description: A locating-dominating set of a graph $G$ is a dominating set $D$ of $G$ with the additional property that every two distinct vertices outside $D$ have distinct neighbors in $D$; that is, for distinct vertices $u$ and $v$ outside $D$, $N(u) \cap D \ne N(v) \cap D$ where $N(u)$ denotes the open neighborhood of $u$. A graph is twin-free if every two distinct vertices have distinct open and closed neighborhoods. The location-domination number of $G$, denoted $γ_L(G)$, is the minimum cardinality of a locating-dominating set in $G$. It is conjectured [D. Garijo, A. González and A. Márquez. The difference between the metric dimension and the determining number of a graph. Applied Mathematics and Computation 249 (2014), 487--501] that if $G$ is a twin-free graph of order $n$ without isolated vertices, then $γ_L(G)\le \frac{n}{2}$. We prove the general bound $γ_L(G)\le \frac{2n}{3}$, slightly improving over the $\lfloor\frac{2n}{3}\rfloor+1$ bound of Garijo et al. We then provide constructions of graphs reaching the $\frac{n}{2}$ bound, showing that if the conjecture is true, the family of extremal graphs is a very rich one. Moreover, we characterize the trees $G$ that are extremal for this bound. We finally prove the conjecture for split graphs and co-bipartite graphs.

description: La definizione delle emozioni, la loro importanza e il posto che hanno nelle relazioni che intessono con l’arte e la cultura, il loro trattamento scientifico nelle scienze umane e sociali permettono di esplorare da nuove angolazioni il rapporto del pubblico con la cultura. Una parte dell’articolo sarà dedicato alla forma del festival, che si rivela propizia alla costruzione delle emozioni e alla maniera in cui questo terreno del “sensibile” interagisce con i dispositivi che ruotano intorno all’Educazione Artistica e Culturale, nonché con quelle prospettive di ricerca che aprono sullo studio del sensibile. Senza voler minimizzare l’analisi quantitativa, questa comunicazione cercherà di mostrare la maniera in cui l’analisi attraverso le cifre e quella attraverso le emozioni sono più complementari che antitetiche. La sfida è nondimeno quella di sviluppare un metodo attraverso il quale la presa in conto delle emozioni permette una valutazione più fine, considerando le emozioni non degli strumenti, ma degli oggetti di studio e d’azione. Il terreno di studio del nostro intervento è il festival delle “Rencontres trans-musicales” di Rennes.

description: Let $M$ be an arbitrary complex manifold and let $L$ be a Hermitian holomorphic line bundle over $M$. We introduce the Berezin-Toeplitz quantization of the open set of $M$ where the curvature on $L$ is non-degenerate. The quantum spaces are the spectral spaces corresponding to $[0,k^{-N}]$ ($N>1$ fixed), of the Kodaira Laplace operator acting on forms with values in tensor powers $L^k$. We establish the asymptotic expansion of associated Toeplitz operators and their composition as $k\to\infty$ and we define the corresponding star-product. If the Kodaira Laplace operator has a certain spectral gap this method yields quantization by means of harmonic forms. As applications, we obtain the Berezin-Toeplitz quantization for semi-positive and big line bundles.

title: Structural and functional characterization of novel enzymes from targeted probiotic Lactic bacterial strains for the production of new generation prebiotics
Creators: name: Feliciotti, Irene
Publisher: name: University of Reading

