description: UDP-glycosyltransferases (UGTs) are important conjugation enzymes found in all kingdoms of life, catalyzing a sugar conjugation with small lipophilic compounds and playing a crucial role in detoxification and homeostasis. The UGT gene family is defined by a signature motif in the C-terminal domain where the uridine diphosphate (UDP)-sugar donor binds. UGTs have been identified in a number of insect genomes over the last decade and much progress has been achieved in characterizing their expression patterns and molecular functions. Here, we present an update of the complete repertoire of UGT genes in Drosophila melanogaster and provide a brief overview of the latest research in this model insect. A total of 35 UGT genes are found in the D. melanogaster genome, localized to chromosomes 2 and 3 with a high degree of gene duplications on the chromosome arm 3R. All D. melanogaster UGT genes have now been named in FlyBase according to the unified UGT nomenclature guidelines. A phylogenetic analysis of UGT genes shows lineage-specific gene duplications. Analysis of anatomical and induced gene expression patterns demonstrate that some UGT genes are differentially expressed in various tissues or after environmental treatments. Extended searches of UGT orthologs from 18 additional Drosophila species reveal a diversity of UGT gene numbers and composition. The roles of Drosophila UGTs identified to date are briefly reviewed, and include xenobiotic metabolism, nicotine resistance, olfaction, cold tolerance, sclerotization, pigmentation, and immunity. Together, the updated genomic information and research overview provided herein will aid further research in this developing field.

description: We revisit our previous work [Phys. Rev. D 95, 096014 (2017)] where neutrino oscillation and nonoscillation data were analyzed in the standard framework with three neutrino families, in order to constrain their absolute masses and to probe their ordering (either normal, NO, or inverted, IO). We include updated oscillation results to discuss best fits and allowed ranges for the two squared mass differences $δm^2$ and $Δm^2$, the three mixing angles $θ_{12}$, $θ_{23}$ and $θ_{13}$, as well as constraints on the CP-violating phase $δ$, plus significant indications in favor of NO vs IO at the level of $Δχ^2=10.0$. We then consider nonoscillation data from beta decay, from neutrinoless double beta decay (if neutrinos are Majorana), and from various cosmological input variants (in the data or the model) leading to results dubbed as default, aggressive, and conservative. In the default option, we obtain from nonoscillation data an extra contribution $Δχ^2 = 2.2$ in favor of NO, and an upper bound on the sum of neutrino masses $Σ< 0.15$ eV at $2σ$; both results - dominated by cosmology - can be strengthened or weakened by using more aggressive or conservative options, respectively. Taking into account such variations, we find that the combination of all (oscillation and nonoscillation) neutrino data favors NO at the level of $3.2-3.7σ$, and that $Σ$ is constrained at the $2σ$ level within $Σ< 0.12-0.69$ eV. The upper edge of this allowed range corresponds to an effective $β$-decay neutrino mass $m_β= Σ/3 = 0.23$ eV, at the sensitivity frontier of the KATRIN experiment.

description: Abstract: We review some unusual facts about the theory of non-relativistic anyons in 2+1 dimensions, and use it as a laboratory to explore how interesting features of non­relativistic field theory correspond to those of many-body quantum mechanics. In particular, we offer an explanation of how Jackiw-Pi vortices arise as the classical limit of certain many-body states in the quantum mechanical theory. Along the way, we make various interesting observations about universal features of the spectrum of anyons subject to different amounts of tuning.

description: This paper uses longitudinal data from three contrasting datasets (matched Labour Force Surveys, the British Household Panel Survey and matched New Earnings Surveys) to estimate the impact of the introduction of the UK minimum wage (in April 1999) on the probability of subsequent employment among those whose wages would have needed to be raised to comply with the minimum. A difference-indifferences estimator is used, based on position in the wage distribution. No significant adverse employment effects are found for any of the four demographic groups considered (adult and youth, men and women) or in any of the three datasets used.

