description: Brief hypomania lasting less than 4 days may impair functioning and help to detect bipolarity. This study analyzed brief hypomania that occurred in patients with bipolar disorder who were diagnosed according to the DSM-IV criteria. Daily self-reported mood ratings were obtained from 393 patients (247 bipolar I and 146 bipolar II) for 6 months (75,284 days of data, mean 191.6 days). Episodes of hypomania were calculated using a 4, 3, 2, and single day length criterion. Brief hypomania occurred frequently. With a decrease in the minimum criterion from 4 days to 2 days, there were almost twice as many patients with an episode of hypomania (102 vs. 190), and more than twice as many episodes (305 vs. 863). Single days of hypomania were experienced by 271 (69%) of the sample. With a 2-day episode length, 33% of all hypomania remained outside of an episode. There was no significant difference in the percent of hypomanic days outside of an episode between patients with bipolar I and II disorders. There were no significant differences in the demographic characteristics of patients who met the 4-day minimum as compared with those who only experienced episodes of hypomania using a shortened length criterion. Decreasing the minimum length criterion for an episode of hypomania will cause a large increase in the number of patients who experience an episode and in the aggregate number of episodes, but will not distinguish subgroups within a sample who meet the DSM-IV criteria for bipolar disorder. Frequency may be an important dimensional aspect of brief hypomania. Clinicians should regularly probe for brief hypomania.

description: C'est suite a notre lecture de Bergson et de Sartre, que le soupcon qui est a l'origine de ce travail s'imposa a notre esprit. En lisant, en effet, ces deux monuiments de la philosophie contemporaine, nous fumes frappe et surpris par des nombreuses similitudes qui emaillent leurs oeuvres en general, et l'Essai sur les donnees immediates de la conscience et L'etre et le neant en particulier. L'affinite qui existe entre ces deux ouvrages est telle que, par moment, n'eut ete la difference de style--poetique chez Bergson et baroque chez Sartre--on croirait lire un meme auteur. Cette etrange proximite constatee entre les deux penseurs nous etonna. D'une part, parce que ces philosophes n'appartiennent pas au meme courant; d'autre part, parce que Sartre s'est toujours montre hostile a l'endroit de Bergson. Ainsi avons-nous voulu savoir si malgre tout, Bergson n'a pas exerce une influence decisive sur Sartre. Autrement dit, nous cherchions a savoir si, en depit de son dedain pour Bergson, l'auteur de L'etre et le neant n'a pas abondamment puise dans la philosophie bergsonienne; s'il ne prolonge pas, quelque part, la pensee de Bergson; et, finalement, s'il n'existe pas une certaine "communaute d'orientation" entre les deux philosophes. Pour repondre adequatement a ces questions, il nous a fallu les comparer, c'est-a-dire mettre en exergue a la fois ce qui les eloigne et ce qui les rapproche. Comme nous ne pouvions appliquer cette comparaison en considerant tous les concepts qu'ils ont etudies, nous nous sommes donc limite a la notion du temps (dans l'Essai et dans L'etre et le neant). Bref, ce travail est une confrontation historique et critique--autour du concept de temps--a l'issue duquel nous espeions tirer au clair la nature du rapport qui existe entre Bergson et Sartre. Nous sommes arrive a la conclusion suivante: La temporalite sartrienne est certes differente de la duree bergsonienne. Cependant, suite aux nombreux recoupements que nous avons deceles, nous affirmons que Sartre a suffisamment subi l'influence bergsonienne. Son attitude negative a l'egard de Bergson s'expliquerait par des raisons doctrinales et historiques.

description: The purpose of this qualitative action research study was to explore how an academic coaching curriculum could help students develop an anxiety reducing workflow to improve students’ willpower, self-regulation, and self-control with the ultimate goal of helping students achieve their goals. This study aimed to further understand the work of academic coaches in higher education. There were four research questions that guided this study: (1) How does teaching an anxiety-reducing workflow influence a student’s willpower, mental energy, anxiety, and time management? (2) What elements of an academic coaching curriculum influence behavior change among students? (3) How can an academic coaching curriculum influence student goal achievement? (4) How do students with ADHD describe their experience with an academic coaching curriculum? This study analyzed five college students’ experiences with an academic coaching curriculum. Study findings indicated that the academic coaching curriculum positively influenced coached students’ willpower, mental energy, anxiety, and time management. Findings from this study also indicated that students improved their study strategies, self-advocacy behaviors, sleep routines, and perceived their breaks as more restorative. Further findings found that students perceived that academic coaching helped them achieve their goals, and the students with ADHD perceived that academic coaching helped them better understand their ADHD symptoms. I explore the process and features of academic coaching and make recommendations about how the academic coaching curriculum used in this study could be integrated into an overall student success strategy.
Bolstering the hegemony of the financial panopticon over emerging markets: A neo-Gramscian reading of the role of ideas, material capabilities and institutions.

