description: We consider the superstable cycles of the Q-state Potts (QSP) and the three-site interaction antiferromagnetic Ising (TSAI) models on recursive lattices. The rational mappings describing the models' statistical properties are obtained via the recurrence relation technique. We provide analytical solutions for the superstable cycles of the second order for both models. A particular attention is devoted to the period three window. Here we present an exact result for the third order superstable orbit for the QSP and a numerical solution for the TSAI model. Additionally, we point out a non-trivial connection between bifurcations and superstability: in some regions of parameters a superstable cycle is not followed by a doubling bifurcation. Furthermore, we use symbolic dynamics to understand the changes taking place at points of superstability and to distinguish areas between two consecutive superstable orbits.

description: We analyze the asymptotic performance of nonbinary spatially-coupled low-density parity-check (SC-LDPC) code ensembles defined over the general linear group on the binary erasure channel. In particular, we prove threshold saturation of belief propagation decoding to the so called potential threshold, using the proof technique based on potential functions introduced by Yedla \textit{et al.}, assuming that the potential function exists. We rewrite the density evolution of nonbinary SC-LDPC codes in an equivalent vector recursion form which is suited for the use of the potential function. We then discuss the existence of the potential function for the general case of vector recursions defined by multivariate polynomials, and give a method to construct it. We define a potential function in a slightly more general form than one by Yedla \textit{et al.}, in order to make the technique based on potential functions applicable to the case of nonbinary LDPC codes. We show that the potential function exists if a solution to a carefully designed system of linear equations exists. Furthermore, we show numerically the existence of a solution to the system of linear equations for a large number of nonbinary LDPC code ensembles, which allows us to define their potential function and thus prove threshold saturation.

description: We study the quantum melting of quasi-one-dimensional lattice models in which the dominant energy scale is given by a repulsive dipolar interaction. By constructing an effective low-energy theory, we show that the melting of crystalline phases can occur into two distinct liquid phases, having the same algebraic decay of density-density correlations, but showing a different non-local correlation function expressing string order. We present possible experimental realizations using ultracold atoms and molecules, introducing an implementation based on resonantly driven Rydberg atoms that offers additional benefits compared to a weak admixture of the Rydberg state.

description: The long-distance transport of messenger RNAs (mRNAs) has been shown to be important for several developmental processes in plants. A popular method for identifying travelling mRNAs is to perform RNA-Seq on grafted plants. This approach depends on the ability to correctly assign sequenced mRNAs to the genetic background from which they originated. The assignment is often based on the identification of single-nucleotide polymorphisms (SNPs) between otherwise identical sequences. A major challenge is therefore to distinguish SNPs from sequencing errors. Here, we show how Bayes factors can be computed analytically using RNA-Seq data over all the SNPs in an mRNA. We used simulations to evaluate the performance of the proposed framework and demonstrate how Bayes factors accurately identify graft-mobile transcripts. The comparison with other detection methods using simulated data shows how not taking the variability in read depth, error rates and multiple SNPs per transcript into account can lead to incorrect classification. Our results suggest experimental design criteria for successful graft-mobile mRNA detection and show the pitfalls of filtering for sequencing errors or focussing on single SNPs within an mRNA.
Creating the (School’s) Future. Imagination, Prediction and Argumentative Competence

Publisher: name: img journal
Year: 2022

description: This paper proposes notes and reflections on methodological strategies and qualitative outcomes of a teaching experiment that involved a class (5th year) of the primary school of the IC Galilei in Reggio Emilia. The work was carried out within a digitally augmented learning ecosystem capable of a) enabling synchronous and asynchronous interaction practices and b) facilitating cooperation and sharing at different levels of proximity (between teachers and students). In this context, efforts were made to enrich and develop pupils’ argumentative competence by working with images and especially by prodding their predictive imagination. Therefore, taking the evolution of technologies as a projectual (and cultural) horizon within which to try to imagine a plausible and desirable future, and conceiving –like Vygotskij –the imagination in terms of a creative and combinatory behaviour, we asked the children to ‘create’ a probable future. In other words, we asked them to give shape to the school of the future, starting with an analysis of the mistakes and intuitions that a group of artists at the end of the 19th century were able to make in an attempt to predict the year 2000 that the protagonists of this action-research project did not experience. Final objective: to develop in the children an argumentative and linguistic structure capable of supporting a lesson aimed at citizenship in which the pupils themselves would then share their idea of integrating digital technologies at school. The results collected made it possible to positively assess a second edition of the training course, which will see the adoption of a device –McLuhan’s Lost Tetrads– with which we will try to further encourage an exercise of imagination (and also of ar-gumentation) capable of designing sustainable contexts and ecosystems (of learning and beyond).

