description: Numerous phenomenological parallels have been drawn between f- and d- electron systems in an attempt to understand their display of unconventional superconductivity. The microscopics of how electrons evolve from participation in large moment antiferromagnetism to superconductivity in these systems, however, remains a mystery. Knowing the origin of Cooper paired electrons in momentum space is a crucial prerequisite for understanding the pairing mechanism. Of especial interest are pressure-induced superconductors CeIn3 and CeRhIn5 in which disparate magnetic and superconducting orders apparently coexist - arising from within the same f-electron degrees of freedom. Here we present ambient pressure quantum oscillation measurements on CeIn3 that crucially identify the electronic structure - potentially similar to high temperature superconductors. Heavy pockets of f-character are revealed in CeIn3, undergoing an unexpected effective mass divergence well before the antiferromagnetic critical field. We thus uncover the softening of a branch of quasiparticle excitations located away from the traditional spin-fluctuation dominated antiferromagnetic quantum critical point. The observed Fermi surface of dispersive f-electrons in CeIn3 could potentially explain the emergence of Cooper pairs from within a strong moment antiferromagnet.

title: Identity, visibility and legitimacy in Turkish Cypriot tourism development
Creators: name: Scott, Julie
Publisher: name: University of Kent
Year: 2021

description: Since the division of Cyprus in 1974, political, cultural and economic means have been used to underpin and legitimise the conflicting national claims of the Greek and Turkish Cypriot communities. Turkish Cypriot efforts to develop tourism in the north and to market Northern Cyprus as a tourist attraction highlight the contested identity of Cyprus and place of Turkish Cypriots in its past, present and future. The aim of this thesis is to explore the issues of Turkish Cypriot identity, visibility and legitimacy through the lens of tourism development in the north. Access to the capital resources of land and finance; business relationships and job-seeking behaviour; and the packaging of local culture and the construction of history and landscape for tourists, are all analysed in terms of their relevance to the goal of 'tanitma' [lit: "making known"], which is a central concept in Turkish Cypriot tourism development, and which can be understood in three ways: as the activity of marketing and promoting tourism in Northern Cyprus; as the goal of gaining international recognition for the existence of a Turkish Cypriot political, social and cultural entity; and as the project of creating and making known to its own citizens as a Turkish Cypriot state based simultaneously on the idea of historical continuity - the long-standing presence of Turks in Cyprus and their cultural imprint on the island - with discontinuity - the creation of a Turkish Cypriot state in the north. The thesis also incorporates an examination of the relationship between tourism and anthropological theory in order to offer a critique of models of culture, identity and causation which feature widely in the tourism literature. I examine the encounter between the "professionalised" international tourism sector and internal social networks; between "hosts" and "guests"; and between locals and migrant workers; and discuss how the meanings generated by these encounters illuminate the issues of identity, culture and boundaries, and the categories of "inside" and "outside".
The kink-type instability of toroidal stellar magnetic fields with thermal diffusion

Year: 2009
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: The stability of toroidal magnetic fields in rotating radiative stellar zones is studied for realistic values of both the Prandtl numbers. The two considered models for the magnetic geometry represent fields with odd and even symmetry with respect to the equator. In the linear theory in Boussinesq approximation the resulting complex eigenfrequency (including growth rate and drift rate) are calculated for a given radial wavenumber of a nonaxisymmetric perturbation with m=1. The ratio of the Alfven frequency, Ω_A, to the rate of the basic rotation, Ω, controls the eigenfrequency of the solution. For strong fields with Ω_A > Ωthe solutions do not feel the thermal diffusion. The growth rate runs with Ω_A and the drift rate is close to -Ωso that the magnetic pattern will rest in the laboratory system. For weaker fields with Ω_A < Ωthe growth rate strongly depends on the thermal conductivity. For fields with dipolar parity and for typical values of the heat conductivity the resulting very small growth rates are almost identical with those for vanishing gravity. For fields with dipolar symmetry the differential rotation of any stellar radiative zone (like the solar tachocline) is shown as basically stabilizing the instability independent of the sign of the shear. Finally, the current-driven kink-type instability of a toroidal background field is proposed as a model for the magnetism of Ap stars. The recent observation of a lower magnetic field treshold of about 300 Gauss for Ap stars is understood as corresponding to the minimum magnetic field producing the instability.

