title: Bioinformatics methods for annotating genomes using proteomic data
Creators: name: Daniel Naguib, Gianluca
Publisher: name: University of Liverpool Repository
Year: 2015

description: In recent years the number of genome sequencing projects has been exponentially increasing, leaving genome annotation dependent upon primarily automated tools. Recently, proteogenomics studies have attempted to bridge the gap between genomics and proteomics, by actively using proteomic data during the annotation stage. This project attempts to address some limitations in current bioinformatics approaches, such as the identification of N-terminal peptides and those spanning across exons – so called intron-spanning peptides (ISPs). Additionally it presents approaches for determining the quality of gene models. The results provide insights on the N-terminus of proteins (identification strategies, modifications), quality assessment on available gene annotation and performance of gene finders. A new method has also been developed for the identification of ISPs and, although this technique remains challenging, provides a framework in which future developments can be made.

description: Let $t$ be random and uniformly distributed in the interval $[T,2T]$, and consider the quantity $N(t+1/\log T) - N(t)$, a count of zeros of the Riemann zeta function in a box of height $1/\log T$. Conditioned on the Riemann hypothesis, we show that the probability this count is greater than $x$ decays at least as quickly as $e^{-Cx\log x}$, uniformly in $T$. We also prove a similar results for the logarithmic derivative of the zeta function, and likewise analogous results for the eigenvalues of a random unitary matrix. We use results of this sort to show on the Riemann hypothesis that the averages $$ \frac{1}{T} \int_T^{2T} \Bigg| \frac{ζ\Big(\frac{1}{2} + \fracα{\log T} + it\Big)}{ζ\Big(\frac{1}{2}+ \fracβ{\log T} + it\Big)}\Bigg|^m\,dt $$ remain bounded as $T\rightarrow\infty$, for $α, β$ complex numbers with $β\neq 0$. Moreover we show rigorously that the local distribution of zeros asymptotically controls ratio averages like the above; that is, the GUE Conjecture implies a (first-order) ratio conjecture.

title: Decentralised Coalition Formation Methods for Multi-Agent Systems
Creators: name: Riley, Luke
Publisher: name: University of Liverpool Repository
Year: 2015

description: Coalition formation is a process whereby agents recognise that cooperation with others can occur in a mutually beneficial manner and therefore the agents can choose appropriate temporary groups (named coalitions) to form. The benefit of each coalition can be measured by: the goals it achieves; the tasks it completes; or the utility it gains. Determining the set of coalitions that should form is difficult even in centralised cooperative circumstances due to: (a) the exponential number of different possible coalitions; (b) the ``super exponential'' number of possible sets of coalitions; and (c) the many ways in which the agents of a coalition can agree to distribute its gains between its members (if this gain can be transferred between the agents). The inherent distributed and potentially self-interested nature of multi-agent systems further complicates the coalition formation process. How to design decentralised coalition formation methods for multi-agent systems is a significant challenge and is the topic of this thesis. The desirable characteristics for these methods to have are (among others): (i) a balanced computational load between the agents; (ii) an optimal solution found with distributed knowledge; (iii) bounded communication costs; and (iv) to allow coalitions to form even when the agents disagree on their values. The coalition formation methods presented in this thesis implement one or more of these desirable characteristics. The contribution of this thesis begins with a decentralised dialogue game that utilise argumentation to allow agents to reason over and come to a conclusion on what are the best coalitions to form, when the coalitions are valued qualitatively. Next, the thesis details two decentralised algorithms that allow the agents to complete the coalition formation process in a specific coalition formation model, named characteristic function games. The first algorithm allows the coalition value calculations to be distributed between the agents of the system in an approximately equal manner using no communication, where each agent assigned to calculate the value of a coalition is included in that coalition as a member. The second algorithm allows the agents to find one of the most stable coalition formation solutions, even though each agent has only partial knowledge of the system. The final contribution of this thesis is a new coalition formation model, which allows the agents to find the expected payoff maximising coalitions to form, when each agent may disagree on the quantitative value of each coalition. This new model introduces more risk to agents valuing a coalition higher than the other agents, and so encourages pessimistic valuations.

