description: Mass accretion is the key factor for evolution of galaxies. It can occur through secular evolution, when gas in the outer parts is driven inwards by dynamical instabilities, such as spirals or bars. This secular evolution proceeds very slowly when spontaneous, and can be accelerated when triggered by companions. Accretion can also occur directly through merging of small companions, or more violent interaction and coalescence. We discuss the relative importance of both processes, their time-scale and frequency along a Hubble time. Signatures of both processes can be found in the Milky Way. It is however likely that our Galaxy had already gathered the bulk of its mass about 8-10 Gyr ago, as is expected in hierarchical galaxy formation scenarios.

description: We investigate the possibility that the matter of the universe has a significant component (the quintessence component) determined by the equation of state $p=wρ$, with $w<0$. Here, we find conditions under which a closed model may look like a flat Friedmann-Robertson-Walker universe at low redshift. We study this problem in Einstein's general relativity and Brans-Dicke theories. In both cases we obtain explicit expressions for the quintessence scalar potential $V(Q)$, and the angular size as a function of the redshift.

description: We have used HST/FOS to study faint UV stars in the core of the nearby globular cluster NGC 6397. We confirm the presence of a 4th cataclysmic variable (CV) in NGC 6397 (CV 4), and we use the photometry of Cool et al. (1998) to present evidence that CVs 1--4 all have faint disks and probably low accretion rates. By combining these results with new UV spectra of CV 1 and the published spectra of Grindlay et al. (1995) we present new evidence that CVs 1--3 may be DQ Her systems, and we show that CV 4 may either be a dwarf nova or another magnetic system. Another possibility is that the CVs could be old novae in hibernation between nova eruptions. We also present the first spectrum of a member of a new class of UV bright stars in NGC 6397. These faint, hot stars do not vary, unlike the CVs, and are thus denoted as ``non-flickerers'' (NFs). Like the CVs, their spatial concentration is strongly concentrated toward the cluster center. Using stellar atmosphere models we have determined log g = 6.25, and T_eff = 17,500 K for this NF. Using these line parameters and the luminosity of the NF we show that the NF spectrum is consistent with a helium WD having a mass of ~0.25 solar masses and an age between 0.1 and 0.5 Gyr (depending on the models used). The NF spectrum appears to be significantly Doppler shifted from the expected wavelength, suggesting the presence of a dark, massive companion, probably a carbon-oxygen WD.

description: The ROSAT Bright Survey (RBS) aims to completely optically identify the more than 2000 brightest sources detected in the ROSAT all-sky survey at galactic latitudes |b| > 30 degr (excluding LMC, SMC, Virgo cluster). This paper presents a subsample of 66 bright point-like ROSAT survey sources with almost hard PSPC spectra, the hardness ratio HR1 is > 0.5 for most of the sources. The subsample could be nearly completely identified by low-resolution optical spectroscopy with the following breakdown into object classes: 31 Seyfert galaxies, 22 BL Lac candidates, 5 clusters of galaxies 1 cataclysmic variable, and 5 bright stars. Only one object remained unidentified and one X-ray source was a spurious detect ion. The redshift distribution peaks around 0.06 for the Seyferts and around 0.13 for the BL Lac candidates. Observations with medium spectral resolution were obtained for most of the new S eyfert galaxies. A large fraction (20 objects) are type 1 Seyfert galaxies, the other fraction includes Seyfert galaxies of type 1.5 - 1.8 (5 objects), two LINERs, and 4 possible narrow-line Seyfert 1 galaxies (NLS1). About one third of the new Seyfert's have nearby companion galaxies displaying either emission or absorption lines at the same redshift. Among them are a couple of systems showing direct morphological evidence for interaction. The large fraction of interacting galaxies among our sample suggests a scenario where interaction is the main trigger of AGN activity.

description: We present a magnetic stripping model for AM Her type objects. Our model is based on an equilibrium condition between ram pressure and magnetic pressure in a stiff dipolar magnetic field. We investigate the detailed geometry of the stripping process, most of which can be tackled analytically. By involving additional numerical calculations, the model allows the prediction of phase-resolved spectra and Doppler tomograms. The emission line features from the companion star, the horizontal stream and the accretion curtain are identified with the emission line components found by Gaussian fitting to observational data of HU Aqr in its high accretion state. Given the simplicity of the model, its agreement with the observation is remarkably good and enables and radii, total mass accretion rate, bulk temperature, and coupling density.

