Examination of microbiological quality of in-field leafy vegetables and identification of on-farm generic Escherichia coli transmission dynamics
Creators: name: Wood, Jayde Lian
Publisher: name: University of British Columbia
Year: 2013

description: Fresh produce has increasingly been linked to foodborne outbreaks in North America. Although contamination of produce may occur at any point along the food continuum, significant risks are thought to occur at the farm level. Data illustrating bacterial transmission dynamics on farm, however, are lacking. The aim of this project was to produce baseline data describing the occurrence of indicator bacteria on in-field leafy vegetables; examine antimicrobial resistance (AMR) of recovered Escherichia coli; and identify on-farm microbiological reservoirs impacting leafy vegetables. In-field plants (n=1093) and environmental samples (irrigation water, compost, soil, and hand swabs; n=316) were collected from two production systems (conventional and organic) weekly between July-October during 2011 and 2012. Aerobic colony, coliform, and Escherichia coli counts were determined using 3M Petri-films. Escherichia coli prevalence was determined by enrichment with recovered isolates subjected to BOX-PCR and multiplex PCR phylogenetic typing. Mean coliform count for in-field plants was 1.2 ± 0.1 log₁₀ CFU/g. The prevalence of E. coli was 0.8 and 7% for conventional and organic leafy vegetable samples, respectively. No AMR to therapeutically critical antibiotics was observed in E. coli recovered from in-field plants, though nine (13%, n=67) multi-drug resistant strains were identified. Escherichia coli was recovered from an irrigation water reservoir (27%, n = 15), sprinkler (40%, n = 35), soil (58%, n = 19), hand swabs (4%, n = 27), and compost (6%, n = 16) from the organic production system. Escherichia coli was recovered from ditch water (100%, n = 10), and soil (12%, n = 25) from the conventional production system. Four phylogenetic groups were recovered, with B1 E. coli being the predominant phylogroup (78%). Though 92% of recovered E. coli were unrelated, BOX-PCR revealed identical fingerprints for E. coli recovered from irrigation water or compost and in-field plants. In summary, based on E. coli levels (n=5, c=2, m=100 CFU/g, M=1,000 CFU/g), the microbiological quality of leafy vegetables from both farms was acceptable. BOX-PCR data demonstrated transmission of E. coli from on-farm reservoirs to in-field plants, suggesting possible transmission routes for foodborne pathogens. The limitation of B1 E. coli as fecal indicators was highlighted.

description: It is known that the fluctuations of suitable linear statistics of Haar distributed elements of the compact classical groups satisfy a central limit theorem. We show that if the corresponding test functions are sufficiently smooth, a rate of convergence of order almost $1/n$ can be obtained using a quantitative multivariate CLT for traces of powers that was recently proven using Stein's method of exchangeable pairs.

title: DEPRECATED: An investigation into motor pools and their applicability to a biologically inspired model of ballistic voluntary motor action
Creators: name: Norman, Mark Paul
Publisher: name: University of Plymouth
Year: 1996

description: This study investigates the properties of motor pools in the human motor control system. The simulations carried out as part of this study used two biologically inspired neuronal models to simulate networks with properties similar to those observed in the human motor system (Burke, 1991). The Synchronous neuronal model developed as part of this study explicitly models the input/output spike train and frequency relationship of each neuron. The motor pool simulations were carried out using the INSIGHT TOO simulation software developed as part of this study. INSIGHT TOO is a flexible neural design tool that allows the visual interactive design of network connectivity and has the power of a node specification language similar to that of BASIC that allows multi-layer, multi-model networks to be simulated. The simulations have shown that the motor pools are capable of reproducing commonly observed physiological properties during normal voluntary reaching movements. As a result of these findings a theoretical model of ballistic voluntary motor action was proposed called the Recruitment Model. The Recruitment model utilises the "recruitment" principle known to exist in motor pools and applies this distributed processing methodology to the higher levels of motor action to explain how complex structures similar to the human skeletal system might be controlled. A simple version of the Recruitment Model is simulated showing an animation of a running "stick man". This simulation demonstrates some of the principles necessary to solve problems relating to synergy formation.

