description: We suggest a new approach to the detection of gravitational waves using observations of a group of millisecond pulsars. In contrast to the usual method, based on increasing the accuracy of the arrival times of pulses by excluding possible distorting factors, our method supposes that the additive phase noise that is inevitably present even in the most accurate observational data has various spectral components, which have characteristic amplitudes and begin to appear on different time scales. We use the "Caterpillar" (Singular Spectral Analysis, SSA) method to decompose the signal into its components. Our initial data are the residuals of the pulse arrival times for six millisecond pulsars. We constructed the angular correlation function for components of the decomposition of a given number, whose theoretical form for the case of an isotropic and homogeneous gravitational-wave background is known. The individual decomposition components show a statistically significant agreement with the theoretical expectations (correlation coefficient $ρ=0.92\pm 0.10$).

description: How does European integration affect the welfare state? This paper argues that European integration has non-complementary consequences for the political economy of welfare spending: European economic integration increases popular demand for social spending, whereas European political integration decreases the supply of social spending. Thus, the conflicting implications of European integration essentially break the link between social policy preferences and social policy. Using statistical models that deal with the multilevel structure of the theoretical argument, we find a positive relationship between economic integration and support for social policy. In the second part of the empirical analysis, dynamic model specifications at the country level show that higher levels of political integration are associated with lower levels of social spending. Furthermore, we provide evidence that social policy responsiveness declines as political integration increases.

description: We show that inclusive single-spin asymmetries (SSAs) with transversely polarized protons or electrons at a future electron ion collider (EIC) are sensitive to new physics contributions to electroweak dipole operators of electrons and quarks. We use the Standard Model Effective Field Theory (SMEFT) to parameterize possible heavy new physics contributions to these couplings. We show that new physics scales at or beyond the TeV-scale can be probed assuming realistic EIC run parameters, and that the transverse spin asymmetries are sensitive to different combinations of the dipole couplings than other measurements such as anomalous magnetic or electric dipole moments. We also study the physics potential of SSAs at a possible future upgrade of the EIC to collide muons and protons. Measurements at such an upgrade could probe the same SMEFT parameters that explain the current anomaly in the muon anomalous magnetic moment, and could also improve current bounds on the muon electric dipole moment.

description: We consider a theoretical model for the chiral smectic A twisted ribbons observed in assemblies of fd viruses condensed by depletion forces. The depletion interaction is modeled by an edge energy assumed to be proportional to the depletant polymer in solution. Our model is based on the Helfrich energy for surface bending and the de Gennes model of chiral smectic A liquid crystals with twist penetration at the edge. We consider two variants of this model, one with the conventional Helfrich Gaussian curvature term, and a second with saddle-splay energy. A mean field analysis of both models yields a first-order phase transition between ribbons and semi-infinite flat membranes as the edge energy is varied. The phase transition line and tilt angle profile are found to be nearly identical for the two models; the pitch of the ribbon, however, does show some differences. Our model yields good qualitative agreement with experimental observations if the sign of the Gaussian curvature or saddle-splay modulus is chosen to favor negative Gaussian curvature.

description: Rod-shaped particles embedded in certain matrices have been reported to exhibit an increase in their center of mass diffusivity upon increasing the matrix density. This increase has been considered to be caused by a kinetic constraint in analogy with tube models. We investigate a mobile rod-like particle in a sea of immobile point obstacles using a kinetic Monte Carlo scheme equipped with a Markovian process, that generates gas-like collision statistics, so that such kinetic constraints do essentially not exist. Even in such a system, provided the particle's aspect ratio exceeds a threshold value of about 24, the unusual increase in the rod diffusivity emerges. This result implies that the kinetic constraint is not a necessary condition for the increase in the diffusivity.

