description: Este estudo pretende evidenciar as características específicas e originais da fábula enquanto género literário. Apresentamos a evolução do conceito referindo alguns dos períodos mais significativos da nossa cultura ocidental, o período clássico, a idade média e o renascimento. A reflexão de La Fontaine e o intenso debate posterior contribuíram para a emergência de uma consciência cultural comum. Apresentamos também uma análise e uma interpretação mitocrítica das características formais e ideológicas da fábula enquanto género alegórico. Referimos algumas das fábulas mais conhecidas e recorrentes em Portugal, as suas morais e as conotações culturais dos seus principais protagonistas. A investigação relaciona a fábula com outros géneros alegóricos e com a forma mais tradicional da cultura popular: o provérbio.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions.

Robustness of Majorana edge modes and topological order -- exact results for the symmetric interacting Kitaev chain with disorder

description: We investigate the robustness of Majorana edge modes under disorder and interactions. We exploit a recently found mapping of the interacting Kitaev chain in the symmetric region ($μ= 0$, $t = Δ$) to free fermions. Extending the exact solution to the disordered case allows us to calculate analytically the topological phase boundary for all interaction and disorder strengths, which has been thought to be only accessible numerically. We discover a regime in which moderate disorder in the interaction matrix elements enhances topological order well into the strongly interacting regime $U > t$. We also derive the explicit form of the many-body Majorana edge wave function revealing how it is dressed by many-particle fluctuations from interactions. The qualitative features of our analytical results are valid beyond the fine-tuned integrable point as expected from the robustness of topological order and as corroborated here by an exact diagonalization study of small systems.

description: The $DD^{*}$ potentials are studied within the framework of heavy meson chiral effective field theory. We obtain the effective potentials of the $DD^{*}$ system up to $O(ε^2)$ at the one-loop level. In addition to the one-pion exchange contribution, the contact and two-pion exchange interactions are also investigated in detail. Furthermore, we search for the possible molecular states by solving the Schrödinger equation with the potentials. We notice that the contact and two-pion exchange potentials are numerically non-negligible and important for the existence of a bound state. In our results, no bound state is found in the $I=1$ channel within a wide range of cutoff parameter, while there exists a bound state in the $I=0$ channel as the cutoff is near $m_ρ$ in our approach.

On the sign patterns of entrywise positivity preservers in fixed dimension

description: Given $I\subset\mathbb{C}$ and an integer $N>0$, a function $f:I\to\mathbb{C}$ is entrywise positivity preserving on positive semidefinite (p.s.d.) matrices $A=(a_{jk})\in I^{N\times N}$, if the entrywise application $f[A]=(f(a_{jk}))$ of $f$ to $A$ is p.s.d. for all such $A$. Such preservers in all dimensions have been classified by Schoenberg and Rudin as being absolutely monotonic [Duke Math. J. 1942, 1959]. In fixed dimension $N$, results akin to work of Horn and Loewner [Trans. AMS 1969] show the first $N$ nonzero Maclaurin coefficients of a positivity preserver $f$ are positive; and the last $N$ coefficients are also positive if $I$ is unbounded. However, little was known about the other coefficients: the only examples to date for unbounded domains $I$ were absolutely monotonic, so work in all dimensions; and for bounded $I$ examples of non-absolutely monotonic preservers were very few (and recent). In this paper, we completely characterize the sign patterns of the Maclaurin coefficients of positivity preservers in fixed dimension $N$, over bounded and unbounded domains $I$. In particular, the above Horn-type conditions cannot be improved upon. This also yields the first polynomials which preserve positivity on p.s.d. matrices in $I^{N\times N}$ but not in $I^{(N+1)\times (N+1)}$. We obtain analogous results for real exponents using the Harish-Chandra-Itzykson-Zuber formula. We then go from qualitative bounds, which suffice to understand all possible sign patterns, to exact quantitative bounds. As an application, we extend our previous qualitative and quantitative results to understand preservers of total non-negativity in fixed dimension - including their sign patterns. We deduce several further applications, including extending a Schur polynomial conjecture by Cuttler-Greene-Skandera to obtain a novel characterization of weak majorization for real tuples.

