions and compared to the cross-metathesis results. Based on the successful functionalization of methyl 10-undecenoate, methyl oleate was investigated in this palladium-catalyzed C?H activation reaction. Due to the lower reactivity of the internal double bond the desired acetoxy ester was only obtained in moderate conversion in this case. In summary, this study clearly shows that palladium-catalyzed functionalization of unsaturated fatty compounds via C?H activation is an attractive alternative to the well-established olefin cross-metathesis procedure.}, language = {en} } @misc{Vogl2013, author = {Vogl, Janna}, title = {Social workers, communities and politics : Akteursperspektiven von NGO-Gr{\"u}ndern und -Gr{\"u}nderinnen in S{\"u}dindien}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-68922}, year = {2013}, abstract = {Gegenstand dieser Arbeit sind die (Selbst-)Darstellungen von Gr{\"u}nder_innen von Nichtregierungsorganisationen (NGOs) im Bereich Kinder- und Frauenrechte in Tamil Nadu, S{\"u}dindien.

The adaptation engine often describes the adaptation by using runtime models representing relevant aspects of the adaptable software and particular activities such as analysis and planning that operate on these runtime models. To systematically address the interplay between runtime models and adaptation activities in adaptation engines, runtime megamodels have been proposed for self-adaptive software. A runtime megamodel is a specific runtime model whose elements are runtime models and adaptation activities. Thus, a megamodel captures the interplay between multiple models and between models and activities as well as the activation of the activities. In this article, we go one step further and present a modeling language for ExecUtable RuntimE MegAmodels (EUREMA) that considerably eases the development of adaptation engines by following a model-driven engineering approach. We provide a domain-specific modeling language and a runtime interpreter for adaptation engines, in particular for feedback loops. Megamodels are kept explicit and alive at runtime and by interpreting them, they are directly executed to run feedback loops. Additionally, they can be dynamically adjusted to adapt feedback loops. Thus, EUREMA supports development by making feedback loops, their runtime models, and adaptation activities explicit at a higher level of abstraction. Moreover, it enables complex solutions where multiple feedback loops interact or even operate on top of each other. Finally, it leverages the co-existence of self-adaptation and off-line adaptation for evolution.}, language = {en} } @phdthesis{Vogel2013, author = {Vogel, Kristin}, title = {Applications of Bayesian networks in natural hazard assessments}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-69777}, school = {Universit{\"a}t Potsdam}, year = {2013}, abstract = {Even though quite different in occurrence and consequences, from a modeling perspective many natural hazards share similar properties and challenges. Their complex nature as well as lacking knowledge about their driving forces and potential effects make their analysis demanding: uncertainty about the modeling framework, inaccurate or incomplete event observations and the intrinsic randomness of the natural phenomenon add up to different interacting layers of uncertainty, which require a careful handling. Nevertheless deterministic approaches are still widely used in natural hazard assessments, holding the risk of underestimating the hazard with disastrous effects. The all-round probabilistic framework of Bayesian networks constitutes an attractive alternative. In contrast to deterministic proceedings, it treats response variables as well as explanatory variables as random variables making no difference between input and output variables. Using a graphical representation Bayesian networks encode the dependency relations between the variables in a directed acyclic graph: variables are represented as nodes and (in-)dependencies between variables as (missing) edges between the nodes. The joint distribution of