description: The hypothesis that strange quark matter is the true ground state of matter has been investigated for almost four decades, but only a few works have explored the dynamics of binary systems of quark stars. This is partly due to the numerical challenges that need to be faced when modelling the large discontinuities at the surface of these stars. We here present a novel technique in which the EOS of a quark star is suitably rescaled to produce a smooth change of the specific enthalpy across a very thin crust. The introduction of the crust has been carefully tested by considering the oscillation properties of isolated quark stars, showing that the response of the simulated quark stars matches accurately the perturbative predictions. Using this technique, we have carried out the first fully general-relativistic simulations of the merger of quark-star binaries finding several important differences between quark-star binaries and hadronic-star binaries with the same mass and comparable tidal deformability. In particular, we find that dynamical mass loss is significantly suppressed in quark-star binaries. In addition, quark-star binaries have merger and post-merger frequencies that obey the same quasi-universal relations derived from hadron stars if expressed in terms of the tidal deformability, but not when expressed in terms of the average stellar compactness. Hence, it may be difficult to distinguish the two classes of stars if no information on the stellar radius is available. Finally, differences are found in the distributions in velocity and entropy of the ejected matter, for which quark-stars have much smaller tails. Whether these differences in the ejected matter will leave an imprint in the electromagnetic counterpart and nucleosynthetic yields remains unclear, calling for the construction of an accurate model for the evaporation of the ejected quarks into nucleons.

description: The aim of this thesis is to examine the notion of honour in marginality by the study of two different literary genres: the romantic drama of Victor Hugo and the opera libretto. In particular, the study is based on a comparison of three of Victor Hugo’s plays: Hernani, Le Roi s’amuse and Lucrèce Borgia and their respective libretti: Ernani and Rigoletto, written by the librettist Francesco Maria Piave, and Lucrezia Borgia, written by the librettist Felice Romani. An anthropological approach, based on the studies of the French philosophers Michel Foucault and George Bataille and on those of Italian Giorgio Agamben, allows to reflect whether the sentiment of honor can also exist in people who live on the borders of society, like the bandit Hernani, the commander Gennaro and the jester Triboulet, or whether it is exclusively a prerogative of a social sovereignty justified by the law. Finally, this thesis explores whether honour can be considered as a moral or merely as a social condition. A literary approach demonstrates how the libretto, while retaining particularities of the genre and of the culture in which it was written, expresses the dramatic message with the same intensity and the same aim of the writer, so contributing to the transmission of the social and cultural changes of the Romantic period.
description: Σκοπός αυτής της εργασίας είναι να εξετάσει την έννοια της τιμής στο πλαίσιο της περιθωριοποίησης μέσα από τη μελέτη δύο διαφορετικών λογοτεχνικών ειδών: το ρομαντικό δράμα του Βίκτωρος Ουγκώ και το λιμπρέτο της όπερας. Συγκεκριμένα,, η μελέτη βασίζεται στη σύγκριση τριών έργων του Βίκτωρος Ουγκώ: Hernani, Le roi s’amusse και Lucrèce Borgia και των αντίστοιχων λιμπρέτων τους: Ernani and Rigoletto του λιμπρετίστα Francesco Maria Piave και Lucrezia Borgia του λιμπρετίστα Felice Romani. Μια ανθρωπολογική προσέγγιση που βασίζεται στις μελέτες των Γάλλων φιλοσόφων Michel Foucault και Georges Bataille και στις μελέτες του Giorgio Agamben αποδεικνύει κατά πόσο το αίσθημα της τιμής μπορεί να χαρακτηρίζει και ανθρώπους που ζούνε στο περιθώριο της κοινωνίας, όπως ο ληστής Hernani, ο αρχηγός Gennaro και γελωτοποιός Triboulet, ή αν αποτελεί απoκλειστικά προνόμιο μιας κοινωνικής κυριαρχίας που δικαιολογείται από το νόμο. Εν κατακλείδι, η εργασία αυτή αναδεικνύει πώς το λιμπρέττο, ενώ διατηρεί τις ιδιαιτερότητες του είδους του και του πολιτισμικού πλαισίου στο οποίο γράφτηκε, εκφράζει το δραματικό του μήνυμα με την ίδια ένταση και κρατώντας τις προθέσεις του συγγραφέα συμβάλοντας έτσι στη μετάδοση των κοινωνικών και πολιτιστικών αλλαγών της Ρομαντικής Περιόδου.

