Subjects: religious education, augmented reality, authentic learning environment

description: The research of AR –technology in learning has indicated promising results, such as increased content understanding and student motivation. However, difficulties are reported as well, for example attention tunneling and usability difficulties. (for a review, see Radu 2014) Religious buildings offer a rich and authentic environment for learning about religion and understanding the surrounding culture. In an experiment with elementary school pupils (age 11-12) we wanted to explore the possibilities of augmented reality in creating a holistic learning environment in a church. Augmented reality proved a versatile tool for learning about church, biblical texts and doctrinal contents as well as learning of 21st century skills. The experiment also pinpointed challenges that need to be taken into account when designing augmented reality learning environments in a church.

description: Abstract: Brain’s modular connectivity gives this organ resilience and adaptability. The ageing process alters the organised modularity of the brain and these changes are further accentuated by neurodegeneration, leading to disorganisation. To understand this further, we analysed modular variability—heterogeneity of modules—and modular dissociation—detachment from segregated connectivity—in two ageing cohorts and a mixed cohort of neurodegenerative diseases. Our results revealed that the brain follows a universal pattern of high modular variability in metacognitive brain regions: the association cortices. The brain in ageing moves towards a segregated modular structure despite presenting with increased modular heterogeneity—modules in older adults are not only segregated, but their shape and size are more variable than in young adults. In the presence of neurodegeneration, the brain maintains its segregated connectivity globally but not locally, and this is particularly visible in dementia with Lewy bodies and Parkinson’s disease dementia; overall, the modular brain shows patterns of differentiated pathology.

description: A conformal metric $g$ with constant curvature one and finite conical singularities on a compact Riemann surface $Σ$ can be thought of as the pullback of the standard metric on the 2-sphere by a multi-valued locally univalent meromorphic function $f$ on $Σ\backslash \{{\rm singularities}\}$, called the {\it developing map} of the metric $g$. When the developing map $f$ of such a metric $g$ on the compact Riemann surface $Σ$ has reducible monodromy, we show that, up to some M{\" o}bius transformation on $f$, the logarithmic differential $d\,(\log\, f)$ of $f$ turns out to be an abelian differential of 3rd kind on $Σ$, which satisfies some properties and is called a {\it character 1-form of} $g$. Conversely, given such an abelian differential $ω$ of 3rd kind satisfying the above properties, we prove that there exists a unique conformal metric $g$ on $Σ$ with constant curvature one and conical singularities such that one of its character 1-forms coincides with $ω$. This provides new examples of conformal metrics on compact Riemann surfaces of constant curvature one and with singularities. Moreover, we prove that the developing map is a rational function for a conformal metric $g$ with constant curvature one and finite conical singularities with angles in $2π\,{\Bbb Z}_{>1}$ on the two-sphere.
description: Substantially revised. In particular, the definition of abelian metric is replaced by that of reducible metric. Comments welcomed. Submitted
The parameterized space complexity of model-checking bounded variable first-order logic

description: The parameterized model-checking problem for a class of first-order sentences (queries) asks to decide whether a given sentence from the class holds true in a given relational structure (database); the parameter is the length of the sentence. We study the parameterized space complexity of the model-checking problem for queries with a bounded number of variables. For each bound on the quantifier alternation rank the problem becomes complete for the corresponding level of what we call the tree hierarchy, a hierarchy of parameterized complexity classes defined via space bounded alternating machines between parameterized logarithmic space and fixed-parameter tractable time. We observe that a parameterized logarithmic space model-checker for existential bounded variable queries would allow to improve Savitch's classical simulation of nondeterministic logarithmic space in deterministic space $O(\log^2n)$. Further, we define a highly space efficient model-checker for queries with a bounded number of variables and bounded quantifier alternation rank. We study its optimality under the assumption that Savitch's Theorem is optimal.

description: The similarities between Hartree-Fock (HF) theory and the density-matrix renormalization group (DMRG) are explored. Both methods can be formulated as the variational optimization of a wave-function ansatz. Linearization of the time-dependent variational principle near a variational minimum allows to derive the random phase approximation (RPA). We show that the non-redundant parametrization of the matrix product state (MPS) tangent space [J. Haegeman et al., Phys. Rev. Lett. 107, 070601 (2011)] leads to the Thouless theorem for MPS, i.e. an explicit non-redundant parametrization of the entire MPS manifold, starting from a specific MPS reference. Excitation operators are identified, which extends the analogy between HF and DMRG to the Tamm-Dancoff approximation (TDA), the configuration interaction (CI) expansion, and coupled cluster theory. For a small one-dimensional Hubbard chain, we use a CI-MPS ansatz with single and double excitations to improve on the ground state and to calculate low-lying excitation energies. For a symmetry-broken ground state of this model, we show that RPA-MPS allows to retrieve the Goldstone mode. We also discuss calculations of the RPA-MPS correlation energy. With the long-range quantum chemical Pariser-Parr-Pople Hamiltonian, low-lying TDA-MPS and RPA-MPS excitation energies for polyenes are obtained.

