Exploring Machine Learning Models to Improve the Classification of Displaced Hadronic Jets in the ATLAS Calorimeter
Creators: name: De Schaetzen, Rodrigue
Publisher: name: The University of British Columbia
Year: 2020

description: The Large Hadron Collider (LHC) has yet to find new physics that could address the Standard Model's (SM) large open questions such as the composition of Dark Matter and the matter-antimatter asymmetry of the universe. There have been recent searches for Hidden Sector (HS) particles through the investigation of pair-production of neutral long-lived particles (LLPs) in proton-proton collisions. The ATLAS collaboration recently published results using a partial dataset from a search for paired LLP decays that produce displaced hadronic jets in the ATLAS calorimeter. Several classification models have been studied to identify these LLP decays, including boosted decision trees and LSTMs. In this analysis, 1D convolutional layers were added to an existing model architecture, which significantly improved the performance. Following hyperparameter optimization, the proposed model achieved a ROC AUC score of 0.97; a 10% relative improvement over the previous model.

description: Long duration energy storage systems with 8-12 hours of capacity are one of the best options to reduce the increasing curtailment of renewable energy, being able to provide intra-day storage. Among those systems, Carnot batteries operating with CO2 can be a promising solution due to the relatively high round trip efficiencies (up to 60%), being site-independent, including the possibility to store and sell both cold and hot thermal power in addition to electricity. In this work, the detailed sizing of the main components of a CO2 Carnot battery is proposed: in particular, an interesting and promising feature of the system is represented by in the adoption of the same heat exchangers during the charging and the discharging phase, while the cold and hot storage systems are inspired by the commercial solution proposed by Echogen Power Systems. Specifically, the hot storage consists of two heat transfer fluid loops: a pressurized water loop and a diathermic oil loop, requiring two different insulated tanks, whereas the cold storage is based on an ice slurry tank. A routine in MATLAB has been developed to properly design the system and optimize its main variables to maximize the round-trip efficiency and minimize the storage costs, but also including the calculation of the levelized cost of storage. The battery is simulated with a cold storage at 0°C and hot storage between 71.6°C and 293.7°C, with the cycle maximum pressure of 250 bar and a round-trip efficiency of 54.6%. The specific capital cost of the system is 2033 €/kWel,ch, with the largest share being the storage systems. The levelized cost of storage is estimated around 0.1 and 0.3 €/kWh, depending on the electricity selling price, and a relatively large internal temperature difference in the hot storage (20°C) is suggested for these systems.

description: To explore the potential of oxy-fuel technology, a detailed thermodynamic analysis is performed for four different oxy-fuel combustion cycles: the SCOC-CC, Matiant cycle, S-Graz cycle, and Allam cycle. Based on the literature data, these thermal cycles are modeled and simulated at full load using commercial software Aspen Plus with the same input and boundary conditions. The results show that the Allam cycle and S-Graz reach the highest net energy efficiency with 56.04% and 53.19%, respectively. The Matiant cycle and SCOC-CC have lower efficiencies at 50.02% and 45.23%, respectively. The exergy efficiency is also higher for the Allam cycle (52.87%) and the S-Graz cycle (50.18%). Moreover, the CCS efficiency penalty is comparatively higher for S-Graz, SCOC-CC, andMatiant, with 3.88%, 1.78%, and 1.70%, respectively. This is primarily because of the lower condenser pressure than the Allam cycle, which has a penalty of 0.42%. The ASU efficiency penalty is consistent at 10.31% for all cycles due to the same delivery pressure, flow rate, and oxygen purity. However, in the Allam cycle, it is marginally higher by 0.71 ppt due to an extra oxygen compressor. The results also indicate that the turbine main parameters, such as inlet temperature, inlet pressure, outlet pressure, and condenser pressure, strongly influence the system overall performance. The Allam cycle generally stands out for its high thermal efficiency and simple configuration.

