Chops studies - a modeling and simulation perspective
Creators: name: Sun, Jian
Publisher: name: Graduate Studies
Year: 2012
Subjects: subject: Engineering--Petroleum
subject: CHOPS

description: CHOPS refers to Cold Heavy Oil Production with Sand in Western Canada, with heavy oil and sand produced together. Being different from conventional primary recovery, wormhole propagation and foamy oil flow are observed to make CHOPS achieve considerable production. Differences between the conventional primary depletion and cold heavy oil production are discussed in terms of their drainage mechanisms, model formulation and modeling approaches. The goal of this study is to investigate the modeling techniques on wormhole propagation and foamy oil flow as well as their effects in simulation. This study demonstrates two kinds of wormhole modeling approaches: Modeling wormholes as high permeability channels resulting from the experimental observations in which new variables are set up to model the enhanced permeability channels and modeling wormholes as well segments resulting from the extension of wormholes that build more flow paths like wells. Also, a reaction - based pseudo bubble point model is applied in the modeling of foamy oil flow. The heavy oil solution gas drive is divided into several stages in order to capture the transfers between various gas partitions. The above different modeling approaches are implemented into a General Purpose Research Simulator. Numerical studies are conducted for pressure profiles, sand production characteristics in wormhole propagation, Gas-Oil Ratios (GOR) and Recovery Factors (RF) for foamy oil flow. The simulation results show the rationality of the proposed wormhole modeling approaches and indicate that pressure decline and a permeability increase rate are two main factors influencing CHOPS performance.

figure-ground segmentation

description: While multiple studies investigate the properties of the earliest and final stages of visual information processing, the underlying transformations leading from simple edge detection to object recognition remain seemingly intractable. To tackle this problem, we take a step back and ask what mechanisms could lead to a successful figure-ground segmentation of a given image. We propose the following conceptual framework: (i) alternating steps of feature detection and feature pooling (grouping) in a hierarchical manner; (ii) segmentation into (provisional) objects by an unsupervised learning procedure using the computed feature grouping strengths. We present an initial implementation of this model where grouping principles such as proximity or good continuation are leveraged to discover grouped objects in an image. Model simulations reveal a promising performance on classical Gestalt displays of dot lattices, contour integration, and texture segregation.

Subjects: subject: Probability (math.PR)

description: We give recurrence and transience criteria for two cases of time-homogeneous Markov chains on the real line with transition kernel $p(x,dy)=f_x(y-x)dy$, where $f_x(y)$ are probability densities of symmetric distributions and, for large $|y|$, have a power-law decay with exponent $α(x)+1$, with $α(x)\in(0,2)$. If $f_x(y)$ is the density of a symmetric $α$-stable distribution for negative $x$ and the density of a symmetric $β$-stable distribution for non-negative $x$, where $α,β\in(0,2)$, then the chain is recurrent if and only if $α+β\geq2.$ If the function $x\longmapsto f_x$ is periodic and if the set $\{x:α(x)=α_0:=\inf_{x\in\R}α(x)\}$ has positive Lebesgue measure, then, under a uniformity condition on the densities $f_x(y)$ and some mild technical conditions, the chain is recurrent if and only if $α_0\geq1.$

description: We study pattern formation inmagnetic compounds near the helimagnetic/ferromagnetic transition point in case of Dirichlet boundary conditions on the spin field. The energy functional is a continuum approximation of a J1 − J3 model and was recently derived in Cicalese et al. (SIAM J Math Anal 51: 4848–4893, 2019). It contains two parameters, one measuring the incompatibility of the boundary conditions and the other measuring the cost of changes between different chiralities.We prove the scaling law of the minimal energy in terms of these two parameters. The constructions from the upper bound indicate that in some regimes branching-type patterns form close to the boundary of the sample.

