description: Surveillance statistics show that many food poisoning cases occur in the home and surveys have revealed wide spread ignorance of cross-contamination and temperature control. In this work the food preparation practices of children and young adults (n=267) in south East wales were considered. Regular food preparation was found to occur from age 11 and the most common practices were sandwich and snack making. Sources of information about food hygiene were highlighted and the role of schools in the provision of food hygiene information was considered. Ninety eight teachers responded and of these 86% of Primary school teachers and all secondary schoolteachers surveyed claimed they taught food hygiene, with the skill considered most important by the majority of teachers being hand washing. The relationship between food hygiene and psychological precursors of behaviour was investigated. The data regarding food preparation practices was collated and was used to inform the construction of a questionnaire based on the Theory of Reasoned Action. The beliefs used in the construction of the questionnaire were obtained from a sample (n=438) and the most common beliefs about what they could do to keep food safe to eat included 'cook food properly', 'wash hands' and 'check the best before date'. Using self report measures (n=267) a significant correlation was recorded (Î²=0.42) and further, attitude, subjective norm and intention explained 51% of the variance in behaviour. However, using observations (n=30) the relationship was not found to be significant (Î²=0.03) and attitude, subjective norm and intention explained only 8% of the variance in behaviour. The implications of this in terms both of food hygiene and the Theory of Reasoned Action were considered.

description: In crystalline materials, electron-phonon coupling (EPC) is a ubiquitous many-body interaction that drives conventional Bardeen-Cooper-Schrieffer superconductivity. Recently, in a new kagome metal $\rm{CsV_3Sb_5}$, superconductivity that possibly intertwines with time-reversal and spatial symmetry-breaking orders is observed. Density functional theory calculations predicted weak EPC strength,$λ$, supporting an unconventional pairing mechanism in $\rm{CsV_3Sb_5}$. However, experimental determination of $λ$ is still missing, hindering a microscopic understanding of the intertwined ground state of $\rm{CsV_3Sb_5}$. Here, using 7-eV laser-based angle-resolved photoemission spectroscopy and Eliashberg function analysis, we determine an intermediate $λ$=0.45~0.6 at T=6 K for both Sb 5p and V 3d electronic bands, which can support a conventional superconducting transition temperature on the same magnitude of experimental value in $\rm{CsV_3Sb_5}$. Remarkably, the EPC on the V 3d-band enhances to $λ$~0.75 as the superconducting transition temperature elevated to 4.4 K in $\rm{Cs(V_{0.93}Nb_{0.07})_3Sb_5}$. Our results provide an important clue to understand the pairing mechanism in the Kagome superconductor $\rm{CsV_3Sb_5}$.

Higher spin fields with reversed spin-statistics relation

Year: 2013
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: A construction of massive free fields with arbitrary spin and reversed spin-statistics relation is presented. The main idea of the construction is to consider fields that transform according to representations of the Lorentz group that are doubled in comparison with the representations according to which normal (physical) fields transform. This allows the definition of opposite commutation properties for these fields, while the spin of the particles they describe remains unchanged. The correspondence established by the construction between fields obeying normal and reversed spin-statistics relation makes it possible to express e.g. the polarization states, (anti)commutators, or Feynman propagators of the latter fields in terms of those of the normal fields to which they correspond. The cases of the scalar and Dirac fields are discussed in additional detail.

description: The Hyper-Kamiokande (HyperK) experiment is expected to precisely measure the Diffuse Supernova Neutrino Background (DSNB). This requires that the backgrounds in the relevant energy range are well understood. One possible background that has not been considered thus far is the annihilation of low-mass dark matter (DM) to neutrinos. We conduct simulations of the DSNB signal and backgrounds in HyperK, and quantify the extent to which DM annihilation products can pollute the DSNB signal. We find that the presence of DM could affect the determination of the correct values of parameters of interest for DSNB physics, such as effective neutrino temperatures and star formation rates. While this opens the possibility of simultaneously characterising the DNSB and discovering dark matter via indirect detection, we argue that it would be hard to disentangle the two contributions due to the lack of angular information available at low energies.

