"In Nature's Dress." The Anthropocene, Talking Nature and the Poetry of Margaret Cavendish
Creators: name: Mattana, Alessio
Publisher: name: RiCOGNIZIONI. Rivista di Lingue e Letterature straniere e Culture moderne
Year: 2023

description: This paper examines a selection of poems on nature by Margaret Cavendish, an English poet and natural philosopher active in the mid-seventeenth century. Cavendish’s conception of nature was “organicist”, meaning that all creatures – humans, animals and plants alike – share similar abilities in terms of feeling and reasoning. In this essay, Cavendish’s organicism will be discussed as the philosophical framework of her collection Poems, and Fancies (1653), especially those poems in which beasts, plants or nature herself engage in dialogue with human beings about their relationship with the environment. It will be argued that Cavendish’s choice to give voice to nature works as a fictional strategy to help readers imagine an alternative idea of nature, one different to that of nature as resource that was becoming increasingly widespread with the advent of early modern science. In the final section, it will finally be suggested that reading Cavendish’s poetry through the lens of post-humanism can contribute to present-day discussions on the Anthropocene.

Natural Inflation: the status after WMAP 3-year data

description: The model of Natural Inflation is examined in light of recent 3-year data from the Wilkinson Microwave Anisotropy Probe and shown to provide a good fit. The inflaton potential is naturally flat due to shift symmetries, and in the simplest version takes the form $V(ϕ) = Λ^4 [1 \pm \cos(Nϕ/f)]$. The model agrees with WMAP3 measurements as long as $f > 0.7 m_{Pl}$ (where $m_{Pl} = 1.22 \times 10^{19}$GeV) and $Λ\sim m_{GUT}$. The running of the scalar spectral index is shown to be small -- an order of magnitude below the sensitivity of WMAP3. The location of the field in the potential when perturbations on observable scales are produced is examined; for $f > 5 m_{Pl}$, the relevant part of the potential is indistinguishable from a quadratic, yet has the advantage that the required flatness is well-motivated. Depending on the value of $f$, the model falls into the large field ($f \ge 1.5 m_{Pl}$) or small field ($f < 1.5 m_{Pl}$) classification scheme that has been applied to inflation models. Natural inflation provides a good fit to WMAP3 data.

description: Direct numerical simulations are performed to contrast turbulent boundary layers over a concave wall without and with free-stream turbulence. Adverse pressure gradient near the onset of curvature leads to sharp decrease in skin friction and intermittent separation. The presence of free-stream turbulence reduces the probability of reverse flow, accelerates the recovery of the boundary layer in the downstream zero-pressure gradient region, and leads to a sustained and appreciable increase in the skin friction. The forcing also promotes the amplification of coherent Görtler structures in the logarithmic layer of the curved-wall boundary layer. Statistically, the spanwise and wall-normal Reynolds stresses intensify and the radial distance between their peaks increases downstream as the Görtler structures expand. The Reynolds shear stress coefficient also increases in the logarithmic layer in contrast to a decrease when a flat-plate boundary layer is exposed to free-stream turbulence. In addition, the more coherent and energetic roll motions in the forced flow promote mixing of free-stream and boundary-layer fluids, where the former is seen more often deep within the buffer layer.

description: We review results on the scaling of the optimal path length in random networks with weighted links or nodes. In strong disorder we find that the length of the optimal path increases dramatically compared to the known small world result for the minimum distance. For Erdős-Rényi (ER) and scale free networks (SF), with parameter $λ$ ($λ>3$), we find that the small-world nature is destroyed. We also find numerically that for weak disorder the length of the optimal path scales logaritmically with the size of the networks studied. We also review the transition between the strong and weak disorder regimes in the scaling properties of the length of the optimal path for ER and SF networks and for a general distribution of weights, and suggest that for any distribution of weigths, the distribution of optimal path lengths has a universal form which is controlled by the scaling parameter $Z=\ell_{\infty}/A$ where $A$ plays the role of the disorder strength, and $\ell_{\infty}$ is the length of the optimal path in strong disorder. The relation for $A$ is derived analytically and supported by numerical simulations. We then study the minimum spanning tree (MST) and show that it is composed of percolation clusters, which we regard as "super-nodes", connected by a scale-free tree. We furthermore show that the MST can be partitioned into two distinct components. One component the {\it superhighways}, for which the nodes with high centrality dominate, corresponds to the largest cluster at the percolation threshold which is a subset of the MST. In the other component, {\it roads}, low centrality nodes dominate. We demonstrate the significance identifying the superhighways by showing that one can improve significantly the global transport by improving a very small fraction of the network.

