description: Photonic circuits attract much attention as promising candidates to overcome the drawbacks of their electronic counterparts. By utilizing the broad bandwidth and low energy consumption of optical communication, hybrid circuits can provide a comprehensive platform for the era beyond Moore's law. In particular, parallel matrix operations, the heavy lifting behind neural networks, remain challenging for traditional electronics due to high heat dissipation. To enable these parallel computations optically, (de-)multiplexing is crucial to address the different channels. Previously this has been accomplished with complex spectral or time encodings in wave division or time division methods. However, herein, a simple method to address parallel optical channels exclusively with 2-bit signals is presented. By using PEDOT:PSS as electrochromic material for intensity modulation, light transmission or absorption is controlled by oxidation and reduction with an electrolyte. Y-branch structures are used to design the multiplexing layout and to assign the 2-bit states to the channels. This binary addressable optical multiplexer, therefore, combines optical communication with electronic signals into a hybrid circuit.

description: The boron nitride nanomesh is a corrugated monolayer of hexagonal boron nitride (h-BN) on Rh(111), which so far has been studied mostly under ultrahigh vacuum conditions. Here, we investigate how copper underpotential deposition (upd) can be used to quantify defects in the boron nitride monolayer and to assess the potential window of the nanomesh, which is important to explore its functionality under ambient and electrochemical conditions. In dilute sulfuric acid, the potential window of h-BN/Rh(111) is close to 1 volt, i.e. larger than that of the Rh substrate, and is limited by molecular hydrogen evolution on the negative and by oxidative removal on the positive side. From copper upd on pristine h-BN/Rh(111) wafer samples, we estimate a collective defect fraction on the order of 0.08-0.7% of the geometric area, which may arise from line and point defects in the h-BN layer that are created during its chemical vapour deposition. Overpotential deposition (opd) is demonstrated to have significant consequences on the defect area. We hypothesise that this non-innocent Cu electrodeposition involves intercalation originating at initial defects, causing irreversible delamination of the h-BN layer; this effect may be used for 2D material nanoengineering. On the relevant timescale, upd itself does not alter the defect area on repeated cycling; therefore, metal upd may find use as a general tool to determine the collective defect area in hybrids between 2D materials and various substrate metals.

description: In energetic heavy ion collisions, if quark-gluon plasma is formed, its hadronization may lead to observable critical fluctuations, i.e., DCC formation. The strength and observability of these fluctuations depend on the initial state. Here we study the canonical ensemble of initial states of chiral fluctuations in heavy ion collisions and the probability to obtain observable domains of chiral condensates.

description: We study the transfer of energy through a network of coupled oscillators, which represents a minimalmicroscopic power grid connecting multiple active quantum machines. We evaluate the resulting energy currentsin the macroscopic, thermal, and quantum regime and describe how transport is affected by the competitionbetween coherent and incoherent processes and nonlinear saturation effects. Specifically, we show that thetransfer of energy through such networks is strongly influenced by a nonequilibrium phase transition between anoise-dominated and a coherent transport regime. This transition is associated with the formation and breakingof spatial symmetries and is identified as a generic feature of active networks. Therefore, these findings haveimportant practical consequences for the distribution of energy over coherent microwave, optical, or phononicchannels, in particular close to or at the quantum limit

Covariantising the Beltrami equation in W-gravity

Year: 1995
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Recently, certain higher dimensional complex manifolds were obtained in [hep-th/9412078] by associating a higher dimensional uniformisation to the generalised Teichmüller spaces of Hitchin. The extra dimensions are provided by the ``times'' of the generalised KdV hierarchy. In this paper, we complete the proof that these manifolds provide the analog of superspace for W-gravity and that W-symmetry linearises on these spaces. This is done by explicitly constructing the relationship between the Beltrami differentials which naturally occur in the higher dimensional manifolds and the Beltrami differentials which occur in W-gravity. This also resolves an old puzzle regarding the relationship between KdV flows and W-diffeomorphisms.

