description: Electrons on liquid helium can form different phases depending on density, and temperature. Also the electron-ripplon coupling strength influences the phase diagram, through the formation of so-called "ripplonic polarons", that change how electrons are localized, and that shifts the transition between the Wigner solid and the liquid phase. We use an all-coupling, finite-temperature variational method to study the formation of a ripplopolaron Wigner solid on a liquid helium film for different regimes of the electron-ripplon coupling strength. In addition to the three known phases of the ripplopolaron system (electron Wigner solid, polaron Wigner solid, and electron fluid), we define and identify a fourth distinct phase, the ripplopolaron liquid. We analyse the transitions between these four phases and calculate the corresponding phase diagrams. This reveals a reentrant melting of the electron solid as a function of temperature. The calculated regions of existence of the Wigner solid are in agreement with recent experimental data.

description: The proliferation of Internet-enabled devices and services has led to a shifting balance between digital and analogue aspects of our everyday lives. In the face of this development there is a growing demand for the study of privacy hazards, the potential for unique user de-anonymization and information leakage between the various social media profiles many of us maintain. To enable the structured study of such adversarial effects, this paper presents a dedicated dataset of cross-platform social network personas (i.e., the same person has accounts on multiple platforms). The corpus comprises 850 users who generate predominantly English content. Each user object contains the online footprint of the same person in three distinct social networks: Twitter, Instagram and Foursquare. In total, it encompasses over 2.5M tweets, 340k check-ins and 42k Instagram posts. We describe the collection methodology, characteristics of the dataset, and how to obtain it. Finally, we discuss a common use case, cross-platform user identification.

description: We investigate the large-scale transport of inertial particles. We derive explicit analytic expressions for the eddy diffusivities for generic Stokes times. These latter expressions are exact for any shear flow while they correspond to the leading contribution either in the deviation from the shear flow geometry or in the Péclet number of general random Gaussian velocity fields. Our explicit expressions allow us to investigate the role of inertia for such a class of flows and to make exact links with the analogous transport problem for tracer particles.

description: Random number generators are essential to ensure performance in information technologies, including cryptography, stochastic simulations and massive data processing. The quality of random numbers ultimately determines the security and privacy that can be achieved, while the speed at which they can be generated poses limits to the utilisation of the available resources. In this work we propose and demonstrate a quantum entropy source for random number generation on an indium phosphide photonic integrated circuit made possible by a new design using two-laser interference and heterodyne detection. The resulting device offers high-speed operation with unprecedented security guarantees and reduced form factor. It is also compatible with complementary metal-oxide semiconductor technology, opening the path to its integration in computation and communication electronic cards, which is particularly relevant for the intensive migration of information processing and storage tasks from local premises to cloud data centres.

description: The purpose of this thesis was to explore how music therapists can engage in cultural humility and leverage cultural assets of those who are culturally and linguistically diverse (CLD). The primary research question involved in this study was: “In what ways can music therapists leverage cultural assets of CLD individuals in practice?” Sub-questions were: “What awareness, knowledge, and skills do music therapists need to grow in culturally sensitive practice?” “How can music therapists whose first language is English effectively serve linguistically diverse individuals?” “What steps might music therapists take to effectively serve culturally diverse individuals?” and “How might cultural and linguistic diversity influence the therapeutic relationship?” I investigated these questions using a qualitative phenomenological study. Specifically, I conducted semi-structured interviews with a purposive sample of eight experts including music therapists, specialists in Universal Design for Learning (UDL), and specialists in diversity, equity, and inclusion. I analyzed and interpreted the findings from these interviews using a combined inductive and deductive qualitative data analysis approach. Throughout this study, I used the frameworks of UDL and the Multicultural and Social Justice Counseling Competencies to inform research and interview questions, analysis, and interpretation of results. Findings of this study provide foundation and practical guidance for music therapists regarding inclusive, equitable, and culturally sensitive clinical practices with CLD individuals.

