description: In this work we propose a mechanism for converting the spectral problem of vertex models transfer matrices into the solution of certain linear partial differential equations. This mechanism is illustrated for the $U_q[\widehat{\mathfrak{sl}}(2)]$ invariant six-vertex model and the resulting partial differential equation is studied for particular values of the lattice length.

description: In this paper, we present new quasi-interpolating spline schemes defined on 3D bounded domains, based on trivariate $C^2$ quartic box splines on type-6 tetrahedral partitions and with approximation order four. Such methods can be used for the reconstruction of gridded volume data. More precisely, we propose near-best quasi-interpolants, i.e. with coefficient functionals obtained by imposing the exactness of the quasi-interpolants on the space of polynomials of total degree three and minimizing an upper bound for their infinity norm. In case of bounded domains the main problem consists in the construction of the coefficient functionals associated with boundary generators (i.e. generators with supports not completely inside the domain), so that the functionals involve data points inside or on the boundary of the domain. We give norm and error estimates and we present some numerical tests, illustrating the approximation properties of the proposed quasi-interpolants, and comparisons with other known spline methods. Some applications with real world volume data are also provided.

description: El incremento en el consumo de energía, sigue siendo un indicador determinante del desarrollo de la sociedad y los mercados a nivel mundial. La generación y uso de la energía son algunos de los mayores retos tecnológicos actuales debido a que más del 50 % proviene de fuentes no renovables derivadas del petróleo y su impacto en el ambiente no permite su sostenibilidad a lo largo del tiempo. Por esta razón, se han implementado diferentes estrategias, planes y políticas a nivel mundial para incentivar la diversificación de las fuentes, los vectores energéticos, el aumento la eficiencia energética, y avance hacia estrategias de uso eficiente de la energía, lo que permitiría un desarrollo sostenible en el ámbito energético. Con este estudio se determinó el panorama de oportunidades alineado con la sostenibilidad y la transición energética en Colombia para sistemas híbridos de generación eléctrica, utilizando el hidrógeno como vector energético para el almacenamiento y transporte de energía, además de permitir la integración de fuentes de generación disponibles y las propuestas. Como resultado del análisis, se concluye que tenemos una gran oportunidad para aprovechar la diversidad de nuestra matriz energética, las políticas estatales y el momento de cambio que estamos experimentando como especie

description: Quantum squeezing in mechanical systems is not only a key signature of macroscopic quantum effects, but can also be utilized to advance the metrology of weak forces. Here we show that strong mechanical squeezing in the steady state can be generated in an optomechanical system with mechanical nonlinearity and red-detuned monochromatic driving on the cavity mode. The squeezing is achieved as the joint effect of nonlinearity-induced parametric amplification and cavity cooling, and is robust against thermal fluctuations of the mechanical mode.

description: The contamination of wastewater by microplastic particles (MPs) is anunresolved environmental problem. In order to resolve this problem, aconcept is developed for the microbial remediation of MPs. To realize thisconcept, degradable block copolymers are required, which adhere on MPsurfaces and contain segments of carbohydrate moieties (here galactose) forthe attraction of degrading microbes and accelerated biofilm formation.Therefore, in this study, a versatile synthesis route for amphiphiliccarbohydrate block copolymers from poly(d,l-lactic acid) (PLA) and galactosemoieties is presented. The properties of the block copolymers are investigatedby thermal analysis, as well as regarding their colloidal properties, theiradhesion behavior on MP surfaces, and their potential for support ofmicrobial growth (usingLacticaseibacillus zeae).

description: In this paper, we consider the joint opportunistic routing and channel assignment problem in multi-channel multi-radio (MCMR) cognitive radio networks (CRNs) for improving aggregate throughput of the secondary users. We first present the nonlinear programming optimization model for this joint problem, taking into account the feature of CRNs-channel uncertainty. Then considering the queue state of a node, we propose a new scheme to select proper forwarding candidates for opportunistic routing. Furthermore, a new algorithm for calculating the forwarding probability of any packet at a node is proposed, which is used to calculate how many packets a forwarder should send, so that the duplicate transmission can be reduced compared with MAC-independent opportunistic routing & encoding (MORE) [11]. Our numerical results show that the proposed scheme performs significantly better that traditional routing and opportunistic routing in which channel assignment strategy is employed.