description: Natural and man-made disasters are becoming more prevalent and increasing in danger as climate change continues unabated and resources get scarce. Whether it be flood or terrorism, disasters displace people and it remains difficult to reach those in need when the disaster does strike. For years, mobile phone networks have been integral in responding to emergencies, but they rely on costly infrastructure that is prone to outages or outright attack. We propose a long-range, low-power mesh network infrastructure based on a new, still-developing networking protocol and embedded software implementation that seeks to fill the need of disaster communications telemetry gathering for a fraction of the cost of mobile phone networking infrastructure such as 4G LTE or 5G. While the protocol is simple, it was found to have an inadequate implementation at this stage. Error rates were high and bugs were found in implementation that led to an abnormal amount of time spent processing corrupted data, though power consumption was encouraging in spite of these conditions. We examine the strengths and weaknesses of this new protocol and suggest improvements to harden the implementation.
Real property tax assessments : an examination of the consequences of a departure from the specified basis of assessment
Creators: name: Leigh, Clive Michael
Publisher: name: University of British Columbia
Year: 2011

description: The real property tax plays a significant part in the fiscal systems of the United Kingdom and Canada; and it is important that the burden of the tax is distributed according to the wishes of the legislature. Generally, the liability to the tax varies with the 'value' of real property owned or occupied by the taxpayer; but 'value' is a term that requires definition. Where the interpretation of the term by the assessors differs from the legal definition, the distribution of the tax burden will differ from that desired. In addition, a conflict will exist with each new assessment between adopting the assessor's interpretation of the 'value' concept and adopting the legal definition. The examination of these problems is not limited to the context of any one particular jurisdiction, but reference is made to the situation in England and Wales, and in Canada. It is shown that the legislature has many alternatives available when adopting a basis of assessment and the bases adopted in British Columbia and England and Wales are examined as examples. If the current assessments differ from those required by law, the assessor has, in practice, a number of alternatives available for the maintenance of the roll between revaluations. These are considered. It is seen that only where there is a constant relationship between existing assessments and those required by law, will the distribution of the tax burden be correct. In other cases inequality will result and measures of the extent of this inequality are proposed. The conflict between the meanings of 'value' to be adopted for new assessments will depend on the definitions laid down by Statute and by the judiciary; on the meaning adopted by the assessor; and on the legal provisions for uniformity of treatment. Examples of the legal provisions for uniformity of treatment in England and Wales and in Canada are examined but no universal solution to the conflict is produced. Instead it is suggested that new properties be brought onto the roll at figures which would improve the distribution of the tax burden. Finally in view of the imperfections in the real property tax, alternative treatments for its improvement are summarised.
A tight-binding approach to uniaxial strain in graphene

description: We analyze the effect of tensional strain in the electronic structure of graphene. In the absence of electron-electron interactions, within linear elasticity theory, and a tight-binding approach, we observe that strain can generate a bulk spectral gap. However this gap is critical, requiring threshold deformations in excess of 20%, and only along preferred directions with respect to the underlying lattice. The gapless Dirac spectrum is robust for small and moderate deformations, and the gap appears as a consequence of the merging of the two inequivalent Dirac points, only under considerable deformations of the lattice. We discuss how strain-induced anisotropy and local deformations can be used as a means to affect transport characteristics and pinch off current flow in graphene devices.

description: Accurately capturing the three dimensional power distribution within a reactor core is vital for ensuring the safe and economical operation of the reactor, compliance with Technical Specifications, and fuel cycle planning (safety, control, and performance evaluation). Offline (that is, during cycle planning and core design), a three dimensional neutronics simulator is used to estimate the reactor's power, moderator, void, and flow distributions, from which margin to thermal limits and fuel exposures can be approximated. Online, this is accomplished with a system of local power range monitors (LPRMs) designed to capture enough neutron flux information to infer the full nodal power distribution. Certain problems with this process, ranging from measurement and calibration to the power adaption process, pose challenges to operators and limit the ability to design reload cores economically (e.g., engineering in insufficient margin or more margin than required). Artificial intelligence (AI) and machine learning (ML) are being used to solve the problems to reduce maintenance costs, improve the accuracy of online local power measurements, and decrease the bias between offline and online power distributions, thereby leading to a greater ability to design safe and economical reload cores. We present ML models trained from two deep neural network (DNN) architectures, SurrogateNet and LPRMNet, that demonstrate a testing error of 1 percent and 3 percent, respectively. Applications of these models can include virtual sensing capability for bypassed or malfunctioning LPRMs, on demand virtual calibration of detectors between successive calibrations, highly accurate nuclear end of life determinations for LPRMs, and reduced bias between measured and predicted power distributions within the core.

