description: We have analyzed a five-level $\wedge$-configuration Four-Wave Mixing (FWM) scheme for obtaining a high-efficiency FWM based on the two electromagnetically induced transparency. We find that the maximum FWM efficiency is nearly 30%, which is orders of magnitude larger than previous schemes based on the two electromagnetically induced transparency. Our scheme may provide a new possibility for technological applications such as nonlinear spectroscopy at very low light intensity, quantum single-photon nonlinear optics and quantum information science.

description: We analyse a narrow Feshbach resonance with ultra-cold chromium atoms colliding in d-wave. The resonance is made possible by dipole-dipole interactions, which couple an incoming $l=2$ collision channel with a bound molecular state with $l=0$. We find that three-body losses associated to this resonance increase with temperature, and that the loss feature width as a function of magnetic field also increases linearly with temperature. The analysis of our experimental data shows that the Feshbach coupling is small compared both to the temperature and to the density limited lifetime of the resonant bound molecular state. One consequence is that the three body losse rate is proportionnal to the square of the number of atoms, and that we can directly relate the amplitude of the losses to the Feshbach coupling parameter. We compare our measurement to a calculation of the coupling between the collisionnal channel and the molecular bound state by dipole-dipole interactions, and find a good agreement, with no adjustable parameter. An analysis of the loss lineshape is also performed, which enables to precisely measure the position of the resonance.

description: OpenEssayist is an automated writing evaluation system (AWE) designed to provide immediate textual and graphical feedback to students to help them improve their academic writing. One of the graphical visualisations as part of OpenEssayist, (named a ‘rainbow diagram’), illustrates how well the key concepts within the writing are connected. The rainbow diagram element has been subjected to research by Whitelock et al., (2014), who determined that participants could identify patterns across the diagrams, identifications which corresponded to essays awarded low-grade or high-grade marks by tutors. The research reported as part of this paper is a follow-on study, developed to determine how participants might use the rainbow diagram to improve academic writing. Thirteen (n=13) PhD students were interviewed face-to-face whilst an eye-tracker recorded their gaze on a rainbow diagram produced from an example of their own writing. The current work confirms that students can use rainbow diagrams to identify content that corresponds to high-grade and low-grade work in essay writing. Building on Whitelock’s research, the study also shows that the rainbow diagram can be used further, to enable students to understand coherence and structure within academic writing, and to facilitate reflection on what actions should be taken to improve their writing.

description: Based on the model of interaction between spherically symmetrical expanding matter and the external medium, we have estimated the parameters of the matter heated by the shock that was produced in the envelope ejected by the explosion of a classical nova during its interaction with the stellar wind from the optical companion. Using this model, we have shown that the matter ejected during the outburst in the system CI Cam had no steep velocity gradients and that the reverse shock could heat the ejected matter only to a temperature of ~0.1 keV. Therefore, this matter did not contribute to the mean temperature and luminosity of the system observed in the energy range 3-20 keV.

description: The workshop focused on recent advances in the analysis of lattice differential equations such as discrete Klein-Gordon and nonlinear Schrödinger equations as well as the Fermi-Pasta-Ulam lattice. Lattice differential equations play an important role in emergent directions of modern science. These equations are fascinating subjects for mathematicians because they exhibit phenomena, which are not encountered in classical partial differential equations, on one hand, but they may present toy problems for understanding more complicated Hamiltonian differential equations, on the other hand.
Proximity effect in atomic-scaled hybrid superconductor/ferromagnet structures: crucial role of electron spectra

description: We study the influence of the configuration of the majority and minority spin subbands of electron spectra on the properties of atomic-scaled superconductor-ferromagnet S-F-S and F-S-F hybrid structures. At low temperatures, the S/F/S junction is either a 0 or junction depending on the energy shift between S and F materials and the anisotropy of the Fermi surfaces. We found that the spin switch effect in F/S/F system can be reversed if the minority spin electron spectra in F metal is of the hole-like type.