description: We present the first results of the VLBA Imaging and Polarimetry Survey (VIPS), a 5 GHz VLBI survey of 1,127 sources with flat radio spectra. Through automated data reduction and imaging routines, we have produced publicly available I, Q, and U images and have detected polarized flux density from 37% of the sources. We have also developed an algorithm to use each source's I image to automatically classify it as a point-like source, a core-jet, a compact symmetric object (CSO) candidate, or a complex source. The mean ratio of the polarized to total 5 GHz flux density for VIPS sources with detected polarized flux density ranges from 1% to 20% with a median value of about 5%. We have also found significant evidence that the directions of the jets in core-jet systems tend to be perpendicular to the electric vector position angles (EVPAs). The data is consistent with a scenario in which ~24% of the polarized core-jets have EVPAs that are anti-aligned with the directions of their jet components and which have a substantial amount of Faraday rotation. In addition to these initial results, plans for future follow-up observations are discussed.

Expression profiles of DEGs under different salinity contrasts are shown for eight clusters in leaves and roots. DEGs in leaves are significantly enriched in three clusters (LC8, LC4, LC5), whereas DEGs in roots are significantly enriched in RC1 and RC5. In each cluster, the black line represents the expression level (means of log10(FPKM value + 1)) of all enriched genes, the error bars represent standard deviations. A permutation test was used to evaluate the significance of differences. The clusters with statistically significant difference in the number of DEGs are marked with triple (P-value < 0.01) asterisks. The observed and expected (only significant clusters) numbers of genes belonging to each cluster are labeled on the top of each cluster.

description: Most ultra-luminous X-ray sources (ULXs) are now thought to be powered by stellar-mass compact objects accreting at super-Eddington rates. While the discovery of evolutionary cycles have marked a breakthrough in our understanding of the accretion flow changes in the sub-Eddington regime in Galactic Black Hole Binaries, their evidence in the super-Eddington regime remained elusive. However, recent circumstantial evidence had hinted the presence of a recurrent evolutionary cycle in two archetypal ULXs: Holmberg II X-1 and NGC 5204 X-1. Here we build on our previous work and exploit the long-term high-cadence monitoring of Swift-XRT in order to provide evidence of the evolutionary cycle in these two sources and investigate the main physical parameters inducing their spectral transitions. We study the long-term evolution of both sources using hardness-intensity diagrams (HID) and by means of Lomb-Scargle periodograms and Gaussian processes modelling to look for periodic variability. We show that both sources follow a recurrent evolutionary pattern in the HID that can be characterized by the hard ultraluminous (HUL) and soft ultraluminous (SUL) spectral regimes, and a third state with characteristics similar to the supersoft ultraluminous (SSUL) state. The transitions between the soft states seem aperiodic, as revealed by timing analysis of the light curve of Holmberg II X-1, albeit further investigation is warranted. The light curve of NGC 5204 X-1 shows a periodicity of $\sim$ 200 days, possibly associated with the duration of the evolutionary cycle. We support a scenario in which the spectral changes from HUL to SUL are due to a periodic increase of the mass-transfer rate and subsequent narrowing of the opening angle of the supercritical funnel. The narrower funnel, combined with stochastic variability imprinted by the wind, might explain the SUL--SSUL spectral changes.

description: The present dissertation studies the path of two contemporary poets, Manolis Anagnostakis and Paul Eluard. The comparative study of their poetry questions how each poet experienced war and defeat after having struggled practically and morally for a revolution that has never been accomplished. The dissertation is divided in two chapters: the first one examines the work and the political ideology of each poet in the respective political and social background; the second and larger one covers the analysis of their poems through the concepts of expectation, time, life and death.

