description: We present the analytical calculation of the four-loop quark mass anomalous dimension in Quantum Chromodynamics within the minimal subtraction scheme. On the basis of this result we find that the so-called invariant quark mass is a very good reference mass for the accurate evolution of the running MS-bar quark mass in phenomenological applications. We also obtain for the first time a complete 4-th order perturbative QCD expression for a physical quantity, the total Higgs boson decay rate into hadrons, and analyze the infrared fixed point for this case.

description: We investigate the formation of a two-dimensional quasicrystal in a monodisperse system, using molecular dynamics simulations of hard sphere particles interacting via a two-dimensional square-well potential. We find that more than one stable crystalline phase can form for certain values of the square-well parameters. Quenching the liquid phase at a very low temperature, we obtain an amorphous phase. By heating this amorphous phase, we obtain a quasicrystalline structure with five-fold symmetry. From estimations of the Helmholtz potentials of the stable crystalline phases and of the quasicrystal, we conclude that the observed quasicrystal phase can be the stable phase in a specific range of temperatures.

description: We introduce and explore a natural rank for totally disconnected locally compact groups called the bounded conjugacy rank. This rank is shown to be a lattice invariant for lattices in sigma compact totally disconnected locally compact groups; that is to say, for a given sigma compact totally disconnected locally compact group, some lattice has bounded conjugacy rank n if and only if every lattice has bounded conjugacy rank n. Several examples are then presented.

description: We investigate the discovery potential for first generation leptoquarks at the LEP200 $e^+e^-$ collider. We consider direct leptoquark searches using single leptoquark production via resolved photon contributions which offers a much higher kinematic limit than the more commonly considered leptoquark pair production process. Depending on the coupling strength of the leptoquark, search limits can be obtained to within a few GeV of $\sqrt{s}$. We also consider LQ limits that can be obtained from t-channel interferences effects in $e^+e^- \to hadrons$.

description: The action for a relativistic free particle of mass $m$ receives a contribution $-mds$ from a path segment of infinitesimal length $ds$. Using this action in a path integral, one can obtain the Feynman propagator for a spinless particle of mass $m$. If one of the effects of quantizing gravity is to introduce a minimum length scale $L_P$ in the spacetime, then one would expect the segments of paths with lengths less than $L_P$ to be suppressed in the path integral. Assuming that the path integral amplitude is invariant under the `duality' transformation $ds\to L_P^2/ds$, one can calculate the modified Feynman propagator. I show that this propagator is the same as the one obtained by assuming that: quantum effects of gravity leads to modification of the spacetime interval $(x-y)^2$ to $(x-y)^2+L_P^2$. This equivalence suggests a deep relationship between introducing a `zero-point-length' to the spacetime and postulating invariance of path integral amplitudes under duality transformations.

description: Traditional cosmological hydrodynamics simulations fail to spatially resolve the circumgalatic medium (CGM), the reservoir of tenuous gas surrounding a galaxy and extending to its virial radius. We introduce the technique of Enhanced Halo Resolution (EHR), enabling more realistic physical modeling of the simulated CGM by consistently forcing gas refinement to smaller scales throughout the virial halo of a simulated galaxy. We investigate the effects of EHR in the Tempest simulations, a suite of Enzo-based cosmological zoom simulations following the evolution of an L* galaxy, resolving spatial scales of 500 comoving pc out to 100 comoving kpc in galactocentric radius. Among its many effects, EHR (1) changes the thermal balance of the CGM, increasing its cool gas content and decreasing its warm/hot gas content; (2) preserves cool gas structures for longer periods; and (3) enables these cool clouds to exist at progressively smaller size scales. Observationally, this results in a boost in "low ions" like H I and a drop in "high ions" like O VI throughout the CGM. These effects of EHR do not converge in the Tempest simulations, but extrapolating these trends suggests that the CGM in reality is a mist consisting of ubiquitous, small, long-lived, cool clouds suspended in a hot medium at the virial temperature of the halo. Additionally, we explore the physical mechanisms to explain why EHR produces the above effects, proposing that it works both by (1) better sampling the distribution of CGM phases enabling runaway cooling in the denser, cooler tail of the phase distribution; and (2) preventing cool gas clouds from artificially mixing with the ambient hot halo and evaporating. Evidence is found for both EHR mechanisms occurring in the Tempest simulations.