description: Occasional short switches to creaky voice are common in spoken discourse of numerous languages without either the speakers or the recipients being highly aware of them, which is the reason the creaky voice phenomenon is, under the best of conditions, considered by them as a phenomenon of going down to very low or even the lowest part of their vocal range. In this paper, it is proposed that creaky voice when it comes to spoken conversations in German and Croatian serves as a short-term mechanism for a relatively delayed formation of completional prosodic patterns that, until the manifestation of the creaky voice, to that point also comprise, among other features, accents with rising or flat tonal components. Such completional patterns may accompany utterances that immediately precede the decision to allow the interlocutor to take turn, utterances that do not immediately precede it, or utterances that immediately precede a change in the speech act by the same speaker. The creaky voice, however, sometimes occurs in other sequences, i.e., within prosodic patterns without the accents bearing rising or flat components of the tonal movement, which is, however, considered as a result of an unintentional ''slipping'' into creaky voice due to the speaker's to low value of the subglottal pressure at the given moment.

description: We extend rotation theory of circle maps to tiling spaces. Specifically, we consider a 1-dimensional tiling space $Ω$ with finite local complexity and study self-maps $F$ that are homotopic to the identity and whose displacements are strongly pattern equivariant (sPE). In place of the familiar rotation number we define a cohomology class $[μ]$. We prove existence and uniqueness results for this class, develop a notion of irrationality, and prove an analogue of Poncaré's Theorem: If $[μ]$ is irrational, then $F$ is semi-conjugate to uniform translation on a space $Ω_μ$ of tilings that is homeomorphic to $Ω$. In such cases, $F$ is semi-conjugate to uniform translation on $Ω$ itself if and only if $[μ]$ lies in a certain subspace of the first cohomology group of $Ω$.

description: We present the properties of a cosmic superstring network in the scenario of flux compactification. An infinite family of strings, the (p,q)-strings, are allowed to exist. The flux compactification leads to a string tension that is periodic in 'p'. Monopoles, appearing here as beads on a string, are formed in certain interactions in such networks. This allows bare strings to become cosmic necklaces. We study network evolution in this scenario, outlining what conditions are necessary to reach a cosmologically viable scaling solution. We also analyze the physics of the beads on a cosmic necklace, and present general conditions for which they will be cosmologically safe, leaving the network's scaling undisturbed. In particular, we find that a large average loop size is sufficient for the beads to be cosmologically safe. Finally, we argue that loop formation will promote a scaling solution for the interbead distance in some situations.

The Visual-Digital Storytelling in Current Migration Narratives

Year: 2023

description: Using W. J. Thomas Mitchell’s concept of the “pictorial turn” as a starting point, this paper assesses the impact of the digital world and new media on the body of current migration narratives within the field of anglophone postcolonial literature. In a culture dominated by images, new media, particularly the Internet, have increasingly complemented written language as the primary means of conveying storytelling. In regard to migration narratives, as it happened at the dawn of cinematography when the human face attained a multidimensional, visual and emotional focus, this shift in the messenger has conferred a digital life to the human face itself. Given this new media reality, the human face is now able to communicate simultaneously across distances, across time and to a wider audience. This quality, referred to as “facialization” by Thomas Macho, enables individuals to take a predominant role as real-life protagonists in their own real-life stories engendering in return an online community. Furthermore, as put forth by Hilde C. Stephansen, this online community also takes a stand against the mainstream narrative of present-day migrations and directs attention to marginalized human beings prevented from entering Western societies. In this paper, these real-life stories are explored in the visual-digital storytelling by Chimamanda Ngozi Adichie of her experience as a migrant; by Reni Eddo-Lodge as a descendant of earlier migrants; by Lucy Popescu as an activist working for the publishing industry as well as by activists engaged in the Refugee Tales Statement. This visual-digital production of migration narratives and their consequent availability also render the human rights issues facing stateless persons pressing and immediate.