description: Decycling and dismantling of complex networks are underlying many important applications in network science. Recently these two closely related problems were tackled by several heuristic algorithms, simple and considerably sub-optimal, on the one hand, and time-consuming message-passing ones that evaluate single-node marginal probabilities, on the other hand. In this paper we propose a simple and extremely fast algorithm, CoreHD, which recursively removes nodes of the highest degree from the $2$-core of the network. CoreHD performs much better than all existing simple algorithms. When applied on real-world networks, it achieves equally good solutions as those obtained by the state-of-art iterative message-passing algorithms at greatly reduced computational cost, suggesting that CoreHD should be the algorithm of choice for many practical purposes.

description: We numerically study an analogue black hole with two horizons with similar parameters to a recent experiment. We find that the Hawking radiation exists on a background which contains a density oscillation, a zero-frequency ripple. The Hawking radiation evolves from spontaneous to self-amplifying, while the background ripple grows steadily with no qualitative change. It is seen that the self-amplifying Hawking radiation has a non-zero frequency. The background ripple appears even before the inner horizon is created, in contrast to predictions. This work is in agreement with the recent observation of self-amplifying Hawking radiation, and explains some of the features seen. In contrast to recent works, our study differentiates between the Hawking radiation observed, and the evolution of the background.

title: A study of the arom enzyme complex by limited proteolysis
Creators: name: Smith, David Drummond Stewart
Publisher: name: University of Glasgow
Year: 1980
Subjects: subject: Biochemistry.

description: An improved method of purifying the arom complex from N. crassa has been devised. This procedure takes advantage of the tight binding of the arom complex to blue-dextran sepharose and yields around 3mg of pure enzyme from 100g of lyophilised N. crassa mycelia (30-35%). Limited proteolysis has been used to probe the domain structure of the arom complex. The shikimate kinase activity of the complex is very susceptible to inactivation by proteolysis and is probably located on the surface of the arom complex. A 69000 molecular weight domain containing both the shikimate dehydrogenase and dehydroquinase activities of the arom complex has been characterised by a combination of gel electrophoresis in the presence of IM urea, 8M urea and SDS and by substrate-labelling of the dehydroqmnase active-site. The shikimate dehydrogenase-dehydroquinase proteolytic fragment of the arom complex can regain shikimate dehydrogenase activity after polyacrylamide gel electrophoresis in the presence of 8M urea. This domain of the arom complex can refold in the absence of the remainder of the arom polypeptide. Under the same conditions shikimate dehydrogenase activity was not regained from the arom complex after polyacrylamide gel electrophoresis in the presence of 8M urea. Evidence has been obtained that a proteolytic fragment of molecular weight 110000 is produced from the N-terminal region of the arom polypeptide and may catalyse both the dehydroqmnate synthetase and EPSP synthetase reactions of the complex. Chemical modification of the arom complex with formaldehyde/ sodium borohydride inactivated both the shikimate dehydrogenase and dehydroquinase activities of the complex. Shikimate protected the shikimate dehydrogenase but not the dehydroquinase activity against inactivation by reductive alkylation. This and other evidence indicated that the shikimate dehydrogenase and dehydroquinase active-sites are spatially distinct.

description: We report the detection of a very low mass star (VLMS) companion to the primary star 1SWASPJ234318.41+295556.5A (J2343+29A), using radial velocity (RV) measurements from the PARAS (PRL Advanced Radial-velocity Abu-sky Search) high resolution echelle spectrograph. The periodicity of the single-lined eclipsing binary (SB1) system, as determined from 20 sets of RV observations from PARAS and 6 supporting sets of observations from SOPHIE data, is found to be 16.953 d as against the 4.24 d period reported from SuperWasp photometry. It is likely that inadequate phase coverage of the transit with SuperWasp photometry led to the incorrect determination of the period for this system. We derive the spectral properties of the primary star from the observed stellar spectra: Teff = 5125 +/- 67 K, [Fe/H] = 0.1 +/- 0.14 and log g = 4.6 +/- 0.14, indicating a K1V primary. Applying the Torres relation to the derived stellar parameters, we estimate a primary mass 0.864 +/- 0.097 M_sun and a radius of 0.854 +/- 0.050 R_sun. We combine RV data with SuperWASP photometry to estimate the mass of the secondary, M_B = 0.098 +/- 0.007 M_sun, and its radius, R_B = 0.127 +/- 0.007 R_sun, with an accuracy of around 7%. Although the observed radius is found to be consistent with the Baraffe's theoretical models, the uncertainties on the mass and radius of the secondary reported here are model dependent and should be used with discretion. Here, we establish this system as a potential benchmark for the study of VLMS objects, worthy of both photometric follow-up and the investment of time on high-resolution spectrographs paired with large-aperture telescopes.

