description: We study the introduction of lexical innovations into a community of language users. Lexical innovations, i.e., new terms added to people's vocabulary, play an important role in the process of language evolution. Nowadays, information is spread through a variety of networks, including, among others, online and offline social networks and the World Wide Web. The entire system, comprising networks of different nature, can be represented as a multi-layer network. In this context, lexical innovations diffusion occurs in a peculiar fashion. In particular, a lexical innovation can undergo three different processes: its original meaning is accepted; its meaning can be changed or misunderstood (e.g., when not properly explained), hence more than one meaning can emerge in the population; lastly, in the case of a loan word, it can be translated into the population language (i.e., defining a new lexical innovation or using a synonym) or into a dialect spoken by part of the population. Therefore, lexical innovations cannot be considered simply as information. We develop a model for analyzing this scenario using a multi-layer network comprising a social network and a media network. The latter represents the set of all information systems of a society, e.g., television, the World Wide Web and radio. Furthermore, we identify temporal directed edges between the nodes of these two networks. In particular, at each time step, nodes of the media network can be connected to randomly chosen nodes of the social network and vice versa. In so doing, information spreads through the whole system and people can share a lexical innovation with their neighbors or, in the event they work as reporters, by using media nodes. Lastly, we use the concept of "linguistic sign" to model lexical innovations, showing its fundamental role in the study of these dynamics. Many numerical simulations have been performed.

We establish certain constants, denoted $γ_{h^{\left( r\right) }}\left( m\right) $, which naturally occur in the Laurent expansion of $ζ_{h^{\left( r\right) }}\left( s\right) $. Moreover, we show that the constants $γ_{h^{\left( r\right) }}\left( m\right) $ and integrals involving generalized exponential integral can be written as a finite combination of some special constants.

description: We present a calculation of the hyperfine splittings in bottomonium using lattice Nonrelativistic QCD. The calculation includes spin-dependent relativistic corrections through O(v^6), radiative corrections to the leading spin-magnetic coupling and, for the first time, non-perturbative 4-quark interactions which enter at alpha_s^2 v^3. We also include the effect of u,d,s and c quark vacuum polarisation. Our result for the 1S hyperfine splitting is M(Upsilon,1S) - M(eta_b,1S)= 60.0(6.4) MeV. We find the ratio of 2S to 1S hyperfine splittings (M(Upsilon,2S) - M(eta_b,2S))/ (M(Upsilon,1S) - M(eta_b,1S)) = 0.445(28).
description: 6 pages, 3 figures. An error was recently found in the coefficients of the 4-quark operators in the lattice NRQCD action that we use here. We have therefore redone this calculation with the corrected coefficients and give the full updated version of the paper here
The relationship between exchange rates and stock prices

Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Financial economics

description: The relationship between exchange rates and stock prices is examined in three independent but inter-connected studies. The original contribution of first study is the finding that interest rates have a significant non-liner explanatory power in the relationship between exchange rates and stock prices. The main contribution of the second study is the finding that there are asymmetric volatility spillover effects between exchange rates and stock prices in both developed and emerging countries, particularly during the financial crisis. The third study makes original contribution to knowledge by finding that there is no major deference between Eurozone and non-Eurozone, and between financial and non-financial firms in terms of exchange rate exposures after controlling for market effects. In study 1, the evidence from the M-TECM tests indicate that there is a uni-directional causality from stock prices to exchange rates in the Eurozone, a unidirectional causality in the opposite direction in Brazil, and a bi-directional causality between the variables in Russia. In study 2, the results of the EGARCH tests indicate that there is a uni-directional volatility spillover effect running from stock prices to exchange rates in developed countries and a volatility spillover in the opposite direction in emerging countries. In study 3, the results of the regression tests show that 18% of Eurozone firms and 16% of non-Eurozone firms, and 20% of financial firms and 16% of non-financial firms have significant exchange rate exposures. However, the exposure increases during the financial crisis. Overall, the thesis finds evidences supportive of long-run equilibrium and short-run causal relationships between exchange rates and stock prices in macro level. In micro level, however, the relationship between exchange rate movements and the market value of firms is relatively weak.