Enhancement of Concrete Composite Decks

description: Reinforced concrete construction and steel construction are two of the most common contemporary construction methods. Both methods make use of composite decks as floor systems and diaphragms. During the design of composite decks, the steel deck is typically disregarded when calculating the strength of the slab since shear transfer can’t be ensured. This essentially results in efficient use of material. This report presents a method for ensuring shear transfer through the use of typical sheet metal screws, driven through the corrugated steel deck and embedded in the concrete. Both experimental and analytical work support an increase in strength with the addition of embedded fasteners, and an increase in strength with the addition of synthetic reinforcing fibers.

description: A combined experimental and theoretical study of a newly synthesized cycloadduct of spirooxindole based thiochromene scaffold via [3 + 2] cycloaddition (32CA) reaction approach has been performed. The final adducts occurred via reaction of azomethine ylide (AY) with the ethylene derivative via ortho/endo 32CA protocol in respective regio- and diastereoselective fashion. In the light of the importance of intermolecular interactions in the crystal stability, Hirshfeld calculations were employed to predict all possible contacts affecting the molecular packing in the solid state of the studied systems. The results shed the light on the importance of O…H, F…H and H…C interactions as well as the π-π stacking interactions on the molecular packing. DFT calculations were used to compute the minimum energy structures and predict their electronic properties such as dipole moment, charge population and conceptual DFT reactivity descriptors. The 1H- and 13C-NMR spectra of the studied systems were calculated and the resulting chemical shifts correlated very well with the experimental data (R2= 0.991-0.978). The anti-cancer activity of the synthesized spirooxindole based thiochromene motif was assessed and showed IC50 of 8.34 ± 0.64, 11.25 ± 0.28, 16.0 ± 0.7, and 25.3 ± 0.25 µM against the four cancer cell lines MCF-7, MDA-MB231, PC3, and HeLa, respectively.

description: The predictions of Moore's law are considered by experts to be valid until 2020 giving rise to "post-Moore's" technologies afterwards. Energy efficiency is one of the major challenges in high-performance computing that should be answered. Superconductor digital technology is a promising post-Moore's alternative for the development of supercomputers. In this paper, we consider operation principles of an energy-efficient superconductor logic and memory circuits with a short retrospective review of their evolution. We analyze their shortcomings in respect to computer circuits design. Possible ways of further research are outlined.

description: The spectroscopic, solvent effects, reactivity and MD simulations of N'-[(1E)-(2,6-dichlorophenyl-methylidene]adamantane-1-carbohydrazide (DMC) are reported. Solvation free energies of DMC in chloroform, ethanol and acetonitrile are −21.96, −24.39 and −12.31 kcal/mol and ethanol may be better for the solubilization. Electron donating and electron accepting powers are somewhat lower in solution, revealing a certain increase in the tendency to receiving electrons and a decrease in donate electrons in solution, except in acetonitrile, in which showed slightly higher values then in vacuum. ALIE surface show that regions where low energy is required to remove electrons are on benzene ring, chlorine atoms and N5. DMC is forming good contacts with protein's binding site residues and is important in the complex's stability showing antiviral activity.

description: The works of Hassett and Kuznetsov identify countably many divisors $C_d$ in the open subset of $\mathbb{P}^{55}=\mathbb{P}(H^0(\mathcal{O}_{\mathbb{P}^5}(3)))$ parametrizing all cubic 4-folds and conjecture that the cubics corresponding to these divisors are precisely the rational ones. Rationality has been known classically for the first family $C_{14}$. We use congruences of 5-secant conics to prove rationality for the first three of the families $C_d$, corresponding to $d=14, 26, 38$ in Hassett's notation.

An application of the Palladium catalyzed Suzuki reaction on amine-(CH2)3-PEG3-(CH2)3-amine linked 6-bromo imidazo[1,2-a]pyridine-2-carboxamide was reported and their products are discussed. The reaction was optimized through numerous catalytic conditions for this strategy, and it was fixed with the best approach having advantages of less reaction time, higher degree of yield, most consumption of starting material, and selection of best catalyst for the success of the reaction. The ideal spectroscopic characterization (PMR, CMR, IR and MS) have been utilized for the finalization of the synthesized adducts.

description: Objectives: To assess the determinants of Patient’s Global Assessment of Disease Activity (PtGA) and Physician’s Global Assessment of Disease Activity (PhGA) in overall and Japanese patients with rheumatoid arthritis (RA) from two large randomized controlled trials. Methods:Post hoc analysis of overall and Japanese RA patients who had previous inadequate responses to methotrexate or who had no/minimal previous disease-modifying antirheumatic drug treatment. We examined correlations between PtGA/PhGA and tender joint count in 28 joints (TJC28), swollen joint count in 28 joints (SJC28), inflammatory markers, pain visual analog scale (VAS), and other patient-reported outcomes at baseline, Week 12, and Week 24. Determinants of PtGA/PhGA were identified. Results: In overall populations, pain VAS was the main determinant of PtGA, whereas TJC28 was the main determinant of PhGA in both studies. In Japanese populations, consistent with overall populations, pain VAS was the main determinant of PtGA in both studies; in contrast to overall populations, pain VAS and SJC28/TJC28 played an important role in PhGA. Conclusion: Pain was the most important determinant of PtGA, whereas determinants of PhGA varied between populations/studies and were mostly explained by pain/joint counts. Physicians should be aware of patients’ perceptions of disease activity when performing assessments/prescribing treatments.

