description: Stereochemical determination of flexible, trinor-guaiane sesquiterpenoids, antheliol (1a) and sangiagol B (2a), isolated from a marine soft coral, Anthelia sp., was supported by quantum chemical calculations of NMR chemical shifts at DFT levels. The relative configuration of antheliol is now revealed, as 1S*, 4S*, 7S*, 10R* as in 1b, whereas sangiangol B (2c) has complete stereochemistry as 1S*, 7R*, 8R*, 10R*, 11R*, 12S*.

description: One of the central quantities of a lithium ion intercalation compound is the open circuit potential, the voltage a battery material delivers in thermodynamic equilibrium. This voltage is related to the chemical potential of lithium in the insertion material and in general a non-linear function of the mole fraction of intercalated lithium. Experimental data shows further that it is specific for various materials. The open circuit voltage is a central ingredient for mathematical models of whole battery cells, which are used to investigate and simulate the charge and discharge behavior and to interpret experimental data on non-equilibrium processes. However, since no overall predictive theoretical method presently exists for the open circuit voltage, it is commonly fitted to experimental data. Simple polynomial fitting approaches are widely used, but they lack any thermodynamic interpretation. More recently systematically and thermodynamically motivated approaches are used to model the open circuit potential. We provide here an explicit free energy density which accounts for variable occupation numbers of Li on the intercalation lattice as well as Redlich--Kister-type enthalpy contributions. The derived chemical potential is validated by experimental data of Liy(Ni1/3Mn1/3Co1/3)O2 and we show that only two parameters are sufficient to obtain an overall agreement of the non-linear open circuit potential within the experimental error.

description: Η μεταπτυχιακή εργασία με θέμα «Η Κοπτική Κοινότητα στην Ελλάδα: Το ζήτημα της θρησκευτικής ταυτότητας σε ένα νέο περιβάλλον» επιχειρεί να διερευνήσει τα ταυτοτικά χαρακτηριστικά της κοπτικής κοινότητας στην Ελλάδα. Πιο συγκεκριμένα, με βάση την επιτόπια έρευνα που πραγματοποιήθηκε στο θρησκευτικό και πολιτιστικό κέντρο των Κοπτών στην Ελλάδα, το οποίο εδρεύει στην Αθήνα (Αχαρνές) διερευνάται η εγκατάσταση και η θρησκευτικο-πολιτισμική οργάνωση των Κοπτών στην Ελλάδα, το κοινωνικό-οικονομικό και πολιτισμικό τους προφίλ, η θρησκευτικό-εκκλησιαστική τους ταυτότητα και η εν γένει πολιτισμική τους κουλτούρα, με τα ιδιαίτερα χαρακτηριστικά που την απαρτίζουν, καθώς και η σχέση τους τόσο με τη χώρα προέλευσης (Αίγυπτος) στην οποία κυριαρχεί η αραβοισλαμική κουλτούρα, όσο και η σχέση τους με τη χώρα υποδοχής (Ελλάδα) και την επικρατούσα ελληνο-ορθόδοξη κουλτούρα. Ιδιαίτερη έμφαση δίνεται στην αποτύπωση και αναπαραγωγή της λατρευτικής και εν γένει θρησκευτικής ζωής, όπως έχει διαμορφωθεί από την πλούσια κοπτική παράδοση, αλλά και τις αναγκαίες προσαρμογές στο ελληνικό περιβάλλον, ώστε αφενός να διατηρεί την αυθεντικότητά της, αφετέρου να έχει τη δυνατότητα να διαλέγεται με την περιβάλλουσα κοινωνία.
description: The current master's thesis "The Coptic Community in Greece: The question of religious identity in a new environment" attempts to investigate the identity characteristics of the Coptic community in Greece. Specifically, based on the methodology of field research carried out at the religious and cultural center of the Copts in Greece, which is based in Athens (Acharnes), the settlement and religious-cultural organization of the Copts in Greece, their socio-economic and cultural profile are investigated , their religious-ecclesiastical identity and their culture in general, with the particular characteristics that make it up, as well as their relationship both with the country of their origin (Egypt) in which the Arab-Islamic culture is the dominant one, and their relationship with the host country (Greece) and the prevailing Greek-Orthodox culture. Particular emphasis is placed on capturing and reproducing the devotional and in general religious life, as it has been shaped by the rich Coptic tradition, but also the necessary adaptations to the Greek environment, so that on the one hand it maintains its authenticity, on the other hand it has the possibility to co-exist and interact with the surrounding society.
title: Stereotype homosexueller Frauen
Creators: name: Bobrowsky, Natascha
Year: 2023

