description: A polypyridyl ruthenium(II) complex with hydroxyquinoline-derived ligand has been synthesized and characterized. The ability to act as telomeric quadruplex inducer and stabilizer, and quadruplex-binding properties of the complex have been evaluated by absorption and emission analyses, fluorescent intercalator displacement (FID) titrations, circular dichroism (CD) spectroscopy, polymerase chain reaction (PCR) stop assay, color reaction studies, fluorescence resonance energy transfer (FRET) melting assay, Job plot, and molecular modeling. Observations revealed that the complex could well induce and stabilize the formation of antiparallel G-quadruplex of telomeric DNA in the presence or absence of metal cations, and showed superior G-quadruplex selectivity over duplex DNA with remarkable ΔTm value of 18.0 °C even at 50-fold excessive supplies of calf thymus (ct) DNA. The complex exhibited high interaction affinity of 2.56 × 106 M−1 with G-quadruplex DNA and evident luminescence enhancements of 3.1 and 4.2 times for quadruplex binding in Na+ and K+ buffer, respectively. In addition, the 1:1 [quadruplex]/[complex] binding mode ratio was determined. The results suggest that the complex can be developed as potential anticancer reagent through binding and stabilization of G-quadruplex DNA.

description: The lack of baseline estimates of air-sea CO₂ exchange in Arctic and sub-Arctic regions represents a major shortfall in our ability to understand how climate change may affect CO₂ fluxes at high latitude. The 2005 ArcticNet cruise of Hudson Bay provided a rare comprehensive oceanographic survey of one such region. Ship-based observations of sea­surface fugacity of CO₂ (fCO₂sw) were made at 56 locations between September 15 and October 26, and were found to range from 259µ atm in Hudson Strait to 425µ atm at the entrance to James Bay. Strong relationships between fCO₂sw and river discharge were identified, with coastal waters observed to be supersaturated in fCO₂sw with respect to the atmosphere (and thus a source of CO₂), while off-shore waters were undersaturated (thus a sink). High correlation of fCO₂sw with salinity, sea surface temperature (SST), and colored dissolved organic matter (CDOM) suggest that thermodynamic effects and possibly the oxidation of riverine carbon were driving supersaturation in the coastal zone. To expand the spatial and temporal domain of the study, a remote sensing approach was applied. Predictive algorithms for fCO₂sw were created from relationships with CDOM and SST; variables which can be measured from satellite remote sensing platforms. A SST­ fCO₂sw algorithm was used with monthly maps of SST obtained from the MODIS aqua sensor to extrapolate fCO₂sw in Hudson Bay for the 2005 ice-free season (August-October). Gas transfer velocities were estimated using twice-daily QuikSCAT wind retrievals, and by using a bulk aerodynamic approach the monthly flux of CO₂ in Hudson Bay was calculated. The results of these calculations revealed that Hudson Bay acts as a source of CO₂ during August and September (4.10 and 5.29 mmol m⁻² day⁻¹, respectively), but reverts to a sink of CO₂ in October as the water temperature cools (-5.83 mmol⁻² day⁻¹). By integrating over the spatial extent of Hudson Bay and the 92 day open-water season, a positive flux of 0.93 TgC was estimated. This result is in contrast to most Arctic or sub-Arctic continental shelf seas, where usually strong absorptions of CO₂ are observed. It is hypothesized that this difference is related to the strong influence of river discharge. Future studies are necessary to constrain fluxes in Hudson Bay over an annual cycle and to determine the oceanographic controls on CO₂ flux. However, this study is significant since it represents the first-ever examination of air-sea CO₂ exchange in Hudson Bay.
title: Why is the business school system in perpetual crisis? Explaining the legitimacy paradox
Creators: name: Aldridge, Jacqueline
Publisher: name: University of Kent
Year: 2023

description: This thesis explores the paradox of the one-hundred-year legitimacy crisis of the Business School. Although it dominates global higher education, the business school system has always struggled to establish legitimacy with multiple stakeholders across multiple dimensions. Given its ostensible success, evidence for this crisis is found primarily in influential published sources. However, crisis narratives are polarised between advocating solutions to specific problems or challenging the Business School's existence. Few authors explore the complexities of the problems or their structural origins. In this thesis, I address this gap by asking why the Business School is negated by the wider academic community, how its internal academic community frames the problems over time and how equivalent academic entities maintain their legitimacy. I answer the first two questions through rhetorical analyses of textual corpora drawn from scholarly literatures. I use a critical realist framework to identify causal mechanisms that may explain the persistence of a multi-faceted legitimacy crisis. I then combine these findings with a range of theoretical perspectives from different fields to create a model of occupational higher education. This model identifies a number of pathways that the business school system could follow to establish and sustain legitimacy. However, I conclude that stakeholders of the contemporary business school system may not have the appetite for the necessary structural change, given the likely systemic and personal consequences. I also suggest that scapegoating the Business School serves the interests of the wider academic workforce and may prove an insurmountable obstacle to Business School legitimacy building.