description: he impact on the global landscape of the (re-)entry into the international financial system of a large number of middle-income transition and developing countries---the so-called "emerging markets"---has taken many observers by surprise. The Mexican and Asian crises were but two examples of the materialization and worldwide reverberations of inherent contradictions within the emerging market phenomenon; i.e. contradictions between powerful, disembedded and unaccountable financial forces and political forces that are still organized on a territorial basis within relatively weak and vulnerable economics. This thesis deploys a neo-Gramscian constructivist analysis to examine efforts by elements within a nascent transnational historical bloc of financial forces to overcome the risk of a Polanyian double movement to protect emerging market societies. More precisely, as this thesis reveals. there is mounting evidence of an hegemonic project seeking to bolster the emerging synthesis of material capabilities, ideas and institutions appropriate for an eventual hegemonic dominance of financial capital over emerging markets. Eschewing a problem-solving approach to financial matters, this thesis critically examines the roles (i) of material capabilities wielded through collectively allocated financial capital flows, (ii) of the intersubjective meanings given to financial globalization and the subsequent blueprint for commonsensical policymaking, and (iii) of central banks, credit-raters and the IMF in institutionalizing the coercive and consensual power relations at the heart of the emerging hegemonic bloc.

description: Background: Childhood overweight and obesity is a major public health concern. Community-based interventions have the potential to reach caregivers and children. However, the overall health impact of these programs is rarely comprehensively assessed. This study evaluated a physical activity and healthy eating family program (Healthy Together; HT) using the RE-AIM framework. Methods: Ten sites implemented the 5-week program. Thirty-nine staff members and 277 program participants (126 caregivers [M age  = 35.6] and 151 children [M age  = 13]) participated in the evaluation. Each RE-AIM dimension was assessed independently using a mixed-methods approach. Sources of data included archival records, interviews and surveys. Effectiveness outcome variables were assessed at pre- and post-intervention and 6-month follow-up. Results: Reach: HT participants were almost entirely recruited from existing programs within sites. Effectiveness: Caregivers’ nutrition related efficacy beliefs increased following HT (ps < .03). Participation in HT was not associated with significant changes in physical activity or nutrition behaviour or perceived social support (ps > .05). Knowledge surrounding healthy diets and physical activity increased in children and caregivers (ps < .05). Adoption: Thirty-five percent of sites approached to implement HT expressed interest. The 10 sites selected recruited existing staff members to implement HT. Implementation: Program objectives were met 72.8% of the time and 71 adaptations were made. HT was finance- and time-dependent. Maintenance: Two sites fully implemented HT in the follow-up year and 5 sites incorporated aspects of HT into other programs. Conclusions: Working alongside organizations that develop community programs to conduct comprehensive, arms-length evaluations can systematically highlight areas of success and challenges. Overall HT represents a feasible community-based intervention; however further support is required in order to ensure the program is effective at positively targeting the desired outcomes. As a result of this evaluation, modifications are currently being implemented to HT.

description: U.S. Higher education has hosted students from around the world. The U.S. has a top host country, but its position has been threatened because of the pollical climate and the growth of other host countries. This dissertation conducted three different studies of international student experience and success to explore the effective supports, which should be a key to continue to be attractive for international students. The first study examines the relationship between first-year international students’ interactions with people on campus and changes in psychological well-being. Results highlight the importance of positive peer interactions over other forms of interaction. The second study investigates the association between roommates’ or floormates’ nationalities and academic success of international and domestic students. The findings indicate that domestic students with international roommates tend to have worse academic outcomes, while international students’ grades, retention, and graduation remain consistent regardless of their roommates’ or floormates’ nationality. The third study challenges the stereotype of homogeneity among Asian international students and finds that their experiences can vary significantly overall and based on their backgrounds. This finding suggests that a one-size-fits-all approach to student preparation may not be inadequate, and more appropriate support should be developed. This dissertation suggests that U.S. higher education should provide opportunities for international students to connect with both domestic and international peers, and train faculty, staff, and students to acquire better intercultural communication skills.