description: We consider elastic single-particle scattering from a one-dimensional two-component trapped superfluid Fermi gas when the incoming projectile particle is identical to one of the confined species. Our theoretical treatment is based on the Hartree-Fock ground state of the trapped gas and a configuration-interaction description of the excitations. We determine the scattering phase shifts for the system and predict Fano-type scattering resonances that are a direct consequence of inter-atomic pairing. We describe the main characteristics of the scattering resonances and make a comparison with the results of BCS mean-field theory.

description: Malliavin calculus plays an important role in the stochastic analysis for Poisson point processes. This technique is tightly connected with chaotic expansions, that were introduced in the first half of the last century by Itˆo and Wiener. These techniques found an increasing number of applications, in particular in the field of stochastic geometry. This in turn inspired new research in stochastic analysis. Leading experts and young researchers of both fields met for a week for fruitful discussions and new cooperations.
Some aspects of the radiation chemistry of aqueous solutions of nitrous oxide
Creators: name: Head, David Alan
Publisher: name: University of British Columbia
Year: 2011

description: Deaerated acidic, neutral, and basic aqueous N₂0 solutions were irradiated with Co-60 γ -rays in order to: 1) determine the primary yields, and 2) resolve anomalies in relative rate constant ratios of the type k(e⁻aq +S)/k(e⁻aq +N₂0). The yields of the gaseous products N₂, 0₂, and H₂ were determined as a function of both pH and [N₂0]. About 10⁻² M N₂0 is commonly used to evaluate relative rate constant ratios, but this [N₂0] scavenges not only hydrated electrons (e⁻aq ) but also another species, X, (where G(X) = 0.65±0.1), resulting in erroneous rate constant ratios. Yields of primary species found were: Ge⁻aq = 2.4±0.1, G H₂O* ̴ 1.6, and G,H₂⁺, = 0.35±0.05. Kinetic competition studies of the reaction of N₂0 and H⁺ with e⁻aq were undertaken in the concentration ranges 3 x 10⁻⁵ to 2 x 10⁻⁴ M H⁺ and 10⁻⁴ to 10⁻³ M N₂O. The results cannot be explained by: 1) simple competition; 2) charge transfer, or 3) two species being scavenged. They may be explained by assuming a conversion of N₂O to another species in acid solution. This acid species, suggested to be H₂N₂O₂, is apparently five times less reactive toward e⁻aq than is N₂0 in neutral solution. Deaerated neutal N₂0 solutions were irradiated at extremely high intensity with very short pulses of 0.52 Mev electrons. The yields of the gaseous products N₂, O₂, and H₂ were studied in order to examine an expected decrease in solute products, and to determine primary yields at high dose rates. As predicted, significant scavenging occurs for high dose rates only at N₂0 concentrations an order of magnitude larger than those at low dose rates. Also the scavenging, which is complete at ~ 10⁻² M N₂O for low intensity irradiations, is not complete at 2.6 x 10⁻² M N₂0 for high intensity irradiations. These results indicate that the radiation yield of scavengable hydrated electrons is significantly larger at the high intensity used. The yield of hydrogen in pure water (G(H₂) = 1.15±0.2) can be explained on the basis of inter-spur reactions of e⁻aq, H, and OH.

Distopia etica e distopia biologica

description: Il contributo propone letture mirate di testi di Herbert G. Wells (The Time Machine, The Island of Doctor Moreau) e inoltre di testi novecenteschi quali Ape and Essence di Aldouls Huxley e Il pianeta irritabile di Paolo Volponi. Oggetto dello studio è il rapporto, significativo sotto il profilo della storia della letteratura fantastica, fra l’istanza biologica e scientifica e quella etica. Se in Wells il messaggio politico e sociale si arresta di fronte a insormontabili aporie e procede invece verso un’idea biologica dell’evoluzione umana (sulla scorta di Darwin e Thomas Huxley), la letteratura distopica novecentesca del dopo-bomba depaupera di curiosità effettive l’indagine scientifica e volge verso una riflessione etica che ha nuovamente il suo centro sull’uomo e sui suoi impegni nei confronti del futuro.

