description: We derive the formula of the entanglement entropy between the left and right oscillating modes of the $σ$-model with the de Sitter target space. To this end, we study the theory in the \emph{cosmological gauge} in which the non-vanishing components of the metric on the two-dimensional base space are functions of the expansion parameter of the de Sitter space. The model is embedded in the causal north pole diamond of the Penrose diagram. We argue that the cosmological gauge is natural to the $σ$-model as it is compatible with the canonical quantization relations. In this gauge, we obtain a new general solution to the equations of motion in terms of time-independent oscillating modes. The constraint structure is adequate for quantization in the Gupta-Bleuler formalism. We construct the space of states as a one-parameter family of Hilbert spaces and give the Bargmann-Fock and Jordan-Schwinger representations of it. Also, we give a simple description of the physical subspace as an infinite product of $\mathcal{D}^{+}_{\frac{1}{2}}$ in the positive discreet series irreducible representations of the $SU(1,1)$ group. We construct the map generated by the Hamiltonian between states at two different values of time and show how it produces the entanglement of left and right excitations. Next, we derive the formula of the entanglement entropy of the reduced density matrix for the ground state acted upon by the Hamiltonian map. Finally, we determine the asymptotic form of the entanglement entropy of a single mode bi-oscillator in the limit of large values of time.

description: There is increasing evidence that the highly ionized multiphase components of AGN disk winds may be due to thermal instability. The ions responsible for forming the observed X-ray absorption lines may only exist in relatively cold clumps that can be identified with the so-called 'warm absorbers'. Here we calculate synthetic absorption lines for such warm absorbers from first principles by combining 2D hydrodynamic solutions of a two-phase medium with a dense grid of photoionization models to determine the detailed ionization structure of the gas. Our calculations reveal that cloud disruption, which leads to a highly complicated velocity field (i.e. a clumpy flow), will only mildly affect line shapes and strengths when the cold gas becomes highly mixed but not depleted. Prior to complete disruption, clouds which are optically thin to the driving UV resonance lines will cause absorption at an increasingly blueshifted line of sight velocity as they are accelerated. This behavior will imprint an identifiable signature on the line profile if warm absorbers are enshrouded in an even broader absorption line produced by a high column of intercloud gas. Interestingly, we show that it is possible to develop a spectral diagnostic for cloud acceleration by differencing the absorption components of a doublet line, a result which can be qualitatively understood using a simple partial covering model. Our calculations also permit us to comment on the spectral differences between cloud disruption and ionization changes driven by flux variability. Notably, cloud disruption offers another possibility for explaining absorption line variability.

REACH Story of Change: Making water safe for maternal and neonatal care in Bangladesh
Creators: name: REACH
Publisher: name: University of Oxford
Year: 2023

description: Currently 77% of Bangladesh healthcare facilities have improved on-premises water supply, but there is no systematic data on the quality of the water for drinking or providing care. In partnership with UNICEF Bangladesh, the REACH programme undertook a pilot study to examine water quality in 14 rural public hospitals across eight districts, for both drinking and use in care giving.
The study demonstrates that water quality in hospitals is compromised by poorly maintained water systems in hospitals, as well as poor environmental hygiene, placing patients at risk of hospital acquired infections. It finds that water quality deteriorates from the source to the point of use, highlighting the need for proactive water safety plans for healthcare facilities, to deliver on infection prevention goals.
The collaborative research is expanding water safety planning approaches for hospitals in Bangladesh, creating transformative change at the facility level and informing care policy at the national level.
title: Cuba: representations of a quest for a hybrid identity
Creators: name: Perera, Jennifer Ballantine
Publisher: name: University of Kent