description: Shallow lake ecosystems are widely impaired by eutrophication. Lake restoration projects frequently fail or are only partially successful, reflecting that environmental managers face difficult challenges in addressing this complex problem. Key uncertainties relate to selecting appropriate methods and predicting the resulting response trajectory, that is, “what should be done, how much improvement should be expected, and how long will it take?” This review critically evaluates approaches applied to address eutrophication in shallow lakes. A set of shallow lake restoration case studies from across the globe, involving moderate to high effort monitoring, was evaluated to determine common features and to identify advantages/disadvantages and drivers of successful restoration projects. Approaches are broadly grouped into four categories: 1) external nutrient load reductions, 2) internal nutrient load reductions, 3) biomanipulation, and 4) hydrological manipulations. Case studies highlight that external load reduction is an essential component of successful restoration, although supplementary measures can support restoration goals. To inform planning and help set realistic expectations, the following key challenges to the restoration of shallow lakes were identified: 1) insufficient reductions in external nutrient loads, 2) biogeochemical lags, 3) resistance of a stable, algal-dominated state due to hysteresis in the turbidity–nutrient load relationship, 4) delayed macrophyte reestablishment, 5) climate change, 6) need for lake-specific approaches, and 7) social and political shortcomings. Managing these challenges is crucial to the success of shallow lake restoration projects.

description: Parametric polymorphism is widely present in modern programming languages, but only some of them support type parameters of variable arity. In this work we give a classification of polymorphism and make a review of how existing languages deal with variably-sized type parameters. We then suggest a syntax extension for Kotlin, that is implemented in a compiler prototype. We also give our evaluation of the new approach based on the testing results.

description: We present measurements of $ab$-plane resistivity $ρ_{ab}(T)$ and superfluid density [$\propto λ^{-2}$, $λ$ = magnetic penetration depth] in $La_{2-x}Sr_{x}CuO_{4}$ films. As Sr concentration $x$ exceeds about 0.22, the superconducting transition sharpens dramatically, becoming as narrow as 200 mK near the super-to-normal metal quantum critical point. At the same time, $ρ_{ab}(T)$, $λ^{-2}(T)$, and transition temperature $T_c$ decrease, and upward curvature develops in $λ^{-2}(T)$. Given the sharp transitions, we interpret these results in the context of a homogeneous d-wave superconducting state, with elastic scattering that is enhanced relative to underdoped LSCO due to weaker electron correlations. This interpretation conflicts with the viewpoint that the overdoped state is inhomogeneous due to phase separation into superconducting and normal metal regions.

Decay spectroscopy of europium-160
Creators: name: Yates, Daniel
Publisher: name: University of British Columbia
Year: 2019

description: Nuclei far from the traditional proton and neutron shell closures with “magic numbers” often deviate from spherical shapes and are deformed. The excited- state structure of these nuclei is built on the interplay of collective motions with single-particle degrees of freedom. Neutron-rich europium (Z = 63) nuclei around N = 104 are located midshell in both proton and neutron number. These nuclei exist in a region of large deformation, and the excited- state structure of these nuclei has not been studied in-depth yet. β-decay data was taken for a number of neutron-rich europium isotopes, including ¹⁶⁰Eu, at TRIUMF-ISAC using the GRIFFIN spectrometer. For this thesis, a comprehensive β-decay study was carried out on ¹⁶⁰Eu and the daughter ¹⁶⁰Gd. 10 new excited states and 41 new transitions have been identified in the excited-state level scheme of ¹⁶⁰Gd, and for the first time, a thorough analysis on the β-decay of ¹⁶⁰Eu was completed.
title: DEPRECATED: An Analysis of the Genetic Algorithm and Abstract Search Space Visualisation
Creators: name: HARRIS, RICHARD ALAN
Publisher: name: University of Plymouth
Year: 1996