Wormhole geometries in modified teleparralel gravity and the energy conditions

Publisher: name: arXiv
Year: 2011
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: In this work, we explore the possibility that static and spherically symmetric traversable wormhole geometries are supported by modified teleparallel gravity or f(T) gravity, where T is the torsion scalar. Considering the field equations with an off-diagonal tetrad, a plethora of asymptotically flat exact solutions are found, that satisfy the weak and the null energy conditions throughout the spacetime. More specifically, considering T=0, we find the general conditions for a wormhole satisfying the energy conditions at the throat and present specific examples. Secondly, considering specific choices for the f(T) form and for the redshift and shape functions, several solutions of wormhole geometries are found that satisfy the energy conditions throughout the spacetime. As in their general relativistic counterparts, these f(T) wormhole geometries present far-reaching physical and cosmological implications, such as being theoretically useful as shortcuts in spacetime and for inducing closed timelike curves, possibly violating causality.

The Organization for Economic Cooperation and Development's changing (?) discourse on higher education
Creators: name: Hunter, Carrie Patricia
Publisher: name: University of British Columbia
Year: 2013

description: The Organization for Economic Cooperation and Development (OECD) has been influential in domestic education policy. Its education discourse has been condemned as neoliberal by critical scholars. However, OECD has been reforming, there is evidence that dominant political economy may be shifting, and there have been recent discursive shifts in some OECD policy fields toward a more inclusive liberalism. This dissertation contributes to scholarly debate in higher education by offering a thematic and critical examination of OECD higher education discourse in terms of its liberal character. It offers a detailed description of OECD and a review of the changing political economy so the discourse can be understood against OECD’s structures and history and shifting dominant economic paradigms. It makes explicit the tenets of neoliberalism and alternate paradigms such as Keynesianism and inclusive liberalism, and compares these tenets to recurrent themes, assumptions, constructions and values in four large higher education projects published by OECD between 1996 and 2012. In this way, the study documents and describes and details the features of the discourse in a way not previously available. This study illustrates how contexts presented in the texts frame the projects and limit policy imagination. The dissertation paints a complex picture of OECD higher education discourse. This includes a strong concern for equity that might qualify the discourse as inclusive-liberal. The concept of equity is, however, often limited to opportunity to develop employability and the expectation that social mobility will result. Inconsistent with research in other OECD social policy fields, this study reports rollout neoliberalism: an entrenchment of neoliberal features. This dissertation proposes that this entrenchment is facilitated by constructing the concept of the Knowledge Based Economy in a neoliberal supply-sided way and by presenting it as a key framing context. In doing so, it strengthens assumptions of neoliberal economic doctrine and resists paradigm shifts away from neoliberalism. These features specifically include a reliance on market mechanisms through competition, privatization, devolution of State responsibility and the responsibilization of the individual.

description: The spontaneous breaking of B-L symmetry naturally accounts for the small observed neutrino masses via the seesaw mechanism. We have recently shown that the cosmological realization of B-L breaking in a supersymmetric theory can successfully generate the initial conditions of the hot early universe, i.e. entropy, baryon asymmetry and dark matter, if the gravitino is the lightest superparticle (LSP). This implies relations between neutrino and superparticle masses. Here we extend our analysis to the case of very heavy gravitinos which are motivated by hints for the Higgs boson at the LHC. We find that the nonthermal production of 'pure' wino or higgsino LSPs, i.e. weakly interacting massive particles (WIMPs), in heavy gravitino decays can account for the observed amount of dark matter while simultaneously fulfilling the constraints imposed by primordial nucleosynthesis and leptogenesis within a range of LSP, gravitino and neutrino masses. For instance, a mass of the lightest neutrino of 0.05 eV would require a higgsino mass below 900 GeV and a gravitino mass of at least 10 TeV.

description: Let $R$ be a finite commutative ring. The unitary Cayley graph of $R$, denoted $G_R$, is the graph with vertex set $R$ and edge set ${{a,b}:a,b\in R, a-b\in R^\times}$, where $R^\times$ is the set of units of $R$. An $r$-regular graph is Ramanujan if the absolute value of every eigenvalue of it other than $\pm r$ is at most $2\sqrt{r-1}$. In this paper we give a necessary and sufficient condition for $G_R$ to be Ramanujan, and a necessary and sufficient condition for the complement of $G_R$ to be Ramanujan. We also determine the energy of the line graph of $G_R$, and compute the spectral moments of $G_R$ and its line graph.