description: The debate surrounding Latin America within the postcolonial field is a continuing one informed by polarised views and the resistance in some Latin American academic quarters to a theory that is not historically relevant or sensitive to the differences between the colonial experiences in Latin America and those of India and Africa. My dissertation locates representations of Cuban cultural identity within a framework that views postcolonialism as part of an ongoing process of disengagements from colonialism and neo-colonialism. In a process that is constantly developing, fluidity and the opportunity to move away from fixed or polarised sites is created. This dissertation interrogates Cuban writings and artefacts, the strategies and manoeuvres adopted by intellectuals and writers around issues of race and cultural and racial hybridity within this postcolonial context. Using postcolonial concepts of hybridity, such as Homi Bhabha’s and Salman Rushdie’s as points of departure, I question these postcolonial theories within the Cuban context and alongside Cuban constructs of el mestizaje and syncretic theories of cultural and racial hybridity, as well as ideological constructs of cultural identity, to analyze their relevance to representations of Cuban cultural identity. I discuss a number of writers and artists through a variety of genre and media, and across emblematic events during the twentieth and opening years of the twenty-first century. In the first cluster of texts I investigate, I discuss Cuban concepts of racial and cultural hybridity though Fernando Ortiz’s Cuban Counterpoint: Tobacco and Sugar (1940), Nicolás Guillén’s performance before the Sociedad Femenina Lyceum (1932) and Alejo Carpentier’s ¡Ecue-Yamba-O! ([1927] 1933). The next cluster of texts, art works are bridged by two films, Tomás Gutiérrez Alea’s Memorias del subdesarollo (1968) and Mikhail Kalatozov’s Soy Cuba/Ja Kuba( 1964). These are followed by Ana Menéndez’s In Cuba I Was a German Shepherd (2001), Pedro Juan Gutiérrez’s Trilogía sucia de La Habana (1999) and the ceramics of the Cuban artist Roberto Loreto Marin Rodriguez (2002). I examine the content and complexity of these linkages as a totality to see how connections work together. I examine the binaries of coloniser/colonised which underlie so much postcolonial theory against the presence, in the Cuban examples I interrogate, of multiple internal and external forces that impact on representations of cultural identity. In doing so I suggest how the Cuban example expands or complicates postcolonial concepts of hybridity and engage with the relevance of postcolonial studies to Cuba.

description: We perform the Hamiltonian analysis of an on-shell U(1) gauge field theory, in which the action is not invariant under local U(1) transformations but recovers the invariance when the equations of motion are imposed. We firstly apply Dirac's method of Hamiltonian analysis. We find one first-class constraint and two second-class constraints in the vector sector. It implies the photons have only two polarisations, at least at the classical level, although the standard U(1) symmetry is explicitly broken. The reduced Hamiltonian is bounded from below and the on-shell U(1) gauge field theory is free from ghosts at the classical level.

description: Set up as a visual investigation, the research explores how the addition of paint and graphite materials onto the surface of found and discarded photographs, creates a visual and conceptual disjuncture by punctuating and altering the temporal frame of the photograph. The research is positioned in relation to Susan Sontag’s description in On Photography (1977) as to how the photograph can at once “transfix” and “anesthetize” the subject matter, which through the passage of time serves to create an “aesthetic distance,” and Roland Barthes’ observation in Camera Lucida (1980) that the photograph is “platitudinous.” The tendency to project nostalgic sentiment onto the found vernacular photograph is explored, drawing on Susan Stewart’s notion of the authentic object in On Longing (1984), which, it is argued, when expressed in the form of the found photographic object, becomes an emblem of loss, further exaggerating the sense of distance and impenetrability. Working specifically with the found photograph prompts a questioning of previous critical commentaries concerning painting over photographs, as in Gerhard Richter’s ‘Overpaintings,’ where Joannes Meinhardt (2009) suggests that the addition of paint intensifies the essential “speechlessness” of the photograph. This research extends these discourses and contributes a counter critical position, supported and articulated through an original body of work. It proposes that the applied paint on the surface of the found photograph punctures the essential “speechlessness” and unknowability magnified within this subset of photography. The very physical materiality and difference offered by the paint medium ruptures the perception of distance and mediates the tendency towards nostalgic interpretations, bringing a level of stability and certainty in the face of the uncertain, fluctuating meaning and temporal plane of the found photograph.
Changes in neuroinflammation, body temperature, and neuropeptide Y expression following exposure to calorie restriction in mice