description: For a Riemannian manifold $(M,g)$ which is isometric to the Euclidean space outside of a compact set, and whose trapped set has Liouville measure zero, we prove Weyl type asymptotics for the scattering phase with remainder depending on the classical escape rate and the maximal expansion rate. For Axiom A geodesic flows, this gives a polynomial improvement over the known remainders. We also show that the remainder can be bounded above by the number of resonances in some neighbourhoods of the real axis, and provide similar asymptotics for hyperbolic quotients using the Selberg zeta function.

description: Cloud computing offers a pool of various cloud resources, including scalable computing instances, database instances, storage, network bandwidth, etc. which are delivered to customers in an on-demand or reserved manner. In recent years, cloud computing has become a major enablement for businesses and researchers to reduce the deployment costs by externalizing their resources in the cloud environment. Achieving an optimal set of cloud resources for web application deployment among different public cloud providers is a challenge that becomes more difficult when cloud customers tend to optimize both deployment costs and Quality of Service (QoS). Furthermore, due to lack of understanding of the pricing model and the cloud IaaS, a customer may pay more than necessary or may not fully utilize the purchased resources. In this thesis, to tackle these challenges, first, a QoS-aware cost optimization algorithm is proposed that finds the most cost-effective cloud resources for web application deployment. The proposed algorithm maps the minimum required resources for the web application to minimize the deployment costs according to the price model set by the cloud providers. In the next stage, a multi-cloud datacenters cost optimization algorithm is proposed to distribute the cloud resources in different cloud datacenters to improve the web application availability and maintain QoS for geographically distributed user demands. To solve the cloud-based deployment problem from the cloud customer’s point of view, it is vital to balance the two conflicting objectives of deployment costs and QoS performance. Therefore, in this research, a multi-objective optimization algorithm is proposed that minimizes cost and maximizes QoS performance simultaneously by providing a balanced trade-off. Finally, a hybrid method to allocate resources according to the dynamic user demands is developed which includes the reservation and dynamic provision phases. The total deployment cost of each phase is formulated as the optimization objective and a stochastic optimization approach is developed to model the uncertainties in the user demands as random variables.
A Comparative Study of Divergence Control Algorithms

Subjects: Computer science

description: This paper evaluates and compares the performance of two-phase locking divergence control (2PLDC) and optimistic divergence control (ODC) algorithms using a comprehensive centralized database simulation model. We examine a system with multiclass workloads in which on-line update transactions and long-duration queries progress based on epsilon serializability (ESR). Our results demonstrate that significant performance enhancements can be achieved with a non-zero tolerable inconsistency (ϵ-spec). With sufficient ϵ-spec and limited system resources, both algorithms achieve comparable performance. However, with low resource contention, ODC performs significantly better than 2PLDC. Moreover, given a small ϵ-spec, ODC returns more accurate results on the committed queries then 2PLDC.

A syncronous coefficient of drag alteration (SCODA) based technique for sequence specific enrichment of nucleic acids
Creators: name: Thompson, Jason Donald
Publisher: name: University of British Columbia
Year: 2011

description: Sequence based enrichment of nucleic acids is a critical enabling component of future nucleic acid detection methods in many fields including detection of nucleic acid tumor biomarkers in body fluids, non-invasive prenatal detection of fetal genetic abnormalities, and detection of pathogenic microorganisms. In many cases the problem of detecting the nucleic acid biomarker of interest is confounded by the presence of a large excess of nucleic acid sequences that may differ from the sequence of interest by only a single base. Consequently, existing methods are limited in sensitivity and amount of starting material to avoid overwhelming the detection methods with background nucleic acids. This limits their usefulness to a small number of applications. Techniques for enrichment of specific sequences rely on hybridization, and are generally not capable of enriching for low abundance sequences by more than 10 fold, a limit imposed by the thermodynamics of hybridization. In this dissertation I present a technique for sequence enrichment of nucleic acids based on synchronous coefficient of drag alteration (SCODA), which enables sequence specific enrichment of nucleic acids from sample volumes greater than 100 μL, with concurrent concentration of the nucleic acids to volumes appropriate for PCR detection (<10 μL). We have demonstrated that this technique is capable of at least 10,000 fold enrichment of target sequences with respect to contaminating sequences differing by a single base. We have additionally shown that this technique is capable of at least 100 fold enrichment of a target sequence with a single methylated cytosine residue in a background of unmethylated targets of identical sequence by exploiting the small difference in binding energy of a methylated target to its complementary probe compared to an unmethylated target. To our knowledge this is the most specific hybridization based sequence enrichment scheme in existence, and this is the first demonstration of hybridization based enrichment of unmodified methylated DNA. Although some technical challenges must be overcome before this method will become a tool appropriate for routine laboratory use, we believe that the challenges are not insurmountable, and this method has the potential to enable routine analysis of low abundance nucleic acids.
Flow Trees: A Lower Bound Computation Tool with Applications to Rearrangeable Multihop Lightwave Network Optimization

