description: As an ubiquitous method in natural language processing, word embeddings are extensively employed to map semantic properties of words into a dense vector representation. They capture semantic and syntactic relations among words but the vectors corresponding to the words are only meaningful relative to each other. Neither the vector nor its dimensions have any absolute, interpretable meaning. We introduce an additive modification to the objective function of the embedding learning algorithm that encourages the embedding vectors of words that are semantically related to a predefined concept to take larger values along a specified dimension, while leaving the original semantic learning mechanism mostly unaffected. In other words, we align words that are already determined to be related, along predefined concepts. Therefore, we impart interpretability to the word embedding by assigning meaning to its vector dimensions. The predefined concepts are derived from an external lexical resource, which in this paper is chosen as Roget's Thesaurus. We observe that alignment along the chosen concepts is not limited to words in the Thesaurus and extends to other related words as well. We quantify the extent of interpretability and assignment of meaning from our experimental results. Manual human evaluation results have also been presented to further verify that the proposed method increases interpretability. We also demonstrate the preservation of semantic coherence of the resulting vector space by using word-analogy and word-similarity tests. These tests show that the interpretability-imparted word embeddings that are obtained by the proposed framework do not sacrifice performances in common benchmark tests.

Pd based Inorganic Hollow Fibre Membranes for H2 Permeation and Methylcyclohexane Dehydrogenation
Creators: name: Mohamed Dzahir, Mohd Irfan Hatim
Publisher: name: Imperial College London
Year: 2011

description: The availability of inorganic membranes which can withstand high temperatures and harsh chemical environments has resulted in a wide range of opportunities for the application of membranes in chemical reactions and separations. In particular, the combination of membrane separation and catalytic reaction into a single operating unit is an attractive way to increase conversions, improve yields and more efficient use of natural resources in many reactions. In this study, asymmetric alumina hollow fibres with different macrostructures consisting of finger-like macrovoids and a sponge-like packed pore structure in varying ratios have been prepared by a combined phase inversion/sintering technique. The asymmetric membranes in hollow fibre geometry possess superior surface area to volume ratios with less gas permeation resistance in comparison to commercial symmetric membranes in tubular and disk configurations. Such asymmetric hollow fibres are used as substrates onto which a Pd membrane is directly deposited by an electroless plating (ELP) technique without any pre-treatment of the substrate surface. A systematic study of the electroless plating of Pd and Ag onto an asymmetric alumina hollow fibre substrate has been carried out by direct measurement of one of the gaseous products, i.e. N2, using gas chromatography (GC). In addition, the influences of the substrate macrostructure on hydrogen permeation through the Pd/Al2O3 composite membranes have been investigated both experimentally and theoretically. Furthermore, a multifunctional Pd/alumina hollow fibre membrane reactor (HFMR) has been developed and employed for the catalytic dehydrogenation of methylcyclohexane (MCH) to toluene (TOL). The developed HFMR consists of a thin and defect-free Pd membrane coated directly onto the outer surface of an asymmetric alumina hollow fibre substrate. 50 wt% Ni/Al2O3 nano-sized catalysts were directly impregnated into the substrate. The performance of HFMR has also been compared with several different reactor configurations.

description: The newspaper article draws the attention to the Butser Ancient Farm Research Project, in with that, the presentation of experimental archaeology. P.J. Reynolds explains how experimental archaeology can contribute to data sets and science, including that the project in Little Butser applies to different aspects of research, like botanical data or archaeological constructions. The method of experimental archaeology answers questions of how, why, and what. These questions were often ignored in past sciences, but can bring more answers, and more questions, to the field of archaeology.