description: Topoisomerase II (topo II) is a ubiquitous enzyme required for the maintenance of DNA topology. Due to its essential nature, many pharmaceuticals have been found to or developed to target the enzyme for both laboratory and clinical uses. Topo II poisons, such as doxorubicin and etoposide, are commonly used in cancer chemotherapy regimens and are cytotoxic due to their ability to covalently trap topo II on cleaved DNA, leading to the accumulation of DNA double-stranded breaks. In contrast, compounds that inhibit topo II catalytic activity without generating DNA double-stranded breaks are classified as catalytic inhibitors and impair enzyme function at a number of stages in the catalytic cycle, including DNA binding, DNA cleavage, ATP hydrolysis, and enzyme dissociation. Some catalytic inhibitors have been found to counter the DNA damaging effects of topo II poisons. This thesis describes work identifying salicylate as a novel catalytic inhibitor of topo II. It demonstrates that pretreatment of cells with salicylate, prior to treatment with topo II poisons, attenuates poison-induced DNA damage signaling mediated by the ATM protein kinase. This is associated with a concomitant loss of poison-induced DNA double- stranded breaks and consequently decreased cytotoxicity following treatment with topo II poisons. This work also demonstrates that salicylate does not block topo II-DNA binding, or trap the enzyme as a closed clamp on DNA. Rather, salicylate blocks DNA cleavage and enzyme-mediated ATP hydrolysis is impaired in a non-competitive manner. Furthermore, salicylate-mediated inhibition of topo II catalytic activity is selective for the alpha isoform of topo II. In investigating the structural determinants modulating potency of topo II inhibition, many compounds with structural similarities to salicylate, including the salicylate-based pharmaceuticals sulfasalazine and diflunisal, were found to also act as catalytic inhibitors of topo II. It was determined that potency is determined by modifications at the 2’-position that are electronegative and capable of donating a hydrogen bond, but that these effects are further influenced by substitutions at the 5’-position. Considered together, the data presented in this thesis establish a new role for a long-established drug.

description: High temperature is one of the leading threats to the plants that severely affects crop quality as well as quantity. Endophytic fungi might be a new tool to safeguard crops against the perilous effects of global warming. In this context, we isolated a thermal stress mitigating endophytic fungus from the fern Dryopteris filix L. The phylogenetic study and 18S rRNA sequence similarity confirmed the potential strain as Aspergillus violaceofuscus. The culture filtrate of A. violaceofuscus exhibited higher concentration of secondary metabolites that enhanced the total chlorophyll content, plant height and biomass of sunflower and soybean seedlings under heat stress. Conversely, the A. violaceofuscus associated plants achieved low levels of reactive oxygen species, abscisic acid, catalase, ascorbic acid oxidase, proline and an overall improved the nutritional value. The current study suggests that A. violaceofuscus can be used as heat stress adaptive tool in crops to achieve sustainable agriculture.

description: In recent years, tremendous progress has been made on scientific Complementary Metal Oxide Semiconductor (sCMOS) sensors, making them a promising device for future space X-ray missions. We have customized a large-format sCMOS sensor, G1516BI, dedicated for X-ray applications. In this work, a 200 nm thick aluminum layer is successfully sputtered on the surface of this sensor. This Al-coated sensor, named EP4K, shows consistent performance with the uncoated version. The readout noise of the EP4K sensor is around 2.5 e- and the dark current is less than 0.01 e-/pixel/s at -30 degree. The maximum frame rate is 20 Hz in the current design. The ratio of single pixel events of the sensor is 45.0%. The energy resolution can reach 153.2 eV at 4.51 keV and 174.2 eV at 5.90 keV at -30 degree. The optical transmittance of the aluminum layer is approximately 1e-8 to 1e-10 for optical lights from 365 to 880 nm, corresponding to an effective aluminum thickness of around 140 to 160 nm. The good X-ray performance and low optical transmittance of this Al-coated sCMOS sensor make it a good choice for space X-ray missions. The Lobster Eye Imager for Astronomy (LEIA), which has been working in orbit for about one year, is equipped with four pieces of EP4K sensors. Furthermore, 48 pieces of EP4K sensors are used on the Wide-field X-ray Telescope (WXT) on the Einstein Probe (EP) satellite, which will be launched at the end of 2023.