description: The Genetic Algorithm (Holland, 1975) is a powerful search technique based upon the principles of Darwinian evolution. In its simplest form the GA consists of three main operators - crossover, mutation and selection. The principal theoretical treatment of the Genetic Algorithm (GA) is provided by the Schema Theorem and building block hypothesis (Holland, 1975). The building block hypothesis describes the GA search process as the combination, sampling and recombination of fragments of solutions known as building blocks. The crossover operator is responsible for the combination of building blocks, whilst the selection operator allocates increasing numbers of samples to good building blocks. Thus the GA constructs the optimal (or near-optimal) solution from those fragments of solutions which are, in some sense, optimal. The first part of this thesis documents the development of a technique for the isolation of building blocks from the populations of the GA. This technique is shown to extract exactly those building blocks of interest - those which are sampled most regularly by the GA. These building blocks are used to empirically investigate the validity of the building block hypothesis. It is shown that good building blocks do not combine to form significantly better solution fragments than those resulting from the addition of randomly generated building blocks to good building blocks. This results casts some doubt onto the value of the building block hypothesis as an account of the GA search process (at least for the functions used during these experiments). The second part of this thesis describes an alternative account of the action of crossover. This account is an approximation of the geometric effect of crossover upon the population of samples maintained by the GA. It is shown that, for a simple function, this description of the crossover operator is sufficiently accurate to warrant further investigation. A pair of performance models for the GA upon this function are derived and shown to be accurate for a wide range of crossover schemes. Finally, the GA search process is described in terms of this account of the crossover operator and parallels are drawn with the search process of the simulated annealing algorithm (Kirkpatrick et al, 1983). The third and final part of this thesis describes a technique for the visualisation of high dimensional surfaces, such as are defined by functions of many parameters. This technique is compared to the statistical technique of projection pursuit regression (Friedman & Tukey, 1974) and is shown to compare favourably both in terms of computational expense and quantitative accuracy upon a wide range of test functions. A fundamental flaw of this technique is that it may produce poor visualisations when applied to functions with a small high frequency (or order) components.

description: How do policies change? The article argues that dominant public policy theories overemphasize the stage of adoption of new policies and disregard the discrepancies that often take place between formal and substantive change. But can we really speak of change if formal changes do not trigger change in actors’ behaviour? And how can policy-makers achieve substantive change? Building on the comparative political economy literature, the article conceptualizes policy change as the interaction between rule-makers and rule-takers. It is argued that (i) rule-makers can use policy design strategically to minimize reliance on non-compliant rule-takers and (ii) the scope for rule-makers to side-line non-compliant rule-takers is greater if non-compliant behaviour produces negative policy feedback. Systematic process analysis of reform of German higher education over two decades lends support to the proposed approach.

description: We have analyzed the atomic rearrangements underlying self-diffusion in amorphous Si during annealing using tight-binding molecular dynamics simulations. Two types of amorphous samples with different structural features were used to analyze the influence of coordination defects. We have identified several types of atomic rearrangement mechanisms, and we have obtained an effective migration energy of around 1 eV. We found similar migration energies for both types of samples, but higher diffusivities in the one with a higher initial percentage of coordination defects.

description: We classify the dissipative topological insulators (TIs) with edge dark states (EDS) by using the 38-fold way of non-Hermitian systems in this paper. The dissipative dynamics of these quadratic open fermionic systems is captured by a non-Hermitian single-particle matrix which contains both the internal dynamics and the dissipation, refereed to as damping matrix $X$. And the dark states in these systems are the eigenmodes of $X$ which the eigenvalues' imaginary part vanishes. However, there is a constraint on $X$, namely that the modes in which the eigenvalues' imaginary parts are positive are forbidden. In other words, the imaginary line-gap of $X$ is ill-defined, so the topological band theory classifying the dark states can not be applied to $X$. To reveal the topological protection of EDS, we propose the double damping matrix $\tilde{X} = \text{diag}\left( X, X^* \right)$, where the imaginary line-gap is well defined. Thus, the 38-fold way can be applied to $\tilde{X}$, and the topological protection of the EDS is uncovered. Different from previous studies of EDS in purely dissipative dynamics, the EDS in the dissipative TIs are robust against the inclusion of Hamiltonians. Furthermore, the topological classification of $\tilde{X}$ not only reflects the topological protection of EDS in dissipative TIs but also provides a paradigm to predict the appearance of EDS in other open free fermionic systems.

description: We present the gravitational wave signatures for a suite of axisymmetric core collapse supernova models with progenitors masses between 12 and 25 solar masses. These models are distinguished by the fact they explode and contain essential physics (in particular, multi-frequency neutrino transport and general relativity) needed for a more realistic description. Thus, we are able to compute complete waveforms (i.e., through explosion) based on non-parameterized, first-principles models. This is essential if the waveform amplitudes and time scales are to be computed more precisely. Fourier decomposition shows that the gravitational wave signals we predict should be observable by AdvLIGO across the range of progenitors considered here. The fundamental limitation of these models is in their imposition of axisymmetry. Further progress will require counterpart three-dimensional models.

