description: Background: Admission to the intensive care unit (ICU) outside daytime hours has been shown to be variably associated with increased morbidity and mortality. We aimed to describe the characteristics and outcomes of patients admitted to the ICU afterhours (22:00–06:59 h) in a large Canadian health region. We further hypothesized that the association between afterhours admission and mortality would be modified by indicators of strained ICU capacity. Methods: This is a population-based cohort study of 12,265 adults admitted to nine ICUs in Alberta from June 2012 to December 2014. We used a path-analysis modeling strategy and mixed-effects multivariate regression analysis to evaluate direct and integrated associations (mediated through Acute Physiology and Chronic Health Evaluation (APACHE) II score) between afterhours admission (22:00–06:59 h) and ICU mortality. Further analysis examined the effects of strained ICU capacity and varied definitions of afterhours and weekend admissions. ICU occupancy ≥ 90% or clustering of admissions (≥ 0.15, defined as number of admissions 2 h before or after the index admission, divided by the number of ICU beds) were used as indicators of strained capacity. Results: Of 12,265 admissions, 34.7% (n = 4251) occurred afterhours. The proportion of afterhours admissions varied amongst ICUs (range 26.7–37.8%). Patients admitted afterhours were younger (median (IQR) 58 (44–70) vs 60 (47–70) years, p < 0.0001), more likely to have a medical diagnosis (75.9% vs 72.1%, p < 0.0001), and had higher APACHE II scores (20.9 (8.6) vs 19.9 (8.3), p < 0.0001). Crude ICU mortality was greater for those admitted afterhours (15.9% vs 14.1%, p = 0.007), but following multivariate adjustment there was no direct or integrated effect on ICU mortality (odds ratio (OR) 1.024; 95% confidence interval (CI) 0.923–1.135, p = 0.658). Furthermore, direct and integrated analysis showed no association of afterhours admission and hospital mortality (p = 0.90) or hospital length of stay (LOS) (p = 0.27), although ICU LOS was shorter (p = 0.049). Early-morning admission (00:00–06:59 h) with ICU occupancy ≥ 90% was associated with short-term (≤ 7 days) and all-cause ICU mortality. Conclusions: One-third of critically ill patients are admitted to the ICU afterhours. Afterhours ICU admission was not associated with greater mortality risk in most circumstances but was sensitive to strained ICU capacity.

Patient-reported questionnaires and quantitative sensory testing for central sensitization in endometriosis
Creators: name: Gentles, Avonae
Publisher: name: University of British Columbia
Year: 2025

description: Endometriosis is a chronic inflammatory condition affecting over 2 million Canadians. It is characterised by the growth of endometrial-like lesions outside the uterus, causing debilitating pain. Standard treatments include pain medication, hormonal therapy and surgery; yet 30-50% still experience pain. Endometriosis pain includes nociceptive, neuropathic, and nociplastic types. Nociplastic pain is characterized by central nervous system sensitization, which leads to hyperalgesia and allodynia, and provides an explanation for persistent and widespread pain. In Objective 1, I conducted a scoping review to identify tools for detecting nociplastic pain and central sensitization in endometriosis. This review listed potential clinical and research tools, including sensory tests and patient-reported questionnaires as useful proxies for central sensitization but highlighted gaps in research evaluating the efficacy of these tools. Objective 2 involved a retrospective analysis of the Endometriosis and Pelvic Pain Interdisciplinary Cohort registry (EPPIC) which looked at the association between the Pain Sensitivity Questionnaire (PSQ) with the Central Sensitization Inventory (CSI), central sensitivity syndromes, and patient-reported pain and quality of life. The PSQ was weakly correlated with the CSI (r=0.099, p<0.001) and showed weaker correlations with the central sensitivity syndromes (r=0.093, p<0.001) compared to the CSI (r=0.687, p<0.05). The PSQ was only associated with superficial dyspareunia (r=0.138, p<0.001) and back pain (r=0.091, p=0.014), whereas the CSI was significantly associated (i.e. p<0.05) with scores for dysmenorrhea, deep dyspareunia, superficial dyspareunia, back pain and chronic pelvic pain. In Objective 3, an interim analysis of an ongoing prospective study examined five pain questionnaires and six sensory tests across the hand, abdomen, and deltoid. Findings indicated a significant (i.e. p<0.05) strong relationship between the Self-Administered Leeds Assessment for Neuropathic and Nociceptive Signs and Symptoms (S-LANSS) with all questionnaires, except the PSQ: Douleur Neuropathique 4 Questionnaire (DN4; r=0.64), Michigan body map (MBM; r=0.58), and CSI (r=0.52). Additionally, pelvic mechanical hypersensitivity was linked to more widespread pain (r=0.75) and neuropathic-like symptoms (r=0.59). However, patient-reported symptoms were more strongly associated with the CSI and S-LANSS than sensory tests. Overall, endometriosis nociplastic pain is heterogeneous, and may require multiple assessment methods. Larger studies are needed to confirm these findings.