Subjects: subject: Konferenzschrift

description: Negative curves play a prominent role in the geometry of projective surfaces. They occur naturally as the irreducible components of exceptional loci of resolutions of surface singularities, at the same time, they are closely related to the geometry of the effective cone, and thus form an important building block of the Minimal Model Program. In the case of surfaces, classes of negative curves span extremal rays of the Mori cone. Any knowledge about them on a given surface reveals important information on linear series as well.
Improved kernel estimation of copulas: Weak convergence and goodness-of-fit testing

description: We reconsider the existing kernel estimators for a copula function, as proposed in Gijbels and Mielniczuk [Comm. Statist. Theory Methods 19 (1990) 445--464], Fermanian, Radulovič and Wegkamp [Bernoulli 10 (2004) 847--860] and Chen and Huang [Canad. J. Statist. 35 (2007) 265--282]. All of these estimators have as a drawback that they can suffer from a corner bias problem. A way to deal with this is to impose rather stringent conditions on the copula, outruling as such many classical families of copulas. In this paper, we propose improved estimators that take care of the typical corner bias problem. For Gijbels and Mielniczuk [Comm. Statist. Theory Methods 19 (1990) 445--464] and Chen and Huang [Canad. J. Statist. 35 (2007) 265--282], the improvement involves shrinking the bandwidth with an appropriate functional factor; for Fermanian, Radulovič and Wegkamp [Bernoulli 10 (2004) 847--860], this is done by using a transformation. The theoretical contribution of the paper is a weak convergence result for the three improved estimators under conditions that are met for most copula families. We also discuss the choice of bandwidth parameters, theoretically and practically, and illustrate the finite-sample behaviour of the estimators in a simulation study. The improved estimators are applied to goodness-of-fit testing for copulas.

Can TiO Explain Thermal Inversions in the Upper Atmospheres of Irradiated Giant Planets?

description: Spitzer Space Telescope infrared observations indicate that several transiting extrasolar giant planets have thermal inversions in their upper atmospheres. Above a relative minimum, the temperature appears to increase with altitude. Such an inversion probably requires a species at high altitude that absorbs a significant amount of incident optical/UV radiation. Some authors have suggested that the strong optical absorbers titanium oxide (TiO) and vanadium oxide (VO) could provide the needed additional opacity. However, if regions of the atmosphere are cold enough for Ti and V to be sequestered into solids they might rain out and be severely depleted. With a model of the vertical distribution of a refractory species in gaseous and condensed form, we address the question of whether enough TiO (or VO) could survive aloft in an irradiated planet's atmosphere to produce a thermal inversion. We find that, without significant macroscopic mixing, a heavy species such as TiO -- especially one that can condense in a cold-trap region -- cannot persist in a planet's upper atmosphere. In our model, the amount of macroscopic mixing that would be required to loft TiO to millibar pressures ranges from ~10^7 to ~10^{11} cm^2/s on HD 209458b, HD 149026b, TrES-4, OGLE-TR-56b, and WASP-12b, depending on the planet and on assumed condensate sizes. Such large values may be problematic for the TiO hypothesis. [Abridged]

Electron spin resonance studies of reaction intermediates in metallic halides
Creators: name: Catton, Richard Carl
Publisher: name: University of British Columbia
Year: 2011

