High-precision covariant one-boson-exchange potentials for np scattering below 350 MeV

description: All realistic potential models for the two-nucleon interaction are to some extent based on boson exchange. However, in order to achieve an essentially perfect fit to the scattering data, characterized by a chi2/Ndata ~ 1, previous potentials have abandoned a pure one boson-exchange mechanism (OBE). Using a covariant theory, we have found a OBE potential that fits the 2006 world np data below 350 MeV with a chi2/Ndata = 1.06 for 3788 data. Our potential has fewer adjustable parameters than previous high-precision potentials, and also reproduces the experimental triton binding energy without introducing additional irreducible three-nucleon forces.

A close look at how context of acquisition of previous languages influences third language pedagogy: Does one model fit all?

description: A significant proportion of college students in the United States have Spanish in their linguistic repertoire. Several language programs capitalize on these students' bilingual skills to offer them the opportunity to develop proficiency in additional languages, especially cognate systems that can be acquired faster, such as French, Italian, and Portuguese. In this article, I first offer a synopsis of the research that has been developed on the acquisition of cognate languages in general, and the acquisition of Portuguese by Spanish speakers in particular. I then focus on the main premises that are considered in the curriculum designed to teach Portuguese for Spanish speakers in educational settings in the United States, pinpointing a tendency to treat Spanish speakers as a homogeneous group. Finally, I focus on incipient research that points to differences in patterns of L3 acquisition by learners who speak Spanish as their first, second, or heritage language, and problematize the assumption that they make up a homogeneous group with similar pedagogical needs. While possible differences among L3 learners due to different contexts of acquisition of previous languages have been pointed out by previous research, only a few studies have investigated these dissimilarities. This article aims to contribute to this growing area of research by exploring important differences among English-Spanish bilingual learners of L3 Portuguese who acquired Spanish as their L2 or heritage language both in terms of their performance in class and in terms of their perception of the learning process through an examination of previous studies and incipient survey data. It concludes that while L2 Spanish speakers benefit more from explicit teaching due to previous experience as language learners that lead to a higher level of metalinguistic awareness, heritage Spanish speakers are less fluent in metalinguistic terminology and an explicit understanding of grammar, and as such benefit from more implicit, naturalistic activities that rely on their intuition. Lastly, a number of important implications for curricular adjustments that cater for both types of Spanish speakers in L3 Portuguese classes are offered.

description: Using the star formation rates from the SDSS galaxy sample, extracted using the MOPED algorithm, and the empirical Kennicutt law relating star formation rate to gas density, we calculate the time evolution of the gas fraction as a function of the present stellar mass. We show how the gas-to-stars ratio varies with stellar mass, finding good agreement with previous results for smaller samples at the present epoch. For the first time we show clear evidence for progressive gas loss with cosmic epoch, especially in low-mass systems. We find that galaxies with small stellar masses have lost almost all of their cold baryons over time, whereas the most massive galaxies have lost little. Our results also show that the most massive galaxies have evolved faster and turned most of their gas into stars at an early time, thus strongly supporting a downsizing scenario for galaxy evolution.

description: We calculate the magnetic field generated during bubble collisions in a first-order electroweak phase transition that may occur for some choices of parameters in the minimal supersymmetric Standard Model. We show that for sufficiently gentle collisions, where the Higgs field is relatively unperturbed in the bubble overlap region, the equations of motion can be linearized so that in the absence of fermions the charged W fields are the source of the electromagnetic current for generating the seed fields. Solutions of the equations of motion for the charged gauge fields and Maxwell's equations for the magnetic field in O(1,2) space-time symmetry are expressed in closed form by applying boundary conditions at the time of collision. Our results indicate that the magnetic fields generated by charged $W^{\pm}$ fields in the collision are comparable to those found in previous work. The magnetic fields so produced could seed galactic and extra-galactic magnetic fields observed today.