Morphological Structures of Planetary Nebulae

Publisher: name: arXiv
Year: 2009
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Since various structural components of planetary nebulae manifest themselves differently, a combination of optical, infrared, submm, and radio techniques is needed to derive a complete picture of planetary nebulae. The effects of projection can also make the derivation of the true 3-D structure difficult. Using a number of examples, we show that bipolar and multipolar nebulae are much more common than usually inferred from morphological classifications of apparent structures of planetary nebulae. We put forward a new hypothesis that the bipolar and multipolar lobes of PN are not regions of high-density ejected matter, but the result of ionization and illumination. The visible bright regions are in fact volume of low densities (cleared by high-velocity outflows) where the UV photons are being channelled through. We suggest that multipolar nebulae with similar lobe sizes are not caused by simultaneous ejection of matter in several directions, but by leakage of UV photons into those directions.

description: We propose a universal elastic energy for proteins, which depends only on the radius of gyration $R_{g}$ and the residue number $N$. It is constructed using physical arguments based on the hydrophobic effect and hydrogen bonding. Adjustable parameters are fitted to data from the computer simulation of the folding of a set of proteins using the CSAW (conditioned self-avoiding walk) model. The elastic energy gives rise to scaling relations of the form $R_{g}\sim N^ν$ in different regions. It shows three folding stages characterized by the progression with exponents $ν= 3/5, 3/7, 2/5$, which we identify as the unfolded stage, pre-globule, and molten globule, respectively. The pre-globule goes over to the molten globule via a break in behavior akin to a first-order phase transition, which is initiated by a sudden acceleration of hydrogen bonding.
The CKM suppressed $B(B_s) \to \bar D_{(s)}P,\bar D_{(s)}V,\bar D_{(s)}^*P, \bar D_{(s)}^*V$ decays in perturbative QCD approach

description: Although the two-body charmed decays $B_{(s)} \to \bar D_{(s)}^{(*)}P$ and $\bar D_{(s)}^{(*)}V$, where $P$($V$) denotes a light pseudoscalar(vector) meson, are CKM suppressed comparing with the $B_{(s)} \to D_{(s)}^{(*)}P$ and $ D_{(s)}^{(*)}V$ decays, they are important in the CKM angle $γ=ϕ_3$ extraction method. We investigated these decays in the perturbative QCD approach to the leading order of $m_D/m_B$ and $Λ_{\rm{QCD}}/m_D$ expansion. We find that the nonfactorizable emission diagrams and the annihilation diagrams are not negligible in many of these channels. The numerical results show that most channels have branching ratios with an order of $10^{-6}$ or $10^{-7}$. The ratio needed for the CKM angle $γ$ extraction is estimated as $r = \frac{|A(B^- \to \bar{D}^0 K^-)|}{|A(B^- \to D^0 K^-)|} = 0.092_{-0.003-0.003}^{+0.012+0.003},$ which is too small for the experiments. Some of the $ B_{(s)}\to \bar D_{(s)}^*V$ decays have a very large transversely polarized contribution that can reach 80%.

description: This paper presents a cross-layer approach to jointly design adaptive modulation and coding (AMC) at the physical layer and cooperative truncated automatic repeat request (ARQ) protocol at the data link layer. We first derive an exact closed form expression for the spectral efficiency of the proposed joint AMC-cooperative ARQ scheme. Aiming at maximizing this system performance measure, we then optimize an AMC scheme which directly satisfies a prescribed packet loss rate constraint at the data-link layer. The results indicate that utilizing cooperative ARQ as a retransmission strategy, noticeably enhances the spectral efficiency compared with the system that employs AMC alone at the physical layer. Moreover, the proposed adaptive rate cooperative ARQ scheme outperforms the fixed rate counterpart when the transmission modes at the source and relay are chosen based on the channel statistics. This in turn quantifies the possible gain achieved by joint design of AMC and ARQ in wireless relay networks.