description: Suppose a spacetime $M$ is a quotient of a spacetime $V$ by a discrete group of isometries. It is shown how causality conditions in the two spacetimes are related, and how can one learn about the future causal boundary on $M$ by studying structures in $V$. The relations between the two are particularly simple (the boundary of the quotient is the quotient of the boundary) if both $V$ and $M$ have spacelike future boundaries and if it is known that the quotient of the future completion of $V$ is past-distinguishing. (That last assumption is automatic in the case of $M$ being multi-warped.)

description: The design of new Student Union Building at UBC is implementing a rainwater harvesting system which includes several major components like collection, filtration, disinfection, storage and distribution. This report looks into the storage system of the rainwater harvesting system in addition to the disinfection approaches applicable to the tank. Moreover, the design of the system needs to cater to the LEED platinum+ Certificate requirements. Underground cistern is made to store water in a tank which can utilize different materials for construction. Materials like galvanized steel, poured concrete and polyplastic have been studied to make a tank of around 22m3. Triple bottom analysis was carried out which reflected that concrete is the cheapest option at $250/m3 and with the least environmental impacts and social implications. Furthermore, chlorination and UV disinfection were chosen to be investigated for possible application to the proposed cistern. Chlorination proved to have low operating cost of only $38/yr but with high initial cost of $1186. For UV disinfection, the capital cost is $600 whereas operating and maintenance costs are close to $70/year. Despite the higher operating cost, UV disinfection is recommended since it has no environmental impacts when used in a tank and no social affects.

description: This paper compares Cournot and Bertrand equilibria in a downstream differentiated duopoly in which the input price (wage) paid by each downstream firm is the outcome of a strategic bargain with its upstream supplier (labour union). We show that the standard result that Cournot equilibrium profits exceed those under Bertrand competition - when the differentiated duopoly game is played in imperfect substitutes - is reversible. Whether equilibrium profits are higher under Cournot or Bertrand competition is shown to depend upon the nature of the upstream agents’ preferences, on the distribution of bargaining power over the input price and on the degree of product market differentiation. We find that the standard result holds unless unions are both powerful and place considerable weight on the wage argument in their utility function. One implication of this is that if the upstream agents are profit-maximising firms, then the standard result will obtain.
title: John Henry Newman, the Holy Spirit and the church : an examination of his fundamental pneumatic ecclesiology with special reference to the period 1826-53
Creators: name: Graham, Donald G.
Publisher: name: The Open University
Year: 2004

description: This dissertation brings to light the fundamental place which the Holy Spirit occupies in the ecclesiology of John Henry Newman.

Chapter one describes the historical growth of Newman’s ecclesiology from his Evangelical idea of the Church as an invisible union of believers (1816-24) to his gradual acceptance of the visible dimension of the Church (1824-26) to his affirmation of the Church as a sacramental communion (post-1826).

Chapter two sets forth his trinitarian and incamational grammar and reviews the state of scholarship concerning his pneumatic christology to conclude that there is a lack of work focussing upon his view of the Holy Spirit in the life of the historical Jesus.

Chapter three examines Newman’s view of the congruity of divine personhood and temporal office wherein mediation and animation are hypostatic hallmarks of the offices of the eternal Son and Holy Spirit; it considers the implications of this view for his mariology.

Chapter four refutes charges that Newman’s pneumatic christology is actually an immanent Athanasian christology or is diminished by a deficient view of the humanity of the God-man. The strength of his pneumatic christology is then evinced with reference to events in the life of the God-man from his ontological constitution to his crucifixion.

Chapter five discusses Newman’s view of the Holy Spirit as the ‘leading actor’ in the Easter Mystery, his belief that the resurrection is the origin of ecclesia and the centrality of ascension-pentecost for his ‘Body of Christ’ ecclesiology.