Το κύριο ερώτημα που εξετάζεται μέσω της σύγκρισης των δύο έργων είναι το πώς οι δύο ποιητές αντιμετωπίζουν πρώτα τον πόλεμο κι έπειτα την ήττα, έχοντας ήδη αγωνιστεί όχι μόνο ιδεολογικά αλλά και στην πράξη, για ιδανικά που ποτέ δεν δικαιώθηκαν. Η εργασία χωρίζεται σε δύο ενότητες: στην πρώτη παρουσιάζονται η πολιτική ιδεολογία και το έργο του κάθε ποιητή στο αντίστοιχο πολιτικό και κοινωνικό υπόβαθρο. Τη δεύτερη και μεγαλύτερη ενότητα καλύπτει η ανάλυση ποιημάτων τους μέσα από τις έννοιες της προσδοκίας, του χρόνου, της ζωής και του θανάτου.

description: Exile in literature or more exactly migrant literature has always raised critics from ancient time to now on especially in the cultural interaction. The book is then composed of three autonomous and distinct parts which have a common link: migration in mist and hybrid families. Marie Ndiaye, in her last novel calls it the enigma of the confrontation even the complexity of what she defines as: rootedness/uprootness. The right balance between homeland and host country customs should also be found. But adaptation to culture and host country way of life is necessary for the migrant That diversity appears in the migrant literary novels where the world, this big family, through Interaction of several cultures gives a global touch to those novels. After the investigations we had made we realized that the issues developped in the novel entirely show the experience of french authors from migration. This makes us think over a better definition of migrant literature in France.
description: Η εξορία στη λογοτεχνία, για τη ακρίβεια η μεταναστευτική λογοτεχνία, έχει δεχθεί κριτική από τα παλαιότερα χρόνια μέχρι σήμερα κυρίως σε ό,τι αφορά στην πολιτιστική αλληλεπίδραση. Το βιβλίο αποτελείται από τρία αυτόνομα και διακριτά μέρη με ένα κοινό σημείο: migration in mist and hybrid families. Η Marie Ndiaye στο τελευταίο της βιβλίο αποκαλεί αυτό το φαινόμενο ‘αίνιγμα της αντιπαράθεσης’ : ρίζες/ξεριζωμός. Είναι αναγκαίο να επιτευχθεί η σωστή ισορροπία ανάμεσα στην πατρίδα και τη χώρα υποδοχής. Αλλά η προσαρμογή στην κουλτούρα και τον τρόπο ζωής της χώρας υποδοχής είναι απαραίτητα για το μετανάστη. Η ποικιλομορφία αυτή είναι φανερή στη μεταναστευτική λογοτεχνία στα οποία ο κόσμος, αυτή η μεγάλη οικογένεια, μέσω της αλληλεπίδρασης διαφορετικών πολιτισμών, προσδίδει έναν χαρακτήρια σφαιρικό στα έργα αυτά. Η έρευνα που έγινε έδειξε ότι τα θέματα που αναπτύσσονται στο έργο αναδεικνύουν πλήρως την εμπειρία της εξορίας των Γάλλων συγγραφέων. Αυτό δημιουργεί την ανάγκη ενός καλύτερου ορισμού της μεταναστευτικής λογοτεχνίας της Γαλλίας.

description: Radiative decays ϕ\toηπ^0γand ϕ\toπ^0π^0γare studied assuming that these decays are caused through the intermediate a_0(980)γand f_0(980)γstates, respectively. Fitting the experimental data of the ηπ^0 and π^0π^0 invariant mass spectrum in the decays ϕ\toηπ^0γand π^0π^0γ, it is shown that the processes ϕ\to a_0γand ϕ\to f_0γare dominated by the K^+K^- loop interaction rather than the contact ϕa_0(f_0)γone both for the non-derivative and derivative SPP coupling. The experimental data of Γ[ϕ\to f_0γ]/Γ[ϕ\to a_0γ] predicts that g_{f_0K\bar{K}}/g_{a_0K\bar{K}} \sim 2. Considering the effects of the mixing between low mass scalar qq\bar{q}\bar{q} states and high mass scalar q\bar{q} states to these coupling constants g_{f_0K\bar{K}} and g_{a_0K\bar{K}}, one suggests that the mixing is rather large.