description: A class X1.5 flare started on the solar limb at 00:43 UT on 21 April 2002, which was associated with a CME observed at 01:27 UT by LASCO C2. The coordinated analyses of this flare include TRACE 195 Å images and SUMER spectra in lines of Fe XXI, Fe XII, and C II. We find that: 1) The flare began with a jet seen by TRACE, which was detected by SUMER in the C II line as a strong brightening with blue shifts up to 170 km s$^{-1}$. At that time only weak emission was detected in Fe XII and Fe XXI. 2) Subsequently, a weak looplike brightening started south of the jet, moving outwards with an average speed of about 150 km s$^{-1}$. The SUMER spectra responded this moving loop as separatingly brightenings, visible only in the Fe XXI line. The southwards moving component contains red- and blue-shifted emission features and has an apparent speed of $\sim$120 km s$^{-1}$. The absence of signatures in Fe XII and C II lines indicates that the moving weak loop seen by TRACE corresponds to the emission from very hot plasma, in a blend line in the 195 Å bandpass due to Fe XXIV formed at T > 10 MK. 3) The trigger mechanism of the flare and associated CME can be interpreted in the same way as that proposed by Wang et al. (2002) for an event with similar initial features.

SRC willow development, biomass composition and biofuel potential
Creators: name: Brereton, Nicholas James Beresford
Publisher: name: Imperial College London
Year: 2011

description: The aims of this PhD were to examine nitrogen allocation and partitioning in Short Rotation Coppice (SRC) willow in regard to tree development and to investigate biomass composition and cell wall structure for the purpose of assessing and understanding biofuel potential. To address these topics four major experiments were performed and are presented in the thesis. An investigation of SRC willow development and nitrogen dynamics was conducted as a pot trial comprising 14 different genotypes from a willow mapping population. The genotypes were selected on the extremity and consistency of their field biomass yields. Fertiliser enriched with the stable isotope nitrogen 15 was applied as a means of nitrogen surveillance. One of the findings was that higher biomass yielding varieties of SRC willow had increased nitrogen-use-efficiency yet less (or later) nitrogen remobilisation in the autumn. The recalcitrance of the cell wall to enzymatic saccharification was assessed across 138 field-grown genotypes of the same willow mapping population. The aim was to identify any relationships between glucose yield and several biomass yield traits and to identify any quantitative trait loci (QTL) associated with enzymatic saccharification. Four QTL associated to enzymatic saccharification were identified and no relationship was found between glucose and biomass yield traits. A third experiment aimed to modify cell wall composition and structure of a single cultivar of willow grown in a pot trial. Tension wood, fibre cells containing an extra cell wall layer unique to angiosperms, and cellulose synthesis inhibited phenotypes were both induced. These modifications were accomplished through chemical and environmental treatments during development and their impact on composition and cell wall recalcitrance was assessed. Tension wood formation was found to increase glucose yields. The final main experiment used 35 of the UK’s leading biomass yielding willow varieties, grown in the field, to assess not only the variation in composition and enzymatic saccharification but also to identify any relationships between these two traits and a variety of morphological traits. The final part of the experiment investigated how variation in these traits interacted with dilute acid pretreatment. Surprisingly lignin content did not significantly correlate with cell wall recalcitrance to enzymatic saccharification. Another important finding was that enzymatic saccharification without the pretreatment correlated with enzymatic saccharification after the pretreatment. General introduction and general materials and methods chapters are included. A final summary discussion chapter is also included in order to address the overall impact of these findings on biofuel potential.

description: The received picture of springtime in the remote past is of primitive farmers struggling to plough up their tiny fields with stick ploughs which do no more than scratch the surface of the soil. Looking at modern Iandscapes with multi-hectare sized fields, huge tractors and multi-shared ploughs, perhaps this picture is a forgivable one. Maybe forgivable, but is it true? Did Iron Age farmers have to struggle with primitive equipment which if not by definition, certainly by implication, was inefficient? An examination of the available evidence reveals a rather different outline.
Time to Discontinuation of HIV Pre-Exposure Prophylaxis and Predictors among Female Sexual Workers in South West Ethiopia

description: ABSTRACT

Background: Globally, new HIV infections are rising in key and priority population groups, including female sexual workers (FSWs), with the majority of those infections occurring in Sub-Saharan Africa. Pre-exposure prophylaxis for HIV prevention (PrEP) is an efficient and user-controlled method for preventing new HIV infections. PrEP has emerged as an effective and ethical method of preventing HIV infection in FSWs. However, early and frequent discontinuation of PrEP remains an ongoing challenge. Therefore, the objective of the study was to determine time to discontinuation of PrEP and predictors among FSWs enrolled in the HIV Pre Exposure Prophylaxis Program Package in key population friendly clinics in South West Ethiopia.

