description: Using methods from the theory of commutative graded Banach algebras, we obtain a generalization of the two dimensional Borsuk-Ulam theorem as follows: Let $ϕ:S^{2} \rightarrow S^{2}$ be a homeomorphism of order n and $λ\neq 1$ be an nth root of the unity, then for every complex valued continuous function $f$ on $S^{2}$ the function $\sum_{i=0}^{n-1} λ^{i}f(ϕ^{i}(x))$ must be vanished at some point of $S^{2}$. We give a generalization in term of action of compact groups. We also discuss about some noncommutative versions of the Borsuk- Ulam theorem

description: The Brownian motion of a light quantum particle in a heavy classical gas is theoretically described and a new expression for the friction coefficient is obtained for arbitrary temperature. At zero temperature it equals to the de Broglie momentum of the mean free path divided by the mean free path. Alternatively, the corresponding mobility of the quantum particle in the classical gas is equal to the square of the mean free path divided by the Planck constant. The Brownian motion of a quantum particle in a quantum environment is also discussed.

Dante’s Commedia, Islamic Rationalism,  and the Enumeration of the Sciences
Creators: name: Stone, Gregory B.
Publisher: name: Università degli Studi di Milano
Year: 2013

description: Lo studio sul rapporto tra Dante e la tradizione arabo-islamica è solitamente associato a due influenti studiosi del Novecento, Miguel Asín Palacios e Bruno Nardi. Nonostante le differenze, entrambi affermano che la struttura fondamentale della Commedia intende mostrare come la ragione naturale dell’uomo e la filosofia (Virgilio) siano inferiori alla rivelazione religiosa e alla teologia (Beatrice). Il contributo, affermando che l’architettura del poema dantesco si fonda sulla classificazione delle scienze formulata dai filosofi islamici (al-Fârâbî, Avicenna, e Averroè), intende mostrare che la struttura allegorica della commedia non è basata sulla distinzione tra filosofia e teologia ma sulla distinzione, tutta interna alla filosofia, tra praxis e theoria. Come i filosofi razionalisti, Dante nega che ci sia una forma di conoscenza più elevata che non sia raggiungibile attraverso la dimostrazione e il ragionamento filosofico ma solo attraverso il discorso religioso rivelato (una posizione esemplificata dall’interpretazione che Avicenna fa del mi‘râj o Ascensione di Muhammad). Questa classificazione islamica delle scienze può aiutare a rivedere il ruolo giocato da Statius e Matelda nell’allegoria dantesca e identificare con maggior precisione il luogo della religione (che appartiene, sorprendentemente, più a Virgilio nel Purgatorio che a beatrice in Paradiso).

The study of Dante in relation to the medieval Arabo-Islamic tradition is most notably associated with two influential twentieth-century scholars, Miguel Asín Palacios and Bruno Nardi. Despite differences, both hold that Commedia’s fundamental structure aims to show natural human reason and philosophy (Virgil) falling short of religious revelation and theology (Beatrice). This essay, arguing that the architectural design of Dante’s poem is based on the classification of the philosophical sciences formulated by the Islamic rationalist philosophers (al-Fârâbî, Avicenna, and Averroes), shows that Commedia’s allegorical structure is not based upon the distinction between philosophy and theology but rather upon a distinction within philosophy between praxis and theoria. Like the Islamic rationalist philosophers, Dante denies that there is a higher human knowledge unattainable through philosophical demonstration but accessible through revealed religious discourse (a position exemplified by Avicenna’s interpretation of Muhammad’s mi‘râj or Ascension). This Islamic classification of the sciences will also help us see the role played by Statius and Matelda in Dante’s allegory and to identify the locus of religion (which, surprisingly, belongs with Virgil in Purgatory rather than with Beatrice in Heaven).

