description: Piezoresponse Force Spectroscopy (PFS) has emerged as a powerful technique for probing highly localized switching behavior and the role of microstructure and defects on switching. The application of a dc bias to a scanning probe microscope tip in contact with a ferroelectric surface results in the nucleation and growth of a ferroelectric domain below the tip, resulting in changes in local electromechanical response. Resulting hysteresis loops contains information on local ferroelectric switching behavior. The signal in PFS is the convolution of the volume of the nascent domain and the probing volume of the tip. Here, we analyze the signal formation mechanism in PFS by deriving the main parameters of domain nucleation in a semi-infinite material and establishing the relationships between domain parameters and PFM signal using a linear Greens function theory. The effect of surface screening and finite Debye length on the switching behavior is established. In particular, we predict that the critical nucleus size in PFM is controlled by the surface screening mechanism and in the absence of screening, tip-induced switching is impossible. Future prospects of PFS to study domain nucleation in the vicinity of defects, local switching centers in ferroelectrics, and unusual polarization states in low-dimensional ferroelectrics are discussed.

description: The full 2D analysis of roughness profiles of fracture surfaces resulting from quasi-static crack propagation in gelatin gels reveals an original behavior characterized by (i) strong anisotropy with maximum roughness at $V$-independent symmetry-preserving angles, (ii) a sub-critical instability leading, below a critical velocity, to a cross-hatched regime due to straight macrosteps drifting at the same magic angles and nucleated on crack-pinning network inhomogeneities. Step height values are determined by the width of the strain-hardened zone, governed by the elastic crack blunting characteristic of soft solids with breaking stresses much larger that low strain moduli.

description: Topic drift is a common phenomenon in multi-turn dialogue. Therefore, an ideal dialogue generation models should be able to capture the topic information of each context, detect the relevant context, and produce appropriate responses accordingly. However, existing models usually use word or sentence level similarities to detect the relevant contexts, which fail to well capture the topical level relevance. In this paper, we propose a new model, named STAR-BTM, to tackle this problem. Firstly, the Biterm Topic Model is pre-trained on the whole training dataset. Then, the topic level attention weights are computed based on the topic representation of each context. Finally, the attention weights and the topic distribution are utilized in the decoding process to generate the corresponding responses. Experimental results on both Chinese customer services data and English Ubuntu dialogue data show that STAR-BTM significantly outperforms several state-of-the-art methods, in terms of both metric-based and human evaluations.

description: In this paper we will explore two different proposals for the action for causal sets: the Benincasa-Dowker action and a modified version of the chain action. We propose a variational principle for two-dimensional causal sets and use it for both actions to determine which causal sets at least on average satisfy a discrete version of the Einstein equation. Specifically, we test this method on causal sets embedded in 2d Minkowski, de Sitter, and anti-de Sitter spacetimes and compare these results to the most prominent nonmanifoldlike causal sets, Kleitman-Rothschild causal sets.

Biological abstractions of parasitic and parasitoid predation upon organisms are demonstrably a very useful model for the study, forensic analysis, and recovery from some frequently seen types of organizational dysfunction. Future research presents opportunities to refine modeling, forensic techniques, and develop a robust and detailed methodology for recovering organizations, damaged by the destructive effects of this type of organizational dysfunction.

description: This timely volume emerged out of the conference "Obama and the Paradigm Shift", organized in the summer of 2011 at the University of Giessen, and offers 10 essays that ask if and to what extent Barack and Michelle Obama caused a paradigm shift in the U.S. and Germany in terms of gender, race, and political divisiveness. Despite not always being consistent, especially not in terms of its self-declared transcultural approach, this collection of essays offers lively, differentiated, multifaceted, and critical readings of the presidency of the Obamas. As such, it provides enrichment for the current, deeply polarized book market on the Obamas.