Network-aware big data processing
Creators: name: Rupprecht, Lukas
Publisher: name: Imperial College London
Year: 2017

description: The scale-out approach of modern data-parallel frameworks such as Apache Flink or Apache Spark has enabled them to deal with large amounts of data. These applications are often deployed in large-scale data centres with many resources. However, as deployments and data continue to grow, more network communication is incurred during a data processing query. At the same time, data centre networks (DCNs) are becoming increasingly more complex in terms of the physical network topology, the variety of applications that are sharing the network, and the different requirements of these applications on the network. The high complexity of DCNs combined with the increased traffic demands of applications has made the network a bottleneck for query performance. In this thesis, we explore ways of making data-parallel frameworks network-aware, i.e. we combine specific knowledge about the application and the physical network to reduce query completion times. We identify three main types of traffic that occur during query processing and add network-awareness to each of them to optimise network usage. 1) Traffic reduction for aggregatable traffic exploits the physical network topology and the associativity and commutativity of aggregation queries to reduce traffic as early as possible. In-network aggregation trees utilise existing networking hardware and the tree topology of DCNs to partially aggregate and thereby reduce data as it flows through the network. 2) Traffic balancing for non-aggregatable traffic monitors the network throughput of an application and uses knowledge about the query to optimise the overall network utilisation. By dynamically changing the destinations of parts of the transferred data, network hotspots, which can occur when many applications share the network, can be avoided. 3) Traffic elimination for storage traffic gives control over data placement to the application instead of the distributed storage system. This allows the application to optimise where data is stored across the cluster based on application properties and thereby eliminate unnecessary network traffic.

Contributing factors and clinical relevance of early arrhythmia recurrence and electrical reconnection of the pulmonary veins following pulmonary vein isolation for atrial fibrillation
Creators: name: Das, Moloy
Publisher: name: Imperial College London
Year: 2016

description: Pulmonary vein isolation (PVI) is the cornerstone of ablation for paroxysmal atrial fibrillation (AF). However, success rates from AF ablation are not as high as would be hoped and this body of work focussed on improving outcomes from this procedure. Late PV reconnection following PVI is very common and is strongly associated with atrial tachyarrhythmia (AT) recurrence. The primary study of this work involved a randomised controlled trial comparing standard care with a strategy of early repeat electrophysiology study, irrespective of symptoms, to assess for and treat PV reconnection. Patients were followed-up for 12 months with daily ECG monitoring using a portable monitor. This study demonstrated a reduction in AT recurrence and burden and an improvement in quality-of-life in the repeat study group. At present, a 3-month blanking period following PVI is recommended, during which AT recurrences are not deemed indicative of procedure failure. In a secondary study, the relationship between episodes of AT recorded within this 3-month blanking period and PV reconnection was studied. Early recurrence beyond 4 weeks after PVI was associated with PV reconnection, whereas recurrence within the first 4 weeks was not. Force-Time Integral is a commonly-used ablation lesion quality marker but has limitations. Ablation Index is a novel marker incorporating power along with contact force and time in a weighted formula. In a further study, the relationship between Ablation Index and late PV reconnection was examined. Reconnected segments had significantly lower minimum Ablation Index values than non-reconnected segments, and higher values were required to avoid reconnection in anterior/roof segments compared to posterior/inferior segments. In the final part of the work, the relationship between sites of acute PV reconnection that underwent re-ablation and sites of late reconnection was studied, as the effectiveness of such re-ablation is unclear. No difference was found in the rates of late reconnection between areas with and without acute reconnection. Taken together, the findings from these studies provide insights into the potential success rates that can be achieved from durable PVI in patients with paroxysmal AF, and techniques that may help to achieve this. Furthermore, assessment for early recurrence may allow better identification of those patients at higher risk of later recurrence.

