The influence of iron availability on nitrogen assimilation in the marine diatom thalassiosira weissflogii
Creators: name: Milligan, Allen James
Publisher: name: University of British Columbia
Year: 2009

description: Since the recognition of iron-limited, high nitrate, low chlorophyll (HNLC) regions of the ocean, iron limitation has been hypothesized to limit the assimilation of nitrate by diatoms. To determine the influence of iron availability on nitrogen assimilatory enzymes, in vitro enzyme assays were developed and optimized for urease and nitrite reductase. Both assays were able to account for 100% or more of the incorporated nitrogen when growing on urea or nitrate as the sole nitrogen source. Cultures of Thalassiosira weissflogii (Grunow) Fryxell et Hasle (clone Actin) were grown under non-steady-state Fe-limited and Fe-replete conditions using artificial seawater medium. Iron-limited cultures suffered from decreased efficiency of photosystem II as indicated by variable fluorescence (Fv/Fm)- Under Fe-replete conditions, in vitro nitrate reductase (NR) activity was rate limiting to nitrogen assimilation and in vitro nitrite reductase (NiR) activity was 100-fold higher. Under iron limitation, cultures excreted up to 100 fmol NO2 cell-1 d-1 and NiR activities declined by 50-fold while internal NO2- pools remained relatively constant. Activities of both NR and NiR remained in excess of nitrogen incorporation rates throughout iron limited growth indicating that the supply of reductant to NiR may be responsible for the limitation of nitrogen assimilation at the nitrite reduction step. Urease activity showed no response to iron limitation. Carbon:nitrogen ratios were equivalent in both iron conditions indicating that relative to carbon, nitrogen was incorporated at similar rates whether iron was limiting growth or not. Steady-state long-term iron limitation of T. weissflogii using the artificial culture medium Aquil produced similar results, although NO2- efflux rates were much lower (10 fmol NO2- cell-1 d-1). If inferences from a single species may be applied to a mixed assemblage then, according to this work, diatoms in HNLC regions are not deficient in their ability to assimilate nitrate when Fe-limited. Rather, it appears that diatoms are limited in their ability to process photons within the photosynthetic electron transport chain which results in nitrite reduction becoming the rate limiting step in nitrogen assimilation. This appears to be the case whether limiting iron is supplied either in non-steady or steady states. [Scientific formulae used in this abstract could not be reproduced.]

description: The possibility of formation of Bose-Einstein Condensation (BEC) is studied in $pp$ collisions at $\sqrt s$ = 7 TeV at the Large Hadron Collider. A thermodynamically consistent non-extensive formulation of the identified hadron transverse momentum distributions is used to estimate the critical temperature required to form BEC of charged pions, which are the most abundant species in a multi-particle production process in hadronic and nuclear collisions. The obtained results have been contrasted with the systems produced in Pb-Pb collisions to have a better understanding. We observe an explicit dependency of BEC critical temperature and number of particles in the pion condensates on the non-extensive parameter $q$, which is a measure of degree of non-equilibrium -- as $q$ decreases, the critical temperature increases and approaches to the critical temperature obtained from Bose-Einstein statistics without non-extensivity. Studies are performed on the final state multiplicity dependence of number of particles in the pion condensates in a wide range of multiplicity covering hadronic and heavy-ion collisions, using the inputs from experimental transverse momentum spectra.

description: Recent interest in topological nature in condensed matter physics has revealed the essential role of Berry curvature in anomalous Hall effect (AHE). However, since large Hall response originating from Berry curvature has been reported in quite limited materials, the detailed mechanism remains unclear at present. Here, we report the discovery of a large AHE triggered by a pressure-induced magnetic phase transition in elemental $α$-Mn. The AHE is absent in the non-collinear antiferromagnetic phase at ambient pressure, whereas a large AHE is observed in the weak ferromagnetic phase under high pressure despite the small averaged moment of $\sim 0.02 μ_B$/Mn. Our results indicate that the emergence of the AHE in $α$-Mn is governed by the symmetry of the underlying magnetic structure, providing a direct evidence of a switch between a zero and non-zero contribution of the Berry curvature across the phase boundary. $α$-Mn can be an elemental and tunable platform to reveal the role of Berry curvature in AHE.