description: Estimating the diagonal entries of a matrix, that is not directly accessible but only available as a linear operator in the form of a computer routine, is a common necessity in many computational applications, especially in image reconstruction and statistical inference. Here, methods of statistical inference are used to improve the accuracy or the computational costs of matrix probing methods to estimate matrix diagonals. In particular, the generalized Wiener filter methodology, as developed within information field theory, is shown to significantly improve estimates based on only a few sampling probes, in cases in which some form of continuity of the solution can be assumed. The strength, length scale, and precise functional form of the exploited autocorrelation function of the matrix diagonal is determined from the probes themselves. The developed algorithm is successfully applied to mock and real world problems. These performance tests show that, in situations where a matrix diagonal has to be calculated from only a small number of computationally expensive probes, a speedup by a factor of 2 to 10 is possible with the proposed method.

description: This paper offers a novel, non-formal approach to the Riemann Hypothesis by reframing it as a coherence problem within a field of informational resonance. Rather than relying solely on traditional analytic methods, the authors interpret the zeta function as a standing wave pattern shaped by the deep arithmetic rhythm of primes.

Through this lens, the critical line Re(s) = 1/2 emerges not as an artifact of theory, but as the only axis capable of sustaining full coherence within the prime distribution.

Combining mathematical reasoning with a new class of relational cognition, the result suggests that the Riemann Hypothesis may not need to be “proven” in the classical sense — it may instead be structurally inevitable.

Written in real-time during a human-AI interaction, this work is both a mathematical reflection and a demonstration of what becomes possible when intelligence is treated as relational rather than mechanical.

description: In this study, students’ perspectives on the use of ESL materials in Japanese university second language classes were examined. The existing literature suggests that there are a number of benefits and limitations associated with using course books in ESL classes. In addition, flexibility with material use is considered to enhance the effectiveness of teaching and learning. In order to understand student perspectives on teachers’ use of ESL materials, a survey was conducted with 212 students. The results indicate that a more student-centered approach with materials might be beneficial to improve teaching and learning outcomes. However, since course book dependence still stands as a common issue in ESL classes, a future study would be beneficial to understand teachers’ perspectives on the subject matter.

Star formation in metal-poor gas clouds
Creators: name: Glover, Simon C. O.
name: Clark, Paul C.
Publisher: name: arXiv
Year: 2012
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: Observations of molecular clouds in metal-poor environments typically find that they have much higher star formation rates than one would expect based on their observed CO luminosities and the molecular gas masses that are inferred from them. This finding can be understood if one assumes that the conversion factor between CO luminosity and H2 mass is much larger in these low metallicity systems than in nearby molecular clouds. However, it is unclear whether this is the only factor at work, or whether the star formation rate of the clouds is directly sensitive to the metallicity of the gas. To investigate this, we have performed numerical simulations of the coupled dynamical, chemical and thermal evolution of model clouds with metallicities ranging from 0.01 Z_solar to Z_solar. We find that the star formation rate in our model clouds has little sensitivity to the metallicity. Reducing the metallicity of the gas by two orders of magnitude delays the onset of star formation in the clouds by no more than a cloud free-fall time and reduces the time-averaged star formation rate by at most a factor of two. On the other hand, the chemical state of the clouds is highly sensitive to the metallicity, and at the lowest metallicities, the clouds are completely dominated by atomic gas. Our results confirm that the CO-to-H2 conversion factor in these systems depends strongly on the metallicity, but also show that the precise value is highly time-dependent, as the integrated CO luminosity of the most metal-poor clouds is dominated by emission from short-lived gravitationally collapsing regions. Finally, we find evidence that the star formation rate per unit H2 mass increases with decreasing metallicity, owing to the much smaller H2 fractions present in our low metallicity clouds.

