In the most constrained version of the theory, all phonological processes should be thus reducible. This hypothesis is tested by alternations that appear to be phonological but in which universal markedness principles appear to play no role. If we are to pursue the claim that all phonological processes depend on the interaction of faithfulness and markedness, then processes that are not dependent on markedness must lie outside phonology. In this paper I will examine a group of such processes, the initial consonant mutations of the Celtic languages, and argue that they belong entirely to the morphology of the languages, not the phonology.}, language = {en} } @misc{tenFreyhausHuntgeburthWingeretal.2006, author = {ten Freyhaus, Henrik and Huntgeburth, Michael and Winger, Kirstin and B{\"a}umer, Anselm T. and Vantler, Marius and Bekhite, Mohamed M. and Wartenberg, Maria and Sauer, Heinrich and Sparwel, Jan and Rosenkranz, Stephan}, title = {Inhibition of ROS liberation attenuates PDGF-Dependent chemotaxis, but not proliferation in vascular smooth muscle cells - Critical role of Src kinase}, series = {Circulation : an American Heart Association journal}, volume = {114}, journal = {Circulation : an American Heart Association journal}, publisher = {Lippincott Williams \& Wilkins}, address = {Philadelphia}, issn = {0009-7322}, pages = {296 -- 297}, year = {2006}, language = {en} } @article{TorjekWituckaWallMeyeretal.2006, author = {Torjek, Otto and Witucka-Wall, Hanna and Meyer, Rhonda C. and von Korff, Maria and Kusterer, Barbara and Rautengarten, Carsten and Altmann, Thomas}, title = {Segregation distortion in Arabidopsis C24/Col-0 and Col-0/C24 recombinant inbred line populations is due to reduced fertility caused by epistatic interaction of two loci}, series = {Theoretical and applied genetics}, volume = {113}, journal = {Theoretical and applied genetics}, publisher = {Springer}, address = {Berlin}, issn = {0040-5752}, doi = {10.1007/s00122-006-0402-3}, pages = {1551 -- 1561}, year = {2006}, abstract = {A new large set of reciprocal recombinant inbred lines (RILs) was created between the Arabidopsis accessions Col-0 and C24 for quantitative trait mapping approaches, consisting of 209 Col-0 x C24 and 214 C24 x Col-0 F-7 RI lines. Genotyping was performed using 110 evenly distributed framework single nucleotide polymorphism markers, yielding a genetic map of 425.70 cM, with an average interval of 3.87 cM. Segregation distortion (SD) was observed in several genomic regions during the construction of the genetic map. Linkage disequilibrium analysis revealed an association between a distorted region at the bottom of chromosome V and a non-distorted region on chromosome IV. A detailed analysis of the RILs for these two regions showed that an SD occurred when homozygous Col-0 alleles on chromosome IV coincided with homozygous C24 alleles at the bottom of chromosome V. Using nearly isogenic lines segregating for the distorted region we confirmed that this genotypic composition leads to reduced fertility and fitness.}, language = {en} } @article{HobbhahnKuechmeisterPorembski2006, author = {Hobbhahn, Nina and K{\"u}chmeister, Heike and Porembski, Stefan}, title = {Pollination biology of mass flowering terrestrial Utricularia species (Lentibulariaceae) in the Indian Western Ghats}, series = {Plant biology}, volume = {8}, journal = {Plant biology}, number = {6}, publisher = {Wiley-Blackwell}, address = {Oxford}, issn = {1435-8603}, doi = {10.1055/s-2006-924566}, pages = {791 -- 804}, year = {2006}, abstract = {The pollination biology of three mass flowering Utricularia species of the Indian Western Ghats, U. albocaerulea, U. purpurascens, and U. reticulata, was studied for the first time by extensive observation of flower visitors, pollination experiments, and nectar analyses. The ephemerality of the Utricularia habitats on lateritic plateaus, weather conditions adverse to insects, lack of observations of flower visitors to other Utricularia spp., and the predominance of at least. facultative autogamy in the few Utricularia species studied so far suggested that an autogamous breeding system is the common case in the genus. In contrast, we showed that the studied populations are incapable of autonomous selfing, or that it is an event of negligible rarity, although P/O was similarily low as in autogamous species investigated by other authors. In all three species the spatial arrangement of the reproductive organs makes an insect vector necessary for pollen transfer between and within flowers. However, U. purpurascens and U. reticulata are highly self-compatible, which allows for visitor-mediated auto-selfing and geitonogamy on inflorescence and clone level. Floral nectar is present in extremely small volumes in all three species, but sugar concentrations are high. More than 50 species of bees, butterflies, moths, hawk moths, and clipterans were observed to visit the flowers, and flower morphology facilitated pollination by all observed visitors. The results are discussed in the context of the phenological characteristics of the studied species, especially the phenomenon of mass flowering, and the environmental conditions of their habitats.}, language = {en} } @article{MontbrioPazoSchmidt2006, author = {Montbrio, Ernest and Pazo, Diego and Schmidt, J{\"u}rgen}, title = {Time delay in the Kuramoto model with bimodal frequency distribution}, series = {Physical review : E, Statistical, nonlinear and soft matter physics}, volume = {74}, journal = {Physical review : E, Statistical, nonlinear and soft matter physics}, publisher = {APS}, address = {College Park}, issn = {1539-3755}, doi = {10.1103/PhysRevE.74.056201}, pages = {5}, year = {2006}, abstract = {We investigate the effects of a time-delayed all-to-all coupling scheme in a large population of oscillators with natural frequencies following a bimodal distribution.

