Holidays on Ice: William Morris and Lavinia Greenlaw in Iceland
Creators: name: Cazalet-Boudigues, Alix
Publisher: name: Imaginaires
Year: 2023

description: Going away is an essential part of our conception of holidays, which is why Questions of Travel: William Morris in Iceland (2011) can help inform a definition of holiday poetics. The book combines large portions of William Morris’s Icelandic Journals, in particular from the first part which documents his 1871 journey to Iceland, with commentaries of Morris’s text by contemporary British poet Lavinia Greenlaw. The work as a whole draws attention to in-betweenness as a central characteristic of holiday writing. Both texts bring to the fore the unstable situation of the holidaymaker who has to find their place away from home while knowing this displacement to be only temporary. In-betweenness is also to be found in how Morris and Greenlaw recount the events of the journey. Calling it an adventure enables Morris to alternate between the sublime and the heroicomical, while Greenlaw oscillates between the universal and the particular in the psychological analysis of Morris’s experience. Genre is also considered: journal writing was not a common practice of Morris’s, and it is here presented as a freer form of expression than either letter or poetry writing. The generic affiliation of Greenlaw’s text is debated as well, given that it is published as non-fiction but is often more akin to free verse. Ultimately, a distinction between travel writing and holiday writing is attempted.

“Possibilities of a Pleasant Outing”: doing the don’ts in and about Florence in E. M. Forster’s "A Room with a View"
Creators: name: Coimbra, Cláudia
Publisher: name: Imaginaires
Year: 2022

description: On the threshold of adulthood young Lucy Honeychurch is a product of the upper-middle class Edwardian society, a puppet on a string of stifling conventions. Hers is an “undeveloped heart”, trapped by proprieties of the Victorian type that somewhat define her penchant for spontaneity as dangerous. Will a mini-Grand Tour to Italy, in the company of the typical morose and uptight chaperone, be just as uneventful as expected or will the Tuscan sun exert its summer magic? More than the portrait of a prospective lady, A Room with a View (1908) mirrors E. M. Forster’s take on a very particular topic, that of the English abroad. Both tourists and expatriates converge during the holiday season to test their moral stiffness while tempted by the appreciation of beauty, nature and passion. Disruptive characters, like the liberal Emersons, or turbulent events, like the furtive kiss on the hillside, thus become tools for an awakening of sorts on the part of the female self, as Lucy transposes and transcends a strict code of behaviour, and emancipates herself not only from the Baedeker (the famous portable travel guide) but also, and most importantly, from “the surface of things”. If one comes to Italy “for life” and not for anything else, if the room and the view are metaphors for contrasting worlds, what impact does the act of travelling produce in the traveller, and one inexperienced or ill prepared at that? And what are the domestic consequences of what one sees and feels in a country other than one’s own when a return is inevitable? The scope of this article is to assess not only the way(s) in which Forster privileges the search for individuality and feminine agency within the social-comedic plot of the novel, but also to confirm the sense of imbalance that holidays inevitably bring to the holiday-seeker, as hopes are dashed, expectations thwarted or new sensations embraced.

phenomenon of the Russian / Soviet dacha and the image of the izba in Andrei Tarkovsky’s movie "Mirror"
Creators: name: Pavlikova, Polina
Publisher: name: Imaginaires
Year: 2022

description: The meaning of dacha developed, and even radically changed over time, in the Russian Empire, then in the Soviet Union, and continues to evolve in contemporary Russia, as well as in the post-Soviet countries and other parts of Eastern Europe. The first dachas appeared at the time of Peter I, who presented lands to his nobles. In the Soviet Union, dachas were used mainly as vegetable gardens and became an essential resource for survival. During World War II, dachas, or country houses, were used for evacuations. In this article, the phenomenon of the Russian dacha with its recreational and salvatory functions is explored in the light of Michele Foucault’s heterotopia theory and Mikhail Bakhtin’s concept of chronotope. The analysis of the dacha space as an ambivalent site of leisure, and a necessity for survival is supported by the example of Andrei Tarkovsky’s film Mirror. In this autobiographical movie, the director shows how Alexei (his hero and alter-ego) and his family escaped to the countryside during the war and used the izba, a traditional Slavic house, as a shelter. However, physical salvation turns into spiritual trial. The powerful opposition between mind and body, emptiness (starvation) and fullness (wellbeing) is explicated in the poem “Eurydice” by Arseny Tarkovsky, which the director artistically appropriates in the movie to reinforce the semantic message of the visual text.