description: We report the discovery of 14 new transiting planet candidates in the Kepler field from the Planet Hunters citizen science program. None of these candidates overlapped with Kepler Objects of Interest (KOIs) at the time of submission. We report the discovery of one more addition to the six planet candidate system around KOI-351, making it the only seven planet candidate system from Kepler. Additionally, KOI-351 bears some resemblance to our own solar system, with the inner five planets ranging from Earth to mini-Neptune radii and the outer planets being gas giants; however, this system is very compact, with all seven planet candidates orbiting $\lesssim 1$ AU from their host star. A Hill stability test and an orbital integration of the system shows that the system is stable. Furthermore, we significantly add to the population of long period transiting planets; periods range from 124-904 days, eight of them more than one Earth year long. Seven of these 14 candidates reside in their host star's habitable zone.

Digital Video Effect. The Foundation of the Visual Imaginary in Italian Television in the 1980s
Creators: name: Rossi, Daniele
Publisher: name: img journal
Year: 2022

description: The article presents some reflections on the status of Italian television in the 1980s, a key period related to the transition from analog to digital images. A period marked by events, broadcasts, personalities and technologies that were at the beginning of the diffusion of computers that took place in Italy also thanks to the contribution of public and private television. The way and the timing of this transition have been analyzed considering some fundamental steps that the progress of information technology made in the 1980s also in television studios. While it is true that the introduction of graphic workstations radically expanded the graphic possibilities of the directors of TV, it is also true that ‘traditional’ visual art has made an important contribution to the esthetics and content of Italian television since the first television broadcasts. In this context, there are not many studies that have investigated the function of television in highlighting the role of information technologies in the construction of a new visual imaginary. To begin this analysis, we have analyzed, on the one hand, the programs, including radio programs, in which the electronic/digital language has interacted with that of television, and, on the other hand, some incursions on television programming by personalities already known for having explored experimental forms of hybridization between TV, art and computer.

description: Ensuring food security is affected by the saturation of agricultural products produced domestically and imported. The military actions in Ukraine have negatively affected the export logistics of Ukrainian agricultural products to third countries, thus posing a threat to food security. The aim of the study is to diversify the export logistics of Ukrainian agricultural products as a result of the blockade of seaports by using the capabilities of railway and vehicle transports, cross-border cooperation between Ukraine and the European Union countries. The study is based on an assessment of the volume of exports of Ukrainian agricultural products, an analysis of the geographical structure of logistics exports, and the border crossing of Ukrainian agricultural products by different types of transport. The paper describes diversified logistics routes for exporting Ukrainian agricultural products. Based on research results, identifies promising directions of support for the export logistics of Ukrainian agricultural products during martial law and ensuring food security.

description: We present a full pipeline for computing the medial axis transform of an arbitrary 2D shape. The instability of the medial axis transform is overcome by a pruning algorithm guided by a user-defined Hausdorff distance threshold. The stable medial axis transform is then approximated by spline curves in 3D to produce a smooth and compact representation. These spline curves are computed by minimizing the approximation error between the input shape and the shape represented by the medial axis transform. Our results on various 2D shapes suggest that our method is practical and effective, and yields faithful and compact representations of medial axis transforms of 2D shapes.

description: Consider a graph on $n$ uniform random points in the unit square, each pair being connected by an edge with probability $p$ if the inter-point distance is at most $r$. We show that as $n\to\infty$ the probability of full connectivity is governed by that of having no isolated vertices, itself governed by a Poisson approximation for the number of isolated vertices, uniformly over all choices of $p,r$. We determine the asymptotic probability of connectivity for all $(p_n,r_n)$ subject to $r_n=O(n^{-\varepsilon})$, some $\varepsilon >0$. We generalize the first result to higher dimensions and to a larger class of connection probability functions.

description: We monitored the quiescent thermal emission from neutron stars in low-mass X-ray binaries after active periods of intense activity in x-rays (outbursts). The theoretical modeling of the thermal relaxation of the neutron star crust may be used to establish constraints on the crust composition and transport properties, depending on the astrophysical scenarios assumed. We numerically simulated the thermal evolution of the neutron star crust and compared them with inferred surface temperatures for five sources: MXB 1659-29, KS 1731-260, EXO 0748-676, XTE J1701-462 and IGR J17480-2446. We find that the evolution of MXB 1659-29, KS 1731-260 and EXO 0748-676 can be well described within a deep crustal cooling scenario. Conversely, we find that the other two sources can only be explained with models beyond crustal cooling. For the peculiar emission of XTE J1701-462 we propose alternative scenarios such as residual accretion during quiescence, additional heat sources in the outer crust, and/or thermal isolation of the inner crust due to a buried magnetic field. We also explain the very recent reported temperature of IGR J17480-2446 with an additional heat deposition in the outer crust from shallow sources.