description: We investigate linear interference of a plane wave with different localised waves using coupled Fokas-Lenells equation(FLE) with four wave mixing (FWM) term. We obtain localised wave solution of the coupled FLE by linear superposition of two distinctly independent wave solutions namely plane wave and one soliton solution & plane wave and two soliton solution. We obtain several nonlinear profiles depending on the relative phase induced by soliton parameters. We analyse the linear interference profile under four different conditions on the spatial and temporal phase coefficients of interfering waves. We further investigate the interaction of two soliton solution and a plane wave. In this case we notice that asymptotically, two solitons profile may be similar or different from each other depending on the choices of soliton parameters in the two cases. The results obtained by us might be useful for applications in soliton control, a fiber amplifier, all optical switching, and optical computing. Further we believe that the present investigation would be useful to study the linear interference pattern of other localised waves of FLE.

A preliminary investigation into discursive models of interpreting as a means of enhancing construct validity in interpreter certification

description: Interpreter certification has been largely ignored by the literature in Interpreting Studies. What little research that does exist on the topic is understandably elementary, discussing concerns that are general in nature or describing the development of individual certification instruments. No research has as yet examined the psychometric properties of certification instruments, despite the urgings of legal precedent, the weight of professional opinion, and the requirements of professional standards. The present study has attempted to bridge this gap in two ways. First, to gain some sense of the current state of affairs in interpreter testing, a validation study of an existing certification test was conducted. Particular attention was paid to information about the test's constructs. Second, in a bid to improve construct validity, a new certification test was constructed and subsequently validated. Constructs in the new test were based on a discursive model of the interpreting process. Validation of the two tests revealed some interesting findings. Constructs in the existing test bore only a weak relationship to the interpreting profession. Also, the constructs did not prove to be useful in predicting relationships among the existing test scores. It was expected that three separate constructs would emerge from the data; instead, empirical evidence suggested that the data were unidimensional in nature. In contrast, constructs in the new test were strongly linked to the interpreting profession. They also proved to effectively predict relationships among the new test scores. It was expected that three separate constructs would emerge from the data, and empirical evidence suggested that this was, in fact, the case. The results of the present study indicate that there is room for improvement in the current state of interpreter testing, and that a test instrument based on discursive constructs is likely to demonstrate acceptable levels of validity. There is obviously a need for a great deal of future research on the psychometric aspects of interpreter certification, and it is strongly recommended that this research adopt a discursive approach.

Chatter detection and suppression using wavelet and fuzzy control approaches in end milling

description: In metal cutting processes, chatter has been recognized as one of the main factors that limit machining productivity and affect product quality. Two different categories of chatter were classified by researchers, i.e., regenerative chatter and non-regenerative chatter, and in this thesis the former is mainly studied. Over the past few decades, though various chatter detection and suppression methods have been developed, their industrial acceptance is still very limited. This research work presents a new system for on-line chatter detection and suppression. Its detection module implements a statistical index to identify chatters by performing wavelet transform and conducting statistical analysis of positive wavelet transform modulus maxima (WTMM). To suppress chatter, two versions of fuzzy control modules, i.e., plain fuzzy control and self-regulating fuzzy control have been implemented. Unlike the previous chatter suppression systems, the new suppression module features two-way adjustment, i.e., both increasing and decreasing the amount of adjustment. Along with the use of single or multi-output control variables to suppress chatter, productivity is preserved as much as possible. The proposed system is implemented on a SERVO 2000 milling machine. Extensive tests have been carried out. The experimental results show that the wavelet-based chatter detection index can not only detect the existence of chatters but also distinguish the severity levels. The new chatter suppression module works reasonably well in most tests. However, its performance is adversely affected in the presence of non-regenerative vibrations due to the lack of workpiece or clamping rigidity. Further improvements need to be carried out for industrial applications.