description: Polydispersity is inevitable in industrially produced polymers. Established theories of polymer dynamics and rheology, however, were mostly built on monodisperse linear polymers. Dynamics of polydisperse polymers is yet to be fully explored -- especially how chains of different lengths affect the dynamics of one another in a mixture. This study explored the dynamics of bidisperse polymer melts using molecular dynamics and a bead-spring chain model. Binary mixtures between a moderately entangled long-chain species and an unentangled or marginally entangled short-chain species were investigated. We found that adding short chains can significantly accelerate the dynamics of the long chains by substantially lessening their extent of entanglement. Meanwhile, although introducing long chains also hinders the motion of the short chains, it does not qualitatively alter the nature of their dynamics -- unentangled short chains still follow classical Rouse dynamics even in a matrix containing entangled chains. Detailed Rouse mode analysis was used to reveal the effects of entanglement at chain segments of different scales. Stress relaxation following a step shear strain was also studied and semi-empirical mixing rules that predict the linear viscoelasticity of polydisperse polymers based on that of monodisperse systems were evaluated with simulation results.

description: The article reports a study on plurilingual approaches (PA) of three multilingual teachers in three foreign language classrooms (English, German and Russian) at a Turkish state university. The qualitative study explored the attitudes of multilingual teachers to PA and the response of their L3/L3+ students ($N=5$) to the plurilingual practices in class. The perceptions of participants were investigated from the holistic paradigm in multilingualism. Data were collected through interviews and graphic elicitation tasks. Data were analyzed through content and visual-based analysis. The results indicated three main themes based on participants' perceptions of PA: (1) implementation, (2) benefits to learning and (3) the role of multilingual teachers in L3 Acquisition. Both teachers and students displayed positive attitudes in findings (1) and (2). However, participants’ perceptions were not homogeneous in finding (3), which revealed some issues. The overall findings suggest that multilingual teachers should play a crucial role in plurilingual and L3 classrooms in a Turkish context.

description: We compare H-alpha, radio continuum, and Spitzer Space Telescope (SST) images of 58 planetary nebulae (PNe) recently discovered by the Macquarie-AAO-Strasbo- urg H-alpha PN Project (MASH) of the SuperCOSMOS H-alpha Survey. Using InfraRed Array Camera (IRAC) data we define the IR colors of PNe and demonstrate good isolation between these colors and those of many other types of astronomical object. The only substantive contamination of PNe in the color-color plane we illustrate is due to YSOs. However, this ambiguity is readily resolved by the unique optical characteristics of PNe and their environs. We also examine the relationships between optical and MIR morphologies from 3.6 to 8.0um and explore the ratio of mid-infrared (MIR) to radio nebular fluxes, which is a valuable discriminant between thermal and nonthermal emission. MASH emphasizes late evolutionary stages of PNe compared with previous catalogs, enabling study of the changes in MIR and radio flux that attend the aging process. Spatially integrated MIR energy distributions were constructed for all MASH PNe observed by the GLIMPSE Legacy Project, using the H-alpha morphologies to establish the dimensions for the calculations of the Midcourse Space Experiment (MSX), IRAC, and radio continuum (from the Molonglo Observatory Synthesis Telescope and the Very Large Array) flux densities. The ratio of IRAC 8.0-um to MSX 8.3-um flux densities provides a measure of the absolute diffuse calibration of IRAC at 8.0 um. We independently confirm the aperture correction factor to be applied to IRAC at 8.0um to align it with the diffuse calibration of MSX. The result agrees with the recommendations of the Spitzer Science Center and with results from a parallel study of HII regions. These PNe probe the diffuse calibration of IRAC on a spatial scale of 9-77 arcsec.

CP Violation and Arrows of Time Evolution of a Neutral $K$ or $B$ Meson from an Incoherent to a Coherent State

description: We study the evolution of a neutral $K$ meson prepared as an incoherent equal mixture of $K^0$ and $\bar{K^0}$. Denoting the density matrix by $ρ(t) = {1/2} N(t) [\1 + \vecζ(t) \cdot \vecσ ] $, the norm of the state $N(t)$ is found to decrease monotonically from one to zero, while the magnitude of the Stokes vector $|\vecζ(t)|$ increases monotonically from zero to one. This property qualifies these observables as arrows of time. Requiring monotonic behaviour of $N(t)$ for arbitrary values of $γ_L, γ_S$ and $Δm$ yields a bound on the CP-violating overlap $δ= \braket{K_L}{K_S}$, which is similar to, but weaker than, the known unitarity bound. A similar requirement on $|\vecζ(t)|$ yields a new bound, $δ^2 < {1/2} (\frac{Δγ}{Δm}) \sinh (\frac{3π}{4} \frac{Δγ}{Δm})$ which is particularly effective in limiting the CP-violating overlap in the $B^0$-$\bar{B^0}$ system. We obtain the Stokes parameter $ζ_3(t)$ which shows how the average strangeness of the beam evolves from zero to $δ$. The evolution of the Stokes vector from $|\vecζ| = 0$ to $|\vecζ| = 1$ has a resemblance to an order parameter of a system undergoing spontaneous symmetry breaking.

