description: The rare decay $B^0 \to ϕϕ$ can occur only via penguin annihilation topology in the standard model. We calculate this channel in the perturbative QCD approach. The predicted branching ratio is very small at ($10^{-8}$). We also give the polarization fractions, which shows that the transverse polarization contribution is comparable to the longitudinal one, due to a big transverse contribution from factorizable diagrams. The small branching ratio in SM, makes it sensitive to any new physics contributions.

Customary law, the Crown and the common law : ancient legal islands in the post-colonial stream
Creators: name: Pesklevits, Richard Dale
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is a cross-disciplinary study of legal history and customary law. Respect for, and accommodation of local customary law has been a constant and integral feature of law in Britain since Anglo-Saxon times. It guided the emergence of the common law, and continues as a rule of law to the present day. Such respect and accommodation was an essential principle that permitted the peaceful consolidation of the British realms from its constituent parts. Continuity of law is a legal presumption whether territories have been added by conquest, cession or annexation. The principle respect for local legal custom was one of two schools of thought carried to Britain's overseas colonies; the other was a theory that local customary law could be extinguished by non-recognition on the part of the British sovereign or his/her delegates. Nevertheless, customary laws and institutions were explicitly and implicitly recognized in the colonial period. The doctrine has modern application with respect to the customary law ways of indigenous peoples wherever the common law has been extended overseas. Rights under customary law are distinguished from Aboriginal rights, though there is some overlap between the two. Customary law can only be extinguished by an express statute, or by clearly unavoidable implication. Legal customs are not invalid merely for being contrary to the common law. Common law defers to valid customary law as a matter of constitutional common law. But the common law provides tests by which courts can identify valid legal custom. Where a valid, unextinguished legal custom is found, courts are bound by the common law to apply it. Where customary law can be identified, it binds the servants and agents of the Crown, except when it is inconsistent with Crown sovereignty itself.

description: On the basis of the generalization of the theorem about K-odd operators (K is the Dirac's operator), certain linear combination is constructed, which appears to commute with the Dirac Hamiltonian for Coulomb field. This operator coincides with the Johnson and Lippmann operator and is intimately connected to the familiar Laplace-Runge-Lenz vector. Our approach guarantees not only derivation of Johnson-Lippmann operator, but simultaneously commutativity with the Dirac Hamiltonian follows.

Generalized Radar 4-Coordinates and Equal-Time Cauchy Surfaces for Arbitrary Accelerated Observers

description: All existing 4-coordinate systems centered on the world-line of an accelerated observer are only locally defined like it happens for Fermi coordinates both in special and general relativity. As a consequence, it is not known how non-inertial observers can build {\it equal-time surfaces} which a) correspond to a conventional observer-dependent definition of synchronization of distant clocks; b) are good Cauchy surfaces for Maxwell equations. Another type of coordinate singularities are those connected to the relativistic rotating coordinate systems (the rotating disk).We show that the use of Hamiltonian methods based on 3+1 splittings of space-time allows to define as many observer-dependent globally defined radar 4-coordinate systems as nice foliations of space-time with space-like hyper-surfaces admissible according to M$ø$ller (for instance only differentially rotating relativistic coordinate system are allowed). All these conventional notions of an {\it instantaneous 3-space} for an arbitrary observer can be empirically defined by introducing generalizations of Einstein ${1\over 2}$ convention for clock synchronization in inertial frames. Each admissible 3+1 splitting corresponds to a non-rigid non-inertial frame centered on the observer. When there is a Lagrangian description of an isolated relativistic system, its reformulation as a parametrized Minkowski theory allows to show that all the admissible synchronization conventions are {\it gauge equivalent}, as it also happens in canonical metric and tetrad gravity, where, however, the chrono-geometrical structure of space-time is dynamically determined.

