description: Colon cancer is initiated from deregulation of Wnt/beta-catenin signaling in intestinal stem cells. BCL9 and Pygo proteins are essential co-activators that enhance Wnt target gene transcription in cancer cells. Recently, synthetic compounds have been characterized in vitro which interfere with the formation of the nuclear beta-catenin/BCL9/Pygo complex.

We have evaluated the role of BCL9/BCL9-2 and Pygo1/Pygo2 in intestinal tumorigenesis using genetic mouse models and human cancer cells. We show that our genetic mouse models are valuable to study in vivo the efficacy of novel compounds that inhibit the BCL9-2/Pygo2/ß-catenin interaction and function during tumor initiation and progression.

description: We present deep HST/ACS observations in g,r,i,z towards the z=4.1 radio galaxy TN J1338-1942 and its overdensity of >30 spectroscopically confirmed Lya emitters (LAEs). We select 66 g-band dropouts to z=27, 6 of which are also a LAE. Although our color-color selection results in a relatively broad redshift range centered on z=4.1, the field of TN J1338-1942 is richer than the average field at the >5 sigma significance, based on a comparison with GOODS. The angular distribution is filamentary with about half of the objects clustered near the radio galaxy, and a small, excess signal (2 sigma) in the projected pair counts at separations of <10" is interpreted as being due to physical pairs. The LAEs are young (a few x 10^7 yr), small ( = 0.13") galaxies, and we derive a mean stellar mass of ~10^8-9 Msun based on a stacked K-band image. We determine star formation rates, sizes, morphologies, and color-magnitude relations of the g-dropouts and find no evidence for a difference between galaxies near TN J1338-1942 and in the field. We conclude that environmental trends as observed in clusters at much lower redshift are either not yet present, or are washed out by the relatively broad selection in redshift. The large galaxy overdensity, its corresponding mass overdensity and the sub-clustering at the approximate redshift of TN J1338-1942 suggest the assemblage of a >10^14 Msun structure, confirming that it is possible to find and study cluster progenitors in the linear regime at z>4.

description: This report has been prepared to describe the history and present condition of a landslide area on Interstate Route I-75 in Covington, Kentucky, This landslide is one of several to be studied as part of a research project on the "Development of a Practical Method of Locating and Tracing Seepage Water in Unstable Slopes. " On April 10, 1963, a request was submitted to the Bureau of Public Roads to change the Work Program HPS-1(24) to include this research project. Approval was received on May 2, 1963. Work done on this research project prior to May 2 was at Department of Highway expense with work accomplished since being done on a participating basis.  An attempt will be made to give the history of earth movement at this particular site and to describe the condition of the area at the present time. This discussion will be presented in chronological order using photographs and sketches to illustrate the situation.  A site plan of the general area of earth movement is shown in Figure 1. The details shown in black in this figure represent features that were being constructed or had been constructed at the time the first earth movement was noted.  Plans are being made to attempt to locate and trace the paths of water that may be contributing factors in this landslide movement. Various techniques are being given serious consideration for this purpose and include the use of fluorescent dyes, radioactive tracers and the electrical resistivity apparatus.

description: The maximum achievable performance of strange-jet tagging at hadron colliders and the loss in performance in different detector designs is estimated based on simulated truth jets from strange-quark and down-quark hadronisation. Both jet types are classified with a recurrent neural network using long short-term memory units, at first using all available truth particles and then applying selections to study the impacts of ideal tracking detectors, Cherenkov detectors, and calorimeters. Additionally, a manual reconstruction of strange hadron decays such as $K_S\rightarrow π^+ π^-$ from charged tracks is considered.

description: We study a two-species cross-diffusion model that is inspired by a system of convection-diffusion equations derived from an agent-based model on a two-dimensional discrete lattice. The latter model has been proposed to simulate gang territorial development through the use of graffiti markings. We find two energy functionals for the system that allow us to prove a weak-stability result and identify equilibrium solutions. We show that under the natural definition of weak solutions, obtained from the weak-stability result, the system does not allow segregated solutions. Moreover, we present a result on the long-term behavior of solutions in the case when the product of the masses of the densities are smaller than a critical value. This result is complemented with numerical experiments.

