description: CP-violating effects in non-leptonic $B_s$-meson decays are reviewed. Special emphasis is given to implications arising from the width difference $ΔΓ_s$ between the $B_s$ mass eigenstates. If $ΔΓ_s$ is found to be sizable, certain untagged $B_s$-meson decays may allow interesting probes of CP violation, extractions of the CKM angle $γ$ and the Wolfenstein parameter $η$, and may indicate physics beyond the Standard Model.

Assessment of the Onshore Environmental Impact of Offshore Wind Farms: A Case Study of Triton Knoll, Lincolnshire
Creators: name: Wathek, Zair
Publisher: name: Zenodo
Year: 2010
Subjects: subject: Wind farms, Environmental Impact
subject: http://id.loc.gov/authorities/subjects/sh00007934

description: In current times, wind farms are dramatically expanding in the UK. In many regions, people express strong opposition to the operation and installation of wind turbines. This dissertation investigates and evaluates the onshore environmental impact of offshore wind farms with the intention of providing a deeper insight into the reasons underpinning the concerns of local residents regarding this development.
 The focus of this research is limited to the Triton Knoll wind farm site in Lincolnshire. Questionnaire responses strongly suggest that renewable energy, including the exploitation of wind power is well regarded amongst local residents. Nevertheless, the proposed substation site is currently the subject of intense scrutiny and forceful opposition, particularly in relation to its potential environmental impact.
 Data on noise, land protection status and other related factors indicates that the location is a suitable area and that noise should not be of concern to the residents. However, analysis of maps and interview data indicates that it is likely that there will be a considerable effect upon landscape substances and visual receivers. Moreover, the development will potentially have a considerable impact upon nature and ecological conservation.

We have also determined spin-wave stiffness constants and found the dispersion curves for metals in question employing the Fourier transform of calculated Heisenberg exchange parameters. Curie temperatures were calculated both in the mean-field approximation and within the Green function random phase approximation. The latter results were found to be in a better agreement with available experimental data.

Quantifying the incompatibility of quantum measurements relative to a basis

Publisher: name: arXiv
Year: 2019
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Motivated by quantum resource theories, we introduce a notion of incompatibility for quantum measurements relative to a reference basis. The notion arises by considering states diagonal in that basis and investigating whether probability distributions associated with different quantum measurements can be converted into one another by probabilistic post-processing. The induced preorder over quantum measurements is directly related to multivariate majorization and gives rise to families of monotones, i.e., scalar quantifiers that preserve the ordering. For the case of orthogonal measurement we establish a quantitative connection between incompatibility, quantum coherence and entropic uncertainty relations. We generalize the construction to arbitrary POVM measurements and report complete families of monotones.
description: Construction generalized to include POVMs. A modified preorder, related to post-processing by stochastic matrices, is also included. New result on coherence. Improved exposition

description: This paper employs the concepts of gender norms and agency to advance understanding of inclusive agricultural innovation processes and their contributions to empowerment and poverty reduction at the village level. We present a community typology informed by normative influences on how people assess conditions and trends for village women and men to make important decisions (or to exercise agency) and for local households to escape poverty. The typology is comprised of three village typestransforming, climbing and churning with each type depicting a different normative climate and trajectory of change in agency and poverty levels. Across “transforming” villages with significant increases in people’s agency and poverty reduction, we found a highly inclusive normative climate that is fueling gender equality and agricultural innovation, as well as infrastructural improvements, expanded markets, and male labor migration. The research, part of the GENNOVATE initiative, includes a qualitative comparative methodology and dataset of 79 village cases from 17 countries.

Theory of Pseudogap Phenomena in High-Tc Cuprates Based on the Strong Coupling Superconductivity

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: In this paper we study the effects of the strong coupling superconductivity on the normal state electronic structure. We point out that the pseudogap phenomena in High-T_c cuprates are naturally explained as a precursor of the strong coupling superconductivity. We expand the reciprocal of the T-matrix with respect to the momentum and the frequency, and we discuss the properties of the expansion parameters. We estimate these parameters and carry out the calculations for the single particle self-energy using the T-matrix and the self-consistent T-matrix approximations, respectively. We show that the superconducting fluctuations, which are strongly diffusive within the conventional weak coupling theory, become propagative and have the character of the pre-formed pairs in the strong coupling case. The spectral weight and the density of states show the gap-like features by the effects of the resonances with the thermally excited weakly-damped pre-formed pairs. The spectral weight at the Fermi energy is strongly suppressed. This suppression starts at the mean field critical temperature $T_{MF}$ and the actual critical temperature T_c is strongly reduced owing to the fluctuations. These features properly explain to the pseudogap phenomena in High-T_c cuprates.