On the channel width-dependence of the thermal conductivity in ultra-narrow graphene nanoribbons

description: The thermal conductivity of low-dimensional materials and graphene nanoribbons in particular, is limited by the strength of line-edge-roughness scattering. One way to characterize the roughness strength is the dependency of the thermal conductivity on the channel width in the form W^β. Although in the case of electronic transport this dependency is very well studied, resulting in W^6 for nanowires and quantum wells and W^4 for nanoribbons, in the case of phonon transport it is not yet clear what this dependence is. In this work, using lattice dynamics and Non-Equilibrium Greens Function simulations, we examine the width dependence of the thermal conductivity of ultra-narrow graphene nanoribbons under the influence of line edge-roughness. We show that the exponent β is in fact not a single well-defined number, but it is different for different parts of the phonon spectrum depending on whether phonon transport is ballistic, diffusive, or localized. The exponent β takes values β < 1 for semi-ballistic phonon transport, values β >> than 1 for sub-diffusive or localized phonons, and β = 1 only in the case where the transport is diffusive. The overall W^β dependence of the thermal conductivity is determined by the width-dependence of the dominant phonon modes (usually the acoustic ones). We show that due to the long phonon mean-free-paths, the width-dependence of thermal conductivity becomes a channel length dependent property, because the channel length determines whether transport is ballistic, diffusive, or localized.

description: Dietary calcium intake is a modifiable, lifestyle factor that can affect bone health and the risk of fracture. The diurnal rhythm of bone remodelling suggests nocturnal dietary intervention to be most effective. This study investigated the effect of daily, bed-time ingestion of a calcium-fortified, milk-derived protein matrix (MBPM) or control (CON), for 24 weeks, on serum biomarkers of bone resorption (C-terminal telopeptide of type I collagen, CTX) and formation (serum pro-collagen type 1 N-terminal propeptide, P1NP), and site-specific aerial bone mineral density (BMD), trabecular bone score (TBS), in postmenopausal women with osteopenia. The MBPM supplement increased mean daily energy, protein, and calcium intake, by 11, 30, and 107%, respectively. 24-week supplementation with MBPM decreased CTX by 23%, from 0.547 (0.107) to 0.416 (0.087) ng/mL (p < 0.001) and P1NP by 17%, from 60.6 (9.1) to 49.7 (7.2) µg/L (p < 0.001). Compared to CON, MBPM induced a significantly greater reduction in serum CTX (mean (CI95%); −9 (8.6) vs. −23 (8.5)%, p = 0.025 but not P1NP −19 (8.8) vs. −17 (5.2)%, p = 0.802). No significant change in TBS, AP spine or dual femur aerial BMD was observed for CON or MBPM. This study demonstrates the potential benefit of bed-time ingestion of a calcium-fortified, milk-based protein matrix on homeostatic bone remodelling but no resultant treatment effect on site-specific BMD in postmenopausal women with osteopenia.

