description: We explore excitation and ionization by neutron impact as a novel tool for the investigation of electron-electron correlations in helium. We present single and double ionization spectra calculated in accurate numerical ab-initio simulations for incoming neutrons with kinetic energies of up to 150 keV. The resulting electron spectra are found to be fundamentally different from photoioniza- tion or charged particle impact due to the intrinsic many-body character of the interaction. In particular, doubly excited resonances that are strongly suppressed in electron or photon impact become prominent. The ratio of double to single ionization is found to differ significantly from those of photon and charged particle impact.

description: The emergence of online open source repositories in the recent years has led to an explosion in the volume of openly available source code, coupled with metadata that relate to a variety of software development activities. As an effect, in line with recent advances in machine learning research, software maintenance activities are switching from symbolic formal methods to data-driven methods. In this context, the rich semantics hidden in source code identifiers provide opportunities for building semantic representations of code which can assist tasks of code search and reuse. To this end, we deliver in the form of pretrained vector space models, distributed code representations for six popular programming languages, namely, Java, Python, PHP, C, C++, and C#. The models are produced using fastText, a state-of-the-art library for learning word representations. Each model is trained on data from a single programming language; the code mined for producing all models amounts to over 13.000 repositories. We indicate dissimilarities between natural language and source code, as well as variations in coding conventions in between the different programming languages we processed. We describe how these heterogeneities guided the data preprocessing decisions we took and the selection of the training parameters in the released models. Finally, we propose potential applications of the models and discuss limitations of the models.

Interwell Connectivity Evaluation Using Injection and Production Fluctuation Data

Publisher: name: Graduate Studies

Subjects: subject: Engineering--Petroleum
subject: Interwell Connectivity Evaluation

description: Evaluating interwell connectivities can provide important information for reservoir management by identifying flow conduits, barriers, and injection imbalances. Injection and production rates contain connectivity information and a number of methods have been proposed to predict connectivity based on this data. The capacitance model (CM) has recently been applied successfully in several real field cases for this purpose. For non-ideal conditions occurring in the field, however, further investigation on the CM is needed to have a better understanding of reservoir heterogeneity and to facilitate more informed comparisons between the CM results and geological information and other available data. The CM is based on a linear productivity model assuming a pseudo steady state flow regime for slightly compressible fluids. Therefore, we expect within a specific range of fluid and reservoir properties that the results are reliable. The first aim of this work is to determine the range of applicability of the CM before applying it to field data by a sensitivity analysis on accuracy of results. We also briefly address how to extend the model for transient flow regime effects. Secondly, the CM equation is derived from a productivity model assuming radial flow in the drainage area of each producer and most of the pressure drop will occur within a few feet of the wellbore. In this work, we show that heterogeneities close to the wellbore have more effect on production and the CM parameters than interwell heterogeneities between injector-producer pairs. We demonstrate that the CM is able to assess these near producer heterogeneities. Also, we suggest methods to decouple the effects of well geometry from near well heterogeneities. Thirdly, we illustrate the application of the CM in heavy oil reservoirs and wormhole assessment. We propose a modification to the CM to make it perform better in real fields when we have producer shut-ins and mini shut-ins or skin changes. The results of one conventional and one heavy oil field cases are analyzed at the end of this work. Applying earlier methods in real field cases may give misleading connectivity results and inaccurate rate predictions. Adopting the approaches described in this work helps geoscientists and engineers have a better understanding of reservoir heterogeneity and its effects on fluid flow in the reservoir.

