description: Altmetrics are tools for measuring the impact of research beyond scientific communities. In general, they measure online mentions of scholarly outputs, such as on online social networks, blogs, and news sites. Some stakeholders in higher education have championed altmetrics as a new way to understand research impact and as an alternative or supplement to bibliometrics. Contrastingly, others have criticized altmetrics for being ill conceived and limited in their use. This chapter explores the values and limits of altmetrics, including their role in evaluating, promoting, and disseminating research.

description: Micro aerial vehicles (MAVs) encounter aerodynamic challenges due to their small size and low flying speed, often experiencing stall at low angles of attack. This study aims to investigate the effects of sectional airfoil geometries, including thickness, maximum thickness location, and camber, on the aerodynamic performance of fixed-wing MAVs inspired by the passive control method observed in Humpback whales. The investigation employs 3D, unsteady, viscous, and turbulent simulations using the detached eddy simulation turbulence model to understand the physical phenomena. Results reveal that increasing the thickness of the infinite wing by approximately 9.5% results in a decrease of lift and drag coefficients by 19.8% and 12%, respectively. Furthermore, shifting the maximum thickness location from 18%c to 36%c enhances the lift-to-drag ratio (L/D) by nearly 16%. However, an increase in camber leads to a rise in drag coefficient. In conclusion, this research sheds light on the aerodynamic effects of sectional airfoil geometries on fixed-wing MAVs, particularly in pre-stall conditions. Understanding these effects contributes to the development of strategies for improving MAV maneuverability and aerodynamic performance.

description: ElectrodeNet, a deep learning based sound coding strategy for the cochlear implant (CI), is proposed to emulate the advanced combination encoder (ACE) strategy by replacing the conventional envelope detection using various artificial neural networks. The extended ElectrodeNet-CS strategy further incorporates the channel selection (CS). Network models of deep neural network (DNN), convolutional neural network (CNN), and long short-term memory (LSTM) were trained using the Fast Fourier Transformed bins and channel envelopes obtained from the processing of clean speech by the ACE strategy. Objective speech understanding using short-time objective intelligibility (STOI) and normalized covariance metric (NCM) was estimated for ElectrodeNet using CI simulations. Sentence recognition tests for vocoded Mandarin speech were conducted with normal-hearing listeners. DNN, CNN, and LSTM based ElectrodeNets exhibited strong correlations to ACE in objective and subjective scores using mean squared error (MSE), linear correlation coefficient (LCC) and Spearman's rank correlation coefficient (SRCC). The ElectrodeNet-CS strategy was capable of producing N-of-M compatible electrode patterns using a modified DNN network to embed maxima selection, and to perform in similar or even slightly higher average in STOI and sentence recognition compared to ACE. The methods and findings demonstrated the feasibility and potential of using deep learning in CI coding strategy.

description: Semi-coke is a problematic material to burn, and how to use it is a typical problem enterprises face. This paper proposes a method to improve the performance of blended Semi-coke coal water slurry based on multi-peak distribution technology. By blending Semi-coke, the coal water slurry concentration can be increased by a maximum of 3.83%. In addition, the blending of Semi-coke reduced the flow property index (n) of coal water slurry from 0.66 to 0.51, the yield stress from 29.25 Pa to 12.45 Pa, and enhanced the pseudoplasticity of coal water slurry. Meanwhile, this paper establishes the relationship between the bimodal parameters and coal water slurry concentration and finds that the peak 2 positions, peak 2 height, peak 2 areas, and peak spacing negatively correlate with the slurry formation concentration. Finally, this paper found that the doping of Semi-coke can improve the gasification performance of coal water slurry. The ignition temperature was reduced from 884.9°C to 854.3°C and the burnout temperature from 1067.4°C to 1026.6°C after Semi-coke blending.

description: The spatially nonlocal response functions of graphene obtained on the basis of first principles of quantum field theory using the polarization tensor are considered in the areas of both the on-the-mass-shell and off-the-mass-shell waves. It s shown that at zero frequency the longitudinal permittivity of graphene is the regular function, whereas the transverse one possesses a double pole for any nonzero wave vector. According to our results, both the longitudinal and transverse permittivities satisfy the dispersion (Kramers-Kronig) relations connecting their real and imaginary parts, as well as expressing each of these permittivities along the imaginary frequency axis via its imaginary part. For the transverse permittivity, the form of an additional term arising in the dispersion relations due to the presence of a double pole is found. The form of dispersion relations is unaffected by the branch points which arise on the real frequency axis in the presence of spatial nonlocality. The obtained results are discussed in connection with the well known problem of the Lifshitz theory which was found to be in conflict with the measurement data when using the much studied response function of metals. A possible way of attack on this problem based on the case of graphene is suggested.

