title: Wie unterscheiden sich Untertitel von Fansubbern und professionellen Übersetzer*innen hinsichtlich Kulturspezifika?
Creators: name: Eibensteiner, Elisabeth
Year: 2021

description: Die vorliegende Masterarbeit beschäftigt sich mit dem Unterschied in der Übersetzung von Kulturspezifika zwischen professionellen Untertiteln und Fansubs. Konkret wurde diese Unter- suchung am Sprachenpaar Japanisch – Englisch mithilfe der ersten Staffel des Animes Natsume Yūjinchō durchgeführt. Dazu wurden die im Anime vorkommenden Kulturspezifika und deren Übersetzungen sowohl in den offiziellen Untertiteln als auch in den beiden Fansub-Versionen gesammelt und ein Übersetzungsvergleich durchgeführt. Zusätzlich wurde versucht, der Grad der Expertise aller Gruppen zu benennen. Aus dieser Arbeit geht hervor, dass professionelle Untertitel und Fansubs sehr ähnlich gestaltet werden, Fansubs jedoch tendenziell ausgangs- textorientierter ausgestaltet sind. Was die Expertise betrifft, so lässt sich bei beiden Gruppen ein hoher Grad feststellen, wobei dieser beim professionellen Team etwas ausgeprägter ist.
description: This master’s thesis investigates the difference between professional subtitles and fansubs when it comes to the translation of culture-specific items (CSI); this research was conducted using the language pair Japanese – English and the Anime Natsume Yūjinchō. For this purpose, the CSIs appearing in the Anime were collected along with the translations in the official subtitles and the Fansubs. Afterwards a translation comparison was conducted. In addition, I tried to estimate the degree of expertise the subtitle creators have. This thesis shows that professional subtitles and fansubs are rather similar although fansubs tend to be more loyal to the source text. Regarding the degree of expertise, both group show a high level although the professional team displays a higher level than the fansubbing group.

description: The paper is devoted to the study of the so-called compactly epi-Lipschitzian sets. These sets are needed for many aspects of generalized differentiation, particulary for necessary optimality conditions, stability of mathematical programming problems and calculus rules for subdifferentials and normal cones. We present general conditions under which sets defined by general constraints are compactly epi-Lipschitzian. This allows us to show how the compact epi-Lipschitzness properties behave under set intersections.
Clinical Ethics Support Services in Hospitals: Staff perceptions of their Value and the Challenge to Empirically Assess Utility and Effectiveness

description: Contemporary medicine is practiced in an environment which is defined in large part by the rapid increase in complex medical technologies, an aging and often chronically ill population, the central importance of patient autonomy, changing legal and regulatory obligations and not least, the tension between the practice of medicine versus the pragmatic and often hard-headed realities of running healthcare institutions in the modern era. This is leading to more complex decision making and many modern ethical dilemmas can be multifactorial, with no swift or simple solution. Healthcare workersnow face a wide variety of ethical challenges which they may not be adequately equipped to resolve. These may be difficult to address individually or with their immediate colleagues and can lead to moral distress, workplace conflict and professional burn out. Clinical ethics has been usefully defined as a “practical discipline which provides a structured approach for identifying, analysing and resolving ethical issues in clinical practice” (1)and the use of clinical ethics support(CES) has emerged in recent decades as a service whose objective is to assist clinicians with fair, inclusive,and transparent decision making in situations in which action is required in the face of moral uncertainty.(2)CES use is expanding globally and there is universal advocacy of its benefits, including the ability to support patient autonomy, ameliorate value conflict amongst stakeholders, alleviate moral distress, increase clinical ethics capacity in healthcare staff, and enhance organisational accountability and transparency. The majority of CES services have evolved on an ad hoc basis with corresponding heterogeneity, and this has given rise to concerns regarding the ability to empirically measure their effectiveness and utility, a challenge compounded by the almost uniform lack of regulatory oversight and quality standards. CES advocates are nonetheless striving to provide definitive quality assurance for CES services through a process of accreditation and professionalisation and this may provide a way forward for the wider introduction and mainstream acceptance of this invaluable ethical adjunct to healthcare services