Synaptic silencing of fast muscle is compensated by rewired innervation of slow muscle

description: For decades, numerous studies have proposed that fast muscles contribute to quick movement, while slow muscles underlie locomotion requiring endurance. By generating mutant zebrafish whose fast muscles are synaptically silenced, we examined the contribution of fast muscles in both larval and adult zebrafish. In the larval stage, mutants lacked the characteristic startle response to tactile stimuli: bending of the trunk (C-bend) followed by robust forward propulsion. Unexpectedly, adult mutants with silenced fast muscles showed robust C-bends and forward propulsion upon stimulation. Retrograde labeling revealed that motor neurons genetically programmed to form synapses on fast muscles are instead rerouted and innervate slow muscles, which led to partial conversion of slow and intermediate muscles to fast muscles. Thus, extended silencing of fast muscle synapses changed motor neuron innervation and caused muscle cell type conversion, revealing an unexpected mechanism of locomotory adaptation.

description: We use the relativistic mean field (RMF) model to conduct a thorough analysis of the ground-state properties of $^{67\text{--}80}$Ge nuclei. Binding energies and neutron skin thicknesses are computed for a total of 14 neutron-rich Ge isotopes. This study provides a comprehensive overview of the RMF model's explanation of nuclear ground-state properties. Furthermore, we examine the $\log ft$ values of the allowed $β^\pm$ decays and electron/positron capture rates on Ge isotopes in the mass region $A = 67\text{--}80$. The proton-neutron quasiparticle random phase approximation (pn-QRPA) method was employed to calculate the $β$-decay properties of selected Ge isotopes. The calculated $\log ft$ values show good consistency with the measured data. The predicted $β$-decay half-lives are within a factor of 2 of the measured values. For high temperature and density conditions in the core of massive stars, the calculated pn-QRPA stellar rates are up to an order of magnitude larger than the independent shell model rates. The findings reported in this study could be valuable for simulating the late-stage stellar evolution of massive stars.

description: High heat fluxes from nuclear fusion pose a challenge for heat exchange. Supercritical CO2 and micro-channel heat exchangers offer a way to solve this challenge, however heat transfer correlations for supercritical fluids do not necessarily carry over to higher heat fluxes. This experimental study investigates a promising geometry of S-Shaped fin microchannel heat exchangers at heat fluxes up to 1MW/m2, 10 times hotter than previously tested in the literature. A high temperature test section was heated under laser diodes to represent the heat flux from fusion. A conjugate CFD study was performed, but this did not match the experimental temperatures well. To remedy this, an FE model was made, in which the heat transfer profile from CFD was scaled by a constant factor, giving better agreement with experimental temperatures. A thermal resistance network was developed, and the unknown heat transfer coefficient was varied to minimise the error between the predicted temperatures and experimental ones. This gave heat transfer coefficients that matched well with correlations in the literature, at these elevated heat fluxes. This implies that the design could be used effectively for the heat fluxes found in the blanket of a fusion reactor.

description: Mental rotation (MR) and perspective taking (PT) are important spatial abilities and predictive of performance in other cognitive domains. Yet, age-appropriate measures to assess these spatial abilities in children are still rare. This study examined psychometric properties of four MR tasks in 6- to 9-year-olds (N = 96). Two were developed specifically for children and two were based on established assessments for adults; one of each was a computerized and one was a paper–pencil task. Furthermore, spatial perspective taking (PT)—a different but closely related ability—was assessed to determine discriminant validity. Factor analyses showed that all MR tasks loaded on one single factor, with PT only loading weakly on the same factor, suggesting high construct validity. The computerized task for adults showed moderate factor loadings, constituted its own (but correlated) factor when a two-factor solution was forced, and showed the lowest reliabilities, suggesting that it was very difficult for children. On average, the new MR tasks had good to excellent reliabilities, differentiated well between age groups, and proved to be well-suited to assess MR in this age range. The PT task also showed good reliability and a steep developmental progression. Relations to verbal skills, gaming experience, and TV consumption are discussed.
Lived experiences in museums: Engaging visitors’ hearts and minds

