Mathematical Modelling of Spatially Coherent Transcription
Creators: name: Swingland, James Thomas
Publisher: name: Imperial College London
Year: 2012

description: Genetics and epigenetics are widely expected to revolutionise our understanding of health and disease. However any attempt to extract relevant information from noisy data requires a combination of modelling and statistical techniques. Given the number of genes and the complexity involved in the genome, sophisticated methods will be needed to properly capture the information that is contained. Many mechanisms and variables can affect and control the expression of a gene. In this thesis, it is specifically spatially coherent variations in transcription which are investigated. Several different areas were examined, producing a broad set of results. Important findings include the demonstration of spatial coherence as the result of epigenetic effects, the creation and validation of a technique to detect spatial coherence, and the extension of spatial modelling to epigenetic data. Other important results include the detection of spatial coherence variation due to confounding variables (PMI and neuronal concentration) and the development of new spatial modelling techniques. The results indicate that spatial modelling provides a useful approach to investigating unusual and unknown aspects of epigenetic and transcriptional regulation.

description: A third possible explanation for the X-ray emission from the z=2.156 radio galaxy 1138-262 is thermal emission from a very dense, sub-cluster `halo', perhaps associated with the (forming) cD galaxy on a scale < 100 kpc. For instance, increasing the gas density from 0.01 cm^{-3} to 0.1 cm^{-3} would decrease the required hot gas mass by the same factor, and could possibly alleviate constraints on cosmological structure formation models. The pressure in this gas would be very high (10^{-9} dynes cm^{-2}), comparable to the pressure in the optical line emitting nebulosity and to the minimum pressure in the radio source, and the cooling time would be short (< fewx10^{8} years). Circumstantial evidence for such very dense, hot gas enveloping some high z radio sources has been reviewed by Fabian et al. (1986). Fabian (1991) suggests that in some cases the `inferred pressures are close to the maximum that can be obtained by gas cooling in a potential well of a galaxy' (ie. the cooling time = gravitational free-fall time), and he designates such systems as `maximal cooling flows', with implied cooling flow rates up to 2000 M_solar year^{-1}. High resolution X-ray imaging with AXAF should be able to test whether 1138-262 has a normal cluster atmosphere, a `maximal cooling flow', or an unusually X-ray loud AGN.

Sigma-model symmetry in orientifold models
Creators: name: Scrucca, Claudio A.

Publisher: name: arXiv
Year: 2000
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We investigate in the simplest compact D=4 N=1 Type IIB orientifold models the sigma-model symmetry suggested by the proposed duality of these models to heterotic orbifold vacua. This symmetry is known to be present at the classical level, and is associated to a composite connection involving untwisted moduli in the low-energy supergravity theory. In order to study possible anomalies arising at the quantum level, we compute potentially anomalous one-loop amplitudes involving gluons, gravitons and composite connections. We argue that the effective vertex operator associated to the composite connection has the same form as that for a geometric deformation of the orbifold. Assuming this, we are able to compute the complete anomaly polynomial, and find that all the anomalies are canceled through a Green-Schwarz mechanism mediated by twisted RR axions, as previously conjectured. Some questions about the field theory interpretation of our results remain open.

Complex-angle analysis of electromagnetic waves on interfaces

Publisher: name: arXiv
Year: 2018
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: Electromagnetic wave is reflected and refracted at interfaces, satisfying Fresnel-Snell law which is required by conservations of energy and momentum. If the incident angle is lower than the critical angle, we can use this Fresnel-Snell law, but the Fresnel-Snell law is modified in the case of existence of dissipation ($\tilde{n} = n + iκ, κ> 0$) or in the condition of total internal reflection. In the cases, we have to extend the angle of refraction from real number to complex number ($θ\rightarrow \tildeθ = θ+ iψ, ψ\neq 0$). In this paper, by using complex-angle approach, we analyse the behaviour of electromagnetic waves in various kind of interfaces: dielectric - dielectric system, dissipative dielectric - dielectric system, and metal - dielectric system. We show that iso-frequency curves in wavenumber space is opened in the case where $n, κ> 0$, and closed either when $n \rightarrow 0$ or when $κ\rightarrow 0$ ("Lifshitz transition" of electromagnetic waves). Excess momentum (wavenumber) and anomalous spin (circular polarization) emerging with the transition are also discussed.
Quantum correlations and entanglement in a Kitaev-type spin chain