Subjects: spoken language; preverbal position; L2 teaching; language awareness; language competence

description: This paper describes the outcome of a pilot analysis conducted on a corpus containing two dialogues in contemporary spontaneous spoken German. The analysis aims to check the syntactic structures occurring in the preverbal position (front field and pre-front field) of declarative clauses and compare them with the grammatical rules of written German taught in German L2 classes. The author addresses the issue both from a grammatical and didactic analytical perspective and comes to the conclusion that the teaching of German L2 should take into account not only the grammatical structures of written language, but also those of spoken language in order to stimulate learner awareness of language complexity and improve linguistic competence in spoken German. Based upon the results, useful advice for the teaching of grammar in German L2 is given.

description: The ability to control Poisson's ratio of functional materials has been one of the main objectives of researchers attempting to develop structures efficient from the perspective of protective, biomedical and soundproofing devices. This task becomes even more challenging at small scales, such as the microscale, where the possibility to control mechanical properties of functional materials is very significant, like in the case of flexible electronics. In this work, we propose novel microscopic 2D and 3D functionally-graded mechanical metamaterials capable of exhibiting a broad range of Poisson's ratio depending on their composition. More specifically, we show that upon adjusting the number of structural elements corresponding to one type of the substructure at the expense of another, it is possible to change the resultant Poisson's ratio of the entire system from highly positive to highly negative values as well as to achieve arbitrary intermediate values. Finally, in addition to static properties, we also analyze the dynamic properties of these structures. Namely, we show how the variation in the composition of the considered mechanical metamaterials affects the velocity of a wave propagating through the system. This, in turn, could be essential in the case of applications utilizing localized wave attenuation or sensors.

description: In this review we address the progress that has been made toward the understanding the population of Magellanic Cloud planetary nebulae since the last Magellanic Cloud Symposium. Planetary nebulae in the Clouds are not only important as key probes of stellar and ISM evolution in these galaxies, but also reflect the evolution of AGB stars and beyond in low-metallicity environments. We present the recent surveys results, including the wide fields ground-based search for PNe, the {\it HST} study of the resolves ejecta and their central stars, and the {\it Spitzer} analysis of the gas contents of these ejecta. Finally, we show how Magellanic Cloud PNe can be used to constraint the distance scale of galactic PNe.

description: We demonstrate how to directly study non-Abelian statistics for a wide class of exactly solvable many-body quantum systems. By employing exact eigenstates to simulate the adiabatic transport of a model's quasiparticles, the resulting Berry phase provides a direct demonstration of their non-Abelian statistics. We apply this technique to Kitaev's honeycomb lattice model and explicitly demonstrate the existence of non-Abelian Ising anyons confirming the previous conjectures. Finally, we present the manipulations needed to transport and detect the statistics of these quasiparticles in the laboratory. Various physically realistic system sizes are considered and exact predictions for such experiments are provided.

Knowledge, Cosmic Generation and the World in Madhva’s Interpretation of Chāndogyopaniṣad 6
Creators: name: Williams, Michael
Publisher: name: Rivista di Studi Sudasiatici
Year: 2010

description: The subject of this article is the hermeneutical theology of the 13th century Vaiṣṇava Vedānta theologian, Madhvācārya. My focus is his interpretation of a single Upaniṣadic text, namely the sixth adhyāya of the Chāndogyopaniṣad which culminates in the celebrated mahāvākya tattvam asi, or atattvam asi, according to the Mādhva tradition’s controversial reading. This celebrated episode which takes the form of a dialogue between the haughty Śvetaketu and his father became central to the exegetical activities of medieval Vedānta traditions, particularly in debates concerning the nature of cosmogony and the individual’s relationship to the reality that cosmic generation produces. Here, I will attempt to show how a close, systematic reading and comparison of the diverse texts in which Madhva discusses this, certain aspects of this passage clarify his understanding of important components of it and all point to a single unity of meaning and purpose, in other words the ekavākyatā of the text.

