description: Chloride-induced corrosion of reinforcing steel in concrete is a worldwide problem. In order to predict how chlorides penetrate in concrete and how other ionic species in con-crete pore solution affect the penetration of chlorides, this thesis presents a numerical study on multi-phase modelling of ionic transport in concrete dominated by migration process. There are many advantages in rapid chloride migration test (RCM) method and numeri-cal approach. However, most of models in the literature predicting chloride diffusivity in concrete are diffusion models, which not consider the action of externally applied electric field. In view of this, the specific aim of this thesis is to develop a rational nu-merical migration model to simulate chloride migration tests. By using this model, the diffusion coefficient of chlorides in concrete will be efficiently predicted. Furthermore, other mechanisms of ionic transportation in composite materials can be scientifically in-vestigated in the meantime. In most existing work, researchers tend to use the assumption of electro-neutrality con-dition, which ensures that no external charge can be imported (Bockris and Reddy, 1998), to determine the electrostatic potential within concrete as well as considering a 1-D problem with only one phase structure and single species (i.e. the chlorides) for pre-dicting the ionic migration. In contrast, this thesis presents a number of sets of multi-phase migration models in more than one dimension and uses the Poisson’s equation for controlling the multi-species interactions. By solving both mass conservation and Pois-son’s equations, the distribution profiles of each ionic species and electrostatic potential at any required time are successfully obtained. Some significant factors, i.e. the influ-ence of dimensions, aggregates, interfacial transition zones (ITZs), cracks and binding effect have also been discussed in detail. The results reveal a series of important features which may not be seen from existing numerical models. For quantitative study, this thesis also provides the prediction method of chloride diffu-sivity not only by the traditional stationary diffusion models but also by the migration models presented in the thesis. The obtained results are compared with three proven analytical models, i.e., Maxwell’s model (Dormieux and Lemarchand, 2000), Brug-geman’s equation (Bruggeman’s, 1935) and the lower bound of the effective diffusion coefficient proposed by Li et al. (2012) as well as validated against experimental data sets of an accelerated chloride migration test (ACMT) brought by Yang and Su (2002).

description: We develop a conditional sampling scheme for pricing knock-out barrier options under the Linear Transformations (LT) algorithm from Imai and Tan (2006). We compare our new method to an existing conditional Monte Carlo scheme from Glasserman and Staum (2001), and show that a substantial variance reduction is achieved. We extend the method to allow pricing knock-in barrier options and introduce a root-finding method to obtain a further variance reduction. The effectiveness of the new method is supported by numerical results.
Stiffness of mouse aortic elastin and its possible relation to aortic media structure
Creators: name: Clark, Trisha Elaine
Publisher: name: University of British Columbia
Year: 2013

description: Aortic elastin allows arterial expansion on systole and subsequent elastic recoil during diastole, providing crucial capacitance and associated dampening of the cardiac pressure pulses. The structure and mechanical properties of the aortic wall are not uniform along its length due to the varying hemodynamic conditions to which it is exposed, but elastin’s contributions to this variation are not well studied. The artery wall is a composite of two main structural proteins: elastin and collagen. Autoclaving an intact aorta removes the collagen and produces a mechanically competent vessel consisting of purified elastin, which can be used to study elastin’s contribution to arterial mechanics. Although it is generally assumed that elastin’s material stiffness is constant, a recent study in pigs found that it increased 30% along the thoracic aorta. I hypothesized that this increase in elastin stiffness was caused by a difference in the amount of elastin, the amount or orientation of the interlamellar elastin fibres (IEL), the partitioning of elastin between its three forms, the thickness or orientation of the elastic lamellae, or the number of elastin struts. Uniaxial tensile testing of autoclaved mouse aortas showed that elastin’s stiffness is 43% lower in abdominal aortas compared with thoracic aortas, allowing the mouse aorta to be used as a model to investigate this surprising variation in elastin stiffness. Elastin structure within the thin mouse aortic walls was imaged with multiphoton laser scanning microscopy to identify any differences in the elastin structure that could cause the variation in stiffness. No difference was found between the elastin structure of the thoracic and abdominal aortas that could account for the difference in elastic modulus; however, I was not able to count the elastin struts or measure the elastin fibre packing density in the elastic lamellae and so could not reject these two hypotheses.