description: Objective: Evaluate a method for the estimation of the nocturnal systolic blood pressure (SBP) dip from 24-hour blood pressure trends using a wrist-worn photoplethysmography (PPG) sensor and a deep neural network in free-living individuals, comparing the deep neural network to traditional machine learning and non-machine learning baselines. Approach: A wrist-worn PPG sensor was worn by 106 healthy individuals for 226 days during which 5111 reference values for blood pressure (BP) were obtained with a 24-hour ambulatory BP monitor and matched with the PPG sensor data. Features based on heart rate variability and pulse morphology were extracted from the PPG waveforms. Long- and short term memory (LSTM) networks, dense networks, random forests and linear regression models were trained and evaluated in their capability of tracking trends in BP, as well as the estimation of the SBP dip. Main results: Best performance for estimating the SBP dip were obtained with a deep LSTM neural network with a root mean squared error (RMSE) of 3.12$\pm$2.20 $Δ$mmHg and a correlation of 0.69 $(p=3*10^{-5})$. This dip was derived from trend estimates of BP which had an RMSE of 8.22$\pm$1.49 mmHg for systolic and 6.55$\pm$1.39 mmHg for diastolic BP (DBP). While other models had similar performance for the tracking of relative BP, they did not perform as well as the LSTM for the SBP dip. Significance: The work provides first evidence for the unobtrusive estimation of the nocturnal SBP dip, a highly prognostic clinical parameter. It is also the first to evaluate unobtrusive BP measurement in a large data set of unconstrained 24-hour measurements in free-living individuals and provides evidence for the utility of LSTM models in this domain.

description: Deep radio observations at 5 and 8 GHz are presented of a complete sample of 11 radio galaxies with redshifts 0.85 < z < 1.5, selected from the 6C sample of Eales. The radio data, taken using the VLA in A, B and C array configurations, provide a best angular resolution of 0.25'' and reach an rms noise level of order 20 microJy. Radio core candidates are detected in 8 of the 11 sources. 9 of the 11 sources display deviations from `standard double radio source' morphologies, with multiple hotspots or a hotspot withdrawn from the leading edge of the radio emission. The sources are typically polarised at the 5 to 15% level. The mean rotation measures of the individual lobes are less than 50 rad/m^2 but strong asymmetries between the two lobes indicate that the Faraday rotation does not have a Milky Way origin; rather, the distant 6C radio sources lie in a relatively dense clumpy environment. The sources are compared with the more radio powerful distant 3CR radio galaxies and with low redshift sources. The ratio of core to extended radio flux is almost independent of the radio source size and only weakly inversely correlated with the total radio power. This indicates that the high radio luminosity of the most powerful radio sources must originate in the AGN, in contrast to the suggestion that they are so luminous only due to confinement by a dense surrounding environment. Environmental effects play a secondary role. (Abridged)

description: Spatial Reuse (SR) has recently gained attention to maximize the performance of IEEE 802.11 Wireless Local Area Networks (WLANs). Decentralized mechanisms are expected to be key in the development of SR solutions for next-generation WLANs, since many deployments are characterized by being uncoordinated by nature. However, the potential of decentralized mechanisms is limited by the significant lack of knowledge with respect to the overall wireless environment. To shed some light on this subject, we show the main considerations and possibilities of applying online learning to address the SR problem in uncoordinated WLANs. In particular, we provide a solution based on Multi-Armed Bandits (MABs) whereby independent WLANs dynamically adjust their frequency channel, transmit power and sensitivity threshold. To that purpose, we provide two different strategies, which refer to selfish and environment-aware learning. While the former stands for pure individual behavior, the second one considers the performance experienced by surrounding networks, thus taking into account the impact of individual actions on the environment. Through these two strategies we delve into practical issues of applying MABs in wireless networks, such as convergence guarantees or adversarial effects. Our simulation results illustrate the potential of the proposed solutions for enabling SR in future WLANs. We show that substantial improvements on network performance can be achieved regarding throughput and fairness.

description: The comprehensive knowledge of fundamental parameters of single stars is the basis of the modelling of star clusters and galaxies. Most fundamental stellar parameters of the individual components in SB2 eclipsing binaries are known with very high accuracy. Unfortunately, while masses and radii are well determined, the temperatures strongly depend on photometric calibrations. In the present work, we have used an empirically-calibrated grid of theoretical stellar spectra (BaSeL models) for simultaneously deriving homogeneous effective temperatures and metallicities from observed data. For this purpose, we have selected 20 binary systems (40 stars) for which we have uvby Stromgren photometry with estimated errors (see Lastennet et al., astro-ph/9811103, for details).