description: Während der wissenschaftlichen Konstruktion von Homosexualität am Ende des 19. und frühen 20. Jahrhunderts entstanden Stereotype (als Konstruktionen von Fremdbildern) des gleichgeschlechtlichen Begehrend und Handelns. Fragend, welche Stereotype homosexuel- ler Frauen in Diskursen der Medizin, Rechtswissenschaften und Politik seit den 1860er-Jah- ren im deutschsprachigen Raum konstruiert wurden, steht im Zentrum der vorliegenden For- schungsarbeit auch die Analyse deren (Dis-)Kontinuitäten bis in die Zeit des Nationalsozia- lismus. Dabei wird der Hypothese nachgegangen, wonach in diesen Diskursen vor allem zwei Stereotype über homosexuelle Frauen bestanden, die im Wesentlichen von den Sexu- alwissenschaften entwickelt wurden – und die Diskurse während des Nationalsozialismus maßgeblich prägten. Das rund 20 Quellen umfassende Sample wurde aus Publikationen zu- sammengesetzt, welche für den jeweiligen Untersuchungszeitraum als repräsentativ gelten können, und inkludiert unter anderem Arbeiten von Richard von Krafft-Ebing, Wenzeslaus von Gleispach oder auch Rudolf Lemke. Die Analyse der Quellen orientiert sich an einer qualitativen Inhaltsanalyse nach Philipp Mayring. Anhand der sich ergebenden Analyseta- bellen wird gezeigt, dass in sexualwissenschaftlichen Publikationen zwischen 1860 und 1920 insbesondere das Stereotyp der „echten“ und/oder maskulinen homosexuellen Frau konstruiert wurde sowie das Stereotyp der „pseudohomosexuellen“ Frau, diese jedoch in Diskursen im Kontext des Nationalsozialismus unterschiedlich rezipiert wurden.
description: During the scientific construction of homosexuality at the end of the 19th and early 20th century, stereotypes (as the construction of images of others) of homosexuality emerged. This thesis, examining the German-speaking region, focuses not only on questioning which stereotypes about homosexual women were constructed in discourses of medicine, jurispru- dence and politics since the 1860s, but also on questioning their (dis-)continuities up to the time of National Socialism. Therefor the testing of the hypothesis is pursued that since the emergence of the sexual sciences, two stereotypes about homosexual women in particular have existed and that these have significantly shaped the discourses under National Social- ism. The sample of about 20 sources was composed of publications that can be considered representative for the respective period and includes, among others, works by Richard von Krafft-Ebing, Wenzeslaus von Gleispach, and Rudolf Lemke. The analysis of the sources is inspired by a qualitative content analysis according to Philipp Mayring. Based on the result- ing analysis tables, it will be shown that in sexual scientific publications between 1860 and 1920, the stereotype of the "real" and/or masculine homosexual woman was constructed, as well as the stereotype of the "pseudohomosexual" woman, but were received differently in discourses in the context of National Socialism.

description: The aim of the present thesis is the study of pejorative suffixes in Modern Greek (MG). First, we provide a literature review of the etymology, form, and meaning of pejorative suffixes in MG. Then, we examine the bases and derivatives, concerning the types of lexical units, morphosyntactic, semantic and pragmatic features, as well as their availability and offensiveness, which are summarized in a Lexeme Formation Rule. In addition, digital corpora contribute to the study of suffixes. More specifically, the data come from the Corpus of Greek Texts (CGT), a large and representative collection of oral and written texts, encompassing a multitude of genres. Finally, we compare the pejorative suffixes of MG, in order to highlight their similarities, but also the subtle morphosyntactic, semantic and pragmatic differences, which account for the synchronic and diachronic co-existence of these suffixes in the language system.