A Thirteenth Century Composite Account  of Muhammad’s Visit to Paradise
Creators: name: Colby, Frederick S.
Publisher: name: Università degli Studi di Milano
Year: 2013

description: Il contributo sostiene che una versione lunga e composita del Viaggio notturno del profeta e della sua ascensione, attribuita a Ibn ‘Abbas attraverso una figura più tarda conosciuta come al-Bakri, è diventata molto popolare e largamente diffusa nel tredicesimo secolo. Qui si propone una traduzione del viaggio celeste di Muhammad (la visita al paradiso)  a partire da un importante manoscritto inedito di Istanbul copiato nella penisola araba verso la fine del tredicesimo secolo. Questa traduzione si propone come strumento per gli studiosi interessati alla tradizione islamica delle ascensioni celesti e per chi si occupa delle possibile influenze musulmane sull’opera di Dante. Nonostante non si dimostri che Dante avesse avuto accesso diretto a questa fonte nel momento in cui componeva la divina commedia, ci sono prove sufficienti che le versioni di questo racconto fossero diffuse in diverse parti del Mediterraneo, prima e durante la vita di Dante. L’autore fa propria la recente ipotesi interpretativa di Bencheikh che sottolinea il ruolo fondamentale della versione di Bakri del Mi’râj per la composizione dell’ormai noto Libro della Scala, tradotto in latino e lingua francese antico in al-Andalus nella seconda metà del tredicesimo secolo.

This article argues that a long and composite version of the narrative of Muhammad's night journey and ascension, one often ascribed to Ibn 'Abbas via a later figure known as al-Bakri, became especially popular and widely distributed in the thirteenth-century CE.  It offers a translation of the Tour of Paradise section from a particularly important unpublished Istanbul manuscript preserving this version, copied in the Arabian peninsula near the end of the thirteenth-century.  This translation could serve as a resource to scholars who are interested in the history of Islamic ascension narratives, and interested in the question of possible Muslim influences on Dante's Divine Comedy.  While the author of this article does not argue that Dante must have been aware of this particular manuscript as he composed his masterwork, he claims that there is enough evidence to suggest that versions of this narrative circulated in different parts of the Mediterranean before and during Dante's lifetime.  He supports the earlier conjecture by Bencheikh that the Bakri versions were likely foundational to the composition of the now famous "Book of Muhammad's Ladder" that was translated into Latin and Old French in al-Andalus / Spain in the second half of the thirteenth-century.

description: Tree-based machine learning models, such as decision trees and random forests, are one of the most widely used machine learning models primarily because of their predictive power in supervised learning tasks and ease of interpretation. Despite their popularity and power, these models have been found to produce unexpected or discriminatory behavior. Given their overwhelming success for most tasks, it is of interest to identify root causes of the unexpected and discriminatory behavior of tree-based models. However, there has not been much work on understanding and debugging tree-based classifiers in the context of fairness. We introduce FairDebugger, a system that utilizes recent advances in machine unlearning research to determine training data subsets responsible for model unfairness. Given a tree-based model learned on a training dataset, FairDebugger identifies the top-k training data subsets responsible for model unfairness, or bias, by measuring the change in model parameters when parts of the underlying training data are removed. We describe the architecture of FairDebugger and walk through real-world use cases to demonstrate how FairDebugger detects these patterns and their explanations.
Maometto personaggio nel contesto

Year: 2013

description: L’articolo offre un’analisi puntuale dei versi che Dante dedica a Maometto nel ventottesimo canto dell’Inferno, al fine di precisarne le finalità poetiche e ideologiche; il passo viene poi collocato nel contesto costituito dai numerosi riferimenti al profeta dell’Islam presenti nella letteratura italiana duecentesca e primo-trecentesca, qui raccolti, analizzati e organizzati in maniera puntuale. Gli elementi connotativi riconosciuti nell’episodio infernale e in altri riferimenti alla civiltà islamica che si leggono nel capolavoro dantesco, pur nella loro geniale eccezionalità artistica, risultano così coerentemente inseribili in un più vasto e articolato panorama culturale che emerge dalla ricerca, nel quale, all’ostilità per l’Islam inteso come entità religiosa e politica, si affianca la curiosità per il mondo musulmano percepito invece come comunità culturale, rilevabile anche presso fasce inaspettate del pubblico medievale.