description: Zinc oxide nanoparticles (ZnO NPs) present multiple applications due to their
 special physico-chemical and antimicrobial properties. Moreover, they are
 inexpensive and less cytotoxic than other metal nanoparticles. The increasing
 use of the ZnO NPs in different sectors has raised concerns about their
 potential risks for the workers, consumers and the environment. The posible toxic effects of different zinc oxide nanomaterials
 (G-ZnO, ZnO and ZnO:Mn) on the respiratory system and their irritant
 potential were evaluated. The antimicrobial activity of G-ZnO, ZnO and ZnO:Mn was analysed against
 Gram positive (methicillin-resistant S. aureus and vancomycin-resistant E.
 faecium) and Gram negative (A. baumannii and P. aeruginosa) bacteria.

description: Integrability of electron dynamics in one dimension is manifested by the non-equilibrium stationary states. They emerge near a point contact coupling two quantum Hall edges with different chemical potentials. I use the non-equilibrium bosonization technique to show that the effective temperature of such states at the fractional quantum Hall edges has a universal linear dependence on the current through the contact. In contrast, the temperature at eventual equilibrium scales as the square root of the power dissipating at the point contact. I propose to use this distinction to detect these intriguing non-equilibrium states.

title: Re-'Cycling' Poetry: Structure in the Twentieth-Century English Song Cycle
Creators: name: Burton, Natalie
Publisher: name: The Open University
Year: 2023

description: The genre of song cycle is characterized by significant typological variety and ambiguity, to the extent that a concise working definition of the form doesn’t really exist. This complexity is partly grounded in the historical legacy of the loaded term ‘cycle’ and its inherent connotations of circular succession. Influenced by this notion, much song cycle discourse is underpinned, consciously or unconsciously, by assumptions of unity, on a variety of musical and textual levels, that have typically pointed to the success or failure of works as cycles.

 This study seeks to explore several interrelated ideological, methodological and critical strands. Firstly, established singular conceptions of song cycle structure limit the interpretative possibilities available to analysts and performers. Clearly, not all cycles are circles and an openness to alternative patterns, shapes and structures makes space for new understandings of existing works. Secondly, the breadth and diversity of the song cycle repertory requires bespoke methodological approaches that respond to the specific conceptual and contextual circumstances of works and composers to provide the fullest possible account of their potential structure(s). Finally, the intermedial nature of the song cycle demands a sustained and equal preoccupation with both words and music. Close analysis of music and text that is provisional and dynamic provides an effective way of exploring issues of structure.

 The repertory of English, twentieth-century song cycles is relatively underrepresented in musicological study. Finzi, Vaughan Williams and Ireland are all well-known composers, yet very little scholarship focuses on their song cycles. Informed by the principles outlined, I argue that the structure of Vaughan Williams’s On Wenlock Edge can be understood as three, paired micro-narratives, that the structure of Finzi’s Earth and Air and Rain is dynamic (having both framing and internal narrative cycle structures) and that the structure of Ireland’s Mother and Child is non-linear and determined by experiential qualities.

description: Southeast Asian Neochrysocharis formosa
 Southeast Asian specimens of N. formosa differ from typical European species in having the coxae dark metallic in contrast to legs that are usually totally white to yellow (femora usually predominantly dark in European specimens, especially the hind femur), and having the scape almost entirely pale yellow to white (scape dark in European specimens, although occasionally pale basally). It is not clear whether this difference indicates that a distinct species is present, or merely represents intraspecific variation. At this point, it is being considered as within species variation for the following reasons. 1) Other than coloration, specimens agree well with European N. formosa, particularly in regards to sculpture on the thorax and gaster, nearly complete notauli, and an infumated spot on the wing posterior to the stigmal vein. 2) Coloration can be quite variable in Chalcidoidea. 3) Hansson (1990) has already pointed out the N. formosa is a highly variable species, and that among the characters that do display some variation are those of the colour of the femora and tibiae, and the colour of the scape. Further studies may prove that this is indeed a distinct species.

Non-commutativity and non-associativity of the doubled string in non-geometric backgrounds
Creators: name: Blair, Chris D. A.