description: The entanglement and quantum correlation measures have been investigated for the ground state of a spin chain with a Kitaev-type exchange interactions on alternating bonds, along with a transverse magnetic field. There is a macroscopic degeneracy in the ground state for zero magnetic field, implying a quantum critical point. But peculiarly in this model, the entanglement measures do not show any singular behavior in the vicinity of the critical point, as seen in the transverse Ising model ground state and related models. We have investigated different correlation measures analytically, that have been used for many solvable spin systems to track a quantum critical point. We compute the pair concurrence measure of entanglement, the pair quantum discord to track the quantum correlations, and a global entanglement measure and a multi-species entanglement measure to investigate multi-party entanglement, both analytically and numerically. The nearest-neighbor concurrence shows a peak structure as a function of magnetic field, near the critical point, for various values of the ratio of interaction strengths, but its derivative does not show a singular behavior close to the critical point. A similar behavior is shown by the quantum discord and the global entanglement. The multi-species entanglement shows the most-pronounced signature of the critical point, in its first-order derivative, though the entanglement and its derivatives have a smooth behavior in the critical region.

description: Recently, water scarcity has been a substantial problem facing agriculture in Egypt, with a great impact on food security and hence makes it a challenge to satisfy food demand. An aquaponic system with minimum water needs is considered a substitute technique to meet the demand of food shortages. Celery (Apium graveolens) is a widely cultivated herb belonging to the family Apiaceae and widely consumed as a popular ingredient in a wide range of dishes and food recipes. A total of 13 phenolic metabolites were detected and quantified using HPLC-ESI-MS/MS. Chlorogenic acid was detected as the most abundant phenolic compound accounting for 3471.58 mg kg−1. Moreover, 65 volatile compounds belonging to 12 different classes were detected using GS-MS with an abundance of aromatic hydrocarbons at ca.68.15%. and the main constituents were 6-phenyltridecane, 6-phenyldodecane, and 5-phenylundecane at ca.6.78%, 6.62%, and 6.13% respectively. It is the first time to report metabolic profile in celery grown in an aquaponic system.
Characterization of the role of the Aurora B kinase in quiescent lymphocytes
Creators: name: Frangini, Alberto
Publisher: name: Imperial College London
Year: 2012

description: The role of the Aurora B kinase in mediating cellular functions outside mitosis was investigated. A SILAC-based approach was used to show that Aurora B interacts with proteins implicated in gene regulation and chromatin organization in G1 activated B cells. Among these interactors, I identified the PRC1 component Ring1B as a new partner of Aurora B. Both proteins are bound to the promoters of highly expressed genes in resting B and T lymphocytes. Quiescent resting B cells require the maintenance of a transcriptional programme that keeps the cells viable and ready to proliferate upon encounter with a specific antigen. Aurora B and Ring1B physically co-occupy the same promoters in resting B cells but, upon activation, Aurora B is replaced by MSK1 on its target genes, whereas Ring1B binding is preserved. Analysis of the active promoters in resting B cells shows that other PRC1 components, such as Cbx7 and Bmi1, and the histone deubiquitinase USP16, together with Aurora B and Ring1B, bind almost exclusively to the regulatory elements of active promoters and are not found at repressed genes. Binding of PRC2 components and deposition of the H3K27me3 and H2Aubq marks are largely confined to silent genes. By employing conditional knockout mouse models, I showed that removal of either Aurora B or Ring1B results in a global reduction in the binding of unphosphorylated and serine 5-phosphorylated RNA Polymerase II to active promoters. This phenomenon is also accompanied by a reduction in the production of transcripts from Aurora B and Ring1B target genes and reduced cell viability. Aurora B is also required to maintain high levels of phosphorylated H3S28 and low levels of the repressive H2Aubq mark at active promoters. These results identify a new role for both Aurora B and Ring1B in the regulation of active transcription in quiescent lymphocytes.

description: Machine learning has played an important role in the analysis of high-energy physics data for decades. The emergence of deep learning in 2012 allowed for machine learning tools which could adeptly handle higher-dimensional and more complex problems than previously feasible. This review is aimed at the reader who is familiar with high energy physics but not machine learning. The connections between machine learning and high energy physics data analysis are explored, followed by an introduction to the core concepts of neural networks, examples of the key results demonstrating the power of deep learning for analysis of LHC data, and discussion of future prospects and concerns.