description: Gravitational waves from the coalescences of black hole and neutron stars afford us the unique opportunity to determine the sources' properties, such as their masses and spins, with unprecedented accuracy. To do so, however, theoretical models of the emitted signal that are i) extremely accurate and ii) computationally highly efficient are necessary. The inclusion of more detailed physics such as higher-order multipoles and relativistic spin-induced orbital precession increases the complexity and hence also computational cost of waveform models, which presents a severe bottleneck to the parameter inference problem. A popular method to generate waveforms more efficiently is to build a fast surrogate model of a slower one. In this paper, we show that traditional surrogate modelling methods combined with artificial neural networks can be used to build a computationally highly efficient while still accurate emulation of multipolar time-domain waveform models of precessing binary black holes. We apply this method to the state-of-the-art waveform model SEOBNRv4PHM and find significant computational improvements: On a traditional CPU, the typical generation of a single waveform using our neural network surrogate SEOBNN_v4PHM_4dq2 takes 18ms for a binary black hole with a total mass of $44 M_{\odot}$ when generated from 20Hz. In comparison to SEOBNRv4PHM itself, this amounts to an improvement in computational efficiency by two orders of magnitude. Utilising additional GPU acceleration, we find that this speed-up can be increased further with the generation of batches of waveforms simultaneously. Even without additional GPU acceleration, this dramatic decrease in waveform generation cost can reduce the inference timescale from weeks to hours.

This has been done by analyzing the effects of deformed Heisenberg algebra on nanowires and nanotubes. We first deform the Schrodinger equation with cylindrical topology. Then specific solutions to the deformed Schrodinger equation with different boundary conditions are studied. These deformed solutions are used to investigate the consequences of the deformation on the energy of nanowires and nanotubes.

description: We unveil nontrivial topological properties of zero-temperature magnetization plateau states in periodically modulated quantum spin chains under a uniform magnetic field. As positions of plateaus are uniquely determined by the modulation period of exchange couplings, we find that the topologically nontrivial plateau state can be characterized by a nonzero integer Chern number and has nontrivial edge excitations. Our study clarifies the topological origin of the well-known phenomena of quantized magnetization plateaus in one-dimensional quantum spin systems and relates the plateau state to the correlated topological insulator.

The Role and Power of Stakeholders in Branding Post-Mature Destinations: A Case Study of Calella
Creators: name: Pérez, Zaida Rodrigo
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Tourism marketing

description: The main aim of this thesis is to explore the relevance of destination branding strategies for destinations in decline and to identify the role of stakeholders in those strategies through a case study of Calella in the Costa de Barcelona- Maresme, Spain. Five research objectives, encompassing a critique of relevant literature, conceptual discussion and empirical research, assist in accomplishing the overall aim. Key concepts that underpin the study are: the role and power of stakeholders and stakeholder management in destination management; the TALC; destination regeneration strategies; destination branding. The study adopts a case study approach, employing four main types of complementary sources: semi- structured interviews, structured interviews, archives and personal observations. The findings provide empirical evidence highlighting that a positive place image is a necessity for an effective destination brand and that stakeholder involvement is paramount for the successful development of destination branding strategies. In the case study destination of Calella it emerges that there is a mismatch between the expectations of stakeholders in the private and public sectors, where the former seem uninterested in adopting a holistic approach and prioritise their own personal business goals - even if these are contrary to the interests of the wider resort community. In addition, there is little community involvement or representation in local decision-making and strategy development. These findings have practical implications for the tourism industry, specifically for post-mature seaside resorts and especially for Calella itself. Recommendations include: enhancing the effective involvement of stakeholders in destination management decisions to increase 'buy-in', 'ownership' and 'self-identification' with marketing and branding strategies.

description: We investigate the thermoelectric properties of a hybrid nanodevice composed by a 2D carbon based material and a superconductor. This system presents nonlinear bipolar thermoelectricity as induced by the spontaneous breaking of the Particle-Hole (PH) symmetry in a tunnel junction between a BiLayer Graphene (BLG) and a Bardeen-Cooper-Schrieffer (BCS) superconductor. In this scheme, the nonlinear thermoelectric effect, predicted and observed in SIS' junctions is not affected by the competitive effect of the Josephson coupling. From a fundamental perspective, the most intriguing feature of this effect is its bipolarity. The capability to open and control the BLG gap guarantees improved thermoelectric performances, that reach up to 1 mV/K regarding the Seebeck coefficient and a power density of 1 nW/$μ$m$^2$ for temperature gradients of tens of Kelvins. Furthermore, the externally controlled gating can also dope the BLG, which is otherwise intrinsically PH symmetric, giving us the opportunity to investigate the bipolar thermoelectricity even in presence of a controlled suppression of the PH symmetry. The predicted robustness of this system could foster further experimental investigations and applications in the near future, thanks to the available techniques of nano-fabrication.