But I’m not an artist : beginning elementary generalist teachers constructing art teaching practices from beliefs about ability to create art
Creators: name: McCoubrey, L. Sharon
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this research was to investigate the past art experiences and the beliefs about ability to create art as held by beginning elementary generalist teachers, and the effects of those beliefs on art teaching. Constructivism as a learning theory formed the theoretical framework for this study. An investigation of the related literature explored the topics of ability to create art, elementary generalist teachers of art, beginning teachers, teachers' beliefs, preparation of art teachers, and beginning teachers' images of self as art teacher. The research, consisting of two phases, was conducted using a descriptive case study methodology. Phase one of the study consisted of using semi-structured interviews with eight elementary generalist teachers in order to determine their past art experiences and their beliefs about their ability to create art. Three of those participants formed the purposeful sample for phase two of the study which consisted of observations of five art lessons per participant, along with pre and post interviews. An extended final interview was conducted along with documentation examination and interviews with school personnel. The thesis which emerged from this study is that beliefs about ability to create art were formed from prior experiences with art, and that beliefs about an ability to create art affected the art teaching practice of the participants. The participants believed that they do not have an ability to create art and do not have the natural talent required to be an artist. These beliefs, along with their limited background in art, lack of subject matter knowledge in art, and their status as beginning teachers adversely affected their art teaching practice. This study revealed eight specific connections between beginning teachers' beliefs about their ability to create art and their art teaching practice. Insights into these beliefs about art making and their connections to art teaching suggest important implications. Noteworthy among these implications are the need for teacher education programs to provide for personal art making skill development and the need for schools to provide support and accountability within art education for beginning teachers.

The Schrodinger functional with chirally rotated boundary conditions
Creators: name: Sint, Stefan
Publisher: name: arXiv
Year: 2005
Subjects: subject: High Energy Physics - Lattice (hep-lat)
subject: FOS: Physical sciences

description: Using orbifold techniques I construct the Schrodinger functional (SF) for a doublet of Wilson quarks with chirally rotated boundary conditions. This allows to perform checks of universality: for instance, the renormalized SF coupling constant, defined with either boundary conditions, must have a unique continuum limit. Similarly, SF correlation functions in twisted mass QCD and standard QCD can be defined such that they share a common continuum limit. An additional benefit of the new set-up consists in the observation that all the bulk O(a) counterterms to the action and composite operators become irrelevant in the chiral limit. This implies that (ratios of) SF renormalization constants can be automatically O(a) improved, up to the effect of unavoidable boundary counterterms. As a first application we calculate the running coupling for Nf=2 flavours in the SF-scheme to one-loop order of perturbation theory. Universality of the continuum limit is confirmed and the irrelevance of the Sheikholeslami-Wohlert term in the action is demonstrated explicitly

description: In moderately strong magnetic fields, the difference in Lande g-factors in each of the dots of a coupled double quantum dot device may induce oscillations between singlet and triplet states of the entangled electron pair and lead to a nonequilibrium electron spin polarization. We will show that this polarization may partially survive the rapid inhomogeneous decoherence due to random nuclear magnetic fields.

Color-Dipole Picture versus Hard Pomeron in Deep Inelastic Scattering

Publisher: name: arXiv
Year: 2020
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: For photon virtualities of $Q^2 \gsim 20 {\rm GeV}^2$, the results of the (hard Pomeron) fit in the tensor-Pomeron model in terms of the variables $Q^2$ and the virtual-photon-proton energy squared, $W^2$, provide empirical evidence for the validity of the Color Dipole Picture (CDP). Consistency of the CDP with the perturbative QCD (pQCD) improved parton model implies the prediction of $C_2 = ε_0 \cong 0.30$ for the exponent $C_2$ of the energy-squared dependence in agreement with the results of the fits. For $Q^2 \lsim 20 GeV^2$, the CDP yields a parameter-free smooth transition from $Q^2 \gsim 20 {\rm GeV}^2$ to $Q^2 = 0$ photoproduction, in distinction from the tensor-Pomeron model that relies on the additional parameter quantifying the intercept of the soft-Pomeron trajectory.

