Side information aware source and channel coding in wireless networks
Creators: name: Estella Aguerri, Inaki
Publisher: name: Imperial College London
Year: 2014

description: Signals in communication networks exhibit significant correlation, which can stem from the physical nature of the underlying sources, or can be created within the system. Current layered network architectures, in which, based on Shannon’s separation theorem, data is compressed and transmitted over independent bit-pipes, are in general not able to exploit such correlation efficiently. Moreover, this strictly layered architecture was developed for wired networks and ignore the broadcast and highly dynamic nature of the wireless medium, creating a bottleneck in the wireless network design. Technologies that exploit correlated information and go beyond the layered network architecture can become a key feature of future wireless networks, as information theory promises significant gains. In this thesis, we study from an information theoretic perspective, three distinct, yet fundamental, problems involving the availability of correlated information in wireless networks and develop novel communication techniques to exploit it efficiently. We first look at two joint source-channel coding problems involving the lossy transmission of Gaussian sources in a multi-terminal and a time-varying setting in which correlated side information is present in the network. In these two problems, the optimality of Shannon’s separation breaks down and separate source and channel coding is shown to perform poorly compared to the proposed joint source-channel coding designs, which are shown to achieve the optimal performance in some setups. Then, we characterize the capacity of a class of orthogonal relay channels in the presence of channel side information at the destination, and show that joint decoding and compression of the received signal at the relay is required to optimally exploit the available side information. Our results in these three different scenarios emphasize the benefits of exploiting correlated side information at the destination when designing a communication system, even though the nature of the side information and the performance measure in the three scenarios are quite different.

Coherent chaos interest rate models and the wick calculus in finance
Creators: name: Hadjipetri, Stala
Publisher: name: Imperial College London
Year: 2014

description: This thesis develops new tools in stochastic analysis with applications to finance. The first part presents novel developments in the Wiener chaos approach to the modelling, calibration, and pricing of interest rate derivatives. To price financial instruments it suffices to specify the pricing kernel, which in Brownian models can be represented as the conditional variance of a square-integrable random variable which serves as the “generator" of the pricing kernel. The coefficients of the chaos expansion of the generator act as the parameters of a generic interest-rate model. A special class of generators, arising from “coherent" chaos expansions, is considered, and the resulting interest rate models are investigated. Coherent representations are important since a kernel generator can be expressed as a linear superposition of coherent generators. This property is exploited to derive general expressions for the pricing kernel, along with the associated discount bond and short rate processes. Pricing formulae for bond options and swaptions are obtained in closed form. The pricing kernel of a generic incoherent model is then obtained by use of the underlying coherent elements. Finite-dimensional representations of coherent chaos models are investigated, and used to construct a class of tractable models having the feature that discount bond prices are piecewise-flat processes. In the second part of the thesis, a general theory of the Wick calculus is developed. Novel results concerning the Wick orders of random variables are derived. In the case where the underlying process is a Brownian motion the Wick calculus reduces to the Ito calculus, but the former is not restricted to the Gaussian class, and is applicable to other cases, such as Lévy processes. With financial applications in mind, the Wick calculus is extended to a wider class of stochastic processes. The thesis concludes with a change of measure analysis for Wick exponentials of Lévy processes, indicating that the Wick calculus can be used as a tool for modelling the dynamics of asset prices.

description: We review previous results on the clustering and environments of QSOs. We show that the correlation length for QSOs derived from existing surveys is r~5/h Mpc, similar to the observed correlation length for field galaxies at the present epoch. The galaxy environment for z<1 radio-quiet QSOs is also consistent with field galaxies. The evolution of the QSO correlation length with redshift is currently uncertain, largely due to the small numbers of QSOs (~2000) in surveys suitable for clustering analysis. We report on intial progress with the AAT 2dF QSO redshift survey, which, once completed will comprise almost 30000 QSOs. With over 1000 QSOs already observed, it is already the largest single homogeneous QSO survey. We discuss prospects for deriving limits on cosmological parameters from this survey, and on the evolution of large-scale structure in the Universe.

