description: For a class of flows on polytopes, including many examples from Evolutionary Game Theory, we describe a piecewise linear model which encapsulates the asymptotic dynamics along the heteroclinic network formed out of the polytope's vertexes and edges. This piecewise linear flow is easy to compute even in higher dimensions, which allows the usage of numeric algorithms to find invariant dynamical structures such as periodic, homoclinic or heteroclinic orbits, which if robust persist as invariant dynamical structures of the original flow. We apply this method to prove the existence of chaotic behavior in some Hamiltonian replicator systems on the five dimensional simplex.

description: Derivatives, mostly in the form of gradients and Hessians, are ubiquitous in machine learning. Automatic differentiation (AD), also called algorithmic differentiation or simply "autodiff", is a family of techniques similar to but more general than backpropagation for efficiently and accurately evaluating derivatives of numeric functions expressed as computer programs. AD is a small but established field with applications in areas including computational fluid dynamics, atmospheric sciences, and engineering design optimization. Until very recently, the fields of machine learning and AD have largely been unaware of each other and, in some cases, have independently discovered each other's results. Despite its relevance, general-purpose AD has been missing from the machine learning toolbox, a situation slowly changing with its ongoing adoption under the names "dynamic computational graphs" and "differentiable programming". We survey the intersection of AD and machine learning, cover applications where AD has direct relevance, and address the main implementation techniques. By precisely defining the main differentiation techniques and their interrelationships, we aim to bring clarity to the usage of the terms "autodiff", "automatic differentiation", and "symbolic differentiation" as these are encountered more and more in machine learning settings.

description: Depth first search (DFS) tree is a fundamental data structure for solving various problems in graphs. It is well known that it takes $O(m+n)$ time to build a DFS tree for a given undirected graph $G=(V,E)$ on $n$ vertices and $m$ edges. We address the problem of maintaining a DFS tree when the graph is undergoing {\em updates} (insertion and deletion of vertices or edges). We present the following results for this problem. (a) Fault tolerant DFS tree: There exists a data structure of size ${O}(m ~polylog~ n)$ such that given any set ${\cal F}$ of failed vertices or edges, a DFS tree of the graph $G\setminus {\cal F}$ can be reported in ${O}(n|{\cal F}| ~polylog~ n)$ time. (b) Fully dynamic DFS tree: There exists a fully dynamic algorithm for maintaining a DFS tree that takes worst case ${O}(\sqrt{mn} ~polylog~ n)$ time per update for any arbitrary online sequence of updates. (c) Incremental DFS tree: Given any arbitrary online sequence of edge insertions, we can maintain a DFS tree in ${O}(n ~polylog~ n)$ worst case time per edge insertion. These are the first $o(m)$ worst case time results for maintaining a DFS tree in a dynamic environment. Moreover, our fully dynamic algorithm provides, in a seamless manner, the first deterministic algorithm with $O(1)$ query time and $o(m)$ worst case update time for the dynamic subgraph connectivity, biconnectivity, and 2-edge connectivity.

Subjects: Engineering

description: The main objective of this article is to present a prototype that integrates blockchain and Internet-of-Things (IoT) devices to digitize information across a generic Supply Chain (SC). Blockchain bring many benefits to the operation of improving provenance and reliability, such as, digitizing the interaction among SC actors to allow implementation of smart contracts to support a secure and authenticated chain. In technical terms, blockchain is a decentralized database where information recording is secure and blockchain-based traceability in the SC can address shortcomings that exist in centralized solutions. Provenance could be achieved by implementing SC business logic within smart contracts using blockchains. This article presents an architecture of software that combines blockchain with IoT devices that allows traceability of a generic product from source to destination, through multi-echelon suppliers, logistics, manufacturers to the end-customer. The presented software architecture uses the Solana blockchain for the implementation of SC processes and business logic. This blockchain was selected from a review, reported in this article, of several widely used blockchain networks. It was selected mainly due to its speed and cost of transactions. Within the blockchain we store SC related data and events communicated over the internet and mobile application channels, in a Solana blockchain using Solana’s native blockchain libraries. the IoT devices used are Sigfox cloud gateway, and Sensit that uses LPWAN (Low power wide area network) wireless telecommunication for data transfer. In our IoT device, the blockchain stores temperature, humidity, light, location, tilting, door opening, vibration, and magnetic field. The goal is to use existing technologies to develop a software architecture for a medium term objective of an implementable generic blockchain for SCs.