SVD-based factored-form Cubature Kalman Filtering for continuous-time stochastic systems with discrete measurements

Publisher: name: arXiv
Year: 2024
Subjects: subject: Optimization and Control (math.OC)

description: In this paper, a singular value decomposition (SVD) approach is developed for implementing the cubature Kalman filter. The discussed estimator is one of the most popular and widely used method for solving nonlinear Bayesian filtering problem in practice. To improve its numerical stability (with respect to roundoff errors) and practical reliability of computations, the SVD-based methodology recently proposed for the classical Kalman filter is generalized on the nonlinear filtering problem. More precisely, we suggest the SVD-based solution for the continuous-discrete cubature Kalman filter and design two estimators: (i) the filter based on the traditionally used Euler-Maruyama discretization scheme; (ii) the estimator based on advanced Itô-Taylor expansion for discretizing the underlying stochastic differential equations. Both estimators are formulated in terms of SVD factors of the filter error covariance matrix and belong to the class of stable factored-form (square-root) algorithms. The new methods are tested on a radar tracking problem.
A Model for the Outer Rings of SN 1987A

Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: I propose a model for the formation of the two outer rings of SN 1987A. The main new ingredient is a short-lived, few times 10 years, intermediate wind, of velocity of about 100 km/s and total mass of about 10^{-3} Mo - few times 10^{-2} Mo\odot which is concentrated near the equatorial plane. This intermediate wind was formed during the few orbital periods when a binary companion entered the envelope of the progenitor of SN 1987a, when the latter was a red supergiant. The intermediate wind formed a hollowed torus with a horseshoe-shaped cross section. The inner regions at the ends of the horseshoe torus are the two outer rings of SN 1987A. The other regions of the torus were cleaned by the fast wind blown after the progenitor turns into a blue giant. The proposed scenario accounts for: (i) slow motion of the outer rings; (ii) the high density contrast of the outer rings to their surroundings; (iii) the presence of only two outer rings; (iv) the displacement of the rings relative to the central star; (v) the fact that no planetary nebulae have been observed to have a single pair of outer rings.

description: Abstract: Polyploidy is present in many cancer types and is increasingly recognized as an important factor in promoting chromosomal instability, genome evolution, and heterogeneity in cancer cells. However, the mechanisms that trigger polyploidy in cancer cells are largely unknown. In this study, we investigated the origin of polyploidy in esophageal adenocarcinoma (EAC), a highly heterogenous cancer, using a combination of genomics and cell biology approaches in EAC cell lines, organoids, and tumors. We found the EAC cells and organoids present specific mitotic defects consistent with problems in the attachment of chromosomes to the microtubules of the mitotic spindle. Time-lapse analyses confirmed that EAC cells have problems in congressing and aligning their chromosomes, which can ultimately culminate in mitotic slippage and polyploidy. Furthermore, whole-genome sequencing, RNA-seq, and quantitative immunofluorescence analyses revealed alterations in the copy number, expression, and cellular distribution of several proteins known to be involved in the mechanics and regulation of chromosome dynamics during mitosis. Together, these results provide evidence that an imbalance in the amount of proteins implicated in the attachment of chromosomes to spindle microtubules is the molecular mechanism underlying mitotic slippage in EAC. Our findings that the likely origin of polyploidy in EAC is mitotic failure caused by problems in chromosomal attachments not only improves our understanding of cancer evolution and diversification, but may also aid in the classification and treatment of EAC and possibly other highly heterogeneous cancers.

description: With the help of a generalization of the Fermat principle in general relativity, we show that chains in CR geometry are geodesics of a certain Kropina metric constructed from the CR structure. We study the projective equivalence of Kropina metrics and show that if the kernel distributions of the corresponding 1-forms are non-integrable then two projectively equivalent metrics are trivially projectively equivalent. As an application, we show that sufficiently many chains determine the CR structure up to conjugacy, generalizing and reproving the main result of [J.-H. Cheng, 1988]. The correspondence between geodesics of the Kropina metric and chains allows us to use the methods of metric geometry and the calculus of variations to study chains. We use these methods to re-prove the result of [H. Jacobowitz, 1985] that locally any two points of a strictly pseudoconvex CR manifolds can be joined by a chain. Finally, we generalize this result to the global setting by showing that any two points of a connected compact strictly pseudoconvex CR manifold which admits a pseudo-Einstein contact form with positive Tanaka-Webster scalar curvature can be joined by a chain.

