The minimal U(1)' extension of the MSSM

description: Motivated by the apparent need for extending the MSSM and perhaps mitigating naturalness problems associated with the $μ$ parameter and fine-tuning of the soft masses, we augment the MSSM spectrum by a SM gauge singlet chiral superfield, and enlarge the gauge structure by an additional U(1)' invariance, so that the gauge and Higgs sectors are relatively secluded. One crucial aspect of U(1)' models is the existence of anomalies, cancellation of which may require the inclusion of exotic matter which in turn disrupts the unification of the gauge couplings. In this work we pursue the question of canceling the anomalies with a minimal matter spectrum and no exotics. This can indeed be realized provided that U(1)' charges are family-dependent and the soft-breaking sector includes non-holomorphic operators for generating the fermion masses. We provide the most general solutions for U(1)' charges by taking into account all constraints from gauge invariance and anomaly cancellation. We analyze various laboratory and astrophysical bounds ranging from fermion masses to relic density, for an illustrative set of parameters. The U(1)' charges admit patterns of values for which family nonuniversality resides solely in the lepton sector, though this does not generate leptonic FCNCs due to the U(1)' gauge invariance.

Incomplete Spinal Cord Injury: Incomplete Support
Creators: name: Parkinson, Melanie
Publisher: name: University of British Columbia
Year: 2009

description: Incomplete spinal cord injury (ISCI) refers to a spinal cord injury (SCI) leaving a person with considerable sensation and function below the site of the injury. Impairments caused by the injury can often be invisible, and people who sustain an ISC I yet retain the ability to walk face unique psychosocial issues. With a view to documenting their experience and the implications for support services, I conducted a focus group study with six adults who have sustained an ISCI, and who can walk. The findings of this qualitative study reveal that the impairments associated with ISCI are largely misunderstood by society in general, and by those who shape services designed to support people with disabilities. Lack of understanding can lead to denial of appropriate resources that would facilitate achievement of a satisfactory quality of life. This study is based in structural theory and aims to shed light on the broad socio-political context.

description: Antimicrobial drugs are fed to hogs at sub-therapeutic levels to prevent disease and promote growth. However, there is concern that the presence of antimicrobial drugs in hog feed is a factor promoting the development of antimicrobial drug-resistant bacteria. This study describes the extent to which antibiotics are used in hog production and how this changed between 2004 and 2009. This study also uses a sample-selection model to examine the impact that use has on the productivity of U.S. hog operations. Using hog producer data from 2004, the analysis did not find a relationship between productivity and sub-therapeutic antibiotics fed during finishing, but productivity was significantly improved when fed to nursery pigs. These results are being evaluated using similar data from 2009.

description: Smart contracts are computer programs that are deployed on the blockchain and can then be executed. Fees in form of gas have to be paid for deploying a smart contract on the blockchain, depending on the size of the byte code. Additional fees have to be paid, whenever a function of a smart contract is executed, depending on the needed computational steps and required storage space. On the Ethereum blockchain, millions of USD are paid in form of gas fees every single day. Since gas cost can increase if a contract is not well-implemented, there is a lot of incentive to reduce these gas cost in order to save money. We identified 19 optimization strategies from the field of software engineering, which can be applied to Solidity smart contracts in order to reduce the required gas cost. To show how these rules can be used to optimize smart contracts, we developed a prototype. The prototype detects rule violations from 9 of these rules and in addition automatically optimizes 6 of them. The prototype analyzed 3,018 verified open source smart contracts from etherscan.io. We found 471 rule violations in our test data set spread across 204 different contract files. That means, roundabout 6.8% of the data set violated at least one of the rules. We deployed the automatically optimized contracts in a test environment before and after the optimization, to compare the gas usage. We were on average able to save 1,213 gas for deploying an optimized contract version compared to the initial one. For calling an optimized function once, we were able to save on average 123 gas, compared to the initial function call.

description: I have demonstrated the existence of a tight correlation between the mass, radius, central density, and pressure of maximum-mass neutron stars modeled using diverse baryonic equations of state. A possible explanation for these correlations is provided. Simple analytic forms of such correlations are suggested and compared with observational constraints on the maximum mass of neutron stars and their radii. This gives a valuable tool to constrain maximum pressure and density that could be reached in stable neutron stars, assuming their equation of state is baryonic.