description: Two design strategies were investigated to enhance proton conductivity of a proton conducting MOF named β-PCMOF2. First design strategy was isomorphous ligand replacement where an entire C3-symmetric trisulfonate ligand was substituted with a C3-symmetric tris(hydrogen phosphonate) ligand to yield PCMOF2½, which had its proton conductivity raised 1.5 orders of magnitude, to 2.1 × 10-2 S cm-1 at 85 °C and 90% relative humidity compared to the parent material, while maintaining the parent MOF structure. To further enhance the proton conductivity of PCMOF2½, isomorphous ligand replacement was paired with heterocycle doping. Seven new PCMOFs were synthesized and investigated. One resulting material, PCMOF2½(Pyrazole), had its proton conductivity raised 1.9 orders of magnitude compared to the parent material, to 1.1 × 10-1 S cm-1 at 85 °C and 90% relative humidity, while maintaining the parent MOF structure. In addition, the exact mechanism of isomorphous ligand replacement synthesis was elucidated to be a thermodynamically driven solid state reaction.

description: The number of incorporated farms in the United States rose by 140 percent from 1969-78. Tax advantages provided the chief impetus for farmers to incorporate: corporate tax rates declined in the seventies, while individual tax rates rose, mainly because of inflation. Despite the increase in farm corporations, most farms remain sole proprietorships and most incorporated farms are family farms. Nonfamily farms accounted for only 7 percent of farm sales in 1978. Eleven States had enacted legislation as of 1981 to restrict corporate farm activities (farm operations, vertical integration, and ownership of farmland).

description: We analyze the spectrum of the 3-site Bose-Hubbard model with periodic boundary conditions using a semiclassical method. The Bohr-Sommerfeld quantization is applied to an effective classical Hamiltonian which we derive using resonance normal form theory. The derivation takes into account the 1:1 resonance between frequencies of a linearized classical system, and brings nonlinear terms into a corresponding normal form. The obtained expressions reproduce the exact low-energy spectrum of the system remarkably well even for a small number of particles N corresponding to fillings of just two particles per site. Such small fillings are often used in current experiments, and it is inspiring to get insight into this quantum regime using essentially classical calculations.

description: The bioeconomy, a recent addition to the political project of ecological modernization, is largely premised on the widespread use of biomass. Biomass is presented by bioeconomy proponents as renewable and, therefore, sustainable. However, a large body of academic and non-academic literature questions this sustainability, citing the negative socio-ecological aspects of biomass use. Given this contradiction, we ask how the key institutions of the innovation system (government, science, and industry), construct and uphold the image of sustainability of biomass use in the bioeconomy. Through an analysis based on ideology critique, we look at the broad field of biomass policy in Germany, including official bioeconomy strategies and biomass potential calculations, expert portrayals of biomass use in the bioeconomy-themed Year of Science, and an iconic biomass-based commodity. We identify four central ideological strategies that uphold the image of sustainability and contribute to creating political consent for the political project of the German bioeconomy: seeking managerial solutions, relying on technological innovation, relegating solutions into the future, and obscuring the materiality of nature. We discuss how these strategies are upheld by the wider discourse and institutions of ecological modernization and argue that particular attention should be given to the biophysical materiality of living nature in this context. The materiality of nature represents both an obstacle to the ideological strategies identified, and a starting point for envisioning alternative society–nature relations.

description: Abstract
Background: Periodontitis, a chronic inflammatory disease of the supporting structures of the teeth, has been recognized as a potential contributor to the management and progression of Type 2 Diabetes Mellitus (T2DM). T2DM is a metabolic disorder characterized by elevated blood glucose levels, and its control is vital in preventing complications. Objective: To evaluate the association between glycemic control and periodontitis in type-2 diabetes mellitus patients and evaluate their self-management compliance. Methodology: A case-control study was conducted at Dr. Ruth K. M. Pfau Civil Hospital in Karachi to examine the connection between periodontitis and diabetes. The cases and controls were matched for age and gender in a 1:1 ratio. Periodontitis was defined using specific oral health criteria. The participants were interviewed about their self-management pertinent to diabetes followed by periodontal and oral examination. Periodontitis was considered as ≥ two sites with periodontal probing depth >4mm or attachment loss ≥4mm and bleeding on probing gums grade=2.Their current HbA1c level was recorded from their medical history. The data was analyzed using SPSS v.21. Logistic regression was performed to assess the odds of glycemic control and self-management compliance in diabetic patients suffering from periodontitis than among those who did not have periodontitis. Odd ratios (ORs) were considered significant at 95% confidence interval. Results: The unadjusted odds ratio for poor glycemic control (HbA1c >7%) was 6.73 [CI=1.410, 32.173]. However, when adjusted for history of smoking and other addictions, the OR improved by 3.04 [CI= 0.494, 18,699] in cases as compared to controls. Conclusion: Poor periodontal condition appears to be associated with poor glycemic control in diabetics suffering from periodontitis. Improving self-compliance and addressing confounding factors like smoking may have the potential to positively impact both periodontal health and glycemic control in diabetic individuals with periodontitis.

