We here formulate a stochastic model based on a generalised Langevin equation in which non-Gaussian shapes of the probability density function and normal or anomalous diffusion have a common origin, namely a random parametrisation of the stochastic force. We perform a detailed analysis demonstrating how various types of parameter distributions for the memory kernel result in exponential, power law, or power-log law tails of the memory functions. The studied system is also shown to exhibit a further unusual property: the velocity has a Gaussian one point probability density but non-Gaussian joint distributions. This behaviour is reflected in the relaxation from a Gaussian to a non-Gaussian distribution observed for the position variable. We show that our theoretical results are in excellent agreement with stochastic simulations.}, language = {en} } @phdthesis{Oeztuerk2018, author = {{\"O}zt{\"u}rk, Ugur}, title = {Learning more to predict landslides}, doi = {10.25932/publishup-42643}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-426439}, school = {Universit{\"a}t Potsdam}, pages = {xxi, 104}, year = {2018}, abstract = {Landslides are frequent natural hazards in rugged terrain, when the resisting frictional force of the surface of rupture yields to the gravitational force. These forces are functions of geological and morphological factors, such as angle of internal friction, local slope gradient or curvature, which remain static over hundreds of years; whereas more dynamic triggering events, such as rainfall and earthquakes, compromise the force balance by temporarily reducing resisting forces or adding transient loads. This thesis investigates landslide distribution and orientation due to landslide triggers (e.g. rainfall) at different scales (6-4∙10^5 km^2) and aims to link rainfall movement with the landslide distribution. It additionally explores the local impacts of the extreme rainstorms on landsliding and the role of precursory stability conditions that could be induced by an earlier trigger, such as an earthquake. Extreme rainfall is a common landslide trigger. Although several studies assessed rainfall intensity and duration to study the distribution of thus triggered landslides, only a few case studies quantified spatial rainfall patterns (i.e. orographic effect). Quantifying the regional trajectories of extreme rainfall could aid predicting landslide prone regions in Japan. To this end, I combined a non-linear correlation metric, namely event synchronization, and radial statistics to assess the general pattern of extreme rainfall tracks over distances of hundreds of kilometers using satellite based rainfall estimates. Results showed that, although the increase in rainfall intensity and duration positively correlates with landslide occurrence, the trajectories of typhoons and frontal storms were insufficient to explain landslide distribution in Japan. Extreme rainfall trajectories inclined northwestwards and were concentrated along some certain locations, such as coastlines of southern Japan, which was unnoticed in the landslide distribution of about 5000 rainfall-triggered landslides. These landslides seemed to respond to the mean annual rainfall rates. Above mentioned findings suggest further investigation on a more local scale to better understand the mechanistic response of landscape to extreme rainfall in terms of landslides. On May 2016 intense rainfall struck southern Germany triggering high waters and landslides. The highest damage was reported at the Braunsbach, which is located on the tributary-mouth fan formed by the Orlacher Bach. Orlacher Bach is a ~3 km long creek that drains a catchment of about ~6 km^2. I visited this catchment in June 2016 and mapped 48 landslides along the creek. Such high landslide activity was not reported in the nearby catchments within ~3300 km^2, despite similar rainfall intensity and duration based on weather radar estimates. My hypothesis was that several landslides were triggered by rainfall-triggered flash floods that undercut hillslope toes along the Orlacher Bach. I found that morphometric features such as slope and curvature play an important role in landslide distribution on this micro scale study site (<10 km^2). In addition, the high number of landslides along the Orlacher Bach could also be boosted by accumulated damages on hillslopes due karst weathering over longer time scales. Precursory damages on hillslopes could also be induced by past triggering events that effect landscape evolution, but this interaction is hard to assess independently from the latest trigger. For example, an earthquake might influence the evolution of a landscape decades long, besides its direct impacts, such as landslides that follow the earthquake. Here I studied the consequences of the 2016 Kumamoto Earthquake (MW 7.1) that triggered some 1500 landslides