description: In Intelligent Transport Systems (ITS), the unavailable Road Side Unit (RSU) becomes an increasing serious safety-related problem because of its important role in ITS. However, there is no existing method to solve this problem effectively and stably nowadays. To solve the unavailable RSU problem, a novel 2-tier integrated communication system is proposed in this thesis to address the issue of unavailable RSU in ITS. Compared to some other solutions proposed in the previous research works, which mostly focus on improving the system performance by adjusting parameters of vehicular ad-hoc network among vehicles, the proposed 2-tier communication network, called ITS-LEO Integrated System (ILIS), is composed of conventional ITS system and Low Earth Orbit (LEO) mobile satellite system (MSS), where the LEO MSS is utilized as the complementary network when the RSU is unavailable. Since the LEO MSS primary message will get affected when overflowing messages from ITS to LEO MSS, we prioritize LEO MSS primary message over the overflowed message to minimize the effect, which is based on that the emergency message (EMsg) is given higher priority over routine message (RMsg) to get access to the channel in ITS. To optimize the utility of network resource, two different overflowing mechanisms are proposed in ILIS to improve system efficiency under different traffic density. Furthermore, we propose a bandwidth reservation protection mechanism for ILIS to increase the ITS network performance. A real-time simulation program in C++ is developed to evaluate the performance of ILIS in terms of Packet Loss Rate (PLR) and Delay, and simulation results show that adding LEO MSS as a complementary network to ITS is an effective way to solve the problem of an unavailable RSU.

description: Il monitoraggio della biodiversità è essenziale per la biologia della conservazione e la crescente disponibilità di dati di citizen science su piattaforme online potrebbe facilitare notevolmente lo studio di processi ecologici legati a piante ed animali. Infatti, grazie a queste piattaforme, i ricercatori possono stimare la ricchezza e la distribuzione di specie protette o invasive, anche su vasta scala (da locale a globale). Tuttavia, le attuali piattaforme sono ancora lontane dall'essere uno strumento efficace nello studio dell'ecologia animale e quindi non sono ancora in grado di fornire dati ‘grezzi’ così robusti da supportare processi decisionali, fondamentali per la protezione e la conservazione delle risorse naturali. Infatti, spesso i dati archiviati sulle piattaforme citizen science sono stati raccolti in maniera opportunistica (non utilizzando protocolli standardizzati, né campionamenti randomizzati) rendendo difficile una valutazione oggettiva della loro qualità per la ricerca scientifica. Un esempio di bias legato alle piattaforme citizen science consiste nell’archiviazione dei soli dati di presenza (escludendo completamente quelli di assenza) che porta ad interpretazioni limitate sulla distribuzione delle specie. Inoltre, i dati di queste piattaforme sono tipicamente sbilanciati in favore dei centri abitati o delle zone frequentate dagli osservatori più attivi. Inoltre i dati posso anche essere distribuiti in maniera sbilanciata verso i paesi più sviluppati. Infine molte osservazioni sono tassonomicamente sbilanciate in favore di specie di grandi dimensioni e comuni, carismatiche, dai colori vivaci e facili da rilevare. Per questo, nel nostro studio forniamo linee guida per superare la maggior parte dei limiti sopracitati e per rendere le piattaforme online più efficaci nel colmare le lacune di specie e siti sottorappresentati. In particolare, affrontiamo come migliorare ed armonizzare le prestazioni sia in termini di rappresentatività di specie e taxa che di robustezza statistica per fornire stime affidabili di presenza e abbondanza delle specie.

Navigating Climate Change: Rethinking the Role of Buildings
Creators: name: Cole, Raymond J.
Publisher: name: Multidisciplinary Digital Publishing Institute
Year: 2020

description: This paper focuses on the design of buildings as part of society’s response to the climate crisis in the aftermath of the COVID-19 pandemic. It draws on a broad literature to address two interrelated goals—first, to align regenerative development and design with the necessary bottom-up adaptation strategies and human agency, and second, to identify new, broader possible roles of buildings and responsibilities of design professionals. This required a comparison of current green building and emerging regenerative approaches and identifying the relevant characteristics of top-down and bottom-up mechanisms. The paper accepts that adaptation to climate change will, to a large extent, depend on people’s day-to-day actions in the places they live, and argues that the built environment will have to be infused with the capability to enable inhabitants’ greater agency. Viewing buildings as playing a connective role in the existing urban fabric seriously challenges the primacy of the individual building as the focus of environmental strategies. The roles of building design professionals will likely expand to include mediating between top-down imposed government controls and increasing bottom-up neighborhood-scale social activism.