Correlation-based sparse inverse Cholesky factorization for fast Gaussian-process inference

description: Gaussian processes are widely used as priors for unknown functions in statistics and machine learning. To achieve computationally feasible inference for large datasets, a popular approach is the Vecchia approximation, which is an ordered conditional approximation of the data vector that implies a sparse Cholesky factor of the precision matrix. The ordering and sparsity pattern are typically determined based on Euclidean distance of the inputs or locations corresponding to the data points. Here, we propose instead to use a correlation-based distance metric, which implicitly applies the Vecchia approximation in a suitable transformed input space. The correlation-based algorithm can be carried out in quasilinear time in the size of the dataset, and so it can be applied even for iterative inference on unknown parameters in the correlation structure. The correlation-based approach has two advantages for complex settings: It can result in more accurate approximations, and it offers a simple, automatic strategy that can be applied to any covariance, even when Euclidean distance is not applicable. We demonstrate these advantages in several settings, including anisotropic, nonstationary, multivariate, and spatio-temporal processes. We also illustrate our method on multivariate spatio-temporal temperature fields produced by a regional climate model.

The solution is expressed by a series formula where the coefficients are explicitly computed in function of the initial data. We also define an energy expression for the solution that is conserved in time. Then, we establish boundary observability inequalities with explicit constants.

The development of an anthropometric data tool for use in the conceptual design of domestic products
Creators: name: Rogers, Nick
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Industrial and product design

description: To design a product that people can use effectively and safely a designer must understand the physical characteristics of humans. Measures of the characteristics of human physical function are defined by anthropometry. Unfortunately some designers carry misconceptions about anthropometry and are sceptical of the benefits of its application to product design. This is confounded by the lack of data on minority groups such as the elderly who are becoming increasingly influential in determining the functional requirements of products. The anthropometric software systems that are presently available to designers have been ineffective in providing designers with appropriate data in a format they can use. A new methodology is proposed for the presentation and retrieval of anthropometric data for product designers. The methodology uses a novel application of task analysis techniques to establish the anthropometric data that describes the physical demands of users. The methodology defines the interaction between the product and the users in performing a task by breaking it down into its distinct actions. Then the physical demands of an action are defined using generic descriptors. These selections and the users' parameters are used to select the related anthropometric data. The parameters of the environment that interact with the product are then used to express the anthropometric data in terms of the functional limits of the product. This enables the selection of appropriate anthropometric data to describe the physical demands of the users and presents the data in a format that can be effectively applied in the product development process. The methodology was validated using a two stage analysis. In the first stage a sample of designers assessed the qualitative and quantitative performance of the usability of the implementation of the method. In the second stage the effectiveness of the methodology was assessed by performing a comparative analysis with an existing system.
Scaling solution for field-dependent gauge couplings in quantum gravity

description: Quantum gravity can determine the dependence of gauge couplings in a scalar field, which is related to possible fifth forces and time varying fundamental "constants". This prediction is based on the scaling solution of functional flow equations. For momenta below the field-dependent Planck mass the quantum scale invariant standard model emerges as an effective low energy theory. For a small non-zero value of the infrared cutoff scale the time-variation of couplings or apparent violations of the equivalence principle turn out to be negligibly small for the present cosmological epoch, unless some further quantum scale symmetry violation beyond the standard model comes into play. More sizable effects of quantum scale symmetry violation are expected during nucleosynthesis or before. Scaling solutions relate field dependence and dependence on the renormalization scale. We find asymptotically free gauge couplings for the standard model coupled to gravity, while for grand unified models the gauge couplings are asymptotically safe with non-zero values at the ultraviolet fixed point. The scaling solution of asymptotically safe metric quantum gravity yields restrictions for model building, as limiting the number of scalars in grand unified theories.

description: We discuss the large-scale geometry of pure mapping class groups of locally finite, infinite graphs, motivated by recent work of Algom-Kfir--Bestvina and the work of Mann--Rafi on the large-scale geometry of mapping class groups of infinite-type surfaces. Using the framework of Rosendal for coarse geometry of non-locally compact groups, we classify when the pure mapping class group of a locally finite, infinite graph is globally coarsely bounded (an analog of compact) and when it is locally coarsely bounded (an analog of locally compact). Our techniques give lower bounds on the first integral cohomology of the pure mapping class group for some graphs and allow us to compute the asymptotic dimension of all locally coarsely bounded pure mapping class groups of infinite rank graphs. This dimension is always either zero or infinite.