Methods: A retrospective chart review study was conducted on 565 randomly selected HIV negative FSWs who were initiated on PrEP at 14 health centers in South west Ethiopia from October 2020 to September 2021. The median time to PrEP discontinuation was estimated using Kaplan-Meier (KM) time-to-event method and distribution between groups was compared using KM survival plots and Log-rank tests at P≤0.05. To identify predictors of time to PrEP discontinuation, a Cox Proportional Hazard survival model was run, where adjusted hazard ratio (AHR), 95% CI for AHR, and P-values were used for interpretation of results.

Results: Among the 565 FSWs initiated on PrEP, 428(75.8%) discontinued therapy, with a median period of 6.48 months. Significant predictors of time to PrEP discontinuation were being in the age group of 25-30 years as compared with <18 years (AHR=0.42, 95% CI=0.33-0.54, p<0.0001), having sex without condom 6 month before initiation of PrEP (AHR=2.78, 95%=1.89-4.17, p<0.0001), facing any sexual abuse 6 month prior to initiation of PrEP (AHR=3.23, 95% CI=2.17-5.01, p<0.0001), residing outside the town where PrEP was initiated (AHR=1.69, 95% CI=1.62-2.03, P<0.0001), and receiving multi-month PrEP dispensations (AHR=1.49, 95% CI=1.21-1.86).

Conclusion:  Despite its effectiveness in preventing HIV infection, FSWs in South West Ethiopia had a high discontinuation rate of PrEP after only a very short median period of use. Tailored implementation strategies are needed to enhance PrEP retention that are tailored to FSWs, with special considerations for those at high risk of discontinuation.

Influence of Connexin Expression/Co-Expression Levels on Electrical Impulse Propagation Investigated in the HL-1 Cell Model
Creators: name: Dias, Priyanthi
Publisher: name: Imperial College London
Year: 2011

description: In the myocardium action potentials are transmitted from cell-to-cell through gap junctions. These specialised junctions play a pivotal role in regulating the speed and safety of impulse propagation by controlling the amount of depolarised current that is passed from excited to non-excited regions of the heart. In mammalian hearts gap junction proteins connexin43, connexin40 and connexin45 are co-expressed in distinctive combinations and relative quantities in functionally specialised subsets of cardiac myocyte. The functional consequences of these connexin expression/co-expression patterns in modulating impulse propagation are poorly understood. To study the relative importance of membrane excitability and electrical coupling in relation to propagation velocities, clones of the HL-1 mouse atrial myocyte tumour line were used as an in vitro cell model. Five clones were characterised for expression of myocytic markers, calcium handling proteins and connexins, two of which (#2 and #6) displayed large differences in conduction velocities using microelectrode arrays. To ascertain which factor(s) were the main determinants of speed of conduction, the membrane excitability (voltage-gated channels) and electrical coupling (gap junctions) between the two clones were compared. Sodium, L- and T-type calcium channels were present in both clones but no significant differences were found in the current densities. However, large differences were seen in expression levels of connexin43, connexin40 and connexin45. RNA interference combined with microelectrode arrays was employed to establish the relative importance of each connexin in impulse propagation. The results indicate that electrical coupling by gap junctions is a major determinant of conduction velocities in HL-1 cell lines. Further experiments using RNA interference to suppress the expression of proteins thought to play a role in the action potential parameters should help in defining the part played by either the active or passive electrical properties in action potential propagation.