description: We propose a fully unsupervised method to detect bias in contextualized embeddings. The method leverages the assortative information latently encoded by social networks and combines orthogonality regularization, structured sparsity learning, and graph neural networks to find the embedding subspace capturing this information. As a concrete example, we focus on the phenomenon of ideological bias: we introduce the concept of an ideological subspace, show how it can be found by applying our method to online discussion forums, and present techniques to probe it. Our experiments suggest that the ideological subspace encodes abstract evaluative semantics and reflects changes in the political left-right spectrum during the presidency of Donald Trump.

description: Using small deformations of the total energy, as introduced in [31], we establish that damped second order gradient systems $$u^{\prime\prime}(t)+γu^\prime(t)+\nabla G(u(t))=0,$$may be viewed as quasi-gradient systems. In order to study the asymptotic behavior of these systems, we prove that any (nontrivial) desingularizing function appearing in KL inequality satisfies $φ(s)\ge c\sqrt s$ whenever the original function is definable and $C^2.$ Variants to this result are given. These facts are used in turn to prove that a desingularizing function of the potential $G$ also desingularizes the total energy and its deformed versions. Our approach brings forward several results interesting for their own sake: we provide an asymptotic alternative for quasi-gradient systems, either a trajectory converges, or its norm tends to infinity. The convergence rates are also analyzed by an original method based on a one-dimensional worst-case gradient system.We conclude by establishing the convergence of solutions of damped second order systems in various cases including the definable case. The real-analytic case is recovered and some results concerning convex functions are also derived.
title: The enslavement of war captives by the Romans to 146 BC
Creators: name: Wickham, Jason
Publisher: name: University of Liverpool Repository
Year: 2014

description: War captives are generally thought to have comprised the main portion of the Roman slave supply during the Republic. Likewise, the result of mass enslavement through continuous war has been interpreted as a principle factor in the agricultural evolution in Italy from the second century BC which saw a significant increase in large plantation style farming (latifundia). The misconception of a male bias in agricultural labour has put a heavy influence on the need for an external supply of slaves rather than through reproduction. However, an analysis of documentary evidence suggests that wartime enslavement was more limited. Problems in supervising, transporting, and trading large numbers of slaves, as well as competing markets elsewhere in the Mediterranean, made immediate absorption of captives as slaves into the central Italian economy problematic. Furthermore, the vast majority of wartime enslavements occurred following the capture of cities, where larger numbers of civilian prisoners were taken, mostly comprising women, children and slaves. Ancient sources frequently exaggerated the number of war captives and often neglected to elaborate on the fate of those taken in war. Many modern historians have been far too quick to assume that prisoners were enslaved, which has given a disproportionate view of the importance of the contribution of war captives to the slave supply and their effect upon the growing slave population at Rome during the Republic. Such assumptions have left critical analysis wanting and, as a result, war captives have been largely neglected by Roman historians. This study attempts to address the gap in our analysis of these crucial practices in antiquity and to offer an explanation of how the taking of war captives was impacted by Rome’s changing socio-political and economic structures during the Republic.