Real Estate and Marketing Rhetorics. The Rise of Heritage in the Face of Global Financialization
Creators: name: Pace, Michela
Publisher: name: img journal
Year: 2022

description: The contribution proposes to observe the inclusion of symbolic elements linked to the notion of heritage within the images used to promote domestic interiors in regeneration projects. This operation is conducted in two of the most important cities at the forefront of the housing crisis: London and Shanghai, and reveals remarkable parallels between Eastern and Western modes of communication and representation. The financialization of space, which had profoundly transformed the way we value, perceive and desire domestic intimacy opens up issues of space falsification, and distortion of the social models of reference. What these projects present us with are fictitious narratives that select not only materials, but also inhabitants, ambitions and social projections. What is new is the aggressiveness of the process linking the construction of spaces and the shaping of the subject, and the enhanced use of references to cultural elements able to secure economic returns. Their reassuring character stabilizes the perception of investment, forcing us to reflect on how we shape a specific idea of the city through images, and for whom we do so.

When a Picture Is Worth a Thousand Words: Using Image-Based Research Methods in Vulnerable Populations As a Culturally Sensitive Approach
Creators: name: Pepe, Alessandro
Publisher: name: img journal
Year: 2022

description: Image-based approaches –visual story-telling, photo-elicitation method, photo-walking, visual auto-ethnography– have been utilized as a novel exploratory tool in psychology and social science for examining visual identities, life histories, and other collective elements of local cultures. Visual and image-based methodologies held significant promise for building bottom-up participatory research designs for inquiries, particularly on vulnerable or disadvantaged individuals and groups. However, due to methodological difficulties, image-based research has maintained a restricted standing within the ‘traditional’ word-based oriented landscape of qualitative paradigms. The terrain addressed by the current paper includes various applications of image-based techniques as applied in vulnerable groups, as determined by some examples of recent literature. The key findings indicated an original galaxy of empirically based methodologies that may be utilized to incorporate more ‘traditional’ quantitative, qualitative, and mixed-method designs. Finally, implications from the practical application of this methodological design were discussed, notably in terms of decolonization of research techniques and ethical issues to guide practitioners’ research in challenging circumstances and vulnerable people.

Silent Poetry. Images of Gesturing Across the Arts. Pretexts and Thoughts on a Language of Great Educational Potential
Creators: name: De Nicola, Alessandra
Publisher: name: img journal
Year: 2022

description: The claim –attributed to Leonardo da Vinci– that “painting is mute poetry and poetry is blind painting”, authoritatively sums up the topic of this paper. Unlike literary languages, figurative visual arts draw on body language as a medium comprising expressions, postures, gestures, and signs representing gestures. Based on a conceptualization of gesticulation as a universally intelligible form of communication, we examine dictionaries of gesticulatory movements such as that developed by Bruno Munari or the choreographic projects of Virgilio Sieni, which are both rooted in the transposition of movement into images. In choreography, the act of transposing into images, conventionally signs or drawings, is termed notation and is the instrument via which artistic projects are communicated to dancers and handed down to posterity. It involves marking out an idea, knowledge, or simply a state of mind, fixing it on paper by means of a gesture. The nature of gesturing as a medium and a tool for immediate transposition underpins its valuable role in the field of education.

description: In a trans-scalar perspective, the Bicocca district extends from the local NIL (Nucleo di Identità Locale) to part of Municipality 9, Sesto San Giovanni and Cinisello Balsamo. Recently, the University of Milan-Bicocca, as regards to the so-called ‘terza missione’, has remarked its role as a key-pole for the surrounding area by proposing research, educational (and orientation) activities, as well as institutional initiatives based in this post-industrial area of Milan. Within this scenario, our group was in charge of design-ing a project leading to an artistic image representing the district users’ sense of place. By combining geography of perception, urban sociology, participatory design and the flânerie approaches, we planned a working process starting from the ‘subjective production of images’ by the district’s users and inhabitants. The project was structured in two phases: (1) December 2020 – January 2021: we organised two workshops by inviting groups of students, teachers and shop owners and working on their mental maps to construct a final image resulting from the two teams’ negotiation processes. The reading of the maps was initially inspired by the categories identified by Kevin Lynch (1962) and then moved on to a process of co-construction of a collective image; (2) March 2021: we shared the visual body with a professional illustrator (Carlo Stanga) entrusted with the mandate to translate the images into an artistic product. The essay discusses the visual representation of users’ sense of place and the potential legacy upon communication strategies, way-findings tools and education projects.