description: The centriole is a ninefold symmetrical structure found at the core of centrosomes and, as a basal body, at the base of cilia, whose conserved duplication is regulated by Plk4 kinase. Plk4 phosphorylates a single serine residue at the N-terminus of Ana2 to promote Ana2's loading to the site of procentriole formation. Four conserved serines in Ana2's STAN motif are then phosphorylated by Plk4, enabling Sas6 recruitment. Crystallographic data indicate that the coiled–coiled domain of Ana2 forms a tetramer but the structure of full-length Ana2 has not been solved. Here, we have employed hydrogen–deuterium exchange coupled with mass spectrometry (HDX-MS) to uncover the conformational dynamics of Ana2 revealing the high flexibility of this protein with one rigid region. To determine the elusive nature of the interaction surfaces between Ana2 and Sas6, we have confirmed complex formation between the phosphomimetic form of Ana2 (Ana2-4D) and Sas6 in vitro and in vivo. Analysis of this complex by HDX-MS identifies short critical regions required for this interaction which lie in the C-terminal parts of both proteins. Mutational studies confirmed the relevance of these regions for the Ana2–Sas6 interaction. The Sas6 site required for Ana2 binding is distinct from the site required for Sas6 to bind Gorab and Sas6 is able to bind both these protein partners simultaneously.

GABAergic Modulation of Ethanol-Induced Motor Impairment

description: Direct or indirect pharmacological manipulation of γ-aminobutyric acid (GABA) receptor activity was examined in relation to the motor incoordinating actions of ethanol in the rat. Ethanol (1.13–3.0 g/kg i.p.) caused a dose-dependent increase in the height of aerial righting. This motor impairment was increased selectively by intracisternal injection of the GABA agonists muscimol (0.10 μg), 4,5,6,7-tetrahydroisoxazole(5,4-c) pyridin(3-ol) (1.0 μg) and GABA (1000 μg). The GABA antagonist, bicuculline (1.0 and 5.0 μg intracisternally), reduced impairment. Thus, direct manipulation of GABA receptor activity modulated motor incoordination caused by ethanol. In addition, indirect-acting GABA-mimetics, such as γ-acetylenic GABA (100 mg/kg i.p.), aminooxyacetic acid (50 mg/kg i.p.), ethanolamine-O-sulfate (250 mg/kg i.p.) and L-2,4-diaminobutyric acid (600 mg/kg i.p.) all potentiated the increase in the height of aerial righting caused by ethanol treatment. Failure of ethanol to modify the binding of [3H]muscimol to cerebral cortical membranes in vitro suggested there was no direct competition for GABA binding sites or facilitation of the binding of GABA to these sites by ethanol. Also, no simple relationship was observed between the degree of motor impairment caused by either ethanol or γ-acetylenic GABA and changes in GABA concentration in three brain areas. Although GABAergic neurons may be involved in the mechanism underlying ethanol-induced depression of motor coordination, the interaction does not involve a direct activation of GABA receptors by ethanol.
Integrating the modeling of biogeochemical cycles and energy flow
Creators: name: Rodgers, Vikki
Publisher: name: QUBES Educational Resources

description: This in-class activity challenges students to create and then integrate models of how carbon, nitrogen, water and energy all move within an ecosystem. Using 15 provided standard pools, they work independently to decide which pools are appropriate to include for their cycle and then draw and label the fluxes that connect them. Once groups have created their models, the jigsaw technique is used to critically evaluate individual models to create an agreed upon group model for each of the 4 separate cycles. Then by creating new integrated groups of 4, the students must combine their models to understand the connections between each of the cycles.

description: Kelvin probe force microscopy at normal pressure was performed by two different groups on the same Au-coated planar sample used to measure the Casimir interaction in a sphere-plane geometry. The obtained voltage distribution was used to calculate the separation dependence of the electrostatic pressure $P_{\rm res}(D)$ in the configuration of the Casimir experiments. In the calculation it was assumed that the potential distribution in the sphere has the same statistical properties as the measured one, and that there are no correlation effects on the potential distributions due to the presence of the other surface. Within this framework, and assuming that the potential distribution does not vary significantly at low pressure, the calculated $P_{\rm res}(D)$ does not explain the magnitude or the separation dependence of the difference $ΔP (D)$ between the measured Casimir pressure and the one calculated using a Drude model for the electromagnetic response of Au.

