description: We have made spectroscopic identifications of 39 additional quasar candidates from the Deep Multicolor Survey (DMS) of Hall et al. (1996, ApJ, 462, 614, astro-ph/9512052). We have identified 9 new quasars with 0.3 < z < 2.8 and 16.8 < B < 21.6, all from the group of candidates with ultraviolet excess (UVX). No new quasars with z > 3 were found among the observed candidates selected due to their red (B-R) and (V-R) colors. As a result, there are now 55 confirmed quasars in the survey: 42 with 0.3 < z < 2, nine with 2 < z < 3, three with 3 < z < 4, and 1 at z = 4.3. One new quasar, DMS 0059-0055, is very bright with B=16.8 and z=0.3, making its detection by our survey very unexpected. Including this new spectroscopy, the results of the DMS are converging with the predicted space densities of other surveys. In particular, we no longer find an excess of quasars with z < 2.3 and B < 21 in the survey over predictions based on models by Koo & Kron. Also, the excess in the number of quasars seen at z > 3 over predictions based on models by Warren, Hewett, & Osmer is less than previously suggested. We also demonstrate the success of our quasar color modeling which is important in assessing the completeness of our survey.

This research article examines the challenges encountered and the measures adopted during this transition, with special reference to Deoghar, Jharkhand. Through a mixed-methods approach, involving primary and secondary data collection, insights from 100 respondents are analyzed. The findings highlight the hindrances faced by educators, students, and institutions, along with suggested strategies to address these challenges and enhance the effectiveness of online education.
The Properties of Poor Groups of Galaxies: II. X-ray and Optical Comparisons

description: We use ROSAT PSPC data to study the X-ray properties of a sample of twelve poor groups that have extensive membership information (Zabludoff and Mulchaey 1997; Paper I). Diffuse X-ray emission is detected in nine of these groups. In all but one of the X-ray detected groups, the X-ray emission is centered on a luminous elliptical galaxy. Fits to the surface brightness profiles of the X-ray emission suggest the presence of two X-ray components in these groups. The first component is centered on the central elliptical galaxy. The location and extent of this component, combined with its X-ray temperature and luminosity, favor an origin in the interstellar medium of the central galaxy. Alternatively, the central component may be the result of a large-scale cooling flow. The second X-ray component is detected out to a radius of at least 100-300 kpc. This component follows the same relationships found among the X-ray temperature, X-ray luminosity and optical velocity dispersion of rich clusters. This result suggests that the X-ray detected groups are low-mass versions of clusters and that the extended gas component can properly be called the intragroup medium, in analogy to the intracluster medium in clusters. We also find a trend for the position angle of the optical light in the central elliptical galaxy to align with the position angle of the large-scale X-ray emission. (Abridged)

PARENTAL INVOLVEMENT IN PRIMARY EDUCATION IN UZBEKISTAN
Creators: name: Aziza Hayitova student at Karshi State University
Publisher: name: Zenodo
Year: 2024

description:        The original concept considered in this work is to point out the role of parental participation in their child’s primary education.

        This study aims to answer the following research questions:

1. What is parental involvement itself?!

2. Why parental caring is crucial for education?!

3. How school administrations in Uzbekistan can involve parents to their child’s education?!

       Jane D. Hull says: "At the end of the day, the most overwhelming key to a child’s success is the positive involvement of parents." [] Parental involvement in education is the parentsʼ role in their childʼs learning and it aids learners to achieve good behaviour, development of their academic knowledge and gaining success at school. With parentsʼ assistance children can adapt to the school life easily and they also aid young learners to strengthen what they have learnt at school. Especially it should be stressed that, some of the ways for involving parents into primary education are also offered.