description: We present the first near-linear work and poly-logarithmic depth algorithm for computing a minimum cut in a graph, while previous parallel algorithms with poly-logarithmic depth required at least quadratic work in the number of vertices. In a graph with $n$ vertices and $m$ edges, our algorithm computes the correct result with high probability in $O(m {\log}^4 n)$ work and $O({\log}^3 n)$ depth. This result is obtained by parallelizing a data structure that aggregates weights along paths in a tree and by exploiting the connection between minimum cuts and approximate maximum packings of spanning trees. In addition, our algorithm improves upon bounds on the number of cache misses incurred to compute a minimum cut.

description: Beam instabilities in the strongly magnetized electron-positron plasma of pulsar magnetospheres are considered. We analyze the resonance conditions and estimate the growth rates of the Cherenkov and cyclotron instabilities of the ordinary (O), extraordinary (X) and Alfvén modes in two limiting regimes: kinetic and hydrodynamic. As a preliminary step, we reconsider wave dispersion and polarization properties in a one dimensional pair plasma taking into account relativistic thermal effects. We then find the location of the Cherenkov and cyclotron resonance of the X, O and Alfvén waves with the particles from the primary beam. The importance of the different instabilities as a source of the coherent pulsar radiation generation is then estimated taking into account the angular dependence of the growth rates and the limitations on the length of the coherent wave-particle interaction imposed by the curvature of the magnetic field lines. We conclude, that in the pulsar magnetosphere the Cherenkov-type instabilities occur in the hydrodynamic regimes, while the cyclotron-type instabilities occur in the kinetic regime. We argue, that electromagnetic cyclotron-type instabilities on the X, O and probably Alfvén waves are more likely to develop in the pulsar magnetosphere.

description: This paper considers the communication over a quantum multiple-unicast network where r sender-receiver pairs communicate independent quantum states. We concretely construct a quantum network code for the quantum multiple-unicast network as a generalization of the code [Song and Hayashi, arxiv:1801.03306, 2018] for the quantum unicast network. When the given node operations are restricted to invertible linear operations between bit basis states and the rates of transmissions and interferences are restricted, our code certainly transmits a quantum state for each sender-receiver pair by n-use of the network asymptotically, which guarantees no information leakage to the other users. Our code is implemented only by the coding operation in the senders and receivers and employs no classical communication and no manipulation of the node operations. Several networks that our code can be applied are also given.

Sparse reduced-rank regression for imaging genetics studies: models and applications
Creators: name: Vounou, Maria
Publisher: name: Imperial College London
Year: 2012

description: We present a novel statistical technique; the sparse reduced rank regression (sRRR) model which is a strategy for multivariate modelling of high-dimensional imaging responses and genetic predictors. By adopting penalisation techniques, the model is able to enforce sparsity in the regression coefficients, identifying subsets of genetic markers that best explain the variability observed in subsets of the phenotypes. To properly exploit the rich structure present in each of the imaging and genetics domains, we additionally propose the use of several structured penalties within the sRRR model. Using simulation procedures that accurately reflect realistic imaging genetics data, we present detailed evaluations of the sRRR method in comparison with the more traditional univariate linear modelling approach. In all settings considered, we show that sRRR possesses better power to detect the deleterious genetic variants. Moreover, using a simple genetic model, we demonstrate the potential benefits, in terms of statistical power, of carrying out voxel-wise searches as opposed to extracting averages over regions of interest in the brain. Since this entails the use of phenotypic vectors of enormous dimensionality, we suggest the use of a sparse classification model as a de-noising step, prior to the imaging genetics study. Finally, we present the application of a data re-sampling technique within the sRRR model for model selection. Using this approach we are able to rank the genetic markers in order of importance of association to the phenotypes, and similarly rank the phenotypes in order of importance to the genetic markers. In the very end, we illustrate the application perspective of the proposed statistical models in three real imaging genetics datasets and highlight some potential associations.