description: We consider finite area convex Euclidean circular sectors. We prove a variational Polyakov formula which shows how the zeta-regularized determinant of the Laplacian varies with respect to the opening angle. Varying the angle corresponds to a conformal deformation in the direction of a conformal factor with a logarithmic singularity at the origin. We compute explicitly all the contributions to this formula coming from the different parts of the sector. In the process, we obtain an explicit expression for the heat kernel on an infinite area sector using Carslaw-Sommerfeld's heat kernel. We also compute the zeta-regularized determinant of rectangular domains of unit area and prove that it is uniquely maximized by the square.

description: We investigate the current debate on the Mn valence in Ga$_{1-x}$Mn$_x$N, a diluted magnetic semiconductor (DMSs) with a potentially high Curie temperature. From a first-principles Wannier-function analysis, we unambiguously find the Mn valence to be close to $2+$ ($d^5$), but in a mixed spin configuration with average magnetic moments of 4$μ_B$. By integrating out high-energy degrees of freedom differently, we further derive for the first time from first-principles two low-energy pictures that reflect the intrinsic dual nature of the doped holes in the DMS: 1) an effective $d^4$ picture ideal for local physics, and 2) an effective $d^5$ picture suitable for extended properties. In the latter, our results further reveal a few novel physical effects, and pave the way for future realistic studies of magnetism. Our study not only resolves one of the outstanding key controversies of the field, but also exemplifies the general need for multiple effective descriptions to account for the rich low-energy physics in many-body systems in general.

title: Rome and the Sasanian Empire in the fifth century A.D: a necessary peace
Creators: name: Morley, Craig
Publisher: name: University of Liverpool Repository
Year: 2016

description: Since Ardashir’s victory over the Parthians in A.D 224 to his successors’ eventual defeat at the hands of the Arabs in 651 the Roman and Sasanian Empires had been bitter and deadly rivals. Throughout Late Antiquity the Roman-Sasanian relationship was dominated by competition; a constant battle for imperial prestige, military supremacy, cultural influence and economic advantage. In the course of their relationship Ctesiphon, the Sasanian capital, was sacked by Roman forces, the Roman emperor Valerian was captured and taken prisoner, Julian the Apostate was killed by Sassanian forces in his infamous campaign of 363, and the great Roman city of Antioch had been captured and razed. Yet in this seemingly never-ending imperial struggle the fifth century stands out as a period of unprecedented peace between the imperial rivals. It is the aim of this thesis to analyse what made the fifth century a unique period of peace. This thesis seeks to expand on current scholarship on the fifth-century Roman-Sasanian relationship, which has focused on the investigation of specific and individual events, by taking a more holistic approach. In this regard, all aspects of the relationship, military conflicts, frontier zones, barbarian threats, religious issues, economic considerations and the development of diplomatic contacts, will be analysed in order to identify what pushed the two empires towards a peace and, more importantly, how this peace was maintained in the face of old hostilities and traditional antagonism. Viewing the Roman-Sasanian relationship as merely one part of the wider late antique world, not as something unique and separate, will also be a key component of this investigation. Central to the aim and approach of this thesis is the use of political realism, a theory for understanding international relations, to reveal the motivations and pressures that both empires faced in this period that pushed them towards peace. In this regard, it will be argued that the Roman and Sasanian overriding desire and goal of ensuring their own safety and security in an anarchic world in the face of the new and dangerous threats posed by the ascendant Huns, Hephthalites and Vandals was the underlying motivation behind the fifth-century peace. It was the threat posed by these groups that forced a shift in Roman-Sasanian relations towards the accommodation that both needed to survive the turbulent fifth century. As such, it was these new threats that stimulated the development of imperial diplomacy in the fifth century that allowed the two empires to mediate their traditional casus belli and maintain peace throughout this period. This diplomatic development allowed them to reach new and innovative diplomatic solutions to their problems in the frontier zones of Arabia and Armenia.

