description: WebChecker is a plugin for Epsilon Validation Language (EVL), designed to validate both static and dynamic HTML pages utilizing frameworks like Bootstrap. By employing configurable EVL constraints, WebChecker enforces implicit rules governing HTML and CSS frameworks. The effectiveness of the plugin is demonstrated through its application on Bootstrap, the widely adopted HTML, CSS, and JavaScript framework. WebChecker comes with a set of EVL constraints to assess Bootstrap based web pages. To substantiate our claims, I present an illustrative example featuring two solutions that effectively enforce implicit rules.

description: In this paper, a Kinect-based distributed and real-time motion capture system is developed. A trigonometric method is applied to calculate the relative positions of Kinect v2 sensors with a calibration wand and register the sensors’ positions automatically. By combining results from multiple sensors with a nonlinear least square method, the accuracy of motion capture is optimized. Moreover, to exclude inaccurate results from sensors, a computational geometry is applied in the occlusion approach to discover occluded joint data. The synchronization approach is based on the NTP protocol, which synchronizes the time between the clocks of a server and of clients dynamically, leading to the proposed system being real time. Experiments to validate the proposed system are conducted from the perspective of calibration, occlusion, and accuracy. More specifically, the mean absolute error of the calibration results is 0.73 cm, the proposed occlusion method is tested on upper and lower limbs, and the synchronization component guarantees the clock synchronization and real-time performance for more than 99% of the measurement process. Furthermore, to demonstrate the practical performance of our system, a comparison with previously developed motion capture systems (the linear trilateration approach [52] and the geometric trilateration approach [51]) with the benchmark Opti Track system is performed for the tracked joints of the head, shoulder, elbow, and wrist, therein showing that the accuracy of our proposed system is 38.3% and 24.1% better than the aforementioned two trilateration systems. Quantitative analysis is also conducted on our proposed system with the commercial inertial motion capture system Delsys smart sensor system by comparing the measurements of lower limbs (i.e., hips, knees, and ankles), and the standard deviation of our proposed system’s measurement results is 4.92 cm.

description: [Context and Motivation]: Cyber-Physical Systems (CPS) have become relevant in a wide variety of different domains, integrating hardware and software, often operating in an emerging and uncertain environment where human actors actively or passively engage with the CPS. To ensure correct and safe operation, and self-adaptation, monitors are used for collecting and analyzing diverse runtime information. [Problem]: However, monitoring humans at runtime, collecting potentially sensitive information about their actions and behavior, comes with significant ramifications that can severely hamper the successful integration of human-machine collaboration. Requirements engineering (RE) activities must integrate diverse human values, including Privacy, Security, and Self-Direction during system design, to avoid involuntary data sharing or misuse. [Principal Ideas]: In this research preview, we focus on the importance of incorporating these aspects in the RE lifecycle of eliciting and creating runtime monitors. [Contribution]: We derived an initial conceptual framework, building on the value taxonomy introduced by Schwartz and human value integrated Software Engineering by Whittle, further leveraging the concept of value tactics. The goal is to tie functional and non-functional monitoring requirements to human values and establish traceability between values, requirements, and actors. Based on this, we lay out a research roadmap guiding our ongoing work in this area.

description: Smart grid is an emerging technology that aims to empower the current power grid with the integration of two-way communication and computer technology. This thesis deals with energy management in smart grid with focus on the smart home and the Intelligent Transportation System (ITS). The smart home contains a network that connects home elements like smart appliances, HVAC (heating, ventilation, and air conditioning), thermostat, smart meter, sensors, solar panels and energy storage. ITS integrates computer and communication technologies for advanced traffic management and communication among road infrastructure, vehicles and users. A web service describes a collection of operations that are accessible via the Internet. Web services can also provide security and interoperability. Due to the rising cost of energy, more and more residential consumers are interested in controlling temperature or appliances in order to reduce energy consumption. In this thesis, we propose an approach that uses Web services to remotely and efficiently interact with smart home devices in order to manage energy consumption, in a smart grid environment. Consequently, the user is able to adjust the temperature, control appliances or read energy consumption values quickly, remotely and securely. A smart home with a wireless network based on ZigBee and XMPP (eXtensible Messaging and Presence Protocol) is simulated. The advantage of XMPP is that it provides near real-time communication and security. There is a central computer that can communicate with all home elements. Business Process Execution Language (BPEL) is used to implement the Web service on a central computer. Furthermore, quality of service is offered. Therefore, different levels of security and an access control mechanism are provided. An algorithm is proposed that can sell stored energy back to the grid from smart home. Another algorithm is proposed that can facilitate demand response. Moreover, dynamic programming is used to minimize energy consumption. Also, a broadcasting algorithm is presented that can be used by an electric vehicle to find the most suitable charging station in ITS. Simulation and analytical study is undertaken to demonstrate the performance and advantage of the proposed approach and algorithms.

