The XI international conference Stochastic and Analytic Methods in Mathematical Physics was held in Yerevan 2 – 7 September 2019 and was dedicated to the memory of the great mathematician Robert Adol’fovich Minlos, who passed away in January 2018.
The present volume collects a large majority of the contributions presented at the conference on the following domains of contemporary interest: classical and quantum statistical physics, mathematical methods in quantum mechanics, stochastic analysis, applications of point processes in statistical mechanics. The authors are specialists from Armenia, Czech Republic, Denmark, France, Germany, Italy, Japan, Lithuania, Russia, UK and Uzbekistan.
A particular aim of this volume is to offer young scientists basic material in order to inspire their future research in the wide fields presented here.
Background
In Europe, bank voles (Myodes glareolus) are widely distributed and can transmit Puumala virus (PUUV) to humans, which causes a mild to moderate form of haemorrhagic fever with renal syndrome, called nephropathia epidemica. Uncovering the link between host and virus dynamics can help to prevent human PUUV infections in the future. Bank voles were live trapped three times a year in 2010–2013 in three woodland plots in each of four regions in Germany. Bank vole population density was estimated and blood samples collected to detect PUUV specific antibodies.
Results
We demonstrated that fluctuation of PUUV seroprevalence is dependent not only on multi-annual but also on seasonal dynamics of rodent host abundance. Moreover, PUUV infection might affect host fitness, because seropositive individuals survived better from spring to summer than uninfected bank voles. Individual space use was independent of PUUV infections.
Conclusions
Our study provides robust estimations of relevant patterns and processes of the dynamics of PUUV and its rodent host in Central Europe, which are highly important for the future development of predictive models for human hantavirus infection risk.
Protein interaction and protein imaging strongly benefit from the advancements in time-resolved and superresolution fluorescence microscopic techniques. However, the techniques were typically applied separately and ex vivo because of technical challenges and the absence of suitable fluorescent protein pairs. Here, we show correlative in vivo fluorescence lifetime imaging microscopy Forster resonance energy transfer (FLIM-FRET) and stimulated emission depletion (STED) microscopy to unravel protein mechanics and structure in living cells. We use magnetotactic bacteria as a model system where two proteins, MamJ and MamK, are used to assemble magnetic particles called magnetosomes. The filament polymerizes out of MamK and the magnetosomes are connected via the linker MamJ. Our system reveals that bacterial filamentous structures are more fragile than the connection of biomineralized particles to this filament. More importantly, we anticipate the technique to find wide applicability for the study and quantification of biological processes in living cells and at high resolution.

Genisa-Blätter III
(2020)
Ursprünglich sollten die „Genisa-Blätter III“ ein europäisches Projekt werden. Veröffentlicht werden sollten Quellen aus Genisot, die im vormals deutschsprachigen Raum gehoben wurden. Das Vorhaben scheiterte. Nunmehr sind im Band sieben Beiträge versammelt, in denen kenntnisreich Funde aus den Ablagen in Alsenz, Altenschönbach, Memmelsdorf, Reckendorf und Veitshöchheim besprochen werden. Der achte Aufsatz knüpft am internationalen Vorhaben an: Im Mittelpunkt des Artikels stehen drei Genisafunde aus Tschechien, genauer gesagt aus den beiden ostböhmischen Ortschaften Luže und Rychnov nad Kněžnou. Alle acht Beiträge gemeinsam verdeutlichen die inhaltliche Spannbreite von Genisot, die sich die Forschung zunutze machen kann: Sie reicht von Aspekten der Wirtschaft und des Rechts, über die Religion bis hin zum alltäglichen Leben und bietet jeweils eigene Geschichten im Spannungsfeld des möglichen Scheiterns.
This review analyzes the potential role and long-term effects of field perennial polycultures (mixtures) in agricultural systems, with the aim of reducing the trade-offs between provisioning and regulating ecosystem services. First, crop rotations are identified as a suitable tool for the assessment of the long-term effects of perennial polycultures on ecosystem services, which are not visible at the single-crop level. Second, the ability of perennial polycultures to support ecosystem services when used in crop rotations is quantified through eight agricultural ecosystem services. Legume-grass mixtures and wildflower mixtures are used as examples of perennial polycultures, and compared with silage maize as a typical crop for biomass production. Perennial polycultures enhance soil fertility, soil protection, climate regulation, pollination, pest and weed control, and landscape aesthetics compared with maize. They also score lower for biomass production compared with maize, which confirms the trade-off between provisioning and regulating ecosystem services. However, the additional positive factors provided by perennial polycultures, such as reduced costs for mineral fertilizer, pesticides, and soil tillage, and a significant preceding crop effect that increases the yields of subsequent crops, should be taken into account. However, a full assessment of agricultural ecosystem services requires a more holistic analysis that is beyond the capabilities of current frameworks.
Reaching the Sustainable Development Goals requires a fundamental socio-economic transformation accompanied by substantial investment in low-carbon infrastructure. Such a sustainability transition represents a non-marginal change, driven by behavioral factors and systemic interactions. However, typical economic models used to assess a sustainability transition focus on marginal changes around a local optimum, whichby constructionlead to negative effects. Thus, these models do not allow evaluating a sustainability transition that might have substantial positive effects. This paper examines which mechanisms need to be included in a standard computable general equilibrium model to overcome these limitations and to give a more comprehensive view of the effects of climate change mitigation. Simulation results show that, given an ambitious greenhouse gas emission constraint and a price of carbon, positive economic effects are possible if (1) technical progress results (partly) endogenously from the model and (2) a policy intervention triggering an increase of investment is introduced. Additionally, if (3) the investment behavior of firms is influenced by their sales expectations, the effects are amplified. The results provide suggestions for policy-makers, because the outcome indicates that investment-oriented climate policies can lead to more desirable outcomes in economic, social and environmental terms.
Preface
(2020)
Since 2004 a giant portrait of the ancient Dacian king Decebalus can be seen by people visiting the Đerdap national park in Serbia or sailing along the Danube. The location is carefully chosen: the ancient king is located on the other side of the river, within the Romanian Parcul Natural Porțile de Fier, but is carved in the rock so to look in the direction from where, at the beginning of the 2nd century CE, the Romans came to move war to him and his people. Not by chance, on the Serbian side of the river and not far away from the sculpture is the Tabula Traiana, a Roman inscription celebrating the opening of the Roman road leading here in 100 CE. This article moves from the role of ancient Rome in the historical cultures and national identities of the two countries facing each other here, Serbia and Romania, in order to explain how the Romans represented a ‘contested identity’ and therefore why, at the end of the 20th century, the Romanian nationalistic millionaire G. C. Drăgan decided to invest a humongous quantity of money in the realization of the sculpture of Decebalus.
Studies on the “uses of the past” have steadily and consistently advanced over the past twenty years. Following the seminal studies by Hobsbawm and Ranger and Benedict Anderson on the role of narratives of the past in constructing (national) identities, and thanks the always more widespread practice of reception studies, the attention for cultural memory and lieux de mémoire, and following, many publications have investigated the role of nearer and further time layers in defining and determining structures of identity and senses of belonging across the world. Didactics of history has also contributed a great deal to this field of studies, also thanks to the always more refined methodologies of school book analysis. Classical Antiquity has obviously not been neglected, and multiple studies have been dedicated to its role in the development and reinforcement of modern identities. Yet, not only some areas of the world have remained less considered than others, but most attention has been dedicated to national identities, nationalistic discourses, and their activation through historical narratives. This special issues of thersites wants to contribute further to research on the role of Classical Antiquity within modern identities, asking scholars to focus especially on areas that have been less strongly represented in scholarship until now.