description: The practice of assigning responsibilities to states is central to international affairs but underexplored. States are blamed for wars, called on to apologize, held liable for debts and reparations, tasked with protecting human rights, and bound by treaties. What, if anything, justifies assigning certain responsibilities to states rather than to human beings? This thesis argues that, although there is a rational justification for assigning responsibilities to states, the practice of state responsibility outstrips this justification. The justification for state responsibility follows from the concept or internal logic of responsibility. States have the three faculties that make entities candidates for assignments of responsibility: (1) the ability to take ownership of actions, (2) persistence over time, and (3) the ability to fulfill responsibilities. However, the practice of state responsibility in international relations and international law depends on three ‘fictions’ or assumptions that are not susceptible to rational justification.
A Revised Parallel-Sequence Morphological Classification of Galaxies: Structure and Formation of S0 and Spheroidal Galaxies

description: We update van den Bergh's parallel sequence galaxy classification in which S0 galaxies form a sequence S0a-S0b-S0c that parallels the sequence Sa-Sb-Sc of spiral galaxies. The ratio B/T of bulge to total light defines the position of a galaxy in each sequence. Our classification makes one improvement. We extend the S0a-S0b-S0c sequence to spheroidal ("Sph'") galaxies that are positioned in parallel to irregular galaxies in a similarly extended Sa-Sb-Sc-Im sequence. This provides a natural "home" for spheroidals, which previously were omitted from galaxy classifications. To motivate our juxtaposition of Sph and irregular galaxies, we present photometry and bulge-disk decompositions of Virgo S0s, including late-type S0s that bridge the gap between S0b and Sph galaxies. NGC 4762 is a SB0bc with B/T = 0.13. NGC 4452 is a SB0c galaxy with an even tinier pseudobulge. VCC 2048 and NGC 4638 have properties of both S0cs and Sphs. We update the structural parameter correlations Sphs, irregulars, bulges, and disks. We show that spheroidals of increasing luminosity form a continuous sequence with the disks (but not bulges) of S0c-S0b-S0a galaxies. Remarkably, the Sph--S0-disk sequence is almost identical to that of irregular galaxies and spiral galaxy disks. We review published observations for galaxy transformation processes, particularly ram-pressure stripping of cold gas. We suggest that Sph galaxies are transformed, "red and dead" Scd--Im galaxies in the same way that many S0 galaxies are transformed, red and dead Sa-Sc spiral galaxies

description: This study examines the development of identity, citizenship and sense of belonging among 1.25-generation immigrant youth – those that immigrated to the US between 13-17 years old (Rumbaut, 2004) – in a service-learning oriented afterschool program on the programmatic, local, national, and global-levels using ethnographic and microethnographic methods. Analysis of everyday social interactions between the students, facilitators, and community members of various generational statuses, ethnic backgrounds, and linguistic abilities and their participation in games, team-building exercises, workshops, and service-learning project unmasks the meaning-making process of the educational activities by the students’ and its influence on the perceptions of their own notions of belonging, identity, and citizenship. The data includes over 90 hours of recorded video interactions during the weekly afterschool program sessions, focus groups with students, and individual interviews with focal 1.25-, 1.5-, and second-generation immigrant youth and adult facilitators. The findings show the immigrant youth’s sense of belonging, within the program and in the wider local community context, being shaped and mediated by factors such as spatial positioning, language, the ethnic context, their future goals, and the interactional progression of conversations. Furthermore, their sense of belonging to these different spaces revealed the dynamic process of their identity formation and their complicated perspectives towards citizenship in their new US lives as a number of youth saw their futures not being bound to the US. From the findings, this study offers youth workers and other educators’ pedagogical and curricular recommendations on how to help recent immigrant youth integrate into the classroom community and create activities that support their transnational lives.