description: Nanophotonic interfaces between single emitters and light promise to enable new quantum optical technologies. Here, we use a combination of finite element simulations and analytic quantum theory to investigate the interaction of various quantum emitters with slot-waveguide rings. We predict that for rings with radii as small as 1.44 $μ$m (Q = 27,900), near-unity emitter-waveguide coupling efficiencies and emission enhancements on the order of 1300 can be achieved. By tuning the ring geometry or introducing losses, we show that realistic emitter-ring systems can be made to be either weakly or strongly coupled, so that we can observe Rabi oscillations in the decay dynamics even for micron-sized rings. Moreover, we demonstrate that slot waveguide rings can be used to directionally couple emission, again with near-unity efficiency. Our results pave the way for integrated solid-state quantum circuits involving various emitters.

description: In this paper we propose a new stable and accurate approximation technique which is extremely effective for interpolating large scattered data sets. The Partition of Unity (PU) method is performed considering Radial Basis Functions (RBFs) as local approximants and using locally supported weights. In particular, the approach consists in computing, for each PU subdomain, a stable basis. Such technique, taking advantage of the local scheme, leads to a significant benefit in terms of stability, especially for flat kernels. Furthermore, an optimized searching procedure is applied to build the local stable bases, thus rendering the method more efficient.

description: How do non-governmental organizations (NGOs) target governments for climate shaming? NGOs increasingly function as monitors of states climate performance and compliance with international climate treaties such as the Paris Agreement. Lacking formal sanctioning capacities, NGOs primarily rely on ‘naming and shaming’ to hold states accountable to their commitments in climate treaties and to ramp up their climate mitigation efforts. However, we know little about how and why NGOs engage in climate shaming. This article advances two arguments. First, we argue that NGO climate shaming is likely to be shaped by the international and national climate records of governments. Second, governments’ climate actions can create contradicting expectations by both inviting and repelling NGO climate shaming. To test our arguments, we complied an original global data set on climate shaming events carried out by environmental NGOs. Our empirical analysis suggests that while NGOs are generally more likely to shame climate laggards, climate frontrunners may also be shamed if they engage in non-binding climate commitments. Climate laws and international climate treaties are central for our understanding of how NGOs target governments for climate shaming.NGOs are generally more likely to target climate laggards than frontrunners.Climate shaming is not only about whether but also how governments participate in global climate governance.Membership in climate institutions with non-binding commitments attracts NGO climate shaming.There is a risk that governments sign international climate treaties, without the intention to comply, in order to escape climate shaming.

description: Personal carbon allowances (PCAs) can complement current carbon pricing policies to achieve the sharp cut in emissions needed to meet the climate targets set by the Paris Agreement. While their effectiveness crucially depends on their social acceptability, there is little evidence on which specific characteristics of their design are preferred by citizens and how these preferences might differ within a society. Our study aims at eliciting preferences for a specific PCA scheme and explores their heterogeneity, using a discrete choice experiment among Belgian citizens and analyzing mixed logit and latent class models. Discrete choice experiments are a widely used tool to deliver key insights to policy design, but have rarely been used in the context of a PCA design. We find that intergenerational differences are important factors to explain citizens’ willingness to accept a PCA, with younger people strongly in favour. A PCA that includes carbon price regulations and provides tailor-made advice on how to reduce carbon emissions, is more likely to be accepted. However, purchase limits for emission thresholds beyond which a tax is imposed should be carefully introduced, as we find large heterogeneity across citizens’ willingness to accept this. These differences are correlated with current emission and income levels, and awareness about PCA. Our study is a first step in designing and developing a PCA, as investigating its social acceptability is a prerequisite before actual implementation. Key policy insightsLarge intergenerational differences in the social acceptability of a PCA exist, with younger people strongly in favour.Carbon price regulations increase social acceptability, either through minimum and maximum prices or through a fixed price by experts.Provision of tailor-made advice to reduce personal carbon impact increases social acceptability.Introduction of purchase limits for emission thresholds, beyond which a tax is imposed, needs to be complemented by additional measures to ensure climate justice.