The stochastic component of the input signal results in the infrared cutoff of Kondo transmission. The stochastization of the orbital component of the Kondo effect in triple quantum dots results in a noise-induced SU(4) - SU(2) quantum transition.

description: We study early universe with a particular form of F(T) Telleparallel gravity theory, in which inflation is driven by a scalar field. To ensure slow rollover, two different potentials are chosen in a manner, such that they remain almost flat for large initial value of the scalar field. Inflationary parameters show wonderful fit with the presently available Planck's data set. The energy scale of inflation is sub-Planckian and graceful exit from inflation is also administered. The chosen form of F(T) administers late-time cosmic acceleration too. In the process, unification of the early inflation with late-time acceleration is ensured. Unfortunately, a decelerated radiation dominated era is only possible with a different form of (quartic) potential, which being devoid of a flat section does not admit slow rollover.

description: Sorkin has introduced a new, observer independent, interpretation of quantum mechanics that can give a successful realist account of the 'quantum microworld' as well as explaining how classicality emerges at the level of observable events for a range of systems including single time 'Copenhagen measurements'. This 'co-event interpretation' presents us with a new ontology, in which a single 'co-event' is real. A new ontology necessitates a review of the dynamical & predictive mechanism of a theory, and in this paper we begin the process by exploring means of expressing the dynamical and predictive content of histories theories in terms of co-events.

Constraints on the models of the origin of high-energy astrophysical neutrinos

description: The existence of astrophysical neutrinos with energies of tens of TeV and higher has been reliably established by the IceCube experiment; the first confirmations of this discovery are being obtained with the ANTARES and Baikal-GVD facilities. The observational results do not fully agree with what was expected before the start of these experiments. The origin of these neutrinos has not been conclusively established, and simple theoretical models, popular for decades, cannot explain all observational data. This review summarizes the experimental results with emphasis on those important for constraining theoretical models, discusses various scenarios for the origin of high-energy neutrinos and briefly lists particualr classes of their potential astrophysical sources. It is demonstrated that the observational data may be explained if the flux of astrophysical neutrinos includes the contribution of extragalactic sources, dominating at the highest energies, and the Galactic component, significant only at neutrino energies

description: We report time-series photometry for 16 variable stars located in the central part of the globular cluster NGC 6752. The sample includes 13 newly identified objects. The precision of our differential photometry ranges from 1 mmag at V=14.0 to 10 mmag at V=18.0. We detected 4 low amplitude variables located on the extended horizontal branch (EHB) of the cluster. They are candidate binary stars harboring sdB subdwarfs. A candidate degenerate binary was detected about 2 mag below the faint end of the EHB. The star is blue and its light curve is modulated with a period of 0.47 d. We argue that some of the identified variable red/blue stragglers are ellipsoidal binaries harboring degenerate stars. They have low amplitude sine-like light curves and periods from a few hours to a few days. Spectroscopic observations of such objects may lead to the detection of detached inactive binaries harboring stellar mass black holes or neutron stars. No binaries of this kind are known so far in globular clusters although their existence is expected based on the common occurrence of accreting LMXBs and millisecond pulsars. An eclipsing SB1 type binary was identified on the upper main sequence of the cluster. We detected variability of optical counterparts to two X-ray sources located in the core region of NGC 6752. The already known cataclysmic variable B1=CX4 experienced a dwarf nova type outburst. The light curve of an optical counterpart to the X-ray source CX19 exhibited modulation with a period 0.113 d. The same periodicy was detected in the HST-ACS data. The variable is located on the upper main sequence of the cluster. It is an excellent candidate for a close degenerate binary observed in quiescence.

description: The software industry is successful, if it can draw the complete attention of the customers towards it. This is achievable if the organization can produce a high quality product. To identify a product to be of high quality, it should be free of defects, should be capable of producing expected results. It should be delivered in an estimated cost, time and be maintainable with minimum effort. Defect Prevention is the most critical but often neglected component of the software quality assurance in any project. If applied at all stages of software development, it can reduce the time, cost and resources required to engineer a high quality product.