The results are consistent with standard model expectations, with the possible exception of one event that has in addition to the two photons a central electron, a high-E_T electromagnetic cluster, and large $\mett$. We set limits using two specific SUSY scenarios for production of diphoton events with $\mett$.

description: A lepton flavor violating process $μ\to eγ$ is investigated in the supersymmetric extra U(1) models, which often appear as the low energy effective models of superstring and can potentially solve the $μ$-problem. The branching ratio of this process is calculated. It is numerically estimated and compared with that of the MSSM. In this study we take account of an abelian gaugino kinetic term mixing and discuss its influence on this process. The possibility to find the extra gauge structure through this process is discussed.

Information Literacy: Graduate Attributes for Employability: Are we Talking the Same Language?
Creators: name: Robertson, Lynne
Publisher: name: Reflective Professional
Year: 2021

description: This study portrays an interconnectedness between graduate attributes and information literacy skills and attributes preparing students for future careers. Research in the area of workplace information literacy has demonstrated the effectiveness of information literacy as a transitional skill from academia into the working place. However, there is currently an information literacy skills deficit in graduates coming from different disciplines. With Higher Education Institutions (HEI) placing emphasis on graduate attributes for employability, there are opportunities for academic librarians to explore information literacy as a graduate skill and assert information literacy instruction as more than a one-off workshop and as a practice embedded into the curriculum. This research has relevance to academic librarians and curriculum programme developers. This research has focused on six main information literacy themes: Discover and Access; Interpret, Analyse; Manage and Store; Create with Information; Communicate with Information and Collaboration. The last three themes consider ethical practice within the domain of graduate attributes. Template analysis was conducted on fourteen Scottish Universities’ graduate attributes public pages and across four graduate Scottish recruitment websites to review thirty-seven graduate job vacancies over a set time period. Using social constructivism theory, information literacy skills found in job advertisements were analysed with the purpose of mapping academic librarian terminology against industry terminology. The findings conclude an inconsistency in terminology between academia and industry terminology as collated through the above methods. This calls for relevant stakeholders to engage in an audit of meaningful skills to inform a core shared language, and a holistic organisational approach to delivering information literacy through an interdisciplinary approach. In response to this finding and wider debates within academia, the study offers practical advice to academic librarians as a catalyst for change. This is offered through identifying overlapping and interconnected terms, which an academic librarian can apply to classroom narratives and therefore move closer to teaching students how to have a clearer understanding of what potential employers are seeking and allow them to have a language to articulate this with meaning. Overall, the findings suggest that discipline knowledge alone is not enough to prepare new graduates to be work-ready.

A comparative study of collection development practices in English Literature across a sample of UK academic libraries
Creators: name: McCombie, Arleen
Publisher: name: Reflective Professional
Year: 2021

description: The development of academic library collections and the guarantee of their quality and coherence have for decades depended on the knowledge of the subject specialist. Yet with the advent of information technology the importance of subject domain knowledge and disciplinary structures within the library has been challenged. The research issue investigated here has been stimulated by the paucity of studies on collection development as applied to a single academic discipline, English Literature. This study seeks to explore how collection decisions are made and what contextual factors influence the thinking of academic librarians. Therefore rather than simply gathering facts the focus of this study is on individual perspectives. Furthermore, it takes a deliberately holistic approach by examining collection development in the round instead of looking at a particular component. The key findings of this study are that traditional collection development continues to be a critical responsibility of academic liaison librarians, but that a more collaborative approach to collection development is being instituted in practice. In particular, the knowledge of the academic librarian is being partly diluted through new organisational structures and purchasing methods. At least for the near future, however, academic librarians continue to be confident about their own relevance and contribution to the collection development process.

