description: Автором рассматриваются задачи построения регрессионных зависимостей для целей стоимостной оценки. Поскольку нередко отклонения цен от таких зависимостей имеют распределение, отличающееся от нормального, известные робастные методы позволяют это учесть, но не позволяют выбрать лучший вид регрессионной зависимости, автор предлагает оценивать калибровочные параметры регрессионных зависимостей, опираясь на принцип максимального правдоподобия и используя альтернативные вероятностные распределения отклонений, имеющие более тяжелые «хвосты». Приводятся примеры применения такого метода к оценке машин, оборудования и зданий.

description: The germline encoding of a non-immune immunoglobulin M molecule in mammals was experimentally documented for the first time as a result of the specifically timed ovariectomy of C57BL/10 mice. The target of this innate antibody is a trans-species developmental antigen that signifies malignancy when expressed in any non-developmental tissue. Although ovariectomy and castration result in uncontrolled and/or enhanced humoral and cellular immunity involving increased weights of the spleen and thymus with pronounced B and T cell production, the development of mercaptoethanol-sensitive, complement-binding, non-immune anti-A reactivity in murine plasma was not enhanced after an ovariectomy that was performed in C57BL/10 mice prior to the onset of puberty. This non-immune murine anti-A, which is complementary to the trans-species, syngeneic ovarian GalNAc-glycan-bearing glycolipids and distinct from the cross-reactive adaptive anti-A antibody, was strongly downregulated or did not appear in plasma of animals ovariectomized at the age of 20 days. Thus, contrary to our previous view, this reactivity is unlikely to originate from a somatic, primary immune or autoimmune response. All of the murine tissues expressed the species-specific Forssman reactivity, and further A-like structures were identified in the male and female reproductive and endodermal organs by reaction with innate human anti-A antibody, while the murine anti-A was exclusively inhibited by syngeneic ovarian glycolipids. Moreover, the early ovarian tissue, which represents a last evolutionary and/or developmental location, showed a developmental polymorphism characterized by reactivity to the lectins from Dolichos biflorus and the agglutinin from Helix pomatia indicating the functional involvement of O-GalNAc-determined mucin-type A-like Tn and TF epitopes that signify malignancy when expressed by non-developmental tissues.
A fermion phenomenology of low-temperature strongly-noncrystalline solids

description: Insisting on the relevance of spin-statistics theorem, I propose that anomalous low-energy excitations of strongly-noncrystalline solids (SNSs), observed at low temperatures T < 1 K, are fermions, which are localized and weakly interacting. This phenomenological theory rationalizes all low-energy quantum many-body states of SNSs as Goldstone bosons-phonons and half-integer-spin fermions. Fermi glass, rather than isolated two-level systems (TLSs), appears to be a consistent theory of various thermal and nonlinear response properties of SNSs. A robust consequence of this theory is nearly constant-in-energy density of fermion states near Fermi energy, which in turn implies linear-in-temperature specific heat and frequency-independent sound internal friction. Consistent parameters of Landau-Fermi glass are calculated on theoretical grounds as well as from experimental data.

Reachable Set Characterization of Open Quantum System by Quantum Speed Limit
Creators: name: Kobayashi, Kohei
Publisher: name: arXiv
Year: 2021
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In recent years, Arenz et al. proposed the idea of reachable set characterization based on the quantum speed limit (QSL); that is, the reachable set of the target unitary gate in a closed qubit system can be characterized by considering the QSL as the necessary condition that the control setup must satisfy in order to achieve the goal. Inspired by this idea, in this paper we characterize a general Markovian open quantum system based on the QSL derived in \cite{Kohei2}. Note that this bound is not only explicitly computable with respect to system parameters, but also tighter than the other bounds. Some examples for demonstrating this analysis will be given.

