title: Clinical markers of developmental language disorder in Arabic
Creators: name: Taha, Juhayna
Publisher: name: University of Reading
Year: 2022

description: Data on the typical and impaired acquisition of Arabic is limited and only a few standardized Arabic language assessments are available. As a result, the identification of developmental language disorder (DLD) in Arabic is notoriously challenging. Developing new diagnostic language tools is thus imperative to facilitate early and accurate identification of DLD in Arabic-speaking children with a view to developing relevant interventions. This thesis addressed this issue by investigating potential clinical markers of DLD in Arabic through three theoretically grounded studies focusing on the linguistic and processing deficits that characterize Arabic speaking children with DLD and could be used as indicators of the presence of the disorder. Study 1 showed that the production of verb tense and subject-verb agreement is generally impaired in 5-year-old Arabic-speaking children with DLD relative to same-age peers. Study 1 showed that poor use of present tense and subject-verb feminine agreement could be potential grammatical markers of DLD in Arabic. Study 2 revealed that nonword repetition is an area of difficulty for 4 to 6-year-old Arabic-speaking children with DLD. Importantly, Study 2 found that poor nonword repetition accurately identified 93% of children with DLD and 93% of age-matched TD children, suggesting that poor nonword repetition could also be a possible clinical marker of DLD in Arabic. Study 3 reported poor sentence repetition abilities in 4 to 6- year-old Arabic-speaking children; the sentence repetition task correctly identified more than 90% of children with DLD and more than 90% of age-matched TD children. Study 3 thus suggests that poor sentence repetition may also hold promise as a potential clinical marker for the presence or absence of DLD in Arabic. The findings of this thesis could help enhance the diagnostic practices of DLD in Arabic-speaking children by focusing clinicians’ attention on relevant tasks which could aid diagnosis. The findings extend our understanding of the underlying mechanisms of DLD. Specifically, the language difficulties of Arabic-speaking children with DLD seem to reflect a combination of deficits in linguistic knowledge and processing capacity. This thesis is the first study to my knowledge to address the issue of clinical markers of DLD in Arabic and as such it paves the way and highlights the need for further research to better characterize the linguistic and non-linguistic, as well as the functional limitations in Arabic-speaking children with DLD.

description: We calculate the temperature dependence of the correlation length xi and the uniform susceptibility chi_0 of the frustrated J1-J2 square-lattice Heisenberg ferromagnet in the collinear stripe phase using Green-function technique. The height chi_{max} and the position T(chi_{max}) of the maximum in the chi_0(T) curve exhibit a characteristic dependence on the frustration parameter J2/|J1|, which is well described by power laws, chi_{max}=a(J2-J2^c)^{-nu} and T(chi_{max})=b(J_2-J_2^c), where J2^c = 0.4 and nu is of the order of unity.The correlation length diverges at low temperatures as xi \propto e^{A/T}, where A increases with growing J2/|J1|. We also compare our results with recent measurements on layered vanadium phosphates and find reasonable agreement.

description: We analyze the long-term (rest-frame 3-30 yr) X-Ray variability of eleven broad absorption line (BAL) quasars, mainly to constrain the variation properties of the X-Ray absorbing shielding gas that is thought to play a critical role in BAL wind launching. Our BAL quasar sample has coverage with multiple X-ray observatories including Chandra, XMM-Newton, BeppoSAX, ASCA, ROSAT, and Einstein; 3-11 observations are available for each source. For seven of the eleven sources we have obtained and analyzed new Chandra observations suitable for searching for any strong X-ray variability. We find highly significant X-Ray variability in three sources (PG 1001+054, PG 1004+130, and PG 2112+059). The maximum observed amplitude of the 2-8 keV variability is a factor of $3.8\pm 1.3$, $1.5\pm 0.2$, and $9.9\pm 2.3$ for PG 1001+054, PG 1004+130, and PG 2112+059, respectively, and these sources show detectable variability on rest-frame timescales down to 5.8, 1.4, and 0.5 yr. For PG 1004+130 and PG 2112+059 we also find significant X-Ray spectral variability associated with the flux variability. Considering our sample as a whole, we do not find that BAL quasars exhibit exceptional long-term X-Ray variability when compared to the quasar population in general. We do not find evidence for common strong changes in the shielding gas owing to physical rearrangement or accretion-disk rotation, although some changes are found; this has implications for modeling observed ultraviolet BAL variability. Finally, we report for the first time an X-Ray detection of the highly polarized and well-studied BAL quasar IRAS 14026+4341 in its new Chandra observation.