description: EU agencies are increasingly subject to a flurry of stakeholder bodies. Despite their prevalence, and the considerable variation in structures formally professed to serve the same purpose, we know little about the actor preferences driving the set-up of such structures or the potential implications of specific institutional design choices. We systematically map structural variations across EU agencies and analyse to what extent the establishment and the design of stakeholder bodies is principal-imposed or agency-initiated. Do stakeholder structures enhance political control serving to broadly legitimise agencies, or to the contrary, do they reflect preferences of the bureaucratic actors they are meant to control, and with what implications? We find that, for the most part, weak principal control and steering leaves it to the agencies themselves to design stakeholder bodies as they see fit. This has the potential to introduce unsanctioned biases in favour of specific groups, potentially depleting rather than bolstering legitimacy. A major implication of EU agencies’ stakeholder engagement is that the agency model is currently in flux, moving away from the classic insulated agency towards greater politicization in regulatory policy.

Determination of the top-quark mass from top-quark pair events with the matrix element method at next-to-leading order: Potential and prospects

description: In 2004 the matrix element method was used in a pioneering work by the Tevatron experiment D0 to determine the top-quark mass from a handful of events. Since then the method has been matured into a powerful analysis tool. While the first applications were restricted to leading-order accuracy, in the meantime also the extension to next-to-leading order (NLO) accuracy has been studied. In this article we explore the potential of the matrix element method at NLO to determine the top-quark mass using events with pair-produced top quarks. We simulate a toy experiment by generating unweighted events with a fixed input mass and apply the matrix element method to construct an estimator for the top-quark mass. Two different setups are investigated: unweighted events obtained from the fixed-order cross section at NLO accuracy as well as events obtained using POWHEG matched to a parton shower. The latter lead to a more realistic simulation and allow to study the impact of higher-order corrections as well as the robustness of the approach. We find that the matrix element method in NLO accuracy leads to a significant reduction of the theoretical uncertainties compared to leading order. In view of the high luminosity phase of the LHC, this observation is especially relevant in analyses which are no longer dominated by statistical uncertainties.

Quark-lepton Yukawa ratios and nucleon decay in SU(5) GUTs with type-III seesaw

description: We consider an extension of the Georgi-Glashow SU(5) GUT model by a 45-dimensional scalar and a 24-dimensional fermionic representation, where the latter leads to the generation of the observed light neutrino masses via a combination of a type I and a type III seesaw mechanism. Within this scenario, we investigate the viability of predictions for the ratios between the charged lepton and down-type quark Yukawa couplings, focusing on the second and third family. Such predictions can emerge when the relevant entries of the Yukawa matrices are generated from single joint GUT operators (i.e. under the condition of single operator dominance). We show that three combinations are viable, (i) $y_τ/y_b=3/2$, $y_μ/y_s=9/2$, (ii) $y_τ/y_b=2$, $y_μ/y_s=9/2$, and (iii) $y_τ/y_b=2$, $y_μ/y_s=6$. We extend these possibilities to three toy models, accounting also for the first family masses, and calculate their predictions for various nucleon decay rates. We also analyse how the requirement of gauge coupling unification constrains the masses of potentially light relic states testable at colliders.

description: In this paper, we study the production of spin-one color-octet resonances (colorons) at hadron colliders in a model independent way. We use dijets data measured by CDF (at \sqrt{s}=1.96 TeV and L=1.13$ 1/pb) and ATLAS (at \sqrt{s}=7$ TeV and L=315 1/nb) collaborations at the Tevatron and the LHC respetively to impose limits on the coupling of colorons to fermions. We show that CDF data still produce the more stringent limits on the coloron coupling constant.