description: Crowd counting, i.e., estimation number of the pedestrian in crowd images, is emerging as an important research problem with the public security applications. A key component for the crowd counting systems is the construction of counting models which are robust to various scenarios under facts such as camera perspective and physical barriers. In this paper, we present an adaptive scenario discovery framework for crowd counting. The system is structured with two parallel pathways that are trained with different sizes of the receptive field to represent different scales and crowd densities. After ensuring that these components are present in the proper geometric configuration, a third branch is designed to adaptively recalibrate the pathway-wise responses by discovering and modeling the dynamic scenarios implicitly. Our system is able to represent highly variable crowd images and achieves state-of-the-art results in two challenging benchmarks.

Pressures, impacts, conservation, and management

description: No abstracts are to be cited without prior reference to the author.Interspecific hybridization is common in many fish, including redfish of the genus Sebastes. Studies of this phenomenon are interesting in terms of evolutionary genetics as well as conservation genetics. Specimens that were morphologically intermediate between S. mentella and S. marinus were found as early as the 1960s, when investigations of S. mentella were initiated in the Irminger Sea. A large number of these hybrids (13.3%) in that area was revealed later by genetic analysis. We searched for S. mentella hybridized with S. fasciatus and S. viviparus in samples of redfish with external traits typical of S. mentella. The samples were collected in the Irminger Sea in 2007 (n = 131) and 2010 (n = 72). Hybrids were identified using MDH‐2* locus coding malate dehydrogenase. The samples contained hybrids with 0.0152 and 0.0138 frequency, respectively. It should be mentioned that the allele typical of S. viviparus and S. fasciatus had been observed already in samples of beaked redfish collected in different years and at different depths of the Irminger Sea. In 2000, its average frequency was 0.05 in samples taken at more than 500 m depth. The results from our investigations reveal that interspecific hybridization may have a strong impact on the genetic structure of S. mentella in the Irminger Sea, presumably being one of the main reasons why allele frequencies of a number of genes is different between samples collected at different depths. This should be taken into consideration in population structure studies.

description: A detailed investigation by one-step photoemission calculations of the GaN(0001)-(1x1) surface in comparison with recent experiments is presented in order to clarify its structural properties and electronic structure. The discussion of normal and off-normal spectra reveals through the identified surface states clear fingerprints for the applicability of a surface model proposed by Smith et al. Especially the predicted metallic bonds are confirmed. In the context of direct transitions the calculated spectra allow to determine the valence band width and to argue in favor of one of two theoretical bulk band structures. Furthermore a commonly used experimental method to fix the valence band maximum is critically tested.

description: A novel approach was employed to load α-Fe2O3 and α-FeOOH onto sewage sludge biochar (SBC) with the purpose of efficient nickel (Ni) removal. A high Ni(II) adsorption capacity of 35.50 mg·g-1 in 100 ppm Ni(II) solution with 10 mg modified sewage sludge biochar (MSBC) was achieved. The adsorption kinetic and isotherm were fitted well by the pseudo-second-order model and the Langmuir model, respectively. The optimal pH was found around a neutral pH of 7. The adsorption mechanisms of Ni(II) onto MSBC were described as the synergistic effects of electrostatic attraction, ion exchange, inner-sphere complexation and co-precipitation. The initial rapid adsorption phenomenon could be attributed to electrostatic attraction and ion exchange, and then inner-sphere complexation and co-precipitation acted as a crucial role in the following step. The remarkable performance of MSBC provides an effective waste utilization approach to simultaneous sewage sludge recycle and Ni removal from aqueous solution.
title: Culture and strategy in the North American middle powers during the neoliberal era. The politics of strategic policy in Mexico and Canada, 1988-2015
Creators: name: Barrera Franco, Carlos Alberto
Publisher: name: Unversity of Glasgow