description: The human gut microbiome is a complex ecosystem which includes predominantly bacteria, but also protozoa, archaea, eukaryotes, and viruses, that live symbiotically within various sites of the human body. This living microbiome plays a crucial role in human health. However, the gut microbiome equilibrium is delicate, and different strategies to modulate bacterial populations have been proposed. One approach involves the use of prebiotics and probiotics, as supplements, able to alter the microbial composition in the gut and increase its beneficial effects on the host. This project focuses on two Lactobacillus strains already used as a probiotic for their beneficial effects on lipid metabolism. Recent sequencing of specific Lactobacillus plantarum 2830 and Lactobacillus rhamnosus GR1 has revealed potential novel enzymes responsible for beneficial effects on human health. Specifically, this project focuses on three β-galactosidases from L. plantarum (belonging to GH2 and GH42 protein families) and one β-galactosidase from L. rhamnosus (Bgal_LR) belonging to the GH35 protein family. Collectively, the GH family enzymes are responsible for galactooligosaccharide (GOS) synthesis, which can provide prebiotic effects to the host and, consequently, lower cholesterol levels and modulate the gut microflora. In an effort to elucidate the functional role of these lactobacilli enzymes for the production of new GOS products as potential prebiotics, detailed structure-function studies were initiated for these newly identified β-galactosidases. Bioinformatics tools have been utilized to identify important functional and structural domains for these enzymes and X-ray crystallography has been used for their structural characterisation. Subsequently, protein engineering was used to identify specific mutations, for each enzyme of interest, to improve the production of their corresponding novel GOS mixtures. The results obtained from the solved structure of Bgal_LR and the assessment of its corresponding activity profile revealed key residues for successful GOS production. The structure-based protein engineering approach, utilised in this work, highlighted the importance of residues Glu128 and Tyr295 for, respectively, hydrolysis and transgalactosylation. Thus, targeting these and other residues in the active site could further improve the production of a novel GOS mixture. This work has contributed to our understanding of the detailed mechanisms of action of specific lactobacilli enzymes and for the first time has shown that these enzymes can be used in the production of novel GOS.

description: Stock market comovements are examined using cointegration, Granger causality tests and nonlinear approaches in context of mutual information and correlations. Underlying data sets are affected by non-stationarities and trends, we also apply AMF-DFA and AMF-DXA. We find only 170 pair of Stock markets cointegrated, and according to the Granger causality and mutual information, we realize that the strongest relations lies between emerging markets, and between emerging and frontier markets. According to scaling exponent given by AMF-DFA, $h(q=2)>1$, we find that all underlying data sets belong to non-stationary process. According to EMH, only 8 markets are classified in uncorrelated processes at $2σ$ confidence interval. 6 Stock markets belong to anti-correlated class and dominant part of markets has memory in corresponding daily index prices during January 1995 to February 2014. New-Zealand with $H=0.457\pm0.004$ and Jordan with $H=0.602\pm 0.006$ are far from EMH. The nature of cross-correlation exponents based on AMF-DXA is almost multifractal for all pair of Stock markets. The empirical relation, $H_{xy}\le [H_{xx}+H_{yy}]/2$, is confirmed. Mentioned relation for $q>0$ is also satisfied while for $q<0$ there is a deviation from this relation confirming behavior of markets for small fluctuations is affected by contribution of major pair. For larger fluctuations, the cross-correlation contains information from both local and global conditions. Width of singularity spectrum for auto-correlation and cross-correlation are $Δα_{xx}\in [0.304,0.905]$ and $Δα_{xy}\in [0.246,1.178]$, respectively. The wide range of singularity spectrum for cross-correlation confirms that the bilateral relation between Stock markets is more complex. The value of $σ_{DCCA}$ indicates that all pairs of stock market studied in this time interval belong to cross-correlated processes.

title: Essays in empirical corporate finance

description: The aim of my thesis is to apply empirical methods to investigate corporate finance questions. In the first chapter, I investigate an unexplored role of venture capital (VC) investors on innovation: the potential value-add of due-diligence for firms involved in failed VC fundraising campaigns— i.e., startups that do not receive investment from the VC doing due diligence. We show that assignment to due-diligence leads to substantial increases in startup growth within two years of application, even for firms involved in failed fundraising campaigns. This new evidence implies that VCs' role in innovation affects many more firms than existing research has fully recognized, as it goes beyond their value-added effects on the portfolio companies in which they invest. In the second chapter, I collected a novel data set of the local planning applications in London and measure the quality of government by the speed of processing applications. I show causal evidence that the quality of local government can affect the households and firms’ activities in housing markets and borrowing behaviors. The effects arise because the timing of property development is important to households and firms. The delay in planning permission will lead them to abandon the project and change behaviors in housing markets and borrowing. In the third chapter, I study the purchasing behaviors of council governments in England and the impacts on the supplier firms. Due to political motivations, council governments’ purchasing patterns and procurement contract terms with local firms are different from that with nonlocal firms. Consequently, selling more goods and services to the local council government relative to other council governments results in more corporate investment.

