Here, we present isothermal hydrodynamic simulations of moonlet-induced propellers in Saturn's A ring that denote a further development of the original model. We find excellent agreement between these new hydrodynamic and corresponding N-body simulations. Furthermore, the hydrodynamic simulations confirm the predicted scaling laws and the analytical solution for the density in the propeller gaps. Finally, this mean field approach allows us to simulate the pattern of the giant propeller Bl{\´e}riot, which is too large to be modeled by direct N-body simulations. Our results are compared to two stellar occultation observations by the Cassini Ultraviolet Imaging Spectrometer (UVIS), which intersect the propeller Bl{\´e}riot. Best fits to the UVIS optical depth profiles are achieved for a Hill radius of 590 m, which implies a moonlet diameter of about 860 m. Furthermore, the model favors a kinematic shear viscosity of the surrounding ring material of ν0 = 340 cm2 s-1, a dispersion velocity in the range of 0.3 cm s-1 < c0 < 1.5 cm s-1, and a fairly high bulk viscosity 7 < ξ0/ν0 < 17. These large transport values might be overestimated by our isothermal ring model and should be reviewed by an extended model including thermal fluctuations.}, language = {en} } @article{PourteauSchererSchornetal.2019, author = {Pourteau, Amaury and Scherer, Erik E. and Schorn, Simon and Bast, Rebecca and Schmidt, Alexander and Ebert, Lisa}, title = {Thermal evolution of an ancient subduction interface revealed by Lu-Hf garnet geochronology, Halilbagi Complex (Anatolia)}, series = {Geoscience Frontiers}, volume = {10}, journal = {Geoscience Frontiers}, number = {1}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1674-9871}, doi = {10.1016/j.gsf.2018.03.004}, pages = {127 -- 148}, year = {2019}, abstract = {The thermal structure of subduction zones exerts a major influence on deep-seated mechanical and chemical processes controlling arc magmatism, seismicity, and global element cycles. Accretionary complexes exposed inland may comprise tectonic blocks with contrasting pressure-temperature (P-T) histories, making it possible to investigate the dynamics and thermal evolution of former subduction interfaces. With this aim, we present new Lu-Hf geochronological results for mafic rocks of the Halilbagi Complex (Anatolia) that evolved along different thermal gradients. Samples include a lawsonite-epidote blueschist, a lawsonite-epidote eclogite, and an epidote eclogite (all with counter-clockwise P-T paths), a prograde lawsonite blueschist with a "hairpin"-type P-T path, and a garnet amphibolite from the overlying sub-ophiolitic metamorphic sole. Equilibrium phase diagrams suggest that the garnet amphibolite formed at similar to 0.6-0.7 GPa and 800-850 degrees C, whereas the prograde lawsonite blueschist records burial from 2.1 GPa and 420 degrees C to 2.6 GPa and 520 degrees C. Well-defined Lu-Hf isochrons were obtained for the epidote eclogite (92.38 +/- 0.22 Ma) and the lawsonite-epidote blueschist (90.19 +/- 0.54 Ma), suggesting rapid garnet growth. The lawsonite-epidote eclogite (87.30 +/- 0.39 Ma) and the prograde lawsonite blueschist (ca. 86 Ma) are younger, whereas the garnet amphibolite (104.5 +/- 3.5 Ma) is older. Our data reveal a consistent trend of progressively decreasing geothermal gradient from granulite-facies conditions at similar to 104 Ma to the epidote-eclogite facies around 92 Ma, and the lawsonite blueschist-facies between 90 Ma and 86 Ma. Three Lu-Hf garnet dates (between 92 Ma and 87 Ma) weighted toward the growth of post-peak rims (as indicated by Lu distribution in garnet) suggest that the HP/LT rocks were exhumed continuously and not episodically. We infer that HP/LT metamorphic rocks within the Halilbagi Complex were subjected to continuous return flow, with "warm" rocks being exhumed during the tectonic burial of "cold" ones. Our results, combined with regional geological constraints, allow us to speculate that subduction started at a transform fault near a mid-oceanic spreading centre. Following its formation, this ancient subduction interface evolved thermally over more than 15 Myr, most likely as a result of heat dissipation rather than crustal underplating.

