description: An algebra $\cal{R}$ is called an extension of the algebra $M$ by $B$ if $M^2=0$, $M$ is an ideal of $\cal{R}$ and $\cal{R}$$/M\cong B$ as algebras. In this paper, by using the Gröbner-Shirshov bases, we characterize completely the extensions of $M$ by $B$. An algorithm to find the conditions of an algebra $A$ to be an extension of $M$ by $B$ is obtained.

description: Understanding the gas abundance distribution is essential when tracing star formation using molecular line observations. Changing density and temperature conditions cause gas to freeze-out onto dust grains, and this needs to be taken into account when modeling a collapsing molecular cloud. This study aims to provide a realistic estimate of the CO abundance distribution throughout the collapse of a molecular cloud. We provide abundance profiles and synthetic spectral lines which can be compared to observations. We use a 2D hydrodynamical simulation of a collapsing cloud and subsequent formation of a protoplanetary disk as input for the chemical calculations. From the resulting abundances, synthetic spectra are calculated using a molecular excitation and radiation transfer code. We compare three different methods to calculate the abundance of CO. Our models also consider cosmic ray desorption and the effects of an increased CO binding energy. The resulting abundance profiles are compared to observations from the literature and are found to agree well. The resulting abundance profiles agree well with analytic approximations, and the corresponding line fluxes match observational data. Our developed method to calculate abundances in hydrodynamical simulations should greatly aid in comparing these to observations, and can easily be generalized to include gas-phase reaction networks.

A stress-strain model for the undrained response of oil sand
Creators: name: Cheung, Ka Fai Henry
Publisher: name: University of British Columbia
Year: 2010

description: An efficient undrained model for the deformations analysis of oil sand masses upon undrained loading is presented in this thesis. An analysis which couples the soil skeleton and pore fluids is used. The soil skeleton is modeled as a non-linear elastic-plastic isotropic material. In undrained conditions, the constitutive relationships for the pore fluids are formulated based on the ideal gas laws. The coupling between the soil skeleton and the pore fluids is based upon volume compatibility. The undrained model was verified with the experimental results and one dimensional expansion of soil sand cores. Comparisons between computed and measured responses are in good agreement and suggest that this model may prove useful as a tool in evaluating undrained response of oil sand. The response of a wellbore in oil sand upon unloading was analyzed using the developed model. Such analysis are important in the rational design of oil recovery systems in oil sand.

description: Using a numerical approach based on the coupling of the discrete and finite element methods, we explore the variation of the bulk modulus K of soft particle assemblies undergoing isotropic compression. As the assemblies densify under pressure-controlled boundary conditions, we show that the non-linearities of K rapidly deviate from predictions standing on a small-strain framework or the Equivalent Medium Theory (EMT). Using the granular stress tensor and extracting the bulk properties of single representative grains under compression, we propose a model to predict the evolution of K as a function of the sample's solid fraction and a reference state as the applied pressure P tends to zero. The model closely reproduces the trends observed in our numerical experiments confirming the behavior scalability of soft particle assemblies from the individual particle scale. Finally, we present the effect of the interparticle friction on K's evolution and how our model easily adapts to such a mechanical constraint.

description: In this overview I sketch briefly the path to the so-called {\em t-J model} derived for the first time 30 years ago and provide its original meaning within the theory of strongly correlated magnetic metals with a non-Fermi (non-Landau) liquid ground state. An emergence of the concept of {\em real space pairing}, is discussed in a historical prospective. A generalization of this model to the many-orbital situation is briefly discussed. The emphasis is put on didactical exposition of ideas, as they were transformed into mathematical language. The concept of {\em hybrid pairing} is introduced in the same context at the end.

description: The axion is a well-motivated candidate for the inflaton, as the radiative corrections that spoil many single-field models are avoided by virtue of its shift symmetry. However, axions generically couple to gauge sectors. As the axion slow-rolls during inflation, this coupling can cause the production of a non-diluting thermal bath, a situation known as "warm inflation." This thermal bath can dramatically alter inflationary dynamics and observable predictions. In this paper, we demonstrate that a thermal bath can form for a wide variety of initial conditions. Furthermore, we find that axion inflation becomes warm over a large range of couplings, and explicitly map the parameter space for two axion inflation potentials. We show that in large regions of parameter space, axion inflation models once assumed to be safely "cold" are in fact warm, and must be reevaluated in this context.