description: We propose a 1+1 dimensional CFT dual structure for quantum gravity and matter on the extended 2+1 dimensional BTZ black hole, realized as a quotient of the Poincare patch of AdS$_3$. The quotient spacetime includes regions beyond the singularity, "whiskers", containing timelike and lightlike closed curves, which at first sight seem unphysical. The spacetime includes the usual AdS-asymptotic boundaries outside the horizons as well as boundary components inside the whiskers. We show that local boundary correlators with some endpoints in the whisker regions: (i) are a protected class of amplitudes, dominated by effective field theory even when the associated Witten diagrams appear to traverse the singularity, (ii) describe well-defined diffeomorphism-invariant quantum gravity amplitudes in BTZ, (iii) sharply probe some of the physics inside the horizon but outside the singularity, and (iv) are equivalent to correlators of specific non-local CFT operators in the standard thermofield entangled state of two CFTs. In this sense, the whisker regions can be considered as purely auxiliary spacetimes in which these useful non-local CFT correlators can be rendered as local boundary correlators, and their diagnostic value more readily understood. Our results follow by first performing a novel reanalysis of the Rindler view of standard AdS/CFT duality on the Poincare patch of AdS, followed by exploiting the simple quotient structure of BTZ which turns the Rindler horizon into the BTZ black hole horizon. While most of our checks are within gravitational effective field theory, we arrive at a fully non-perturbative CFT proposal to probe the UV-sensitive approach to the singularity.

Investigation of sketch interpretation techniques into 2D and 3D conceptual design geometry
Creators: name: Qin, Sheng-Feng
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Interaction and experience design

description: This thesis presents the results of new techniques investigated for applying on-line sketching into 2D and 3D conceptual design geometry throughout a whole development process: data collection, concrete curve segmentation and fitting, 2D geometric constraint extraction and solver, and 3D feature recognition and modelling. This is a new approach. A real time sketch and fuzzy knowledge-based prototype system has been developed in four phases. In the first phase, the segmentation approach investigated accepts the input of on-line free-hand sketch, and segments them into meaningful parts, by using fuzzy knowledge in terms of sketching position, direction, speed and acceleration. During the second phase, a parallel curve classification and identification method is studied by employing fuzzy heuristic knowledge in terms of curve linearity and convexity, in order to quickly classify and identify a variety of 2D shapes including straight lines, circles, arcs, ellipse, elliptical arcs, and free-form curves. Afterwards, a geometric constraint inference engine and a constraint solver are utilised according to degrees of freedom analysis, to capture a designer's intention, to infer geometric constraints simply and automatically, and to generate a possible solution without involving iterative computing. The solver also supports variational geometry in 2D and 3D. In the last phase, rule-based feature interpretation and manipulation techniques are investigated. While drawing, the 2D geometry is accumulated until it can be interpreted as a 3D feature. The feature is then placed in the 3D space and a new feature can be built incrementally upon previous versions. The given examples and case studies show that the system can interpret users' intention on 2D and 3D geometry satisfactorily and effectively. It can not only accept sketched input, but also users' menu-based interactive input of 2D primitives and 3D projections' This mixed automatic feature interpretation and interactive design environment can encourage designers with poor sketching skills to use it for creative design tasks.

description: We identify certain general geometric conditions on a foliation of a spacetime (M,g) by timelike curves that will impede the existence of null geodesic lines, especially if (M,g) possesses a compact Cauchy hypersurface. The absence of such lines, in turn, yields well-known restrictions on the geometry of cosmological spacetimes, in the context of Bartnik's splitting conjecture. Since the (non)existence of null lines is actually a conformally invariant property, such conditions only need to apply for some suitable conformal rescaling of g.

description: We present our current results from ongoing lattice investigations of the Berenstein--Maldacena--Nastase deformation of maximally supersymmetric Yang--Mills quantum mechanics. We focus on the thermal phase structure of this theory, which depends on both the temperature $T$ and the deformation parameter $μ$, through the dimensionless ratios $T / μ$ and $g = λ/ μ^3$ with $λ$ the 't Hooft coupling. We determine the critical $T / μ$ of the confinement transition for couplings $g$ that span three orders of magnitude, to connect weak-coupling perturbative calculations and large-$N$ dual supergravity predictions in the strong-coupling limit. Analyzing multiple lattice sizes up to $N_τ = 24$ and numbers of colors up to $N = 16$ allows initial checks of the large-$N$ continuum limit.

Year: 2022

description: Inference from complex distributions is a common problem in machine learning needed for many Bayesian methods. We propose an efficient, gradient-free method for learning general GMM approximations of multimodal distributions based on recent insights from stochastic search methods. Our method establishes information-geometric trust regions to ensure efficient exploration of the sampling space and stability of the GMM updates, allowing for efficient estimation of multi-variate Gaussian variational distributions. For GMMs, we apply a variational lower bound to decompose the learning objective into sub-problems given by learning the individual mixture components and the coefficients. The number of mixture components is adapted online in order to allow for arbitrary exact approximations. We demonstrate on several domains that we can learn significantly better approximations than competing variational inference methods and that the quality of samples drawn from our approximations is on par with samples created by state-of-the-art MCMC samplers that require significantly more computational resources.

description: We investigate the standard and dual Bondi-Metzner-Sachs (BMS) supertranslation generators on a black hole horizon and draw some conclusions about black hole physics. Recently, it has been shown that in addition to conventional BMS supertranslation symmetries, there exists an additional infinite set of magnetic asymptotic symmetries, dual BMS supertranslations, again parametrized by a function on the two-sphere. We show that the Dirac bracket between these generators exhibits an anomalous central term when one parameter function exhibits a singularity in the complex stereographical coordinates on the sphere. In order to preserve general coordinate invariance, we demonstrate that this central term can be removed by postulating a holographic gravitational Chern-Simons theory on the horizon. This indicates that for an anomaly-free theory of quantum gravity in the presence of a black hole, one should include a boundary theory on the horizon.