A Novel Role of Cdk5 in the Cell Cycle

description: Cyclin-dependent kinase 5 (Cdk5) is a small 33 kDa serine/threonine kinase belonging to the cdk family. It was originally identified based on the structural similarity to Cdk1 (Cdc2) and Cdk2, key regulators of eukaryotic cell cycle progression. Unlike other members of the Cdk family however, Cdk5 is not activated by cyclins, but rather by non- cyclin proteins p35 and p39. The majority of reports regarding Cdk5 relate to neuronal development, particularly in the brain, and so whether Cdk5 functions in cell division has remained a mystery. Further studies by various groups revealed additional roles of Cdk5 outside the neuronal context, including functions in cancer progression. Recently, Cdk5 was shown to play a role in modulating the cell cycle. Here in this study, we further explore the potential function of Cdk5 in cell cycle progression, particularly in non- neuronal cells. Using both siRNA and genetic approaches, we found that the absence of Cdk5 enhances cell proliferation. The loss of Cdk5 causes an upregulation of Cyclin D1 expression, while levels of the cyclin-depdent kinase inhibitor proteins p21 and p27 are reduced. Furthermore, based on flow cytometry analysis, cells lacking Cdk5 results in cells moving from G1 to S faster than normal cells, indicating a potential function in the G1/S transition. Ionizing radiation (IR) studies also reveal that the absence of Cdk5 reduces p53 phosphorylation, and maintains the presence of γH2AX foci, indicating a disruption in DNA repair process, which may cause genomic instability. Collectively, these results support the idea that Cdk5 may play an important role in regulating the cell cycle of non-neuronal cells, particularly at the G1/S transition.

description: Static equilibrium configurations of continua supported by surface tension are given by constant mean curvature (CMC) surfaces which are critical points of a variational problem to extremize the area while keeping the volume fixed. CMC surfaces are used as mathematical models of a variety of continua, such as tiny liquid drops, stars, and nuclei, to play important roles in both mathematics and physics. Therefore, the geometry of CMC surfaces and their properties such as stability are of special importance in differential geometry and in a variety of physical sciences. In this paper we examine the stability of CMC hypersurfaces in arbitrary dimensions, possibly having boundaries on two parallel hyperplanes, by investigating the second variation of the area. We determine the stability of non-uniform liquid bridges or unduloids for the first time in all dimensions and all parameter (the ratio of the neck radius to bulge radius) regimes. The analysis is assisted by numerical computations.

description: The aim of this paper is to create a large geometrical background on the dual 1-jet space J^{1*}(T,M) for a multi-time Hamiltonian approach of the electromagnetic and gravitational physical fields. Our geometric-physical construction is achieved starting only from a given quadratic Hamiltonian function of polymomenta H, which naturally produces a canonical nonlinear connection N, a canonical Cartan N-linear connection CΓ(N) and their corresponding local distinguished (d-) torsions and curvatures. In such a context, we construct some geometrical electromagnetic-like and gravitational-like field theories which are characterized by some natural geometrical Maxwell-like and Einstein-like equations. Some abstract and geometrical conservation laws for the multi-time Hamiltonian gravitational physical field are also given.

description: We use numerical linked cluster (NLC) expansions to compute the specific heat, C(T), and entropy, S(T), of a quantum spin ice model of Yb2Ti2O7 using anisotropic exchange interactions recently determined from inelastic neutron scattering measurements and find good agreement with experimental calorimetric data. In the perturbative weak quantum regime, this model has a ferrimagnetic ordered ground state, with two peaks in C(T): a Schottky anomaly signalling the paramagnetic to spin ice crossover followed at lower temperature by a sharp peak accompanying a first order phase transition to the ferrimagnetic state. We suggest that the two C(T) features observed in Yb2Ti2O7 are associated with the same physics. Spin excitations in this regime consist of weakly confined spinon-antispinon pairs. We suggest that conventional ground state with exotic quantum dynamics will prove a prevalent characteristic of many real quantum spin ice materials.

description: The development of Life Cycle Assessment (LCA) framework that allows for direct comparison with current industrial pathways is required for characterizing GHG emissions impacts and informing economic energy systems decisions regarding an emerging Catalytic Steam Cracking (CSC) partial-upgrading process. Through characterization of the CSC partial-upgrading at a pilot plant scale, industrial scale process modeling and inclusion in a well-to-wheels (WTW) spreadsheet model, the relative emissions impacts of the emerging pathways are directly compared with current dilution and full-upgrading pathways. Consideration for current and future emissions policies allowed for the inclusion of greenhouse gas (GHG) emissions costs in a project investment comparison of CSC partial-upgrading with full-upgrading and dilution options. The case study results for GHG emissions and subsequent economic evaluations suggest that CSC partial-upgrading could have a higher project net present value (NPV) under stringent economy wide carbon prices (>$80 per tonne CO2e).