description: We present measurements of radio transmission in the $\sim$100 MHz range through a $\sim100$ m deep region below the surface of the ice at Summit Station, Greenland, called the firn. In the firn, the index of refraction changes due to the transition from snow at the surface to glacial ice below, affecting the propagation of radio signals in that region. We compare our observations to a finite-difference time-domain (FDTD) electromagnetic wave simulation, which supports the existence of three classes of propagation: a bulk propagation ray-bending mode that leads to so-called "shadowed" regions for certain geometries of transmission, a surface-wave mode induced by the ice/air interface, and an arbitrary-depth horizontal propagation mode that requires perturbations from a smooth density gradient. In the non-shadowed region, our measurements are consistent with the bulk propagation ray-bending mode both in timing and in amplitude. We also observe signals in the shadowed region, in conflict with a bulk-propagation-only ray-bending model, but consistent with FDTD simulations using a variety of firn models for Summit Station. The amplitude and timing of our measurements in all geometries are consistent with the predictions from FDTD simulations. In the shadowed region, the amplitude of the observed signals is consistent with a best-fit coupling fraction value of $2.4$% (0.06% in power) or less to a surface or horizontal propagation mode from the bulk propagation mode. The relative amplitude of observable signals in the two regions is important for experiments that aim to detect radio emission from astrophysical high-energy neutrinos interacting in glacial ice, which rely on a radio propagation model to inform simulations and perform event reconstruction.

description: This working paper analyses the financial cost and benefit of adopting two different bundles of climate-smart agriculture (CSA) practices, which are tailored for the diverse conditions that prevail in southern Malawi. The results show the integration of CSA practices, including soil conservation, agroforestry, and livestock diversification, into conventional maize-legume and maize monocrop systems is profitable for farmers. Moreover, the profitability of these systems increases under extreme weather conditions that occur with increasing frequency in the region. However, the upfront costs and cost variability associated with the adoption of these CSA scenarios is high relative to conventional practices. In addition, while the Net Present Value is positive for the CSA scenarios, the monetary returns are small and are spread over a long investment period. These factors act as significant barriers to adopting CSA practices. Supporting farmers through climate financing or other mechanisms to make long-term private investment in CSA, based on the public benefits these investments generate for the environment, is critical for achieving widespread adoption.

Safe and scalable parallel programming with session types
Creators: name: Ng, Chun Wang Nicholas
Publisher: name: Imperial College London
Year: 2014

description: Parallel programming is a technique that can coordinate and utilise multiple hardware resources simultaneously, to improve the overall computation performance. However, reasoning about the communication interactions between the resources is difficult. Moreover, scaling an application often leads to increased number and complexity of interactions, hence we need a systematic way to ensure the correctness of the communication aspects of parallel programs. In this thesis, we take an interaction-centric view of parallel programming, and investigate applying and adapting the theory of Session Types, a formal typing discipline for structured interaction-based communication, to guarantee the lack of communication mismatches and deadlocks in concurrent systems. We focus on scalable, distributed parallel systems that use message-passing for communication. We explore programming language primitives, tools and frameworks to simplify parallel programming. First, we present the design and implementation of Session C, a program ming toolchain for message-passing parallel programming. Session C can ensure deadlock freedom, communication safety and global progress through static type checking, and supports optimisations by refinements through session subtyping. Then we introduce Pabble, a protocol description language for designing parametric interaction protocols. The language can capture scalable interaction patterns found in parallel applications, and guarantees communication-safety and deadlock-freedom despite the undecidability of the underlying parameterised session type theory. Next, we demonstrate an application of Pabble in a workflow that combines Pabble protocols and computation kernel code describing the sequential computation behaviours, to generate a Message-Passing Interface (MPI) parallel application. The framework guarantees, by construction, that generated code are free from communication errors and deadlocks. Finally, we formalise an extension of binary session types and new language primitives for safe and efficient implementations of multiparty parallel applications in a binary server-client programming environment. Our exploration with session-based parallel programming shows that it is a feasible and practical approach to guaranteeing communication aspects of complex, interaction-based scalable parallel programming.

High performance in surgery

Publisher: name: Imperial College London
Year: 2014

description: The national identification of high performing providers in surgery is of prime importance to patients, surgeons and commissioners of healthcare. This thesis explores how high performance is identified, defined and measured nationally and attempts to identify the factors that underlie high performance in colorectal cancer surgery during the peri-operative period. An introduction into the determinants of high performance in surgery as well as defining quality as it pertains to surgery is then undertaken. Identification of available national data sources and metrics for national performance are then identified. Comparison is made between voluntary and compulsory reporting systems highlighting greater capture of peri-operative mortality in compulsory reporting datasets. A novel marker that reflects outcome following complication management is developed. This marker is based on re-operations and is derived from compulsory reporting datasets. The use of non-operative re-interventions is then assessed in oesophago-gastric cancer resections as proof of concept. An appraisal of all colorectal cancer units in England is then undertaken using a panel of metrics demonstrating that analysis on a single marker alone may be too simplistic. Identifying factors that pertain to high performance beyond those available from routinely available datasets using a novel methodological approach called HiPer (High Performance) is performed. The interview based methodology identified rich qualitative factors in a group of colorectal cancer units worldwide that may be causal in their performance status. Finally, results from the interview study were related to hard outcome data from each unit which demonstrated some correlation between the HiPer methodology and the outcome data in the final section of the feasibility study. The implications of this may be that a dual approach of analysing routinely collected data with a more qualitative HiPer style methodology may help us better understand how high performing units achieve their results.

