In three experiments, participants had to detect a physically large (or small) target item among physically small (or large) distractors in a search task comprising single-digit numbers. The relative numerical size of the digits was varied, such that the target item was either among the numerically large or small numbers in the search display and the relation between numerical and physical size was either congruent or incongruent. Perceptual differences of the stimuli were controlled by a condition in which participants had to search for a differently coloured target item with the same physical size and by the usage of LCD-style numbers that were matched in visual similarity by shape transformations. The results of all three experiments consistently revealed that detecting a physically large target item is significantly faster when the numerical size of the target item is large as well (congruent), compared to when it is small (incongruent). This novel finding of a size congruity effect in visual search demonstrates an interaction between numerical and physical size in an experimental setting beyond typically used binary comparison tasks, and provides important new evidence for the notion of shared cognitive codes for numbers and sensorimotor magnitudes. Theoretical consequences for recent models on attention, magnitude representation and their interactions are discussed.}, language = {en} } @misc{BullHeurichSaveljevetal.2016, author = {Bull, James K. and Heurich, Marco and Saveljev, Alexander P. and Schmidt, Krzysztof and Fickel, J{\"o}rns and F{\"o}rster, Daniel W.}, title = {The effect of reintroductions on the genetic variability in Eurasian lynx populations}, series = {Postprints der Universit{\"a}t Potsdam : Mathematisch Naturwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Mathematisch Naturwissenschaftliche Reihe}, number = {884}, issn = {1866-8372}, doi = {10.25932/publishup-43511}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-435117}, pages = {1229 -- 1234}, year = {2016}, abstract = {Over the past ~40 years, several attempts were made to reintroduce Eurasian lynx to suitable habitat within their former distribution range in Western Europe. In general, limited numbers of individuals have been released to establish new populations. To evaluate the effects of reintroductions on the genetic status of lynx populations we used 12 microsatellite loci to study lynx populations in the Bohemian-Bavarian and Vosges-Palatinian forests. Compared with autochthonous lynx populations, these two reintroduced populations displayed reduced genetic diversity, particularly the Vosges-Palatinian population. Our genetic data provide further evidence to support the status of 'endangered' and 'critically endangered' for the Bohemian-Bavarian and Vosges-Palatinian populations, respectively. Regarding conservation management, we highlight the need to limit poaching, and advocate additional translocations to bolster genetic variability.}, language = {en} } @misc{ClusellaPolitiRosenblum2016, author = {Clusella, Pau and Politi, Antonio and Rosenblum, Michael}, title = {A minimal model of self-consistent partial synchrony}, series = {Postprints der Universit{\"a}t Potsdam : Mathematisch Naturwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Mathematisch Naturwissenschaftliche Reihe}, number = {890}, issn = {1866-8372}, doi = {10.25932/publishup-43626}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-436266}, pages = {19}, year = {2016}, abstract = {We show that self-consistent partial synchrony in globally coupled oscillatory ensembles is a general phenomenon.

Such a regime extends the notion of splay state from a uniform distribution of phases to an oscillating one. Suitable collective observables such as the Kuramoto order parameter allow detecting the presence of an inhomogeneous distribution. The characteristic and most peculiar property of self-consistent partial synchrony is the difference between the frequency of single units and that of the macroscopic field.}, language = {en} } @misc{PacholskiAgarwalBalderasValadez2016, author = {Pacholski, Claudia and Agarwal, Vivechana and Balderas-Valadez, Ruth Fabiola}, title = {Fabrication of porous silicon-based optical sensors using metal-assisted chemical etching}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-394426}, pages = {21430 -- 21434}, year = {2016}, abstract = {Optical biosensors based on porous silicon were fabricated by metal assisted chemical etching.

The event served as an introduction to a 13-day art exhibition and engaged in a re-evaluation of Eliot's poem after 9/11: while its first part emphasises the connection between Eliot's poem and Christian doctrine, its second part - especially the combination of poetry reading and musical performance - highlights the philosophical and spiritual dimensions of Four Quartets.}, language = {en} } @misc{vonReppertPuddellKocetal.2016, author = {von Reppert, Alexander and Puddell, J. and Koc, A. and Reinhardt, M. and Leitenberger, Wolfram and Dumesnil, K. and Zamponi, Flavio and Bargheer, Matias}, title = {Persistent nonequilibrium dynamics of the thermal energies in the spin and phonon systems of an antiferromagnet}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-98710}, pages = {11}, year = {2016}, abstract = {We present a temperature and fluence dependent Ultrafast X-Ray Diffraction study of a laser-heated antiferromagnetic dysprosium thin film.