description: We use supervised learning to identify factors that predict the cross-section of returns and maximum drawdown for stocks in the US equity market. Our data run from January 1970 to December 2019 and our analysis includes ordinary least squares, penalized linear regressions, tree-based models, and neural networks. We find that the most important predictors tended to be consistent across models, and that non-linear models had better predictive power than linear models. Predictive power was higher in calm periods than in stressed periods. Environmental, social, and governance indicators marginally impacted the predictive power of non-linear models in our data, despite their negative correlation with maximum drawdown and positive correlation with returns. Upon exploring whether ESG variables are captured by some models, we find that ESG data contribute to the prediction nonetheless.
Graded cancellation properties of graded rings and graded unit-regular Leavitt path algebras

description: We raise the following general question regarding a ring graded by a group: "If $P$ is a ring-theoretic property, how does one define the graded version $P_{\operatorname{gr}}$ of the property $P$ in a meaningful way?". Some properties of rings have straightforward and unambiguous generalizations to their graded versions and these generalizations satisfy all the matching properties of the nongraded case. If $P$ is either being unit-regular, having stable range 1 or being directly finite, that is not the case. The first part of the paper addresses this issue. Searching for appropriate generalizations, we consider graded versions of cancellation, internal cancellation, substitution, and module-theoretic direct finiteness. In the second part of the paper, we turn to Leavitt path algebras. If $K$ is a trivially graded field and $E$ is an oriented graph, the Leavitt path algebra $L_K(E)$ is naturally graded by the ring of integers. If $E$ is a finite graph, we present a property of $E$ which is equivalent with $L_K(E)$ being graded unit-regular. This property critically depends on the lengths of paths to cycles making it stand out from other known graph conditions which characterize algebraic properties of $L_K(E).$ It also further illustrates that graded unit-regularity is quite restrictive in comparison to the alternative generalization of unit-regularity which we consider in the first part of the paper.

description: We present a new theoretical calibration of the Stroemgren metallicity index hk by using alpha-enhanced evolutionary models transformed into the observational plane by using atmosphere models with the same chemical mixture. We apply the new Metallicity--Index--Color (MIC) relations to a sample of 85 field red giants (RGs) and find that the difference between photometric estimates and spectroscopic measurements is on average smaller than 0.1 dex with a dispersion of sigma = 0.19 dex. The outcome is the same if we apply the MIC relations to a sample of eight RGs in the bulge globular cluster NGC6522, but the standard deviation ranges from 0.26 (hk, v-y) to 0.49 (hk, u-y). The difference is mainly caused by a difference in photometric accuracy. The new MIC relations based on the (Ca-y) color provide metallicities systematically more metal-rich than the spectroscopic ones. We found that the Ca-band is affected by Ca abundance and possibly by chromospheric activity.

Detecting Missing Dependencies and Notifiers in Puppet Programs

description: Puppet is a popular computer system configuration management tool. It provides abstractions that enable administrators to setup their computer systems declaratively. Its use suffers from two potential pitfalls. First, if ordering constraints are not specified whenever an abstraction depends on another, the non-deterministic application of abstractions can lead to race conditions. Second, if a service is not tied to its resources through notification constructs, the system may operate in a stale state whenever a resource gets modified. Such faults can degrade a computing infrastructure's availability and functionality. We have developed an approach that identifies these issues through the analysis of a Puppet program and its system call trace. Specifically, we present a formal model for traces, which allows us to capture the interactions of Puppet abstractions with the file system. By analyzing these interactions we identify (1) abstractions that are related to each other (e.g., operate on the same file), and (2) abstractions that should act as notifiers so that changes are correctly propagated. We then check the relationships from the trace's analysis against the program's dependency graph: a representation containing all the ordering constraints and notifications declared in the program. If a mismatch is detected, our system reports a potential fault. We have evaluated our method on a large set of Puppet modules, and discovered 57 previously unknown issues in 30 of them. Benchmarking further shows that our approach can analyze in minutes real-world configurations with a magnitude measured in thousands of lines and millions of system calls.