In the case of cyanobacteria, phages can reduce primary production and infected hosts release intracellular nutrients influencing planktonic food web structure, community dynamics, and biogeochemical cycles. Cyanophages may be of great importance in aquatic food webs during large cyanobacterial blooms unless the host population becomes resistant to phage infection. The consequences on plankton community dynamics of the evolution of phage resistance in bloom forming cyanobacterial populations are still poorly studied. Here, we examined the effect of different frequencies of a phage-resistant genotype within a filamentous nitrogen-fixing Nodularia spumigena population on an experimental plankton community. Three Nodularia populations with different initial frequencies (0\%, 5\%, and 50\%) of phage-resistant genotypes were inoculated in separate treatments with the phage 2AV2, the green alga Chlorella vulgaris, and the rotifer Brachionus plicatilis, which formed the experimental plankton community subjected to either nitrogen-limited or nitrogen-rich conditions. We found that the frequency of the phage-resistant Nodularia genotype determined experimental community dynamics. Cyanobacterial populations with a high frequency (50\%) of the phage-resistant genotype dominated the cultures despite the presence of phages, retaining most of the intracellular nitrogen in the plankton community. In contrast, populations with low frequencies (0\% and 5\%) of the phage-resistant genotype were lysed and reduced to extinction by the phage, transferring the intracellular nitrogen held by Nodularia to Chlorella and rotifers, and allowing Chlorella to dominate the communities and rotifers to survive.

It has been suggested that anoxic conditions in shallow marine environments, linked to the end-Permian mass extinction, limited mat-inhibiting metazoans allowing for this microbialite expansion. The presence of a diverse suite of proxies indicating oxygenated shallow sea-water conditions (metazoan fossils, biomarkers and redox proxies) from microbialite successions have, however, challenged the inference of anoxic conditions. Here, the distribution and faunal composition of Griesbachian microbialites from China, Iran, Turkey, Armenia, Slovenia and Hungary are investigated to determine the factors that allowed microbialite-forming microbial mats to flourish following the end-Permian crisis. The results presented here show that Neotethyan microbial buildups record a unique faunal association due to the presence of keratose sponges, while the Palaeotethyan buildups have a higher proportion of molluscs and the foraminifera Earlandia. The distribution of the faunal components within the microbial fabrics suggests that, except for the keratose sponges and some microconchids, most of the metazoans were transported into the microbial framework via wave currents. The presence of both microbialites and metazoan associations were limited to oxygenated settings, suggesting that a factor other than anoxia resulted in a relaxation of ecological constraints following the mass extinction event. It is inferred that the end-Permian mass extinction event decreased the diversity and abundance of metazoans to the point of significantly reducing competition, allowing photosynthesis-based microbial mats to flourish in shallow water settings and resulting in the formation of widespread microbialites.}, language = {en} } @article{BarthGeertsemaBevingtonetal.2019, author = {Barth, Sophia and Geertsema, Marten and Bevington, Alexandre R. and Bird, Alison L. and Clague, John J. and Millard, Tom and Bobrowsky, Peter T. and Hasler, Andreas and Liu, Hongjiang}, title = {Landslide response to the 27 October 2012 earthquake (M-W 7.8), southern Haida Gwaii, British Columbia, Canada}, series = {Landslides : journal of the International Consortium on Landslides, ICL}, volume = {17}, journal = {Landslides : journal of the International Consortium on Landslides, ICL}, number = {3}, publisher = {Springer}, address = {Heidelberg}, issn = {1612-510X}, doi = {10.1007/s10346-019-01292-7}, pages = {517 -- 526}, year = {2019}, abstract = {In this paper, we examine the influence of the 27 October 2012, M-w 7.8 earthquake on landslide occurrence in the southern half of Haida Gwaii (formerly Queen Charlotte Islands), British Columbia, Canada. Our 1350 km(2) study area is undisturbed, primarily forested terrain that has not experienced road building or timber harvesting. Our inventory of landslide polygons is based on optical airborne and spaceborne images acquired between 2007 and 2018, from which we extracted and mapped 446 individual landslides (an average of 33 landslides per 100 km(2)). The landslide rate in years without major earthquakes averages 19.4 per year, or 1.4/100 km(2)/year, and the annual average area covered by non-seismically triggered landslides is 35 ha/year. The number of landslides identified in imagery closely following the 2012 earthquake, and probably triggered by it, is 244 or an average of about 18 landslides per 100 km(2). These landslides cover a total area of 461 ha. In the following years-2013-2016 and 2016-2018-the number of landslides fell, respectively, to 26 and 13.5 landslides per year. In non-earthquake years, most landslides happen on south-facing slopes, facing the prevailing winds. In contrast, during or immediately after the earthquake, up to 32\% of the landslides occurred on north and northwest-facing slopes.