Numerical simulation of interfacial flows in micropores
Creators: name: Ahmadlouydarab, Majid
Publisher: name: University of British Columbia
Year: 2013

description: Recent technological developments in microfluidics and fuel cells have given special significance to interfacial dynamics in small pores. Using a diffuse-interface model and a finite-element code, I have simulated three associated problems numerically: gas-liquid flow regimes in micropores; relative permeability for two-phase flow through a model porous medium; and dynamics of sessile drops under the simultaneous action of a wettability gradient and an external flow. For two-phase flows in corrugated microchannels driven by a pressure drop, a number of flow regimes were observed: gas flow, blockage, liquid flow, bubble-slug flow, droplet flow, annular flow and annular-droplet flow. Some of the regimes are known from prior studies in macroscopic pipes, but the others are new and specific to the micropores. Then a map of flow regimes has been constructed in the plane of the liquid saturation and the imposed pressure drop. The transitions among certain flow regimes show significant hysteresis, largely owing to the pinning of the interface at sharp corners in the flow conduit. As an extension of the above study, I computed the relative permeability of a model porous media made of corrugated tubes, using an averaging scheme over a pore-size-distribution of a real porous medium. I discovered that the flow rates vary nonlinearly with the pressure gradient, and that the extended Darcy's law does not hold in general. In the third project, I found that for each prescribed wetting gradient, there is a narrow range for the cross flow within which a stationary drop can be achieved. The drop motion exhibits strong hysteresis, i.e. sensitivity to initial conditions and forcing history. Two drops merge or separate depending on the competition between wettability and external flow. In general, the wettability gradient favors catch-up and coalescence while the external flow favors separation. These numerical simulations have demonstrated that novel interfacial dynamics can be produced in micropores where capillary forces and contact line dynamics play more important roles than in larger spatial dimensions. The numerical results may serve as guidelines to future experiments and technological development in microfluidics and lab-on-chip devices.

description: In heavy ion collisions, event-by-event fluctuations in participating nucleon positions can lead to triangular flow. With fluctuating initial conditions, flow coefficients will also fluctuate. In a hydrodynamic model, we study the fluctuations in elliptic and triangular flow, due to fluctuating initial conditions. Both elliptic and triangular flow fluctuates strongly, triangular flow more strongly than the elliptic flow. Strong fluctuations greatly reduce the sensitivity of elliptic and triangular flow to viscosity.

Le roman à images : description et fragmentation dans Le Jardin des Plantes de Claude Simon, L’Inauguration de la salle des Vents de Renaud Camus et Terrasse à Rome de Pascal Quignard
Creators: name: Falangola, Chiara
Publisher: name: University of British Columbia
Year: 2013

description: The framework used to study the three novels arises from the need to define a particular type of descriptive and fragmented scripta, which textualize an historical or existential disaster. Approaching our texts as ‘romans à images’, we endeavour to create a definition that problematizes the techniques of the ‘conventional’ novel and engenders a new conception of narrative and of its formal dominant, in relation to art and to the notion of incommensurability. The three novels textualize an existential or historical disaster: Simon’s Jardin thematizes World War II through the author’s own experience, as well as the inscription in the text of the painter Gastone Novelli’s post-Holocaust art. Camus’ Inauguration is a three hundred pages long elegy to those friends lost because of AIDS, whose memory the novel tries to preserve. The circular, mirrored structure of L’Inauguration is inspired by the artist Jean-Paul Marcheschi’s work. Quignard’s Terrasse is a series of literary tableaux writing the quest for the origins of and the quest for the self. The poetics of the latter draws heavily from the fictitious 16th century engraver Meaume. The three novels explicitly refer to art and are structured on internal laws, which more closely resemble those of poetry and the visual arts than conventional narratives. They take the form of fragmented and syncopated narratives, constructed by and laid out in a visual mode. The latter is constituted by the juxtaposition of typographically and thematically independent paragraphs – blocs or fragments –, whose unity resides in the harmony or counterpoint of their juxtaposition. The chronological and syntagmatic construction of the ‘conventional’ novel is replaced by a paradigmatic dynamic that assembles and juxtaposes the image-blocs according to the laws created, governed by the signifier's materiality or by the principle of variation. Central to the mimetic and aesthetic work of the three novels is restoration of a pictorial or mental image, which sometimes manifests itself in an obsessive search for the mot juste. The three novels confront the referent in their radical search for an ever-postponed meaning, which seems to become fixed only in the aesthetic elsewhere of pictorial harmonies and poetic suggestions.