description: The analytical and numerical investigations of the energy loss rate of the test particle in a magnetized electron plasma are developed on the basis of the Vlasov-Poisson equations, and the main results are presented. The Larmor rotation of a test particle in a magnetic field is taken into account. The analysis is based on the assumption that the energy variation of the test particle is much less than its kinetic energy. The obtained general expression for stopping power is analyzed for three cases: (i) the particle moves through a collisionless plasma in a strong homogeneous magnetic field; (ii) the fast particle moves through a magnetized collisionless plasma along the magnetic field; and (iii) the particle moves through a magnetized collisional plasma across a magnetic field. Calculations are carried out for the arbitrary test particle velocities in the first case, and for fast particles in the second and third cases. It is shown that the rate at which a fast test particle loses energy while moving across a magnetic field may be much higher than the loss in the case of motion through plasma without magnetic field.

description: Small Unmanned Aerial Systems (sUAS) must meet rigorous safety standards when deployed in high-stress emergency response scenarios; however many reported accidents have involved humans in the loop. In this paper, we, therefore, present the HiFuzz testing framework, which uses fuzz testing to identify system vulnerabilities associated with human interactions. HiFuzz includes three distinct levels that progress from a low-cost, limited-fidelity, large-scale, no-hazard environment, using fully simulated Proxy Human Agents, via an intermediate level, where proxy humans are replaced with real humans, to a high-stakes, high-cost, real-world environment. Through applying HiFuzz to an autonomous multi-sUAS system-under-test, we show that each test level serves a unique purpose in revealing vulnerabilities and making the system more robust with respect to human mistakes. While HiFuzz is designed for testing sUAS systems, we further discuss its potential for use in other Cyber-Physical Systems.

description: Recently, an infinite family of one-parameter generalisations of the Veneziano amplitude were bootstrapped using as input assumptions an integer mass spectrum, crossing symmetry, high-energy boundedness, and exchange of finite spins. This new result was dubbed the hypergeometric Veneziano amplitude, with a real-valued deformation parameter r. For concreteness we work in a setup where the lowest-mass state is a tachyon of mass $m^2_0=-1$ and using the partial-wave decomposition and the positivity of said decomposition's coefficients we are able to bound the deformation parameter to $r \geq 0$ and, also, to obtain an upper bound on the number of spacetime dimensions $D \leq 26$, which is the critical dimension of bosonic string theory.

description: The rapid development of intelligent transportation systems and connected vehicles has highlighted the need for secure and efficient key management systems (KMS). In this paper, we introduce VDKMS (Vehicular Decentralized Key Management System), a novel Decentralized Key Management System designed specifically as an infrastructure for Cellular Vehicular-to-Everything (V2X) networks, utilizing a blockchain-based approach. The proposed VDKMS addresses the challenges of secure communication, privacy preservation, and efficient key management in V2X scenarios. It integrates blockchain technology, Self-Sovereign Identity (SSI) principles, and Decentralized Identifiers (DIDs) to enable secure and trustworthy V2X applications among vehicles, infrastructures, and networks. We first provide a comprehensive overview of the system architecture, components, protocols, and workflows, covering aspects such as provisioning, registration, verification, and authorization. We then present a detailed performance evaluation, discussing the security properties and compatibility of the proposed solution, as well as a security analysis. Finally, we present potential applications in the vehicular ecosystem that can leverage the advantages of our approach.

description: Supersymmetric ground state wave functions of a model of supersymmetric quantum mechanics on $S^1$ (supersymmetric simple pendulum) are studied. Supersymmetry can be broken due to the existence of an undetermined parameter, which is interpreted as a gauge field and appears as a firm consequence of quantization on a space with a nontrivial topology such as $S^1$. The breaking does not depend on the leading term of the superpotential, contrary to the usual case. The mechanism of supersymmetry breaking is similar to that through boundary conditions of fields in supersymmetric quantum field theory on compactified space. The supersymmetric harmonic oscillator is realized in the limit of the infinite radius of $S^1$ with the strength of the oscillator being constant.