From POS tagging to dependency parsing for biomedical event extraction

subject: FOS: Computer and information sciences

description: Background: Given the importance of relation or event extraction from biomedical research publications to support knowledge capture and synthesis, and the strong dependency of approaches to this information extraction task on syntactic information, it is valuable to understand which approaches to syntactic processing of biomedical text have the highest performance. Results: We perform an empirical study comparing state-of-the-art traditional feature-based and neural network-based models for two core natural language processing tasks of part-of-speech (POS) tagging and dependency parsing on two benchmark biomedical corpora, GENIA and CRAFT. To the best of our knowledge, there is no recent work making such comparisons in the biomedical context; specifically no detailed analysis of neural models on this data is available. Experimental results show that in general, the neural models outperform the feature-based models on two benchmark biomedical corpora GENIA and CRAFT. We also perform a task-oriented evaluation to investigate the influences of these models in a downstream application on biomedical event extraction, and show that better intrinsic parsing performance does not always imply better extrinsic event extraction performance. Conclusion: We have presented a detailed empirical study comparing traditional feature-based and neural network-based models for POS tagging and dependency parsing in the biomedical context, and also investigated the influence of parser selection for a biomedical event extraction downstream task. Availability of data and material: We make the retrained models available at https://github.com/datquocnguyen/BioPosDep

description: According to a conjecture recently put forward in arXiv:1806.08362, the scalar potential $V$ of any consistent theory of quantum gravity satisfies a bound $|\nabla V|/V \geq {\cal O}(1)$. This forbids dS solutions and supports quintessence models of cosmic acceleration. Here we point out that in the simplest models incorporating the Standard Model in addition to quintessence, with the two sectors decoupled as suggested by observations, the proposed bound is violated by 50 orders of magnitude. However, a very specific coupling between quintessence and just the Higgs sector may still be allowed and consistent with the conjecture.

description: We study if the neutrino mixing parameters suggested by the atmospheric neutrino anomaly imply chemical equilibrium between mu- and tau-flavored leptons in a supernova (SN) core. The initial flavor-conversion rate would indeed be fast if the nu_mu-nu_tau-mixing angle were not suppressed by second-order refractive effects. The neutrino diffusion coefficients are different for nu_mu, anti-nu_mu, nu_tau and anti-nu_tau so that neutrino transport will create a net mu and tau lepton number density. This will typically lead to a situation where the usual first-order refractive effects dominate, further suppressing the rate of flavor conversion. Altogether, neutrino refraction has the nontrivial consequence of guaranteeing the separate conservation of e, mu, and tau lepton number in a SN core on the infall and cooling time scales, even when neutrino mixing angles are large.

Influence of fluids on $V_\mathrm{P}/V_\mathrm{S}$ ratio: Increase or decrease?

Publisher: name: arXiv
Year: 2018
Subjects: subject: Geophysics (physics.geo-ph)
subject: FOS: Physical sciences

description: The evolution of $V_\mathrm{P}/V_\mathrm{S}$ with increasing fluid-saturated porosity is computed for isotropic rocks containing spheroidal pores. $V_\mathrm{P}/V_\mathrm{S}$ is shown to either decrease or increase with increasing porosity, depending on the aspect ratio $α$ of the pores, fluid to solid bulk modulus ratio $ζ$, and initial Poisson's ratio $ν_0$ of the solid. A critical initial Poisson's ratio $ν_\mathrm{0,crit}$ is computed, separating cases where $V_\mathrm{P}/V_\mathrm{S}$ increases (if $ν_0ν_\mathrm{0,crit}$) with increasing porosity. For thin cracks and highly compressible fluids, $ν_\mathrm{0,crit}$ is approximated by $0.157\,ζ/α$, whereas for spherical pores $ν_\mathrm{0,crit}$ is given by $0.2 + 0.8ζ$. If $ν_0$ is close to $ν_\mathrm{0,crit}$, the evolution of $V_\mathrm{P}/V_\mathrm{S}$ with increasing fluid-saturated porosity is near neutral and depends on subtle changes in pore shape and fluid properties. This regime is found to be relevant to partially dehydrated serpentinites in subduction zone conditions (porosity of aspect ratio near 0.1 and $ζ$ in the range 0.01--0.1), and makes detection of these rocks and possibly elevated fluid pressures difficult from $V_\mathrm{P}/V_\mathrm{S}$ only.