Known especially for his moral and economical theory on usury, Lessius wrote a lot of books on different matters. Because of his doctrine of the grace, he was charged with pelagianism by the theologians of the Faculty of theology of the University of Leuven. A beatification process began in the XVII century, but without success.
LO SPECCHIO DI S�. 'AMBASCIATORI', GESUITI E SOVRANI IN SCENA NEL VIAGGIO ITALIANO DI QUATTRO PRINCIPI GIAPPONESI (1585)

description: This thesis investigated how the image of Japan was exploited and adapted to the needs of 16th century Europe during the Counter-Reformation. Through the mediation of the Society of Jesus, active in the Archipelago since 1549, Japan has taken on well-defined traits in the European imaginary. On the one hand, those of a culture with which dialogue took place with simplicity on the basis of a - supposed - religious similarity, and on the other, that of a still "wild" world that was to be tamed through the religious and cultural colonization carried out by the Fathers. This idea became predominant during the 1580s, when the Jesuits conducted an embassy of four young princes to the main Italian courts to make their narration immediately identifiable: the idea of Japan and its representation would have to match perfectly. The journey, which lasted from 1582 to 1587, with the return to Japan only in 1590 due to the changed political conditions of the Archipelago, was the first moment in which the image of the "other", until then confined to the imaginary, found its reification. In a ceremonial journey in which scriptwriters, actors and spectators each played their own role, the Peninsula found itself to be the stage covered by the young princes with their double role: symbol of missionary successes and at the same time medium through which the sovereigns challenged each other with a political exploitation of welcome. The delegation can also be used to analyse the Italian society at the end of the 16th century, with a privileged focus on the mass of spectators. The citizens, in fact, had to be gratified and educated through the theatrical representation of the "different" who had to be primarily conquered from a cultural point of view.
AMPLITUHEDRA FOR PHI^3 THEORY AT TREE AND LOOP LEVEL
Creators: name: SALVATORI, GIULIO
Publisher: name: Universit� degli Studi di Milano
Year: 2019

description: In this thesis we explore a novel connection between scattering amplitudes and positive geometries, which are semi-algebraic varieties iteratively defined by the property of possessing a boundary structure which reduces into lower dimensional version of themselves. The relevance of positive geometries in physics was first discovered in the context of scattering amplitudes in N = 4 SYM and led to the definition of the Amplituhedron. An analogue structure was very recently found to tie tree level scattering amplitudes in the bi-adjoint scalar theory to the Stasheff polytope and the moduli space of Riemann surfaces of genus zero. Here we further extend this framework and show how the 1-loop integrand in bi-adjoint theory, or more generally in a planar scalar cubic theory, is connected with moduli spaces of more general Riemann surfaces. We propose hyperbolic geometry to be a natural language to study the positive geometries living in various moduli spaces, then we illustrate convex realizations of polytopes which are combinatorially equivalent to them, but live directly in the kinematical space of amplitudes and integrands. Finally, we show how to exploit these constructions to provide novel and efficient recursive formulae for both tree level amplitudes and 1-loop integrands.
Variability modes in core flows inverted from geomagnetic field models