description: We present a coalescent process where three particles merge at each coagulation step. Using a random walk representation, we prove duality with a fragmentation process, whose fragmentation law we specify explicitly. Furthermore, we give a second construction of the coalescence in terms of random binary forests and study asymptotic properties. Starting from N particles of unit mass, we obtain under an appropriate rescaling when N tends to infinity a well-known binary coalescence, the so-called standard additive coalescent.

Subsumption Algorithms for Three-Valued Geometric Resolution

description: In our implementation of geometric resolution, the most costly operation is subsumption testing (or matching): One has to decide for a three-valued, geometric formula, if this formula is false in a given interpretation. The formula contains only atoms with variables, equality, and existential quantifiers. The interpretation contains only atoms with constants. Because the atoms have no term structure, matching for geometric resolution is hard. We translate the matching problem into a generalized constraint satisfaction problem, and discuss several approaches for solving it efficiently, one direct algorithm and two translations to propositional SAT. After that, we study filtering techniques based on local consistency checking. Such filtering techniques can a priori refute a large percentage of generalized constraint satisfaction problems. Finally, we adapt the matching algorithms in such a way that they find solutions that use a minimal subset of the interpretation. The adaptation can be combined with every matching algorithm. The techniques presented in this paper may have applications in constraint solving independent of geometric resolution.

description: We propose a way of reasoning about minimal and maximal values of the weights of transitions in a weighted transition system (WTS). This perspective induces a notion of bisimulation that is coarser than the classic bisimulation: it relates states that exhibit transitions to bisimulation classes with the weights within the same boundaries. We propose a customized modal logic that expresses these numeric boundaries for transition weights by means of particular modalities. We prove that our logic is invariant under the proposed notion of bisimulation. We show that the logic enjoys the finite model property and we identify a complete axiomatization for the logic. Last but not least, we use a tableau method to show that the satisfiability problem for the logic is decidable.

description: Negotiations are a formalism for describing multiparty distributed cooperation. Alternatively, they can be seen as a model of concurrency with synchronized choice as communication primitive. Well-designed negotiations must be sound, meaning that, whatever its current state, the negotiation can still be completed. In earlier work, Esparza and Desel have shown that deciding soundness of a negotiation is Pspace-complete, and in Ptime if the negotiation is deterministic. They have also extended their polynomial soundness algorithm to an intermediate class of acyclic, non-deterministic negotiations. However, they did not analyze the runtime of the extended algorithm, and also left open the complexity of the soundness problem for the intermediate class. In the first part of this paper we revisit the soundness problem for deterministic negotiations, and show that it is Nlogspace-complete, improving on the earlier algorithm, which requires linear space. In the second part we answer the question left open by Esparza and Desel. We prove that the soundness problem can be solved in polynomial time for acyclic, weakly non- deterministic negotiations, a more general class than the one considered by them. In the third and final part, we show that the techniques developed in the first two parts of the paper can be applied to analysis problems other than soundness, including the problem of detecting race conditions, and several classical static analysis problems. More specifically, we show that, while these problems are intractable for arbitrary acyclic deterministic negotiations, they become tractable in the sound case. So soundness is not only a desirable behavioral property in itself, but also helps to analyze other properties.

description: We consider a topological space with its subbase which induces a coding for each point. Every second-countable Hausdorff space has a subbase that is the union of countably many pairs of disjoint open subsets. A dyadic subbase is such a subbase with a fixed enumeration. If a dyadic subbase is given, then we obtain a domain representation of the given space. The properness and the strong properness of dyadic subbases have been studied, and it is known that every strongly proper dyadic subbase induces an admissible domain representation regardless of its enumeration. We show that every locally compact separable metric space has a strongly proper dyadic subbase.