description: Knowledge of the equation of state of the baryon matter plays a decisive role in the description of neutron stars. With an increase of the baryon density the filling of Fermi seas of hyperons and $Δ$ isobars becomes possible. Their inclusion into standard relativistic mean-field models results in a strong softening of the equation of state and a lowering of the maximum neutron star mass below the measured values. We extend a relativistic mean-field model with scaled hadron masses and coupling constants developed in our previous works and take into account now not only hyperons but also the $Δ$ isobars. We analyze available empirical information to put constraints on coupling constants of $Δ$s to mesonic mean fields. We show that the resulting equation of state satisfies majority of presently known experimental constraints.

description: Reliable and validated assessments of introductory physics have been instrumental in driving curricular and pedagogical reforms that lead to improved student learning. As part of an effort to systematically improve our sophomore-level Classical Mechanics and Math Methods course (CM 1) at CU Boulder, we have developed a tool to assess student learning of CM 1 concepts in the upper-division. The Colorado Classical Mechanics/Math Methods Instrument (CCMI) builds on faculty consensus learning goals and systematic observations of student difficulties. The result is a 9-question open-ended post-test that probes student learning in the first half of a two-semester classical mechanics / math methods sequence. In this paper, we describe the design and development of this instrument, its validation, and measurements made in classes at CU Boulder and elsewhere.

description: Dixon's famous theorem states that the group generated by two random permutations of a finite set is generically either the whole symmetric group or the alternating group. In the context of random generation of finite groups this means that it is hopeless to wish for a uniform distribution -- or even a non-trivial one -- by drawing random permutations and looking at the generated group. Mealy automata are a powerful tool to generate groups, including all finite groups and many interesting infinite ones, whence the idea of generating random finite groups by drawing random Mealy automata. In this paper we show that, for a special class of Mealy automata that generate only finite groups, the distribution is far from being uniform since the obtained groups are generically a semi-direct product between a direct product of alternating groups and a group generated by a tuple of transpositions.

description: Numerical simulations of 3D, rapidly rotating Rayleigh-Benard convection are performed using an asymptotic quasi-geostrophic model that incorporates the effects of no-slip boundaries through (i) parameterized Ekman pumping boundary conditions, and (ii) a thermal wind boundary layer that regularizes the enhanced thermal fluctuations induced by pumping. The fidelity of the model, obtained by an asymptotic reduction of the Navier-Stokes equations that implicitly enforces a pointwise geostrophic balance, is explored for the first time by comparisons of simulations against the findings of direct numerical simulations and laboratory experiments. Results from these methods have established Ekman pumping as the mechanism responsible for significantly enhancing the vertical heat transport. This asymptotic model demonstrates excellent agreement over a range of thermal forcing for Pr ~1 when compared with results from experiments and DNS at maximal values of their attainable rotation rates, as measured by the Ekman number (E ~ 10^{-7}); good qualitative agreement is achieved for Pr > 1. Similar to studies with stress-free boundaries, four spatially distinct flow morphologies exists. Despite the presence of frictional drag at the upper and/or lower boundaries, a strong non-local inverse cascade of barotropic (i.e., depth-independent) kinetic energy persists in the final regime of geostrophic turbulence and is dominant at large scales. For mixed no-slip/stress-free and no-slip/no-slip boundaries, Ekman friction is found to attenuate the efficiency of the upscale energy transport and, unlike the case of stress-free boundaries, rapidly saturates the barotropic kinetic energy. For no-slip/no-slip boundaries, Ekman friction is strong enough to prevent the development of a coherent dipole vortex condensate. Instead vortex pairs are found to be intermittent, varying in both time and strength.

description: In further pursuit of the diagonalizable \emph{real nonnegative inverse eigenvalue problem} (RNIEP), we study the relationship between the \emph{row cone} $\mathcal{C}_r(S)$ and the \emph{spectracone} $\mathcal{C}(S)$ of a Perron similarity $S$. In the process, a new kind of matrix, \emph{row Hadamard conic} (RHC), is defined and related to the D-RNIEP. Characterizations are given when $\mathcal{C}_r(S) = \mathcal{C}(S)$, and explicit examples are given for all possible set-theoretic relationships between the two cones. The symmetric NIEP is the special case of the D-RNIEP in which the Perron similarity $S$ is also orthogonal.