description: The flow of liquid metal inside the Earth's core produces the geomagnetic field and its time variations. Understanding the variability of those deep currents is crucial to improve the forecast of geomagnetic field variations, which affect human spacial and aeronautic activities. Moreover, it may provide relevant information on the core dynamics. The main goal of this study is to extract and characterize the leading variability modes of core flows over centennial periods, and to assess their statistical robustness. To this end, we use flows that we invert from two geomagnetic field models (gufm1 and COV-OBS), and apply Principal Component Analysis and Singular Value Decomposition of coupled fields. The quasi geostrophic (QG) flows inverted from both geomagnetic field models show similar features. However, COV-OBS has a less energetic mean and larger time variability. The statistical significance of flow components is tested from analyses performed on subareas of the whole domain. Bootstrapping methods are also used to extract significant flow features required by both gufm1 and COV-OBS. Three main empirical circulation modes emerge, simultaneously constrained by both geomagnetic field models and expected to be robust against the particular a priori used to build them (large scale QG dynamics). Mode 1 exhibits three large vortices at medium/high latitudes, with opposite circulation under the Atlantic and the Pacific hemispheres. Mode 2 interestingly accounts for most of the variations of the Earth's core angular momentum. In this mode, the regions close to the tangent cylinder and to the equator are correlated, and oscillate with a period between 80 and 90 years. Each of these two modes is energetic enough to alter the mean flow, sometimes reinforcing the eccentric gyre, and other times breaking it up into smaller circulations. The three main circulation modes added together to the mean flow account for about 70% of the flows variability, 90% of the root mean square total velocities, and 95% of the secular variation induced by the total flows. Direct physical interpretation of the computed modes is not straightforward. Nonethe-less, similarities found between the two first modes and time/spatial features identified in different studies of core dynamics, suggest that our approach can help to pinpoint the relevant physical processes inside the core on centennial timescales.

description: Music similarity is used in many applications ranging from music recommendations to media retrieval systems. Most of music similarity metrics are computed as distances between songs on a certain multidimensional feature space. This feature space typically consists of audio descriptors that are extracted from raw audio (rhythm, tonality, spectral features). By using similarity distances we can perform a query in database, and it will return number of tracks with shortest similarity distances, thus the most similar ones. Intrinsically similarity is a subjective concept, because different listeners perceive different things as similar. In the research of music similarity it had been defined in different ways and various similarity measures had been proposed. Evaluation of those metrics is a difficult task, and is usually done via objective metrics because it requires less resources. Similarity can be measured either subjectively by using relative comparison by human subjects or objectively by using music metadata such as artist, album, genre and cultural context. Example of context usage is co-occurrence of the tracks on radio broadcasts or compilation CDs. However, subjective evaluation of most similarity metrics that are introduced in the research is usually performed with limited number of participants due to nature of experiments. In this thesis we address this problem and propose a system that can be used to perform subjective evaluation of different similarity metrics at large scale. AcousticBrainz is an online platform that aggregates music descriptors extracted from audio with globally identifiable ID for each track. We use this platform for implementation of state-of-the art similarity metrics as well as crowd-sourcing evaluation capabilities. Using user feedback as the evaluation source we are able to compare performance of various algorithms at large scale. That is achieved by providing means of similarity computation between any of millions of songs in AcousticBrainz within acceptable time. We also explore the possibility of allowing users to create their own hybrid similarity metrics and evaluate their performance in the system. The system allows to compare different metrics according to different similarity dimensions (timbre, rhythm) and calculate the performance based on subjective evaluation by users. Our results confirm the relative performance of algorithms from the previous research based on subjective evaluation and the platform shows support for much larger scale experiments and potential of being used for various practical purposes.

description: We demonstrate a spatial-imaging thermometry technique for ions in a one-dimensional Coulomb crystal by relating their imaged spatial extent along the linear radiofrequency ion trap axis to normal modes of vibration of coupled oscillators in a harmonic potential. We also use the thermal spatial spread of bright ions in the case of a two-species mixed chain to measure the center-of-mass (COM) resonance frequency of the entire chain and infer the molecular composition of the co-trapped dark ions. These non-destructive techniques create new possibilities for better understanding of sympathetic cooling in mixed-ion chains, improving few-ion mass spectrometry, and trapped-ion thermometry without requiring a scan of Doppler cooling parameters.