This  paper analyses the episode of Muhammad in Dante’s Inferno, recognizing its poetical and ideological features in order to proceed with its insertion in the survey of references to the prophet detectable in the Italian literature of the Thirteenth and Fourteenth centuries. The study allows to identify the substantial coherence between Dante’s ideological opinions toward Islam and the positions about the same subject expressed in the other works of the vernacular literature of his time, showing a general rejection for religious and political Islam, but also the interest for Islam as cultural entity.

description: We obtain the equations of motions of the $f(T)$ theory considering the Lemaître-Tolman-Bondi's metric for a set of diagonal and non-diagonal tetrads. In the case of diagonal tetrads the equations of motion of the $f(T)$ theory impose a constant torsion or the same equations of the General Relativity, while in the case of non-diagonal set the equations are quite different from that obtained in GR. We show a simple example of an universe dominated by the matter for the two cases. The comparison of the mass in the non-diagonal case shows a sort of increased with respect to the diagonal one. We also perform two examples for the non-diagonal case. The first concerns a black hole solution of type Sshwarzschild which presents a temperature higher than that of Schwarzschild, and a black hole in a dust-dominated universe.

Manganese imaging with positron emission tomography, autoradiography, and magnetic resonance
Creators: name: Topping, Geoffrey John
Publisher: name: University of British Columbia
Year: 2014

description: Manganese is a magnetic resonance imaging (MRI) contrast agent for small animals that can provide a blood-flow-independent measure of neuronal activation. Established Mn MRI methods have limited ability to measure concentrations of Mn or details of its distribution in vivo, which limits their experimental power. Positron emission tomography (PET) can measure quantitative distributions in vivo in small animals of positron-emitting radionuclides such as Mn-52, although has poorer spatial resolution than MRI. Autoradiography (AR) can also measure quantitative distributions of Mn-52, in ex vivo brain tissue, with spatial resolution similar to MRI. This work has three primary goals: to develop and characterize Mn-52 as a radionuclide for PET in phantoms and in small animals, to develop a quantitative MRI method for measuring Mn concentration in the brain of small animals, and to validate the MRI results by comparisons with AR and PET. Mn-52 was produced by proton irradiation of natural Cr foil, isolated by column chromatography, and used as a PET tracer for the first time in phantoms and in vivo in rats. Mn-52 phantom image quality metrics were similar to F-18, an established PET radionuclide. After systemic administration in rats, Mn-52 accumulation was seen in bones, but little was seen in the brain, due to the blood-brain barrier. Direct injection into the lateral ventricle effectively delivers Mn-52 throughout the rat brain. Mn-52 AR images were acquired and used for comparison with MRI. MRI R1 relaxation rate maps of rat brain were acquired using a radiofrequency field strength independent inversion recovery Look-Locker sequence, and used to generate relaxation rate change and Mn concentration maps after Mn administration. These maps showed excellent quantitative agreement with PET and AR images of the same animal, confirming that MR R1 change accurately measures Mn concentration in rat brain in the range 0 to 0.1 mM, in the absence of other sources of R1 change. However, at some point above this concentration, measured R1 becomes inaccurate. Accordingly, Mn concentration mapping with MRI is a potentially useful tool to improve the experimental power of Mn-uptake imaging to assess neuronal activation.

description: Objective: The division of responsibility in vehicle-two-wheelers accidents reflects the extent to which different fault parties contributed to the occurrence of the accident, with significant differences in the injuries sustained by the riders in accidents where diverse parties were primarily responsible. We want to explore the difference in the severity of injury of riders in different fault parties of accidents so that we can make targeted protection improvements. Methods: In this study, three generalized ordered logit models were established for the total sample (n = 1204), the sample with drivers as the primary fault party (n = 607), and the sample with riders as the primary fault party (n = 597), respectively, to explore the differential impact factors on rider injury severity in vehicle-two-wheelers accidents involving different fault parties. Inter-group difference tests were conducted on the mean rider injury severity caused by differential factors in different accidents. Combining the impact effect trends and mean differences in the model, the differences in rider injury severity in accidents involving different fault parties were analyzed from the standpoints of human, vehicle, and road factors. Results: It was found that the effects of curve on injury severity was sheerly opposite in accidents with different fault parties and that factors, such as visual obstruction, road surface condition, gender, and helmet wearing differed in their effects on rider injury severity under different fault parties accidents. This reveals the driving tendencies and states of both parties in different environments. Conclusion: Based on the differential impact factor analysis and rider injury characteristics in accidents involving different fault parties, suggestions for improvement were made from the perspectives of road facilities, and safety awareness of drivers and riders, which are beneficial for improving rider safety and providing a theoretical reference for future regulations on liability allocation.