description: The cluster Abell 2199 is one of the prototypical ``cooling flow'' clusters. Its central cD galaxy is host to a steep-spectrum radio source, of the type associated with cooling cores. In this paper we combine radio data with new ROSAT HRI data to show that conditions in its inner core, less than 50 kpc, are complex and interesting. Energy and momentum flux from the radio jet have been significant in the dynamics of the gas in the core. In addition, the Faraday data detects a dynamically important magnetic field there. The core of the X-ray luminous gas is not a simple, spherically symmetric cooling inflow. In addition, we believe the X-ray gas has had strong effects on the radio source. It seems to have disrupted the jet flow, which has led to dynamical history very different from the usual radio galaxy. This particular source is much younger than the galaxy, which suggests the disruptive effects lead to an on-off duty cycle for such sources.

description: This article examines multilingual commercial films by Pakistani women screenwriters, directors, and producersfrom Sindh, Punjab and Khyber Pakhtunkhwa (KPK). Against the backdrop of political inconsistency, some eighty women have made about three hundred commercial films in Pakistan since 1947. The entry examines the content of women’s films against the political backdrop of Pakistan. Women made romantic musicals or mixed genres—romantic with social, fiction, fantasy, folklore, crime, or history—whose renditions cover Sindhi folklores, Pashto film crimes, Punjabi liberalism, and Urdu traditionalism.The entry finds that women made Sindhi films a decade and a half before making Pashto films, but it was actually during Zia’s period (of the so-called Islamization and terrorization) that eight out of a total of fifteen women filmmakers of Pashto films joined the silver screen, denying the social reality of the faceless women of KPK through women who are open with their emotions, gaze, and sexuality in films.

description: We introduce two new bases of the ring of polynomials and study their relations to known bases. The first basis is the quasiLascoux basis, which is simultaneously both a $K$-theoretic deformation of the quasikey basis and also a lift of the $K$-analogue of the quasiSchur basis from quasisymmetric polynomials to general polynomials. We give positive expansions of this quasiLascoux basis into the glide and Lascoux atom bases, as well as a positive expansion of the Lascoux basis into the quasiLascoux basis. As a special case, these expansions give the first proof that the $K$-analogues of quasiSchur polynomials expand positively in multifundamental quasisymmetric polynomials of T. Lam and P. Pylyavskyy. The second new basis is the kaon basis, a $K$-theoretic deformation of the fundamental particle basis. We give positive expansions of the glide and Lascoux atom bases into this kaon basis. Throughout, we explore how the relationships among these $K$-analogues mirror the relationships among their cohomological counterparts. We make several 'alternating sum' conjectures that are suggestive of Euler characteristic calculations.

description: This study focuses on quantitative analysis of the censor certificates of films issued by the Central Board of Film Censors (CBFC) Pakistan in the pre-and-post-1979 eras. It examines the excisions focusing on issues of decency, morality and social order. The study reviews literature from the west and east, focusing on states’ role in keeping peace and harmony in the country via the censorship. The excisions reflect the exploitation of the female body, sexual innuendos, rape, drugs, derogatory language, rebelliousness, and comments on friendly states. The study finds that the CBFC issues six types of certificates to films for exhibition in Pakistan as opposed to the three recommended in the Censorship of Film Rules (1980). The factor analysis reveals a simple structure showing communality between rape and aggression (alcoholism and sexuality), and indecency and rebelliousness.

description: A model for the infrared sector of Yang-Mills theory based on magnetic vortices represented by (closed) random surfaces is investigated using lattice Monte Carlo methods. The random surfaces are governed by a surface area action and a curvature action. The model generates a finite-temperature deconfinement transition; the coupling constants of the model can be chosen such as to reproduce the SU(2) Yang-Mills ratio of the deconfinement temperature to the square root of the zero-temperature string tension, T_c / sqrt{sigma_0} =0.69. This yields a physical trajectory in the space of coupling constants on which the confinement properties are approximately invariant. An at first sight surprisingly accurate prediction of the spatial string tension in the deconfined phase results, which can be made plausible in view of the specific space-time structure of the vortex configurations in this phase. The confinement properties are shown to be intimately tied to the percolation properties of the vortex surfaces.