On Neutron Star Mergers as the Source of r-process Enhanced Metal Poor Stars in the Milky Way

description: We model the history of Galactic r-process enrichment using high-redshift, high-resolution zoom cosmological simulations of a Milky Way (MW) type halo. We assume that all r-process sources are neutron star mergers (NSMs) with a power law delay time distribution. We model the time to mix pollutants at subgrid scales, which allows us to to better compute the properties of metal poor (MP) and carbon enhanced metal poor (CEMP) stars, along with statistics of their r-process enhanced subclasses. Our simulations underpredict the cumulative ratios of r-process enhanced MP and CEMP stars (MP-r, CEMP-r) over MP and CEMP stars by about one order of magnitude, even when the minimum coalescence time of the double neutron stars ($t_{\rm min}$) is set to 1 Myr. No r-process enhanced stars form if $t_{\rm min}=100$ Myr. Our results show that even when we adopt the r-process yield estimates observed in GW170817, NSMs by themselves can only explain the observed frequency of r-process enhanced stars if either the birth rate of double neutron stars per unit mass of stars is boosted to $\approx10^{-4} M_\odot^{-1}$ or the Europium yield of each NSM event is boosted to $\approx 10^{-4} M_{\odot}$.

Based on a renormalization group calculation, we derive detailed results for the degrees of translational and orientational order of the stripe pattern at zero temperature and carefully map out the disorder and length-scale regimes in which the system effectively exhibits smectic, nematic, or isotropic behavior. We show that disorder always leads to a finite density of free dislocations and estimate the scale on which they begin to appear.

Glauber dynamics in a zero magnetic field and eigenvalue spacing statistics
Creators: name: Mélin, R.
Publisher: name: arXiv
Year: 1996
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: We discuss the eigenvalue spacing statistics of the Glauber matrix for various models of statistical mechanics (a one dimensional Ising model, a two dimensional Ising model, a one dimensional model with a disordered ground state, and a SK model with and without a ferromagnetic bias). The dynamics of the one dimensional Ising model are integrable, and the eigenvalue spacing statistics are non-universal. In the other cases, the eigenvalue statistics in the high temperature regime are intermediate between Poisson and G.O.E (with $P(0)$ of the order of $0.5$). In the intermediate temperature regime, the statistics are G.O.E.. In the low temperature regime, the statistics have a peak at $s=0$. In the low temperature regime, and for disordered systems, the eigenvalues condense around integers, due to the fact that the local field on any spin never vanishes. This property is still valid for the Ising model on the Cayley tree, even if it is not disordered. We also study the spacing between the two largest eigenvalues as a function of temperature. This quantity seems to be sensitive to the existence of a broken symmetry phase.

description: There is a high demand for hardwood timber, such as hybrid walnut, in the EU. To meet this demand, over the last decade, hardwood plantations have substantially increased production in many Spanish regions. Intensive management is often required to grow these trees in short rotations. Such management comprises irrigation, fertilisation, and chemical weed control. However, this level of management has high economic and environmental costs. Plantation management accounts for more than 45% of the total investment costs. Moreover, these operations can have major environmental impacts, similar to the effects of intensive agriculture systems. Introducing livestock and sowing legumes can reduce the financial costs of these plantations and optimize their environmental functions. This is known as a silvopastoral system.

description: The present work reports a general method for the calculation of t he polarizability of a truncated sphere on a substrate. A multipole ex pansion is used, where the multipoles are not necessarily localized in the center of the sphere but can freely move on the revolution axis. From the weak formulation of the boundary conditions, an infinite set of linear equations for the multipole coefficients is derived. To obta in this set, the interaction between the island and the substrate is t aken into account by the technique of image multipoles. For numerical implementation, this set is truncated at an arbitrary mu ltipole order. The accuracy of the method is jugded through the stabil ity of the truncated sphere polarizability and the the fulfilment of t he boundary conditions which are demonstrated to be satisfied in large regions of the parameter space. This method brings an improvement wit h respect to the Bedeaux's case \cite{Wind87a,Wind87b} where the multi poles are located in the center of the sphere.

A limit of 43.2 MeV at 95% CL is obtained using a two-dimensional method in the 5pi invariant mass and energy distribution from 22 selected events. Combining this result with OPAL's previously published measurement using tau+tau- -> 3h+- \bar{nu}_tau 3h-+ ν_tau decays, a new combined limit of m_{nu_tau} < 27.6 MeV (95% CL) is obtained.

