“Santa mozzarella!”: The construction of Italianness in Luca (Disney and Pixar, 2021)
Creators: name: Passa, Davide
Publisher: name: Wydawnictwo Uniwersytetu Jana Kochanowskiego w Kielcach
Year: 2022

description: Eighty-one years after Pinocchio (1940), Walt Disney and Pixar are back with a new animated film set entirely in Italy, Luca (2021). It is a coming-of-age story based on a deep friendship between two sea monster boys and a human girl from Portorosso, an imaginary sea coastal town in the Cinque Terre (Liguria), in the nostalgic mid-1950s. This study intends to investigate the construction of Italianness in the film on the visual and acoustic levels. First, this article will briefly examine the visual representation of Italian people, objects and traditions that contribute to the overall construction of fictional Italianness in the film. Then, the fictional language used to characterise the inhabitants of Portorosso to distinguish them from the sea monsters will be examined in more detail; this will be done by analysing code-switching instances, where Italianisms will be included in four different categories. Unlike Pinocchio, Luca’s producers have created an artificial code that is of particular interest to researchers in the field of Sociolinguistics and Audiovisual Studies. This study will mainly focus on the construction of identity and Kozloff ’s functions of film dialogues. In the final sections of the article, which will analyse code-switching, Brown and Levinson’s impoliteness theory will also be addressed.

description: Malta’s Constitution declares both Maltese, the indigenous language, and English as the country’s official languages. Maltese is also the national language and since 2002 it was accorded official status in the European Union. Maltese is accordingly given more importance in Malta, a miniscule island with a population of slightly more than half a million people. This study reports on the findings of a scientifically representative study among 500 University of Malta students on their language use when using social media platforms. It provides data on the actual languages used in messages sent by the students themselves. This paper examines the different contexts in which English and Maltese are used on the social media platforms. It compares how the participants spontaneously use either language in different social media forms of communication. The study concludes that rather than a process of displacement of Maltese what is happening is differential usage through which Maltese is predominant in informal settings, while English is mainly used in more formal settings.

description: The current and complex framework for the study of languages, especially English, offers key insights into not only language change, but also the role of neuroscience in such change. In this study, which is part of a wider project, our aim is to trace the diachronic development of English through the textual analysis of various Bible translations, in order to verify its discursive identity. For this purpose, the 50 chapters of Genesis have been analysed in the following versions of the Bible: the Wycliffite, the Tyndale, the King James, the New King James, the 1881 English Revised Version, and the 1982 New King James Version. Several linguistic parameters have been compared through manual counting and statistical comparison. The results have confirmed our hypothesis that a deep modification of linguistic identity has occurred over the centuries.

description: L’émergence des big data entraîne l’apparition d’un nouveau paradigme en termes de production de savoir. Celui-ci est le résultat (1) des caractéristiques de ces données (volumineuses, en flux continu, de formats variés, avec une distance importante entre la donnée brute et le signal), (2) des méthodes particulières d’analyse de ces données, davantage inductives, (3) d’une aura d’objectivité naturelle qui les accompagne parfois,(4) de leur valorisation au sein de l’imaginaire montant de la smart city qui promeut une action publique dynamique. Pour l’étude de la mobilité, les big data sont complémentaires aux données traditionnelles : elles ont une meilleure exhaustivité et une granulosité spatio-temporelle plus fine mais elles accusent un déficit d’attributs. Leur usage se heurte toutefois à divers obstacles (représentativité, respect de la vie privée, compétences techniques, propriété d’acteurs privés) qui imposent notamment une validation régulière et faussent la comparabilité dans le temps. Nous recommandons aux administrations de prendre langue avec les opérateurs privés pour peser sur le processus de production de ces données.