description: Bhargava and Shankar prove that as E varies over all elliptic curves over Q, the average rank of the finitely generated abelian group E(Q) is bounded. This result follows from an exact formula for the average size of the 2-Selmer group, which in turn follows from an asymptotic formula for the number of binary quartic forms over Z with bounded invariants. We explain their proof, as well as other arithmetic applications.

The construction in the second half of Section 4.1 of [BS15b] of a positive-density family of elliptic curves in which the root number is equidistributed is actually taken from p. 25 and Section 9 of Siman Wong's article [Won01]; we have edited our text to credit Wong with this discovery.

Dynamical analysis of sea breeze hodograph rotation in Sardinia
Creators: name: Moisseeva, Nadejda
Publisher: name: University of British Columbia
Year: 2014

description: This study investigates the diurnal evolution of sea-breeze rotation over an island in the mid- latitudes. Earlier research on sea-breezes in Sardinia shows that the onshore winds around various coasts of the island exhibit both the theoretically predicted clockwise rotation as well as seemingly anomalous anti-clockwise rotation. A non-hydrostatic fully compressible numerical model (WRF) is used to simulate wind fields on and around the island on previously-studied sea-breeze days and is shown to accurately capture the circulation on all coasts. Diurnal rotation of wind is examined and patterns of clockwise and anti-clockwise rotation are identified. A dynamical analysis is per- formed by extracting individual forcing terms from the horizontal momentum equations. Analysis of several regions around the island shows that the direction of rotation is a result of a complex interaction between near-surface and synoptic pressure gradient, Coriolis and advection forcings. An idealized simulation is performed over an artificial island with dramatically simplified topog- raphy, yet similar dimensions and latitude to Sardinia. Dynamical analysis of the idealized runs reveals a rather different pattern of hodograph rotation to the real Sardinia, yet similar underlying dynamics. The research provides new insights into the dynamics underlying sea-breeze hodograph rotation, especially in coastal zones with complex topography and/or coastline.
Quasiperiodicity in time evolution of the Bloch vector under the thermal Jaynes-Cummings model

description: We study a quasiperiodic structure in the time evolution of the Bloch vector, whose dynamics is governed by the thermal Jaynes-Cummings model (JCM). Putting the two-level atom into a certain pure state and the cavity field into a mixed state in thermal equilibrium at initial time, we let the whole system evolve according to the JCM Hamiltonian. During this time evolution, motion of the Bloch vector seems to be in disorder. Because of the thermal photon distribution, both a norm and a direction of the Bloch vector change hard at random. In this paper, taking a different viewpoint compared with ones that we have been used to, we investigate quasiperiodicity of the Bloch vector's trajectories. Introducing the concept of the quasiperiodic motion, we can explain the confused behaviour of the system as an intermediate state between periodic and chaotic motions. More specifically, we discuss the following two facts: (1) If we adjust the time interval $Δt$ properly, figures consisting of plotted dots at the constant time interval acquire scale invariance under replacement of $Δt$ by $sΔt$, where $s(>1)$ is an arbitrary real but not transcendental number. (2) We can compute values of the time variable $t$, which let $|S_{z}(t)|$ (the absolute value of the $z$-component of the Bloch vector) be very small, with the Diophantine approximation (a rational approximation of an irrational number).

