description: Intermediate mass galaxies (logM(Msun)>10) at z~0.6 are the likeliest progenitors of the present-day numerous population of spirals. There is growing evidence that they have evolved rapidly since the last 6 to 8 Gyr ago, and likely have formed a significant fraction of their stellar mass, often showing perturbed morphologies and kinematics. We have gathered a representative sample of 88 such galaxies and have provided robust estimates of their gas phase metallicity. For doing so, we have used moderate spectral resolution spectroscopy at VLT/FORS2 with unprecedented high S/N allowing to remove biases coming from interstellar absorption lines and extinction to establish robust values of R23=([OII]3727 + [OIII]4959,5007)/Hbeta. We definitively confirm that the predominant population of z~0.6 starbursts and luminous IR galaxies (LIRGs) are on average, two times less metal rich than the local galaxies at a given stellar mass. We do find that the metal abundance of the gaseous phase of galaxies is evolving linearly with time, from z=1 to z=0 and after comparing with other studies, from z=3 to z=0. Combining our results with the reported evolution of the Tully Fisher relation, we do find that such an evolution requires that ~30% of the stellar mass of local galaxies have been formed through an external supply of gas, thus excluding the close box model. Distant starbursts & LIRGs have properties (metal abundance, star formation efficiency & morphologies) similar to those of local LIRGs. Their underlying physics is likely dominated by gas infall probably through merging or interactions. Our study further supports the rapid evolution of z~0.4-1 galaxies. Gas exchanges between galaxies is likely the main cause of this evolution.

description: Recently Verlinde has suggested a new approach to gravity which interprets gravitational interaction as a kind of entropic force. The new approach uses the holographic principle by stating that the information is kept on the holographic screens which coincide with equipotential surfaces. Motivated by this new interpretation of gravity (but not being limited by it) we study equipotential surfaces, the Unruh-Verlinde temperature, energy and acceleration for various static space-times: generic spherically symmetric solutions, axially symmetric black holes immersed in a magnetic field, traversable spherically symmetric wormholes of an arbitrary shape function, system of two and more extremely charged black holes in equilibrium. In particular, we have shown that the Unruh-Verlinde temperature of the holographic screen reaches absolute zero on the wormhole throat independently of the particular form of the wormhole solution.

description: At many universities, astronomy is a popular way for non-science majors to fulfill a general education requirement. Because general-education astronomy may be the only college-level science course taken by these students, it is the last chance to shape the science attitudes of these future journalists, teachers, politicians, and voters. I report on an attempt to measure and induce changes in science attitudes in my general-education astronomy course. I describe construction of the attitude survey, classroom activities designed to influence attitudes, and give numerical results indicating a significant improvement. In contrast, the literature on attitudes in introductory physics courses generally reports stagnation or decline. I briefly comment on some plausible explanations for this difference.

description: Despite the clear and obvious need for adults to be proficient in numeracy, international studies suggest that many continue to struggle in this area. In Ireland, one of the main challenges continues to be the availability of effective adult numeracy education. This is a diverse sector, and little is known about the varied provision of adult numeracy courses and of those who teach on them. Recent research has highlighted an unmet demand for the professional development of adult numeracy practitioners with many looking for opportunities to network and further develop their practice. This study aimed to design, implement and evaluate a professional development model that supported adult numeracy practitioners in developing the necessary skills to support their students. After an initial needs analysis, a series of six ‘Numeracy-Meets’ were designed and implemented between February and May 2022. There was an average of twenty adult numeracy practitioners in attendance at each Numeracy-Meet. After all the Numeracy-Meets had taken place, five practitioners took part in individual semi-structured interviews to evaluate their experiences. This paper details the design, implementation and evaluation of these Numeracy-Meets and discusses whether they are a sustainable model of professional development for adult numeracy practitioners.

description: We present a theoretical study of the BEC-BCS crossover in the Bose-Einstein-Condensate regime (BEC), in the case of an unequal number of fermions of two species. We take full account of the composite nature of the dimers made of fermions. In the limit of low densities, we calculate the ground state energy of the system, or equivalentely the chemical potentials of each species as well as the one-particle gap and the energy of an "impurity" immersed in a Fermi sea. For the chemical potentials we go up to order (density)^{4/3}.The results found involve the exact atom-dimer a_{AD} and dimer-dimer a_{DD} scattering lengths and therefore include the 3 and 4-body problems in the manybody problem. We briefly comment on the importance of the different mean-field corrections for recent experiments.