description: The visualization of future generation Wireless Communication Network WCN redirects the presumption of onward innovations, the fulfillment of user demands in the form of high data rates, energy efficiency, low latency, and long-range services. To content these demands, various technologies such as massive MIMO Multiple Input Multiple Output, UDN Ultra Dense Network, spectrum sharing, D2D Device to Device communication were improvised in the next generation WCN. In comparison to previous technologies, these technologies exhibit flat architecture, the involvement of clouds in the network, centralized architecture incorporating small cells which creates vulnerable breaches initiating menaces to the security of the network. The half-duplex attack is another threat to the WCN, where the resource spoofing mechanism is attained in the downlink phase of D2D communication. Instead of triggering an attack on both uplink and downlink, solely downlink is targeted by the attacker. This scheme allows the reduced failed attempt rate of the attacker as compared to the conventional attacks. The analysis is determined on the basis of Poissons distribution to determine the probability of failed attempts of half duplex attack in contrast to a full duplex attack

Diese Methode bietet große Vorteile (z. B. Bestätigung/Ausschluss einer Übertragung bei Ausbrüchen, Unterscheidung Rückfall/Reinfektion, Unterscheidung primäre/erworbene Arzneimittelresistenz). Im Epidemiologischen Bulletin 24/2019 werden die Ergebnisse einer Bestandsaufnahme zur Nutzung molekularer Typisierungsergebnisse von Gesundheitsämtern vorgestellt. Es wurde eine hohe Variabilität bei der Verwendung einer molekularen Typisierung für die Tuberkulose-Überwachung unter Gesundheitsämtern in Deutschland beobachtet. Rund ein Viertel der Befragten nutzt bereits die molekulare Typisierung für ihre Routinearbeit. Mit der Novellierung des Infektionsschutzgesetzes vom Juli 2017 wurde eine gesetzliche Grundlage zur Integration und Übermittlung der Ergebnisse der molekularen Typisierung gemeinsam mit den Meldedaten geschaffen.
Pronouns in Dickinson’s poetryas a means of constructing a poetic self
Creators: name: Vezzosi, Letizia
Publisher: name: Wydawnictwo Uniwersytetu Jana Kochanowskiego w Kielcach
Year: 2022

description: Poetic language is often defined by its apparent violations of ordinary language rules because of its usage of ‘unacceptable’ or at least very unusual constructions, under the label of ‘poetic licence’. This is also true for Emily Dickinson’s language, characterised as obscure, elliptical or ambiguous. The present paper is an attempt to show how the ‘poetic forms’ are nothing but an extreme exploitation of everyday language resources which can sometimes appear to be ambiguous or obscure only as a side effect of their extra-contextualisation. The case in point is the analysis of Dickinson’s use of personal pronouns, which is not agrammatical, but resorts to the pragmatic and topicality conditions overruling the semantic rules of gender agreement, thus building her view and feeling of herself as a woman and a poet.
The representation of the concept of flirtation and coquetry in English: An analysis based on the Historical Thesaurus of the Oxford English Dictionary
Creators: name: Landmann, Julia
Publisher: name: Wydawnictwo Uniwersytetu Jana Kochanowskiego w Kielcach
Year: 2022

description: Love is as old as humanity itself. Therefore, it is not surprising that over the centuries, a great variety of words and expressions related to this subject have been coined. The Historical Thesaurus of the Oxford English Dictionary (henceforth referred to as the HTOED) is a rich resource for those who intend to study this field from a linguistic point of view. The present analysis sets out to examine an essential domain which is related to the field of love. It will examine a comprehensive sample of 79 nouns referring to flirtation and coquetry. This has so far been neglected in current research. Besides the HTOED, media such as the OED Online and corpora of present-day English including the BNC, the COCA, the Movie Corpus, the TV Corpus and the Soap Corpus will be employed, in order to get a rounded picture of the etymological origin, semantics and contextual uses, including informal usage, of the sample of words under scrutiny from a historical perspective. It thus goes far beyond the scope of previous research on this area.
Effect of mass loss due to stellar winds on the formation of supermassive black hole seeds in dense nuclear star clusters