description: Although microcystins (MCs) are the most commonly studied cyanotoxins, their significance to the producing organisms remains unclear. MCs are known as endotoxins, but they can be found in the surrounding environment due to cell lysis, designated as extracellular MCs. In the present study, the interactions between MC producing and the non-producing strains of Microcystis aeruginosa, PCC 7806 and PCC 7005, respectively, and a green alga, Desmodesmus subspicatus, were studied to better understand the probable ecological importance of MCs at the collapse phase of cyanobacterial blooms. We applied a dialysis co-cultivation system where M. aeruginosa was grown inside dialysis tubing for one month. Then, D. subspicatus was added to the culture system on the outside of the membrane. Consequently, the growth of D. subspicatus and MC contents were measured over a 14-day co-exposure period. The results showed that Microcystis negatively affected the green alga as the growth of D. subspicatus was significantly inhibited in co-cultivation with both the MC-producing and -deficient strains. However, the inhibitory effect of the MC-producing strain was greater and observed earlier compared to the MC-deficient strain. Thus, MCs might be considered as an assistant factor that, in combination with other secondary metabolites of Microcystis, reinforce the ability to outcompete co-existing species.

description: Today, the dairy industry is comprised of cows that can produce around 20,000 pounds of milk in a year, yet producers often see only 30% to 50% of animals produce a live calf after each breeding. While many factors may be at play, there is evidence that the immune system plays a large role in regulating pregnancy and in preventing immune mediated abortions. Maternal immune system changes during pregnancy have been shown to occur both locally in the uterus, which is in direct contact with the placenta, and systemically in the blood. Research in humans and mice has shown that the immune cell populations of CD4+CD25+ γ/δ TCR+ play substantial roles as T regulatory cells and they support the development of the conceptus through trophoblast cell growth. However, in cattle these cells have not been identified. We proposed a co-culture experiment to identify which T cell populations in the cow support placental growth.
We isolated and cultured the following T cell populations: CD4+, CD4+CD25+, CD4+CD25-, CD8+, and γ/δ TCR+ from pregnant and non-pregnant cows to obtain T cell conditioned medium and treat placental trophoblast cells. T cells secrete cytokines and growth factors that might alter trophoblast cell growth and development. We analyzed trophoblast cell proliferation, apoptosis, and gene expression to identify which T cell populations support placental development. Our results show that trophoblast cell gene expression is modulated by T cell supernatant obtained from pregnant cows differently than T cell supernatant from non-pregnant cows. These results will contribute to the development of strategies that could reduce rates of immune-mediated pregnancy loss. A cost-effective approach to reduce pregnancy loss in cattle could reduce monetary loss to farmers by allowing production animals to be more reproductively efficient and stay in the herd for longer.

description: In lakes, cyanobacterial blooms are frequently associated with green algae and dominate the phytoplankton community in successive waves. In the present study, the interactions between Microcystis aeruginosa PCC 7806 and Desmodesmus subspicatus were studied to clarify the probable ecological significance of algal secondary metabolites; focusing on the role of cyanotoxin ‘microcystin-LR’ (MC-LR). A dialysis co-cultivation technique was applied where M. aeruginosa was grown inside and D. subspicatus was cultured outside of the dialysis tubing. The concentration of the intra- and extracellular MC-LR and the growth of two species were measured at different time points over a period of one month. Additionally, the growth of the two species in the culture filtrate of one another and the effect of the purified MC-LR on the growth of the green alga were studied. The results indicated that the co-existing species could affect each other depending on the growth phases. Despite the early dominance of D. subspicatus during the logarithmic phase, M. aeruginosa suppressed the growth of the green alga at the stationary phase, which coincided with increased MC production and release. However, the inhibitory effects of Microcystis might be related to its other extracellular metabolites rather than, or possibly in addition to, MC.
Understanding the functionality of the transcription factor ERG at a molecular level
Creators: name: Stroobants, Astrid
Publisher: name: Imperial College London
Year: 2021