description: The object of this work was to produce and identify reaction intermediates in systems containing group I and group II halides treated with fluorine. The systems which are studied in detail are the NaCl and KCl/F₂ and SrCl₂/F₂ systems. In accordance with predictions from kinetic studies, ESR has shown that treatment of vacuum-sublimed NaCl with F₂ at room temperature produces a defect containing an unpaired electron, and that the decay of this defect is retarded by Cl₂. The ESR spectrum indicates an anisotropic g-factor and unresolved hyperfine structure. In KCl, a spectrum is obtained which is closely similar except that the hyperfine structure is partly resolved. The spectra appear consistent with interactions of the unpaired electron with Cl atoms, rather than with F or such impurities as 0 or Br, and can be accounted for adequately by a model of the defect as linear Cl[formula omitted], i.e., an H center or something very similar. For NaCl, the spectra indicate that the vacuum-sublimed material is sometimes partly oriented. It is suggested that centers with one-electron deficiency are observable at such high temperatures in vacuum-sublimed material because this consists of essentially perfect crystals devoid of sites which could accept a second electron from the centers. The reaction of SrCL₂ powder or single crystal with fluorine at room temperature produces a defect, stable after removal of fluorine but located close to the reaction interface only, which has an electron spin resonance absorption. The ESR spectrum is consistent with a model of the defect as a chlorine atom displaced from an anion site towards a neighbouring anion vacancy. The principal directions of the hyperfine tensor and g-tensor are two two-fold axes and a four-fold axis of the SrCl₂ lattice. The tensor components indicate that the unpaired electron is localized on the Cl atom, and suggests that the atom is subject to a strong crystal field determind chiefly by two nearest-neighbour cations which define a two-fold axis of the crystal. The unpaired electron is in an orbital mainly of p-character and aligned along a two-fold axis which is probably the one perpendicular to the line of the cations. The single-crystal spectrum, although haying orientation-dependent line positions, has line shapes and intensities resembling those of a powder spectrum. This suggests a range of relative displacement of Cl atoms and neighbouring cations along a "reaction co-ordinate" which is probably a four-fold axis of the crystal.

We find that quenched randomness strongly suppresses transport, with the diffusion constant becoming reduced by several orders of magnitude upon the introduction of moderate disorder. We have also looked for but not found signs of a classical many-body localization transition at any nonzero strength of the spin-spin interactions.

Le distopiche geometrie di Utopia
Creators: name: Varotti, Carlo
Publisher: name: Griseldaonline
Year: 2021

description: L’articolo prende spunto da un racconto tratto da Mania (1997) di Daniele del Giudice, Fuga – ispirato a una delle più notevoli costruzioni dell’Illuminismo napoletano, il ‘Cimitero delle 366 fosse’ progettato dall’architetto Ferdinando Fuga. Il racconto è letto come un vero e proprio apologo filosofico, da interpretare alla luce di alcuni temi centrali della riflessione epistemologica di Daniele del Giudice (trattati soprattutto in Atlante occidentale). Il mito, strutturalmente moderno, di ‘Utopia’ fa da sfondo a questa riflessione, richiamato in uno dei suoi emblemi originari più macroscopici: la progettazione geometrica dello spazio cittadino come espressione di un ordine razionale che ‘organizza’ la dimensione morale e persino biologica della condizione umana. Il mito moderno della mappa e dell’atlante (simboli della progettualità scientista) trova nell’allegoria di Fuga, una sorta di rovesciamento parodico, suggerendo al lettore quell’aporia (vista da Horkheimer e Adorno, non meno che da A. Huxley) che è alla radice della Modernità occidentale: la consapevolezza che «l’utopia è necessaria», ma che nelle sue stesse illimitate potenzialità progettuali è contenuto, quasi di necessità, «il suo contrario, il suo fallimento».

Carte d’identità letterarie dei narratori decameroniani

description: Il saggio mira a ricostruire la storia interna dei novellatori decameroniani, le cui identità letterarie vengono per la prima volta alla luce con contorni nitidi. A partire da alcuni dati testuali è possibile infatti delineare con precisione le relazioni amorose e familiari che legano i personaggi del Decameron. Boccaccio fornisce al lettore soltanto alcuni elementi che sono però sufficienti per arrivare a tracciare i profili dei dieci novellatori. Particolare attenzione è rivolta all’Introduzione alla Prima giornata e alle ballate che concludono le diverse giornate, ma anche alle opere che precedono il Decameron e segnatamente Filocolo, Filostrato, Teseida, Comedia delle ninfe, Elegia di mf. Ricostruire la storia interna dei novellatori non consente soltanto di identificare un paradigma nuovo per leggere le novelle dal punto di vista di chi le racconta, ma anche di reinterpretare l’opera come punto di arrivo narrativo di tutta la precedente produzione di Boccaccio. Questo approccio dimostra ancora un volta quanto la storia portante dei dieci novellatori sia con ogni probabilità la più complessa invenzione narrativa del Certaldese.