all variables can thus be described by decomposing it, according to the depicted independences, into a product of local conditional probability distributions, which are defined by the parameters of the Bayesian network. In the framework of this thesis the Bayesian network approach is applied to different natural hazard domains (i.e. seismic hazard, flood damage and landslide assessments). Learning the network structure and parameters from data, Bayesian networks reveal relevant dependency relations between the included variables and help to gain knowledge about the underlying processes. The problem of Bayesian network learning is cast in a Bayesian framework, considering the network structure and parameters as random variables itself and searching for the most likely combination of both, which corresponds to the maximum a posteriori (MAP score) of their joint distribution given the observed data. Although well studied in theory the learning of Bayesian networks based on real-world data is usually not straight forward and requires an adoption of existing algorithms. Typically arising problems are the handling of continuous variables, incomplete observations and the interaction of both. Working with continuous distributions requires assumptions about the allowed families of distributions. To "let the data speak" and avoid wrong assumptions, continuous variables are instead discretized here, thus allowing for a completely data-driven and distribution-free learning. An extension of the MAP score, considering the discretization as random variable as well, is developed for an automatic multivariate discretization, that takes interactions between the variables into account. The discretization process is nested into the network learning and requires several iterations. Having to face incomplete observations on top, this may pose a computational burden. Iterative proceedings for missing value estimation become quickly infeasible. A more efficient albeit approximate method is used instead, estimating the missing values based only on the observations of variables directly interacting with the missing variable. Moreover natural hazard assessments often have a primary interest in a certain target variable. The discretization learned for this variable does not always have the required resolution for a good prediction performance. Finer resolutions for (conditional) continuous distributions are achieved with continuous approximations subsequent to the Bayesian network learning, using kernel density estimations or mixtures of truncated exponential functions. All our proceedings are completely data-driven. We thus avoid assumptions that require expert knowledge and instead provide domain independent solutions, that are applicable not only in other natural hazard assessments, but in a variety of domains struggling with uncertainties.}, language = {en} } @book{VoethHerbstAustenetal.2013, author = {Voeth, Markus and Herbst, Uta and Austen, Viola and Becker, Tatjana and Bertels, Victoria and Heigl, Julia and Huttelmaier, Hannes and Kugler, Aline and Loos, Jeanette and Meister, Christoph and Rentner, Bj{\"o}rn and Richter, Jenny and Schmidt, Natalie and Schwarz, Daniela and schwarz, Sabine}, title = {Marketing-Managment : Grundlagen, Konzeption und Umsetzung}, publisher = {Sch{\"a}ffer-Poeschel Verlag}, address = {Stuttgart}, isbn = {978-3-7910-3271-9}, pages = {684 S.}, year = {2013}, language = {de} } @article{VockKoellerNagy2013, author = {Vock, Miriam and K{\"o}ller, Olaf and Nagy, Gabriel}, title = {Vocational interests of intellectually gifted and highly achieving young adults}, series = {British journal of educational psychology}, volume = {83}, journal = {British journal of educational psychology}, number = {2}, publisher = {Wiley-Blackwell}, address = {Hoboken}, issn = {0007-0998}, doi = {10.1111/j.2044-8279.2011.02063.x}, pages = {305 -- 328}, year = {2013}, abstract = {Background.Vocational interests play a central role in the vocational decision-making process and are decisive for the later job satisfaction and vocational success.