description: Background This study aimed to determine the number of people living with HIV receiving antiretroviral therapy (ART) between 2006 and 2013 in Germany by using the available numbers of antiretroviral drug prescriptions and treatment data from the ClinSurv HIV cohort (CSH). Methods The CSH is a multi-centre, open, long-term observational cohort study with an average number of 10.400 patients in the study period 2006–2013. ART has been documented on average for 86% of those CSH patients and medication history is well documented in the CSH. The antiretroviral prescription data (APD) are reported by billing centres for pharmacies covering >99% of nationwide pharmacy sales of all individuals with statutory health insurance (SHI) in Germany (~85%). Exactly one thiacytidine-containing medication (TCM) with either emtricitabine or lamivudine is present in all antiretroviral fixed-dose combinations (FDCs). Thus, each daily dose of TCM documented in the APD is presumed to be representative of one person per day receiving ART. The proportion of non-TCM regimen days in the CSH was used to determine the corresponding number of individuals in the APD. Results The proportion of CSH patients receiving TCMs increased continuously over time (from 85% to 93%; 2006–2013). In contrast, treatment interruptions declined remarkably (from 11% to 2%; 2006–2013). The total number of HIV-infected people with ART experience in Germany increased from 31,500 (95% CI 31,000-32,000) individuals to 54,000 (95% CI 53,000-55,500) over the observation period (including 16.3% without SHI and persons who had interrupted ART). An average increase of approximately 2,900 persons receiving ART was observed annually in Germany. Conclusions A substantial increase in the number of people receiving ART was observed from 2006 to 2013 in Germany. Currently, the majority (93%) of antiretroviral regimens in the CSH included TCMs with ongoing use of FDCs. Based on these results, the future number of people receiving ART could be estimated by exclusively using TCM prescriptions, assuming that treatment guidelines will not change with respect to TCM use in ART regimens.

description: Epidermal growth factor receptor (EGFR) signalling is activated by ligand-induced receptor dimerization. Notably, ligand binding also induces EGFR oligomerization, but the structures and functions of the oligomers are poorly understood. Here, we use fluorophore localization imaging with photobleaching to probe the structure of EGFR oligomers. We find that at physiological epidermal growth factor (EGF) concentrations, EGFR assembles into oligomers, as indicated by pairwise distances of receptor-bound fluorophore-conjugated EGF ligands. The pairwise ligand distances correspond well with the predictions of our structural model of the oligomers constructed from molecular dynamics simulations. The model suggests that oligomerization is mediated extracellularly by unoccupied ligand-binding sites and that oligomerization organizes kinase-active dimers in ways optimal for auto-phosphorylation in trans between neighbouring dimers. We argue that ligand-induced oligomerization is essential to the regulation of EGFR signalling.

description: Beginning in the early 1990's, the study of binary mixtures containing simple molecules under high pressure led to the discovery of a solid van der Waals compound: a weakly bound molecular solid whose cohesion is primarily due to van der Waals forces. The formation of this type of compound, such as He(N2)11 discovered in 1992 in the helium-nitrogen system by Vos et al. [Vos, 1992], is predicted in systems such as those containing nitrogen and methane. The nitrogen-methane binary system is studied at room temperature under high pressure in order to construct the pressure-concentration phase diagram up to 16 GPa. Over 20 mixtures of varying concentration have been studied within a diamond anvil cell through Raman spectroscopy and powder X-ray diffraction using synchrotron radiation. Within the phase diagram, phases exist that resemble the pure species at similar thermodynamic conditions, and additionally, two novel van der Waals compounds are observed.