description: Large Language Model (LLM) inference uses an autoregressive manner to generate one token at a time, which exhibits notably lower operational intensity compared to earlier Machine Learning (ML) models such as encoder-only transformers and Convolutional Neural Networks. At the same time, LLMs possess large parameter sizes and use key-value caches to store context information. Modern LLMs support context windows with up to 1 million tokens to generate versatile text, audio, and video content. A large key-value cache unique to each prompt requires a large memory capacity, limiting the inference batch size. Both low operational intensity and limited batch size necessitate a high memory bandwidth. However, contemporary hardware systems for ML model deployment, such as GPUs and TPUs, are primarily optimized for compute throughput. This mismatch challenges the efficient deployment of advanced LLMs and makes users pay for expensive compute resources that are poorly utilized for the memory-bound LLM inference tasks.
 We propose CENT, a CXL-ENabled GPU-Free sysTem for LLM inference, which harnesses CXL memory expansion capabilities to accommodate substantial LLM sizes, and utilizes near-bank processing units to deliver high memory bandwidth, eliminating the need for expensive GPUs. CENT exploits a scalable CXL network to support peer-to-peer and collective communication primitives across CXL devices. We implement various parallelism strategies to distribute LLMs across these devices. Compared to GPU baselines with maximum supported batch sizes and similar average power, CENT achieves 2.3$\times$ higher throughput and consumes 2.9$\times$ less energy. CENT enhances the Total Cost of Ownership (TCO), generating 5.2$\times$ more tokens per dollar than GPUs.

description: This thesis investigates the perceptual and cognitive reality of Schenkerian theory through a survey of relevant empirical research. It reviews existing Schenkerian-specific empirical research, examines general tonal research applicable to Schenkerian analysis, and proposes the possibility of an optimal empirical research method by which to explore the theory. It evaluates data dealing with musical instruction’s effect on perception. From this review, reasonable evidence for the perceptual reality of Schenkerian-style structural levels is found to exist. This thesis asserts that the perception of Schenkerian analytical structures is largely an unconscious process.

description: The cyanotoxin cylindrospermopsin was discovered during a drinking water-related outbreak of human poisoning in 1979. Knowledge about the degradation of cylindrospermopsin in waterbodies is limited. So far, only few cylindrospermopsin-removing bacteria have been described. Manganese-oxidizing bacteria remove a variety of organic compounds. However, this has not been assessed for cyanotoxins yet. We investigated cylindrospermopsin removal by manganese-oxidizing bacteria, isolated from natural and technical systems. Cylindrospermopsin removal was evaluated under different conditions. We analysed the correlation between the amount of oxidized manganese and the cylindrospermopsin removal, as well as the removal of cylindrospermopsin by sterile biogenic oxides. Removal rates in the range of 0.4-37.0(my)L-1 day-1 were observed. When MnCO3 was in the media Pseudomonas sp. OF001 removed round about 100% of cylindrospermopsin in 3 days, Comamonadaceae bacterium A210 removed round about 100% within 14 days, and Ideonella sp. A288 and A226 removed 65% and 80% within 28 days, respectively. In the absence of Mn2+, strain A288 did not remove cylindrospermopsin, while the other strains removed 5-16%. The amount of manganese oxidized by the strains during the experiment did not correlate with the amount of cylindrospermopsin removed. However, the mere oxidation of Mn2+ was indispensable for cylindrospermopsin removal. Cylindrospermopsin removal ranging from 0 to 24% by sterile biogenic oxides was observed. Considering the efficient removal of cylindrospermopsin by the tested strains, manganese-oxidizing bacteria might play an important role in cylindrospermopsin removal in the environment. Besides, manganese-oxidizing bacteria could be promising candidates for biotechnological applications for cylindrospermopsin removal in water treatment plants. © 2019 Elsevier Ltd.