description: Backpropagation (BP) has been a successful optimization technique for deep learning models. However, its limitations, such as backward- and update-locking, and its biological implausibility, hinder the concurrent updating of layers and do not mimic the local learning processes observed in the human brain. To address these issues, recent research has suggested using local error signals to asynchronously train network blocks. However, this approach often involves extensive trial-and-error iterations to determine the best configuration for local training. This includes decisions on how to decouple network blocks and which auxiliary networks to use for each block.
In our work, we introduce a novel BP-free approach: a block-wise BP-free (BWBPF) neural network that leverages local error signals to optimize distinct sub-neural networks separately, where the global loss is only responsible for updating the output layer. The local error signals used in the BP-free model can be computed in parallel, enabling a potential speed-up in the weight update process through parallel implementation. Our experimental results consistently show that this approach can identify transferable decoupled architectures for VGG and ResNet variations, outperforming models trained with end-to-end backpropagation and other state-of-the-art block-wise learning techniques on datasets such as CIFAR-10 and Tiny-ImageNet. The code is released at https://github.com/Belis0811/BWBPF.

description: The gas-phase ion chemistry of hydroxyl- and amino-substituted polycyclic aromatic hydrocarbons (PAHs) and their protonated counterparts were studied using mass spectrometry. Ions were generated using an electron ionization (EI) source and the unimolecular chemistry of metastable ions was studied by performing mass-analysed ion kinetic energy spectrometry (MIKES) experiments with a magnetic sector tandem mass spectrometer. Collision-induced dissociation (CID) experiments were used in conjunction with MIKES experiments to determine ion structure. The ten molecules studied were: 1-naphthol, 2-naphthol, 1-naphthylamine, 2-naphthylamine, 1-aminoanthracene, 2-aminoanthracene, 1-phenanthrol, 9-phenanthrol, 1-hydroxypyrene and 1-aminopyrene. Since it is believed that larger PAHs, on the order of more than 50 carbon atoms, populate the interstellar medium, the goal of this study was to attempt to extrapolate the results from smaller systems to larger ones. The trends found include: hydroxy-substituted PAH radical cations lose carbon monoxide spontaneously and amino-substituted PAH radical cations lose HCN. Mechanisms for both processes are proposed, and it appears from the present results that this process should extrapolate to larger PAHs. Another trend found was that all the remaining fragment ions were always a closed ring. Protonated amino-substituted PAHs were generated by electrospray ionization using a quadruple time-of-flight mass spectrometer. By protonating 1-naphthol and 2-naphthol using methane in the high-pressure EI source, it was found that they lost exclusively H2O. As for 2-naphthylamine, 1-aminoanthracene and 2-aminoanthracene, it was found that 2-naphthylamine lost NH3 and a hydrogen atom, NH3being the dominant channel. However, as the ion size 3 increases, the hydrogen-loss channel became the dominant channel. This means that larger PAHs will likely lose exclusively a hydrogen atom to reform the parent radical cation.

Randomized Controlled Trial

description: Background: With usual supplementation practices, most children are Vitamin D Deficient (VDD) following Congenital Heart Disease (CHD) surgery and alternative regimens need consideration. Methods/Results: i) A systematic review identified 88 pediatric trials of high dose vitamin D. Studies evaluating the Institute of Medicine (IOM) Tolerable Upper Intake Level (UL) did not rapidly normalize levels, while loading therapy (≥ 40000 IU) did so within 3 days. Hypercalcemia occurred more often with doses above 400000 IU. ii) A double blind RCT was designed to determine whether pre-operative administration of the IOM UL can prevent post-operative VDD. Results after the first 30 participants completed study procedures demonstrated it was possible to recruit (1.8 patients per month) and complete study procedures (i.e. blood collection). Unfortunately few participants (45%) received more than 30 doses of study drug. Conclusion: Prevention of post-operative VDD in the majority of CHD patients will require alternatives to the IOM recommendations.