description: This paper aims to study the configuration of two components caused by rotational and tidal distortions in the model of a binary system. The potentials of the two distorted components can be approximated to 2nd-degree harmonics. Furthermore, both the accretion luminosity ($σ_{i}$) and the irradiative luminosity are included in stellar structure equations. The equilibrium structure of rotationally and tidally distorted star is exactly a triaxial ellipsoids. A formula describing the isobars is presented, and the rotational velocity and the gravitational acceleration at the primary surface simulated. The results show the distortion at the outer layers of the primary increases with temporal variation and system evolution. Besides, it was observed that the luminosity accretion is unstable, and the curve of the energy-generation rate fluctuates after the main sequence in rotation sequences. The luminosity in rotation sequences is slightly weaker than that in non-rotation sequences. As a result, the volume expands slowly. Polar ejection is intensified by the tidal effect. The ejection of an equatorial ring may be favoured by both the opacity effect and the $g_{e}(θ,φ)$-effect in the binary system.

description: The study of the evolution of the Tully-Fisher relation has been controversial in the past years. The main difficulty is in determining the required parameters for intermediate and high redshift galaxies. This work aims to identify the main problems of the study of the Tully-Fisher relation at high redshift using optical emission lines, in order to draw conclusions about the possible evolution of this relation in the B, R, and I-bands. With this aim, the rotational velocities obtained from the widths of different optical lines using DEEP2 spectra are compared. Morphology has been determined via HST images, using and comparing different methodologies. Instrumental magnitudes are then corrected for K and extinction and the absolute magnitudes derived for the concordance cosmological model. Finally, the optical Tully-Fisher relations in B, R, and I-bands at different redshifts up to z = 1.3 are derived. Although most studies (this one included) find evidence of evolution, the results are not conclusive enough, since the possible luminosity evolution is within the scattering of the relation, and the evolution in slope is difficult to determine because at high redshift only the brightest galaxies can be measured. Nevertheless, our study shows a clear tendency, which is the same for all bands studied, that favours a luminosity evolution where galaxies were brighter in the past for the same rotation velocity. This result also implies that the colour of the Tully-Fisher relation does not change with redshift, supporting the collapse model versus the accretion model of disc galaxy formation.

description: The interference of polariton guiding modes propagating through "traffic circle" waveguides composed of dielectric spherical particles is investigated. The dependence of intensity of the wave on the position of the particle was studied using the multisphere the Mie scattering formalism. We show that if the frequency of light belongs to the passband of the waveguide, electromagnetic waves may be considered as two optical beams running along a circle in opposite directions and interfering with each other. Indeed, the obtained intensity behavior can be represented as a simple superposition of two waves propagating around a circle in opposite directions. The applications of this interference are discussed.

Subjects: hegemony; pluricentrism; linguistic teaching

description: The syncretic cultural identity, in which the Spanish language and its linguistic hegemony are grounded and have reflected its political hegemony, led Spain to take on a predominant role in standardization over the centuries. However, the present situation of the Spanish language is characterized by pluricentrism covering the vast territory in which the language is spoken. This means that a number of cen- ters have set up prestigious standard models providing norms for a country or region. Therefore, a fair enactment of this polycentrism requires national norms, different ways of codification of the Spanish language, answers to geographical and social forms which have split after a common departure and the idea that the varieties of the Spanish language fulfill speakers’ different expressive requirements and help to enhance national identities, in the face of the domination of the peninsular model. This point of view must guide linguistic research, methodology in lexicography, school grammar, translation of foreign languages and especially the teaching of Spanish as L2.

description: The Thermofield Dynamics (TFD) formalism is considered. In this context, a Lorentz-breaking scalar field theory is introduced. In contrast to the Matsubara formalism, the best-known approach to introducing the temperature effect, TFD is a real-time formalism and is a topological field theory. While in Matsubara the temperature effects are introduced as a consequence of a compactification of the field in a finite interval on the time axis, in the TFD this effect emerges through a condensed state related to the Bogoliubov transformation. An advantage of the TFD formalism is that different topologies, which lead to different effects, can be chosen. Here, three different topologies are considered. Then the Stefan-Boltzmann law and Casimir effect at zero and non-zero temperature are calculated. This is a unique feature of TFD, which allows us to treat different phenomena in the same way.

description: The Function point analysis (FPA) method is the preferred scheme of estimation for project managers to determine the size, effort, schedule, resource loading and other such parameters. The FPA method by International Function Point Users Group (IFPUG) has captured the critical implementation features of an application through fourteen general system characteristics. However, Non- functional requirements (NFRs) such as functionality, reliability, efficiency, usability, maintainability, portability, etc. have not been included in the FPA estimation method. This paper discusses some of the NFRs and tries to determine a degree of influence for each of them. An attempt to factor the NFRs into estimation has been made. This approach needs to be validated with data collection and analysis.

