Geographies of indebtedness : the spatial nature and lived experiences of household debt in Metro Vancouver
Creators: name: Hawes, Emily Jeanne
Publisher: name: University of British Columbia
Year: 2016

description: Since the 1990s, Canadian household debt levels have grown at an increasingly rapid rate, hitting records levels in late 2014. Mainstream representations paint the looming household debt crisis as a product of rampant overconsumption, underpinned by a societal lack of ‘financial literacy’. To what extent does the empirical evidence reflect such discourses? Few critical studies examine household debt in Canada, and still fewer consider the sub-national scale. According to existing scholarship, processes of financialization, securitization and neoliberalization influence household debt internationally and nationally. This thesis investigates the geography of high household debt levels at the local scale for Metro Vancouver. It examines the causes and consequences of heavy indebtedness in the everyday lived experiences of individual debtors, and the services and supports that they need to face these challenges. At the sub-CMA level, the spatial distribution of debt stress (debt-to-income and debt-to-wealth ratios) is assessed at the FSA level via a quantitative mapping analysis for Metro Vancouver – Canada’s most indebted city. Despite the generalized high debt stress across the CMA, a distinctly uneven spatial distribution of the costs, stresses (indebtedness) and benefits (gains in wealth) of rising mortgage and consumer debt levels emerges, with disproportionate stress in Vancouver’s outer suburbs. Through in-depth qualitative interviews with highly indebted Vancouverites, this thesis unpacks the everyday effects that increasing debt-loads have on residents of high-debt neighbourhoods. It draws on media discourse and debtor testimonies to consider the societal and survival pressures to engage in ever higher levels of borrowing experienced by financialized citizen subjects – funding consumption in a time of high income and wealth inequalities. Common causes of debt stress include unexpected life events such as divorce and job loss, easy accessibility of and marketing pressures to consume credit, and insufficient household resources as inflation surpasses wage growth. Financial literacy initiatives are called into question while, alongside issues of housing affordability, the study finds a critical need for lending regulations, non-predatory alternatives to small and short-term Payday loans, and reduced barriers to accessible and affordable mental health counseling for debtors.

description: This paper aims at identifying models of adulthood dominating in the discourse concerning care leavers. The conducted qualitative analysis of reports devoted to the process of gaining independence by care leavers from the period 2010-2020 indicates that the present institutional model of adulthood is not adequate to the social, cultural, and economic conditions in which transition to adulthood of contemporary young people occurs. It is also not conducive to the flexibility and multiplicity of life paths constructed by care leavers. Alternative models of adulthood implied in the conclusions and recommendations formulated in the analyzed reports evidence the need for an open discussion concerning the change of policies and practices as regards the organization and course of the process of gaining independence by care leavers.

Przeprowadzona jakościowa analiza treści raportów dotyczących procesu usamodzielnienia wychowanków instytucjonalnej pieczy zastępczej z lat 2010–2020 sugeruje, że obecny instytucjonalny model dorosłości nie jest adekwatny do warunków społeczno-kulturowych i ekonomicznych, w jakich przebiegają tranzycje w dorosłość współczesnych młodych ludzi, nie sprzyja wielości i elastyczności konstruowania ścieżek życiowych wychowanków. Alternatywne modele dorosłości występujące we wnioskach i rekomendacjach analizowanych raportów dowodzą potrzeby otwartej dyskusji nad zmianą polityk i praktyk w zakresie organizacji i przebiegu procesu usamodzielniania wychowanków instytucjonalnej pieczy zastępczej.

title: An apostrophe to Scots: the invention and diffusion of the Scots apostrophe in eighteenth-century Scottish verse
Creators: name: Selfe, David William
Publisher: name: University of Glasgow
Year: 2021

description: The intention of this thesis is to challenge three fundamental assumptions about the function of the ‘apologetic apostrophe’ – described henceforth as the ‘Scots apostrophe’ – which have, until now, exclusively characterised the scholarly understanding of this linguistic form in Scots literary history: 1. The function of apostrophised spelling forms in Scots is to indicate elision. 2. The use of apostrophised forms undermines perceptions of Scots as a language independent from English and is solely for the benefit of accessibility for an English readership. 3. Scots is intrinsically linked with Scottishness: as an agent of anglicisation, the use of apostrophised forms therefore contributes to the erosion of Scottish cultural identity. Situated within historical pragmatics – and combining corpus and philological analysis – this study investigates the origin and diffusion of the Scots apostrophe in eighteenth-century Scottish literary verse, with particular attention paid to the influential poetic miscellanies of James Watson, Allan Ramsay, Robert Burns, and Walter Scott. First and foremost, this thesis establishes a theoretical framework with which to understand the function of the Scots apostrophe in literary Scots that simultaneously contests unscholarly myth-making with regards to linguistic practices. In broader terms, the research therein demonstrates the value of non-lexical markers, like the apostrophe, as a capacious avenue for future historical pragmatic research.