description: We report optical B-band observations with the Large Binocular Telescope LBT of the isolated neutron star RBS1774. The stacked image with total exposure 2.5h reveals a candidate optical counterpart at mB = 26.96 +- 0.20 at position RA(2000) = 21:43:03.4, DEC(2000)} = +06:54:17:5, within the joint Chandra and XMM-Newton error circles. We analyse archival XMM-Newton observations and derive revised spectral and positional parameters. The predicted optical flux from the extrapolated X-ray spectrum is likely twice as high as reported before. The measured optical flux exceeds the extrapolated X-ray spectral flux by a factor ~40 (15 - 60 at 1sigma confidence). We interpret our detection and the spectral energy distribution as further evidence of a temperature structure over the neutron star's surface and present a pure thermal model reflecting both the SED and the pulsed fraction of the light curve.

description: This paper discusses the thermodynamics of a black hole with respect to Hawking radiation and the entropy. We look at a unified picture of black hole entropy and curvature and how this can lead to the usual black hole luminosity due to Hawking radiation. It is also shown how the volume inside the horizon, apart from surface area, can play a role in understanding the Hawking flux. In addition holography also implies a phase space associated with the interior volume and this happens to be just a quantum of phase space, filled with just one photon. Generalised uncertainty principle can be incorporated in this analysis. These results hold for all black hole masses in any dimensions.

title: Static analysis of Martin-Löf's intuitionistic type theory
Creators: name: Telford, Alastair J.
Publisher: name: University of Kent
Year: 2021

description: Martin-Löf's intuitionistic type theory has been under investigation in recent years as a potential source for future functional programming languages. This is due to its properties which greatly aid the derivation of provably correct programs. These include the Curry-Howard correspondence (whereby logical formulas may be seen as specifications and proofs of logical formulas as programs) and strong normalisation (i.e. evaluation of every proof/program must terminate). Unfortunately, a corollary of these properties is that the programs may contain computationally irrelevant proof objects: proofs which are not to be printed as part of the result of a program. We show how a series of static analyses may be used to improve the efficiency of type theory as a lazy functional programming language. In particular we show how variants of abstract interpretation may be used to eliminate unnecessary computations in the object code that results from a type theoretic program. After an informal treatment of the application of abstract interpretation to type theory (where we discuss the features of type theory which make it particularly amenable to such an approach), we give formal proofs of correctness of our abstract interpretation techniques, with regard to the semantics of type theory. We subsequently describe how we have implemented abstract interpretation techniques within the Ferdinand functional language compiler. Ferdinand was developed as a lazy functional programming system by Andrew Douglas at the University of Kent at Canterbury. Finally, we show how other static analysis techniques may be applied to type theory. Some of these techniques use the abstract interpretation mechanisms previously discussed.
Mini-Workshop: Adaptive Methods for Control Problems Constrained by Time-Dependent PDEs

Publisher: name: Zürich : EMS Publ. House
Year: 2017
Subjects: subject: Konferenzschrift
subject: 510

description: Optimization problems constrained by time-dependent PDEs (Partial Differential Equations) are challenging from a computational point of view: even in the simplest case, one needs to solve a system of PDEs coupled globally in time and space for the unknown solutions (the state, the costate and the control of the system). Typical and practically relevant examples are the control of nonlinear heat equations as they appear in laser hardening or the thermic control of flow problems (Boussinesq equations). Specifically for PDEs with a long time horizon, conventional time-stepping methods require an enormous storage of the respective other variables. In contrast, adaptive methods aim at distributing the available degrees of freedom in an a-posteriori-fashion to capture singularities and are, therefore, most promising.

description: Wave packets provide a well established and versatile tool for studying time-dependent effects in molecular physics. Here, we demonstrate the application of wave packets to mesoscopic nanodevices at low temperatures. The electronic transport in the devices is expressed in terms of scattering and transmission coefficients, which are efficiently obtained by solving an initial value problem (IVP) using the time-dependent Schroedinger equation. The formulation as an IVP makes non-trivial device topologies accessible and by tuning the wave packet parameters one can extract the scattering properties for a large range of energies.