Supersymmetric vortex loops in 3D gauge theories

description: We give a precise definition of BPS vortex loops in 3D non-abelian gauge theories with ${\cal N}=2$ SUSY by the path integral over fields with a prescribed singular behavior. We compute the expectation value of a BPS vortex loop on an ellipsoid. Using the result we revisit the known equivalence between Wilson and vortex loops in pure Chern-Simons theory. Naive computations of expectation values in ${\cal N}=2$ theory leads to an unwanted shift of parameters in the rule of correspondence. We resolve the problem by relating the shift to the global anomaly of ${\cal N}=2$ SUSY quantum mechanics. For theories with $U(N)$ gauge group we also develop an alternative description of vortex loops in terms of 1D ${\cal N}=2$ SUSY quantum mechanics on their worldline. For vortex loops in ${\cal N}=4$ theories, our construction reproduces some of the quiver GLSMs of Assel and Gomis.

description: We investigate the dineutron in the $2^+_1$ state of $^6$He via analysis of its decay mode by using the complex scaling method. In this letter, we propose the cross section for the resonant state to distinguish the resonant contributions from the nonresonant ones. As the results, it is found that the shoulder peak appears in the cross section for the resonant state as a function of $\varepsilon_{n\text{-}n}$. Furthermore, we show that the $S$ = 0 component of the cross section, where $S$ is the total spin of the valence two neutrons, has a peak around the shoulder peak, which comes from the dineutron configuration in the $2^+_1$ state. Thus we conclude that the shoulder peak is expected to indicate the existence of the dineutron in the $2^+_1$ state.

Report on the conducted communication and dissemination activities with an update of the communication and dissemination plan.

Work package in charge

WP10

Executive summary

This deliverable updates the nextGEMS project communication and dissemination plan and details activities that have been done in the first half of the project. The main objective of the communication and dissemination activities is to provide regular project communication and dissemination targeting various audiences, from the scientific community to many societal actor groups, as the first step towards a more profound engagement with stakeholders and future users of project results. Besides using standard science communication approaches, such as peer-reviewed articles, participation at conferences, social media, and the project website, nextGEMS also explores and applies innovative communication and dissemination approaches and tools. These include Vlogs (the video communication), science explainers, and storylines. The communication and dissemination activities are part of WP10 and the Storms & Society theme, and the main two partners responsible for its implementation are Barcelona Supercomputing Center (BSC) and Latest Thinking (LT). However, the activities are deployed in close collaboration with all consortium members and project participants.

Conclusion & Results

The project communication and dissemination activities follow the principles of visibility, transparency, plurality, and usability. This includes ensuring visibility of the project and its outcomes for a wide range of stakeholder circles; being transparent on the evolution of the nextGEMS scientific production; plurality in the perspectives included and reached with the different communication and dissemination products; and usability by tailoring the scientific outputs with and for different stakeholder groups and using communication approaches for starting knowledge coproduction. Particularly interesting are nextGEMS’s three innovative communication and engagement approaches: videos, science explainers, and storylines. Developing four different types of videos, nextGEMS tailors them to all six stakeholder groups targeted by the project. So far, the project has produced 17 videos. Already becoming a leitmotif and recognisable mark of nextGEMS, these short, visually appealing, videos prepared in an accessible language are considered extremely powerful communication tools, that can be easily disseminated through social media, showcased at events, or distributed in other ways. The next innovative communication tool is science explainers which show the driving ideas and progress from nextGEMS scientists in plain language and different formats. Finally, an important approach for disseminating project outcomes will be through storylines. The co-exploration and co-design activities have already started for the two project storylines, as detailed in D10.3.

description: In this paper, we present the findings from a survey study to investigate how developers and managers define and trade-off developer productivity and software quality (two related lenses into software development). We found that developers and managers, as cohorts, are not well aligned in their views of what it means to be productive (developers think of productivity in terms of activity, while more managers think of productivity in terms of performance). We also found that developers are not accurate at predicting their managers' views of productivity. In terms of quality, we found that individual developers and managers have quite varied views of what quality means to them, but as cohorts they are closely aligned in their different views, with the majority in both groups defining quality in terms of robustness. Over half of the developers and managers reported that quality can be traded for higher productivity and why this trade-off can be justified, while one third consider quality as a necessary part of productivity that cannot be traded. We also present a new descriptive framework for quality, TRUCE, that we synthesize from the survey responses. We call for more discussion between developers and managers about what they each consider as important software quality attributes, and to have open debate about how software quality relates to developer productivity and what trade-offs should or should not be made.