description: Absorption chillers can use waste heat, solar heat, or excess heat by cogeneration facilities to supply chilled water. Therefore, absorption chillers are important components for poly-generation, which can improve plant utilization and efficiency of the overall energy supply system. Currently, 27 new small and medium-scale (30–160 kW cooling capacity) absorption chillers with high efficiency in full- and part-load as well as low specific size and weight are the focus of two research projects sponsored by German Federal Ministries. The chillers are located in 20 different sites, four of them in Jordan and the rest in Germany. The main objective of these projects is to enhance trigeneration and solar cooling system efficiency. The Jordan projects and more than 70% of the German installations use dry cooling towers. Combined heat and power (CHP) plants or district heating grids provide the driving heat for regeneration at the German installations. Solar thermal collectors drive one German and all Jordan installations. Within the projects, the chillers are provided with an intelligent control algorithm that allows achieving several objectives at the same time. One of the objectives, of course, is to match the desired chilled water temperature as well as the cooling capacity. Another objective is, for instance, to fit the hot water outlet temperature. This is commonly essential in cogeneration to avoid emergency shutdowns of the CHP engine. The field operation shows that the deviation of said temperatures from the set point is usually less than ±0.5 K in operation. In those operational hours in which the temperatures of the heat source or heat sink do not allow to reach all objectives, a set of hierarchical aims can be established within the algorithm so that the chiller can be controlled to match its prioritized objectives. Furthermore, the designed absorption chiller performs dynamically and autonomously in a very large range of temperatures and flow rates. These can vary from 20% up to 150% of nominal conditions. This flexibility can be used to achieve up to 80% savings of electrical power consumption using speed-controlled pumps in part load conditions. In contrast to the common opinion that small and medium-scale absorption chillers are not competitive as compared to compression chillers, this paper shows applications in which absorption chillers are advantageous because of synergies with and multiple benefits within the rest of the energy supply system.

description: Super-elevation on leveed rivers increases breach risk and causes waterlogging on floodplains. Sediment diversion channels can be constructed to serve as engineered levee breaks, allowing the release of floodwater and sediment from super-elevated channels. Diverted sediment and water can be put to beneficial use (e.g. construction and irrigation). To better evaluate the utility of sediment diversion channels for this purpose, we have closely studied the middle Kosi River in Bihar, India. We have created and calibrated series of numerical models using Delft3D that simulate flow and morphology on the Kosi with acceptable accuracy. Using parameters and boundary conditions from these models, we created a schematic model to test various diversion scenarios. The primary variables tested included offtake angle and threshold elevation. In our schematic model diversion channels set at a 45-degree angle to the main channel diverted up to three times as much flow and sediment compared to channels set at 25 and 90-degree angles. Captured portions of the upstream sediment load ranged from 2.5 percent to 17 percent. The total mass of sediment diverted by the year-round, 45-degree (YR45) scenario was 146,000 m3, which equates to a depth of 27 m spread over a football field.
description: We found that for Kosi sand with D50 of 0.34mm, channels must be carefully sized to maintain velocities near 1 m/s to prevent clogging and reduce maintenance requirements. When channels are appropriately sized, those set to lower threshold elevations and open year-round remove greater amounts of sediment. When channels are over-sized, the smaller channel will remove more sediment regardless of threshold elevation. Channels that diverted the greatest amount of flow and sediment had the greatest effect on the main channel, reducing downstream sediment transport capacity by as much as 36% and causing downstream accumulation. This accumulation may be responsible for raising water levels compared to the no-diversion scenario by the end of one year. Our findings indicate that while sediment diversion channels do have the potential to remove sediment from super-elevated riverbeds, the main channel effects must be minimized through careful design and investigation.

