description: Although the spatial association of iron-rich lavas and high-amplitude magnetic anomalies is well documented, a causal link between enhanced iron content and high remanent magnetization has been difficult to establish. Here we report magnetic data from approximately 250 samples, with 8-16% FeO* (total iron as FeO), from the southern East Pacific Rise (EPR) that provide strong support for the presumed geochemical dependence of remanent intensity. The limited age range (0-6 ka) of axial lavas from this ultrafast spreading ridge (~150 mm/yr full rate) effectively minimizes variations resulting from time dependent changes in geomagnetic intensity or low-temperature alteration. Systematic sampling relative to the chilled margin illustrates that substantial grain size-related variations in magnetic properties occur on a centimeter scale. Both microprobe data and Curie temperatures suggest that the average groundmass titanomagnetite composition in the southern EPR samples is approximately constant (modal modified ulvöspinel content = 0.67) over a wide range of lava compositions. Saturation magnetization and saturation remanence are highly correlated with FeO* (R = 0.73 and 0.83, respectively), indicating that more iron-rich lavas have higher abundances of otherwise similar titanomagnetite. We show that there is a good correlation between natural remanent magnetization (NRM) and FeO*, provided that sufficient specimens are used to determine the average NRM of a sample (R = 0.63). Because the range of iron contents in mid-ocean ridge basalts is limited, the best fit slope (4.44 A/m per %FeO* in an ambient field of 0.030 mT) should provide reasonable bounds on the equatorial magnetization of submarine lavas (~10 A/m at 8.5% FeO* and ~50 A/m at ~16% FeO*). Finally, we demonstrate that along-axis variations in NRM closely parallel geochemical changes along the southern EPR. Where magnetization values deviate significantly from those predicted from the range of measured FeO* contents, these discrepancies may reflect additional unrecognized geochemical variability.

description: We consider quantum aspects of a class of generalized Gross-Neveu models, which in special cases reduce to sigma models. We show that, in the case of gauged models, an admissible gauge is $A_μ=0$, which is a direct analogue of the conformal gauge in string models. Chiral anomalies are a gauge counterpart of the Weyl anomaly, and are required to vanish. Topological effects on the worldsheet lead to an integration over moduli spaces of connections on a Riemann surface. This is an initial step in studying the effects of worldsheet geometry and topology in integrable sigma models.

A data-driven model for spectra: Finding double redshifts in the Sloan Digital Sky Survey

description: We present a data-driven method - heteroscedastic matrix factorization, a kind of probabilistic factor analysis - for modeling or performing dimensionality reduction on observed spectra or other high-dimensional data with known but non-uniform observational uncertainties. The method uses an iterative inverse-variance-weighted least-squares minimization procedure to generate a best set of basis functions. The method is similar to principal components analysis, but with the substantial advantage that it uses measurement uncertainties in a responsible way and accounts naturally for poorly measured and missing data; it models the variance in the noise-deconvolved data space. A regularization can be applied, in the form of a smoothness prior (inspired by Gaussian processes) or a non-negative constraint, without making the method prohibitively slow. Because the method optimizes a justified scalar (related to the likelihood), the basis provides a better fit to the data in a probabilistic sense than any PCA basis. We test the method on SDSS spectra, concentrating on spectra known to contain two redshift components: These are spectra of gravitational lens candidates and massive black-hole binaries. We apply a hypothesis test to compare one-redshift and two-redshift models for these spectra, utilizing the data-driven model trained on a random subset of all SDSS spectra. This test confirms 129 of the 131 lens candidates in our sample and all of the known binary candidates, and turns up very few false positives.

Evaluation of strategic software investments for the Canadian cabinet industry
Creators: name: Hewitt, Richard
Publisher: name: University of British Columbia
Year: 2012