description: A new urgency is emerging around nuclear power development and this urgency is accentuated by the post-tsunami events at the Fukushima Daiichi nuclear power plant in Japan. This urgency extends beyond these dramatic events in Japan, however, to many other regions of the world and situations where nuclear power development is receiving renewed attention as an alternative to carbon-based energy sources. As a contribution to the growing public debate about nuclear power development, this paper offers a set of insights into the social and ethical aspects of nuclear power development by drawing from published literature in the humanities and social sciences. We offer insights into public risk perception of nuclear power at individual and national levels, the siting of nuclear waste repositories, the changing policy context for nuclear power development, social movements, and the challenges of risk management at the institutional level. We also pay special attention to the ethical aspects of nuclear power with attention to principles such as means and ends, use value and intrinsic value, private goods and public goods, harm, and equity considerations. Finally, we provide recommendations for institutional design and performance in nuclear power design and management.

description: We describe a means of rejecting a null hypothesis concerning observed, but not deliberately manipulated, variables of the form H0: A -/-> B in favor of an alternative hypothesis HA: A --> B, even given the possibility of causally related unobserved variables. Rejection of such an H0 relies on the availability of two observed and appropriately related instrumental variables. While the researcher will have limited control over the confidence level in this test, simulation results suggest that type I errors occur with a probability of less than 0.15 (often substantially less) across a wide range of circumstances. The power of the test is limited if there are but few observations available and the strength of correspondence among the variables is weak. We demonstrate the method by testing a hypothesis with critically important policy implications relating to a possible cause of childhood malnourishment.

description: The ability to image through turbid media such as organic tissues, is a highly attractive prospect for biological and medical imaging. This is challenging however, due to the highly scattering properties of tissues which scramble the image information. The earliest photons that arrive at the detector are often associated with ballistic transmission, whilst the later photons are associated with complex paths due to multiple independent scattering events and are therefore typically considered to be detrimental to the final image formation process. In this work we report on the importance of these highly diffuse, "late" photons for computational time-of-flight diffuse optical imaging. In thick scattering materials, >80 transport mean free paths, we provide evidence that including late photons in the inverse retrieval enhances the image reconstruction quality. We also show that the late photons alone have sufficient information to retrieve images of a similar quality to early photon gated data. This result emphasises the importance in the strongly diffusive regime discussed here, of fully time-resolved imaging techniques.

We show in very simple algebraic terms that the solutions of the recursively defined formulae for the Birkhoff factorization of regularized Hopf algebra characters, i.e. Feynman rules, naturally give a non-commutative generalization of the well-known Spitzer's identity. The underlying abstract algebraic structure is analyzed in terms of complete filtered Rota-Baxter algebras.

In order to examine tail structures of ALS, we apply the multifractal analysis only for the tail region of ALS and compare with the whole structure. It is found that the amplitude distribution in the tail region of ALS is multifractal and values of exponents characterizing multifractality are the same with those for typical multifractal wavefunctions in this universality class.

description: The utility maximization problem of a grain producer is formulated and solved numerically under prospect theory as an alternative to expected utility theory. Conventional theory posits that the optimal hedging position of a producer is not affected solely due to changes in the level of futures prices. However, a strong degree of positive correlation is apparent in the data. Our results show that with prospect theory serving as the underlying behavioral framework, the optimal hedge of a producer is affected by changes in futures price levels. The implications of this price-induced hedging behavior on spot prices and volatility are subsequently considered.

description: In recent years, the prospects of performing fundamental and applied studies at the next-generation high-intensity laser facilities have greatly stimulated the interest in performing large-scale simulations of laser interaction with matter with the account for quantum electrodynamics (QED) processes such as emission of high energy photons and decay of such photons into electron-positron pairs. These processes can be modeled via probabilistic routines that include frequent computation of synchrotron functions and can constitute significant computational demands within accordingly extended Particle-in-Cell (QED-PIC) algorithms. In this regard, the optimization of these routines is of great interest. In this paper, we propose and describe two modifications. First, we derive a more accurate upper-bound estimate for the rate of QED events and use it to arrange local sub-stepping of the global time step in a significantly more efficient way than done previously. Second, we present a new high-performance implementation of synchrotron functions. Our optimizations made it possible to speed up the computations by a factor of up to 13.7 depending on the problem. Our implementation is integrated into the PICADOR and Hi-Chi codes, the latter of which is distributed publicly (https://github.com/hi-chi/pyHiChi).