description: The word solidarity appears in many global health discussions and policies. It has been used to reference many reasons and ways individuals and groups come together to address global health challenges. A common suggestion in these discussions is that acts of solidarity – in the form of collaboration or support between people or organizations – harbour unique power to advance equity and social justice in and for global health. In an era marked by increasing global interconnectedness yet widening healthcare access and quality disparities, the necessity for a unified, collaborative approach to global health challenges has never been more urgent. The purpose of this qualitative study is to build an understanding of the meanings of solidarity and solidaristic practices in and for global health. Ultimately, our goal is to develop a tool, informed by the experience and expertise of global health actors, that can help those interested in collaborating across national, financial, or socio-cultural differences on global health challenges.

description: Courtyards, integral components of architectural design, hold paramount significance in shaping diverse built environments globally. In the South-South region of Nigeria, these open spaces converge cultural, social, and environmental considerations. This study systematically compares courtyards within the region, discerning shared attributes, distinctive features, and cultural nuances. Encompassing Delta, Bayelsa, Rivers, and Akwa Ibom states, the South-South region boasts a mosaic of ethnicities, enriching its architectural heritage. Courtyards stand as living testaments to the traditions, beliefs, and lifestyles of its diverse communities. Historically, courtyards in this region are foundational to architectural planning, embodying principles of community living, climate adaptation, and cultural expression. They have evolved to address environmental challenges, serving as microclimatic buffers enhancing ventilation and natural lighting. Moreover, courtyards foster social cohesion, acting as venues for communal gatherings, ceremonies, and cultural activities. While courtyards in the South-South region share a common purpose, distinct variations emerge from cultural, ethnic, and historical influences. For instance, the Ibibio, in coastal areas, integrate elements harmonizing with the maritime environment, like elevated platforms and natural materials. In contrast, the Urhobo, known for artistic craftsmanship, infuse detailed carvings and symbolic motifs, reflecting their cultural heritage. This systematic cross-cultural comparison endeavors to unveil the fundamental principles governing courtyard creation and evolution. By identifying common design elements, cultural expressions, and functional adaptations, this study provides insights into universal and context-specific aspects of courtyard design. Furthermore, it illuminates how these spaces continue to influence contemporary social dynamics, cultural practices, and environmental considerations. By scrutinizing courtyard subtleties within the South-South region, this study contributes to a broader understanding of architectural diversity and the interplay between culture, environment, and built form.

This is a re-creation and consolidation of a 2012 article written by UAlberta librarians Maria Tan and David Sulz discussing library visits while travelling. They recount some interesting anecdotes; offer a starter checklist of ideas for observations, questions, and conversations starters; pose some reflective questions to encourage enhancement of one's own librarian practice; and share a few photos. The article was originally published in three pieces (an OA journal blog blurb leading to a separate pdf with the full-text which included a Flikr link for photo sharing) but, as of 2023, all pieces had become "internet-dead" - hopefully this version is more futurised.

description: We estimate the galaxy density along lines of sight to hard extragalactic gamma-ray sources by correlating source positions on the sky with a void catalog based on the Sloan Digital Sky Survey (SDSS). Extragalactic gamma-ray sources that are detected at very high energy (VHE; E>100 GeV) or have been highlighted as VHE-emitting candidates in the Fermi Large Area Telescope hard source catalog (together referred to as "VHE-like" sources) are distributed along underdense lines of sight at the 2.4 sigma level. There is also a less suggestive correlation for the Fermi hard source population (1.7 sigma). A correlation between 10-500 GeV flux and underdense fraction along the line of sight for VHE-like and Fermi hard sources is found at 2.4 sigma and 2.6 sigma, respectively. The preference for underdense sight lines is not displayed by gamma-ray emitting galaxies within the second Fermi catalog, containing sources detected above 100 MeV, or the SDSS DR7 quasar catalog. We investigate whether this marginal correlation might be a result of lower extragalactic background light (EBL) photon density within the underdense regions and find that, even in the most extreme case of a entirely underdense sight line, the EBL photon density is only 2% less than the nominal EBL density. Translating this into gamma-ray attenuation along the line of sight for a highly attenuated source with opacity tau(E,z) ~5, we estimate that the attentuation of gamma-rays decreases no more than 10%. This decrease, although non-neglible, is unable to account for the apparent hard source correlation with underdense lines of sight.