Publisher: name: University of Leicester

Subjects: Uncategorized

description: In this PhD thesis, I analyse the different ways in which museums incorporate experiences and knowledge we call lived experiences, in museums dealing with difficult subject matters. I define lived experiences as non-formal knowledge based on people’s own empirical experiences, ways of life or local knowledge. The incorporation of lived experiences in museums is often a result of collaboration between museums and their communities, but their use can also give communities a direct voice in museum displays and programmes that do not depend on formal collaborations of this kind. The use of video- and audio-stories, where victims of war, conflict, and other difficult subjects present their stories and experiences, are examples of lived experiences used in museums. Although I am generally interested in how lived experiences are used in museums, the focus of my thesis is primarily on the impact these have on museum visitors. In my research, I study two cases which show how lived experiences are used in curatorial work and in educational programmes in institutions that can be defined as memory museums, aiming at counter prejudices in visitors and in wider society. The selected museum cases are The Centre of 22nd of July in Norway, and Museo Casa de la Memoria in Colombia. I give examples of how these museums use lived experiences in different ways, and how this is perceived and interpreted, primarily by museum visitors, but also by victims of war and violence. The findings of this research suggest that the incorporation of lived experiences in museum work adds an important dimension to the programmes and exhibitions we, as museums, present to our visitors. The use of lived experiences tends to evoke affect and emotions - something that makes visitors identify with individuals and, hopefully, also prompts them ultimately to act against injustices, violence, and prejudices.

description: This paper is dedicated to the performance map computation of centrifugal compressors operated with carbon dioxide at supercritical states (sCO2) and inlet conditions in the vicinity of the critical point. Three-dimensional computational fluid dynamics (3D-CFD) simulations are utilised. First, different approaches to model two-phase flows are reviewed. Second, the impact of two-phase flow on the speed of sound and the choking limit is further investigated. The flow through Laval nozzles is analysed to simplify the problem to its fundamental aspects. The 3D-CFD calculations match well with the ones conducted with simple onedimensional CFD programs and the theory of equilibrium phase change. Third, the throttle curve of an industrial-scale centrifugal compressor is computed and compared to the one for air. Total inlet conditions are supercritical in the so-called liquid-like region. A considerable shift of the choking line towards lower flow coefficients is found. The reason for this shift is a drop in the speed of sound when bubbles are formed in the liquid, and a twophase flow is established while the flow is accelerated around the compressor’s leading edge. Finally, a log(p)-h diagram is provided, enabling a quick assessment of the risk of two-phase flow in centrifugal compressors.

title: A global policy in local context/a local policy in global context: investigating dual VET youth transitions in Coahuila, Mexico
Creators: name: Vanderhoven, Ellen
Publisher: name: University of Glasgow
Year: 2024

description: In recent decades, a global agenda has developed to promote apprenticeships as an educational policy solution of near universal relevance. Among such models, dual vocational education and training (dVET) is often considered the ‘gold standard’. As such, there has been intense activity to ‘transfer’ dVET from DACH countries (Austria, Germany, Switzerland) to elsewhere, including many low- and middle-income country (LMIC) contexts. Mexico is one such LMIC to have adopted dVET, in a process explicitly brokered by German co-operation actors. In 2013, the Modelo Mexicano de Formación Dual (MMFD) was piloted in 11 states, expanding over the proceeding decade.

This thesis identifies and addresses important gaps in research knowledge about ‘transferred’ dVET models of this kind, advancing theory about how dVET functions in LMIC contexts based on empirical research that centres the experiences and insights of young policy participants. Three waves of qualitative longitudinal interviewing were conducted with 16 MMFD participants (n=48) in the state of Coahuila, Mexico between February 2020 and February 2022. The Grammars of Youth framework developed by Ana Miranda and colleagues at FLACSO Argentina is used to conceptualise and explain the structures and strategies that mediate MMFD youth transitions.