Calorie restriction (CR) increases longevity and elicits many health-enhancing benefits. Although the underlying mechanisms of these effects are unknown, a likely contributor is altered immunity. We recently demonstrated that CR suppresses lipopolysaccharide (LPS)-induced fever and promotes an anti-inflammatory signalling bias in the hypothalamus. The current thesis extended this work by investigating regional changes in LPS-induced microglial activation in mice exposed to 50 percent CR or ad libitum feeding for 28 days. A set of brain sections were immunolabelled for ionized calcium-binding adapter molecule-1 (Iba1), a marker of microglial activation. We found that CR suppressed LPS-induced fever and microglial activation in the arcuate nucleus (ARC) and ventromedial nucleus of the hypothalamus and the subfornical organ. The ARC contains neurons that synthesise neuropeptide Y (NPY), an anti-inflammatory neuropeptide that is upregulated following CR. To investigate whether NPY expression in the ARC was associated with microglial activation, a set of hypothalamic sections were immunolabelled for NPY and the density was assessed in the ARC and the hypothalamic paraventricular nucleus (PVN). We also investigated microglial morphology by digitally constructing Iba1-positive cells in the ARC. We demonstrated that CR enhanced NPY-immunoreactivity in the ARC but not the PVN. CR also blunted the LPS-induced increase in Iba1 intensity and reduced microglia cell area in the ARC of LPS-treated mice. We found that the relationship between NPY and mean Iba1 intensity was statistically mediated by body temperature. Body temperature was also found to be strongly associated with both NPY and microglial cell area. Together, these data suggest that changes in NPY may be involved in the blunting of LPS-induced microglial activation following CR, specifically through its effects on LPS-induced fever.

description: In software engineering, techniques of continuous integration allow short test cycles and thus fast feedback cycles. However, if there is a need to change the deployment or update the functionality, it becomes difficult to assess the impact of such changes on performance. In this context, we present in this paper an extensible approach for reverse engineering of component-based systems for quality prediction. We build on the principles and techniques of model-driven engineering to analyze a system at the model level and to enable subsequent optimization.

description: Detection of non-technical losses (NTL) which include electricity theft, faulty meters or billing errors has attracted increasing attention from researchers in electrical engineering and computer science. NTLs cause significant harm to the economy, as in some countries they may range up to 40% of the total electricity distributed. The predominant research direction is employing artificial intelligence to predict whether a customer causes NTL. This paper first provides an overview of how NTLs are defined and their impact on economies, which include loss of revenue and profit of electricity providers and decrease of the stability and reliability of electrical power grids. It then surveys the state-of-the-art research efforts in a up-to-date and comprehensive review of algorithms, features and data sets used. It finally identifies the key scientific and engineering challenges in NTL detection and suggests how they could be addressed in the future.
title: Through the Filter of Ageing: Elsa Triolet, Mariama Bà and Maryse Condé
Creators: name: Barnes, Linda
Publisher: name: University of Kent
Year: 2022

description: This thesis explores the portrayal of literary images of ageing women through selected works by Mariama Bâ. Maryse Condé and Elsa Triolet. It looks at different generations, nationalities, races and cultures, yet, through the common medium of French, whilst their approaches may differ, all three writers ultimately display a perhaps surprising consensus with regard to the various travails that beset women d’un certain âge. In particular, and reading through the concept of liminality, I demonstrate that these authors uphold the view that, consciously or sub-consciously, women in their midlife years do undergo a rite of passage, with the changes in a woman’s body being mirrored by changes in her identity: life is, at least for these authors’ female characters, different after the menopause. Reading these novels through the filter of ageing, I explore how Elsa Triolet uses her characters to articulate, on a micro-level, her own fear and distress at the signs of deterioration of the physical body, whilst on a macro-level, and writing through a particularly turbulent period of history, her personal angst becomes a fear for the future of mankind. In contrast, both Mariama Bâ and Maryse Condé focus on the reconstruction of identity that is forced upon their characters as a result of their midlife crises, with lire resultant freedom from domination being expressed on various levels by both authors through their discourses on culture and identity. At the start of the twenty-first century, with growing awareness of our increased longevity and all its consequences, ageing is a topical subject. Given that youth and beauty are seen as tire holy grails of modem society, ageing women can easily feel marginalised, yet I argue that these authors demonstrate how one can take on the challenge of building a new relationship with one’s changing body and successfully negotiate the passage of time.