Below a temperature T_q ~ 80K, the local electric field gradient (EFG) and the absolute intensity of the NMR signal of the planar O site exhibit a dramatic decrease. We interpret these results as microscopic evidence for a spatially inhomogeneous charge distribution, where the NMR signal from O sites in the domain walls of the spin density modulation are wiped out due to large hyperfine fields, and the remaining signal arises from the intervening Mott insulating regions.

description: This study examined the characteristics and views of farmers market consumers in Alabama using data generated from 222 consumers randomly selected from two farmers markets. The survey was designed to solicit relevant information necessary to facilitate the study and to provide information on socioeconomic and demographic characteristics of the clients. Data were summarized and tabulated using descriptive statistics. Results show that when buying fruits and vegetables, consumers are interested in freshness, appearance, variety and selection of produce, availability of locally grown items, price and atmosphere of the store. These results are consistent with the results using the general state sample.

description: The software tool GRworkbench is an ongoing project in visual, numerical General Relativity at The Australian National University. Recently, GRworkbench has been significantly extended to facilitate numerical experimentation in analytically-defined space-times. The numerical differential geometric engine has been rewritten using functional programming techniques, enabling objects which are normally defined as functions in the formalism of differential geometry and General Relativity to be directly represented as function variables in the C++ code of GRworkbench. The new functional differential geometric engine allows for more accurate and efficient visualisation of objects in space-times and makes new, efficient computational techniques available. Motivated by the desire to investigate a recent scientific claim using GRworkbench, new tools for numerical experimentation have been implemented, allowing for the simulation of complex physical situations.

description: A recent take towards Federated Analytics (FA), which allows analytical insights of distributed datasets, reuses the Federated Learning (FL) infrastructure to evaluate the summary of model performances across the training devices. However, the current realization of FL adopts single server-multiple client architecture with limited scope for FA, which often results in learning models with poor generalization, i.e., an ability to handle new/unseen data, for real-world applications. Moreover, a hierarchical FL structure with distributed computing platforms demonstrates incoherent model performances at different aggregation levels. Therefore, we need to design a robust learning mechanism than the FL that (i) unleashes a viable infrastructure for FA and (ii) trains learning models with better generalization capability. In this work, we adopt the novel democratized learning (Dem-AI) principles and designs to meet these objectives. Firstly, we show the hierarchical learning structure of the proposed edge-assisted democratized learning mechanism, namely Edge-DemLearn, as a practical framework to empower generalization capability in support of FA. Secondly, we validate Edge-DemLearn as a flexible model training mechanism to build a distributed control and aggregation methodology in regions by leveraging the distributed computing infrastructure. The distributed edge computing servers construct regional models, minimize the communication loads, and ensure distributed data analytic application's scalability. To that end, we adhere to a near-optimal two-sided many-to-one matching approach to handle the combinatorial constraints in Edge-DemLearn and solve it for fast knowledge acquisition with optimization of resource allocation and associations between multiple servers and devices. Extensive simulation results on real datasets demonstrate the effectiveness of the proposed methods.

description: This paper reports on initial data collection for the consumer-preference objective in the three-year research project, "An Extended-Season Barry Production and Marketing System to Enhance Viability of Small Appalachian Farms and Rural Communities." This USDA NRI-funded project studies impacts on small farms and rural communities of widespread adoption of a unique full-season system of berry production with sales to high-value markets. Small-acreage farms in Southern Ohio and similar Appalachian regions are looking for alternatives that may approach the per-acre returns of traditional tobacco production. Small fruit crops have similar production requirements (labor and management intensive, small acreage) and can provide a significant income that more closely approaches tobacco than do many other alternatives. The overall project combines research on the required production system, on marketing strategies for high-value berries and berry products produced in this region, and on the impact such production and processing may have on case-study communities. This report relates to work to understand attributes consumers value in the market that may inform producers on marketing strategies.

We consider ALE-fibered $G_2$-manifolds and study the 4d physics from the view point of a partially twisted 7d supersymmetric Yang-Mills theory and its Higgs bundle. Euclidean M2-brane instantons descend to non-perturbative effects of the 7d supersymmetric Yang-Mills theory, which are found to be in one to one correspondence with the instantons of a colored supersymmetric quantum mechanics. We compute the contributions of M2-brane instantons to the 4d superpotential in the effective 7d description via localization in the colored quantum mechanics. Further we consider non-split Higgs bundles and analyze their 4d spectrum.