description: We study the long range part of the $Λ$-hyperon optical potential in nuclei using Quantum Many Body techniques and flavor-SU(3) Chiral Lagrangians as starting point. More precisely, we study the contributions to the $Λ$-hyperon optical potential due to the long-range two-pion exchange, with $Σ$ and $Σ^*$ baryons in the internal baryonic lines and considering Nh and $Δ$h excitations. We also consider the contribution to the spin-orbit potentials that comes out from these terms. Our results support a natural explanation of the smallness of the $Λ$-nuclear spin-orbit interaction and shows the importance of the $Σ^*$ and $Δ$ degrees of freedom for the hyperon-nucleus interactions.

description: The masses of the ground and isomeric states in $^{124,125}$Ag have been measured using the phase-imaging ion-cyclotron-resonance technique at the JYFLTRAP double Penning trap mass spectrometer. The ground states of $^{124}$Ag and $^{125}$Ag were found to be 30(250) keV and 250(430) keV less bound but 36 and 110 times more precise than in the Atomic Mass Evaluation 2020, respectively. The excitation energy of $^{124}$Ag$^{m}$, ${E_x = 188.2(25)}$ keV, was determined for the first time. The new precise mass values have been utilised to study the evolution of nuclear structure via two-neutron separation energies. The impact on the astrophysical rapid neutron capture process has been investigated via neutron-capture reaction rate calculations. The precision measurements indicate a more linear trend in two-neutron separation energies and reduce the mass-related uncertainties for the neutron-capture rate of $^{124}$Ag$(n,γ)^{125}$Ag by a factor of around 100. The new mass values also improve the mass of $^{123}$Pd, previously measured using $^{124}$Ag as a reference.

description: We study the prospects for constraining dark energy at very high redshift with the Sandage-Loeb (SL) test - a measurement of the evolution of cosmic redshift obtained by taking quasar spectra at sufficiently separated epochs. This test is unique in its coverage of the ``redshift desert'', corresponding roughly to redshifts between 2 and 5, where other dark energy probes are unable to provide useful information about the cosmic expansion history. Extremely large telescopes planned for construction in the near future, with ultra high resolution spectrographs (such as the proposed CODEX), will indeed be able to measure cosmic redshift variations of quasar Lyman-alpha absorption lines over a period as short as ten years. We find that these measurements can constrain non-standard and dynamical dark energy models with high significance and in a redshift range not accessible with future dark energy surveys. As the cosmic signal increases linearly with time, measurements made over several decades by a generation of patient cosmologists may provide definitive constraints on the expansion history in the era that follows the dark ages but precedes the time when standard candles and rulers come into existence.

description: The similarities between the intercomprehensive approach to language teaching and inclusive language education have been studied for some years, but there is currently no speculative research or laboratory experiments that can validate their convergences.

During the a.y. 2021/2022 members of the ELICom research group of the University of Parma started an experimental research at the Language Center in a course of intercomprehension between Romance languages. This course, open to all, saw among the participants a large number of students with special learning needs and allowed to implement a pilot study aimed at detecting some aspects considered particularly significant.