Emancipation, empowerment and embodiment : exploring the influence of organizational dynamics on one school's journey to promote positive behaviour and social responsibility
Creators: name: White, Vincent
Publisher: name: University of British Columbia
Year: 2010

description: Over the course of an eighteen-month period, the staff and students at a K-7 elementary school were engaged in a district-sponsored pilot project that examined new and existing approaches to promoting positive behaviour within their school community. This research, conducted by a member of the school’s staff, retraces this investigative journey to explore various dynamics related to the approaches used by him, his teaching colleagues, and the school’s administration to increase social responsibility within the student population. Situated within an emergent methodological design, this study employed a variety of investigative approaches in a manner informed by Joe Kincheloe’s (2004) conceptualization of the bricolage. Data collected included researcher field notes that reflect everyday observations of project-related events, as well as informal discussions with staff and administration about their ongoing impressions of the school’s approach to behaviour, digital audio recordings of project meetings, and interviews with teachers and administrators during the final weeks of the pilot. The researcher’s ongoing process of self-conscious reflexivity, specifically in relation to his dual role as the researcher and a member of the school’s staff, is also included in the data and is used to examine some of the ethical and methodological dilemmas that emerged at various stages of this undertaking. Analysis of this data was purposefully conducted to examine how perceptions of authority and accountability are organizationally situated within a school community in ways that both support and resist efforts to promote positive student behaviour through proactive and reactive approaches. This research explores some of the organizational dynamics related to introducing and sustaining a new initiative in a school community, including communication patterns commonly employed by staff and administration when tensions emerge as a result of efforts to affect change in professional practice. The study identifies divisive and unifying features of various behaviour approaches employed by a school to encourage social responsibility, and how these underscore the importance of staff and student empowerment in establishing a safe and caring learning community. The implications of this research for educational leadership and professional development with respect to promoting positive behaviour in schools are discussed. Areas for further investigation are highlighted.

description: A three-parameter equation of state (EOS) without physically incorrect oscillations is proposed based on the generalized Lennard-Jones (GLJ) potential and the approach in developing linear isotherm regularity (LIR) EOS of Parsafar and Mason [J. Phys. Chem., 1994, 49, 3049]. The proposed (GLIR) EOS can include the LIR EOS therein as a special case. The three-parameter GLIR, Parsafar and Mason (PM) [Phys. Rev. B, 1994, 49, 3049], Shanker, Singh and Kushwah (SSK) [Physica B, 1997, 229, 419], Parsafar, Spohr and Patey (PSP) [J. Phys. Chem. B, 2009, 113, 11980], and reformulated PM and SSK EOSs are applied to 30 metallic solids within wide pressure ranges. It is shown that the PM, PMR and PSP EOSs for most solids, and the SSK and SSKR EOSs for several solids, have physically incorrect turning points, and pressure becomes negative at high enough pressure. The GLIR EOS is capable not only of overcoming the problem existing in other five EOSs where the pressure becomes negative at high pressure, but also gives results superior to other EOSs.

description: Minimum resolution set and associated metric dimension provide the basis for unique and systematic labeling of nodes of a graph using distances to a set of landmarks. Such a distance vector set, however, may not be unique to the graph and does not allow for its exact construction. The concept of construction set is presented, which facilitates the unique representation of nodes and the graph as well as its exact construction. Link dimension is the minimum number of landmarks in a construction set. Results presented include necessary conditions for a set of landmarks to be a construction set, bounds for link dimension, and guidelines for transforming a resolution set to a construction set.

description: There is a growing interest for cities around the world to focus on creating more walkable and bikeable communities in order to realize societal benefits which include improved public health and safety, reduced environmental impacts, increased economic benefits, and increased quality of life. In this research, the characteristics of non-work travel were explored, with a focus on those trips made on foot and by bicycle, and implications to transportation and land use policy and practices are suggested. The geographic scope of this thesis was Calgary, Alberta, Canada, with travel behaviour responses (n=410) being collected through the use of an online survey tool. The specific characteristics of non-work travel explored include: mode split; travel mode to work versus travel mode for non-work; trip distance and trip frequency; time of day and day of week of travel; effect of weather and temperature on travel, and the trip origins of non-work trips.

