description: No abstracts are to be cited without prior reference to the author.The seasonal zooplankton dynamics of marine systems are characterized by a few key players. In the North Sea, one of these species is Pseudocalanus elongatus, a calanoid copepod displaying different seasonal dynamics in northern and southern areas of that ecosystem. These dynamics are probably best captured by models using an explicit representation of a structured population as opposed to merely a “bulk” zooplankton carbon formulation. The present study describes efforts to couple a stage-structure population model constructed for P. elongatus to a three-dimensional ecosystem model (ECOHAM4). The copepod model includes 10 state variables within five life stages, one each for abundance and biomass. The dynamic trophic interactions in the ecosystem model include functional groups for fast- and slow-sinking detritus, bacteria, diatoms, flagellates, and micro- and mesozooplankton. Simulations were run for the Northwestern European Continental Shelf (NERC) using realistic meteorological and hydrographic conditions for 2003–2004 to examine simulated seasonal zooplankton population dynamics compared with in situ data for southern (GLOBEC observations) and northern (FLEX observations) areas. In the northern area, two peaks in zooplankton biomass were predicted with a lag between bulk and structured zooplankton biomass maxima in spring and lower biomass levels for both zooplankton types during summer. Compared with the northern area, the zooplankton biomass in the southern area peaked earlier in the season. In both areas, productivity of P. elongates was controlled more by food availability than temperature. Model parameterizations and trade-offs between zooplankton estimates obtained using bulk ecosystem and structure–population models are discussed.

description: Within the theory of the ghost-free bigravity, we present the most general cosmological solution for which the physical metric is homogeneous and isotropic, while the second metric is inhomogeneous. The solution includes a matter source and exists for any values of the theory parameters. The physical metric describes a universe with the late time acceleration due to the effective cosmological term mimicked by the graviton mass. When perturbed, this universe should rest approximately homogeneous and isotropic in space regions small compared to the graviton Compton length. In the limit where the massless graviton decouples, the solution fulfills the equations of the ghost-free massive gravity.

description: No abstracts are to be cited without prior reference to the author.The stocks of many marine fishes comprise several spawning components that differ with respect to life history traits. Recent field studies indicate that the maturity and fecundity – size relationships of both cod and haddock differ among putative subpopulations in the North Sea. In this paper we report on how these differences in reproductive characteristics have developed over the last decades, in terms of the change in probabilistic maturation reaction norms and weight specific fecundity. Subpopulations inhabiting the most heavily depleted and climatically variable region have undergone the largest declines in size and age at maturation, with cod and haddock from the north west inshore region now maturing at much smaller sizes and at a year younger than those from the north east region. Maturation differences between these sub-populations persisted when juveniles were raised under a common environment, suggesting that present differences were not solely reflective of local environment. Nevertheless, warming during the summer maturation decision phase may also have contributed to the rapid decline in maturation reaction norms. Fecundity at size has also increased in the inshore north west North Sea in haddock. Over the same time, somatic condition and post-maturation growth of these haddock has declined. Take together these observations are consistent with a fisheries induced adaptive change in reproductive effort. Further, this study demonstrates that a failure to account for substock structuring can lead to erroneous conclusions about the magnitude of such changes within a stock.

description: A widely used method for estimating Casimir interactions [H. B. G. Casimir, Proc. K. Ned. Akad. Wet. 51, 793 (1948)] between gently curved material surfaces at short distances is the proximity force approximation (PFA). While this approximation is asymptotically exact at vanishing separations, quantifying corrections to PFA has been notoriously difficult. Here we use a derivative expansion to compute the leading curvature correction to PFA for metals (gold) and insulators (SiO$_2$) at room temperature. We derive an explicit expression for the amplitude $\hatθ_1$ of the PFA correction to the force gradient for axially symmetric surfaces. In the non-retarded limit, the corrections to the Casimir free energy are found to scale logarithmically with distance. For gold, $\hatθ_1$ has an unusually large temperature dependence.