description: Aiming for simplicity of explicit equations and at the same time controllable accuracy of the theory we present results for all thermodynamic quantities and correlation functions for the weakly interacting Bose gas at short-to-intermediate distances obtained within an improved version of Beliaev's diagrammatic technique. With a small symmetry breaking term Beliaev's diagrammatic technique becomes regular in the infrared limit. Up to higher-order terms (for which we present order-of-magnitude estimates), the partition function and entropy of the system formally correspond to those of a non-interacting bosonic (pseudo-)Hamiltonian with a temperature dependent Bogoliubov-type dispersion relation. Away from the fluctuation region, this approach provides the most accurate--in fact, the best possible within the Bogoliubov-type pseudo-Hamiltonian framework--description of the system with controlled accuracy. It produces accurate answers for the off-diagonal correlation functions up to distances where the behaviour of correlators is controlled by generic hydrodynamic relations, and thus can be accurately extrapolated to arbitrarily large scales. In the fluctuation region, the non-perturbative contributions are given by universal (for all weakly interacting U(1) systems) constants and scaling functions, which can be obtained separately--by simulating classical U(1) models--and then used to extend the description of the weakly interacting Bose gas to the fluctuation region. The theory works in all spatial dimensions and we explicitly check its validity against first-principle Monte Carlo simulations for various thermodynamic properties and the single-particle density matrix.

description: Hydroformylation of 5,6-anhydro-1,2-0-isopropylidene-α-D-glucofuranose (XXIV) with carbon monoxide (70 atm.) and hydrogen (70 atm.) at a temperature of 100-105° C. gave 6-deoxy-1,2-0-i sopropylidene-α-D-gluco-heptodialdo-1,4-furanose-3,7-pyranose (XXV) in 78% yield. Minor quantities of the rearrangement product, 6-deoxy-5-keto-1 ,2-0- i sopropyl i dene-α-D-gl ucofuranose (XXVI), and the hydro-hydroxymethyl at i on product, 6-deoxy-1 ,2-0- isopropyl idene-α-D-gl uco-hepto-1 , 4-furanose (XXVI I), were isolated in 9% and 4% yields, respectively. Acetylation of crude (XXV) afforded two anomeric derivatives (XXIX, XXVII I). Under identical experimental conditions, 5 ,6-dideoxy-1 , 2-0-isopropyl idene-α-D-xylo-hex-5-enofuranose (XXXIII) gave 5,6-dideoxy-α-D-xylo-heptodialdo-1 ,4-furanose-3,7-pyranose (XXXIV) in 51% yield. A minor amount of 5,6-dideoxy-α-D-xy1ohepto-1,4-furanose (XXXV) in about 5% yield was also detected by thin layer chromatography (T.L.C.) Fusion of 5 ,7-di-0-acetyl-6-deoxy-1,2-0-isopropylidene-α-D-gluco-heptodialdo-1,4-furanose-3,7-pyranose (XXVIII) with 5,6-dimethyl-benzimidazole using chloroacetic acid as a catalyst at 170-175°C. gave two anomeric nucleosides 1-(3'-0-acetyl-2'-deoxy-6’,7'-0-isopropylidene heptodialdo-4’,7'-pyrariose-α(and β-)-L-gulopyranosyl) -5,6-dimethyl -benzimidazole (XXXVII, XXXVIII) in 42% yield. These nucleosides were separated by multiple ascending development on preparative T.L.C. plates of silica gel G. impregnated with 2% G.E.Phosphor. Assignment of structures of the nucleosides was based on an analysis of their N.M.R. spectra.