It is calculated for $\bf k$ on the Fermi surface, and ${\bf Q}=(\pm {π\over a}, \pm {π\over a})$. We find that the dimensionless ratio $|δΛ_{\bf k}|/Λ_\circ$, which parametrizes the vertex correction, is not small. It is a maximum for ${\bf k=k_h}$, where ${\bf k_h}$ is a ``hot spot'' on the Fermi surface. This makes large quantitative corrections to the theory.

An investigation into secondary school teachers’ understanding, perception and practice of information literacy and continuous professional development
Creators: name: Lamont, Emma-Louise
Publisher: name: Reflective Professional
Year: 2021

description: The aim of this research was to gain an insight into how Scottish secondary teachers’ conduct their CPD and to explore their understanding of and engagement with information literacy, and whether they continue to develop their information literacy through their CPD. To consider if teachers have the need for further support in developing their information literacy and whether they have cultivated skills in information literacy through prior experiences in education and work. A qualitative methods approach was selected as being most viable for collecting data which deals with perspectives and complex ideas. Using semi-constructed interviews, it allowed teachers to share their individual experiences and stories. Vignettes were also used, to allow teachers to provide their own understanding of information literacy and to demonstrate components of information literacy which they would teach. The term information literacy was not expected to be a term familiar to teachers, as prior research had already discovered, so the use of vignettes provided better insight without having to rely on using terminology which may cause confusion for participants. To provide a context to teachers’ understanding of information literacy, a textual analysis was carried out on the Scottish curriculum. The results of the interviews, responses to the vignettes and textual analysis result were analysed and discussed in the context of the literature review. The investigation found that although teachers were unfamiliar with information literacy, they understood the fundamental skills associated with it and recognised its significance for education and for general life skills. They were confident in their own information literacy abilities but considered there to be no professional development support available to them. They also did not recognise some of their informal CPD practices to develop their information literacy.

description: Phase-ordering dynamics in nematic liquid crystals has been the subject of much active investigation in recent years in theory, experiments and simulations. With a rapid quench from the isotropic to nematic phase a large number of topological defects are formed and dominate the subsequent equilibration process. We present here the results of a molecular dynamics simulation of the Gay-Berne model of liquid crystals after such a quench in a system with 65536 molecules. Twist disclination lines as well as type-1 lines and monopoles were observed. Evidence of dynamical scaling was found in the behavior of the spatial correlation function and the density of disclination lines. However, the behavior of the structure factor provides a more sensitive measure of scaling, and we observed a crossover from a defect dominated regime at small values of the wavevector to a thermal fluctuation dominated regime at large wavevector.

description: We consider the interplay of a quark state and a hadronic threshold in the framework of the P-matrix formalism, which is reviewed and extended for use together with conventional methods of computing quark-gluon dynamics. We provide a quantitative dynamical interpretation of the reduced R or K matrices and their poles that suggests a natural classification of threshold phenomena. At a threshold with a quark state close to it up to three S-matrix poles can be found. The scattering amplitudes for the corresponding cases are discussed. Our analysis is applied to make an outlook for experimental observation of the doubly strange H-dibaryon if it is not stable to strong decays.

Transport and Coulomb drag for two interacting carbon nanotubes

description: We study nonlinear transport for two coupled one-dimensional quantum wires or carbon nanotubes described by Luttinger liquid theory. Transport properties are shown to crucially depend on the contact length $L_c$. For a special interaction strength, the problem can be solved analytically for arbitrary $L_c$. For point-like contacts and strong interactions, a qualitatively different picture compared to a Fermi liquid emerges, characterized by zero-bias anomalies and strong dependence on the applied cross voltage. In addition, pronounced Coulomb drag phenomena are important for extended contacts.

Bouligand-Levenberg-Marquardt iteration for a non-smooth ill-posed inverse problem

description: In this paper, we consider a modified Levenberg--Marquardt method for solving an ill-posed inverse problem where the forward mapping is not Gâteaux differentiable. By relaxing the standard assumptions for the classical smooth setting, we derive asymptotic stability estimates that are then used to prove the convergence of the proposed method. This method can be applied to an inverse source problem for a non-smooth semilinear elliptic PDE where a Bouligand subdifferential can be used in place of the non-existing Fréchet derivative, and we show that the corresponding Bouligand-Levenberg-Marquardt iteration is an iterative regularization scheme. Numerical examples illustrate the advantage over the corresponding Bouligand-Landweber iteration.