description: The observations of high redshifts quasars at $z\gtrsim 6$ have revealed that supermassive black holes (SMBHs) of mass $\sim 10^9\,\mathrm{M_{\odot}}$ were already in place within the first $\sim$ Gyr after the Big Bang. Supermassive stars (SMSs) with masses $10^{3-5}\,\mathrm{M_{\odot}}$ are potential seeds for these observed SMBHs. A possible formation channel of these SMSs is the interplay of gas accretion and runaway stellar collisions inside dense nuclear star clusters (NSCs). However, mass loss due to stellar winds could be an important limitation for the formation of the SMSs and affect the final mass. In this paper, we study the effect of mass loss driven by stellar winds on the formation and evolution of SMSs in dense NSCs using idealised N-body simulations. Considering different accretion scenarios, we have studied the effect of the mass loss rates over a wide range of metallicities $Z_\ast=[.001-1]\mathrm{Z_{\odot}}$ and Eddington factors $f_{\rm Edd}=L_\ast/L_{\mathrm{Edd}}=0.5,0.7,\,\&\, 0.9$. For a high accretion rate of $10^{-4}\,\mathrm{M_{\odot}yr^{-1}}$, SMSs with masses $\gtrsim 10^3\MSun$ could be formed even in a high metallicity environment. For a lower accretion rate of $10^{-5}\,\mathrm{M_{\odot}yr^{-1}}$, SMSs of masses $\sim 10^{3-4}\,\mathrm{M_{\odot}}$ can be formed for all adopted values of $Z_\ast$ and $f_{\rm Edd}$, except for $Z_\ast=\mathrm{Z_{\odot}}$ and $f_{\rm Edd}=0.7$ or 0.9. For Eddington accretion, SMSs of masses $\sim 10^3\,\mathrm{M_{\odot}}$ can be formed in low metallicity environments with $Z_\ast\lesssim 0.01\mathrm{Z_{\odot}}$. The most massive SMSs of masses $\sim 10^5\,\mathrm{M_{\odot}}$ can be formed for Bondi-Hoyle accretion in environments with $Z_\ast \lesssim 0.5\mathrm{Z_{\odot}}$.

description: Recent work has suggested a surprising new upper bound on the lifetime of de Sitter vacua in string theory. The bound is parametrically longer than the Hubble time but parametrically shorter than the recurrence time. We investigate whether the bound is satisfied in a particular class of de Sitter solutions, the KKLT vacua. Despite the freedom to make the supersymmetry breaking scale exponentially small, which naively would lead to extremely stable vacua, we find that the lifetime is always less than about exp(10^(22)) Hubble times, in agreement with the proposed bound.

Measuring eccentricity in binary black-hole initial data

description: Initial data for evolving black-hole binaries can be constructed via many techniques, and can represent a wide range of physical scenarios. However, because of the way that different schemes parameterize the physical aspects of a configuration, it is not alway clear what a given set of initial data actually represents. This is especially important for quasiequilibrium data constructed using the conformal thin-sandwich approach. Most initial-data studies have focused on identifying data sets that represent binaries in quasi-circular orbits. In this paper, we consider initial-data sets representing equal-mass black holes binaries in eccentric orbits. We will show that effective-potential techniques can be used to calibrate initial data for black-hole binaries in eccentric orbits. We will also examine several different approaches, including post-Newtonian diagnostics, for measuring the eccentricity of an orbit. Finally, we propose the use of the ``Komar-mass difference'' as a useful, invariant means of parameterizing the eccentricity of relativistic orbits.

A philosophical analysis of scientific meanings of aging in psychosocial gerontology
Creators: name: Kenyon, Gary M.
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation is concerned with the problem of scientific assumptions as it relates to research in gerontology. There are three major areas emphasized in the thesis. First, there is a consideration of the epistemological conditions that give rise to the problem of assumptions and meanings in science. Secondly, a number of different ways of addressing this issue are discussed and an alternative Hermeneutic approach is explicated. This approach constitutes a particular kind of philosophical analysis and is suggested by the insights of Hans Gadamer. Finally, on the basis of the Hermeneutic approach, two major characterizations of research on adult and gerontological intellectual and social competence are identified, namely, a restricted and an expanded picture. In addition, these two characterizations are further clarified by means of a discussion of the contrasting ontological orientations that are presupposed in the restricted and correspondingly, in the expanded picture. The overall purpose of the thesis is to show that a particular kind of philosophical inquiry assists in the integration of disparate forms of research in psychosocial gerontology. In addition, this procedure provides conceptual support for a different understanding of various phenomena associated with human aging that is emerging in the field, namely, the expanded picture.