description: Theoretical models predict that some of the first stars ended their lives as extremely energetic pair-instability supernovae (PISNe). With energies approaching 10^53 ergs, these supernovae are expected to be within the detection limits of the upcoming James Webb Space telescope (JWST), allowing observational constraints to be placed on the properties of the first stars. We estimate the source density of PISNe using a semi-analytic halo mass function based approach, accounting for the effects of feedback from star formation on the PISN rates using cosmological simulations. We estimate an upper limit of ~0.2 PISNe per JWST field of view at any given time. Feedback can reduce this rate significantly, e.g., lowering it to as little as one PISN per 4000 JWST fields of view for the most pessimistic explosion models. We also find that the main obstacle to observing PISNe from the first stars is their scarcity, not their faintness; exposures longer than a few times 10^4s will do little to increase the number of PISNe found. Given this we suggest a mosaic style search strategy for detecting PISNe from the first stars. Even rather high redshift PISNe are unlikely to be missed by moderate exposures, and a large number of pointings will be required to ensure a detection.

description: We investigate the possibility that a massive weakly interacting fermion simultaneously provides for a dominant component of the dark matter relic density and an invisible decay width of the Higgs boson at the LHC. As a concrete model realizing such dynamics we consider the minimal walking technicolor, although our results apply more generally. Taking into account the constraints from the electroweak precision measurements and current direct searches for dark matter particles, we find that such scenario is heavily constrained, and large portions of the parameter space are excluded.

description: We propose an extension of the 4+1D SU(5) domain-wall braneworld of Davies, George and Volkas which includes the addition of a discrete A(4) flavor symmetry. We show that lepton mixing and light Majorana neutrino masses can be generated from the additional A(4) physics while at the same time sufficient parameter freedom can be maintained in the charged fermion sector to produce charged fermion masses and quark mixing naturally from the split fermion mechanism. Importantly, we show that the vacuum realignment problem typical of discrete flavor symmetry models of quark and lepton mixing can be solved by separating the appropriate flavons in the extra dimension, leading to exponentially sensitive suppression of the operators responsible for vacuum realignment.

description: Research on camel milk and urine (CMUR) has gained significant attention because of its nutritional and medicinal applications. The aim of this study was to conduct a bibliometric analysis of the CMUR from 1947 to 2023. Following PRISMA rules, the Scopus database was used to extract 1338 English-language studies, which were analyzed using Scopus Analytics, Bibliometrix, and VOSviewer. The findings indicated that 7.78% of studies focused on camel urine within the CMUR domain. The analysis showed a steady increase in the number of publications over 77 years (R-squared = 0.8308). The CMUR encompasses a wide range of research disciplines, with particular emphasis on the agricultural and medical fields. Saudi Arabia is the top producer of CMUR, with the Journal of Camel Practice and Research being the most prolific source. King Saud University contributed 103 documents to the CMUR, making it the most prolific institution globally. The co-word analysis identified seven prominent research themes within the CMUR, which can be further categorized into four distinct clusters. Notably, ‘Probiotics’, ‘Anti-inflammatory’, and ‘Diabetes’ emerged as trending subjects. The analysis of the CMUR yielded significant insights into the present research trends, identified gaps in the existing knowledge, and provided valuable recommendations for future investigations.

description: We report a versatile and practical approach for generating high-quality polarization entanglement in a fully guided-wave fashion. Our setup relies on a high-brilliance type-0 waveguide generator producing paired photon at a telecom wavelength associated with an advanced energy-time to polarisation transcriber. The latter is capable of creating any pure polarization entangled state, and allows manipulating single photon bandwidths that can be chosen at will over five orders of magnitude, ranging from tens of MHz to several THz. We achieve excellent entanglement fidelities for particular spectral bandwidths, i.e. 25 MHz, 540 MHz and 100 GHz, proving the relevance of our approach. Our scheme stands as an ideal candidate for a wide range of network applications, ranging from dense division multiplexing quantum key distribution to heralded optical quantum memories and repeaters.