description: Based on the diagnostic morphological characters of the Arundo taxa, and after both field and herbarium observation, three species (A. micrantha, A. plinii and A. donax) were found along the eastern Adriatic coast. Altogether, 50 phytocoenological relevés from Arundo stands were collected in Croatia, Montenegro and Albania between 2010 and 2013. Three associations with a predominance of Arundo species were determined: Arundinetum plinianae, Arundinetum micranthae and Arundini donacis–Convolvuletum sepium. Among them, Arundinetum micranthae is described and proposed as a new association, belonging to the Artemisietea vulgaris class. It occurs frequently along the coastal belt between the cities of Split and Dubrovnik in South Croatia. The syntaxonomy of the associations is discussed and comparison with similar communities from Italy is made. The vegetation and floristic structure of the associations is discussed as a potential basis for biodiversity conservation programmes and for evaluating the state of these ecosystems in the future.

description: We discuss general bosonic configurations of four-dimensional N=2 supergravity coupled to vector multiplets in (t,s) space-time. The supergravity theories with Euclidean and neutral signature are described by the so-called para-special Kähler geometry. For extremal solutions, we derive in a unified fashion, using the equations of motion, the flow equations for all space-time signatures. Demanding that the solutions with neutral and Euclidean signatures admit unbroken supersymmetry, we derive the constraints, known as the stabilisation equations, on the para-covariantly holomorphic sections expressed in terms of the adapted coordinates. The stabilisation equations expressed in terms of the para-complex sections imply generalised flow equations in terms of para-complex central charge. For Euclidean and neutral signature, it is demonstrated that solutions for either signs of gauge kinetic terms are mapped into each other via field redefinitions.

description: A family of nonsingular rational solutions of the Kadomtsev-Petviashvili (KP) I equation are investigated. These solutions have multiple peaks whose heights are time-dependent and the peak trajectories in the $xy$-plane are altered after collision. Thus they differ from the standard multi-peaked KPI simple $n$-lump solutions whose peak heights as well as peak trajectories remain unchanged after interaction.The anomalous scattering occurs due to a non-trivial internal dynamics among the peaks in a slow time scale. This phenomena is explained by relating the peak locations to the roots of complex heat polynomials. It follows from the long time asymptotics of the solutions that the peak trajectories separate as $O(\sqrt{|t|})$ as $|t| \to \infty$, and all the peak heights approach the same constant value corresponding to that of the simple 1-lump solution. Consequently, a multi-peaked $n$-lump solution evolves to a superposition of $n$ 1-lump solutions asymptotically as $|t| \to \infty$.

description: Precision and accuracy of quantitative scanning transmission electron microscopy (STEM) methods such as ptychography, and the mapping of electric, magnetic and strain fields depend on the dose. Reasonable acquisition time requires high beam current and the ability to quantitatively detect both large and minute changes in signal. A new hybrid pixel array detector (PAD), the second-generation Electron Microscope Pixel Array Detector (EMPAD-G2), addresses this challenge by advancing the technology of a previous generation PAD, the EMPAD. The EMPAD-G2 images continuously at a frame-rates up to 10 kHz with a dynamic range that spans from low-noise detection of single electrons to electron beam currents exceeding 180 pA per pixel, even at electron energies of 300 keV. The EMPAD-G2 enables rapid collection of high-quality STEM data that simultaneously contain full diffraction information from unsaturated bright field disks to usable Kikuchi bands and higher-order Laue zones. Test results from 80 to 300 keV are presented, as are first experimental results demonstrating ptychographic reconstructions, strain and polarization maps. We introduce a new information metric, the Maximum Usable Imaging Speed (MUIS), to identify when a detector becomes electron-starved, saturated or its pixel count is mismatched with the beam current.

