description: We prove that, given a function $f$ in the Nevanlinna class $N$ and a positive integer $n$, there exist $g\in N$ and $h\in BMOA$ such that $f^{(n)}=gh^{(n)}$. We may choose $g$ to be zero-free, so it follows that the zero sets for the class $N^{(n)}:=\{f^{(n)}: f\in N\}$ are the same as those for $BMOA^{(n)}$. Furthermore, while the set of all products $gh^{(n)}$ (with $g$ and $h$ as above) is strictly larger than $N^{(n)}$, we show that the gap is not too large, at least when $n=1$. Precisely speaking, the class $\{gh': g\in N, h\in BMOA\}$ turns out to be the smallest ideal space containing $\{f': f\in N\}$, where "ideal" means invariant under multiplication by $H^\infty$ functions. Similar results are established for the Smirnov class $N^+$.

Cognitive functioning in bipolar disorder : the influence of sex
Creators: name: Popuri, Swetha
Publisher: name: University of British Columbia
Year: 2012

description: Following a wave of similar research conducted in samples with schizophrenia, there has been a recent surge of studies investigating sex differences in the phenomenology of bipolar disorder (BD). These studies have almost exclusively focused on sex differences in course and clinical presentation. As compared with male BD patients, women with BD have increased likelihood of experiencing rapid cycling, mixed mania, suicidal ideation, and a medical or psychiatric comorbidity. However, in addition to its characteristic affective disturbance, the phenomenology of BD is associated with significant and persistent cognitive impairment. There is evidence to support that sexual dimorphisms, the basis of sex differences in cognitive functioning, are altered in BD. Additionally, it has been found that healthy patterns of cognitive sex differences are disrupted in schizophrenia, a closely related illness to BD. Despite this evidence, there have been few studies that have investigated the influence of sex on cognitive functioning in BD; the results that are available are both scant and contradictory. In order to clarify whether sex influences cognitive functioning in BD, 66 patients with BD-I disorder and 105 matched healthy controls were tested on a broad battery of neuropychological tests. As patients used in this sample were tested immediately proceeding symptomatic remission from their first-manic episode, this experimental design is poised to assess sex differences in cognitive functioning early in the course of BD. Overall, unlike in schizophrenia, healthy patterns of cognitive sex differences are intact early in the course of BD. To supplement and contextualize the study presented above, a large portion of this thesis is dedicated to providing literature reviews of the following topics: sex differences in the clinical phenomenology of BD, cognitive impairment in BD, sex differences in cognitive impairment and their neurobiological underpinnings in healthy samples.

description: Global change is driving declines in insect biodiversity, with widespread consequences for ecosystem function. Climate change and invasive species are key global change factors, but the ways in which they alter pollination are poorly understood in many systems. Camas meadows occur in the southwestern-most areas of Canada, where they support high floral and pollinator diversity, yet we know little about the pollination ecology of these meadows, let alone how they are impacted by aspects of global change. My objectives in this thesis were to evaluate evidence that camas meadows are experiencing impacts related to climate change and plant invasions. I used a pollen limitation experiment conducted across an elevation gradient to evaluate whether variation in climate generates phenological asynchrony between camas and its pollinators, and used plant-pollinator network analysis to examine whether introduced plants were driving changes in pollination networks. I found that there was no evidence for phenological asynchrony, though camas reproduction was slightly limited by pollen at low elevations, while overall seed production declined as camas approached its elevational limit. Introduced species did not alter network structure, but when removed from networks they had come to dominate, networks were less able to resist further species loss. This suggests that if maintaining pollination is desired, invasive species management decisions should consider the risks associated with losing the floral resources they seek to control. My results describe a system which in its current state, appears robust to the aspects of global change examined (i.e., phenological disturbance and plant invasion) but may be sensitive to further disruption, particularly the removal of abundant introduced plants that pollinators have come to rely upon.

description: Pairing plays a central role in nuclear systems. The simplest model for the pairing is the constant-pairing Hamiltonian. The aim of the present paper is to include the continuum single particle level density in the constant pairing Hamiltonian and to make a comparison between the approximate BCS and the exact Richardson solutions. The continuum is introduced by using the continuum single particle level density. It is shown that the continuum makes an important contribution to the pairing parameter even in those case when the continuum is weakly populated. It is shown that while the approximate BCS solution depends on the model space the exact Richardson solution does not.