description: The discovery of causal relationships from purely observational data is a fundamental problem in science. The most elementary form of such a causal discovery problem is to decide whether X causes Y or, alternatively, Y causes X, given joint observations of two variables X, Y. An example is to decide whether altitude causes temperature, or vice versa, given only joint measurements of both variables. Even under the simplifying assumptions of no confounding, no feedback loops, and no selection bias, such bivariate causal discovery problems are challenging. Nevertheless, several approaches for addressing those problems have been proposed in recent years. We review two families of such methods: Additive Noise Methods (ANM) and Information Geometric Causal Inference (IGCI). We present the benchmark CauseEffectPairs that consists of data for 100 different cause-effect pairs selected from 37 datasets from various domains (e.g., meteorology, biology, medicine, engineering, economy, etc.) and motivate our decisions regarding the "ground truth" causal directions of all pairs. We evaluate the performance of several bivariate causal discovery methods on these real-world benchmark data and in addition on artificially simulated data. Our empirical results on real-world data indicate that certain methods are indeed able to distinguish cause from effect using only purely observational data, although more benchmark data would be needed to obtain statistically significant conclusions. One of the best performing methods overall is the additive-noise method originally proposed by Hoyer et al. (2009), which obtains an accuracy of 63+-10 % and an AUC of 0.74+-0.05 on the real-world benchmark. As the main theoretical contribution of this work we prove the consistency of that method.

description: Loose Legendrian n-submanifolds, for n at least 2, were introduced by Murphy and proved to be flexible in the h-principle sense: any two loose Legendrian submanifolds that are formally Legendrian isotopic are also actually Legendrian isotopic. Legendrian contact homology is a Floer theoretic invariant that associates a differential graded algebra (DGA) to a Legendrian submanifold. The DGA of a loose Legendrian submanifold is trivial.
description: The main result in the paper is wrong. The Legendrian spheres claimed to be non-loose are in fact loose. The author thanks Emmy Murphy showing that the spheres are loose

Structure formation in a mixed dark matter model with decaying sterile neutrino: the 3.5 keV X-ray line and the Galactic substructure

description: We perform a set of cosmological simulations of structure formation in a mixed dark matter (MDM) model. Our model is motivated by the recently identified $3.5\,{\rm keV}$ X-ray line, which can be explained by the decay of non-resonantly produced sterile neutrinos accounting for $20$-$60\%$ of the dark matter in the Universe. These non-resonantly produced sterile neutrinos have a sizable free-streaming length and hence behave effectively as warm dark matter (WDM). Assuming the rest of dark matter is composed of some cold dark matter (CDM) particles, we follow the coevolution of a mixed WDM plus CDM cosmology. Specifically, we consider the models with the warm component fraction of $r_{\rm warm}=0.25$ and $0.50$. Our MDM models predict that the comoving Jeans length at the matter-radiation equality is close to that of the thermally produced warm dark matter model with particle mass $m_{\rm WDM}=2.4\,{\rm keV}$, but the suppression in the fluctuation power spectrum is weaker. We perform large $N$-body simulations to study the structure of non-linear dark halos in the MDM models. The abundance of substructure is significantly reduced in the MDM models, and hence the so-called small-scale crisis is mitigated. The cumulative maximum circular velocity function (CVF) of at least one halo in the MDM models is in good agreement with the CVFs of the observed satellites in the Milky Way and the Andromeda galaxy. We argue that the MDM models open an interesting possibility to reconcile the reported $3.5\,{\rm keV}$ line and the internal structure of galaxies.

description: One of the most computationally intensive operations in digital image/video processing systems is multi-dimensional convolution. Every image/video processor needs the convolution module in its pre-processing stage. Fast and efficient design of the convolution module in an application specific system is a great challenge in VLSI (Very Large Scale Integration) design. Convolution operator requires a large set of multipliers and accumulators. A high precision multiplier takes enormous amount of VLSI area and it consumes more power. Hence reduction of the number of multipliers is another important challenge in VLSI design. A multiplier-less architecture for the design of a multi-dimensional convolution module is proposed in this thesis. The convolution expression is suitably partitioned to make it appropriate for overall pipelining and internal parallelism in the architecture design. An absolute flexibility is provided in the architecture for choosing the kernel characteristics in the convolution module.

A novel architecture for performing convolution with symmetric kernels is also proposed in this thesis. This quadrant symmetric architecture exploits the symmetry of the kernels and performs computation with one quarter area of the kernel. Since the kernel characteristics are the same in all other three quarters, the intermediate results are reused and manipulated accordingly to obtain the final convolution result. This design reduces the VLSI area by about 75%.