Evidence This view is supported by palaeoecological and environmental evidence. Once established, Asian larch forests are likely to have stabilized through a complex vegetation-fire-permafrost soil-climate feedback system. Conclusion With respect to future forest developments, this implies that Asian larch forests are likely to be governed by long-term trajectories and are therefore largely resistant to natural climate variability on time-scales shorter than millennia.

Multiple regression analyses revealed that performance in the acquisition of the PAL task was significantly associated with phonological awareness and backward recall, whereas performance in the retrieval of the PAL task was significantly associated with rapid automatized naming, phonological awareness, and backward recall. Moreover, PAL proved to be mediating the relation between reading precursors and letter knowledge.

At constant temperature, Raman peak position, including the more intense CO2 peak (nu+), decreases (shifts to lower wave number) with increasing pressure for all three gases over the entire pressure and temperature (PT) range studied. At constant pressure, the peak position for CO2 and CH4 increases (shifts to higher wave number) with increasing temperature over the entire PT range studied. In contrast, N-2 first shows an increase in peak position with increasing temperature at constant pressure, followed by a decrease in peak position with increasing temperature. The inflection temperature at which the trend reverses for N-2 is located between 0 degrees C and 50 degrees C at pressures above similar to 50 bars and is pressure dependent. Below similar to 50 bars, the inflection temperature was observed as low as -120 degrees C. The shifts in Raman peak positions with PT are related to relative density changes, which reflect changes in intermolecular attraction and repulsion. A conceptual model relating the Raman spectral properties of N-2, CO2, and CH4 to relative density (volume) changes and attractive and repulsive forces is presented here. Additionally, reduced temperature-dependent densimeters and barometers are presented for each pure component over the respective PT ranges.

This review will look at whether that is indeed the case. Social-science handbooks naturally are very broad. This also applies to the particular handbook under review. It comprises six content-thematic parts with 33 chapters by 73 authors from 21 countries, with the UK and USA dominant. The focal points, discussed in more detail below, are local elections and local governance, local governments in different jurisdictions, the challenges of local government services, citizen engagement in local affairs, and local authorities in multi-level finance systems that shape how municipal governments 'get and spend' public money. These are exactly the topics actually discussed in the international community of political scientists. As a preliminary, the editors work out the theoretical-methodological foundations of the topic. They define 'the local' as 'geographically defined sub-national state administrative or political divisions' (p. 3). As next steps, they analyse the difference between government and governance, and investigate whether local government is globally important and relevant. Fortunately, they conclude that this is indeed the case. Part I of the handbook illustrates 'substantive variations' in the local electoral systems and 'notable divergences in the values and assumptions of local governance among democratic countries' (p. 23). That topic is indeed central to local authorities' legitimacy in democratic political systems. The focus of this part of the handbook is on current research and debates around local electoral systems, the challenges of local political leadership and the councillor's role in modern local policy. Current trends at the local level are analysed from the actors' perspectives or from an economic point of view by comparing institutionalised differences in city managers, mayors and council members across different jurisdictions. Sections that investigate traditional leadership and local government in Pacific Island countries are of particular interest to most Western readers, because in Europe and North America we know too little about such issues in that part of the world. Part II of the handbook presents current development processes and challenges in various local government systems. The chapters are territorially oriented around nation states or sub-national regions. This part of the handbook deal with local government in the Pacific Islands, Latin America, and New Zealand and in the Caribbean. However, the rationale behind country selection is not always clear; important countries like China, India and Nigeria, just to name a few, are absent. Unfortunately, there is no summary article highlighting similarities and differences, as well as the challenges in local government, relating to the countries studied in the book. The development of local services is the focus of Part III of the handbook, however, the definition of local services remains highly controversial and their scope varies widely between the countries. From the 1980s onwards, there was a long-term trend towards the marketisation and economisation of local politics, but since the turn of the millennium, there has been a counter-trend of the return of municipalities and third sector in the fields of local public services (Wollmann 2018). The book analyses the US and Georgia as case studies for development trends, finding that local government entrepreneurship remains an important factor in promoting economic development and strengthening capacities. I was pleased to see that Part IV, the next and most extensive part of the handbook, deals with citizen engagement, because the future of local self-government across the world depends not only on top down