description: Extensive consumption of carbon resources has led to decreasing reserves of fossil fuels and growing concern about global warming. This dilemma has promoted a shift in the economy to develop new long-term, environmentally friendly, and sustainable sources for fuels and chemicals to replace fossil fuel-based sources. Renewable biomass is an ideal alternative, as it is abundant, and relatively cheap. Among current biofuel resources, 5-hydroxymethylfurfural (5-HMF) is a versatile intermediate between biomass-based carbohydrate chemistry and fossil fuel-based industrial organic chemistry, which can be used to synthesize a broad range of chemicals that are currently derived from fossil fuel-based resources. Carbohydrates became the preferred feedstock for high yield production of 5-HMF, and the most convenient route for the synthesis of 5-HMF is the acid-catalyzed dehydration of hexose. Within this context, a variety of processes were developed for the synthesis of 5-HMF from dehydration of fructose involving various solvents, including water, organic solvents, and biphasic systems. Likewise, a range of catalysts were employed, such as homogeneous acid catalysts and metal chlorides, which showed high catalytic activity. Heterogeneous catalysts have also been receiving attention due to their advantages such as easy recovery and recyclability. In the current research, microwave-assisted synthesis of 5-HMF by dehydration of fructose over various acidic porous catalysts, such as periodic mesoporous organosilica (PMO), carbon materials, and metal organic frameworks (MOFs), was investigated. The results showed that the obtained 5-HMF yields were satisfactory, and more importantly highlighted some of the properties of porous heterogeneous catalysts that may improve the production of 5-HMF.

description: Concentrator photovoltaics (CPV) is one of the most promising renewable technologies owing to its high efficiency, scalability, low operating expense, and small environmental impact. However, there is much research and advancements to be made before CPV is established as a cost competitive energy technology. To this end, Morgan Solar has developed the Sun Simba, an innovative light weight and low cost CPV module. Under the “Advancing Photonics for Economical Concentration Systems” (APECS) project, outdoor CPV test and measurement systems were designed and constructed at the University of Ottawa and at Little Rock, CA. The performance and reliability of development stage Sun Simba modules installed at the University of Ottawa is assessed. The Little Rock test system was constructed for purposes of future comparison and assessment. To properly assess the performance, instrumentation and data acquisition systems to measure meterological parameters and the associated electrical performance are described and the long-term performance of Sun Simba modules installed at the University of Ottawa is summarized. A finite element model of a cell-on-carrier assembly was constructed to explore the parameter space of the carrier and suggest improvements in carrier design. The effect of carrier geometry, material choices, and convective boundary conditions and their influence on the cell efficiency is determined. The modelling results connected to the measured data is used to estimate the heat sinking capability of the second generation Sun Simba modules.