Further, the impact of intelligence and achievement on interests were analysed while statistically controlling for potentially influencing variables. Changes in interests over time were investigated. Sample.N= 4,694 German students (age: M= 19.5, SD= .80; 54.6\% females) participated in the study (TOSCA; Koller, Watermann, Trautwein, \& Ludtke, 2004). Method.

Results.Gifted participants reported stronger investigative and realistic interests, but lower social interests than less intelligent participants. Highly achieving participants reported higher investigative and (in wave 2) higher artistic interests. Considerable gender differences were found: gifted girls had a flat interest profile, while gifted boys had pronounced realistic and investigative and low social interests. Multilevel multiple regression analyses predicting interests by intelligence and school achievement revealed stable interest profiles. Beyond a strong gender effect, intelligence and school achievement each contributed substantially to the prediction of vocational interests. Conclusions.At the time around graduation from high school, gifted young adults show stable interest profiles, which strongly differ between gender and intelligence groups.

The bulk of pre-mRNAs are processed by canonical nuclear poly(A) polymerase (PAPS). Both vertebrate and higher-plant genomes encode more than one isoform of this enzyme, and these are coexpressed in different tissues. However, in neither case is it known whether the isoforms fulfill different functions or polyadenylate distinct subsets of pre-mRNAs. Here we show that the three canonical nuclear PAPS isoforms in Arabidopsis are functionally specialized owing to their evolutionarily divergent C-terminal domains. A strong loss-of-function mutation in PAPS1 causes a male gametophytic defect, whereas a weak allele leads to reduced leaf growth that results in part from a constitutive pathogen response. By contrast, plants lacking both PAPS2 and PAPS4 function are viable with wild-type leaf growth. Polyadenylation of SMALL AUXIN UP RNA (SAUR) mRNAs depends specifically on PAPS1 function. The resulting reduction in SAUR activity in paps1 mutants contributes to their reduced leaf growth, providing a causal link between polyadenylation of specific pre-mRNAs by a particular PAPS isoform and plant growth. This suggests the existence of an additional layer of regulation in plant and possibly vertebrate gene expression, whereby the relative activities of canonical nuclear PAPS isoforms control de novo synthesized poly(A) tail length and hence expression of specific subsets of mRNAs.}, language = {en} } @phdthesis{Verma2013, author = {Verma, Meetu}, title = {The evolution and decay of sunspots : a hight-resolution study of flows and magnetic fields in and around sunspots}, address = {Potsdam}, pages = {112 S.}, year = {2013}, language = {en} } @phdthesis{Verhounig2013, author = {Verhounig, Andreas}, title = {Riboswitche f{\"u}r die konditionale Genexpression in Bakterien und Plastiden}, address = {Potsdam}, pages = {138 S.}, year = {2013}, language = {de} } @misc{VasishthvonderMalsburgEngelmann2013, author = {Vasishth, Shravan and von der Malsburg, Titus Raban and Engelmann, Felix}, title = {What eye movements can tell us about sentence comprehension}, series = {Wiley interdisciplinary reviews : Cognitive Science}, volume = {4}, journal = {Wiley interdisciplinary reviews : Cognitive Science}, number = {2}, publisher = {Wiley}, address = {San Fransisco}, issn = {1939-5078}, doi = {10.1002/wcs.1209}, pages = {125 -- 134}, year = {2013}, abstract = {Eye movement data have proven to be very useful for investigating human sentence processing.

However, there are some limitations regarding the inferences that can be made on the basis of eye movements. One relates to the nontrivial interaction between parsing and the eye movement control system which complicates the interpretation of eye movement data. Detailed computational models that integrate parsing with eye movement control theories have the potential to unpack the complexity of eye movement data and can therefore aid in the interpretation of eye movements. Another limitation is the difficulty of capturing spatiotemporal patterns in eye movements using the traditional word-based eyetracking measures. Recent research has demonstrated the relevance of these patterns and has shown how they can be analyzed.

The aim is to use DIBs as diagnostics of the local interstellar conditions, whilst at the same time deriving properties of the yet-unknown carriers of these enigmatic spectral features. Methods. Spectra of over 800 early-type stars from the Very Large Telescope Flames Tarantula Survey (VFTS) were analysed. Maps were created, separately, for the Galactic and LMC absorption in the DIBs at 4428 and 6614 angstrom and - in a smaller region near the central cluster R 136 - neutral sodium (the Na ID doublet); we also measured the DIBs at 5780 and 5797 angstrom. Results. The maps show strong 4428 and 6614 angstrom DIBs in the quiescent cloud complex to the south of 30 Dor but weak absorption in the harsher environments to the north (bubbles) and near the OB associations. The Na maps show at least five kinematic components in the LMC and a shell-like structure surrounding R 136, and small-scale structure in the Milky Way. The strengths of the 4428, 5780, 5797 and 6614 angstrom DIBs are correlated, also with Na absorption and visual extinction. The strong 4428 angstrom DIB is present already at low Na column density but the 6614, 5780 and 5797 angstrom DIBs start to be detectable at subsequently larger Na column densities. Conclusions. The carriers of the 4428, 6614, 5780 and 5797 angstrom DIBs are increasingly prone to removal from irradiated gas. The relative strength of the 5780 and 5797 angstrom DIBs clearly confirm the Tarantula Nebula as well as Galactic high-latitude gas to represent a harsh radiation environment. The resilience of the 4428 angstrom DIB suggests its carrier is large, compact and neutral. Structure is detected in the distribution of cool-warm gas on scales between one and > 100 pc in the LMC and as little as 0.01 pc in the Sun's vicinity. Stellar winds from the central cluster R 136 have created an expanding shell; some infalling gas is also detected, reminiscent of a galactic "fountain".}, language = {en} } @article{vanLeeuwenKern2013, author = {van Leeuwen, Judith and Kern, Kristine}, title = {The External Dimension of European Union Marine Governance: Institutional Interplay between the EU and the International Maritime Organization}, series = {Global environmental politics}, volume = {13}, journal = {Global environmental politics}, number = {1}, publisher = {MIT Press}, address = {Cambridge}, issn = {1526-3800}, doi = {10.1162/GLEP_a_00154}, pages = {69 -- +}, year = {2013}, abstract = {This article focuses on the emergence of a decentralized institutional complex, interplay management, and the institutional interplay between the International Maritime Organization (IMO) and the EU in the issue area of environmental shipping policies.