Year: 2014
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We use a T-duality invariant action to investigate the behaviour of a string in non-geometric backgrounds, where there is a non-trivial global $O(D,D)$ patching or monodromy. This action leads to a set of Dirac brackets describing the dynamics of the doubled string, with these brackets determined only by the monodromy. This allows for a simple derivation of non-commutativity and non-associativity in backgrounds which are (even locally) non-geometric. We focus here on the example of the three-torus with H-flux, finding non-commutativity but not non-associativity, and also comment on the relation to the exotic $5^2_2$ brane, which shares the same monodromy.

Model-based clustering using copulas with applications

Publisher: name: arXiv
Year: 2014
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: The majority of model-based clustering techniques is based on multivariate Normal models and their variants. In this paper copulas are used for the construction of flexible families of models for clustering applications. The use of copulas in model-based clustering offers two direct advantages over current methods: i) the appropriate choice of copulas provides the ability to obtain a range of exotic shapes for the clusters, and ii) the explicit choice of marginal distributions for the clusters allows the modelling of multivariate data of various modes (either discrete or continuous) in a natural way. This paper introduces and studies the framework of copula-based finite mixture models for clustering applications. Estimation in the general case can be performed using standard EM, and, depending on the mode of the data, more efficient procedures are provided that can fully exploit the copula structure. The closure properties of the mixture models under marginalization are discussed, and for continuous, real-valued data parametric rotations in the sample space are introduced, with a parallel discussion on parameter identifiability depending on the choice of copulas for the components. The exposition of the methodology is accompanied and motivated by the analysis of real and artificial data.

description: We present new two-dimensional (2D) axisymmetric neutrino radiation/hydrodynamic models of core-collapse supernova (CCSN) cores. We use the CASTRO code, which incorporates truly multi-dimensional, multi-group, flux-limited diffusion (MGFLD) neutrino transport, including all relevant $\mathcal{O}(v/c)$ terms. Our main motivation for carrying out this study is to compare with recent 2D models produced by other groups who have obtained explosions for some progenitor stars and with recent 2D VULCAN results that did not incorporate $\mathcal{O}(v/c)$ terms. We follow the evolution of 12, 15, 20, and 25 solar-mass progenitors to approximately 600 milliseconds after bounce and do not obtain an explosion in any of these models. Though the reason for the qualitative disagreement among the groups engaged in CCSN modeling remains unclear, we speculate that the simplifying ``ray-by-ray' approach employed by all other groups may be compromising their results. We show that ``ray-by-ray' calculations greatly exaggerate the angular and temporal variations of the neutrino fluxes, which we argue are better captured by our multi-dimensional MGFLD approach. On the other hand, our 2D models also make approximations, making it difficult to draw definitive conclusions concerning the root of the differences between groups. We discuss some of the diagnostics often employed in the analyses of CCSN simulations and highlight the intimate relationship between the various explosion conditions that have been proposed. Finally, we explore the ingredients that may be missing in current calculations that may be important in reproducing the properties of the average CCSNe, should the delayed neutrino-heating mechanism be the correct mechanism of explosion.

description: Over last ten years Mobile & Marine Robotics Research Centre (MMRRC), University of Limerick, Ireland have developed OceanRINGS - a suite of smart technologies for subsea operations, designed to be integrated with any ROV – ship combination. It includes advanced control solutions for full range of ROVS – from mini ROVs used for remote monitoring & inspection to full-size work-class ROVs. Remotely Operated Vehicle (ROV) LATIS is a prototype platform developed at MMRRC to test and validate OceanRINGS. System validation and technology demonstration was performed over last five years through a series of test trials with different support vessels off the north, south and west coast of Ireland, in Donegal, Bantry Bay, Cork Harbour, Galway Bay, Shannon Estuary and La Spezia, Italy. The MMRRC team has developed Virtual Control Cabin concept, which provide a framework to control offshore robotic platforms from remote location in real time. Part of the overall system is demonstration platform to develop, test and validate control algorithms from remote locations using hardware-in-the?loop (HIL) real-time simulator running at UL lab. This paper provides more information about demonstration platform and discusses possible applications.