Subjects: Computer science

description: This paper presents a new method for computing the lower bounds for multihop network design problems which is particularly well suited to optical networks. More specifically, given N stations each with d transceivers and pairwise average traffic values of the stations, the method provides a lower bound for the combined problem of finding optimum (i) allocation of wavelengths to the stations to determine a configuration, and (ii) routing of the traffic on this configuration while minimizing congestion - defined as the maximum flow assigned on any link. The lower bounds can be computed in time polynomial in the network size. Consequently, the results in this work yield a tool which can be used in (i) evaluating the quality of heuristic design algorithms, and (ii) determining a termination criteria during minimization. The lower bound computation is based on first building flow trees to find a lower bound on the total flow, and then distributing the total flow over the links to minimize the congestion.

description: In the run-up to the American Civil War, vigilantism became a common phenomenon in the new West, with ad hoc mining tribunals giving way to permanent committees intent on policing the rapidly urbanising cities of the California gold fields. The earliest example of this organised, violent activism in the region came in the form of San Francisco’s Vigilance Committee, which operated during the summer of 1851. This study argues that this iteration of the Vigilance Committee, despite being an important milestone in Western antebellum vigilantism, has been misrepresented and mischaracterised by its earliest documenters. A preoccupation with legacy, and chiefly an attempt to establish a sympathetic, celebratory one, resulted in the Committee’s story being reconstructed for that purpose. The first two chapters of this thesis outline and explore realities of two core arguments of that reconstruction: first, the reality of the supposed crime wave that justified the Committee’s formation; second, that the Committee was efficient, effective, and uncorrupted. This feeds into a third chapter that argues the Committee’s historical value in spite of its superfluous formation and questionable utility. By positioning the vigilantes’ story within a nascent antebellum trend of vigilantism as activism in the West, this study holds that the Committee’s curious story never needed embellishment or justification to be an important turning point in San Franciscan, Californian, and pre-Civil War history.
Performance Evaluation of an Integrated Access Scheme in a Satellite Communication Channel

description: A method for realizing a circuit and packet integrated access scheme in a satellite communication channel is considered. Two kinds of terminals are assumed, namely, bursty terminals for handling bursty traffic and heavily loaded terminals for long-holdingtime message traffic. In this method, the channel frame is divided into two subframes: one is for bursty terminals, and the other is for heavily loaded terminals. The subframe for heavily loaded terminals is further divided into two subchannels, a reservation subchannel (consisting of small slots) and a message subchannel. The bursty terminals transmit their packets in their dedicated subframes on the slotted ALOHA protocol. The heavily loaded terminal having a message transmits, first of all, a reservation packet in a randomly selected small slot of the reservation subchannel to reserve slots in the coming message subchannels. One slot in the same position of each of the succeeding message subchannels is reserved for the terminal until the end-of-use flag, transmitted from the terminal, is received by the satellite. Mean transmission delays for both kinds of traffic in this method are analytically obtained. We show that there exists an optimal frame length which minimizes mean transmission delay for one kind of traffic while keeping mean transmission delay for the other kind under some permissible value.

description: We study the bound states of a three-dimensional Holstein polaron near various kinds of single impurities, using the momentum average approximation. We show that the electron-phonon coupling is responsible for a strong renormalization of the impurity potential, resulting in an effective potential with significant retardation effects, which describes essential physics ignored by "instantaneous" approximations. The accuracy of our approximation is gauged by comparison with results from Diagrammatic Monte Carlo for the case of an impurity that modifies the on-site energy of the electron. We also discuss impurities that modify the local strength of the electron-phonon coupling, as well as isotope substitutions that change both the electron-phonon coupling and the phonon frequency, and contrast and highlight the difference between these cases.