First results suggest that the intercomprehensive approach may have positive effects on the psycho-cognitive profile of this type of learner and that bimodal input is effective for all kind of students.

description: In this paper, as a generalization to content algebras, we introduce amount algebras. Similar to the Anderson-Badawi $ω_{R[X]}(I[X])=ω_R(I)$ conjecture, we prove that under some conditions, the formula $ω_B(I^ε)=ω_R(I)$ holds for some amount $R$-algebras $B$ and some ideals $I$ of $R$, where $ω_R(I)$ is the smallest positive integer $n$ that the ideal $I$ of $R$ is $n$-absorbing. A corollary to the mentioned formula is that if, for example, $R$ is a Prüfer domain or a torsion-free valuation ring and $I$ is a radical ideal of $R$, then $ω_{R[][X]]}(I[[X]])=ω_R(I)$.

description: Nanostructured plasmonic metal systems are known to enhance greatly variety of radiative and nonradiative optical processes, both linear and nonlinear, which are due to the interaction of an electron in a molecule or semiconductor with the enhanced local optical field of the surface plasmons. Principally different are numerous many-body phenomena that are due to the Coulomb interaction between charged particles: carriers (electrons and holes) and ions. These include carrier-carrier or carrier-ion scattering, energy and momentum transfer (including the drag effect), thermal equilibration, exciton formation, impact ionization, Auger effects, etc. It is not widely recognized that these and other many-body effects can also be modified and enhanced by the surface-plasmon local fields. A special but extremely important class of such many-body phenomena is constituted by chemical reactions at metal surfaces, including catalytic reactions. Here, we propose a general and powerful theory of the plasmonic enhancement of the many-body phenomena resulting in a closed expression for the surface plasmon-dressed Coulomb interaction. We illustrate this theory by computing this dressed interaction explicitly for an important example of metal-dielectric nanoshells, which exhibits a reach resonant behavior in both the magnitude and phase. This interaction is used to describe the nanoplasmonic-enhanced Foerster energy transfer between nanocrystal quantum dots in the proximity of a plasmonic nanoshell. Catalysis at nanostructured metal surfaces, nonlocal carrier scattering and surface-enhanced Raman scattering are discussed among other effects and applications where the nanoplasmonic renormalization of the Coulomb interaction may be of principal importance.
Modern Resignation to Postmodern Despair in Don Delillo’s ‘Cosmopolis’ and ‘Falling Man’
Creators: name: Tonelli, Maria Ilaria

description: This article investigates how DeLillo depicts the impact of 9/11 in Cosmopolis and Falling Man through the antagonistic (intratextual) and oppositional (intertextual) connections between their characters, and then proves the importance of counter-narrative as a means to survive the encounter with communal and private tragedies. To this end, the articles provides a complementary analysis of DeLillo’s characterizations and stylistic choices in Cosmopolis and Falling Man, reading the novels through the lens of DeLillo’s essay “In the Ruins of the Future” (2001), Jean Baudrillard’s Simulacra and Simulation (1981) and “The Spirit of Terrorism” (2002), Jacques Derrida’s Writing and Difference (1967), Slavoj Žižek’s Welcome to the Desert of the Real (2002), and Søren Kierkegaard’s Either/Or (1843). While the two novels offer a Postmodern sublimation of the defining features and challenges of the post-9/11 lost sense of reality, I argue that Kierkegaard’s Modern philosophy is the key to a comprehensive reading of them, as it offers the theoretical ground for a metaphorical leap of faith that grants access to “a higher realm” of acceptance, overcoming the feeling of bewilderment and alienation in the aftermath of the late modern age.

Estimating the nuclear saturation parameter via low-mass neutron star asteroseismology

description: We examine the fundamental ($f$-) and the 1st pressure ($p_1$-) mode frequencies in gravitational waves from cold neutron stars constructed with various unified realistic equations of state. With the calculated frequencies, we derive the empirical formulae for the $f$- and $p_1$-mode frequencies, $f_f$ and $f_{p_1}$, as a function of the square root of the stellar average density and the parameter ($η$), which is a combination of the nuclear saturation parameters. With our empirical formulae, we show that by simultaneously observing the $f$- and $p_1$-mode gravitational waves, when $1.5\lesssim f_{p_1}/f_f\lesssim 2.5$ (which corresponds to neutron star models with the mass of $\lesssim 0.9M_\odot$), one could estimate the value of $η$ within $\sim 10\%$ accuracy, which makes a strong constraint on the EOS for neutron star matter. In addition, we find that the maximum $f$-mode frequency is strongly associated with the minimum radius of neutron star. That is, if one would observe a larger frequency of the $f$-mode, one might constrain the upper limit of the minimum neutron star radius.

