description: Children with cerebral palsy (CP) are faced with long-term dysfunction. The International Classification of Functioning, Disability and Health for Children and Youth (ICF-CY) has been proposed but the complicated procedure limits the feasibility of clinical application and the exploration of health degrees. This study was aimed to establish a Mokken scale based on the ICF-CY for CP, and then to estimate psychometric properties through the derived Rasch model. 150 children with CP were assessed by the categories of “b” and “d” components in the core set. The binarized data was screened by the Mokken scale analysis and utilized for generating a reliable Rasch model. The validity of the final model was checked by the correlation between person ability, Gross Motor Function Classification System (GMFCS) and total scores. Using the Mokken scale to guide Rasch modeling, we can parameterize the properties of ICF-CY and realize the simple assessment of person abilities for children with CP.
Generalizing the Heisenberg uncertainty relation

description: The proof of the Heisenberg uncertainty relation is modified to produce two improvements: (a) the resulting inequality is stronger because it includes the covariance between the two observables, and (b) the proof lifts certain restrictions on the state to which the relation is applied, increasing its generality. The restrictions necessary for the standard inequality to apply are not widely known, and they are discussed in detail. The classical analog of the Heisenberg relation is also derived, and the two are compared. Finally, the modified relation is used to address the apparent paradox that eigenfunctions of the z component of angular momentum L_z do not satisfy the ϕ-L_z Heisenberg relation; the resolution is that the restrictions mentioned above make the usual inequality inapplicable to these states. The modified relation does apply, however, and it is shown to be consistent with explicit calculations.

2D Weyl Fermi gas model of Superconductivity in the Surface state of a Topological Insulator at High Magnetic fields

description: The Nambu-Gorkov Green's function approach is applied to strongly type-II superconductivity in a 2D spin-momentum locked (Weyl) Fermi gas model at high perpendicular magnetic fields. When the chemical potential is sufficiently close to the branching (Dirac) point, such that the cyclotron effective mass, $m^{\ast }$, is a very small fraction of the free electron mass, $m_{e}$, relatively large portion of the $H-T$ phase diagram is exposed to magneto-quantum oscillation effects. This model system is realized in the 2D superconducting state, observed recently on the surface of the topological insulator Sb$_{2}$Te$_{3} $, for which high field measurements were reported at low carrier densities with $m^{\ast}=0.065m_{e}$. Calculations of the pairing condensation energy in such a system, as a function of $H$ and $T$, using both the Weyl model and a reference standard model, that exploits a simple quadratic dispersion law, are found to yield indistinguishable results in comparison with the experimental data. Significant deviations from the predictions of the standard model are found only for very small carrier densities, when the cyclotron energy becomes very large, the Landau level filling factors are smaller than unity, and the Fermi energy shrinks below the cutoff energy.

The Luminosity and Angular Distributions of Long GRBs

description: The realization that the total energy of GRBs is correlated with their jet break angles motivates the search for a similar relation between the peak luminosity, $L$, and the jet break angles, $L\proptoθ^{-2}$. Such a relation implies that the GRB luminosity function determines the angular distribution. We re-derive the GRB luminosity function using the BATSE peak flux distribution and compare the predicted distribution with the observed redshift distribution. The luminosity function can be approximated by a broken power law with a break peak luminosity of $4.4 \times 10^{51}$ erg/sec, a typical jet angle of 0.12 rad and a local GRB rate of $0.44 h_{65}^{3}$ Gpc$^{-3}$yr$^{-1}$. The angular distribution implied by $L\proptoθ^{-2}$ agrees well with the observed one, and implies a correction factor to the local rate due to beaming of $75\pm25$ (instead of 500 as commonly used). The inferred overall local GRB rate is $33\pm11 h_{65}^{3}$ Gpc$^{-3}$yr$^{-1}$. The luminosity function and angle distribution obtained within the universal structured jet model, where the angular distribution is essentially $\propto θ$ and hence the luminosity function must be $\propto L^{-2}$, deviate from the observations at low peak fluxes and, correspondingly, at large angles. The corresponding correction factor for the universal structure jet is $\sim 20 \pm 10$.