description: Nowadays, encryption algorithms are playing efficient role in communication systems and data. Absolutely, making a safe connection is cryptography's duty and this science is handling its tasks by presenting encrypting methods; usually, there are some brilliant indexes for these algorithms which are essential like length and type of secret key's characters, required time and ability of operating system for encryption/decryption action. By increasing key's length, the security of data will rise and breaking the probable of key breaking will decrease. In addition, an ideal cryptography algorithm should be implementable even in poor systems; also, at the sensitive platforms, like financial institutes, time is one of the most important factors for choosing a suitable cryptography method. Despite of being hard to understand and limitation for key's character at the most of the encryption algorithms, in this paper we bring a cryptography algorithm based on odd-even attribute named OEA, which is able to carry any key with no limitation for its character's length and type; in fact, the experimental comparisons show that the OEA algorithm is strongly secured, and this method needs less time for processing than the other traditional ways; in addition, it has an easy understanding process.

description: Im Straßenverkehr existieren unterschiedliche Konzepte zur Identifikation von Fahrertypen, die sich hinsichtlich Fahrverhalten und Einstellung zum Fahren unterscheiden. Im Rahmen der Automatisierung von Fahraufgaben gilt es zu überprüfen, wie diese Konzepte an die Herausforderungen veränderter Mensch-Maschine-Interaktion angepasst werden müssen und ob sich neuartige Fahrertypen identifizieren lassen. Auf Basis bestehender Typisierungen aus der Verkehrspsychologie sowie Erkenntnissen der Automationsforschung werden dazu die Konzepte des „Driving Style“ und „Driving Skill“ weiterentwickelt, um Fahrertypen im Kontext des automatisierten Fahrens zu identifizieren. In einer großzahligen Online-Umfrage wurden drei Fahrertypen identifiziert, die sich insbesondere hinsichtlich ihrer Einstellung zum automatisierten Fahren unterscheiden. In einer experimentellen Studie im Fahrsimulator kann anschließend gezeigt werden, dass diese Fahrertypen die Automation im Fahrzeug jeweils anders erleben und daher differenzierte Ansprüche an diese richten. Insgesamt deuten die Studienergebnisse darauf hin, dass die Akzeptanz des automatisierten Fahrens durch nutzergerechte Technik gefördert werden könnte. Die Ergebnisse dienen dazu, die jeweiligen Fahrertypen, ihre Einstellungen und ihre Nutzungspräferenzen im Kontext des automatisierten Fahrens besser zu verstehen und erste Ansatzpunkte für deren Berücksichtigung in der adaptiven Technikentwicklung zu identifizieren.

description: Experiments often yield non-identically distributed data for statistical analysis. Tests of hypothesis under such set-ups are generally performed using the likelihood ratio test, which is non-robust with respect to outliers and model misspecification. In this paper, we consider the set-up of non-identically but independently distributed observations and develop a general class of test statistics for testing parametric hypothesis based on the density power divergence. The proposed tests have bounded influence functions, are highly robust with respect to data contamination, have high power against contiguous alternatives, and are consistent at any fixed alternative. The methodology is illustrated by the simple and generalized linear regression models with fixed covariates.

