description: Innovation in open teaching and learning has become increasingly attentive to the commercial potential for scaling up as witnessed by the growth of massive open online courses (MOOCs) since 2012 (Urrea, Reich, & Thille, 2017). This attention intensifies under conditions of austerity and disruption, as both educational institutions and their technology company partners search for new markets and new means of profitable operation, targeting learners locally and across the world to whom education can be delivered with maximum efficiency and minimum cost. Drafting open pedagogy into this effort is troubling and invites us to revisit poorly-cited open education theories from the 1970s (see Rolfe, 2016) in order to understand the ecologies that shape open learning in the present.

description: The capability of ordinary surfactants in solubilizing hydrophobic compounds can come to a limit, if the extension of a contaminant is too large. An attractive goal is the development of surfactants which can actively reduce the size of dirt. Because strong Lewis acids are known to catalyze both bond formation and cleavage, an integration into the surfactant's molecular framework is tempting. End-group functionalized hepta-dentate ligands, which coordinate to metal ions preventing deactivation by hydrolysis over a broad range of pH values while maintaining strong Lewis-acidity, are herein presented. After proof of amphiphilicity and surfactant characteristics, catalytic properties are investigated for different reactions including the cleavage of proteins. The compounds perform better than benchmark catalysts concerning the attack of unreactive amide bonds. A study with two Sc3+ species as the active site, one non-amphiphilic, the other one being surface-active, underlines the positive effect of surfactant properties for boosting catalytic efficiency.

description: We reanalyze the W-boson loop in the amplitude of the Higgs decay into two photons to show the absence of decoupling in the limit of massless W bosons, m_W --> 0. The Higgs coupling to longitudinal polarizations survive in this limit and generates a nonvanishing contribution in the $H\to γγ$ decay. This shows that the recent claim of decoupling by R. Gastmans, S.L. Wu, and T.T. Wu is incorrect, and the old calculations for the two photon decay well known in the literature are valid.

description: Kohlenstoffnanoröhren (CNTs) gelten als vielversprechendes Elektrodenmaterial für Energiespeichersysteme und wurden in der vorliegenden Dissertation im Anwendungsgebiet der Vanadium-Redox-Flow-Batterie hinsichtlich der elektrokatalytischen Aktivität und deren Abhängigkeit von strukturellen Eigenschaften untersucht. Zunächst werden unterschiedliche Funktionalisierungsmethoden zum Eintrag von Sauerstoff bzw. Stickstoff in das CNT-Gerüst dargelegt. Die dabei auftretenden Defekte und Änderungen in der Morphologie werden mit Hilfe von XPS, Raman-Spektroskopie, TEM und TGA analysiert. Schwerpunkt ist hierbei die Bestimmung der Oberflächenzusammensetzung und Aufschlüsselung der funktionellen Gruppen an der CNT-Oberfläche. Im zweiten Abschnitt werden elektrochemische Aktivität und Stabilität der modifizierten CNTs mittels Zyklovoltammetrie, elektrochemischer Rastermikroskopie und Polarisationskurven untersucht. Am Ende werden auftretende Korrelationen zwischen Sauerstoff- oder Stickstoff-Gehalt und der elektrokatalytischen Aktivität aufgezeigt.
description: Carbon nanotubes (CNTs) as promising electrode material for energy storage applications were investigated in this thesis for Vanadium-Redox-Flow-Battery setups concerning the electrocatalytic activity and their dependence on structural properties. At first various functionalization procedures incorporating oxygen and nitrogen atoms in the CNT structure are demonstrated. Occurring defects and changes in the morphology of the modified CNTs are characterized with XPS, Raman spectroscopy, TEM and TGA. On this occasion the main part of structural characterization focusses on the surface composition and the distinction of functional groups on the CNT surface. In the second part the electrochemical properties of modified CNTs including activity and stability are analyzed with cyclic voltammetry, scanning electrochemical microscopy and polarization curves. Appearing correlations between oxygen or nitrogen content and the electrocatalytic activity are pointed out at the end.