description: Analysis of an antimicrobial extract prepared from culture broth of the marine-derived actinomycete Streptomyces sp. G278 led to the isolation of ten compounds, 1-10. Two compounds, 2,5-Bis(5-tert-butyl-2-benzoxazolyl)thiophene (1), and 3-hydroxyl-2-methylpyridine (2) were isolated from a natural source for the first time. The structures of the isolated compounds were established by their spectral data analysis, including mass spectrometry, 1D-NMR, 2D-NMR, and X-ray crystallographic analysis in case of compound 3. All isolated compounds were evaluated for their antimicrobial activity against a panel of clinically significant microorganisms. Compounds 1 and 3 selectively inhibited Enterococcus faecalis (MIC: 256 μg/mL). Compound 2 was found to have antibacterial and antifungal activity against Escherichia coli (MIC: 64 μg/mL), Salmonella enterica (MIC: 256 μg/mL), Staphylococcus aureus (MIC: 256 μg/mL), Enterococcus faecalis (MIC: 256 μg/mL), and Candida albicans (MIC: 64 μg/mL). Except for compounds 9 and 10, the other known metabolites (4-8) also exhibited antimicrobial activity.

description: Spiking neural networks (SNNs) enable power-efficient implementations due to their sparse, spike-based coding scheme. This paper develops a bio-inspired SNN that uses unsupervised learning to extract discriminative features from speech signals, which can subsequently be used in a classifier. The architecture consists of a spiking convolutional/pooling layer followed by a fully connected spiking layer for feature discovery. The convolutional layer of leaky, integrate-and-fire (LIF) neurons represents primary acoustic features. The fully connected layer is equipped with a probabilistic spike-timing-dependent plasticity learning rule. This layer represents the discriminative features through probabilistic, LIF neurons. To assess the discriminative power of the learned features, they are used in a hidden Markov model (HMM) for spoken digit recognition. The experimental results show performance above 96% that compares favorably with popular statistical feature extraction methods. Our results provide a novel demonstration of unsupervised feature acquisition in an SNN.

All compounds were isolated for the first time from the Spiraea genus. Furthermore, the isolated compounds were subjected to assay inhibitory activity on pro-inflammatory cytokine interleukin-6 production in lipopolysaccharide-stimulated RAW 264.7 cells and all the compounds showed anti-inflammatory effects.

description: We estimate energy spectra and fluxes at the Earth's surface of the cosmic and Galactic neutrino backgrounds produced by thermonuclear reactions in stars. The extra-galactic component is obtained by combining the most recent estimates of the cosmic star formation history and the stellar initial mass function with accurate theoretical predictions of the neutrino yields all over the thermonuclear lifetime of stars of different masses. Models of the structure and evolution of the Milky Way are used to derive maps of the expected flux generated by Galactic sources as a function of sky direction. The predicted neutrino backgrounds depend only slightly on model parameters. In the relevant 50 keV-10 MeV window, the total flux of cosmic neutrinos ranges between 20 and 65 particles per square cm per s. Neutrinos reaching the Earth today have been typically emitted at redshift z~2. Their energy spectrum peaks at E~0.1-0.3 MeV. The energy and entropy densities of the cosmic background are negligible with respect to the thermal contribution of relic neutrinos originated in the early universe. In every sky direction, the cosmic background is outnumbered by the Galactic one, whose integrated flux amounts to 300-1000 particles per square cm per s. The emission from stars in the Galactic disk contributes more than 95 per cent of the signal.

description: We propose an experiment, where the Bell inequality is violated in a many-body system of massive particles. The source of correlated atoms is a spinor $F=1$ Bose-Einstein condensate residing in an optical lattice. We characterize the complete experimental procedure--- the local operations, the measurements and the inequality---necessary to run the Bell test. We show how the degree of violation of the Bell inequality depends on the strengths of the two-body correlations and on the number of scattered pairs. We show that the system can be used to demonstrate the Einstein-Podolsky-Rosen paradox. Also, the scattered pairs are an excellent many-body resource for the quantum-enhanced metrology. With the possibility to generalize our analysis to other configurations in a straightforward way, the presented inquiry can be important in the planning of the forthcoming Bell tests in correlated atomic systems.

description: We consider the nuclear spin-lattice relaxation rate, $1/T_1T$ in superconductors with accidental nodes. We show that a Hebel-Slichter-like peak occurs even in the absence of an isotropic component of the superconducting gap. The logarithmic divergence found in clean, non-interacting models is controlled by both disorder and electron-electron interactions. However, for reasonable parameters, neither of these effects removes the peak altogether.

description: Experimentally measured mechanical properties of hollow sphere steel foam are the subject of this paper. The characterization of the hollow sphere foam encompasses compressive yield stress and densification strain, compressive plastic Poisson’s ratio, and compressive unloading modulus, as well as tensile elastic modulus, tensile unloading modulus, tensile yield stress, and tensile fracture strain. Shear properties are also included. These tests provide sufficient information to allow calibration of a macroscopic, continuum constitutive model. Calibrated foam plasticity parameters are tabulated, and unique feature of foam plasticity are explained. Also, initial development of mesoscale simulations, which explicitly model voids and sintered hollow spheres, is reported. This work is part of a larger effort to help the development of steel foam as a material with relevance to civil engineering applications.