description: Consider an exact category in the sense of Quillen. Assume that in this category every morphism has a kernel and that every kernel is an inflation. In their seminal 1982 paper, Beilinson, Bernstein and Deligne consider in this setting a t-structure on the derived category and remark that its heart can be described as a category of formal quotients. They further point out that the category of Banach spaces is an example, and that here a similar category of formal quotients was studied by Waelbroeck already in 1962. In the current article, we give a direct and rigorous construction of the latter category by considering first the monomorphism category. Then we localize with respect to a multiplicative system. Our approach gives rise to a heart-like category not only for the Banach spaces. In particular, the main results apply to categories in which the set of all kernel-cokernel pairs does not form an exact structure. Such categories arise frequently in functional analysis.

description: In 2016, a results-based funding model was developed to improve the reliability of rural drinking water supply services in Kenya. The Water Services Maintenance Trust Fund (WSMTF) has tested a professional service delivery model in two counties and attracted new sources of results-based funds to guarantee water services in rural communities.
The WSMTF provides an example of how the funding gap can be met by non-donor funds in results-based contracts. In 2017, donor funds paid for 81% of WSMTF contracts, by 2021, the donor proportion had fallen to 14%. In the same period, the annual WSMTF resources increased from just under USD 50,000 to over USD 150,000.
The WSMTF has informed the work of the Uptime Catalyst Facility which has issued results-based contracts guaranteeing reliable drinking water for over 4 million rural people in 12 countries in 2023.
Ownership structure, related-party transactions and firm valuation: evidence from Indian business groups

description: Submission note: A thesis submitted in total fulfilment of the requirements for the degree of Doctor of Philosophy to the Department of Accounting, Business School, Faculty of Business, Economics and Law, La Trobe University, Bundoora.

The aim of this study is to examine the effect of ownership structure and disclosure of related-party (RP) transactions on firm valuation of group-affiliated firms in India, by using a sample of 317 listed firms comprising 1350 firm-year observations for the period 2008-2012. In particular, the value-relevance models examine the effect of ownership rights on market value of equity (MVE) and valuation effect of RP trading, asset transfer, investment and loan transactions. The empirical results reveal a positive and linear association between direct ownership rights and firm value, whereas there is strong evidence supporting a curvilinear association between indirect ownership rights of controlling shareholders and firm value, suggesting the use of cross-holding and pyramid structures for extracting private benefits. Furthermore, the indirect ownership rights of controlling shareholders possess important explanatory power of RP transactions valuation. RP trading and asset transfer transactions involving group-member firms negatively affect firm value in the presence of indirect ownership rights of controlling shareholders, whereas similar transactions involving subsidiary and holding firms are benign for market valuation. Firms engaged in RP investment and loan transactions with subsidiary and holding firms have significantly lower market valuation. However, indirect ownership rights of controlling shareholders do not influence the earnings-market valuation of these transactions. These findings are robust after controlling for firm-specific attributes, corporate governance and additional sensitivity tests. This is the only study to my knowledge that examines market valuation of RP transactions in the context of India. It contributes to the extant literature by recording distinct valuation of RP transactions involving group-member firms from similar transactions involving subsidiary/holding firms and providing evidence on the role of pyramid structures in understanding the valuation of RP transactions. The findings provide evidence that RP transactions between group-member firms are valued differently from RP transactions involving subsidiary and holding firms. The tunneling incentives of controlling shareholders, measured by indirect ownership rights, influence the valuation of RP transactions relating group-member firms, whereas the nature of transactions affects the valuation of RP transactions between subsidiary and holding firms.