title: Variational models and numerical algorithms for effective image registration
Creators: name: Ibrahim, Mazlinda
Publisher: name: University of Liverpool Repository
Year: 2016

description: The goal of image registration is to align two or more images of the same scene obtained at different times, from different perspectives, or sensors such as MRI, X-ray and CT. This step is required to facilitate automatic segmentation for tumour detection or to inform further decisions in treatment planning. It is an important and challenging subject which usually involves high storage, computational cost and dealing with distorted and occluded data. The paradigm behind image registration is to find a reasonable transformation so that the template image becomes similar to the so-called given reference image. Through such transformation, information from these images can be compared or combined. This thesis deals with the mathematical modelling of image registration by way of energy minimisation of a functional. We propose a new decomposition model for image registration which combines parametric transformation and non-parametric deformation. The first category of methods is based on a small number of parameters and for the second category the transformation is based on a functional map (or discretely a large number of parameters) with a regularisation term. We choose one cubic B-spline based model and the linear curvature model for the parametric and non-parametric parts respectively where the overall deformation consists of both global and local displacement for effective image registration. Some results for synthetic and real images will be presented to illustrate the effectiveness of the new model in contrast with the individual models. We then propose a novel variational model for image registration which employs Gaussian curvature as a regulariser. The model is motivated by the surface restoration work in geometric processing [21]. An effective numerical solver is provided for the model using an augmented Lagrangian method. Numerical experiments show that the new model outperforms three competing models based on, respectively, the linear curvature [24], the mean curvature [19] and the diffeomorphic demon models [93] in terms of robustness and accuracy. Finally, we present an improved model for joint segmentation and registration based on active contour without edges. The proposed model is motivated by an earlier model [58] and the linear curvature model [24]. Numerical results show that the new model outperforms the existing model for registration and segmentation of one or multiple objects in the image. The proposed model also leads to improved registration results when features exist inside the object.

description: We study the diffusion of epidemics on networks that are partitioned into local communities. The gross structure of hierarchical networks of this kind can be described by a quotient graph. The rationale of this approach is that individuals infect those belonging to the same community with higher probability than individuals in other communities. In community models the nodal infection probability is thus expected to depend mainly on the interaction of a few, large interconnected clusters. In this work, we describe the epidemic process as a continuous-time individual-based susceptible-infected-susceptible (SIS) model using a first-order mean-field approximation. A key feature of our model is that the spectral radius of this smaller quotient graph (which only captures the macroscopic structure of the community network) is all we need to know in order to decide whether the overall healthy-state defines a globally asymptotically stable or an unstable equilibrium. Indeed, the spectral radius is related to the epidemic threshold of the system. Moreover we prove that, above the threshold, another steady-state exists that can be computed using a lower-dimensional dynamical system associated with the evolution of the process on the quotient graph. Our investigations are based on the graph-theoretical notion of equitable partition and of its recent and rather flexible generalization, that of almost equitable partition.

title: An anthropological assessment of Neanderthal behavioural energetics
Creators: name: Shuttleworth, Andy
Publisher: name: University of Liverpool Repository
Year: 2013

