The AlpArray Seismic Network has been deployed with contributions from 36 institutions from 11 countries to map physical properties of the lithosphere and asthenosphere in 3D and thus to obtain new, high-resolution geophysical images of structures from the surface down to the base of the mantle transition zone. With over 600 broadband stations operated for 2 years, this seismic experiment is one of the largest simultaneously operated seismological networks in the academic domain, employing hexagonal coverage with station spacing at less than 52 km. This dense and regularly spaced experiment is made possible by the coordinated coeval deployment of temporary stations from numerous national pools, including ocean-bottom seismometers, which were funded by different national agencies. They combine with permanent networks, which also required the cooperation of many different operators. Together these stations ultimately fill coverage gaps. Following a short overview of previous large-scale seismological experiments in the Alpine region, we here present the goals, construction, deployment, characteristics and data management of the AlpArray Seismic Network, which will provide data that is expected to be unprecedented in quality to image the complex Alpine mountains at depth.}, language = {en} } @misc{FischerRaederWewetzeretal.2004, author = {Fischer, Florian and R{\"a}der, Andy and Wewetzer, Gudrun and Hempel, Luisa and Sack, Beate and Schwill, Andreas and Surrey, Heike and Claussen, Martin and Klein, Oliver and Czempinski, Katrin and K{\"u}chmeister, Heike and Gonz{\´a}lez, Antonio Mart{\´i}nez and Pecher, Klaus and Resch-Esser, Ursula and Gommert, Natalie}, title = {Portal = Unbekanntes Terrain: Die EU-Erweiterung birgt neue M{\"o}glichkeiten}, number = {06-08/2004}, organization = {Universit{\"a}t Potsdam, Referat f{\"u}r Presse- und {\"O}ffentlichkeitsarbeit}, issn = {1618-6893}, doi = {10.25932/publishup-43980}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-439806}, pages = {51}, year = {2004}, abstract = {Aus dem Inhalt: - Unbekanntes Terrain: Die EU-Erweiterung birgt neue M{\"o}glichkeiten - Zehn Jahre MenschenRechtsZentrum - Wassermangel im Nahen Osten - Karl-Scheel-Preis f{\"u}r Turbulenzforschung}, language = {de} } @article{FischerKeller2021, author = {Fischer, Florian and Keller, Matthias}, title = {Riesz decompositions for Schr{\"o}dinger operators on graphs}, series = {Journal of mathematical analysis and applications}, volume = {495}, journal = {Journal of mathematical analysis and applications}, number = {1}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0022-247X}, doi = {10.1016/j.jmaa.2020.124674}, pages = {22}, year = {2021}, abstract = {We study superharmonic functions for Schrodinger operators on general weighted graphs.

Along continuous forest-savanna transects in the Comoe National Park, the change in the amount and composition of non-woody phytomass was investigated from savanna to forest interior. This was correlated with the cover of vegetation strata above, soil depth, and the occurrence of seasonal surface fires. Phytomass mainly consisted of leaf litter in the forests (about 400 g m(-2) at the end of the rainy season, and about 600 g m(-2) at the end of the dry season) and of grasses in the savanna (about 900 g m(-2)). Low grass biomass appeared to be primarily the result of suppression by competing woody species and not of shallow soil. The occurrence of early dry-season fires seemed to be determined mainly by the amount of grass biomass as fuel because fires occurred in almost all savanna plots while forest sites remained unaffected. However, late dry-season fires will encounter higher amounts of leaf litter raising fire probability in forests. Due to the importance of the amount of combustible phytomass, fire probability and intensity might increase with annual precipitation in both savanna and forest}, language = {en} } @article{ZaldenQuirinSchumacheretal.2019, author = {Zalden, Peter and Quirin, Florian and Schumacher, Mathias and Siegel, Jan and Wei, Shuai and Koc, Azize and Nicoul, Matthieu and Trigo, Mariano and Andreasson, Pererik and Enquist, Henrik and Shu, Michael J. and Pardini, Tommaso and Chollet, Matthieu and Zhu, Diling and Lemke, Henrik and Ronneberger, Ider and Larsson, J{\"o}rgen and Lindenberg, Aaron M. and Fischer, Henry E. and Hau-Riege, Stefan and Reis, David A. and Mazzarello, Riccardo and Wuttig, Matthias and Sokolowski-Tinten, Klaus}, title = {Femtosecond x-ray diffraction reveals a liquid-liquid phase transition in phase-change materials}, series = {Science}, volume = {364}, journal = {Science}, number = {6445}, publisher = {American Assoc. for the Advancement of Science}, address = {Washington, DC}, issn = {0036-8075}, doi = {10.1126/science.aaw1773}, pages = {1062 -- 1067}, year = {2019}, abstract = {In phase-change memory devices, a material is cycled between glassy and crystalline states.