A new concept of log2 and inverse-log2 computation by an approximation process is also presented in this research. This leads to the elimination of the need for multipliers in the generic architecture by employing only adders and shifters for computation. The proposed architectures are implemented in a FPGA (Field Programmable Gate Array) environment on Xilinx's Virtex II 2v2000ff896-4 chip with a clock frequency of 99 MHz. It is observed that the new design reduces the VLSI area further by about 10% in addition to the reduction of power consumption. It is also observed that the new design could generate an output pixel in every clock cycle.

Research work is in progress to employ the concept of log2 and inverse-log2 computations in building multiplier-less architectures for auto-correlation and cross-correlation functions.

description: This paper presents proof that Buss's $S^2_2$ can prove the consistency of a fragment of Cook and Urquhart's $\mathrm{PV}$ from which induction has been removed but substitution has been retained. This result improves Beckmann's result, which proves the consistency of such a system without substitution in bounded arithmetic $S^1_2$. Our proof relies on the notion of "computation" of the terms of $\mathrm{PV}$. In our work, we first prove that, in the system under consideration, if an equation is proved and either its left- or right-hand side is computed, then there is a corresponding computation for its right- or left-hand side, respectively. By carefully computing the bound of the size of the computation, the proof of this theorem inside a bounded arithmetic is obtained, from which the consistency of the system is readily proven. This result apparently implies the separation of bounded arithmetic because Buss and Ignjatović stated that it is not possible to prove the consistency of a fragment of $\mathrm{PV}$ without induction but with substitution in Buss's $S^1_2$. However, their proof actually shows that it is not possible to prove the consistency of the system, which is obtained by the addition of propositional logic and other axioms to a system such as ours. On the other hand, the system that we have considered is strictly equational, which is a property on which our proof relies.

description: In this paper, we study the challenging problem of categorizing videos according to high-level semantics such as the existence of a particular human action or a complex event. Although extensive efforts have been devoted in recent years, most existing works combined multiple video features using simple fusion strategies and neglected the utilization of inter-class semantic relationships. This paper proposes a novel unified framework that jointly exploits the feature relationships and the class relationships for improved categorization performance. Specifically, these two types of relationships are estimated and utilized by rigorously imposing regularizations in the learning process of a deep neural network (DNN). Such a regularized DNN (rDNN) can be efficiently realized using a GPU-based implementation with an affordable training cost. Through arming the DNN with better capability of harnessing both the feature and the class relationships, the proposed rDNN is more suitable for modeling video semantics. With extensive experimental evaluations, we show that rDNN produces superior performance over several state-of-the-art approaches. On the well-known Hollywood2 and Columbia Consumer Video benchmarks, we obtain very competitive results: 66.9\% and 73.5\% respectively in terms of mean average precision. In addition, to substantially evaluate our rDNN and stimulate future research on large scale video categorization, we collect and release a new benchmark dataset, called FCVID, which contains 91,223 Internet videos and 239 manually annotated categories.

description: There are four positions one might take in respect of the ontological status of the physical world: physicalism, which says that the physical world is ontologically fundamental, and nothing else is; substance dualism, which says that the physical world is ontologically fundamental, but so is the human mental realm, and that these are in some strong metaphysical sense separate; idealism, which says that the physical world is constitutively sustained, at least in part, by facts about the human mental realm; and a rough collection of views I term 'compatibilism', which holds that both the physical and the mental are fundamental, but that they are not separate as in substance dualism. Of these positions, I argue mainly against the first and last. I begin by demonstrating that all forms of compatibilism are committed to a radically revisionary definition of 'mental' and 'physical', since in ordinary usage, and for good reason, the terms are taken as mutually exclusive. I formulate a definition of 'mental' according to which it means 'subjective, non-spatial, and non-quantifiable', and demonstrate that these properties are necessarily coextensive. Against physicalism, I consider a range of arguments which purport to show that physical space, as a necessary feature of the physical world, cannot be ontologically fundamental, concluding that physical space, or at least the physical space that we are interested in, must be the one which we inhabit, and that our relationship of inhabitancy of this physical space plays a constitutive role in it. Since this assumes that physical space must be in some way constituted rather than fundamental, I finish by refuting a set of strategies which attempt to show that physical space itself must be constituted.