description: We have carried out N-body simulations for rotating star clusters with equal mass and compared the results with Fokker-Planck models. These two different approaches are found to produce fairly similar results, although there are some differences with regard to the detailed aspects. We confirmed the acceleration of the core collapse of a cluster due to an initial non-zero angular momentum and found a similar evolutionary trend in the central density and velocity dispersion in both simulations. The degree of acceleration depends on the initial angular momentum. Angular momentum is being lost from the cluster due to the evaporation of stars with a large angular momentum on a relaxation time scale.

description: Many recent observational studies have concluded that planetary systems commonly exist in multiple-star systems. At least ~20%, and presumably a larger fraction of the known extrasolar planetary systems are associated with one or more stellar companions. These stellar companions normally exist at large distances from the planetary systems (typical projected binary separations are on the orders 100-10000AU) and are often faint (ranging from F to T spectral types). Yet, secular cyclic angular momentum exchange with these distant stellar companions can significantly alter the orbital configuration of the planets around the primaries. One of the most interesting and fairly common outcomes seen in numerical simulations is the opening of a large mutual inclination angle between the planetary orbits, forced by differential nodal precessions caused by the binary companion. The growth of the mutual inclination angle between planetary orbits induces additional large-amplitude eccentricity oscillations of the inner planet due to the quadrupole gravitational perturbation by the outer planet. This eccentricity oscillation may eventually result in the orbital decay of the inner planet through tidal friction, as previously proposed as Kozai migration or Kozai cycles with tidal friction (KCTF). This orbital decay mechanism induced by the binary perturbation and subsequent tidal dissipation may stand as an alternative formation channel for close-in extrasolar planets.

Mandela’s Favourite African Folktales

Publisher: name: Università degli  Studi di Milano

description: In this essay I would like to examine the selection of African tales that Nelson Mandela took care to leave as heritage to the future generations, not only to children, and not only to African children. The fact that a political leader, ex freedom fighter and political prisoner dedicated his time to the collection and editing of stories from all over the African continent to be addressed to new readers as simple entertainment or as educational tools clearly testifies to the great humanity, culture, and open mindedness of one of the most important men of our times. In his most recent autobiographical writing Conversations With Myself, Mandela claimed his double affiliation to both his own indigenous culture as well as to western culture. Moreover, he recalled with affection a dear pastime of his childhood:

After supper we would listen enthralled to my mother and sometimes my aunt telling us stories, legends, myths and fables which have come down from countless generations, and all of which tended to stimulate the imagination and contained some valuable moral lesson. (p. 10)

Thus, it is not surprising that such a charismatic public figure, as Mandela has been, was also interested in- and worried about- the future survival of a cluster of traditional folktales with their lively, specific and “valuable moral lesson”. It is my intention to verify if there might be a dialogue between the western tradition of folktales where animals are protagonists and speak as anthropomorphic figures and the facets of the African traditions and cultures from which Mandela draws inspiration. Among the critical tools on this topic, Tess Cosslett’s Talking Animals in British Children’s Fiction (2006) seems to provide a useful starting point, together with the latest studies in the volume Dall’ABC a Harry Potter (2011), among others. Moreover, aspects of “orature” will be discussed with reference to the stories chosen by Nelson Mandela. Finally, an attempt will be made to connect these types of animal tales to works of figurative art, particularly paintings, by African artists, which might share the same moral message and which might trigger similar narratives.

description: Surface waves, named here as Dyakonov-Tamm waves, can exist at the planar interface of an isotropic dielectric material and a chiral sculptured thin film (STF). Due to the periodic nonhomogeneity of a chiral STF, the range of the refractive index of the isotropic material is smaller but the range of the propagation direction in the interface plane is much larger, in comparison to those for the existence of Dyakonov waves at the planar interface of an isotropic dielectric material and a columnar thin film.
The Capsula eburnea in several Middle English witnesses