description: Being Queer: LGBTQ History, Social Movements and Cultural Evolution Throughout Time in North America is a comprehensive paper that draws on the history of LGBTQ movements and social/cultural acceptance throughout time in North America starting with the Stonewall Riots of 1969. This paper examines such topics as the abovementioned Stonewall Riots, to the Canadian decriminalization/recriminalization of 1969, followed by homosexuality within the Canadian Military, religion, and homosexuality to LGBTQ students’ lives within the Canadian education system and, finally, pride semiotics. This paper found that while many important steps have been taken forward with the likes of the Stonewall Riots and the elimination of the ban on homosexuals within the Canadian Military, to the ordination of LGBTQ ministers within the United Church of Canada, we see a step taken back when it comes to LGBTQ students and the education system within Canada. Being Queer: LGBTQ History, Social Movements and Cultural Evolution Throughout Time in North America will take you on a historical and social ride throughout the LGBTQ communities relatively short, but strong fight for justice, acceptance, and freedom.

Our system is a $\sim$400 $μ$m-diameter planar crystal of several hundred $^9$Be$^+$ ions exhibiting complex drumhead modes in the confining potential of a Penning trap. Exploiting precise control over the $^9$Be$^+$ valence electron spins, we apply a homogeneous spin-dependent optical dipole force to excite arbitrary transverse modes with an effective wavelength approaching the interparticle spacing ($\sim$20 \nolinebreak$μ$m). Center-of-mass displacements below 1 nm are detected via entanglement of spin and motional degrees of freedom.

description: Most modern encryption schemes provide security contingent on one or more conjected but unproven computational hardness assumptions, implying that future algorithmic and technological advances might render existing ciphertexts insecure. The security guarantees of the venerable one-time pad (OTP) encryption scheme, by contrast, are information-theoretic and wholly unconditioned on unproven assumptions. Yet, despite the allure of ``unconditional'' security, sampling and managing the required randomness is so fraught that practitioners rarely employ OTP encryption in the wild---even in scenarios where long-term secrecy is paramount. Randy is an architecture and protocol suite that provides passphrase-authenticated and OTP-encrypted sockets suitable for communicating securely in ultrahigh-stakes adversarial environments where the adversary is assumed to be computationally unbounded. The Randy architecture centers around a shared randomness pool stored on a securely deletable storage device. This thesis aims to enhance the security and reliability of Randy's model through a comprehensive analysis. The existing model is thoroughly examined to identify weaknesses and vulnerabilities, which serve as the foundation for further improvements. To address these identified weaknesses, a secure and reliable synchronization scheme is proposed to ensure the security of the cryptosystem. Additionally, we introduce various techniques to manage and reduce randomness exhaustion in Randy. These techniques aim to improve the availability of the system by preserving the padding materials. Finally, we implement our design as a Linux kernel module that allows existing applications to seamlessly use Randy to provide unconditionally secure mutual authentication, message integrity, and secrecy for all messages. This implementation showcases the practicality of the model and highlights its security and functionality features. We analyze the security of our design and present empirical measurements from a prototype implementation thereof.
Predicting the Side Effects of Antiseizure Medications Using Machine Learning Models