description: We present a detailed study of GRB090111, focusing on its extra soft power-law photon index Gamma>5 at the very steep decay phase emission (power-law index alpha=5.1, steeper than 96% of GRBs detected by Swift) and the following peculiar X-ray re-brightening. Our spectral analysis supports the hypothesis of a comoving Band spectrum with the the peak of the nu*F_nu spectrum evolving with time to lower values: a period of higher temporal variability in the 1-2 keV light-curve ends when the E_peak evolves outside the energy band. The X-ray re-brightening shows extreme temporal properties when compared to a homogeneous sample of 82 early flares detected by Swift. While an internal origin cannot be excluded, we show these properties to be consistent with the energy injection in refreshed shocks produced by slow shells colliding with the fastest ones from behind, well after the internal shocks that are believed to give rise to the prompt emission have ceased.

description: It's hard to imagine that we can take a splinter and sharpen it down to the atomic level. It's even more impressive that we can bring this sharp tip close to a surface, scan it over the surface, and be sensitive to the tiny forces between the apex atom and individual atoms on the surface. Measuring and interpreting these forces is the goal of high-resolution atomic force microscopy (AFM). We perform frequency-modulation AFM (FM-AFM), in which we oscillate the tip and record the change in frequency as a measure of the interaction with the surface. FM-AFM performed in vacuum with stiff sensors has lead to amazing discoveries. Now, we are returning to the challenge of imaging samples in device- and biologically-relevant conditions. This contribution summarizes work that was performed in the Giessibl group to image with atomic resolution in ambient and liquid environments. We demonstrated atomic resolution with the qPlus sensor on KBr, and followed this with investigations on graphitic surfaces. We have also shown single-atomic defects and steps on the calcite surface.

Year: 2018

description: Face à proliferação, certamente compreensível, de tentativas, geralmente equivocadas e por diversos motivos nem sempre honestos, de apreciações, interpretações e explicações das (aparentes) coerências e (aparentes) incoerências manifestadas no decurso do pontificado do Papa Francisco, este artigo visa ser uma ajuda para se compreender uma parte substancial da rede espiritual fundamental que norteia tal pontificado. A saber: o discernimento inaciano. Nesse sentido, o texto abordará em pontos sucessivos: a importância do discernimento para os nossos dias; a definição de discernimento; a experiência fundacional de Inácio de Loyola; o significado da “consolação” e da “desolação” espiritual; a falsa consolação; a consolação sem causa precedente e, por fim, a eleição.

O Papa, o teólogo e o poeta: uma análise da linguagem poética e metafórica de Francisco à luz da filosofia da linguagem de Paul Ricœur
Creators: name: Xavier, Donizete José
Publisher: name: Humanística e Teologia
Year: 2018

description: Com o título “O Papa, o teólogo e o poeta”, este artigo pretende demonstrar que a linguagem utilizada pelo Papa Francisco está dotada de sentido teológico, o que atesta ao seu governo um posicionamento prático capaz de obter pela via argumentativa uma sistematização teórico-teológica. É próprio de Francisco tecer seus discursos e pronunciamentos com imagens e metáforas, o que permite conferir e elucidar o grau de profundidade de sua linguagem, de tal forma que a mesma o revela como um “Papa linguístico”. Se quisermos entender o fenômeno Francisco, a questão de sua linguagem é fundamental. Sendo assim, recorremos às nuances da filosofia da linguagem de Paul Ricœur para realizar uma análise da linguagem poética e metafórica de Francisco. Nesse sentido, objetiva-se demonstrar num primeiro plano que na linguagem do Sumo Pontífice há uma junção entre linguística e teologia que se opera pela mediação da linguagem destacando a sua capacidade criativa. Com um discurso poético, como o faz com maestria, Francisco traz à linguagem aspectos, qualidades, valores da realidade que, como afirma Ricœur, só podem ser ditos graças ao jogo complexo da enunciação metafórica e da transgressão regrada das significações usuais das nossas palavras. A linguagem de Francisco é rica em metáfora e em analogia pastoral. É linguagem cognitiva, afetiva, ética e testemunhal.