Using femtosecond x-ray diffraction and ab initio computer simulations, we determined the time-dependent pair-correlation function of phase-change materials throughout the melt-quenching and crystallization process. We found a liquid-liquid phase transition in the phase-change materials Ag4In3Sb67Te26 and Ge15Sb85 at 660 and 610 kelvin, respectively. The transition is predominantly caused by the onset of Peierls distortions, the amplitude of which correlates with an increase of the apparent activation energy of diffusivity.

It participates in the regulation of renal tubular phosphate reabsorption and stimulates renal tubular Ca2+ reabsorption. Klotho hypomorphic mice (klotho(hm)) suffer from severe growth deficit, rapid aging, and early death, events largely reversed by a vitamin D-deficient diet. The present study explored the role of Klotho deficiency in mineral and electrolyte metabolism. To this end, klothohm mice and wild-type mice (klotho(+/+)) were subjected to a normal (D+) or vitamin D-deficient (D-) diet or to a vitamin D-deficient diet for 4 wk and then to a normal diet (D-/+). At the age of 8 wk, body weight was significantly lower in klotho(hm)D(+) mice than in klotho(+/ +)D(+) mice, klotho(hm)D(-) mice, and klotho(hm)D(-/+) mice. Plasma concentrations of 1,25(OH)(2)D-3, adrenocorticotropic hormone (ACTH), antidiuretic hormone (ADH), and aldosterone were significantly higher in klotho(hm)D(+) mice than in klotho(+/+)D(+) mice. Plasma volume was significantly smaller in klotho(hm)D(-/+) mice, and plasma urea, Ca2+, phosphate and Na+, but not K+ concentrations were significantly higher in klotho(hm)D(+) mice than in klotho(+/+)D(+) mice. The differences were partially abrogated by a vitamin D-deficient diet. Moreover, the hyperaldosteronism was partially reversed by Ca2+-deficient diet. Ussing chamber experiments revealed a marked increase in amiloride-sensitive current across the colonic epithelium, pointing to enhanced epithelial sodium channel (ENaC) activity. A salt-deficient diet tended to decrease and a salt-rich diet significantly increased the life span of klotho(hm)D(+) mice. In conclusion, the present observation disclose that the excessive formation of 1,25(OH)(2)D-3 in Klotho-deficient mice results in extracellular volume depletion, which significantly contributes to the shortening of life span.}, language = {en} } @article{PfestorfWeissMuelleretal.2013, author = {Pfestorf, H. and Weiss, L. and M{\"u}ller, J. and Boch, Steffen and Socher, S.

Amount and intensity of these changes challenge current monitoring frameworks typically based on classic indicators such as selected target species or diversity indices. Indicators based on plant functional traits provide an interesting extension since they reflect ecological strategies at individual and ecological processes at community levels. They typically show convergent responses to gradients of land-use intensity over scales and regions, are more directly related to environmental drivers than diversity components themselves and enable detecting directional changes in whole community dynamics. However, probably due to their labor- and cost intensive assessment in the field, they have been rarely applied as indicators so far. Here we suggest overcoming these limitations by calculating indicators with plant traits derived from online accessible databases. Aiming to provide a minimal trait set to monitor effects of land-use intensification on plant diversity we investigated relationships between 12 community mean traits, 2 diversity indices and 6 predictors of land-use intensity within grassland communities of 3 different regions in Germany (part of the German 'Biodiversity Exploratory' research network). By standardization of traits and diversity measures, use of null models and linear mixed models we confirmed (i) strong links between functional community composition and plant diversity, (ii) that traits are closely related to land-use intensity, and (iii) that functional indicators are equally, or even more sensitive to land-use intensity than traditional diversity indices. The deduced trait set consisted of 5 traits, i.e., specific leaf area (SLA), leaf dry matter content (LDMC), seed release height, leaf distribution, and onset of flowering. These database derived traits enable the early detection of changes in community structure indicative for future diversity loss. As an addition to current monitoring measures they allow to better link environmental drivers to processes controlling community dynamics.}, language = {en} } @article{WeissPfestorfMayetal.2014, author = {Weiss, Lina and Pfestorf, Hans and May, Felix and K{\"o}rner, Katrin and Boch, Steffen and Fischer, Markus and M{\"u}ller, J{\"o}rg and Prati, Daniel and Socher, Stephanie A. and Jeltsch, Florian}, title = {Grazing response patterns indicate isolation of semi-natural European grasslands}, series = {Oikos}, volume = {123}, journal = {Oikos}, number = {5}, publisher = {Wiley-Blackwell}, address = {Hoboken}, issn = {0030-1299}, doi = {10.1111/j.1600-0706.2013.00957.x}, pages = {599 -- 612}, year = {2014}, abstract = {Identifying drivers of species diversity is a major challenge in understanding and predicting the dynamics of species-rich semi-natural grasslands.