The Variation of Galaxy Morphological Type with the Shear of Environment

description: Recent N-body simulations have shown that the assembly history of galactic halos depend on the density of large-scale environment. It implies that the galaxy properties like age and size of bulge may also vary with the surrounding large-scale structures, which are characterized by the tidal shear as well as the density. By using a sample of 15,882 well-resolved nearby galaxies from the Tully Catalog and the real space tidal field reconstructed from the 2Mass Redshift Survey (2MRS), we investigate the dependence of galaxy morphological type on the shear of large-scale environment where the galaxies are embedded. We first calculate the large scale dimensionless overdensities (d) and the large-scale ellipticities (e) of the regions where the Tully galaxies are located and classify the Tully galaxies according to their morphological types and create subsamples selected at similar value of d but span different ranges in e. We calculate the mean ellipticity, , averaged over each subsample and find a signal of variation of with galaxy morphological type: For the case of 0.5<=d<=1.0, the ellipticals are found to be preferentially located in the regions with low ellipticity. For the case of -0.3<=d<=0.1, the latest-type spirals are found to be preferentially located in the regions with high ellipticity. The null hypothesis that the mean ellipticities of the regions where the ellipticals and the latest type spirals are located are same as the global mean ellipticity averaged over all types is rejected at 3 sigma level when -0.3<=d<=0.1. Yet, no signal of galaxy-shear correlation is found in the highly overdense/underdense regions. The observed trend suggests that the formation epochs of galactic halos might be a function not only of halo mass and large-scale density but also of large-scale shear.

The ›F-Words‹: Postfeminism and the (Re-)Negotiation of Femaleness, Femininity, and Feminism in Popular Culture
Creators: name: Heise, Franka
Publisher: name: KULT_online
Year: 2012

description: Stéphanie Genz' and Anthea Taylor's works can both be regarded as valuable contributions to the ongoing discussion about the nature of postfeminism. Where Genz' work consists of a comprehensive and broad analysis of the different ways (post)femininities are presented in contemporary (foremost U.S.) popular culture, Taylor concentrates on how the figure of the single woman can be located within postfeminist media discourses. Both books are based on the argument that contemporary representations of (post-)femininities are determined by an ambivalent relationship of femininity and feminism, simultaneously re-appropriating feminism in the form of an emphasis on power, independence, and personal freedom as well as repudiating feminism as outdated, victimizing, and 'killjoy' (see Ahmed 2010). Covering a wide range of pop culture examples, from Sex and the City, Bridget Jones, and Fatal Attraction to literary texts, self-help books, blogs, and reality TV shows, both authors conduct their analysis via a close reading of selected cultural texts. While Genz tries to untangle how postfeminism shapes the (re)negotiation of the 'f-words': femaleness (as embodied subject position), femininity (as performance of socially constructed gender), and feminism, Taylor elaborates how postfeminism functions to regulate the re-configuration of the 'spinster to the Singleton'.

We study 10 industry sectors through the lens of 6 (so called) emerging countries: China, Brazil, India, Mexico, Indonesia and Turkey, over the 2000 to 2014 period. Using a panel data framework, our study sheds light on a significant effect of Local Investor Sentiments on expected returns for basic materials, consumer goods, industrial, and financial industries. Moreover, our results suggest that from Global Investor Sentiments alone, one cannot predict expected stock returns in these markets.

description: We argue that fractional order (FO) differential equations are more suitable to model complex adaptive systems (CAS). Hence they are applied in replicator equations for non-cooperative game. Rock-Scissors-Paper game is discussed. It is known that its integer order model does not have a stable equilibrium. Its fractional order model is shown to have a locally asymptotically stable internal solution. A FO asymmetric game is shown to have a locally asymptotically stable internal solution. This is not the case for its integer order counterpart.

description: We present a new method to renormalize stochastic differential equations subjected to multiplicative noise. The method is based on the widely used concept of effective potential in high energy physics, and has already been successfully applied to the renormalization of stochastic differential equations subjected to additive noise. We derive a general formula for the one-loop effective potential of a single ordinary stochastic differential equation (with arbitrary interaction terms) subjected to multiplicative Gaussian noise (provided the noise satisfies a certain normalization condition). To illustrate the usefulness (and limitations) of the method, we use the effective potential to renormalize a toy chemical model based on a simplified Gray-Scott reaction. In particular, we use it to compute the scale dependence of the toy model's parameters (in perturbation theory) when subjected to a Gaussian power-law noise with short time correlations.

description: We study the detection of weak coherent forces by means of an optomechanical device formed by a highly reflecting isolated mirror shined by an intense and highly monochromatic laser field. Radiation pressure excites a vibrational mode of the mirror, inducing sidebands of the incident field, which are then measured by heterodyne detection. We determine the sensitivity of such a scheme and show that the use of an entangled input state of the two sideband modes improves the detection, even in the presence of damping and noise acting on the mechanical mode.