description: With over 20 anti-seizure medications (ASMs), identifying the ideal drug is often imprecise and time-consuming. Developing predictive models to expedite optimal drug selection is challenging due to the minimal differences in efficacy among adult patients with epilepsy. However, side-effects vary considerably between medications, and are one of the main reasons for discontinuation of ASM treatment. The aim was to (1) assess the prognostic utility of high- dimensional data such as genetic features with clinical features to predict ASM discontinuation, and (2) determine the optimal regression/machine learning model for predicting ASM discontinuation. This retrospective cohort study included 4,853 exposures to any ASM, and 624 patients exposed to valproic acid (VPA) from the RAISE-GENIC study during the years 2006-2020. The predicted outcome was defined as ASM discontinuation due to any side-effect reported by the patient. Clinical features included age of onset, patient age, sex, comorbidities, seizure type, EEG variables, and imaging variables. Network analysis of mRNA expression data from VPA-exposed neurons derived from control induced pluripotent stem cells (iPSCs) was leveraged to extract exome sequencing and genome-wide single nucleotide polymorphism data. Features were selected for model inclusion based on relevance as determined by the ReliefF algorithm. Penalized logistic regression, support vector machine, random forest, and k-nearest neighbor models were trained on the normalized bootstrapped dataset and model quality was assessed using stratified 10-fold cross validation. Models with only clinical and combined clinical and genetic features were compared by quantitative as well as visual discrimination and calibration metrics. The results showed that the best performing model was the penalized logistic regression using the VPA dataset with genetic and clinical features. The accuracy was 0.75 [95% confidence interval 0.74-0.76], area under the receiver operating characteristic curve was 0.66 [0.66-0.67], Brier score was 0.20 [0.19-0.21], sensitivity was 0.42 [0.41-0.42], and specificity 0.82 [0.82-0.83]. Machine learning using clinical and genetic features can moderately predict treatment-ending side- effects to VPA with moderate performance, discrimination, and calibration. If these results can be validated and improved upon, decision tools can be incorporated into clinical routines, simplifying drug prescriptions, saving time, and improving patient quality of life.
Child care subsidies and child development : how four mothers story their experiences of their child(ren)'s development
Creators: name: Philion-Hunter, Sophia Lynne
Publisher: name: University of British Columbia
Year: 2012

description: This study’s purpose was to allow space for the voice of mothers in the realm of child care subsidy and child development research. Four Canadian mothers storied their experiences of their child(ren)’s development during a time in which they lacked child care subsidies. Each participant participated in a semi-structured interview designed to invoke narratives relating to their experience of their child(ren)’s development. Though each of the participants’ stories was analyzed individually, a cross-sectional analysis revealed common themes which spanned across each of their stories. These themes included a desire for a community, a sense of struggle, feelings of guilt, and changes. The mothers shared, through their narratives, that each perceived lack of child care subsidies as negatively affecting their child (ren)’s development. Implications of the study’s findings on social work practice at various levels of intervention were discussed, as well as recommendations for future research inquiries.

description: Gluinos that result in classic large missing transverse momentum signatures at the LHC have been excluded by 2011 searches if they are lighter than around 800 GeV. This adds to the tension between experiment and supersymmetric solutions of the naturalness problem, since the gluino is required to be light if the electroweak scale is to be natural. Here, we examine natural scenarios where supersymmetry is present, but was hidden from 2011 searches due to violation of R-parity and the absence of a large missing transverse momentum signature. Naturalness suggests that third generation states should dominate gluino decays and we argue that this leads to a generic signature in the form of same-sign, flavour-ambivalent leptons, without large missing transverse momentum. As a result, searches in this channel are able to cover a broad range of scenarios with some generality and one should seek gluinos that decay in this way with masses below a TeV. We encourage the LHC experiments to tailor a search for supersymmetry in this form. We consider a specific case that is good at hiding: baryon number violation, and estimate that the most constraining existing search from 2011 data implies a lower bound on the gluino mass of 550 GeV.

description: All living organisms must maintain accurate functioning and propagation of their genetic information. This is under persistent threat from DNA damaging events arising from cellular processes or exposure to DNA damaging agents. Amongst the most toxic forms of DNA damage are DNA double-strand breaks (DSBs). When unresolved or misrepaired DSBs can cause chromosomal breakages, fusions and chromosomal loss that drives cell death or genomic instability, which are hallmarks and drivers of cancer. The homologous recombination repair (HRR) pathway is an essential process that maintains genomic stability through the accurate repair of DSBs. RAD51 is the eukaryotic HRR recombinase that promotes HRR by assembling onto ssDNA to form nucleoprotein filaments and catalyses key HRR steps of strand invasion and homology search in the sister chromatid. A large number of accessory factors and RAD51 binding proteins, with inherited mutations in many of these predisposing to cancer, regulate the activities of RAD51 and the RAD51 filament to promote or inhibit HRR. The proper balance between pro- and anti-recombination factors is clearly essential to execute HRR only when necessary, in the correct cellular context. Despite this, there is a lack of high-resolution structures of RAD51 in complex with its protein partners, leading to large gaps in knowledge about structure-based mechanisms for RAD51 regulation in HRR. Here, I developed purification protocols and biochemical assays to quantify the activities of RAD51, which when applied in the context of RAD51 interactors will inform on the mechanistic basis for how they interact with and regulate RAD51 and RAD51 nucleoprotein filaments. I used these assays to study the interaction of RAD51AP1 with RAD51 and investigated a potential novel RAD51 interaction site within RAD51AP1. Finally, the reagents and protocols I developed, in addition to new methodologies, were used to investigate RAD51 interactions with other RAD51 regulatory proteins and the impact of small molecule inhibitors on Ku biochemistry.