Year: 2022

description: Medieval treatises containing predictions to recognise the signs of death were based on works written by Hippocrates or attributed to him. In the case of the Capsula eburnea, the original text was written in Greek and translated into Latin in the Middle Ages. The Latin translations circulated widely in different versions: a translation from Greek between the fifth and the seventh centuries and a later translation from Arabic in the late twelfth century. During the late Middle English period, they were translated into English, among other vernacular languages. The present article aims to compare and collate four fifteenth-century prognostic treatises in Middle English with their possible Latin exemplars. The analysis of the witnesses will shed light on the shadowy landscape of pseudo-Hippocratic prognostic texts in Middle English and will contribute to trace the Latin sources of these Middle English witnesses.
Scale-up studies on the culture of brine shrimp Artemia fed with rice bran
Creators: name: Platon, Rolando R.
Publisher: name: University of British Columbia
Year: 2010

description: The effects of water movement or agitation on the biological performance of planktonic organisms under intensive culture have been rarely studied quantitatively. Stagnation or minimum values are considered important in the problem of scale-up based on optimum conditions. Near stagnation, inadequate water movement brings about undesirable effects, e.g. accumulation of metabolites, uneven distribution of feed and low dissolved oxygen concentration. An important mechanism associated with water movement at these conditions is the oxygenation process which defines the oxygen transfer rate from the gas to the water. Experiments were conducted using potable water to determine the overall oxygen mass transfer coefficient in two types of container geometries; a) cylindri-conical tank and b) oblong-shaped center- partitioned raceway. For each type of container, three geometrically similar sizes were investigated with scale ratio of approximately 1:2:3.5. Agitation was induced by the introduction of air into the system. General correlations for both tank geometries were obtained from experimental data and were expressed in terms of the operating and geometric parameters. The correlations are in the form of dimensionless groups (Froude and Reynolds numbers) making them appropriate for scale-up estimates. The general correlations for the overall oxygen mass transfer coefficient were subsequently used to provide the scaling equations to define the operating parameters in different sizes of containers for the culture of brine shrimp in sea water fed with rice bran. The high correlation coefficient obtained for the relationship between total brine shrimp biomass production and the overall mass transfer coefficient applicable to different sizes of both the cylindri-conical tank and the raceway indicates that the overall oxygen mass transfer coefficient is an effective scale-up criterion in brine shrimp culture.

We also comment on the implications of our results for heavy quarkonium bound states in the quark gluon plasma.

description: 5G NR (New Radio) incorporates concepts of novel technologies such as spectrum sharing, D2D communication, UDN, and massive MIMO. However, providing security and identifying the security threats to these technologies occupies the prime concern. This paper intends to provide an ample survey of security issues and their countermeasures encompassed in the technologies of 5G NR. Further, security concerns of each technology are defined mathematically. Thereby defining the impact on the factors of security. Moreover, a methodology is developed in which the influence on security due to artificially generated rain and artificially generated dust on the wireless communication network is studied. By doing so, an attacking scenario is identified, where a half-duplex attack in D2D communication is attained. Half-duplex attack specifies the attack solely on the downlink to spoof the allocated resources, with reduced miss-rate. Thus, ultra-reliable and adequate advances are required to be addressed to remove the obstacles that create a hindrance in achieving the secured and authenticated communicating network

description: We analyse the positions of RR Lyrae stars in the central region of the Milky Way. In addition to the overall bar shape detected previously, we find evidence for a peanut shaped structure, in form of overdensities near $\ell=-2$ deg and $1$ deg at $b\sim-3.5$ deg. The corresponding physical distance between the two peaks of the peanut is $\sim0.7$ kpc, significantly shorter than that found from near-IR images (3.3 kpc) and red-clump stars. Qualitatively this is expected from `fractionation' of bar orbits, which we demonstrate to be matched in a simulation of an inside-out growing disc subsequently forming a bar.

description: Adjoint methods can speed up stellarator optimisation by providing gradient information more efficiently compared to finite-difference evaluations. Adjoint methods are herein applied to vacuum magnetic fields, with objective functions targeting quasisymmetry and a rotational transform value on a surface. To measure quasisymmetry, a novel way of evaluating approximate flux coordinates on a single flux surface without the assumption of a neighbourhood of flux surfaces is proposed. The shape gradients obtained from the adjoint formalism are evaluated numerically and verified against finite-difference evaluations.

