description: Vibrio cholerae is the causative agent of the pandemic disease Cholera. It uses a type 6 secretion system (T6SS) to aid its colonization and survival in both aquatic environments and host intestines. The T6SS is a molecular machine analogous to a spear gun, shooting a molecular spear through adjacent cell membranes, delivering proteins in the process. Use of the T6SS is energetically costly as it requires hundreds of protein subunits, and, between each round of firing, recycling of cellularly retained components requires energy while hundreds of secreted proteins must be regenerated. The T6SS provides a clear evolutionary benefit to V. cholerae under some conditions as it allows V. cholerae to outcompete other bacteria. However, some V. cholerae strains produce the T6SS when it does not provide a benefit, making it unclear how this is an evolutionarily viable strategy of controlling energetically costly T6SS production. In this thesis, I investigate two phenotypes observed in regulation of T6SS auxiliary clusters in V. cholerae. First, I characterized that downregulation of T6SS auxiliary clusters in strains with non-functional T6SS occurs due to accumulation of Hcp from lack of secretion. I then found that this Hcp accumulation results in Hcp interactions with the transcription factor VasH, reducing the ability of VasH to activate transcription from auxiliary T6SS clusters. This acts as a negative feedback loop with Hcp, a product of auxiliary clusters inhibiting its own expression through inhibitory interactions with VasH. This regulatory mechanism allows fine-tuning of levels of expression from T6SS auxiliary clusters to match the rate of T6SS firing, reducing the energy waste of overproducing in conditions with reduced rates of T6SS activity. I then characterized a method of post-transcriptional regulation that occurs in T6SS auxiliary clusters. Endoribonuclease cleavage of mRNA allows production of Hcp and VgrG at appropriate stoichiometric levels (50-100-Fold difference) despite being co-transcribed. Co-transcription facilitates reduction in stochastic noise that would occur if the two proteins were produced from separate promoters while maintaining appropriate expression levels, ensuring a consistent ratio between the two T6SS components. Overall, both described regulatory mechanisms provide insight into how V. cholerae efficiently produces its T6SS.

description: Robotic-assisted colorectal surgery is a novel minimally invasive approach to cancers of the rectum and rectosigmoid. Compared to the more established laparoscopic-assisted technique, the robotic platform offers three-dimensional visualization and greater degrees of instrument mobility. While the robotic technique has gained widespread use in the United States and Europe, implementation in Canada remains limited due to high costs. Although there is some evidence for improved robotic outcomes, there is minimal reporting of Canadian outcomes after robotic rectal and rectosigmoid cancer resection. Further, there is a paucity of economic evaluations informing the cost-effectiveness of robotic rectal cancer resection. We assessed clinicopathologic outcomes and surgeon learning curve associated with robotic-assisted rectal and rectosigmoid cancer resection in an Alberta setting. We then systematically reviewed existing economic evaluations on robotic-assisted colorectal surgery. Finally, we performed a cost-utility analysis to inform the robotic technology’s cost-effectiveness compared to the laparoscopic approach in rectal cancer care. Our Canadian outcomes study included 67 patients who underwent robotic-assisted rectal and rectosigmoid cancer resection in Alberta’s first robotic colorectal surgery program. We found that the Alberta clinicopathologic results are comparable to existing international studies despite surgeons in the Alberta program being robotic novices at the start of the series. Robotic operating time decreased significantly as surgeon experience increased. We found four economic evaluations in the literature reporting on cost-effectiveness of robotic-assisted colorectal surgery. Two studies found it to be cost-effective whereas the other two found the contrary. Due to significant inter-study heterogeneity and contradicting results, there is no definitive conclusion to robotic cost-effectiveness without further research. Our cost-utility analysis found that robotic-assisted rectal cancer surgeon is cost-effective compared to the laparoscopic approach at a Canadian cancer care-specific cost-effectiveness threshold of CAD $100,000, assuming high case volumes on the robot. The wider adoption of robotic technology in Canadian rectal cancer care should be considered at high volume centres.