description: We consider single-hop radio networks with multiple channels as a model of wireless networks. There are $n$ stations connected to $b$ radio channels that do not provide collision detection. A station uses all the channels concurrently and independently. Some $k$ stations may become active spontaneously at arbitrary times. The goal is to wake up the network, which occurs when all the stations hear a successful transmission on some channel. Duration of a waking-up execution is measured starting from the first spontaneous activation. We present a deterministic algorithm for the general problem that wakes up the network in $O(k\log^{1/b} k\log n)$ time, where $k$ is unknown. We give a deterministic scalable algorithm for the special case when $b>d \log \log n$, for some constant $d>1$, which wakes up the network in $O(\frac{k}{b}\log n\log(b\log n))$ time, with $k$ unknown. This algorithm misses time optimality by at most a factor of $O(\log n(\log b +\log\log n))$, because any deterministic algorithm requires $Ω(\frac{k}{b}\log \frac{n}{k})$ time. We give a randomized algorithm that wakes up the network within $O(k^{1/b}\ln \frac{1}ε)$ rounds with a probability that is at least $1-ε$, for any $0\log(128b\log n)$, both with a probability that is at least $1-1/\mbox{poly}(n)$.

title: Augustus and the Roman provinces of Iberia
Creators: name: Griffiths, David
Publisher: name: University of Liverpool Repository
Year: 2014

description: This thesis explores two key themes: (1) the social, cultural and economic changes in the Roman provinces of Spain during the last half of the first century BC and the early first century AD, and the direct effect that Augustus had in driving these developments; (2) the significance that the provinces of Spain had for Augustus and Rome. Initially we assess the exploitation of the Cantabrian War for the military image of Augustus, suggesting that the conflict played a crucial role in bolstering the position of the princeps following the Civil Wars and the constitutional arrangements reached with the senate up to 27. From here in turn we consider the manner in which Augustan action within Iberia impacted upon the literary and visual depictions of the peninsula. The thesis also highlights the fiscal imperatives that acted as a driving force behind the growth in urbanisation, the widespread promotion of privileged status and the provincial reorganisations of Augustus. Following this, the surge in monumentalisation across Hispania’s towns and cities is treated, placing a renewed emphasis on the role of the Augustan regime in encouraging, if indirectly, these processes. An assessment of the impact of Augustan rule on the upward mobility of the Spanish elites follows, highlighting patronage and wealth as the twin pillars of Spanish advancement and suggesting that the first princeps is instrumental in laying the groundwork for the expanding promotion of Spaniards during the reigns of his immediate successors. Finally, the thesis concludes with an overview of the nascent imperial cult in Spain, suggesting in the first instance that the imposition of the cult in the north-west aided the suppression of the recalcitrant tribes and may very well have impacted upon Augustan policies in similarly unstable areas such as Germany and Gaul; and secondly, that whilst direct compulsion cannot be countenanced, Augustus’ dissemination of civic organisation created a framework within which elite competition ensured the rapid proliferation of the imperial cult throughout the towns and cities of Spain and the western provinces.

title: Atomic layer deposition and metal organic chemical vapour deposition of materials for photovoltaic applications
Creators: name: Hindley, Sarah
Publisher: name: University of Liverpool Repository
Year: 2014