description: The theme of ancient Egyptian curses is one which attracts the public’s attention via numerous mainstream films and novels. However, relatively few scholarly publications examine this subject in depth, usually dealing with curses and cursing to varying extents, and usually in relation to a wider context. Although numerous such publications have been consulted,1 only two consider Egyptian curses as their main topic and so are presented here: Morschauser, S. (1991), Threat-Formulae in Ancient Egypt: a Study of the History, Structure and Use of Threats and Curses in Ancient Egypt, Baltimore: Halgo and Nordh, K. (1996), Aspects of Ancient Egyptian Curses and Blessings: Conceptual Background and Transmission, Uppsala: Acta Universitatis Upsaliensis. The study of Greek curses, such as Eidinow, E. (2009), Oracles, Curses and Risks among the Ancient Greeks, Oxford: Oxford University Press, is also relevant here for cross-cultural comparative background as it provides useful comparisons in the themes and structure of the presentation.

description: The cultural crossings between music, new digital media,prison and postcolonial Philippine culture form the basis of Dangerous Mediations, which provides a close, intertextual reading of a contemporary prison performance to question the assumptions behind seemingly familiar, entertaining audiovisual media content. Through the lens of critical cultural studies, and ethno/musicology, I examine the interplay between Michael Jackson’s renowned hit Thriller (1983) and a specific interpretation of this work by a group of 1500 Filipino inmates at the Cebu Provincial Rehabilitation and Detention Centre (2007). Rereading Jackson’s impact on popular music and culture in light of postcolonialism, penology, popular music studies,YouTube theory, and in relation to Philippine culture, I trace the evolution of this contemporary music and dance practice within Cebuano culture, as it is transformed and mediated online. I address the prevalent idea of music as an innately positive power, and through a close reading of this irresistible performance, I deconstruct prevailing (dangerous) stereotypes regarding the ‘inherently musical Filipino.’ Reflecting on how, why, and to what effect popular performance can pollinate across cultures and nations, I demonstrate how audiovisual digital platforms such as YouTube can play an important role in shaping our understanding and experiences of the world we live in. Focusing on the performances made by inmates, by Filipinos, by amateurs, I show that we are able not only to historicise the effects of the disenfranchised, but through a close reading of the intertextual, hybridised mediated performance, we may also gain access to and gradually understand that which might otherwise have remained invisible.

description: In this work we study two types of five-dimensional braneworld models given by sine-Gordon potentials. In both scenarios, the thick brane is generated by a real scalar field coupled to gravity. We focus our investigation on the localization of graviton field and the behaviour of the massive spectrum. In particular, we analyse the localization of massive modes by means of a relative probability method in a Quantum Mechanics context. Initially, considering a scalar field sine-Gordon potential, we find a localized state to the graviton at zero mode. However, when we consider a double sine-Gordon potential, the brane structure is changed allowing the existence of massive resonant states. The new results show how the existence of an internal structure can aid in the emergence of massive resonant modes on the brane.

description: We investigate the $γp \to ϕK^+ Λ$ reaction near threshold within an effective Lagrangian approach and the isobar model. Various nucleon resonances caused by the $π$ and $η$ meson exchanges and background contributions are considered. It is shown that the contribution from the $N^*(1535)$ resonance caused by the $η$ meson exchange plays the predominant role. Hence, this reaction provides a good new platform to study the $N^*(1535)$ resonance. The predicted total cross section and specific features of angular distributions can be tested by future experiments.

description: Die Vermittlung der Lesefähigkeit ist eine zentrale Aufgabe der Volksschule. Sie hat über das Fach Deutsch hinaus in allen Schulfächern wie auch außerschulisch große Bedeutung. Wird zudem berücksichtigt, dass die in den unteren Klassen erworbenen basalen Lesekompetenzen die wesentliche Grundlage und zugleich den limitierenden Faktor für den Aufbau hierarchiehöherer Lesekompetenzen in den oberen Primarklassen darstellen (z.B. Perfetti 1985, Rosebrock et al. 2010, Verhoeven & Van Leeuwe 2008), können die Untersuchung und Förderung der Lesekompetenz am Schulbeginn nicht genug Gewicht erhalten.
Das Forschungsprojekt „Die Entwicklung von Wortschatz und Lesen. Eine Untersuchung auf der Unterstufe“ (EnWoLe)1 ist eben diesem frühen Bereich gewidmet, mit dem Ziel, die gegenseitige Beeinflussung von basalen Lesekompetenzen, den Kontextvariablen phonologische Bewusstheit und schnelles Benennen (von Farben, Buchstaben und Zahlen) sowie Wortschatzkompetenzen im ersten bis dritten Schuljahr zu untersuchen. Sowohl das Lesen als auch der Wortschatz werden in mehrere Teilkompetenzen untergliedert. Im Folgenden werden, nach einer kurzen Einführung ins Thema und der damit verbundenen Klärung der Forschungsfrage, die Ergebnisse der Datenerhebung im ersten Schuljahr vorgestellt.