description: Gene regulatory networks (GRNs) are complex systems in which many genes regulate mutually to adapt the cell state to environmental conditions. In addition to function, the GRNs possess several kinds of robustness. This robustness means that systems do not lose their functionality when exposed to disturbances such as mutations or noise, and is widely observed at many levels in living systems. Both function and robustness have been acquired through evolution. In this respect, GRNs utilized in living systems are rare among all possible GRNs. In this study, we explored the fitness landscape of GRNs and investigated how robustness emerged in highly-fit GRNs. We considered a toy model of GRNs with one input gene and one output gene. The difference in the expression level of the output gene between two input states, "on" and "off", was considered as fitness. Thus, the determination of the fitness of a GRN was based on how sensitively it responded to the input. We employed the multicanonical Monte Carlo method, which can sample GRNs randomly in a wide range of fitness levels, and classified the GRNs according to their fitness. As a result, the following properties were found: (1) Highly-fit GRNs exhibited bistability for intermediate input between "on" and "off". This bistability emerges necessarily as fitness increases. (2) These highly-fit GRNs were robust against noise because of their bistability. (3) GRNs that were robust against mutations were not extremely rare among the highly-fit GRNs. This implies that mutational robustness is readily acquired through the evolutionary process.

description: We calculate the growth rate of the complexity function for polytopal cut and project sets. This generalises work of Julien where the almost canonical condition is assumed. The analysis of polytopal cut and project sets has often relied on being able to replace acceptance domains of patterns by so-called cut regions. Our results correct mistakes in the literature where these two notions are incorrectly identified. One may only relate acceptance domains and cut regions when additional conditions on the cut and project set hold. We find a natural condition, called the quasicanonical condition, guaranteeing this property and demonstrate via counterexample that the almost canonical condition is not sufficient for this. We also discuss the relevance of this condition for the current techniques used to study the algebraic topology of polytopal cut and project sets.

description: The Hilbert Series (HS) of the moduli space of two G instantons on C^2, where G is a simple gauge group, is studied in detail. For a given G, the moduli space is a singular hyperKahler cone with a symmetry group U(2) \times G, where U(2) is the natural symmetry group of C^2. Holomorphic functions on the moduli space transform in irreducible representations of the symmetry group and hence the Hilbert series admits a character expansion. For cases that G is a classical group (of type A, B, C, or D), there is an ADHM construction which allows us to compute the HS explicitly using a contour integral. For cases that G is of E-type, recent index results allow for an explicit computation of the HS. The character expansion can be expressed as an infinite sum which lives on a Cartesian lattice that is generated by a small number of representations. This structure persists for all G and allows for an explicit expressions of the HS to all simple groups. For cases that G is of type G_2 or F_4, discrete symmetries are enough to evaluate the HS exactly, even though neither ADHM construction nor index is known for these cases.

Diachronic research on community interpreting : Between interpreting, linguistics and social sciences

description: This chapter aims to present the interdisciplinary character of (diachronic) research on commu- nity interpreting by presenting an ongoing project on the communicative situation of the migrant workers from Galicia (Spain) in Hanover (Germany) in the 1960s and 70s and their need for community interpreting. In order to be able to thoroughly describe the language mediation among this migrant group, it was imperative to provide a detailed linguistic description of the Galician community in Hanover. The theoretical foundations of the project lie therefore on two different and relatively new disci- plines: community interpreting within the field of interpreting studies and migration linguistics within the applied linguistics. The diachronic nature of the object of study posed some additional methodological challenges. Being one of the main research problems on interpreting the creation of the corpus, oral history, within social sciences, supplied the guidelines and strategies for conducting narrative interviews, which form the empirical basis of the study. As for the analysis methodology, qualitative content analysis provided a flexible though systematic model to qualitatively analyse a corpus based on linguistic material, such as semi-structured interviews.
The extra-religious functions of madaris : implications for community planning in Pakistan
Creators: name: Aijazi, Omer
Publisher: name: University of British Columbia
Year: 2010