Superstring in the plane-wave background with RR flux as a conformal field theory

Year: 2008
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study the type IIB superstring in the plane-wave background with Ramond-Ramond flux and formulate it as an exact conformal field theory in operator formalism. One of the characteristic features of the superstring in a consistent background with RR flux, such as the AdS5xS5 and its plane-wave limit, is that the left- and the right-moving degrees of freedom on the worldsheet are inherently coupled. In the plane-wave case, it is manifested in the well-known fact that the Green-Schwarz formulation of the theory reduces to that of free massive bosons and fermions in the light-cone gauge. This raises the obvious question as to how this feature is reconciled with the underlying conformal symmetry of the string theory. By adopting the semi-light-cone conformal gauge, we will show that, despite the existence of such non-linear left-right couplings, one can construct two independent sets of quantum Virasoro operators in terms of fields obeying the free-field commutation relations. Furthermore, we demonstrate that the BRST cohomology analysis reproduces the physical spectrum obtained in the light-cone gauge.

The exercise of daily life: towards an understanding of physical activity in the daily lives of low-income single mothers
Creators: name: Dyck, Lesley Ann
Publisher: name: University of British Columbia
Year: 2009

description: Low-income women are more likely to experience poor health and less likely to be physically active. However, most of the research has only considered physical activity from the culturally dominant norm of fitness, recreation and leisure. Activity performed in the context of daily life outside the program setting has not been investigated, especially not for low-income single mothers who are marginalized within the dominant culture. The purpose of this study is to explore the meaning and practice of physical activity in the daily lives of low-income single mothers. Three women between the ages of 28 and 32 participated in this study, recruited from a housing project for low-income single mothers. A variety of established qualitative research methods were used to identify the practice of physical activity in daily life and investigate personal meanings. These methods included: a discussion group, individual in-depth interviews, and on-going field notes. Additional methods designed and assessed included: community assessment, community mapping exercise, physical activity logs, and participant observation. Analysis consisted of mapping data themes and interpreting these themes using a organizing framework based on the literature. Four primary analytic concepts for understanding the meaning and practice of physical activity in daily life emerged: work and leisure, well-being and health, quality of life, and power and control: This analysis, based on the organizing framework and use of new data collection techniques, makes an important contribution by challenging some of the dominant myths in the literature related to physical activity and low-income women. The assumption that low-income single mothers are the least active population needs to be revisited. Future research must also consider that physical activity may not be as stable as defined by the social-class literature. The practice of physical activity may both enhance and constrain positive health, as well as be experienced as both conforming to and resisting social norms. Finally, the negotiation of power at the level of the body demonstrates the potential for physical activity to contribute to self-esteem and personal empowerment.

We analyze a fine-grained latticization of the hyperbolic disk in the context of an effective theory for massive gravitons. We find that in six-dimensional warped hyperbolic space, lattice gravity appears near the boundary of the disk more weakly coupled than in discretized five-dimensional flat or warped space. Specifically, near the IR branes, the local strong coupling scale can become as large as the local Planck scale.

description: La irrupción de los denominados nuevos cines en los años sesenta del pasado siglo, así como las producciones independientes en el cine norteamericano, se han ido multiplicando las etiquetas para conceptualizar un cine que escapa con soltura a las clasificaciones formuladas en la política hollywoodiense de los géneros, férreamente establecidas durante décadas. Las teorías del autor-director cinematográfico se desarrollan para este nuevo cine, iniciador de la modernidad cinematográfica, a finales de los años cincuenta y, especialmente a principios de los sesenta, formadas por una constelación cultural que incluía revistas cinematográficas, cineclubes, la filmotecas y festivales de cine. Por importancia estética y creativa, por la aportación y exaltación de la figura del autor, por la introducción de nuevas temáticas o simplemente por su visión temática y forma anticipatoria existe un cierto consenso en la historiografía cinematográfica sobre un periodo que alumbra un nuevo tipo de cine cada vez más alejado de los esquemas clásicos. Se han acuñado para él etiquetas como modernidad o contemporaneidad cinematográfica, post cine, cine no convencional, contracine, cine posmoderno o narración postclásica, entre otras, para ilustrar un cine que, comenzando a mediados del siglo pasado, aceleró sus peculiares relaciones de amor-odio con el clasicismo cinematográfico y con el cine neoprimitivo en la década de los noventa.

description: Models with gauge-Higgs unification on a flat space are typically affected by common problems, the main of which are the prediction of a too small top and Higgs mass and a too low compactification scale. We show how, by breaking the SO(4,1) Lorentz symmetry in the bulk and introducing a Z_2 ``mirror'' symmetry, a potentially realistic model arises, in which all these problems are solved.