description: Macrophages can be polarized into M1 and M2 macrophages based on the composition of the milieu. Human macrophages have been poorly characterized. In this study, various macrophage subsets were generated by treating monocyte-derived macrophages (MDMs) with IFNγ (M1), IL-4 (M2a), LPS and IL-1β (M2b) or IL-10 (M2c) which were characterized with respect to their cell surface marker profile and functional profile in the context of cytokine production, susceptibility to HIV infection and apoptosis. Each polarization state demonstrated a unique cell surface marker profile and cytokine profile. In addition M1 macrophages were shown to produce IFNγ post TLR stimulation. Moreover, M1 macrophages were highly sensitive to apoptosis following Smac mimetic treatment. Furthermore, M2a and M2c macrophages were resistant to apoptosis, induced by PI3K blockage and IAPs degradation respectively, and at the same time supported productive HIV infection unlike the other macrophage subsets. These findings might lead to better understanding of HIV reservoir formation and be used to develop therapies to eradicate it.
The future role of community radio as registered training organisations

description: This paper will look into the future role of community radio as Registered Training Organisations (RTOs) by giving an overview of the current training environment and the associated financial difficulties. Training could become a potential source of income for community radio, as training is perhaps the most fundamental activity undertaken by community radio. Community radio has become a stepping-stone for future commercial broadcasters to train and gain on-air experience. This function of the sector has been formalised with community radio organisations gaining RTO status. As RTOs, however, there is a major role community radio stations play that could be cultivated.

description: Each implant loading protocol had its merits and demerits. After loading, immediate loading implants and surrounding bones may respond differently to the applied masticatory force. Two 3D finite element models were designed representing each loading condition (immediate and delayed loading). The implant components included implant fixture carrying a stud overdenture attachment. All materials were set as isotropic except for bones where anisotropic behavior was selected. A frictional surface-to-surface contact was assigned to the bone-implant interface of the immediate loading finite element model while a bonded contact was used for delayed loading model. Another frictional contact was also used between the plastic clip and stud abutment for both groups. The models were mesh and refined in the finite element meshing module. Both models were constrained at the inferior border of the bone with (0-Dgree) of freedom in all axes. Three combined dynamic loads (time-dependent) were applied on the outer surface of the metallic housing of the attachment. Von mises stress and strain were evaluated for implants and attachments and maximum and minimum principles stresses were assessed for both compact and cancellous bones. The results of the immediate loading model showed higher von misses stress values at the implant and the stud abutment components than the delayed loading group, respectively. Similarly, both maximum and minimum principle stress of the immediate loading bones were higher than that of the delayed loading bones.

The Role of Ldb1 in ErbB2/Neu-induced Mammary Tumorigenesis
Creators: name: Ahmed, Sarra
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2015

description: The ste-20 like kinase (SLK) is a serine/threonine kinase activated downstream of Neu signaling and functions to mediate efficient migration and invasion of breast cancer cells. Previously, the LIM domain binding protein 1 (Ldb1) has been identified as a negative regulator of SLK kinase activity in MEF3T3 fibroblasts. Ldb1 is a transcriptional cofactor required for normal mouse embryonic development. In the current study we sought to assess the effect of mammary gland-specific Ldb1 deletion on SLK activity and metastasis in a Neu-overexpressing breast cancer model, the MMTV-NIC mouse model. Our results show that Ldb1 deletion does not affect SLK activity in Neu- induced tumors as demonstrated by in-vitro kinase assays. Also, Ldb1 deletion in the mammary epithelium of the MMTV-NIC model does not affect Neu-mediated tumor growth or overall survival. Due to the low incidence of spontaneous metastasis in the model, we performed tail-vein lung colonization assays and found that Ldb1 deletion significantly inhibits the lung colonization capability of primary tumor cells. Taken together, our findings highlight the important implications of understanding Ldb1- mediated transcriptional activity in Neu-overexpressing breast tumors as it could offer therapeutic opportunity to limit the spread of metastatic Neu-induced breast cancers.

