description: The in-plane correlation lengths and magnetic disorder of magnetic domains in a transition metal multilayer have been studied using neutron scattering techniques. A new theoretical framework is presented connecting the observed scattering to the in-plane correlation length and the dispersion of the local magnetization vector about the mean macroscopic direction. The results unambiguously show the highly correlated nature of the antiferromagnetically coupled domain structure vertically throughout the multilayer. We are easily able to relate the neutron determined magnetic dispersion and domain correlations to magnetization and magnetotransport experiments.

description: The atomization and mixing process of fuel under transverse jet is one of the important contents in the research of scramjet. In this paper, the atomization characteristics and penetration of kerosene under transverse jet are studied. The influences of pore size, quantity and arrangement, momentum flux ratio and the Mach number of the transverse flow were analyzed by using different optical measuring instruments. The results show that the pressure drop of fuel injection and the transverse jet velocity are all positively correlated with atomization characteristics, while the pore size is negatively correlated with atomization characteristics. By analyzing the penetration depth under different working conditions it can be seen that, when other factors are the same, the penetration depth increases with the increase of pore size and pressure drop. Through analysis the experimental data, the empirical formula of jet penetration about momentum flux ratio and axial distance are obtained.

description: Graph networks are a new machine learning (ML) paradigm that supports both relational reasoning and combinatorial generalization. Here, we develop universal MatErials Graph Network (MEGNet) models for accurate property prediction in both molecules and crystals. We demonstrate that the MEGNet models outperform prior ML models such as the SchNet in 11 out of 13 properties of the QM9 molecule data set. Similarly, we show that MEGNet models trained on $\sim 60,000$ crystals in the Materials Project substantially outperform prior ML models in the prediction of the formation energies, band gaps and elastic moduli of crystals, achieving better than DFT accuracy over a much larger data set. We present two new strategies to address data limitations common in materials science and chemistry. First, we demonstrate a physically-intuitive approach to unify four separate molecular MEGNet models for the internal energy at 0 K and room temperature, enthalpy and Gibbs free energy into a single free energy MEGNet model by incorporating the temperature, pressure and entropy as global state inputs. Second, we show that the learned element embeddings in MEGNet models encode periodic chemical trends and can be transfer-learned from a property model trained on a larger data set (formation energies) to improve property models with smaller amounts of data (band gaps and elastic moduli).

description: Exclusive processes at large momentum transfer Q factor into perturbatively calculable short-distance parts and long-distance hadronic wave functions. Usually, only contributions from the leading Fock states have to be included to leading order in 1/Q. We show that for exclusive decays of P-wave quarkonia the contribution from the next-higher Fock state |Q Qbar g> contributes at the same order in 1/Q. We investigate how the constituent gluon attaches to the hard process in order to form colour-singlet final-state hadrons and argue that a single additional long-distance factor is sufficient to parametrize the size of its contribution. Incorporating transverse degrees of freedom and Sudakov factors, our results are perturbatively stable in the sense that soft phase-space contributions are largely suppressed. Explicit calculations yield good agreement with data on chi_{c J} decays into pairs of pions, kaons, and etas. We also comment on J/psi decays into two pions.

description: We investigate linear and nonlinear evolution dynamics of light beams propagating along a dislocated edge-centered square lattice. The band structure and Brillouin zones of this novel lattice are analyzed analytically and numerically. Asymmetric Dirac cones as well as the corresponding Bloch modes of the lattice are obtained. By adopting the tight-binding approximation, we give an explanation of the asymmetry of Dirac cones. By utilizing the appropriate Bloch modes, linear and nonlinear asymmetric conical diffraction is demonstrated. We find that both the focusing and defocusing nonlinearities can enhance the asymmetry of the conical diffraction.

description: We present a detailed discussion of the crossover from mean-field to Ising critical behavior upon approach of the critical point, both for He3 and Xe. By combining different sets of experimental data, we are able to cover an unusually large temperature range on either side of the critical temperature T_c. Below T_c, we thus can make an accurate comparison with a recent calculation for the crossover of the coexistence curve. For the regime above T_c, an analysis of the compressibility demonstrates that the crossover regime in He3 is unexpectedly widened by a subtle interplay between quantum and critical fluctuations.