description: Let s be a special point on a Shimura variety, and x a pre-image of s in a fixed fundamental set of the associated Hermitian symmetric domain. We prove that the height of x is polynomially bounded with respect to the discriminant of the centre of the endomorphism ring of the corresponding Z-Hodge structure. Our bound is the final step needed to complete a proof of the Andre-Oort conjecture under the conjectural lower bounds for the sizes of Galois orbits of special points, using a strategy of Pila and Zannier.

title: Epithelial-mesenchymal transition, translocation of Ca2+ signalling complexes and regulation of migration in pancreatic cancer cells
Creators: name: Okeke, Emmanuel
Publisher: name: University of Liverpool Repository
Year: 2015

description: The high mortality of pancreatic cancer is predominantly caused by tumour metastasis. The formation of metastases is dependent on the co-ordinated processes of epithelial-mesenchymal transition (EMT), cell migration and invasion. The importance of Ca2+ signalling in the formation of metastasis in a number of cancer types has been documented. However, our understanding of the Ca2+ signalling components involved in the metastatic dissemination of pancreatic ductal adenocarcinoma (PDAC, specifically PANC-1) is limited. Inositol 1,4,5-trisphosphate receptors (IP3Rs) and store-operated Ca2+ entry (SOCE) channels are the important Ca2+ signalling mechanisms in this cell type. IP3Rs are Ca2+-releasing channels in the endoplasmic reticulum (ER). After Ca2+ release via IP3Rs, restoring of ER Ca2+ involves SOCE mediated by STIM1, which activates PM Ca2+ channels Orai1 to permit Ca2+ influx. This process of Ca2+ influx takes place in unique structures – ER-PM junctions. The goal of the present study was to determine and characterise the fate of IP3Rs and STIM1-competent ER-PM junctions during EMT and the significance of these Ca2+ signalling mechanisms for PANC-1 cell migration. In the present study, I demonstrated that during EMT, PANC-1 cells undergo a dramatic morphological change from apical-basal polarity to front-rear polarity. In cellular monolayers IP3Rs are juxtaposed to cell-cell contacts and closely co-positioned with markers of the tight and adherens junctions. When individual cells migrate away from their neighbours, IP3Rs and SOCE-competent ER-PM junctions underwent dramatic redistribution from cell-cell contacts to accumulate preferentially at the leading edge of PANC-1 cells, where they are in close apposition with the components of migratory apparatus (e.g. focal adhesions). I further demonstrated that focal adhesions were closely encompassed by IP3Rs, creating potholes in excitable medium in which Ca2+ released through IP3Rs affects the remodelling and turnover of focal adhesions, which in turn is necessary for cell migration. Finally, I demonstrated that the migration of PANC-1 cells was suppressed by inhibition of IP3Rs and SOCE, indicating that these mechanisms are functionally important for migration. Taken together, I successfully demonstrated that Ca2+ signalling complexes concentrate in the leading edge of migrating PANC-1 cells and regulate focal adhesion turnover in order to control cell adhesion dynamics and forward movement of PANC-1 cells.

