Precise abstract interpretation of hardware designs
Keywords: Abstract Interpretation
Safety Property
Formal verification
CDCL SAT Solver

This dissertation shows that the bounded property verification of hardware Register Transfer Level (RTL) designs can be efficiently performed by precise abstract interpretation of a software representation of the RTL.
The first part of this dissertation presents a novel framework for RTL verification using native software analyzers. To this end, we first present a translation of the hardware circuit expressed in Verilog RTL into the software in C called the software netlist. We then present the application of native software analyzers based on SAT/SMT-based decision procedures as well as abstraction-based techniques such as abstract interpretation for the formal verification of the software netlist design generated from the hardware RTL. In particular, we show that the path-based symbolic execution techniques, commonly used for automatic test case generation in system softwares, are also effective for proving bounded safety as well as detecting bugs in the software netlist designs. Furthermore, by means of experiments, we show that abstract interpretation techniques, commonly used for static program analysis, can also be used for bounded as well as unbounded safety property verification of the software netlist designs. However, the analysis using abstract interpretation shows high degree of imprecision on our benchmarks which is handled by manually guiding the analysis with various trace partitioning directives.
The second part of this dissertation presents a new theoretical framework and a practical instantiation for automatically refining the precision of abstract interpretation using Conflict Driven Clause Learning (CDCL)-style analysis. The theoretical contribution is the abstract interpretation framework that generalizes CDCL to precise safety verification for automatic transformer refinement called Abstract Conflict Driven Learning for Safety (ACDLS). The practical contribution instantiates ACDLS over a template polyhedra abstract domain for bounded safety verification of the software netlist designs. We experimentally show that ACDLS is more efficient than a SAT-based analysis as well as sufficiently more precise than a commercial abstract interpreter.

Social Performance

This thesis investigates the aesthetic presence of social performance in six French and Czechoslovak New Wave films of the 1960s. The New Wave was particularly interested in portraying everyday life, and the film corpus studied in this thesis focuses specifically on the representation of the characters' social lives. In addition, the films share the commonality of being made with an aesthetic of authenticity inspired more or less by the 1960s observational documentary genre of cinéma vérité.
In the film corpus, ordinary social situations occupy a more prominent place on screen than usual, and instigate a social kind of engagement with the films. Where narrative context conventionally provides the framework for a character’s actions, in these unconventional films, it is the characters' social environments that more precisely contextualize their way of being. The aim of the thesis is to engage with these social contexts to understand the characters' social behaviours, and to examine how the 'vérité aesthetic' evokes a social kind of reading of the films.
To this end, I develop in the first chapter a Goffmanian approach to the films, inspired by sociologist Erving Goffman's writings on social reality as a performative realm. I use his notions of social performance, social framework, and social perception to engage with each film through what I call a 'social gaze' that inspects the social dynamics of the characters’ behaviours. Over the course of three case study chapters, I apply this approach to the films to unearth and discuss their social range of meaning.
This thesis thus aims to contribute both to film historical scholarship on the 1960s European New Wave, and to a study of the aestheticization of social reality in film in general.
Education and the sacred: Judaic holiness and the dynamics of teaching and learning
Keywords: religious education
sacred

This thesis explores the nature and dynamics of the relationship between Judaic holiness and Jewish teaching and learning practices. One way of examining this relationship is by focusing on sacred content. The contribution of this thesis is to go beyond sacred content to also focus on teaching as a sacred act—in other words, approaching teaching as sacred, rather than teaching the sacred. Findings build upon and reinforce existing literature on Judaic holiness, but make an original contribution by placing these perspectives in a specifically educative context.
I investigated this relationship from an ethnographic perspective, attending three Orthodox Jewish learning communities (yeshivot) in Jerusalem over a period of six months. Acting as participant observer, I attended classes, studied with students, collected artifacts, took daily field notes and conducted in-depth qualitative interviews. As I analyzed fieldwork data together with relevant academic literature and sacred Jewish texts, a number of key themes emerged. These themes are described in three findings chapters. They outline methodological, experiential, teleological, relational, environmental, structural and theological dimensions of the sacred in Jewish educative practice. From the perspective of study participants, teaching and learning are not only related to the sacred, but themselves constitute a sacred act.
While academic literature tends to focus on the human elements of sanctity, and confessional religious literatures on its theistic dimensions, this thesis illustrates a dynamic way of dovetailing these two approaches. Considered from the Judaic perspectives of study participants, the sanctity of teaching and learning is seen to be both contingent upon human, volitional action as well as a connection to God. Such actualized sanctification is believed to affect and even qualitatively alter the nature of educative methods, environments, encounters and, ultimately, the ontology and capacity of both teachers and learners. This has implications for educative practice more broadly conceived, including insights on the role of a teacher in the student-teacher relationship, an alternative perspective on learning outcomes, a remembrance-oriented epistemology, a teleological connection between teaching and learning and the value of struggle in the learning process.
Circuit quantum acoustodynamics with surface acoustic waves
Keywords: Superconducting qubits
Surface acoustic waves