An investigation of computer integrated batch manufacturing processes in small and medium-sized enterprises (SMEs)
Creators: name: Si, Thu
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Manufacturing management

description: Global competition and improved manufacturing technologies have resulted in shorter product life cycles and smaller batch production with increasing product variations. Traditional batch manufacturing can never cater efficiently and effectively to the needs of ever changing markets. These changes and problems force small and medium-sized enterprises (SMEs) to look for adaptations and improvements in their manufacturing processes. Larger companies have resources to adapt to these changes, however SMEs face major obstacles such as a lack of finance, technology know-how and expertise. These difficulties are heightened by the fact that current technologies and research are tailored towards larger companies and pay little attention to the demands of SMEs. This research presents an integrated methodology intended specifically to assist SMEs in the design and selection of the most viable batch manufacturing system. The motivation for the research was twofold, firstly there was a need to transfer the advanced batch manufacturing technologies to SMEs through the applications of analytical hierarchy technique (AHP) and computer simulation which are generally used in larger companies, and utilise them effectively in their manufacturing processes. Secondly, the lack of a comprehensive and integrated methodology to deal with the major concerns faced by SMEs in adopting these technologies needed to be addressed. Unlike previous investigations, this study uses an approach which considers all facets of an SME including organisational, tactical, operational and financial issues. It attempts to address the complex problems of manufacturing system design by integrating a decision framework with the group technology concept and powerful computer tools. This is accomplished by the use of multi-criteria decision making, Group Technology, computer simulation and costs modelling tools and techniques. To validate the suitability of the methodology, an industrial case study with an SME engaged in discrete batch manufacturing was used. The results indicate that the research methodology is effective and useful for a number of reasons. Firstly, it is a generic system and can be tailored to fit the uniqueness of any SME. Also, it will assist in helping SMEs to understand the advanced technologies, ease the decision making process, facilitate the effective integration of information and the decision making process, reduce investment risks, and eventually achieve the introduction of a much needed "low cost system" to improve the competitiveness of manufacturing companies.

Whilst, condensation of spin-triplet excitons is a promising frontier because spin supercurrent and spin-Seebeck effects will be observable. A canonical cobaltite LaCoO$_{3}$ under very high magnetic fields is a propitious candidate, yet to be verified. Here, we unveil the exotic phase diagram of LaCoO$_{3}$ up to 600 T generated using the electromagnetic flux compression method and the state-of-the-art magnetostriction gauge. We found the continuous magnetostriction curves and a bending structure, which suggest the emergence of two distinct spin-triplet exciton condensates. By constructing a phenomenological model, we showed that quantum fluctuations of excitons are crucial for the field-induced successive transitions. The spin-triplet exciton condensation in a cobaltite, which is three-dimensional and thermally equilibrated, opens up a novel venue for spintronics technologies with spin-supercurrent such as a spin Josephson junction.

description: The scotogenic model of neutrino mass is modified so that the dark Majorana fermion singlet $S$ which makes the neutrino massive is itself generated in one loop. This is accomplished by having $Z_6$ lepton symmetry softly broken to $Z_2$ in the scalar sector by a unique quadratic term. It is shown that $S$ is a viable freeze-in dark-matter candidate through Higgs decay.

description: In this paper we consider the Universe at the late stage of its evolution and deep inside the cell of uniformity. At these scales, the Universe is filled with inhomogeneously distributed discrete structures (galaxies, groups and clusters of galaxies). Supposing that a small fraction of colored objects escaped hadronization and survived up to now in the form of quark-gluon nuggets (QNs), and also taking into account radiation, we investigate scalar perturbations of the FRW metrics due to inhomogeneities of dustlike matter as well as fluctuations of QNs and radiation. In particular, we demonstrate that the nonrelativistic gravitational potential is defined by the distribution of inhomogeneities/fluctuations of both dustlike matter and QNs. Consequently, QNs can be distributed around the baryonic inhomogeneities (e.g., galaxies) in such a way that it can solve the problem of the flatness of the rotation curves. We also show that the fluctuations of radiation are caused by both the inhomogeneities in the form of galaxies and the fluctuations of quark-gluon nuggets. Therefore, if QNs exist, the CMB anisotropy should contain also the contributions from QNs. Additionally, the spatial distribution of the radiation fluctuations is defined by the gravitational potential. All these results look physically reasonable.