Measurement of relative transition probabilities in argon using the Faraday effect
Creators: name: Stockmayer, Philip Henry
Publisher: name: University of British Columbia
Year: 2011

description: Relative transition probabilities for some spectral lines connecting the 4s and 4p states of neutral argon have been determined by a relatively new technique developed by Seka and Curzon involving the Faraday effect. In this method a given spectral line emitted by an argon discharge tube is plane polarized and then passed through an absorption tube embedded in an axial magnetic field. The rotation of the plane of polarization, and the intensity of the source line are measured and from the results the absorption coefficient for that particular line in the plasma is deduced. The theory used agrees excellently with the observed rotations for field values from 0 to 2600 gauss. This technique is particularly suited to strong transitions which are difficult to measure by other methods. The values obtained here for the transition probabilities are quite accurate (errors < 10%) and agree well with values given by Weise in a recent compilation. For the analysis of the Faraday rotation it was necessary to determine the effect of the magnetic field on the number density of lower excited states in the absorbing plasma. This was done using a relative absorption technique, the results of which show a linear decrease in the number densities in the first 2000 gauss.

description: Numerical range of a Hermitian operator X is defined as the set of all possible expectation values of this observable among a normalized quantum state. We analyze a modification of this definition in which the expectation value is taken among a certain subset of the set of all quantum states. One considers for instance the set of real states, the set of product states, separable states, or the set of maximally entangled states. We show exemplary applications of these algebraic tools in the theory of quantum information: analysis of k-positive maps and entanglement witnesses, as well as study of the minimal output entropy of a quantum channel. Product numerical range of a unitary operator is used to solve the problem of local distinguishability of a family of two unitary gates.

Halo stochasticity in global clustering analysis

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In the present work we study the statistics of haloes, which in the halo model determines the distribution of galaxies. Haloes are known to be biased tracer of dark matter, and at large scales it is usually assumed there is no intrinsic stochasticity between the two fields. Following the work of Seljak & Warren (2004), we explore how correct this assumption is and, moving a step further, we try to qualify the nature of stochasticity. We use Principal Component Analysis applied to the outputs of a cosmological N-body simulation to: (1) explore the behaviour of stochasticity in the correlation between haloes of different masses; (2) explore the behaviour of stochasticity in the correlation between haloes and dark matter. We show results obtained using a catalogue with 2.1 million haloes, from a PMFAST simulation with box size of 1000h^{-1}Mpc. In the relation between different populations of haloes we find that stochasticity is not-negligible even at large scales. In agreement with the conclusions of Tegmark & Bromley (1999) who studied the correlations of different galaxy populations, we found that the shot-noise subtracted stochasticity is qualitatively different from `enhanced' shot noise and, specifically, it is dominated by a single stochastic eigenvalue. We call this the `minimally stochastic' scenario, as opposed to shot noise which is `maximally stochastic'. In the correlation between haloes and dark matter, we find that stochasticity is minimized, as expected, near the dark matter peak (k ~ 0.02 h Mpc^{-1} for a LambdaCDM cosmology) and, even at large scales, it is of the order of 15 per cent above the shot noise. Moreover, we find that the reconstruction of the dark matter distribution is improved when we use eigenvectors as tracers of the bias. [Abridged]

description: We employ an old field theory model, formulated and discussed by Born, Infeld, Hoffman and Rosen during 1930s. Our method of cutting-gluing of spacetimes resolves the double-valuedness in the displacement vector D(E), pointed out by these authors. A characteristic feature of their model is to contain a logarithmic term, and by bringing forth such a Lagrangian anew, we aim to attract the interest of field theorists to such a Lagrangian. We adopt the Hoffman-Born-Infeld (HBI) Lagrangian in general relativity to construct black holes and investigate the possibility of viable thin-shell wormholes. In particular, the stability of thin-shell wormholes supported by normal matter in 5-dimensional Einstein-HBI-Gauss-Bonnet gravity is highlighted.

description: The Dirac oscillator coupled to an external two-component field can retain its solvability, if couplings are appropriately chosen. This provides a new class of integrable systems. A simplified way of solution is given, by recasting the known solution of the Dirac oscillator into matrix form; there one notices, that a block-diagonal form arises in a Hamiltonian formulation. The blocks are two-dimensional. Choosing couplings that do not affect the block structure, these just blow up the $2 \times 2$ matrices to $4 \times 4 $ matrices, thus conserving solvability. The result can be cast again in covariant form. By way of example we apply this exact solution to calculate the evolution of entanglement.