description: We identify a special information-theoretic property of quantum field theories with holographic duals: the mutual informations among arbitrary disjoint spatial regions A,B,C obey the inequality I(A:BC) >= I(A:B)+I(A:C), provided entanglement entropies are given by the Ryu-Takayanagi formula. Inequalities of this type are known as monogamy relations and are characteristic of measures of quantum entanglement. This suggests that correlations in holographic theories arise primarily from entanglement rather than classical correlations. We also show that the Ryu-Takayanagi formula is consistent with all known general inequalities obeyed by the entanglement entropy, including an infinite set recently discovered by Cadney, Linden, and Winter; this constitutes strong evidence in favour of its validity.

description: No abstracts are to be cited without prior reference to the author.Trait evolution over time periods spanning generations, not millennium, is increasingly observed to be above the natural baseline in populations experiencing human-induced perturbations. We investigated the relative speed of trait change by comparing rates of evolution in haldanes and darwins for length (or weight) at maturation from probabilistic maturation reaction norm midpoints for fish stocks from the Northwest Atlantic, Northeast Arctic and Barents Sea, and the North Sea. For stocks that had a moratorium enacting during the time period, rates were estimated for pre- and post-moratorium. Absolute rates in haldanes for 17 stocks ranged from 0.02–1.9 and from 0.5–153 in kdarwins (103 darwins) for 21 stocks. The North Sea and northwest Atlantic (pre-moratorium) cod stocks had some of the fastest rates of change (in haldanes), while post-moratorium northwest Atlantic and Icelandic cod stocks had the slowest rates. North sea sole and plaice haldane rates also tended to be slower than the average rate. When comparing rates in darwins, all stocks in the North Sea and Grand Banks, and cod stocks in the Gulf of Maine and 2J3KLNOPs (pre-moratorium time series) experienced some of the fastest evolutionary rates of change. Stating whether fisheriesinduced evolution is fast or slow has limited ecological meaning, and the focus should now be towards determining whether the rate of fisheries-induced evolution is fast enough to permanently alter ecosystem dynamics. The next stage should be to investigate the effect of these relatively fast rates of phenotypic change in terms of fisheries yields and sustainability
Novel phase in SU(3) lattice gauge theory with 12 light fermions

description: We study the phase structure of SU(3) lattice gauge theory with Nf=12 staggered fermions in the fundamental representation, for both zero and finite temperature at strong gauge couplings. For small fermion masses we find two transitions at finite temperature that converge to two well-separated bulk phase transitions. The phase between the two transitions appears to be a novel phase. We identify order parameters showing that the single-site shift symmetry of staggered fermions is spontaneously broken in this phase. We investigate the eigenvalue spectrum of the Dirac operator, the static potential and the meson spectrum, which collectively establish that this novel phase is confining but chirally symmetric. The phase is bordered by first-order phase transitions, and since we find the same phase structure with Nf=8 fermions, we argue that the novel phase is most likely a strong-coupling lattice artifact, the existence of which does not imply IR conformality.

description: No abstracts are to be cited without prior reference to the author.A central part of an impact assessment of the evolutionary effects of fishing is a calculation of the expected rates of fishing induced by current fishing practice and an evaluation of how alternative fishing patterns may reduce evolutionary impacts of fishing. Here a general size-based framework for modeling the demography of fish based on size-based prescriptions of natural mortality, growth, and fishing is presented. Life history theory is used to reduce the necessary parameter set by utilizing relations between parameters making the framework particularly well suited for data-poor situations where only the size at maturation or the asymptotic size is known. The framework is applied to perform the modeling part of an evolutionary impact assessment using basic quantitative genetics to calculated expected rates of evolution on size at maturation, growth rate, and investment in gonads. A sensitivity analysis of the parameter values is performed, and calculations of how different fishing patterns influences the results are presented.