description: L’articolo analizza e interpreta il paratesto di Gioventù cannibale come strumento di costruzione di un caso editoriale e come punto di partenza per una revisione critica dell’opera, intesa come esempio emblematico di tardo-postmodernismo italiano. Si introducono dapprima riferimenti e premesse culturali dei cannibali italiani, quali il pulp nordamericano, l’avant-pop e il rigetto (ormai quasi un riflesso inconscio) di una distinzione estetica fra letteratura ‘alta’ e ‘bassa’. Dopo una breve disamina delle connotazioni specifiche del titolo e della quarta di copertina (non priva, quest’ultima, di suggestioni moralistico-religiose, tratto tipico del postmodernismo italiano secondo Remo Ceserani), si evidenziano criticamente i modelli di una presunta estetica e filosofia cannibale, introdotti nella prefazione di Daniele Brolli del 1996. Una presenza (la postfazione di Emanuele Trevi) e un’assenza (le brevi biografie degli autori), rilevate nel confronto fra prima e seconda edizione, consentono di accertare lo stato post-mortem dei cannibali all’altezza del 2006, ormai promessa mancata della letteratura italiana di inizio millennio. Si analizzano infine esempi emblematici ed effetti di intertestualità nel paratesto del racconto Il mondo dell’amore di Aldo Nove, che offre spunti di riflessione sul rapporto, parodico e serio al tempo stesso, fra avanguardie novecentesche e linguaggio cannibale.

description: The synthesis of laser-induced graphene (LIG) from polyimide (PI) sheets provides a cost-effective and direct patterning approach for graphene-based electronic devices. However, the fabrication of LIG-based electrodes toward photovoltaic applications urgently needs to be explored. Herein, facile high-yield production of the porous LIG counter electrodes for DSSC applications was demonstrated by laser induction of PI film. The electrical conductivity and electrocatalytic activity of the LIG electrodes increased with the applied laser power due to the formation of a unique hierarchical porous graphene structure with abundant edges and defects, which resulted in an evident improvement in power conversion efficiency (PCE) of 3.56%. In addition, a one-step in situ synthesis of Pt/LIG composite was further demonstrated by laser irradiation on the PI sheet with low loadings of Pt precursor to obtain a Pt-less counter electrode. It is found that the Pt/LIG composite electrode-based DSSC achieved a higher PCE of 3.80%, which is comparable to that of pure Pt-based DSSC. This study demonstrates that the porous LIG from PI films is a promising candidate as a carbonaceous counter electrode for DSSCs.

description: Madonna Fiammetta, protagonista dell’Elegia (omodiegetica) da Boccaccio a lei intitolata, annuncia nel prologo di voler «narrare i casi» suoi. Si tratta in realtà, dopo aver rintracciato in due capitoli la brevissima storia d’amore-passione da lei vissuta con l’amante che l’ha sedotta e poi lasciata, di renderci partecipi dell’altalena degli stati passionali che fa seguito all’abbandono da parte del traditore, il quale non dà più nessuna notizia, nonostante la promessa del ritorno. L’andamento ciclico degli affetti, interrotto solo da tentativi sia di cura (proposta dai familiari), sia di suicidio dell’eroina, tutti però fallimentari, costituisce una sorta di anti-narrazione, se il concetto di narrazione implica dispiegamento su un asse di successione temporale di eventi diretti a un(a) fine. Il saggio, dopo aver analizzato la temporalità paradossale del dire elegiaco, si interroga quindi su quel che narrazione può significare in simile contesto.

Separable states are more disordered globally than locally

description: A remarkable feature of quantum entanglement is that an entangled state of two parties, Alice (A) and Bob (B), may be more disordered locally than globally. That is, S(A) > S(A,B), where S(.) is the von Neumann entropy. It is known that satisfaction of this inequality implies that a state is non-separable. In this paper we prove the stronger result that for separable states the vector of eigenvalues of the density matrix of system AB is majorized by the vector of eigenvalues of the density matrix of system A alone. This gives a strong sense in which a separable state is more disordered globally than locally and a new necessary condition for separability of bipartite states in arbitrary dimensions. We also investigate the extent to which these conditions are sufficient to characterize separability, exhibiting examples that show separability cannot be characterized solely in terms of the local and global spectra of a state. We apply our conditions to give a simple proof that non-separable states exist sufficiently close to the completely mixed state of $n$ qudits.