description: The displacement of micro-electro-mechanical-systems (MEMS) cantilevers is used to measure a broad variety of phenomena in devices ranging from force microscopes to biochemical sensors to thermal imaging systems. We demonstrate the first direct measurement of a MEMS cantilever displacement with a noise floor at 40% of the shot noise limit (SNL). By combining multi-spatial-mode quantum light sources with a simple differential measurement, we show that sub-SNL MEMS displacement sensitivity is highly accessible compared to previous efforts that measured the displacement of macroscopic mirrors with very distinct spatial structures crafted with multiple optical parametric amplifiers and locking loops. These results support a new class of quantum MEMS sensor with an ultimate signal to noise ratio determined by quantum correlations, enabling ultra-trace sensing, imaging, and microscopy applications in which signals were previously obscured by shot noise.

An Investigation of the Relationship between Organisational Culture and Sustainability Performance in Higher Education Institutions in Ilorin, Nigeria
Creators: name: Raimi, Bolaji
Publisher: name: Cardiff Metropolitan University

Subjects: Other commerce, management, tourism and services not elsewhere classified

description: Increasingly, higher education institutions (HEIs) around the world are embracing the responsibility of educating the next generation about sustainability principles. HEIs in developed nations are making great efforts by committing vast resources and recording outstanding success in this regard, but those in developing countries like Nigeria are not faring so well yet. The aim of this study is to investigate the role of organisational culture in influencingsustainability performance in three HEIs in Ilorin, Nigeria. The study uses a mixedmethod approach to investigate this relationship. A sample of 100 stakeholders is drawn from each institution and a structured questionnaire is used to collect stakeholders’ perceptions about organisational culture and sustainability performance. The relationship between organisational culture and sustainability performance is analysed through regression analysis. A content analysis is undertaken of both the vision and mission statements from each institution to explain the quantitative results. Findings from quantitative analysis show a positive relationship between organisational culture and sustainability performance in each institution. In contrast, findings of qualitative analysis do not reflect that sustainability practice is an organisational value of each institution. Further research to investigate the level of stakeholders’ understanding of best practice of sustainability is suggested in order to resolve the divergence in findings.The main contribution of the study is that it provides empirical knowledge about the relationship between organisational culture and sustainability performance in higher education. Moreover, it ascertains the right balance of organisational culture traits required to support sustainability performance.

description: We relate the observed hemispherical anisotropy in the cosmic microwave radiation data to an inhomogeneous power spectrum model. The hemispherical anisotropy can be parameterized in terms of the dipole modulation model. This model leads to correlations between spherical harmonic coefficients corresponding to multipoles, l and l+1. We extract the $l$ dependence of the dipole modulation amplitude, A, by making a fit to the WMAP and PLANCK CMBR data. We propose an inhomogeneous power spectrum model and show that it also leads to correlations between multipoles, l and l+1. The model parameters are determined by making a fit to the data. The spectral index of the inhomogeneous power spectrum is found to be consistent with zero.

Evaporation and Accretion of Extrasolar Comets Following White Dwarf Kicks

Year: 2014
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: Several lines of observational evidence suggest that white dwarfs receive small birth kicks due to anisotropic mass loss. If other stars possess extrasolar analogues to the Solar Oort cloud, the orbits of comets in such clouds will be scrambled by white dwarf natal kicks. Although most comets will be unbound, some will be placed on low angular momentum orbits vulnerable to sublimation or tidal disruption. The dusty debris from these comets will manifest itself as an IR excess temporarily visible around newborn white dwarfs; examples of such disks may already have been seen in the Helix Nebula, and around several other young white dwarfs. Future observations with the James Webb Space Telescope may distinguish this hypothesis from alternatives such as a dynamically excited Kuiper Belt analogue. Although competing hypotheses exist, the observation that $\gtrsim 15\%$ of young white dwarfs possess such disks, if interpreted as indeed being cometary in origin, provides indirect evidence that low mass gas giants (thought necessary to produce an Oort cloud) are common in the outer regions of extrasolar planetary systems. Hydrogen abundances in the atmospheres of older white dwarfs can, if sufficiently low, also be used to place constraints on the joint parameter space of natal kicks and exo-Oort cloud models.