Optimal Transmission Investment Strategies for Sustainable Power Systems
Creators: name: Stojkovska, Biljana
Publisher: name: Imperial College London
Year: 2011

description: Maintaining security and reliability in the electricity supply is fundamental to the functioning of a modern society and drives the need for adequate transmission capacity for both market participants and customers. Planning the investment in transmission has always been a complicated undertaking due to the high development costs and long lead times. Furthermore, to anticipate the future needs of customers is a task as difficult as that of cost-effective planning and construction of new facilities. Trying to find treatments for some of these issues represents a major motivation for this thesis. This thesis investigates the problem of how much reinforcement a transmission system requires when a significant proportion of wind generation is integrated into an existing transmission system. A multi-period transmission planning model is developed for determining optimal transmission capacity by balancing amortised transmission investment costs and annual generation costs subject to network security constraints, The model employs the security-constrained DC optimal power flow formulation and applies a solver (DashXpress) to obtain the results of the remaining linear large-scale optimisation problem. This thesis begins by exploring the impact of wind generation on the determination of appropriate levels of system capacity on the transmission network starting from the premise that it is no longer cost effective to invest in sufficient network capacity to accommodate simultaneous peaks from all generators. As such, a significant finding of this study is that conventional and wind generation should share network capacity. Given the acknowledged increase in uncertainty to security of supply due to difficulties in wind generation forecast this thesis also explores the optimal sourcing of generation reserve, and investigates investment in transmission capacity to exploit the cost benefits offered by standing reserve. Finally, the thesis presents and evaluates an alternative associated with transmission operation and investment level of risk and uncertainty by introducing more flexibility to the way the transmission system is operated. Application of Quadrature Boosters and Demand Side as model of corrective control, brings savings in operating costs without jeopardizing the level of system security, enables better utilisation of existing facilities and reduces the demand for new transmission investment.

description: Brockington and Associates, Inc., conducted a cultural resources survey of the proposed Ordnance Railroad Modifications within the Naval Weapons Station, Charleston (NWS) in Berkeley County, South Carolina 11-12 March 1998. Archaeological work entailed the pedestrian survey of approximately 4.6 km (3.0 miles) of proposed rail line and an associated 6.1 ha (15 acres) of railroad “yards." These investigations involved the excavation of shovel tests at 30 m (100 ft) intervals to provide systematic coverage of the project corridor. The survey was designed to locate and to evaluate the National Register of Historic Places (NRHP) eligibility of cultural resources that may exist in the area proposed for construction of the Ordnance Railroad Modifications. This work was conducted in compliance with Sections 106 and 110 of the National Historic Preservation Act of 1966, as amended, and US Navy’s OPNAVINST 5090.1B, Chapter 23 (23-6.7), regarding the management of cultural resources on federal property. The project will be included as part of the Historic and Archaeological Resources Protection Plan for NWS (Pan American Consultants, Inc. 1997). The survey resulted in the identification of one isolated find ( a burned historic ceramic sherd recovered from the ground surface). The isolate is recommended not eligible for the NRHP. No other cultural resources were identified. Ground disturbing activities for the proposed Ordnance Railroad Modifications will have no effect on any significant cultural resources. These activities should be allowed to proceed as planned.

description: The properties of cosmic strings have been investigated in detail for their implications in early-universe cosmology. Although many variations of the basic structure have been discovered, with implications for both the microscopic and macroscopic properties of cosmic strings, the cylindrical symmetry of the short-distance structure of the string is generally unaffected. In this paper we describe some mechanisms leading to an asymmetric structure of the string core, giving the defects a quasi-two-dimensional character. We also begin to investigate the consequences of this internal structure for the microscopic and macroscopic physics.