Dante e l'Islam. La ripresa del dibattito storiografico sugli studi di Asin Palacios
Creators: name: Baccaro, Sabina

Year: 2013

description: Nel 1919 l’arabista spagnolo Don Miguel Asín Palacios dichiara in un’opera dirompente di aver rintracciato i modelli cui Dante si sarebbe realmente ispirato per l’elaborazione della sua Commedia in una serie di scritti arabo-islamici che narrano esperienze di viaggio nei regni dell’Oltretomba.

All’indomani della pubblicazione del rivoluzionario saggio La Escatologia musulmana en la Divina Comedia, diversi studiosi hanno contribuito ad alimentare un fervente dibattito i cui risvolti non cessano di sorprendere ancora oggi. Si procederà, pertanto, a delineare il quadro generale della critica dagli anni Cinquanta sino ai giorni nostri. Più specificamente, oggetto d’esame saranno lo scrupoloso lavoro di Enrico Cerulli, la produzione di intellettuali come Francesco Gabrieli, Umberto Bosco e Giorgio Levi della Vida, nonché la critica più recente che vanta interventi di illustri dantisti tra cui Carlo Saccone, Cesare Segre e Maria Corti. A conclusione sarà introdotto il lavoro di Ida Zilio-Grandi che ha rappresentato l’ultima tappa di questa rinnovata discussione in chiave islamica sulle fonti del capolavoro dantesco, sublime emblema del viaggio ultraterreno.

In 1919 Don Miguel Asín Palacios announced that he finally discovered the real models that inspired Dante’s Divine Comedy. In his essay, La Escatologia musulmana en la Divina Comedia, the Spanish arabist identified a series of Arab-Islamic written texts describing fully experiences of journey in the Afterworld.

Since the day after this publication, a large number of scholars animated a lively debate whose implications continue to amaze experts even today. Thus, an accurate picture of the literary criticism from the Fifties until today is presented hereunder. More specifically, the following excerpt examines the thorough research of Enrico Cerulli, the brilliant works of several intellectuals such as Francesco Gabrieli, Umberto Bosco and Giorgio Levi della Vida and the recent developments of the debate which claims as contributors distinguished Dante scholars like Carlo Saccone, Cesare Segre and Maria Corti. To conclude, the work of Ida Zilio-Grandi is introduced as the last step within the renewed discussion about the true sources of Dante’s masterpiece – sublime symbol of the afterlife journey– from an Islamic point of view.

description: We report on a photo-induced transient state of YBa2Cu2O6+x in which transport perpendicular to the Cu-O planes becomes highly coherent. This effect is achieved by excitation with mid-infrared optical pulses, tuned to the resonant frequency of apical oxygen vibrations, which modulate both lattice and electronic properties. Below the superconducting transition temperature Tc, the equilibrium signatures of superconducting interlayer coupling are enhanced. Most strikingly, the optical excitation induces a new reflectivity edge at higher frequency than the equilibrium Josephson plasma resonance, with a concomitant enhancement of the low frequency imaginary conductivity. Above Tc, the incoherent equilibrium conductivity becomes highly coherent, with the appearance of a reflectivity edge and a positive imaginary conductivity that increases with decreasing frequency. These features are observed up to room temperature in YBa2Cu2O6.45 and YBa2Cu2O6.5. The data above Tc can be fitted by hypothesizing that the light re-establishes a transient superconducting state over only a fraction of the solid, with a lifetime of a few picoseconds. Non-superconducting transport could also explain these observations, although one would have to assume transient carrier mobilities near 10^4 cm^2/(V.sec) at 100 K, with a density of charge carriers similar to the below Tc superfluid density. Our results are indicative of highly unconventional non-equilibrium physics and open new prospects for optical control of complex solids.