description: The ETS transcription factor ERG is a master regulator of multiple vascular processes. Pathological dysregulation of endothelial ERG has been linked to inflammatory disorders. In non-endothelial cells, aberrant ectopic overexpression of ERG in cancer is oncogenic. Whilst many aspects of ERG’s biological and pathological role have been uncovered, the underlying molecular mechanisms are often not fully understood; likely impeded by the lack of a full-length crystal structure. I combined in silico Molecular Dynamics (MD) and in vitro assays to gain further insight into the functionality of ERG at the molecular level. A new ERG full-length structure was developed using MD. This model was used to study the structural basis for the binding specificity of ERG at DNA sequence variants of the ERG binding site. This identified key changes in ERG-DNA contacts depending on the binding motif. ERG activity can be modulated through posttranslational modifications including phosphorylation. Using the new ERG structural model, I gained a better understanding of the molecular consequences of ERG phosphorylation by ERK2. I found that upon Ser215 and Ser96 phosphorylation ERG undergoes conformational changes in the C- and N- termini, respectively. Using an electrophoresis mobility shift assay I showed that Ser215 phosphorylation increased the DNA binding of ERG. This goes in line with the in silico observed structural change in the C-terminus of ERG, where the DNA binding domain is located. Finally, I identified structural differences in the DNA binding ETS domain in an ERG variant found in a patient with primary lymphodoema. I showed changes in DNA binding, which was confirmed independently using in vitr oassays. Overall, the new structural modelwas successfully used to gain insight into the molecular mechanism underlying ERGactivity. Other aspects of ERG activity could be studied with the new model, potentially aiding the development of new therapeutic strategies.
Take-over expectation and criticality in Level 3 automated driving: a test track study on take-over behavior in semi-trucks

description: With the introduction of advanced driving assistance systems managing longitudinal and lateral control, conditional automated driving is seemingly in near future of series vehicles. While take-over behavior in the passenger car context has been investigated intensively in recent years, publications on semi-trucks with professional drivers are sparse. The effects influencing expert drivers during take-overs in this context lack thorough investigation and are required to design systems that facilitate safe take-overs. While multiple findings seem to cohere in passenger cars and semi-trucks, these findings rely on simulated studies without taking environments as found in the real world into account. A test track study was conducted, simulating highway driving with 27 professional non-affiliated truck drivers. The participants drove an automated Level 3 semi-truck while a non-driving-related task was available. Multiple time critical take-over situations were initiated during the drives to investigate four main objectives regarding driver behavior. (1) With these results, comparison of reaction times and behavior can be drawn to previous simulator studies. The effect of situation criticality (2) and training (3) of take-over situations is investigated. (4) The influence of warning expectation on driver behavior is explored. Results obtained displayed very quick time to hands on steering and time to first reaction all under 2.4 s. Highly critical situations generate very quick reaction times M = 0.81 s, while the manipulation of expectancy yielded no significant variation in reaction times. These reaction times serve as a reference of what can be expected from drivers under optimal take-over conditions, with quick reactions at high speed in critical situations.

title: Venturi Flowmeter Performance Installed Downstream of the Branch of a Tee Junction
Creators: name: Sandberg, Benjamin G.
Publisher: name: Utah State University
Year: 2020

description: The purpose of this research was to evaluate the influence of a tee junction on flow rate measurement of a Venturi flowmeter installed downstream of the branch of a tee. Accuracy in flow measurement is important to organizations where miscalculated flow rates can add up to be millions of dollars in either lost revenue, overcharges to the client, or improper system operation. This research used Computational Fluid Dynamics (CFD) to determine ratios by which the manufacturer’s straight-line calibrated 𝐶𝑑 (discharge coefficient) can be adjusted to improve the accuracy of the flow measurement when the Venturi is installed on the branch of a tee. Physical laboratory data was obtained for a 6-in. Venturi in a straight-line, followed by installation on the branch of a tee at zero pipe diameters and five pipe diameters downstream. CFD modeling was then used.
Results show the flow rate measurement was less affected when all flow was entering the tee branch and more affected when less flow was entering the tee branch. While physical laboratory calibration is still the best way to get the most accurate flow measurement performance for a Venturi, using CFD to create contour plots of 𝐶𝑑 ratios to adjust manufacturer given 𝐶𝑑s over a range of Reynolds numbers and flow splits entering the tee could be an option.
Novel polymeric surfactants to stabilise emulsions