description: Diagnostic datasets that can detect biased models are an important prerequisite for bias reduction within natural language processing. However, undesired patterns in the collected data can make such tests incorrect. For example, if the feminine subset of a gender-bias-measuring coreference resolution dataset contains sentences with a longer average distance between the pronoun and the correct candidate, an RNN-based model may perform worse on this subset due to long-term dependencies. In this work, we introduce a theoretically grounded method for weighting test samples to cope with such patterns in the test data. We demonstrate the method on the GAP dataset for coreference resolution. We annotate GAP with spans of all personal names and show that examples in the female subset contain more personal names and a longer distance between pronouns and their referents, potentially affecting the bias score in an undesired way. Using our weighting method, we find the set of weights on the test instances that should be used for coping with these correlations, and we re-evaluate 16 recently released coreference models.

description: The short-distance behaviour of the hadronic light-by-light (HLbL) contribution to $(g-2)_μ$ has recently been studied by means of an operator product expansion in a background electromagnetic field. The leading term in this expansion has been shown to be given by the massless quark loop, and the non-perturbative corrections are numerically very suppressed. Here, we calculate the perturbative QCD correction to the massless quark loop. The correction is found to be fairly small compared to the quark loop as far as we study energy scales where the perturbative running for the QCD coupling is well-defined, i.e.~for scales $μ\gtrsim 1\, \mathrm{GeV}$. This should allow to reduce the large systematic uncertainty associated to high-multiplicity hadronic states.

description: I consider general interacting systems of quantum particles in one spatial dimension. These consist of bosons or fermions, which can have any number of components, arbitrary spin or a combination thereof, featuring low-energy two- and multiparticle interactions. The single-particle dispersion can be Galilean (non-relativistic), relativistic, or have any other form that may be relevant for the continuum limit of lattice theories. Using an algebra of generalized functions, statistical transmutation operators that are genuinely unitary are obtained, putting bosons and fermions in a one-to-one correspondence without the need for a short-distance hard core. In the non-relativistic case, low-energy interactions for bosons yield, order by order, fermionic dual interactions that correspond to the standard low-energy expansion for fermions. In this way, interacting fermions and bosons are fully equivalent to each other at low energies. While the Bose-Fermi mappings do not depend on microscopic details, the resulting statistical interactions heavily depend on the kinetic energy structure of the respective Hamiltonians. These statistical interactions are obtained explicitly for a variety of models, and regularized and renormalized in the momentum representation, which allows for theoretically and computationally feasible implementations of the dual theories. The mapping is rewritten as a gauge interaction, and one-dimensional anyons are also considered.

description: Incineration of refuse in incineration plants produces toxic dusts in the waste gas filters which have to be disposed of Vitrification is one possibility of immobilization of such dusts which are contaminated by heavy metals, sulphates and Chlorides. Under oxidizing melting conditions, alkaline sulphates a n d Chlorides would volatilize and would have to be precipitated again. Therefore, in this work reducing melts were used. Thus, it was possible to reduce the sulphate to sulphide and to incorporate the latter in the glass matrix to an efficiency of up to 100%. This is experimentally proved by melting batch compositions of a filter ash from a refuse incineration plant with glass forming additives as well as model glasses. The reduction of CaSO₄ and formation of sulphides is induced by means of suitable additions of the Clements carbon, iron, zinc, titanium, manganese, Silicon, and aluminium, separately and in combination. The sulphides CaS, FeS, ZnS, MnS and AI₂S₃ are present in the melt product mainly in giassy form and only for a small part in a crystalline phase. The melts with additions of manganese and Silicon show the best properties with respect tc vitrification, incorporation of the sulphur and hydrolytic resistance of the product. By means of leaching tests using the Soxhlet equipment, products of great hydrolitic resistance are proved falling under the hydrolytic class III at least.

In this scheme, the kaon whose state is to be teleported collides with one of the two entangled kaons in an Einstein-Podolsky-Rosen state. Subsequent detection of the outgoing particles of the collision completes the two-qubit projection on Alice side. There appear novel features, which connects quantum information science with fundamental laws of particle physics.

description: The present work is based on investigations of aluminum oxide containing lead glasses. The aim was to decrease the costs in the production of lead glass by addition of alkalis other than potassium and soda. Feldspar and nepheline from different sources were employed. During the melting process inhomogeneities, cords, knots and blisters arise the origin of which could be detected by means of Raman spectroscopic measurement on the glasses. This could be achieved also for very tiny inclusions, where other methods such as light microscopy fall. Only results which can be generalized are considered in this work. Raman spectroscopy has proven to be an excellent method to determine the contents of gas bubbles by means of the rotational spectra of the gases or espectively to trace structural changes back from the mineral to the homogeneous glass via the vibrational spectra of the solids. Thus, the development within a cord can be demonstrated and the origin of knots can be explained. The use of this method in explaining defects, taking aluminum oxide containing lead glasses as an example, is presented by various investigations. The structural inhomogeneities in the glasses may be traced back to their origins. i.e., the glasses "have a memory" of their raw materials.