Gli studi di Enrico Cerulli su Dante
Creators: name: Celli, Andrea
Publisher: name: Università degli Studi di Milano
Year: 2013

description: Nel 1949 lo studioso di lingue semitiche Enrico Cerulli pubblicò un volume, intitolato Il “Libro della scala” e la questione delle fonti arabo-spagnole della Divina Commedia, che segnò gli studi danteschi, per lo meno per quanto riguarda il dibattito sulle fonti arabo-islamiche del medioevo europeo. Le ricerche di Cerulli su Dante si presentavano come una analisi di fatti di trasmissione culturale. Ma l’autore si era già affermato, nella prima parte della sua carriera, in un più controverso ambito di competenze: alto funzionario dell’amministrazione coloniale italiana e vice-governatore dell’Africa Orientale Italiana, è stato rilevante studioso di lingue del Corno d’Africa, cioè le lingue delle colonie italiane. Questo saggio vuole connettere gli studi danteschi di Cerulli alle responsabilità coloniali e post-coloniali dell’autore, attraverso la ricostruzione della sua biografia intellettuale. Difatti, da queste ricerche Cerulli ricavò il concetto di unità della civiltà mediterranea, formula di evidente valore politico in rapporto all’Italia del secondo dopoguerra. Il saggio prova a offrire anche uno stato dell’arte del dibattito attuale sulle fonti arabe di Dante.

 In 1949, Enrico Cerulli, an Italian scholar of Ethiopic-Semitic languages, published a volume entitled The “Book of the Ladder” and the Problem of Divine Comedy’s Arabic-Spanish Sources, which was to become a landmark in the discussion on the knowledge held by medieval Europe of Arabic-Islamic culture. His investigation was an analysis of cases of cultural transmission. However, Cerulli had established himself during the first half of his career in a more controversial domain: he was a senior official of Italian colonial administration and he was already well known as an expert of Italian colonies’ languages and traditions. This essay, through a survey of Cerulli’s intellectual biography, aims to bridge his research on Dante and his involvement in colonial and post-colonial governmental decisions. In fact, Cerulli summarised the outcomes of his studies in the concept of unity of Mediterranean Civilisation: such a formula has undeniable political meaning in Italian secondo dopoguerra. The essay also offers a short state-of-the-art regarding current discussions on Arabic sources of Dante’s Middle Ages.

Le visiones occidentali anteriori alla Commedia e la tradizione dell’Isra’ wa’ l Mi‘râj. Intertestualità o poligenesi?
Creators: name: Piccoli, Maria
Publisher: name: Università degli Studi di Milano
Year: 2013

description: Scopo del saggio è confrontare alcune tra le principali visiones della letteratura occidentale – tra cui la Visio Pauli e la Commedia – e le diverse redazioni della tradizione islamica dell’ascensione celeste e viaggio oltremondano del profeta Muhammad (Isra’ wa-l mi’râj), nel tentativo di stabilire se le affinità, tematiche e strutturali, osservabili tra i due gruppi di testi siano frutto di semplice poligenesi o vadano piuttosto spiegate con rapporti di effettiva intertestualità.

Tra le visiones, la tradizione mirajica e la Commedia si instaura dunque un dialogo a tre voci, o di sinfonia, i cui temi principali si arricchiscono e si richiamano a vicenda. Dante, primo comparatista, è in grado di reinventare, armonizzandoli, elementi strutturali e tematici provenienti sia dalle visiones latine che dalla tradizione islamica del Isra’ wa’ l Mi‘râj.

The purpose of this essay is to make a confrontation between the main important visiones of the Occidental Literature – also the Visio Pauli and the Dante’s Commedia – anche the various redactions of the Islamic Isra’ wa-l mi’râj. The confrontation is in order to establish if the remarked affinities are just due to polygenesis or rather caused by concrete intertestuality.