description: In this paper, we establish blow-up results for the semilinear wave equation in generalized Einstein-de Sitter spacetime with nonlinearity of derivative type. Our approach is based on the integral representation formula for the solution to the corresponding linear problem in the one-dimensional case, that we will determine through Yagdjian's Integral Transform approach. As upper bound for the exponent of the nonlinear term, we discover a Glassey-type exponent which depends both on the space dimension and on the Lorentzian metric in the generalized Einstein-de Sitter spacetime.

description: In case-based reasoning, the adaptation step depends in general on domain-dependent knowledge, which motivates studies on adaptation knowledge acquisition (AKA). CABAMAKA is an AKA system based on principles of knowledge discovery from databases. This system explores the variations within the case base to elicit adaptation knowledge. It has been successfully tested in an application of case-based decision support to breast cancer treatment.

description: We investigate the crystal structure, magnetic properties, and crystalline-electric field of tetragonal, $I4_1/amd$, NaCeO$_2$. In this compound, Ce$^{3+}$ ions form a tetragonally elongated diamond lattice coupled by antiferromagnetic interactions ($Θ_{CW} = -7.69$ K) that magnetically order below $T_N = 3.18$ K. The Ce$^{3+}$ $J = 5/2$ crystalline-electric field-split multiplet is studied via inelastic neutron scattering to parameterize a $J_{eff} = 1/2$ ground state doublet comprised of states possessing mixed $|m_z \rangle$ character. Neutron powder diffraction data reveal the onset of $A$-type antiferromagnetism with $μ=0.57(2)$ $μ_B$ moments aligned along the $c$-axis. The magnetic structure is consistent with the expectations of a frustrated Heisenberg $J_1$-$J_2$ model on the elongated diamond lattice with effective exchange values $J_1 > 4 J_2$ and $J_1 > 0$.

description: We investigate the effect of quenched spatial disordered hopping rates on the characteristics of the asymmetric simple exclusion process (ASEP) with open boundaries both numerically and by extensive simulations. Disorder averages of the bulk density and current are obtained in terms of various input and output rates. We study the binary and uniform distributions of disorder. It is verified that the effect of spatial inhomogeneity is generically to enlarge the size of the maximal current phase. This is in accordance with the mean field results obtained by Harris and Stinchcombe. Furthermore, we obtain the dependence of the current and the bulk density on the characteristics of the disorder distribution function. It is shown that the impact of disorder crucially depends on the particle input and out rates. In some situations, disorder can constructively enhance the current.

description: This study investigate the effectiveness of using Deep Learning (DL) for the classification of planetary nebulae (PNe). It focusses on distinguishing PNe from other types of objects, as well as their morphological classification. We adopted the deep transfer learning approach using three ImageNet pre-trained algorithms. This study was conducted using images from the Hong Kong/Australian Astronomical Observatory/Strasbourg Observatory H-alpha Planetary Nebula research platform database (HASH DB) and the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS). We found that the algorithm has high success in distinguishing True PNe from other types of objects even without any parameter tuning. The Matthews correlation coefficient is 0.9. Our analysis shows that DenseNet201 is the most effective DL algorithm. For the morphological classification, we found for three classes, Bipolar, Elliptical and Round, half of objects are correctly classified. Further improvement may require more data and/or training. We discuss the trade-offs and potential avenues for future work and conclude that deep transfer learning can be utilized to classify wide-field astronomical images.

description: The photospheric metal pollution of white dwarfs is now well-established as the signature of the accretion of planetary debris. However, the origin of the trace hydrogen detected in many white dwarfs with helium atmospheres is still debated. Here, we report the analysis of GD424: a metal-polluted, helium-atmosphere white dwarf with a large amount of trace hydrogen. We determined the atmospheric parameters using a hybrid analysis that combines the sensitivity of spectroscopy to the atmospheric composition, $\log(\mathrm{H/He})$, with that of photometry and astrometry to the effective temperature, $T_{\mathrm{eff}}$, and surface gravity, $\log g$. The resulting white dwarf mass, radius, and cooling age are $M_{\mathrm{WD}}=0.77\pm0.01\,\mathrm{M}_{\odot}$, $R_{\mathrm{WD}}=0.0109\pm0.0001\,\mathrm{R}_{\odot}$, and $τ_\mathrm{cool}=215\pm10$ Myr, respectively. We identified and measured the abundances of 11 photospheric metals and argue that the accretion event is most likely either in the increasing or steady state, and that the disrupted planetesimal resembles either CI chondrites or the bulk Earth in terms of its composition. We suggest that the observed $1.33\times 10^{22}$ g of trace hydrogen in GD424 were at least partly acquired through accretion of water-rich planetary debris in an earlier accretion episode.