description: Mobile computing, which combines the traditional data network and telecommunication networks, has been a very attractive and active paradigm in the field of network communications. The mobile computing environment not only provides communication between fixed and/or mobile devices, but also seeks to provide anytime, anywhere, personalized services and resource access to its mobile users. Mobile computing offers more flexibility to the mobile users, but it also raises new concerns to the field of Network Security , which has been gaining more and more attention for the last two decades. This thesis introduces a mobile computing system, the Personal Mobility Management System (PMMS), which has been implemented in the Multimedia and Mobile Agent Research Laboratory at University of Ottawa. The PMMS is a mobile computing application based on Agent technology and Blackboard Messaging Server. The thesis captures and analyzes the security weaknesses exposed in the system, and presents feasible approaches to overcome these concerns. The main purpose of the thesis work is to design and implement frameworks to ensure secure communications for the PMMS. Designs that will be discussed in details include user authentication, access control and secure communication framework for the system. Suggestions on future work are also presented at the end of the document.

description: Quantum effects in photosynthetic energy transport in nature, especially for the typical Fenna-Matthews-Olson (FMO) complexes, are extensively studied in quantum biology. Such energy transport processes can be investigated as open quantum systems that blend the quantum coherence and environmental noises, and have been experimentally simulated on a few quantum devices. However, the existing experiments always lack a solid quantum simulation for the FMO energy transport due to their constraints to map a variety of issues in actual FMO complexes that have rich biological meanings. Here we successfully map the full coupling profile of the seven-site FMO structure by comprehensive characterization and precise control of the evanescent coupling of the three-dimensional waveguide array. By applying a stochastic dynamical modulation on each waveguide, we introduce the base site energy and the dephasing term in colored noises to faithfully simulate the power spectral density of the FMO complexes. We show our photonic model well interprets the issues including the reorganization energy, vibrational assistance, exciton transfer and energy localization. We further experimentally demonstrate the existence of an optimal transport efficiency at certain dephasing strength, providing a window to closely investigate environment-assisted quantum transport.
Optical and Electrical Costimulation of Optogenetically-modified Neurons

description: This study investigated new approaches to controlling brain cells for bionic devices such as the cochlear implant. These devices typically use electrical signals to connect with and control brain cells. In this study, cells were genetically modified so that they could be controlled by light (a technique known as optogenetics). A combination of light and electrical stimulation was shown to interact to improve the response of brain cells compared to either light or electrical stimulation on its own. These results may improve future bionic devices which help people regain lost functions like movement, sight or hearing.
Experimental and theoretical study of a tubular flow reactor: Homogeneous liquid-phase reaction.

description: An experimental and theoretical study has been carried out for the evaluation of concentration and temperature profiles for non-isothermal liquid-phase reactions taking place in a vertical tubular reactor. Theoretically homogeneous, irreversible first- and second-orders reactions were investigated. Three different flow models were assumed: (1) plug flow, (2) laminar flow and (3) laminar flow accompanied by radial diffusion. In addition, two modes of reactor operations were considered: adiabatic and constant-wall-temperature (CWT) reactors with the hydrolysis of acetic anhydride being chosen as the reference reaction. The effects of flow model, reaction kinetics, reaction conditions and reactant concentrations on conversion and temperature rises were then investigated. Point concentration and temperature profiles were computed together with the corresponding flow average values. The results showed that under adiabatic reaction conditions, radial concentration and temperature profiles were greatly affected by both reaction conditions and flow model with the heat of reaction group, G4, having the most significant effect. It was also observed that large radial diffusion effects could significantly influence overall conversions. In the CWT reactor, curves were found to show a characteristic maximum which were again highly dependent on G4. It was found that in a CWT reactor, radial temperature variation could be expected even in plug flow and under laminar flow conditions, large G4 values increased conversions over those calculated for plug flow conditions. Inlet concentration effects were noted for both the adiabatic and the CWT reactors with reaction kinetics significantly affecting reactor performance. Experimental runs were carried out on a vertical reactor 250 cm. long and 1.865 cm. I.D. The inlet acetic anhydride concentration ranged from 0.291 to 1.470 mole/ℓ and the Reynolds number from 88 to 346. Temperatures varied from 25.57 to 38.91°C and the average velocity from 0.402 to 1.316 cm/sec. The reactor was operated under adiabatic and constant-wall-temperature conditions. Temperature rises were limited to 7°C in accordance with the assumptions formulated in theoretical models. Experimental results indicated that radial temperature profiles tended to be flat but showed some difference between the wall temperature and the centreline temperature compared to the value predicted by the plug flow model. The laminar flow model gave the closest agreement with experimental results. Six causes are possible for the observed difference between experimental and predicted results. However, the presence of acetic acid is considered to be the most influential.