description: Microfinance is an initiative which seeks to address financial inclusion, micro-entrepreneurship, and poverty reduction without over burdening governments. However, the current sector of microfinance is still heavily dependent on the good will of donors. The over-reliance on donations is a feature which threatens the long term sustainability of microfinance. Much has been written about this reliance, but research to date hasn’t empirically examined the effect of regulation as a mediator. This is a critical area of study because regulation directly affects Microfinance Institutions’ (MFI) innovation, and innovation is what shapes the future of microfinance. This thesis considers the role that regulation plays in affecting MFI’s and their ability to innovate in products, services and long-term sustainability via access to capital. Interviews were undertaken with stakeholders in MFI’s, NGO’s, Self-Regulating Bodies, and Regulators in India, Pakistan, and Bangladesh. This thesis discusses findings from interviews in relation to regulatory measures regarding financial self-sustainability of MFI’s. The conclusions of this thesis have implications for policy and inform the microfinance literature.

description: The corrosion resistance of soda-lime-silica glass bottles toward the action of aqueous Solutions of citric, acetic and oxalic acids was studied and compared with that toward HCl and water. The corrosion resistance was tested by subjecting the internal surface of the bottles to the action of Solutions of different concentrations of the organic acids at 95 °C for periods in the ränge of 15 min to 6 h. The quantities of Na₂O and SiO₂ extracted from the bottles under the conditions of attack were taken as a measure of the resistance to corrosion. The results obtained indicated that the extraction of Na₂O by Solutions of low concentrations of the different acids and wate? can be arranged in the following order: H₂O > citric acid > acetic acid > HCl > oxalic acid. Such behaviour was found to follo\ the order of the solubility of the corresponding sodium salts formed with the aqueous Solutions rather than the proton availabilit: in these Solutions. The relative magnitude of dissolution of SiO₂ was found to follow another order: H₂O > HCl > oxalic acid > citric acid > aceti acid. The decreasing solubility of SiO₂ by the organic acids, in comparison with that by HCl or water, was attributed to the formatio; of Oxalate, citrate and acetate complexes with silica which cover the glass surface and retard further dissolution of silica. Differences between the various organic acids in the dissolution of Na₂O or SiO₂ were not observed by increasing their concer trations. This behaviour was attributed to the increase in the concentration of the organosilicon Compound formed which is adsorbe on the glass surface acting as an effective barrier to further dissolution of glass.

description: Obtaining a better understanding of intermediate-mass black holes (IMBHs) is crucial, as their properties could shed light on the origin and growth of their supermassive counterparts. Massive star-forming clumps, which are present in a large fraction of massive galaxies at $z \sim$ 1-3, are amongst the venues wherein IMBHs could reside. We perform a series of Fokker-Planck simulations to explore the occurrence of tidal disruption (TD) and gravitational wave (GW) events about an IMBH in a massive star-forming clump, modelling the latter so that its mass ($10^8 \,{\rm M}_{\odot}$) and effective radius ($100$ pc) are consistent with the properties of both observed and simulated clumps. We find that the TD and GW event rates are in the ranges $10^{-6}$-$10^{-5}$ and $10^{-8}$-$10^{-7}$ yr$^{-1}$, respectively, depending on the assumptions for the initial inner density profile of the system ($ρ\propto r^{-2}$ or $\propto r^{-1}$) and the initial mass of the central IMBH ($10^5$ or $10^3\,{\rm M}_{\odot}$). By integrating the GW event rate over $z$ = 1-3, we expect that the Laser Interferometer Space Antenna will be able to detect $\sim$2 GW events per yr coming from these massive clumps; the intrinsic rate of TD events from these systems amounts instead to a few $10^3$ per yr, a fraction of which will be observable by, e.g. the Square Kilometre Array and the Advanced Telescope for High Energy Astrophysics. In conclusion, our results support the idea that the forthcoming GW and electromagnetic facilities may have the unprecedented opportunity of unveiling the lurking population of IMBHs.