description: Energy efficient routing in wireless sensor networks has attracted attention from researchers in both academia and industry, most recently motivated by the opportunity to use SDN (software defined network)-inspired approaches. These problems are NP-hard, with algorithms needing computation time which scales faster than polynomial in the problem size. Consequently, heuristic algorithms are used in practice, which are unable to guarantee optimally. In this short paper, we show proof-of-principle for the use of a quantum annealing processor instead of a classical processor, to find optimal or near-optimal solutions very quickly. Our preliminary results for small networks show that this approach using quantum computing has great promise and may open the door for other significant improvements in the efficacy of network algorithms.

Cultural Expression: ‘Artistic’ or ‘Social’ Competence? Image Creativity in Young Adults Aspiring to Become Primary Level Teachers in Italian-Speaking Switzerland
Creators: name: Bottinelli Montandon, Mario
Publisher: name: img journal
Year: 2022

description: Two different cohorts of young adults, as a function of their access to Teacher training program for pre-primary and primary teachers in the Canton of Ticino (CH), attended in 2021 and 2022 a weeklong art workshop at the Department of Education and Learning of SUPSI (DFA). Framed within an annual training course, these intensive ateliers involved graphic, pictorial and plastic artistic research focusing on the theme ‘Art and War’, mobilizing the potential of the artwork to arouse not only emotional reactions, but also generative on a cognitive level, in order to develop reflective-critical thinking and creative thinking. Technical-expressive and representational competences have been placed in the foreground, activating strategies of figurative-abstract expression on the two-dimensional surface or in three dimensions. The article approach can be traced to the perspective of the case study and it is based on the resources (knowledge, skills and attitudes) referred to in Key competence 8 for lifelong learning, Cultural awareness and expression competence (European Council Recommendation of 22 May 2018). The project is intended to verify the status of both the image and visual culture in the transition between upper secondary and university of teacher education for the school system of the Italian-speaking Canton of Switzerland.

description: The multivariate Meixner polynomials are shown to arise as matrix elements of unitary representations of the $SO(d,1)$ group on oscillator states. These polynomials depend on $d$ discrete variables and are orthogonal with respect to the negative multinomial distribution. The emphasis is put on the bivariate case for which the SO(2,1) connection is used to derive the main properties of the polynomials: orthogonality relation, raising/lowering relations, generating function, recurrence relations and difference equations as well as explicit expressions in terms of standard (univariate) Krawtchouk and Meixner polynomials. It is explained how these results generalize directly to $d$ variables.

description: Based on the concept of ‘interpretive community’, it is possible to trace how humans can become interpreters (or decoders) of their own reality through, say, written excerpts and architectural works. This chapter is intended, therefore, to report on an interpretive-community workshop where students of three different disciplines (namely, Architecture, Sociology and English Studies) were assigned specific chapters of literary works with the goal of making a collective interpretation through a process of rewriting and restoring architecture. These projects allow students (or any participant, in fact) in their recognition of salient concepts that are not necessarily ascribed to a specific domain; for instance, the understanding of architecture not solely as a construction process, but as a mechanism intended to protect traces of life that are naturally perceived through narration and the use of metaphors.

Rainbows Between Art and Science. An Unconventional Analysis
Creators: name: Bortot, Alessio
Publisher: name: img journal
Year: 2022

description: What do have in common a friar lived in the 17th century, a contemporary American artist of the Land Art movement and an Italian structural engineer popular between the two World Wars? The answer can be certainly found in the common scientific approach of the three authors, but more precisely in their shared passion for the natural phenomenon of rainbow. This paper focuses on the contextualization of studies related to this atmospheric phenomenon starting from the classical period – considering its depictions in the history of science and art. Between the protagonists of this story, whose approaches go from aesthetic researches to natural philosophy, we can find the friar Emmanuel Maignan (1601-1676): a scholar of optics who was the author of one of the most important gnomonic treatises in the Baroque period. Since 1980 the artist Charles Ross has used big glass prisms –precisely oriented– to project the chromatic spectrum within architectural scale installations. Then, in the early decades of the 20th century the engineer Arturo Danusso (1880-1968) developed a method to evaluate the tension stress of the reinforced concrete structures based on photoelasticity. In addition to the examination of the heterogeneous uses of rainbow in art and science, this paper also intends to focus on the relationship between light and optics intended as a ‘universal method’ to study natural phenomena over the centuries.