description: A simple and effective approach has been established for the synthesis of a new series of 1,4-dihydropyridin-3,5-dicarbonitriles, hexahydroacridine-1,8-diones, 7,14-dihydro-6H,8H-dichromeno[4,3-b:3′,4′-e]pyridine-6,8-diones, and 1,4,7,8-tetrahydrodipyrazolo[3,4-b:4′,3′-e]pyridines which are linked to phenoxy-N-arylacetamide. The novel products were obtained through the Hantzsch reaction of various 2-(4-formylphenoxy)-N-arylacetamides with the respective 3-aminocrotononitrile or a mixture of 1,3-dicarbonyl compounds and ammonium acetate. Elemental and spectral data were used to confirm the structures of the newly synthesized compounds. The desired products could not be made by alkylation of the suitable phenol derivatives with 2-chloro-N-phenylacetamide.

description: A carbamate-linked-bistriazole (5) was prepared by click reaction of diethynyl 1,3-phenylenedicarbamate (2) and phenyl azide derivative (4) in DMF/H2O using copper sulfate and sodium ascorbate as a catalyst at room temperature for fluoride ion sensing. The structural analysis of synthesized compound was done by using 1HNMR, 13C NMR, FTIR and HRMS. The sensing behavior of carbamate-linked-bistriazole (5) was examined by 1HNMR, UV–vis and fluorescence study. NMR titration study suggested the participation of triazole, amide and aromatic protons in binding of fluoride ion. UV–visible study established the 1:1 complexation ratio between sensor 5 and F– ion with stability constant K of 2.64 × 104 M−1 and detection limit in µM range (9.372 µM). Further, fluorescence titration for 5 (9.2 × 10−6 M) with fluoride ions exhibited an emission quenching at 424 nm along with small bathochromic shift. Density functional theory (DFT) calculations also confirmed interaction mechanism in 5a-F– complex established by, UV–visible, 1H NMR and fluorescence studies.

description: In this paper, we introduce a new theoretical framework built upon fractional Sobolev-type spaces involving Riemann-Liouville (RL) fractional integrals/derivatives, which is naturally arisen from exact representations of Chebyshev expansion coefficients, for optimal error estimates of Chebyshev approximations to functions with limited regularity. The essential pieces of the puzzle for the error analysis include (i) fractional integration by parts (under the weakest possible conditions), and (ii) generalised Gegenbauer functions of fractional degree (GGF-Fs): a new family of special functions with notable fractional calculus properties. Under this framework, we are able to estimate the optimal decay rate of Chebyshev expansion coefficients for a large class of functions with interior and endpoint singularities, which are deemed suboptimal or complicated to characterize in existing literature. We can then derive optimal error estimates for spectral expansions and the related Chebyshev interpolation and quadrature measured in various norms, and also improve the available results in usual Sobolev spaces of integer regularity exponentials in several senses. As a by-product, this study results in some analytically perspicuous formulas particularly on GGF-Fs, which are potentially useful in spectral algorithms. The idea and analysis techniques can be extended to general Jacobi spectral approximations.

description: Spectral analysis using overlapping sliding windows is among the most widely used techniques in analyzing non-stationary time series. Although sliding window analysis is convenient to implement, the resulting estimates are sensitive to the window length and overlap size. In addition, it undermines the dynamics of the time series as the estimate associated to each window uses only the data within. Finally, the overlap between consecutive windows hinders a precise statistical assessment. In this paper, we address these shortcomings by explicitly modeling the spectral dynamics through integrating the multitaper method with state-space models in a Bayesian estimation framework. The underlying states pertaining to the eigen-spectral quantities arising in multitaper analysis are estimated using instances of the Expectation-Maximization algorithm, and are used to construct spectrograms and their respective confidence intervals. We propose two spectral estimators that are robust to noise and are able to capture spectral dynamics at high spectrotemporal resolution. We provide theoretical analysis of the bias-variance trade-off, which establishes performance gains over the standard overlapping multitaper method. We apply our algorithms to synthetic data as well as real data from human EEG and electric network frequency recordings, the results of which validate our theoretical analysis.

description: During our continual searching programme for novel bioactive metabolites from Sarcophyton trocheliophorum, collected from Red Sea, we describe herein the isolation and structural elucidation of further two new pyrane-based cembranoid diterpenes: 9-hydroxy-7,8-dehydro-sarcotrocheliol (1) and 8,9-expoy-sarcotrocheliol acetate (2), along with the well-known sarcotrocheliol acetate (3), (+)-sarcophine (4), (+)-sarcophytoxide (5) and (-)-sarcophytoxide (6). The chemical structures of compounds 1 and 2 were determined on the basis of 1D and 2D NMR (1H, 13C, 1H–1H COSY, HMQC, HMBC and NOE), mass spectra (ESI and HR-ESIMS) and by comparison with related structures. The antimicrobial activities of the reported compounds 1–6 were investigated. According to the molecular docking study of compounds 1–6 using 3D structure of α,β tubulin in complex with taxol (PDB code 1JFF) and epothilone A (PDB code 1TVK), sarcophine (4) displayed the highest affinity towards both crystal structures, followed by 5 and 6, meanwhile pyrane-based cembranoid diterpenes (1–3) showed less affinity.