description: Manufacturing is the single largest sector of the Canadian economy, accounting for 12.7% of the nation’s GDP in 2009 (Statistics Canada 2011). Over the past decade, this sector has faced numerous challenges such as a stronger Canadian dollar, increased foreign competition, and the recent decline of the US economy. One of the ways Canadian manufacturers have responded to these challenges is through increased information technology (IT) investments (Baldwin & Sabourin 2004). Wood products industries, though, generally invest much less in IT than the sector as a whole (Atrostic & Gates 2001). When wood manufacturers do invest in IT, it is often at a very basic level (Hewitt et al. 2011). Consequently, more intensive and sophisticated use of IT presents an opportunity for the cabinet industry to improve their competitive position. The first research objective was to determine the types of software products currently available to the cabinet industry and their associated functionalities. This was done using simple proportions, cluster analysis, and association rule learning. Next, a strategic analysis of which types of software applications are most important for the industry’s future competitiveness was done using the analytic network process. Lastly, any large gaps between what is currently represented in the industry and what is important for future competitiveness were identified. Operations & Engineering functionalities were found in 65.7% of all observed functionalities, whereas Content, Collaborative, and CRM functionalities were found in less than 10% each. Operations & Engineering and ERM software were determined to be the most important for future competitiveness because of their contribution to the Quality strategy. While Operations & Engineering software is important for the industry, they may be overrepresented because the current market is highly saturated with these functionalities. ERM, Collaborative, and CRM software are underrepresented as their future priority is higher than their current presence. The sensitivity analysis shows that the final priorities of software applications are most sensitive to the weighting of the Customer Service strategy. If an individual firm places a high emphasis on customer service and marketing, then CRM and Collaborative software become most critical for success.

description: The US has prospered by recognizing the value of public resources and providing neutral experts able to facilitate the use of those resources whether by citizens or businesses. The Land-Grant Universities come to mind as an early example in US history when the US Congress passed the Morrill Act authorizing the selling of federal property to fund the creation of state universities focused on agricultural and technical education. Land Grants were followed by Sea Grants, Space Grants, and Sun Grants with each program following a slightly different federal funding or authorization model. In the case of Land Grants, Congress recognized the need for experts to go beyond the academic teaching of the Land-Grant Universities and authorized the creation of Land-Grant Cooperative Extension Services thereby bringing experts to rural communities with the passage of the Smith-Lever Act of 1914. While each of these traditional public resources were and are valuable economic drivers for this country there are others that might be currently more significant. Specifically, it is time to recognize that data, or at least data that is publicly funded, is one of the greatest public trust resources of the 21st century. While many institutions are supporting data-related initiatives there is still a strong need for the equivalent of a Data Grant.
Segmentation of Mobile LiDAR Point Clouds in Urban Environment

description: Mobile LiDAR System (MLS) is a popular tool which collects 3D information while vehicles drive along urban streets. Nowadays, MLS becomes more and more important in obtaining 3D point clouds because of its efficiency and cost-effectiveness. One demanding issue is how to segment objects from MLS point clouds accurately and efficiently. Due to the fact that LiDAR point clouds are noisy, uneven and the lack of topology, the object segmentation has become a challenging task. This thesis aims to provide promising solutions for segmentation of MLS point clouds. In the beginning, this thesis proposes an elevation-based method to split MLS point clouds into ground points and off-ground points. Then, it presents an accurate method to extract road curbs from ground points. Contributions of the proposed curb extraction method include that, it formulates an energy function to extract candidate curb points, and it completes curb paths by a new least cost path model. As this curb extraction method works on the 3D points directly rather than on the 2D projected data, there is no loss of 3D geometry information, which improves the extraction performance. For the off-ground object segmentation, two new methods are introduced in this thesis. The first method is an optimal hierarchical clustering (OHC) approach. The cluster combination in the hierarchical clustering is formulated as a problem of the bipartite graph matching, which is optimally solved by the minimum-cost perfect matching (McPM) of a point-based graph. The second method is a component-level segmentation approach for dealing with the separation of overlapping objects. Contributions of the second method include that, it formulates an optimal-vector-field to provide the component consistency information for object segmentation, and it presents a strategy for multi-object segmentation using binary labels only. Due to the fact that power lines are divided into pieces by the previous object segmentation methods, the final work is to extract power lines from input data. Contributions include that, it proposes an estimator to enhance the segmentation robustness against Gaussian noise, and it groups segmented components into individual power line spans based on linear structure information.