INTERNATIONAL BOTTOM TRAWL SURVEY (IBTS)

description: L'objectif principal des campagnes IBTS est de produire des indices biologiques pour caractériser l'état et l'évolution à moyen terme des espèces exploitées et des peuplements d'intérêt halieutique. Ces campagnes sont nécessaires pour l'évaluation des stocks de poissons commerciaux au travers d'indices d'abondance par âge pour ces espèces. Mises en place dans les années 70, les campagnes se sont progressivement standardisées et depuis les années 80, un protocole commun a été a été défini au niveau international. Tous les pays riverains de la mer du Nord qui participent à cette campagne utilisent un engin et des méthodes de travail identiques. De plus, pour évaluer les indices d'abondance larvaire (groupe 0 pour le hareng), un échantillonnage de nuit au filet MIK (Methot Isaac Kidd) couvrant la même zone que les chalutages, est également réalisé selon un même protocole standard (Fig.1) Depuis plus de 20 ans, la France échantillonne la moitié sud de la mer du Nord. Et depuis 2007, la Manche orientale a été intégrée à la zone d'échantillonnage IBTS suite à une demande Française. En effet, les interactions et les échanges entre ces deux bassins étant importants, la Manche orientale est souvent associée à la mer du Nord dans les évaluations de la plupart des stocks de poissons. Le hareng par exemple est exploité en mer du Nord tout au long de l'année, mais vient se reproduire au large des côtes françaises vers les mois de novembre et décembre. Un échantillonnage de cette zone durant la campagne IBTS permet d'obtenir un indice larvaire plus précis pour cette espèce.Figure 1: Distribution of traits among countries participating in the IBTS campaign.La gestion des pêches s'intègre maintenant dans une approche écosystémique. Progressivement, la campagne IBTS est donc devenue une campagne pluridisciplinaire où l'ensemble de l'écosystème est étudié grâce aux différents travaux menés en parallèle : Oeufs et larves de poissons, macroinvertébrés benthiques, phyto et zooplancton.

An investigation into the efficacy of single low dose of insulin in the prevention of excessive cutaneous scarring in breast surgery
Creators: name: Hallam, Marc-James
Publisher: name: Imperial College London
Year: 2015

description: Early human fetuses have the ability to heal wounds by completely regenerating tissues, leaving no evidence of scarring. However in the adult scarring is the inevitable endpoint of the wound healing process. Sometimes these scars can be pathological in nature causing both functional and aesthetic problems to those affected. Every year millions of people around the globe acquire problematic or pathological scars either whilst undergoing surgery or from traumatic injuries and at present there remain a severely limited number of pharmacological treatment options to offer these patients. Importantly currently there exists no treatment that can either eliminate or reliably reduce acquired scars. Not only is the treatment of acquired scars problematic but also the clinical assessment of scars is largely subjective in nature and frequently relies on assessment scales that show large amounts of inter-rater variation and lack quantification. Especially subjective is the measurement of scar colour, which can be markedly different from the surrounding skin and cause significant distress to the patient. Without an objective assessment framework clinicians cannot reliably examine scars nor gauge responses to any treatment. The aim of this thesis is thus two-fold. Firstly a new anti-scarring treatment in the form of insulin will be tested in a randomised, double blind, intra-patient, placebo controlled trial where patients undergoing elective bilateral breast surgery will have low-dose insulin injected subcutaneously to one breast and placebo to the other at the time of surgery. Patients will be followed up for 12 months and their scars compared to examine the therapeutic effect of insulin upon scars. Secondly the thesis aims to test the validity of new methods of assessing the scar colour of a subset of patients within the insulin trial using previously untested photographic devices and software. These devices are hoped to add much needed quantification to scar assessment.