Multivariate supOU processes

Subjects: subject: Probability (math.PR)

description: Univariate superpositions of Ornstein--Uhlenbeck-type processes (OU), called supOU processes, provide a class of continuous time processes capable of exhibiting long memory behavior. This paper introduces multivariate supOU processes and gives conditions for their existence and finiteness of moments. Moreover, the second-order moment structure is explicitly calculated, and examples exhibit the possibility of long-range dependence. Our supOU processes are defined via homogeneous and factorizable Lévy bases. We show that the behavior of supOU processes is particularly nice when the mean reversion parameter is restricted to normal matrices and especially to strictly negative definite ones. For finite variation Lévy bases we are able to give conditions for supOU processes to have locally bounded càdlàg paths of finite variation and to show an analogue of the stochastic differential equation of OU-type processes, which has been suggested in \cite barndorffnielsen01 in the univariate case. Finally, as an important special case, we introduce positive semi-definite supOU processes, and we discuss the relevance of multivariate supOU processes in applications.

Motor models in action prediction : a test of practice experience generalization when throwing darts with a weight
Creators: name: Chan, Brennan
Publisher: name: University of British Columbia
Year: 2019

description: Previous studies have provided evidence consistent with the proposal that people “simulate” observed actions, based on their own motor experiences, to help predict the outcome of others’ actions. This simulation is believed to be based on low-level activation of the observer’s motor system at the time of the decision. In this experiment, we tested how closely people’s motor experiences influence their ability to predict action outcomes and whether these experiences generalize to predicting outcomes of novel stimuli. To do this, we manipulated the experiences (and therefore, the type of internal model formed during physical practice), by asking people to practice throwing darts with or without a wrist weight. Participants were asked to predict outcomes of people throwing under opposite or the same conditions as those experienced during practice. Although we showed evidence that prediction ability is specific to one’s practice experience, this was only seen in people who physically practiced without a weight and not for people who physically practiced with a wrist weight. The contribution of the motor system to these predictive decisions was also assessed by secondary-motor tasks designed to probe motor system involvement during prediction. Although we showed that predicting dart outcomes while wearing a wrist weight aided prediction accuracy, this was only observed in people who physically practiced without a weight. Contrary to previous studies, we were unable to show interference from a secondary, incongruent movement task (light press on a force gauge) after physical practice. Both physical and perceptual practice resulted in improvement in prediction accuracy post-practice, although this was strongest for the no-weight physical practice group. Overall, these data provide evidence that physical practice transfers to improvement in perceptually-driven predictive decisions. However, although the secondary tasks gave some evidence that prediction was dependent on the motor system (when holding a weight), and that the type of motor experience (weight or no-weight) impacts predictive decisions, evidence for motor simulation was not shown. Limits of the current methods are discussed.

description: Although many studies compare national integration policies, analyses connecting these policies to integration outcomes are rare. This study combines longitudinal analysis of employment outcomes for Scandinavian refugees, with analyses of integration measures and policies to explain these differences. Can different usages of integration measures explain cross-national differences in employment outcomes between genders and with increased residence time? Moreover, can the countries’ integration policies explain such differences? Our analyses show substantial cross-national differences. Danish male refugees are employed faster; however, Sweden catches up, and Norway surpasses Danish employment levels with increased residence time. Additionally, Norway has a substantially smaller gender gap in employment than Sweden and particularly Denmark. We demonstrate that different usages of integration measures may explain differences in outcomes. We conjecture that different policies regulating (1) financial benefits and (2) employment and self-sufficiency requirements for obtaining a secure legal status may reinforce differences in programme participation and employment patterns.

description: We present the splashback radius measurements around the SRG/eROSITA eFEDS X-ray selected galaxy clusters by cross-correlating them with HSC S19A photometric galaxies. The X-ray selection is expected to be less affected by systematics related to projection that affects optical cluster finder algorithms. We use a nearly volume-limited sample of 109 galaxy clusters selected in 0.5-2.0 keV band having luminosity $L_X > 10^{43.5}\,{\rm erg s^{-1} h^{-2}}$ within the redshift $z<0.75$ and obtain measurements of the projected cross-correlation with a signal-to-noise of $17.43$. We model our measurements to infer a three-dimensional profile and find that the steepest slope is sharper than $-3$ and associate the location with the splashback radius. We infer the value of the 3D splashback radius $r_{\rm sp} = 1.45^{+0.30}_{-0.26}\,{\rm h^{-1} Mpc}$. We also measure the weak lensing signal of the galaxy clusters and obtain halo mass $\log[M_{\rm 200m}/{\rm h^{-1}M_\odot}] = 14.52 \pm 0.06$ using the HSC-S16A shape catalogue data at the median redshift $z=0.46$ of our cluster sample. We compare our $r_{\rm sp}$ values with the spherical overdensity boundary $r_{\rm 200m} = 1.75 \pm 0.08\,{\rm h^{-1} Mpc}$ based on the halo mass which is consistent within $1.2σ$ with the $Λ$CDM predictions. Our constraints on the splashback radius, although broad, are the best measurements thus far obtained for an X-ray selected galaxy cluster sample.