description: Microbiologists have historically been struck by both the beautiful pigmentation of phenazine-producing cultures and the high degree of variability in phenazine production among isolates, conditions, and even repeat experiments. Motivated by an interest in controlling phenazine biosynthesis, they have identified many of the factors that affect the regulation of this process. Phenazine production is controlled by complex regulatory networks. The variability of phenazine production can be explained in part by the effects of environmental conditions on these networks and by strain-specific differences in these networks. In this chapter, we describe the components of a common regulatory cascade that is represented in many phenazine-producing pseudomonads. Membrane sensor proteins and two component sensors control the activity of downstream regulators such as quorum sensing systems and RNA-binding proteins and small RNAs; these cytoplasmic regulators then control the production of phenazine biosynthetic proteins. We highlight examples from specific strains and cases where the mechanistic links may vary among them. We also discuss environmental parameters that have been shown to affect phenazine biosynthesis and compare their effects in different isolates. Ongoing work will further elaborate the details of the environmental sensing and regulatory responses that control production of these dramatically colored compounds. New findings have the potential to support enhanced application of phenazine-producing strains in agriculture, where they promote crop health, and the treatment of infections in which phenazines contribute to bacterial pathogenicity.

Drawing inspiration from depth psychology, philosophy, and literature, and based on my study of relevant artists and their practice, I worked to create an immersive installation environment. In deconstructing and simplifying a selection of archetypal forms, I seek to allow the viewer to relate the strangeness of my own interpretations to experiences of their own. I have strove to achieve this by presenting a non-linear narrative experience using a variety of objects unfolding in a rhizome-like pattern, that suggests an allegorical journey through an inner landscape.

description: If E is an elliptic curve defined over a number field and p is a prime of good ordinary reduction for E, a theorem of Rubin relates the p-adic height pairing on the p-power Selmer group of E to the first derivative of a cohomologically defined p-adic L-function attached to E. Bertolini and Darmon have defined a sequence of "derived" p-adic heights. In this paper we give an alternative definition of the p-adic height pairing and prove a generalization of Rubin's result, relating the derived heights to higher derivatives of p-adic L-functions. We also relate degeneracies in the derived heights to the failure of the Selmer group of E over a Z_p-extension to be "semi-simple" as an Iwasawa module, generalizing results of Perrin-Riou.

description: Inspired by prior work on stabilized auditory image features, we have developed novel auditory-model-based features that preserve the fine time structure lost in conventional frame-based features. While the original auditory model is computationally intense, we present a simpler system that runs about ten times faster but achieves equivalent performance. We use these features for video soundtrack classification with the Columbia Consumer Video dataset, showing
that the new features alone are roughly comparable to traditional MFCCs, but combining classifiers based on both features achieves a 15% improvement in mean Average Precision over the MFCC baseline.

description: The deliverable is focused on creating a reference architecture for a health data portal that follows the FAIR principles (Findable, Accessible, Interoperable, and Reusable). The portal is intended to serve as an access point for various users and provide them with relevant information. The first step is to identify the different user profiles that will interact with the portal, such as citizens, researchers, and infrastructure providers, as each user group has different expectations and needs. The report categorizes these user profiles into fourteen categories based on legal roles, temporal aspects, and other relevant factors. Eight main profiles are defined, along with sub-profiles to accommodate diverse user demands. The deliverable also introduces user personae, which represent typical users and their goals, challenges, needs, and expectations from the FAIR data portal. These personae help in understanding the future users of the portal. The ultimate goal of this effort is to design a reference architecture for the FAIR health data portal, which will enable the interoperability of existing resources by defining the necessary information for their connection. The work done in other HealthyCloud work packages, particularly WP3 and WP4, is important for identifying data-oriented resources and will contribute to the overall goals of WP6 and the development of the FAIR health data portal.

description: For certain restricted computational tasks, quantum mechanics provides a provable advantage over any possible classical implementation. Several of these results have been proven using the framework of measurement-based quantum computation (MBQC), where non-locality and more generally contextuality have been identified as necessary resources for certain quantum computations. Here, we consider the computational power of MBQC in more detail by refining its resource requirements, both on the allowed operations and the number of accessible qubits. More precisely, we identify which Boolean functions can be computed in non-adaptive MBQC, with local operations contained within a finite level in the Clifford hierarchy. Moreover, for non-adaptive MBQC restricted to certain subtheories such as stabiliser MBQC, we compute the minimal number of qubits required to compute a given Boolean function. Our results point towards hierarchies of resources that more sharply characterise the power of MBQC beyond the binary of contextuality vs non-contextuality.