Chapters six and seven test the argument that Newman’s ecclesiology is essentially a sacramental extension of his pneumatic christology with reference to his Essay on the Development of Christian Doctrine (1845). The thesis is that this text does not contain ‘pneumatological deficit’ because Newman invests his epistemological language with pneumatological and christological significance.

description: Abstract: The primitive ontology approach to quantum mechanics seeks to account for quantum phenomena in terms of a distribution of matter in three-dimensional space (or four-dimensional spacetime) and a law of nature that describes its temporal development. This approach to explaining quantum phenomena is compatible with either a Humean or powerist account of laws. In this paper, I offer a powerist ontology in which the law is specified by Bohmian mechanics for a global configuration of particles. Unlike in other powerist ontologies, however, this law is not grounded in a structural power that is instantiated by the global configuration. Instead, I combine the primitive ontology approach with Aristotle’s doctrine of hylomorphism to create a new metaphysical model, in which the cosmos is a hylomorphic substance with an intrinsic power to choreograph the trajectories of the particles.

description: Electron Cyclotron Resonance Ion Sources are currently the most efficient ion sources among those used in facilities dedicated to nuclear physics. The need for a more flexible magnetic field and RF injection system suggested to design and develop a different type of plasma trap, named Flexible Plasma Trap (FPT). The magnetic field of FPT is generated by means of three coils while microwaves in the range 4-7 GHz can be injected by three different inputs, one placed along the axis and two placed radially. FPT can work in different plasma heating schemes so it will be an ideal tool for studies of plasma and multidisciplinary physics. Moreover, a microwave launcher has been designed and installed to the FPT for launching microwaves with a variable tilt angle with respect to the magnetic field. This paper describes the characteristics of the FPT along with the preliminary results of plasma diagnostics.

description: $\mathrm {^{151}Eu^{3+}}$-doped yttrium silicate ($\mathrm {^{151}Eu^{3+}:Y_2SiO_5}$ ) crystal is a unique material that possesses hyperfine states with coherence time up to 6 h. Many efforts have been devoted to the development of this material as optical quantum memories based on the bulk crystals, but integrable structures (such as optical waveguides) that can promote $\mathrm {^{151}Eu^{3+}:Y_2SiO_5}$-based quantum memories to practical applications, have not been demonstrated so far. Here we report the fabrication of type 2 waveguides in a $\mathrm {^{151}Eu^{3+}:Y_2SiO_5}$ crystal using femtosecond-laser micromachining. The resulting waveguides are compatible with single-mode fibers and have the smallest insertion loss of $4.95\ dB$. On-demand light storage is demonstrated in a waveguide by employing the spin-wave atomic frequency comb (AFC) scheme and the revival of silenced echo (ROSE) scheme. We implement a series of interference experiments based on these two schemes to characterize the storage fidelity. Interference visibility of the readout pulse is $0.99\pm 0.03$ for the spin-wave AFC scheme and $0.97\pm 0.02$ for the ROSE scheme, demonstrating the reliability of the integrated optical memory.
Features of the Dynamical Evolution of a Massive Disk of Trans-Neptunian Objects

description: Dynamical features of a massive disk of distant trans-Neptunian objects are considered in the model of the formation of small bodies in the Hill region of a giant gas-dust clump that arose as a result of gravitational instability and fragmentation of the protoplanetary disk. The dynamical evolution of orbits of small bodies under the action of gravitational perturbations from the outer planets and self-gravity of the disk has been studied for a time interval of the order of a billion years. It is shown that the secular effects of the gravitational action of a massive disk of small bodies lead to an increase in the eccentricities of the orbits of individual objects. The result of this dynamical behavior is the creation of a flux of small bodies coming close to the orbit of Neptune. The change in the number of objects surviving in the observable region of distant trans-Neptunian objects (the region of orbits with perihelion distances of 40 < q < 80 AU and semimajor axes 150 < a < 1000 AU), over time depends on the initial mass of the disk. For disks with masses exceeding several Earth masses, there is a tendency to a decrease in the number of distant trans-Neptunian objects surviving in the observable region after evolution for a time interval of the order of the age of the Solar system, with an increase in the initial mass. On the other hand, for most objects, orbital eccentricities decrease under the influence of the self-gravity of the disk. Therefore, the main part of the disk remains in the region of heliocentric distances exceeding 100 AU.
title: Developing Immunotherapy Strategies for Cancer Treatment
Creators: name: Linardakis, Emmanouela
Publisher: name: The Open University
Year: 2003