description: The current mantra of development advocates macro level, top down approaches which largely ignore the potential for change inherent within existing indigenous grass root social structures. One such indigenous social institution prevalent in the Islamic World is that of the religious school locally known as the madrassa. After 9-11, madaris have been prominently featured in the international media as a potential breeding ground for terrorists and fundamentalists and has become a policy concern for both the American and Pakistani governments. Recent policy interventions have included steps to centralize madaris, curriculum revisions along with a renewed interest in improving existing public and private schools as an alternative to religious schooling. Most of these steps have been rejected by the madrassa community and there is ongoing antagonism between madrassa officials and government authorities. This research examines how madrassa mission and mandate intersect with community development goals as well as with the national project of development and modernity, and how they create linkages and multiplier effects within the local culture and institutions particularly in the absence of social support services. It utilizes a mixed method approach based on ethnographic interviews, mapping, content and discourse analyses and participant observations to uncover the daily patterns of the research participants’ lives in two selected research sites in Islamabad, Pakistan. The research develops recommendations based on the perspective of madrassa students, alumni, administrators, teachers and local community members. The study argues that madaris have the ability to reach out to Pakistan’s marginalized and disenfranchised. It is important for the madaris community to get recognized by the state to gain access to state funding and aid agencies. However the government needs to be very flexible with its policy of reforms and needs to allow the madaris to operate in the academic spaces they deem fit. The purpose and intent of madaris should be preserved and allowed to remain intact. This is where planners and development practioners fit in. They need to mobilize a participatory dialogue between the state and the madaris community and exact this crucial integration of indigenous institutions such as the madrassa into mainstream development policy.

description: We present an improved formula for the anomalous radial velocity of the star during planetary transits due to the Rossiter-McLaughlin (RM) effect. The improvement comes from a more realistic description of the stellar absorption line profiles, taking into account stellar rotation, macroturbulence, thermal broadening, pressure broadening, and instrumental broadening. Although the formula is derived for the case in which radial velocities are measured by cross-correlation, we show through numerical simulations that the formula accurately describes the cases where the radial velocities are measured with the iodine absorption-cell technique. The formula relies on prior knowledge of the parameters describing macroturbulence, instrumental broadening and other broadening mechanisms, but even 30% errors in those parameters do not significantly change the results in typical circumstances. We show that the new analytic formula agrees with previous ones that had been computed on a case-by-case basis via numerical simulations. Finally, as one application of the new formula, we reassess the impact of the differential rotation on the RM velocity anomaly. We show that differential rotation of a rapidly rotating star may have a significant impact on future RM observations.

Possible dark energy imprints in gravitational wave spectrum of mixed neutron-dark-energy stars

description: In the present paper we study the oscillation spectrum of neutron stars containing both ordinary matter and dark energy in different proportions. Within the model we consider, the equilibrium configurations are numerically constructed and the results show that the properties of the mixed neuron-dark-energy star can differ significantly when the amount of dark energy in the stars is varied. The oscillations of the mixed neuron-dark-energy stars are studied in the Cowling approximation. As a result we find that the frequencies of the fundamental mode and the higher overtones are strongly affected by the dark energy content. This can be used in the future to detect the presence of dark energy in the neutron stars and to constrain the dark-energy models.

description: The electronic properties of twisted bilayer graphene on SiC substrate were studied via combination of transport measurements and scanning tunneling microscopy. We report the observation of enhanced intervalley scattering from one Dirac cone to the other, which contributes to weak localization, of the twisted bilayer graphene by increasing the interlayer coupling strength. Our experiment and analysis demonstrate that the enhanced intervalley scattering is closely related to the periodic AB stacked atoms (the A atom of layer 1 and the B atom of layer 2 that have the same horizontal positions) that break the sublattice degeneracy of graphene locally. We further show that these periodic AB stacked atoms affect intervalley but not intravalley scattering. The result reported here provides an effective way to atomically manipulate the intervalley scattering of graphene.

description: The anomalous Hall effect (AHE) in the Heusler compounds Co$_{2}$FeSi and Co$_{2}$FeAl is studied in dependence of the annealing temperature to achieve a general comprehension of its origin. We have demonstrated that the crystal quality affected by annealing processes is a significant control parameter to tune the electrical resistivity $ρ_{xx}$ as well as the anomalous Hall resistivity $ρ_{ahe}$. Analyzing the scaling behavior of $ρ_{ahe}$ in terms of $ρ_{xx}$ points to a temperature-dependent skew scattering as the dominant mechanism in both Heusler compounds.