description: The MEU GIS-enabled web-platform [1] has been developed in close collaboration with four Swiss cities. The tool enables detailed monitoring and planning for both energy demand and supply at individual building, neighborhood and whole city scale (http://meu.epfl.ch). This web-platform acts like an interface between different tools and allows to establish detailed energy balances for entire cities comprising several thousand buildings. In its present configuration, the MEU tool does not allow yet to simulate energy networks behaviors, based on the real or projected energy demand in an urban zone. In order to meet this need from energy utilities partners, a specific data model, as well as an user-interface giving access to networks attributes and edition/simulation tools were developed, which will be then functionally integrated in the MEU platform. The idea is to create a “Natural Gas Networks” module built for energy utilities. The objectives of this project within the larger MEU endeavor were the following: 1) Create a platform gathering topological and geo-referenced data; 2) Develop a gas network pre-design/planning methodology including demand characteristics and gas supply for buildings in a selected area; 3) Interface with gas distribution system operators existing tools and add new functionalities within a single platform; 4) Include natural gas distribution system operator constraints and operational realities in the pre-design/planning process. In order to achieve those objectives, two tools and several visualization concepts have been created, along with an ad hoc data model: (i) a data model able to allow data import, storage and centralization from energy utilities databases: networks, buildings demands and specifications, as well as interface between edition, simulation and visualization tools; (ii) a network edition tool prototype (LEAFLET JavaScript based web page), which allows to display a network on a map, to add/delete or drag&drop pipes, nodes, consumption and biogas production/injection points and pressure let down stations; (iii) a network flows, and pressures simulation device (MATLAB® compressible fluids model) which computes the network behavior for each hour (pressures, flows, power equivalent and temperatures in each point); (iv) a detailed mock-up for visualization and display concept with interactive and GIS data: buildings area, networks paths, pipes characteristics, results from simulation, studied area energy balance, etc. This paper focuses more specifically on the visualization and network edition tool, as well as simulation results interactive representation on the MEU platform.
Pulsar acceleration by asymmetric emission of sterile neutrinos

description: A convincing explanation for the observed pulsar large peculiar velocities is still missing. We argue that any viable particle physics solution would most likely involve the resonant production of a non-interacting neutrino $ν_s$ of mass $m_{ν_s}\sim 20$--50 keV. We propose a model where anisotropic magnetic field configurations strongly bias the resonant spin flavour precession of tau antineutrinos into $ν_s$. For internal magnetic fields $B_{int} \gsim 10^{15}$ G a $\barν_τ$-$ν_s$ transition magnetic moment of the order of $10^{-12}$ Bohr magnetons is required. The asymmetric emission of $ν_s$ from the core can produce sizeable natal kicks and account for recoil velocities of several hundred kilometers per second.

description: It has recently been noted that there seems to be a strong correlation between planetary nebulae with close binary central stars, and highly enhanced recombination line abundances. We present new deep spectra of seven objects known to have close binary central stars, and find that the heavy element abundances derived from recombination lines exceed those from collisionally excited lines by factors of 5-95, placing several of these nebulae among the most extreme known abundance discrepancies. This study nearly doubles the number of nebulae known to have a binary central star and an extreme abundance discrepancy. A statistical analysis of all nebulae with measured recombination line abundances reveals no link between central star surface chemistry and nebular abundance discrepancy, but a clear link between binarity and the abundance discrepancy, as well as an anticorrelation between abundance discrepancies and nebular electron densities: all nebulae with a binary central star with a period of less than 1.15 days have an abundance discrepancy factor exceeding 10, and an electron density less than $\sim$1000 cm$^{-3}$; those with longer period binaries have abundance discrepancy factors less than 10 and much higher electron densities. We find that [O~{\sc ii}] density diagnostic lines can be strongly enhanced by recombination excitation, while [S~{\sc ii}] lines are not. These findings give weight to the idea that extreme abundance discrepancies are caused by a nova-like eruption from the central star system, occurring soon after the common-envelope phase, which ejects material depleted in hydrogen, and enhanced in CNONe but not in third-row elements.