description: (1.1.1) Propopellane, I, is the ultimate propellane in terms of its small size and the inversion of the tetrahedral geometry about its bridgehead carbons. As such I is reactive towards radicals and carbenes. We have studied the kinetics and mechanisms of reaction of various carbon and heteroatom centered free radicals with I by nanosecond flash photolysis and product studies techniques.(DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI) The addition of diphenylcarbene (DPC) and phenylchlorocarbene (PCC) to I have also been investigated. Addition of DPC proceeds via a 1,4-biradical intermediate, II, whereas with PCC it appears that the final product, III, is formed directly upon reaction. The implications of the apparent concerted addition of the singlet carbene to I are discussed.(DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI) The role of I as a quencher of electronic excited states is also reported.

description: Galaxies with stellar masses near M* contain the majority of stellar mass in the universe, and are therefore of special interest in the study of galaxy evolution. The Milky Way (MW) and Andromeda (M31) have present day stellar masses near M*, at 5x10^10 Msol (MW-mass) and 10^11 Msol (M31-mass). We study the typical progenitors of these galaxies using ZFOURGE, a deep medium-band near-IR imaging survey, which is sensitive to the progenitors of these galaxies out to z~3. We use abundance-matching techniques to identify the main progenitors of these galaxies at higher redshifts. We measure the evolution in the stellar mass, rest-frame colors, morphologies, far-IR luminosities, and star-formation rates combining our deep multiwavelength imaging with near-IR HST imaging from CANDELS, and far-IR imaging from GOODS-H and CANDELS-H. The typical MW-mass and M31-mass progenitors passed through the same evolution stages, evolving from blue, star-forming disk galaxies at the earliest stages, to redder dust-obscured IR-luminous galaxies in intermediate stages, and to red, more quiescent galaxies at their latest stages. The progenitors of the MW-mass galaxies reached each evolutionary stage at later times (lower redshifts) and with stellar masses that are a factor of 2-3 lower than the progenitors of the M31-mass galaxies. The process driving this evolution, including the suppression of star-formation in present-day M* galaxies requires an evolving stellar-mass/halo-mass ratio and/or evolving halo-mass threshold for quiescent galaxies. The effective size and star-formation rates imply that the baryonic cold-gas fractions drop as galaxies evolve from high redshift to z~0 and are strongly anticorrelated with an increase in the S'ersic index. Therefore, the growth of galaxy bulges in M* galaxies corresponds to a rapid decline in the galaxy gas fractions and/or a decrease in the star-formation efficiency.
Counselling by health visitors In the treatment of postnatal depression

Postnatal depression

description: A randomised controlled trial of counselling by health visitors was conducted in health centres in Edinburgh and Livingston. Standardised measures of psychiatric morbidity were used to identify sixty women who were suffering from depression at about thirteen weeks postnatal. Fifty-five women gave their informed consent to participation in the trial, and were allocated using random numbers to the treatment group or a control group. Seventeen health visitors were given a brief training in methods of non-directive counselling, and were asked to pay eight consecutive weekly visits to women in the treatment group. Fifty women completed the trial. After a mean time interval of thirteen weeks, the women were re-interviewed, using the same measures of depression. The interviewer did not know to which group the mother had been assigned. The percentages of women who had recovered in the counselled and control groups were 69.2% and 37.5% respectively. The difference, 31. 7%, had a 95% confidence interval of 5% to 58%. The Chi squared statistic was 5.06, with an associated P value of 0.03. Although confidence in the robustness of these findings must be tempered by the small numbers in the trial, the superior rate of recovery of women in the treatment group is encouraging. Implications for the training of health visitors, in particular for the development of listening skills are discussed.

description: The focal point of this dissertation is the examination of innovation's impact on crowdfunding performance. To achieve this, we devise a text analytic method utilizing deep learning techniques to extract innovation-centric information from texts. We then conduct an empirical investigation to scrutinize the correlation between crowdfunding campaign performance and product innovation, as claimed by fundraisers. Moreover, we propose a comprehensive framework for quantifying product innovativeness, which entails comparing the claimed innovation with past innovation claims. We also analyze the impact of the new product development (NPD) stage on the relationship between product innovativeness and crowdfunding performance.
Accelerated simulation of ATM switching fabrics.