description: We introduce several exact models for SU(3) spin chains: (1) a translationally invariant parent Hamiltonian involving four-site interactions for the trimer chain, with a three-fold degenerate ground state. We provide numerical evidence that the elementary excitations of this model transform under representation 3bar of SU(3) if the original spins of the model transform under rep. 3. (2) a family of parent Hamiltonians for valence bond solids of SU(3) chains with spin reps. 6, 10, and 8 on each lattice site. We argue that of these three models, only the latter two exhibit spinon confinement and a Haldane gap in the excitation spectrum.

description: The aim of this paper is to highlight an aspect of Mozart's production that has long been neglected by contemporary musicology: the strong influence of Orientalism in some of the composer's works. After a brief focus on musical antecedents related to Orientalism, mostly composed in France, Austria and Germany, we will then examine four of Mozart's most famous works in more detail: the Violin Concerto in A major K219, the Piano Sonata in A major K331 and the two renowned Singspiele: Die Entführung aus dem Serail K384 and Die Zauberflöte K620. For each of these works, all of them replete with Turqueries and exotic elements, different aspects will be examined with the aim of providing a multifaceted review of the main manifestations of Orientalism in European musical production of the 18th century. It is worth clarifying that what will be examined constitutes the original core of a series of elements that, in Art music production of the following centuries, will become a compositional norm with explicit reference to the Middle East, although derived from cultural and musical stereotypes. Furthermore, when discussing the East in a musical context, we do not refer to well-defined geographical and cultural boundaries. In this paper, we will also offer a brief analysis of this highly stereotyped and antithetical Eastern world, from a perspective strictly linked to the musical context, but one whose influences also partially extend to literature and visual arts.

Silicon uptake in rice and cucumbers

description: The study of silicon uptake in rice (Oryza sativa L. cv. Ml02) revealed an energy dependent, carrier-mediated system of silicon transport. This uptake system saturated at approximately 2 mM external Si and displayed a Vmax of 18.5 umol.g root-1.h"1 and a Km of 0.578 mM. Transport was found to not rely on transpiration rates. Studies of the effect of temperature, anoxia and KCN showed that the silicon uptake system was as strongly dependent on metabolic energy as potassium and several other major macronutrients, though it responded more slowly to such treatments than did potassium. The uptake system showed the characteristics of a derepressible system of uptake, in which plants deprived of silicon showed markedly enhanced rates of uptake as compared with plants grown in the presence of adequate silicon levels. The study of the kinetics of uptake in cucumbers (Cucumis sativus cv. Corona) revealed the possibility that, rather than passively absorbing silicon, the plants possess a low affinity saturable system responsible for the uptake of silicon, with a Km of 0.84 mM and a Vmax of 12.5 umol.g root-1.h-1. This system, however, did not appear to have a derepressible system of uptake such as was the case for rice. In the light of the growing body of information pointing to the importance of silicon as a plant nutrient, this study provides physiological evidence of silicon accumulation by two plant species and lays the foundation for fuller physiological and biochemical studies which may resolve the question of the essentiality of this element in plants.

description: Precision measurements of quantum systems often seek to probe or must account for the interaction with blackbody radiation. Over the past several decades, much attention has been given to AC Stark shifts and stimulated state transfer. For a blackbody in thermodynamic equilibrium, these two effects are determined by the expectation value of photon number in each mode of the Planck spectrum. Here, we explore how the photon number variance of an equilibrium blackbody generally leads to a parametric broadening of the energy levels of quantum systems that is inversely proportional to the square-root of the blackbody volume. We consider the the effect in two cases which are potentially highly sensitive to this broadening: Rydberg atoms and atomic clocks. We find that even in blackbody volumes as small as 1\,cm$^3$, this effect is unlikely to contribute meaningfully to transition linewidths.

description: The aim of this paper is to explore the presence of Cultural References in animated films and to investigate the approach adopted by Italian dubbing professionals to deal with such culture-specific elements. The analysis is based on a corpus of twelve American animated films released between 1955 and 2018 by companies such as Disney, Disney-Pixar, DreamWorks, 20th Century Fox, Illumination Entertainment, Universal Pictures. By analysing the transcriptions of the English and Italian dialogues and the films, the paper identifies food and drink Cultural References and examines the translation strategies used in Italian dubbing. A comparison of older and more recent films throws light on differences through time as well as on translation patterns. The linguistic analysis of the English and Italian dialogues is complemented with comments by two Italian dubbing professionals on dubbing practice in Italy.