description: The debate on Neanderthal social and symbolic capabilities is one of the fundamental issues of Palaeolithic archaeology, with the archaeological record suggesting that Neanderthals did not display the same range and variability of behaviours as anatomically modern humans (AMH). This lack of evidence has often been attributed to the cognitive superiority of AMH over Neanderthals. The reliance on the material record alone, however, neglects a range of non-material behaviours that are arguably of equal importance to understanding the cognitive abilities of this species, but which leave no archaeological traces. This thesis presents an alternative approach to the interpretation of Neanderthal social behaviour that is based on ethnographic modelling drawn from contemporary hunter-gatherers and applied to the archaeological records of Neanderthals and AMH living in Europe during Oxygen Isotope Stage 3 (60-30ka). The aim of this thesis is to highlight Neanderthal behavioural responses to fluctuations in environmental productivity and to compare these to the behaviours of AMH in the earlier Upper Palaeolithic to determine if any significant differences existed between the two species. The thesis employs a range of ethnographic and archaeological data which relate to a range of material and non-material social and symbolic behavioural expressions, such a rites of passage, cooperative hunting, care for the elderly, and prestige hierarchies that are not typically inferred from the archaeological record. The ethnographic record allows for the quantification of such behaviours so that correlations can be made between social expressions (cohesion, control etc) that can then be inferred from the material record. Statistical tests, including General Linear Modelling, were employed to determine the robustness of these correlations. The ethnographic model was applied to the archaeological record of the Upper Palaeolithic prior to its being applied to the Neanderthal record of OIS-3 to determine the suitability of applying it to prehistoric contexts. Results show that both Neanderthals and AMH employed similar behavioural mechanisms for coping with resource stress in relation to social cohesion, though individual expressions varied between the two species depending on their environmental contexts. Analysis suggests that the Neanderthal capacity for spiritual and material expression was hindered by demographic and physiological constraints rather than any differences in cognitive capacity. Finally, analysis shows that Neanderthals employed optimal behavioural capacities throughout the Middle Palaeolithic and were a much more behaviourally variable hominid than previous interpretations of the archaeological record have suggested.
title: US Protestant natalist reception of Old Testament “fruitful verses”: a critique
Creators: name: McKeown, John Patrick
Publisher: name: University of Liverpool Repository
Year: 2013

description: The advocacy of a high birth rate is an ideology called natalism. In the USA since 1985 some Protestants have used Old Testament verses to support natalist arguments. This thesis argues that natalism is inappropriate as a Christian application of Scripture, especially since rich nations’ populations’ total footprint is detrimental to biodiversity and to poor nations’ welfare. The methodology is analysis of natalist writings, investigation of possible historical roots, and then evaluation of natalist interpretation from three perspectives: the ancient Near Eastern OT context, patristic Christian tradition, and contemporary ecological concerns. The analysis and historical investigation consists of two chapters. Chapter 2 considers wider natalism, modern secular and religious varieties, and the cultural context of US Evangelicalism. Through textual analysis of biblical reception in recent natalist writings, it identifies the verses cited and common interpretative arguments. Chapter 3 asks whether this natalism has roots in historic Protestantism. It investigates the claim made by some natalist advocates that Martin Luther in the 16th century expounded similar ideas about fecundity. The evaluation consists of three chapters. Chapter 4 explores the ancient Near Eastern cultural context, and Old Testament ideas about fecundity’s role in God’s project of salvation. Ventures by biblical scholars into contemporary application of the verses in question are critiqued. Chapter 5 considers Augustine’s comments on human fruitfulness in the Bible and his thinking on fecundity. Using ressourcement from this representative of patristic tradition, Augustine’s reception is compared with natalism. Chapter 6 explains an ecological hermeneutic which brings biblical and classic Christian biblical reception into conversation with contemporary concerns. My reception of the verses uses a hermeneutic lens derived from Genesis 1, and gives priority to the contextual issues of biodiversity and the un/sustainability of the ecological footprints of overpopulated rich nations. The thesis is the first to offer systematic analysis of natalist biblical reception, and focuses on the neglected majority of natalists which accepts family planning. It highlights exegetical arguments which are then compared with Luther’s writings, tested against plausible meanings of the fruitful verses, and tested against Augustine and patristic tradition. Previous research on ecologically responsible interpretation of these verses and on Christian thinking about human fecundity and overpopulation is updated and extended.

description: We investigate the perturbative aspects of Rozansky-Witten's 3d $σ$-model using Costello's approach to the Batalin-Vilkovisky (BV) formalism. We show that the BV quantization (in Costello's sense) of the model, which produces a perturbative quantum field theory, can be obtained via the configuration space method of regularization due to Kontsevich and Axelrod-Singer. We also study the factorization algebra structure for quantum observables following Costello-Gwilliam. In particular, we show that the cohomology of local quantum observables on a genus $g$ handle body is given by $H^*(X,(\wedge^*T_X)^{\otimes g})$ (where $X$ is the target manifold), and prove that the partition function reproduces the Rozansky-Witten invariants.