description: In this paper, we undertake the error analysis of the time discretization of systems of Forward-Backward Stochastic Differential Equations (FBSDEs) with drivers having polynomial growth and that are also monotone in the state variable. We show with a counter-example that the natural explicit Euler scheme may diverge, unlike in the canonical Lipschitz driver case. This is due to the lack of a certain stability property of the Euler scheme which is essential to obtain convergence. However, a thorough analysis of the family of $θ$-schemes reveals that this required stability property can be recovered if the scheme is sufficiently implicit. As a by-product of our analysis, we shed some light on higher order approximation schemes for FBSDEs under non-Lipschitz condition. We then return to fully explicit schemes and show that an appropriately tamed version of the explicit Euler scheme enjoys the required stability property and as a consequence converges. In order to establish convergence of the several discretizations, we extend the canonical path- and first-order variational regularity results to FBSDEs with polynomial growth drivers which are also monotone. These results are of independent interest for the theory of FBSDEs.

description: This thesis investigates the novel use of paper and Tyvek sterilisation pouches as containment systems to perform various applications of freeze-drying. Their effect on the freeze-drying of a pharmaceutical protein, mass and heat transfer, sterile freeze-drying and containment of microorganisms were examined. Ovine derived Immunoglobulin G (IgG) specific for fluorescein was used as a model biopharmaceutical protein and a range of assays developed to quantify its biological activity, aggregation, turbidity, residual moisture and reconstitution time. IgG was formulated using different carbohydrates and analysed using freeze-drying microscopy to allow precise development of optimum freeze-drying cycles. The IgG was freeze-dried using these cycles and the function and structure of the IgG was shown to be unaffected. Freeze-drying cycles were modified to investigate the effect paper and Tyvek pouches had on the IgG which showed no change in activity or structure. However, pouches decreased sublimation rates and increased process time. Resistance to water vapour, and the subsequent effect on mass and heat transfer during the freeze-drying process, imposed by paper and Tyvek sterilisation pouches, Gore Lyoguard, product dry layer and freeze-drying stoppers were investigated. Pouches presented greater resistance to water vapour movement than the dry product layer, Lyoguard and stoppers. Increasing resistance decreases mass transfer, increases pressure inside the pouches thereby increasing the heat transfer coefficient. A process simulation using nutrient rich media was performed where vials were packaged aseptically and transported to a freeze-drier in a normal laboratory environment. The vials showed no growth of contaminating microorganisms after incubation. In addition, pouches containing nutrient rich media were challenged with aerosolised Saccharomyces cerevisiae and also showed no growth of contaminating microorganisms after incubation. Finally, pouches were demonstrated to be able to contain Escherichia coli during freeze-drying thus preventing contamination of the freeze-drier and the environment.

description: General extensions of General Relativity (GR) based on bona fide degrees of freedom predict a fifth force which operates within massive objects, opening up an exciting opportunity to perform precision tests of gravity at stellar scales. Here, focusing on general scalar-tensor theories for dark energy, we utilize the Sun as our laboratory and search for imprints of the fifth-force effect on the solar equilibrium structure. With analytic results and numerical simulations, we explain how the different solar regions offer powerful ways to test gravity. Accounting for the delicate interplay between fifth force and solar microphysics such as opacity, diffusion, equation of state and metallicity, we demonstrate that the fifth force still leaves a sharp signature on the solar sound speed, in a region where simple estimates of input physics uncertainties become negligible. For general scalar-field extensions of GR, known as (U-)DHOST, based solely on the observational helioseismic errors, our analysis at the equilibrium level allows to place an approximate constraint on the fifth-force coupling strength of $-10^{-3} \lesssim \mathcal{Y} \lesssim 5\cdot 10^{-4}$ at $2σ$. This result improves previous stellar constraints by $\sim 3$ orders of magnitude, and should be confirmed and improved by future helioseismic inversions in modified gravity combined with an elaborate accounting of theoretical uncertainties. Our analysis can be applied to a wide set of theories beyond GR, and also paves the way for helioseismic analyses in this context. In this regard, we discuss how the solar radiative and convective zone can be employed as promising laboratories to test generic theories of gravity.