A highly successful architecture for the exchange of single quanta between coupled quantum systems is circuit quantum electrodynamics (QED), in which the electrical interaction between a qubit and a high-quality microwave resonator offers the possibility to reliably control, store, and read out quantum bits of information on a chip. This architecture has also been implemented with mechanical resonators, showing that a vibrational mode can in principle be manipulated via a coupled qubit. The work presented in this thesis consists of realising an acoustic version of circuit QED that we call circuit quantum acoustodynamics (QAD), in which a superconducting qubit is piezoelectrically coupled to an acoustic cavity based on surface acoustic waves (SAWs).
Designing and building this novel platform involved the following main accomplishments: a systematic characterisation of SAW resonators at low temperatures; successfully developing a recipe for the fabrication of Josephson junction on quartz and diamond; measuring the coherence time of superconducting 3D transmon qubits on these substrates and demonstrating the dispersive coupling between a SAW cavity and a qubit on a planar geometry.
This thesis presents evidence of the coherent interaction between a SAW cavity and a superconducting qubit in several ways. First of all, a frequency shift of the mechanical mode as a function of qubit frequency is observed. We also measure the acoustic Stark shift of the qubit due to the population of the SAW cavity. The extracted coupling is in agreement with theoretical expectations. A time delayed acoustic Stark shift serves to further demonstrate that the Stark shifts that we observe are indeed due to the acoustic field of the SAW mode. The dispersive coupling between these two quantum systems offers the possibility to perform qubit spectroscopy using the SAW resonator as readout component, indicating that these acoustic resonators can, in principle, be adopted as an alternative qubit readout scheme in quantum information processors.
We finally present preliminary measurements of the direct coupling between a SAW resonator and a transmon on diamond, suggesting that strong coupling can in principle be obtained.
Mountain and sea: settlement and economy in late antique Lycia, Isauria and north central Anatolia

This thesis is an interdisciplinary comparative analysis of the socio-economic developments of three regions in Anatolia: Lycia, Isauria and north central Anatolia in the late antique period (c. AD 330-600s). I present the most up-to-date picture of late antique settlement in these regions by collating recent evidence, particularly amphorae and settlement remains, derived from research conducted in these regions over the past few decades. From this picture, I analyse what the location of settlement and archeological remains within sites may reveal concerning the ways in which settlements participated in local, region and interregional exchange networks.
As these three regions share the common geographic features of bordering major maritime areas and encompassing mountainous interiors, I examine how geography may have impacted the location of settlement and the movement of goods and people. By integrating areas located on opposite Anatolian coastlines, I examine how differing maritime networks may have impacted settlement development. This tripartite comparison attempts to establish northern Anatolia alongside its southern counterpart in the discourse of late antique economy and settlement development.
Alongside this regional analysis, I discuss methodological considerations, such as the ways in which the current state of research and various research methods impact our analysis and interpretation of late antique settlement development. This study reveals that sub-regions within Lycia, Isauria and north central Anatolia developed in diverse ways and that the ways in which each region participated in wider exchange differed. I argue that overarching narratives of development, such as 'prosperity' and 'decline' do not accurately reflect the development of these regions. In sum, this thesis contributes an up-to-date analysis of the settlement development of Lycia, Isauria and north central Anatolia to the wider discourse of late antique regional development, which engages and challenges discourse surrounding the economic development of these regions in Late Antiquity.