description: Since it was realized that the Curry-Howard isomorphism can be extended to the case of classical logic as well, several calculi have appeared as candidates for the encodings of proofs in classical logic. One of the most extensively studied among them is the $λμ$-calculus of Parigot. In this paper, based on the result of Xi presented for the $λ$-calculus Xi, we give an upper bound for the lengths of the reduction sequences in the $λμ$-calculus extended with the $ρ$- and $θ$-rules. Surprisingly, our results show that the new terms and the new rules do not add to the computational complexity of the calculus despite the fact that $μ$-abstraction is able to consume an unbounded number of arguments by virtue of the $μ$-rule.

description: We investigate the entanglement temperature of a small scale subsystem in low excited states by using holographic method. Especially, we study the entanglement entropy and entanglement temperature in higher derivative gravities which are considered as low thermal excitation of pure AdS gravity. We find that the entanglement entropy are related to the central charges of boundary CFT. The relation between the variance of entanglement entropy and energy of a small scale subsystem has been also obtained. Furthermore, the relation is consistent with the first law-like relation that is proposed by Phys. Rev. Lett. 110, 091602 (2013). Finally, we derive the formula of the variance of entanglement entropy in general excited states in gravity background with the Fefferman-Graham coordinates and the entanglement temperature can be figured out in special case.

description: We are systematically surveying all known and suspected Z Cam-type dwarf novae for classical nova shells. This survey is motivated by the discovery of the largest known classical nova shell, which surrounds the archetypal dwarf nova Z Camelopardalis. The Z Cam shell demonstrates that at least some dwarf novae must have undergone classical nova eruptions in the past, and that at least some classical novae become dwarf novae long after their nova thermonuclear outbursts, in accord with the hibernation scenario of cataclysmic binaries. Here we report the detection of a fragmented "shell", 3 arcmin in diameter, surrounding the dwarf nova AT Cancri. This second discovery demonstrates that nova shells surrounding Z Cam-type dwarf novae cannot be very rare. The shell geometry is suggestive of bipolar, conical ejection seen nearly pole-on. A spectrum of the brightest AT Cnc shell knot is similar to that of the ejecta of the classical nova GK Per, and of Z Cam, dominated by [NII] emission. Galex FUV imagery reveals a similar-sized, FUV-emitting shell. We determine a distance of 460 pc to AT Cnc, and an upper limit to its ejecta mass of ~ 5 x 10^{-5} Msun, typical of classical novae.

Lampi gamma: la durata non è tutto
Creators: Lorenzo Amati
Publisher: name: Media Inaf
Year: 2021

La scoperta di emissione di supernova associata al gamma-ray burst breve Grb 200826A sembra contraddire gli attuali scenari sull’origine di questi fenomeni estremi. Ma quanto possiamo fare davvero affidamento sulla durata osservata per individuare il progenitore di un Grb? Ospitiamo un editoriale sull’argomento di Lorenzo Amati, dirigente di ricerca all’Inaf di Bologna autore di un articolo “News & Views” pubblicato oggi sullo stesso numero di Nature Astronomy che riporta la scoperta
Fusioni gerarchiche di buchi neri
Creators: Valentina Guglielmo
Publisher: name: Media Inaf
Year: 2021

Mentre la maggior parte degli eventi di fusione fra oggetti estremi rilevati da Ligo e Virgo è prodotta da buchi neri cosiddetti “di prima generazione” formati dal collasso di stelle, altri potrebbero invece essere di seconda (o terza) generazione, in cui uno degli oggetti che fonde proviene già da una (o più) precedente fusione fra buchi neri. Un articolo pubblicato oggi su Nature Astronomy passa in rassegna tutti i risultati teorici, i modelli e gli eventi di onde gravitazionali rilevati e provenienti da fusioni gerarchiche di buchi neri di massa stellare

description: In programming models with a reversible semantics, computational steps can be undone. This paper addresses the integration of reversible semantics into process languages for communication-centric systems equipped with behavioral types. In prior work, we introduced a monitors-as-memories approach to seamlessly integrate reversible semantics into a process model in which concurrency is governed by session types (a class of behavioral types), covering binary (two-party) protocols with synchronous communication. The applicability and expressiveness of the binary setting, however, is limited. Here we extend our approach, and use it to define reversible semantics for an expressive process model that accounts for multiparty (n-party) protocols, asynchronous communication, decoupled rollbacks, and abstraction passing. As main result, we prove that our reversible semantics for multiparty protocols is causally-consistent. A key technical ingredient in our developments is an alternative reversible semantics with atomic rollbacks, which is conceptually simple and is shown to characterize decoupled rollbacks.