title: Studies of the Wnt/Beta-catenin signalling pathway in chronic myeloid leukaemia
Creators: name: Fowler, Rachael
Publisher: name: University of Liverpool Repository
Year: 2015

description: The Wnt/β-catenin signalling pathway is involved in regulating cellular transcription of numerous target genes in chronic myeloid leukaemia (CML). A previous report using granulocyte-macrophage progenitors (GMPs) showed that elevated levels of unphosphorylated (active) β-catenin, alongside mis-splicing of glycogen synthase kinase 3β (GSK3β), correlated with disease progression. It was of interest to determine if using the more readily available peripheral blood mononuclear cells (MNCs) also showed any correlation with patient outcome when β-catenin and GSK3β were measured in this source material. Further investigation in these cells addressed GSK3β activity regulation, possible regulation of c-Myc degradation by GSK3β, and investigation of Wnt transcription factors in CML. Results indicated that levels of β-catenin (and its phosphorylated variants) could not be used to distinguish patient treatment outcomes using CML MNCs. However the levels of BCR-ABL1 induced β-catenin-Tyr654 phosphorylation showed a significant decrease in patients in blast crisis compared to chronic phase (P=0.012), as did the levels of GSK3β – which demonstrated significantly decreased activity in blast crisis patients via a significant increase in Ser9 phosphorylation and a significant decrease in Tyr216 phosphorylation in blast crisis compared to chronic phase (P=0.026 and

For $N_f=6,7$ flavors, we explicitly compute the Seiberg-Witten curves for 5d Sp(1) gauge theory, and show that these Seiberg-Witten curves agree with already known $E_{7,8}$ results.

description: There is growing evidence that an individual’s personality traits are related to post-concussion symptomatology beyond the acute period after mild traumatic brain injury (mTBI). Few studies, however, have analyzed this impact beyond the personality trait of Neuroticism. We examined the impact of personality traits on post-concussion symptoms (PCS) by measuring the Big Five personality domains and their lower-order aspects in 87 pre-morbidly healthy participants assessed 6–12 weeks post-mTBI (n = 53) or physical trauma (n = 34). As expected, Neuroticism predicted PCS endorsement in both groups. Conscientiousness and Openness/intellect were predictive of lower PCS endorsement, but only in the mTBI group. Withdrawal, one aspect within the Neuroticism domain, independently predicted PCS endorsement in the mTBI group; the remaining Neuroticism aspect, Volatility, did not predict PCS endorsement in either group. These findings suggest that individuals high in Neuroticism are more likely to report PCS following mTBI and that this relationship is driven by susceptibility to depression/anxiety symptoms (Withdrawal aspect) rather than irritability (Volatility aspect). Further, they suggest that the current focus on the relationship between Neuroticism and PCS reporting in individuals with mTBI should be broadened to include other personality domains, such as Conscientiousness and Openness/intellect.

We prove that a ring R is almost Armendariz if and only if n X n upper triangular matrix ring T_{n}(R) is almost Armendariz ring. Similarly, If R is almost Armendariz if and only if R[x] is almost Armendariz. It is observed that every almost Armendariz ring is weak Armendariz but converse need not be true. But, if R is semicommutative ring, then weak Armendariz ring is almost Armendariz ring. Moreover, the class of minimal noncommutative almost Armendariz rings is completely determined, up to isomorphism (minimal means having smallest cardinality).