The striking endemism pattern of the species-richest snake genus At-ractus (Dipsadidae: Serpentes) highlights the hidden diversity in the Andes

description: The distribution of the highly diversified and species-rich snake genus Atractus was assessed in search for endemism areas. The dataset of 6,000 museum specimens was used to run an Endemicity Analyses in order to identify areas of biogeographic relevance for the genus Atractus. By using distinct methodological approaches and modifying the size and shape of grid cells we obtained a better adjustment to each species range, taking into account species distributed along the Andean and Atlantic Forest mountain ranges or certain vegetation constraints. Three scales of endemism were observed: micro endemic areas, represented by three different regions; intermediate sized endemic areas, represented by nine different regions; and macro-endemic areas, represented by four different provinces. Although most assessed regions corroborate well-defined biogeographic units according to the scientific literature, some, mainly located in the Colombian Andes, are not regularly considered in biogeographic syntheses carried out for vertebrates. Methodological approaches, along with a well curated database and taxonomic accuracy, may significantly influence the recovery of endemism areas, mainly considering mountain topography and local niche structure. The results present herein highlight the relevance of three Colombian Cordilleras, in order to completely understand Neotropical biota patterns of distribution. It is important to note that a well-resolved taxonomy represents both the framework and the first step toward a comprehensive biographical synthesis reducing Wallacean shortfalls in biodiversity.
Passioni boccacciane tra Francia e Italia
Creators: name: Fonio, Filippo
Publisher: name: Griseldaonline
Year: 2021

description: Il presente contributo è incentrato sulla ripresa della novella boccacciana, tanto sul piano della forma e del genere quanto su quello dei contenuti, da parte di La Fontaine e dell’abate Casti (di cui La Fontaine è un intertesto importante). Le riscritture di La Fontaine, e quelle in ottave di Casti, rappresentano al contempo un ripensamento del genere del racconto decameroniano, oltre che un tentativo di adeguamento a una lingua e/o a una temperie culturale e letteraria profondamente mutata rispetto a quella del modello. Tre casi studio sono analizzati nello specifico, al fine di mostrare in particolare come i due autori traspongano la metaforica e la lessematica delle passioni decameroniane, oltre a proporre dei modelli comportamentali profondamente innovanti rispetto a quelli dell’ipotesto.

Teologia moral e questões de género

description: A teologia tem um contributo a dar à temática das questões de género. Depois de observar como os caminhos das ciências humanas são meritórios mas inconclusivos em ordem a garantir a cada ser humano a sua instalação num modo sensato de viver, a teologia propõe um regresso à origem transcendental da subjetividade dos viventes, lugar onde se situam a fonte e o poder de viver. Esta teologia segue de perto a fenomenologia da vida de Michel Henry.

description: We show how the smooth geometry of Calabi-Yau manifolds emerges from the thermodynamic limit of the statistical mechanical model of crystal melting defined in our previous paper arXiv:0811.2801. In particular, the thermodynamic partition function of molten crystals is shown to be equal to the classical limit of the partition function of the topological string theory by relating the Ronkin function of the characteristic polynomial of the crystal melting model to the holomorphic 3-form on the corresponding Calabi-Yau manifold.

Publisher: name: Humanística e Teologia
Year: 2018

description: A partir da discussão de algumas teorias de género e do correspondente esclarecimento de alguns dos seus conceitos fundamentais, explora-se sobretudo a potencialidade relacional das diferenças inter-humanas, articuladas biológica, simbólica e socialmente. A partir desses fundamentos, propõe-se uma definição de família baseada no potencial relacional e institucional da sexualidade humana. É a partir dessa base antropológica que se pode elaborar uma leitura teológica deste tópico, na estreita conjugação entre interpretação natural e sobrenatural da relacionalidade humana.