description: We explore a bijection between permutations and colored Motzkin paths that has been used in different forms by Foata and Zeilberger, Biane, and Corteel. By giving a visual representation of this bijection in terms of so-called cycle diagrams, we find simple translations of some statistics on permutations (and subsets of permutations) into statistics on colored Motzkin paths, which are amenable to the use of continued fractions. We obtain new enumeration formulas for subsets of permutations with respect to fixed points, excedances, double excedances, cycles, and inversions. In particular, we prove that cyclic permutations whose excedances are increasing are counted by the Bell numbers.

description: Η επιθεώρηση και συντήρηση του δικτύου μεταφοράς και διανομής ηλεκτρικής ενέργειας ήταν και συνεχίζει να αποτελεί σημαντική πρόκληση για την εξασφάλιση σταθερότητας. Η παρούσα εργασία εξετάζει την αποτελεσματικότητα εφαρμογής σύγχρονων μεθόδων επεξεργασίας εικόνας και τεχνητής νοημοσύνης και την εξέταση των περιορισμών τους προς διευκόλυνση της επιθεώρησης. Η προτεινόμενη μεθοδολογία, γραμμένη σε γλώσσα Python, αποτελείται από τρία στάδια. Στο πρώτο γίνεται εντοπισμός των αγωγών μέσω ενός νευρωνικού δικτύου εκπαιδευμένου για τη συγκεκριμένη εφαρμογή. Στο δεύτερο στάδιο γίνεται προσπάθεια ανίχνευσης της τραβέρσας, αποκλειστικά στα κομμάτια της εικόνας που υπάρχουν αγωγοί. Το φίλτρο Gabor επιτρέπει τον εντοπισμό της σε διάφορες διευθύνσεις φιλτράροντας την εικόνα με αντίστοιχο kernel. Στο τρίτο και τελευταίο στάδιο, προτείνονται δύο επιμέρους μεθοδολογίες για τον εντοπισμό των μονωτήρων. Η μία βασίζεται σε φιλτράρισμα με μορφολογικούς συντελεστές και η δεύτερη στην εκπαίδευση ενός νευρωνικού δικτύου για τον εντοπισμό του σώματος του μονωτήρα. Τέλος, αντιστοιχούνται τα εντοπισμένα pixels στην εικόνα υπέρυθρου φάσματος για την εξαγωγή της θερμοκρασίας καθενός μονωτήρα και την αναζήτηση για σφάλμα.
description: The inspection and maintenance of the electricity transmission and distribution network has been and continues to be a major issue to ensure its stability. This paper examines the effectiveness of modern methods of image processing and artificial intelligence and also examines their limitations for facilitating inspection. The proposed methodology, written in Python, consists of three stages. The first locates the powerlines through a neural network trained for the specific application. In the second stage, an attempt is made to detect the crossarms, exclusively in the parts of the image where powerlines have been detected. The Gabor filter allows the crossarm to be located in different directions by filtering the image with a corresponding kernel. In the third and final stage, two separate methodologies are proposed to detect the insulators. One is based on morphological filtering and the other on training a neural network to locate the body of the insulator. Finally, according to the detected pixels, the infrared image is searched to extract the temperature of each insulator and to detect errors if any.

A Recipe for State-and-Effect Triangles
Creators: name: Jacobs, Bart
Publisher: name: arXiv
Year: 2017
Subjects: subject: Logic in Computer Science (cs.LO)
subject: FOS: Computer and information sciences

description: In the semantics of programming languages one can view programs as state transformers, or as predicate transformers. Recently the author has introduced state-and-effect triangles which capture this situation categorically, involving an adjunction between state- and predicate-transformers. The current paper exploits a classical result in category theory, part of Jon Beck's monadicity theorem, to systematically construct such a state-and-effect triangle from an adjunction. The power of this construction is illustrated in many examples, covering many monads occurring in program semantics, including (probabilistic) power domains.

description: We consider a model of scalar field with non minimal kinetic and Gauss Bonnet couplings as a source of dark energy. Based on asymptotic limits of the generalized Friedmann equation, we impose restrictions on the kinetic an Gauss-Bonnet couplings. This restrictions considerable simplify the equations, allowing for exact solutions unifying early time matter dominance with transitions to late time quintessence and phantom phases. The stability of the solutions in absence of matter has been studied.