Between the visiones, the mirajic tradition and the Commedia we are in front of a three voices dialogue: it’s like a symphony, in which the themes enriches themselves and, at least, the arrive to Dante for being harmonized. Dante is the first comparatist.

description: We discuss the process of transmutation of branes into Abelian magnetic flux on the worldvolume of $D9$ branes. This phenomenon is T-dual to the recombination of branes in the intersecting-brane description. In the low energy limit this can be described by a Higgs mechanism involving bifundamental scalars. The Abelian magnetic background arises as a consequence of the compactness of the internal space. Explicit (six-dimensional) examples based on the supersymmetric and the Brane Supersymmetry Breaking (BSB) \mathbb{T}^4/\mathbb{Z}_2 orientifold are analyzed.

description: Il contributo intende discutere alcune questioni legate alla diversa visione del profeta dell'Islam in una prospettiva interculturale. In particolare si tentano di evidenziare le radici del problema concentrandosi sullo contesto storico in cui la questione ha preso forma. Emerge una critica alla maggior parte degli studiosi arabi che, storicamente, hanno evitato di affrontare lo studio di fonti non musulmane che potessero proporre visioni contrastanti rispetto alle credenze religiose condivise. Il contributo ha affrontato quindi il problema della traduzione di opere letterarie occidentali in arabo, in particolare le opere in cui è implicata l’immagine del profeta dell'Islam: emerge una censura piuttosto diffusa che tende a omettere le parti considerate "offensive" per la sensibilità religiosa dei musulmani. La Divina Commedia di Dante Alighieri rappresenta il caso esemplare di questo atteggiamento. Obbiettivo del contributo è affrontare il concetto di diversità in modo costruttivo in modo da non nascondere i fatti attraverso la censura o la non conoscenza ma invocando un nuovo modo di confrontarsi nel contesto multiculturale.

This paper discusses the frequent intercultural problems related to the different cross-cultural vision of the prophet of Islam. In particular, the paper highlights the roots of the problem; in fact, focusing on the historical background of the problem is extremely important. Moreover, the paper delivered criticism to the majority of Arab scholars who, historically, seemed to lack the willingness to study non Muslim sources that have a contradicting vision to their believes. The paper tackled the issue of the translation of western literary works into Arabic, especially those that tackles the image of the prophet of Islam, where the Arabic translation usually skip any “offensive” part related to the image of the prophet. For example, The divine comedy of Dante Alighieri.  The paper tries to face the concept of diversity in constructive way, by never hiding the facts, as this can never be considered a solution, but a way to transform it into a very complex problem.

Il viaggio oltremondano del Profeta nell’iconografia musulmana

description: La pittura islamica e in particolare l’illustrazione dei manoscritti, opere a circolazione limitata e prevalentemente privata, ha avuto una notevole diffusione godendo del patrocinio delle corti. Alcune pitture, soprattutto quelle che illustrano l’Ascensione celeste del profeta Muhammad (mi’râj), ma anche le Storie dei Profeti, pitture datate al XIV e XV secolo, rappresentano l’uno e gli altri col volto scoperto. Solo relativamente tardi, in particolare nel mondo iranico, ma anche presso gli ottomani o i Moghul dell’India, il volto del Profeta diventa una convenzione iconografica. Un versetto coranico afferma che Dio parla all’uomo o per Rivelazione o dietro a un velame. Per questo nell’iconografia della pittura islamica si constata che il Profeta o altri personaggi possono figurare con il volto coperto da un velo. Questo segno di rispetto, col tempo, si trasformerà in parola e il sembiante del Profeta sarà reso calligraficamente.

Islamic painting and particularly miniature painting illustrating manuscripts, books restricted to few people and for personal use, had a considerable circulation thanks to the patronage of courts. Some paintings, chiefly those illustrating the heavenly Ascent of the prophet Muhammad (mi’râj),  but also Histories of Prophets, paintings dated to the XIV and XV century, show him and the others barefaced. Only fairly later, particularly in the iranian world, but also among Ottomans or the Moghuls of India, the face of the Prophet becomes an iconographic convention. According to a   Koranic verse God speaks to man either through Revelation of behind a veil. For this reason in the iconography of islamic painting the Prophet or other people may appear with the face covered by a veil. This sign of respect, in the course of time, changed  and the countenance of the Prophet was rendered in words, that is calligraphically.