Our analysis shows that studying this process at the Tevatron Run II or the LHC can provide strong constraints on these models.

description: We present a study of the dependence of the mass-radius relation for DA white dwarf stars on the hydrogen envelope mass and the impact on the value of log g, and thus the determination of the stellar mass. We employ a set of full evolutionary carbon-oxygen core white dwarf sequences with white dwarf mass between 0.493 and 1.05 Msun. Computations of the pre-white dwarf evolution uncovers an intrinsic dependence of the maximum mass of the hydrogen envelope with stellar mass, i.e., it decreases when the total mass increases. We find that a reduction of the hydrogen envelope mass can lead to a reduction in the radius of the model of up to ~12%. This translates directly into an increase in log g for a fixed stellar mass, that can reach up to 0.11 dex, mainly overestimating the determinations of stellar mass from atmospheric parameters. Finally, we find a good agreement between the results from the theoretical mass-radius relation and observations from white dwarfs in binary systems. In particular, we find a thin hydrogen mass of MH ~ 2 10^-8 Msun, for 40 Eridani B, in agreement with previous determinations. For Sirius B, the spectroscopic mass is 4.3% lower than the dynamical mass. However, the values of mass and radius from gravitational redshift observations are compatible with the theoretical mass-radius relation for a thick hydrogen envelope of MH = 2 10^-6 Msun.

description: This article involves a qualitative study of climate change discourse by British Petroleum (BP) before and after the Deepwater Horizon oil spill in the Gulf of Mexico on April 20, 2010. The study aims at elucidating the impact of the spill upon BP’s climate change discourse by means of identifying conceptual metaphors in BP’s annual reports before and after the Deepwater Horizon spill. Data analysis reveals that BP’s climate change discourse prior to and following the Deepwater Horizon spill is framed by the metaphors Citizen and Journey. These findings are further discussed in the article.

description: For many years coherent states have been a useful tool for understanding fundamental questions in quantum mechanics. Recently, there has been work on developing a consistent way of including constraints into the phase space path integral that naturally arises in coherent state quantization. This new approach has many advantages over other approaches, including the lack of any Gribov problems, the independence of gauge fixing, and the ability to handle second-class constraints without any ambiguous determinants. In this paper, I use this new approach to study some examples of time reparameterization invariant systems, which are of special interest in the field of quantum gravity.

description: This thesis provides an in-depth discussion of recent Italian novels and movies engaging with different notions of ‘Southernness’ and ‘the south’ and/or exploring the predicament of contemporary southern Italy as a border-space. In considering this production this thesis aims at reframing and rethinking the concept of subjectivity and national identity in contemporary Italy. The aim is to highlight the importance of the interaction among multiple cultures, histories and elements of subjectivity (gender, ethnicity, sexuality) as co-constituting in the process of creation of national and regional identity and to illustrate the concomitant emergence of new conceptions of Italian cinema and Italian literature. This is achieved by drawing from the recent recasting of the ‘southern question’ in postcolonial terms, from renovated philosophical understandings of southern Italian identity and their points of contact with decolonial theories emerging from other souths, as well as from recent historical debates on the Italian diaspora and its links with Italian colonialism. In developing a framework for discussing texts on/from the south this thesis engages and contributes to contemporary debates on the work of southern writers informed by a postcolonial sensitivity, to discussions on the impact of the work of translingual authors writing in Italian and on translingual writing as self-translation, on Italian transcultural cinema. This research aims to answer how literary and cinematic representations sustain or run counter to the process of marginalization of the Italian South on one hand and of migrants to Italy on the other. It provides a discussion of the historical and cultural contexts to which many of the texts taken into consideration refer and proceeds to analyse in depth specific case studies. Novels by Giulio Angioni, Ornela Vorpsi and Evelina Santangelo and movies by Emanuele Crialese, Emma Dante and Jonas Carpignano are discussed in relation to the different and interrelated representations of ethnicity and culture, nationhood and mobility, gender and sexuality, ‘Italianness’ and ‘Southernness’ they provide. These analyses show how these texts, by exploring and establishing links among histories, cultures and languages of different souths participate to the ongoing transformation in transnational terms of Italian and southern Italian culture and identity.