description: LoRa is currently one of the most widely used low-power wide-area network (LPWAN) technologies. The physical layer leverages a chirp spread spectrum modulation to achieve long-range communication with low power consumption. Synchronization at long distances is a challenging task as the spread signal can lie multiple orders of magnitude below the thermal noise floor. Multiple research works have proposed synchronization algorithms for LoRa under different hardware impairments. However, the impact of sampling frequency offset (SFO) has mostly either been ignored or tracked only during the data phase, but it often harms synchronization. In this work, we extend existing synchronization algorithms for LoRa to estimate and compensate SFO already in the preamble and show that this early compensation has a critical impact on the estimation of other impairments such as carrier frequency offset and sampling time offset. Therefore it is critical to recover long-range signals.

description: Physician well-being has become an important area of interest given that reduced well-being can have a negative effect on patient outcomes. However, research has predominantly focused on impairment thus studies addressing physicians' positive functioning are limited. The purpose of this two-phase, mixed methods study was to investigate the well-being and self-regulation capacity of physicians using a positive psychology lens. In Phase 1, 132 physicians (n = 40 physicians; n = 92 resident physicians) completed online questionnaires to assess their levels of psychological and affective well-being and self-regulation capacity. Selected based on Phase 1 data, 12 physicians then took part in an in-depth individual interview in Phase 2 to discuss their experiences of psychological well-being and self-regulation. Results of Phase 1 showed that physicians and resident physicians had moderate and high levels of self-regulation capacity, respectively. While both groups reported high levels of psychological well-being, they had average levels of positive and negative affect. MANOVAs confirmed the hypothesis that high self-regulating physicians and resident physicians would have higher levels of psychological well-being and positive affect compared to those with lower levels. However, those with higher self-regulation capacity did not have lower negative affect, nor did physicians have significantly higher levels of psychological and affective well-being than resident physicians. Regression analyses confirmed the hypothesis that a significant amount of variance in levels of psychological well-being would be explained by self-regulation capacity. There was a particularly strong relationship between self-regulation capacity and the dimensions of purpose in life and environmental mastery, which suggests that physicians who effectively self-manage may be better able to preserve a sense of purpose and an adequate work-life balance in their daily life. A qualitative content analysis of the Phase 2 qualitative data revealed that physicians had both high and low functioning experiences of psychological well-being across the dimensions of self-acceptance, positive relations with others, environmental mastery, and autonomy. They, however, reported high functioning for the dimensions of personal growth and purpose in life. Their experiences also varied based on their professional and personal life contexts, with work-life balance emerging as a prevalent theme. Physicians' self-regulation experiences involved individualized preparation, performance, and evaluation processes that were perceived to influence their well-being. Results of a composite analysis suggest that the development of effective self-regulation skills could be one way to help physicians achieve satisfactory levels of well-being.

description: Data from multiple experiments suggest that the current interaction models used in Monte Carlo simulations do not correctly reproduce the hadronic interactions in air showers produced by ultra-high-energy cosmic rays (UHECR). We have created a large library of UHECR simulations where the interactions at the highest energies are slightly modified in various ways - but always within the constraints of the accelerator data, without any abrupt changes with energy and without assuming any specific mechanism or dramatically new physics at the ultra-high energies. Recent results of the Pierre Auger Observatory indicate a need for a change in the prediction of the models for both the muon content at ground and the depth of the maximum of longitudinal development of the shower. In our parameter space, we find combinations of modifications that are in agreement with this analysis, however a consistent description of UHECR showers remains elusive. Our library however provides a realistic representation of the freedom in the modeling of the hadronic interactions and offers an opportunity to quantify uncertainties of various predictions. This can be particularly valuable for the design of future observatories where hadronic models are often used as input for the prediction of the performance. We demonstrate this powerful capability on several selected examples.