description: The production of a strongly interacting medium in heavy-ion collisions is identified through suppression of high transverse momentum jets leading to an effect known as jet quenching. Detailed measurements of nuclear modification factors and energy flow of the aforementioned quenched jets are performed with the CMS detector. These new results extend previous measurements to large angles with respect to the quenched jets and increase reach in the transverse momentum range. High statistics pp, pPb and PbPb data taken in 2011-13 are used in the following analysis. A new data-driven method to estimate the underlying event contribution from the forward calorimeter energy distribution is employed which takes into account possible event by event flow modulation. The flavor dependence of energy loss of jets is studied by tagging heavy flavor b-jets in these systems.

description: When magnons and phonons, the fundamental quasiparticles of the solid, are coupled to one another, they form a new hybrid quasi-particle, leading to novel phenomena and interesting applications. Despite its wide-ranging importance, however, detailed experimental studies on the underlying Hamiltonian is rare for actual materials. Moreover, the anharmonicity of such magnetoelastic excitations remains largely unexplored although it is essential for a proper understanding of their diverse thermodynamic behaviour as well as intrinsic zero-temperature decay. Here we show that in noncollinear antiferromagnets, a strong magnon-phonon coupling can significantly enhance the anharmonicity, resulting in the creation of magnetoelastic excitations and their spontaneous decay. By measuring the spin waves over the full Brillouin zone and carrying out anharmonic spin wave calculations using a Hamiltonian with an explicit magnon-phonon coupling, we have identified a hybrid magnetoelastic mode in (Y,Lu)MnO3 and quantified its decay rate and the exchange-striction coupling term required to produce it. Our work has wide implications for understanding of the spin-phonon coupling and the resulting excitations of the broad classes of noncollinear magnets.

description: Conditions for the appearance of topological charges are studied in the framework of the universal C*-algebra of the electromagnetic field, which is represented in any theory describing electromagnetism. It is shown that non-trivial topological charges, described by pairs of fields localised in certain topologically non-trivial spacelike separated regions, can appear in regular representations of the algebra only if the fields depend non-linearly on the mollifying test functions. On the other hand, examples of regular vacuum representations with non-trivial topological charges are constructed, where the underlying field still satisfies a weakened form of "spacelike linearity". Such representations also appear in the presence of electric currents. The status of topological charges in theories with several types of electromagnetic fields, which appear in the short distance (scaling) limit of asymptotically free non-abelian gauge theories, is also briefly discussed.

description: Political polarization in the US hinders bipartisan support for carbon taxes. Polarization operates unconsciously via implicit biases (implicit level), but it also arises when individuals consciously reflect on their political identity and beliefs (explicit level). We conducted two survey experiments with online panels of the US population to examine how irreconcilable Democrats’ and Republicans’ views on carbon taxes are. Study 1 compared measurements from an Implicit Association Test (implicit level) and stated beliefs (explicit level). Results show carbon tax fairness perceptions were already polarized at implicit level, but the main divergence in attitudes occurred at explicit level. Since explicit attitudes are considered easier to influence than implicit ones, Study 2 tested the extent to which message framing could influence this deliberated—explicit—polarization. We used different frames targeted at Democrats and Republicans to convey the idea that carbon tax support does not threaten partisans’ political identity. Framings further polarized responses, increasing Democrats’ but reducing Republicans’ policy support. We discuss implications for climate policy communication in relation to navigating identity-based polarization. Policy HighlightsPolitical polarization over climate policy in the US is driven by the interplay of affective and cognitive factors.Unconscious fairness perceptions about carbon taxes are already polarized. These differences amplify when Democrats and Republicans consciously report their perceptions.Identity-affirming framings that appeal to partisans’ concerns can influence carbon tax acceptance.Since Republicans may react negatively to climate policy communication, source credibility might be necessary to avoid backlash.