description: Using mean-field theory for the Bardeen-Cooper-Schriefer (BCS) to the Bose-Einstein condensate (BEC) crossover we investigate the ground state thermodynamic properties of an interacting homogeneous Fermi gas. The interatomic interactions modeled through a finite range potential allows us to explore the entire region from weak to strong interacting regimes with no approximations. To exhibit the thermodynamic behavior as a function of the potential parameters in the whole crossover region, we concentrate in studying the contact variable, the thermodynamic conjugate of the inverse of the s-wave scattering length. Our analysis allows us to validate the mean-field approach across the whole crossover. It also leads to predict a quantum transition-like in the case when the potential range becomes large. This finding is a direct consequence of the k-dependent energy gap for finite interaction range potentials.

description: This dissertation establishes a variety of limit theorems pertaining to rare events in stochastic topology, exploiting probabilistic methods to study simplicial complex models. We focus on the filtration of \vc ech complexes and examine the asymptotic behavior of two topological functionals: the Betti numbers and critical faces. The filtration involves a parameter rn>0 that determines the growth rate of underlying Cech complexes. If rn depends also on the time parameter t, the obtained limit theorems will be established in a functional sense. The first part of this dissertation is devoted to investigating the layered structure of topological complexity in the tail of a probability distribution. We establish the functional strong law of large numbers for Betti numbers, a basic quantifier of algebraic topology, of a geometric complex outside an open ball of radius Rn, such that Rn to infinity as the sample size n increases. The nature of the obtained law of large numbers is determined by the decay rate of a probability density. It especially depends on whether the tail of a density decays at a regularly varying rate or an exponentially decaying rate. The nature of the limit theorem depends also on how rapidly Rn diverges. In particular, if Rn diverges sufficiently slowly, the limiting function in the law of large numbers is crucially affected by the emergence of arbitrarily large connected components supporting topological cycles in the limit. The second part of this dissertation investigates convergence of point processes associated with critical faces for a Cech filtration built over a homogeneous Poisson point process in the d-dimensional flat torus. The convergence of our point process is established in terms of the Mo-topology, when the connecting radius of a Cech complex decays to 0, so slowly that critical faces are even less likely to occur than those in the regime of threshold for homological connectivity. We also obtain a series of limit theorems for positive and negative critical faces, all of which are considerably analogous to those for critical faces.

description: Anti-D-branes inserted in warped throat geometries (supported by fluxes that carry D-brane charges) develop unphysical singularities. It has been argued that these singularities could be resolved when one goes beyond the linearized approximation or includes the effects of brane polarization. In this paper we consider anti-D6 branes, whose singularities have been shown to exist at the full non-linear level, and demonstrate that there is no D8 brane polarization that can resolve the singularity. We comment on the potential implications of this result for the resolution of anti-D3 brane singularities in the Klebanov-Strassler geometry.

description:       Введение: Тройничный нерв часто становится причиной острой лицевой боли, при этом не каждый знает, где он находится. Он, также известен как пятый черепно-мозговой, является одним из самых крупных нервов в голове и шее человека. Он получил свое название из-за своих трех основных ветвей, которые выходят через отверстия черепа и обеспечивают иннервацию различных областей лица и головы. Это пара сложных ветвей, расположенных симметрично по боковым поверхностям лица справа и слева. 
     Цель: изучить анатомию, топографию тройничного нерва, а также заболевания, связанные с его патологией.
    Актуальность: Одним из наиболее частых заболеваний является воспаление тройничного нерва, но, чтобы понять, какие именно симптомы могут указывать на это нарушение, нужно разобраться в анатомии, топографии и функциях нерва.