description: The purpose of the present study was to examine associations between sleep patterns (sleep duration, sleep schedule regularity, sleep quality) and academic achievement (reading, writing, mathematics, overall achievement) in healthy, typically developing children who are just beginning formal education (i.e., grades 1 and 2). The study sample included 63 children, each with a participating parent. One week of parent-report sleep diary was used to assess children’s sleep duration and sleep schedule regularity, and the Children’s Sleep Wake Scale was used to assess sleep quality. Academic achievement was assessed using the Woodcock-Johnson IV Tests of Achievement (WJ-IV ACH). Poorer sleep patterns were not associated with academic decrements in any of the areas assessed, possibly due to our restrictive sample which comprised of children who could all be classified as good sleepers. Sleep duration had weak associations with reading and writing achievement such that as sleep duration decreased, achievement in reading and writing increased. These findings might be explained by an extension of the neural efficiency theory (i.e., more efficient daytime and nighttime processing/learning in shorter sleepers), the explanation that more time awake allows for additional learning, or the explanation that the children who slept longer did so to make up for less restorative sleep. Alternatively, other unidentified variables might account for the weak relationships seen. The study’s findings suggest that in a sample of grade 1 and 2 children sleeping adequate amounts, more sleep is not necessarily better in terms of academic learning. Future researchers are encouraged to continue to utilize more narrowly defined age groupings and strict health screening criteria to determine if these preliminary results can be replicated and if the same associations hold true for children at other stages of development.

description: Batteries as energy storage and conversion technologies, especially redox flow batteries (RFBs), have gained momentum in electric grids. The state-of-the-art RFB uses vanadium-based raw materials for their electrolytes; hence, they are called vanadium redox flow batteries, VRFB. While VRFB performance is well studied, their sluggish kinetics and precipitation issues still need to be addressed. In chapter 4 of this thesis, a raw material for VRFB, vanadium pentoxide V2O5, is studied. The studies involve long-term solubility monitoring, electrochemical screening, and spectral studies. V2O5 long-term solubility increased by adding a 5% volume of hydrochloric acid or methanesulfonic acid. Its electrochemistry performance also improved. A three-fold increase was observed in the diffusion coefficient of the ion VO2+ (formed from dissolving V2O5 in acid) and of the kinetic rate constant of the electron transfer process. Electrochemistry and spectral data proved the mechanism of the improvement. The additives provide extra protons for the dissolution of V2O5. The -OH groups or -CH3SO3- anions in methanesulfonic acid increase the solution’s wettability on the carbon electrode surface. The Cl- anions in hydrochloric acid form coordinated complexes with the dissolved vanadium ions, reducing the chance for clustering and precipitating. In chapter 5 of this thesis, RFB performance is studied. The V2O5-based solution with HCl additive is chosen as the positive electrolyte. An organic quinone solution, made from anthraquinone-2,6-disulfonate sodium (AQDS 2,6) dissolved in sulfuric acid, is chosen as the negative electrolyte. To facilitate the use of a hybrid inorganic – organic ‘vanadium || organic quinone’ cell, a silica gel separator is employed. The silica gel separator is made by dispersing silica into an acidic solution, which is identical to the solutions used to dissolve V2O5 or AQDS-2,6. The full cell has a capacity of 4 AhL-1, energy efficiency of 81.4%, and capacity retention of 97% after 500 cycles. Its voltage losses were predicted from the previous electrochemistry screening studies and analyzed from the full cell data. The reactions were confirmed using spectral data. The results demonstrate the potential for this system to be used in next-generation RFBs for energy storage applications.