Characterization of a stem cell population derived from human peripheral blood and its therapeutic potential in brain tumors
Creators: name: Flores, Catherine
Publisher: name: Imperial College London
Year: 2009

description: Adherent CD34+ cells are a stem cell enriched population with a high frequency of primitive stem cells that are genetically primed to differentiate into tissue-specific lineages. These cells make up the adherent CD34+ cells in peripheral blood which are the focus of this study. The first aim of this study was to transcriptionally characterize adherent CD34+ cells relative to nonadherent CD34+ cells using a whole human genome Affymetrix U133 plus 2 array. The subsequent analysis demonstrated transcriptional differences in genes which are involved in quiescence, cell cycle, homing and adhesion, which are likely to be relevant to the suitability of adherent CD34+ cells for clinical application. To verify the microarray analysis, a selection of representative transcripts was chosen and their relative expression was compared using real-time qPCR. To analyze further the stem cell characteristics of adherent CD34+ cells, the DNA replication timing kinetics of pluripotency-associated genes in bone marrow-derived adherent CD34+ cells, non-adherent CD34+ cells, and foetal mesenchymal stem cells were conducted and compared to those of embryonic stem (ES) cells. This showed that pluripotency-associated genes Oct4 and Nanog replicate early in the cell cycle similar to ES cells. The second aim of this study was to examine the potential use of adherent CD34+ cells in neural injury. As adherent CD34+ cells are primitive stem cells, it was reasonable to hypothesize that these cells would differentiate into neural cells in vitro, but these experiments revealed that these cells are not neurogenic and, in our hands, do not differentiate into neural cells. The experiments revealed that adherent CD34+ cells differentiate efficiently and reproducibly into microglia-like cells (CD34MG cells). CD34MG cells upregulated microglia-associated antigens and demonstrated functional characteristics of microglia cells including TNF and IL-6 release in response to lipopolysaccharide. CD34MG also stimulate responders in a mixed lymphocyte reaction, suggesting antigen presenting capabilities. To determine if these cells might be exploited for use in brain tumour therapy, it was shown that CD34MG migrate and invade in response to brain tumour glioma cells. Results also suggest that these cells are capable of presenting glioma specific antigen to immune cells in an autologous lymphocyte reaction in vitro. The combined results suggest that CD34MG cells might be exploited for therapeutic purposes in brain tumours. Stem cells are currently being explored for their therapeutic potential. This study demonstrates that adherent CD34+ cells and CD34MG cells may be useful for clinical use.
Segmentation and Deformable Modelling Techniques for a Virtual Reality Surgical Simulator in Hepatic Oncology
Creators: name: Chi, Ying
Publisher: name: Imperial College London
Year: 2008

description: Liver surgical resection is one of the most frequently used curative therapies. However, resectability is problematic. There is a need for a computer-assisted surgical planning and simulation system which can accurately and efficiently simulate the liver, vessels and tumours in actual patients. The present project describes the development of these core segmentation and deformable modelling techniques. For precise detection of irregularly shaped areas with indistinct boundaries, the segmentation incorporated active contours - gradient vector flow (GVF) snakes and level sets. To improve efficiency, a chessboard distance transform was used to replace part of the GVF effort. To automatically initialize the liver volume detection process, a rotating template was introduced to locate the starting slice. For shape maintenance during the segmentation process, a simplified object shape learning step was introduced to avoid occasional significant errors. Skeletonization with fuzzy connectedness was used for vessel segmentation. To achieve real-time interactivity, the deformation regime of this system was based on a single-organ mass-spring system (MSS), which introduced an on-the-fly local mesh refinement to raise the deformation accuracy and the mesh control quality. This method was now extended to a multiple soft-tissue constraint system, by supplementing it with an adaptive constraint mesh generation. A mesh quality measure was tailored based on a wide comparison of classic measures. Adjustable feature and parameter settings were thus provided, to make tissues of interest distinct from adjacent structures, keeping the mesh suitable for on-line topological transformation and deformation. More than 20 actual patient CT and 2 magnetic resonance imaging (MRI) liver datasets were tested to evaluate the performance of the segmentation method. Instrument manipulations of probing, grasping, and simple cutting were successfully simulated on deformable constraint liver tissue models. This project was implemented in conjunction with the Division of Surgery, Hammersmith Hospital, London; the preliminary reality effect was judged satisfactory by the consultant hepatic surgeon.

description: We give a detailed general description of a recent geometrical discretisation scheme and illustrate, by explicit numerical calculation, the scheme's ability to capture topological features. The scheme is applied to the Abelian Chern-Simons theory and leads, after a necessary field doubling, to an expression for the discrete partition function in terms of untwisted Reidemeister torsion and of various triangulation dependent factors. The discrete partition function is evaluated computationally for various triangulations of $S^3$ and of lens spaces. The results confirm that the discretisation scheme is triangulation independent and coincides with the continuum partition function

We show that the vacuum fluctuation effect on the nucleon effective mass is more important than the direct coupling between the Fermi sea and the Dirac sea due to the pairing interaction. The effects of the high-momentum cutoff are also discussed.