description: Employing scalar QCD we study the gluon emission of heavy quarks created by the interaction with light quarks considered as dynamical scattering centers. We develop approximation formulas for the high energy limit and study when the full calculation reaches this high energy limit. For zero quark masses and in the high energy limit our model reproduces the Gunion-Bertsch results. We justify why scalar QCD represents a good approximation to the full QCD approach for the energy loss of heavy quarks. In the regime of accessible phenomenology we observe that the emission at small transverse momentum (dead cone effect) is less suppressed than originally suggested. We also investigate the influence of a finite gluon mass on the discussed results.

description: We reexamine the massless spectrum of a heterotic string vacuum at large radius and present two results. The first result is to construct a vector bundle $\mathcal{Q}$ and operator $\overline{\mathcal{D}}$ whose kernel amounts to deformations solving `F-term' type equations. This resolves a dilemma in previous works in which the spin connection is treated as an independent degree of freedom, something that is not the case in string theory. The second result is to utilise the moduli space metric, constructed in previous work, to define an adjoint operator $\overline{\mathcal{D}}^†$. The kernel of $\overline{\mathcal{D}}^†$ amounts to deformations solving `D-term' type equations. Put together, we show there is a vector bundle $\mathcal{Q}$ with a metric, a $\overline{\mathcal{D}}$ operator and a gauge fixing (holomorphic gauge) in which the massless spectrum are harmonic representatives of $\overline{\mathcal{D}}$. This is remarkable as previous work indicated the Hodge decomposition of massless deformations were complicated and in particular not harmonic except at the standard embedding.

The Representation of Space As a Narrative Language in Videogames
Creators: name: Attademo, Greta
Publisher: name: img journal
Year: 2022

description: The research examines the videogame as a new form of visual narration, in which the story is constructed not only by the designer's authorial intentions, but also by the interpretation of the player, who moves and acts in the gamespace. The space, therefore, can assume a central narrative role, helping the player in the construction of meanings necessary for the understanding of the story. The aim of this research is to analyse the representation of space as a narrative language in videogames, examining how spatial suggestions become a formal and structural code of visual signs, able to emphasize tones and atmospheres and/or express emotional values. The survey methodology includes a comparative analysis of videogame spaces, starting from the main types of narratives: realistic, verisimilar and unrealistic; this distinction allows to identify three macro-groups of spatial representations, having specific and defined characteristics. This research underlines how the scientific area of representation can contribute significantly to the study of videogame, understood as a narrative form in which the drawing of the space is applied as an irreplaceable modality for the construction of a visual code of thought.

description: Gaussian boson sampling is a model of photonic quantum computing that has attracted attention as a platform for building quantum devices capable of performing tasks that are out of reach for classical devices. There is therefore significant interest, from the perspective of computational complexity theory, in solidifying the mathematical foundation for the hardness of simulating these devices. We show that, under the standard Anti-Concentration and Permanent-of-Gaussians conjectures, there is no efficient classical algorithm to sample from ideal Gaussian boson sampling distributions (even approximately) unless the polynomial hierarchy collapses. The hardness proof holds in the regime where the number of modes scales quadratically with the number of photons, a setting in which hardness was widely believed to hold but that nevertheless had no definitive proof. Crucial to the proof is a new method for programming a Gaussian boson sampling device so that the output probabilities are proportional to the permanents of submatrices of an arbitrary matrix. This technique is a generalization of Scattershot BosonSampling that we call BipartiteGBS. We also make progress towards the goal of proving hardness in the regime where there are fewer than quadratically more modes than photons (i.e., the high-collision regime) by showing that the ability to approximate permanents of matrices with repeated rows/columns confers the ability to approximate permanents of matrices with no repetitions. The reduction suffices to prove that GBS is hard in the constant-collision regime.

description: This paper studies multiuser random coding techniques for channel coding with a given (possibly suboptimal) decoding rule. For the mismatched discrete memoryless multiple-access channel, an error exponent is obtained that is tight with respect to the ensemble average, and positive within the interior of Lapidoth's achievable rate region. This exponent proves the ensemble tightness of the exponent of Liu and Hughes in the case of maximum-likelihood decoding. An equivalent dual form of Lapidoth's achievable rate region is given, and the latter is shown to extend immediately to channels with infinite and continuous alphabets. In the setting of single-user mismatched decoding, similar analysis techniques are applied to a refined version of superposition coding, which is shown to achieve rates at least as high as standard superposition coding for any set of random-coding parameters.