activities by local governing elites, but above all on the commitment of the inhabitants of cities and municipalities. Practices and challenges of citizen participation in local government are analysed in inspiring case studies of mid-sized cities in Russia and the United States. The contribution on urban governance of austerity in Europe is also of particular interest. The 2008 global financial crash and the subsequent severe budgetary pressure on municipalities in many countries was a key event in the history and development of local self-government, confronting municipalities with 'the harsh realities of political economy' (p. 293). Several articles analyse the causes of the declining confidence of the citizens in local authorities in some countries. In contrast, the open budget tool in Brazil is as a positive example of collaborative stakeholder engagement. Part V deals with multi-level governance. With the exception of Australia, it is all about Europe, especially the role of municipalities in the EU's multilevel system. The authors conclude that 'local authorities are essential for executing EU legislation, and this turn allows them to shape EU policies' (p. 401). This part of the handbook includes the issue of local territorial reforms, which are central to local autonomy, combined with analyses of redesigning regional government and local-level Europeanisation. Subsequently, by comparing the local government systems of Southern Europe (France, Italy, Portugal and Spain), the authors underline convincingly the role of traditions, identity, legal frameworks and institutions in local government. Part VI of the book deals with the financial dimension of local self-government under the heading 'Getting and spending'. This is indeed the 'key source of dispute between local and central government' (p. 467) and the crucial factor shaping true local autonomy. Meritoriously, this part also contains a chapter on the fight against corruption and unethical behaviour by public servants. Based on research linking corruption to transparency and accountability, two case studies describe how Tbilisi (Georgia) and Lviv (Ukraine) try to reduce corruption in government budgeting and procurement. Enhancing Value-For-Money audit in local government highlights another important side of local finance. An interesting comparison reveals significant differences in local government revenues in European Union member states between 2000 and 2014. Of course, even in a 530-page book, some important aspects remain underexposed. Above all, I would have liked more attention on some of the enormous future challenges facing democratic systems and with them local governments all over the world, such as digitisation (e.g. in smart cities), the integration of migrants or climate change. The international networking of municipalities should also be given greater prominence. To sum it up, The Routledge Handbook on International Local Government is indeed 'ambitiously titled' as the editors underline. Yet, despite my critical objections about its focus on current issues rather than future challenges, they largely fulfil this promise and their general approach has worked well. Across continents and political-administrative cultures, illustrated with many new research findings, they have created an outstanding publication focusing on the challenges and policy of local self-governmental authorities and other local stakeholders. There is a good chance that this handbook will belong in future to the social science standard works on local issues, and be included in academic political science teaching. May the publisher's wish come true; that this book stimulates its readers to develop further research ideas. Finally, I come back to my initial question.

We evaluate the sediment flux response to the Maule earthquake in the Chilean Andes (Mw 8.8) using daily suspended sediment records from 31 river gauges. The catchments cover drainage areas of 350 to around 10,000 km(2), including a wide range of topographic slopes and vegetation cover of the Andean western flank. We compare the 3- to 8-year postseismic record of sediment flux to each of the following preseismic periods: (1) all preseismic data, (2) a 3-year period prior to the seismic event, and (3) the driest preseismic periods, as drought conditions prevailed in the postseismic period. Following the earthquake, no increases in suspended sediment flux were observed for moderate to high percentiles of the streamflow distribution (mean, median, and >= 75th percentile). However, more than half of the examined stations showed increased sediment flux during baseflow. By using a Random Forest approach, we evaluate the contributions of seismic intensities, peak ground accelerations, co-seismic landslides, hydroclimatic conditions, topography, lithology, and land cover to explain the observed changes in suspended sediment concentration and fluxes. We find that the best predictors are hillslope gradient, low-vegetation cover, and changes in streamflow discharge. This finding suggests a combined first-order control of topography, land cover, and hydrology on the catchment-wide erosion response. We infer a reduced sediment connectivity due to the postseismic drought, which increased the residence time of sediment detached and remobilized following the Maule earthquake.}, language = {en} } @article{GerstenbergLindholm2019, author = {Gerstenberg, Annette and Lindholm, Camilla}, title = {Language and aging research}, series = {Linguistics vanguard}, volume = {5}, journal = {Linguistics vanguard}, number = {s2}, publisher = {De Gruyter}, address = {Berlin}, issn = {2199-174X}, doi = {10.1515/lingvan-2019-0025}, pages = {6}, year = {2019}, abstract = {Our introduction to the special collection gives an overview of the research projects which were originally presented at the third CLARe network conference.