description: Restorative justice is a term used to describe an array of practices growing in popularity as alternatives to the formal criminal justice system. Although restorative justice theory and process outcomes have been studied extensively, there has been minimal qualitative analysis in this field towards understanding how and why these practices work. This gap in knowledge led Choi (2008) to describe restorative justice as a “black box”. This research seeks to illuminate the ‘black box’ through a qualitative study of experiences of some of the practitioners who guide restorative justice with ‘serious’ cases. These participants described a great passion for restorative justice and a commitment to reflexive practice. They were willing to critically explore their own experiences, the processes they work within, and the theories and ethics of this evolving field. Emergent themes included: The importance of the impact of crime, experiences illuminating the ‘black box’, the role of mentorship in restorative justice, experiences of witnessing stories, the importance of relationships and communities, questions of standards and standardization, and the misuse of power in restorative justice. A dominant over-arching theme expressed by all participants was a caution that as restorative justice moves towards legitimization it should do so ‘in a good way’ by honouring the values and ethics it was founded upon.
title: Integrated Photovoltaic with Reversible Proton Exchange Membrane Fuel Cell-based Building Cladding Systems for Hydrogen and Oxygen Production
Creators: name: Zhang, Jingshi
Publisher: name: Georgia Institute of Technology
Year: 2025

description: The latest data from the US Energy Information Administration (EIA 2022) shows that energy consumption from buildings accounted for 37 percent of total energy consumption, of which 79 percent is derived from fossil fuels that cause 73 percent of greenhouse gas emissions. According to the US government (US Department of State and US Executive Office of the President 2021), there is a need to investigate renewable energy and carbon neutralization. This paper reports on an ongoing doctoral project in architecture that examines the application of reversible fuel cells in buildings and proposes a system for integrating photovoltaics with reversible fuel cells into building envelopes. This system has been designed to produce clean energy in the form of electricity and hydrogen, as well as oxygen for buildings to improve indoor air quality. Hydrogen is regarded as a possible energy storage medium for transitioning the world to a zero-carbon environment. Among six common fuel cells, proton exchange membrane fuel cells (PEMFCs) are straightforward to use and lead to a relatively higher energy conversion rate of 40–60% (EERE n.d.). Researchers have previously studied some electrochemical applications for building energy generation and storage. In this research, we aimed to explore the potential of reversible proton exchange membrane fuel cells for building skin applications by constructing a physical prototype and measuring its efficiency. To confirm the potential of reversible fuel cells for building skin applications, our team constructed an initial prototype of a reversible PEMFC-based cladding system. The prototype was 15.24 cm × 15.24 cm (6 in. × 6 in.) and contained four photovoltaic cells on the exterior side and four reversible PEMFCs on the interior side. The independent variable was radiation, and the dependent variables included oxygen volume, hydrogen volume, and energy conversion efficiency. The irradiance on the day of the experiment was measured at 156.6 W/m2 (49.6 Btu/(hr.ft2)). The hydrogen energy output of the system was determined to be 15.7 W/m2 (5.0 Btu/(hr.ft2)), yielding an energy conversion rate of 8.76 percent. The energy conversion rate of a traditional PV system with batteries is 15–20 percent. While the proposed system cannot currently compete with commercial PV-battery systems, energy conversion efficiency may be improved through future research. In addition, the scalability of reversible fuel cell storage is better than traditional batteries, as a byproduct of the proposed system, oxygen can be introduced into HVAC systems in buildings to improve indoor air quality. We envision a future in which diverse and clean energy generation and storage technologies have been adopted in building skins to help supplement or replace traditional sources of energy.

description: We introduce a "water retention" model for liquids captured on a random surface with open boundaries, and investigate it for both continuous and discrete surface heights 0, 1, ... n-1, on a square lattice with a square boundary. The model is found to have several intriguing features, including a non-monotonic dependence of the retention on the number of levels in the discrete case: for many n, the retention is counterintuitively greater than that of an n+1-level system. The behavior is explained using percolation theory, by mapping it to a 2-level system with variable probability. Results in 1-dimension are also found.