For the first time in a cuprate, mobile charge carriers, lattice, and magnetism all show anomalies at a distinct critical pressure in the same experimental setting. Furthermore, the Raman spectral changes are similar to that seen traversing the superconducting dome with doping, suggesting that the critical pressure at 21 GPa is related to the much discussed critical point at optimal doping.

description: One-dimensional quantum systems admit duality relations that put hard core spinless bosons and fermions in one-to-one correspondence via Girardeau's mapping theorem. The simplest models of soft bosons interacting via zero-range potentials can also be mapped onto dual interacting fermions. However, a systematic approach to one-dimensional statistical transmutation for arbitrary low-energy interactions in the spinless and spinful or multicomponent cases has remained elusive. I develop a general theory of local unitary transformations between one-dimensional quantum systems of bosons and fermions with arbitrary spin or internal structure, single-particle dispersion -- including non-relativistic, relativistic or otherwise -- and low-energy interactions in the universal regime. These transformations generate families of new duality relations and models that relate the strong and weak coupling limits of the respective dual theories.

description: The modular nature and unique electronic properties of two-dimensional (2D) covalent organic frameworks (COFs) make them an attractive option for applications in catalysis, optoelectronics, and spintronics. The fabrications of such devices often involve interfaces formed between COFs and substrates. In this work, we employ the first-principles GW approach to accurately determine the quasiparticle electronic structure of three 2D carbonyl bridged heterotriangulene-based COFs featuring kagome lattice, with their properties ranging from a semi-metal to a wide-gap semiconductor. Moreover, we study the adsorption of these COFs on Au(111) surface and characterize the quasiparticle electronic structure at the heterogeneous COF/Au(111) interfaces. To reduce the computational cost, we apply the recently developed dielectric embedding GW approach and show that our results agree with existing experimental measurement on the interfacial energy level alignment. Our calculations illustrate how the many-body dielectric screening at the interface modulates the energies and shapes of the kagome bands, the effective masses of semiconducting COFs, as well as the Fermi velocity of the semi-metallic COF.

All compound and quasi-compound resonances observed in total cross-section data are matched, and on seeking solutions of the method at negative energies, all sub-threshold states in 13C and 13N are predicted with the correct spin-parities and with reasonable values for their energies. A collective-model prescription has been used to define the initiating nucleon-12C interactions and via use of orthogonalizing pseudo-potentials, account is made of the Pauli principle. Information is extracted on the underlying structure of each state in the compound systems by investigating the zero-deformation limit of the results.

description: We present first results from a major program of methane filter photometry for low-mass stars and brown dwarfs. The definition of a new methane filter photometric system is described. A recipe is provided for the differential calibration of methane imaging data using existing 2MASS photometry. We show that these filters are effective in discriminating T dwarfs from other types of stars, and demonstrate this with Anglo-Australian Telescope observations using the IRIS2 imager. Methane imaging data and proper motions are presented for ten T dwarfs identified as part of the 2MASS "Wide Field T Dwarf Search" -- seven of them initially identified as T dwarfs using methane imaging. We also present near-infrared moderate resolution spectra for five T dwarfs, newly discovered by this technique. Spectral types obtained from these spectra are compared to those derived from both our methane filter observations, and spectral types derived by other observers. Finally, we suggest a range of future programs to which these filters are clearly well suited: the winnowing of T dwarf and Y dwarf candidate objects coming from the next generation of near-infrared sky surveys; the robust detection of candidate planetary-mass brown dwarfs in clusters; the detection of T dwarf companions to known L and T dwarfs via deep methane imaging; and the search for rotationally-modulated time-variable surface features on cool brown dwarfs.

Memory changes across the adult lifespan: formation of gains and losses
Creators: name: Mori, Monica Sachiko
Publisher: name: University of British Columbia
Year: 2009