description: It is theoretically assumed that structural members constituting a truss system are pin connected at the nodal points. However truss system joints are rarely seen being formed as ideal pinned connections. Truss members that are connected to nodal points with weld and bolts are generally partially fixed. Therefore while designing a truss system it is important that fixity ratios of the connections should be considered in computations. When analyzing a truss system having theoretically pinned connection, by using different section properties, (i.e. moment of inertia) except for section area, the results will not change. However, if the connections are not theoretically pinned, the moment of inertia of theoretically the sections will affect the results. Because of that reason, it is important that the partial fixity should be taken into account in computations. Prefabricated structures are constituted by connecting separated members that are prepared before hand. In the analysis of this kind of structures, these members are assumed to be theoretically pin connected at the nodal points. However, these connections neither pinned nor rigid connection. They are partially connected. Consequently it is also important for the prefabricated structures that the partial fixities should be taken into account in designing such a system. In this study, truss and prefabricated systems being composed of bars being partially fixed to nodal points with different ratios are investigated. Besides, how the bars having different section properties will affect the analysis is investigated. For this purpose a computer program has been developed using finite element method. It is possible to see how the displacements, end forces and stresses alter in partially fixed systems using this program.

description: We review and extend existing frameworks on modeling to develop a new framework that describes model-based reasoning in upper-division physics labs. Constructing and using models are core scientific practices that have gained significant attention within K-12 and higher education. Although modeling is a broadly applicable process, within physics education, it has been preferentially applied to the iterative development of broadly applicable principles (e.g., Newton's laws of motion in introductory mechanics). A significant feature of the new framework is that measurement tools (in addition to the physical system being studied) are subjected to the process of modeling. Think-aloud interviews were used to refine the framework and demonstrate its utility by documenting examples of model-based reasoning in the laboratory. When applied to the think-aloud interviews, the framework captures and differentiates students' model-based reasoning and helps identify areas of future research. The interviews showed how students productively applied similar facets of modeling to the physical system and measurement tools: construction, prediction, interpretation of data, identification of model limitations, and revision. Finally, we document students' challenges in explicitly articulating assumptions when constructing models of experimental systems and further challenges in model construction due to students' insufficient prior conceptual understanding. A modeling perspective reframes many of the seemingly arbitrary technical details of measurement tools and apparatus as an opportunity for authentic and engaging scientific sense-making.

description: The role of the inferior colliculus and GABAeric transmission within this structure in the development of susceptibility to sound-induced seizures in ethanol-dependent rats was examined. Ethanol-dependent rats with bilateral electrolytic lesions which destroyed approximately 50.0 ± 6.4% of the inferior colliculus failed to exhibit susceptibility to sound-induced seizures. However, comparable medial geniculate body lesions (82.7 ± 2.7% complete) did not alter wild running, slightly reduced tonus and actually increased clonus susceptibility in rats treated similarly with ethanol. As reported previously, bilateral injection of either muscimol (43–263 pmol/site) or racemic baclofen (520–1580 pmol/site) into the inferior colliculus also suppressed seizure susceptibility. Other studies in ethanol-naive animals found that bilateral microinfusion of(+)-bicuculline methoiodide (2 or 20 pmol/min for up to 5 min) into the inferior colliculus induced wild running and clonus closely resembling sound-induced seizure responses in ethanol-dependent rats. Although similar microinjections of (+)-bicuculline methiodide (0.4 pmol/min for 5 min) into the inferior colliculus did not induce seizure activity directly, an increased susceptibility to sound-induced seizures was observed. Electrolytic lesions of the medial geniculate body did not block wild running responses induced by (+)-bicuculline methiodide, but slightly reduced clonus. Five-minute infusions of picrotoxin (200 pmol/min), Ro5-3663 (2000 pmol/min), kainic acid (20 or 200 pmol/min), strychnine (2000 pmol/min) or carbachol 2000 pmol/min) into the inferior colliculus of ethanol-naive rats all induced bicuculline-like seizures. Seizures induced by bicuculline methiodide, picrotoxin or Ro5-3663 occurred within 5 min after the start of infusions. Seizures induced by non-GABAergic drugs were delayed 10 to 15 min after beginning the infusions. Finally, muscimol (263 pmol/site) administered into the inferior colliculus blocked sound-induced seizures in Uaz:AGS (S.D.) epilepsy prone rats and prevented seizures induced by bicuculline or kainic acid infused into this brain site. However, seizure responses after i.v. bicuculline infusion or maximal electroshock were not diminished by injection of this dose of muscimol into the inferior colliculus. These results suggest that adaptation in GABAergic inhibitory mechanisms in the inferior colliculus could play an important role in the genesis of sound-induced seizures in ethanol-dependent rats, although additional mechanisms involving excitatory processes may also be important.