Publisher: name: Imperial College London
Year: 2021

description: This PhD project aims to synthesise polymeric surfactants, characterise their aqueous solution properties and emulsifying abilities, and obtain a structure-property relationship. In this study, different polymeric surfactants were synthesised using Group Transfer Polymerisation (GTP) method. The first project of this PhD thesis includes the synthesis of two series of diblock copolymers and the characterisation of their aqueous solution properties and emulsifying abilities. In order to make a comparison between the two-polymer series, the molar mass (MM), composition and hydrophobic monomer kept the same, whereas different hydrophilic monomer used for each polymer series. Thus, in both series, ethyl methacrylate (EtMA) was used as a hydrophobic monomer, and poly(ethylene glycol) methyl ether methacrylate (PEGMA) and 2-(dimethylamino) ethyl methacrylate (DMAEMA) was used as a hydrophilic monomer in Polymer series 1 and 2, respectively. The second project of this PhD thesis includes the synthesis of triblock copolymers using the same monomers studied in the previous project; PEGMA, EtMA and DMAEMA. The architecture of the linear triblock copolymers is ABC (A is PEGMA, B is EtMA, and C is DMAEMA), and it kept the same in the whole project. Moreover, the MM and composition of the copolymers kept the same as with the previous chapter to observe the effects of diblock and triblock copolymers on their properties. The third project of this PhD thesis includes the synthesis of seven different architecture of copolymers varying from statistical to gradient, diblock, triblock copolymers. The copolymers were based on hydrophilic DMAEMA and hydrophobic n-butyl methacrylate units. The MM and composition kept constant to observe the effect of architecture on the emulsifying and aqueous solution properties. It was found that the all the polymers were successfully synthesised and the effective pKa (if any), cloud points, critical micelle concentrations (CMC) and hydrophile-lipophile balance (HLB) values, and hydrodynamic diameters were affected by the structure of the polymers, such as composition and MM. Most importantly, all polymeric surfactants were found to emulsify methyl laurate in water, and the stability of the emulsions was found to strongly depend on the architecture, composition and MM of the polymers.
Maternal cardiovascular adaptation to pregnancy in women with previous bariatric surgery and obese pregnant women

description: The prevalence of obesity in pregnancy is rising every year both in the UK and globally. Obese pregnant women are often of childbearing age and go on to have high risk pregnancies with increased risk of hypertensive disorders, gestational diabetes and large-for-gestational age neonates. Bariatric Surgery is a highly successful treatment for sustained weight loss and its use in the management of obesity is growing. Studies of individuals before and after bariatric surgery, outside of pregnancy, have shown a reduction or resolution in hypertension, cardiac remodelling with reduced left ventricular mass and improved function. Numerous retrospective studies have shown that pregnancy following bariatric surgery is associated with a reduced risk of developing hypertensive disorders, however, the mechanisms for this are largely unknown. In pathological pregnancy complicated by pre-eclampsia or growth restriction, studies have shown cardiovascular alterations in haemodynamic indices, cardiac geometry and function, highlighting the importance of the cardiovascular adaptation to pregnancy. This study is a prospective, observational study aiming to investigate the maternal cardiovascular adaptation to pregnancy in women with previous bariatric surgery compared to women with similar early pregnancy BMI and similar pre-surgery BMI. In addition, we investigated the cardiovascular adaptation to pregnancy in obese pregnant women compared to normal BMI pregnant women and the placental function in obese pregnant women and its association with cardiovascular parameters. Cardiovascular function was assessed at three time points during pregnancy by measuring blood pressure and using transthoracic echocardiography to assess haemodynamic function, cardiac geometry and systolic and diastolic function.