description: The weak lensing power spectrum carries cosmological information via its dependence on the growth of structure and on geometric factors. Since much of the cosmological information comes from scales affected by nonlinear clustering, measurements of the lensing power spectrum can be degraded by non-Gaussian covariances. Recently there have been conflicting studies about the level of this degradation. We use the halo model to estimate it and include new contributions related to the finite size of lensing surveys, following Rimes and Hamilton's study of 3D simulations. We find that non-Gaussian correlations between different multipoles can degrade the cumulative signal-to-noise for the power spectrum amplitude by up to a factor of 2 (or 5 for a worst-case model that exceeds current N-body simulation predictions). However, using an eight-parameter Fisher analysis we find that the marginalized errors on individual parameters are degraded by less than 10% (or 20% for the worst-case model). The smaller degradation in parameter accuracy is primarily because: individual parameters in a high-dimensional parameter space are degraded much less than the volume of the full Fisher ellipsoid; lensing involves projections along the line of sight, which reduce the non-Gaussian effect; some of the cosmological information comes from geometric factors which are not degraded at all. We contrast our findings with those of Lee & Pen (2008) who suggested a much larger degradation in information content. Finally, our results give a useful guide for exploring survey design by giving the cosmological information returns for varying survey area, depth and the level of some systematic errors.

description: Some explosion models for Type Ia supernovae (SN Ia), such as the gravitationally confined detonation (GCD) or the double detonation sub-Chandrasekhar (DDSC) models, rely on the spontaneous initiation of a detonation in the degenerate C/O material of a white dwarf. The length scales pertinent to the initiation of the detonation are notoriously unresolved in multi-dimensional stellar simulations, prompting the use of results of 1D simulations at higher resolution, such as the ones performed for this work, as guidelines for deciding whether or not conditions reached in the higher dimensional full star simulations successfully would lead to the onset of a detonation. Spontaneous initiation relies on the existence of a suitable gradient in self-ignition (induction) times of the fuel, which we set up with a spatially localized non-uniformity of temperature -- a hot spot. We determine the critical (smallest) sizes of such hot spots that still marginally result in a detonation in white dwarf matter by integrating the reactive Euler equations with the hydrodynamics code FLASH. We quantify the dependences of the critical sizes of such hot spots on composition, background temperature, peak temperature, geometry, and functional form of the temperature disturbance, many of which were hitherto largely unexplored in the literature. We discuss the implications of our results in the context of modeling of SNe Ia.

Positivity issues for the pinch-technique gluon propagator and their resolution

description: Although gauge-boson propagators in asymptotically-free gauge theories satisfy a dispersion relation, they do not satisfy the Källen-Lehmann (KL) representation because the spectral function changes sign. We argue that this is a simple consequence of asymptotic freedom. On the basis of the QED-like Ward identities of the pinch technique (PT) we claim that the product of the coupling $g^2$ and the scalar part $\hat{d}(q^2)$ of the PT propagator, which is both gauge invariant and renormalization-group invariant, can be factored into the product of the running charge $\bar{g}^2(q^2)$ and a term $\hat{H}(q^2)$ both of which satisfy the KL representation although their product does not. We show that this behavior is consistent with some simple analytic models that mimic the gauge-invariant PT Schwinger-Dyson equations (SDE) provided that the dynamic gauge boson mass is sufficiently large. The PT SDEs do not depend directly on the PT propagator through $\hat{D}$ but only through $\hat{H}$.

Yeats’s Autobiographies and the Making of the Self
Creators: name: Cotta Ramusino, Elena
Publisher: name: Biblioteca di Studi di Filologia Moderna: Series, Journals and Workshop
Year: 2013

description: Both in his prose and poetry William Butler Yeats showed a life- long interest in the shaping of the self, achieved through a careful rearrangement of experience. Autobiographies is a collection of texts written at different times intentionally arranged by the author not according to the order of composition but to the chronological growth of the subject, from early childhood to the Nobel prize award. Until the period when autobiography started to be recognized as a specific genre with its own rules, this work was resorted to as a support for the study of the author’s production or as a key to discovering his life, disregarding the fact that autobiographical writing is not the narration of a life, but rather a narrative of the self as seen from the present moment of writing. Yeats’s Autobiographies is the narrative of how he struggled to shape his own personal identity as well as the identity of the nation. Life stories flourished in the Revival and post-Revival periods in Ireland, thus testifying to a widely shared belief in the correspondence of individual and national destiny. Along with collective drives, personal reasons also compelled him to look back and write his own autobiography. The author managed to provide a text in which everything, from syntactic to linguistic choices, from his treatment of time and places to his presentation of friends and rivals, combines to give a composite portrait of himself from early expectations to final achievement.