description: The expression for the spin susceptibility $χ$ of degenerate quark matter is derived with corrections upto $ {\cal O}(g^4\ln g^2)$. It is shown that at low density, $χ^{-1}$ changes sign and turns negative indicating a ferromagnetic phase transition. To this order, we also calculate sound velocity $c_1$ and incompressibility $K$ with arbitrary spin polarization. The estimated values of $c_1$ and $K$ show that the equation of state of the polarized matter is stiffer than the unpolarized one. Finally we determine the finite temperature corrections to the exchange energy and derive corresponding results for the spin susceptibility.

It is shown that the inclusion of drift current of conduction electrons into the model of dielectric response results in contradictions with both thermodynamics and experimental data of different experimental groups. Physical reasons why the problems and paradoxes arise are analyzed and found to be connected with the violation of basic applicability condition of the Lifshitz theory, the thermal equilibrium. A recent alternative approach to the resolution of the problems based on the inclusion of screening effects and diffusion current is considered and demonstrated to be thermodynamically and experimentally inconsistent. It is argued that the inclusion of the diffusion current leads to an even deeper violation of thermal equilibrium. Phenomenologically, the Lifshitz theory with role of drift and diffusion currents neglected is shown to be free of problems and in agreement with both thermodynamics and all available experimental data.

description: We report the results of a time-series CCD photometric survey of variable stars in the field of the open cluster NGC 2126. In about one square degree field covering the cluster, a total number of 21 variable candidates are detected during this survey, of which 16 are newly found. The periods, classifications and spectral types of 14 newly discovered variables are discussed, which consist of six eclipsing binaries systems, three pulsating variable stars, three long period variables, one RS CVn star, and one W UMa or $δ$ Scuti star. In addition, there are two variable candidates, the properties of which cannot be determined in this paper. By a method based on fitting spectral energy distributions(SEDs) of stars with theoretical ones, the membership probabilities and the fundamental parameters of this cluster are determined. As a result, five variables are probably members of NGC 2126. The fundamental parameters of the this cluster are determined as: the metallicity to be 0.008 $Z_\odot$, the age $\log(t)$= 8.95, the distance modulus $(m-M)_{0}$= 10.34 and the reddening value $E(B-V)$=0.55 mag.

description: The workshop brought together leading experts and young researchers at the interface of automorphic forms and analytic number theory to disseminate, discuss and develop important recent methods and results. A particular focus was on higher rank groups, as well as their arithmetic applications. This includes, for instance, the study of various aspects of $L$-functions, the fine distribution properties of their Fourier coefficients and Hecke eigenvalues, the mass distribution of automorphic forms on general symmetric spaces, and applications of results of algebraic geometry to automorphic forms.

description: A superconducting ring with a pi junction made from superconductor/ferromagnetic-metal/superconductor (S-FM-S) exhibits a spontaneous current without an external magnetic field in the ground state. Such pi ring provides so-called quiet qubit that can be efficiently decoupled from the fluctuation of the external field. However, the usage of the FM gives rise to strong Ohmic dissipation. Therefore, the realization of pi junctions without FM is expected for qubit applications. We theoretically consider the possibility of the pi coupling for S/Eu-chalcogenides/S junctions based on the d-f Hamiltonian. By use of the Green's function method we found that pi junction can be formed in the case of the finite d-f hybridization between the conduction d and the localized f electrons.

description: Exact numerical results for the full counting statistics (FCS) of a one-dimensional tight-binding model of noninteracting electrons are presented at finite temperatures using an identity recently presented by Abanov and Ivanov. A similar idea is used to derive a new expression for the cumulant generating function for a system consisting of two quasi-one-dimensional leads connected by a quantum dot in the long time limit. This provides a generalization of the Levitov-Lesovik formula for such systems.