description: We report the precise optical and X-ray localization of the 3.2 ms accretion-powered X-ray pulsar XTE J1814-338 with data from the Chandra X-Ray Observatory as well as optical observations conducted during the 2003 June discovery outburst. Optical imaging of the field during the outburst of this soft X-ray transient reveals an R = 18 star at the X-ray position. This star is absent (R > 20) from an archival 1989 image of the field and brightened during the 2003 outburst, and we therefore identify it as the optical counterpart of XTE J1814-338. The best source position derived from optical astrometry is R.A. = 18h13m39.s04, Dec.= -33d46m22.3s (J2000). The featureless X-ray spectrum of the pulsar in outburst is best fit by an absorbed power-law (with photon index = 1.41 +- 0.06) plus blackbody (with kT = 0.95 +- 0.13 keV) model, where the blackbody component contributes approximately 10% of the source flux. The optical broad-band spectrum shows evidence for an excess of infrared emission with respect to an X-ray heated accretion disk model, suggesting a significant contribution from the secondary or from a synchrotron-emitting region. A follow-up observation performed when XTE J1814-338 was in quiescence reveals no counterpart to a limiting magnitude of R = 23.3. This suggests that the secondary is an M3 V or later-type star, and therefore very unlikely to be responsible for the soft excess, making synchroton emission a more reasonable candidate.

Quantum-Enhanced Simulation-Based Optimization

description: In this paper, we introduce a quantum-enhanced algorithm for simulation-based optimization. Simulation-based optimization seeks to optimize an objective function that is computationally expensive to evaluate exactly, and thus, is approximated via simulation. Quantum Amplitude Estimation (QAE) can achieve a quadratic speed-up over classical Monte Carlo simulation. Hence, in many cases, it can achieve a speed-up for simulation-based optimization as well. Combining QAE with ideas from quantum optimization, we show how this can be used not only for continuous but also for discrete optimization problems. Furthermore, the algorithm is demonstrated on illustrative problems such as portfolio optimization with a Value at Risk constraint and inventory management.

description: Viele interessante industrielle und natürliche Gase haben starke Absorptionslinien im mittleren Wellenlängeninfrarotbereich, wo die Vertical External Cavity Surface Emitting Lasers (VECSELs) mit IV-VI Halbleitern auf Basis von Bleichalkogeniden realisiert worden sind. Camlin Technologies CH hat schon VECSELs als Pulslaser für Anwendungen in der Gas Detektion erfolgreich kommerzialisiert und der nächste Schritt ist die Entwicklung eines VECSELs als Dauerstrichlaser (CW). Um höhere Ausgangsleistung und längere Impulslängen für den Dauerstrichbetrieb zu erreichen, ist es notwendig den Wärmefluss der jetzigen Laser besser zu verstehen. Das Hauptziel dieser Arbeit ist die Erstellung eines COMSOL Multiphysics Modells, um die Wärmeprofile dieser Laser unter verschiedenen Einstellungen zu simulieren. Dieses Modell hilft, elektronische und optische Verluste zu verstehen, und ermöglicht die Entdeckung einer effektiven Wärmeabfuhr. In dieser Arbeit wird auch eine Reihe von Photolumineszenzmessungen mit verschiedenen Laserchips durchgeführt und diese mit verarbeiteten Simulationsergebnissen verglichen, um die unbekannten, aber notwendigen Simulationsparameter zu erhalten.
description: Many important industrial and natural gases have strong absorption lines in the mid-wavelength infrared range, where the Vertical External Cavity Surface Emitting Lasers (VECSELs) have been realized with IV-VI semiconductors based on lead chalcogenides. Camlin Technologies CH has already commercialized VECSELs in pulsed mode for gas detection applications and the next step is to develop VECSELs for continuous wave (CW) operation. A better understanding of the current laser's heat flux is necessary in order to achieve higher output power and longer pulse lengths towards CW operation. The main goal of this thesis is the creation of a COMSOL Multiphysics model to simulate the heat profiles of these lasers under different settings. This model helps to understand electronic and optical losses and allows the discovery of effective heat removal. A series of photoluminescence measurements with different laser chips will also be done within this thesis for comparison with post-processed simulation results to obtain the unknown but necessary simulation parameters.