description: We propose a nonlinear acoustic metasurface concept by exploiting the nonlinearity of the locally resonant unit cells formed by curved beams. The analytical model is established to explore the nonlinear phenomenon, specifically the second-harmonic generation (SHG) of the acoustic waveguide and validated through numerical and experimental studies. Novel nonlinear acoustic metasurfaces are developed to demultiplex different frequency components and achieve anomalous wavefront control of SHG in the transmitted region. To this end, we demonstrate wave steering, wave focusing, and self-bending propagation. Our results show that the proposed nonlinear metasurface provides an effective and efficient platform to achieve significant SHG, and separate different harmonic components for wavefront control of individual harmonics. Overall, this study offers new avenues to harness nonlinear effects for acoustic wavefront tailoring and develops new potential toward advanced technologies to manipulate acoustic waves.

description: Inspired by the recent measurement of $CP$ asymmetry in the individual mode on LHCb, we study $CP$ asymmetry of the $D\to ππ$ system in the isospin and topological analysis. The ratio between penguin and tree amplitudes $P/(T+C)$ in the $D\to ππ$ system is found to be greater than two in most values of the relative strong phase. And $D^0\to π^0π^0$ is a potential mode to reveal the $CP$ asymmetry of the order of $10^{-3}$, which would be observed by Belle II in the future. The large $CP$ asymmetry in the $D\to ππ$ system might be understood in the $t$-channel final-state interaction.

description: We study $O(d)$-equivariant biharmonic maps in the critical dimension. A major consequence of our study concerns the corresponding heat flow. More precisely, we prove that blowup occurs in the biharmonic map heat flow from $B^4(0, 1)$ into $S^4$. To our knowledge, this was the first example of blowup for the biharmonic map heat flow. Such results have been hard to prove, due to the inapplicability of the maximum principle in the biharmonic case. Furthermore, we classify the possible $O(4)$-equivariant biharmonic maps from $\mathbf{R}^4$ into $S^4$, and we show that there exists, in contrast to the harmonic map analogue, equivariant biharmonic maps from $B^4(0,1)$ into $S^4$ that wind around $S^4$ as many times as we wish. We believe that the ideas developed herein could be useful in the study of other higher-order parabolic equations.

description: Foam film’s properties have a high impact on the properties of the macroscopic foams. This work focusses on protein stabilized foam films. The direct comparison of three different proteins with a concentration normalized to the protein surface enables to distinguish between electrostatic, steric and network stabilization effects. In order to untangle those effects, we study and compare two globular proteins (β − lactoglobulin, BLG, and bovine serum albumin, BSA) and a disordered, flexible protein (whole casein, CN) at low ionic strengths with varying solution pH. Image intensity measurement as a recently developed image analysis method in this field allows to record spatially resolved disjoining pressure isotherms in a Thin Film Pressure Balance (TFPB). This reveals insights into the structure formation in inhomogeneous protein films. As a novel method we introduce tracking inhomogeneities (features) which enables the measurement of interfacial mobility and stiffness of foam films. Around the isoelectric point (IEP), Newton Black Films (NBF) form which are stable for the globular proteins while they are unstable for the disordered flexible one. This difference in film stability is explained by different characteristics of the network structures which is supported by findings in the bulk and at the surface of the respective protein solutions.
Risk Perception and Safety Practices; the Implications for Safety Initiatives and Incident Prevention in an Outdoor Adventure Activity
Creators: name: Powell, Colin
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Occupational and workplace health and safety