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1998
Subjects: subject: Mathematics.

description: Asynchronous transfer mode (ATM) is accepted as the solution to the broadband integrated services network known as B-ISDN. The information transmitted through an ATM network is divided into fixed sized packets, called cells. These cells traverse an ATM switching fabric, wherein they are electronically switched a number of times in order to arrive at the correct destination. For design purposes, it is important to know the cell loss ratio (CLR) for the buffers in an ATM switching fabric. We model the ATM switch, as an intree acyclical network of queues receiving N independent heterogenous Markov modulated input streams of cells. Due to the complexity of the model, simulations must be used to find the CLR for a hot spot buffer in the switching fabric. Crude Monte-Carlo simulations are not very efficient, since most services require a very small CLR, e.g. 10$\sp{-9}.$ Importance sampling techniques must be used. To make cell losses less rare, we increase (exponentially twist) the arrival rate of cells directed toward the hot spot buffer. We use the twisted probabilities with a splitting importance sampling technique to obtain an efficient estimate of the CLR for this buffer.
Relative preference for the therapeutic approaches of G. A. Kelly and A. Ellis as a function of locus of control and of situational powerlessness.

description: This study examined relative preference for the cognitively oriented therapeutic approaches of Kelly and Ellis. Levels of locus of control and four treatment conditions depicting types of powerlessness situations served as independent variables. Participants were 215 upper division male college preparatory students from a Chicago Catholic high school. Internals, moderates and externals were randomly assigned to one of four treatment conditions and exposed to standardized written descriptions of the two therapeutic approaches. Following a comprehension test on the descriptions, an audio-taped mini-lesson on imaginative skills and muted-role taking was presented. After a practice trial, each treatment condition received a taped presentation depicting one of four types of powerlessness: in the face of personally significant others, bureaucratic-institutional others, personal fate or chance. Participants' responses to a research questionnaire were submitted to factor analyses to provide guidelines for subsequent scale construction. Three scales served as dependent measures: an alternatives-irrationalities scale, a preference scale and an experimenter-teacher scale. Analyses of variance performed on each of the scales yielded no statistically significant differences as a function of locus of control or of treatment conditions, nor were statistically significant interactions observed. Further statistical analysis revealed a significant preference for Kelly's approach both by all levels of locus of control as well as by all four treatment conditions. These findings were discussed and limitations on their interpretations were presented. Suggestions for future research were offered.

description: With the evolution of electronic commerce (eCommerce) on the web and the rise of interests in intelligence of software agents, automated negotiation is becoming an increasingly popular method for an eCommerce system to be efficient; however, negotiation, which takes place in transaction, is complicated, time-consuming and costly for participants to reach an agreement. This thesis presents a model of an intelligent negotiation agent based on fuzzy logic methodology in order to alleviate the complexity of negotiation. The proposed negotiation agent model is particularly suitable to open environments, such as the Internet. The conventional methods, such as game theory, are incapable of handling an open environment where the information is sparse and full of uncertainty, while the fuzzy approaches are suitable to elegantly deal with this problem. The fuzzy logic based intelligent negotiation agent, presented in this thesis, is able to interact autonomously and consequently save human labor in negotiations. The aim of modeling a negotiation agent is to reach mutual agreement efficiently and intelligently. The negotiation agent is able to negotiate with other such agents, over various sets of issues, on behalf of the real-world parties they represent, i.e. it can handle multi-issue negotiation. The reasoning model of the negotiation agent has been implemented partially by using c# based on Microsoft .NET. The reliability and the flexibility of the reasoning model are finally evaluated. The results show that performance of the proposed agent model is acceptable for negotiation parties to achieve mutual benefits.
Modulation of glutamatergic synaptic transmission and plasticity by sigma receptor type 1 in the CA1 region of the hippocampus

description: The sigma receptor (sigmaR), once considered a subtype of opioid receptor, is now described as a distinct pharmacological entity. sigma1Rs are thought to be implicated in neuropsychiatric disorders such as schizophrenia, depression as well as in learning and memory. The modulation of N-methyl-D-aspartate receptor (NMDAR) by the sigma1R has been extensively documented; however, the mechanism through which the sigma1R modulates the NMDAR has been a mystery for almost two decades. Here, I report that sigma1R activation increases NMDAR responses and long-term potentiation (LTP) by blocking a small conductance Ca2+-activated K+ current (SK channels) known to shunt NMDAR responses. Therefore, the blockage of SK channels and the resulting increased Ca2+ influx through the NMDAR enhances NMDAR responses and LTP. These results emphasize the importance of the sigma1R as a post-synaptic regulator of synaptic transmission.