Using this representation, we calculate 1,2,3,4 bodies interactions and the free energies for $N =3,4,5$ numerically and find that in fact the multi-instanton interaction effect essentially contribute to the large N phase transition discovered by Douglas and Kazakov.

description: Given a finite group $G$, we denote by $ψ\,'(G)$ the product of element orders of $G$. Our main result proves that the restriction of $ψ\,'$ to abelian $p$-groups of order $p^n$ is strictly increasing with respect to a natural order on the groups relating to the lexicographic order of the partitions of $n$. In particular, we infer that two finite abelian groups of the same order are isomorphic if and only if they have the same product of element orders.

Dentro de los resultados más relevantes expuestos en el documento, se resalta que la transformación que se plantea en el PND, evidenciada en una serie de estrategias transformadoras en materia de seguridad y convivencia ciudadana, no tiene realmente un componente transformador tan claro; sin embargo, basado en la noción de seguridad humana expuesta por el gobierno, el plan prioriza la protección y la prevención sobre todo lo demás, dándole así un mayor peso a la convivencia sobre la seguridad.
Functional analysis of Methanocaldococcus jannaschii RNA polymerase A’ ‘bridge-helix’ using a fully automated high-throughput robotic system
Creators: name: Tan, Lin
Publisher: name: Imperial College London
Year: 2009

description: RNA polymerases (RNAPs) are the ‘engines’ of cellular transcriptional machineries, which are essential to life and highly conserved from bacteria to eukaryotes. Though crystal structures of both eukaryotic and bacterial RNAPs have been intensively studied, the relationships between structures and appropriate functions of such enzymes in eukaryotes remain unknown since there has not yet been possible to constitute any active eukaryotic RNAPs from recombinant subunits. The successfully assembled archaeal counterparts have provided an alternative approach to study the eukaryotic system due to not only the structural similarities between these enzymes but also the structural and functional similarities of their basal transcriptional machineries. ‘Bridge-helix’ is one of the most highly conserved structures near the catalytic site of RNAPs, which has been proposed to play an important role in coordinating the processing of nucleic acid substrates through the active center. 17 adjacent residues (mjA’-L814 to mjA’-R830) within the central portion of Methanocaldococcus jannaschii A’ ‘bridge-helix’ were chosen for a systematic high-throughput sitedirected mutagenesis approach using a novel robotic system. This robotic system is fully automated without any human interventions that may enormously reduce human errors and effectively increase the number of samples that could be processed in parallel. The results obtained from such high-throughput approach showed a wide spectrum of in vitro phenotypes ranging from complete loss of function to ‘superactivity’. According to the unexpected functional evidences obtained with the ‘superactive’ mutants, we propose a highly favorable kinked ‘bridge-helix’ conformation for the nucleotide addition cycle that has to be precisely localized in certain positions in order to increase the specific activity of RNAPs. The fact that no additive effects have been found so far in any of the ‘superactive’ double mutants suggests that various single amino-acid substitution ‘superactive’ mutants may affect the same process in a functionally overlapping and mutually independent manner.

Primiarily the reason for this is the bio-compatability of the devices and this refers to both the devices’ compatibility with the culture as well as its compatibility with the device. Glucose sensors fabricated in electropolymerised poly(phenol) were used for the study. The reproducibility of these devices was checked to assess their viability for large scale deployment. It was found that the intra–batch variation was within the norms of experimental error, although the inter–batch variation was significant. This is a feature that is inherent to hand made devices and some methods to mitigate this are discussed. The surface characterisation of the sensors showed that the polymer and enzyme sit mutually exclusive to each other on the surface. Using cyclic voltammetry, with ferrocyanide as the probe molecule, it was confirmed that the diffusion profile to the surface of the sensor was semi-infinite planar and that the electrochemistry was quasi-reversible. Infra–red and Raman spectroscopy and scanning electrochemical microscopy were used as well to study the films’ morphology. The sensors were not toxic to 3T3 cell cultures, as the yield and cell viability were consistent with those of the control cultures. It was also seen that the initial degradation of the sensors’ response was not entirely due to the loss in enzyme activity. Non-polarised sensors showed a decrease in sensitivity to glucose and a threshold concentration ca. 3 mM below which they showed no response to glucose, when they were removed from the culture. These effects were not seen before the sensors were placed in the culture and in protein free media, they were partially reversed over time.
Investigation of the novel proteins of Influenza B
Creators: name: Elderfield, Ruth Alice
Publisher: name: Imperial College London