The nanotubes are synthesized by chemical vapor deposition directly on a metal surface. The high temperature ~800 C involved in the growth process poses challenging issues such as surface roughness and integrity of the structure which are addressed in this work. We demonstrate the effectiveness of the gate on the freestanding part of the nanotubes by performing tunneling spectroscopy that reveals Coulomb blockade diamonds. Our approach enables combined scanning tunneling microscopy and gated electron transport investigations of carbon nanotubes.

description: For manifolds $\cal M$ of noncompact type endowed with an affine connection (for example, the Levi-Civita connection) and a closed 2-form (magnetic field) we define a Hilbert algebra structure in the space $L^2(T^*\cal M)$ and construct an irreducible representation of this algebra in $L^2(\cal M)$. This algebra is automatically extended to polynomial in momenta functions and distributions. Under some natural conditions this algebra is unique. The non-commutative product over $T^*\cal M$ is given by an explicit integral formula. This product is exact (not formal) and is expressed in invariant geometrical terms. Our analysis reveals this product has a front, which is described in terms of geodesic triangles in $\cal M$. The quantization of $δ$-functions induces a family of symplectic reflections in $T^*\cal M$ and generates a magneto-geodesic connection $Γ$ on $T^*\cal M$. This symplectic connection entangles, on the phase space level, the original affine structure on $\cal M$ and the magnetic field. In the classical approximation, the $\hbar^2$-part of the quantum product contains the Ricci curvature of $Γ$ and a magneto-geodesic coupling tensor.

The information derived from this study is useful for lamb processors and producers in Australia and New Zealand who wish to anticipate future market changes and derived demands for their products in the United States.
Discovering and constituting meanings and identities midst languages and cultures
Creators: name: Armstrong, John Marshall
Publisher: name: University of British Columbia
Year: 2009

description: How should we understand the lived experiences of students in an English language program at a community college? This study seeks to explore and discuss the experiences of international students as they discover and constitute cultural identities in places between languages and cultures. It suggests a link between the vibrancy of these lived experiences and an English language education program which understands the value of the lived curriculum. The text includes the narratives of three international students and the interpreting of those conversations by the researcher. Also participating in the study are the voices of teachers and the voices of writers of theory, with the researcher working in the middle, experiencing at the same time a discovering and constituting of his own cultural identity. Building on the work of postcolonial scholars of cultural theory and anthropology, the study suggests a different kind of inter-national classroom and community, one which has implications for teachers as inter-national educators. In doing so, the thesis attempts to respond to "calls for attention to international dimensions of curriculum study" (Pinar 1995) and suggests an approach to creating a different kind of theoretical and conceptual frame for language education. It is hoped that the research will open doors to new questions and avenues of study and will help in furthering our understanding of curriculum.

description: Some key elements in drought relief policy are outlined and the major themes in associated lobbying are discussed. Recent policy changes announced in 1992 are described in detail against the background of the Report of the Drought Policy Review Task Force (1990). Indifference curve analysis is used to compare recent developments with the preceding policies and the targeting problems associated with both policy regimes are discussed. It is found that the new drought relief policy is unsatisfactory in a number of ways. Discussion of the welfare implications of recent changes in drought policy is then provided and conclusions are finally drawn.

description: In this paper the sanitary measures for the meat trade in Pacific Rim countries are assessed from the perspective of the current GATT negotiations on sanitary and phytosanitary (SPS) measures. These negotiations include harmonisation of standards, greater transparency of domestic technical regulations, better risk assessment, promoting area freedom and improved dispute settlement procedures. It is concluded that greater coordination of SPS measures can overcome the potential misuse of some domestic policy sanitary instruments that impede international agricultural trade.

description: We consider the analyzing power on a spin-0 nuclear target. This observable is related to the imaginary part of the two-photon-exchange (box) diagram. We consider the contributions of elastic and inelastic intermediate states. The former requires knowledge of the elastic nuclear form factor, while the latter uses the optical theorem as input. The elastic contribution scales as the nuclear charge $Z$, while the inelastic contribution as the ratio of the atomic number and nuclear charge, $A/Z$. We provide estimates for $^4$He and $^{208}$Pb, in the kinematics of existing or upcoming experiments. In both cases, we predict negative values of a few parts per million, and the dominant contribution is due to inelastic contributions. The analyzing power can contribute a substantial systematic error in parity-violating experiments.