description: The B^0_s differential production cross section is measured as functions of the transverse momentum and rapidity in pp collisions at sqrt(s) = 7 TeV, using the J/Psi phi decay, and compared with predictions based on perturbative QCD calculations at next-to-leading order. The data sample, collected by the CMS experiment at the LHC, corresponds to an integrated luminosity of 40 inverse picobarns. The B^0_s is reconstructed from the decays J/Psi to an oppositely charged muon pair and phi to K+ K-. The integrated B^0_s cross section times B^0_s to J/Psi phi branching fraction in the range 8 < pt(B) < 50 GeV/c and |y(b)| < 2.4 is measured to be 6.9 +/- 0.6 +/- 0.6 nb, where the first uncertainty is statistical and the second is systematic.

description: The social and political transformation that occurred in Poland following the fall of the communist system has resulted in an intensive development of non-governmental organizations, including those offering services for children and families. Social policy began to be perceived as a tool that allows for investing in the future of the youngest members of society (children and youth) rather than as a system of care services. Hence, the aim of this paper is to indicate threats and possibilities as regards the functioning of the foster care system and the process of adult care leavers’ gaining independence. A synthetic overview of formal changes that have occurred in Poland since 1982 in the range and forms of functioning of the mentioned institutions provides the basis for conclusions regarding the key problems. Based on this overview, the threats and possibilities of the contemporary foster care system are indicated, with particular attention paid to the process of care leavers’ as well as to determining directions for further changes of this system.
description: Przemiany społeczno-ustrojowe, które nastąpiły w Polsce po upadku systemu komunistycznego, zaowocowały intensywnym rozwojem organizacji pozarządowych, w tym świadczących usługi dla dzieci i rodzin. Polityka społeczna zaczęła być postrzegana jako narzędzie, które pozwala inwestować w przyszłość najmłodszych członków społeczeństwa (dzieci i młodzieży), a nie jako system usług opiekuńczych. Stąd celem niniejszego artykułu jest wskazanie zagrożeń i możliwości w zakresie funkcjonowania systemu pieczy zastępczej oraz procesu usamodzielniania się dorosłych wychowanków. Syntetyczny przegląd zmian formalnych, jakie zaszły w Polsce od 1982 roku w zakresie i formach funkcjonowania wymienionych instytucji, daje podstawę do wniosków dotyczących kluczowych problemów. Na tej podstawie wskazano na zagrożenia i możliwości współczesnego systemu pieczy zastępczej, ze szczególnym uwzględnieniem procesu wychodzenia z opieki oraz określenia kierunków dalszych zmian tego systemu.

Strategy abundance in evolutionary many-player games with multiple strategies

Year: 2011

description: Evolutionary game theory is an abstract and simple, but very powerful way to model evolutionary dynamics. Even complex biological phenomena can sometimes be abstracted to simple two-player games. But often, the interaction between several parties determines evolutionary success. Rather than pair-wise interactions, in this case we must take into account the interactions between many players, which are inherently more complicated than the usual two-player games, but can still yield simple results. In this manuscript we derive the composition of a many-player multiple strategy system in the mutation-selection equilibrium. This results in a simple expression which can be obtained by recursions using coalescence theory. This approach can be modified to suit a variety of contexts, e.g. to find the equilibrium frequencies of a finite number of alleles in a polymorphism or that of different strategies in a social dilemma in a cultural context.