description: The analysis of Perseus data collected with the Medium Energy Concentrator Spectrometer (MECS) on board Beppo-SAX shows that the ratio of the flux of the 8 keV line complex (dominated by Fe K$_β$ emission) over the 6.8 keV line complex (dominated by Fe K$_α$ emission) is significantly larger than predicted by standard thermal emission codes. Moreover the analysis of spatially resolved spectra shows that the above ratio decreases with increasing cluster radius. We find that, amongst the various explanations we consider, the most likely requires the plasma to be optically thick for resonant scattering at the energy of the Fe K$_α$ line. We argue that if this is the case, then measures of the iron abundance made using standard thermal emission codes, that assume optically thin emission, can significantly underestimate the true iron abundance. In the case of the core of Perseus we estimate the true abundance to be $\sim$ 0.9 solar in a circular region with radius of $\sim 60$ kpc and centered on NGC 1275. Finally we speculate that similar results may hold for the core of other rich clusters.

description: Apache Spark is a popular system aimed at the analysis of large data sets, but recent studies have shown that certain computations---in particular, many linear algebra computations that are the basis for solving common machine learning problems---are significantly slower in Spark than when done using libraries written in a high-performance computing framework such as the Message-Passing Interface (MPI). To remedy this, we introduce Alchemist, a system designed to call MPI-based libraries from Apache Spark. Using Alchemist with Spark helps accelerate linear algebra, machine learning, and related computations, while still retaining the benefits of working within the Spark environment. We discuss the motivation behind the development of Alchemist, and we provide a brief overview of its design and implementation. We also compare the performances of pure Spark implementations with those of Spark implementations that leverage MPI-based codes via Alchemist. To do so, we use data science case studies: a large-scale application of the conjugate gradient method to solve very large linear systems arising in a speech classification problem, where we see an improvement of an order of magnitude; and the truncated singular value decomposition (SVD) of a 400GB three-dimensional ocean temperature data set, where we see a speedup of up to 7.9x. We also illustrate that the truncated SVD computation is easily scalable to terabyte-sized data by applying it to data sets of sizes up to 17.6TB.

description: We investigate new compactifications of OM theory giving rise to a 3+1 dimensional open string theory with noncommutative $x^0$-$x^1$ and $x^2$-$x^3$ coordinates. The theory can be directly obtained by starting with a D3 brane with parallel (near critical) electric and magnetic field components, in the presence of a RR scalar field. The magnetic parameter permits to interpolate continuously between the $x^0$-$x^1$ noncommutative open string theory and the $x^2$-$x^3$ spatial noncommutative U(N) super Yang-Mills theory. We discuss $SL(2,Z)$ transformations of this theory. Using the supergravity description of the large $N$ limit, we also compute corrections to the quark-antiquark Coulomb potential arising in the NCOS theory.

Localization of Matters on a String-like Defect

description: After presenting string-like solutions with a warp factor to Einstein's equations, we study localization of various spin fields on a string-like defect in a general space-time dimension from the viewpoint of field theory. It is shown that spin 0 and 2 fields are localized on a defect with the exponentially decreasing warp factor. Spin 1 field can be also localized on a defect with the exponentially decreasing warp factor. On the other hand, spin one-half and three-half fields can be localized on a defect with the exponentially increasing warp factor, provided that additional interactions are not introduced. Thus, some mechanism of localization must be invoked for these fermionic fields. These results are very similar to those of a domain wall in five space-time dimensions except the case of spin 1 field.

description: Recent breakthroughs in recurrent deep neural networks with long short-term memory (LSTM) units has led to major advances in artificial intelligence. State-of-the-art LSTM models with significantly increased complexity and a large number of parameters, however, have a bottleneck in computing power resulting from limited memory capacity and data communication bandwidth. Here we demonstrate experimentally that LSTM can be implemented with a memristor crossbar, which has a small circuit footprint to store a large number of parameters and in-memory computing capability that circumvents the 'von Neumann bottleneck'. We illustrate the capability of our system by solving real-world problems in regression and classification, which shows that memristor LSTM is a promising low-power and low-latency hardware platform for edge inference.

Mathematical techniques for free boundary problems with multiple boundaries
Creators: name: Green, Christopher
Publisher: name: Imperial College London
Year: 2013