This research was aimed at determining the ethno-ornithological knowledge of three Mushere villages close to the Dulu Forest, Nigeria to determine whether this might hold potential for developing a local conservation programme to protect the forest. The conservation objective of the research was aimed at determining the drivers of forest degradation, and possible means of mitigation. Using a mixed method approach, quantitative/qualitative data were collected in two years from different demographics (men, women, children, age differentials, occupation, urbanization). Oral interviews, semi-structured interviews, picture elicitation tasks, free-listing exercises and focus group discussions were employed in the data collection process. The findings revealed a relatively low ethno-ornithological knowledge, and a general indifference (ornitho-apatheia) towards birds. Knowledge transmission was predominantly through oral means while TEK acquisition was mainly through vertical and horizontal methods. While adults perceived birds as not valuable, children generally perceived birds as valuable. Cultural utilization and ecological salience were the main drivers of bird naming and knowledge. However, there was a high valuing of the Dulu forest, with the main drivers of the forest degradation being timber extraction. Overall, I concluded that the indifference of the Mushere towards birds revealed a lack of cultural appreciation of birds, leading to little TEK of birds, insufficient to encourage the use of TEK of birds in the conservation of the Dulu forest, and the use of birds as flagship domain for promoting conservation. However, a sustained approach towards encouraging birding activities could improve the perception of birds. I therefore suggest using an ecosystem approach in the conservation of the Dulu forest. Engaging the locals in dialogue, establishing a leadership structure for the management of the Dulu forest, providing alternative means of livelihoods are suggested as ways of mitigating the degradation of the Dulu forest.
A reduced tensor product of braided fusion categories over a symmetric fusion category
Keywords: Topological Field Theory
Modular Tensor Categories
Fusion Categories

The main goal of this thesis is to construct a tensor product on the 2-category BFC-A of braided fusion categories containing a symmetric fusion category A. We achieve this by introducing the new notion of Z(A)-crossed braided categories. These are categories enriched over the Drinfeld centre Z(A) of the symmetric fusion category. We show that Z(A) admits an additional symmetric tensor structure, which makes it into a 2-fold monoidal category. ByTannaka duality, A= Rep(G) (or Rep(G; w)) for a finite group G (or finite super-group (G,w)). Under this identication Z(A) = VectG[G], the category of G-equivariant vector bundles over G, and we show that the symmetric tensor product corresponds to (a super version of) to the brewise tensor product. We use the additional symmetric tensor product on Z(A) to define the composition in Z(A)-crossed braided categories, whereas the usual tensor product is used for the monoidal structure. We further require this monoidal structure to be braided for the switch map that uses the braiding in Z(A).
We show that the 2-category Z(A)-XBF is equivalent to both BFC=A and the 2-category of (super)-G-crossed braided categories. Using the former equivalence, the reduced tensor product on BFC-A is dened in terms of the enriched Cartesian product of Z(A)-enriched categories on Z(A)-XBF.
The reduced tensor product obtained in this way has as unit Z(A). It induces a pairing between minimal modular extensions of categories having A as their Mueger centre.
The relationship between DNA modifications and mutations in cancer

mutational signature

Somatic mutations are the main triggers that initiate the formation of cancer. Large sequencing data sets in recent years revealed a substantial number of mutational processes, many of which are poorly understood or of completely unknown aetiology. These mutational processes leave characteristic sequence patterns, often called "signatures", in the DNA. Characterisation of the mutational patterns observed in cancer patients with respect to different genomic features and processes can help to unravel the aetiology and mechanisms of mutagenesis. Here, we explored the effects of DNA modifications and DNA replication on mutagenesis.
The most common mutation type, C&GT;T mutations in a CpG context, is thought to result from spontaneous deamination of 5-methylcytosine (5mC), the major DNA modification. Much less is known about the mutational properties of the second most frequent modification, 5-hydroxymethylcytosine (5hmC). Integrating multiple genomic data sets, we demonstrate a twofold lower mutagenicity of 5hmC compared to 5mC, present across multiple tissues.
Subsequently, we show how DNA modifications may modulate various mutational processes. In addition to spontaneous deamination of 5mC, our analysis suggests a key role of replication in CpG>TpG mutagenesis in patients deficient in post-replicative proofreading or repair, and possibly also in other cancer patients. Together with an analysis of mutation patterns observed in cancers exposed to UV light, tobacco smoke, or editing by APOBEC enzymes, the results show that the role of DNA modifications goes beyond the well-known spontaneous deamination of 5mC.
Finally, we explored which of the known mutational processes might be modulated by DNA replication. We developed a novel method to quantify the magnitude of strand asymmetry of different mutational signatures in individual patients followed by evaluation of these exposures in early and late replicating regions. More than 75 % of mutational signatures exhibited a significant replication strand asymmetry or correlation with replication timing. The analysis gives new insights into mechanisms of mutagenicity in multiple signatures, particularly the so far enigmatic signature 17, where we suggest an involvement of oxidative damage in its aetiology. In conclusion, our results suggest that DNA replication or replication-associated DNA repair interacts with most mutagenic processes.