Pressure leaching of copper sulphides in perchloric acid solutions
Creators: name: Loewen, Fred
Publisher: name: University of British Columbia

description: The leaching of covellite (CuS), chalcocite (Cu₂S), chalcopyrite (CuFeS₂) and bornite (Cu₅FeS₄) was carried out in a shaking autoclave in perchloric acid solutions and using moderate pressures of oxygen. The temperature range of investigation was 105-140°C. It was found that covellite, chalcocite and bornite leach at approximately similar rates, with chalcopyrite being an order of magnitude slower. It was found that chalcocite leaching can be divided into two stages, first, the rapid transformation to covellite with an activation energy 1.8 Kcal/mole, followed by a slower oxidation stage identified as covellite-dissolution with an activation energy of 11.4 Kcal/ mole. These two stages of leaching were also observed in bornite with chalcocite (or digenite) appearing as an intermediate step. No such, transformations were observed in covellite or chalcopyrite. Two separate reactions were recognized as occuring simultaneously for all four minerals during the oxidation process: an electrochemical reaction yielding elemental sulphur and creating pits on the mineral surface, and a chemical reaction producing sulphate. The first reaction dominates in strongly acidic conditions, being responsible for about. 85% of the sulphur released from the mineral, but the sulphate to elemental sulphur ratio in solution increases with decreasing acidity. Above 120°C the general oxidation process is inhibited by molten sulphur coating the mineral particles; the sulphate producing reaction, however, is not reduced above this temperature. For chalcopyrite the activation energies for the sulphate producing reaction and mineral solubilized were found to be 16.0 Kcal/mole and 11.0 Kcal/mole, respectively. It is suggested that chalcopyrite may leach partially via the .formation of transient covellite on the surface but since its leaching rate is faster than that for chalcopyrite, no covellite is detected after leaching.

description: Cultural translation is a holistic process. The analysis of this process demands a critique that is similarly holistic which proposes that a translation can be examined from the perspectives of translators, documents, and readers. The present study purposes to demonstrate that this three-part critique is crucially interrelated in the English translation of Madurese cultural texts. To do this, in-depth interviews, document analysis, and questionnaire distribution were applied. The results reveal the translators’ competence of translation processes in practice and the readers’ responses regarding work of translation play a significant role in the performance of the translation task of Madurese cultural texts.

description: We consider flux-corrected finite element discretizations of 3D convection-dominated transport problems and assess the computational efficiency of algorithms based on such approximations. The methods under investigation include flux-corrected transport schemes and monolithic limiters. We discretize in space using a continuous Galerkin method and P1 or Q1 finite elements. Time integration is performed using the Crank-Nicolson method or an explicit strong stability preserving Runge-Kutta method. Nonlinear systems are solved using a fixed-point iteration method, which requires solution of large linear systems at each iteration or time step. The great variety of options in the choice of discretization methods and solver components calls for a dedicated comparative study of existing approaches. To perform such a study, we define new 3D test problems for time dependent and stationary convection-diffusion-reaction equations. The results of our numerical experiments illustrate how the limiting technique, time discretization and solver impact on the overall performance.
Simultaneous observations of a pair of kilohertz QPOs and a plausible 1860 Hz QPO from an accreting neutron star system

description: We report an indication (3.22 sigma) of ~ 1860 Hz quasi-periodic oscillations from a neutron star low-mass X-ray binary 4U 1636-536. If confirmed, this will be by far the highest frequency feature observed from an accreting neutron star system, and hence could be very useful to understand such systems. This plausible timing feature was observed simultaneously with lower (~ 585 Hz) and upper (~ 904 Hz) kilohertz quasi-periodic oscillations. The two kilohertz quasi-periodic oscillation frequencies had the ratio of ~ 1.5, and the frequency of the alleged ~ 1860 Hz feature was close to the triple and the double of these frequencies. This can be useful to constrain the models of all the three features. In particular, the ~ 1860 Hz feature could be (1) from a new and heretofore unknown class of quasi-periodic oscillations, or (2) the first observed overtone of lower or upper kilohertz quasi-periodic oscillations. Finally we note that, although the relatively low significance of the ~ 1860 Hz feature argues for caution, even a 3.22 sigma feature at such a uniquely high frequency should be interesting enough to spur a systematic search in the archival data, as well as to scientifically motivate sufficiently large timing instruments for the next generation X-ray missions.