description: A wealth of information is hidden within unstructured text. This information is often best exploited in structured or relational form, which is suited for sophisticated query processing, for integration with relational databases, and for data mining. Current information extraction techniques extract relations from a text database by examining every document in the database, or use filters to select promising documents for extraction. The exhaustive scanning approach is not practical or even feasible for large databases, and the current filtering techniques require human involvement to maintain and to adapt to new databases and domains. We develop an automatic query-based technique to retrieve documents useful for the extraction of user-defined relations from large text databases, which can be adapted to new domains, databases, or target relations with minimal human effort. We report a thorough experimental evaluation over a large newspaper archive that shows that we significantly improve the efficiency of the extraction process by focusing only on promising documents.

description: Many studies show the sensitivity of our environment to manmade changes, especially the anthropogenic impact on atmospheric and hydrological processes. The effect on Solid Earth processes such as subsidence is less straightforward. Subsidence is usually slow and relates to the interplay of complex hydro-mechanical processes, thus making relations to atmospheric changes difficult to observe. In the Dead Sea (DS) region, however, climatic forcing is strong and over-use of fresh water is massive. An observation period of 3 years was thus sufficient to link the high evaporation (97 cm/year) and the subsequent drop of the Dead Sea lake level (− 110 cm/year), with high subsidence rates of the Earth’s surface (− 15 cm/year). Applying innovative Global Navigation Satellite System (GNSS) techniques, we are able to resolve this subsidence of the “Solid Earth” even on a monthly basis and show that it behaves synchronous to atmospheric and hydrological changes with a time lag of two months. We show that the amplitude and fluctuation period of ground deformation is related to poro-elastic hydro-mechanical soil response to lake level changes. This provides, to our knowledge, a first direct link between shore subsidence, lake-level drop and evaporation.

description: Die vorliegende Dissertationsschrift beschäftigt sich mit der Etablierung eines chemo-enzymatischen Verfahrens zur regiospezifischen und chemoselektiven C- und N-terminalen Modifizierung von Proteinen. Hierbei wurde die bereits etablierte Trypsiligase verwendet, um chemisch weiter modifizierbare Funktionalitäten auf enzymatischem Wege in Proteine einzubringen. Als Funktionalitäten dienten hierbei Azid-, Alkin-, Alken- oder Tetrazinderivate, die im Zuge einer bioorthogonalen Cycloadditionsreaktion entsprechend derivatisiert werden konnten. Somit konnte im Rahmen einer C-terminalen Modifikation ein Antikörperfragment mit Mertansin, einem Cytostatikum, versehen werden. Darüber hinaus konnte die Prolyl-cis-trans Isomerase Cyclophilin mit Hilfe dieses Verfahrens N-terminal mit einem Dansylfarbstoff versehen werden.
description: The present thesis deals with the establishment of a chemo-enzymatic method for the regiospecific and chemoselective C- and N-terminal modification of proteins. Here, the already established trypsiligase was used to introduce further chemically modifiable functionalities into proteins by enzymatic means. The functionalities used here were azide, alkyne, alkene or tetrazine derivatives which could be correspondingly derivatized in the course of a bioorthogonal cycloaddition reaction. Thus, in the context of a C-terminal modification, an antibody fragment could be provided with mertansine, a cytostatic agent. The prolyl cis-trans isomerase cyclophilin could be provided with a dansyl dye at the N-terminus using this method.
Regulatory mitigation of the adverse environmental effects of urban blasting
Creators: name: Loeb, Jeffrey Thomas
Publisher: name: University of British Columbia
Year: 2012