Determination of small molecules in food matrices by molecularly imprinted polymers and surface enhanced Raman spectroscopy
Creators: name: Gao, Fang
Publisher: name: University of British Columbia
Year: 2016

description: The research work focuses on developing novel methods for determining small molecules in food matrices using molecularly imprinted polymers (MIPs) and surface enhanced Raman spectroscopy (SERS). MIPs are synthesized as artificial antibodies towards target molecules utilizing interactions between templates and functional monomers to impress complementary binding sites on polymers. MIPs selectively isolate templates from food extracts. SERS technique provides rapid and sensitive detection of MIPs-separated molecules. Statistical analysis including unsupervised principal component analysis (PCA), supervised simple linear regression and partial least square regression (PLSR) is employed to analyze SERS spectra. Chloramphenicol in milk and honey was determined using MIPs-packed solid phase extraction cartridge to isolate chloramphenicol from food matrices and dendritic silver to acquire SERS spectra of the eluted chloramphenicol. These spectra obtained from different spiked contents (0, 0.1, 0.5, 1, 5 ppm) of chloramphenicol in milk and honey were analyzed by PCA and PLSR (R > 0.9). MIPs particles were spread onto a thin layer chromatography (TLC) plate to determine Sudan I in paprika powder. Separation of Sudan I from paprika extract by an MIPs-TLC plate takes 30-40 s. SERS spectra obtained from Sudan I spot on the plate can be acquired within 1 s with gold colloid serving as SERS active substrate. A PLSR (R² = 0.978) model was constructed based on spiking levels (5, 10, 40, 70 and 100 ppm) of Sudan I in paprika powder. Histamine level in canned tuna was investigated using MIPs-polyvinyl chloride (PVC)-SERS method. MIPs-PVC films (recognition element) selectively extracted histamine from tuna extract. A gold colloid solution served as an eluting solvent to extract histamine from MIPs-PVC film and conducted a SERS detection of histamine. A PLSR model (R² = 0.947, RMSECV = 3.526) was built on SERS spectra of histamine with different spiking levels (3, 30 and 90 ppm) in canned tuna. The spectral results suggest the powerful separation of MIPs and sensitive detection of SERS. With statistical analysis, we have confirmed that SERS signals obtained by this MIPs-SERS approach rapidly and accurately quantify chloramphenicol in milk and honey, Sudan I in paprika powder and histamine in canned tuna.

description: We consider the finite temperature metal-insulator transition in the half filled paramagnetic Hubbard model on the infinite dimensional Bethe lattice. A new method for calculating the Dynamical Mean Field Theory fixpoint surface in the phase diagram is presented and shown to be free from the convergence problems of standard forward recursion. The fixpoint equation is then analyzed using dynamical systems methods. On the fixpoint surface the eigenspectra of its Jacobian is used to characterize the hysteresis boundaries of the first order transition line and its second order critical end point. The critical point is shown to be a cusp catastrophe in the parameter space, opening a pitchfork bifurcation along the first order transition line, while the hysteresis boundaries are shown to be saddle-node bifurcations of two merging fixpoints. Using Landau theory the properties of the critical end point is determined and related to the critical eigenmode of the Jacobian. Our findings provide new insights into basic properties of this intensively studied transition.

Nonthermal emission from the radio relic of the galaxy cluster A2256

description: We aim to obtain a consistent description of non-thermal emissions from Abell 2256 and to give a prediction for a gamma-ray emission from this galaxy cluster. Assuming that a radio relic illuminates a localization of an ongoing merger, and that both radio and non-thermal part of hard X-ray emission are due to electron component of cosmic rays filling the relic, we derived from radio and hard X-ray properties of the relic in A2256 the magnetic field strength and number densities for relativistic electrons and protons. Due to the interpretation of the radio relic as a structure formed just where a shock front is, we discuss a gamma-ray emission at the cluster periphery. The estimated strength of the magnetic field in the relic is equal to 0.05 \muG, while the amplitude of the electron number density varies from 3 x 10^{-4} to 3 x 10^{-5} cm^{-3} (respectively for the relic thickness of 50 to 500 kpc). We got a substantial degree of non-equipartition between cosmic rays and magnetic field in the relic region, where the CR pressure is approaching that of thermal gas. Our prediction for LOFAR is a synchrotron flux from the relic region of the order of \sim 6 Jy at 60MHz and \sim 10 Jy at 30MHz. The lower limit of the gamma-ray flux from the relic region calculated for a hadronic channel is of the order of 10^{-12} erg cm^{-2}.

description: Polarised Semi-Inclusive Deep Inelastic Scattering (SIDIS) processes allow to study Transverse Momentum Dependent partonic distributions (TMDs), which reveal a non trivial three dimensional internal structure of the hadrons in momentum space. One of the most representative of the TMDs is the so-called Sivers function that describes the distribution of unpolarized quarks inside a transversely polarized proton. We present a novel extraction of the Sivers distribution functions from the most recent experimental data of HERMES and COMPASS experiments. Using suitable parametrizations, within the TMD factorization scheme, and a simple fitting strategy, we also perform a preliminary exploration of the role of the proton sea quarks.