description: In this thesis, the development of thin films and nanostructures prepared with chemical vapour techniques are investigated for applications in photovoltaics. The deposition of both p-type and n-type oxides are investigated as a means of preparing all oxide p-n junctions. Both CVD and ALD precursors and processes have been developed. Zinc oxide nanowires are of interest as an n-type absorber layer with high surface area. In this thesis, the crystal structures of DEZn and DMZn were revisited and a new understanding of conventional zinc CVD precursors is presented. For DEZn a single structure was isolated and characterised with single crystal XRD. In the case of DMZn two temperature dependant structures were identified: namely α and β at 200K and 150K respectively. The DMZn precursor was subsequently exploited in a series of adduct-based precursors of the notation [DMZn.L] (where L = 1,2-dimethoxyethane, 1,4-dioxane and 1,4-thioxane). The crystal structures of these precursors were determined, and they were subsequently used to grow ZnO and sulphur doped ZnO across a range of CVD growth conditions. The microstructure and electronic properties of the nanowires have been characterised with electron microscopy, x-ray diffraction, Raman spectroscopy and photoluminescence. The II:VI ratio and substrate temperatures were both confirmed as playing a significant role in determining the microstructure of the nanowires. It has been demonstrated that the use of [DMZn.L] can avoid the pre-reaction between DMZn and oxygen. The studies with the thioxane adduct suggests the involvement of the ligand and hence sulphur incorporation in the nanowires. Two copper precursors were selected as the basis of p-type copper oxide film studies. The first Cu(hfac)(COD) has been used previously to deposit copper oxide by conventional CVD. In this thesis it is demonstrated for the first time that a pulsed LI-ALD approach can be exploited to deposit CuO with ozone as the co-reagent. An unexpected outcome of the research was the successful growth of electrically conductive copper metal films with a sheet resistance of 0.83Ω/□ when the precursor was thermally decomposed. The second copper precursor, namely CpCu(tBuNC) was used in atomic layer deposition to successfully deposit CuO or Cu2O with oxygen plasma and water respectively. Having identified that the β-diketonate compound yielded copper, the cyclopentadienyl based precursor was investigated as a route for the deposition of conductive copper metal films. Both thermal decomposition and a hydrogen plasma ALD process have been shown to deposit copper. With the plasma process, deposition of copper was demonstrated as low as 75˚C with a sheet resistance of only 0.55Ω/□. This thesis has demonstrated novel deposition routes for p- and n-type oxide materials which have potential future applications in thin film or nanostructured photovoltaic technology.

description: We present an algebraic method to study four-dimensional toric varieties by lifting matrix equations from the special linear group ${\rm SL}_2({\mathbb Z})$ to its preimage in the universal cover of ${\rm SL}_2({\mathbb R})$. With this method we recover the classification of two-dimensional toric fans, and obtain a description of their semitoric analogue. As an application to symplectic geometry of Hamiltonian systems, we give a concise proof of the connectivity of the moduli space of toric integrable systems in dimension four, recovering a known result, and extend it to the case of semitoric integrable systems with a fixed number of focus-focus points and which are in the same twisting index class. In particular, we show that any semitoric system with precisely one focus-focus singular point can be continuously deformed into a system in the same isomorphism class as the Jaynes-Cummings model from optics.

description: Given that virtually all college and university students are required to complete courses in college composition, courses designed to prepare them to think and write in approved academic language, the field is a fertile one for feminist inquiry. Recent work on feminist epistemology and writing theory, combined with Richard Fulkerson's proposed four-part construct of any composition theory, can be used to examine the conventions of argumentative writing. Such writing typically uses adversarial metaphors, often privileges abstract conceptions of knowledge and, furthermore, may be based on metaphors for reason which denigrate emotion and exclude women. New techniques for writing about conflict, such as Josina Makau's "cooperative argumentation" and Catherine Lamb's use of mediation and negotiation in the writing process, may help our students understand that academic writing can integrate the "objective" with the "subjective" to create knowledge.

description: In this paper, we investigate the geometry of the orbit space of the closure of the subscheme parametrizing smooth Fano Kähler-Einstein manifolds inside an appropriate Hilbert scheme. In particular, we prove that being K-semistable is a Zariski open condition and establish the uniqueness for the Gromov-Hausdorff limit for a punctured flat family of Fano Kähler-Einstein manifolds. Based on these, we construct a proper scheme parameterizing the S-equivalent classes of $\QQ$-Gorenstein smoothable, K-semistable Fano varieties, and verify various necessary properties to guarantee that it is a good moduli space.

description: INTRODUCTION

In forensic investigations concerning animal abuse and biodiversity preservation, DNA analysis is frequently employed. It can be used to look into crimes including poaching, illegal trade in protected species, habitat devastation, unlawful gathering, and maltreatment. Moreover, DNA analysis can be used to ascertain an animal's species, place of origin, and genetic relationships with other animals. For the purpose of genetic species identification, nuclear and mitochondrial markers can be employed.