description: The burden of alcohol-related complications is high and rising. However, there are notable deficiencies in comprehensive epidemiological study focusing on cardiovascular complications from alcohol, especially among young and middle-aged adults. We thus aimed to determine the burden of these conditions in young and middle-aged adults globally. We used data from the Global Burden of Disease Study 2019 and analysed the mortality and disability-adjusted life years of alcohol-associated cardiovascular complications in young and middle-aged adults. The findings were classified by sex, region, country, and Sociodemographic Index (SDI). The highest age-standardized death rates (ASDR) were observed in stroke 0.84 (95% UI 0.60–1.09), followed by alcoholic cardiomyopathy 0.57 (95% UI 0.47–0.66) per 100,000 population. The overall burden of alcohol-associated cardiovascular complications decreased globally but increased in atrial fibrillation and hypertensive heart disease. Regionally, most regions underwent a decrease in ASDR, but an increase was observed in Southeast Asia (+2.82%), Western Pacific (+1.48%), low-middle (+1.81%), and middle SDI (+0.75%) countries. Nevertheless, the ASDR and ASDALYs were highest in Europe. The impact of alcohol-associated atrial fibrillation and hypertensive heart disease has increased over the last decades. Regarding region, the burden in Europe and the rising burden in Asia, require immediate public health policy to lessen these cardiovascular complications from alcohol in young and middle-aged adults.

description: The discovery of orbital angular momentum (OAM) in light established a new degree of freedom by which to control not only its flow but also its interaction with matter. Here, we show that by shaping extremely sub-wavelength polariton modes, for example by imbuing plasmon and phonon polariton with OAM, we engineer which transitions are allowed or forbidden in electronic systems such as atoms, molecules, and artificial atoms. Crucial to the feasibility of these engineered selection rules is the access to conventionally forbidden transitions afforded by sub-wavelength polaritons. We also find that the position of the absorbing atom provides a surprisingly rich parameter for controlling which absorption processes dominate over others. Additional tunability can be achieved by altering the polaritonic properties of the substrate, for example by tuning the carrier density in graphene, potentially enabling electronic control over selection rules. Our findings are best suited to OAM-carrying polaritonic modes that can be created in graphene, monolayer conductors, thin metallic films, and thin films of polar dielectrics such as boron nitride. By building on these findings we foresee the complete engineering of spectroscopic selection rules through the many degrees of freedom in the shape of optical fields.

description: Merged with duplicate record 10026.1/850 on 10.04.2017 by CS (TIS)
description: This thesis evaluates the utility of a geochemical technique for the investigation of palaeoenvironmental change in south west England. The method, EDMA (Energy Dispersive X-ray Micro Analysis), is a rapid, non-destructive analysis tool, capable of detecting a large range of geochemical elements. This research examines the most appropriate method of sample preparation for organic soils and peats, and investigates the reliability of results gained from EDMA with respect to conventional bulk geochemical techniques. A detailed study focused on a range of different sedimentary sites in south west England where a variety of palaeoenvironmental changes were thought to occur. Pollen analysis was undertaken on the same sedimentary material, and provided complementary information on the nature and scale of vegetation change through time. Sediments from a coastal valley mire near North Sands, Salcombe, revealed information relating to the processes of sea-level change in this part of south Devon and the subsequent autogenic processes as the sediment accumulated through time. A range of sites were located on the granitic upland of Dartmoor. A raised bog, Tor Royal, provided data relating to the changing nature of the central upland landscape from late Mesolithic times to the present day. Two soligenous sites. Upper Merrivale and Piles Copse, sought to investigate the activities of postulated anthropogenic activity at a much smaller spatial scale, with particular interest placed upon the evidence for deforestation activity and the utilisation of the local mineral resources. The last site, Crift Down, a lowland spring fed valley mire utilised geochemical and palynological fluxes within the peat to investigate processes and activities associated with archaeological evidence for Medieval tinworking in this area of Cornwall. The results from the EDMA investigations, and comparable studies using other geochemical methods including EMMA, AAS and flame photometry, suggest the technique to have greatest applicability as a first stage tool in the analysis of general activities of past environmental change. The technique was found to yield reliable results for the major elements (Si, Al, S, Fe, Ca, K, Na and Mg), but is generally incapable of providing useful data on heavy metal elements. The data from south west England suggest the method to reflect activity at a range of different scales, and as part of a structured programme of analysis may contribute information to allow a more holistic environmental reconstruction to be made.