description: The goal of this thesis was to develop potent tumour cell vaccines that can be used as an effective strategy for cancer treatment. Allogeneic tumour cell vaccines hold great promise for cancer treatment. Cytokine modification has been proven effective in enhancing the immunogenicity of tumour cell vaccines. This work here shows that modification of the allogeneic K1735 cells to express the immunostimulatory cytokines GM-CSF, IL-12 or IFN-ɣ, however, was not effective in augmenting the immunogenicity of the vaccine and irradiated cytokine-modified vaccines could not protect animals from autologous tumour challenge. These data are in agreement with recent literature. Similar results were obtained when K1735 cells were modified to express heat shock proteins. Analysis of the injection site of irradiated K1735 vaccine cells demonstrated that clearance of the K1735 cells from the injection site correlated well with the induction of proinflammatory cytokines and infiltration by non-specific effector cells such as NK cells.

 FMG-induced fusion was next investigated as a novel and effective way of releasing tumour antigens from allogeneic vaccine cells in an immunostimulatory fashion. Expression of the Vesicular Stomatitis Virus G glycoprotein by K1735 or B16 cells lead to the formation of extensive syncytia in vitro. Vaccination of mice with irradiated 2-day fusing allogeneic K1735 or syngeneic B16 cells showed no significant therapeutic benefit relative to irradiated unfused cells. Interestingly, vaccination of mice with a hybrid K1735/B16 fusing vaccine repeatedly lead to significant protective and therapeutic immunity against a B16 challenge. Overall, VSV-G mediated syncitial death was shown to be a highly immunogenic event that promotes the induction of potent specific antitumour immunity in the context of allogeneic vaccines. The mechanism of immunogenicity of fusing hybrid vaccines was investigated.

 Generation of long-term human allogeneic fusing tumour cell vaccines for translation of this work into clinical application was next investigated. A human melanoma cell line stably transduced with the gene for a hyperfusogenic form of the Gibbon ape leukemia virus FMG gene was generated. The Tet-On system of transcriptional control was employed to control gene expression and thus GALV-mediated fusion. Very high levels of fusion could be obtained following the addition of doxocycline in culture. This cell line could form the basis of human melanoma fusing vaccine.

description: The Hopf insulator is a three-dimensional topological insulator outside the standard classification of topological insulators. Here we consider two types of non-Hermitian Hopf insulators, one without and one with the non-Hermitian skin effect. The isolated gapless points of the Hermitian model are broadened into finite regimes in the non-Hermitian models. However, the modulus of the Hopf index remains quantized in the gapped regions. The model without the non-Hermitian skin effect allows an accurate evaluation of its generalized Hopf index and energy spectrum, showing an agreement between the gapless-regime estimations from the systems with periodic- and open- boundary conditions. Near the zero-energy plane, Fermi rings can be observed whenever the Hopf index is quantized at nonzero values, and there is a bulk-boundary correspondence between the modulus of the Hopf index and the number of Fermi rings. The other model manifests the non-Hermitian skin effect in the generalized Brillouin zone and shows the skewed profiles of the bulk states. The Hopf index and energy spectrum are shown to be sensitive to the boundary condition in the presence of the non-Hermitian skin effect.

description: Using the concept of collision time (time delay) introduced by Eisenbud and Wigner and its connection to on-shell intermediate unstable states, we study mesonic resonances in pi-pi and pi-K scattering. The time-delay method proves its usefulness by revealing the spectrum of the well-known rho- and K*-mesons and by supporting some speculations on rho-mesons in the 1200 MeV region. We use this method further to shed some light on more speculative meson resonances, among others the enigmatic scalars. We confirm the existence of chiralons below 1 GeV in the unflavoured and strange meson sector.