apparition du tourisme dans l’espace alpin helvétique
Creators: name: Mendes Baião, Hélder
Publisher: name: Imaginaires
Year: 2022

description: De la fin du XVIIIe siècle à la première moitié du XIXe siècle, l’aire helvétique est toujours plus visitée par les voyageurs européens. À l’époque des Lumières, on s’intéresse aux montagnes suisses, à leurs qualités géologiques, botaniques et aux particularités morales et politiques des Helvètes. À partir de ces observations se met en place une idée-image de la Suisse comme pays républicain aux mœurs austères. Dans la première moitié du XIXe siècle, cette représentation devenue mythique en Europe intrigue et attire les voyageurs toujours plus nombreux qui s’aventurent en Suisse. Alors que les voyages sont de plus en plus entrepris par la classe bourgeoise qui grossit et qui imite les coutumes de l’aristocratie, l’horizon politique de la Suisse ne s’efface pas des écrits. Au contraire, grâce au système politique des différents cantons la Suisse est parcourue comme une terre de liberté ouverte aux aventures. Nombreux sont les voyageurs à nous avoir laissé d’intrigants comptes rendus : Ramond de Carbonnières, William Coxe, Désiré Raoul-Rochette, Téobald Walsh, Victor Hugo, Stendhal, ne sont que quelques-uns parmi les plus célèbres à avoir été enthousiasmés par les paysages, mais aussi par les traditions républicaines et industrielles de la Suisse. Suivant les traces des travaux de Claude Reichler, François Rosset, Roland Ruffieux, etc., cet article analyse comment le tourisme a fait évoluer la Suisse et ses paysages, mais aussi comment le mythe d’une Suisse rurale et républicaine a profondément structuré les attentes des voyageurs, y compris lorsque ceux-ci allaient chercher en Helvétie un air pur et des bains pour revigorer leur santé.

The iconography of the summer vacation in Julie Delpy’s "Le Skylab" (2011)
Creators: name: Chaplin, Felicity
Publisher: name: Imaginaires
Year: 2022

description: Set over a weekend in the July summer holidays, Le Skylab (Julie Delpy 2011) depicts a typical family gathering in the late 1970s. On the occasion of her grandmother’s birthday, eleven-year-old Albertine and her parents travel by train from Paris to spend the weekend in Brittany with her extended family. The film is loosely autobiographical and is in part an evocation of Delpy’s own childhood; yet it nonetheless offers a universalised image of its milieu. Visually, Delpy’s film can best be described as an impression (in the sense given the term in relation to painting) of a summer weekend spent in Brittany in which Delpy draws on a cultural storehouse of images and tropes to construct a milieu at once particular and universally western, which captures a certain time and place and also offers a more generalised and relatable representation of the summer vacation through its recognisable images and themes. Taking an iconographical approach, this article is primarily a pictorial or compositional analysis of the representation of the summer vacation in Le Skylab. The focus is on two main motifs or tropes of the summer vacation: the summer place and the beach. It will also consider typical tropes and themes of the summer vacation narrative including arrival, summer romance, anticipation and departure.

description: We discuss a study to evaluate the extent to which free-response questions can be approximated by multiple-choice equivalents. Two carefully designed research-based multiple-choice questions were transformed into a free-response format and administered on the final exam in a calculus-based introductory physics course. The original multiple-choice questions were administered in another, similar introductory physics course on the final exam. Our findings suggest that carefully designed multiple-choice questions can reflect the relative performance on the free-response questions while maintaining the benefits of ease of grading and quantitative analysis, especially if the different choices in the multiple-choice questions are weighted to reflect the different levels of understanding that students display.

Summertime France as Ethno-Sociological Experiment
Creators: name: Frey, Hugo
Publisher: name: Imaginaires
Year: 2022

description: This article provides an original close reading of Nouvelle Vague filmmaker, Jacques Rozier’s major contribution to the representation of the summer holiday in post-war French cinema, Du côté d’Orouët (1969, released 1973). It analyses how Rozier’s comedy provides a unique sociology of changing gender and class structures, after the confrontations of May ’68. It suggests that the work is a forgotten masterpiece that has too often been overlooked in favour of Rozier’s own heritage as a figure from the Nouvelle Vague or in preference for work from more familiar contemporary directors who were working with the popular film stars of the period (a world that Rozier himself eschewed). Against that mainstream tradition of cinema, the deliberately minor, quasi ethnographic or sociological work of Rozier invented an original social-fiction which captured the trials and tribulations of the lower middle class youth who had gained some freedoms compared to in the 1950s, but who remained economically and culturally marginalized. Yet this group are not patronized by the filmmaker’s method which prefers empathy with its subjects, a position supported by Rozier’s powerful photography of the Atlantic ocean.