description: With the advent of social and mobile networks, new online communitiesare being created around sustainable topics (e.g. environmental,social, community development). The phenomena, known as digital socialinnovation, generates a positive ecosystem where business and socialdevelopment enabled with new behaviors boosted by social,complementary or community currencies deployed as virtual currencieshave a great potential for competitiveness, and entrepreneurship, butalso for fostering social responsibility in Europe. This documentsummarizes actions carried out through the Vircoin2SME Europeancommunity project (social, complementary or community virtualcurrencies transfer of knowledge to SME: a new era for competitivenessand entrepreneurship) for identification of barriers and theirpossible solutions to reduce them in the context of the adoption ofsocial, complementary and virtual currencies by SMEs andconsumers. The Case Study method allowed identifying these barriersalmost at all on the basis of RES (digital currency of Belgium) andEurakos (virtual currency of Girona, Spain) complementary currenciesoperation by which the Vircoin2SME researchers had close contact. Dataanalyzed were taken through observation, being the projectresearchers’ direct users of these currencies and, the informationrecords stored in databases concerning the users’ interactions(transactions in trades associated with the RES and Eurakosnetworks).

description: Using over a million and a half extragalactic spectra we study the properties of the mysterious Diffuse Interstellar Bands (DIBs) in the Milky Way. These data provide us with an unprecedented sampling of the skies at high Galactic-latitude and low dust-column-density. We present our method, study the correlation of the equivalent width of 8 DIBs with dust extinction and with a few atomic species, and the distribution of four DIBs - 5780.6A, 5797.1A, 6204.3A, and 6613.6A - over nearly 15000 squared degrees. As previously found, DIBs strengths correlate with extinction and therefore inevitably with each other. However, we show that DIBs can exist even in dust free areas. Furthermore, we find that the DIBs correlation with dust varies significantly over the sky. DIB under- or over-densities, relative to the expectation from dust, are often spread over hundreds of square degrees. These patches are different for the four DIBs, showing that they are unlikely to originate from the same carrier, as previously suggested.

Hamiltonian circle actions on eight dimensional manifolds with minimal fixed sets

description: Consider a Hamiltonian circle action on a closed $8$-dimensional symplectic manifold $M$ with exactly five fixed points, which is the smallest possible fixed set. In their paper, L. Godinho and S. Sabatini show that if $M$ satisfies an extra "positivity condition" then the isotropy weights at the fixed points of $M$ agree with those of some linear action on $\mathbb{CP}^4$. Therefore, the (equivariant) cohomology rings and the (equivariant) Chern classes of $M$ and $\mathbb{CP}^4$ agree; in particular, $H^*(M;\mathbb{Z}) \simeq \mathbb{Z}[y]/y^5$ and $c(TM) = (1+y)^5$. In this paper, we prove that this positivity condition always holds for these manifolds. This completes the proof of the "symplectic Petrie conjecture" for Hamiltonian circle actions on on 8-dimensional closed symplectic manifolds with minimal fixed sets.