Potentials are derived from this Lagrangian and used in a coupled-channel calculation of the low energy observables. The potentials are constructed such that in the Born approximation the s-wave scattering amplitude is the same as that given by the effective chiral Lagrangian, up to order $q^2$. Comparison is made with the available low energy hadronic data of the coupled $K^-p, Σπ, Λπ$ system, which includes the $Λ(1405)$ resonance, $K^-p$ elastic and inelastic scattering, and the threshold branching ratios of the $K^-p$ decay. Good fits to the experimental data and estimates of previously unknown Lagrangian parameters are obtained.

description: We have discovered unusual behavior of polymer coils in a binary solvent (nitroethane+isooctane) near the critical temperature of demixing. The exceptionally close refractive indices of the solvent components make the critical opalescence relatively weak, thus enabling us to simultaneously observe the Brownian motion of the polymer coils and the diverging correlation length of the critical fluctuations. The polymer coils exhibit a collapse-reswelling-expansion-collapse transition upon approaching the critical temperature. While the first stage (collapse-reswelling) can be explained by the theory of Brochard and de Gennes, the subsequent expansion-collapse transition is a new unexpected phenomenon that has not been observed so far. We believe that this effect is generic and attribute it to micro-phase separation of the solvent inside the polymer coil.

description: The exact mechanism of miR-15a-5p shuttled by human umbilical cord-mesenchymal stem cell-derived exosomes (hUC-MSCs-Exo) in Wilms tumor (WT) was estimated. WT tissues were collected clinically. miR-15a-5p and septin 2 (SEPT2) expression levels were examined in tissues . hUC-MSCs-Exo were transfected with miR-15a-5p-related oligonucleotides and co-cultured with WT cells (G-401). In addition, SEPT2 loss-of-function was performed in G-401 cells. The biological functions of G-401 cells after treatments were evaluated. Moreover, tumor formation tests further assessed the role of exosomal miR-15a-5p in WT. The miR-15a-5p level was lower and the SEPT2 level was higher in WT. hUC-MSCs-Exo impaired the biological functions of G-401 cells. hUC-MSCs-Exo carried upregulated miR-15a-5p into G-401 cells, thereby lessening the tumorigenic properties of G-401 cells. Inhibition of SEPT2 suppressed the biological function of WT cells and upregulated SEPT2 reversed hUC-MSCs-Exo-mediated inhibition of G-401 cell growth. The tumorigenicity of G-401 cells in mice was impaired by hUC-MSCs-Exo overexpressing miR-15a-5p. The data prove that miR-15a-5p shuttled by hUC-MSCs-Exo negatively regulates SEPT2 expression, and disrupts WT cell growth in vivo and in vitro.

We calculate the equilibrium structure in the general relativistic two-fluid formalism with entrainment effect where we take neutron superfluid as one fluid and the other fluid is comprised of protons and electrons, making it a charge neutral fluid. We use a relativistic mean field model for the equation of state of matter where the interaction between baryons is mediated by the exchange $σ$, $ω$ and $ρ$ mesons. Then, we study the linear, static $l=2$ perturbation on the star to compute the electric-type Love number following Hinderer's prescription.

description: We report results of a near--infrared imaging survey of L977, a dark cloud in Cygnus seen in projection against the plane of the Milky Way. We use measurements of the near--infrared color excess and positions of the 1628 brightest stars in our survey to measure directly dust extinction through the cloud following the method described by Lada et al. (1994). We spatially convolve the individual extinction measurements with a square filter 90" in size to construct a large-scale map of extinction in the cloud. We derive a total mass of M(L977)= (660 +/- 30)(D/500 pc)^2 Msun and, via a comparison of source counts with predictions of a galactic model, estimate a distance to L977 of 500 +/- 100 pc. We find a correlation between the measured dispersion in our extinction determinations and the extinction. We interpret this as evidence for the presence of structure on scales smaller than the 90" resolution of our extinction map. To further investigate the structure of the cloud we construct the frequency distribution of the 1628 individual extinction measurements in the L977 cloud. The shape of the distribution is similar to that of the IC 5146 cloud. Monte Carlo modeling of this distribution suggests that between 2 < Av < 40 mag (or roughly 1 < r < 0.1 pc) the material inside L977 is characterized by a density profile n(r) \propto r^(-2). Direct measurement of the radial profile of a portion of the cloud confirms this result. (more...)

description: We present powerful new analysis techniques to constrain effective field theories at the LHC. By leveraging the structure of particle physics processes, we extract extra information from Monte-Carlo simulations, which can be used to train neural network models that estimate the likelihood ratio. These methods scale well to processes with many observables and theory parameters, do not require any approximations of the parton shower or detector response, and can be evaluated in microseconds. We show that they allow us to put significantly stronger bounds on dimension-six operators than existing methods, demonstrating their potential to improve the precision of the LHC legacy constraints.