The absolute cross section for the reaction D(p,a)3 He from 400 Kev to 100 Kev
Creators: name: Helmer, Richard Lloyd
Publisher: name: University of British Columbia
Year: 2011

description: The absolute cross section of the reaction D(p,ɣ)³He has been measured in the energy range from 400 Kev to 1100 Kev in the laboratory system. A target of deuterated polyethylene was used to measure the relative yield of the reaction over this range, and the results were normalized to an absolute measurement made with a deuterium gas target. The reaction is of interest because it enables some information to be obtained about the forces binding three nucleons together. It also has some significance in a number of astrophysical processes. In order to determine the cross section, the intrinsic efficiency of a 5 inch by 4 inch sodium iodide crystal scintillation counter was measured by simultaneous alpha particle and gamma ray counting on the 340 Kev resonance of the reaction ¹⁹F(p,[symbol omitted]ɣ)¹⁶0. The intrinsic efficiency of the detector was found to be .679 ± .03 for the 6.14 Mev gamma rays from this reaction, with the particular geometry used. The absolute cross section for the reaction D(p ɣ)³He was found by the gas target measurement to be 2.33 ± .07 microbarns for an incident proton energy of 643 kev.
Hadronic Production of Gamma Rays and Starburst Galaxies

description: The Milky Way has been estabished to emit gamma rays. These gamma rays are presumably dominated by decays of neutral pions, although inverse Compton scatterings and bremsstrahlung also contribute. It is plausible that other galaxies can be diffuse sources of gamma rays in a similar manner. Starburst galaxies are particularly interesting to study as they are expected to have much higher cosmic-ray fluxes and interstellar matter densities. The neutral pions are created in cosmic-ray interactions with interstellar matter. Presented here is an overview of the recent work by Karlsson and co-workers on proton-proton interactions and the resulting secondary particle inclusive cross sections and angular distributions. This model can be used to calculated the $π^{0}$ component of the gamma-ray yield and spectrum from a starburst galaxy. The yield is expected to increase significantly (30% to 50%) and the spectrum to be harder than the incident proton spectrum.

description: The geometric approach to study the dynamics of U(1)-invariant membranes is developed. The approach reveals an important role of the Abel nonlinear differential equation of the first type with variable coefficients depending on time and one of the membrane extendedness parameters. The general solution of the Abel equation is constructed. Exact solutions of the whole system of membrane equations in the D=5 Minkowski space-time are found and classified. It is shown that if the radial component of the membrane world vector is only time dependent then the dynamics is described by the pendulum equation.

Study of self-supporting deuterated polyethylene targets
Creators: name: Makosky, Lyle M.
Publisher: name: University of British Columbia
Year: 2011

description: Thin self-supporting deuterated polyethylene targets for use with the reaction 2ʜ(3ʜe,p)⁴He have been investigated. Both pouring and evaporating techniques for the construction of the polyethylene film were tested. Stable targets, capable of withstanding 690 keV ³He beam current densities of more than 10 μA/cm², were constructed by evaporating 10 μg/cm² thick carbon layers onto both sides of the (C₂D₄)n film ("sandwich" targets). Targets prepared by the pouring technique were found to be mechanically stronger than the "sandwich" targets prepared by evaporation of (C₂D₄)n. The targets exhibit an initial rapid decrease in the deuterium content during the first 150 μc of ³He beam on the target. This effect is attributed to breakdown of the C₂D₄ molecules into their atomic constituents and subsequent diffusion of the deuterium out of the target. After this initial effect, the targets deteriorate by less than 0.05% per μc. The targets were developed for use for total proton reaction cross section measurements by the associated particle technique. The beam profiles of the 15.8 MeV protons from the reaction ²H (³He,p)⁴He, which are relevant to this technique, were measured. The amount of elastic scattering suffered by the protons in the present targets was smaller than that observed with the copper backed heavy ice targets used in previous cross section measurements (Ho 68). The deuterium content of the target was found to be a linear function of the thickness of the carbon layers comprising the target "sandwich". The alpha yield from the reaction ²H (³He,p)⁴He increased by a factor of 1.83 ± 0.35 per 10 μg/cm² carbon layer on the "back" of the target, and by a factor of 1.38 ± 0.26 per 10 μg/cm2 carbon layer on the "front" of the target. As a possible explanation of this effect it is proposed that deuterium, repleased from the polyethylene by the beam, diffuses throughout the target and is trapped by the carbon to a concentration of 0.11 deuterium atoms per carbon atom.

description: A bivariate distribution with continuous margins can be uniquely decomposed via a copula and its marginal distributions. We consider the problem of estimating the copula function and adopt a Bayesian approach. On the space of copula functions, we construct a finite-dimensional approximation subspace that is parametrized by a doubly stochastic matrix. A major problem here is the selection of a prior distribution on the space of doubly stochastic matrices also known as the Birkhoff polytope. The main contributions of this paper are the derivation of a simple formula for the Jeffreys prior and showing that it is proper. It is known in the literature that for a complex problem like the one treated here, the above results are difficult to obtain. The Bayes estimator resulting from the Jeffreys prior is then evaluated numerically via Markov chain Monte Carlo methodology. A rather extensive simulation experiment is carried out. In many cases, the results favour the Bayes estimator over frequentist estimators such as the standard kernel estimator and Deheuvels' estimator in terms of mean integrated squared error.