description: Unexplained variations of the decay rate for weak interaction decays such as $β^{\pm}$-decay, electron capture, as well as strong interaction $α$-decay have been reported. Some researcher interpreted these variations as caused by an unexplained fundamental interaction. The purpose of the paper is to review decay rate parameter variations experiments and place them into a common comparable context and to make decay parameter measurements at the level of 10$^{-5}$ in the presences of an antineutrino flux, $\sim 3 \times10^{12}$ $\overlineν \, cm^{-2} \, sec^{-1}$, 6.5 meters from the High Flux Isotope Reactor(HFIR) reactor core having an on-off cycle time of $\sim$30 days. Two weak interaction decays, one via electron capture and the other via $β^-$ decay were selected because the final state and the time reverse state each contain a neutrino and anti-neutrino, covering arguments that the anti-neutrino flux may interact differently or not at all in one of the cases. The experiment searched for variation of the $^{54}_{25}$Mn, e$^-$ capture and $^{137}_{~55}$Cs, $β^-$ decay rate parameters. The measured variation in the decay rate parameters are found to be $δλ/ λ= (0.034\pm 1.38)\times 10^{-5}$ for $^{54}_{25}$Mn and $δλ/ λ= (0.67\pm 1.56)\times 10^{-5}$ for $^{137}_{~55}$Cs. These results are consistent with no measurable decay rate parameter variation due to an antineutrino flux, yielding a $68\%$ confidence level upper limit sensitivity for $^{54}_{25}$Mn, $δλ/ λ\leq 1.31\times10^{-5}$ or $σ\leq 1.29\times10^{-25}\,cm^{2}$ in cross section and for $^{137}_{~55}$Cs, $δλ/ λ\leq 2.23\times10^{-5}$ or $σ\leq 5.69\times10^{-27}\,cm^{2}$. These null or no observable effect measurements places cross-section upper limits $\sim 10^{4}$ times more sensitive than past experiments.

description: The controversial hypothesis that 'Oumuamua (1I/2017 U1) was an alien craft dominated by a solar sail is considered using known physics for the two possible cases: controlled and uncontrolled flight. The reliability engineering challenges for an artifact designed to operate for 10^5 - 10^6 yr are also considerable. All three areas generate research programs going forward. The uncontrolled case could be either "anonymous METI" (messaging extraterrestrial intelligence) or "inadvertent METI". In the controlled case the nature of the origin star, trajectory guidance from the origin star to the Sun, and the identity of a destination star are all undecided. The "controlled" case has more strikes against it than the "uncontrolled" case, but neither suffers a knock-out blow, as yet. Some of the issues turn out not to be major obstacles to the alien craft hypothesis, but others weaken the case for it. Most, however, imply new studies. Some of these, e.g., intercept missions for new interstellar objects, are concepts being developed, and will be of value whatever these objects turn out to be. Overall, these considerations show that a many pronged, targeted, research program can be built around the hypothesis that'Oumuamua is an alien craft. The considerations presented here can also be applied to other interstellar visitors, as well as to general discussions of interstellar travel.

description: Perowskit-CIGS-Tandem-Solarzellen zeigen großes Potenzial Wirkungsgrade von über 30% zu erreichen und damit die Kommerzialisierung der Dünnschicht-Photovoltaik zu revolutionieren. Parasitäre Verlustmechanismen wie etwa eine unerwünschte Absorption von langwelligem Licht in den Kontaktschichten limitieren jedoch die maximale Effizienz der Tandem-Solarzellen. Diese Dissertation beschäftigt sich mit der Entwicklung hocheffizienter, semitransparenter Perowskitsolarzellen, der Minimierung parasitärer Verluste in deren Kontaktschichten und mit der Herstellung von gestapelten Tandem-Solarzellen mit CIGS als Partnerzelle. Dafür wird zunächst die Effizienz von opaken Perowskitsolarzellen durch die Implementierung einer zusätzlichen Fulleren-basierten Elektronenleiterschicht optimiert, was durch die Entwicklung eines neuartigen Nanopartikel-basierten Verfahrens zur Verbesserung der Benetzbarkeit unterstützt wird. Die Entwicklung spezieller transparenter Kontaktschichten aus Wasserstoff-dotiertem Indiumoxid (IO:H) und Indiumzinkoxid (IZO) erfolgt durch Kathodenzerstäubung unter variabler Zugabe von Sauerstoff- bzw. Wasserstoffgas. Die nachträgliche Kristallisation von amorphem IO:H führt zu besonders niedrigen Absorptionseigenschaften im nahen Infrarotbereich, was für die Anwendung in Tandem-Solarzellen von entscheidendem Vorteil ist. Semitransparente Perowskitzellen, die mit diesen Kontakten ausgestattet sind, erreichen hohe Effizienzen von über 15%und ermöglichen eine Steigerung der mittleren Zell-Transmission von 55% auf 75% verglichen mit kommerziellen Kontaktschichten wie Indiumzinnoxid (ITO). Durch diese Transmissionssteigerung werden Tandem-Solarzellen realisiert, die eine gemeinsame Zellfläche von 0,5 cm² und einen verbesserten Wirkungsgrad von bis zu 23,0% aufweisen. Die Analyse der optischen Verlustmechanismen der verschiedenen Tandem-Solarzellen mittels Simulations-gestützter Methoden zeigt unter anderem auf, dass der Beitrag der Kontaktschichten zu den parasitären Gesamtabsorptionsverlusten von ca. 60% auf 40% gesenkt werden kann.