in an area of ~4000 km^2 in central Kyushu, Japan. Topography, i.e. local slope and curvature, both amplified and attenuated seismic waves, thus controlling the failure mechanism of those landslides (e.g. progressive). I found that topography fails in explaining the distribution and the preferred orientation of the landslides after the earthquake; instead the landslides were concentrated around the northeast of the rupture area and faced mostly normal to the rupture plane. This preferred location of the landslides was dominated mainly by the directivity effect of the strike-slip earthquake, which is the propagation of wave energy along the fault in the rupture direction; whereas amplitude variations of the seismic radiation altered the preferred orientation. I suspect that the earthquake directivity and the asymmetry of seismic radiation damaged hillslopes at those preferred locations increasing landslide susceptibility. Hence a future weak triggering event, e.g. scattered rainfall, could further trigger landslides at those damaged hillslopes.}, language = {en} } @article{ZuehlsdorfWinkler2018, author = {Z{\"u}hlsdorf, Felix and Winkler, Iris}, title = {Jenaer Kooperationsseminare aus Fachwissenschaft und Fachdidaktik}, series = {Koh{\"a}renz in der universit{\"a}ren Lehrerbildung}, journal = {Koh{\"a}renz in der universit{\"a}ren Lehrerbildung}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-418638}, pages = {219 -- 235}, year = {2018}, language = {de} } @misc{ZwiebackKokeljGuentheretal.2018, author = {Zwieback, Simon and Kokelj, Steven V. and G{\"u}nther, Frank and Boike, Julia and Grosse, Guido and Hajnsek, Irena}, title = {Sub-seasonal thaw slump mass wasting is not consistently energy limited at the landscape scale}, series = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, number = {926}, issn = {1866-8372}, doi = {10.25932/publishup-44568}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-445688}, pages = {549 -- 564}, year = {2018}, abstract = {Predicting future thaw slump activity requires a sound understanding of the atmospheric drivers and geomorphic controls on mass wasting across a range of timescales. On sub-seasonal timescales, sparse measurements indicate that mass wasting at active slumps is often limited by the energy available for melting ground ice, but other factors such as rainfall or the formation of an insulating veneer may also be relevant. To study the sub-seasonal drivers, we derive topographic changes from single-pass radar interferometric data acquired by the TanDEM-X satellites. The estimated elevation changes at 12m resolution complement the commonly observed planimetric retreat rates by providing information on volume losses. Their high vertical precision (around 30 cm), frequent observations (11 days) and large coverage (5000 km(2)) allow us to track mass wasting as drivers such as the available energy change during the summer of 2015 in two study regions. We find that thaw slumps in the Tuktoyaktuk coastlands, Canada, are not energy limited in June, as they undergo limited mass wasting (height loss of around 0 cm day 1) despite the ample available energy, suggesting the widespread presence of early season insulating snow or debris veneer. Later in summer, height losses generally increase (around 3 cm day 1), but they do so in distinct ways. For many slumps, mass wasting tracks the available energy, a temporal pattern that is also observed at coastal yedoma cliffs on the Bykovsky Peninsula, Russia. However, the other two common temporal trajectories are asynchronous with the available energy, as they track strong precipitation events or show a sudden speed-up in late August respectively. The observed temporal patterns are poorly related to slump characteristics like the headwall height. The contrasting temporal behaviour of nearby thaw slumps highlights the importance of complex local and temporally varying controls on mass wasting.}, language = {en} } @misc{ZwickelKahlRychliketal.2018, author = {Zwickel, Theresa and Kahl, Sandra M. and Rychlik, Michael and M{\"u}ller, Marina E.

Simultaneous production of up to 15 (modified) Altemaria toxins by members of the A. tenuissima, A. arborescens, A. altemata species-groups and up to seven toxins by A. infectoria strains was demonstrated. Overall tenuazonic acid was the most extensively formed mycotoxin followed by alternariol and alternariol mono methylether, whereas altertoxin I was the most frequently detected toxin. Sulfoconjugated modifications of alternariol, alternariol mono methylether, altenuisol and altenuene were frequently determined. Unknown perylene quinone derivatives were additionally detected. Strains of the species-group A. infectoria could be segregated from strains of the other three species-groups due to significantly lower toxin levels and the specific production of infectopyrone.