description: Bacteria and their bacteriophages are the most abundant, widespread and diverse groups of biological entities on the planet. In an attempt to understand how the interactions between bacteria, virulent phages and temperate phages might affect the diversity of these groups, we developed a novel stochastic network model for examining the co-evolution of these ecologies. In our approach, nodes represent whole species or strains of bacteria or phages, rather than individuals, with "speciation" and extinction modelled by duplication and removal of nodes. Phage-bacteria links represent host-parasite relationships and temperate-virulent phage links denote prophage-encoded resistance. The effect of horizontal transfer of genetic information between strains was also included in the dynamical rules. The observed networks evolved in a highly dynamic fashion but the ecosystems were prone to collapse (one or more entire groups going extinct). Diversity could be stably maintained in the model only if the probability of speciation was independent of the diversity. Such an effect could be achieved in real ecosystems if the speciation rate is primarily set by the availability of ecological niches.

description: We possess convincing experimental evidence for the fact that the real photon has non-trivial parton structure. On the other hand, interactions of the cosmic microwave background photons with high energy particles propagating through the Universe play an important role in astrophysics. In this context, to invoke the parton content could be convenient for calculations of the probabilities of different processes involving these photons. As an example, the cross section of inclusive resonant $W^+$ boson production in the reaction $νγ\to W^+X$ is calculated by using the parton language. Neutrino--photon deep inelastic scattering is considered.
description: 4 pages, 2 figures. The spin states of the initial particles in the reaction $\nu\gamma\to W^+X$ are correctly treated. As a result, the corresponding cross section becomes two times greater than the one from the previous version. Some changes in the text
Search for W$γ$ resonances in proton-proton collisions at $\sqrt{s} =$ 13 TeV using hadronic decays of Lorentz-boosted W bosons
Creators: name: CMS Collaboration

Year: 2021
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A search for W$γ$ resonances in the mass range between 0.7 and 6.0 TeV is presented. The W boson is reconstructed via its hadronic decays, with the final-state products forming a single large-radius jet, owing to a high Lorentz boost of the W boson. The search is based on proton-proton collision data at $\sqrt{s} =$ 13 TeV, corresponding to an integrated luminosity of 137 fb$^{-1}$, collected with the CMS detector at the LHC in 2016-2018. The W$γ$ mass spectrum is parameterized with a smoothly falling background function and examined for the presence of resonance-like signals. No significant excess above the predicted background is observed. Model-specific upper limits at 95% confidence level on the product of the cross section and branching fraction to the W$γ$ channel are set. Limits for narrow resonances and for resonances with an intrinsic width equal to 5% of their mass, for spin-0 and spin-1 hypotheses, range between 0.17 fb at 6.0 TeV and 55 fb at 0.7 TeV. These are the most restrictive limits to date on the existence of such resonances over a large range of probed masses. In specific heavy scalar (vector) triplet benchmark models, narrow resonances with masses between 0.75 (1.15) and 1.40 (1.36) TeV are excluded for a range of model parameters. Model-independent limits on the product of the cross section, signal acceptance, and branching fraction to the W$γ$ channel are set for minimum W$γ$ mass thresholds between 1.5 and 8.0 TeV.

description: It is quite plausible that color superconductivity occurs in the inner regions of neutron stars. At the same time, it is known that strong magnetic fields exist in the interior of these compact objects. In this paper we discuss some important effects that can occur in the color superconducting core of compact stars due to the presence of the stars' magnetic field. In particular, we consider the modification of the gluon dynamics for a color superconductor with three massless quark flavors in the presence of an external magnetic field. We show that the long-range component of the external magnetic field that penetrates the color-flavor locked phase produces an instability for field values larger than the charged gluons' Meissner mass. As a consequence, the ground state is restructured forming a vortex state characterized by the condensation of charged gluons and the creation of magnetic flux tubes. In the vortex state the magnetic field outside the flux tubes is equal to the applied one, while inside the tubes its strength increases by an amount that depends on the amplitude of the gluon condensate. This paramagnetic behavior of the color superconductor can be relevant for the physics of compact stars.