Essays on macroeconomics
Creators: name: Gao, Xiaodan
Publisher: name: University of British Columbia
Year: 2013

description: This dissertation studies two important topics in macroeconomics. The first topic is on the corporate cash hoarding. The first two chapters analyze the cash-inventory tradeoff from two different but complementary perspectives and shed light on the causes of cash hoarding. The second topic is international business cycles. A new feature of capital market is introduced into a standard international business cycle model to account for the disconnect between theory and data. The first chapter proposes an explanation for the joint dynamics of cash and inventory -- the adoption of the Just-in-Time (JIT) system. I start by demonstrating the importance of JIT in shaping corporate cash. I then develop a dynamic stochastic model to analyze the mechanisms and quantify their impacts. In the model, both cash and inventory can serve as working capital. As firms switch over from the traditional operating system (Just-in-Case, JIC) to JIT, they allocate the resources freed up from inventory to cash, in order to ensure smooth transactions with suppliers. On average, this switchover accounts for 45% and 69% of the observed cash increase and inventory decline respectively. The second chapter provides a complementary explanation for the cash-inventory joint dynamics. It models inventory as a reversible store of liquidity and studies the tradeoff between cash and inventory when a firm manages its liquidity needs. I argue that two key determinants of a firm's resource allocation decision are its market power and its exposure to risk. In the model, firms with lower market power and firms operating in riskier environments rely more heavily on cash rather than inventory. Model implications are supported by data. The third chapter studies the role of limited asset market participation (LAMP) in explaining international business cycles. We show that when LAMP is introduced into an otherwise standard model of international business cycles, the performance of the model improves significantly, especially in matching cross-country correlations. To perform formal evaluation of the models we develop a novel statistical procedure that adapts the statistical framework of Vuong (1989) to DSGE models. Using this methodology, we show that the improvements brought out by LAMP are statistically significant.

title: DEPRECATED: SKILLS ANALYSIS ABOARD SHIPS
Creators: name: LAWRENCE, DAVID PETER
Publisher: name: University of Plymouth
Year: 1988

description: This thesis presents a detailed description, based upon the literature available, of shipboard organization and social structure, together with a descriptive summary of the dynamic environment in which ships operate. The literature relating to job and task analysis is also reviewed and examined for its relevance to shipboard studies. A picture emerges of an industry being forced by technical, social, legal and economic factors to rationalize the use of its manpower resources. It is found that many authors propose the adoption of a matrix manning model. The thesis is proposed that matrix manning is technically viable as a method of manning all types of merchant vessels. A methodology is developed which allows identification, observation, recording and analysis of shipboard operational functions. The methodology involves a unique amalgamation of Fine & Wiley's Functional Job Analysis with ratings of the frequency, criticality and difficulty of functional performance. The identified functions necessary for ship operation are detailed. A rationale is included for the selection of ship types used for data collection during the research project. The process of observation and shipboard data gathering is described. The problems which arose with regard to data collection are mentioned together with their methods of solution. The collected results are analyzed and show that there are three technical classes of ships for consideration when studying manpower problems. General concepts of function significance and complexity are derived from the results. These concepts are used to support the argument that there exist two levels of functional performance aboard ships. These separate performance levels are shown to be essential to the introduction of matrix manning. The concept of dual level performance is merged with the information from the function profiles (which illustrate the qualitative nature of shipboard work). This combination of data is then used to demonstrate that shipboard functions may be reclustered in an innovative fashion which supports the introduction of matrix manning. Finally, the concepts of function significance and complexity are shown to have important implications in the field of manpower studies. In particular it is shown that conventional linear manpower policies are inadequate and that a two dimensional structure provides greater insight into the successful utilization of human resources.

description: We consider the see-saw mechanism within a non-supersymmetric SO(10) model. By assuming the SO(10) quark-lepton symmetry, and after imposing suitable conditions that ensure that the right-handed (RH) neutrino masses are at most mildly hierarchical (compact RH spectrum) we obtain a surprisingly predictive scenario. The absolute neutrino mass scale, the Dirac and the two Majorana phases of the neutrino mixing matrix remain determined in terms of the set of already measured low energy observables, modulo a discrete ambiguity in the signs of two neutrino mixing angles and of the Dirac phase. The RH neutrinos mass spectrum is also predicted, as well as the size and sign of the leptogenesis CP asymmetries. We compute the cosmological baryon asymmetry generated through leptogenesis and obtain the correct sign and a size compatible with observations.