description: Blasting techniques and protective measures exist that can mitigate risks associated with flyrock and the nuisance of vibration, and overpressure. However, these are often misused or not used because there are no prescriptive regulatory requirements and typically, urban blasting guidelines do not exist. The relationship between the increasingly negative publicity that the urban blasting industry receives and the existing state of regulatory control on blasting in urban environments is presented. Specific research points include: 1. Incidents of flyrock, vibration and overpressure related to blasting operations in urban environments were investigated across Canada but with a focus in the province of British Columbia. 2. A comparison and evaluation of blasting regulatory control in Canada, United States and Australia are presented. 3. An analysis of incidents and complaints, complemented with the approaches used to regulate blasting was performed. 4. Provincial and municipal regulators, blasting contractors, and blasting consultants were interviewed to seek advice on practical amendments to Canadian regulations to mitigate the adverse environmental effects of urban blasting. At the provincial level, it is recommended that an amendment to WorkSafeBC’s Blasting Regulations Part 21.66 (1) to hold the blasting company, in addition to the blaster, responsible for flyrock incidents will reduce incidents. At the municipal level, it is suggested that a proposed harmonized blasting bylaw, that includes an education plan in the form of an informative pamphlet, will reduce the number of vibration, and overpressure complaints. This blasting bylaw coupled with delivery of the pamphlet should minimize (i) risk to a municipality, (ii) cost and time commitment to a municipality, (iii) complaints made by concerned residents, and (iv) adverse effects on blaster productivity.

description: Modern, powerful techniques for the residual analysis of spatial-temporal point process models are reviewed and compared. These methods are applied to California earthquake forecast models used in the Collaboratory for the Study of Earthquake Predictability (CSEP). Assessments of these earthquake forecasting models have previously been performed using simple, low-power means such as the L-test and N-test. We instead propose residual methods based on rescaling, thinning, superposition, weighted K-functions and deviance residuals. Rescaled residuals can be useful for assessing the overall fit of a model, but as with thinning and superposition, rescaling is generally impractical when the conditional intensity $λ$ is volatile. While residual thinning and superposition may be useful for identifying spatial locations where a model fits poorly, these methods have limited power when the modeled conditional intensity assumes extremely low or high values somewhere in the observation region, and this is commonly the case for earthquake forecasting models. A recently proposed hybrid method of thinning and superposition, called super-thinning, is a more powerful alternative.

Comparative Techno economic Analysis of Ammonia Electrosynthesis

Publisher: name: Schulich School of Engineering

Subjects: subject: Engineering--Chemical

description: Ammonia (NH3) is a valuable chemical that is used as fertilizer, antimicrobial agent, and household cleaner and is among the largest chemicals produced globally. Currently, the Haber-Bosch (H-B) process, which requires elevated pressure (~100 bar) and temperature (~450C), is used to produce the majority of NH3. The H-B generates large quantities (1500 kg-CO2/ton-NH3) of greenhouse gases (GHG), especially during the steam methane reforming process to produce hydrogen (H2) feedstock. There has been growing interest in alternative electrochemical processes for NH3 synthesis due to their modular design, reduced capital cost, and potential to reduce GHG emissions over that of the H-B process. In this thesis, six alternative NH3 electrosynthesis routes are analyzed from both economic and environmental aspects. Among the six routes, electrosynthesis of NH3 from N2 and H2O at room temperature is found to be the most economically compelling process (levelized cost ~$414/ton-NH3). Compared to a conventional H-B plant, electrosynthesis using electricity from clean sources could reduce CO2 emissions by 75-90%. Based on this analysis, we have estimated the target performance metrics that need to be achieved at scale to make the electrochemical NH3 synthesis route economically and environmentally viable. This analysis reveals that electrochemical processes have merit and potential to replace the H-B process if target performance parameters (current density higher than 400 mA/cm2, selectivity higher than 60%, energy efficiency higher than 50%, and overpotential lower than 1.5 V) are achieved. This analysis gives an early indication for the electrosynthesis route to be economically viable and environmentally sustainable as compared to the century-old H-B process.

description: An important component of any generation system is the mapping dictionary, a lexicon of elementary semantic expressions and corresponding natural language realizations. Typically, labor-intensive knowledge-based methods are used to construct the dictionary. We instead propose to acquire it automatically via a novel multiple-pass algorithm employing multiple-sequence alignment, a technique commonly used in bioinformatics. Crucially, our method lever-ages latent information contained in multi-parallel corpora --- datasets that supply several verbalizations of the corresponding semantics rather than just one.We used our techniques to generate natural language versions of computer-generated mathematical proofs, with good results on both a per-component and overall-output basis. For example, in evaluations involving a dozen human judges, our system produced output whose readability and faithfulness to the semantic input rivaled that of a traditional generation system.