description: Technique selection is fundamentaltoWomen’s Artistic Gymnastics with rapidly evolving difficulty and complexity; a result of changes in the scoring system and apparatus design. The aim of this research was to increase knowledge and understanding of the biomechanics underpinning female longswing techniques to determine effective technique selection. Five progressive themes addressed this aim; contemporary trend analysis, biomechanical conceptual approach, method validation, biomechanical musculoskeletal approach and biomechanical energeticapproach. Elite competition provided the basis to the thesis with a strongecologicallyvalid trend analysis reporting the straddle Tkachev as the most frequently performed release skill preceded by three distinct longswing techniques; arch, straddle, pike. Quantifying each technique through a biomechanical conceptual approach enumerated differences observed and examined their influence on key release parameters. Significant differences (p≤0.05) were reported in the initiation and joint angular kinematics within the functional phases; however not for release parameters. Further examination into the joint kinetics and energetic demands of the gymnast were required to explain technique selection. Non-invasive methods of joint kinetic data collection are challengingwithin the elite competitiveenvironment; therefore indirect methods were validated to provide confidence in the subsequent musculoskeletal approach. Inverse dynamic estimations were most sensitive to kinematic inputs with field versus lab comparisons highlighting systematic differences in joint moments (0.8%RMSD in consistency). Joint kinetics provided new knowledge of the underlying biomechanics of varying techniques, specifically greater shoulder joint moments and hip joint powers during the pike longswing. Examining gymnast energetic contribution to the total gymnast-high-bar energy system developed anoveleffectiveness score highlighting the potential energy excess available to the arch (30%) and straddle (2%) techniques, indicating the potential to develop more complex versions of skills. This research providescoaches and scientists with specificphysical preparation requirements for varying longswing techniques and insight into the need for customised technique selection.

description: Gravitational-wave observations in the near future may allow us to measure tidal deformabilities of neutron stars, which leads us to the understanding of physics at nuclear density. In principle, the gravitational waveform depends on various tidal parameters, which correlate strongly. Therefore, it would be useful if one can express such tidal parameters with a single parameter. Here, we report on universal relations among various $\ell$-th (dimensionless) electric, magnetic and shape tidal deformabilities in neutron stars and quark stars that do not depend sensitively on the equation of state. Such relations allow us to break the degeneracy among the tidal parameters. In this paper, we focus on gravitational waves from non-spinning neutron-star binary inspirals. We first derive the leading contribution of the $\ell$-th electric and $\ell=2$ magnetic tidal deformabilities to the gravitational-wave phase, which enters at $2\ell +1$ and $6$ post-Newtonian orders relative to the leading Newtonian one respectively. We then calculate the useful number of gravitational-wave cycles and show that not only the $\ell=2$ but also $\ell=3$ electric tidal deformabilities are important for parameter estimation with third-generation gravitational-wave detectors such as LIGO III and Einstein Telescope. Although the correlation between the $\ell=2$ and $\ell=3$ electric tidal deformabilities deteriorate the measurement accuracy of the former deformability parameter, one can increase its measurement accuracy significantly by using the universal relation. We provide a fitting formula for the LIGO III noise curve in the Appendix.

description: Let k be a field with cohomological dimension less than 3; we call such fields low-dimensional. Examples include algebraically closed fields, finite fields and function fields thereof, local fields, and number fields with no real embeddings. We determine the 1-column of the motivic Adams-Novikov spectral sequence over k. Combined with rational information we use this to compute the first stable motivic homotopy group of the sphere spectrum over k. Our main result affirms Morel's pi_1-conjecture in the case of low-dimensional fields. We also determine stable motivic pi_1 in integer weights other than -2, -3, and -4.

description: Depinning of nanoscale magnetic textures, such as domain walls, vortices and skyrmions, is of paramount importance for magnetic storage and information processing. We measure time-resolved magnetic switching statistics of an individual, non-single-domain Fe$_3$O$_4$ nanoparticle using a micrometer-scale superconducting quantum interference device. Surprisingly, a strong narrowing of the waiting-time distributions before reaching the final state is observed as compared to the exponential distribution expected for a single barrier. The magnetization reversal across the nanostructure is thus shown to result from multiple serial barriers in the minimum energy pathway.