Sequential Quantum Secret Sharing in a Noisy Environment aided with Weak Measurements

description: In this work we give a $(n,n)$-threshold protocol for sequential secret sharing of quantum information for the first time. By sequential secret sharing we refer to a situation where the dealer is not having all the secrets at the same time, at the beginning of the protocol; however if the dealer wishes to share secrets at subsequent phases she/he can realize it with the help of our protocol. First of all we present our protocol for three parties and later we generalize it for the situation where we have $(n>3)$ parties. Further in a much more realistic situation, we consider the sharing of qubits through two kinds of noisy channels, namely the phase damping channel (PDC) and the amplitude damping channel (ADC). When we carry out the sequential secret sharing in the presence of noise we observe that the fidelity of secret sharing at the $k^{th}$ iteration is independent of the effect of noise at the $(k-1)^{th}$ iteration. In case of ADC we have seen that the average fidelity of secret sharing drops down to $\frac{1}{2}$ which is equivalent to a random guess of the quantum secret. Interestingly, we find that by applying weak measurements one can enhance the average fidelity. This increase of the average fidelity can be achieved with certain trade off with the success probability of the weak measurements.

description: We study a fourth order geometric evolution problem on a network of curves in a bounded domain . The flow decreases a weighted total length of the curves and preserves the enclosed volumes. Stationary solutions of the flow are critical points of a partition problem in . In this paper we study the linearized stability of stationary solutions using the H−1-gradient flow structure of the problem. Important issues are the development of an appropriate PDE formulation of the geometric problem and Poincar´e type estimate on a network of curves.

description: After showing how to prove the integrated c-theorem within the functional RG framework based on the effective average action, we derive an exact RG flow equation for Zamolodchikov's c-function in two dimensions by relating it to the flow of the effective average action. In order to obtain a non-trivial flow for the c-function, we will need to understand the general form of the effective average action away from criticality, where nonlocal invariants, with beta functions as coefficients, must be included in the ansatz to be consistent. We then apply our construction to several examples: exact results, local potential approximation and loop expansion. In each case we construct the relative approximate c-function and find it to be consistent with Zamolodchikov's c-theorem. Finally, we present a relation between the c-function and the (matter induced) beta function of Newton's constant, allowing us to use heat kernel techniques to compute the RG running of the c-function.

description: We prove that any tame abstract elementary class categorical in a suitable cardinal has an eventually global good frame: a forking-like notion defined on all types of single elements. This gives the first known general construction of a good frame in ZFC. We show that we already obtain a well-behaved independence relation assuming only a superstability-like hypothesis instead of categoricity. These methods are applied to obtain an upward stability transfer theorem from categoricity and tameness, as well as new conditions for uniqueness of limit models.

description: In this paper the BTZ black hole geometry is probed with a noncommutative scalar field which obeys the $κ$-Minkowski algebra. The entropy of the BTZ black hole is calculated using the brick wall method. The contribution of the noncommutativity to the black hole entropy is explicitly evaluated up to the first order in the deformation parameter. We also argue that such a correction to the black hole entropy can be interpreted as arising from the renormalization of the Newton's constant due to the effects of the noncommutativity.

description: The melt-spun (MS) Ti50Ni25Cu25 alloy and the Zr62Cu22A110Fe5Dy1 bulk metallic glass (BMG) were subjected to high pressure torsion (HPT). X-ray diffraction (XRD) measurements show a shift of the first diffraction halo to a low angle after HPT processing, which corresponds to an increase in the values of the radius of the first coordination sphere and the free volume. Direct density measurements confirmed an increase in free volume values. A special TEM procedure was used for a detailed study of the microstructure of both amorphous alloys after HPT processing. The study revealed the formation of a large density of shear bands (SBs) in both alloys. Nanocrystals are formed directly in shear bands as a result of strain-inducted nanocrystallization. Amorphous nanoclusters with a size of 20 nm are formed in an amorphous matrix surrounding the SBs in the HPT-processed MS alloy Ti50Ni25Cu25. The formation of nanoclusters was not observed in BMG Zr62Cu22A110Fe5Dy1 after HPT processing.