description: The joint conference paper, 'Third-party effects of water trading and potential policy responses' by Anna Heaney (ABARE), Gavan Dwyer (PC), Stephen Beare (ABARE), Deborah Peterson (PC) and Lili Pechey (ABARE), was presented to the American Agricultural Economics Association conference, Providence, Rhode Island, 25 - 27 July 2005. A key feature of water policy reform in Australia has been the separation of water access entitlements from land titles and the establishment of markets for water. However, the separation of water entitlements from land entitlement is not a sufficient condition to ensure that water markets are complete. In the absence of fully defined property rights, water markets will be incomplete and trade has the potential to create third-party effects. However, property rights over natural resources are seldom completely specified, because of the existence of transactions costs. The benefits from eliminating third-party effects need to be sufficient to warrant intervention. The objectives in this paper are to identify key potential third-party effects of water trade under existing property rights structures in Australia, and to examine policy responses to address these effects. The discussion draws on the concepts of exclusiveness and rivalry as key characteristics that determine the applicability of property rights solutions to third-party effects of trade. It is likely that many of the third-party effects of trade discussed in this paper do not warrant policy intervention at the national or state level. In some instances, effects are likely to be relatively minor, although some may be significant at the local level. The costs of addressing some third-party effects may outweigh the benefits. Where there are significant gains from trade, the existence of these third-party effects should not been seen as a reason to impede trade. There are first-best policy instruments to address these effects at an appropriate scale. *ABARE (Australian Bureau of Agricultural and Resource Economics); PC (Productivity Commission) **The views expressed in this paper do not necessarily reflect those of the Productivity Commission.
Testing the Friedmannian magnitude-redshift relation with SNIa data

Publisher: name: arXiv

description: Standard cosmology is constructed upon the (generally implicit) assumption of the ``large scale'' homogeneity of our Universe. Now, structures are observed at scales which become larger and larger as the observational distances increase. However, the homogeneous Friedmann-Lemaitre-Robertson-Walker model remains a cosmological paradigm, and Friedmannian relations are usually used to work out the model, implicitly assuming that the homogeneity assumption is valid at the studied scales. This has been the way the concordance (Lambda-CDM) model came out from the analyses of the SNIa data. Since this model implies the validity of the Friedmannian magnitude-redshift relation at the range of redshifts spaned by the supernovae surveys, it has been proposed some years ago a very simple test of this possible validity, provided the SNIa should be confirmed as standard candles. Since we can hope that the redshifts of the supernovae which will be observed in the years to come will allow such a test to be performed, it would be interesting to find inside the SNIa community some collaborators ready to perform the test.

description: The conference paper, 'Integrating rural and urban water markets in south east Australia: Preliminary analysis' by Gavan Dwyer, Paul Loke, David Appels, Susan Stone and Deborah Peterson, was presented to the OECD Workshop on Agriculture and Water: Sustainability, Markets and Policies Adelaide, 14-18 November 2005. The trade of water in Australia is constrained and generally limited to irrigators, with other industries and households excluded. A regional general equilibrium model of the Australian economy (TERM-Water) is used to undertake a preliminary analysis of the effects of expanding the trade of water in south east Australia to include both irrigators and urban users. The focus is on the urban centres of Adelaide, Canberra and Melbourne, and the major irrigation districts in the southern Murray-Darling Basin and Gippsland. Losses from a hypothetical reduction in water availability to gross regional product and household demand are reduced when water trade is allowed. The extent to which these losses are reduced depends on the extent to which trade is allowed and the differing water uses in each trading region. The results of this preliminary modelling show that net gains are greatest, and the costs to industries and regions are generally more dissipated, when trade is unconstrained. When regions with relatively low levels of water consumption (such as Adelaide and Canberra) face shortfalls in water availability and trade with regions that use large volumes of water (such as irrigators in the southern Murray-Darling Basin), they have little effect on traded prices and quantities. The opposite is true, however, when large water users experience shortages. These broad patterns hold when all regions experience the same hypothetical reduction in water availability. *The views expressed in this paper do not necessarily reflect those of the Productivity Commission.

