Gauged Supergravities in Three Dimensions: A Panoramic Overview

Maximal and non-maximal supergravities in three spacetime dimensions allow for a large variety of semisimple and non-semisimple gauge groups, as well as complex gauge groups that have no analog in higher dimensions. In this contribution we review the recent progress in constructing these theories and discuss some of their possible applications.Comment: 32 pages, 1 figure, Proceedings of the 27th Johns Hopkins workshop: Goteborg, August 2003; references adde

Anatolian glosses in the Akkadian medical omina

The paper provides a thorough linguistic analysis of all the Anatolian glosses included in the manuscripts of the Akkadian medical omina found at Boğazköy/Hattuša. In particular, we will discuss their etymology, function in the texts, sociolinguistic value, and make some remarks on the purpose that manuscripts with glosses could have had

K3 surfaces with involution, equivariant analytic torsion, and automorphic forms on the moduli space IV: The structure of the invariant

Yoshikawa in [Invent. Math. 156 (2004), 53–117] introduces a holomorphic torsion invariant of K3 surfaces with involution. In this paper we completely determine its structure as an automorphic function on the moduli space of such K3 surfaces. On every component of the moduli space, it is expressed as the product of an explicit Borcherds lift and a classical Siegel modular form. We also introduce its twisted version. We prove its modularity and a certain uniqueness of the modular form corresponding to the twisted holomorphic torsion invariant. This is used to study an equivariant analogue of Borcherds’ conjecture

Experimental and theoretical investigations in rare earth-triel-tetrel polar intermetallic systems: composition-structure-properties relationships

This dissertation consists of eight chapters, which include experimental and theoretical studies of novel polar intermetallics and Zintl phases to understand the interrelationships among stoichiometry, structure and properties. Chapter 1 shows general introduction and motivation including a preview of projects. The main part of my doctoral research starts from Chapter 2, and four subsequent chapters are about the investigations of RE(M1-xM’x)2 systems, where RE is rare-earth metals, and M and M’ are Group 12–14 elements. To gain insights into driving forces determining their crystal structures at the given compositions, I exploited two controllable factors one at a time which were the atomic size and the valence electron counts. In Chapter 2: ‘Planar versus Puckered Nets in the Polar Intermetallic Series EuGaTt (Tt = Si, Ge, Sn)’, only the atomic size was changed by substituting tetrels to see the impact of atomic size to the crystal and electronic structures. On the other hand, in Chapter 3 and 4: ‘To What Extent Does the Zintl-Klemm Formalism Work? The Eu(Zn1—xGex) (0 ≤ x ≤ 1) Series’ and ‘Theoretical Interpretation of the Structural Transition along the Eu(Zn1—xGex) (0 ≤ x ≤ 1) Series’, I attempted to reduce the atomic size factor and to focus on valence electron count for the series only by altering atomic compositions. In Chapter 5: ‘Structure-Composition Sensitivities in “Metallic” Zintl Phase: A study of Eu(Ga1—xTtx) (Tt = Si, Ge; 0 ≤ x ≤ 1) Series’, I exploited two controllable factors, which are atomic size and valence electron counts, simultaneously, and compared the results with two previously investigated systems. Other parts of my research are composed of Chapter 6 and 7, which are respectively, ‘On the “Coloring Problem” in YMgZn and Related Phase’ and ‘Phase Width and Site Preference in the EuMgxGa4—x Series’:. In these two chapters, I tried to understand the observed phase widths of certain structural types from the perspective of particular chemical bondings. General conclusion of my overall doctoral research is shown in Chapter 8

Le feste ittite del tuono

The book contains the philological edition of the corpus of Hittite texts currently collected under number 631 of the Catalogue des Textes Hittites by E. Laroche. They constitute the description of religious ceremonies celebrated in connection with the atmospheric phenomenon of thunder, interpreted as a manifestation of the god of the storm, which was the greatest divinity of the Hittite pantheon. The documents of major extension, presented with a transliteration and translation, are accompanied by a philological comment, aimed at highlighting their structure as well as lexical and grammatical peculiarities, and are introduced by an analysis of dating conducted on a palaeographic basis. The minor fragments are presented in transcription and, where possible, in translation. The text discusses the possible attribution of each fragment to the corpus, based on structure and content. The critical edition of the texts is preceded by an introductory chapter in which the nature of thunder-related festivities and their status in the Hittite cultural calendar are discussed

Dissecting the multispecies interaction network at the A. thaliana root-soil interface

In nature, healthy and asymptomatic plants cohabit with a variety of microbes, such as bacteria, fungi, and oomycetes, forming complex microbial consortia that interact with each other and likely provide fitness benefits to the host plant. Advances in culture-independent methods have deepened our understanding on microbial communities’ distribution in nature and the environmental factors shaping these communities. However, there is still a lack of consensus between studies and a more holistic approach is needed, by studying several microbial groups under a variety of environmental conditions. Importantly, there is a significant part of the microbial variance that remains unexplained in host-associated microbiota studies. Decades of research have shown that microbes interact with each other, indicating that microbe-microbe interactions might represent a major, yet poorly described, force driving microbial community establishment in and outside plant roots. In order to assess microbial communities´ functions and assembly rules, microbiota reconstitution experiments in gnotobiotic plant systems are needed. By linking microbial community profiling data from natural Arabidopsis thaliana populations (chapter I) with reconstruction experiments with synthetic microbial communities and germ-free plants (chapter II), I provide novel insight into how environment, host-microbe and microbe-microbe interactions affect microbial community structure and plant health in nature. In the first chapter, I analyzed bacterial, fungal and oomycetal communities associated with Arabidopsis thaliana roots from seventeen natural populations across a European transect, for three consecutive years. By developing a fractionation protocol that distinguishes four microbial niches (Soil, Rhizosphere, Rhizoplane and Root), I dissected the relevance of host compartment, host species, biogeography, harvesting year, and soil characteristics on microbial communities’ distribution at a continental scale. I showed that bacterial, fungal and oomycetal communities are primarily shaped by different factors, including the host niche for bacteria, the site for fungi, and the year for oomycetes. Also, I identified an A.thaliana root-associated core microbiota, resilient across harvesting years and locations. Furthermore, reciprocal transplant experiments conducted in natural and controlled conditions uncovered the important role of climate as well as the climate-dependent host genotype effect on microbial communities’ distribution. In the second chapter, I utilized a gnotobiotic plant system for reconstituting multispecies synthetic microbial communities, which revealed the relevance of multi-kingdom microbe-microbe interactions for plant health and microbial communities’ assembly. In these experiments the bacterial microbiota is essential for plant survival and protection against detrimental activities of root-derived filamentous eukaryotes. Moreover, I revealed that microbial load only partially drives plant health and that disease protection of bacterial root commensals is a redundant trait needed to maintain microbial interkingdom balance for plant health. Finally, I investigated the dynamics of microbiota establishment and explored the importance of the host for microbiota establishment