description: In this paper, we analyzed differences between uncoached, symptom-coached, and test-coached simulators regarding strategies of feigning mild head injuries. Healthy undergraduates (n = 67 in the first study; n = 48 in the second study), randomized into three simulator groups, were assessed with four experimental memory tests. In the first study, tests were administered face-to-face, while in the second study, the procedure was adapted for online testing. Online simulators showed a different approach to testing than face-to-face participants (U tests < 920, p < .05). Nevertheless, both samples favored strategies like memory loss, error making, concentration difficulties, and slow responding. Except for slow responding and concentration difficulties, the favorite strategies correlated with validity indicators. In the first study, test-coached simulators (m = 4.58–5.68, SD = 2.2–3) used strategies less than uncoached participants (m = 5.25–5.88, SD = 2.26–2.84). In the second study, test-coached participants (m = 3.8–5.6, SD = 1.51–2.2) employed strategies less than uncoached (m = 6.21–7.29, SD = 1.25–1.85) and symptom-coached participants (m = 6.14–6.79, SD = 1.69–2.76). Similarities and differences between online and face-to-face assessments are discussed. Recommendations to associate heterogeneous indicators for detecting feigning strategies are issued.
title: A commentary on Statius Thebaid 6. 1-192
Creators: name: Mottram, Philip
Publisher: name: University of Liverpool Repository
Year: 2012

description: The commentary examines the first 192 verses of Thebaid 6, which describe the preparation and events before the funeral of Ophletes/Archemorus. The commentary explores the cultural effect and “affect” of the text. Philological and intertextual issues are discussed throughout. Textual problems are treated where appropriate. The introduction provides an overview of major themes, concepts and contexts. In the commentary itself, discursive notes introduce shorter lemmata that encompass textual, metrical, linguistic and cultural-historical issues as well as literary interpretation. Theb.6.1-24 describes the summoning of competitors to the first games at Nemea, places those games within the tradition of the other Panhellenic games and finishes with the first simile in the book. The commentary discusses the epinician, aetiological and anachronistic features of the language here and introduces the concept of the “hanging simile”. vv. 25-53 describe an “epic” Dawn, detail the lamenting in and around the palace and summarize the consolation speech of Adrastus. The commentary examines how reader expectations are defeated and how Roman and Greek rituals merge at this point. The rhetorical features of consolatio and the ineffectiveness of oratory to console are considered. vv. 54-83 focus is on the funeral couch of Opheltes. The commentary discusses the metapoetic comment in this passage; also the use of ekphrasis and the emotional significance of the gifts placed on the pyre. vv. 84-117 detail the cutting down of the grove for the funeral pyre, following aspects of the traditional topos and finishing on a second simile, the latter anachronistically describing direptio. The commentary draws out the Greek and indigenous Italian elements of this passage and shows how the language foreshadows future conflict. The animated and hyperreal nature of the landscape is explained in the commentary. vv. 118-134 the gods above and below are given equal altars and the funeral procession starts. The commentary discusses the infernal gods in the context of the poem, elucidating Roman and “Oriental”, as well as Greek, motifs. vv.135-192 Eurydice, mother of Opheltes begins a lament but, on seeing Hypsipyle, she turns it into a recriminatory speech. The commentary examines her speech as an intertextual node around which other mothers, distraught and guilty because of a lost child, can be seen. Her speech, language and non-verbal communication are then associated with these intertexts. Focus is also upon how the speech changes in terms of tone, elevation and erratic structure, and illuminates the historical/eternal conflict between birth mother and wet-nurse. The generic relationship between epic narrative and dramatic structures, such as tragedy and mime are made throughout the commentary especially at 25-192.

description: We present an updated model of light and charge yields from nuclear recoils in liquid xenon with a simultaneously constrained parameter set. A global analysis is performed using measurements of electron and photon yields compiled from all available historical data, as well as measurements of the ratio of the two. These data sweep over energies from 1 - 300 keV and external applied electric fields from 0 - 4060 V/cm. The model is constrained by constructing global cost functions and using a gradient descent minimizer, a simulated annealing algorithm, and a Markov Chain Monte Carlo approach to optimize and find confidence intervals on all free parameters in the model. This analysis contrasts with previous work in that we do not unnecessarily exclude data sets nor impose artificially conservative assumptions, do not use spline functions, and reduce the number of parameters used in NEST v0.98. We report our results and the calculated best-fit charge and light yields. These quantities are crucial to understanding the response of liquid xenon detectors in the energy regime important for rare event searches such as the direct detection of dark matter particles.