description: The galaxy density field as extracted from the IRAS 1.2 Jy redshift survey is compared to the mass density field as reconstructed by the POTENT method from the Mark III catalog of peculiar velocities. The reconstruction is done with Gaussian smoothing of radius 12 h^{-1}Mpc, and the comparison is carried out within volumes of effective radii 31-46 h^{-1}Mpc, containing approximately 10-26 independent samples. Random and systematic errors are estimated from multiple realizations of mock catalogs drawn from a simulation that mimics the observed density field in the local universe. The relationship between the two density fields is found to be consistent with gravitational instability theory in the mildly nonlinear regime and a linear biasing relation between galaxies and mass. We measure beta = Omega^{0.6}/b_I = 0.89 \pm 0.12 within a volume of effective radius 40 h^{-1}Mpc, where b_I is the IRAS galaxy biasing parameter at 12 h^{-1}Mpc. This result is only weakly dependent on the comparison volume, suggesting that cosmic scatter is no greater than \pm 0.1. These data are thus consistent with Omega=1 and b_I\approx 1. If b_I>0.75, as theoretical models of biasing indicate, then Omega>0.33 at 95% confidence. A comparison with other estimates of beta suggests scale-dependence in the biasing relation for IRAS galaxies.

description: This entry examines the representations of women and gender in films of Islamic Republic of Pakistan, keeping in mind the origin of romantic musicals in Natya Shastra of Bharata Muni and Parsi musical theatre. Focusing on the modest chhooi-mooi girl, a popular jutty, a folklore protagonist like Heer, and a dirty dancer, the entry highlights the modesty of the ‘ideal’ chhooi-mooi girl and defiance, tenacity, and decision power of Heer. Discussing the politics of quality and identity, the entry examines the conditions of these two women to find that the chhooi-mooi girl is a quality (a symbol of femininity) while Heer is a symbol of identity (female agency). Real Pakistani women oscillate between the conditions of these two women in their struggle to survive, love a man of their choice, or just live happily. Films reinforce the stereotypes of self-sacrificing, subservient women who either avoid or seek men’s company under the symbolic order.
Freezing of the optical--branch energy in a diatomic FPU chain

Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: We study the exchange of energy between the modes of the optical branch and those of the acoustic one in a diatomic chain of particles, with masses $m_1$ and $m_2$. We prove that, at small temperature and provided $m_1\gg m_2$, for the majority of the initial data the energy of each branch is approximately constant for times of order $β^{S/2}$, where $S=\lfloor \sqrt{m_1/m_2}/2\rfloor$ and $β$ is the inverse temperature. The result is uniform in the thermodynamic limit.

INTEGRATING SPEAKING AND LISTENING SKILLS TO IMPROVE LANGUAGE COMPREHENSION AMONG YOUNG LEARNERS
Creators: name: Gulmira Ismoilova student at Karshi State University
Publisher: name: Zenodo
Year: 2024

description:           Many teachers have a difficulty in teaching young learners because of their age and comprehension limitations, so using integrated approach can be effective for both teachers and students to improve language learning efficiency. Choosing appropriate material can increase language acquisition among youngsters and make lessons more interesting than traditional classes. Listening and speaking are the main skills to communicate and improve students’ comprehension that is why it becomes popular among teachers to combine them during the classes. This article reflects on how to improve young learners’ oral communication, make classes more energetic and increase language learning productivity when speaking and listening skills are taught in an integrated way.