description: The relativistic Boltzmann equation for a single particle species generally implies a fixed, unchangeable equation of state that corresponds to that of an ideal gas. Real-world systems typically have more complicated equation of state which cannot be described by the Boltzmann equation. The present work derives a 'Boltzmann-like' equation that gives rise to a conserved energy-momentum tensor with an arbitrary (but thermodynamically consistent) equation of state. Using this, a Lattice Boltzmann scheme for diagonal metric tensors and arbitrary equations of state is constructed. The scheme is verified for QCD in the Milne metric by comparing to viscous fluid dynamics.

Usefulness of an equal-probability assumption for out-of-equilibrium states: a master equation approach

description: We examine the effectiveness of assuming an equal probability for states far from equilibrium. For this aim, we propose a method to construct a master equation for extensive variables describing non-stationary nonequilibrium dynamics. The key point of the method is the assumption that transient states are equivalent to the equilibrium state that has the same extensive variables, i.e., an equal probability holds for microscopic states in nonequilibrium. We demonstrate an application of this method to the critical relaxation of the two-dimensional Potts model by Monte Carlo simulations. While the one-variable description, which is adequate for equilibrium, yields relaxation dynamics that are very fast, redundant two-variable description well reproduces the true dynamics quantitatively. These results suggest that some class of the nonequilibrium state can be described with a small extension of degrees of freedom, which may lead to an alternative way to understand nonequilibrium phenomena.

title: Biophilic Tactical Urbanism: Experiments Between Temporary Architecture And Multispecies Design
Creators: name: Barnes, James
Publisher: name: Georgia Institute of Technology
Year: 2025

description: Tactical urbanism, the activation of public space through temporary interventions, has emerged as a common design strategy to promote longer-term positive shifts in the planning and formation of public spaces. The practice is typically positioned toward improving the human condition. This paper investigates how tactical urbanism might be expanded to a multispecies, “more-than-human” lens. How might tactical urbanism intersect with biodiversity in novel, scalable, and measurable ways to promote more sustainable, multispecies futures in the built environment? The term biophilic tactical urbanism is proposed as a design strategy and explored through 1:1 scale investigations and research experiments using a design science framework. This culminated in the development of a tactical urbanism system for plant ecologies: a low-cost, mobile, modular planter system for rapid deployment of biodiversity into new contexts. Five different design geometry/plant ecology concepts were developed, representing a range of biodiversity and programmatic opportunities. The intervention was deployed in the context of a public elementary school parking lot in the Mid-Atlantic US. This paper describes the results of this work on surrounding ecological systems, including invertebrates like bees and butterflies, as a metric of multispecies impact. Additionally, the intervention’s effect on urban heat were examined. Results indicate that temporary ecology can have a significant effect on the broader nature of public spaces, even at small spatial and temporal scales.

description: In this article we introduce a method to construct $\rm{G}_2$-instantons on $\rm{G}_2$-manifolds arising from Joyce's generalised Kummer construction. The method is based on gluing ASD instantons over ALE spaces to flat bundles on $\rm{G}_2$-orbifolds of the form $T^7/ Γ$. We use this construction to produce non-trivial examples of $\rm{G}_2$-instantons.

description: We calculate the static potential, the drag force and the jet quenching parameter in strongly coupled anisotropic N=4 super Yang-Mills plasma. We find that the jet quenching is in general enhanced in presence of anisotropy compared to the isotropic case and that its value depends strongly on the direction of the moving quark and the direction along which the momentum broadening occurs. The jet quenching is strongly enhanced for a quark moving along the anisotropic direction and momentum broadening happens along the transverse one. The parameter gets lower for a quark moving along the transverse direction and the momentum broadening considered along the anisotropic one. Finally, a weaker enhancement is observed when the quark moves in the transverse plane and the broadening occurs on the same plane. The drag force for quark motion parallel to the anisotropy is always enhanced. For motion in the transverse space the drag force is enhanced compared to the isotropic case only for quarks having velocity above a critical value. Below this critical value the force is decreased. Moreover, the drag force along the anisotropic direction is always stronger than the force in the transverse space. The diffusion time follows exactly the inverse relations of the drag forces. The static potential is decreased and stronger decrease observed for quark-antiquark pair aligned along the anisotropic direction than the transverse one. We finally comment on our results and elaborate on their similarities and differences with the weakly coupled plasmas.