description: The purpose of this thesis is to design and implement a new protocol for Black Box tool enveloping, in the context of the Oz Process Centered Environment, as an auxiliary mechanism that deals with additional families of tools, whose character prevents a thoroughly satisfactory service by the current encapsulation method. We mean to address interpretive and query systems, multi-user collaborative and non- collaborative tools, and programs that allow incremental binding of parameters after start-up and storing of intermediate and/or partial results. Our goal is to support a greater amount of interaction between multiple human operators, the tools and the environment, in the context of complex software development and management tasks. During the realization of this project, we introduced several concepts related to integration of Commercial Off-The-Shelf tools into Software Development Environments: an approach based on multiple enveloping protocols, a categorizaton of tools according to their multi-tasking and multi-user capabilities, the ideas of loose wrapping (as opposed to the usual tight wrapping) and of persistent tools (with respect to the duration of a single task), and a functional extension of some intrinsically single-user applications to a (limited) form of collaboration.

The validity of purchasing power parity over the last century

Publisher: name: University of Calgary
Year: 2007

description: Bibliography: p. 64-73
description: This thesis tests the validity of purchasing power parity (PPP), a theory which summarizes the equilibrium relationship between the exchange rate and relative price levels. In general, previous studies have not found support for PPP in the short run, yet mixed results occurred when PPP was tested over long time periods. This thesis examines the behavior of real exchange rates for a group of 23 OECD countries over 100 years. For the first time, Rescaled Range Analysis, which consists of the Hurst exponent and the modified R/S statistic, is employed to detect the long memory in real exchange rate series. Overall, the results do not provide evidence of stationarity or long memory in real exchange rates, which leads to the rejection of PPP. To ensure the robustness of the results, conventional unit root and stationarity tests were applied, with the same disappointing results.

description: At very high densities, electrons react with protons to form neutron rich matter. This material is central to many fundamental questions in nuclear physics and astrophysics. Moreover, neutron rich matter is being studied with an extraordinary variety of new tools such as the Facility for Rare Isotope Beams (FRIB) and the Laser Interferometer Gravitational Wave Observatory (LIGO). We describe the Lead Radius Experiment (PREX) that uses parity violating electron scattering to measure the neutron radius in $^{208}$Pb. This has important implications for neutron stars and their crusts. We discuss X-ray observations of neutron star radii. These also have important implications for neutron rich matter. Gravitational waves (GW) open a new window on neutron rich matter. They come from sources such as neutron star mergers, rotating neutron star mountains, and collective r-mode oscillations. Using large scale molecular dynamics simulations, we find neutron star crust to be very strong. It can support mountains on rotating neutron stars large enough to generate detectable gravitational waves. We believe that combing astronomical observations using photons, GW, and neutrinos, with laboratory experiments on nuclei, heavy ion collisions, and radioactive beams will fundamentally advance our knowledge of compact objects in the heavens, the dense phases of QCD, the origin of the elements, and of neutron rich matter.

Brain networks involved in source monitoring in schizophrenia
Creators: name: Metzak, Paul
Publisher: name: University of British Columbia
Year: 2011

description: Schizophrenia is characterized by cognitive deficits in many domains. One of the domains in which these deficits are commonly found is in self-other source monitoring. Source monitoring refers to the set of processes by which individuals recall the conditions and contextual details surrounding the encoding of a memory episode, and self-other source monitoring specifically involves differentiating between actions performed by oneself versus those performed by another person. In this study, the goal was to investigate the neural basis of self-other source monitoring, and to discover how this neural activity differs in schizophrenia. The results of this study indicate that schizophrenia patients and healthy control subjects utilize essentially the same neural network for self-other source monitoring, and that this network involves brain areas that have been described as belonging to the task-positive and task-negative networks. Multiple statistical methods were used to analyze this dataset in order to provide a comprehensive set of results, as well as to determine the agreement between them. Although differences exist between the methods employed herein, in both the matrices that are used as input, and the mathematical operations performed on them, the results suggest that all the methods identified a common signal in the data.

Enveloping Sophisticated Tools into Process-Centered Environments

description: We present a tool integration strategy based on enveloping pre-existing tools without source code modifications or recompilation, and without assuming an extension language, application programming interface, or any other special capabilities on the part of the tool. This Black Box enveloping (or wrapping) idea has existed for a long time, but was previously restricted to relatively simple tools. We describe the design and implementation of, and experimentation with, a new Black Box enveloping facility intended for sophisticated tools --- with particular concern for the emerging class of groupware applications.
Stereo in the Presence of Specular Reflection