description: Participation in outdoor adventure activities can result in injuries, medical conditions and fatalities. Whilst risk is present in outdoor adventure, the literature indicates that engagement with risk is often desired and results in valued outcomes. The way in which risk is perceived and responded to has been described as being linked to a range of socio-psychological variables. These variables may act as a filter to messages that are designed to promote safety and reduce incidents. This thesis proposes that an understanding of participantsâ€™ knowledge, beliefs, and experience and the meaning of an activity to them, can support the development of approaches to the promotion of safety that have contextual relevance. Using participant centred methods, this research aimed to generate recommendations to inform the development of safety initiatives and incident prevention strategies associated with an outdoor adventure activity. Kayaking in the sea environment was used as a case study. Questionnaires administered to individuals who use kayaks in the sea, identified a range of health impacts, perceived cause and safety practices. Variation in response was noted according to the type of kayak used, activities undertaken and characteristics of respondents. These findings, together with the results of an observational study and issues identified in the review of the literature, were used to generate themes to be explored in semi-structured interviews with interviewees who used different types of kayaks and varied in experience and immersion in the activity. The interviews identified a range of motives for participation and illuminated the meaning of risk to participants. Socio-psychological factors influencing both their own and others perception, assessment and response to risk were described. The interviewees proposed measures to enhance safety; these focused upon education, training, planning and preparation. The quantitative and qualitative findings were utilised to generate specific recommendations that could inform safety initiatives and incident prevention strategies linked to kayaking. Broad themes identified in the recommendations were regarded as being of relevance to other voluntary risk taking activities. It is concluded that there is a need to recognise that there are different reasons for engaging with risk and that within a broad activity, there are likely to be differential experiences of risk. On the basis of this, it is proposed that a generic approach to the management of risk may be inappropriate; it is advocated that there is a need to target safety initiatives and incident prevention strategies at particular subgroups of participants and for safety guidance to be context specific.

The study evaluates the effect of a whole school intervention based upon the implementation of school nutrition action groups in two secondary schools in South Wales. The study explores the impact of the intervention on food sales, pupil food choices, knowledge and attitude. Foods provided during the school day can make significant contribution to meeting the dietary requirements of children and adolescents (Crawley, 2005c) and it is estimated that the midday school meal may account for at least 33% of daily energy intake (Crawley, 2005b). This chapter sets the backdrop and context to this work and describes the provision of school meals in UK and westernised countries. As well as considering a contemporary perspective, the chapter describes the historical development of school meals service in UK in order to understand the barriers and motivators to the movement for change in school meal provision. The chapter explores the role of government priority and investment and describes the development of national food strategies, particularly Appetite for Life in Wales. These strategies, implemented via food and nutrient based standards, aim to positively impact on school meals and adolescent health.

description: Using an almost complete relativistic method based on the Bethe-Salpeter equation, we study the mixing angle $θ$, the mass splitting $\bigtriangleup M$, the strong decay widths $Γ(D^{({\prime})}_1)$ and the weak production rates $Br(B\to D^{({\prime})}_1\ellν_{\ell})$ of the $D_1(2420)$ and $D_1^{\prime}(2430)$. We find there is the strong cancellation between the $^1P_1$ and $^3P_1$ partial waves in $D_1^{\prime}(2430)$ with $θ\sim-35.3^{\circ}$, which leads to the `$1/2$ vs $3/2$' puzzle. The puzzle can not be overcome by adding only relativistic corrections since in a large parameter range where $\bigtriangleup M$ is linear varying and not small, the $θ$, $Γ(D^{({\prime})}_1)$ and $Br(B\to D^{({\prime})}_1\ellν_{\ell})$ remain almost unchanged but conflict with data. While in a special range around the mass inverse point where $\bigtriangleup M=0$ and $θ=\pm 90^{\circ}$, they change rapidly but we find the windows where $\bigtriangleup M$, $Γ(D^{({\prime})}_1)$ and $Br(B\to D^{({\prime})}_1\ellν_{\ell})$ are all consistent with data. The small $\bigtriangleup M$ confirmed by experiment, is crucial to solve the `$1/2$ vs $3/2$' puzzle.