description: A wide array of unusual phenomena has recently been uncovered in kagome solids. The charge density wave (CDW) state in the kagome superconductor AV3Sb5 in particular intrigued the community -- the CDW phase appears to break the time-reversal symmetry despite the absence of spin magnetism, which has been tied to exotic orbital loop currents possibly intertwined with magnetic field tunable crystal distortions. To test this connection, precise determination of the lattice response to applied magnetic field is crucial, but can be challenging at the atomic-scale. We establish a new scanning tunneling microscopy based method to study the evolution of the AV3Sb5 atomic structure as a function of magnetic field. The method substantially reduces the errors of typical STM measurements, which are at the order of 1% when measuring an in-plane lattice constant change. We find that the out-of-plane lattice constant of AV3Sb5 remains unchanged (within 10^-6) by the application of both in-plane and out-of-plane magnetic fields. We also reveal that the in-plane lattice response to magnetic field is at most at the order of 0.05%. Our experiments provide further constraints on time-reversal symmetry breaking in kagome metals, and establish a new tool for higher-resolution extraction of the field-lattice coupling at the nanoscale applicable to other quantum materials.
Stabilization for the wave equation with singular Kelvin-Voigt damping

description: We consider the wave equation with Kelvin-Voigt damping in a bounded domain. The exponential stability result proposed by Liu and Rao or Tébou for that system assumes that the damping is localized in a neighborhood of the whole or a part of the boundary under some consideration. In this paper we propose to deal with this geometrical condition by considering a singular Kelvin-Voigt damping which is localized faraway from the boundary. In this particular case it was proved by Liu and Liu the lack of the uniform decay of the energy. However, we show that the energy of the wave equation decreases logarithmically to zero as time goes to infinity. Our method is based on the frequency domain method. The main feature of our contribution is to write the resolvent problem as a transmission system to which we apply a specific Carleman estimate.

description: In 2015, the Planck Collaboration released an all-sky map of the thermal Sunyaev-Zeldovich (SZ) effect, obtained by implementing the Needlet Internal Linear Combination (NILC) method on the Planck PR2 data. The quality of the Planck data has significantly improved since then. The Planck PR4 data release offers upgraded full-sky maps in the LFI and HFI frequency bands with improved systematics and sensitivity. We present a new all-sky thermal SZ Compton $y$-parameter map derived from the Planck PR4 data using NILC and highlight improvements, particularly in noise reduction and handling residual foreground contamination. The PR4 NILC Compton $y$-parameter map has been made publicly available to support further analyses.

Non-invasive imaging of estrogen receptor-coregulator interaction by luciferase fragment complementation
Creators: name: Lake, Madryn
Publisher: name: Imperial College London

description: Breast cancer is the most common cancer in the UK and approximately 1 in 8 women will be affected by the disease. Estrogen regulates breast cancer growth through the action of the estrogen receptors ERα and ERβ. Antiestrogens, in particular tamoxifen, have contributed greatly to the reduction in breast cancer mortality. Tamoxifen is a tissue selective antiestrogen; it is antiestrogenic in the breast but estrogenic in other tissues, thereby enabling it to promote the beneficial effects of estrogen, such as maintaining bone density. However, like estrogen, tamoxifen also promotes endometrial cancer, so there is an impetus for the development of novel tissue selective ERα ligands. Regulation of gene expression by the estrogen receptors requires the ligand-regulated recruitment of transcription coregulator proteins. In breast cancer ERα-coactivator interactions are associated with tumour progression while ERα-corepressor interactions are associated with receptor antagonism and a therapeutic block of ERα signalling. This thesis details the development of a luciferase fragment complementation assay to image the interaction of ERα with the coactivator AIB1 and corepressor SMRT. It is hoped that elucidation of these interactions will enable a greater appreciation of the tissue selective actions of ERα ligands and aid in the screening of novel ERα antagonists. By means of complimentary luciferase fragment fusion proteins, it is shown that ligand dependent ERα-coregulator interaction can be imaged in vitro and in vivo. ERα and AIB1 luciferase fusion proteins indicate an E2 induced increase in luciferase fragment complementation which is modulated by antiestrogens. The complementation observed correlates with ERα transcriptional activity and the specificity has been further validated by ERα fusion protein mutants. Consistent with the notion that the ERα-SMRT interaction is characteristic of ERα antagonism, ERα and SMRT fusion proteins show increased luciferase fragment complementation with antiestrogens compared with estrogen.