description: The present paper deals with the leontiniid remains recovered from the Late Oligocene (Deseadan) levels of Quebrada Fiera, Mendoza Province, central-western Argentina. The material consists of an almost complete skull associated with 11 vertebrae, as well as some maxillary and mandibular fragments and postcranial elements of different individuals, enabling a life reconstruction. The comparative study allows morphological differences with respect to other Deseadan taxa to be established, such as Scarrittia, Leontinia, Ancylocoelus, Anayatherium and Elmerriggsia, leading to the proposal of the new taxon Gualta cuyana gen. et sp. nov. The new genus and species is close to Scarrittia canquelensis in having upper I1 more developed than I2–3, mainly by its greater crown-height, and the canine overlapping the P1; it differs from this species by the longer, narrower nasals, longer rostrum, I2 not reduced, P3–4 with shallow lingual sulcus, shorter cervical vertebrae, and shorter calcaneum, lacking navicular facet. The complete dentition and/or the larger I1 differentiate Gualta cuyana from Leontinia, Ancylocoelus and Anayatherium ekecoa, as well as from the Miocene Colpodon. The lingual sulcus on P3–4 is much shallower than in Scarrittia barranquensis, Leontinia, Anayatherium and Elmerriggsia. The phylogenetic analysis shows poorly resolved relationships among leontiniids; when using equal weights, the analysis shows that Gualta cuyana is more related to the species of Anayatherium and Scarrittia canquelensis, whereas under implied weights, the new taxon is basal to other Palaeogene taxa. Gualta cuyana adds to other endemic taxa of the peculiar Deseadan assemblage from Quebrada Fiera. The new leontiniid constitutes a low percentage of fossil mammals within the Quebrada Fiera fauna, as is also true for this family in Salla (Bolivia), but in contrast with some Patagonian localities or the Brazilian Tremembé Formation where leontiniids are the best-represented mammal group.http://zoobank.org/urn:lsid:zoobank.org:pub:17749C84-4028-4FC8-A140-E1A6FE02466D

description: Cichorieae, one of the six tribes of the sub-family Cichorioideae (Asteraceae), produces a well-recognisable fenestrate pollen type. In the Mediterranean area, the significance of high percentages of Cichorieae pollen from archaeological layers is still questioned. We assessed the presence of Cichorieae as indicators of open habitats and pasturelands in current plant communities by comparing data on vegetation composition with pollen spectra from two Hellenistic sites of Basilicata (southern Italy): Difesa San Biagio in the low valley of the river Bradano and Torre di Satriano in the Lucanian Apennines. We also analysed the pollen morphology bringing to the discrimination of size classes within the fenestrate type of Cichorieae. Pollen spectra from the considered archaeological sites have low forest cover (7% on average); Asteraceae and Poaceae are prevalent; Cichorieae account to ca. 23%; coprophilous fungal spores are varied and present high concentrations. In surface soil samples collected near the sites, Cichorieae pollen is about 12%. In current vegetation types, an increasing abundance of Cichorieae was observed from salt marshes, forests and shrublands to open habitats and grasslands. This is coherent with the actual land cover around the study sites and the findings of the archaeological sample that point to an open landscape dominated by pastures and cultivated fields. Our integrated approach confirmed that today Cichorieae are common in secondary pastures and in some types of primary open habitats of southern Italy: hence, high percentages of this pollen can be considered a good indicator of these habitats even in past environment reconstructions.