description: This experiment investigated memory changes across the adult lifespan and some factors that might be associated with these changes. Adult participants of all ages (16 to 83 years old) were asked to orally describe scenic color photographs, and then following a delay, to re-describe these pictures from memory. Given information is objective, physical objects and their attributes that are depicted in a target picture, whereas beyond information is subjective, personal experiences and inferences that are not depicted in a target picture per se but are associated with a target picture. Chapter 3 examined the content of these picture descriptions for the amount of given and beyond information that was encoded and retrieved about target pictures. The results indicated an age-related decline in memory for given information and preserved memory for beyond information. Chapter 4 examined the relationship between perceptual and verbal ability and memory for given and beyond information. Perceptual ability was assessed by self-report measures of auditory and visual ability and verbal ability was measured by a standardized test. The results indicated that an age-related improvement in verbal ability, but not an age-related decline in perceptual ability, was related to memory for given and beyond information. Chapter 5 explored age-related changes in memory for feminine and masculine information across the adult female lifespan. Feminine and masculine information is information that would be considered exclusively relevant to young women and men, respectively. The results indicated an age-related increase in memory for feminine information and no age-related change in memory for masculine information. The divergent age-related changes in memory for given and beyond information and for feminine and masculine information were interpreted in terms of a developmental approach to schema theory and the lifespan psychology notions of selective optimization with compensation and loss in the service of growth. The present study suggests an integration between the domains of personality and cognitive psychology as one avenue for future research that could lead to a more complete understanding of memory and aging.
gamma+gamma --> pi+pi, K+K : leading term QCD vs handbag model

description: The "handbag" model was proposed as an alternative, at the present day energies, to the leading term QCD predictions for some hard exclusive processes. The recent precise data from the Belle Collaboration on the large angle cross sections $γγ--> ππ, KK $ allow a check of these two approaches to be performed. It is shown that the handbag model fails to describe the data from Belle, while the leading term QCD predictions are in reasonable agreement with these data

description: We report on an experimental realization of a two-dimensional magneto-optical trap (2D-MOT) that allows the generation of cold atomic beams of 39K and 41K bosonic potassium isotopes. The high measured fluxes up to 1.0x10^11 atoms/s and low atomic velocities around 33 m/s are well suited for a fast and reliable 3D-MOT loading, a basilar feature for new generation experiments on Bose-Einstein condensation of dilute atomic samples. We also present a simple multilevel theoretical model for the calculation of the light-induced force acting on an atom moving in a MOT. The model gives a good agreement between predicted and measured flux and velocity values for our 2D-MOT.

description: This paper describes the MediaEval 2020 \textit{Predicting Media Memorability} task. After first being proposed at MediaEval 2018, the Predicting Media Memorability task is in its 3rd edition this year, as the prediction of short-term and long-term video memorability (VM) remains a challenging task. In 2020, the format remained the same as in previous editions. This year the videos are a subset of the TRECVid 2019 Video-to-Text dataset, containing more action rich video content as compared with the 2019 task. In this paper a description of some aspects of this task is provided, including its main characteristics, a description of the collection, the ground truth dataset, evaluation metrics and the requirements for participants' run submissions.

description: We predict a new spatial quantum correlation in light propagating through a multiple scattering random medium. The correlation depends on the quantum state of the light illuminating the medium, is infinite range, and dominates over classical mesoscopic intensity correlations. The spatial quantum correlation is revealed in the quantum fluctuations of the total transmission or reflection through the sample and should be readily observable experimentally.

description: The radiation of linear momentum imparts a recoil (or "kick") to the center of mass of a merging black hole binary system. Recent numerical relativity calculations have shown that eccentricity can lead to an approximate 25% increase in recoil velocities for equal-mass, spinning binaries with spins lying in the orbital plane ("superkick" configurations) [U Sperhake et al. Phys. Rev. D 101 (2020) 024044 (arXiv:1910.01598)]. Here we investigate the impact of nonzero eccentricity on the kick magnitude and gravitational-wave emission of nonspinning, unequal-mass black hole binaries. We confirm that nonzero eccentricities at merger can lead to kicks which are larger by up to ~25% relative to the quasicircular case. We also find that the kick velocity $v$ has an oscillatory dependence on eccentricity, that we interpret as a consequence of changes in the angle between the infall direction at merger and the apoapsis (or periapsis) direction.

description: In a sample of six young open clusters we investigated 1753 objects using the narrow band, three filter Delta a photometric system resulting in the detection of eleven bona-fide magnetic chemically peculiar (CP) stars and five Be or metal-weak stars. The results for the distant cluster NGC 3105 is most important because of the still unknown influence of the global metallicity gradient of the Milky Way. These findings confirm that CP stars are present in open clusters of very young ages (log t > 6.90) at galactocentric distances up to 11.4 kpc. For all programme clusters the age, reddening, and distance modulus were derived using the corresponding isochrones. Some additional variable stars within Stock 16 could be identified by comparing different photometric studies.