Relevance weighted smoothing and a new bootstrap method
Creators: name: Hu, Feifang
Publisher: name: University of British Columbia
Year: 2009

description: This thesis addresses two quite different topics. First, we consider several relevance weighted smoothing methods for relevant sample information. This topic can be viewed as a generalization of nonparametric smoothing. Second, we propose a new bootstrap method which is based on estimating functions. A statistical problem usually begins with an unknown object of inferential of interest. About this unknown object, we may have three types of information (classified in this thesis): direct information, exact sample information and relevant sample information. Almost all classical statistical theory is about direct information and exact sample in formation. In many cases, relevant sample information is available and useful. But there is no systematic theory about relevant sample information. The problem of this thesis is to extract “the relevant information” contained in the relevant samples. The general methods have been developed under three different lines of approach ( parametric, nonparametric and semiparametric approach). In the parametric approach, we propose the idea of relevance weighted likelihood (REWL). For the nonparametric approach, we develop our theory based on the relevance weighted empirical distribution function (REWED). In the semiparametric approach, the relevance weighted estimating functions are used to extract “relevant information” from relevant samples. From asymptotic results, we find that these proposed methods have many desirable properties. We apply these proposed methods as well as some adjusted methods to generalized smoothing problems. Theoretical results as well as simulation results show our methods to be promising. We also present a new bootstrap method. It has computational and theoretical advan tages over conventional bootstrap methods when the data obtain from non-identically distributed observables. And it differs from conventional methods in that it resamples components of an estimating function rather than the data themselves.

Казалось бы, в условиях самоизоляции и удаленной работы, когда людям не на чем и не за чем сидеть, бизнес по продаже и производству офисных кресел и регулируемых столов должен развиваться как никогда. Но несмотря на это, сфера эргономики рабочего пространства также столкнулась с рядом вызовов, с которыми необходимо справиться бизнесу, адаптируясь к новым условиям. В данной статье рассматриваются причины парадокса угрозы экономической безопасности российских компаний, занятых в области эргономики рабочего места, независимо от роста спроса на офисные кресла и столы по причине разрешенной удаленной работы и самоизоляции во время коронавирусной пандемии.

description: The interaction between individuals in biological populations, dilute components of chemical systems, or particles transported by turbulent flows depends critically on their contact statistics. This work clarifies those statistics under the simplifying assumptions that the underlying motions approximate a Brownian random walk and that the particles can be treated as noninteracting. We measure the contact-interval (also called the waiting-time or inter-arrival-time), contact-count, and contact-duration distributions in populations of individuals undergoing noninteracting continuous-space-time random walks on a periodic two-dimensional plane (a torus), as functions of the population number density, walker radius, and random-walk step size. The contact-interval is exponentially distributed for times longer than the mean-free-collision time but not for times shorter than that, and the contact duration distribution is strongly peak at the ballistic-crossing time for head-on collisions, when the ballistic-crossing time is short compared to the mean step duration. While successive contacts between individuals are independent, the probability of repeat contact decreases with time after a previous contact. This leads to a negative duration dependence of the waiting-time interval and over dispersion of the contact-count probability density function for all time intervals. The paper demonstrates that for populations of small particles (walker radius small compared to the mean-separation or random-walk step size) the mean-free-collision interval, the ballistic-crossing time, and the random-walk-step duration can be used to construct temporal scalings which allow for common waiting-time, contact-count, and contact-duration distributions across different populations. Semi-analytic approximations for both the waiting-time and contact-duration distributions are also presented.