description: A broad class of informationally complete symmetric measurements is introduced. It can be understood as a common generalization of symmetric, informationally complete POVMs and mutually unbiased bases. Additionally, it provides a natural way to define two new families of mutually unbiased symmetric measurement operators in any finite dimension. We show a general method of their construction, together with an example of an optimal measurement. Finally, we analyze the properties of symmetric measurements and provide applications in entropic relations and entanglement detection.

description: A search for invisible decays of the Higgs boson as well as searches for dark matter candidates, produced together with a leptonically decaying $Z$ boson, are presented. The analysis is performed using proton-proton collisions at a centre-of-mass energy of 13 TeV, delivered by the LHC, corresponding to an integrated luminosity of 139 fb$^{-1}$ and recorded by the ATLAS experiment. Assuming Standard Model cross-sections for $ZH$ production, the observed (expected) upper limit on the branching ratio of the Higgs boson to invisible particles is found to be 19% (19%) at the 95% confidence level. Exclusion limits are also set for simplified dark matter models and two-Higgs-doublet models with an additional pseudoscalar mediator.

description: Non-Fungible Tokens (NFTs) have emerged as a way to collect digital art as well as an investment vehicle. Despite having been popularized only recently, NFT markets have witnessed several high-profile (and high-value) asset sales and a tremendous growth in trading volumes over the last year. Unfortunately, these marketplaces have not yet received much security scrutiny. Instead, most academic research has focused on attacks against decentralized finance (DeFi) protocols and automated techniques to detect smart contract vulnerabilities. To the best of our knowledge, we are the first to study the market dynamics and security issues of the multi-billion dollar NFT ecosystem. In this paper, we first present a systematic overview of how the NFT ecosystem works, and we identify three major actors: marketplaces, external entities, and users. We perform an in-depth analysis of the top 8 marketplaces (ranked by transaction volume) to discover potential issues associated with such marketplaces. Many of these issues can lead to substantial financial losses. We also collected a large amount of asset and event data pertaining to the NFTs being traded in the examined marketplaces. We automatically analyze this data to understand how the entities external to the blockchain are able to interfere with NFT markets, leading to serious consequences, and quantify the malicious trading behaviors carried out by users under the cloak of anonymity.

description: In the present work we revisit the existence, stability and dynamical properties of moving discrete breathers in $β$-FPU lattices. On the existence side, we propose a numerical procedure, based on a continuation along a sequence of velocities, that allows to systematically construct breathers traveling more than one lattice site per period. On the stability side, we explore the stability spectrum of the obtained waveforms via Floquet analysis and connect it to the energy-frequency bifurcation diagrams. We illustrate in this context examples of the energy being a multivalued function of the frequency, showcasing the coexistence of different moving breathers at the same frequency. Finally, we probe the moving breather dynamics and observe how the associated instabilities change their speed, typically slowing them down over longtime simulations.

description: The germline encoding of a non-immune immunoglobulin M (IgM) molecule in mammals was experimentally documented for the first time as a result of the specifically timed ovariectomy of C57BL/10 mice. The target of this innate antibody is a trans-species developmental antigen that signifies malignancy when expressed in any non-developmental tissue. Although ovariectomy and castration result in uncontrolled and/or enhanced humoral and cellular immunity involving increased weights of the spleen and thymus with pronounced B and T cell production, the development of mercaptoethanol-sensitive, complement-binding, non-immune anti-A reactivity in murine plasma was not enhanced after an ovariectomy that was performed in C57BL/10 mice prior to the onset of puberty. This non-immune murine anti-A, which is complementary to the trans-species, syngeneic ovarian GalNAc-glycan-bearing glycolipids and distinct from the cross-reactive adaptive anti-A antibody, was strongly downregulated or did not appear in plasma of animals ovariectomized at the age of 20 days. Thus, contrary to our previous view, this reactivity is unlikely to originate from a somatic, primary immune or autoimmune response. All of the murine tissues expressed the species-specific Forssman reactivity, and further A-like structures were identified in the male and female reproductive and endodermal organs by reaction with innate human anti-A antibody, while the murine anti-A was exclusively inhibited by syngeneic ovarian glycolipids. Moreover, the early ovarian tissue, which represents a last evolutionary and/or developmental location, showed a developmental polymorphism characterized by reactivity to the lectin from Dolichos biflorus and the agglutinin from Helix pomatia indicating the functional involvement of the O-GalNAc-determined mucin-type A-like, Thomsen-Friedenreich (TF) epitope that signifies malignancy when accumulated and expressed in non-developmental tissues.
Electronic Structure and Magnetism of the Triple-layered Ruthenate Sr$_{4}$Ru$_{3}$O$_{10}$