This solves some bugs in the current Agda implementation, with no large effect on performance and a limited amount of changes to the code of Agda.

description: We study the power of quantum channels with little or no capacity for private communication. Because privacy is a necessary condition for quantum communication, one might expect that such channels would be of little use for transmitting quantum states. Nevertheless, we find strong evidence that there are pairs of such channels that, when used together, can transmit far more quantum information than the sum of their individual private capacities. Because quantum transmissions are necessarily private, this would imply a large violation of additivity for the private capacity. Specifically, we present channels which display either (1) A large joint quantum capacity but very small individual private capacities or (2) a severe violation of additivity for the Holevo information.

Thermal conductivity of inert gas solids
Creators: name: Hurst, Michael James
Publisher: name: University of British Columbia
Year: 2011

description: The thermal conductivity of perfect infinite crystals of neon, argon, krypton, and xenon has been calculated numerically. It was assumed that the crystals possessed face centred cubic structure with the atoms interacting in pairs through a Lennard-Jones 12:6 potential energy function. The calculations considered only the effects of three-phonon interactions. It was possible to simplify the calculations by introducing "reduced" physical quantities. The thermal conductivity of each of the inert gas solids considered was obtained from the "reduced thermal conductivity" which was calculated for argon. Agreement with experimental data for neon, argon, and krypton was obtained for temperatures higher than those for which the effects of crystal size and lattice defects determine the thermal conductivity. This agreement suggests that for sufficiently high temperatures the thermal conductivity is determined by the effects of three-phonon Umklapp processes.

description: Let (M,ω) be a symplectic manifold, and Sigma a compact Riemann surface. We define a 2-form on the space of immersed symplectic surfaces in M, and show that the form is closed and non-degenerate, up to reparametrizations. Then we give conditions on a compatible almost complex structure J on (M,ω) that ensure that the restriction of the form to the moduli space of simple immersed J-holomorphic Sigma-curves in a homology class A in H_2(M,\Z) is a symplectic form, and show applications and examples. In particular, we deduce sufficient conditions for the existence of J-holomorphic Sigma-curves in a given homology class for a generic J.

description: Three new compounds, including 6-methoxy-3,4,5,7-tetramethylisochromane-3,8-diol (1), 3,4,5,7-tetramethylisochromane-3,6,8-triol (2), streptimidone derivative (3), along with ten known compounds (4-13) were isolated from the Streptomyces morookaensis strain Sm4-1986. Their chemical structures were established based on the information from UV, IR, NMR (1H NMR, 13C NMR, 1H-1H COSY, HSQC, HMBC, NOESY), and mass spectroscopic. Moreover, all the isolated new compounds were evaluated for antibacterial activities (S. aureus, B. cereus, S. epidermids and methicillin-resistant S. aureus) and their cytotoxicities against MCF-7, A549, Hela tumor cell lines and Marc-145 normal cell line.
ESR study of antimony doped cadmium sulphide
Creators: name: Halliwell, Robin Ernest
Publisher: name: University of British Columbia
Year: 2011

description: The electronic g-tensor in antimony doped cadmium sulphide has been measured at 1.1°K. A sample doped to a room temperature resistivity of 3.3 ohm-cm exhibited an anisotropic g-tensor with g// = 1.788 and g⊥ = 1.770. A single asymmetric line was observed. The asymmetry of this line was found to decrease with decreasing incident power. Further experiments to study this line shape are indicated.
Impact of mergers on LISA parameter estimation for nonspinning black hole binaries

description: We investigate the precision with which the parameters describing the characteristics and location of nonspinning black hole binaries can be measured with the Laser Interferometer Space Antenna (LISA). By using complete waveforms including the inspiral, merger and ringdown portions of the signals, we find that LISA will have far greater precision than previous estimates for nonspinning mergers that ignored the merger and ringdown. Our analysis covers nonspinning waveforms with moderate mass ratios, q >= 1/10, and total masses 10^5 < M/M_{Sun} < 10^7. We compare the parameter uncertainties using the Fisher matrix formalism, and establish the significance of mass asymmetry and higher-order content to the predicted parameter uncertainties resulting from inclusion of the merger. In real-time observations, the later parts of the signal lead to significant improvements in sky-position precision in the last hours and even the final minutes of observation. For comparable mass systems with total mass M/M_{Sun} = ~10^6, we find that the increased precision resulting from including the merger is comparable to the increase in signal-to-noise ratio. For the most precise systems under investigation, half can be localized to within O(10 arcmin), and 10% can be localized to within O(1 arcmin).