description: K-line profiles emitted from a warm dense plasma environment are used for diagnostics of Ar droplet plasmas created by high energy laser pulses. We observe temperature gradients within the Ar droplet from cold temperatures of the order of some 10 eV up to higher temperatures of about 170 eV. Non-perturbative wave functions are calculated as well as ionization energies, binding energies and relevant emission energies using a chemical {\it ab initio} code. The plasma screening is considered within a perturbative approach to the Hamiltonian. The plasma effect influences the many-particle system resulting in energy shifts due to electron-ion and electron-electron interaction. With this approach we get a good reproduction of spectral features that are strongly influenced by ionization and excitation processes within the plasma. Comparing with the widely known FLYCHK code, counting for internal degrees of freedom (bound states) and treating pressure ionization within our quantum statistical approach leads to different results for the inferred temperature distribution.
description: K-shell emission spectra are critically dependent on the number of atomic configurations considered. The few lowest lying configurations, as used in this paper, are NOT able to explain the features shown in P. Neumayer's spectra of warm dense matter. Some equations and intermediate results require further explanations not given in this manuscript. For a new paper on the topic see arXiv:1709.08493

Also, another challenge in the field of intelligent systems is the integrated transfer of old systems and their launch based on the Internet of Things. On the other hand, ensuring compatibility and flexibility in integrating the devices with the Internet of Things is essential. In this paper, using the hash chain algorithm, a way to control access, authentication, and storage and retrieval of user information in the Internet of Things is presented that users can be more secure than similar methods without knowing The way and place of storage,in order to transfer their data to IoT storage servers.

description: We discuss the impact of many previously neglected effects of higher dimensional operators when fitting to Electroweak Precision data (EWPD) in the Standard Model Effective Field Theory (SMEFT). We calculate the general case of $2 \rightarrow 2$ fermion scattering in the SMEFT to order $\mathcal{O}(\bar{v}_T^2/Λ^2)$ valid on and off the $Z$ pole, in the massless fermion limit. We demonstrate that previously neglected corrections scale as $Γ_Z M_Z/\bar{v}_T^2$ in the partial widths extracted from measured cross sections at LEPI, compared to the leading effect of dimension six operators in anomalous $Z$ couplings. Further, constraints on leading effects of anomalous $Z$ couplings are also modified by neglected perturbative corrections and dimension eight operators. We perform a minimal EWPD fit to illustrate the size of the error these corrections induce, when bounding leading effects. These considerations relax bounds compared to a naive leading order analysis, and show that constraints that rise above the percent level are subject to substantial theoretical uncertanties. We also argue that renormalization group running global constraints expressed through $χ^2$ functions to a common scale, and then minimizing and performing a global fit of all data allows more consistent constraints to be obtained in the SMEFT.

description: Global climate change adaptation and mitigation calls for the resolution of many challenges. Addressing these challenges requires transformation with the introduction of innovative solutions, which need to be evaluated. GOhydro aspires to be a solution for smart urban agriculture, considering new technologies such as IoT and sensors, applicable on indoor farming and more specifically hydroponics. These technologies are significant potentialities and steps towards sustainably feeding a larger, more urban and richer population. Following the Market Research analysis reported in deliverable D6.1, the present report describes the preliminary business plan for the main GOhydro outcomes. We consider as main marketable product the GOhydro platform, better exploited by a joint venture led by SCiO (providing the ICT platform and infrastructure) and incorporating NCSR-D and nr21 DESIGN for sensor and enclosure design, and Holisun for the development and maintenance of the mobile app accompanying the platform. First, we summarize the main market research findings as produced in the context of the D6.1 deliverable. We proceed to an analysis of the key marketable produce features and the corresponding strategies for managing and marketing the product. Finally, we conclude with a summary of the possible business initiation strategy foreseen in our business plan. The main conclusion is that the business model of GOhydro has potential for profitable operations, provided that a marketing approach can create engagement in the digital media, and expenses are controlled and introduced gradually while sales pick up.
title: Defining stemness of human embryonic stem cells: a systems biology approach
Creators: name: Mournetas, Virginie
Publisher: name: University of Liverpool Repository