description: We investigate the possible effects of short-baseline antinu_e disappearance implied by the reactor antineutrino anomaly on the Double-Chooz determination of theta_{13} through the normalization of the initial antineutrino flux with the Bugey-4 measurement. We show that the effects are negligible and the value of theta_{13} obtained by the Double-Chooz collaboration is accurate only if Delta m^2_{41} is larger than about 3 eV^2. For smaller values of Delta m^2_{41} the short-baseline oscillations are not fully averaged at Bugey-4 and the uncertainties due to the reactor antineutrino anomaly can be of the same order of magnitude of the intrinsic Double-Chooz uncertainties.

description: Most Canadians recognize energy security and energy policy as important topics for discussion. Beginning with the discovery of oil at Leduc Alberta in 1947, Canadian national energy policy formulation has run the gamut from laissez-faire continentalism, to a free-market based deregulated framework. Canada is a major trading nation. Moreover, for the past 75 years, the United States has been Canada’s largest trading partner and in terms of oil trade, 99 percent of Canadian oil exports go to the United States. Canada - U.S. interdependence is central to any discussion of Canadian foreign trade. This thesis examines the current and future state of Canadian crude oil exports, using the Keystone XL project as a case study. By referencing the Keystone XL pipeline, this research will attempt to determine whether interdependence in Canada – U.S. oil trade is actually a dependence which places Canada’s largest natural resource in a perilous position.
Examination of Relationship Between Talent Management Practices and Employee Job-Related Outcomes

description: This study examined the relationship of talent management practices to employee job-related outcomes in the Indian manufacturing setting. Talent management practices included talent acquisition, talent development, talent engagement, and talent retention. Employee job-related outcomes of this study included intent to stay, job engagement, affective commitment, job satisfaction, and employee competency. This study used the social exchange theory and resource based view as the theoretical underpinning for the proposed TM model. The role of organizational culture as a moderator was also examined in the study. The sample of the study consisted of 992 full time employees working in one of largest textiles and paper manufacturing organization of India with facilities located in two Indian states. Data is collected online through a questionnaire composed of several existing survey instruments. Response rate for the survey was high (62.98 percent). The primary method of data analysis was structural equation modeling. Overall, the findings of the analysis showed a number of significant relationships among talent management practices and employee job-related outcomes. There were strong positive relationships between talent acquisition and affective commitment, talent engagement and job satisfaction, talent engagement and affective commitment, and talent retention and employee competency. The findings showed that organizational culture is significantly related to talent management and employee job-related outcomes. However, the organizational culture does moderate the relationship of talent management and employee job-related outcomes. The overall relationship between talent management and employee job-related outcome was found significant and positive. The findings of this study identified a number of implications for the Indian manufacturing organizations. The study also provides a framework of talent management practices for future research.
Analyzing Canadian print media coverage of the 2004 southeast Asian tsunami
Creators: name: Cowen, Brandi Nicole
Publisher: name: University of British Columbia
Year: 2010

description: Using the 2004 Southeast Asian tsunami as a case study, this paper considers how natural disasters are covered in the media in order to develop a better understanding of disaster reporting. The analysis builds upon Alexa Robertson’s 2008 study of television coverage of the tsunami. Data was collected through a content analysis of three daily Canadian newspapers in the three months immediately following the tsunami. The findings show that although there are some notable differences between newspapers, simply catering to the same type of audience (i.e. national) is no guarantee that coverage from different newspapers will produce similar trends. However, the research did identify four trends across the three newspapers studied: pieces that are framed as political stories and critical of the government are not necessarily fuelled by inherent political bias, at least with regard to a foreign natural disaster; in the immediate aftermath of a disaster, the abundance of dramatic stories that can be told raises the threshold with regard to the level of drama a disaster story must have in order to be printed; recovery stories are generally re-framed as aid stories, thereby making it easier to relate the story to the audience, and; there does not seem to be any pattern to when a disaster disappears from newspapers’ front pages, as even an anniversary commemorating a disaster is no assurance of front page coverage. This study found that although narrative arcs in disaster reporting follow similar patterns across newspapers, other aspects of disaster coverage – such as the quantity or location of coverage – vary from newspaper to newspaper.