Apoptosis is a process used to remove cells that are old, damaged and potentially dangerous. Infection of a host cell by a virus can trigger apoptosis, limiting virus production and spread. Many viruses have evolved strategies to delay or inhibit apoptosis by expressing proteins that target conserved members of the apoptotic pathway. The genome of a member of the baculovirus family was sequenced and it was proposed to encode a novel anti-apoptotic protein (choc15). Choc15 shows sequence homology to members of the P35 and P49 inhibitor families that have been shown previously to inhibit a range of caspases. This study tested the activity, specificity and quantitated inhibition of caspase activity by choc15 against a range of mammalian and insect caspases. BmP35 from Bombyx mori Nucleopolyhedrovirus previously showed an ability to inhibit caspase 3 activity in cell culture and cell free systems. BmP35 showed strong sequence homology to AcP35 but appears to have weaker inhibitory activity against caspases. This study also tested the activity, specificity and quantitated the inhibition by BmP35 against a range of caspases.

description: Diabetes is a chronic disease affecting millions worldwide, leading to severe complications if notdetected early. Early prediction enables timely medical intervention and lifestyle changes, reducing healthrisks. Machine learning (ML) techniques have proven effective in predicting diabetes using clinical andlifestyle-related data. Among them, the Light Gradient Boosting Machine (LightGBM) is highly efficient inhandling large datasets, offering faster training speed and improved accuracy. Compared to traditionalmodels like logistic regression and decision trees, LightGBM excels in feature selection, reduces overfitting,and enhances predictive performance. This survey explores various ML techniques for early diabetesprediction, focusing on LightGBM’s advantages. The integration of ML in healthcare can improve earlydiagnosis, optimize treatment plans, and enhance patient outcomes, making LightGBM a valuable tool indiabetes management.

A class of sub-grid models is considered which represent non-local behavior via a finite memory approximation (Stinis, P., "Mori-Zwanzig reduced models for uncertainty quantification I: Parametric uncertainty," \textit{arXiv:1211.4285}, 2012.), the length of which is determined using a heuristic that is related to the spectral radius of the Jacobian of the resolved variables. The resulting models are intimately tied to the underlying numerical resolution and are capable of approximating non-Markovian effects. Numerical experiments on the Burgers equation demonstrate that the M-Z-based models can accurately predict the temporal evolution of the total kinetic energy and the total dissipation rate at varying mesh resolutions. The trajectory of each resolved mode in phase-space is accurately predicted for cases where the coarse-graining is moderate. LES of homogeneous isotropic turbulence and the Taylor Green Vortex show that the M-Z-based models are able to provide excellent predictions, accurately capturing the sub-grid contribution to energy transfer. Lastly, LES of fully developed channel flow demonstrate the applicability of M-Z-based models to non-decaying problems. It is notable that the form of the closure is not imposed by the modeler, but is rather derived from the mathematics of the coarse-graining, highlighting the potential of M-Z-based techniques to define LES closures.

description: Recently in (Eur. Phys. J. C 76:341, 2016) [arXiv:1604.08706], Myung has suggested that the renormalizability of massive conformal gravity is meaningless unless the massive ghost states of the theory are stable. Here we show that massive conformal gravity can be renormalizable having unstable ghost states.

description: We propose and analyze two distinct routes toward realizing interacting symmetry-protected topological (SPT) phases via periodic driving. First, we demonstrate that a driven transverse-field Ising model can be used to engineer complex interactions which enable the emulation of an equilibrium SPT phase. This phase remains stable only within a parametric time scale controlled by the driving frequency, beyond which its topological features break down. To overcome this issue, we consider an alternate route based upon realizing an intrinsically Floquet SPT phase that does not have any equilibrium analog. In both cases, we show that disorder, leading to many-body localization, prevents runaway heating and enables the observation of coherent quantum dynamics at high energy densities. Furthermore, we clarify the distinction between the equilibrium and Floquet SPT phases by identifying a unique micromotion-based entanglement spectrum signature of the latter. Finally, we propose a unifying implementation in a one-dimensional chain of Rydberg-dressed atoms and show that protected edge modes are observable on realistic experimental time scales.