description: Instant machine learning predictions of molecular properties are desirable for materials design, but the predictive power of the methodology is mainly tested on well-known benchmark datasets. Here, we investigate the performance of machine learning with kernel ridge regression (KRR) for the prediction of molecular orbital energies on three large datasets: the standard QM9 small organic molecules set, amino acid and dipeptide conformers, and organic crystal-forming molecules extracted from the Cambridge Structural Database. We focus on prediction of highest occupied molecular orbital (HOMO) energies, computed at density-functional level of theory. Two different representations that encode molecular structure are compared: the Coulomb matrix (CM) and the many-body tensor representation (MBTR). We find that KRR performance depends significantly on the chemistry of the underlying dataset and that the MBTR is superior to the CM, predicting HOMO energies with a mean absolute error as low as 0.09 eV. To demonstrate the power of our machine learning method, we apply our model to structures of 10k previously unseen molecules. We gain instant energy predictions that allow us to identify interesting molecules for future applications.

description: We performed an optical spectroscopy study of electronic and magnetic excitations for a rare-earth system with a single electron quasi-localized in the f-shell on an ion at high-symmetry crystallographic site in application to CeB$_{6}$ heavy-fermion metal. We carried out group-theoretical classification of the electronic crystal field (CF) transitions and assessed their coupling to light cross-sections for polarization resolved Raman scattering processes. We discuss applicability of symmetrized Raman susceptibility to studies of exotic charge and spin high multiplet ordering phases in f-electron systems. We study temperature effects on intra- and inter-multiplet CF transitions and also on the coupling between the CF excitations with the lattice vibrations. We acquired temperature dependence of the low-frequency polarization resolved Raman response and obtained the static Raman susceptibility for all Raman-allowed symmetry channels: A$_{1g}$, E$_{g}$, T$_{1g}$, and T$_{2g}$ of the cubic O$_{h}$ point group. We demonstrate that for CeB$_{6}$ system only T$_{1g}$-symmetry static Raman susceptibility shows an anomalous temperature dependence which is consistent with the magnetic susceptibility data measured by other techniques. This anomalous behavior in the T$_{1g}$-channel signifies the presence of long wavelength magnetic fluctuations, while the lack of susceptibility enhancement for all the remaining symmetry channels indicates that long wavelength charge quadrupole fluctuations at low-temperature are weak.
Bose-Einstein Correlations of Three Charged Pions in Hadronic Z^0 Decays

description: Bose-Einstein Correlations (BEC) of three identical charged pions were studied in 4 x 10^6 hadronic Z^0 decays recorded with the OPAL detector at LEP. The genuine three-pion correlations, corrected for the Coulomb effect, were separated from the known two-pion correlations by a new subtraction procedure. A significant genuine three-pion BEC enhancement near threshold was observed having an emitter source radius of r_3 = 0.580 +/- 0.004 (stat.) +/- 0.029 (syst.) fm and a strength of λ_3 = 0.504 +/- 0.010 (stat.) +/- 0.041 (syst.). The Coulomb correction was found to increase the λ_3 value by \~9% and to reduce r_3 by ~6%. The measured λ_3 corresponds to a value of 0.707 +/- 0.014 (stat.) +/- 0.078 (syst.) when one takes into account the three-pion sample purity. A relation between the two-pion and the three-pion source parameters is discussed.

description: We consider the electronic transport in bounded semiconductors in the presence of an external magnetic field. Taking into account appropriate boundary conditions for the current density at the contacts, a change in the magnetoresistance of bulk semiconductors is found as compared with the usual theory of galvanomagnetic effects in boundless media. New mechanism in magnetoresistance connected with the boundary conditions arises. In particular, even when the relaxation time is independent of the electron energy, magnetoresistance is not vanish.

description: Strongly squeezed states of light are a key technology in boosting the sensitivity of interferometric setups, such as in gravitational-wave detectors. However, the practical use of squeezed states is limited by optical loss, which reduces the observable squeeze factor. Here we experimentally demonstrate that introducing squeezed states in additional, higher-order spatial modes can significantly improve the observed nonclassical sensitivity improvement when the loss is due to mode-matching deficiencies. Our results could be directly applied to gravitational-wave detectors, where this type of loss is a major contribution.