description: Over the past decades, several computer codes were developed for simulation and analysis of thermal-hydraulics of system behaviors in nuclear reactors under operating, abnormal transient and accident conditions. However, simulation errors and uncertainties still inevitably exist even while these codes have been extensively assessed and used. In this work, a data-driven framework (Optimal Mesh/Model Information System, OMIS) is formulated and demonstrated to estimate simulation error and suggest optimal selection of coarse mesh size and models for low-fidelity system-level thermal-hydraulic simulation, such as coarse-mesh Computational Fluid Dynamics-like (CFD-like) codes, to achieve accuracy comparable to that of high-fidelity simulation, such as high-resolution CFD. Based on high-fidelity data and massive fast-running low-fidelity simulations, error database is built and used to train a machine learning model and find the relationship between local simulation error and local physical features. This machine learning model is then used to generate insight and help correct low-fidelity simulations for similar physical conditions. The OMIS framework is designed as a modularized six-step procedure and accomplished with methods and algorithms in the state of the art. A mixed convection case study was performed to illustrate the entire framework.

description: In Theoretical Morphology, an interest in the topic of stem allomorphy has been renewed the last two decades. On the other hand, the computational treatment of allomorphy is still a huge challenge since the first systematic attempts on predicting allomorphy with machine learning techniques. The goals of this paper are to predict the allomorphic changes and to show the essential contribution of various morphological, phonological and semantic characteristics. Therefore, we use a MaxEnt model to identify the weights of these characteristics that are directly dependent on allomorphy and help design a predictive model. Our model is based on AMIS and its overall accuracy was 86.49%. To improve the system, we tried a more rational approach to achieve a better performance (the correct prediction was raised to 91.43%).

Twenty-three Russian–Cypriot Greek (CG) simultaneous bilingual children took part in the study. Greek oral production data, obtained via elicited story-telling (Tsimpli et al. 2007), was recorded, transcribed and analysed in terms of object clitic (non)target production/omission and relevant features such as gender, case, number and person. The analysis of the data showed that the linguistic development of bilingual children is influenced by the quantity and quality of input and their linguistic environment as well as by their mothers’ linguistic profile and background.

description: Localizing a cloud of points from noisy measurements of a subset of pairwise distances has applications in various areas, such as sensor network localization and reconstruction of protein conformations from NMR measurements. In [1], Drineas et al. proposed a natural two-stage approach, named SVD-MDS, for this purpose. This approach consists of a low-rank matrix completion algorithm, named SVD-Reconstruct, to estimate random missing distances, and the classic multidimensional scaling (MDS) method to estimate the positions of nodes. In this paper, we present a detailed analysis for this method. More specifically, we first establish error bounds for Euclidean distance matrix (EDM) completion in both expectation and tail forms. Utilizing these results, we then derive the error bound for the recovered positions of nodes. In order to assess the performance of SVD-Reconstruct, we present the minimax lower bound of the zero-diagonal, symmetric, low-rank matrix completion problem by Fano's method. This result reveals that when the noise level is low, the SVD-Reconstruct approach for Euclidean distance matrix completion is suboptimal in the minimax sense; when the noise level is high, SVD-Reconstruct can achieve the optimal rate up to a constant factor.

description: We present the study of a sample of seven "bare" active galactic nuclei (AGN) observed with Suzaku. We interpret the spectrum of these sources with a relativistic reflection component and we employ our model RELXILL_NK to test the Kerr nature of their supermassive black holes. We constrain the Johannsen deformation parameters $α_{13}$ and $α_{22}$, in which the Kerr metric is recovered when $α_{13} = α_{22} = 0$. All our measurements are consistent with the hypothesis that the spacetime geometry around these supermassive objects is described by the Kerr solution. For some sources, we obtain quite strong constraints on $α_{13}$ and $α_{22}$ when compared to those found in our previous studies. We discuss the systematic uncertainties in our tests and the implications of our results.