description: The presence of highly eccentric extrasolar planets in binary stellar systems suggests that the Kozai effect has played an important role in shaping their dynamical architectures. However, the formation of planets in inclined binary systems poses a considerable theoretical challenge, as orbital excitation due to the Kozai resonance implies destructive, high-velocity collisions among planetesimals. To resolve the apparent difficulties posed by Kozai resonance, we seek to identify the primary physical processes responsible for inhibiting the action of Kozai cycles in protoplanetary disks. Subsequently, we seek to understand how newly-formed planetary systems transition to their observed, Kozai-dominated dynamical states. We find that theoretical difficulties in planet formation arising from the presence of a distant companion star, posed by the Kozai effect and other secular perturbations, can be overcome by a proper account of gravitational interactions within the protoplanetary disk. In particular, fast apsidal recession induced by disk self-gravity tends to erase the Kozai effect, and ensure that the disk's unwarped, rigid structure is maintained. Subsequently, once a planetary system has formed, the Kozai effect can continue to be wiped out as a result of apsidal precession, arising from planet-planet interactions. However, if such a system undergoes a dynamical instability, its architecture may change in such a way that the Kozai effect becomes operative. The results presented here suggest that planetary formation in highly inclined binary systems is not stalled by perturbations, arising from the stellar companion. Consequently, planet formation in binary stars is probably no different from that around single stars on a qualitative level. Furthermore, it is likely that systems where the Kozai effect operates, underwent a transient phase of dynamical instability in the past.

description: The project Massive Unseen Companions to Hot Faint Underluminous Stars from SDSS (MUCHFUSS) aims at finding sdBs with compact companions like supermassive white dwarfs (M>1.0 Msun), neutron stars or black holes. The existence of such systems is predicted by binary evolution theory and recent discoveries indicate that they are likely to exist in our Galaxy. A determination of the orbital parameters is sufficient to put a lower limit on the companion mass by calculating the binary mass function. If this lower limit exceeds the Chandrasekhar mass and no sign of a companion is visible in the spectra, the existence of a massive compact companion is proven without the need for any additional assumptions. We identified about 1100 hot subdwarf stars from the SDSS by colour selection and visual inspection of their spectra. Stars with high velocities have been reobserved and individual SDSS spectra have been analysed. In total 127 radial velocity variable subdwarfs have been discovered. Binaries with high RV shifts and binaries with moderate shifts within short timespans have the highest probability of hosting massive compact companions. Atmospheric parameters of 69 hot subdwarfs in these binary systems have been determined by means of a quantitative spectral analysis. The atmospheric parameter distribution of the selected sample does not differ from previously studied samples of hot subdwarfs. The systems are considered the best candidates to search for massive compact companions by follow-up time resolved spectroscopy.

description: We are conducting a planet search survey with HARPS since seven years. The volume-limited stellar sample includes all F2 to M0 main-sequence stars within 57.5 pc, where extrasolar planetary signatures are systematically searched for with the radial-velocity technics. In this paper, we report the discovery of new substellar companions of seven main-sequence stars and one giant star, detected through multiple Doppler measurements with the instrument HARPS installed on the ESO 3.6m telescope, La Silla, Chile. These extrasolar planets orbit the stars HD 1690, HD 25171, HD 33473A, HD 89839, HD 113538, HD 167677 and HD 217686. The already-published giant planet around HD 72659 is also analysed here, and its elements are better determined by the addition of HARPS and Keck data. The other discoveries are giant planets in distant orbits, ranging from 0.3 to 29 MJup, in mass and between 0.7 and 10 years in orbital period. The low metallicity of most of these new planet-hosting stars reinforces the current trend for long-distance planets around metal-poor stars. Long-term radial-velocity surveys allow probing the outskirts of extrasolar planetary systems, although confidence in the solution may be low until more than one orbital period is fully covered by the observations. For many systems discussed in this paper, longer baselines are necessary to refine the radial-velocity fit and derive planetary parameters. The radial-velocity time series of stars BD -114672 and HIP 21934 are also analysed and their behaviour interpreted in terms of the activity cycle of the star, rather than long-period planetary companions.

description: We study a single-electron pulse injected into the chiral edge-state of a quantum Hall device and subject to a capacitive Coulomb interaction. We find that the scattered multi-particle state remains unentangled and hence can be created itself by a suitable classical voltage-pulse $V(t)$. The application of the inverse pulse $-V(-t)$ corrects for the shake-up due to the interaction and resurrects the original injected wave packet. We suggest an experiment with an asymmetric Mach-Zehnder interferometer where the application of such pulses manifests itself in an improved visibility.