description: The problem of accurate depth estimation using stereo in the presence of specular reflection is addressed. Specular reflection, a fundamental and ubiquitous reflection mechanism, is viewpoint dependent and can cause large intensity differences at corresponding points, resulting in significant depth errors. We analyze the physics of specular reflection and the geometry of stereopsis which led us to a relationship between stereo vergence, surface roughness, and the likelihood of a correct match. Given a lower bound on surface roughness, an optimal binocular stereo configuration can be determined which maximizes precision in depth estimation despite specular reflection. However, surface roughness is difficult to estimate in unstructured environments. Therefore, trinocular configurations, independent of surface roughness, are determined such that at each scene point visible to all sensors, at least one stereo pair can compute produce depth. We have developed a simple algorithm to reconstruct depth from the multiple view images. Experiments with real surfaces confirm the viability of our approach. A key feature of this approach is that we do not seek to eliminate or avoid specular reflection, but rather minimize its effect on stereo matching.

description: This paper studies long-term contracts for experimentation in a principal-agent setting with adverse selection about the agent’s ability (pre-contractual hidden information), dynamic moral hazard, and private learning about project quality. We show that profit maximization by the principal generally leads to under-experimentation by an agent of low ability, even though there would be no distortion in the absence of either adverse selection or moral hazard. The structure of optimal contracts is shaped by a variety of considerations including dynamic agency costs and the possibility of post-contractual hidden information about project quality. We derive two explicit menus of contracts that can be used to implement the second best solution: “bonus contracts” and “clawback contracts”. Both feature history-contingent dynamic streams of transfers.

description: We address an issue: would the cosmological scale factor be a locally oscillating quantity? This problem is examined in the framework of two classical 1+1-dimensional models: the first one is a string against a curved background, and the second one is an inhomogeneous Bianchi I model. For the string model, it is shown that there exist the gauge and the initial condition providing an oscillation of scale factor against a slowly evolving background, which is not affected by such an oscillation "at the mean". For the inhomogeneous Bianchi I model with the conformal time gauge, an initially homogeneous scale factor can become inhomogeneous and undergo the nonlinear oscillations. As is shown these nonlinear oscillations can be treated as a nonlinear gauge wave.

description: The high-energy tail of the distribution of solute-solvent interaction energies is poorly characterized for condensed systems, but this tail region is of principal interest in determining the excess free energy of the solute. We introduce external fields centered on the solute to modulate the short-range repulsive interaction between the solute and solvent. This regularizes the binding energy distribution and makes it easy to calculate the free energy of the solute with the field. Together with the work done to apply the field in the presence and absence of the solute, we calculate the excess chemical potential of the solute. We present the formal development of this idea and apply it to study liquid water.

description: A number of computational imaging techniques have been introduced to improve image quality by increasing light throughput. These techniques use optical coding to measure a stronger signal level. However, the performance of these techniques is limited by the decoding step, which amplifies noise. While it is well understood that optical coding can increase performance at low light levels, little is known about the quantitative performance advantage of computational imaging in general settings. In this paper, we derive the performance bounds for various computational imaging techniques. We then discuss the implications of these bounds for several real-world scenarios (illumination conditions, scene properties and sensor noise characteristics). Our results show that computational imaging techniques provide a significant performance advantage in a surprisingly small set of real world settings. These results can be readily used by practitioners to design the most suitable imaging systems given the application at hand.

description: With proper physical mechanisms of energy and momentum input from around the centre of a self-gravitating polytropic gas sphere, a central spherical "void" or "cavity" or "bubble" of very much less mass contents may emerge and then dynamically expand into a variety of surrounding more massive gas envelopes with or without shocks. We explore self-similar evolution of a self-gravitating polytropic hydrodynamic flow of spherical symmetry with such an expanding "void" embedded around the center. The void boundary supporting a massive envelope represents a pressure-balanced contact discontinuity where drastic changes in mass density and temperature occur. We obtain numerical void solutions that can cross the sonic critical surface either smoothly or by shocks. Using the conventional polytropic equation of state, we construct global void solutions with shocks travelling into various envelopes including static polytropic sphere, outflow, inflow, breeze and contraction types. In the context of supernovae, we discuss the possible scenario of separating a central collapsing compact object from an outgoing gas envelope with a powerful void in dynamic expansion. Initially, a central bubble is carved out by an extremely powerful neutrinosphere. After the escape of neutrinos during the decoupling, the strong electromagnetic radiation field and/or electron-positron pair plasma continue to drive the cavity expansion. In a self-similar dynamic evolution, the pressure across the contact discontinuity decreases with time to a negligible level for a sufficiently long lapse and eventually, the gas envelope continues to expand by inertia. We describe model cases of polytropic index $γ=4/3-ε$ with $ε>0$ and discuss pertinent requirements to justify our proposed scenario.