description: Influenza B viruses encode two small proteins, NB and BM2. BM2 is translated from segment 7 mRNAs by a mechanism involving sequence complementarity to the 18S ribosomal subunit. The importance of these complementary sequences was tested in the context of infectious virus using a reverse genetic approach. A series of mutations were introduced into this region of segment 7. Recombinant viruses with disrupted 18S complementarity displayed deficiency in BM2 expression in infected cells. The BM2 protein is essential for virus replication because its ion channel activity is required during virion entry to the cell. There is also evidence that the cytoplasmic tail of BM2 is involved in viral assembly. A series of amino acid truncations and substitutions in the BM2 cytoplasmic tail were engineered. Recombinant viruses that lacked more than 5 residues at the carboxyl terminus of the protein were not recovered and key residues in the region -5 to -10 were identified. The influenza B virus RNA segment 6 encodes the neuraminidase protein, NA, as well as NB. NB is a 100 amino acid transmembrane protein with a glycosylated ectodomain. NB is conserved in all natural influenza B virus isolates. Influenza B viruses that lack the NB protein can replicate in cell culture to wild-type levels, However, the deletant viruses showed attenuated growth in complex airway cultures derived from humans and ferrets. In vivo, infected ferrets excreted infectious virus in the nasal wash one day later than for viruses that encode NB. Alterations in the expression of the NA protein were not responsible for the attenuated phenotype shown by NB deletant viruses. The role of the host cell ESCRT pathway or of the interferon-induced tetherin protein in assembly and release of influenza viruses was assessed. No evidence was found for either host pathway in the replication of influenza viruses.

Protein complexes in base excision repair: Biochemical and kinetic analysis of mismatch uracil DNA glycosylase
Creators: name: Grippon, Ayse Seden
Publisher: name: Imperial College London
Year: 2010

description: Mismatch uracil DNA glycosylase (MUG) is an E. coli enzyme involved in the repair of ethenocytosine and uracil through the base excision repair pathway. MUG is known to bind the abasic site tightly. This may act to protect the abasic lesion, but the question then is how is the site handed over to the AP Endonuclease? Much has been made of the increase in turnover of some DNA glycosylases by AP endonucleases, but it is not clear whether this occurs via an active displacement mechanism or by passive diffusion. We are addressing these questions by studying the kinetics of MUG interactions with its product and Exonuclease III, the main AP Endonuclease in E. coli. We used fluorescence anisotropy and fluorescence resonance energy transfer assays to investigate MUG & DNA interactions. These revealed that MUG binds abasic DNA in a cooperative manner and that binding of two MUG‘s is needed for efficient DNA repair. Higher salt concentrations reduced cooperativity leading to a 1:1 binding and reduced MUG‘s activity. We also used these assays to investigate whether ExoIII displaces MUG from the DNA through an active or passive mechanism. MUG‘s role in the in vivo repair of etheno lesions has been explored by treating E. coli cells with urethane, a chemical, known to introduce etheno lesions in the DNA. A eukaryotic DNA glycosylase, hSMUG was shown to repair etheno lesions; hence we investigated hSMUG‘s ability to complement mug deficiency in E. coli cells. hSMUG was found to reduce cell viability, increase mutation rates and provided a boost in cell divisions in mug deficient cells whereas it didn‘t affect wild type cells. We then asked the question whether hAPE1, the AP endonuclease believed to increase the turnover rate of hSMUG, can reverse the effects of hSMUG expression in E. coli.