description: This study examines the patterns, tendencies, and physical severity of spouse abuse in military families. The demographic makeup of military families in many ways parallels that of violent families in the civilian community. Therefore, this study will determine if certain variables will be similarly correlated in cases of wife abuse within military families as they are in civilian families. Although a significant amount of research has been conducted on spouse abuse in the last thirty years, family violence within military families has been virtually ignored. This study utilizes secondary data provided by the Navy Family Advocacy Central Registry located in Millington, Tennessee, and examines how age, pay grade, gender, substance abuse, and having a military spouse affects the severity of physical abuse experienced. Analyses reveals that pay grade and sex are associated with levels of physical violence. More specifically, the majority of spouse abuse occurred among personnel in pay grade E-4 and below, in both the mild and moderate/severe categories. Additionally, men commit more severe abuse than do women.

description: The construction of a meaningful graph topology plays a crucial role in the effective representation, processing, analysis and visualization of structured data. When a natural choice of the graph is not readily available from the data sets, it is thus desirable to infer or learn a graph topology from the data. In this tutorial overview, we survey solutions to the problem of graph learning, including classical viewpoints from statistics and physics, and more recent approaches that adopt a graph signal processing (GSP) perspective. We further emphasize the conceptual similarities and differences between classical and GSP-based graph inference methods, and highlight the potential advantage of the latter in a number of theoretical and practical scenarios. We conclude with several open issues and challenges that are keys to the design of future signal processing and machine learning algorithms for learning graphs from data.

description: Abstract: Retrospective studies have shown artificial intelligence (AI) algorithms can match as well as enhance radiologist’s performance in breast screening. These tools can facilitate tasks not feasible by humans such as the automatic triage of patients and prediction of treatment outcomes. Breast imaging faces growing pressure with the exponential growth in imaging requests and a predicted reduced workforce to provide reports. Solutions to alleviate these pressures are being sought with an increasing interest in the adoption of AI to improve workflow efficiency as well as patient outcomes. Vast quantities of data are needed to test and monitor AI algorithms before and after their incorporation into healthcare systems. Availability of data is currently limited, although strategies are being devised to harness the data that already exists within healthcare institutions. Challenges that underpin the realisation of AI into everyday breast imaging cannot be underestimated and the provision of guidance from national agencies to tackle these challenges, taking into account views from a societal, industrial and healthcare prospective is essential. This review provides background on the evaluation and use of AI in breast imaging in addition to exploring key ethical, technical, legal and regulatory challenges that have been identified so far.

description: In mathematical neuroscience, a special interest is paid to a working memory mechanism in the neural tissue modeled by the Dynamic Neural Field (DNF) in the presence of model uncertainties. The working memory facility implies that the neurons' activity remains self-sustained after the external stimulus removal due to the recurrent interactions in the networks and allows the system to cope with missing sensors' information. In our previous works, we have developed two reconstruction methods of the neural membrane potential from {\it incomplete} data available from the sensors. The methods are derived within the Extended Kalman filtering approach by using the Euler-Maruyama method and the Itô-Taylor expansion of order 1.5. It was shown that the Itô-Taylor EKF-based restoration process is more accurate than the Euler-Maruyama-based alternative. It improves the membrane potential reconstruction quality in case of incomplete sensors information. The aim of this paper is to investigate their pattern recognition facilities, i.e. the quality of the pattern formation reconstruction in case of model uncertainties and incomplete information. The numerical experiments are provided for an example of the stochastic DNF with multiple active zones arisen in a neural tissue.

Early time perturbations behaviour in scalar field cosmologies

Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)

description: We consider the problem of the initial conditions and behaviour of the perturbations in scalar field cosmology with general potential. We use the general definition of adiabatic and isocurvature conditions to set the appropriate initial values for the perturbation in the scalar field and in the ordinary matter and radiation components. In both the cases of initial adiabaticity and isocurvature, we solve the Einstein and fluid equation at early times and on superhorizon scales to find the initial behaviour of the relevant quantities. In particular, in the isocurvature case, we consider models in which the initial perturbation arises from the matter as well as from the scalar field itself, provided that the initial value of the gauge invariant curvature is zero. We extend the standard code to include all these cases, and we show some results concerning the power spectrum of the cosmic microwave background temperature and polarization anisotropies. In particular, it turns out that the acoustic peaks follow opposite behaviours in the adiabatic and isocurvature regimes: in the first case their amplitude is higher than in the corresponding pure cold dark matter model, while they make the opposite thing for pure isocurvature initial perturbations.