description: O trabalho tem sua problemática centrada na questão da qualidade da educação superior. O texto estabelece uma reflexão sobre o processo de implantação das políticas de avaliação da educação superior no Brasil, principalmente as que envolvem a questão da qualidade dos cursos e das instituições. Orienta-se pela seguinte questão: quão efetivas têm sido as políticas públicas de avaliação da qualidade da educação superior no Brasil para a promoção da formação humana? A investigação se desenvolve a partir do conceito de campo de Pierre Bourdieu, por isso busca identificar os principais agentes que instituem a lógica para a definição de qualidade para a política pública de educação. Demarca a constituição do campo da educação superior apontando o nascimento dos primeiros cursos e principais instituições. Realiza uma descrição histórica das políticas de avaliação da educação superior no Brasil. Apresenta os relatórios dos grupos, programas e comissão para a promoção de políticas para a educação superior, notadamente GTRU (Grupo de Trabalho da Reforma Universitária), PARU (Programa de Avaliação e Reforma Universitária), CNRES (Comissão Nacional para a Reforma do Ensino Superior), GERES (Grupo Executivo para a Reformulação da Reforma Universitária), PAIUB (Programa de Avaliação Institucional das Universidades Brasileiras), ENC (Exame Nacional de Cursos), CEA (Comissão Especial de Avaliação da Educação Superior) e finalmente o SINAES (Sistema Nacional de Avaliação da Educação Superior). Analisa o ENADE (Exame Nacional de Desempenho dos Estudantes) e aponta o surgimento de indicadores de qualidade dos cursos de graduação: ENADE, IDD (Indicador de Diferença entre os Desempenhos Observados e Esperados) e CPC (Conceito Preliminar de Curso). Faz ponderação do resultado global das avaliações dos cursos de nove edições do ENADE, que correspondem a 3 (três) ciclos de 3 (três) anos, efetuados entre 2004 a 2012. Especialmente sobre o terceiro ciclo (2010-2012) faz um estudo do desempenho no ENADE das IES e dos cursos por categoria administrativa: pública e privada e organização acadêmica: faculdade, centro-universitário e universidade. Conclui a análise destacando a permanência dos aspectos que compreendem uma abordagem conservadora de avaliação da qualidade da educação superior em detrimento de uma abordagem transformadora. Ademais, mostra as principais alterações entre a proposta de política de avaliação do CEA e a política avaliativa implantada pelo SINAES que inviabilizaram a execução de uma avaliação voltada para a uma prática pedagógica transformadora por se embasar em critérios de regulação e controle.

description: A Moebius covariant net of von Neumann algebras on S^1 is diffeomorphism covariant if its Moebius symmetry extends to diffeomorphism symmetry. We prove that in case the net is either a Virasoro net or any at least 4-regular net such an extension is unique: the local algebras together with the Moebius symmetry (equivalently: the local algebras together with the vacuum vector) completely determine it. We draw the two following conclusions for such theories. (1) The value of the central charge c is an invariant and hence the Virasoro nets for different values of c are not isomorphic as Moebius covariant nets. (2) A vacuum preserving internal symmetry always commutes with the diffeomorphism symmetries. We further use our result to give a large class of new examples of nets (even strongly additive ones), which are not diffeomorphism covariant; i.e. which do not admit an extension of the symmetry to Diff^+(S^1).

Divergent mechanisms utilized by SOCS3 to mediate IL-10 inhibition of TNF-a and nitric oxide production by macrophages

Publisher: name: University of British Columbia

description: The cytokine, interleukin-10 (IL-10), inhibits activation o f macrophages by activators such as lipopolysacchride (LPS). However the mechanism by which IL-10 interferes with LPS signalling is still unclear. One well-characterized signalling pathway activated b y IL-10 is that of Stat3 (Signal transducer and activator o f transcription), which is essential for the antiproliferative and anti-inflammatory actions of IL-10 on macrophages. In our search for IL-10- induced, Stat3-regulated genes, we found a candidate belonging to SOCS (suppressor of cytokine signalling) family of negative regulators of cytokine signalling. Using mutant IL-10 receptor and dominant negative Stat3, we show that IL-10 induces SOCS3 message and protein in a Stat3-dependent manner. However mere expression o f SOCS3 protein in macrophages was not sufficient to inhibit TNF-α protein production in response to LPS, suggesting that additional IL-10-induced signals are required. And indeed we find IL-10 stimulation induces phosphorylation of tyrosine 204 o f SOCS3 protein. In order to determine the role o f SOCS3 in IL-10 inhibition of macrophage activation, we derived cell lines from SOCS3⁻[sup /]⁻ and SOCS3⁺[sup /]⁻ mice. SOCS3⁻[sup /]⁻ macrophages respond to LPS in a manner similar to wild-type cells, but IL-10 is less effective in inhibiting LPS-induced TNF-α and NO production in the SOCS3⁻[sup /]⁻ cells as compared to SOCS3⁺[sup /]⁻ macrophages. Reconstitution of SOCS3⁻[sup /]⁻ cells with a wild-type SOCS3 cDNA restored IL-10 responsiveness. In order to determine which SOCS3 domain is important in IL-10 signalling, SOCS3⁻[sup /]⁻ macrophages were reconstituted with various SOCS3 domain mutants. IL-10 required all domains of SOCS3 protein for the inhibition of TNF-α protein expression. However, for inhibition of TNF-α mRNA expression, IL-10 does not seem to require the KIR domain of SOCS3 protein. In contrast, only the two tyrosine residues, 204 and 221, located in the SOCS-box domain are required for IL-10 inhibition of LPS-induced iNOS protein expression and subsequent NO production. These studies demonstrate the importance of SOCS3 protein in the anti-inflammatory action of IL-10 and that inhibition of NO and TNF-α by IL-10 depends on different domains of SOCS3. Characterization of SOCS3 signalling domains and its immediate downstream targets will allow development of therapeutic strategies, which replicate the beneficial anti- inflammatory action of IL-10.