Ad Limine: Martin Parr’s Humans on the Beach. Re-empowering the English Seaside Resorts as Pop Culture
Creators: name: Pireddu, Silvia
Publisher: name: Imaginaires
Year: 2022

description: In the 1960s, the British working class gradually replaced the coastal landscape with the beaches of the Mediterranean. The coastal resorts of England experienced a decline and a transformation into “toxic” places, ad limine. The paper investigates British coastal culture as a source of hybrid narratives. Developing the work of Ingleby and Kerr (Coastal Cultures of the Long Nineteenth Century, Edinburgh UP, 2018), it discusses the visual coastal stories of Martin Parr to understand his view of Britishness. Parr’s photographs investigate places that witnessed the empowerment and profound transformation of the English working-class identity. He provides a non-judgmental analysis of humans performing universal and ritual actions in his coloured and saturated shots that evoke impressionist beach painting. The photographs represent the English northern beach as a bright and glossy place in contrast with the political and cultural issues faced by the British working class during the last decades of the past century.

description: We introduce diagrammatic technique for Hubbard nonequilibrium Green functions (NEGF). The formulation is an extension of equilibrium considerations for strongly correlated lattice models to description of current carrying molecular junctions. Within the technique intra-system interactions are taken into account exactly, while molecular coupling to contacts is used as a small parameter in perturbative expansion. We demonstrate the viability of the approach with numerical simulations for a generic junction model of quantum dot coupled to two electron reservoirs.

"Les Estivants", des gens de passage
Creators: name: Christofi, Christakis
Publisher: name: Imaginaires
Year: 2022

description: Les Estivants de M. Gorki s’inscrit dans le contexte historique et social qui précède de peu la révolution russe de 1905. L’auteur présente des personnages de la classe moyenne supérieure en villégiature d’été. Dans les datchas, maisons secondaires de campagne, le mode de vie de ces personnages rappelle la période prérévolutionnaire. Or, l’atmosphère estivale qui y règne est morne, imprégnée d’un message sociopolitique, et met en œuvre la nécessité d’un nouveau départ pour les estivants à la fin des vacances et, par extension, un changement général. Un lieu de vacances, les datchas, accueille un drame, à la fois individuel et collectif, qui s’attache à un moment transitoire confus. Les estivants incarnent cette confusion en ayant du mal à tracer une perspective pour l’avenir. Dès lors, la période estivale métaphorise une transition, la nécessité du passage à l’action qui implique une prise de conscience collective pour un nouveau départ dynamique.

Baryonic acoustic oscillations from 21cm intensity mapping: the Square Kilometre Array case

description: We quantitatively investigate the possibility of detecting baryonic acoustic oscillations (BAO) using single-dish 21cm intensity mapping observations in the post-reionization era. We show that the telescope beam smears out the isotropic BAO signature and, in the case of the Square Kilometer Array (SKA) instrument, makes it undetectable at redshifts $z\gtrsim1$. We however demonstrate that the BAO peak can still be detected in the radial 21cm power spectrum and describe a method to make this type of measurements. By means of numerical simulations, containing the 21cm cosmological signal as well as the most relevant Galactic and extra-Galactic foregrounds and basic instrumental effect, we quantify the precision with which the radial BAO scale can be measured in the 21cm power spectrum. We systematically investigate the signal-to-noise and the precision of the recovered BAO signal as a function of cosmic variance, instrumental noise, angular resolution and foreground contamination. We find that the expected noise levels of SKA would degrade the final BAO errors by $\sim5\%$ with respect to the cosmic-variance limited case at low redshifts, but that the effect grows up to $\sim65\%$ at $z\sim2-3$. Furthermore, we find that the radial BAO signature is robust against foreground systematics, and that the main effect is an increase of $\sim20\%$ in the final uncertainty on the standard ruler caused by the contribution of foreground residuals as well as the reduction in sky area needed to avoid high-foreground regions. We also find that it should be possible to detect the radial BAO signature with high significance in the full redshift range. We conclude that a 21cm experiment carried out by the SKA should be able to make direct measurements of the expansion rate $H(z)$ with competitive per-cent level precision on redshifts $z\lesssim2.5$.