description: We develop, discuss, and compare several inference techniques to constrain theory parameters in collider experiments. By harnessing the latent-space structure of particle physics processes, we extract extra information from the simulator. This augmented data can be used to train neural networks that precisely estimate the likelihood ratio. The new methods scale well to many observables and high-dimensional parameter spaces, do not require any approximations of the parton shower and detector response, and can be evaluated in microseconds. Using weak-boson-fusion Higgs production as an example process, we compare the performance of several techniques. The best results are found for likelihood ratio estimators trained with extra information about the score, the gradient of the log likelihood function with respect to the theory parameters. The score also provides sufficient statistics that contain all the information needed for inference in the neighborhood of the Standard Model. These methods enable us to put significantly stronger bounds on effective dimension-six operators than the traditional approach based on histograms. They also outperform generic machine learning methods that do not make use of the particle physics structure, demonstrating their potential to substantially improve the new physics reach of the LHC legacy results.

description: Significant Properties (SPs) have been in the digital preservation literature for a decade or more. There has been widespread agreement on the important role they play, but no consensus on exactly *what* is significant.
Investigating the Significant Properties of Electronic Content over Time (InSPECT) aimed to expand and articulate the concept of ‘significant properties’, determine sets of significant properties for a specified group of digital object types, evaluate methods for measuring these properties for a sample of relevant representation formats, investigate and test the mapping and comparison of these properties between different representation formats, and identify any issues requiring further research.
This report outlines the methodology adopted by the InSPECT project to identify, analyse and evaluate information properties considered significant

Multiscale modelling of structural and electronic properties of organic thin films

Publisher: name: Imperial College London

description: In this thesis, we develop aspects of a framework for the multi-scale modelling of charge transport in several organic semiconductors relevant for technological application. In the first chapter, we build a coarse-grained model for fullerene multi-adducts which clearly distinguishes between the influence of energetic and structural disorder. The model reveals that charge transport in fullerene multi-adducts is limited by energetic disorder due to different isomers. Solar cells containing single isomers of higher fullerene adducts are expected to achieve higher power conversion efficiencies. Secondly, we create a multi-scale model to investigate the effect of beta-phase conformers on hole transport in poly(9,9)dicotylfluorene. A combination of quantum-chemical calculations and charge transport simulation confirms that beta-phase conformers act as traps and, when torsional disorder of the polymer backbone is included, can explain the experimentally observed mobility reduction due to beta-phase. In the third project, grain boundaries in tri-isopropylsilylethynyl (TIPS) pentacene are characterised. On the basis of two-grain structures with varied mutual orientation generated with atomistic molecular dynamics, we compute energy landscapes and electronic coupling elements. We find that the effect of the grain boundary is relatively weak for long interfaces, but that small contact areas between grains may impede charge transport more strongly due to highly non-uniform energy barrier heights. The final chapter focuses on one-dimensional organic magnetoresistors with alternating acceptor, spacer and donor units. Combining quantum-chemical calculations and kinetic Monte-Carlo simulations allow us to define design rules for high magnetoresistance, among which minimising the offset between HOMO and LUMO energy levels is the most challenging one. Within the range of researched materials, polymers built from dicyanoqyinonediimine (DCNQI) acceptors, fluorene spacers and 3-ethylendioxythiophene (3-EDOT) donors are most promising for magentoresistance application.

description: In dieser Thesis wird ein Time-to-Digital Converter mit einer Sub-Gate-Delay Auflösung, also einer höheren Auflösung als die Durchlaufzeit eines in dieser Prozesstechnik realisierten Inverters, mithilfe verschiedener Ansätze, wie dem Vernier TDC oder dem Local Passive Interpolation TDC, untersucht. Hierbei wird eine Delay-Locked Loop genutzt, um die Durchlaufzeit der jeweiligen Inverterkette zu regeln. Der Vorteil dieses Ansatzes ist, dass die Durchlaufzeit auch bei PVT-Variationen, also Variation der Prozesscorner, Versorgungsspannung und Temperatur, auf die Referenzperiodendauer eingestellt wird. Somit sind lokale Prozessabweichungen die vorherrschende Quelle für Ungenauigkeiten in der Auflösung des TDC. Die Auflösung kann mithilfe der differentialen und integralen Nichtlinearität beschrieben und ausgewertet werden.