Many-body quantum chaos and emergence of Ginibre ensemble

description: We show that non-Hermitian Ginibre random matrix behaviors emerge in spatially-extended many-body quantum chaotic systems in the space direction, just as Hermitian random matrix behaviors emerge in chaotic systems in the time direction. Starting with translational invariant models, which can be associated with dual transfer matrices with complex-valued spectra, we show that the linear ramp of the spectral form factor necessitates that the dual spectra have non-trivial correlations, which in fact fall under the universality class of the Ginibre ensemble, demonstrated by computing the level spacing distribution and the dissipative spectral form factor. As a result of this connection, the exact spectral form factor for the Ginibre ensemble can be used to universally describe the spectral form factor for translational invariant many-body quantum chaotic systems in the scaling limit where $t$ and $L$ are large, while the ratio between $L$ and $L_{\mathrm{Th}}$, the many-body Thouless length is fixed. With appropriate variations of Ginibre models, we analytically demonstrate that our claim generalizes to models without translational invariance as well. The emergence of the Ginibre ensemble is a genuine consequence of the strongly interacting and spatially extended nature of the quantum chaotic systems we consider, unlike the traditional emergence of Hermitian random matrix ensembles.

description: Topological Kondo insulators have been attracting great attention from the condensed-matter physics community due to their fascinating topological and strongly correlated properties. Here, we report angle-dependent c-axis magnetoresistance (MR) oscillations in a Kondo insulator, SmB6 single crystal, in a magnetic field of up to 13 T rotated in the ab-plane. Four-fold symmetric MR oscillations are first observed above 8 K, which result from the four-fold (C4) degeneracy of the bulk Fermi surface of SmB6. With decreasing temperature down to 2.3 K, the C4 symmetry of the MR oscillations gradually weakens and C2 symmetry appears. This demonstrates a crossover from three-dimensional bulk states to two-dimensional surface states and implies the possible emergence of topological nematic states. Our experimental observations shed new light on the metallic surface states and nematic states in the Kondo insulator SmB6.

description: Current AI systems are designed to solve close-world problems with the assumption that the underlying world is remaining more or less the same. However, when dealing with real-world problems such assumptions can be invalid as sudden and unexpected changes can occur. To effectively deploy AI-powered systems in the real world, AI systems should be able to deal with open-world novelty quickly. Inevitably, dealing with open-world novelty raises an important question of novelty difficulty. Knowing whether one novelty is harder to deal with than another, can help researchers to train their systems systematically. In addition, it can also serve as a measurement of the performance of novelty robust AI systems. In this paper, we propose to define the novelty reaction difficulty as a relative difficulty of performing the known task after the introduction of the novelty. We propose a universal method that can be applied to approximate the difficulty. We present the approximations of the difficulty using our method and show how it aligns with the results of the evaluation of AI agents designed to deal with novelty.

Does State of Being and Dynamic Movement have a relationship with Creativity?

Publisher: name: Cardiff Metropolitan University

Subjects: Art theory

description: Creativity research is a fast growing area of research. In our modern society there is recognition that creativity is becoming more and more important (Adobe Survey, 2012). David Bohm and David Peat applied a universal approach to explaining creativity. Peat and Bohm explain the movement that occurs in the creative process by way of intrinsic and generative orders. They also highlight the importance of 'state of being' and an interaction both externally and internally of a person in the creative process. Mihaly Csikszentmihalyi, who is a well-respected modern researcher of creativity, also includes aspects of state of being in his flow concept, as well as pointing out the importance of interaction and feedback from an external world. This doctoral research series is based on three main factors - my 15-year self-study as a practising artist, an analysis of contemporary creativity and mind theories and empirically testing the key propositions that arise from these analyses in eight seperate studies. The research explores whether there is a relationship between 'state of being', 'dynamic movement' and creativity. The contribution to knowledge are clear definitions of 'state of being' and 'dynamic movement' and a practical application of these terms in the context of creativity. The methodology used to empirically explore the relationship of these propositions could also be regarded as a contribution to knowledge as it extends the triangulation metholology to include 'dynamic movement'. The results from the eight studies start to show a relationship between 'state of being', 'dynamic movement' and creativity.

Asymptotic entanglement transformation between W and GHZ states

description: We investigate entanglement transformations with stochastic local operations and classical communication (SLOCC) in an asymptotic setting using the concepts of degeneration and border rank of tensors from algebraic complexity theory. Results well-known in that field imply that GHZ states can be transformed into W states at rate 1 for any number of parties. As a generalization, we find that the asymptotic conversion rate from GHZ states to Dicke states is bounded as the number of subsystems increase and the number of excitations is fixed. By generalizing constructions of Coppersmith and Winograd and by using monotones introduced by Strassen we also compute the conversion rate from W to GHZ states.