description: The New Horizons spacecraft will achieve a wide range of measurement objectives at the Pluto system, including color and panchromatic maps, 1.25-2.50 micron spectral images for studying surface compositions, and measurements of Pluto's atmosphere (temperatures, composition, hazes, and the escape rate). Additional measurement objectives include topography, surface temperatures, and the solar wind interaction. The fulfillment of these measurement objectives will broaden our understanding of the Pluto system, such as the origin of the Pluto system, the processes operating on the surface, the volatile transport cycle, and the energetics and chemistry of the atmosphere. The mission, payload, and strawman observing sequences have been designed to acheive the NASA-specified measurement objectives and maximize the science return. The planned observations at the Pluto system will extend our knowledge of other objects formed by giant impact (such as the Earth-moon), other objects formed in the outer solar system (such as comets and other icy dwarf planets), other bodies with surfaces in vapor-pressure equilibrium (such as Triton and Mars), and other bodies with N2:CH4 atmospheres (such as Titan, Triton, and the early Earth).

description: Galaxy morphologies, kinematics, and stellar populations are thought to be linked to each other. However, both simulations and observations have pointed out mismatches therein. In this work, we study the nature and origin of the present-day quenched, bulge-dominated, but dynamically cold galaxies within a stellar mass range of $10.3\,\leqslant\,\log\,M_{\ast}/\mathrm{M_{\odot}}\,\leqslant\,11.2$ in the IllustrisTNG-100 Simulation. We compare these galaxies with a population of normal star-forming dynamically cold disc galaxies and a population of normal quenched dynamically hot elliptical galaxies within the same mass range. The populations of the present-day quenched and bulge-dominated galaxies (both being dynamically cold and hot) used to have significantly higher star-formation rates and flatter morphologies at redshift of $z\sim 2$. They have experienced more frequent larger mass-ratio mergers below $z \sim 0.7$ in comparison to their star-forming disc counterparts, which is responsible for the formation of their bulge-dominated morphologies. The dynamically cold populations (both being star-forming and quenched) have experienced more frequent prograde and tangential mergers especially below $z \sim 1$, in contrast to the dynamically hot ellipticals, which have had more retrograde and radial mergers. Such different merging histories can well explain the differences on the cold and hot dynamical status among these galaxies. We point out that the real-world counterparts of these dynamically cold and hot bulge-dominated quenched populations are the fast- and slow-rotating early-type galaxies, respectively, as seen in observations and hence reveal the different evolution paths of these two distinct populations of early-type galaxies.

description: CONTEXT: The four-quadrant phase mask stellar coronagraph, introduced by D. Rouan et al., is capable of achieving very high dynamical range imaging and was studied in the context of the direct detection of extra-solar planets. Achromatic four-quadrant phase mask is currently being developed for broadband IR applications. AIMS: We report on laboratory and on-sky tests of a prototype coronagraph in the visible. This prototype, the achromatic hybrid phase knife coronagraph, was derived from the four-quadrant phase mask principle. METHODS: The instrumental setup implementing the coronagraph itself was designed to record the pre- and post-coronagraphic images simultaneously so that an efficient real-time image selection procedure can be performed. We describe the coronagraph and the associated tools that enable robust and repeatable observations. We present an algorithm of image selection that has been tested against the real on-sky data of the binary star HD80081 (* 38 Lyn). RESULTS Although the observing conditions were poor, the efficiency of the proposed method is proven. From this experiment, we derive procedures that can apply to future focal instruments associating adaptive optics and coronagraphy, targeting high dynamic range imaging in astronomy, such as detecting extra-solar planets.

Second language learners' beliefs about language learning and their use of learning strategies : a study of college students of English in Taiwan

description: This study investigated the beliefs about language learning and use of language learning strategies by college EFL students in Taiwan. The relationship between learners' beliefs and strategy use was also studied. A total of 505 students enrolled in undergraduate English classes in Taiwan participated in the study. An English Learning Questionnaire, which was composed of two self-report measures Horwitz's (1987) Beliefs About Language Learning Inventory and Oxford's (1989) Strategy Inventory for Language Learning and an Individual Background Questionnaire, were translated into Chinese and administered to the students during their regular English classes. Factor analyses were computed to determine the underlying composite belief variables and composite strategy variables. The results showed that many students had positive self-efficacy about learning English. They endorsed ideas about foreign language aptitude and the importance of practice and formal structural studies. These students also reported using a variety of learning strategies, with formal oral-practice strategies and compensation strategies used more frequently and cognitive-memory strategies, least frequently. Two significant canonical correlations between the composite belief and strategy variables were obtained. The first significant linkage related language learners' feelings of self-efficacy about learning English to their use of all types of learning strategies, especially functional practice strategies. The second significant linkage related learners' beliefs about the value and nature of learning spoken English to the use of formal oral-practice strategies. The results of this study suggested that the relationships between beliefs and strategy use might not be unidirectional. As learners' beliefs likely affect their learning strategy use, the use of learning strategies may also influence learners' self-efficacy and other beliefs about language learning. In addition, female students were found to use social strategies more often than male students, and foreign language majors had a greater tendency to believe in foreign language aptitude than did other majors. In brief, the results of this study provided empirical support for a connection between language learners' beliefs and their learning strategy use. A better understanding of the beliefs and learning strategy use of the EFL students in Taiwan, as well as practical suggestions for EFL instruction in Taiwan, has been achieved
Magnetoresistance and collective Coulomb blockade in super-lattices of ferromagnetic CoFe nanoparticles