description: Recently discovered Dirac and Weyl semimetals display unusual magnetoresistance phenomena, including a large, non-saturating, linear transverse magnetoresistance and a negative longitudinal magnetoresistance. The latter is often considered as evidence of fermions having a defined chirality. Classical mechanisms, due to disorder or non-uniform current injection, can however, also produce negative longitudinal magnetoresistance. Here, we report on magnetotransport measurements performed on epitaxial thin films of Cd3As2, a three-dimensional Dirac semimetal. Quasi-linear positive transverse magnetoresistance and negative longitudinal magnetoresistance are observed. By evaluating films of different thickness and by correlating the temperature dependence of the carrier density and mobility with the magnetoresistance characteristics, we demonstrate that both the quasi-linear positive and the negative magnetoresistance are caused by conductivity fluctuations. Chiral anomaly is not needed to explain the observed features.

description: Pubblicata nel 1958, I racconti di Italo Calvino è una raccolta contenente cinquantadue racconti – selezionati dall’autore stesso – fra cui alcuni già editi in volume e altri precedentemente apparsi solo su rivista o ancora inediti, ma che in seguito sarebbero confluiti in altre raccolte. Si tratta insomma di un’autoantologia, in cui Calvino lavora per dare un assetto coerente alla sua produzione breve tra 1945 e 1958. Rispetto a questo progetto antologico, l’architettura della raccolta svolge una funzione cruciale, a partire dalla suddivisione del materiale in sezioni fino ai titoli di queste ultime, tutti accomunati dalla presenza dell’aggettivo «difficile»: una scelta che ri-motiva i racconti antologizzati e orienta la loro lettura, oltre a legarsi all’immagine in copertina, che riproduce la Scena di battaglia dall’opera comica «Il Navigatore», di Paul Klee. Scopo del presente intervento è quello di indagare, a partire da questi aspetti, i dintorni del testo di Calvino (con Genette, i suoi paratesti) per mettere meglio a fuoco una tappa decisiva, ma forse ancora poco esplorata, del percorso letterario dell’autore.

description: The narrow K-z relation of powerful radio galaxies in the Hubble K diagram is often attributed to the stellar populations of massive elliptical galaxies. Extended over a large range of redshifts (0 4 implies that massive clouds were already formed at early epochs. We also find that the M_(bar,max) limit is similar to the critical mass M_crit of a self-gravitating cloud regulated by cooling (Rees & Ostriker, 1977; Silk, 1977). Moreover, the critical size r_crit = 75 Kpc is remarkably close to the typical diameter of Ly_alpha haloes surrounding distant radio galaxies. This confirms the validity of the method of baryonic mass determination based on the K-band luminosity. A puzzling question that remains to be answered is the short time-scale of mass-accumulation required to form such massive galaxies at z=4. We discuss the dispersion of the K-z relation and the link between the active nucleus and a large stellar mass.

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.

Il romanzo delle passioni in Italia nel «Tournant des Lumières»
Creators: name: Contarini, Silvia
Publisher: name: Griseldaonline
Year: 2019
Subjects: Tournant des Lumières; romanzo; Rousseau; passioni; idillio

description: Il saggio intende proporre un’analisi del romanzo epistolare italiano di fine Settecento attraverso l’esempio emblematico del libro incompiuto di Carlo Botta, Per questi dilettosi monti (1796), ritrovato e pubblicato per la prima volta da Luca Badini Confalonieri nel 1986. Specie se messo a confronto con altri esperimenti letterari coevi (come Il sepolcro su la montagna di Giambattista Giovio, 1796) che fanno riferimento a una medesima cornice ideologica di matrice rousseuiana, il romanzo di Botta si presenta come un originale tentativo di riprendere il discorso contraddittorio de La Nouvelle Héloïse riguardo al contrasto insanabile fra natura e civiltà, passione e ragione, anche se la sua forma incompiuta permette di formulare solo delle ipotesi sugli esiti di un intreccio narrativo costruito su una serie di prolessi e allusioni intertestuali. Da un punto di vista strutturale, tuttavia, sembra di poter affermare che il libro di Botta rappresenta una ulteriore conferma dell’evoluzione della forma epistolare in scrittura dell’io che contraddistingue il romanzo del Tournant des Lumières, anche in virtù della grande influenza del Werther di Goethe.

description: A new generation of surveys will soon map large fractions of sky to ever greater depths and their science goals can be enhanced by exploiting cross correlations between them. In this paper we study cross correlations between the lensing of the CMB and biased tracers of large-scale structure at high $z$. We motivate the need for more sophisticated bias models for modeling increasingly biased tracers at these redshifts and propose the use of perturbation theories, specifically Convolution Lagrangian Effective Field Theory ({\sc CLEFT}). Since such signals reside at large scales and redshifts, they can be well described by perturbative approaches. We compare our model with the current approach of using scale independent bias coupled with fitting functions for non-linear matter power spectra, showing that the latter will not be sufficient for upcoming surveys. We illustrate our ideas by estimating $σ_8$ from the auto- and cross-spectra of mock surveys, finding that {\sc CLEFT} returns accurate and unbiased results at high $z$. We discuss uncertainties due to the redshift distribution of the tracers, and several avenues for future development.