description: It is straightforward to determine the size of the Earth and the distance to the Moon without making use of a telescope. The methods have been known since the 3rd century BC. However, few amateur or professional astronomers have worked this out from data they themselves have taken. Here we use a gnomon to determine the latitude and longitude of South Bend, Indiana, and College Station, Texas, and determine a value of the radius of the Earth of 6290 km, only 1.4 percent smaller than the true value. We use the method of Aristarchus and the size of the Earth's shadow during the lunar eclipse of 2011 June 15 to derive an estimate of the distance to the Moon (62.3 R_Earth), some 3.3 percent greater than the true mean value. We use measurements of the angular motion of the Moon against the background stars over the course of two nights, using a simple cross staff device, to estimate the Moon's distance at perigee and apogee. Finally, we use simultaneous CCD observations of asteroid 1996 HW1 obtained with small telescopes in Socorro, New Mexico, and Ojai, California, to derive a value of the Astronomical Unit of (1.59 +/- 0.19) X 10^8 km, about 6 percent too large. The data and methods presented here can easily become part of a beginning astronomy lab class.

Speech/music discrimination based on posterior probability features

description: A hybrid connectionist-HMM speech recognizer uses a neural network acoustic classifier. This network estimates the posterior probability that the acoustic feature vectors at the current time step should be labelled as each of around 50 phone classes. We sought to exploit informal observations of the distinctions in this posterior domain between nonspeech audio and speech segments well-modeled by the network. We describe four statistics that successfully capture these differences, and which can be combined to make a reliable speech/nonspeech categorization that is closely related to the likely performance of the speech recognizer. We test these features on a database of speech/music examples, and our results match the previously-reported classification error, based on a variety of special-purpose features, of 1.4% for 2.5 second segments. We also show that recognizing segments ordered according to their resemblance to clean speech can result in an error rate close to the ideal minimum over all such subsetting strategies.

description: We consider the prospects for a neutrino factory to measure mixing angles, the CP violating phase and mass-squared differences by detecting wrong-charged muons arising from the chain μ^+ to ν_e to ν_μ to μ^- and the right-charged muons coming from the chain μ^+ to \barν_μ to \barν_μ to μ^+ (similar to μ^- chains), where ν_e to ν_μ and \barν_μ to \barν_μ are neutrino oscillation channels through a long baseline. First, we perform the baseline and energy optimization of the neutrino factory including the latest simulation results from the magnetized iron neutrino detector (MIND). Second, we study physics with near detectors and consider the treatment of systematic errors including cross section errors, flux errors, and background uncertainties. Third, the effects of one additional massive sterile neutrino are investigated in the context of near and far detector combinations.

But the ideas of the new generation don't invalidate the
work done by those who came before. In fact, change in libraries
tends to be a lot more evolutionary than revolutionary.
And while generational and technological divides have always
been with us, Freedman concluded, "when others have at least

silly not to glean what we can from their experience."

description: Accelerated by technology, our pharmaceutical, biotechnology and medical device industries are changing at the speed of light. With these technological changes, some management personnel seem to believe that if processes are controlled by technology, lesser qualified personnel can fill many roles in the clinical trials. In some companies, this leads to a dangerous disconnect where technology improves, but the quality of the personnel diminishes and data integrity is therefore put at risk. Compounding this trend is a misplaced trust in robots and computers, and insufficient numbers of personnel to grow into the shoes of retiring seasoned veterans. In this session several examples will be provided where the most basic of human errors go undetected by personnel in clinical trials; errors that were not or could not be detected by electronic systems used to ensure data integrity. Several other examples will be provided from the aerospace and the healthcare industry. In our industry, human creativity and ingenuity abound and should flourish, however it is incumbent on all champions of quality to ensure that the source of data integrity is recognized as: • The result of well-developed technical prowess as well as a well-developed workforce armed with basic and fundamental stewardship skills and • An awareness and integration of the larger view, combined with an eye for detail to establish a solid foundation for data integrity across any situation or platform. We will provide perspectives and suggestions to address this challenging situation, helping to ensure clinical data integrity vital for FDA decision making.