description: The milk sector in Ukraine has been facing several acute problems. This article analyses the economic aspects of production, as well as consumption of milk and dairy products in Ukraine. The purpose of the study is to analyze the state of production, as well as the consumption of milk and dairy products in Ukraine, to identify the factors influencing the production, marketing and consumption of these products. The optimal amounts of milk and dairy products production are determined, which will enable to meet the needs of the population according to the rules of rational nutrition. The article attracts attention to the problems of the dairy products complex of Ukraine, which results in insufficient consumption of the necessary products by the majority of the population of the country, which leads to inconsistencies between production, solvency and the needs of the population. The factors which affect the supply and demand for milk and dairy products in Ukraine are determined. The development of the dairy products complex in Ukraine requires intensification of branches of dairy cattle breeding, the development of the forage base, optimization of the relations between farms with the processing industry of the agroindustrial complex, the improvement of the price mechanism for the formation of the milk resources market and the improvement of the quality and range of dairy products.

description: We analyze the complex impact of the local magnetic spin texture on the transverse Hall-type voltage in device structures utilized to measure magnetoresistance effects. We find a highly localized and asymmetric magnetic sensitivity in the eight-terminal geometries that are frequently used in current-induced switching experiments, for instance to probe antiferromagnetic materials. Using current-induced switching of antiferromagnetic NiO/Pt as an example, we estimate the change in the spin Hall magnetoresistance signal associated with switching events based on the domain switching patterns observed via direct imaging. This estimate correlates with the actual electrical data after subtraction of a non-magnetic contribution. Here, the consistency of the correlation across three measurement geometries with fundamentally different switching patterns strongly indicates a magnetic origin of the measured and analyzed electrical signals.

description: Using plasma-enhanced chemical vapor deposition (PECVD) with Acetylene and Ammoniac on Pd-specimens Carbon nanotubes (CNT) could be produced successfully. Two different devices are compared and the conditions for best growth conditions are explained. The detailed analysis of electron diffraction pattern obtained by transmissions electron microscopy (TEM) of as-grown specimen showed an expansion of the Pd lattice, which can be explained by the formation of fcc-PdHx for x=0...1. For x=1..2 the first investigation of hexagonal -PdH2 is reported, which lattice spacing is independent on the hydrogen content. The amount of fcc-PdH and hcp-PdH2 increases when the specimens are treated subsequently with Hydrogen. A growth model is provided.

description: By using direct numerical simulations of up to a record resolution of 512x512x32768 grid points we discover the existence of a new metastable out-of-equilibrium state in rotating turbulence. We scan the phase space by varying both the rotation rate (proportional to the inverse of the Rossby number, $Ro$) and the dimensionless aspect ratio, $λ=H/L$, where $L$ and $H$ are the sizes of the domain perpendicular and parallel to the direction of rotation, respectively. We show the existence of three turbulent phases. For small $Ro$ but finite $λ$, we have a split cascade where the injected energy is transferred to both large and small scales. For large $λ$ and finite $Ro$ there is no inverse cascade and the energy is transferred forward in Fourier space only. Surprisingly, between these two regimes, a third phase is observed as reported here for the first time. Consequently, for certain intervals of $Ro$ and $λ$, energy is no longer accumulated at arbitrarily large scales, rather it stops at some characteristic intermediate length-scales from where it is then redistributed forward in Fourier space, leading to a flux-loop mechanism where the flow is out of equilibrium with vanishing net flux, and non-vanishing heterochiral and homochiral sub-fluxes. The system is further characterized by the presence of metastability and critical slowing down, explaining why previous experiments and numerical simulations were not able to detect this phenomenon, requiring extremely long observation time and huge computational resources.

description: We describe explicit open books on arbitrary plumbings of oriented circle bundles over closed oriented surfaces. We show that, for a non-positive plumbing, the open book we construct is horizontal and the corresponding compatible contact structure is also horizontal and Stein fillable. In particular, we describe horizontal open books on some Seifert fibered 3--manifolds. As another application we describe horizontal open books isomorphic to Milnor open books for some complex surface singularities. Moreover we give examples of tight contact 3--manifolds supported by planar open books. As a consequence the Weinstein conjecture holds for these tight contact structures.