description: Neutrophils are a vital component of the innate immune system and are among the first to respond to infections. Pseudomonas aeruginosa is an opportunistic pathogen which can cause severe pneumonia in immunocompromised and critically ill patients. Neutrophils are an important first line of defense in P. aeruginosa infections as evidenced by the life-threatening disease it can cause in neutropenic patients. P. aeruginosa can form biofilms, an extracellular matrix of largely composed of polysaccharides, which are proposed to interfere with host defenses during infection. However, there are knowledge gaps in understanding the precise mechanisms of interference with host immune responses. Understanding these gaps are important in order to understand disease pathogenesis and potentially refine treatment options. In this body of work, I investigate how P. aeruginosa biofilm components, PEL and PSL, impact host response. I discovered that the presence of PEL and PSL during P. aeruginosa pneumonia infection impacts sickness severity in the host; however, this was not due to neutrophil or pulmonary inflammation. Rather, our results challenge the concept of classical inflammation inducing sickness responses by implicating a previously unreported mechanism whereby sensory neurons (TRPV1+ nociceptors) directly mediate sickness severity and lethal hypothermia via neuronal expression of TLR4. Furthermore, I demonstrated that sickness severity is not a direct consequence of pro-inflammatory cytokines, rather it is caused by differential pathogen detection through TLR4 expression on TRPV1+ nociceptors. I acknowledge the importance of studying disease in males and females to determine the potential sex-based differences. Our results show differences in pneumonia severity and immune responses to P. aeruginosa only when PEL and PSL are produced. Thus, both neuro-immunity and sex of the host are important factors in mediating pneumonia severity and early immune responses to P. aeruginosa pneumonia.

description: We investigate evolution of quantum correlations in ensembles of two-qubit nuclear spin systems via nuclear magnetic resonance techniques. We use discord as a measure of quantum correlations and the Werner state as an explicit example. We first introduce different ways of measuring discord and geometric discord in two-qubit systems and then describe the following experimental studies: (a) We quantitatively measure discord for Werner-like states prepared using an entangling pulse sequence. An initial thermal state with zero discord is gradually and periodically transformed into a mixed state with maximum discord. The experimental and simulated behavior of rise and fall of discord agree fairly well. (b) We examine the efficiency of dynamical decoupling sequences in preserving quantum correlations. In our experimental setup, the dynamical decoupling sequences preserved the traceless parts of the density matrices at high fidelity. But they could not maintain the purity of the quantum states and so were unable to keep the discord from decaying. (c) We observe the evolution of discord for a singlet-triplet mixed state during a radio-frequency spin-lock. A simple relaxation model describes the evolution of discord, and the accompanying evolution of fidelity of the long-lived singlet state, reasonably well.

Parametrically prox-regular functions
Creators: name: Planiden, Chayne
Publisher: name: University of British Columbia
Year: 2013

description: Prox-regularity is a generalization of convexity that includes all lower-C² functions. Therefore, the study of prox-regular functions provides insight on a broad spectrum of important functions. Parametrically prox-regular (para-prox-regular) functions are a further extension of this family, produced by adding a parameter. Such functions have been shown to play a key role in understanding the stability of minimizers in optimization problems. This thesis discusses para-prox-regular functions in ℝn. We begin with some basic examples of para-prox-regular functions, and move on to the more complex examples of the convex and non-convex proximal averages. We develop an alternate representation of para-prox-regular functions, related to the monotonicity of an f-attentive ε-localization as was done for prox-regular functions [25]. Levy in [18] provided proof of one implication of this relationship; we provide a characterization. We analyze two common forms of parametrized functions that appear in optimization: finite parametrized sum of functions, and finite parametrized max of functions. The example of strongly amenable functions by Poliquin and Rockafellar [27] is given, and a relaxation of its necessary conditions is presented. Some open questions and directions of further research are stated.
Identification of Disinfection By-products from Chlorination and Bromination of Benzotriazole