description: In designing for longer product lifetimes we should consider our relationships not only with “products” but with “things” and “stuff”. The role of materiality in longer relationships with everyday artefacts may not have attracted as much attention as other factors, despite environmental relevance. This paper investigates awareness of stuff in the sense of unimportant everyday artefacts and also stuff in the sense of the material make-up of these artefacts. We highlight findings related to material awareness as a component of longer everyday product relationships. The findings around the role of the materiality in longer product relations reveal an ambiguous picture. Firstly the awareness of the material aspects of the everyday products commented on is very unevenly distributed. Comments related to material qualities of objects as well as the material presence of objects as physical entities are missing from many personal narratives collected. At the same time, an awareness of material, in the sense of the actual physical presence and nature of an object appears important in many of the longer everyday relationships commented. Relations to materiality in the research can thus be grouped into two distinct sections, firstly how materiality is present and appears to positively contribute to longer product relations, and secondly how materiality may go unnoticed in relationships with everyday objects. Being conscious of stuff as material may not constitute the majority of current behaviour (and may not be easy to encourage) but may be increasingly important in the context of product longevity.

description: Dynamical phase transitions (DPTs) in the space of trajectories are one of the most intriguing phenomena of nonequilibrium physics, but their nature in realistic high-dimensional systems remains puzzling. Here we observe for the first time a DPT in the current vector statistics of an archetypal two-dimensional (2d) driven diffusive system, and characterize its properties using macroscopic fluctuation theory. The complex interplay among the external field, anisotropy and vector currents in 2d leads to a rich phase diagram, with different symmetry-broken fluctuation phases separated by lines of first- and second-order DPTs. Remarkably, different types of 1d order in the form of jammed density waves emerge to hinder transport for low-current fluctuations, revealing a connection between rare events and self-organized structures which enhance their probability.

description: Submission note: A thesis submitted in total fulfilment of the requirement for the degree of Doctor of Philosophy to the School of Human Biosciences, Faculty of Health Sciences, La Trobe University, Bundoora.

In the past, forensic handwriting examination has received scrutiny about a paucity of empirical evidence supporting claims and theories within the field. This dissertation uses a novel framework that combines objective eye-tracking and hand kinematics with forensic document examiner opinions and simulators’ perceptions to gain further insight into the cognitive and behavioural processes involved in signature simulation. Experiment one focuses on the perceptions of simulators and uses an advanced statistical model to answer questions relating to signature simulation difficulty, signature complexity and signature legibility. Further experimentation builds on the findings by investigating the gaze strategies of simulators, the quality of signature simulations and the behavioural relationship between eye and hand movements during signature simulation. Collectively, the findings of this dissertation provide valuable novel insights into the signature simulation process, whilst validating some of the theoretical concepts related to the field of handwriting examination and human behaviour.

description: Effective treatment of non-ST-segment elevation acute coronary syndromes (NSTEACS) requires careful assessment of both ischaemic and bleeding risks. We aimed to analyse risk distribution and evaluate antiplatelet prescription behaviours in real-life settings. Data from 1100 NSTEACS patients in Buenos Aires, Argentina, from the Buenos Aires I Registry, with a 15-month follow-up, were analysed. In-hospital and 6-month GRACE scores, CRUSADE, and Precise DAPT scores were calculated. The mean age was 65.4 ± 11.5 years with a majority being male (77.2%). In-hospital mortality was 2.7%, primarily due to cardiovascular causes (1.8%). Bleeding events occurred in 20.9% of patients, with 4.9% classified as ≥ BARC 3. Predominance of low bleeding (71.3%) and ischaemic (55.8%) risks on admission was observed. At 6 months, the low-risk Precise category (70.9%) and GRACE (44.1%) categories prevailed. Linear correlation analysis showed a moderately positive correlation (r = 0.61, p < .05) between ischaemic–haemorrhagic risks. Regarding the prescription of antiplatelet agents, in the low ischaemic–haemorrhagic risk group, there was a predominance of aspirin + clopidogrel (41.2%) over other high-potency antiplatelet regimens (aspirin + ticagrelor or prasugrel). In the low ischaemic and high haemorrhagic risk group, aspirin and clopidogrel were also predominant (58%). Our analysis underscores the significant relationship between ischaemic and haemorrhagic risks during NSTEACS hospitalisation. Despite the majority of patients falling into the low-intermediate risk category, the prescription of P2Y12 inhibitors in real-life settings does not consistently align with these risks.