description: RESUMEN: Se presenta un modelo de métricas responsables diseñado con el propósito de observar el desempeño de publicaciones para observar los aportes fundamentales de una publicación a la construcción de comunidad científica. Este estudio demuestra que la revista Redes ha sido nodal en la conformación de la comunidad luso e hispanoparlante alrededor del ARS. Se hizo un trabajo de búsqueda, recuperación y normalización de todos los artículos y citas, desde 2002 hasta 2020, con datos de Google Scholar. El modelo diseñado da respuesta a dos preguntas: (1) A partir del cálculo del índice H, ¿cuáles son los factores que han permitido el crecimiento del impacto de la revista?; (2) ¿Cuáles han sido los aportes de la revista Redes en la constitución de pilares geográficos e institucionales para la expansión de la comunidad del ARS? El análisis de los resultados mostró que se ha dado un crecimiento paulatino de la comunidad luso e hispanoparlante alrededor de la revista; el alcance geográfico con más impacto se da en LAC y la península Ibérica, con un interesante crecimiento global, y que los usos de los artículos no son solo para la investigación, pues la formación tiene un peso importante. ABSTRACT: This research presents a model of responsible metrics designed to observe Revista Redes's fundamental contributions to the social network analysis community. This study shows that the journal Redes has fulfilled its purpose of offering research results from the Ibero-American world and has also been central in shaping the Portuguese and Spanish-speaking community around the ARS. A process of information retrieval work was carried out on all articles and citations, from 2002 to 2020, using data from Google Scholar. The designed model answers two questions: (1) From the calculation of the H index, what are the factors that have allowed the impact of the journal to grow? (2) What have been the contributions of Redes Journal in the constitution of geographic and institutional pillars for the expansion of the ARS community? Findings showed: a gradual growth of the Portuguese and Spanishspeaking community around the magazine; a geographical scope with the most significant impact in LAC and the Iberian Peninsula; and uses of the articles are not only for research, since training new researchers has a critical weight.
Possible Evolution of Minifilament-Eruption-Produced Solar Coronal Jets, Jetlets, and Spicules, into Magnetic-Twist-Wave "Switchbacks" Observed by the Parker Solar Probe (PSP)

description: Many solar coronal jets result from erupting miniature-filament ("minifilament") magnetic flux ropes that reconnect with encountered surrounding far-reaching field. Many of those minifilament flux ropes are apparently built and triggered to erupt by magnetic flux cancelation. If that cancelation (or some other process) results in the flux rope's field having twist, then the reconnection with the far-reaching field transfers much of that twist to that reconnected far-reaching field. In cases where that surrounding field is open, the twist can propagate to far distances from the Sun as a magnetic-twist Alfvenic pulse. We argue that such pulses from jets could be the kinked-magnetic-field structures known as "switchbacks," detected in the solar wind during perihelion passages of the Parker Solar Probe (PSP). For typical coronal-jet-generated Alfvenic pulses, we expect that the switchbacks would flow past PSP with a duration of several tens of minutes; larger coronal jets might produce switchbacks with passage durations ~1hr. Smaller-scale jet-like features on the Sun known as "jetlets" may be small-scale versions of coronal jets, produced in a similar manner as the coronal jets. We estimate that switchbacks from jetlets would flow past PSP with a duration of a few minutes. Chromospheric spicules are jet-like features that are even smaller than jetlets. If some portion of their population are indeed very-small-scale versions of coronal jets, then we speculate that the same processes could result in switchbacks that pass PSP with durations ranging from about ~2 min down to tens of seconds.

description: В данной статье представлено исследование, направленное на усовершенствование принципов пропорционального лечения анемии у пациентов с ревматоидным артритом (РА), с учетом ее распространенности и фенотипов гаптоглобина. В период с 2016 по 2020 год было проведено исследование, в котором приняли участие 214 пациентов с диагнозом РА, проходивших лечение в кардиоревматологическом отделении Самаркандского городского медицинского объединения, и 20 здоровых людей, составивших контрольную группу. Для диагностики использовались общепринятые клинические, лабораторные и инструментальные методы, включая общий клинический анализ крови, показатели фибриногена и С-реактивного белка, а также исследование уровня железа и его белков-переносчиков. Результаты исследования показывают необходимость индивидуализированного подхода к лечению анемии у больных РА, что позволит улучшить клинические исходы и качество жизни пациентов.