Summertime: Time, Narrative and Queer Futures in Aciman’s "Call Me by Your Name"
Creators: name: Hoag, Ann Catherine
Publisher: name: Imaginaires
Year: 2022

description: André Aciman’s acclaimed first novel, Call Me by Your Name, retrospectively depicts the love affair between Elio and Oliver in an edenic Italian 1980s summer. Setting a story saturated with longing and nostalgia in the summertime seems to play with the chronotope of the summer as a period ripe for romantic experimentation. What sets Aciman’s text apart, though, is its deep concern with the phenomenology of time. Applying Paul Ricœur’s observations expounded in his Time and Narrative to the novel helps illuminate how Aciman employs emplotment, where the present is punctuated with references to the past and to the future, to destabilize the stubborn boundaries of time. The result is that Elio’s recounting of a distant past becomes a relevant present, never fully passed. The comingling of the past and present relates to Elizabeth Grosz’s explanations of Bergson’s reconsideration of chronology where the past and present ‘function in simultaneity.’ Grosz argues that Bergson’s sense of duration has consequences for the virtual possibilities not fully predicted by the past. As can be seen in Call Me by Your Name, the representation of time where the past is reworked in the present offers untimely ruptures of new potentials ‘later’ beyond the boundaries of the narrative. Thus, Aciman’s text is not simply a nostalgic work for a time of innocent yearning, but it is a reformulation of the past to create a virtual future where the queer pleasures of the summer are not limited by time.

description: We advocate the step change in properties of discrete $d$-level quantum systems, between $d=2$ and $d\geq 3$. Qubit systems, or multipartite systems containing qubit subsystem, are exceptional in their relative simplicity. One faces a step in complexity in valuating measures of quantum correlations for qutrits and then other higher dimensional qudits. There is a growing number of arguments leading to such conclusion: recently found no-go theorem for generalization of the Peres-Horodecki's PPT criterion \cite{sko}, change in geometry of state spaces of qubit and higher degree qudits (the so called 'generalized Bloch ball' is not a ball anymore), restricted possibilities for diagonalization of correlation matrices for bipartite systems, more difficult way for handling the set of relevant families of orthogonal projectors.

description: Postpartum care in cattle involves monitoring the health of the mother cow and her newborn calf immediately after calving. Key aspects include ensuring proper colostrum intake for the calf, maintaining a balanced diet for the dam, and conducting postpartum examinations to detect and address potential complications. Providing a clean and comfortable environment, along with timely reproductive management and vaccination programs, contributes to the overall well-being and productivity of the herd. Regular veterinary check-ups and strategic culling decisions further optimize postpartum care practices in cattle management.

description: We identify a pre-explosion counterpart to the nearby Type IIP supernova ASASSN-16fq (SN 2016cok) in archival Hubble Space Telescope (HST) data. The source appears to be a blend of several stars that prevents obtaining accurate photometry. However, with reasonable assumptions about the stellar temperature and extinction, the progenitor almost certainly had an initial mass M<17Msun, and was most likely in the mass range 8-12Msun. Observations once ASASSN-16fq has faded will have no difficulty accurately determining the properties of the progenitor. In 8 years of Large Binocular Telescope (LBT) data, no significant progenitor variability is detected to RMS limits of roughly 0.03 mag. Of the six nearby SN with constraints on low level variability, SN 1987A, SN 1993J, SN 2008cn, SN 2011dh, SN 2013ej and ASASSN-16fq, only the slowly fading progenitor of SN 2011dh showed clear evidence of variability.

description: Infrastructures are not inherently durable or fragile, yet all are fragile over the long term. Durability requires care and maintenance of individual components and the links between them. Astronomy is an ideal domain in which to study knowledge infrastructures, due to its long history, transparency, and accumulation of observational data over a period of centuries. Research reported here draws upon a long-term study of scientific data practices to ask questions about the durability and fragility of infrastructures for data in astronomy. Methods include interviews, ethnography, and document analysis. As astronomy has become a digital science, the community has invested in shared instruments, data standards, digital archives, metadata and discovery services, and other relatively durable infrastructure components. Several features of data practices in astronomy contribute to the fragility of that infrastructure. These include different archiving practices between ground- and space-based missions, between sky surveys and investigator-led projects, and between observational and simulated data. Infrastructure components are tightly coupled, based on international agreements. However, the durability of these infrastructures relies on much invisible work - cataloging, metadata, and other labor conducted by information professionals. Continual investments in care and maintenance of the human and technical components of these infrastructures are necessary for sustainability.