description: We have estimated the CMB variance from the three-year WMAP data, finding a value which is significantly lower than the one expected from Gaussian simulations using the WMAP best-fit cosmological model, at a significance level of 98.7 per cent. This result is even more prominent if we consider only the north ecliptic hemisphere (99.8 per cent). Different analyses have been performed in order to identify a possible origin for this anomaly. In particular we have studied the behaviour of single radiometers and single year data as well as the effect of residual foregrounds and 1/f noise, finding that none of these possibilities can explain the low value of the variance. We have also tested the effect of varying the cosmological parameters, finding that the estimated CMB variance tends to favour higher values of $n_s$ than the one of the WMAP best-fit model. In addition, we have also tested the consistency between the estimated CMB variance and the actual measured CMB power spectrum of the WMAP data, finding a strong discrepancy. A possible interpretation of this result could be a deviation from Gaussianity and/or isotropy of the CMB.

description: The Hubble constant can be constrained using the time delays between multiple images of gravitationally lensed sources. In some notable cases, typical lensing analyses assuming isothermal galaxy density profiles produce low values for the Hubble constant, inconsistent with the result of the HST Key Project (72 +- 8 km/s/Mpc). Possible systematics in the values of the Hubble constant derived from galaxy lensing systems can result from a number of factors, e.g. neglect of environmental effects, assumption of isothermality, or contamination by line-of-sight structures. One additional potentially important factor is the triaxial structure of the lensing galaxy halo; most lens models account for halo shape simply by perturbing the projected spherical lensing potential, an approximation that is often necessary but that is inadequate at the levels of triaxiality predicted in the CDM paradigm. To quantify the potential error introduced by this assumption in estimates of the Hubble parameter, we strongly lens a distant galaxy through a sample of triaxial softened isothermal halos and use an MCMC method to constrain the lensing halo profile and the Hubble parameter from the resulting multiple image systems. We explore the major degeneracies between the Hubble parameter and several parameters of the lensing model, finding that without a way to accurately break these degeneracies accurate estimates of the Hubble parameter are not possible. Crucially, we find that triaxiality does not significantly bias estimates of the Hubble constant, and offer an analytic explanation for this behaviour in the case of isothermal profiles. Neglected triaxial halo shape cannot contribute to the low Hubble constant values derived in a number of galaxy lens systems.

description: The recent robust and homogeneous analysis of the world's supernova distance-redshift data, together with cosmic microwave background and baryon acoustic oscillation data, provides a powerful tool for constraining cosmological models. Here we examine particular classes of scalar field, modified gravity, and phenomenological models to assess whether they are consistent with observations even when their behavior deviates from the cosmological constant Lambda. Some models have tension with the data, while others survive only by approaching the cosmological constant, and a couple are statistically favored over LCDM. Dark energy described by two equation of state parameters has considerable phase space to avoid Lambda and next generation data will be required to constrain such physics.

description: This paper describes our approach to the Toxic Spans Detection problem (SemEval-2021 Task 5). We propose BERToxic, a system that fine-tunes a pre-trained BERT model to locate toxic text spans in a given text and utilizes additional post-processing steps to refine the boundaries. The post-processing steps involve (1) labeling character offsets between consecutive toxic tokens as toxic and (2) assigning a toxic label to words that have at least one token labeled as toxic. Through experiments, we show that these two post-processing steps improve the performance of our model by 4.16% on the test set. We also studied the effects of data augmentation and ensemble modeling strategies on our system. Our system significantly outperformed the provided baseline and achieved an F1-score of 0.683, placing Lone Pine in the 17th place out of 91 teams in the competition. Our code is made available at https://github.com/Yakoob-Khan/Toxic-Spans-Detection

description: Topological edge states exhibit dissipationless transport and electrically-driven topological phase transitions, making them ideal for next-generation transistors that are not constrained by Moore's law. Nevertheless, their dispersion has never been probed and is often assumed to be simply linear, without any rigorous justification. Here we determine the non-linear electrical response of topological edge states in the ballistic regime and demonstrate the way this response ascertains the presence of symmetry breaking terms in the edge dispersion, such as deviations from non-linearity and tilted spin quantization axes. The non-linear response stems from discontinuities in the band occupation on either side of a Zeeman gap, and its direction is set by the spin orientation with respect to the Zeeman field. We determine the edge dispersion for several classes of topological materials and discuss experimental measurement.