description: "The Role of Risk and Cost-Benefit Analysis in Determining Quarantine Measures" by Monika Binder, was released on 19 February 2002. Quarantine regimes must conform with World Trade Organization (WTO) requirements arising from the completion of the Uruguay Round of Multilateral Trade Negotiations in 1995. A fundamental aspect of those requirements is the need for a science-based approach to setting measures which potentially restrict trade in animals, plants and their products. This approach is commonly described as import risk analysis (IRA). In some quarters, it is argued that a broad economic perspective should be incorporated in IRAs. This paper looks at the WTO requirements and supporting international guidelines, describes in broad terms the existing IRA approach to determining quarantine measures and addresses some options for improvement and associated problems.

description: "Creating Markets for Biodiversity: A Case Study of Earth Sanctuaries Ltd" by Barbara Aretino, Paula Holland, Deborah Peterson and Michael Schuele was released on 4 September 2001. The study was carried out at the invitation of Environment Australia and the OECD. This paper examines the activities and operations of the first publicly listed company in Australia with wildlife conservation as its primary goal. This paper is the result of a case study of Earth Sanctuaries Ltd who is directly involved in the conservation of biodiversity. The paper found: the private sector can complement conservation activities by the public sector, both by adding to the resources for biodiversity conservation and by freeing up government resources for other purposes. However, arrangements such as wildlife legislation, land tenure and the limited application of the competitive neutrality framework to wildlife sanctuaries can restrict the scope for private firms to conserve biodiversity. All Australian jurisdictions have legislation restricting trade in, and the property rights to, native species which impacts significantly on private sector conservation activities. There also does not appear to be a consistent and coordinated approach across jurisdictions towards private conservation, amplifying uncertainty for organisations which operate in several jurisdictions.

description: Feminist philosophers have long worried that intersectionality undermines the via- bility of the concept and category of woman, thereby undermining feminist theory and politics. Some have responded to this problem by abandoning intersectionality; others have attempted to find some suitably inclusive way of reconceptualizing woman. I provide a novel solution that focuses on conceptualizing oppression in light of intersectionality, rather than trying to provide an account of what it is to be a woman. By enabling us to understand feminism as responding to gender oppression, this ac- count shows that intersectionality does not conceptually undermine and fragment feminism. Feminism should be intersectional.

description: We observe light-induced frequency shifts in one-color photoassociative spectra of magnetically trapped $^4$He$^*$ atoms in the metastable $2^3S_1$ state. A pair of ultracold spin-polarized $2^3S_1$ helium atoms is excited into a molecular bound state in the purely long range $0_u^+$ potential connected to the $2^3S_1 - 2^3P_0$ asymptote. The shift arises from the optical coupling of the molecular excited bound state with the scattering states and the bound states of two colliding $2^3S_1$ atoms. We measure the frequency-shifts for several ro-vibrational levels in the $0^+_u$ potential and find a linear dependence on the photoassociation laser intensity. Comparison with a theoretical analysis provides a good indication for the s-wave scattering length $a$ of the quintet ($^5Σ_g^+$) potential, $a=7.2\pm 0.6$ nm, which is significantly lower than most previous results obtained by non-spectroscopic methods.