description: This paper makes the case for studying intermediary organisations as a window on the shifting governance of water and energy services in Europe today. It explores the notion of intermediaries and intermediation in a wide range of literatures and demonstrates how the governance concept can provide focus to the term, indicating how intermediaries can influence the pursuit of collective goals under shifting governance structures and processes. Against this conceptual backdrop the paper sets out the key governance challenges emerging from the ongoing transformation of socio-technical systems (addressing water and energy services) in terms of changing relations between the state and the utility, between service provider and user, between infrastructure and urban systems and between infrastructure and the environment. It subsequently provides empirical illustration of the emergence of intermediaries in the water sector across Europe, the relational nature of their work, the interests they pursue and the impacts they are having.

description: One of the focal points of contemporary theological controversy has been the notion that ordained priests act in persona Christi. Both defenders and critics of this concept are relying on unverified historical assumptions, which can only diminish the credibility of their arguments. The objective of the present dissertation is to provide a credible answer to the question of the existence of historical antecedents to in persona Christi theology. The body of literature studied spans the period from 200 –750 CE. Liturgical sources pertaining to the ordained ministry are analysed first. These include most of the ancient church orders (the Apostolic Tradition, the Didascalia, the Canons of Hippolytus, the Apostolic Constitutions, the Testamentum Domini, and the Statuta Ecclesiae Antiqua), as well as ordination rites from Egypt, Rome, Gaul, Spain, Byzantium, and Georgia. With a few exceptions, these liturgical sources do not contain instances of sacerdotal representation-of-Christ. The study proceeds with an examination of theological sources, which include nineteen church writers: Tertullian, Origen, Cyprian of Carthage, Cyril of Jerusalem, Gregory of Nazianzus, Pacian, Ambrose of Milan, Ambrosiaster, John Chrysostom, Theodore of Mopsuestia, Augustine, Dionysius the Areopagite, Narses of Edessa, Severus of Antioch, Gregory the Great, Isidore of Seville, Maximus the Confessor, Bede the Venerable, and John Damascene. Ten out of these nineteen writers attribute some form of representativity to the ordained priest. Of those ten, most consistently portray the ordained priest as representing Christ, while for the others the object of representation is occasionally Christ, but more frequently "God" or "the Deity." A few authors—Augustine in particular—fall outside these categories. Notwithstanding the variations and exceptions, it can safely be concluded that (1) there are enough genuine instances of sacerdotal representation-of-Christ in the theological sources of the patristic period, and (2) there is enough logical consistency among these instances, that it can be considered a strong, recognizable current of thought. The findings of our study lead to the conclusion that the emergence of the idea of sacerdotal representation-of-Christ was not an isolated phenomenon and did indeed constitute an element of the church's common tradition, long before the scholastic period.

description: Positive psychology has significantly advanced our understanding of well-being, yet there remains a need to better understand the how, what, and why of both positive and negative well-being. This study combined positive psychology and job loss perspectives to investigate the subjective experience of well-being following job loss. Using a qualitative-focused case study methodology, this three article dissertation explored the experiences of 20 workers who were displaced from the Ottawa, Canada technology sector from 2000-2006. The first article explored the experience of well-being from a bottom-up, naturalistic point of view and compared these inductive notions with existing a priori theories. Findings support integrated conceptualizations of hedonia and eudaimonia, while also potentially identifying new notions of well-being. Identified themes include (a) life evaluation, (b) transitory experiencing, (c) growth and grounding, (d) environmental mastery/stability, (e) mental ill-being/ill-health, and (f) motivational mindsets/conditions. This study showed well-being to be a rich, pluralistic construct. It included the non-dualistic notions of both subjectivity and objectivity, as well as encompassing notions related to the what and how of well-being. The second and third articles present inductively derived themes which helped to explain the relationship between job loss and well-being (i.e., the how and why). Three externally focused themes were reported in the second article: (a) systemic factors (e.g., broader business environment), (b) interpersonal factors (e.g., social support), and (c) chance (e.g., luck and serendipity). The third article identified two internally focused major themes: (a) differential coping responses and processes and (b) protective and sensitizing processes. Coping specifically consisted of problem-focused coping, meaning-making, attitudes and expectancies, behavioural processes, and emotional processes. Protective and sensitizing processes included identity and self-esteem, the impact of past adversity, and personal resources and characteristics. Implications for theory, research, and practice for both positive psychology and job loss are discussed.