Theoretically, the thesis extends the Grammars of Youth framework to develop a typology of grammars – i.e. structures – that mediate youth transitions, namely: subjective, temporal, and locational grammars. Subjective grammars relate to the influence of young people’s intersecting social identities, temporal grammars relate to the specific time context in which youth transitions unfold, producing distinct cohort effects, and locational grammars relate to the multi-scalar sociospatial contexts in which young people construct their transitions. In addition, this thesis also explains how and why MMFD participants employ different youth pragmatics – i.e. strategies – in their transitions and, thus, how grammars and pragmatics co-construct one another over time.

This rich and contextualised understanding of MMFD youth transitions is used to analyse MMFD policy features and suggest future policy directions to make dual training more effective and equitable. Furthermore, the ‘local’ case of the MMFD is used to scrutinise the discursive claims of the ‘global apprenticeship agenda’. Theories and assumptions about how apprenticeships function are found to be troubled by the contextual realities in which policy participants live, particularly in LMICs. These inconsistencies contain important risks related to inequalities, exploitative practices, and programme ineffectiveness. Greater attention to the lives and desires of young people as the embodied protagonists of dVET is argued to be a crucial means of counteracting those risks and pursuing an expanded vision of what vocational education can achieve.

Digital Diaspora : Investigating Identity in ‘subtle asian traits’
Creators: name: Wong, Ervin
Publisher: name: The University of British Columbia
Year: 2021

description: The meteoric rise of subtle asian traits (SAT), a Facebook group centered around sharing memes and experiences unique to Asian individuals who balance their cultural influences with that of the Westernized society around them, has surely impacted how racial and ethnic identity is represented and engaged with. Its presence as a digital space nuances this phenomenon even further. How is a collective Asian diasporic identity understood and represented on SAT? To that end, how does this collective identity that SAT proposes inform or relate to members’ personal racial or ethnic identities? This research draws from seven semi-structured qualitative interviews conducted with individuals who are members of subtle asian traits among other offshoot groups. A range of opinions were expressed about the community that is cultivated on SAT, of which inclusive and exclusionary aspects were cited as shaping a certain group racial identity. Participants’ personal relevance to this group identity similarly covered a range of attitudes towards SAT. The digital nature of the space is also examined in its influence and facilitation of the identity work that occurs. Overall, this analysis uncovers how SAT as a space drives racial and ethnic identity to the forefront of members’ minds and compels them to assert these identities unapologetically in contemporary and digital formats.

description: CO₂ is commercially available in various purity grades, typically containing impurities such as air components: nitrogen, oxygen, and water. This study examines how impurities affect the performance of a supercritical CO₂ (sCO₂) system. The analysis focuses on a sequential heating architecture under both supercritical and transcritical regimes. A multi-fluid mixture model was used to analyze the thermophysical properties of the investigated mixtures. The parametric analysis indicates that impurities strongly alter the thermodynamic properties of CO₂, such as specific heat, viscosity, and density, and significantly impact cycle performance. By analyzing twenty CO₂-based mixtures with varying purity levels and chemical compositions, the study reveals that impurities particularly affect the density of CO₂, leading to performance degradation. The results show that system performance is highly sensitive to CO₂ purity levels. Mixtures over 99.8% purity exhibited minimal performance losses, with net power reductions limited to 2%. Mixtures with 99% purity experienced losses ranging from 5% to 11%, while mixtures with 96% purity suffered reductions of up to 30%. These findings highlight the importance of analyzing impurity levels and compositions in CO₂ supply for sCO₂ systems, as they significantly influence efficiency and operational feasibility. The results also highlight the need for impurity analysis tailored to specific system architectures and operating regimes.