description: We investigate the UV fixed-point structure of the three-dimensional Thirring model by means of the functional renormalization group (RG). We classify all possible 4-fermi interactions compatible with the present chiral and discrete symmetries and calculate the purely fermionic RG flow using a full basis of fermionic four-point functions in the point-like limit. Our results show that the UV complete (asymptotically safe) Thirring model lies in a two-dimensional coupling plane which reduces to the conventional Thirring coupling only in the strict large-Nf limit. In addition to the Thirring universality class which is characterized by one relevant direction (also at finite Nf), two further interacting fixed points occur which may define new universality classes of second-order phase transitions also involving parity-broken phases. The Nf-dependence of the Thirring fixed point sheds further light on the existence of an Nf-controlled quantum phase transition above which chiral symmetry remains unbroken for arbitrary large coupling, even though a definite answer will require a direct computation of competing orders.

description: This work is an extended version of a paper published last year in Physical Review Letters [S. de Man et al., Phys. Rev. Lett. 103, 040402 (2009)], where we presented measurements of the Casimir force between a gold coated sphere and a plate coated with either gold or an indium-tin-oxide (ITO) layer. The experiment, which was performed in air, showed that ITO is sufficiently conducting to prevent charge accumulation, but still transparent enough to halve the Casimir attraction when compared to gold. Here, we report all the experimental details that, due to the limited space available, were omitted in the previous article. We discuss the performance of our setup in terms of stability of the calibration procedure and reproducibility of the Casimir force measurement. We also introduce and demonstrate a new technique to obtain the spring constant of our force sensor. Furthermore, we present a thorough description of the experimental method, a comprehensive explanation of data elaboration and error analysis, and a complete characterization of the dielectric function and of the surface roughness of the samples used in the actual experiment.

description: Bioconversion of hemicelluloses into simpler sugars leads to production of a significant amount of pentose sugars, such as D-xylose. However, efficient utilization of pentoses by conventional yeast production strains remains challenging, especially due to inhibition by hexose co-fermentation. Wild yeast strains can provide new industrially relevant characteristics to bypass these inhibitions and efficiently utilize pentose sugars. To explore this strategy, we isolated gut-residing yeasts from the termite Macrotermes bellicosus collected in Comoé National Park, Côte d´Ivoire. The yeasts were classified through their ITS and LSU sequence and genomes of three new strains and species were sequenced and annotated. We identified a novel yeast species, which we name Barnettozyma botsteinii sp. nov. 1118T (MycoBank: 833563, CBS 16679T and IBT 710) and two new strains of Kurtzmaniella quercitrusa: var. comoensis (CBS 16678, IBT 709) and var. filamentosus (CBS 16680, IBT 711). The two K. quercitrusa strains grow 15% faster on synthetic glucose medium than Saccharomyces cerevisiae CEN.PKT in acidic conditions (pH = 3.2) and both strains grow on D-xylose as the sole carbon source at a rate of 0.35 h-1. At neutral pH, the yeast form of K. quercitrusa var. filamentosus, but not var. comoensis, switched to filamentous growth in a carbon source dependent manner, revealing phenotypic diversity among strains within the species. The utilisation of plant-derived sugars by K. quercitrusa indicates the potential for a mutualistic relationship between this yeast and the termite. Besides its metabolism, K. quercitrusa var. filamentosus also has a large potential as a production organism, because of its capacity to grow at low pH and to undergo a dimorphic shift.
Cold antihydrogen experiments and radial compression of antiproton clouds in the ALPHA apparatus at CERN
Creators: name: Gutierrez, Andrea
Publisher: name: University of British Columbia
Year: 2016