Tobacco exposure and breast cancer : perspectives of young women
Creators: name: Ptolemy, Erin Christine
Publisher: name: University of British Columbia
Year: 2012

description: Based on available evidence researchers have concluded that young women who smoke or have regular long-term exposure to secondhand smoke (SHS) have an increased risk of developing premenopausal breast cancer. To date there have been few efforts aimed at raising awareness among young women about this modifiable risk factor for breast cancer. The aim of this research was to further knowledge about young women aged 15 to 24 as an audience for messaging about tobacco smoke and breast cancer. Young women (n=121) responded to an online survey examining perceived importance of and interest in risk and risk reduction information, as well as potential barriers and strategies to messaging related to tobacco smoke and breast cancer risk. Participants ranged in age from 15 to 24 years, with the average age of participants being 21 years (SD= 2.21). The findings indicate that in general young women were interested in information about tobacco exposure as a risk factor for breast cancer. Most participants identified that information about smoking and SHS is important to them at this stage of their life, and most participants reported that they were interested in learning about how to reduce their risk for tobacco-related breast cancer. Age was found to be an important factor influencing young women’s perceptions, with young adults holding more favourable attitudes towards information about breast cancer and smoking than teens. Potential barriers to messaging that young women identified include lack of motivation to find this information, not thinking about the long-term consequences of their actions, and beliefs that breast cancer is “something older women get”. Messaging strategies participants perceived as effective included providing young women with facts and personal stories of breast cancer, hearing about this information from peers, and targeting all smokers who place young women at risk for breast cancer with public awareness messages about smoking and breast cancer. These findings have important implications for future research, health messaging, policy development, and practice.

One of the key ways that immigrant identity is formed in this space is through cultural religiosity. Despite the fact that Plaza Mexico is a shopping mall, the place gathers participation from Mexican immigrants and Latinos of other national origins at key times of religious expression during the year. Following what Holloway calls 'enchanted space', we analyse the Day of the Dead celebration (2 November) and the Virgen de Guadalupe celebration (during and after 12 December) to discuss the transformation of the mall into a multidimensional place that encompasses secular, religious, cultural and political expressions. We show how Plaza Mexico provides a rich location from which to understand transnational cultural connections and familial transmissions of culture between different generations of immigrants which we term 'affective connectivity'.

description: This thesis explores the importance of birds in paleodietary reconstruction based on stable isotope analysis, using faunal remains from Arctic contexts as a case study. In the Arctic, migratory birds and their eggs have been important seasonal resources for hunter-gatherer populations, and while evidence of their utilization in the faunal record is apparent, their use is less clear from the isotopic record. Zooarchaeological analysis was carried out on a large sample of bird remains from Pre-Dorset and Dorset sites located on the Knud Peninsula of Ellesmere Island to assess bird hunting and processing amongst Paleo-Inuit groups. A subset of these archaeological bird remains were analyzed to determine the variation in avian isotopic signatures which was expected to differ from terrestrial and sea mammal isotopic signatures. An experimental study was carried out to test the assumption that the spacing between avian tissues (bone collagen, muscle, fat, and feathers) differs from tissue spacings in mammals. Linear mixing models were then used to estimate diet based on new tissue spacing data and isotope data from archaeological bird bone collagen. These results were compared to previous studies of Arctic paleodiet. Zooarchaeological analysis of the avifaunal remains suggests that Pre-Dorset and Dorset groups on the Knud Peninsula preferentially hunted eider ducks, and birds were heavily processed for human consumption. Bird bones were also used in tool production. Stable isotope analysis of various tissues from ducks fed a controlled diet indicates that avian tissue spacings differ from those of mammals by up to 2‰, especially for stable carbon isotopes. Results from the stable isotope analysis of archaeological avifaunal samples demonstrate that birds have variable isotopic signatures that reflect dietary preferences, migratory routes, and reproductive strategies. Finally, the inclusion of avian-specific tissue spacing values and isotopic signatures for birds and their eggs in linear mixing models for Arctic hunter-gatherers demonstrates that birds and their eggs can be detected isotopically and that these additions can alter our interpretations of the role of birds and eggs in human paleodiet.