Another aim was to assess the receptive and expressive abilities of subjects with TBI based on the location of the injury. This is a retrospective observational study including 49 participants with TBI due to war injuries. The Arabic Diagnostic Aphasia Battery (A-DAB-1) was administered to the participants and the Helsinki CT score was computed to quantify brain damage. The results showed that the Helsinki CT score was negatively correlated with the total score of the A-DAB-1 (r = −0.544, p-value < 0.0001). Simple linear regression supported such findings and reflected an inversely proportional relationship between both variables (p-value < 0.0001). When compared with subjects having right hemisphere damage, subjects with left hemisphere and bilateral brain damage performed more poorly on language tasks respectively as follows: A-DAB-1 overall score (92.08-66.08-70.28, p-value = 0.021), Content of descriptive speech (9.57-6.69-7.22, p-value = 0.034), Verbal fluency (6.57-3.54-3.89, p-value = 0.002), Auditory comprehension (9.71-7.54-7.78, p-value = 0.039), Complex auditory commands (9.71-7.65-7.56, p-value = 0.043), Repetition (9.75-7.08-7.61, p-value = 0.036), Naming (9.93-7.15-8.11, p-value = 0.046). Following TBI, CT findings on admission can significantly predict long-term language abilities, with left side lesions inducing poorer outcomes.

description: We investigate the possible presence of active galactic nuclei (AGN) in dwarf galaxies and other nearby galaxies to identify candidates for follow-up confirmation and dynamical mass measurements. We use the Wide-field Infrared Survey Explorer (WISE) All-Sky Release Source Catalog and examine the infrared colours of a sample of dwarf galaxies and other nearby galaxies in order to identify both unobscured and obscured candidate AGN by applying the infrared colour diagnostic. Stellar masses of galaxies are obtained using a combination of three independent methods. Black hole masses are estimated using the bolometric luminosity of the AGN candidates and computed for three cases of the bolometric-to-Eddington luminosity ratio. We identify 303 candidate AGN, of which 276 were subsequently found to have been independently identified as AGN via other methods. The remaining 9% require follow-up observations for confirmation. The activity is detected in galaxies with stellar masses from ~ 10^6 to 10^9 solar masses; assuming the candidates are AGN, the black hole masses are estimated to be ~ 10^3 - 10^6 solar masses, adopting L_bol = 0.1 L_Edd. The black hole masses probed are several orders of magnitude smaller than previously reported for centrally located massive black holes. We examine the stellar mass versus black hole mass relationship in this low galaxy mass regime. We find that it is consistent with the existing relation extending linearly (in log-log space) into the lower mass regime. These findings suggest that CMBH are present in low-mass galaxies and in the Local Universe, and provide new impetus for follow-up dynamical studies of quiescent black holes in local dwarf galaxies.

title: Human-directed dog aggression; a systematic review
Creators: name: Newman, Jenny

description: Human-directed dog aggression is a worldwide issue with major public health and animal welfare implications. Consequences for the target of aggression range from fear and minor injury, to life threatening injury and death, and for the dog impaired freedoms, restricted interactions and ultimately euthanasia. The systematic review undertaken here aimed to identify and assimilate all robust evidence regarding factors that affect the risk of human-directed dog aggression. Such information is vital for the development of sound preventive strategies. Multiple electronic literature databases were interrogated in order to identify all evidence for risk factors of human-directed dog aggression. The search strategy was designed to minimise the risk of publication and language biases, specificity was sacrificed for sensitivity. The threshold for acceptance of evidence was predetermined at a moderate level; any study that provided evidence with a low risk of confounding and bias and a moderate probability that any relationship identified was causal would reach the final review. Appraisal examined methodological quality, study design, selection process, measurement of outcome and exposures, and type and quality of analysis. All stages of appraisal were undertaken blind to the study findings. On assimilating the evidence identified, no robust evidence for any risk factors of human-directed dog aggression was identified. Eight studies provided a moderate level of somewhat conflicting evidence. Amongst those studies appraised as failing to reach the moderate level of acceptable evidence, the majority were excluded as a result of multiple limitations. It is vital that future research is undertaken to a high methodological standard in order that it provides robust evidence for the effect of any risk factor identified.