description: We report on transport properties of millimetric super-lattices of CoFe nanoparticles surrounded by organic ligands. R(T)s follow R(T) = R_0.exp(T/T_0)^0.5 with T_0 ranging from 13 to 256 K. At low temperature I(V)s follow I=K[(V-V_T)/V_T]^ksi with ksi ranging 3.5 to 5.2. I(V) superpose on a universal curve when shifted by a voltage proportional to the temperature. Between 1.8 and 10 K a high-field magnetoresistance with large amplitude and a strong voltage-dependence is observed. Its amplitude only depends on the magnetic field/temperature ratio. Its origin is attributed to the presence of paramagnetic states present at the surface or between the nanoparticles. Below 1.8 K, this high-field magnetoresistance abruptly disappears and inverse tunnelling magnetoresistance is observed, the amplitude of which does not exceed 1%. At this low temperature, some samples display in their I(V) characteristics abrupt and hysteretic transitions between the Coulomb blockade regime and the conductive regime. The increase of the current during these transitions can be as high as a factor 30. The electrical noise increases when the sample is near the transition. The application of a magnetic field decreases the voltage at which these transitions occur so magnetic-field induced transitions are also observed. Depending on the applied voltage, the temperature and the amplitude of the magnetic field, the magnetic-field induced transitions are either reversible or irreversible. These abrupt and hysteretic transitions are also observed in resistance-temperature measurements. They could be the soliton avalanches predicted by Sverdlov et al. [Phys. Rev. B 64, 041302 (R), 2001] or could also be interpreted as a true phase transition between a Coulomb glass phase to a liquid phase of electrons.

description: In this work we focus on the phase space singularities of interactive quintessence model in the presence of matter fluid. This model is related to swampland studies, that the outcomes affect all these Swampland related models with the same dynamical system. We shall form the dynamical system corresponding to the cosmological system, which is eventually autonomous, and by using the dominant balances technique we shall investigate the occurrence or not of finite-time singularities. Our results indicate that the dynamical system of the model may develop finite-time singularities, but these are not general singularities, like in the case that the matter fluids were absent, in which case singularities occurred for general initial conditions. Hence, the presence of matter fluids affects the dynamical system of the cosmological system, making the singularities to depend on the initial conditions, instead of occurring for general initial conditions.

description: We report a radio detection of supernova SN 2004ip in the circumnuclear region of the luminous infrared galaxy IRAS 18293-3413, using Very Large Array (VLA) observations at 8.4 GHz on 11 June 2007. SN 2004ip had been previously discovered at near-infrared wavelengths using adaptive optics observations, but its nature (core-collapse or thermonuclear) could not be definitely established. Our radio detection, about three years after the explosion of the supernova, indicates a prominent interaction of the ejecta of SN 2004ip with the circumstellar medium, confirming that the supernova was a core-collapse event (probably Type II), and thus strongly suggesting that its progenitor was a massive star with a significant mass-loss prior to its explosion. SN 2004ip has a 8.4 GHz luminosity of 3.5E27 erg/s/Hz, about twice as bright as SN 2000ft in NGC 7469 at a similar age, and given its projected distance to the nucleus (~500 pc), is one of the closest of all known radio SNe to a galaxy nucleus, and one of the brightest radio SNe ever.