An inexact Douglas-Rachford splitting method for solving absolute value equations

description: The last two decades witnessed the increasing of the interests on the absolute value equations (AVE) of finding $x\in\mathbb{R}^n$ such that $Ax-|x|-b=0$, where $A\in \mathbb{R}^{n\times n}$ and $b\in \mathbb{R}^n$. In this paper, we pay our attention on designing efficient algorithms. To this end, we reformulate AVE to a generalized linear complementarity problem (GLCP), which, among the equivalent forms, is the most economical one in the sense that it does not increase the dimension of the variables. For solving the GLCP, we propose an inexact Douglas-Rachford splitting method which can adopt a relative error tolerance. As a consequence, in the inner iteration processes, we can employ the LSQR method ([C.C. Paige and M.A. Saunders, ACM Trans. Mathe. Softw. (TOMS), 8 (1982), pp. 43--71]) to find a qualified approximate solution for each subproblem, which makes the cost per iteration very low. We prove the convergence of the algorithm and establish its global linear rate of convergence. Comparing results with the popular algorithms such as the exact generalized Newton method [O.L. Mangasarian, Optim. Lett., 1 (2007), pp. 3--8], the inexact semi-smooth Newton method [J.Y.B. Cruz, O.P. Ferreira and L.F. Prudente, Comput. Optim. Appl., 65 (2016), pp. 93--108] and the exact SOR-like method [Y.-F. Ke and C.-F. Ma, Appl. Math. Comput., 311 (2017), pp. 195--202] are reported, which indicate that the proposed algorithm is very promising. Moreover, our method also extends the range of numerically solvable of the AVE; that is, it can deal with not only the case that $\|A^{-1}\|<1$, the commonly used in those existing literature, but also the case where $\|A^{-1}\|=1$.

Debunking student teachers' beliefs regarding the target-language-only rule
Creators: name: Pierre-Luc Paquet
name: Woll, Nina
Publisher: name: Zenodo
Year: 2021

description: Despite the recognized usefulness of crosslinguistic interaction, additional language (LN) teachers seem to be resistant to opening this Pandora's box to more multilingual classroom practice. While the ultimate goal of the broader research project is to promote student teachers' reflective stance concerning the potential benefits of crosslinguistic pedagogy, this study examines their beliefs regarding the TL-only rule established in their respective programs. Forty student teachers from Quebec and Mexico completed a vignette-based questionnaire where they were asked to reflect on different situations focused on the use of other languages, including L1. Results suggest that while a monolingual bias is prevalent in the Quebec context, participants from Mexico appear to be more open to resorting to other languages in the classroom. However, responses from both populations suggest that this perceived usefulness is restricted to situations where L1 is used as a vehicle rather than a resource. Suggestions for addressing these issues in teacher education are explored and avenues for further research are provided.
Residual entropy in a model for the unfolding of single polymer chains

description: We study the unfolding of a single polymer chain due to an external force. We use a simplified model which allows to perform all calculations in closed form without assuming a Boltzmann-Gibbs form for the equilibrium distribution. Temperature is then defined by calculating the Legendre transform of the entropy under certain constraints. The application of the model is limited to flexible polymers. It exhibits a gradual transition from compact globule to rod. The boundary line between these two phases shows reentrant behavior. This behavior is explained by the presence of residual entropy.