Reliability of streamflow data requires a temporal continuity and a maintenance of the gauging stations, which data are affected by epistemic and random sources of error. An assessment of discharge meterings' and stage-discharge rating curves' uncertainties were carried out by comparing the accuracy of the measuring instruments of two different hydrometric networks (i.e., one analogical and one digital) established in the same river location at the Mediterranean island of Mallorca. Furthermore, the effects of such uncertainties were assessed on the hydrological dynamics, considering the significant global change impacts beset this island. Evaluation was developed at four representative gauging stations of the hydrographic network with analogic (≈40 years) and digital (≈10 years) data series. The study revealed that the largest source of uncertainty in the analogical (28 to 274\%) and in the digital (17-37\%) networks were the stage-discharge rating curves. Their impact on the water resources was also evaluated at the event and annual scales, resulting in an average difference of water yields of 183\% and 142\% respectively. Such improvement on the comprehension of hydrometric networks uncertainties will dramatically benefit the interpretation of the long-term streamflow by providing better insights into the hydrologic and flood hazard planning, management and modelling.}, language = {en} } @article{WolfGuehr2019, author = {Wolf, Thomas and G{\"u}hr, Markus}, title = {Photochemical pathways in nucleobases measured with an X-ray FEL}, series = {Philosophical Transactions of the Royal Society of London, Series A : Mathematical, Physical and Engineering Sciences}, volume = {377}, journal = {Philosophical Transactions of the Royal Society of London, Series A : Mathematical, Physical and Engineering Sciences}, number = {2145}, publisher = {Royal Society}, address = {London}, issn = {1364-503X}, doi = {10.1098/rsta.2017.0473}, pages = {12}, year = {2019}, abstract = {The conversion of light energy into other molecular energetic degrees of freedom is often dominated by ultrafast, non-adiabatic processes. Femtosecond spectroscopy with optical pulses has helped in shaping our understanding of crucial processes in molecular energy-conversion. The advent of new, ultrashort and bright X-ray free electron laser sources opens the possibility to use X-ray-typical element and site sensitivity for ultrafast molecular research. We present two types of spectroscopy, ultrafast Auger and ultrafast X-ray absorption spectroscopy, and discuss their sensitivity to molecular processes. While Auger spectroscopy is able to monitor bond distance changes in the vicinity of an X-ray created core hole, near-edge absorption spectroscopy can deliver high-fidelity information on non-adiabatic transitions involving lone-pair orbitals. We demonstrate these features on the example of the UV-excited nucleobase thymine, investigated at the oxygen K-edge. We find a C-O bond elongation in the Auger data in addition to pi pi*/n pi* non-adiabatic transition in X-ray near-edge absorption. We compare the results from both methods and draw a conclusive scenario of non-adiabatic molecular relaxation after UV excitation.}, language = {en} } @article{KocSimovichSchoenemannetal.2019, author = {Koc, Julian and Simovich, Tomer and Sch{\"o}nemann, Eric and Chilkoti, Ashutosh and Gardner, Harrison and Swain, Geoffrey W. and Hunsucker, Kelli and Laschewsky, Andr{\´e} and Rosenhahn, Axel}, title = {Sediment challenge to promising ultra-low fouling hydrophilic surfaces in the marine environment}, series = {Biofouling : the journal of bioadhesion and biofilm research}, volume = {35}, journal = {Biofouling : the journal of bioadhesion and biofilm research}, number = {4}, publisher = {Taylor \& Francis}, address = {London}, issn = {0892-7014}, doi = {10.1080/08927014.2019.1611790}, pages = {454 -- 462}, year = {2019}, abstract = {Hydrophilic coatings exhibit ultra-low fouling properties in numerous laboratory experiments. In stark contrast, the antifouling effect of such coatings in vitro failed when performing field tests in the marine environment. The fouling release performance of nonionic and zwitterionic hydrophilic polymers was substantially reduced compared to the controlled laboratory environment. Microscopy and spectroscopy revealed that a large proportion of the accumulated material in field tests contains inorganic compounds and diatomaceous soil. Diatoms adhered to the accumulated material on the coating, but not to the pristine polymer. Simulating field tests in the laboratory using sediment samples collected from the test sites showed that incorporated sand and diatomaceous earth impairs the fouling release characteristics of the coatings. When exposed to marine sediment from multiple locations, particulate matter accumulated on these coatings and served as attachment points for diatom adhesion and enhanced fouling. Future developments of hydrophilic coatings should consider accumulated sediment and its potential impact on the antifouling performance.}, language = {en} }