Theoretical analysis of genomic sequences suggested that the expression of these overlapping ORFs is facilitated by the use of alternate first exons leading to alternative transcripts. Here, we confirm the existence of these overlapping transcripts experimentally. Further, we identified a deletion in a molybdenum cofactor deficient patient, which removes the start codon for the small subunit (MOCS2A). We observed undisturbed production of both transcripts, while Western blot analysis demonstrated that MOCS2B, the large subunit, is unstable in the absence of MOCS2A.

Comparison of observed garnet zonation patterns with thermodynamically modelled patterns shows that the different patterns are caused by differences in the water content of the subducted protoliths during prograde metamorphism. Zonation patterns of garnets in water-saturated host rocks show typical prograde chemical zonations with steadily increasing pyrope content and increasing XMg, together with bell-shaped spessartine patterns. In contrast, garnets in water-undersaturated rocks have more complex zonation patterns with a characteristic decrease in pyrope and XMg between core and inner rim. In some cases, garnets show an abrupt compositional change in core-to-rim profiles, possibly due to water-undersaturation prior to HP metamorphism. Garnets from both water-saturated and water-undersaturated rocks show signs of intervening growth interruptions and core resorption. This growth interruption results from bulk-rock depletion caused by fractional garnet crystallization. The water content during burial influences significantly the physical properties of the subducted rocks. Due to enhanced garnet crystallization, water-undersaturated rocks, i.e. those lacking a free fluid phase, become denser than their water-saturated equivalents, facilitating the subduction of continental material. Although water-bearing phases such as phengite and epidote are stable up to eclogite-facies conditions in these rocks, dehydration reactions during subduction are lacking in water-undersaturated rocks up to the transition to the eclogite facies, due to the thermodynamic stability of such hydrous phases at high P-T conditions. Our calculations show that garnet zonation patterns strongly depend on the mineral parageneses stable during garnet growth and that certain co-genetic mineral assemblages cause distinct garnet zonation patterns. This observation enables interpretation of complex garnet growth zonation patterns in terms of garnet-forming reactions and water content during HP metamorphism, as well determination of detailed P-T paths.}, language = {en} } @article{RauschmannHuggenbergerKossatzetal.2006, author = {Rauschmann, Michael A. and Huggenberger, Stefan and Kossatz, Lars Swen and Oelschl{\"a}ger, Helmut H.

Comparison of these anatomical methods reveals that for a complete structural analysis, a combination of modern imaging techniques and conventional morphological methods is needed. In addition to the perinatal dolphins, we include series of microslides of fetal odontocetes (S. attenuata, common dolphin Delphinus delphis, narwhal Monodon monoceros). In contrast to other mammals, newborn cetaceans represent an extremely precocial state of development correlated to the fact that they have to swim and surface immediately after birth. Accordingly, the morphology of the perinatal dolphin head is very similar to that of the adult. Comparison with early fetal stages of dolphins shows that the ontogenetic change from the general mammalian bauplan to cetacean organization was characterized by profound morphological transformations of the relevant organ systems and roughly seems to parallel the phylogenetic transition. from terrestrial ancestors to modern odontocetes.}, language = {en} } @article{HoieSjoholmGuldstrandetal.2006, author = {Hoie, Lars H. and Sjoholm, Ake and Guldstrand, Marie and Zunft, Hans-Joachim Franz and Lueder, Wolfgang and Graubaum, Hans-Joachim and Gr{\"u}nwald, J{\"o}rg}, title = {Ultra heat treatment destroys cholesterol-lowering effect of soy protein}, series = {International journal of food sciences and nutrition}, volume = {57}, journal = {International journal of food sciences and nutrition}, publisher = {Taylor \& Francis}, address = {Abingdon}, issn = {0963-7486}, doi = {10.1080/09637480601009059}, pages = {512 -- 519}, year = {2006}, abstract = {A randomized, placebo-controlled, double-blind clinical study was performed to investigate the dose-dependent response of serum cholesterol after consuming an ultra-heat-treated milk containing a soy protein preparation.