description: We quantify the potential for testing MOdified Newtonian Dynamics (MOND) with LISA Pathfinder (LPF), should a saddle point flyby be incorporated into the mission. We forecast the expected signal to noise ratio (SNR) for a variety of instrument noise models and trajectories past the saddle. For standard theoretical parameters the SNR reaches middle to high double figures even with modest assumptions about instrument performance and saddle approach. Obvious concerns, like systematics arising from LPF self-gravity, or the Newtonian background, are examined and shown not to be a problem. We also investigate the impact of a negative observational result upon the free-function determining the theory. We demonstrate that, if Newton's gravitational constant is constrained not be re-normalized by more than a few percent, only contrived MONDian free-functions would survive a negative result. There are exceptions, e.g. free-functions not asymptoting to 1 in the Newtonian limit, but rather diverging or asymptoting to zero (depending on their mother relativistic MONDian theory). Finally, we scan the structure of all proposed relativistic MONDian theories, and classify them with regards to their non-relativistic limit, finding three broad cases (with a few sub-cases depending on the form of the free function). It is appears that only the Einstein-Aether formulation, and the sub-cases where the free-function does not asymptote to 1 in other theories, would survive a negative result without resorting to "designer" free-functions.

description: The Cluny Fortified Village site (EePf-1) is the only known fortified village on the Canadian Plains. Archaeologically, the main cultural layer indicates patterns that are not commonly seen elsewhere on the Plains. Many of the larger questions about the people of this site are largely left unanswered, and the experimentation of different methods can offer new perspectives to complement the ongoing excavations at the site. Phytolith analysis has not been extensively explored at the site and can offer perspectives about the presence of natural and cultural signatures. Phytolith analysis has been combined with charcoal analysis and used to explore queries regarding cultural signatures as well as the present and past environment. Three preliminary projects provided opportunities to refine the appropriate laboratory methods for this project which ultimately improved the overall phytolith counts. Over the course of the 2015 and 2016 field seasons at the Cluny Fortified Village matrix samples from both occupational layers were sampled as well as several hearth and non-hearth features. In 2016, a larger scaled survey was conducted to collect samples from the area surrounding the site. These samples form the natural control that will be compared against cultural samples. The Old Women’s Phase site of DkPi-2 (Junction Site) was used as a contemporary cultural comparative. Both phytolith and charcoal sample analyzed were provided by Lifeways of Canada Ltd. A total of 71 phytolith samples and 70 charcoal samples were analyzed. Results are indicative of a stable grassland that has seen little change over the past 300 years. Poaceae grasses are dominant amongst the datasets, with other families contributing less. Through examining phytoliths of productive plants in an archaeological context, a possible cultural signature may be presence.

description: There are few direct measurements of ICM velocity structure, despite its importance for understanding clusters. We present a detailed analysis of the velocity structure of the Centaurus cluster using XMM-Newton observations. Using a new EPIC-pn energy scale calibration, which uses the Cu Ka instrumental line as reference, we are able to obtain velocity measurements with uncertainties down to $Δv \sim 79$ km/s. We create 2D spectral maps for the velocity, metallicity, temperature, density, entropy and pressure with an spatial resolution of 0.25'. We have found that the velocity structure of the ICM is similar to the velocity structure of the main galaxies while the cold fronts are likely moving in a plane perpendicular to our line of sight with low velocity. Finally, we have found a contribution from the kinetic component of <25\% to the total energetic budget for radius $>30$ kpc.

description: The presence of microbunching instabilities due to the compression of high-brightness electron beams at existing and future X-ray free-electron lasers (FELs) results in restrictions on the attainable lasing performance and renders beam imaging with optical transition radiation impossible. The instability can be suppressed by introducing additional energy spread, i.e., "heating" the electron beam, as demonstrated by the successful operation of the laser heater system at the Linac Coherent Light Source. The increased energy spread is typically tolerable for self-amplified spontaneous emission FELs but limits the effectiveness of advanced FEL schemes such as seeding. In this paper, we present a reversible electron beam heating system based on two transverse deflecting radio-frequency structures (TDSs) up and downstream of a magnetic bunch compressor chicane. The additional energy spread is introduced in the first TDS, which suppresses the microbunching instability, and then is eliminated in the second TDS. We show the feasibility of the microbunching gain suppression based on calculations and simulations including the effects of coherent synchrotron radiation. Acceptable electron beam and radio-frequency jitter are identified, and inherent options for diagnostics and on-line monitoring of the electron beam's longitudinal phase space are discussed.