description: Various holographic approaches to QCD in five dimensions are explored using input both from the putative non-critical string theory as well as QCD. It is argued that a gravity theory in five dimensions coupled to a dilaton and an axion may capture the important qualitative features of pure QCD. A part of the higher alpha' corrections are resummed into a dilaton potential. The potential is shown to be in one-to-one correspondence with the exact beta-function of QCD, and its knowledge determines the full structure of the vacuum solution. The geometry near the UV boundary is that of AdS_5 with logarithmic corrections reflecting the asymptotic freedom of QCD. We find that all relevant confining backgrounds have an IR singularity of the "good" kind that allows unambiguous spectrum computations. Near the singularity the 't Hooft coupling is driven to infinity. Asymptotically linear glueball masses can also be achieved. The classification of all confining asymptotics, the associated glueball spectra and meson dynamics are addressed in a companion paper, ArXiv:0707.1349

description: A higher order theory of dilaton gravity is constructed as a generalization of the Einstein-Lovelock theory of pure gravity. Its Lagrangian contains terms with higher powers of the Riemann tensor and of the first two derivatives of the dilaton. Nevertheless, the resulting equations of motion are quasi-linear in the second derivatives of the metric and of the dilaton. This property is crucial for the existence of brane solutions in the thin wall limit. At each order in derivatives the contribution to the Lagrangian is unique up to an overall normalization. Relations between symmetries of this theory and the O(d,d) symmetry of the string-inspired models are discussed.

description: Competitive random sequential adsorption on a line from a binary mix of incident particles is studied using both an analytic recursive approach and Monte Carlo simulations. We find a strong correlation between the small and the large particle distributions so that while both partial contributions to the fill factor fluctuate widely, the variance of the total fill factor remains relatively small. The variances of partial contributions themselves are quite different between the smaller and the larger particles, with the larger particle distribution being more correlated. The disparity in fluctuations of partial fill factors increases with the particle size ratio. The additional variance in the partial contribution of smaller particle originates from the fluctuations in the size of gaps between larger particles. We discuss the implications of our results to semiconductor high-energy gamma detectors where the detector energy resolution is controlled by correlations in the cascade energy branching process.

description: This paper is a continuation of ArXiv:0707.1324 where improved holographic theories for QCD were set up and explored. Here, the IR confining geometries are classified and analyzed. They all end in a "good" (repulsive) singularity in the IR. The glueball spectra are gaped and discrete, and they favorably compare to the lattice data. Quite generally, confinement and discrete spectra imply each other. Asymptotically linear glueball masses can also be achieved. Asymptotic mass ratios of various glueballs with different spin also turn out to be universal. Mesons dynamics is implemented via space filling D4-anti-D4 brane pairs. The associated tachyon dynamics is analyzed and chiral symmetry breaking is shown. The dynamics of the RR axion is analyzed, and the non-perturbative running of the QCD theta-angle is obtained. It is shown to always vanish in the IR.

Training teachers for the challenges of multilingual education

Publisher: name: Zenodo
Year: 2021

description: This chapter focuses on how trainee teachers are prepared to face the linguistic complexity they will encounter in classrooms in the Basque Autonomous Community (henceforth BAC) in Spain. Although Spanish is the home language for most children in the BAC, the overwhelming majority of parents choose Basque as language of instruction at pre-school and primary levels (Basque government 2018) independently of the language spoken at home, which means that Basque is mainly acquired through immersion programmes. The teacher training programme at Mondragon University aims at providing future pre-school and primary teachers with solid knowledge on language acquisition in bi/multilingual contexts. These future teachers are also made familiar with instruments for measuring children’s language development and, furthermore, they carry out a team-work project to be presented in English, containing data on children’s linguistic picture as well as reflections on their own linguistic skills and the utility of knowledge acquired for their future in multilingual education.

description: We show that nonparaxial polarized light beams propagating in a bulk nonlinear Kerr medium naturally exhibit a coupling between the motional and the polarization degrees of freedom, realizing a spin-orbit-coupled mixture of fluids of light. We investigate the impact of this mechanism on the Bogoliubov modes of the fluid, using a suitable density-phase formalism built upon a linearization of the exact Helmholtz equation. The Bogoliubov spectrum is found to be anisotropic, and features both low-frequency gapless branches and high-frequency gapped ones. We compute the amplitudes of these modes and propose a couple of experimental protocols to study their excitation mechanisms. This allows us to highlight a phenomenon of hybridization between density and spin modes, which is absent in the paraxial description and represents a typical fingerprint of spin-orbit coupling.