This paper offers an in-depth analysis of how a locally developed vocabulary can be successfully reconciled with the Library of Congress Subject Headings (LCSH) and the Arts and Architecture Thesaurus (AAT) through the help of a general-purpose tool for interactive data transformation (OpenRefine).

The younger lamprophyre and trachyte dikes (c. 68-70 Ma) imply that tensional stresses in the Western Province were either renewed at this time, or that extension and related magmatism continued during opening of the Tasman Sea. Extension-related magmatism in the region not only preceded Tasman seafloor spreading initiation (starting at c. 83 Ma, lasting to c. 53 Ma), but may have sporadically continued for up to 15 Ma after continental break-up.}, language = {en} } @article{vandeVijverBaerHenney2013, author = {van de Vijver, Ruben and Baer-Henney, Dinah}, title = {On the role of phonetic motivation and frequency in the acquisition of alternations}, series = {Zeitschrift f{\"u}r Literaturwissenschaft und Linguistik}, volume = {43}, journal = {Zeitschrift f{\"u}r Literaturwissenschaft und Linguistik}, number = {169}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Stuttgart}, issn = {0049-8653}, pages = {49 -- 64}, year = {2013}, abstract = {On the Role of Phonetic Motivation and Frequency in the Acquisition of Alternations German nouns may alternate in two ways: a final word-final voiceless obstruent in the singular may correspond to a voiced one in the plural and a back vowel in the singular may correspond to a front one in the plural. We investigate the role of phonetic motivation and frequency in the acquisition of these alternations. The voicing alternation has a phonetic motivation, but the vowel alternation does not. On the basis of two corpus studies, we conclude that both alternations occur with equal frequency in the ambient language. In two production experiments, one with 5-year-olds and one with adults, we asked both populations to form plurals for given singular words and nonces. The children produce more voicing alternations in nonces than adults and fewer vowel alternations than adults. We conclude that children rely more on phonetic motivation than adults.}, language = {en} } @article{VanBelProostVanNesteetal.2013, author = {Van Bel, Michiel and Proost, Sebastian and Van Neste, Christophe and Deforce, Dieter and Van de Peer, Yves and Vandepoele, Klaas}, title = {TRAPID - an efficient online tool for the functional and comparative analysis of de novo RNA-Seq transcriptomes}, series = {Genome biology : biology for the post-genomic era}, volume = {14}, journal = {Genome biology : biology for the post-genomic era}, number = {12}, publisher = {BioMed Central}, address = {London}, issn = {1465-6906}, doi = {10.1186/gb-2013-14-12-r134}, pages = {10}, year = {2013}, abstract = {Transcriptome analysis through next-generation sequencing technologies allows the generation of detailed gene catalogs for non-model species, at the cost of new challenges with regards to computational requirements and bioinformatics expertise.