Zadok's innovative writings. According to most scholars R. Zadok continues the doctrine of his rabbi R. Mordechai Yosef Leiner of Izbica and introduces existential fatalism: man has the freedom to act against the customary law, according to God's will which is revealed in his heart, even in his passions, which exceed the Halacha; however, man does not determine the will that is revealed in the root of his soul, but only uncovers it. Many expressions, in content and form, of this fatalism can be found in R. Zadok's writings; yet, he also introduces many remarks about human free choice and its creative power to establish and determine man's root and re-establish and influence the Divine worlds and this world. This research focuses on these passages whose centrality has been so far neglected by research. Hence, its renewed understanding of his doctrine. R. Zadok's position can be explained by means of the paradoxical perception, which claims the full strength of the two opposites and even a mutual influence between them, which creates a difficult yet fertile tension: as opposed to the a priori intellectual and formal process of fatalism where Divine Foreknowledge eliminates free choice, R. Zadok introduces fatality which identifies in reality itself the Divine foreknowledge and will that exist in all things. In R. Zadok's fatality, Divine foreknowledge does not eliminate free choice; on the contrary, without Divine foreknowledge, nothing has existence. Therefore, only the existence of Divine foreknowledge within free choice enables its true and indeed free fulfillment. R. Zadok's ontological perception is realized not only in the direct content of his words but also indirectly, in the method of his exegesis and the sense he gives to the concepts he discusses. Therefore the fatality is revealed in other areas in which there is a gap between the absolute dimension ('Yedi'ah') and the contingent dimension ('Bechirah'): the lie, imagination, evil, sin, suffering etc., indeed contingent compared with the absoluteness of truth, good, etc.; however, according to R. Zadok, God wants them as such - that is to say, they have an essential existence and actuality that are not absolute, but rather as such: as contingent, temporary and relative. However, these essential existence and actuality do not confirm them as they are but create a transformation within them. For example, evil does not become absolute good or remains evil but rather turns into 'Very Good' (Tov Me'od) which includes evil and according to Rabbi Zadok is greater than regular good. From this, rises also the opposite influence: that of free choice, or contingent Bechira in general, on Divine Foreknowledge, or absolute Yediah in general. According to R. Zadok, when the contingency and relativity of "Bechirah" received its essential existence and actuality, it has the power so to speak, to add dynamism to the permanent Divine absoluteness of the 'Yedi'ah': the affliction (Nega; נגע) of sin or suffering turns by itself, by interchanging its letters, into pleasure (Oneg; ענג) which is greater than regular delight. Man has the power to influence the upper worlds by decreeing decrees or by canceling Divine decrees; he also has the power to influence the daily novelties of this world, by the novellaes of the Oral Law and the sanctification of the new month which is capable of changing the movement of the zodiac. The human creativity of the novellae of the Oral Law is included in the Divine truth which is hidden in the Written Law and it only reveals and interprets the latter; but on the other hand, according to R. Zadok, the source of the dynamic vital novellaes of the Oral Law is higher than the source of the permanent absoluteness of Written Law and they are those which create and determine the latter. R. Zadok introduces two main concepts for his paradox: On the ontological perception - Yichud Gamur, the Ultimate Unification of God, in which the contingent duality (between God and His creation, and the choice it enables) of the Lower Unification paradoxically exists with the absolute unification and Divine Foreknowledge of the Upper Unification. On the perception of man's existential situation - HaShoresh HaNe'elam, The Hidden Root: unlike Rabbi Mordechai Yosef, his rabbi, rabbi Zadok claims that man determines his destiny by his willful contingent actions - yet, simultaneously, like his rabbi, he also claims that the man's permanent root is determined by God and His Foreknowledge and it is what determines his actions for better or worse. But above these R. Zadok points to an additional Hidden Root which is higher than the permanent one: it is indeed an absolute root (Yediah) yet is determined and established by man's willful actions (Bechira), similar to the Divine creation of 'ex nihilo'.}, language = {mul} } @techreport{Zivkovic2018, type = {Working Paper}, author = {Zivkovic, Velimir}, title = {International Rule of Law Through International Investment Law}, series = {KFG Working Paper Series}, journal = {KFG Working Paper Series}, number = {16}, issn = {2509-3770}, doi = {10.25932/publishup-42218}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-422181}, pages = {33}, year = {2018}, abstract = {In challenging times for international law, there might be a heightened need for both analysis and prescription.

It enables us to express ourselves, to communicate and understand, to help and get help, to create and share togetherness. However, that does not completely capture the value of language. "Language belongs to the character of man," said the English philosopher Sir Francis Bacon. If you believe the poet Johann Gottfried von Herder, a human is "only a human through language". Ultimately, this means that we live in our world not with, but in, language. We not only describe our reality by means of language, but language is the device through which we open up the world in the first place. It is always there and shapes and influences us and the way we perceive, analyze, describe and ultimately determine everything around us. Since it is so deeply connected with human nature, it is hardly surprising that our language has always been in the center of academic research - and not only in those fields that bear the name linguistics. Philosophy and media studies, neurology and psychology, computer science and semiotics - all of them are based on linguistic structures and their premises and possibilities. Since July 2017, a scientific network at the University of Potsdam has been working on exactly this interface: the Collaborative Research Center "Limits of Variability in Language" (SFB 1287), funded by the German Research Foundation (DFG). Linguists, computer scientists, psychologists, and neurologists examine where language is or is not flexible. They hope to find out more about individual languages and their connections. In this issue of Portal Wissen, we asked SFB spokeswoman Isabell Wartenburger and deputy spokesman Malte Zimmermann to talk about language, its variability and limits, and how they investigate these aspects.