description: We present a population study of the star formation history of 1244 Type 2 AGN host galaxies, compared to 6107 inactive galaxies. A Bayesian method is used to determine individual galaxy star formation histories, which are then collated to visualise the distribution for quenching and quenched galaxies within each population. We find evidence for some of the Type 2 AGN host galaxies having undergone a rapid drop in their star formation rate within the last 2 Gyr. AGN feedback is therefore important at least for this population of galaxies. This result is not seen for the quenching and quenched inactive galaxies whose star formation histories are dominated by the effects of downsizing at earlier epochs, a secondary effect for the AGN host galaxies. We show that histories of rapid quenching cannot account fully for the quenching of all the star formation in a galaxy's lifetime across the population of quenched AGN host galaxies, and that histories of slower quenching, attributed to secular (non-violent) evolution, are also key in their evolution. This is in agreement with recent results showing both merger-driven and non-merger processes are contributing to the co-evolution of galaxies and supermassive black holes. The availability of gas in the reservoirs of a galaxy, and its ability to be replenished, appear to be the key drivers behind this co-evolution.

description: The AdS/CFT correspondence provides quantum theories of gravity in which spacetime and gravitational physics emerge from ordinary non-gravitational quantum systems with many degrees of freedom. Recent work in this context has uncovered fascinating connections between quantum information theory and quantum gravity, suggesting that spacetime geometry is directly related to the entanglement structure of the underlying quantum mechanical degrees of freedom and that aspects of spacetime dynamics (gravitation) can be understood from basic quantum information theoretic constraints. In these notes, we provide an elementary introduction to these developments, suitable for readers with some background in general relativity and quantum field theory. The notes are based on lectures given at the CERN Spring School 2014, the Jerusalem Winter School 2014, the TASI Summer School 2015, and the Trieste Spring School 2015.

description: Valley-spin coupling in transition-metal dichalcogenides (TMDs) can result in unusual spin transport behaviors under an external magnetic field. Nonlocal resistance measured from 2D materials such as TMDs via electrical Hanle experiments are predicted to exhibit nontrivial features, compared with results from conventional materials due to the presence of intervalley scattering as well as a strong internal spin-orbit field. Here, for the first time, we report the all-electrical injection and non-local detection of spin polarized carriers in trilayer MoS_2 films. We calculate the Hanle curves theoretically when the separation between spin injector and detector is much larger than spin diffusion length, \lamda_s. The experimentally observed curve matches the theoretically-predicted Hanle shape under the regime of slow intervalley scattering. The estimated spin life-time was found to be around 110 ps at 30 K.

description: In the absence of external excitation, light trapped within a dielectric medium generally decays by leaking out (and also by getting absorbed within the medium). We analyze the leaky modes of a parallel-plate slab, a solid glass sphere, and a solid glass cylinder, by examining those solutions of Maxwell's equations (for dispersive as well as non-dispersive media) which admit of a complex-valued oscillation frequency. Under certain circumstances, these leaky modes constitute a complete set into which an arbitrary distribution of the electromagnetic field residing inside a dielectric body can be expanded. We provide completeness proofs, and also present results of numerical calculations that illustrate the relationship between the leaky modes and the resonances of dielectric cavities formed by a simple parallel-plate slab, a glass sphere, and a glass cylinder.