description: Interpenetrated polymer network microgels, composed of crosslinked networks of poly(N-isopropylacrylamide) and polyacrylic acid (PAAc), have been investigated through rheological measurements at four different amounts of polyacrylic acid. Both PAAc content and crosslinking degree modify particle dimensions, mass and softness, thereby strongly affecting the volume fraction and the system viscosity. Here the volume fraction is derived from the flow curves at low concentrations by fitting the zero-shear viscosity with the Einstein-Batchelor equation which provides a parameter k to shift weight concentration to volume fraction. We find that particles with higher PAAc content and crosslinker are characterized by a greater value of k and therefore by larger volume fractions when compared to softer particles. The packing fractions obtained from rheological measurements are compared with those from static light scattering for two PAAc contents revealing a good agreement. Moreover, the behaviour of the viscosity as a function of packing fraction, at room temperature, has highlighted an Arrhenius dependence for microgels synthesized with low PAAc content and a Vogel-Fulcher-Tammann dependence for the highest investigated PAAc concentration. A comparison with the hard spheres behaviour indicates a steepest increase of the viscosity with decreasing particles softness. Finally, the volume fraction dependence of the viscosity at a fixed PAAc and at two different temperatures, below and above the volume phase transition, shows a quantitative agreement with the structural relaxation time measured through dynamic light scattering indicating that IPN microgels softness can be tuned with PAAc and temperature and that, depending on particle softness, two different routes are followed.

A step in the pink direction : the intersection of national, familial and sexual identity in Canada
Creators: name: Johnson, Toni A. M.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis explores the intersecting grounds of national, familial and sexual identity in Canada. Each of the three grounds is concentrically connected and therefore feeds and formulates the composition of the other. The thesis considers the ramifications of lesbian and gay inclusion within the family from a queer perspective using anti-essentialist postmodern and feminist theory as tools of deconstruction. Immigration Canada has recently changed the composition of the 'family class' within immigration law to include lesbians and gay men. I consider how this shift in definition affects lesbians and gay men and lesbian and gay families in terms of sexual identity bearing on familial identity, and familial identity bearing on national identity. The connections begin by considering a deconstructed version of national identity. National identity from a legal perspective has been formulated predominantly on a basis of white, heterosexual masculinity. By highlighting the incoherence and alterity that exists within the formulation of a stereotypical nationalist narrative of identity, we are able to identify the fallacious basis of nationalistic constructs of identity. Feeding this national identity has been a construct of the family, a fundamental unit of society, which has not represented the multiplicitous formation that family can take. The family as the place within society that produces a national populace has been undergoing some profound changes to its composition. The Canadian Charter of Rights and Freedoms has disallowed exclusively heterosexual constructs of the family to remain the only model of familial existence. The sexual redefinition of the conventional family by the inclusion of lesbians and gay men therefore has the ability to deconstruct our notions surrounding issues of gendered and sexually specified roles within the family.

description: [OIII] lambda 5007AA emission lines of 16 intracluster planetary nebulae candidates in the Coma cluster were detected with a Multi-Slit Imaging Spectroscopy (MSIS) technique using FOCAS on the Subaru telescope. The identification of these faint emission sources as PNe is supported by (i) their point-like flux distribution in both space and wavelength, with tight limits on the continuum flux; (ii) the identification of the second [OIII] lambda 4959 line in the only object at high enough velocity that this line too falls into the filter bandpass; (iii) emission line fluxes consistent with PNe at 100 Mpc distance, in the range 2.8 x 10^{-19} - 1.7 x 10^{-18} erg/s/cm^2; and (iv) a narrow velocity distribution approximately centered on the systemic velocity of the Coma cluster. Comparing with the velocities of galaxies in our field, we conclude that the great majority of these candidates would be intracluster PNe, free floating in the Coma cluster core. Their velocity dispersion is ~760 km/s, and their mean velocity is lower than that of the galaxies. The velocity distribution suggests that the intracluster stellar population has different dynamics from the galaxies in the Coma cluster core.