description: Helical edge states of two-dimensional topological insulators show a gap in the density of states (DOS) and suppressed conductance in the presence of ordered magnetic impurities. Here we will consider the dynamical effects on the DOS and transmission when the magnetic impurities are driven periodically. Using the Floquet formalism and Green's functions, the system properties are studied as a function of the driving frequency and the potential energy contribution of the impurities. We see that increasing the potential part closes the DOS gap for all driving regimes. The transmission gap is also closed, showing a pronounced asymmetry as a function of energy. These features indicate that the dynamical transport properties could yield valuable information about the magnetic impurities.

Chaotic scattering with direct processes: A generalization of Poisson's kernel for non-unitary scattering matrices

description: The problem of chaotic scattering in presence of direct processes or prompt responses is mapped via a transformation to the case of scattering in absence of such processes for non-unitary scattering matrices, \tilde S. In the absence of prompt responses, \tilde S is uniformly distributed according to its invariant measure in the space of \tilde S matrices with zero average, < \tilde S > =0. In the presence of direct processes, the distribution of \tilde S is non-uniform and it is characterized by the average < \tilde S > (\neq 0). In contrast to the case of unitary matrices S, where the invariant measures of S for chaotic scattering with and without direct processes are related through the well known Poisson kernel, here we show that for non-unitary scattering matrices the invariant measures are related by the Poisson kernel squared. Our results are relevant to situations where flux conservation is not satisfied. For example, transport experiments in chaotic systems, where gains or losses are present, like microwave chaotic cavities or graphs, and acoustic or elastic resonators.

description: The myth of Tannhäuser, the legendary minnesinger of the 13th century, stands out among the most significant mythological motives of European art. His image received many interpretations by authors of different eras and nationalities and reflected trends in art, morality and religion over the centuries. The reception of Tannhäuser myth in the Russian and German poetry of Yuri Klen not only absorbed the current trends in reading this myth in the literature of modernism, but also demonstrated the individuality of the author’s approach. The article deals with the peculiarities of Yuri Klen’s interpretation of Tannhäuser mythologeme, the specificity of the evolution of the image and the originality of the poet’s interpretation of the myth in the context of European art.

description: We show how two topologically distinct spaces - the Kahler K3 x T^2 and the non-Kahler T^2 bundle over K3 - can be smoothly connected in heterotic string theory. The transition occurs when the base K3 is deformed to the T^4/Z_2 orbifold limit. The orbifold theory can be mapped via duality to M-theory on K3 x K3 where the transition corresponds to an exchange of the two K3's.

description: With the evolution of WCN (Wireless communication networks), the absolute fulfillment of security occupies the fundamental concern. In view of security, we have identified another research direction based on the attenuation impact of rain in WCN. An approach is initiated by an eavesdropper in which a secure communication environment is degraded by generating Artificial Rain (AR), which creates an abatement in the secrecy rate, and the cybersecurity gets compromised. By doing so, an attacking scenario is perceived, in which an intruder models a Half-Duplex (HD) attack. Half-Duplex specifies the attack on the downlink instead of targeting both uplink and downlink. This allows the attacker to alleviate the miss-rate of the attacking attempts. The layout for the HD attack is explained using RRC (Radio Resource Control)-setup. Further, we have determined and examined the performance parameters such as secrecy rate, energy efficiency, miss-rate, sensitivity in the presence of AR. Further comparison of rural and urban scenarios in the presence and absence of AR is carried out concerning the variation in secrecy rate with respect to the millimeter-wave frequencies and distance. Lastly, the methodology of the HD attack is simulated, revealing that the HD attack maintains a low miss rate with improved performance as compared to the performance and miss-rate attained by the full-duplex attack