From the infrared part of the optical conductivity, we discover that the scattering rate of mobile carriers above 200 K exhibits saturation at the Mott-Ioffe-Regel limit of metallic transport. However, the dc resistivity continues to increase with temperature above 200 K due to the loss of Drude spectral weight. The loss of Drude spectral weight with increasing temperature is seen in a wide temperature range in the uncollapsed tetragonal phase, and this spectral weight is recovered at energy scales about one order of magnitude larger than the Fermi energy scale in these semimetals. The phenomena noted above have been observed previously in other correlated metals in which the dominant interactions are electronic in origin. Further evidence of significant electron-electron interactions is obtained from the presence of quadratic temperature and frequency-dependent terms in the scattering rate at low temperatures and frequencies in the uncollapsed tetragonal structures of La-doped and Pr-doped CaFe2As2. For temperatures below the structure collapse transition in Pr-doped CaFe2As2 at 70 K, the scattering rate decreases due to weakening of electronic correlations, and the Drude spectral weight decreases due to modification of the low-energy electronic structure.

description: We present a detailed discussion of the structure of the low-lying positive-parity energy spectrum of $^{12}$C from a no-core shell-model perspective. The approach utilizes a fraction of the usual shell-model space and extends its multi-shell reach via the symmetry-based no-core symplectic shell model (NCSpM) with a simple, physically-informed effective interaction. We focus on the ground-state rotational band, the Hoyle state and its $2^+$ and $4^+$ excitations, as well as the giant monopole $0^+$ resonance, which is a vibrational breathing mode of the ground state. This, in turn, allows us to address the open question about the structure of the Hoyle state and its rotational band. In particular, we find that the Hoyle state is best described through deformed prolate collective modes rather than vibrational modes, while we show that the higher-lying giant monopole $0^+$ resonance resembles the oblate deformation of the $^{12}$C ground state. In addition, we identify the giant monopole $0^+$ and quadrupole $2^+$ resonances of selected light and intermediate-mass nuclei, along with other observables of $^{12}$C, including matter rms radii, electric quadrupole moments, as well as $E2$ and $E0$ transition rates.

description: We present synthetic far- and near-ultraviolet (FUV and NUV) maps of M31, both with and without dust reddening. These maps were constructed from spatially-resolved star formation histories (SFHs) derived from optical Hubble Space Telescope imaging of resolved stars, taken as part of the Panchromatic Hubble Andromeda Treasury program. We use stellar population synthesis modeling to generate synthetic UV maps with projected spatial resolution of $\sim$100 pc ($\sim$24 arcseconds) The predicted UV flux agrees well with the observed flux, with median ratios between the modeled and observed flux of $\log_{10}(f^{syn}/f^{obs}) = 0.03\pm0.24$ and $-0.03\pm0.16$ in the FUV and NUV, respectively. This agreement is particularly impressive given that we used only optical photometry to construct these UV maps. We use the dust-free maps to examine properties of obscured flux and star formation by comparing our reddened and dust-free FUV flux maps with the observed FUV and FUV+24μm flux to examine the fraction of obscured flux. The synthetic flux maps require that $\sim$90% of the FUV flux in M31 is obscured by dust, while the GALEX-based methods suggest that $\sim$70% of the flux is obscured. This increase in the obscured flux estimate is driven by significant differences between the dust-free synthetic FUV flux and that derived when correcting the observed FUV for dust with 24μm observations. The difference is further illustrated when we compare the SFRs derived from the FUV+24μm flux with the 100 Myr average SFR from the SFHs. The 24μm-corrected FUV flux underestimates the SFR by a factor of $\sim$2.3 - 2.5. [abridged]

“Lavorare è vestire la terra”. Summer memories in Cesare Pavese’s "Feria d’agosto"
Creators: name: Monateri, Valentina
Publisher: name: Imaginaires
Year: 2022

description: Feria d’agosto is a collection of short stories from 1946 by Italian author Cesare Pavese. This can be defined as a key publication in Pavese’s work: not only since it contains an inventory of strongly evocative pavesean themes, but also for the great relevance the author gives to the summertime and the idea of feria, which he will re-call again in the more mature triptych of short novels enclosed under the title La bella estate (1949). Indeed, the August ferie symbolize an important topic in the post-war Italian narrative and, especially, in Pavese’s portrayal of the Italian culture of the mid-40s (Alfano, De Medici, Tortora, 2020). The book is divided into three sections, whose titles are significant: “il mare”, “la città”, “la vigna”. The sea, the city and the vineyard are all central loci in Pavese’s writing, where narrative and mythical telling meet. In the first section, all the main characters are boys on the threshold of adolescence, which come from their status of innocence to the one of conscience. In the second section, the city is the place of the working days portrayed as the locus of cognitive experiences, where we can find recurring Pavese’s elements, from the summer deserted streets to the solitary men. While, in the third section, the vineyard represents a religious, mythical element in Pavese’s writings whose interpretation throughout his work is polysemic (Procaccini, 1985). The summertime, then, has a multifarious meaning in Pavese’s work and especially in Feria d’agosto, where the author tends to associate it with childhood, with a ritual passage from ignorance to wisdom, and ultimately, with the relationship modernity maintains with classical myths, thus working on a all-personal mythical method which the Italian literature, in the 40s, was inheriting from the English, French and American literatures (Fielder, 1954).