The age of the oldest Open Clusters

description: We determine ages of 71 old Open Clusters by a two-step method: we use main-squence fitting to 10 selected clusters, in order to obtain their distances, and derive their ages from comparison with our own isochrones used before for Globular Clusters. We then calibrate the morphological age indicator delta(V), which can be obtained for all remaining clusters, in terms of age and metallicity. Particular care is taken to ensure consistency in the whole procedure. The resulting Open Cluster ages connect well to our previous Globular Cluster results. From the Open Cluster sample, as well as from the combined sample, questions regarding the formation process of Galactic components are addressed. The age of the oldest open clusters (NGC6791 and Be17) is of the order of 10 Gyr. We determine a delay by 2.0+-1.5 Gyr between the start of the halo and thin disk formation, whereas thin and thick disk started to form approximately at the same time. We do not find any significant age-metallicity relationship for the open cluster sample. The cumulative age distribution of the whole open cluster sample shows a moderately significant (~2sigma level) departure from the predictions for an exponentially declining dissolution rate with timescale of 2.5 Gyr. The cumulative age distribution does not show any trend with galactocentric distance, but the clusters with larger height to the Galactic plane have an excess of objects between 2-4 and 6 Gyr with respect to their counterpart closer to the plane of the Galaxy.

description: We study the influence of many-body interactions on the transport characteristics of a novel device structure, consisting of a pair of quantum wires that are coupled to each other by means of a quantum dot. Under conditions where a local magnetic moment is formed in one of the wires, we show that tunnel coupling to the other gives rise to an associated peak in its density of states, which can be detected directly in a conductance measurement. Our theory is therefore able to account for the key observations in the recent study of T. Morimoto et al. [Appl. Phys. Lett. {\bf 82}, 3952 (2003)], and demonstrates that coupled quantum wires may be used as a system for the detection of local magnetic-moment formation.

description: We study DBI-type effective theory of an unstable D3-brane in the background manifold R^{1,1} x M_2 where M_2 is an arbitrary two-dimensional manifold. We obtain an exact tubular D2-brane solution of arbitrary cross sectional shape by employing 1/cosh tachyon potential. When M_2=S^2, the solution is embedded in the background geometry R^{1,3} x S^2 of Salam-Sezgin model. This tachyon potential shows a unique property that an array of tachyon soliton solutions has a fixed period which is independent of integration constants of the equations of motion. The thin BPS limit of the configurations leads to supertubes of arbitrary cross sectional shapes.

Generalization of the Franck-Condon model for phonon excitations by resonant inelastic X-ray scattering

description: Resonant inelastic X-ray scattering (RIXS) is increasingly used to quantify vibronic interactions in materials. In the case of periodic systems, this is most often done through fitting experimental results to a parameterized, but exact analytical solution of a simple Holstein Hamiltonian that consists of a single electronic level coupled linearly to a single Einstein vibrational mode. Working within this standard framework, we consider the impact of minor generalizations of this model, namely, introducing a second Einstein oscillator, and allowing the curvature of the excited-state potential energy surface to differ from that of the ground-state potential energy surface. We find that dynamics occurring in the RIXS intermediate (excited) state considerably alter the quantitative interpretation of the spectral features observed in the RIXS final state. This complicates the use of the single mode model when multiple phonon modes are active. Our generalized model may in principle by substituted in this case, though we find that accurate quantitative results rely on knowledge of the excited-state potential energy surface, though this typically is not known.