description: Background-Pulmonary artery hypertension (PAH) is characterized by progressive vascular changes causing increased pulmonary resistance and eventual right heart failure (HF). It has been suggested that altered myocardial substrate utilization may be associated with right HF, however these changes have not yet been well characterized. The aim of this study was to evaluate in vivo right ventricular (RV) function and RV glucose and fatty acid metabolism in an experimental model of PAH using non-invasive positron emission tomography (PET) imaging and to investigate the effect of a novel endothelin receptor antagonist, Macitentan, on the development of PAH and RV energetics. Methods and Results-Severe PAH was induced in a total of 11 male Sprague-Dawley rats using a single injection of Sugen5416 followed by chronic hypoxia. The rats were then randomized to treatment or no treatment with Macitentan (30 mg/kg daily) Five and eight weeks post injection, substrate utilization was serially assessed with 2-[18F]fluoro-2-deoxyglucose (FDG) and 4-[18F]fluoro-6-thia-heptadecanoate (FTHA) PET scans for glucose and fatty acid metabolism respectively, and reported as a standardized uptake value (SUV). This data was correlated with in vivo functional measurements with echocardiography and multi gated acquisition scans. The Sugen-hypoxia (SuHx) model resulted in an increase in RV FDG uptake over 8 weeks (SUV control: 1.56 ± 0.38, week 5 SuHx: 4.06 ± 1.90, week 8 SuHx: 4.00 ± 1.60, p<0.005 between control and week 5 SuHx). RV FTHA data showed a trend towards increased uptake with onset of PAH at week 5 SuHx (SUV control: 1.50 ± 0.40, week 5 SuHx: 3.06 ± 1.10, p>0.05). Macitentan significantly decreased RV FDG uptake (SUV week 8 SuHx: 4.00 ± 1.60, week 8 SuHx +ERA: 2.54 ± 0.90, p<0.05). This was associated with improved RV ejection fraction (PAH week 8 untreated: 53.15 ± 9.9% vs PAH week 8 treated: 73.22 ± 4.8%, p<0.01) and improved pulmonary artery pressures measured by pulmonary artery acceleration time (PAH week 8 untreated: 17.32 ± 2.30 ms vs. PAH week 8 treated: 24.38 ± 3.90 ms, p<0.001). There was a strong correlation between increased pulmonary artery pressures and increased RV FDG uptake (r=0.87, p=0.001) as well as a significant inverse relationship between improved RV ejection fraction and decreased RV FDG uptake (r=-0.72, p=0.01). Conclusion-PAH is associated with metabolic changes in the RV, characterized by increased glucose uptake and a trend towards increased RV fatty acid uptake with onset of PAH. Macitentan attenuated RV FDG uptake and significantly increased RV function as well as hemodynamics compared to untreated group.

This report is a systematic evaluation that was conducted using 10,000 synthetic datasets designed to mimic real-world complexities. These datasets varied in the number of states, the number of rows (representing independent sequences), the length of each sequence, and the presence of missing values. The number of sequence spells per dataset ranged from 300 to 2,000 to assess the impact of sample size on edge weight estimation. Sequence lengths were set between 15 and 100 states per row to account for both short and long temporal patterns. Furthermore, a random number of missing values (between 0 and 20 per sequence) was introduced to evaluate the robustness of estimations under incomplete data conditions, which reflects the variability often found in real-world educational datasets with varying session sizes. The objective of this report is to analyze the results of this evaluation assessed with four primary categories of metrics: weight deviation, correlation, similarity, and dissimilarity measures (Saqr, Tikka, and López-Pernas 2024). The analysis was performed using the compare function of the tna package with minmax scaling to ensure both networks are compared on the same scale.

description: Circadian rhythms are approximately 24-hour oscillations of nearly every biological process in the body. The circadian system coordinates these rhythms of physiology and behavior with environmental cycles such as the light-dark cycle. Shift workers, who experience irregular exposure to the light-dark cycle, have chronically disrupted circadian rhythms and increased risk of developing cardiovascular disease, but the mechanisms are unknown. Our studies investigated the effects of light-induced circadian disruption on atherosclerosis in ApolipoproteinE-deficient (ApoE-/-) mice. We found that male ApoE-/- mice housed in constant light for 12 weeks, which results in severe disruption of circadian rhythms or arrhythmicity, developed significantly more atherosclerosis compared to mice in control light-dark conditions, and this increase was attributed to increased atherogenic VLDL/LDL cholesterol fractions. Next, we mimicked circadian disruption experienced by shift workers by housing ApoE-/- mice in chronic jet lag conditions where the light-dark cycle was advanced by 6-hours every week for 12 weeks. In female ApoE-/- mice, we found that that chronic jet lag caused a 70% increase in atherosclerosis and a 23% increase in cholesterol, which was in VLDL/LDL fractions. Together, these data show that light-induced circadian disruption increases atherosclerosis, in part via exacerbated dyslipidemia.

description: Rural communities depend on the forest sector to fulfill their subsistence needs and maintain economic well-being. The forest sector in Kentucky plays an important role in the state’s rural economic development through provision of market and non-market goods and services along with employment. However, there is lack of understanding of how Kentucky communities’ dependence on forest sector is correlated with the communities’ economic well-being. This research examines the economic contribution of the forest sector and uses common indicators of forest sector dependence and economic well-being to explore the relationship between forest sector dependence and economic well-being at three regional levels across Kentucky. Different forms of regression and correlation analyses were applied. Results show that different forest sub-sectors in different regions have mixed relationships with indicators of economic well-being. These results could be applicable in designing incentive programs to support sustainable and thriving forest sector in the state.