Σκοπός της εργασίας είναι να απαντήσουμε στο πώς αντιλαμβάνονται οι εκπαιδευτικοί που διδάσκουν ΠΕ, ένα σχολείο «εναλλακτικό», όπως το Σχολείο Δεύτερης Ευκαιρίας, που απευθύνεται σε ενήλικους.
description: The teachers of Environmental Education in Second Chance Schools, mostly derived from secondary education, are teachers of a different perception, not conventional and traditional. They have experience the reality of school, they are sensitive to the problems of the teaching act and both are willing to experiment on new teaching methods. This study aims to answer how these teachers, who teach EE, perceive an “alternative” school, as the Second Chance School, which is aimed at adults.

description: We quantify the spatiotemporal evolution of the substorm ionospheric current system utilizing the SuperMAG 100+ magnetometers.We construct dynamical directed networks from this data for the first time. If the canonical cross-correlation between vector magnetic field perturbations observed at two magnetometer stations exceeds a threshold, they form a network connection. The time lag at which canonical cross-correlation is maximal determines the direction of propagation or expansion of the structure captured by the network connection. If spatial correlation reflects ionospheric current patterns, network properties can test different models for the evolving substorm current system.We select 86 isolated substorms based on nightside ground station coverage. We find, and obtain the timings for, a consistent picture in which the classic substorm current wedge forms. A current system is seen premidnight following the substorm current wedge westward expansion. Later, there is a weaker signal of eastward expansion. Finally, there is evidence of substorm-enhanced convection.

description: Η εργασία μας αυτή αποτελεί μια μικρή προσπάθεια γνωριμίας με τη διδασκαλία περί του Αγίου Πνεύματος του Αγίου Αμβροσίου Μεδιολάνων, όπως αυτή εκφράζεται μέσα από τα τρία βιβλία του έργου του De Spiritu Sancto, ενώ παράλληλα επιχειρεί να αναδείξει τον πρωτεύοντα ρόλο που διαδραμάτισε η θεολογική του σύλληψη και στάση στην καίρια αντιμετώπιση της πνευματολογικής αίρεσης τον 4ο αιώνα στη Δυτική χριστιανοσύνη. Ανιχνεύοντας μέσα στο κειμενό του τα δογματικά και θεολογικά στοιχεία που εκφράζουν την συνοδική διδασκαλία της Εκκλησίας σχετικά με το τρίτο πρόσωπο της Αγίας Τριάδος, οδηγούμαστε αβίαστα στο συμπέρασμα ότι ο Αμβρόσιος είναι ένας γνήσιος και συνεπής Νικαιικός θεολόγος μυστικά φλεγόμενος από την αγιαστική χάρη του Πνεύματος και ένας ποιμένας με ορθόδοξο φρόνημα που αφιέρωσε τη ζωή του ολάκερη στην υπεράσπιση της αλήθειας και την κατάρτιση του ποιμνίου του.
description: This essay represents a small effort to study the teaching on the Holy Spirit of the saint Ambrose of Milan, as it is expressed through the three books of his work De Spiritu Sancto and in parallel mode to emphasize the essential role of his theological conception and his position for fighting the pneumatological heresy during the 4th century in western Christendom. Tracing in his text the dogmatic and theological elements expressing the doctrine of the councils of the Church about the third person of the Holy Trinity, we come to acknowledge that Ambrose is an original and consistent Nicene theologian, secretly ablaze by the sanctifying grace of the Holy Spirit and an orthodox shepherd who dedicated his whole life to defend the truth and to instruct his flock.