description: A new technique for manipulation and control of gradient-driven instabilities through nonlinear interaction with Alfvén waves in a laboratory plasma is presented. A narrow field-aligned density depletion is created in the Large Plasma Device (LAPD), resulting in coherent unstable fluctuations on the periphery of the depletion. Two independent kinetic Alfvén waves are launched along the depletion at separate frequencies, creating a nonlinear beat-wave response at or near the frequency of the original instability. When the beat-wave has sufficient amplitude, the original unstable mode is suppressed, leaving only the beat-wave response at a different frequency, generally at lower amplitude.

description: Planar tunneling spectroscopy of the Kondo insulator SmB$_6$ suggests that an interaction between the surface Dirac fermions and the bulk spin excitons results in incompletely protected topological surface states. To gain further insight into their true nature, it is necessary to study other topological Kondo insulator candidates. Calculations of electronic energy bands predict that the Kondo insulator YbB$_{12}$ hosts topological surface states protected by crystalline mirror symmetry. In this study, we present tunneling conductance spectra obtained from the (001) surface of YbB$_{12}$ single crystals and discuss them in comparison to SmB$_6$. The linear conductance at low bias provides strong evidence for the existence of surface Dirac fermions. The double-hump structure in the negative bias region is associated with hybridized band edges, in agreement with a calculated band structure. While these similarities with SmB6 are suggestive of the existence of topological surface states in YbB$_{12}$, in agreement with other experiments, some discrepancies are also observed, which we attribute to a difference in their exact nature from those in SmB$_6$.

description: In recent years, Fractal Inspired Models of quark and gluon densities at small x have been proposed. In this paper, we investigate longitudinal structure function F-L (x, Q2) within this approach. We make predictions using the QCD based approximate relation between the longitudinal structure function and the gluon density. As the Altarelli-Martinelli equation for the longitudinal structure function cannot be applied to Model I due to the presence of a singularity in the Bjorken x-space we consider Model II only. The qualitative feature of the prediction of Model II is found to be compatible with the QCD expectation.

description: The timescales on which galaxies move out of the blue cloud to the red sequence ($τ^{}_\mathrm{Q}$) provide insight into the mechanisms driving quenching. Here, we build upon previous work, where we showcased a method to reconstruct the colour evolution of observed low-redshift galaxies from the Galaxy And Mass Assembly (GAMA) survey based on spectral energy distribution (SED) fitting with ProSpect, together with a statistically-driven definition for the blue and red populations. We also use the predicted colour evolution from the SHARK semi-analytic model, combined with SED fits of our simulated galaxy sample, to study the accuracy of the measured $τ^{}_\mathrm{Q}$ and gain physical insight into the colour evolution of galaxies. In this work, we measure $τ^{}_\mathrm{Q}$ in a consistent approach for both observations and simulations. After accounting for selection bias, we find evidence for an increase in $τ^{}_\mathrm{Q}$ in GAMA as a function of cosmic time (from $τ^{}_\mathrm{Q}\sim1$ Gyr to $τ^{}_\mathrm{Q}\sim2$ Gyr in the lapse of $\sim4$ Gyr), but not in SHARK ($τ^{}_\mathrm{Q}\lesssim1$ Gyr). Our observations and simulations disagree on the effect of stellar mass, with GAMA showing massive galaxies transitioning faster, but is the opposite in SHARK. We find that environment only impacts galaxies below $\sim10^{10}$ M$_\odot$ in GAMA, with satellites having shorter $τ^{}_\mathrm{Q}$ than centrals by $\sim0.4$ Gyr, with SHARK only in qualitative agreement. Finally, we compare to previous literature, finding consistency with timescales in the order of couple Gyr, but with several differences that we discuss.