An evaluation of the flat dilatometer as an insitu testing device
Creators: name: McPherson, Ian Duncan
Publisher: name: University of British Columbia
Year: 2010

description: The results from the use of the dilatometer (Marchetti 1975, 1980) at 4 sites in British Columbia are presented. Comparisons are drawn between the dilatometer and other insitu test devices, including the piezo-friction cone, self-boring and Menard pressuremeters and field vane. Soils tested included saturated deltaic deposits, a sensitive plastic clay and a saturated, hydraulically placed fill. Overall the dilatometer proved to be an extremely effective device. It had a low capital cost, required a minimum of support equipment and was simple to use. The data was repeatable and easily reduced using a computer programme. Computer output, both graphical and tabular, is easily amenable to interpretation to an engineer in the field. For the most part the results in this thesis support Marchetti's empirical correlations with the following exceptions: ( i) determination of K0 in sands, ( ii) determination of a deformation modulus in clay, and (iii) in overconsolidated silts where it is believed that abnormal pore pressures caused the empirical correlations to breakdown. The dilatometer is an insitu, total stress, penetration device which cannot be analysed in a fundamental manner. Elastic theory is inapplicable because of plastic straining during blade penetration and probably during membrane expansion. To more critically evaluate the dilatometer, the author designed an electronic research device with exactly the same external dimensions as Marchetti's dilatometer. The aim of the electronic dilatometer is to greatly improve understanding of the simple Marchetti dilatometer by allowing: ( i) a better understanding of the operational characteristics of Marchetti's dilatometer, ( ii) direct measurement of stress on, and deformation of, the membrane, (iii) measurement of pore water pressure before and after halting penetration and during membrane expansion, and ( iv) measurement of the pushing force on the blade.

description: The possible unavailability of urban rail-based transport services due to planned maintenance activities may have significant consequences on the perceived quality of service, thus affecting railway attractiveness. To cope with the mitigation of planned service interruptions and to guarantee a seamless journey and a good travel experience for passengers, it is possible to exploit the existing services differently and/or provide additional on-demand services, such as temporary supplemental bus lines. In this context, this paper aims to develop a mathematical programming model for planning service interruptions due to maintenance considering passenger transport demand dynamics. In particular, the proposed approach deals with service interruptions characterized by a long duration for which timetable adaption strategies are not applicable, suggesting mitigation actions that exploit the already existing services and/or the activation of additional ones, with the aim of minimizing users' inconvenience. In doing so, the planned infrastructure status (i.e., available or under maintenance), as well as the forecasted transport demand, are taken into account to adapt the service accordingly by offering a multimodal transport solution to passengers. To find the best solution, a decomposition solution approach is proposed in combination with a multistage cooperative framework with feedback that models the negotiation process between the involved actors. Finally, the applicability of the proposed approach to real case studies is discussed based on some performance indicators.
Romance and Freedom: Nelson and Winnie Mandela’s Politics of Gender in Three Post-Apartheid Novels
Creators: name: Mari, Lorenzo
Publisher: name: Università degli  Studi di Milano
Year: 2014
Subjects: Nelson Mandela; Winnie Mandela; Fathering/Mothering the Nation; Lewis Nkosi; Njabulo Ndebele; Phaswane Mpe

description: This paper aims to retrace the influence of the politics of gender enacted by Nelson and Winnie Mandela on post-apartheid gender relationships, as represented in three novels: Phaswane Mpe’s Welcome to Our Hillbrow (2001), Njabulo Ndebele’s The Cry of Winnie Mandela (2003) and Lewis Nkosi’s Mandela’s Ego (2006).

Recently, Nelson and Winnie Mandela’s marriage has been also described as the “unusual founding-family romance” (Munro 2014) of the post-apartheid nation. Their marriage lasted from 1958 to 1992, including, thus, the last decades of the anti-apartheid struggle, as well as the demise of the apartheid regime. Their separation, which was due in the first place to Nelson Mandela’s imprisonment and, later, to their divorce, eventually marked the disruption of this founding-family romance, making it “unusual”.

As a consequence, the deconstructive take on Nelson Mandela’s fatherhood and masculinity and Winnie Mandela’s femininity and motherhood which is enacted in the three novels also allows to reassess the possibility of that “founding-family romance”, envisioning an alternative understanding of the origins of the post-apartheid South African nation.

description: In this paper, we prove that two-generator one-relator groups with depth less than or equal to 3 can be effectively embedded into a tower of HNN-extensions in which each group has the effective standard normal form. We give an example to show how to deal with some general cases for one-relator groups. By using the Magnus method and Composition-Diamond Lemma, we reprove the G. Higman, B. H. Neumann and H. Neumann's embedding theorem.