description: Isomers close to doubly-magic $^{78}_{28}$Ni$_{50}$ provide essential information on the shell evolution and shape coexistence near the ${Z=28}$ and ${N=50}$ double shell closure. We report the excitation energy measurement of the $1/2^{+}$ isomer in $^{79}_{30}$Zn$_{49}$ through independent high-precision mass measurements with the JYFLTRAP double Penning trap and with the ISOLTRAP Multi-Reflection Time-of-Flight Mass Spectrometer. We unambiguously place the $1/2^{+}$ isomer at 942(10) keV, slightly below the $5/2^+$ state at 983(3) keV. With the use of state-of-the-art shell-model diagonalizations, complemented with Discrete Non Orthogonal shell-model calculations which are used here the first time to interpret shape coexistence, we find low-lying deformed intruder states, similar to other ${N=49}$ isotones. The $1/2^{+}$ isomer is interpreted as the band-head of a low-lying deformed structure akin to a predicted low-lying deformed band in $^{80}$Zn, and points to shape coexistence in $^{79,80}$Zn similar to the one observed in $^{78}$Ni. The results make a strong case for confirming the claim of shape coexistence in this key region of the nuclear chart.

description: This thesis studies various aspects of taxation policy covering several essential dimensions such as welfare, politics and tax compliance. The first chapter examines the taxation of financial institutions, the second chapter studies some political aspects of tax policy and the last chapter analyses the effectiveness of a popular tax administration policy in a developing country context. Following the recent financial crisis, there has been considerable policy discussion regarding the taxation of financial institutions. While not front and centre in the public discourse, amongst tax policy experts the VAT treatment of financial institutions has been proven to be very contentious. The first chapter examines the welfare and revenue consequences of a widely practiced VAT policy for financial institutions: exempt treatment. We show that shifting the VAT from exempt treatment to the theoretical ideal of full taxation (the way regular businesses are taxed) is welfare improving and tax revenue increasing. In the second chapter, we study the politics of capital taxation within the context of policy instability and infrastructure investment. Many developing countries rely on private investors to improve their infrastructure. Yet, investors face the risk of opportunistic (tax) policy revisions by the host government, which may adversely impact their return. The results show that countries with high political constraints (and hence, with more policy stability) attract more investment and the magnitude of the impact is larger in the long-run. The final chapter empirically evaluates a new technology for filing tax returns: online filing (e-filing). E-filing has been widely practiced in developed countries for years and it has been argued that it simplifies the procedure and saves time and money for taxpayers. However, it is not self-evident that this should always be the case, especially in developing countries. We find that the effectiveness of the policy depends largely on policy implementation, firm experience with the policy and the infrastructure environment in the country.

description: We report the detection of carbon monoxide (CO) emission from the young supernova remnant Cassiopeia A (Cas A) at wavelengths corresponding to the fundamental vibrational mode at 4.65 micron. We obtained AKARI Infrared Camera spectra towards 4 positions which unambiguously reveal the broad characteristic CO ro-vibrational band profile. The observed positions include unshocked ejecta at the center, indicating that CO molecules form in the ejecta at an early phase. We extracted a dozen spectra across Cas A along the long 1 arcmin slits, and compared these to simple CO emission models in Local Thermodynamic Equilibrium to obtain first-order estimates of the excitation temperatures and CO masses involved. Our observations suggest that significant amounts of carbon may have been locked up in CO since the explosion 330 years ago. Surprisingly, CO has not been efficiently destroyed by reactions with ionized He or the energetic electrons created by the decay of the radiative nuclei. Our CO detection thus implies that less carbon is available to form carbonaceous dust in supernovae than is currently thought and that molecular gas could lock up a significant amount of heavy elements in supernova ejecta.