Publisher: name: Science
Year: 2022
Subjects: subject: Health And Environmental Sciences

description: This thesis work aims to investigate the roles of benzotriazole (BTR) during the disinfection process in wastewater treatment plants (WWTPs). In recent years, increasing attention has been focused on emerging contaminants in surface waters due to their possible adverse health and environmental effects. BTR has been extensively used in versatile industrial and domestic applications. For instance, BTR is widely used in aircraft de-icing and anti-icing fluids. BTR is not well removed from the conventional WWTPs. It persists for long periods in the receiving environment (i.e., rivers, lakes) and causes adverse health effects of living organisms. Therefore, it is important to investigate the extent of BTR’s fate and transformation during the disinfection of wastewater effluent. First, chlorination (HOCl) and bromination (HOBr) of BTR was conducted at different molar ratios and pH conditions to identify possible chlorinated and brominated intermediates and products. The reaction progress was monitored using UV-Vis spectrophotometer at different time intervals. Ultra-pressure liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was employed to identify possible chloro- and bromo- BTR intermediates and products. N-chloro-BTR (N-Cl BTR) was identified during chlorination with HOCl to BTR (Cl/BTR) molar ratio of 10. Excess of HOBr to BTR (Br/BTR ? 10), however, produced two mono-, two di-, one tri-, one tetra-bromo BTRs, and unknown di-bromo compound (C2HN3Br2). Decreasing molar ratio decreased the number of intermediates and products formation. Both chlorination and bromination of BTR was pH-dependent; low pH favored the formation of chlorinated and brominated BTRs.Since N-halo BTR (N-Cl BTR and N-Br BTR) acts as an oxidant, it is not well understood the role of N-halo BTR on the formation of unregulated disinfectant by-products (DBPs) by reacting with natural organic matter. The last part of this work investigated the role of organic N-halamine (N-halo BTR) for formation of high-priority unregulated DBPs. A total of 30 high-priority DBPs were quantified using gas chromatography-tandem mass spectrometry (GC-MS/MS) to investigate potential DBP formation from reaction between N-halo BTR and secondary wastewater effluent (SWE). N-halo BTR/SWE samples formed unregulated DBPs, including haloacetonitriles (HANs), haloaldehydes (HALs), haloketones (HKTs), trihalomethanes (THMs), and halonitromethanes (HNMs).

description: ObjectiveTo determine whether and how often the required information to measure a set of previously developed key performance indicators (KPIs) was documented in data routinely collected in a Pediatric Rheumatology Clinic.MethodsA retrospective electronic chart review and administrative data analysis was conducted for a cohort of 140 patients with juvenile idiopathic arthritis (JIA) at a tertiary Pediatric Rheumatology Clinic between 2016-2020. Data was assessed as a binary variable indicating whether the required information was found. Documentation frequency for each KPI was assessed with counts and percentages of the number of times the required information was documented for each clinic visit. Compliance with the safety KPI definitions was assessed using administrative databases. ResultsAlthough data for each KPI were found in the cohort, documentation varied in frequency and consistency. Access to care and safety KPIs were documented more frequently than patient outcome KPIs. A joint assessment was documented at every visit for 95% of patients, 46% for an assessment of pain, and none for a physician’s global assessment of disease activity, an assessment of functional ability, or a composite disease activity measurement. Of the patients with documentation for waiting time for pediatric rheumatologist referral visit, 75% (n=24) had an eligible date documented. All of the patients who had a visit following their diagnosis date, had a visit within the first year of diagnosis and 78% of patients saw their rheumatologist at least once every year over their follow-up period. Tuberculosis screening was documented in 96% of the biologic patients. The first two years of eligible intervals documentation of laboratory monitoring for patients receiving methotrexate and leflunomide ranged from 76% to 90% after the first month. ConclusionAlthough the KPIs are feasible to measure in routinely collected data, there is an opportunity for improving the consistency of documentation. Having an active system of monitoring KPIs and tools to simplify measurement is a key step in the process toward improving patient outcomes. Streamlining the collection of KPI data can increase the likelihood of compliance. Next steps should involve replicating this study in various centres.