description: Understanding the quantum control landscape (QCL) is important for designing effective quantum control strategies. In this study, we analyze the QCL for a single two-level quantum system (qubit) using various control strategies. We employ Principal Component Analysis (PCA), to visualize and analyze the QCL for higher dimensional control parameters. Our results indicate that dimensionality reduction techniques such as PCA, can play an important role in understanding the complex nature of quantum control in higher dimensions. Evaluations of traditional control techniques and machine learning algorithms reveal that Genetic Algorithms (GA) outperform Stochastic Gradient Descent (SGD), while Q-learning (QL) shows great promise compared to Deep Q-Networks (DQN) and Proximal Policy Optimization (PPO). Additionally, our experiments highlight the importance of reward function design in DQN and PPO demonstrating that using immediate reward results in improved performance rather than delayed rewards for systems with short time steps. A study of solution space complexity was conducted by using Cluster Density Index (CDI) as a key metric for analyzing the density of optimal solutions in the landscape. The CDI reflects cluster quality and helps determine whether a given algorithm generates regions of high fidelity or not. Our results provide insights into effective quantum control strategies, emphasizing the significance of parameter selection and algorithm optimization.
Taking Root: Media, Community, and Belonging in Ottawa

description: This thesis employs a post-anarchist influenced lens and develops a collective capacity framework in order to explore how the media consumption and production practices of the Chinese Canadian, Latin American, and Somali Canadian communities in Ottawa, Canada, can strengthen these communities’ ability to facilitate the process by which immigrants become community members and form a sense of belonging in Ottawa. The thesis explores both how ethno-cultural media can help newcomers to form a sense of belonging and become part of a local ethno-cultural community, as well as how such media can help members of minority ethno-cultural communities become part of the broader local community and to form a sense of belonging in Ottawa, and Canada more broadly. Throughout, the thesis identifies and explores the differences that emerge between the three communities in order to gain better insight into the potential benefits of ethno-cultural media. In order to explore and to answer these questions, the thesis employs quantitative and qualitative methods. It relies on analysis of secondary literature, raw data from the OMMI 2012 Survey, raw content coding of local Chinese and Spanish language media carried out as part of the Ottawa Multicultural Media Initiative, and primary research consisting of content coding of a Somali Canadian television program. The main contribution of this thesis lies in offering a new lens through which to assess the integrative potential of ethno-cultural media. Approaching the question from a bottom-up, relationship-centred perspective has yielded different findings than those generally reported in Canadian ethno-cultural media research. Although there were significant differences in terms of media use and media production between the three communities, the findings revealed that all three used ethno-cultural media in ways that had the potential to help them in the process of settling down and taking root in a new city, and of helping them to form a sense of belonging.

description: Balancing part-time work while studying full-time at university has become increasingly common in Canada. While there is research into the effects of students’ term-time work on their persistence and grades, there is little Canadian research that examines other aspects of working students’ lives. This report addresses this gap by presenting findings from two online surveys of undergraduate students at the University of British Columbia about their term-time work in 2018 and 2019. Since this is the first stage of a mixed-methodology study, impressions from our initial qualitative data collection (in process) have been included as a starting point for further conversation between qualitative and quantitative results. The findings of this study construct a profile of ‘the working student’, including their motivations for working, the intensity of that work, and self-perceived working conditions. Since work-integrated learning (WIL) aims to develop students’ professional skills through meaningful employment related to studies, we also compare WIL with other forms of student work.