Temperature Anisotropies and Distortions Induced by Hot Intracluster Gas on the Cosmic Microwave Background

description: The power spectrum of temperature anisotropies induced by hot intracluster gas on the cosmic background radiation is calculated. For low multipoles it remains constant while at multipoles above $l>2000$ it is exponentially damped. The shape of the radiation power spectrum is almost independent of the average intracluster gas density profile, gas evolution history or clusters virial radii; but the amplitude depends strongly on those parameters and could be as large as 20% that of intrinsic contribution. The exact value depends on the global properties of the cluster population and the evolution of the intracluster gas. The distortion on the Cosmic Microwave Background black body spectra varies in a similar manner. The ratio of the temperature anisotropy to the mean Comptonization parameters is shown to be almost independent of the cluster model and, in first approximation, depends only on the number density of clusters.

Genomic landscape of uveal melanoma
Creators: name: Anbunathan, Hima
Publisher: name: Imperial College London
Year: 2017

description: Uveal melanoma (UM) is the most common cancer of the adult eye which can manifest as a highly aggressive form approximately half of the time. Here a comprehensive landscape of genetic alterations in UMs is described. It was identified by integrating copy number alterations (CNAs), and transcriptomic and whole exome sequencing data from 207 primary UMs. Focal copy number analysis with the GISTIC algorithm refined the boundaries of chromosomal segments with chromosomal gains or losses and candidate cancer genes within these segments were identified. Chromosome 8q24.3 was the region most frequently amplified in UMs, being detected in 72% of tumours. A comparison of focal copy gains and losses with that described by a pan-cancer study revealed Plectin 1 as a candidate gene within the 8q24.3 amplicon. Integration of copy number and transcriptomic data also revealed enrichment of genes within pathways leading to activation of NF-kappa B, WNT signaling and RNA splicing. Using a complementary bioinformatics approach, additional novel mutations in known dominant UM driver genes (GNAQ, GNA11, BAP1, SF3B1, EIFIAX and CYSLTR2) were identified and an accurate estimate of the frequencies of mutations in each gene were obtained. Finally, integration of data obtained from CNAs with mutational and transcriptome data reveled homozygous deletions, protein damaging mutations and gene fusions that targeted chromatin modifiers, and specifically genes encoding components of the human SWItch/Sucrose NonFermentable (SWI/SNF) chromatin remodeling complex. Genes from the BAF complex (ARID1A and ARID1B) and the PBAF complex (PHF10) were subjected to functional loss through CNAs, gene fusions and mutations. Two of these chromatin modifiers (ARID1B and PHF10) map to chromosome 6q whose loss is associated with metastasis in a subset of UMs, and an ARID1B fusion is found in a tumour with a BAP1 mutation that subsequently underwent metastasis. In conclusion, this study provides a comprehensive overview of the landscape of genomic alterations in UM, identifying candidate genes in regions of CNAs and providing further insights into the altered pathways of tumour development and progression.
Supergravity as yang-mills squared
Creators: name: Zoccali, Michele
Publisher: name: Imperial College London
Year: 2018

description: This thesis is concerned with the study of various aspects of the Yang-Mills Squared construction, which aims at furthering our understanding of the provocative idea that gravity may be regarded, in some sense, as the "square" of gauge theory. By assuming a convolutive tensor product and introducing a bi-adjoint scalar fi eld as one of the factors, the Yang-Mills Squared formalism describes a purely field-theoretic realisation of this correspondence: the content as well as the global U-duality symmetries of a wide variety of supergravity theories may be shown to originate in the product of the contents and R-symmetries of two super Yang-Mills theories. Here we apply these ideas to twin supergravities, pairs of theories with identical bosonic sectors but di fferent supersymmetric completions, to demonstrate that they are related in a controlled fashion through the underlying Yang-Mills factors. This has the additional advantage of giving a prescription for constructing new examples of factorisable supergravities from known ones. The second part of the thesis is devoted to the study of the gauge symmetries of linearised axion-dilaton gravity by adopting a Becchi-Rouet-Stora-Tyutin (BRST) covariant formulation of Yang-Mills. The content, BRST and anti-BRST transformations as well as the equations of motion of the gravitational side are shown to be related to those of the gauge theory side by means of a dictionary building the gravity fields as sums of convolutions of Yang-Mills potentials and ghosts, thus providing a fully Lorentz-covariant version of the Yang-Mills Squared map. The anti-BRST transformations of the Kalb-Ramond 2-form sector are shown to naturally anti-commute with BRST in this formalism.