description: This dissertation develops two and three-dimensional coupled electrostatic-mechanical models for RF MEMS switches. The electrostatic solution is obtained either by applying Laplace's equation in the homogenous regions and Gauss's law at the interface nodes or by applying Gauss's law in the whole regions. In case of applying Laplace's equation, a system of equations is generated and solved using the band matrix method, while in case of applying Gauss's law in the whole region an updating equation for the potential is generated then an efficient iterative technique is employed to compute it. The mechanical model is based on solving the mechanical equation that describes the movement of the switch's bridge either analytically or numerically. The interaction between the electrostatic and mechanical models is considered iteratively. The shape of the bridge, as a function of applied voltage, and the pull down voltage have been calculated and are found to be in close agreement with published measurement data for similar switches geometries. The models are implemented with a numerical simulation program (MATLAB). This thesis covers also the design and optimization aspects of RF MEMS switches using full-wave 3-D EM simulators. Two designs have been proposed. One is a pi-configuration MEMS switch for wideband and high-isolation applications. Second is a single-pole, three-throw switch. Both switches are designed on a high resistivity Si substrate and are based on fixed-fixed membrane architecture. An equivalent circuit model for each switch is proposed to describe the switch RF-performance very well. Additionally, a two-dimensional periodic and an L-shaped defected ground structures (DGS) in the coplanar waveguide technology are proposed. A criterion that determines the dependence of the equivalent circuit elements on the design parameters of the defect is demonstrated. The proposed DGS structures are efficient to design high-performance bandstop filters. All theoretical results are verified experimentally and results agree very well. Last, as an application for the DGS and MEMS switches, an RF MEMS reconfigurable DGS resonator is designed using a 2-D periodic DGS and RF MEMS switches to control the resonant frequency. A new equivalent circuit model for the resonator is proposed and the method to extract the circuit element values is derived as well. The proposed structure can be used in automotive and transceiver applications.

description: Dynamic modeling of spoken dialogue seeks to capture how interlocutors change their speech over the course of a conversation. Much work has focused on how speakers adapt or entrain to different aspects of one another’s speaking style. In this paper we focus on local aspects of this adaptation. We investigate the relationship between backchannels and the interlocutor utterances that precede them with respect to pitch. We demonstrate that the pitch of backchannels is more similar to the immediately preceding utterance than non-backchannels. This inter-speaker pitch relationship captures the same distinctions as more cumbersome intra-speaker relations, and supports the intuition that, in terms of pitch, such similarity may be one of the mechanisms by which backchannels are rendered ’unobtrusive’.

description: The differential event rate for direct detection of dark matter, both the time averaged and the modulated one due to the motion of the Earth, are discussed. The calculations focus on relatively light cold dark matter candidates (WIMP) and low energy transfers. It is shown that for sufficiently light WIMPs the extraction of relatively large nucleon cross sections is possible. Furthermore for some WIMP masses the modulation amplitude may change sign, meaning that, in such a case, the maximum rate may occur six months later than naively expected. This effect can be exploited to yield information about the mass of the dark matter candidate, if and when the observation of the modulation of the event rate is established.

description: In this paper, we introduce a new approach to dialect recognition that relies on context-dependent (CD) phonetic differences between dialects as well as phonotactics. Given a speech utterance, we obtain the phone sequence using a CD-phone recognizer. We then identify the most likely dialect of these CD-phones using SVM classifiers. Augmenting these phones with the output of these classifiers, we extract augmented phonotactic features which are subsequently given to a logistic regression classifier to obtain a dialect detection score. We test our approach on the task of detecting four Arabic dialects from 30s utterances. We compare our performance to two baselines, PRLM and GMM-UBM, as well as to our own improved version of GMM-UBM which employs fMLLR adaptation. Our approach performs significantly better than all three baselines at 5% absolute Equal Error Rate (EER). The overall EER of our system is 6%.