description: Over the past recent years, β-aminocarbonyls have been of great interest to medicinal chemists. As a practical method to obtain these moieties, alkene aminocarbonylation, accounting for the formation of a C-N and a C-C bond, has been the subject of limited research efforts (very specific intramolecular metal-catalyzed variants have been reported). Direct aminocarbonylation of alkenes constitutes a challenging and an important potential innovation in the synthesis of β-aminocarbonyls such as β-amino acids. The research efforts described in the present thesis have been primarily directed towards the development of concerted pathways for the amination of alkenes using hydrazine derivatives as bifunctional reagents. Building on our previous report on the reactivity of hydrazides, progress on the aminocarbonylation of alkenes along with the synthetic scope of this reactivity are herein provided. Therefore, the first part of the present thesis (Chapter 2) focuses primarily on the development of thermolytic conditions for the intramolecular aminocarbonylation of alkenes using amino-isocyanates. Alongside, development of imino-isocyanates have provided complementary synthetic tools for aminocarbonylation. The second part (Chapter 3) describes the work accomplished towards intermolecular aminocarbonylation of alkenes and the synthesis of complex azomethine imine products (Chapter 3). Finally, the last part of the discussion (Chapter 4) will be on the development of new hydrazide reagents for the intramolecular Cope-type hydroamination of alkenes. In doing so, description of the synthetic utility of amino-isocyanates as amphoteric reagents for cascade reactions and heterocyclic synthesis will be provided.

Towards Context-Aware Personalized Recommendations in an Ambient Intelligence Environment
Creators: name: Alhamid, Mohammed F.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2015
Subjects: Personalized search
Context-aware recommendation
Retrieval model
Information filtering

description: Due to the rapid increase of social network resources and services, Internet users are now overwhelmed by the vast quantity of social media available. By utilizing the user’s context while consuming diverse multimedia contents, we can identify different personal preferences and settings. However, there is still a need to reinforce the recommendation process in a systematic way, with context-adaptive information. This thesis proposes a recommendation model, called HPEM, that establishes a bridge between the multimedia resources, user collaborative preferences, and the detected contextual information, including physiological parameters. The collection of contextual information and the delivery of the resulted recommendation is made possible by adapting the user’s environment using Ambient Intelligent (AmI) interfaces. Additionally, this thesis presents the potential of including a user’s biological signal and leveraging it within an adapted collaborative filtering algorithm in the recommendation process. First, the different versions of the proposed HPEM model utilize existing online social networks by incorporating social tags and rating information in ways that personalize the search for content in a particular detected context. By leveraging the social tagging, our proposed model computes the hidden preferences of users in certain contexts from other similar contexts, as well as the hidden assignment of contexts for items from other similar items. Second, we demonstrate the use of an optimization function to maximize the Mean Average Prevision (MAP) measure of the resulted recommendations. We demonstrate the feasibility of HPEM with two prototype applications that use contextual information for recommendations. Offline and online experiments have been conducted to measure the accuracy of delivering personalized recommendations, based on the user’s context; two real-world and one collected semi-synthetic datasets were used. Our evaluation results show a potential improvement to the quality of the recommendation when compared to state-of-the-art recommendation algorithms that consider contextual information. We also compare the proposed method to other algorithms, where user’s context is not used to personalize the recommendation results. Additionally, the results obtained demonstrate certain improvements on cold start situations, where relatively little information is known about a user or an item.

description: The biodiesel-diesel-ethanol blend represents an important alternative fuel for diesel engines; however, changes in the fuel composition and the introduction of new alternative fuel often results in corrosion and degradation of the automobile fuel system parts. In this present study, the corrosion behavior of carbon steel in B20D70E10 (biodiesel 20%, diesel 70% and ethanol 10%) fuel blend was studied by static immersion at room temperature and 60 C. The effect of B20D70E10 fuel blend on corrosion rate, morphology of corrosion products, and chemical structure of carbon steel were studied. In addition, the change of fuel properties, namely, total acid number, density, viscosity, calorific value, flash point, and color changes were also investigated. Moreover, fuel compositional changes, such as water content and oxidation product level in the fuel blends were examined. The results showed that the degradation of fuel properties and corrosion rate of carbon steel in B20D70E10 are lower than neat biodiesel (B100), whereas slightly higher than petro-diesel (B0).
Implementation of a Computerized Decision Support System for Warfarin Dosing in Hemodialysis Patients: A Study of Effectiveness and Safety