description: В статье рассматриваются актуальные вопросы защиты самобытной культуры коренных малочисленных народов Севера1 в контексте права интеллектуальной собственности. Отмечается, что актуальной проблемой для нормативного правового регулирования этого феномена является отражение в праве особенностей субъекта права интеллектуальной собственности (субъектом выступают не физические лица, а объединения малочисленных народов, в том числе их общины, наделенные правами юридического лица) и объектов права (т. е. результатов их интеллектуальной деятельности, таких как традиционные знания и умения и др.). Обычные права народов Севера, относящиеся к их культурному наследию, принадлежат всем членам объединения как носителям традиции народа, при этом содержание понятий «традиции» и «обычное право» не нашло закрепления в законодательстве. «Общинная» специфика права интеллектуальной собственности требует теоретического обоснования в категориях права и специального правового регулирования. В связи с этим необходимо разработать и утвердить единые международные стандарты и механизмы реализации права интеллектуальной собственности на традиционные знания и иные результаты интеллектуальной деятельности малочисленных народов Севера.
description: The article analyzes relevant issues of protecting the original culture of indigenous minorities of the North in the context of intellectual property law. The current issue for legal regulation of the phenomenon is the reflection in law of peculiarities of the subject of intellectual property rights (associations of minorities, inter alia communities that possess rights of a legal entity, and not individuals represent the subject) and objects of rights (i.e. results of their intellectual activity, such as traditional knowledge and skills, etc.). The customary rights of the peoples of the North, related to their cultural heritage, belong to all members of the association as bearers of the traditions of the people. At the same time, the content of traditions and regular law has not been enshrined in the legislation. The “community” specifics of the intellectual property law requires a theoretical justification in the categories of law and special legal regulation. In this regard, it is necessary to develop and approve the united international standards and mechanisms of implementation of intellectual property rights into the traditional knowledge or other results of intellectual activity of indigenous minorities of the North.
Infrared High-Resolution Spectroscopy of Post-AGB Circumstellar Disks. I. HR 4049 - The Winnowing Flow Observed?

description: High-resolution infrared spectroscopy in the 2.3-4.6 micron region is reported for the peculiar A supergiant, single-lined spectroscopic binary HR 4049. Lines from the CO fundamental and first overtone, OH fundamental, and several H2O vibration-rotation transitions have been observed in the near-infrared spectrum. The spectrum of HR 4049 appears principally in emission through the 3 and 4.6 micron region and in absorption in the 2 micron region. The 4.6 micron spectrum shows a rich 'forest' of emission lines. All the spectral lines observed in the 2.3-4.6 micron spectrum are shown to be circumbinary in origin. The presence of OH and H2O lines confirm the oxygen-rich nature of the circumbinary gas which is in contrast to the previously detected carbon-rich material. The emission and absorption line profiles show that the circumbinary gas is located in a thin, rotating layer near the dust disk. The properties of the dust and gas circumbinary disk and the spectroscopic orbit yield masses for the individual stars, M_AI~0.58 Msolar and M_MV~0.34 Msolar. Gas in the disk also has an outward flow with a velocity of $\gtrsim$ 1 km/s. The severe depletion of refractory elements but near-solar abundances of volatile elements observed in HR 4049 results from abundance winnowing. The separation of the volatiles from the grains in the disk and the subsequent accretion by the star are discussed. Contrary to prior reports, the HR 4049 carbon and oxygen isotopic abundances are typical AGB values: 12C/13C=6^{+9}_{-4} and 16O/17O>200.

description: The interplay between cosmological expansion and local attraction in a gravitationally bound system is revisited in various regimes. First, weakly gravitating Newtonian systems are considered, followed by various exact solutions describing a relativistic central object embedded in a Friedmann universe. It is shown that the ``all or nothing'' behaviour recently discovered (i.e., weakly coupled systems are comoving while strongly coupled ones resist the cosmic expansion) is limited to the de Sitter background. New exact solutions are presented which describe black holes perfectly comoving with a generic Friedmann universe. The possibility of violating cosmic censorship for a black hole approaching the Big Rip is also discussed.