description: This is a study of the evolution of the strategic policy of Mexico and Canada during the advent and consolidation of neoliberalism in North America. The thesis examines the interaction between the various strategic approaches rooted in policy elites in the late twentieth and early twenty-first centuries. In the case of Mexico, the struggle between the historical nationalist doctrine and emerging continentalist practices is analysed. In the case of Canada, tensions between the liberal internationalist tradition, the Atlanticist strategic approach, and the renewed continentalist notion are evaluated. This dissertation pays special attention to the socio-political context in which foreign, trade, and security policies were formulated; as well as the cultural dynamics of the strategic decision-making process. The study reconsiders the responses of Mexican and Canadian policy elites to domestic and external pressures that occurred from 1988 to 2015. Based on a structuralist-constructivist approach focused on practice, this work provides a new interpretation of continuity and change in strategic policy before and after the political transitions of Mexico and Canada in 2000 and 2006, respectively. This thesis shows why and how the major strategic traditions of Canada and Mexico were gradually replaced by continentalist ideas, which were much more influential throughout this period than is commonly recognised. The result is a comprehensive reassessment of the foreign policy and security strategies of the middle powers of North America from an emerging perspective in the discipline of international history and international relations during a pivotal period in contemporary history: the neoliberal era.

description: We discuss models where N=1 global supersymmetry is spontaneously broken, at the classical level, in the presence of non-anomalous gauge interactions. We take such models as effective theories, valid up to some suitable scale and arising from supergravity models with a light gravitino, and therefore we allow them to contain non-renormalizable interactions. First, we examine the case where the goldstino is a gauge singlet. We elucidate the model-independent relations between supersymmetry-breaking masses and some associated interactions, with special attention to the behaviour of some four-particle scattering amplitudes in the high- and low-energy limits. The former gives constraints from tree-level unitarity, the latter affects the phenomenological lower bounds on the gravitino mass. In particular, we give new results for the annihilation of photons into gravitinos, and discuss their implications. We then examine the case with no neutral chiral superfields, so that the goldstino is charged, and the gauge symmetry is also broken. In this context, we discuss the singularity structure and the associated unitarity constraints, relating the scales of supersymmetry and gauge symmetry breaking. We conclude by commenting on possible realistic examples, where the broken gauge symmetry is associated with grand or electroweak unification.

description: We analyze nonperturbatively the behavior of a Josephson junction in which two BCS superconductors are coupled through an Anderson impurity. We recover earlier perturbative results which found that a $δ=π$ phase difference is preferred when the impurity is singly occupied and the on-site Coulomb interaction is large. We find a novel intermediate phase in which one of $δ=0$ and $δ=π$ is stable while the other is metastable, with the energy $E(δ)$ having a kink somewhere in between. As a consequence of the kink, the $I-V$ characteristics of the junction are modified at low voltages.

description: We consider the Quantum Null Energy Condition (QNEC) for holographic conformal field theories in two spacetime dimensions (CFT$_2$). We show that QNEC saturates for all states dual to vacuum solutions of AdS$_3$ Einstein gravity, including systems that are far from thermal equilibrium. If the Ryu-Takayanagi surface encounters bulk matter QNEC does not need to be saturated, whereby we give both analytical and numerical examples. In particular, for CFT$_2$ with a global quench dual to AdS$_3$-Vaidya geometries we find a curious half-saturation of QNEC for large entangling regions. We also address order one corrections from quantum backreactions of a scalar field in AdS$_3$ dual to a primary operator of dimension $h$ in a large central charge expansion and explicitly compute both, the backreacted Ryu--Takayanagi surface part and the bulk entanglement contribution to EE and QNEC. At leading order for small entangling regions the contribution from bulk EE exactly cancels the contribution from the back-reacted Ryu-Takayanagi surface, but at higher orders in the size of the region the contributions are almost equal while QNEC is not saturated. For a half-space entangling region we find that QNEC is gapped by $h/4$ in the large $h$ expansion.

A comment on the article
Creators: name: Kitis, Eliza

Year: 1987

description: In an attempt to give a solution to the problem of definite descriptions, Grice treats them as a special subclass of referential expressions whose existential presuppositions can be "explained away" in terms of general­ized conversational implicatures. To this end he employs the Russellian tripartite definition of definite descriptions, claiming that the first two clauses of it are regarded by the speaker as common ground, and there­fore as not challengable. He concludes that every use of the definite ar­ticle implicates that the reference is to be taken "on trust" (my empha­sis). It is here argued that this is a reductionistic approach to the description of the use of the article because it does not address the problem in its right form as the parameters pertaining to the use of the article are, and should be, isolatable from speakers and their erratic or idiosyncratic im­plicatures and are rather affected by GENERAL principles governing their use. The main concern of this investigation, however, is to emphasize the signi­ficance of stereotypic knowledge we, as speakers and hearers, bring to bear on our use of the definite article. It is concluded that, although treating 'definiteness' within a sound framework, workers on the topic have in a large measure overlooked this point.