description: Στην παρούσα εργασία μελετώνται οι ιστορικές και οι μυθικές μουσικές αγωνιστικές παραστάσεις κιθαριστικής και κιθαρωδίας της αρχαϊκής και της κλασικής εποχής, ενώ εξετάζεται και η μορφολογία της κιθάρας με βάση τα στοιχεία που προκύπτουν από τις μουσικές αυτές αγωνιστικές παραστάσεις. Για την προσέγγιση των προαναφερθέντων θεμάτων θεωρήθηκε σημαντικό να προσδιοριστεί η σημασία και ο ρόλος της μουσικής στην αρχαία Ελλάδα, να επιχειρηθεί η σημασιολογική ανάλυση του όρου «αγών» και να επιτευχθεί ο διαχωρισμός των μουσικών αγώνων σε ιστορικούς και μυθικούς. Μελετώνται οι μουσικοί αγώνες που διοργανώνονταν από τον 8ο αι. π.Χ. έως και τη ρωμαϊκή εποχή στα αρχαία ελληνικά ιερά, ενώ ταυτόχρονα διερευνάται η διεξαγωγή των μυθικών αγώνων κιθαριστικής και κιθαρωδίας. Μέσο προσέγγισης του θέματος αποτέλεσαν αφενός οι φιλολογικές πηγές και αφετέρου οι παραστάσεις σε αττικά, κατωιταλιωτικά και ετρουσκικά αγγεία των αρχαϊκών και των κλασικών χρόνων, καθώς και η παράσταση της «Βάσης της Μαντίνειας» του Πραξιτέλη.
description: In this paper the subject of research is the historical and mythical musical contest representations with guitar of archaic and classical period, while also under examination is the morphology of guitar according to the elements resulting from these representations. For the approach of the subjects mentioned it was considered important to show the importance and specific role of music in ancient Greece, to semantically analyse the term «ἀγών» (= contest) and to achieve the distinction between historical and mythical musical contests. We study the musical contests that took place in ancient greek temples from the 8th century B.C. until the roman period, while at the same time is examined the carrying out of mythical contests with guitar. The means of approach aroused to be on the one hand the literary sources and on the other hand the representations on attic, south italian and etruscan vases of archaic and classical period, as well as the representation of the «Base of Mantinea» of Praxiteles.
Exchange energy and generalized polarization in the presence of spin-orbit coupling in two dimensions

description: We discuss a general form of the exchange energy for a homogeneous system of interacting electrons in two spatial dimensions which is particularly suited in the presence of a generic spin-orbit interaction. The theory is best formulated in terms of a generalized fractional electronic polarization. Remarkably we find that a net generalized polarization does not necessarily translate into an increase in the magnitude of the exchange energy, a fact that in turn favors unpolarized states. Our results account qualitatively for the findings of recent experimental investigations.

description: The hyperfine structures of the $2\,^3\!S_1$ states of the $^6$Li$^+$ and $^7$Li$^+$ ions are investigated theoretically to extract the Zemach radii of the $^6$Li and $^7$Li nuclei by comparing with precision measurements. The obtained Zemach radii are larger than the previous values of Puchalski and Pachucki [\href{https://link.aps.org/doi/10.1103/PhysRevLett.111.243001}{Phys. Rev. Lett. {\bf 111}, 243001 (2013)}] and disagree with them by about 1.5 and 2.2 standard deviations for $^6$Li and $^7$Li, respectively. Furthermore, our Zemach radius of $^6$Li differs significantly from the nuclear physics value, derived from the nuclear charge and magnetic radii [\href{https://link.aps.org/doi/10.1103/PhysRevA.78.012513}{Phys. Rev. A {\bf 78}, 012513 (2008)}], by more than 6 sigma, indicating an anomalous nuclear structure for $^6$Li. The conclusion that the Zemach radius of $^7$Li is about 40\% larger than that of $^6$Li is confirmed. The obtained Zemach radii are used to calculate the hyperfine splittings of the $2\,^3\!P_J$ states of $^{6,7}$Li$^+$, where an order of magnitude improvement over the previous theory has been achieved for $^7$Li$^+$.