description: We investigate mesons containing charm quarks on fine lattices with a^{-1} \sim 5 GeV. The quenched approximation is employed using the Wilson gauge action at \beta = 6.6 and nonperturbatively O(a) improved Wilson quarks. We present results for decay constants using various interpolating fields and give preliminary results for form factors of semileptonic decays of D_s mesons to light pseudoscalar mesons.

description: Green public procurement (GPP) has the potential to induce sustainable development and reduce the impact of the construction sector. However, there are obstacles to its effective implementation, mainly in developing countries. Herein, we proposed a GPP model and framework based on constructive systems’ environmental performance. We argue that the present proposal minimizes the gaps involving GPP and supports its implementation in the construction sector. The development of the GPP model and framework is based on an intensive theoretical overview, interview with stakeholders, and validation phase. Also, an integrated holistic framework for GPP adoption based on Life Cycle Assessment (LCA) and Environmental Product Declaration (EPD) is performed. Besides that, the GPP model is based on an integrated and collaborative system that involves all the stakeholders. This research contributes to the scarce GPP literature in the context of sustainability in developing countries and softens the lack of metrics to evaluate the environmental impacts of materials and buildings. The model has the potential to support the decision-making process in buildings’ early-stage design and integrates data and stakeholders promoting environmental awareness and can leverage the practice of GPP with appropriate comparisons. It opens a new perspective on the GPP providing knowledge and supporting decision-market.

description: We show that external control of Fano resonances in general leads to complex Fano $q$-parameters. Fano line shapes of photo-electron and transient absorption spectra in presence of an infrared control field are investigated. Computed transient absorption spectra are compatible with a recent experiment [C. Ott {\it et al.}, Science 340, 716 (2013)] but suggest a modification of the interpretation proposed there. Control mechanisms for photo-electron spectra are exposed: control pulses applied {\em during} excitation modify the line shapes by momentum boosts of the continuum electrons. Pulses arriving {\em after} excitation generate interference fringes due to infrared two-photon transitions.
title: Development of a boron-10 based Multi-Grid detector for neutron spectroscopy
Creators: name: Backis, Alexander
Publisher: name: University of Glasgow
Year: 2023

description: This work presents the continued development of the Multi-Grid, a boron-10-based cold to epithermal neutron detector technology. The Multi-Grid is a large area detector, tens of square meters, intended for time-of-flight neutron spectroscopy. The detector development started around 2010, and its first application is intended at the upcoming European Spallation Source, currently under construction in Lund, Sweden. This is to address the expected high flux at the upcoming facility, which is beyond the rate capabilities of current state-of-the-art detectors, and to substitute the large area helium-3 tube arrays commonly used for neutron spectroscopy, which have become prohibitively expensive at high He-3 gas pressures. Here, the latest developments are shown, based on measurements with the most recent implementations of the Multi-Grid, which are the MG.SEQ and MG.LET prototypes. This includes the characterisation of different detector properties – such as neutron detection efficiency, signal-to-background ratio and energy resolution – as well as an investigation on how to properly select an internal shielding design. It also includes a detailed account of the effects of internal neutron scattering and how it can be reduced. This is a general step-by-step guide on how to compare and evaluate different neutron shielding candidates and it is relevant for all neutron detectors, not just the Multi-Grid. The characterisation work is primarily based on data collected during two beamtimes: one at the ESS Test Beamline V20 at the Helmholtz-Zentrum Berlin, Germany, and one at the cold neutron spectrometer LET at the ISIS neutron and muon source, United Kingdom. For the internal shielding investigations, Geant4 was used together with the newly developed NCrystal library. Using these code packages, various shielding materials were modeled and simulations were performed of how neutrons interact with them. From the results, a signal-to-background ratio of approximately 10[sup]4 was shown together with an improvement in energy lineshape, which was broadly comparable to the LET helium-3 tubes and had a reduced energy smearing compared to that observed during a previous test at the CNCS instrument at the Spallation Neutron Source. Important information was obtained on how the effects on internal neutron scattering can be attenuated, and a direct comparison was made with state-of-the-art helium-3 detectors in the LET instrument. The energy resolution was also studied in detail and the detection efficiency was re-confirmed. These contributions bring the development of the detector towards its finalisation and use at neutron scattering facilities.