description: We re-analyze data from available finite-temperature QCD simulations near the chiral transition, with the help of Chiral Random Matrix Theory (chRMT). Statistical properties of the lowest-lying eigenvalues of the staggered Dirac operator for SU(3) lattice gauge theory with dynamical fermions are examined. We consider temperatures below, near, and above the critical temperature $T_c$ for the chiral phase transition. Below and above $T_c$ the statistics are in agreement with the exact analytical predictions in the microscopic scaling regime. Above $T_c$ we observe a gap in the spectral density and a distribution compatible with the Airy distribution. Near $T_c$ the eigenvalue correlations appear inconsistent with chRMT.

description: We compute and analyse the low-lying spectrum of 2+1 dimensional $SU(N)$ Yang-Mills theory on a spatial torus of size $l\times l$ with twisted boundary conditions. This paper extends our previous work \cite{Perez:2013dra}. In that paper we studied the sector with non-vanishing electric flux and concluded that the energies only depend on the parameters through two combinations: $x=λN l /(4π)$ (with $λ$ the 't Hooft coupling) and the twist angle $\tilde θ$ defined in terms of the magnetic flux piercing the two-dimensional box. Here we made a more complete study and we are able to condense our results, obtained by non-perturbative lattice methods, into a simple expression which has important implications for the absence of tachyonic instabilities, volume independence and non-commutative field theory. Then we extend our study to the sector of vanishing electric flux. We conclude that the onset of the would-be large-volume glueball states occurs at an approximately fixed value of $x$, much before the stringy torelon states have become very massive.

The Dirac operator on hypersurfaces

Year: 1998
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Odd-dimensional Riemannian spaces that are non-orientable, but have a pin structure, require the consideration of the twisted adjoint representation of the corresponding pin group. It is shown here how the Dirac operator should be modified, also on even-dimensional spaces, to make it equivariant with respect to the action of that group when the twisted adjoint representation is used in the definition of the pin structure. An explicit description of a pin structure on a hypersurface, defined by its immersion in a Euclidean space, is used to derive a "Schroedinger" transform of the Dirac operator in that case. This is then applied to obtain - in a simple manner - the spectrum and eigenfunctions of the Dirac operator on spheres and real projective spaces.

description: Electric fields are central to the operation of optoelectronic devices based on conjugated polymers since they drive the recombination of electrons and holes to excitons in organic light-emitting diodes but are also responsible for the dissociation of excitons in solar cells. One way to track the microscopic effect of electric fields on charge carriers formed under illumination of a polymer film is to exploit the fluorescence arising from delayed recombination of carrier pairs, a process which is fundamentally spin dependent. Such spin-dependent recombination can be probed directly in fluorescence, by optically detected magnetic resonance (ODMR). Depending on the relative orientation, an electric field may either dissociate or stabilize an electron-hole carrier pair. We find that the ODMR signal in a polymer film is quenched in an electric field, but that, at fields exceeding 1 MV/cm, this quenching saturates. This finding contrasts the complete ODMR suppression that was previously observed in polymeric photodiodes, indicating that exciton-charge interactions---analogous to Auger recombination in crystalline semiconductors---may constitute the dominant carrier-pair dissociation process in organic electronics.

Heavy neutrino threshold effects in low energy phenomenology

description: Right handed neutrinos with mass of ${\cal O} \; (10^{12}-10^{13})$ GeV are required to implement the see-saw mechanism and generate neutrino masses capable of playing a role in structure formation. Moreover models of fermion masses often relate the Yukawa couplings involving these neutrinos to the up-quark Yukawa couplings. Here we study the effects of such couplings on the radiative corrections to quark masses. We find that $b-τ$ equality at $M_{GUT}$ may still give the correct $m_b/m_τ$-- ratio at low energies, but only if there is large $μ-τ$ mixing in the charged leptonic sector. We propose specific mass matrix ``textures'' dictated by a $U(1)$ family symmetry whose structure preserves $m_b=m_τ$ at $M_{GUT}$. In these schemes, due to the large $ν_μ - ν_τ$ mixing, it is possible to give a simultaneous solution to the solar neutrino deficit and the atmospheric neutrino problem.