This compound is isotyp to the ferromagnetic systems RECu${}_9$Sn${}_4$ (RE = Ce, Pr, Nd) with Curie temperatures $T{}\rm_C$ = 5.5 K, 10.5 K and 15 K, respectively. UCu${}_9$Sn${}_4$ exhibits an uncommon magnetic behavior resulting in three different electronic phase transitions. Below 105 K the sample undergoes a valence transition accompanied by an entropy change of 0.5 Rln2. At 32 K a small hump in the specific heat and a flattening out in the susceptibility curve probably indicate the onset of helical spin order. To lower temperatures a second transition to antiferromagnetic ordering occurs which develops a small ferromagnetic contribution on lowering the temperature further. These results are strongly hinting for canted antiferromagnetism in UCu${}_9$Sn${}_4$.

description: Single-layer $\it{h}$-BN is known to have edges with unique magnetism, however, in the commonly fabricated multilayer $\text{AA}^{\prime}$-$\it{h}$-BN, edge relaxations occur that create interlayer bonds and eliminate the unpaired electrons at the edge. Recently, a robust method of growing the unconventional Bernal-stacked $\it{h}$-BN (AB-$\it{h}$-BN) has been reported. Here, we use theoretical approaches to investigate the nitrogen-terminated zigzag edges in AB-$\it{h}$-BN that can be formed in a controlled fashion using a high-energy electron beam. We find that these "open" edges remain intact in bilayer and multilayer AB-$\it{h}$-BN, enabling researchers potentially to investigate these edge states experimentally. We also investigate the thermodynamics of the spin configurations at the edge by constructing a lattice model that is based on parameters extracted from a set of first-principles calculations. We find that the edge spins in neighboring layers interact very weakly, resulting in a sequence of independent spin chains in multilayer samples. By solving this model using Monte Carlo simulations, we can determine nm-scale correlation lengths at liquid-N$_{2}$ temperatures and lower. At low temperatures, these edges may be utilized in magnetoresistance and spintronics applications.

description: We use scanning tunneling microscopy/spectroscopy (STM/S) to elucidate the atomically resolved electronic structure in strongly correlated topological kagome magnet Mn$_3$Sn. In stark contrast to its broad single-particle electronic structure, we observe a pronounced resonance with a Fano line shape at the Fermi level resembling the many-body Kondo resonance. We find that this resonance does not arise from the step edges or atomic impurities, but the intrinsic kagome lattice. Moreover, the resonance is robust against the perturbation of a vector magnetic field, but broadens substantially with increasing temperature, signaling strongly interacting physics. We show that this resonance can be understood as the result of geometrical frustration and strong correlation based on the kagome lattice Hubbard model. Our results point to the emergent many-body resonance behavior in a topological kagome magnet.

description: Although deep learning has achieved great success in image classification tasks, its performance is subject to the quantity and quality of training samples. For classification of polarimetric synthetic aperture radar (PolSAR) images, it is nearly impossible to annotate the images from visual interpretation. Therefore, it is urgent for remote sensing scientists to develop new techniques for PolSAR image classification under the condition of very few training samples. In this letter, we take the advantage of active learning and propose active ensemble deep learning (AEDL) for PolSAR image classification. We first show that only 35\% of the predicted labels of a deep learning model's snapshots near its convergence were exactly the same. The disagreement between snapshots is non-negligible. From the perspective of multiview learning, the snapshots together serve as a good committee to evaluate the importance of unlabeled instances. Using the snapshots committee to give out the informativeness of unlabeled data, the proposed AEDL achieved better performance on two real PolSAR images compared with standard active learning strategies. It achieved the same classification accuracy with only 86% and 55% of the training samples compared with breaking ties active learning and random selection for the Flevoland dataset.