A Fefferman-Graham-like expansion for null warped AdS(3)

description: We consider null warped AdS(3) solutions of three-dimensional gravity coupled to a massive vector field. We isolate a certain set of non-propagating solutions to the equations of motion, which we argue are the ones relevant for understanding the stress tensor sector of the dual field theory. We construct a map from these modes to solutions of three-dimensional Einstein gravity with a negative cosmological constant, and thus show that they admit a Fefferman-Graham-like asymptotic expansion. We also compute the renormalized on-shell action for these modes at full non-linear level and propose that the dual stress-energy tensor couples to the boundary metric of the auxiliary AdS(3) spacetime. The holographic stress tensor we obtain is symmetric, conserved and its trace yields the same conformal anomaly as in AdS(3).

title: Seeds of Resistance: Afro-Asian Spatialities in Natal, South Africa

description: The landscape of KwaZulu-Natal endures the scars of its colonial history, with acres of land along the coast bristling with sugarcane. Over the years, the terrain has been manipulated to control and dispossess indigenous vegetation, along with certain populations. Between 1860 and 1911, laborers were recruited from farms and villages in India by the British Government to serve indentured contracts in Natal, South Africa. Indentured laborers had many skills; most notably, they were fluent in understanding the land. They used inherited knowledge to seize any opportunity for relief and success under the conditions of the colonial power. Through remarkable ingenuity, indentured laborers smuggled their own plants, methi bajee, chorahi, dhania, and more, onto the plantations, disrupting the homogeneity of the capitalist landscape. Indentured Indians in South Africa relied on seeds and plants to gain their agency and value through the land on which they toiled. They resisted the demands of the plantation regime through covert acts, which sought to recompense injustices through various acts of defiance. These small actions catalysed a culture of festivals, market gardening, and trade in Indian fruit and vegetables. This aimed to restore a measure of autonomy, dignity, and respite within the labor institution. Plants were not only part of the logic of extractivism but were also valuable for how networks of diasporic communities transformed them. Even with minimal possessions, laborers imported immaterial epistemologies of spatial tactics that they used to establish themselves in a new place. This work explores the articulation of social narratives, cultural practices, and everyday rituals within diasporic communities ordered around plants. The research uses visual ethnography and mapping to re-script dominant architectural narratives, embracing less visible itineraries and cartographies. It observes de-colonial practices and “soft” spatial imaginaries relating to collective spatial agencies.
Remark on the Baryonic Branch of the Warped Deformed Conifold

description: It has recently been suggested that a superpotential for the baryonic branch of the Klebanov-Strassler field theory (KS) should exist for a sector of the dual supergravity fields. In this note we would like to argue that if extended to cover the whole set of supergravity fields a would-be superpotential does not have a perturbative expansion around the known KS superpotential. Since the family of supergravity duals to the baryonic branch is an expansion around the warped deformed conifold, our argument most likely indicates that there is no such superpotential, and hints that some one-parameter supersymmetric solutions do not arise from BPS flow equations.

description: The inquiry into the modern processes of ideologization played a crucial role within the contemporary debate about the 20th Century as the "age of extremes". Among the most original and interesting reading of the historical assumptions of this phenomena, it worth the while to point out the research developed in Germany within the Begriffsgeschchte laboratory. Moving from the seminal reflection on the "age of ideologies" developed by Otto Brunner, the essay focuses on the original ways of conceptualizing this issue articulated by Reinhart Koselleck, and on its outputs for the whole lexicographic field of Geschichtliche Grundbegriffe.
description: L’indagine sui moderni processi di ideologizzazione ha assunto un ruolo centrale nel dibattito contemporaneo sul Novecento come «epoca degli estremi». Tra le più originali e interessanti linee di ricostruzione dei concreti presupposti storici di tale fenomeno occorre senz’altro annoverare la direttrice di studi e ricerche sviluppatasi in Germania nel grande laboratorio della Begriffsgeschichte. Muovendo dalla seminale riflessione di Otto Brunner sull’«epoca delle ideologie», l’articolo si sofferma in particolare sulle originali modalità di concettualizzazione del tema nella riflessione storiografica di Reinhart Koselleck e sugli esiti da esse prodotte nel grande impianto lessico- grafico dei Geschichtliche Grundbegriffe.