description: This work seeks to more fully characterize how the representation of English vowels changes with increasing sound level in the frequency following response (FFR) of normal-hearing adult subjects. It further seeks to help inform the design of brain-computer interfaces (BCI) that exploit the FFR for hearing aid (HA) applications. The results of three studies are presented, followed by a theoretical examination of the potential BCI space as it relates to HA design. The first study examines how the representation of a long vowel changes with level in normal hearing subjects. The second study examines how the representation of four short vowels changes with level in normal hearing subjects. The third study utilizes machine learning techniques to automatically classify the FFRs captured in the second study. Based in-part on the findings from these three studies, potential avenues to pursue with respect to the utilization of the FFR in the automated fitting of HAs are proposed. The results of the first two studies suggest that the FFR to vowel stimuli presented at levels in the typical speech range provide robust and differentiable representations of both envelope and temporal fine structure cues present in the stimuli in both the time and frequency domains. The envelope FFR at the fundamental frequency (F0) was generally not monotonic-increasing with level increases. The growth of the harmonics of F0 in the envelope FFR were consistent indicators of level-related effects, and the harmonics related to the first and second formants were also consistent indicators of level effects. The third study indicates that common machine-learning classification algorithms are able to exploit features extracted from the FFR, both in the time and frequency domains, in order to accurately predict both vowel and level classes among responses. This has positive implications for future work regarding BCI-based approaches to HA fitting, where controlling for clarity and loudness are important considerations.

description: Fluctuation-enhanced sensing comprises the analysis of the stochastic component of the sensor signal and the utilization of the microscopic dynamics of the interaction between the agent and the sensor. We study the relationship between the measurement time window and the statistical error of the measurement data in the simplest case, when the output is the mean-square value of the stochastic signal. This situation is relevant at any practical case when the time window is finite, for example, when a sampling of the output of a fluctuation-enhanced array takes place; or a single sensor's activation (temperature, etc) is stepped up; or a single sensor's output is monitored by sampling subsequently in different frequency windows. Our study provides a lower limit of the relative error versus data window size with different types of power density spectra: white noise, 1/f (flicker, pink) noise, and 1/f^2 (red) noise spectra.

description: We determine the homogeneous Kähler diffeomorphism $FC$ which expresses the Kähler two-form on the Siegel-Jacobi ball $\mc{D}^J_n=\C^n\times \mc{D}_n$ as the sum of the Kähler two-form on $\C^n$ and the one on the Siegel ball $\mc{D}_n$. The classical motion and quantum evolution on $\mc{D}^J_n$ determined by a hermitian linear Hamiltonian in the generators of the Jacobi group $G^J_n=H_n\rtimes\text{Sp}(n,\R)_{\C}$ are described by a matrix Riccati equation on $\mc{D}_n$ and a linear first order differential equation in $z\in\C^n$, with coefficients depending also on $W\in\mc{D}_n$. $H_n$ denotes the $(2n+1)$-dimensional Heisenberg group. The system of linear differential equations attached to the matrix Riccati equation is a linear Hamiltonian system on $\mc{D}_n$. When the transform $FC:(η,W)\rightarrow (z,W)$ is applied, the first order differential equation in the variable $η=(\un-W\bar{W})^{-1}(z+W\bar{z})\in\C^n$ becomes decoupled from the motion on the Siegel ball. Similar considerations are presented for the Siegel-Jacobi upper half plane $\mc{X}^J_n=\C^n\times\mc{X}_n$, where $\mc{X}_n$ denotes the Siegel upper half plane.

description: To unravel the geologic sequence of events leading to the current configuration of Jurassic sediments of the Poseidon and Crown gas fields, Browse Basin, North West Shelf (NWS), Australia, a multi-variate, fully integrated workflow was developed. Basins undergoing extensional tectonics are often associated with igneous intrusions, volcanic tuffs, or basalt flows, these high amplitude features can resemble gas-filled sandstones or carbonate reefs in reflection seismic data. Basaltic intrusions are present throughout the Mid-Late Jurassic interval that contains reservoir-quality sandstones in the study area. This work will complement reservoir characterization studies required to support multi- trillion cubic feet (tcf.) of liquified natural gas (LNG) exports and associated carbon capture projects on the NWS. The study outlines the steps in workflow creation and evaluation of effectiveness. A seismic-stratigraphic framework was built to understand the tectonic influence on Jurassic strata. Within the framework, a multi-attribute, hierarchical seismic facies classification process, correlated to the seismic signature of wellbore lithologies, defines Seismic Cluster Facies (SCF). These were used in interpreting paleogeography and major geologic event timing.
News Media and the Military: Portraying and Responding to Right-Wing Extremism in the Canadian Armed Forces