description: Human embryonic stem cells (hESCs) are undifferentiated cells arising from the inner cell mass of the blastocyst, which are able to self-renew or differentiate in vitro into specialised cell types. These pluripotent cells are a powerful tool to study human embryonic development and have great potential in the field of regenerative medicine. Human ESC pluripotency is governed by an intrinsic transcriptional network composed of the three well-known transcription factors OCT4, SOX2 and NANOG, whereas the role of extrinsic cell/microenvironment interactions in the maintenance of hESC stemness has been neglected to some extent. The aim of this work was to develop a systems biology approach oriented on these extrinsic factors and their links with the transcriptional network, in order to uncover some of the fundamental mechanisms underlying the stemness state. The thesis is divided into two complementary approaches: a top-down in silico study and a bottom-up in vitro study. The top-down in silico approach consists of a meta-analysis of hESC transcriptional data, leading to the construction of a hESC transcriptome. These mRNA data served as proxy for proteins in a protein-protein interaction database to build a hESC interactome. This interactome (or protein-protein interaction network) was structurally defined to identify the likely cell surface and extracellular proteins regulating hESC stemness by revealing the ’module organiser’ or hub proteins and the ’module connector’ or bottleneck proteins, along with the extracellular/transcriptional links. The bottom-up in vitro approach was the study of five of the previously identified cell surface/extracellular proteins in hESC fate decision. These candidates, together with OCT4, were stably knocked down using short hairpin (sh)RNAs and lentiviruses. The optimisation of the shRNA lentivirus production led to the development of a method for the direct quantification of these lentiviral particles. The effects of shRNA-mediated knockdown on hESC phenotype were investigated by assessing cell morphology and by determining the expression levels of the following groups of mRNAs: candidate stemness mRNAs, pluripotency mRNAs, as well as trophectoderm, endoderm, mesoderm and ectoderm mRNAs. We found that the candidates could modulate each other’s expression and appeared to regulate hESC commitment into different lineages. Furthermore, the expression levels of some of the candidates were regulated by OCT4. Taken together, these results suggest that by using the novel in silico approach developed during this project, it is possible to identify new stemness factors that could potentially have a role in either maintaining hESC self-renewal or in regulating lineage specification.

description: We study the quark-antiquark scattering phase shift and meson spectral function in the pion superfluid described by the Nambu--Jona-Lasinio model. The meson mixing in the pion superfluid changes dramatically the full scattering phase shift and spreads strongly the spectral function of some of the collective modes.

description: This presentation was recorded in September 2022 for the BioSciences Education Summit, hosted by Cardiff University. The slides are available as a downloadable file and the recording of the presentation is available to view here. In this 15-minute long presentation I summarise the impact that the COVID-19 pandemic has had on student wellbeing and the consequences of this for skills seen in Higher Education students, such as self-efficacy, learner agency and resilience. I then highlight some of the approaches that we have taken at the University of East Anglia to help support students as they navigate through the transition in to university during these current turbulent times.

description: The International Terrestrial Reference System is built upon multiple geodetic techniques; Satellite Laser Ranging (SLR), Very Long Baseline Interferometry (VLBI), Doppler Orbitography and Radiopositioning Integrated by satellite (DORIS), and Global Navigation Satellite Systems (GNSS). At locations where these techniques are co-located, it is vital to determine and understand the vectors between the reference points of each technique. These vectors are determined by local tie surveys conducted terrestrially with various procedures and geodetic instruments. The reference points should be collected and properly aligned to a global reference frame in order to produce relative and absolute coordinates. The IERS/IAG Joint Working Group on Site Survey and Co-location works to encourage consistent field practice, terminology, and documentation throughout the community, with a continued eye on the future of tie surveys. This update discusses current membership, recent activities, goals moving forward, challenges faced, and opportunities for improvement to the overall combination of space techniques.
Cosmological constraints from the redshift dependence of the Alcock-Paczynski test: galaxy density gradient field