description: We present the results of first-principles cluster calculations of the electronic structure of La_2CuO_4. Several clusters containing up to nine copper atoms embedded in a background potential were investigated. Spin-polarized calculations were performed both at the Hartree-Fock level and with density functional methods with generalized gradient corrections to the local density approximation. The distinct results for the electronic structure obtained with these two methods are discussed. The dependence of the electric-field gradients at the Cu and the O sites on the cluster size is studied and the results are compared to experiments. The magnetic hyperfine coupling parameters are carefully examined. Special attention is given to a quantitative determination of on-site and transferred hyperfine fields. We provide a detailed analysis that compares the hyperfine fields obtained for various cluster sizes with results from additional calculations of spin states with different multiplicities. From this we conclude that hyperfine couplings are mainly transferred from nearest neighbor Cu^{2+} ions and that contributions from further distant neighbors are marginal. The mechanisms giving rise to transfer of spin density are worked out. Assuming conventional values for the spin-orbit coupling, the total calculated hyperfine interaction parameters are compared to informations from experiments.

We find that the critical Pd concentration for the emergence of the large-moment antiferromagnetic phase is ~0.6 at.%Pd. At the same Pd content, superconductivity is completely suppressed. The existence of a magnetic quantum critical point in the phase diagram, which coincides with the critical point for superconductivity, provides evidence for ferromagnetic spin-fluctuation mediated odd-parity superconductivity, which competes with antiferromagnetic order.

description: We describe a new algorithm for the numerical simulation of quantum spin and boson systems. The method is based on the Trotter decomposition in imaginary time and a decoupling by auxiliary Ising spins. It can be applied, in principle, to arbitrary (random) spin systems, however in general it suffers from the ``minus-sign problem''. This problem is absent in the case of the Ising model in a transverse field in arbitrary dimensions and geometries. We show test results for the spin--1/2 XY model, the one--dimensional transverse Ising model with disorder, and the phase transition induced by a transverse field in the two-dimensional Ising model.

description: Gauge-Yukawa Unification (GYU) is a renormalization group invariant functional relation among gauge and Yukawa couplings which holds beyond the unification point in Grand Unified Theories (GUTs). We present here various models where GYU is obtained by requiring the principles of finiteness and reduction of couplings. We examine the consequences of these requirements for the low energy parameters, especially for the top quark mass. The predictions are such that they clearly distinguish already GYU from ordinary GUTs. It is expected that it will be possible to discriminate among the various GYUs when more accurate measurements of the top quark mass are available.

description: We present some variations affecting the association measure and thresholding on a technique for learning Selectional Restrictions from on-line corpora. It uses a wide-coverage noun taxonomy and a statistical measure to generalize the appropriate semantic classes. Evaluation measures for the Selectional Restrictions learning task are discussed. Finally, an experimental evaluation of these variations is reported.

description: We study a spin-1/2 Kondo impurity coupled to an unconventional host in which the density of band states vanishes either precisely at (``gapless'' systems) or on some interval around the Fermi level (``gapped''systems). Despite an essentially nonlinear band dispersion, the system is proven to exhibit hidden integrability and is diagonalized exactly by the Bethe ansatz.

description: We present the first high-resolution laboratory spectra of X-ray emission following L-shell charge exchange between nickel ions and neutral H2 and He. We employ the commonly used charge exchange models found in XSPEC and SPEX, ACX and SPEX-CX, to simulate our experimental results. We show that significant differences between data and models exist in both line energies and strengths. In particular, we find that configuration mixing may play an important role in generating lines from core-excited states, and may be improperly treated in models. Our results indicate that if applied to astrophysical data, these models may lead to incorrect assumptions of the physical and chemical parameters of the region of interest.