Left-wing splinter parties in the Weimar Republic
Creators: name: Miller, Frederick Alfred
Publisher: name: University of British Columbia
Year: 2010

description: This study deals with left-wing splinter parties which were in existence in Germany between 1918 and 1933. In 1918 the Second Empire collapsed, the Kaiser abdicated, and the imperial government resigned. Only the socialists were relatively strong enough and, in the eyes of the public and the victorious Allies, unblemished enough to take command of the state. At this historical moment, however, the socialists were divided. The chance to install socialism in Germany was lost due to the bitter fighting among the three principal left-wing parties. The divisions in the socialist camp, which had started earlier, but which broke into open warfare at the end of the Great War, were intensified by the crises the Weimar Republic faced and led to a great number of splinter parties. Chapter One provides the background. It concentrates on some of the problems that the SPD and the KPD faced before Hitler's take-over. Chapter Two discusses the emergence of splinter groups. It traces each splinter group from its origin inside a larger party, its evolution,aand its decline. The Third Chapter examines the programs, platforms, and ideologies of the splinter parties. It concentrates on their political and economic demands. It also deals with their views on fascism and the methods they adopted to cope with the menace presented by the rise of Hitler's NSDAP. The Fourth Chapter is devoted to structure and organization. The parliamentary as well as the non parliamentary activities of the splinter parties are discussed. It examines their involvement in organizations like the trade unions and affiliated youth groups. Some of the major publications of the splinter parties are listed here. The Conclusion assesses the reasons for the failure of the splinter parties. Splinter parties were both, symptoms and victims of the turbulent times of the Weimar Republic. They were not the cause of Hitler's victory. Their importance lies not in the Impact they had on Weimar, but in what they show about Weimar Germany. They reflected in a microscopic way the insecurity, the mistrust, the social decay, the social and political mobility and unrest, the countless crises, and the blind and desperate search for something better.
Derivation of the time dependent Gross-Pitaevskii equation without positivity condition on the interaction

description: Using a new method it is possible to derive mean field equations from the microscopic $N$ body Schrödinger evolution of interacting particles without using BBGKY hierarchies. In this paper we wish to analyze scalings which lead to the Gross-Pitaevskii equation which is usually derived assuming positivity of the interaction. The new method for dealing with mean field limits presented in [6] allows us to relax this condition. The price we have to pay for this relaxation is however that we have to restrict the scaling behavior to $β<1/3$ and that we have to assume fast convergence of the reduced one particle marginal density matrix of the initial wave function $μ^{Ψ_0}$ to a pure state $|ϕ_0>

description: Liquid Argon Time Projection Chamber detectors are well suited to study neutrino interactions, and are an intriguing option for future massive detectors capable of measuring the parameters that characterize neutrino oscillations. These detectors combine fine-grained tracking with calorimetry, allowing for excellent imaging and particle identification ability. In this talk the details of the MicroBooNE experiment, a 175 ton LArTPC which will be exposed to Fermilab's Booster Neutrino Beamline starting in 2011, will be presented. The ability of MicroBooNE to differentiate electrons from photons gives the experiment unique capabilities in low energy neutrino interaction measurements.

description: Filmopoli was called the city in 1914, the same year of the masterpiece of Giovanni Pastrone Cabiria, whit the collaboration of D’Annunzio. Torino was at that time the capital of the cinematographic industry in Italy. Two world wars changed a lot the economy of the country and the relationship between reality and movies: the look of cinema goes directly to the city and the industry of realism production moved to Rome. Torino in the cinematographic imaginary is the city of Fiat but from ninety she is trying to propose a new face: the city of cinema. The Mole, the most important building and the symbol of the city is from 2000 The National Museum of Cinema.