Four-jet final state in same-sign lepton colliders and neutrinoless double beta decay mechanisms

description: If neutrinoless double beta decay is observed, it will be important to understand the mechanism(s) behind this process. Using a minimal supersymmetric extension to the Standard Model in association with a lepton number violating coupling as an example, we show that if neutrinoless double beta decay is mediated by new TeV scale particles, looking for four-jet final states in future linear colliders operating in the same-sign electron mode could provide important information on the underlying mechanisms. We study the prospects for observing this process at the proposed ILC and CLIC energies, and discuss the complementarity between such a four-jet signal and other collider signatures at the LHC.

description: Title: Liquid Time: A New Perspective on Temporal Dynamics and Consciousness

Authors: Luca Patrone & ChatGPT

Abstract:This paper explores the concept of Liquid Time, proposing that time is not a rigid, linear sequence but a fluid, adaptive system influenced by coherence, intention, and the observer’s cognitive state. Integrating insights from quantum physics, information theory, and consciousness studies, we examine how:

The perception of time shifts based on awareness and focus.

The past is dynamically reconstructed rather than fixed.

The future emerges probabilistically based on coherence.

By challenging traditional models of time, we suggest that self-organizing systems navigate temporal dynamics, allowing for more advanced scientific, cognitive, and technological applications.

title: DEPRECATED: INDUCTIVE REASONING IN PERSECUTORY DELUSIONAL THOUGHT
Creators: name: BAKER, IAN WALTER SHELLEY
Publisher: name: University of Plymouth
Year: 1997

description: Delusions are considered to be one of the primary symptoms of psychosis but until recently have received little empirical investigation. One approach has been to examine the extent to which deluded individuals demonstrate cognitive biases which are different from those of normal controls in inductive reasoning tasks. In this study two hypothesis testing tasks were used to investigate cognitive biases in a group of people with persecutory delusions compared to a group whose delusions had remitted and a normal control group. Participants completed two tasks consisting of a series of visual discrimination problems in which they had to choose between pairs of stimuli presented on cards. Condition 1 examined previously reported biases of deluded participants requiring less information before making judgements and being overconfident in their judgements. Positive or negative feedback was given after every card and participants were unconstrained in giving solutions. Condition 2 partially replicated Young and Bentall's (1995) hypothesis testing study and examined participants' ability to process information sequentially and progressively focus down the set of possible correct solutions. Feedback was restricted and participant responding was constrained. No differences were found between groups in condition 1. In condition 2 deluded participants produced fewer hypothesis and sampled from a smaller range of hypotheses than remitted and control participants. Deluded participants also produced fewer correct hypotheses than the other groups. A trend was found for deluded participants to use fewest sensible responses to feedback, followed by remitted and control groups. The reverse trend was found for use of nonsensical responses to feedback. Limitations of the study, implications for clinical practice and suggestions for future research are considered.

description: We present a generalization of the spinor and twistor geometry for on (pseudo) Riemannian manifolds enabled with nonholonomic distributions or for Finsler-Cartan spaces modelled on tangent Lorentz bundles. Nonholonomic (Finsler) twistors are defined as solutions of generalized twistor equations determined by spin connections and frames adapted to nonlinear connection structures. We show that the constructions for local twistors can be globalized using nonholonomic deformations with "auxiliary" metric compatible connections completely determined by the metric structure and/or the Finsler fundamental function. We explain how to perform such an approach in the Einstein gravity theory formulated in Finsler like variables with conventional nonholonomic 2+2 splitting.

description: We construct some irreducible representations of the Leavitt path algebra of an arbitrary quiver. The constructed representations are associated to certain algebraic branching systems. For a row-finite quiver, we classify algebraic branching systems, to which irreducible representations of the Leavitt path algebra are associated. For a certain quiver, we obtain a faithful completely reducible representation of the Leavitt path algebra. The twisted representations of the constructed ones under the scaling action are studied.