description: Σκοπός της μεταπτυχιακής διατριβής ήταν η θεωρητική μελέτη με βάση τη θεωρία των συναρτησιακών της πυκνότητας (DFT), του μηχανισμού της αντίδρασης του Ν-ακετυλο-1,2-δις-τριφλουορομεθανοσουλφοναμιδίου με την R-1 και S-1-φαινυλαιθυλαμίνη τόσο σε διάλυμα τολουολίου όσο και διμεθυλοφορμαμιδίου (DMF). Η μελέτη αυτή μπορεί να βοηθήσει καθοριστικά στην ερμηνεία της στερεοεκλεκτικότητας που παρατηρείται στη συγκεκριμένη αντίδραση, αλλά κυρίως συνεισφέρει στη μελέτη του μηχανισμού σύνθεσης διαφόρων φυσικών προϊόντων, επειδή στη διάρκειά της συντίθεται ένας πεπτιδικός δεσμός. Με τη βοήθεια κατάλληλων συναρτησιακών της DFT καταλήξαμε στις δομές που απαρτίζουν το ενεργειακό προφίλ της αντίδρασης και προσδιορίσαμε τις ενεργειακές διαφορές μεταξύ τους. Τα συμπεράσματά μας: α) επαληθεύουν τα διαθέσιμα πειραματικά των ίδιων ενώσεων, και β) αποδίδουν την αδυναμία αντίδρασης των R και S στερεοϊσομερών της φαινυλαιθυλαμίνης στους δύο διαλύτες τόσο στις μεγάλες τιμές της ενέργειας ενεργοποίησης που προσδιορίστηκαν όσο και στην παρουσία ισχυρά ενεργειακά σταθεροποιημένων διμερών των αντιδρώντων.
description: The aim of the present postgraduate thesis was the theoretical study of the reaction mechanism of N-acetyl-1,2-bis-trifluoromethanesulfonamide with R-1 and S-1-phenylethylamine, based on the density functional theory (DFT), in both toluene and dimethylformamide solutions. The contribution of this study to the interpretation of the stereoselectivity observed in this reaction is decisive, but mainly it contributes to the study of natural products synthesis mechanism, due to a newly formed peptide bond in the final products. Through the appropriate DFT functionals, we determined the structures involved in the reaction profile, as well as their energy differences along the potential energy surface of the reaction. The conclusions of our study: a) verify the available experimental data, and b) attribute the inability of both R and S stereoisomers of 1-phenylethylamine to both the high activation energy values calculated and the presence of strongly energetically stabilized reaction dimers.

description: We propose a reformulation of general relativity by making the Abelian decomposition of Einstein's theory. Based on the view that Einstein's theory can be interpreted as a gauge theory of Lorentz group, we decompose the Einstein's gravitational connection (the gauge potential of Lorentz group $\vGm_μ$) into the restricted connection made of the potential of the maximal Abelian subgroup $H$ of Lorentz group $G$ and the valence connection made of $G/H$ part of the potential which transforms covariantly under Lorentz group. With this decomposition we show that the Einstein's theory can be decomposed into the restricted part made of the restricted connection which has the full Lorentz gauge invariance and the valence part made of the valence connection which plays the role of gravitational source of the restricted gravity. We show that there are two different Abelian decomposition of Einstein's theory, because Lorentz group has two maximal Abelian subgroups. In this decomposition the role of the space-time metric $g_\mn$ is replaced by a four-index metric tensor $\vg_\mn$ which transforms covariantly under the Lorentz group, and the metric-compatibility condition $\nabla_αg_\mn=0$ of the connection is replaced by the gauge covariant condition $D_μ\vg^\mn$ which tells that $\vg_\mn$ is invariant under the parallel transport along the $\pro_μ$-direction defined by $\vGm_μ$. We discuss the physical implications of the Abelian decomposition. In particular, we argue that the decomposition implies the existence of a restricted theory of gravitation which has the full general invariance but has less physical degrees of freedom.

description: Экономическая повестка Германии в период председательства в Совете ЕС реализовалась в одни из самых трудных периодов европейского хозяйственного пространства. В статье рассматриваются итоги основных экономических инициатив Германии. Они связаны с политикой продолжения структурных изменений и использование возможностей, инициированным Европейским зеленым курсом и процессом цифровизации. Подчеркивается, что много инициатив было направлено на укрепление единого внутреннего рынка, который опорой устойчивости европейской экономики факторов усиления взаимозависимости стран. Коронокризис ускорил переход к зеленой, цифровой экономике. Меры структурной политики компенсировали ухудшение экономической конъюнктуры и повышали конкурентоспособность европейских регионов для новых вызовов. В этом контексте председательство Германии прагматично ставило цель укрепить Европу как инновационный центр цифровой и экологической трансформации и шаг за шагом добиваться стратегической экономической автономии континента в ключевых хозяйственно-политических вопросах.

description: We study the ground state of a $d$--dimensional Ising model with both long range (dipole--like) and nearest neighbor ferromagnetic (FM) interactions. The long range interaction is equal to $r^{-p}$, $p>d$, while the FM interaction has strength $J$. If $p>d+1$ and $J$ is large enough the ground state is FM, while if $d1$ the ground state has a series of transitions from an antiferromagnetic state of period 2 to $2h$--periodic states of blocks of sizes $h$ with alternating sign, the size $h$ growing when the FM interaction strength $J$ is increased (a generalization of this result to the case $0