Tambo, ca. 2000 m. Unspecified number of ♂ and ♀.
The MHNG collection contains some dissected parts in alcohol (MHNG-ARTO-18588). A label in the vial containing the parts has “ ♂ Gonop., Ant, Bein 2, ocb.” written on it, while the label in the jar is a photocopy of a label with “Diplopodes de la Colombie Pièces anatomoques (J. Carl 1914)” written on it, indicating that the specimen(s) from which the parts came were syntypes (it is possible that there are parts from more than one syntype in the tube). The whereabouts of the rest of the syntypes is unknown.

description: The precise theoretical characterization of a fractionalized phase in spatial dimensions higher than one is through the concept of ``topological order''. We describe a physical effect that is a robust and direct consequence of this hidden order that should enable a precise experimental characterization of fractionalized phases. In particular, we propose specific ``smoking-gun'' experiments to unambiguously settle the issue of electron fractionalization in the underdoped cuprates.

description: La investigación se realiza en la Facultad de Tecnología de la Salud de la Universidad de Ciencias Médicas Villa Clara; durante un período de siete meses. Se dirige a transformar el desarrollo de prácticas colaborativas estudiante- estudiante, en el proceso docente-educativo, en alumnos del primer año de la carrera Trabajo Social en Salud. La metodología empleada en este estudio fue cualitativa; logrando el acercamiento integral a las vivencias de estudiantes y docentes; desde las interpretaciones de su realidad. Se siguió un muestreo de tipo homogéneo. Para la recogida de información se empleo la observación participante y no participante, entrevistas semi-estructurada y en profundidad, revisión y análisis de documentos. Los resultados obtenidos muestran una tendencia hacia el desarrollo de prácticas colaborativas en el año. Se destacan como elementos que influyen en el fenómeno: la estabilización del trabajo en equipos -para el desarrollo de las actividades docentes- y la tutoría por parte de los profesores a los equipos -atendiendo no solo a los resultados sino también la forma en que se organizan para alcanzarlos.

Illustration only.
Carl (1914b: 859-860, figs 65-68, 70-71) provided a description of ♂ and ♀ and gave the locality “La Camelia, 1800 m, Kaffeepflanzung bei Angelopolis.” The MHNG collection contains four specimens in alcohol in two vials. The first vial (MHNG-ARTO-18467) contains two large specimens, one of them broken. The second vial (MHNG- ARTO-18468) contains two smaller specimens, one of them with a pin running the length of the body, a smaller vial with dissected parts and a label with “ Epinannolene fuhrmanni Carl ♀ ♂ (Schaltstadium)!” written on it. There are two further vials (MHNG-ARTO-18469 and MHNG- ARTO-18470) containing gonopods. The identification labels in the jar have “ Colombie ” and “ Colombie Coll. Fuhrmann ” written on them respectively, indicating that the specimens are syntypes. There are two ♀ syntypes (referred to as “Co-Typus” in the NMB catalogue) in the NMB (inventory number NMB-DIPL-00213a).

description: We show that the so-called permanent quantum Hall states are formed by the integer quantum Hall effects on the Haldane-Rezayi quantum Hall state. Novel conformal field theory description along with this picture is deduced. The odd denominator plateaux observed around $ν=5/2$ are the permanent states if the $ν=5/2$ plateau is the Haldane-Rezayi state. We point out that there is no such hierarchy on other candidate states for $ν=5/2$. We propose experiments to test our prediction.