description: We propose a method based on the redshift dependence of the Alcock-Paczynski (AP) test to measure the expansion history of the Universe. It uses the isotropy of the galaxy density gradient field to constrain cosmological parameters. If the density parameter $Ω_m$ or the dark energy equation of state $w$ are incorrectly chosen, the gradient field appears to be anisotropic with the degree of anisotropy varying with redshift. We use this effect to constrain the cosmological parameters governing the expansion history of the Universe. Although redshift-space distortions (RSD) induced by galaxy peculiar velocities also produce anisotropies in the gradient field, these effects are close to uniform in magnitude over a large range of redshift. This makes the redshift variation of the gradient field anisotropy relatively insensitive to the RSD. By testing the method on mock surveys drawn from the Horizon Run 3 cosmological N-body simulations, we demonstrate that the cosmological parameters can be estimated without bias. Our method is complementary to the baryon acoustic oscillation or topology methods as it depends on $D_AH$, the product of the angular diameter distance and the Hubble parameter.

description: The increasing polarization of online political discourse calls for computational tools that automatically detect and monitor ideological divides in social media. We introduce a minimally supervised method that leverages the network structure of online discussion forums, specifically Reddit, to detect polarized concepts. We model polarization along the dimensions of salience and framing, drawing upon insights from moral psychology. Our architecture combines graph neural networks with structured sparsity learning and results in representations for concepts and subreddits that capture temporal ideological dynamics such as right-wing and left-wing radicalization.

title: Development and characterisation of antiretroviral drugs encapsulated in polymer stabilised oil-in-water nanoemulsions

description: HIV continues to be a global healthcare challenge, with estimates suggesting there are currently 35.5 million infected people globally. To date, there have been an estimated 36 million HIV/AIDS related deaths worldwide. The story is changing however, with the advent of Highly Active Antiretroviral Therapies (HAART), allowing patients to live to normal life expectancies and with increasingly better quality of life. This, coupled with the fact that there has been a 40-fold increase in the number of people with access to antiretroviral therapy, has led to a 29% reduction in AIDS related deaths since 2005. Despite this encouraging data, there are still numerous limitations of antiviral therapy, including poor bioavailability, poor patient adherence, and emerging resistance. It is hoped that nanomedicine may offer a route to alleviating some of these issues by achieving an equal therapeutic concentration of drug but with a lower dose. The aims of this thesis were to develop a novel nanoemulsion based formulation of EFV and LPV and to assess the suitability of this formulation as dosage form. Nanoemulsions can be stabilised by surfactants, but often this can have unwanted safety profiles. Stabilisation can also be achieved using amphiphillic polymers that can be synthesised using biocompatible monomers like ethylene glycol. Chapter 2 demonstrates the synthesis of Ethylene Glycol based polymers using both conventional free radical and Atom Transfer Radical Polymerisation techniques. Nanoemulsions have previously been shown in the literature to increase the bioavailability of poorly water-soluble drugs, Chapter 3 shows the development and optimisation of an Oil-in-Water nanoemulsions. The data showed that nanoemulsions synthesised with volatile cosolvents were able to achieve sub 300 nm diameters and have good long-term stability. Increasing the accumulation and permeation of a poorly water-soluble compound should lead to improvements in bioavailability. Chapter 4 shows that the optimal nanoemulsion had comparable accumulation to aqueous solutions and superior apparent permeability cross Caco-2 cell monolayers. The antiviral activity was equipotent to the aqueous solution, as shown in Chapter 5. This confirms that nanoemulsion did not prevent the API from reaching its sight of action. Finally, all new formulations have the potential for detrimental side effects and immunological responses. It is therefore necessary to conduct pre clinical studies to predict such occurrences. Chapter 6 details the lack of immunological response seen in nanoemulsions, but highlights potential interactions with coagulation. In conclusion, this study has found that polymer stabilised oil-in-water nanoemulsions based on Castor oil have promising safety and pharmacological profiles. Further in vivo and studies are now warranted in order to further predict the suitability of nanoemulsions in man.