description: Issues continuously compete for attention in the news media and on social media. Climate change is one of the most urgent problems for society and (re)gained wide public attention in 2019 through the global climate strike protest movement. However, we hypothesize that the outbreak of the COVID-19 pandemic in early 2020 challenged the role of climate change as a routine issue. We use extensive news media and Twitter data to explore if and how the pandemic as a so-called killer issue has shifted public attention away from the issue of climate change in Switzerland. Results show that the climate debate fell victim to the impact of the COVID-19 pandemic in the news media and the Twitter-sphere. Given the vast dominance of the pandemic, there is a strong indication this finding applies similarly to various other issues. Additional hashtag co-occurrence analysis shows that some climate activists react to this development and try to connect the issue of climate change to the pandemic. We argue that suppression of climate change by the pandemic is a problem for its long-term resolution, as it seems to have turned climate change back into a struggling issue.
Evaluating the capability of FLO-2D and HEC-RAS-MDF to model the St. Sophia debris flow of Dec. 2003 at the St. Sophia Church Camp in Southern California

description: FLO-2D and HEC-RAS-MDF are applied to the St. Sophia debris flow event of December 2003. The FLO-2D model when applied to the location of the Church Camp results in an estimated flow depth of 16-18 m and a flow velocity of 16-18 m/s. The HEC-RAS-MDF model produced depths in the 3.0-5.0 m range and a velocity of 3.6 m/s. In this instance the HEC-RAS-MDF model provides results that are more in keeping with the field-based assessment of flow depths and velocities based on field mapping and reports regarding observed velocities. The depths and velocities that FLO-2D estimates are clearly excessive and likely due in part to the density values associated with the St. Sophia debris flow exceeding the operational and design capacity of the FLO-2D model, despite efforts to adjust for the higher flow densities. Efforts to further refine both models are ongoing.

description: Considerable efforts have been placed on the development of degradable microspheres for use in transarterial embolization indications. Using the guidance of the U.S. Food and Drug Administration (FDA) special controls document for the preclinical evaluation of vascular embolization devices, this review consolidates all relevant data pertaining to novel degradable microsphere technologies for bland embolization into a single reference. This review emphasizes intended use, chemical composition, degradative mechanisms, and pre-clinical safety, efficacy, and performance, while summarizing the key advantages and disadvantages for each degradable technology that is currently under development for transarterial embolization. This review is intended to provide an inclusive reference for clinicians that may facilitate an understanding of clinical and technical concepts related to this field of interventional radiology. For materials scientists, this review highlights innovative devices and current evaluation methodologies (i.e., preclinical models), and is designed to be instructive in the development of innovative/new technologies and evaluation methodologies.
Aspects of Lev Abramovich Mazel' thinspace's theory of integrated analysis.
Creators: name: Radonjic, Vladimir.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1992
Subjects: subject: Music.

description: In this thesis several aspects of the theory of integrated analysis of musical works of Lev Abramovich Mazel' (1907-) are presented and explicated. These aspects are dimensions of thematic structures, dynamics, timbre and texture, and melody. Mazel' segments his theory into different elements of music, presenting conceptions of each element in light of his integrated analytical method. The examination of these aspects affords a good cross-section of the entire theory of integrated analysis. The aspect of dimensions of thematic structures, in some ways the most original, reflects the structural and analytical tendencies of the theory of integrated analysis. Mazel' thinspace's discussion of dynamics, timbre, and texture is mainly concerned with perception and reflects those tendencies in the theory which examine the very nature of music as one of the arts. The treatment of melody combines both speculative and analytical tendencies. For Mazel' melody represents one of the most important elements of music. Integrated analysis represents an important achievement of Soviet theoretical thought in music. This thesis puts Mazel's theory of integrated analysis into historical perspective, indicating its origins, its context in Soviet music theory, and its place in Mazel' thinspace's overall output. Mazel' thinspace's formulation of the theory of integrated analysis represents only one of his contributions to Soviet musicological-theoretical thought. He is perhaps the most important living Soviet music theorist, and this makes a study of his works in the West all the more relevant.