Το κείμενο είναι πλούσιο σε παραδείγματα φυλετικής και σεξουαλικής μικρο-επιθετικότητας (microaggression), όπως αυτή ορίζεται από την Κριτική Θεωρία για τη Φυλή. Τα παραδείγματα αυτά δείχνουν την διαθεματική καταπίεση των δύο χαρακτήρων, ενώ την ίδια στιγμή και οι δύο χαρακτήρες καταπιέζονται και φιμώνονται καθώς δεν τους δίνεται η ευκαιρία να αντιπροσωπεύουν τους εαυτούς τους και να μιλήσουν γι’ αυτούς. Παρόλα αυτά, το καταπιεσμένο υποκείμενο δύναται να μιλήσει σε ένα διαθεματικό και ασφαλές μέρος, το οποίο οι δύο πρωταγωνίστριες δημιουργούν οι ίδιες για τους εαυτούς τους, και όπου η ύπαρξη πολλαπλών ταυτοτήτων αντιμετωπίζεται με σεβασμό και ισότητα. Τέλος, υποστηρίζω ότι τα εφηβικά μυθιστορήματα μπορούν να χρησιμοποιηθούν σαν εκπαιδευτικό υλικό στην εκπαίδευση με σκοπό την καταπολέμηση του ρατσισμού και της ομοφοβίας, καθώς οι εκπαιδευτικοί και τα εκπαιδευτικά ιδρύματα είναι από τα πρωταρχικά μέρη όπου μπορεί να αντιμετωπιστεί η συστημική καταπίεση.
description: The current thesis focuses on the discussion of two Young Adult Novels, Juliet Takes a Breath by Gabby Rivera published in 2016 and The Lesbiana’s Guide To Catholic School by Sonora Reyes published in 2022, and sheds light on the two main characters’ Latina identity and queer sexuality. The two protagonists, Juliet and Yami, are discriminated against on the basis of their race and sexuality and are therefore considered as unassimilated to the mainstream, predominantly white and heteronormative community. Multiple examples of racial and sexuality-related microaggressions, as defined by the Critical Race Theory, throughout both books showcase the two main characters’ intersectional oppression, while at the same time both characters are silenced since they are not given the chance to represent themselves, or raise their voices. However, the subaltern is able to talk in the intersectional, safe spaces they create for themselves, where the existence of multiple identities is treated with respect and equality. Finally, I argue that Young Adult novels are able to be used as material in education in order to combat racism and homophobia, as educational institutions are the first spaces where such systemic oppression can be dealt with.

description: I had intended originally to write on another subject and had begun the research. However, in the process of perusing sources available, a related subject captured my interest. The Mormon prophecy relating to the Civil War had been a source of my belief in the efficacy of latter-day revelation. I was under the impression that my Church was extremely interested in current events as indication of the fulfillment of prophecy. I theorized that if such a direct, detailed prophecy as the one received in 1832 by Joseph Smith, began to unfold in our day, considerable excitement would be aroused. Perhaps there was a great deal to understand about the Mormon reaction in 1861.