«Madre e maestra delle altre materie»: la filologia classica come scienza e metodo
Creators: name: Losacco, Margherita
Publisher: name: Griseldaonline
Year: 2019
Subjects: filologia classica; World philology; Karl Lachmann; storia della filologia classica; letteratura greca

description: L’articolo muove dalla prefazione di Giuseppe Billanovich alla traduzione italiana del celebre manuale Copisti e filologi, di L.R. Reynolds e N.G. Wilson. In essa, Billanovich scrive: «La filologia classica è una disciplina antica: madre e maestra delle altre materie nelle nostre Facoltà di lettere e filosofia». A partire da questa definizione, viene qui discusso il posto e il ruolo della filologia classica all’interno delle molteplici ‘filologie’; si fa cenno alle nuove frontiere della disciplina, aperta a ipotesi di ‘globalizzazione’ e sollecitata a ripensare i propri confini geografici e concettuali; si ripercorre brevemente la storia del metodo filologico, nato già in età alessandrina, praticato per tutta l’antichità (particolarmente istruttivo è il caso di Galeno), sistematizzato come scienza nel XIX secolo, e infine oggi esposto a nuove sfide e nuove sollecitazioni.

description: The composition of the essential oils (EOs) of O. vulgare L. EO and T. vulgaris EO, were analyzed by GC and GC–MS. Antifungal activities of the EOs and its main component, carvacrol, were evaluated against 27 clinical isolates of Malassezia furfur. Minimum inhibitory concentrations (MICs) were measured according to the broth microdilution protocols by Clinical and Laboratory Standards Institute (CLSI) modified for Malassezia spp. EOs and carvacrol showed low MIC values ranged 450–900 μg/ml against M. furfur. No differences in EOs antifungal activity were observed in sensitive to resistant fluconazole isolates. The antifungal activity obtained showed O. vulgare EO, T. vulgaris EO and carvacrol, their compound, as potential antimicrobial agents against M. furfur, yeast associated with human mycoses.

Automated Detection of Non-Relevant Posts on the Russian Imageboard "2ch": Importance of the Choice of Word Representations
Creators: name: Bakarov, Amir

Publisher: name: arXiv

Subjects: subject: Computation and Language (cs.CL)

description: This study considers the problem of automated detection of non-relevant posts on Web forums and discusses the approach of resolving this problem by approximation it with the task of detection of semantic relatedness between the given post and the opening post of the forum discussion thread. The approximated task could be resolved through learning the supervised classifier with a composed word embeddings of two posts. Considering that the success in this task could be quite sensitive to the choice of word representations, we propose a comparison of the performance of different word embedding models. We train 7 models (Word2Vec, Glove, Word2Vec-f, Wang2Vec, AdaGram, FastText, Swivel), evaluate embeddings produced by them on dataset of human judgements and compare their performance on the task of non-relevant posts detection. To make the comparison, we propose a dataset of semantic relatedness with posts from one of the most popular Russian Web forums, imageboard "2ch", which has challenging lexical and grammatical features.

description: The aim was to evaluate the susceptibility of blaESBL producing Enterobacteriaceae to Slovakian Thymus vulgaris essential oil (TVEO) alone and in combination with cefotaxime (CTX). TVEO composition was determined by gas chromatograph-mass spectrometer (GC/MS). Susceptibility to 21 antibiotics was determined by disc diffusion assay. Genes characterization for resistance to β-lactams was accomplished by polymerase chain reaction (PCR). The antibacterial activity was investigated by standard methods. The synergistic interaction was determined by checkerboard test. Thymol (34.5%), p-cymene (22.27%) and linalool (5.35%) were the major components present in the TVEO. The identified strains were multi-drug resistant (MDR). TVEO showed high activity against all MDR strains, including blaESBL producing isolates, with inhibition zones and MIC values in the range of 24–40 mm/10μL and 2.87–11.5 μg/mL, respectively. TVEO in combination with CTX showed a synergistic action against blaSHV-12 producing Escherichia coli (FICI 0.28) and an additive effect vs ESBL producing Enterobacter cloacae (FICI 0.987).