description: Catalytic use of benzene-1,3-disulfonic acid at an ordinary condition gets restricted due to its high hygroscopic and moisture sensitive nature. In the present study, a new catalytic material silica bonded bis(hydrogensulphato)benzene (SiO2-BHSB) was synthesized through a sequence of reactions, where the active catalytic part benzene-1,3-disulfonic acid was grafted on the surface of micro-sized silica by the chemical bonding. Structural features, purity, thermal stability, and acid strength of the synthesized SiO2-BHSB material were confirmed by the adequate analytical techniques such as FT-IR, solid-state CP-MAS 13C-NMR, CP-MAS 29Si-NMR, EDX, DTG, TGA, and volumetric studies. The synthesized material SiO2-BHSB was observed as an efficient and sustainable reaction promoter for a tandem reaction between 4-hydroxy-1-methyl-2(1H)-quinolone, malononitrile, and structurally diverse aldehydes to offer pyrano[3,2-c]quinolone scaffolds. An environmentally benign catalytic protocol in aqueous based solvent and at ordinary energy conditions was developed, wherein a tiny amount (3 mol%) of SiO2-BHSB was observed sufficient to catalyze the synthesis pyrano[3,2-c]quinolone scaffolds. Structures of the synthesized pyrano[3,2-c]quinolone derivatives were established from their physical and spectrometric data. Catalyst recovery and reuse study revealed that SiO2-BHSB sustains its catalytic activity even after five runs of its reuse. Use of aqueous-based solvent, environmentally compatible reaction conditions, ease of catalyst recovery and reuse are the additional salient features of the present protocol.

description: Commiphora wightii (Arn.) Bhandari, known as guggul, produces a medicinally important gum resin which is used extensively by Ayurvedic physicians to treat various ailments. However, most of the studies on C. wightii have been limited to its gum resin. Comprehensive metabolic profiling of leaves, stem and gum resin samples was undertaken to analyse aqueous and non-aqueous metabolites from three distinct chemotypes (NBRI-101, NBRI-102 and NBRI-103) shortlisted from different agro-climatic zones. GC-MS, HPLC and NMR spectroscopy were used for comprehensive metabolomics. Multivariate analysis showed characteristic variation in quinic and citric acids, myo-inositol and glycine (aqueous metabolites) and 2,6-di-tert-butyl-phenol, trans-farnesol and guggulsterones (non-aqueous metabolites) amongst the three chemotypes. Quinic acid, citric acid and myo-ionositol were detected in substantial quantities from leaves and stem samples which provide opportunities for novel nutraceutical and pharmaceutical formulations. Quinic acid, from the leaves, was identified as a marker metabolite for early selection of high guggulsterones-yielding cultivars.

description: Due to desirable properties of filamentous silica nanoparticles (KCC-1), these compounds can be considered as appropriate support for the preparation of heterogeneous catalysts. In this study, immobilized CdCl2 on modified KCC-1 surfaces was fruitfully prepared. The structure of prepared catalyst was confirmed by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM), transmission electron microscope (TEM), brunauer-emmett-teller (BET) and energy dispersive X-Ray (EDX) analysis. The efficiency of obtained solid acid catalyst was studied for the synthesis of some amidoalkyl naphthole and amidoalkyl naphthoquinones through a multicomponent reaction in solvent free conditions. The structure of all obtained products was characterized by analytical and spectroscopic methods.

description: Here we consider some well-known facts in syntax from a physics perspective, allowing us to establish equivalences between both fields with many consequences. Mainly, we observe that the operation MERGE, put forward by N. Chomsky in 1995, can be interpreted as a physical information coarse-graining. Thus, MERGE in linguistics entails information renormalization in physics, according to different time scales. We make this point mathematically formal in terms of language models. In this setting, MERGE amounts to a probability tensor implementing a coarse-graining, akin to a probabilistic context-free grammar. The probability vectors of meaningful sentences are given by stochastic tensor networks (TN) built from diagonal tensors and which are mostly loop-free, such as Tree Tensor Networks and Matrix Product States, thus being computationally very efficient to manipulate. We show that this implies the polynomially-decaying (long-range) correlations experimentally observed in language, and also provides arguments in favour of certain types of neural networks for language processing. Moreover, we show how to obtain such language models from quantum states that can be efficiently prepared on a quantum computer, and use this to find bounds on the perplexity of the probability distribution of words in a sentence. Implications of our results are discussed across several ambits.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.