description: Statement of the problem: The risk-benefit profile of warfarin anticoagulation in hemodialysis (HD) patients differs compared to the non-HD population. Computerized decision support systems (CDSS) to assist with anticoagulation management are safe and effective in the non-HD population but had not previously been studied in HD outpatients. Methods of investigation: A before – after study compared anticoagulation control during pre-existing, nephrologist-led anticoagulation management to that following implementation of a pharmacist-led, CDSS-assisted strategy, in HD patients on warfarin at The Ottawa Hospital. Results: Forty-two patients were included. Following implementation of the CDSS-assisted strategy, median time-in-range increased by 3.7% (IQR, -9.5% - 20.6%; p = 0.247). Median frequency of INR tests per day decreased: -0.040 (IQR, -0.074 to –0.0008; P = 0.0001). Adverse events were similar. Conclusion: A CDSS-assisted strategy for anticoagulation management in HD patients is effective, safe and may lead to cost savings related to less frequent INR testing.
Dissolved Organic Matter Kinetically Controls Mercury Bioavailability to Bacteria in Lake Water from the Canadian Arctic

description: The repercussions of rapid climate-change are felt worldwide, but particularly in Arctic and Subarctic regions. Evidence of recent changes in water chemistry is being recorded in Arctic aquatic ecosystems, bringing further attention to contaminant dynamics in these environments. I assessed the role of dissolved organic matter (DOM) in controlling the bioavailability of mercury (Hg), a top priority among Arctic contaminants, to aquatic food webs using a bacterial bioreporter under oxic conditions. Experiments were performed under pseudo- and non-equilibrium conditions, in both defined media and water samples from tundra lakes with a large gradient in DOM. Inorganic HgII was considerably more bioavailable under non-equilibrium conditions than when DOM was absent or when HgII and DOM had reached pseudoequilibrium (24h). Under these enhanced uptake conditions, HgII bioavailability followed a bell shaped curve as DOM concentrations increased, both for defined media and field samples, suggesting that complexation kinetics and binding thresholds on DOM determine HgII bioavailability to methylating bacteria, and likely MeHg concentrations, the bioaccumulative neurotoxic form of Hg. Experiments also suggest that DOM may alter cell wall properties to facilitate the first steps toward HgII internalization via facilitated or active transport, and yet without altering overall cell wall permeability. While further research on ternary (HgII-cell-DOM) interaction is warranted, I propose a molecular shuttle model for DOM in facilitating bacterial HgII uptake, and the existence of a short-lived yet critical time window (<24h) during which DOM facilitates the entry of newly deposited HgII from the atmosphere into aquatic food webs.

description: Task-oriented semantic communication has emerged as a fundamental approach for enhancing performance in various communication scenarios. While recent advances in Generative Artificial Intelligence (GenAI), such as Large Language Models (LLMs), have been applied to semantic communication designs, the potential of Large Multimodal Models (LMMs) remains largely unexplored. In this paper, we investigate an LMM-based vehicle AI assistant using a Large Language and Vision Assistant (LLaVA) and propose a task-oriented semantic communication framework to facilitate efficient interaction between users and cloud servers. To reduce computational demands and shorten response time, we optimize LLaVA's image slicing to selectively focus on areas of utmost interest to users. Additionally, we assess the importance of image patches by combining objective and subjective user attention, adjusting energy usage for transmitting semantic information. This strategy optimizes resource utilization, ensuring precise transmission of critical information. We construct a Visual Question Answering (VQA) dataset for traffic scenarios to evaluate effectiveness. Experimental results show that our semantic communication framework significantly increases accuracy in answering questions under the same channel conditions, performing particularly well in environments with poor Signal-to-Noise Ratios (SNR). Accuracy can be improved by 13.4% at an SNR of 12dB and 33.1% at 10dB, respectively.