description: A pressure-robust space discretization of the incompressible Navier--Stokes equations in a rotating frame of reference is considered. The discretization employs divergence-free, H1-conforming mixed finite element methods like Scott--Vogelius pairs. An error estimate for the velocity is derived that tracks the dependency of the error bound on the coefficients of the problem, in particular on the angular velocity. Numerical examples illustrate the theoretical results.

description: The description of the hadron production at very forward rapidities and low transverse momentum is usually made using phenomenological models based on nonperturbative physics. However, at high energies and large rapidities the wave function of one of the projectiles is probed at very small Bjorken $x$, being characterized by a large number of gluons. In this kinematical regime, a new state of matter - the Color Glass Condensate (CGC) - is expected to be formed. One the main characteristics of such system is the presence of a new dynamical momentum scale, the saturation scale $Q_s$, which can assume values very larger than the QCD confinement scale $Λ_{QCD}$ and give the scale of the running coupling constant. In this paper we assume that in particular kinematical region probed by LHC forward (LHCf) experiment the saturation scale can be considered the hard momentum scale present in the process and calculate the forward neutral pion production at very low-$p_T$ using a perturbative approach. We demonstrate that the CGC formalism is able to successfully describe the LHCf data, which can be considered as a compelling indication of the presence of non-linear QCD effects at LHC energies.

description: Recently Hořava proposed a renormalizable quantum gravity, without the ghost problem, by abandoning Einstein's equal-footing treatment of space and time through the anisotropic scaling dimensions. Since then various interesting aspects, including the exact black hole solutions have been studied but no "rotating" black hole solutions have been found yet, except some limiting cases. In order to fill the gap, I consider a simpler three-dimensional set-up with z=2 and obtain the exact rotating black hole solution. This solution has a ring curvature singularity inside the outer horizon, like the four- dimensional Kerr black hole in Einstein gravity, as well as a curvature singularity at the origin. The usual mass bound works also here but in a modified form. Moreover, it is shown that the conventional first law of thermodynamics with the usual Hawking temperature and chemical potential does not work, which seems to be the genuine effect of Lorentz-violating gravity due to lack of the absolute horizon.

Two-photon scattering of a tightly focused weak light beam from a small atomic ensemble : an optical probe to detect atomic level structures

description: We study two-photon scattering of a tightly focused weak light beam from a small atomic ensemble of two-level atoms (2LAs). This is similar to the scattering of photons from an atomic ensemble in a one-dimensional waveguide. The scaling of two-photon nonlinearity at single-photon resonance shows a non-monotonic behaviour with an increasing number of few identical 2LAs. The two-photon nonlinearity decays monotonically with an increasing number of atoms for incident photons detuned from single-photon resonance. Single-photon transport in two 2LAs is similar to that in a single V-type three-level atom (3LA). However two-photon transport in these two systems shows very different line-shapes. When single-photon transmission is zero in these systems, two transmitted photons are bunched together in a V-type 3LA, while their correlation is zero in two 2LAs. The difference in the two-photon line-shape persists for few 2LAs and 3LAs. Therefore, the two-photon scattering of a tightly focused weak light beam can be used as a probe to detect atomic level structures of different atoms with similar transition energies.

description: We analyze the screening of a magnetic quantum dot with spin 1/2 coupled to two helical liquids. Interestingly, we find two qualitatively different sets of Toulouse points, i.e., nontrivial parameters for which we can solve the two channel Kondo model exactly. This enables us to calculate the temperature and voltage dependent Kondo screening cloud, which develops oscillations for an applied spin voltage $μ_s$. Such a spin voltage can be conveniently applied by a charge bias in a four-terminal helical liquid setup.