description: We investigate one technique to produce a summary of an original text without requiring its full semantic interpretation, but instead relying on a model of the topic progression in the text derived from lexical chains. We present a new algorithm to compute lexical chains in a text, merging several robust knowledge sources: the WordNet thesaurus, a part-of-speech tagger, shallow parser for the identification of nominal groups, and a segmentation algorithm. Summarization proceeds in four steps: the original text is segmented, lexical chains are constructed, strong chains are identified and significant sentences are extracted. We present in this paper empirical results on the identification of strong chains and of significant sentences. Preliminary results indicate that quality indicative summaries are produced. Pending problems are identified. Plans to address these short-comings are briefly presented.

description: Native-like perception of intonational prominence is important for spoken language competency. Non-native speakers may have trouble interpreting prosodic variation in a second language like English, where intonational variation can critically influence utterance semantics. By identifying types of prosody non-native learners find difficult to perceive, we can improve our ability to teach L2 speakers a language. In this paper we present results of a perception study in which Mandarin speakers with knowledge of English were tested on their ability to identify prosodic prominence in English in a variety of contexts. Through this analysis we identify particular contexts which make it difficult for Mandarin speakers to recognize pitch accent in English.

This is the maximal possible length of such a sequence on this surface which has Grothendieck group Z^11+Z/5. In particular, the result answers Kuznetsov's Nonvanishing Conjecture, which concerns Hochschild homology of an admissible subcategory, in the negative. The sequence carries a symmetry when interpreted in terms of the root lattice of the simple Lie algebra of type E_8. We also produce explicit nonzero objects in the (right) orthogonal to the exceptional sequence.

Model Justifying Existence of 33 million Gods

description: Beyond the grasp of our understanding lie enigmatic forces, whose presence is felt and measured, yet their origins remain elusive and mysterious. Despite our inability to fathom them, we cannot refute their existence. This article discusses the possibility of the existence of 33 million gods or more in Hinduism, which is often associated with polytheism. The article cites literature that explores how energy can be transformed from one form to another, and how special shapes can be used to efficiently isolate energy. The article also discusses the use of mantras and how they generate certain frequencies that can help in various aspects of life. The article proposes a model that suggests that the energy generated by people, which is converted into sound energy, can be conserved in an isolated room and can act as a reservoir of energy. It is argued that this energy can be the basis for the existence of many gods in Hindu mythology, and that the architecture of temples and the use of mantras can contribute to the conservation and concentration of this energy.

description: We examine the role of prosody in cueing a scale of negative  meanings associated with the use of whatever. The analysis of  a corpus of elicited examples shows that the more negative  the token, the more likely it is to have an additional pitch  accent, extended duration, and expanded pitch range on the first syllable. These findings are analyzed as a link between  pragmatic meaning and the strength of the prosodic boundary between the first two syllables (what#ever). The results of
perception experiments show that the prosody of whatever itself is a systematic cue for the degree of negative  connotation associated with the utterance in which whatever occurs. Potential applications of this result for spoken  dialogue systems and synthesis of emotional speech are discussed.

description: Considerable recent attention has focussed on the prospects to use the cosmic microwave background (CMB) trispectrum to probe the physics of the early universe. Here we evaluate the probability distribution function (PDF) for the standard estimator tau_nle for the amplitude tau_nl of the CMB trispectrum both for the null-hypothesis (i.e., for Gaussian maps with tau_nl = 0) and for maps with a non-vanishing trispectrum (|tau_nl|>0). We find these PDFs to be highly non-Gaussian in both cases. We also evaluate the variance with which the trispectrum amplitude can be measured, , as a function of its underlying value, tau_nl. We find a strong dependence of this variance on tau_nl. We also find that the variance does not, given the highly non-Gaussian nature of the PDF, effectively characterize the distribution. Detailed knowledge of these PDFs will therefore be imperative in order to properly interpret the implications of any given trispectrum measurement. For example, if a CMB experiment with a maximum multipole of lmax = 1500 (such as the Planck satellite) measures tau_nle = 0 then at the 95% confidence our calculations show that we can conclude tau_nl < 1005; assuming a Gaussian PDF but with the correct tau_nl-dependent variance we would incorrectly conclude tau_nl < 4225; further neglecting the tau_nl-dependence in the variance we would incorrectly conclude tau_nl < 361.