Exploring variability in medical imaging

description: Although recent successes of deep learning and novel machine learning techniques improved the perfor- mance of classification and (anomaly) detection in computer vision problems, the application of these methods in medical imaging pipeline remains a very challenging task. One of the main reasons for this is the amount of variability that is encountered and encapsulated in human anatomy and subsequently reflected in medical images. This fundamental factor impacts most stages in modern medical imaging processing pipelines. Variability of human anatomy makes it virtually impossible to build large datasets for each disease with labels and annotation for fully supervised machine learning. An efficient way to cope with this is to try and learn only from normal samples. Such data is much easier to collect. A case study of such an automatic anomaly detection system based on normative learning is presented in this work. We present a framework for detecting fetal cardiac anomalies during ultrasound screening using generative models, which are trained only utilising normal/healthy subjects. However, despite the significant improvement in automatic abnormality detection systems, clinical routine continues to rely exclusively on the contribution of overburdened medical experts to diagnosis and localise abnormalities. Integrating human expert knowledge into the medical imaging processing pipeline entails uncertainty which is mainly correlated with inter-observer variability. From the per- spective of building an automated medical imaging system, it is still an open issue, to what extent this kind of variability and the resulting uncertainty are introduced during the training of a model and how it affects the final performance of the task. Consequently, it is very important to explore the effect of inter-observer variability both, on the reliable estimation of model’s uncertainty, as well as on the model’s performance in a specific machine learning task. A thorough investigation of this issue is presented in this work by leveraging automated estimates for machine learning model uncertainty, inter-observer variability and segmentation task performance in lung CT scan images. Finally, a presentation of an overview of the existing anomaly detection methods in medical imaging was attempted. This state-of-the-art survey includes both conventional pattern recognition methods and deep learning based methods. It is one of the first literature surveys attempted in the specific research area.

A trusted infrastructure for symbolic analysis of event-based web APIs
Creators: name: Cunha Sampaio, Gabriela
Publisher: name: Imperial College London
Year: 2022

description: JavaScript has been widely adopted for the development of Web applications, being used for both client and server-side code. Client-side JavaScript programs commonly interact with Web APIs, for instance, to capture the user interaction with the Web page via events. The use of such APIs increases the complexity of JavaScript programs. In fact, most errors in these programs are caused by the misuse of Web APIs. There are several approaches for detecting errors in client-side JavaScript programs, but they either assume the use of a single API or do not model APIs faithfully, giving rise to inconsistent behaviour and lack of trust. We address the problem by developing a trustworthy infrastructure for the static analysis of Web APIs. We focus on two aspects of JavaScript programs: event-driven and message-passing programming, as these paradigms are common sources of confusion among developers. We choose to target the DOM event model and the JavaScript Promises and JavaScript async/await, which facilitate event-driven programming. Additionally, we target the message-passing model of the WebMessaging and WebWorkers APIs. We design formal semantics for events and message-passing to capture fundamental operations required by those APIs, and API reference implementations which are trustworthy in that they follow the respective standards and have been thoroughly tested against their official test suites. Using our formal semantics and reference implementations, we develop JaVerT.Click, the first static symbolic execution tool for JavaScript supporting both event-based and message-passing APIs. We evaluated both the reference implementations and the symbolic execution engine of JaVerT.Click. By testing the reference implementations against their official test suites, we found coverage gaps and issues in the test suites, most of which have been since fixed. By testing the symbolic execution engine against three open-source libraries, we established the bounded correctness of functional properties and found real bugs.

Schurly you're joking - quantum-classical correspondence in phase space for non-Hermitian systems
Creators: name: Hall, Joseph
Publisher: name: Imperial College London
Year: 2022

description: In closed quantum systems described by Hermitian Hamiltonians the Husimi distributions of stationary states are closely related to classical phase space structures. To each state there is assigned a unique area of the Planck cell partitioned phase space. The localisation of the stationary states upon specific regions of phase space can be related to the classical dynamics and energies. In systems described by non-normal operators, and in particular non-Hermitian Hamiltonians, the general non-orthogonality of the stationary states stands in the way of the application of many standard ideas of quantum-classical correspondence. Many of these can be recovered if the Schur vectors are used instead of the eigenvectors. For specific classes of non-Hermitian systems, with simple loss profiles, this correspondence between the Schur vectors and features of the classical phase space are well investigated. For general non-Hermitian systems with more complex gain-loss profiles, however, there is a lack of methods and understanding. In this thesis we will address this problem by associating to each Schur vector an area of phase space described by the classical analogue of the quantum norm, which we describe as classical norm maps. An algorithm will be introduced that constructs from the norm maps a classical density that shows remarkably close correspondence to the Husimi distributions of the Schur vectors. We will demonstrate this correspondence in both regular and chaotic non-Hermitian systems.