description: In the paper untitled "Laplace equations and the Weak Lefschetz Property" the authors highlight the link between rational varieties satisfying a Laplace equation and artinian ideals that fail the Weak Lefschetz property. Continuing their work we extend this link to the more general situation of artinian ideals failing the Strong Lefschetz Property. We characterize the failure of SLP (that includes WLP) by the existence of special singular hypersurfaces (cones for WLP). This characterization allows us to solve three problems posed by Migliore and Nagel and to give new examples of ideals failing the SLP. Finally, line arrangements are related to artinian ideals and the unstability of the associated derivation bundle is linked with the failure of SLP. Moreover we reformulate the so-called Terao's conjecture for free line arrangements in terms of artinian ideals failing the SLP.

description: We report the results of an experiment investigating coherence and correlation effects in a system of coupled donors. Two donors are strongly coupled to two leads in a parallel configuration within a nano-wire field effect transistor. By applying a magnetic field we observe interference between two donor-induced Kondo channels, which depends on the Aharonov-Bohm phase picked up by electrons traversing the structure. This results in a non-monotonic conductance as a function of magnetic field and clearly demonstrates that donors can be coupled through a many-body state in a coherent manner. We present a model which shows good qualitative agreement with our data. The presented results add to the general understanding of interference effects in a donor-based correlated system which may allow to create artificial lattices that exhibit exotic many-body excitations.

description: During the calibration phase of the photomultiplier tubes (PMT) for the Double Chooz experiment the PMT response to light with single photoelectron (SPE) intensity was analysed. With our setup we were able to measure the combined transit time and charge response of the PMT and therefore we could deconstruct and analyse all physical effects having an influence on the PMT signal. Based on this analysis charge and time correlated probability density functions were developed to include the PMT response in a Monte Carlo simulation.

The role of $f_0(1710)$ in the $ϕω$ threshold peak of $J/Ψ\to γϕω$

description: We study the process $J/Ψ\to γϕω$, measured by the BES experiment, where a neat peak close to the $ϕω$ threshold is observed and is associated to a scalar meson resonance around 1800 MeV. We make the observation that a scalar resonance coupling to $ϕω$ unavoidably couples strongly to $K \bar K$, but no trace of a peak is seen in the $K \bar K$ spectrum of the $J/Ψ\to γK \bar K$ at this energy. This serves us to rule out the interpretation of the observed peak as a signal of a new resonance. After this is done, a thorough study is performed on the production of a pair of vector mesons and how its interaction leads necessarily to a peak in the $J/Ψ\to γϕω$ reaction close to the $ϕω$ threshold, due to the dynamical generation of the $f_0(1710)$ resonance by the vector-vector interaction. We then show that both the shape obtained for the $ϕω$ mass distribution, as well as the strength are naturally reproduced by this mechanism. The work also explains why the $ϕω$ peak is observed in the BES experiment and not in other reactions, like $B^\pm\to K^\pm ϕω$ of Belle.

description: We numerically investigate Lyapunov instabilities for one-, two- and three-dimensional lattices of interacting classical spins at infinite temperature. We obtain the largest Lyapunov exponents for a very large variety of nearest-neighbor spin-spin interactions and complete Lyapunov spectra in a few selected cases. We investigate the dependence of the largest Lyapunov exponents and whole Lyapunov spectra on the lattice size and find that both quickly become size-independent. Finally, we analyze the dependence of the largest Lyapunov exponents on the anisotropy of spin-spin interaction with the particular focus on the difference between bipartite and nonbipartite lattices.

description: The unoccupied states of complex materials are difficult to measure, yet play a key role in determining their properties. We propose a technique that can measure the unoccupied states, called time-resolved Compton scattering, which measures the time-dependent momentum distribution (TDMD). Using a non-equilibrium Keldysh formalism, we study the TDMD for electrons coupled to a lattice in a pump-probe setup. We find a direct relation between temporal oscillations in the TDMD and the dispersion of the underlying unoccupied states, suggesting that both can be measured by time-resolved Compton scattering. We demonstrate the experimental feasibility by applying the method to a model of MgB$_2$ with realistic material parameters.