description: This article gives a study of the higher-dimensional Penrose transform between conformally invariant massless fields on space-time and cohomology classes on twistor space, where twistor space is defined to be the space of projective pure spinors of the conformal group. We focus on the 6-dimensional case in which twistor space is the six-quadric Q in CP^7 with a view to applications to the self-dual (0,2)-theory. We show how spinor-helicity momentum eigenstates have canonically defined distributional representatives on twistor space (a story that we extend to arbitrary dimension). These give an elementary proof of the surjectivity of the Penrose transform. We give a direct construction of the twistor transform between the two different representations of massless fields on twistor space (H^2 and H^3) in which the H^3s arise as obstructions to extending the H^2s off Q into CP^7. We also develop the theory of Sparling's `Ξ-transform', the analogous totally real split signature story based now on real integral geometry where cohomology no longer plays a role. We extend Sparling's Ξ-transform to all helicities and homogeneities on twistor space and show that it maps kernels and cokernels of conformally invariant powers of the ultrahyperbolic wave operator on twistor space to conformally invariant massless fields on space-time. This is proved by developing the 6-dimensional analogue of the half-Fourier transform between functions on twistor space and momentum space. We give a treatment of the elementary conformally invariant Φ^3 amplitude on twistor space and finish with a discussion of conformal field theories in twistor space.

description: We prove a lower bound for the first Steklov eigenvalue of embedded minimal hypersurfaces with free boundary in a compact $n$-dimensional manifold which has nonnegative Ricci curvature and strictly convex boundary. When $n=3$, this implies apriori area and curvature estimates for these minimal surfaces in terms of the geometry of the ambient manifold and the topology of the minimal surface. An important consequence of the estimate is a smooth compactness result for embedded minimal surfaces with free boundary when the topological type of these minimal surfaces is fixed.

description: The lattice Weinberg - Salam model at zero temperature is investigated numerically. We consider the model for the following values of the coupling constants: the Weinberg angle $θ_W \sim 30^o$, the fine structure constant $α\sim 1/150$, the Higgs mass $M_H \sim 150$ GeV. We find that the fluctuational region begins at the values of the cutoff $Λ$ above about 0.8 TeV. In this region the average distance between Nambu monopoles is close to their sizes. At $Λ> 1$ TeV the Nambu monopole currents percolate. Within the fluctuational region the considered definitions of the scalar field condensate give values that differ from the expected one $2 M_Z/g_z$. We consider the given results as an indication that the nonperturbative effects may be present in the Weinberg - Salam model at the large values of the cutoff. Our numerical results were obtained on the lattices of sizes up to $16^3\times 32$.

description: The notion of singular reduction modules, i.e., of singular modules of nonclassical (conditional) symmetry, of differential equations is introduced. It is shown that the derivation of nonclassical symmetries for differential equations can be improved by an in-depth prior study of the associated singular modules of vector fields. The form of differential functions and differential equations possessing parameterized families of singular modules is described up to point transformations. Singular cases of finding reduction modules are related to lowering the order of the corresponding reduced equations. As examples, singular reduction modules of evolution equations and second-order quasi-linear equations are studied. Reductions of differential equations to algebraic equations and to first-order ordinary differential equations are considered in detail within the framework proposed and are related to previous no-go results on nonclassical symmetries.

description: Over the past 20 years, steam-assisted gravity drainage (SAGD) has become one of the dominant methods for producing heavy oil and oil sands reservoirs. With the crash in the price of oil in late 2014 and again in early 2020 and the ever-increasing push for reductions of emissions, SAGD operators are facing a challenging future of reduced revenues and increased costs. The research documented in this thesis focuses on the development and deployment of a state-of-the-art production forecasting and optimization tool for SAGD operations, mAI (short for ‘my augmented intelligence’), which leverages recent advances in automation and machine learning to allow for faster and more efficient subsurface decision making in SAGD heavy oil operations in Saskatchewan, Canada. mAI helps find subsurface strategies that carefully optimize steam usage (which reduces operating costs and emissions) while increasing production (which increases revenue generation). Two real-world case studies are presented including an end-of-life field and a brand-new SAGD facility. In both cases, bespoke artificial intelligence solutions lead to remarkable improvement in both profitability and emissions. The full field start-up and ramp-up is shown to be the most successful in the province’s history. The limitations of this work are also discussed. In particular, the amount of time needed to develop methods that allow for many systems to work in conjunction, each solving a very narrow problem. Future work involves expanding the scope of mAI from Saskatchewan to Alberta and from the subsurface to surface optimizations, including pipelines, facilities, and logistics.