description: Presently, the ATLAS experiment at the Large Hadron Collider is preparing for high-luminosity operation, which is scheduled to start after 2028. The inner detector of the ATLAS experiment will be replaced with an all silicon-based Inner Tracker which will have five layers of silicon pixels and four layers of silicon strips. These devices must operate efficiently, so a Detector Control System (DCS) will be implemented to monitor the electrical and thermal states of the detector. The DCS has front-end detector electronics and back-end user-interface components which require a communication interface layer that is based on a server-client model. This interface is provided by the Open Platform Communication United Architecture (OPC-UA) and allows for machine-to-machine communication that can be used to read data from any hardware/sensor. To achieve the desired functionality and monitoring capabilities of the detectors, an Application-Specific Integrated Circuit (ASIC) called AMACStar is used on the staves and petals that can communicate with an OPC-UA server connection. This document details the work on developing an OPC-UA server for the AMACStar ASIC and the results obtained at Brookhaven National Laboratory.
description: Neutrinos rarely interact with matter, owing to their charge neutrality and weak interaction, thus they can travel cosmological distances to reach Earth largely unhindered and can point back to their origin. However, this also means we require neutrino detectors to be of large volume in order to have a higher rate of neutrino detection. The interaction length for neutrinos at 40 TeV and above grows comparable to Earth's diameter, which makes Earth a suitable ultra-high-energy neutrino converter. Thus, terrestrial, sub-orbital and orbital neutrino detectors can detect signals from the extensive-air-showers induced by neutrinos. In this document, we describe the development of a simulation package nuPyProp, which simulates neutrinos (muon-neutrino and tau-neutrino) propagating through the Earth and interacting to produce the corresponding charged leptons (muons and tau-leptons). The code's outputs are lookup tables containing energy distributions and exit probabilities of the Earth-emerging charged leptons which can be used directly or as inputs to study extensive-air-showers produced by the emergent charged leptons. The uncertainty arising in the exit probability of tau-leptons due to the tau-leptons depolarization effect is also discussed, along with a methodology on calculating the depolarization effect.

Living with division: An analysis of the modern self and of contemporary democracy according to Marcel Gauchet.
Creators: name: Renault, Nancy L.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1998
Subjects: subject: Philosophy.

description: The following is an attempt to shed light on the continued role played by Otherness in a post-transcendental world as understood by French philosopher, Marcel Gauchet. Despite the end of religion as the organizational principle of society, he argues, are maintained two important forms of division. On the one hand, we will analyze how civil society is divided from political power and on the other how the modern individual is thought to be composed of a conscious and an unconscious element all the while attempting to draw parallels between the two levels of analysis.

description: Machine learning methods are increasing in popularity for biomedical research, and for many biostatisticians, fluency in machine learning methods is increasingly being expected of them. Hyperparameter optimization - informally referred to as ``tuning" - is critical in machine learning, but is often the most computationally intensive and time consuming part of the process. Aside from variations on grid search, many other approaches have been developed for tuning, but are often computationally intensive, fail to handle categorical hyperparameters, demonstrate performance that scales poorly in high-dimensions, and require tuning themselves.
description: In this dissertation, we present a two-step approach that first uses parametric smoothing splines to model the relationship between hyperparameters and performance metrics. We then use Thompson sampling, a Bayesian optimization technique, to explore the hyperparameter space and select the next grid point to evaluate based on the posterior probability of being best. The proposed method is compared to random grid search and other state-of-the-art methods on several real scenarios, and the results show that our approach outperforms popular optimizers in terms of speed and ultimate performance. Additionally, the proposed method is adapted for tuning a convolutional neural network in asynchronous parallel, and a stopping-rule heuristic is proposed with promising results.

Principles of accuracy, fairness and privacy under a new code
Creators: name: Briedis, Mark

Publisher: name: Swinburne
Year: 2024

description: Recent reports into regulation of the media recommend the creation of a 'news standards body' to oversee news providers and to create a new code. The new code should be founded on the public interest. It is an opportunity to recognize and entrench the legitimate interests of those affected by the presentation of news material. The fairness of news information should be based on the accuracy of the implied facts of news material. News providers will have freedom of speech in presenting opinion, but will be discouraged from presenting inaccurate material. With respect to privacy, the new code should strike a proper balance between the public interest in receiving information and the rights of the individual. The test for privacy invasion should be based upon the reasonable expectation of privacy.