description: No abstracts are to be cited without prior reference to the author.Fish in many exploited stocks grow faster and mature earlier at either larger or smaller sizes in comparison to pre-exploitation periods. These changes can be driven by both genetic and phenotypic responses. At the same time, these stocks may adjust to other changes of the environment such as increasing/decreasing overall productivity or changes in temperature. Using a model of planktivorous fish with annual spawning and size- and density-dependent individual growth, we ask if the interplay of environmental change and fishing pressure could lead to stabilizing, disruptive or directional selection on age and size at maturation in the stock. This question is particularly relevant for habitats exposed to significant directional change in the environment, the prime example being many man-made inland reservoirs.

description: The electronic structure of Bernal-stacked graphite subject to tilted magnetic fields is studied theoretically. The minimal nearest-neighbor tight-binding model with the Peierls substitution is employed to describe the structure of Landau levels. We show that while the orbital effect of the in-plane component of the magnetic field is negligible for massive Dirac fermions in the vicinity of the K point of the graphite Brillouin zone, at the H point it leads to the experimentally observable splitting of Landau levels, which grows approximately linearly with the in-plane field intensity.

description: Based on density-functional theory calculations, we report a detailed study of the single-molecule charge-transport properties for a series of recently synthesized biphenyl-dithiol molecules [D. Vonlanthen et al., Angew. Chem., Int. Ed. 48, 8886 (2009); A. Mishchenko et al., Nano Lett. 10, 156 (2010)]. The torsion angle ϕ between the two phenyl rings, and hence the degree of π conjugation, is controlled by alkyl chains and methyl side groups. We consider three different coordination geometries, namely top-top, bridge-bridge, and hollow-hollow with the terminal sulfur atoms bound to one, two, and three gold surface atoms, respectively. Our calculations show that different coordination geometries give rise to conductances which vary by one order of magnitude for the same molecule. Irrespective of the coordination geometries, the charge transport calculations predict a cos^{2}ϕ dependence of the conductance, which is confirmed by our experimental measurements. We observe that the calculated transmission through biphenyl dithiols is typically dominated by a single transmission eigenchannel formed from π electrons. Only for a single molecule with a completely broken conjugation we find a perfect channel degeneracy for the hollow-hollow-type contact in our theory.

description: In this paper, we will outline computations of quantum sheaf cohomology for deformations of tangent bundles of toric varieties, for those deformations describable as deformations of toric Euler sequences. Quantum sheaf cohomology is a heterotic analogue of quantum cohomology, a quantum deformation of the classical product on sheaf cohomology groups, that computes nonperturbative corrections to analogues of (27*)^3 couplings in heterotic string computations. Previous computations have relied on either physics-based GLSM techniques or computation-intensive brute-force Cech cohomology techniques. This paper describes methods for greatly simplifying mathematical computations, and derives more general results than previously obtainable with GLSM techniques. We will outline recent results (rigorous proofs will appear elsewhere).

Feasibility of Diffraction Radiation for Non-invasive Micron-scale Transverse Beam Size Measurement in Circular Machines
Creators: name: Bobb, Lorraine
Publisher: name: Zenodo
Year: 2016

description: Beam size measurement using diffraction radiation has been investigated in recent years as a non-invasive counterpart to transition radiation monitors. Previous diffraction radiation monitors have been located on linear machines whereby the passage of the charged particle beam through the target aperture is somewhat simplified. For future accelerators, such as the Compact Linear Collider, the use of diffraction radiation monitors would be extended to include both linear and circular sections of the machine where high resolution non-invasive diagnostics are required. In this thesis, the feasibility of diffraction radiation monitors for beam size measurement on circular machines is investigated. The design, installation and operation of such a monitor at CesrTA is described. Beam size measurements of 17.6 µm and 45 µm were obtained using the diffraction radiation monitor at 600 nm wavelength. Measurements were also performed at 400 nm. Angular distributions were compared to two analytical models. Direct imaging of diffraction radiation on the target surface has demonstrated the potential of beam position monitoring as well as allowing for observations of the shadowing effect. Further discussions are made on the performance and limitations of the diffraction radiation monitor due to the complications unique to storage rings.