description: The wellbeing of university students has long been a topic of interest, with growing concerns regarding the impact Higher Education can have on the mental and physical health of young adults. The recent Covid-19 pandemic has been a draining addition to the list of issues significantly impacting the quality of life and wellbeing of young adults. This research aims to identify how exactly the Covid-19 pandemic has affected the lives of university students in Scotland as well as understand if physical activity can be used as a method of mitigating these negative impacts. As issues around Covid-19 and its effect are still unfolding, this study presents a unique contribution at the cutting edge of research looking at how Covid-19 has impacted students’ lives in Scotland and if and how students themselves choose to manage their wellbeing through sport and exercise. In order to explore this analysis has been conducted on primary data from 310 university students across Scotland. As a result, important relationships have been acknowledged such as specific gendered differences in both wellbeing and anxiety with students who identify as female more significantly affected. Also, variances in wellbeing and anxiety were identified in different years of study, with students in younger years recording worse wellbeing and students near the end of the studies recording worse anxiety. Additionally, a strong, positive relationship was identified between subjective wellbeing and physical activity. However, this research also has its limitations, such as the fact that although the sample size was large enough to test for statistical significance, the sample of transgender and non-binary students was very small, leaving room for improvement through further, more detailed research on this issue. Furthermore, even though this research shows a mostly positive relationship between wellbeing and exercise, limited data shows a potentially negative relationship, requiring further investigation in this area. As a result, this project can be used as a foundation to further investigate and understand both the short-term and long-term impacts of Covid-19 on mental health and student wellbeing as well as how physical activity can be used as a method of improving ones physical and mental health.

description: Small-molecule inducible degrons allow the conditional degradation of genetically modified proteins in diverse models from human cell lines to mice. However, these approaches vary in selectivity, potency, and suitability and have various limitations. In this thesis, we describe the development of BromoTag, a novel inducible degron system that consists of a BRD4 bromodomain variant that can be recruited to the VHL E3 ligase via new bumped proteolysis targeting chimaeras (PROTACs) to induce the degradation of the genetically engineered protein target. We developed an endogenous BromoTag platform that we used in the extensive optimisation of BromoTag bump-and-hole-PROTACs. Our cellular data collectively qualify PROTAC AGB1, a potent, rapid, and selective degrader of BromoTagged proteins. Furthermore, we established the mechanism of action underpinning AGB1’s exceptional activity and its aptness for application in human cell models due to its low cellular cytotoxicity and limited off-target activity.

Further favourable pharmacokinetic profile in mice established AGB1’s suitability for in vivo application. We found an optimal CRISPR strategy for the homozygous integration of the BromoTag into HEK293, which we used to create and validate homozygous BromoTag knock-in HEK293 cell lines against targets MCM4, BRD4 and BRD2. We used these knock-in cell lines to demonstrate rapid, conditional degradation of BromoTagged proteins while targeting distinct and essential cellular processes. To probe the functional consequences of rapid, profound target depletion, we performed for the first time an unbiased proteomic analysis of a selectively degraded BRD4 to identify and characterise BRD4 regulated proteins. We found from this analysis potentially novel roles for previously identified BRD4 associating proteins ARC and CyclinT2.

This study demonstrates the development and application of the BromoTag, a small molecule induced degron that complements the arsenal of established degradation tools, providing scientists with a complementary and robust approach for interrogating the biological function of potentially therapeutic proteins in cells and in vivo.

description: Following previous work of the second author, we establish more properties of groups of circle homeomorphisms which admit invariant laminations. In this paper, we focus on a certain type of such groups-so-called pseudo-fibered groups, and show that many 3-manifold groups are examples of pseudo-fibered groups. We then prove that torsion-free pseudo-fibered groups satisfy a Tits alternative. We conclude by proving that a purely hyperbolic pseudo-fibered group acts on the 2-sphere as a convergence group. This leads to an interesting question if there are examples of pseudo-fibered groups other than 3-manifold groups.