description: Background: The principal aim of this study was to investigate whether a caregiver-inclusive assistive technology intervention improved older care recipients’ functional autonomy and decreased the perceived burden of their family caregivers compared to customary care. Methods: The study was a single-blind, mixed-methods, randomized controlled trial with baseline data collection and follow-ups at 6-, 22-, and 58-weeks after baseline evaluation, which was prospectively registered (ClinicalTrials.gov Identifier: NCT01640470. Registered 11/21/2011). Dyads comprising a care recipient and family caregiver were randomly assigned to either a caregiver-inclusive experimental group (N = 44) or a customary-care comparison group (N = 46). Eligible care recipients were aged ≥55 years and had one or more limitations with mobility or daily activities, and family caregivers provided at least four hours per week of assistance. Outcome measures were administered to both groups at baseline and at the three follow-up time points. The data collectors were blinded regarding participants’ intervention group. The primary outcome measures were the Functional Autonomy Measurement System to assess care recipients’ functional performance, and the Caregiver Assistive Technology Outcome Measure to assess caregivers’ burden. Qualitative interviews examined participants’ perceptions of the caregiver-inclusive and customary care interventions. Results: The experimental intervention addressed significantly more dyad-identified problematic activities, but caregiver involvement was evident in both groups and outcomes were not significantly different over time. In both groups, care recipients’ functional autonomy declined significantly (P < .01), and caregivers’ activity-specific and overall burden decreased significantly (P < .01). Conclusions: Given the unintended congruence between the caregiver-inclusive and customary care interventions, the overall findings lend support for the provision of assistive technology to reduce caregiver burden.

description: The radiative transition probabilities from the 3+ state at 2.18 Mev and the 0+ state at 3.56 Mev to the 1+ ground state are calculated using cluster model wave functions. In this model, the 3+ and the 1+ states are assumed to have an alpha-deuteron cluster structure and the 0+ state an alpha-deuteron cluster structure in which the deuteron cluster is excited to the lowest T = 1, S = 0 state. The results obtained were in reasonable agreement with the experimental values, thus confirming a good degree of accuracy of the cluster model wave functions for Li6.

description: We initiate the study of boundary Vertex Operator Algebras (VOAs) of topologically twisted 3d $\mathcal{N}=4$ rank-0 SCFTs. This is a recently introduced class of $\mathcal{N}=4$ SCFTs that by definition have zero-dimensional Higgs and Coulomb branches. We briefly explain why it is reasonable to obtain rational VOAs at the boundary of their topological twists. When a rank-0 SCFT is realized as the IR fixed point of a $\mathcal{N}=2$ Lagrangian theory, we propose a technique for the explicit construction of its topological twists and boundary VOAs based on deformations of the holomorphic-topological twist of the $\mathcal{N}=2$ microscopic description. We apply this technique to the $B$ twist of a newly discovered family of 3d $\mathcal{N}=4$ rank-0 SCFTs ${\mathcal T}_r$ and argue that they admit the simple affine VOAs $L_r(\mathfrak{osp}(1|2))$ at their boundary. In the simplest case, this leads to a novel level-rank duality between $L_1(\mathfrak{osp}(1|2))$ and the minimal model $M(2,5)$. As an aside, we present a TQFT obtained by twisting a 3d $\mathcal{N}=2$ QFT that admits the $M(3,4)$ minimal model as a boundary VOA and briefly comment on the classical freeness of VOAs at the boundary of 3d TQFTs.