More specifically, we characterize the achievable DGR of the fixed-power split Han-Kobayashi (HK) approach under these assumptions. Our characterization comes in a closed form and demonstrates that the HK scheme with only a common message is a singular case, which achieves the best DGR among all HK schemes for certain multiplexing gains. Finally, we show that generalized time sharing, with variable rate and power assignments for the common and private messages, does not improve the achievable DGR.

description: The objective of this paper is to determine the level of obscured star formation activity and dust attenuation in a sample of gamma-ray burst (GRB) hosts; and to test the hypothesis that GRB hosts have properties consistent with those of the general star-forming galaxy populations. We present a radio continuum survey of all z<1 GRB hosts in The Optically Unbiased GRB Host (TOUGH) sample supplemented with radio data for all (mostly pre-Swift) GRB-SN hosts discovered before October 2006. We present new radio data for 22 objects and have obtained a detection for three of them (GRB 980425, 021211, 031203; none in the TOUGH sample), increasing the number of radio-detected GRB hosts from two to five. The star formation rate (SFR) for the GRB 021211 host of ~825 Mo yr^-1, the highest ever reported for a GRB host, places it in the category of ultraluminous infrared galaxies. We found that at least 63% of GRB hosts have SFR < 100 Mo yr^-1 and at most 8% can have SFR > 500 Mo yr^-1. For the undetected hosts the mean radio flux (<35 uJy 3sigma) corresponds to an average SFR < 15 Mo yr^-1. Moreover, ~88% of the z<1 GRB hosts have ultraviolet dust attenuation A_UV < 6.7 mag (visual attenuation A_V < 3 mag). Hence we did not find evidence for large dust obscuration in a majority of GRB hosts. Finally, we found that the distributions of SFRs and A_UV of GRB hosts are consistent with those of Lyman break galaxies, Halpha emitters at similar redshifts and of galaxies from cosmological simulations. The similarity of the GRB population with other star-forming galaxies is consistent with the hypothesis that GRBs, a least at z<1, trace a large fraction of all star formation, and are therefore less biased indicators than once thought.

description: Aim: To present and explain the one-way analysis of variance (ANOVA).Background: Quantitative methods and statistical analysis are essential tools in nursing research, as they support researchers testing phenomena/relationships; illustrating their findings clearly and accurately; and providing explanation or generalisation of the phenomenon under investigation. However, issues have been identified within nursing literature, that the usage of statistical tests is not correct as well as the used techniques and reported results. Review methods: Literature research on ANOVA methods and other issues related to statistical analysis in nursing, nurses’ knowledge of statistics and recommendations on how to address these issues are identified.Discussion: The purpose of inferential statistics is presented and one-way ANOVA explained. This is the most popular inferential statistics test, as it is the designated test for the comparison of means (μ) of the research's target groups to identify if the means (μ) are statistically different from the others. The steps in successfully applying the one-way ANOVA are examined by using relevant examples. Recommendations in other statistical tests and measurements, in parallel to one-way ANOVA, are provided. Conclusion: To engage in research and evidence-based practice, nurses need to develop their understanding and knowledge of statistical methods. This article enhances the understanding and application of one-way ANOVAs of student nurses,novice researchers, nurses and those engaged in academic studies.Implications for research/practice: Nurses, student nurses and nurse researchers need to familiarise with statistical terminology and develop their understanding of statistical concepts to support evidence-based quality safe care.

description: The growing interest in carbon-based spintronics has stimulated a number of recent theoretical studies on the RKKY interaction in graphene, based on which the energetically favourable alignment between magnetic moments embedded in this material can be calculated. The general consensus is that the strength of the RKKY interaction in graphene decays as 1/D3 or faster, where D is the separation between magnetic moments. Such an unusually fast decay for a 2-dimensional system suggests that the RKKY interaction may be too short ranged to be experimentally observed in graphene. Here we show in a mathematically transparent form that a far more long ranged interaction arises when the magnetic moments are taken out of their equilibrium positions and set in motion. We not only show that this dynamic version of the RKKY interaction in graphene decays far more slowly but also propose how it can be observed with currently available experimental methods.