Risk and Uncertainty

description: Single-index models from portfolio theory have previously been adapted for risk efficient farm planning in North America. The potential for using single-index models in farm planning is considered in this paper both theoretically and in the light of two illustrative Australian case studies. It is concluded that single-index models have no significant computational or other advantages over full quadratic programming portfolio selection models for farm planning and may produce relatively poor plans and poor assessments of the risks associated with those plans.

description: We report on the stellar content, half-light radii and star formation rates of a sample of 10 known high-redshift ($z\gtrsim 2$) galaxies selected on strong neutral hydrogen (HI) absorption (log(N(HI)/cm$^{-2})>19$) toward background quasars. We use observations from the {\it Hubble Space Telescope} (HST) Wide Field Camera 3 in three broad-band filters to study the spectral energy distribution(SED) of the galaxies. Using careful quasar point spread function subtraction, we study their galactic environments, and perform the first systematic morphological characterisation of such absorption-selected galaxies at high redshifts. Our analysis reveals complex, irregular hosts with multiple star-forming clumps. At a spatial sampling of 0.067 arcsec per pixel (corresponding to 0.55 kpc at the median redshift of our sample), 40% of our sample requires multiple Sérsic components for an accurate modelling of the observed light distributions. Placed on the mass-size relation and the `main sequence' of star-forming galaxies, we find that absorption-selected galaxies at high redshift extend known relations determined from deep luminosity-selected surveys to an order of magnitude lower stellar mass, with objects primarily composed of star-forming, late-type galaxies. We measure half-light radii in the range $r_{1/2} \sim$ 0.4 to 2.6 kpc based on the reddest band (F160W) to trace the oldest stellar populations, and stellar masses in the range $\log (\mathrm{M}_{\star}/\mathrm{M}_{\odot}) \sim$ 8 to 10 derived from fits to the broad-band SED. Spectroscopic and SED-based star formation rates are broadly consistent, and lie in the range log(SFR/M$_{\odot} $yr$^{-1}$) $\sim$0.0 to 1.7.

description: We discuss the two- and three-point correlators in the two-dimensional three-state Potts model in the high-temperature phase of the model. By using the form factor approach and perturbed conformal field theory methods we are able to describe both the large distance and the short distance behaviours of the correlators. We compare our predictions with a set of high precision Monte-Carlo simulations (performed on the triangular lattice realization of the model) finding a complete agreement in both regimes. In particular we use the two-point correlators to fix the various non-universal constants involved in the comparison (whose determination is one of the results of our analysis) and then use these constants to compare numerical results and theoretical predictions for the three-point correlator with no free parameter. Our results can be used to shed some light on the behaviour of the three-quark correlator in the confining phase of the (2+1)-dimensional SU(3) lattice gauge theory which is related by dimensional reduction to the three-spin correlator in the high-temperature phase of the three-state Potts model. The picture which emerges is that of a smooth crossover between a Δtype law at short distances and a Y type law at large distances.

description: As a signatory of the General Agreement on Tariffs and Trade (GATT), Australia is permitted to impose duties on goods that have been imported below 'normal value' and have caused or threatened to cause 'material injury' to the domestic industry producing 'like goods'. There has been a recent push from various industries to increase protection for producers who have been injured by such practices. The Government is concerned, however, that harsher anti-dumping regulations will damage its position in the Uruguay Round of the GATT negotiations. As a result, a Senate Inquiry was established in 1990 to review Australia's anti-dumping legislation. The objective of this paper is to examine the effectiveness of the public policy process in addressing this issue. The analysis indicates that the process of devising new anti-dumping laws has failed to produce any significant improvements. A number of suggestions are made to make the policy more efficient and the process more effective.

description: Underground conduits have been used for hundreds of years for drainage and water supply purposes. With the advent of railway and auto-mobile transportation, the use of underground conduits for drainage purposes beneath the roadways increased greatly. It soon became apparent that there was a definite need for knowledge concerning the manufacture, installation, and field behavior of pipe culverts. Accordingly, in the first half of the century, much attention and research has been directed toward the development and establishment of acceptable techniques and specifications fot the manufacture and installation of pipe culverts. This work has been accomplished by many individuals and organizations.
S. Pearce’s model for studying objects and its application to a baptismal cross

description: This paper applies S. Pearce’s model for studying objects to a family heirloom, a baptismal cross. This model is a mnemonic device, not a system of inviolable rules. Furthermore, it is shown that the interpretative process needs to encompass not only information about the object, but also a new perception of the range of philosophical and technical concepts that shape the interpretation of material culture. It is also necessary to stress the understanding and applying the theory of the model for studying objects, realising the degree to which discussing objects contributes to and illuminates different aspects of material culture, given that learning is influenced by personal elements, too, as demonstrated by contemporary museum studies and studies of material culture.