description: The elemental abundances of symbiotic giants are essential to address the role of chemical composition in the evolution of symbiotic binaries, to map their parent population, and to trace their mass transfer history. However, the number of symbiotic giants with fairly well determined photospheric composition is still insufficient for statistical analyses. This is the third in a series of papers on the chemical composition of symbiotic giants determined from high resolution (R ~ 50000), near-IR spectra. Here we present results for 24 S-type systems. Spectrum synthesis methods employing standard local thermal equilibrium analysis and atmosphere models were used to obtain photospheric abundances of CNO and elements around the iron peak (Fe, Ti, Ni, and Sc). Our analysis reveals metallicities distributed in a wide range from slightly supersolar ([Fe/H] ~ +0.35 dex) to significantly subsolar ([Fe/H] ~ -0.8 dex) but principally with near-solar and slightly subsolar metallicity ([Fe/H] ~ -0.4 to -0.3 dex). The enrichment in 14N isotope, found in all these objects, indicates that the giants have experienced the first dredge-up. This was confirmed in a number of objects by the low 12C/13C ratio (5-23). We found that the relative abundance of [Ti/Fe] is generally large in red symbiotic systems.

title: Young people in coastal resorts: a critical exploration of class, place, governance and safety.

description: This thesis analyses the ways in which young people conceptualise crime, policing, safety and security in their own localities. It draws upon primary empirical research to elicit the experiences and perceptions of young people in two coastal resorts. The methods employed in this research give voice to young people and aim to provide a greater understanding of their lives. An ethnographic study was conducted in two coastal resorts, one in England and one in Wales, and access to young people was facilitated through centre-based youth organisations and outreach work in the communities over a period of twelve months (six months in each locality). The research participants were aged between 10 and 17 years old. In total, 100 qualitative interviews were conducted: 23 semi-structured interviews with young people in the youth organisations and 77 unstructured qualitative interviews with young people ‘on the street’. Additional qualitative data were also generated with young people in the youth organisations through a range of methods including: participant observation; various group work exercises; photographic methods; group discussions and other visual techniques. Additional data of 12 semi-structured interviews were generated with professionals in the field of crime prevention and youth work. The thesis offers a significant contribution to knowledge about the experiences and perceptions of young people in two coastal resorts. The thesis illustrates how socio-economic characteristics of ‘place’ and ‘social class’ profoundly structure and shape young people’s experiences and perceptions. The impact of social class on access and restrictions in public space, leisure pursuits, the formation of youth identities, attachment to place, fear of crime, and young people’s securities and insecurities are all examined. The context for the research, two very different coastal resorts in socio-economic terms, revealed significant differences in how young people are policed in coastal resorts; how youth policy impacts upon their everyday experiences; and how social class is a determining factor that shapes their lives. It also raised a number of questions regarding young people’s safety in local public space. With respect to this, the research explored the main issues of concern for young people within and outside of crime prevention discourses and, in doing so, compared and contrasted the ways in which questions of youth, crime, youth governance, youth victimisation and related issues are expressed and represented in official policy discourses with that of young people’s experiences and perceptions.

description: Under ideal conditions, quantum metrology promises a precision gain over classical techniques scaling quadratically with the number of probe particles. At the same time, no-go results have shown that generic, uncorrelated noise limits the quantum advantage to a constant factor. In frequency estimation scenarios, however, there are exceptions to this rule and, in particular, it has been found that transversal dephasing does allow for a scaling quantum advantage. Yet, it has remained unclear whether such exemptions can be exploited in practical scenarios. Here, we argue that the transversal-noise model applies to the setting of recent magnetometry experiments and show that a scaling advantage can be maintained with one-axis-twisted spin-squeezed states and Ramsey-interferometry-like measurements. This is achieved by exploiting the geometry of the setup that, as we demonstrate, has a strong influence on the achievable quantum enhancement for experimentally feasible parameter settings. When, in addition to the dominant transversal noise, other sources of decoherence are present, the quantum advantage is asymptotically bounded by a constant, but this constant may be significantly improved by exploring the geometry.