Nested Landscapes: Ecological and Spiritual Use of Plains Landscape During the Late Prehistoric Period

description: This study evaluates competing models of settlement patterning on the Northwestern Plains using a sample of sites located along the Old North Trail, an ancient pathway within the traditional homeland of the Blackfoot people. More specifically, the sites are located in the Foothills of southern Alberta, the wintering grounds of the Blackfoot. Ecological models suggest that wood, water, bison and shelter are the key influences on human settlement patterns at this time of year. The location of bison herds changes yearly, and any instance of a resource can be used. Consequently, this model expects a random distribution of archaeological sites, though sites should be located where there is access to wood and water. Phenomenological models, by contrast, posit that human groups travel along established paths and stop at the same culturally important places each year. Given such patterned use of the landscape, clusters of archaeological sites at culturally significant landmarks, including glacial erratics, named places, springs and cottonwood groves, are expected. Since human groups return each year, these sites should show evidence of reuse. These suggestions are tested through a series of spatial statistics and descriptive spatial tools which identify spatial patterns and relate site clusters to landscape variables of ecological and cultural significance. This analysis shows that ecological variables influence the selection of the study area as an appropriate wintering ground but do not account for the placement of settlements within the Foothills region. Instead, cultural variables appear to exert a greater influence on human settlement choices, with views of and proximity to named places and glacial erratics important considerations and proximity to cottonwood groves and springs of secondary importance. Consequently, I propose a series of nested landscapes for this portion of the Northwestern Plains in which ecology conditions settlement choices at a large scale and phenomenology at small scale. These insights provide a greater understanding of human use of the Northwestern Plains landscape and contribute to a larger dialogue regarding cultural landscapes, senses of place and ultimately cultural identity.

description: The principles underlying the architectural landscape of chromatin beyond the nucleosome level in living cells remains largely unknown despite its potential to play a role in mammalian gene regulation. We investigated the 3-dimensional folding of a 1 Mbp region of human chromosome 11 containing the β-globin genes by integrating looping interactions of the insulator protein CTCF determined comprehensively by chromosome conformation capture (3C) into a polymer model of chromatin. We find that CTCF-mediated cell type specific interactions in erythroid cells are organized to favor contacts known to occur in vivo between the β-globin locus control region (LCR) and genes. In these cells, the modeled β-globin domain folds into a globule with the LCR and the active globin genes on the periphery. By contrast, in non-erythroid cells, the globule is less compact with few but dominant CTCF interactions driving the genes away from the LCR. This leads to a decrease in contact frequencies that can exceed 1000-fold depending on the stiffness of the chromatin and the exact positioning of the genes. Our findings show that an ensemble of CTCF contacts functionally affects spatial distances between control elements and target genes contributing to chromosomal organization required for transcription.

description: Average per-acre returns differ little for most U.S. corn and soybean farmers using various alternative tillage strategies, according to this analysis of 1980 farm-level production data. Midwest conventional-till soybean farmers, however, accrue a significantly higher average return than do Midwest no-till farmers. Most conservation-till soybean farmers in the three major producing regions incur significantly lower input costs than do conventional-till soybean farmers, but also harvest lower yields except in the Southeast. Significant differences were found in the use of specific corn and soybean inputs among alternative tillage strategies

description: Preference handling and optimization are indispensable means for addressing non-trivial applications in Answer Set Programming (ASP). However, their implementation becomes difficult whenever they bring about a significant increase in computational complexity. As a consequence, existing ASP systems do not offer complex optimization capacities, supporting, for instance, inclusion-based minimization or Pareto efficiency. Rather, such complex criteria are typically addressed by resorting to dedicated modeling techniques, like saturation. Unlike the ease of common ASP modeling, however, these techniques are rather involved and hardly usable by ASP laymen. We address this problem by developing a general implementation technique by means of meta-programming, thus reusing existing ASP systems to capture various forms of qualitative preferences among answer sets. In this way, complex preferences and optimization capacities become readily available for ASP applications.