description: Energy technologies integrated with carbon capture contribute to energy production by lowering the environmental impact. Chemical looping combustion (CLC), as such technology, can produce energy from fossil fuels while capturing CO2. Improving the performance of Oxygen Carrier (OC) material is essential for the improvement of CLC technology. Understanding the effect of support material on OC performance is crucial to develop a framework for the selection of suitable support and an optimal design for OC. To develop such an understanding, the synergetic (atomic-level electronic) effects of support material, oxygen vacancy defects and their interplay on the performance of OC are investigated by Density Functional Theory. The effect of different reacting species on the OC performance is also investigated.In the first three parts of the thesis, NiO is considered as oxygen carrier, with TiO2 and MgO as supports, and H2 as fuel. Firstly, the results indicate that the electronic interaction of the TiO2 support with NiO lowers the energy of intermediate states and the energy of the reaction. The interplay between the electronic effect of TiO2 and the geometric effect of oxygen vacancy results in a more stable chemisorbed state, as the reaction proceeds. Secondly, it was found that by addition of an oxygen vacancy and change of hydrogen adsorption sites, the magnitude of H–Ni interaction increases, which results in the enhanced reactivity of NiO after O vacancy creation. Thirdly, by comparing the synergetic effect of TiO2 and MgO supports, it was found that adding a more electronegative support of TiO2 results in creating a more stable chemisorbed state. This shows that we can correlate the reactivity of OC with electronegativity as an atomic-scale property of the support to establish a framework for support material selection. In the last part of this study, the synergetic effect of reacting species on the performance of FeTiO3 oxygen carrier was investigated by deriving the micro-mechanisms and calculating the energetics of CH4 oxidation reaction and CO2, an unwanted reacting species, reduction reaction. The results explain the observed trend of drop in OC performance and syngas production due to the presence of CO2.

description: For Girls Who Dare to Dream is an African work of fiction in the form of short stories. This collection interweaves multiple genres and themes namely: African folklore, African futurism, the Weird and the Eerie, the African gothic, Realism and Magical Realism. The female protagonists in this collection are complex and multidimensional women and girls navigating different urban and rural spaces. Some of the characters in this collection live in an Island only inhabited by women while other characters are trapped in a house where they must adhere to the demands of someone or something they cannot see or name. Although the stories in this collection are not all interconnected, For Girls Who Dare to Dream aims to circulate freely between genres to dismantle the perceptions and expectations of African literature and Culture in Western media. The collection is followed by an exegesis titled “Shedding Beliefs: Challenging Reductive, Stereotyped Readings of African Literature” which argues that African literature is only perceived to be ‘real’ and accurate to the non-African reader if it depicts countries filled with despair and hopelessness. The exegesis analyses the works of two writers Leila Aboulela, Nadifa Mohammed and filmmaker Mati Diop to illustrate the ways in which writers and filmmakers including myself are challenging the stereotypical and reductive expectation of African literature and culture.

description: We present a new scheme for the general computation of cosmic propagators that allow to interpolate between standard perturbative results at low-k and their expected large-k resummed behavior. This scheme is applicable to any multi-point propagator and allows the matching of perturbative low-k calculations to any number of loops to their large-k behavior, and can potentially be applied in case of non-standard cosmological scenarios such as those with non-Gaussian initial conditions. The validity of our proposal is checked against previous prescriptions and measurements in numerical simulations showing a remarkably good agreement. Such a generic prescription for multi-point propagators provides the necessary building blocks for the computation of polyspectra in the context of the so-called Gamma-expansion introduced by Bernardeau et al. (2008). As a concrete application we present a consistent calculation of the matter bispectrum at one-loop order.