We present results from two masked priming experiments investigating the processing of complex Japanese words written in less common (moraic) scripts. In Experiment 1, participants performed lexical decisions on target verbs; these were preceded by primes which were either (i) a past-tense form of the same verb, (ii) a stem-related form with the epenthetic vowel -i, (iii) a semantically-related form, and (iv) a phonologically-related form. Significant priming effects were obtained for prime types (i), (ii), and (iii), but not for (iv). This pattern of results differs from previous findings on languages with alphabetic scripts, which found reliable masked priming effects for morphologically related prime/target pairs of type (i), but not for non-affixal and semantically-related primes of types (ii), and (iii). In Experiment 2, we measured priming effects for prime/target pairs which are neither morphologically, semantically, phonologically nor - as presented in their moraic scripts—orthographically related, but which—in their commonly written form—share the same kanji, which are logograms adopted from Chinese. The results showed a significant priming effect, with faster lexical-decision times for kanji-related prime/target pairs relative to unrelated ones. We conclude that affix-stripping is insufficient to account for masked morphological priming effects across languages, but that language-particular properties (in the case of Japanese, the writing system) affect the processing of (morphologically) complex words.}, language = {en} } @misc{ZabelWinterKellingetal.2016, author = {Zabel, Andr{\´e} and Winter, Alette and Kelling, Alexandra and Schilde, Uwe and Strauch, Peter}, title = {Tetrabromidocuprates(II)-Synthesis, Structure and EPR}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-91470}, pages = {14}, year = {2016}, abstract = {Metal-containing ionic liquids (ILs) are of interest for a variety of technical applications, e.g., particle synthesis and materials with magnetic or thermochromic properties.

The sterically demanding cations were used to separate the paramagnetic Cu(II) ions for EPR measurements. The EPR hyperfine structure in the spectra of these new compounds is not resolved, due to the line broadening resulting from magnetic exchange between the still-incomplete separated paramagnetic Cu(II) centres. For the majority of compounds, the principal g values (g|| and gK) of the tensors could be determined and information on the structural changes in the [CuBr4]2- anions can be obtained.

Nevertheless, current theory mainly assumes distinct and time-invariant trait values. We examined the combined effects of the range and the speed of trait adaptation on species coexistence using an innovative multispecies predator-prey model. It allows for temporal trait changes of all predator and prey species and thus simultaneous coadaptation within and among trophic levels. We show that very small or slow trait adaptation did not facilitate coexistence because the stabilizing niche differences were not sufficient to offset the fitness differences. In contrast, sufficiently large and fast trait adaptation jointly promoted stable or neutrally stable species coexistence. Continuous trait adjustments in response to selection enabled a temporally variable convergence and divergence of species traits; that is, species became temporally more similar (neutral theory) or dissimilar (niche theory) depending on the selection pressure, resulting over time in a balance between niche differences stabilizing coexistence and fitness differences promoting competitive exclusion. Furthermore, coadaptation allowed prey and predator species to cluster into different functional groups. This equalized the fitness of similar species while maintaining sufficient niche differences among functionally different species delaying or preventing competitive exclusion. In contrast to previous studies, the emergent feedback between biomass and trait dynamics enabled supersaturated coexistence for a broad range of potential trait adaptation and parameters. We conclude that accounting for trait adaptation may explain stable and supersaturated species coexistence for a broad range of environmental conditions in natural systems when the absence of such adaptive changes would preclude it. Small trait changes, coincident with those that may occur within many natural populations, greatly enlarged the number of coexisting species.}, language = {en} } @misc{AntoniewiczBrand2016, author = {Antoniewicz, Franziska and Brand, Ralf}, title = {Dropping Out or Keeping Up?}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-97060}, pages = {8}, year = {2016}, abstract = {The aim of this study was to examine how automatic evaluations of exercising (AEE) varied according to adherence to an exercise program.

Attendance data were collected for all participants and used in a cluster analysis of adherence patterns. Three different adherence patterns (52 maintainers, 16 early dropouts, 20 late dropouts; 40.91\% overall dropouts) were detected using cluster analyses. Participants from these three clusters differed significantly with regard to their positive and negative associations to exercising before the first course meeting (η2p = 0.07). Discriminant function analyses revealed that positive associations to exercising was a particularly good discriminating factor. This is the first study to provide evidence of the differential impact of positive and negative associations on exercise behavior over the medium term. The findings contribute to theoretical understanding of evaluative processes from a dual-process perspective and may provide a basis for targeted interventions.}, language = {en} }