description: According to standard liquid-state theory repulsive and attractive pair forces play distinct roles for the physics of liquids. This paradigm is put into perspective here by demonstrating a continuous series of pair potentials that have virtually the same structure and dynamics, although only some of them have attractive forces of significance. Our findings reflect the fact that the motion of a given particle is determined by the total force on it, whereas the quantity usually discussed in liquid-state theory is the individual pair force.

description: A saúde bucal dos pacientes em unidade de terapia intensiva (UTI) deve ser uma preocupação dos profissionais de saúde, visto que muitas infecções da cavidade oral podem levar o paciente a complicações do quadro clínico. Objetivo do presente trabalho foi verificar os fatores relacionados à condição de saúde bucal que podem influenciar na evolução do quadro clínico dos pacientes internados em UTIs. Para isso, foi realizada uma revisão integrativa de literatura, utilizando periódicos retirados das bases de dados PubMED, SciELO, Cochrane, Google Acadêmico e livros base, no período compreendido entre 1972 e 2023. Os resultados indicaram que pessoas internadas em UTIs, especialmente os dependentes de suporte respiratório, apresentam higiene bucal deficiente, o que predispõe ao acúmulo de biofilmes bacterianos, que podem agravar quadros de pneumonias e outras infecções nosocomiais, em especial a pneumonia associada à ventilação mecânica (PAV). Infecções orais prévias, como doenças periodontais, também contribuem com a instalação das PAVs. Esses dados foram bem documentados com o aumento dos pacientes que necessitaram de suporte respiratório durante a pandemia de COVID-19 (entre 2019 e 2022). Os resultados obtidos reforçam a importância da equipe multidisciplinar nas UTIs, evidenciando a necessidade de cirurgiões dentistas em tais unidades, pois diante de inúmeros problemas advindos da condição de saúde bucal em pessoas internadas, a presença de profissionais apropriados para a manutenção da saúde bucal se torna indispensável.
Compressed Sensing Signal Recovery via Forward-Backward Pursuit

description: Recovery of sparse signals from compressed measurements constitutes an l0 norm minimization problem, which is unpractical to solve. A number of sparse recovery approaches have appeared in the literature, including l1 minimization techniques, greedy pursuit algorithms, Bayesian methods and nonconvex optimization techniques among others. This manuscript introduces a novel two stage greedy approach, called the Forward-Backward Pursuit (FBP). FBP is an iterative approach where each iteration consists of consecutive forward and backward stages. The forward step first expands the support estimate by the forward step size, while the following backward step shrinks it by the backward step size. The forward step size is larger than the backward step size, hence the initially empty support estimate is expanded at the end of each iteration. Forward and backward steps are iterated until the residual power of the observation vector falls below a threshold. This structure of FBP does not necessitate the sparsity level to be known a priori in contrast to the Subspace Pursuit or Compressive Sampling Matching Pursuit algorithms. FBP recovery performance is demonstrated via simulations including recovery of random sparse signals with different nonzero coefficient distributions in noisy and noise-free scenarios in addition to the recovery of a sparse image.

description: We demonstrate the asymptotic real second order freeness of Haar distributed orthogonal matrices and an independent ensemble of random matrices. Our main result states that if we have two independent ensembles of random matrices with a real second order limit distribution and one of them is invariant under conjugation by an orthogonal matrix, then the two ensembles are asymptotically real second order free. This captures the known examples of asymptotic real second order freeness introduced by Redelmeier [R1, R2].