description: The contribution discusses a possible relationship between some aspects of the ethical and philosophical background of Esperanto – the international language created by L.L. Zamenhof – and the religious framework established by ancient Egyptian pharaoh Akhenaten. This connection may have been made possible by Zamenhof’s affinity with Freemasonry, which notoriously grounded on ancient Egyptian concepts.

description: This contribution aims to discuss some passages by the philosopher Abū Naṣr al-Fārābī concerning the function of the so-called separated pronoun in nominal predicate sentences in Arabic. Through a comparative approach in his Kitāb al-ḥurūf between Arabic, Greek and Persian, al-Fārābī gives an original interpretation of the role of this pronoun in Arabic, markedly different from that given by Arab grammarians.

Evolution of the Dark Matter Phase-Space Density Distributions of LCDM Halos

description: We study the evolution of phase-space density during the hierarchical structure formation of LCDM halos. We compute both a spherically-averaged surrogate for phase-space density (Q) and the coarse-grained distribution function f(x,v) for dark matter particles that lie within~2 virial radii of four Milky-Way-sized dark matter halos. The estimated f(x,v) spans over four decades at any radius. Dark matter particles that end up within two virial radii of a Milky-Way-sized DM halo at $z=0$ have an approximately Gaussian distribution in log(f) at early redshifts, but the distribution becomes increasingly skewed at lower redshifts. The value corresponding to the peak of the Gaussian decreases as the evolution progresses and is well described by a power-law in (1+z). The highest values of f are found at the centers of dark matter halos and subhalos, where f can be an order of magnitude higher than in the center of the main halo. The power-law Q(r) profile likely reflects the distribution of entropy (K = sigma^2/rho^{2/3} \propto r^{1.2}), which dark matter acquires as it is accreted onto a growing halo. The estimated f(x, v), on the other hand, exhibits a more complicated behavior. Although the median coarse-grained phase-space density profile F(r) can be approximated by a power-law in the inner regions of halos and at larger radii the profile flattens significantly. This is because phase-space density averaged on small scales is sensitive to the high-f material associated with surviving subhalos, as well as relatively unmixed material (probably in streams) resulting from disrupted subhalos, which contribute a sizable fraction of matter at large radii.

description: This article is part of a broader research on sounds (aṣwāt, sing. ṣawt) as they were systematised in the context of early Arabic lexicography. It takes as a case study the multi-thematic lexicon al-Ġarīb al-Muṣannaf by Abū ‘Ubayd al-Qāsim b. Sallām (d. 224/838) and more specifically the three chapters respectively devoted to voices, tones of voices of people’s speech and their modulation, and languages and words included within the opening book regarding the lexicon on human anatomy.

description: We give a detailed description of the Veldkamp space of the smallest slim dense near hexagon. This space is isomorphic to PG(7, 2) and its 2^8 - 1 = 255 Veldkamp points (that is, geometric hyperplanes of the near hexagon) fall into five distinct classes, each of which is uniquely characterized by the number of points/lines as well as by a sequence of the cardinalities of points of given orders and/or that of (grid-)quads of given types. For each type we also give its weight, stabilizer group within the full automorphism group of the near hexagon and the total number of copies. The totality of (255 choose 2)/3 = 10795 Veldkamp lines split into 41 different types. We give a complete classification of them in terms of the properties of their cores (i. e., subconfigurations of points and lines common to all the three hyperplanes comprising a given Veldkamp line) and the types of the hyperplanes they are composed of. These findings may lend themselves into important physical applications, especially in view of recent emergence of a variety of closely related finite geometrical concepts linking quantum information with black holes.

description: This article aims to provide an overview of 13th-century Syriac poetry through the study of two poems by Bar Hebraeus, a pioneering poet of his time, providing an overview of this art form during that period. These two poems delve into and explore the dimensions of love and friendship. The second poem is, in fact, a collection of two intimately related compositions. After a general introduction to Syriac poetry and the particularities of Bar Hebraeus’ poetry, the analysis focuses on the translation and interpretation of these two poems, which were initially translated into Arabic. The translation into French enhances their dissemination, underscoring the significance of this study in accessing these texts.