6-Hydroxydopamine Treatments Enhance Behavioral Responses to Intracerebral Microinjection of D1- and D2-Dopamine Agonists into Nucleus Accumbens and Striatum Without Changing Dopamine Antagonist Binding

description: Behavioral responses to D1 and D2-dopamine agonists are enhanced when these agonists are administered systemically to 6-hydroxydopamine (6-OHDA)-lesioned rats. In the present investigation, microinjection of SKF-38393, a D1-dopamine agonist, into the nucleus accumbens of adult rats lesioned as neonates with 6-OHDA produced a dose-related increase in locomotor activity that was enhanced markedly compared to control. LY-171555, a D2-agonist, elicited less locomotor activity than did SKF-38393 after microinjection into this site. Administration of SKF-38393 or LY-171555 into the nucleus accumbens did not increase locomotion in unlesioned rats at the doses administered to lesioned animals. In adult-6-OHDA-lesioned rats, microinjection of SKF-38393 into the nucleus accumbens also increased locomotion more than did LY-171555. As described previously, systemic administration of SKF-38393 produced little locomotion in adult-6-OHDA-lesioned rats, whereas LY-171555 produced a markedly enhanced response. Administration of SKF-38393 or LY-171555 into the caudate nucleus of neonatally and adult-6-OHDA-lesioned rats produced negligible locomotor activity, but did induce stereotypic behaviors similar to those observed after systemic treatment with these drugs. Stereotypic behaviors occurred to a greater degree in the 6-OHDA-lesioned rats than in unlesioned controls. A regional specificity for certain behaviors induced by dopamine agonist administration was observed. In spite of the enhanced behavioral responses of D1 and D2-dopamine agonists after microinjection into the brain of 6-OHDA-lesioned rats, binding of [3H]spiperone (D2-receptor antagonist ligand) and [3H]SCH 23390 (D1-receptor antagonist ligand) to tissue from striatum and nucleus accumbens was not altered significantly. In contrast to this lack of change in binding characteristics in 6-OHDA-lesioned rats, blockade of dopaminergic transmission with haloperidol treatment caused an elevation of [3H]spiperone binding sites in striatum without affecting affinity for the site. However, chronic haloperidol treatment did not alter significantly [3H]SCH 23390 binding to striatal membranes. These latter findings suggest that chronic dopamine receptor blockade need not produce the same adaptive mechanisms as destruction of dopamine-containing neurons. Thus, a change in receptor characteristics as measured by dopamine antagonist binding does not account for the behavioral supersensitivity observed after D1- and D2-dopamine agonist administration to neonatally or adult-6-OHDA-treated rats.

description: From the perspective of AdS/CFT the Pomeron is identified with a Reggeized Graviton, while the Odderons correspond to Reggeized anti-symmetric $AdS_5$ Kalb-Ramond tensor-fields. In this paper, we consider the strong coupling expansion of the dimension of the leading twist operators dual to these Regge trajectories, $Δ(j)$, to determine its analytic continuation in $j$ beyond the diffusion limit. In particular, we compute the strong coupling expansion of the intercept to order $λ^{-3}$, where $λ$ is the t'Hooft coupling, for both the Pomeron, which is $C=+1$ crossing-even, and the "Odderons", which are the leading $C=-1$ crossing-odd Regge singularities. We discuss the spectral curves of the class of single-trace operators to which these string modes couple.

Viability of the matter bounce scenario in Loop Quantum Cosmology for general potentials

description: We consider the matter bounce scenario in Loop Quantum Cosmology (LQC) for physical potentials that at early times provide a nearly matter dominated Universe in the contracting phase, having a reheating mechanism in the expanding phase, i.e., being able to release the energy of the scalar field creating particles that thermalize in order to match with the hot Friedmann Universe, and finally at late times leading to the current cosmic acceleration. For these models, numerically solving the dynamical equations we have seen that the teleparallel version of LQC leads to theoretical results that fit well with current observational data. More precisely, in teleparallel LQC there is a set of solutions which leads to theoretical results that match correctly with last BICEP2 data, and there is another set whose theoretical results fit well with {\it Planck's} experimental data. On the other hand, in holonomy corrected LQC the theoretical value of the tensor/scalar ratio is smaller than in teleparallel LQC, which means that there is always a set of solutions that matches with {\it Planck's} data, but for some potentials BICEP2 experimental results disfavours holonomy corrected LQC.