description: In this work, we find by means of first principle calculations a new physical mechanism to generate a two dimensional electron gas, namely, the breaking of charge ordering at the surface of a charge ordered semiconductor due to the incomplete oxygen environment of the surface ions. The emergence of the 2D gas is independent of the presence of oxygen vacancies or polar discontinuities; this is a self-doping effect. This mechanism might apply to many charge ordered systems, in particular, we study the case of BaBiO3(001). In bulk, this material is a prototype of a "forbidden valence" compound in which the formal "metallic" Bi4+ state is skipped exhibiting a charge disproportionated Bi3+ - Bi5+ ordered structure. At room temperature, this charge disproportionation together with the breathing distortions gives rise to a Peierls semiconductor with monoclinic crystal structure. At higher temperature (T > 750 K) or upon doping, it turns cubic and metallic. Interestingly, doped BaBiO3 was one of the first non-cuprate high-Tc superconductors discovered. The outer layer of the Bi-terminated simulated surface turns more cubic- like and metallic while the inner layers remain in the insulating monoclinic state. On the other hand, the metallization does not occur for the Ba termination, a fact that makes this system appealing for nanostructuring. Finally, this finding sets another possible route for future exploration: the potential scenario of 2D superconductivity at the BaBiO3 surface.

description: In this paper we describe the unramified Langlands correspondence for two-dimensional local fields, we construct a categorical analogue of the unramified principal series representations and study its properties. The main tool for this description is the construction of a central extension. For this (and other) central extension we prove noncommutative reciprocity laws (i.e. the splitting of the central extensions over some subgroups) for arithmetic surfaces and projective surfaces over a finite field. These reciprocity laws connect central extensions which are constructed locally and globally.

Simple and direct communication of dynamical supersymmetry breaking

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We present a complete, calculable, and phenomenologically viable model of dynamical supersymmetry breaking. The model is a simple extension of the so called 3-2 model, with gauge group SU(3)xSU(2)xG_SM and the MSSM fields directly coupled to the hidden sector SU(2) vector fields. Sfermion masses are universal, thus solving the supersymmetric flavour problem, and gaugino masses are not suppressed, in fact they are predicted to be of the same order as sfermion masses. Sizeable contributions to the MSSM A-terms can be generated, depending on the size of some free couplings. As a byproduct, we show some properties of a class of models with n pairs of Higgs doublets.

description: The predictions for the Higgs mass in extensions of the Minimal Supersymmetric Standard Model are discussed. We propose a simple theory where the Higgs mass is modified at tree-level and one can achieve a mass around 125 GeV without assuming heavy stops or large left-right mixing in the stop sector. All the parameters in the theory can be perturbative up to the grand unified scale, and one predicts the existence of new colored fields at the TeV scale. We refer to this model as Adjoint MSSM. We discuss the main phenomenological aspects of this scenario and the possible signatures at the Large Hadron Collider.

Subjects: modèle ARDL, prix, production, balance commerciale.

description: L'économie d'un pays est étroitement liée à la demande de biens et de services, qui est fortement influencée par les variations des prix et des niveaux de production. Ces facteurs affectent directement les importations, qui sont essentielles à l'équilibre du déficit intérieur. Par conséquent, le solde commercial peut fluctuer entre des variations positives et négatives, reflétant la réactivité de l'économie aux variations de ces paramètres.
Cette étude se distingue par sa méthodologie empirique, qui utilise le modèle ARDL pour évaluer l'impact du prix sur la balance commerciale du Maroc. De plus, elle incorpore d'autres variables cruciales telles que le taux de change nominal et la production céréalière. Les résultats obtenus mettent en évidence des relations significatives à court et à long terme entre ces facteurs et le solde commercial (BC).
Cette recherche apporte un éclairage précieux sur les mécanismes qui sous-tendent l'évolution de la balance commerciale du Maroc. Elle souligne à quel point ces paramètres sont essentiels à la compréhension et à la gestion de la dynamique économique du pays.
Classical Light Sources with Tunable Temporal Coherence and Tailored Photon Number Distributions

description: We demonstrate the generation of classical incoherent light with electronic control over its temporal characteristics and photon number distribution. The tunability of the temporal coherence is shown, under both classical and quantum detection, through second order correlation ($G^2(τ)$) measurements. The tailoring of desired classical photon number distributions is illustrated by creating two representative light sources - one thermal and the other a specific classical, non-Gaussian state. Such generation of classical light sources, quite different from existing natural light sources, is likely to be a useful resource in quantum information processing. As a particular application in this direction we outline how a non-Gaussian state generated in this manner may be mixed with an appropriate non-classical Gaussian state at a beamsplitter, to generate non-Gaussian entanglement.