description: In this paper, we introduce a new approach to dialect recognition that relies on context-dependent (CD) phonetic differences between dialects as well as phonotactics. Given a speech utterance, we obtain the phone sequence using a CD-phone recognizer. We then identify the most likely dialect of these CD-phones using SVM classifiers. Augmenting these phones with the output of these classifiers, we extract augmented phonotactic features which are subsequently given to a logistic regression classifier to obtain a dialect detection score. We test our approach on the task of detecting four Arabic dialects from 30s utterances. We compare our performance to two baselines, PRLM and GMM-UBM, as well as to our own improved version of GMM-UBM which employs fMLLR adaptation. Our approach performs significantly better than all three baselines at 5% absolute Equal Error Rate (EER). The overall EER of our system is 6%.

description: Background: The variety of medical documentation often leads to incompatible data elements that impede data integration between institutions. A common approach to standardize and distribute metadata definitions are ISO/IEC 11179 norm-compliant metadata repositories with top-down standardization. To the best of our knowledge, however, it is not yet common practice to reuse the content of publicly accessible metadata repositories for creation of case report forms or routine documentation. We suggest an alternative concept called pragmatic metadata repository, which enables a community-driven bottom-up approach for agreeing on data collection models. A pragmatic metadata repository collects real-world documentation and considers frequent metadata definitions as high quality with potential for reuse. Methods: We implemented a pragmatic metadata repository proof of concept application and filled it with medical forms from the Portal of Medical Data Models. We applied this prototype in two use cases to demonstrate its capabilities for reusing metadata: first, integration into a study editor for the suggestion of data elements and, second, metadata synchronization between two institutions. Moreover, we evaluated the emergence of bottom-up standards in the prototype and two medical data managers assessed their quality for 24 medical concepts. Results: The resulting prototype contained 466,569 unique metadata definitions. Integration into the study editor led to a reuse of 1836 items and item groups. During the metadata synchronization, semantic codes of 4608 data elements were transferred. Our evaluation revealed that for less complex medical concepts weak bottom-up standards could be established. However, more diverse disease-related concepts showed no convergence of data elements due to an enormous heterogeneity of metadata. The survey showed fair agreement (Kalpha = 0.50, 95% CI 0.43–0.56) for good item quality of bottom-up standards. Conclusions: We demonstrated the feasibility of the pragmatic metadata repository concept for medical documentation. Applications of the prototype in two use cases suggest that it facilitates the reuse of data elements. Our evaluation showed that bottom-up standardization based on a large collection of real-world metadata can yield useful results. The proposed concept shall not replace existing top-down approaches, rather it complements them by showing what is commonly used in the community to guide other researchers.

description: Psychotrope Medikamente (PM) werden häufig zur Kontrolle von neuropsychiatrischen Symptomen (NPS) bei Demenz eingesetzt, obwohl die mangelhafte Wirksamkeit und schwere unerwünschte Wirkungen bekannt sind. Ziel der Arbeit war es, eine Gesamtschau über die Verschreibungshäufigkeiten verschiedener PM und Antidementiva bei älteren (≥ 65 J.) Menschen mit Demenz (MmD) zu erhalten, Stichproben aus 8 europäischen Ländern (DE, EE, ES, EN, FI, FR, NL, SE) sowie zwei Pflegesettings (häusliche Pflege, Pflegeheim) zu vergleichen und verschreibungsassoziierte Faktoren zu ermitteln. Hierzu wurden die Daten des europäischen Projekts RightTimePlaceCare einer Sekundärdatenanalyse unterzogen. PM werden MmD durchgehend häufig verschrieben. In keinem der untersuchten Länder und Settings lassen sich an internationalen Leitlinien orientierte Verschreibungspraktiken ausmachen. Es besteht dringender Bedarf kritisch-abwägende Verordnungsstrategien und nicht-pharmakologische Behandlungsansätze zu etablieren.
description: Despite being knowingly ineffective in treating neuropsychiatric symptoms (NPS) psychotropic drugs (PD) are being widely used to treat NPS in people with dementia. The aim of this study was to get an overview over the prescription rate of PD and antidementives in elderly (≥ 65 y) people with dementia and compare these rates and associative factors between eight European countries (DE, EE, ES, EN, FI, FR, NL, SE) in domestic and nursing home settings. The data of the RightTimePlaceCare study were secondary analyzed. PD are commonly prescribed to people with dementia. None of the investigated countries followed international and national guidelines regarding prescribing PM to people with dementia. There is an urgent need to establish a more restrictive rate of prescribing PD and establishing the already known and proven non pharmaceutical treatment options.