description: In this thesis, we study six different free boundary problems arising in the field of fluid mechanics, and the mathematical methods used to solve them. The free boundary problems are all characterised by having more than one boundary and the solution of these problems requires special mathematical treatment. The challenge in each of these problems is to determine the shape of the multiple fluid interfaces making up the particular system under consideration. In each of the free boundary problems we employ aspects of complex function theory, conformal mapping between multiply connected domains, and specialist techniques devised in recent years by Crowdy and collaborators. At the heart of these techniques lies a special transcendental function known as the Schottky-Klein prime function. This thesis makes use of this function in a variety of novel contexts. We first examine a single row of so-called hollow vortices in free space. This problem has been solved before but we present a new methodology which is convenient in being extendible to the case of a double row, or von Karman vortex street, of hollow vortices. We find a concise formula for the conformal mapping describing the shapes of the free boundaries of two hollow vortices in a typical period window in the vortex street and thereby solve the free boundary problem. We next focus on the problem of a pair of hollow vortices in an infinite channel. This free boundary problem exhibits similar mathematical features to the vortex street problem but now involves the new ingredient of solid impenetrable walls. Again we solve the free boundary problem by finding a concise formula for the conformal mapping governing the hollow vortex shapes. We then extend this analysis to a single row of hollow vortices occupying the channel. The problem of a pair of hollow vortices of equal and opposite circulation positioned behind a circular cylinder, superposed with a uniform flow, is then considered. This system is a desingularisation of the so-called Foppl point vortex equilibrium. For this free boundary problem, we employ a hybrid analytical-numerical scheme and we are able to offer a Fourier-Laurent series expansion for the conformal mapping determining the shape of the hollow vortex boundaries. Finally, we investigate an asymmetric assembly of steadily translating bubbles in a Hele- Shaw channel. This free boundary problem can be formulated as a special Riemann-Hilbert problem solvable in terms of the Schottky-Klein prime function. Our method of solution can be used to determine the shapes of any finite number of bubbles in a given assembly.

The role of electricity storage in low carbon energy systems : techno-economic drivers and transistional barriers
Creators: name: Gruenewald, Philipp
Publisher: name: Imperial College London
Year: 2012

description: UK Government policy sets out ambitious aims to decarbonise the energy system. This requires fundamental changes to the existing energy infrastructure and electricity from low carbon sources is expected to play a major role in this transition. Electricity storage is widely believed to be able to support the integration of low carbon technologies. So far, the installation of wind power in the UK has not led to any significant deployment of additional storage capacity. Investors still regard electricity storage as too expensive. As more low carbon technologies are deployed, the need for storage may increase. How do these developments affect the role for electricity storage in future UK energy systems? This thesis addresses this question by combining technical, economic and social approaches. A techno-economic model has been developed to examine the commercial opportunities for electricity storage in future scenarios. A socio-technical perspective of technological transition complements this approach. Stakeholders have informed the analysis on the uptake of storage through a workshop and interviews. The results point towards a significant increase in the gross value of electricity storage, even at modest efficiencies, especially within highly renewables based scenarios. However, the concept of storing electricity is poorly aligned with existing institutions and regulatory structures. Despite the potential increase in value, electricity storage may fail to be adopted in the best societal interest. Path dependency may lead to the deployment of established alternative solutions, or favour storage technologies with unnecessarily high performance. This thesis concludes that if electricity storage is to play an effective role as part of a low carbon transition, long term developments would need to be considered as part of a strategic policy framework. These may need to address commercial as well as institutional barriers to deployment.

Morphological characterisation of porous materials for fuel cell technology
Creators: name: Hihinashvili, Rebecca
Publisher: name: Imperial College London

description: Porous materials play an important role in many applications, e.g. fuel cells, bone transplants and CO2 storage. The current thesis is motivated by the challenges faced in fuel cell technology with regard to the design and manufacture of porous electrodes. The macroscopic, observable properties of porous materials are determined by their microstructure. However, the challenge still remains in finding and formulating relations between the microstructure and the macroscopic properties. This work tests and develops further a recent method that aims at deriving such relations. The method consists of first quantifying the microstructure in terms of volume elements called quadrons. This description is then used in an entropy-based statistical mechanical formalism that makes it possible to derive macroscopic properties. We apply the quadron description to numerically generated structures: planar granular packs and 3D tetrahedral cellular structures. We find that the quadron statistics are sensitive to the microstructure. Especially, they capture information about the pores, a microstructural feature that grain-based volumes such as Voronoi cells do not capture. We evaluate the compactivity – an analog to temperature – of the planar packs using different methods. All the methods give the right relation between the compactivities of the packs. In addition, the volume distributions of the quadrons decay exponentially. These results lend support to the statistical mechanical formalism. We compare the quadron statistics of different 3D cellular structures including examples of relevant microstructural features such as the throats – the openings between two pores. Applying the reciprocity defined within the quadron description, we link between grain shapes, the number of grain contacts and the length of the TPB, which is a key property of fuel cells electrodes. This reproduces an established phenomenon in granular materials, however, this result is obtained here using cellular structures and the quadron description only.