description: No abstracts are to be cited without prior reference to the author.We examined the feeding habits of pelagic juvenile rockfish (Sebastes spp.) collected off Oregon and Washington during 2000, 2002, and 2006 using a combination of stomach content and stable isotope analyses. Species were identified using genetic techniques and the predominant species collected in all years were darkblotched (S. crameri), canary (S. pinniger), yellowtail (S. flavidus), and widow (S. entomelas) rockfish. Analysis of stomach contents by % number revealed that darkblotched rockfish expressed a high degree of variability of their diets, whereas canary, yellowtail, and widow rockfish had high dietary overlap, attributed to the common utilization of copepods and euphausiids. Less overlap in diets was observed among species when % wet weight was examined. Multivariate analysis of stomach content data (% wet weight) revealed significant differences in diet based on distance from shore where caught, fish size and species. Nitrogen stable isotope analyses revealed all rockfish were feeding at about the same trophic level within each year; however there was a 1.5‰ difference between years. Low (more negative) 13C values of rockfish were indicative of primary production from a more offshore origin, with widow consistently expressing the lowest values between years. Comprehensively, these results advance our understanding of some of the important environmental factors that affect young‐of‐the‐year rockfish during their critical pelagic phase.

description: No abstracts are to be cited without prior reference to the author.The beaked redfish in the Barents Sea is at historical low abundance levels as a result of previous overexploitation and is considered as vulnerable by the Norwegian red list. The management of the population is currently based on survey data that only indicate abundance trends, and no analytical assessment is done. Using a Bayesian modelling framework, we have fitted an agestructured stochastic population model to catch and survey data. The model accounts for observation errors, separates natural mortality from fishing mortality, estimates important population dynamical parameters, and provides age‐specific estimates of abundances for ages 6–18 years between 1992 and 2009. Our results indicate that the population increased from 317 (95% CI 188,523) to 824 (316,1723) million individuals during 1992–1997, and gradually decreased to 227 (109,433) million individuals in 2009. The last strong cohorts were born in the late 1980s and early 1990s and the population have subsequently shifted the age distribution from being dominated by young individuals to being dominated by old individuals. Using estimated parameters, assuming no harvesting, generating recruits from a Ricker stock–recruitment curve, and conditioning on the current estimated age distribution, we constructed a population prediction interval by stochastic simulations of the adult population size 100 years forward in time. The population prediction interval indicates that the adult population is expected to decrease to a minimum of 83 (33,343) million individuals in 2014. If harvest is terminated, subsequent years are predicted to demonstrate an increase in adult abundance because of increased contribution to recruitment from the strong cohorts born in the late 1980s and early 1990s.

description: We combine state-of-the-art large-scale first principles calculations with a low-energy continuum model to describe the nearly flat bands of twisted bilayer graphene at the first magic angle $θ=1.08^\circ$. We show that the energy width of the flat band manifold, as well as the energy gap separating it from the valence and conduction bands, can be obtained only if the out-of-plane relaxations are fully taken into account. The results agree both qualitatively and quantitatively with recent experimental outcomes.

Aspectual oppositions in Greek and in English
Creators: name: Psaltou-Joycey, A.
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 1987

description: This paper is an introductory outline of the formal aspectual oppositions found in Greek and in English. It aims to clarify the distinction between the categories of Aspect and Tense; it also inves­tigates the relations between aspectual form and aspectual meaning. The aspectual forms in both languages are developed separately at first, and, then, problematic areas receive more detailed description.

description: We study the temporal and spatial correlations in a one-dimensional model of a heterogeneous fault zone, in the presence of visco-elastic effects. As a function of dynamical weakening and of dissipation, the system exhibits three different "phases" : one in which there are no time correlations between the events, a second, in which there are ``Omori's law'' type temporal correlations, and a third, runaway phase with quasiperiodic system size events.

description: X-ray absorption spectroscopy is a premier element-specific technique for materials characterization. Specifically, the x-ray absorption near-edge structure (XANES) encodes important information about the local chemical environment of an absorbing atom, including coordination number, symmetry, and oxidation state. Interpreting XANES spectra is a key step towards understanding the structural and electronic properties of materials, and as such, extracting structural and electronic descriptors from XANES spectra is akin to solving a challenging inverse problem. Existing methods rely on empirical fingerprints, which are often qualitative or semiquantitative and not transferable. In this paper, we present a machine learning-based approach, which is capable of classifying the local coordination environments of the absorbing atom from simulated K-edge XANES spectra. The machine learning classifiers can learn important spectral features in a broad energy range without human bias and once trained, can make predictions on the fly. The robustness and fidelity of the machine learning method are demonstrated by an average 86% accuracy across the wide chemical space of oxides in eight 3d transition-metal families. We found that spectral features beyond the preedge region play an important role in the local structure classification problem especially for the late 3d transition-metal elements.