description: We report electronic band structure calculations for Sr$_{4}$Ru$_{3}$O$_{10}$ that displays both ferromagnetic and metamagnetic behavior. The density functional calculations find the ground state to be ferromagnetic in agreement with the experiment and we find that the inclusion of Coulomb Hubbard interaction U applied to the Ru 4d states has dramatic effects on the Fermi surface, which reveal the role of Coulomb interactions and correlated many-body physics. The minority spin bands are mainly empty with Fermi surfaces in the outer areas of the Brillouin zone away from the $Γ$ point with bands that disperse steeply upward. The majority spin bands are full or nearly fully occupied and form narrow bands near the Fermi energy around the $Γ$ point, which could be the electronic origin of the metamagnetism. The results are in qualitative agreement with recent angle resolved photoemission spectroscopy (ARPES) experiments and show the need for a combined theoretical study and experimental ARPES investigation with better energy resolution to reveal the nature of the narrow bands close to the Fermi-level, which is critical for understanding the exotic magnetic properties observed in this material.

description: Cichorieae, one of the six tribes of the sub-family Cichorioideae (Asteraceae), produces a well-recognizable fenestrate pollen type. In the Mediterranean area the significance of high percentages of Cichorieae pollen from archaeological layers is still questioned. We assessed the presence of Cichorieae as indicators of open habitats and pasturelands in current plant communities, by comparing data on vegetation composition with pollen spectra from two Hellenistic sites of Basilicata (southern Italy): Difesa San Biagio in the low valley of the river Bradano, and Torre di Satriano in the Lucanian Apennines. We also analysed the pollen morphology bringing to the discrimination of size classes within the fenestrate type of Cichorieae.

description: The first efficient transformation of 4-bromomethylcoumarins and 4-bromomethylcarbostyrils to 4-formylcoumarins and 4-formylcarbostyril under aqueous conditions has been achieved by modifying the Kornblum method, resulting in excellent yield. The experimental method is very simple and economical; no further purification is required and the experimental conditions have been optimized. All the isolated compounds were characterized by infrared, NMR, and mass spectroscopy, and some of the compounds have been analyzed by single-crystal x-ray analysis.

description: В статье анализируется история кризисов банковского сектора, связанных с рынками недвижимости, в разных странах. Отмечается, что в последние десятилетия частота и доля банковских кризисов, напрямую связанных с рынками недвижимости, значительно возросла, а длительность этого типа кризисов и совокупный ущерб, наносимый ими, выше, чем ущерб от кризисов, вызванных падением цен на рынках финансовых активов. Автор делается вывод о том, что в настоящее время в России, где финансовый сектор находится на уровне развивающихся стран, вероятность «классического» кризиса банковского сектора сравнительно невысокая, однако, учитывая институциональное закрепление исключительной роли банковского сектора на рынке недвижимости, кризис возможен в среднесрочной перспективе.

description: Ruthenates provide comprehensive platform to study a plethora of novel properties, such as quantum magnetism, superconductivity and magnetic fluctuation mediated metal-insulator transition. In this article, we provide an overview of quantum mechanical phenomenology in calcium ruthenium oxide with varying compositions. While the stochiometric composition of CaRuO$_{3}$ exhibits non-Fermi liquid behavior with quasi-criticality, chemically doped compounds depict prominent signatures of quantum magnetic fluctuations at low temperature that in some cases are argued to mediate in metal-insulator transition. In the case of cobalt doped- CaRuO$_{3}$, an unusual continuum fluctuation is found to persist deep inside the glassy phase of the material. These observations reflect the richness of ruthenate research platform in the study of quantum magnetic phenomena of fundamental importance.