description: The VLTI Spectro Imager (VSI) was proposed as a second-generation instrument of the Very Large Telescope Interferometer providing the ESO community with spectrally-resolved, near-infrared images at angular resolutions down to 1.1 milliarcsecond and spectral resolutions up to R=12000. Targets as faint as K=13 will be imaged without requiring a brighter nearby reference object. The unique combination of high-dynamic-range imaging at high angular resolution and high spectral resolution enables a scientific program which serves a broad user community and at the same time provides the opportunity for breakthroughs in many areas of astrophysic including: probing the initial conditions for planet formation in the AU-scale environments of young stars; imaging convective cells and other phenomena on the surfaces of stars; mapping the chemical and physical environments of evolved stars, stellar remnants, and stellar winds; and disentangling the central regions of active galactic nuclei and supermassive black holes. VSI will provide these new capabilities using technologies which have been extensively tested in the past and VSI requires little in terms of new infrastructure on the VLTI. At the same time, VSI will be able to make maximum use of new infrastructure as it becomes available; for example, by combining 4, 6 and eventually 8 telescopes, enabling rapid imaging through the measurement of up to 28 visibilities in every wavelength channel within a few minutes. The current studies are focused on a 4-telescope version with an upgrade to a 6-telescope one. The instrument contains its own fringe tracker and tip-tilt control in order to reduce the constraints on the VLTI infrastructure and maximize the scientific return.

In silico first identification and modelling of DBP hydrolases in the marine diatom Cylindrotheca closterium
Creators: name: Vingiani, Giorgio Maria
Publisher: name: F1000 Research Limited

description: Enzymes are essential components of biological reactions and play important roles in the scaling and optimization of many industrial processes. Microalgae recently emerged as a novel source of promising enzymes. With recent advances in –omics technologies, it has become easier to identify sequences encoding new enzymes, increasing the likelihood of their characterization and exploitation for biotechnological applications. At present, many studies focused on microalgal enzymes involved in lipid and carotenoid production, already bringing promising results in biofuel and healthcare fields. In the present work the bioremediation potential of the marine diatom Cylindrotheca closterium against phthalate esters (PEs), pollutants leached from plastics and known to be endocrine-disrupting chemicals, was investigated. Two novel PEs hydrolases (provisionally named DBPH1 and DBH2) were identified from C. closterium transcriptome, and for the first time in microalgae. Their CDS were found in a polycistronic transcript and displayed conserved motifs similar to bacterial class IV esterases. In silico approaches were followed for transcriptome mining of these esterases, including their 3D structure resolution and the molecular docking with the expected substrate. The molecular models produced for the two putative hydrolases, despite being based on low homology templates, highlight the possible role of DBPH1 as the primary actor of the degradation of DBP. Unfortunately, the model of DBPH2 was less informative on the function of this second enzyme, for which optimal docking poses could not be detected; however, the polycistronic nature of the transcript could imply a regulatory function for DBPH2, more than a catalytic one. Taken together these results show promising first steps in the discovery and characterization of microalgal enzymes for phthalate bioremediation.

description: Integrated photonic circuits are an integral part of all-optical and on-chip quantum information processing and quantum computer. Deterministically integrated single-photon sources in nanoplasmonic circuits lead to densely packed scalable quantum logic circuits operating beyond the diffraction limit. Here, we report the coupling efficiency of single-photon sources to the plasmonic waveguide, characteristic transmission spectrum, propagation length, decay length, and plasmonic Purcell factor. We simulated the transmission spectrum to find the appropriate wavelength for various width of the dielectric in the metal-dielectric-metal waveguide. We find the maximum propagation length of 3.98 $μ$m for Al$_{2}$O$_{3}$ dielectric-width equal to 140 nm and coupling efficiency to be greater than 82 \%. The plasmonic Purcell factor was found to be inversely proportional to dielectric-width (w), reaching as high as 31974 for w equal to 1 nm. We also calculated quantum properties of the photons like indistinguishability and found that it can be enhanced by plasmonic-nanocavity if single-photon sources are deterministically coupled. We further, propose a scalable metal-dielectric-metal waveguide based quantum logic circuits using the plasmonic circuit and Mach-Zehnder interferometer.

description: We consider galaxy halos formed by dark matter bosons with mass in the range of about a few tens or hundreds eV. A major part of the particles is in a noncondensed state and described under the Thomas-Fermi approach. Derived equations are solved numerically to find the halo density profile. The noncondensed state is supported in the entire halo except compact gravitationally bounded Bose-Einstein condensates. Although the size of these compact objects, also known as Bose stars, depends on interactions between the particles, its upper limit is only about 100 astronomical units. The Bose stars collect the condensed bosons providing a density cusp avoidance in the halo as well as a natural mechanism to prevent overproduction of small halos. Clusters of the Bose stars can also contribute to the halo density profile. The model is analyzed by confronting its predictions with observations of galaxy rotation curves. We employ 22 low surface brightness galaxies and obtain that the model is consistent with the observational data when the particle mass is in the range above about 50 eV and the best fit corresponds to the mass $m=86$ eV. This mass is appropriate for relic dark matter bosons, which decouple just after QCD phase transition.