description: When considering modern and contemporary summer holidays as a social phenomenon, there might be a temptation to read them solely as a buoyant ramification of late capitalist habits, a garish bourgeois mass entertainment institution as futile and platitudinous as can be, leading to acritical tourism, hypertrophied infrastructural developments, dishonestly overpriced meals, and cheesy events aiming at a shallow carefree amusement. The history and cultural role of this fundamental recurring experience is, however, much more complex and significative than this clichéd portrait might reveal, and its legal birth in the modern age is the result of paramount rights arduously claimed by the European working classes in the interwar period.

Alternative Self-dual Gravity in Eight Dimensions

description: We develop an alternative Ashtekar formalism in eight dimensions. In fact, using a MacDowell-Mansouri physical framework and a self-dual curvature symmetry we propose an action in eight dimensions in which the Levi-Civita tenor with eight indices plays a key role. We explicitly show that such an action contains number of linear, quadratic and cubic terms in the Riemann tensor, Ricci tensor and scalar curvature. In particular, the linear term is reduced to the Einstein-Hilbert action with cosmological constant in eight dimensions. We prove that such a reduced action is equivalent to the Lovelock action in eight dimensions.

description: The formation of ice affects many aspects of our everyday life as well as technologies such as cryotherapy and cryopreservation. Foreign substances almost always aid water freezing through heterogeneous ice nucleation, but the molecular details of this process remain largely unknown. In fact, insight into the microscopic mechanism of ice formation on different substrates is difficult to obtain even via state-of-the-art experimental techniques. At the same time, atomistic simulations of heterogeneous ice nucleation frequently face extraordinary challenges due to the complexity of the water-substrate interaction and the long timescales that characterize nucleation events. Here, we have investigated several aspects of molecular dynamics simulations of heterogeneous ice nucleation considering as a prototypical ice nucleating material the clay mineral kaolinite, which is of relevance in atmospheric science. We show via seeded molecular dynamics simulations that ice nucleation on the hydroxylated (001) face of kaolinite proceeds exclusively via the formation of the hexagonal ice polytype. The critical nucleus size is two times smaller than that obtained for homogeneous nucleation at the same supercooling. Previous findings suggested that the flexibility of the kaolinite surface can alter the time scale for ice nucleation within molecular dynamics simulations. However, we here demonstrate that equally flexible (or non flexible) kaolinite surfaces can lead to very different outcomes in terms of ice formation, according to whether or not the surface relaxation of the clay is taken into account. We show that very small structural changes upon relaxation dramatically alter the ability of kaolinite to provide a template for the formation of a hexagonal overlayer of water molecules at the water-kaolinite interface, and that this relaxation therefore determines the nucleation ability of this mineral.

description: The inner regions of the solar corona from 1-2.5 Rsun are poorly sampled both from the ground and space telescopes. A solar eclipse reduces the sky scattered background intensity by a factor of about 10,000 and opens a window to view this region directly. The goal of the Citizen {\it Continental-America Telescopic Eclipse} (CATE) Experiment is to take a 90-minute time sequence of calibrated white light images of this coronal region using 60 identical telescopes spread from Oregon to South Carolina during the 21 August 2017 total solar eclipse. Observations that can address questions of coronal dynamics in this region can be collected with rather modest telescope equipment, but the large dynamic range of the coronal brightness requires careful camera control. The instruments used for test runs on the Faroe Islands in 2015 and at five sites in Indonesia in 2016 are described. Intensity calibration of the coronal images is done and compared with previous eclipse measurements from November \& Koutchmy (1996) and Bazin et al. (2015). The change of coronal brightness with distance from the Sun seen in the 2016 eclipse agrees with observations from the 1991 eclipse but differ substantially from the 2010 eclipse. The 2015 observations agree with 2016 and 1991 solar radii near the Sun, but are fainter at larger distances. Problems encountered during these test runs are discussed as well the solutions which will be implemented for the 2017 eclipse experiment.