Viability estimation for diffusion-based planning
Creators: name: Ioannidis, Nicholas
Publisher: name: University of British Columbia
Year: 2025

description: Diffusion models can be used as a motion planner by sampling from a distribution of possible futures. However, the samples may not satisfy hard constraints that exist only implicitly in the training data, e.g., avoiding falls or not colliding with a wall. We propose learned viability filters that efficiently predict the future success of any given plan, i.e., diffusion sample, and thereby enforcing an implicit future-success constraint that favours plans likely to succeed in the future. These filters identify samples from the output of a diffusion-based motion planner with respect to implicit constraints and take the general form of a learned Q-function. This allows for efficient online planning with diffusion models, including for situations where the diffusion model and viability filter have different access to environment observations. Multiple viability filters can also be composed together so that they are each taken into consideration. We demonstrate the approach on detailed footstep planning for challenging 3D human locomotion tasks, showing the effectiveness of viability filters in performing online planning and control for box-climbing, step-over walls, and obstacle avoidance. We further show that using viability filters is significantly faster than guidance-based diffusion prediction.

description: This study is a two-part study of day-hospital patients and NPHS data. Objectives. To determine the prevalence of potentially inappropriate medication use among the elderly; to examine the relationships between selected variables and this outcome; to construct a model to identify higher risk individuals. Predetermined criteria were used to identify potentially inappropriate medication use. 11.1% ($\pm$10.3) of male and 23.1% ($\pm$10.2) of female day-hospital patients were classified with this outcome. Univariate LR identified five variables; multivariate LR identified five variables. 7.3% ($\pm$1.6) of Canadian elderly men and 7.1% ($\pm$1.3) of Canadian elderly women, taking at least one medication, were classified with this outcome. Univariate LR identified 14 variables; multiple LR identified five variables. Reducing the occurrence of potentially inappropriate medication use will lead to reduced drug-related morbidity, lower health care costs, and increased quality-of-life.

description: Variable scene layouts and coexisting objects across scenes make indoor scene recognition still a challenging task. Leveraging object information within scenes to enhance the distinguishability of feature representations has emerged as a key approach in this domain. Currently, most object-assisted methods use a separate branch to process object information, combining object and scene features heuristically. However, few of them pay attention to interpretably handle the hidden discriminative knowledge within object information. In this paper, we propose to leverage discriminative object knowledge to enhance scene feature representations. Initially, we capture the object-scene discriminative relationships from a probabilistic perspective, which are transformed into an Inter-Object Discriminative Prototype (IODP). Given the abundant prior knowledge from IODP, we subsequently construct a Discriminative Graph Network (DGN), in which pixel-level scene features are defined as nodes and the discriminative relationships between node features are encoded as edges. DGN aims to incorporate inter-object discriminative knowledge into the image representation through graph convolution and mapping operations (GCN). With the proposed IODP and DGN, we obtain state-of-the-art results on several widely used scene datasets, demonstrating the effectiveness of the proposed approach.
Unmasked: Public relations' struggle for legitimacy in post- World War II West Germany

description: This thesis offers new insights into the conceptual distinction between public relations and propaganda, by examining public relations' 're-birth' in post-World War II West Germany. The findings suggest that public relations presented an identity that masked its true identity as self-advantaging communication that, in the same way as propaganda, seeks to reinforce or modify the attitudes and/or behaviour of an audience to advantage the communicator. In an era of digital disruption and 'fake news', as public relations again faces challenges of legitimacy, this research raises questions about truth, transparency and accountability for public relations, both as an academic discipline and a profession.

description: Convex functions of quantum states play a key role in quantum physics, with examples ranging from Bell inequalities to von Neumann entropy. However, in experimental scenarios, direct measurements of these functions are often impractical. We address this issue by introducing two methods for determining rigorous confidence bounds for convex functions based on informationally incomplete measurements. Our approach outperforms existing protocols by providing tighter bounds for a fixed confidence level and number of measurements. We evaluate the performance of our methods using both numerical and experimental data. Our findings demonstrate the efficacy of our approach, paving the way for improved quantum state certification in real-world applications.