description: We determine the cross-correlation function between galaxies and galaxy groups, using both the Two-Degree Field Galaxy Redshift Survey (2dFGRS) and the Sloan Digital Sky Survey (SDSS). We study the cross-correlation as a function of group mass, and as a function of the luminosity, stellar mass, colour, spectral type and specific star formation rate of the galaxies. All these cross-correlation functions show a clear transition from the `1-halo' to the `2-halo' regimes on a scale comparable to the virial radius of the groups in consideration. On scales larger than the virial radius, all cross-correlation functions are roughly parallel, consistent with the linear bias model. In particular, the large scale correlation amplitudes are higher for more massive groups, and for brighter and redder galaxies. In the `1-halo' regime, the cross-correlation function depends strongly on the definition of the group center. We consider both a luminosity-weighted center (LWC) and a center defined by the location of the brightest group galaxy (BGC). With the first definition, the bright early-type galaxies in massive groups are found to be more centrally concentrated than the fainter, late-type galaxies. Using the BGC, and excluding the brightest galaxy from the cross correlation analysis, we only find significant segregation in massive groups ($M \gta 10^{13}h^{-1}\msun$) for galaxies of different spectral types (or colours or specific star formation rates). In haloes with masses $\la 10^{13}h^{-1}\msun$, there is a significant deficit of bright satellite galaxies. Comparing the results from the 2dFGRS with those obtained from realistic mock samples, we find that the distribution of galaxies in groups is much less concentrated than dark matter haloes predicted by the current $Λ$CDM model.

Odd-Parity Spin-Triplet Superconductivity in Centrosymmetric Antiferromagnetic Metals

description: We propose a route to achieve odd-parity spin-triplet superconductivity in metallic collinear antiferromagnets with inversion symmetry. Owing to the existence of hidden antiunitary symmetry, which we call the effective time-reversal symmetry (eTRS), the Fermi surfaces of ordinary antiferromagnetic metals are generally spin-degenerate, and spin-singlet pairing is favored. However, by introducing a local inversion symmetry breaking perturbation that also breaks the eTRS, we can lift the degeneracy to obtain spin-polarized Fermi surfaces. In the weak-coupling limit, the spin-polarized Fermi surfaces constrain the electrons to form spin-triplet Cooper pairs with odd-parity. Interestingly, all the odd-parity superconducting ground states we obtained host nontrivial band topologies manifested as chiral topological superconductors, second-order topological superconductors, and nodal superconductors. We propose that layered double-perovskites with collinear antiferromagnetism, sandwiched by conventional superconductors, are promising candidate systems where our theoretical ideas can be applied to.
Long-Range Order of Vortex Lattices Pinned by Point Defects in Layered Superconductors

description: How the vortex lattice orders at long range in a layered superconductor with weak point pinning centers is studied through a duality analysis of the corresponding frustrated XY model. Vortex-glass order emerges out of the vortex liquid across a macroscopic number of weakly coupled layers in perpendicular magnetic field as the system cools down. Further, the naive magnetic-field scale determined by the Josephson coupling between adjacent layers is found to serve as an upperbound for the stability of any possible conventional vortex lattice phase at low temperature in the extreme type-II limit.

description: We give a brief and a critical review of the Barret-Crane spin foam models of quantum gravity. Then we describe two new spin foam models which are obtained by direct quantization of General Relativity and do not have some of the drawbacks of the Barret-Crane models. These are the model of spin foam invariants for the embedded spin networks in loop quantum gravity and the spin foam model based on the integration of the tetrads in the path integral for the Palatini action.

description: A set S of vertices in a graph G resolves G if every vertex is uniquely determined by its vector of distances to the vertices in S. The metric dimension of G is the minimum cardinality of a resolving set of G. This paper studies the metric dimension of cartesian products G*H. We prove that the metric dimension of G*G is tied in a strong sense to the minimum order of a so-called doubly resolving set in G. Using bounds on the order of doubly resolving sets, we establish bounds on G*H for many examples of G and H. One of our main results is a family of graphs G with bounded metric dimension for which the metric dimension of G*G is unbounded.

description: We discuss two models of opinion dynamics. First wepresent a brief review of the Hegselmann and Krause (HK) compromise model in two dimensions, showing that it is possible to simulate the dynamics in the limit of an infinite number of agents by solving numerically a rate equation for a continuum distribution of opinions. Then, we discuss the Opinion Changing Rate (OCR) model, which allows to study under which conditions a group of agents with a different natural tendency (rate) to change opinion can find the agreement. In the context of the this model, consensus is viewed as a synchronization process.