A uniform treatment of the orbital effects due to a violation of the Strong Equivalence Principle in the gravitational Stark-like limit

description: We analytically work out several effects which a violation of the Strong Equivalence Principle (SEP) induces on the orbital motion of a binary system constituted of self-gravitating bodies immersed in a constant and uniform external field. We do not restrict to the small eccentricity limit. Moreover, we do not select any specific spatial orientation of the external polarizing field. We explicitly calculate the SEP-induced mean rates of change of all the osculating Keplerian orbital elements of the binary, the perturbation of the projection of the binary orbit onto the line-of-sight, the shift of the radial velocity, and the range and range-rate signatures and as well. We find that the ratio of the SEP precessions of the node and the inclination of the binary depends only on and the pericenter of the binary itself, being independent on both the magnitude and the orientation of the polarizing field, and on the semimajor axis, the eccentricity and the node of the binary. Our results, which do not depend on any particular SEP-violating theoretical scheme, can be applied to quite general astronomical and astrophysical scenarios. They can be used to better interpret present and future SEP experiments, especially when several theoretical SEP mechanisms may be involved, and to suitably design new dedicated tests.

description: For neutrino mixing we propose to use the parameter set $X_{i}$ $(=|V_{ei}|^{2})$ and $Ω_{i}$ $(=ε_{ijk}|V_{μj}|^{2}|V_{τk}|^{2})$, with two constraints. These parameters are directly measurable since the neutrino oscillation probabilities are quadratic functions of them. Physically, the set $Ω_{i}$ signifies a quantitative measure of $μ-τ$ asymmetry. Available neutrino data indicate that all the $Ω_{i}$'s are small $(\lesssim O(10^{-1}))$, but with large uncertainties. The behavior of $Ω_{i}$ as functions of the induced neutrino mass in matter are found to be simple, which should facilitate the analyses of long baseline experiments.

description: Crickets are being reevaluated as food and livestock feed due to their high nutritional value and low environmental impact during production, as food waste can be used as feed. On the other hand, current cricket production uses feed used in aquaculture and poultry farming, and these feeds contain animal proteins such as fish meal and chicken meal. This is simply converting other animal proteins into insect proteins. Therefore, this study aimed to test whether two-spotted cricket powder can be used as a substitute for fishmeal in diets for Gryllus bimaculatus production. Cricket weight, feed efficiency, and number of crickets were evaluated by feeding rice bran: cricket powder = 85:15 and rice bran: fish meal = 85:15, respectively, referring to the feed mix ratio used by cricket producers. Results showed no statistically significant differences between the two experiments in cricket weight and feed conversion ratio. When data were obtained separately for each growth phase, cricket weight was found to be highest in the fourth post-hatching week for the diet with cricket powder and then decreased (initial input: 1 g; 28 days: 89.45 ± 22.19 g; 35 days: 49.47 ± 14.11 g). Feed conversion efficiency was found to be higher in the second half of growth (1-7 days: 0.48; 23-28 days: 0.80). The use of insect powder as bait for crickets is a new proposal. In cricket production, adults with low reproductive capacity are packaged and sold as food or livestock feed, but by using insect powder as feed during cricket production, it is possible to reduce animal protein in the feed. In the future, we plan to investigate the usefulness of mass-produced insect powder as feed for crickets.

description: We study multi-field DBI inflation models with a waterfall phase transition. This transition happens for a D3 brane moving in the warped conifold if there is an instability along angular directions. The transition converts the angular perturbations into the curvature perturbation. Thanks to this conversion, multi-field models can evade the stringent constraints that strongly disfavour single field ultra-violet DBI inflation models in string theory. We explicitly demonstrate that our model satisfies current observational constraints on the spectral index and equilateral non-Gaussianity as well as the bound on the tensor to scalar ratio imposed in string theory models. In addition we show that large local type non-Gaussianity is generated together with equilateral non-Gaussianity in this model.