description: Pinning of superfluid vortices to magnetic flux tubes in the outer core of a neutron star supports a velocity difference of $\sim 10^5$ \cms\ between the neutron superfluid and the proton-electron fluid as the star spins down. Under the Magnus force that arises on the vortex array, vortices undergo {\em vortex creep} through thermal activation or quantum tunneling. We examine the hydrodynamic stability of this situation. Vortex creep introduces two low-frequency modes, one of which is unstable above a critical wavenumber for any non-zero flow velocity of the neutron superfluid with respect to the charged fluid. For typical pinning parameters of the outer core, the superfluid flow is unstable over wavelengths $λ\lap 10$ m and over timescales of $\sim (λ/{1 m})^{1/2}$ yr down to $\sim 1$ d. The vortex lattice could degenerate into a tangle, and the superfluid flow would become turbulent. We suggest that superfluid turbulence could be responsible for the red timing noise seen in many neutron stars, and find a predicted spectrum that is generally consistent with observations.

description: We discuss a current dynamics on the surface of a 3-dimensional topological insulator induced by magnetization precession of a ferromagnet attached. It is found that the magnetization dynamics generates a direct charge current when the precession axis is within the surface plane. This rectification effect is due to a quantum anomaly and is topologically protected. The robustness of the rectification effect against first-varying exchange field and impurities is confirmed by explicit calculation.

description: Two novel secondary metabolites, including one thujopsene-type sesquiterpene designated thujasutchin N (1) and one norlignan named thujasutchin O (2) were obtained from the ethanolic extract of the stems and roots of Thuja sutchuenensis. Among them, thujasutchin O (2) represents the first example of lignan sharing a unique carbon-reduced skeleton with novel acetal functionality. Their structures were unambiguously determined by means of extensively spectroscopic analysis including UV, IR, HRESIMS, NMR, and single crystal X-ray diffraction. Both of the isolates were evaluated for their in vitro cytotoxic and antibacterial activities.

description: Supersymmetric Unified theories which incorporate a renormalizable Type I seesaw mechanism for small neutrino masses can also provide slow roll inflection point inflation along a flat direction associated with a gauge invariant combination of the Higgs, slepton and right handed sneutrino superfields. Inflationary parameters are related to the Majorana and Dirac couplings responsible for neutrino masses with the scale of inflation set by a right-handed neutrino mass $M_{ν^c} \sim 10^6-10^{12}$ GeV. Tuning of the neutrino Dirac and Majorana superpotential couplings and soft Susy breaking parameters is required to enforce flatness of the inflationary potential. In contrast to previous inflection point inflation models the cubic term is dominantly derived from superpotential couplings rather than soft A-terms. Thus since $M_{ν^c}>>M_{Susy}$ the tuning condition is almost independent of the soft supersymmetry breaking parameters and therefore more stable. The required fine tuning is also less stringent than for Minimal SUSY Standard Model (MSSM) inflation or Dirac neutrino 'A-term" inflation scenarios due to the much larger value of the inflaton mass. Reheating proceeds via `instant preheating' which rapidly dumps all the inflaton energy into a MSSM mode radiation bath giving a high reheat temperature $T_{rh} \approx M_{ν^c}^{3/4}\, 10^{6}$ GeV $\sim 10^{11}- 10^{15} $ GeV. Thus our scenario requires large gravitino mass $> 50 $ TeV to avoid a gravitino problem. The `instant preheating' and Higgs component of the inflaton also imply a `non-thermal' contribution to Leptogenesis due to facilitated production of right handed neutrinos during inflaton decay. We derive the tuning conditions for the scenario to work in the realistic New Minimal Supersymmetric SO(10) GUT and show that they can be satisfied by realistic fits.