description: Antihydrogen is the simplest neutral antimatter atom. Precision comparisons between hydrogen and antihydrogen would provide stringent tests of CPT (charge conjugation/parity transformation/time reversal) invariance and the weak equivalence principle. In the last few years, the ALPHA collaboration has produced, and trapped antihydrogen. Most recently, this collaboration has probed antihydrogen’s internal structure by inducing hyperfine transitions in ground state atoms. In this thesis, many details of the cold antihydrogen formation, trapping and measurements of antihydrogen performed in the ALPHA apparatus are presented, with a focus on antiproton cloud compression. Such compression is an important tool for the formation and trapping of cold antihydrogen, since it allows control of the radial size and density of the antiproton cloud. Compression of non-neutral plasmas can be achieved using a rotating time-varying azimuthal electric field, which has been called rotating wall technique. In this work, we have observed a new mechanism for compression of a non-neutral plasma, specifically where antiprotons embedded in an electron plasma are compressed by a rotating wall drive at a frequency close to the sum of the axial bounce and rotation frequencies (in a frequency range of 50 – 750 kHz). The radius of the antiproton cloud is reduced by up to a factor of 20 with the smallest radius measured to be ∼ 0.2 mm. We have studied antiproton cloud compression as a function of the rotating wall frequency, the duration of compression, the rotating wall amplitude, the numbers of electrons and antiprotons, the magnetic field and the shape of the potential well. The frequency range over which compression is evident is compared to the sum of the antiproton bounce frequency and the system’s rotation frequency. It is suggested that bounce resonant transport is a likely explanation for the compression of antiproton clouds in this regime.

description: The issue of a Majorana, Dirac or pseudo-Dirac mass for gauginos must not be reduced to a question of an extension of the Minimal Supersymmetric Standard Model by extra states, parameters and phenomenological implications. On the contrary, it is intimately related to the fundamental issue of the realization of new symmetries in nature, R-symmetries. We present here a very dense compilation of the main features of models with (pseudo-)Dirac gauginos.

Computer vision

description: Deep neural networks have made significant advances in computer vision. However, several challenges limit their real-world applications. For example, domain shifts in vision data degrade model performance; visual appearance variances affect model robustness; it is also non-trivial to extend a model trained on one task to novel tasks; and in many applications, large-scale labeled data are not even available for learning powerful deep models from scratch. This research focuses on improving the transferability of deep features and the efficiency of deep vision model adaptation, leading to enhanced generalization and new capabilities on computer vision tasks. Specifically, we approach these problems from the following two directions: architectural adaptation and label-efficient transferable feature learning. From an architectural perspective, we investigate various schemes that permit network adaptation to be parametrized by multiple copies of sub-structures, distributions of parameter subspaces, or functions that infer parameters from data. We also explore how model adaptation can bring new capabilities, such as continuous and stochastic image modeling, fast transfer to new tasks, and dynamic computation allocation based on sample complexity. From the perspective of feature learning, we show how transferable features emerge from generative modeling with massive unlabeled or weakly labeled data. Such features enable both image generation under complex conditions and downstream applications like image recognition and segmentation. By combining both perspectives, we achieve improved performance on computer vision tasks with limited labeled data, enhanced transferability of deep features, and novel capabilities beyond standard deep learning models.

description: Spin correlations of top quarks produced in hadron collisions have not been observed experimentally with large significance. In this Letter, we propose a new variable that may enable demonstration of the existence of spin correlations with 3-4 sigma significance using just a few hundred dilepton events both at the Tevatron and the LHC. Such number of dilepton events has been observed at the Tevatron. At the LHC, it will become available once integrated luminosity of a few hundred inverse picobarns is collected.

description: Supersymmetric theories with gravitino dark matter generally do not allow the high reheating temperature required by thermal leptogenesis without running afoul of relic abundance or big bang nucleosynthesis constraints. We report on a successful search for parameter space that does satisfy these requirements. The main implication is the near degeneracy of the gluino with the other neutralinos in the spectrum. The leading discovery channel at the LHC for this scenario is through monojet plus missing energy events.

description: The implementation of the dynamics in Loop Quantum Gravity (LQG) is still an open problem. Here, we discuss a tentative dynamics for the simplest class of graphs in LQG: Two vertices linked with an arbitrary number of edges. We use the recently introduced U(N) framework in order to construct SU(2) invariant operators and define a global U(N) symmetry that will select the homogeneous/isotropic states. Finally, we propose a Hamiltonian operator invariant under area-preserving deformations of the boundary surface and we identify possible connections of this model with Loop Quantum Cosmology.

description: We find that a heavy gluon G of mass 800-900 GeV with small, mostly axial-vector couplings to the light quarks and relatively large vector and axial-vector couplings to the top quark can explain the t \bar{t} forward-backward asymmetry observed at the Tevatron with no conflict with other top-quark or dijet data. The key ingredient is a complete treatment of energy-dependent width effects and a new decay mode G->qQ, where q is a standard quark and Q a vector-like quark of mass 400--600 GeV. We show that this new decay channel makes the heavy gluon invisible in the t\bar{t} mass invariant distribution and discuss its implications at the Tevatron and the LHC.