description: This study used computational fluid dynamics (CFD) study to investigate the impact of helicopter downwash on pedestrian comfort. The initial stage of the study involves the development of a helicopter downwash model that was compared to experimental values which showed some degree of coherence with areas situated downstream of the helicopter rotor. The initial stage was used to find suitable modelling parameters and an adequate resolution of computational mesh to produce a reliable helicopter downwash model. The final stage of the study is to integrate a helicopter in a built environment and assess the impact of downwash on pedestrian comfort. The concluding stage of the study showed that helicopter downwash effects can impose discomforting conditions in the immediate vicinity of the helicopter along with some minute propagating effects further downstream. Although its magnitude is smaller compared to effects of prevailing wind a local mitigation must be separately planned to deal with the effects of helicopter downwash.

description: Lasia spinosa (L.) Thwaites rhizomes (LSR), historically utilised in traditional medicine for various health sufferings, including cancer, represent an intriguing yet underexplored reservoir of bioactive constituents. Our study focused on exploring the anticancer potential of LSR and its phytoconstituents. The methanol extract of LSR exhibited significant cytotoxicity against various cancer cell lines compared to other extracts. The fractionation of methanol extract resulted in the isolation of chlorogenic acid (CA), oleanolic acid, β-amyrin, and lyonoresinol. Molecular docking analysis of these isolated compounds targeted at the active sites of CDK-2, VEGFR-2, and ToP-2A enzymes revealed the superior docking score of CA compared to the other constituents. Additionally, density functional theory studies indicated the strong electrophilic nature of CA and its potential for robust enzyme binding interactions. Subsequent MTT assays focusing on CA exhibited significant activity against all tested cell lines, with IC50 values ranging from 21.56 to 72.60 μg/ml, comparable to quercetin.
The Genetic Mechanisms Underlying Human Obesity
Creators: name: Clark, Stephen James
Publisher: name: Imperial College London
Year: 2012

description: Obesity is becoming one the leading causes of mortality in the western world. Although environment is a factor in its development, it is highly heritable and despite a number of genes that have been found to be associated to the disease its genetics are still poorly understood. Discovery of genetic pathways that influence obesity risk can provide a better understanding of the pathophysiology of the disease and identify possible pharmacological targets for its treatment. This project was designed to investigate possible genetic associations between five candidate genes and severe obesity in both adult and child French Caucasians (n=2,822). Tag SNPs were chosen along with a selection of common SNPs not in the HapMap database and genotyped using Sequenom iPLEX assays. Putative associations were discovered to obesity in three genes, SIRT1 (corrected p-values: 0.034, 0.019), APLN (corrected p-value: 0.017) and IL11 (corrected p-value: 0.016), although associations do not withstand genome-wide correction. SIRT1 and IL11 SNPs were subsequently genotyped within a family cohort for which transcription data in adipose tissue was available. In this cohort, SIRT1 genotypes were nominally associated with BMI (corrected p-values: 0.014, 0.019, 0.014) and a significant difference in expression levels of the gene was observed between lean and obese individuals (p=1.6x10-35) providing suggestive evidence of a role of this gene in the development of obesity. Expression and genotypes of another gene, IRS1 were also analysed and although no significant associations to obesity were found, an association between SNP variation and gene expression was discovered (corrected p-value: 1.0x10-5). Another aim of this project was to investigate the possibility that DNA methylation influences obesity risk. Firstly, a method for the measurement of the quantitative trait of DNA methylation status at individual CpG sites was developed using direct sequencing. Next, methylation in the leptin gene CpG island was measured in a subset of 184 case-control samples and a nominal association was discovered between the quantitative measurement of methylation at a single CpG site and obesity (p=0.013). In summary, putative associations to obesity have been discovered with genetic variants as well as transcription levels and CpG methylation. Replication in other populations is required in order to confirm these associations.

description: We consider a multi component mixture of inert gas in the kinetic regime by assuming that the total number of particles of each species remains constant. In this article we shall illustrate our model for the case of two species. To account for thermal effects, we extend a BGK model based on the presence of a collision term for each possible interaction \cite{Pirner} by including ES-BGK effects. We prove consistency of the extended model like conservation properties, positivity of all temperatures, H-theorem and convergence to a global equilibrium in the shape of a global Maxwell distribution.

description: We describe heterotic string and M-theory realizations of the Randall-Sundrum (RS) scenario with $\cx N=2$ and $\cx N=1$ supersymmetry in the bulk. Supersymmetry can be broken only on the world brane, a scenario that has been proposed to account for the smallness of the cosmological constant. An interesting prediction from string duality is the generation of a warp factor for conventional type II Calabi--Yau 3-fold compactifications. On the other hand we argue that an assumption that is needed in the RS explanation of the hierarchy is hard to satisfy in the string theory context.