description: Finding the optimal tour that visits a series of locations sequentially, such as going for errands, is an everyday task formally known as the travelling salesperson problem (TSP). In this article we focus on the understudied type of multilevel or M-TSP, which take place in a multilevel environment, like a building. In a TSP, the number of alternative tours the decision-maker needs to consider is given by the factorial of the locations to visit; hence a 3-target TSP has 6 alternatives and a 12- target TSP has 479 million. Considerable research has focused on combinatorial optimisation algorithms for TSPs, and in the cognitive sciences there has equally been a sustained interest on how various foraging species and humans achieve remarkably optimal performance. However, research has primarily studied planar environments, and it is unclear how people will combine horizontal and vertical spatial information to make navigational decisions in a multilevel TSP. In this study, we asked 41 participants to first learn the locations of 12 shops (targets) in a multilevel building, and then complete a structure mapping task and two open 8-target M-TSP tasks (more than 40.000 alternatives). Using bayesian methods for mixed effects modelling, we show that human performance in navigational M-TSPs is lower than this of Euclidean TSPs, and we differentiate between the choice of tour (visit sequence) and transitions (local wayfinding). Our results show an effect of horizontal versus vertical learning. We also found that performance in navigational TSP are a composite of global and local decision making, and the people adaptively employ a path-based, rather than euclidean, measure of distance when this is ecologically relevant. Overall we provide multiple sources of evidence for the horizontal bias theory both in mental representations and wayfinding behaviour. This study contributes to current knowledge of mental representations 3D space and is the first huto provide human data on an multilevel TSP. More generally, these findings have implications for our understanding of wayfinding and navigational behaviour in multilevel environments.

description: Current large speech language models are mainly based on semantic tokens from discretization of self-supervised learned representations and acoustic tokens from a neural codec, following a semantic-modeling and acoustic-synthesis paradigm. However, semantic tokens discard paralinguistic attributes of speakers that is important for natural spoken communication, while prompt-based acoustic synthesis from semantic tokens has limits in recovering paralinguistic details and suffers from robustness issues, especially when there are domain gaps between the prompt and the target. This paper unifies two types of tokens and proposes the UniCodec, a universal speech token learning that encapsulates all semantics of speech, including linguistic and paralinguistic information, into a compact and semantically-disentangled unified token. Such a unified token can not only benefit speech language models in understanding with paralinguistic hints but also help speech generation with high-quality output. A low-bitrate neural codec is leveraged to learn such disentangled discrete representations at global and local scales, with knowledge distilled from self-supervised learned features. Extensive evaluations on multilingual datasets demonstrate its effectiveness in generating natural, expressive and long-term consistent output quality with paralinguistic attributes well preserved in several speech processing tasks.

description: Black silicon (b-Si) has been receiving a great deal of interest for its potential to be used in applications ranging from sensors to solar cells and electrodes in batteries due to its promising optical, electronic and structural properties. Several approaches have been used to demonstrate the possibility of producing application quality b-Si, which also exhibits light emission properties. The photoluminescence is a useful technique to identify recombination pathways and thus enable us to optimize device quality. In this work, we report the results of the radiative recombination dynamics in b-Si produced by a technique involving thermal oxidation, photoresist coating and chlorine plasma etching. An ultrafast blue luminescence component competing with non-radiative recombination at surface defects was identified as no-phonon radiative recombination. This component involves two decay processes with a peak energy at around 480 nm, which have the fast component of about 15 ps followed by a component of around 50 ps lifetime. The emission exhibits a slow process in red spectral region with time constant of 1500 ps. When the surface is smoothed, the lifetime of carriers increased up to 4500 ps and the emission peak blue shifted indicating downsizing in dimensions. The results are correlated with transmission electron microscopy, localized vibrational modes and spectroscopic ellipsometry and interpreted through the presence of quantum