description: This study was aimed at exploring the experiences of Somali immigrant mothers caring for their children with autism spectrum disorder. Research questions were, (a) What are the experiences of Somali newcomer mothers who support their children with autism? (b) What is their understanding of autism? (c) What elements of support do these mothers perceive as helpful? (d) What challenges do these mothers face in accessing services? and, (e) How is the experience of mothering a child with autism perceived to affect settlement and integration processes? The study was informed by an intersectionality theoretical framework which promotes an understanding of human beings as shaped by the interaction of different social locations within contexts of connected systems and structures of power. The study incorporated qualitative inquiry, drawing on hermeneutic phenomenology as its methodological framework. Purposive sampling was used to recruit Somali immigrant mothers caring for their children with autism spectrum disorder in the Edmonton area. Nine mothers were interviewed, each with one child with autism (seven male children and two female children) ranging from Grades 2 to 12. Data were collected through individual, semistructured, in-depth interviews guided by preprepared open-ended questions and probes. Each interview was transcribed verbatim for data analysis. Data were analyzed using manual techniques with the assistance of NVivo qualitative data management and analysis software. Themes that emerged from the data were as follows: Overwhelming: ‘I didn’t know what autism was’; Responsibility: ‘No one understands my child’; Insufficient help: ‘Challenges finding supports’; School struggles: ‘Meeting my child’s educational needs’; Impeded settlement: ‘Unmet settlement and integration needs’; Faith as a resource: ‘Religion as a source of strength’; Mothers’ voices quelled: ‘Power imbalance’; and Discrimination: ‘Racism, ableism, and patriarchy’.Mothers provided heightened levels of caregiving with insufficient system-based supports. Research results add to the literature and increase our understanding of the experiences of Somali immigrant mothers caring for their children with autism. The study will inform practice and policy, family supports, and resource/support considerations.

description: Quantum computational algorithms exploit quantum mechanics to solve problems exponentially faster than the best classical algorithms. Shor's quantum algorithm for fast number factoring is a key example and the prime motivator in the international effort to realise a quantum computer. However, due to the substantial resource requirement, to date, there have been only four small-scale demonstrations. Here we address this resource demand and demonstrate a scalable version of Shor's algorithm in which the n qubit control register is replaced by a single qubit that is recycled n times: the total number of qubits is one third of that required in the standard protocol. Encoding the work register in higher-dimensional states, we implement a two-photon compiled algorithm to factor N=21. The algorithmic output is distinguishable from noise, in contrast to previous demonstrations. These results point to larger-scale implementations of Shor's algorithm by harnessing scalable resource reductions applicable to all physical architectures.

energy research

description: The researchers working in the project ZLE developed an “Open Science Declaration” committing their research activities to the standards of Open Science. Research within the ZLE will be built upon the idea of sharing scientific methods, data, and publications to improve research quality and make results accessible to the scientific and non-scientific communities.
 Members of the ZLE support the principles of Open Science as expressed by the Budapest Open Access Initiative, the Berlin Declaration, the Horizon 2020 Program, and the German Strategy for Open Access.
 Funded by the Ministry of Science and Culture of Lower Saxony, one of the major goals of the ZLE is to make energy research activities and its resources available for public use while preserving the intellectual property of all involved parties. This will strengthen the research in Lower Saxony by promotion and expansion of cooperation between science and industry on strategic sectors. Moreover, greater transparency in the use of public funds and in the development of research activities is enabled.

ABSTRACT: This research is focused on bodies’ administrative liability ex d. lgs. n. 231 del 2001 and ecclesiastical boards which are civilly recognized. In particular we examine Italian regulations suitable for the mentioned boards. As a consequence we try to find the limits of d. lgs. n. 231 del 2001 application’s. This legislative decree regulates bodies’ liability for unlawful administrative (but substantial penal) acts relating to offences. The provisions set out therein apply to corporate entities and companies and associations including those which are not bodies corporate. However, the decree do not mention any ecclesiastical boards which are civilly recognized.
KEYWORDS: Ecclesiastical boards which are civilly recognized; Personae iuridicae canonicae; d.lgs. n. 231 del 2001.