description: We examine BACKCHANNEL-INVITING CUES — distinct prosodic, acoustic and lexical events in the speaker’s speech that tend to precede a short response produced by the interlocutor to convey continued attention — in the Columbia Games Corpus, a large corpus of task-oriented dialogues. We show that the likelihood of occurrence of a backchannel increases quadratically with the number of cues conjointly displayed by the speaker. Our results are important for improving the coordination of conversational turns in interactive voice-response systems, so that systems can produce backchannels in appropriate places, and so that they can elicit backchannels from users in expected places.

description: Recently a new picture has been developed for examining Wilson lines, and the corresponding anomalous dimensions which govern their renormalization properties. By making a particular coordinate transform, the calculation of the cusp anomalous dimension in QED or QCD can be related to the energy of a pair of static charges in Euclidean Anti-de-Sitter (AdS) space. This paper shows how the same picture can be used to describe Wilson lines in quantum gravity. We show how the relevant cusp anomalous dimension (which has recently been shown to be one loop exact) can be obtained using the Newtonian limit of General Relativity. We also show how both the QED and gravity cases emerge as special cases of a general formulation, and that a continuous parameter exists which interpolates between them. The results may be useful in examining the relations between gauge and gravity theories.

description: Cataloguers apply subject headings at the time they catalogue an item. As such, newer, contemporary terms used now to describe Indigenous Peoples and cultures differ from older, historical terminology of the past. This chapter analyses appropriate contemporary and historical controlled vocabulary including Canadian Subject Headings (CSH) and indexes for case law from 1892, as well as the legal literature indexes used in Canadian legal research. Changes in library subject headings and legal index taxonomy reflect changes in social norms, database practices, legal definitions, and various jurisdictions of Indigenous Peoples, including those located in Arctic Canada. Vernacular changes for subject headings were faster to shift for the collective term describing Indigenous Peoples in Arctic Canada, Inuit who were originally called Eskimo, when compared with other Aboriginal populations, notably First Nations, originally called Indian, and Métis. Contemporary researchers of Inuit Peoples and culture are encouraged to adapt search strategies that reflect both historical and contemporary terminology to effectively retrieve relevant database results across time even when outdated search terms must be used.

Shear stress and fouling control in hollow fiber membrane systems under different gas sparging conditions
Creators: name: Ye, Dongying
Publisher: name: University of British Columbia

description: The shear stress created by gas sparging has been widely recognized as a controlling factor in the fouling of submerged membrane systems. Effective gas sparging can significantly reduce the fouling and improve the membrane performance. Several factors, such as membrane module configuration, gas sparging tank configuration, gas sparging pattern and temperature, affect the hydrodynamic conditions around the membrane. Chan et al. (2011) reported that different types of shear profiles exist inside the submerged hollow fiber membrane module, and the different types of shear conditions have different effects on fouling control. In this thesis, the relationship between the shear stress generated by conventional sparging and a novel sparging approach on fouling control were studied. The results indicate that, to achieve the similar fouling control (fouling rate), only a quarter of energy (i.e air flow rate) input was required for the novel slug bubble sparger, compared to the conventional coarse bubble sparger.