A New TOA Localization and Synchronization System with Virtually Synchronized Periodic Asymmetric Ranging Network

description: In this article, we design a new time-of-arrival (TOA) system for simultaneous user device (UD) localization and synchronization with a periodic asymmetric ranging network, namely PARN. The PARN includes one primary anchor node (PAN) transmitting and receiving signals, and many secondary ANs (SAN) only receiving signals. All the UDs can transmit and receive signals. The PAN periodically transmits sync signal and the UD transmits response signal after reception of the sync signal. Using TOA measurements from the periodic sync signal at SANs, we develop a Kalman filtering method to virtually synchronize ANs with high accuracy estimation of clock parameters. Employing the virtual synchronization, and TOA measurements from the response signal and sync signal, we then develop a maximum likelihood (ML) approach, namely ML-LAS, to simultaneously localize and synchronize a moving UD. We analyze the UD localization and synchronization error, and derive the Cramer-Rao lower bound (CRLB). Different from existing asymmetric ranging network-based TOA systems, the new PARN i) uses the periodic sync signals at the SAN to exploit the temporal correlated clock information for high accuracy virtual synchronization, and ii) compensates the UD movement and clock drift using various TOA measurements to achieve consistent and simultaneous localization and synchronization performance. Numerical results verify the theoretical analysis that the new system has high accuracy in AN clock offset estimation and simultaneous localization and synchronization for a moving UD. We implement a prototype hardware system and demonstrate the feasibility and superiority of the PARN in real-world applications by experiments.
On the Entropy Function and the Attractor Mechanism for Spherically Symmetric Extremal Black Holes

description: In this paper we elaborate on the relation between the entropy formula of Wald and the "entropy function" method proposed by A. Sen. For spherically symmetric extremal black holes, it is shown that the expression of extremal black hole entropy given by A. Sen can be derived from the general entropy definition of Wald, without help of the treatment of rescaling the AdS_2 part of near horizon geometry of extremal black holes. In our procedure, we only require that the surface gravity approaches to zero, and it is easy to understand the Legendre transformation of f, the integration of Lagrangian density on the horizon, with respect to the electric charges. Since the Noether charge form can be defined in an "off-shell" form, we define a corresponding entropy function, with which one can discuss the attractor mechanism for extremal black holes with scalar fields.

description: We expand previous work on an inverse approach to Einstein Field Equations where we include fluids with energy flux and consider the vanishing of the anisotropic stress tensor. We consider the approach using warped product spacetimes of class $B_1$. Although restricted, these spacetimes include many exact solutions of interest to compact object studies and to cosmological models studies. The question explored here is as follows: given a spacetime metric, what fluid flow (timelike congruence), if any, could generate the spacetime via Einstein's equations. We calculate the flow from the condition of a vanishing anisotropic stress tensor and give results in terms of the metric functions in the three canonical types of coordinates. A condition for perfect fluid sources is also provided. The framework developed is algorithmic and suited for the study and validation of exact solutions using computer algebra systems. The framework can be applied to solutions in comoving and non-comoving frames of reference, and examples in different types of coordinates are worked out.

description: Rydberg electromagnetically induced transparency (EIT) enables realization of atom-based SI-traceable microwave (MW) sensing, imaging and communication devices by exploiting the strong microwave electric dipole coupling of highly excited Rydberg states. Essential to the development of robust devices is a careful characterization of sensor performance and systematic uncertainties. In this work we present a comparison of microwave-induced EIT splitting in a cesium atomic vapor for four possible Rydberg couplings $65S_{1/2}\rightarrow 65P_{1/2}$, $66S_{1/2}\rightarrow 66P_{3/2}$, $79D_{5/2}\rightarrow 81P_{3/2}$ and $62D_{5/2}\rightarrow 60F_{7/2}$ at microwave transition frequencies around 13 GHz. Our work highlights the impact of multi-photon couplings to neighboring Rydberg states in breaking both the symmetry and linearity of the observed splitting, with excellent agreement between experimental observations and a theoretical model accounting for multi-photon couplings. We identify an optimal angular state choice for robust microwave measurements, as well as demonstrating a new regime in which microwave polarization can be measured.

description: In the stripe-ordered state of a strongly-correlated two-dimensional electronic system, under a set of special circumstances, the superconducting condensate, like the magnetic order, can occur at a non-zero wave-vector corresponding to a spatial period double that of the charge order. In this case, the Josephson coupling between near neighbor planes, especially in a crystal with the special structure of La_{2-x}Ba_xCuO_4, vanishes identically. We propose that this is the underlying cause of the dynamical decoupling of the layers recently observed in transport measurements at x=1/8.