description: Solar neutrino flares astronomy is at the edge of its discover. High energy flare particles (protons, alpha) whose self scattering within the solar corona is source of a rich prompt charged pions are also source of sharp solar neutrino "burst" (at tens-hundred MeV) produced by their pion-muon primary decay in flight. This brief (minute) solar neutrino "burst" at largest peak overcome by four-five order of magnitude the steady atmospheric neutrino noise at the Earth. Later on, solar flare particles hitting the terrestrial atmosphere may marginally increase the atmospheric neutrino flux without relevant consequences. Largest prompt "burst" solar neutrino flare may be detected in present or better in future largest neutrino underground neutrino detectors. Our estimate for the recent and exceptional October - November 2003 solar flares gives a number of events above or just near unity for Super-Kamiokande. The neutrino spectra may reflect in a subtle way the neutrino flavour mixing in flight. A surprising tau appearance may even occur for a hard ({E}_{nu}_{mu}--> {E}_{nu}_{tau} > 4 GeV) flare spectra. A comparison of the solar neutrino flare (at their birth place on Sun and after oscillation on the arrival on the Earth) with other neutrino foreground is here described and it offer an independent road map to disentangle the neutrino flavour puzzles and its secret flavour mixing angles .

Geometrical constraints on the tangling of bacterial flagellar filaments

description: Many species of bacteria swim through viscous environments by rotating multiple helical flagella. The filaments gather behind the cell body and form a close helical bundle, which propels the cell forward during a "run". The filaments inside the bundle cannot be continuously actuated, nor can they easily unbundle, if they are tangled around one another. The fact that bacteria can passively form coherent bundles, i.e. bundles which do not contain tangled pairs of filaments, may appear surprising given that flagella are actuated by uncoordinated motors. In this article, we establish the theoretical conditions under which a pair of rigid helical filaments can form a tangled bundle, and we compare these constraints with experimental data collected from the literature. Our results suggest that bacterial flagella are too straight and too far apart to form tangled bundles based on their intrinsic, undeformed geometry alone. This makes the formation of coherent bundles more robust against the passive nature of the bundling process, where the position of individual filaments cannot be controlled.

description: Agricultural biofuels require the use of scarce land, and this land has opportunity cost. We explore the objective function of a social planner who includes a land constraint in the optimization decision to minimize environmental cost. The results show that emissions should be measured on a per acre basis. Conventional agricultural life cycle assessments for biofuels report carbon emissions on a per gallon basis, thereby ignoring the implications of land scarcity and implicitly assuming an infinite supply of the inputs needed for production. Switchgrass and corn are then modeled as competing alternatives to show how the inclusion of a land constraint can influence life cycle rankings and alter policy conclusions.

description: Motion of vortices in two-dimensional superfluids in the classical limit is studied by solving the Gross-Pitaevskii equation numerically on a uniform lattice. We find that, in the presence of a superflow directed along one of the main lattice periods, vortices move with the superflow on fine lattices but perpendicular to it on coarse ones. We interpret this result as a transition from the full Magnus force in the Galilean-invariant limit to vanishing effective Magnus force in a discrete system, in agreement with the existing experiments on vortex motion in Josephson junction arrays.