description: Negation is a fundamental aspect of human communication, yet it remains a challenge for Language Models (LMs) in Information Retrieval (IR). Despite the heavy reliance of modern neural IR systems on LMs, little attention has been given to their handling of negation. In this study, we reproduce and extend the findings of NevIR, a benchmark study that revealed most IR models perform at or below the level of random ranking when dealing with negation. We replicate NevIR's original experiments and evaluate newly developed state-of-the-art IR models. Our findings show that a recently emerging category-listwise Large Language Model (LLM) re-rankers-outperforms other models but still underperforms human performance. Additionally, we leverage ExcluIR, a benchmark dataset designed for exclusionary queries with extensive negation, to assess the generalisability of negation understanding. Our findings suggest that fine-tuning on one dataset does not reliably improve performance on the other, indicating notable differences in their data distributions. Furthermore, we observe that only cross-encoders and listwise LLM re-rankers achieve reasonable performance across both negation tasks.

description: End-to-end visibility in global supply chains has become a critical factor in achieving operationalefficiency, transparency, and resilience. The complexity of modern supply chains, characterized by multiplestakeholders and the movement of goods across borders, presents significant challenges in tracking, monitoring,and ensuring the authenticity of products. This paper explores the integration of blockchain technology andartificial intelligence (AI) to enhance end-to-end visibility in global supply chains. Blockchain provides animmutable, decentralized ledger that enables transparent tracking of goods, while AI adds predictive analytics andreal-time decision-making capabilities to optimize operations. By combining these technologies, organizationscan achieve greater traceability, reduce the risk of fraud, enhance inventory management, and improve overallsupply chain performance. The research highlights real-world case studies and examines the challenges andopportunities associated with implementing blockchain and AI in supply chains. This approach represents atransformative shift towards more secure, efficient, and data-driven supply chain management.

description: We explore purely metric theories of gravity with second-order equations of motion and a single additional, purely gravitational, propagating, scalar degree of freedom. We identify a subclass of these theories in which this scalar causes a phenomenon similar to black-hole scalarization, which we call curvaturization: around small enough Kerr black holes, the scalar induces a tachyonic instability. This triggers a sudden growth of Ricci curvature and results in a new branch of vacuum black-hole solutions. We study the properties of these black holes both in the static as well as the spinning case.

description: In the teleost brain, radial glial cells (RGCs) are the main macroglia and are stem- like progenitors that express key steroidogenic enzymes, including the estrogen- synthesizing enzyme, aromatase B (cyp19a1b). As a result, RGCs are integral to neurogenesis and neurosteroidogenesis in the brain, however little is known about the permissive factors and signaling mechanisms that control these functions. The aim of this thesis is to investigate if the secretogranin-derived neuropeptide secretoneurin (SN) can exert regulatory control over goldfish (Carassius auratus) RGCs. Immunohistochemistry revealed a close neuroanatomical relationship between RGCs and soma of SNa- immunoreactive magnocellular and parvocellular neurons in the preoptic nucleus in both goldfish and zebrafish (Danio rerio) models. Both intracerebroventricular injections of SNa into the third brain ventricle and SNa exposures of cultured goldfish RGCs in vitro show that SNa can reduce cyp19a1b expression, thus implicating SNa in the control of neuroestrogen production. RNA-sequencing was used to characterize the in vitro transcriptomic responses elicited by 1000 nM SNa in RGCs. These data revealed that gene networks related to central nervous system function (neurogenesis, glial cell development, synaptic plasticity) and immune function (immune system activation, leukocyte function, macrophage response) were increased by SNa. A dose-response study using quantitative proteomics indicates a low 10 nM dose of SNa increased expression of proteins involved in cell growth, proliferation, and migration whereas higher doses down- regulated proteins involved in these processes, indicating SNa has dose-dependent regulatory effects. Together, through these altered gene and protein networks, this thesis proposes SNa exerts trophic and immunogenic effects in RGCs. These datasets identified a total of 12,180 and 1,363 unique transcripts and proteins, respectively, and demonstrated that RGCs express a diverse receptor and signaling molecule profile. Therefore, RGCs can respond to and synthesize an array of hormones, peptides, cytokines, and growth factors, revealing a multiplicity of new functions critical to neuronal-glial interactions.