Trans-New Guinea languages

This thesis is a descriptive analysis of Wano, a Trans-New Guinea language found in West Papua which is spoken by approximately 7,000 native speakers. The thesis includes: (i) an introduction of Wano topography and demography; a brief ethnographic sketch; some sociolinguistic issues such as name taboo, counting system and kinship terms; and typological profile of the language in chapter 1; (ii) morphophonological properties in chapter 2; (iii) forms and functions of nouns in chapter 3; (iv) verbs in chapter 4; (v) deixis in chapter 5; (vi) clause elements in chapter 6; and (vii) intransitive/transitive non-verbal predication in chapter 7; (viii) clause combination is consecutively observed in terms of coordination and subordination in chapter 8; serial verb constructions in chapter 9; clause linking in chapter 10; and bridging linkage in chapter 11. Chapter 12 sums-up the overall thesis.
Wano has 11 consonantal and 5 vocalic phonemes expressed through their allophonic variations, consonantal assimilation and vocalic diphthongs. The only fricative phoneme attested is bilabial fricative /β/. There are two open and two closed syllable patterns where all consonants are syllable-onset, while approximants can also be syllable-coda. Vowels are syllable-nucleus. Stress is syllable-final which will be penultimate in cliticization. The phonology-morphology interface provides a significant contribution to the shaping of conjugational verbs, which, in turn, plays an essential role to an understanding of Wano verbal system where distinction between roots, stems, citation forms, sequential forms and tense-aspect-mood is defined.
Wano is a polysynthetic language that displays an agglutinative-fusional morphology. Although the alienable-inalienable noun distinction is essentially simple in its morphology, the sex-distinction of the possessor between kin terms allows room for semantic-pragmatic complexity in the interpretation of their various uses. Wano has four non-verbal predications, consists of experiential event, nominal, adjectival, and deictic predicates. Wano is a verb-final language that allows pronominal pro-drop and has no rigid word order for arguments. A clause may consist only of (i) a single verb, (ii) a single inalienable noun, (iii) a serial verb construction, (iv) a combination of an inalienable noun with a verb, and or (v) a combination of an inalienable noun with a serial verb construction. To maintain discourse coherency, Wano makes use of tail-head linkage construction. The thesis consists of: pre-sections (i-xxxiii), contents (1-478), bibliography (479-498), and appendices (499-594) that include verb paradigms, noun paradigms, some oral texts and dialectal wordlist.
Brokerage as an institutional strategy in fragmented fields: the crafting of social entrepreneurship

institutional strategy

Although the scholarship on organizational fields has prevalently focused on emerging, mature and disrupted fields, some social arenas cannot be classified in any of these categories. One such field is that of social entrepreneurship. Despite its progressive establishment and the development of shared norms, understandings, regulations and values governing all of its players, this field still presents unclear boundaries, multiple conceptions, and a high ambiguity in terms of legitimate roles, practices and organizational forms. How can this be the case? The work of some scholars shows that meso-level factors are required to explain the peculiarity of this field. This study builds on their findings and uses the social entrepreneurship field in England as setting to explore how institutional agents can favour the creation of a fragmented field and successfully operate in it. Influencing a fragmented field requires both the creation and the maintenance of a coalition of key stakeholders supporting the enactment of the desired institutional architecture over time. Therefore, this research explores what organizations do to maintain the support of multiple stakeholders in competitive settings and to use the advantages that this creates for sustaining the co-existence of their desired field’s conception and institutional architecture with competing ones. Given the advantages that brokers have in such settings and in pursuing such a strategy, this work makes use of the well-developed literature on brokerage strategies, which focuses on tertius gaudens and tertius iungens strategic orientations, and connects it with that on institutional agency. By using as case studies four brokering agencies active in the social entrepreneurship field in England, this study discovers that combinations of gaudens and iungens strategic orientations, when used by institutional agents, can help them create and sustain over time their sub-field in face of competition. Furthermore, it explores how the co-existence of multiple organizations adopting complementary brokerage strategies as institutional ones, can lead to the creation of a permanently fragmented field. Together, these findings contribute to develop the literature on brokerage, on institutional agency — especially in relation to fragmented fields —, and that on social entrepreneurship.