description: In 2019 a Canadian Armed Forces (CAF) reservist was found to have been recruiting fellow reservists into a neo-Nazi paramilitary group known as The Base. The news of this event was reported in national headlines and an investigation into allegations of extremist recruitment was conducted by the CAF. While concerns of discrimination and racism within the military are not new, for instance, the scandal known as the Somalia Affair from the early 1990s involved allegations of racism within the military. The finding that the CAF was used to recruit members into right-wing extremist (RWE) groups was alarming. Traditional news media is vital to reporting and investigating stories, yet how stories are presented to the public can impact where people might stand on certain issues. News reports on RWE in the military could lead to diminished trust between the public and the CAF and could be damaging to the CAF’s reputation. This thesis explores how the Canadian news media portrays RWE in the CAF, whether the CAF acknowledges the presence of extremism in their organization, and how the CAF responds to this issue. Using a content analysis approach, news articles from The Globe and Mail and Departmental Plans from the Department of National Defence (DND) and the CAF are examined. The content of these sources is used to determine whether parallels can be drawn from news media reports on RWE in the military and reports generated by the CAF itself. The findings indicate that in the context of RWE, the CAF is generally portrayed negatively by the news media. More importantly, the findings suggest that the news media highlights the social and political context in Canada which might allow RWE beliefs to thrive. In contrast, reports from the CAF and DND prioritize presenting solutions to addressing RWE within the military by drawing focus on aspects of culture change. Ultimately, the CAF is not immune to the political and social influences that might divide Canadians. An environment that continues to provoke hate or violence motivated by hate places the CAF in a vulnerable position where it is not exempt from the influence of extremist beliefs.

description: Recent application cases of FAIR DOs in the context of Machine Learning show their usability to facilitate automated data processing and linking distributed data. However, the implementation and use of the FAIR DOs have highlighted the issues that need to be addressed in the future; i.e. the granularity of the data being represented by FAIR DOs (data sets vs data elements), the granularity of the attributes in the FAIR DO’s information record (general vs specific information), and the specifications for operations.
Greek Romans? An Analysis of Greek Funerary Inscriptions from Rome

description: This dissertation examines the Greek funerary inscriptions from Rome between the 1st and the beginning of the 5th century CE. The main goal was to examine together the material produced by the pagan, Christian and Jewish communities, in order to look at commonalities and differences in the epigraphic practice of these communities; this is a valuable approach, quite different from the traditional scholarly approach which focuses on one or two groups at once. This helps to show how these communities did not live separately, but side to side in the same city. The research also compared the Greek epigraphic practice from the city of Rome, whether it was informed by Latin practice or influenced by the practice of Greek-speaking areas (i.e., Asia Minor, Greece, etc.). Secondly, quantitative analysis has been used to look at language issues (in particular, syntax and formulas), the relationship between commemorator and dedicator, epithets, age at death and status of the deceased. This research has shown how complex this material is: the different communities influenced each other, and the Greek funerary inscriptions present the adaptation of some aspects and formulas from the contemporary Latin epigraphic practice, as well as different peculiarities which Greek-speaking immigrants probably introduced to the city of Rome from there areas of the Empire, in particular Asia Minor.

description: The recent measured γ*γ\rightarrow π^0 transition form factor in the space-like region by the Belle Collaboration together with the previous published results by CLEO, CELLO and BABAR collaborations are analyzed using the mathematical theory of Padé Approximants which provides a good and systematic description of the low energy region exemplified here with the extraction of the slope a_π and curvature b_π of the form factor in a model-independent way. The impact of them on the pion exchange contribution to the hadronic light-by-light scattering part of the anomalous magnetic moment a_μ is also discussed.