description: We perform model-independent statistical analyses of three scenarios accommodating New Physics (NP) in Delta F=2 flavour-changing neutral current amplitudes. In a scenario in which NP in B_d-B_d-bar and B_s-B_s-bar is uncorrelated, we find the parameter point representing the Standard-Model disfavoured by 2.4 standard deviations. However, recent LHCb data on B_s neutral-meson mixing forbid a good accommodation of the D0 data on the semileptonic CP asymmetry A_SL. We introduce a fourth scenario with NP in both M_12^d,s and Gamma_12^d,s, which can accommodate all data. We discuss the viability of this possibility and emphasise the importance of separate measurements of the CP asymmetries in semileptonic B_d and B_s decays. All results have been obtained with the CKMfitter analysis package, featuring the frequentist statistical approach and using Rfit to handle theoretical uncertainties.

One-party deliberations in the U.S. House of Representatives
Creators: name: Bendix, William Claus
Publisher: name: University of British Columbia
Year: 2012

description: Over the last two decades, the majority party in the U.S. House of Representatives has increasingly bypassed committee deliberations and restricted floor debate to prevent the minority party from shaping provisions in bills. In response to this rising partisanship, scholars have attempted to measure the direct influence that parties have on legislative outcomes, often by examining roll-call votes. However, they have done relatively little work on the decline of the committee system and the increasing control that majority-party leaders exert on legislative deliberations. In this project, I examine the way in which increasingly cohesive parties draft bills at the prefloor and floor stages of the legislative process. I ask two questions. First, when does the House majority party seize full control of bill development and exclude the minority party from decision-making? Second, what are the policy consequences of the House majority party barring the minority party from formal legislative deliberations? To answer the first question, I construct multiple measures of legislative actions and procedures for major bills developed between 1983 and 2008 in the House. I find that the majority party controls deliberations when its majority status is threatened or its policy goals face strong opposition. I also find that the majority limits discussion on bills designed to promote its electoral brand. These party-brand bills involve tax and welfare policies as well as moral issues. To answer the second question, I create new measures of bill defects and bill extremity to assess how legislative processes affect bill quality. I determine that truncated deliberation tends to produce substantively problematic legislation. Thus, the findings in this project reinforce concerns over and provide evidence of the negative effects of one-party lawmaking.

description: Present measurements of b->c tau nu and b->u tau nu transitions differ from the standard model predictions of lepton flavor universality by almost 4sigma. We examine new physics interpretations of this anomaly. An effective field theory analysis shows that minimal flavor violating models are not preferred as an explanation, but are also not yet excluded. Allowing for general flavor violation, right-right vector and right-left scalar quark currents are identified as viable candidates. We discuss explicit examples of two Higgs doublet models, leptoquarks as well as quark and lepton compositeness. Finally, implications for LHC searches and future measurements at the (super)B- factories are presented.

description: No abstracts are to be cited without prior reference to the author.Paralytic shellfish poisoning (PSP) is a recurrent and widespread problem in the Gulf of Maine (GOM) caused by the dinoflagellate Alexandrium fundyense. Blooms of this species have been the subject of more than a decade of investigation through the ECOHAB-GOM and GOMTOX research programs. Multiple large-scale field surveys have provided data that were combined with mooring observations, satellite-tracked drifters, and numerical model simulations to document the complex dynamics of A. fundyense blooms within this region. A detailed conceptual model of A. fundyense bloom dynamics and PSP toxicity in the region is summarized here, highlighting where possible the key physiological, behavioral, and environmental or oceanographic factors involved. A numerical model has also been developed and evaluated against cruise observations and other data. The status of those modeling efforts is discussed, including recent efforts to provide seasonal forecasts of Alexandrium bloom magnitude, and near-real time hindcasts and forecasts of use to resource managers.