Repeatability Corner Cases in Document Ranking: The Impact of Score Ties

description: Document ranking experiments should be repeatable. However, the interaction between multi-threaded indexing and score ties during retrieval may yield non-deterministic rankings, making repeatability not as trivial as one might imagine. In the context of the open-source Lucene search engine, score ties are broken by internal document ids, which are assigned at index time. Due to multi-threaded indexing, which makes experimentation with large modern document collections practical, internal document ids are not assigned consistently between different index instances of the same collection, and thus score ties are broken unpredictably. This short paper examines the effectiveness impact of such score ties, quantifying the variability that can be attributed to this phenomenon. The obvious solution to this non-determinism and to ensure repeatable document ranking is to break score ties using external collection document ids. This approach, however, comes with measurable efficiency costs due to the necessity of consulting external identifiers during query evaluation.

Aspects of the ecology of macaroni penguins (Eudyptes chrysolophus) around South Georgia
Creators: name: Hart, Tom
Publisher: name: Imperial College London
Year: 2009

description: Macaroni penguins (Eudyptes chrysolophus Brandt) feed when diving during long foraging trips away from their breeding colony. Their foraging behaviour is constrained by a number of factors including their physiology, their condition, the condition of their partner, and the condition of their chick. This thesis concerns aspects of their foraging ecology in relation to prey availability. Time Depth Recorders and other archival tags are increasing in their capacity, battery life and durability at the same time as getting cheaper and smaller and are frequently used to explore foraging behaviour. However, development and application of techniques to analyse these resulting data sets lags behind our ability to collect the data. This thesis develops new methods and uses data from 129 macaroni penguins collected over 6 years to determine patterns of foraging behaviour. In particular: 1. Appropriate identification of sex is essential to any study of foraging ecology, in particular during the breeding season. In response to an identified problem with morphometric sexing, I conduct a validation test between molecular and morphometric sex tests and make conclusions about the nature and identity of error in these tests. 2. I use summary statistics to characterise dives. This work suggests that time series techniques may provide insights that have been lacking from previous analyses. I apply time series techniques to the data to model non-independence in data sets and to compare results obtained using auto-correlation methods with findings obtained from (1) above. The time series approach allows a comparison of different temporal elements of dives, in particular correlations between features of successive dives and how correlation between dives decays with time. 3. I use Hidden Markov Models as a clustering algorithm to provide a statistically robust description of patterns in dives that may outperform the widely used concept of bouts of dives. I then use this method to determine whether such clustering of dives exists in my data. Characteristics of bouts and types of dives vary with year, the stage and sex of the individual. 4. Hidden Markov Models do not provide a direct replacement for the concept of bouts. Rather than identify bouts as summary statistics of diving activity, I take daily summaries of activity. I then use these to overcome the nonindependence of dives and to determine the relative periods of dive activity and travel or searching. Comparison between the adult and chick fledging weights revealed a strategy of investment in the chick at the expense of the adult body mass. The application of time series techniques has led to new insights about the timing of decision-making, but this thesis reveals that further advances also require positional data to be combined with temporal activity data.

description: We examine the necessity of requiring that relaxion dynamics is dominated by classical slow roll and not quantum fluctuations. It has been recently proposed by Nelson and Prescod-Weinstein that abandoning this requirement can lead to a unified solution of the hierarchy and strong CP problems in QCD relaxion models. In more general models this results in a higher value of the allowed cut-off. In this work we find, however, that relaxing this condition and can result in the universe being dominated in physical volume by regions arising from large quantum fluctuations of the relaxion. These regions turn out to be problematic for the relaxion mechanism because either the relaxion does not stabilise at all or it stabilises at vacua which cannot reproduce the observed properties of our universe. The size of these undesirable regions is moreover ambiguous because of the measure problem. For instance, we show that if one chooses to use the scale factor cut-off measure such dangerous regions occupy a negligible volume and these issues do not arise.

description: We show how event topology classification based on deep learning could be used to improve the purity of data samples selected in real time at at the Large Hadron Collider. We consider different data representations, on which different kinds of multi-class classifiers are trained. Both raw data and high-level features are utilized. In the considered examples, a filter based on the classifier's score can be trained to retain ~99% of the interesting events and reduce the false-positive rate by as much as one order of magnitude for certain background processes. By operating such a filter as part of the online event selection infrastructure of the LHC experiments, one could benefit from a more flexible and inclusive selection strategy while reducing the amount of downstream resources wasted in processing false positives. The saved resources could be translated into a reduction of the detector operation cost or into an effective increase of storage and processing capabilities, which could be reinvested to extend the physics reach of the LHC experiments.