description: Der auch schon von Huizinga beobachtete Spielverlust in unseren Gesellschaften, der sich heute noch verschärft darstellt, würde besondere Aufmerksamkeit in der Sozialisation und im Erziehungssystem benötigen. Jedoch hat das Spiel zusehends die zwar funktionale, aber miniaturisierte Rolle, andere Kulturtechniken zu unterstützen. Im Beitrag werden die kulturellen, sozialen und rituellen Strukturen des Spiels untersucht, die mit der Ermöglichung von Exploration verbunden sind, und die sein Potenzial für Lernen und Bildung ausmachen, wobei die Spielfähigkeit selbst als die entscheidende Kulturtechnik in den Blick kommt. Es wird untersucht, wie die Exploration im Spiel unter Kindern sich strukturiert, und welche kulturellen und individuellen Motive bei der Begleitung des Spiels durch die Lehrpersonen dazu führen können, dass es oftmals eher zur Disziplinierung des Spiels kommt als zur erfahrungsbasierten, gleichrangigen Auseinandersetzung. Alternativen werden skizziert. (DIPF/Orig.)

description: The silicon suboxide SiOx (x<2.0) offers promising industrial application possibilities ranging from electrodes in lithium-ion batteries, which are used widely in electrical vehicles and portable devices to sensing applications. Therefore, a low cost, environmental friendly and high performance silicon oxide materials are required for an appropriate operation of any electronic gadget. In this work, we report on the physical and electrical properties of a suboxide layer of up to 1 μm, which was grown on silicon during the formation of a dielectric layer, namely the ammonium silicon hexafluoride. It is a stable oxide exhibiting light emission from 400 nm to 1700 nm offering scalable and cost-effective large area processing capability. The measurement results reveal interesting properties, which are required to be understood clearly before proceeding with any suitable application. The results have been analyzed using state-of-the-art physical and electrical characterization techniques such as ellipsometry, AFM, SEM, FTIR, photoluminescence lifetime and resistive switching measurements to determine structural, optical and electrical properties. At 300 K the carrier lifetime measurements reveal the lifetime values ranging from about few tens of picosecond up to 4500 picoseconds. Scanning probe analysis indicate a surface roughness of about 30 Angström. Resistive memory forming was observed also in these layers at relatively low power thresholds. We provide a comprehensive description of the physical and electrical properties in order to clarify the origin of the observed features. The wavelength dependent real ε_1 (ω) and the imaginary ε_2 (ω) dielectric functions provided useful insights on optical properties. A lookout is given for the possible applications of this special SiOx dielectric oxide layer.

description: Compressors operating with carbon dioxide near the critical point experience complex aerothermodynamic phenomena, where deviations from perfect-gas similarity and two-phase flow effects dominate. Existing models inadequately capture the impact of intake thermodynamic conditions on the choked flow rate, leaving a gap in predictive capabilities for these machines. This work addresses this gap by deriving a correlation to predict the choked flow rate as a function of two generalized parameters: the cavitation/condensation parameter and the isentropic pressure-volume coefficient, which describe two-phase and non-ideal effects. A database of 100 speedlines, generated through CFD simulations with varying thermodynamic conditions and fixed peripheral Mach number, was used to train a symbolic regression algorithm based on gene expression programming. This method was chosen to derive an explicit, easy-to-use analytical expression without assuming a priori functional forms. Results showed that the choked flow rate could vary from 90% to 155% of the nominal value depending on thermodynamic conditions, highlighting the dominant role of the two parameters. The derived correlation demonstrated trends consistent with CFD predictions, with an accuracy of ±3 percentage points for most cases. However, an a-posteriori validation against varying peripheral Mach numbers and an alternative impeller geometry revealed significant discrepancies, underscoring the interplay between thermodynamic conditions, geometry, and aerodynamics. This analysis showed that the peripheral Mach number and the geometric features influence choking behavior unpredictably, limiting the correlation's general applicability. While the proposed correlation is not adequate for quantitative scaling across designs, it provides preliminary insights into qualitative trends. For accurate predictions, high-fidelity CFD remains necessary, highlighting the inherent challenges of universal scaling for near-critical operations in sCO₂ compressors.