description: P. Mormul has classified the singularities of special multi-flags in terms of "EKR class" encoded by sequences $j_1,\dots, j_k$ of integers (see [Singularity Theory Seminar, Warsaw University of Technology, Vol. 8, 2003, 87-100] and [Banach Center Publ., Vol. 65, Polish Acad. Sci., Warsaw, 2004, 157-178]). However, A.L. Castro and R. Montgomery have proposed in [Israel J. Math. 192 (2012), 381-427] a codification of singularities of multi-flags by RC and RVT codes. The main results of this paper describe a decomposition of each "EKR" set of depth $1$ in terms of RVT codes as well as characterize such a set in terms of configurations of an articulated arm. Indeed, an analogue description for some "EKR" sets of depth $2$ is provided. All these results give rise to a complete characterization of all "EKR" sets for $1\leq k\leq 4$.
La prigionia e la salvezza dell’anima da Avicenna a Suhrawardî: quali fonti?
Creators: name: Stella, Federico

description: In questo articolo verrà preso in esame il tema della prigionia dell’anima e della sua successiva liberazione, partendo da uno dei tre racconti visionari di Avicenna, intitolato Hayy Ibn Yaqzân e indagandone le fonti filosofiche. Si partirà dall’analisi del il mito della caverna di Platone e dell’interpretazione allegorica data ad esso dal filosofo al-Fārābī. Tenendo presente questa lettura, saranno sviluppate alcune riflessioni sull’oggetto e sul significato di questi racconti visionari: allegorie filosofiche sulla natura della conoscenza (interpretazione cui propendeva anche Suhrawardi nel Racconto dell’esilio a occidente riguardo a Hayy Ibn Yaqzân), allegorie religiose di carattere gnostico sul tema della liberazione dell’anima dalla sua prigione terrena raffigurata dall’occidente e della sua conseguente salvezza, o un insieme di queste due possibili interpretazioni.

Sebbene il focus del contributo sia l’opera avicenniana si terrà conto anche dello scritto successivo di Suhrawardī, contenutisticamente analogo, ma con finalità diverse.

In this article I study the theme of imprisonment of the soul and its subsequent release, starting from one of the three visionary tales of Avicenna, entitled Ḥayy ibn Yaqẓān. I start  with the analysis of the possible sources of Islamic authors, such as the Plato’s myth of the cave and its allegorical interpretation given by the philosopher al-Fārābī.

I develop some thoughts about the Avicenna’s possible objectives in writing the visionaries tales: 1. the philosophical allegories about the nature of knowledge (in the “Tale of the exile in the West”, Suhrawardī seems to have this view), 2. the religious allegories with Gnostic character on the theme of the liberation of the soul from its earthly prison, represented by the West, and its consequent salvation, or 3. a combination of these two possible interpretations?

The article focuses on Avicenna and the philosophical sources that could have inspired his tales (Plato and al-Fārābī), and taking into account  Suhrawardī’s later writing, that has a similar content, but probably with different intentions.

description: We consider a model for random walks on random environments (RWRE) with random subset of Z^d as the vertices, and uniform transition probabilities on 2d points (two "coordinate nearest points" in each of the d coordinate directions). We give partial characterization of transience and recurrence in the different dimensions. Finally we prove Central Limit Theorem (CLT) for such random walks, under a condition on the distance between coordinate nearest points.

description: The rare secondary flavonol glycoside Sagittatoside A has much better in vivo bioactivities than epimedin A in Epimedii Folium. However, its current preparation methods are of low efficiency, with byproducts generated. The aim of this study was to establish a novel catalysis system for effective and convenient preparation of Sagittatoside A from epimedin A based on recyclable and integrated aqueous organic two-phase enzymatic hydrolysis. The system was consisted of propyl acetate and HAc-NaAc buffer (pH4.5) containing β-dextranase/epimedin A, and the hydrolysis was performed at 60 °C for 1 h. Consequently, epimedin A was completely hydrolyzed to sagittatoside A, and 95.02% of the product was transferred into the organic phase. Moreover, 90% of its initial activity was retained after seven cycles of hydrolysis. Additionally, the procedure was simpler than conventional enzymatic hydrolysis. Collectively, the newly proposed strategy is an efficient and promising approach for the preparation of sagittatoside A in industrial application.