description: Worldwide, the pressure on psychoanalysis to prove the results of its treatments according to the criteria of so-called evidence-based medicine has increased. While a large number of studies on the results of psychoanalytic short-term therapies are now available, such studies are still largely lacking on psychoanalysis and psychoanalytic long-term therapies. In a large multicentre study, the results of psychoanalytical and cognitive-behavioural longterm therapies in chronically depressed patients were compared, Both psychotherapies led to statistically highly significant changes in depressive symptoms three years after the start of the treatments However, the focus of psychoanalytic treatments is not exclusively on reducing psychopathological symptoms, but on changes in the inner world of the patients that are reminiscent of the goal of psychoanalyses that Freud has characterized as developing “the ability to love, work and enjoy life.” In the German-speaking community, such transformations are called “structural changes.” This article reports results on such structural changes achieved with the help of a sophisticated measuring instrument, the Operationalized Psychodynamic Diagnostics (OPD). These so-called structural changes are compared with symptomatic changes. Three years after the start of the treatments, significantly more patients in psychoanalytical treatments show such structural changes than patients in cognitive-behavioural treatments.

description: An axion background field induces tiny oscillating electric and magnetic fields in an external static magnetic field. This signature is used to search for axion dark matter. We use standard quantum field theory techniques to obtain an expression for a transition amplitude, from which we identify the classical electromagnetic fields induced by the background axion field. We confirm previous results, that if the spatial size $R$ of the applied static magnetic field is small compared to the axion Compton wavelength $λ$, the induced electric and magnetic fields are parametrically suppressed by the small numbers $(R/λ)^2$ and $R/λ$, respectively, relative to the case when $R$ is larger than $λ$. Our approach allows an intuitive interpretation in terms of 4-momentum conservation and momentum exchange via the photon propagator.

Comment on $Z'$'s and the H1 and ZEUS High $Q^2$ Anomalies

description: We investigate the effects of extra neutral gauge bosons on the high $Q^2$ region of the $e^+p \to e^+ X$ cross section at $\sqrt{s}=300$ GeV. We found that the only models with electroweak strength coupling, typical of extended gauge theories, that give a better fit to the H1 and ZEUS high $Q^2$ data than the standard model, are ruled out by existing data from the Tevatron. From general scaling arguments, using the allowed contact interactions, the only allowed models with $Z'$'s would be those with strong couplings although even in this case the statistical evidence is not compelling.

A Categorial Framework for Composition in Multiple Linguistic Domains
Creators: name: Bozsahin, Cem
name: Gocmen, Elvan
Publisher: name: arXiv
Year: 1995
Subjects: subject: Computation and Language (cs.CL)
subject: FOS: Computer and information sciences

description: This paper describes a computational framework for a grammar architecture in which different linguistic domains such as morphology, syntax, and semantics are treated not as separate components but compositional domains. Word and phrase formation are modeled as uniform processes contributing to the derivation of the semantic form. The morpheme, as well as the lexeme, has lexical representation in the form of semantic content, tactical constraints, and phonological realization. The motivation for this work is to handle morphology-syntax interaction (e.g., valency change in causatives, subcategorization imposed by case-marking affixes) in an incremental way. The model is based on Combinatory Categorial Grammars.

description: 1. The metabolic fate and urinary excretion of 2-bromophenol, a phenolic metabolite of bromobenzene, was investigated in male Sprague–Dawley rats following single intraperitoneal doses at either 0, 100, or 200 mg/kg. 2. Urine was collected for seven days and samples analysed using 1 H NMR spectroscopy, inductively coupled plasma (ICP)MS, and UPLC-MS. 3. 1 H NMR spectroscopy of the urine samples showed that, at these doses, 2-bromophenol had little effect on endogenous metabolite profiles, supporting histopathology and clinical chemistry data, which showed no changes associated with the administration of 2-bromophenol in this study. 4. The use of ICP-MS provided a means for the selective detection and quantification of bromine-containing species and showed that between 15 and 30% of the dose was excreted via the urine over 7 days of the study for both the 100 and 200 mg doses, respectively. 5. The bulk of the excretion of Br-containing material had occurred by 8 h post administration. UPLC-MS of urine revealed a number of metabolites of 2-bromophenol, with 2-bromophenol glucuronide and 2-bromophenol sulphate identified as the major species. A number of minor hydroxylated metabolites were also detected as their glucuronide, sulphate, or O-methyl conjugates. There was no evidence for the production of reactive metabolites.
