description: Since stellar populations enhance particular element abundances according to the yields and lifetimes of the stellar progenitors, the chemical evolution of galaxies serves as one of the key tools that allows the tracing of galaxy evolution. In order to deduce the evolution of separate galactic regions one has to account for the dynamics of the interstellar medium, because distant regions can interact by means of large-scale dynamics. To be able to interpret the distributions and ratios of the characteristic elements and their relation to e.g. the galactic gas content, an understanding of the dynamical effects combined with small-scale transitions between the gas phases by evaporation and condensation is essential. In this paper, we address various complex signatures of chemical evolution and present in particular two problems of abundance distributions in different types of galaxies: the discrepancies of metallicity distributions and effective yields in the different regions of our Milky Way and the N/O abundance ratio in dwarf galaxies. These can be solved properly, if the chemodynamical prescription is applied to simulations of galaxy evolution.

description: We explore the validity of vector meson dominance in the radiative decay of the $b_1(1235)$ meson. In order to explain the violation of the vector meson dominance hypothesis in this decay process, we investigate a model where the $b_1$ meson strongly couples with the local current in tensor bilinear representation. The tensor representation is investigated in the framework of the operator product expansion and we found a low energy decay process that does not follow the usual vector meson dominance hypothesis. The $ω$-like intermediate meson state of quantum numbers $I^G(J^{PC}) = 0^{-}(1^{--})$ is found to have a nontrivial role in the decay process of the $b_1$ meson. The spectral structure of the $ω$-like state is found to be close to a $π$-$ρ$ hybrid state, which provides a mechanism that evades the usual vector meson dominance hypothesis. Precise measurements of various decay channels of the $b_1$ meson are, therefore, required to unravel the internal structure of axial vector mesons.

description: We develop a theoretical framework to describe the scattering of photons against a two-level quantum emitter with arbitrary correlated dephasing noise. This is particularly relevant to waveguide-QED setups with solid-state emitters, such as superconducting qubits or quantum dots, which couple to complex dephasing environments in addition to the propagating photons along the waveguide. Combining input-output theory and stochastic methods, we predict the effect of correlated dephasing in single-photon transmission experiments with weak coherent inputs. We discuss homodyne detection and photon counting of the scattered photons and show that both measurements give the modulus and phase of the single-photon transmittance despite the presence of noise and dissipation. In addition, we demonstrate that these spectroscopic measurements contain the same information as standard time-resolved Ramsey interferometry, and thus they can be used to fully characterize the noise correlations without direct access to the emitter. The method is exemplified with paradigmatic correlated dephasing models such as colored Gaussian noise, white noise, telegraph noise, and 1/f-noise, as typically encountered in solid-state environments.

description: We develop technique concerning statistical analyses of the large-scale structure of the universe in the presence of biasing in the structure formation. We formulate the diagrammatic method to calculate the correlation functions of the nonlocally biased field from a generally non-Gaussian density field. Our method is based on generalized Wiener-Hermite expansion of the density field. The present formalism has not only general applicability, but also practical significance, too. To show the effectiveness of this method, we revisit the problems on biasing that have been considered previously, i.e., various approximations for peak statistics and hierarchical structure of correlation functions of locally biased field. Further analyses which have not been possible so far on these problems can be performed by our formalism. The gravitational evolution of primordial fluctuation or other structure-forming processes can be described by nonlocal biasing, so can be treated by our new formalism in principle.

N-Myristoyltransferase as a drug target: a (chemical) space odyssey
Creators: name: Bell, Andy
Publisher: name: Imperial College London
Year: 2015

description: Previous research has provided pre-clinical validation for inhibition of the enzyme N-myristoyltransferase (NMT) target as a novel treatment of fungal and parasitic infections. This thesis describes the discovery of novel NMT inhibitor series derived from high-throughput screens (HTS) of the Pfizer compound collection against NMTs from both Leishmania donovani and Plasmodium falciparum. The further development of two series using structure-based drug design will be discussed, culminating in a series of compounds with efficacy in a mouse malaria model. Following the initial HTS, the hits were triaged based on the orthogonal attributes of structural diversity of each series of analogues; synthetic ease; orthologue selectivity; and estimated ligand efficiency. Iterative screening resulted in a master set that was further triaged through dose-response assays, including selectivity screening against both human NMTs. Eight novel series of NMT inhibitors, half selective for Leishmania and half for Plasmodium NMTs were approved for disclosure by Pfizer. One Leishmania-selective series, based on a thienopyrimidine template, was selected for further development based on a physicochemical hypothesis for achieving cell-based activity. Synthesis of a close analogue of the HTS hit provided validation of the series, which was further developed through the iterative synthesis and testing. The key objective of greatly improved activity in the Leishmania cell-based assays was not achieved. Development of a Plasmodium-selective series of aminomethylindazoles was more successful. Co-crystallisation of a close analogue of the screening hit demonstrated an orthogonal binding mode to the previously published quinoline series. Use of a fragment-linking approach enabled the design and synthesis of novel, highly potent inhibitors with balanced activity against three Plasmodium spp. NMTs, while retaining selectivity over both human NMTs. Excellent translation into cell-based activity was achieved, resulting in several lead compounds with efficacy in a mouse malaria model following both intraperitoneal and oral dosing.
Axial momentum for the relativistic Majorana particle

Year: 2018
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: The Hilbert space of states of the relativistic Majorana particle consists of normalizable bispinors with real components, and the usual momentum operator $- i \nabla$ can not be defined in this space. For this reason, we introduce the axial momentum operator, $ - i γ_5 \nabla$ as a new observable for this particle. In the Heisenberg picture, the axial momentum contains a component which oscillates with the amplitude proportional to $m/E$, where $E$ is the energy and $m$ the mass of the particle. The presence of the oscillations discriminates between the massive and massless Majorana particle. We show how the eigenvectors of the axial momentum, called the axial plane waves, can be used as a basis for obtaining the general solution of the evolution equation, also in the case of free Majorana field. Here a novel feature is a coupling of modes with the opposite momenta, again present only in the case of massive particle or field.

Geometrical and material effects on sensory properties of confectionery wafers and similar extruded products
Creators: name: Butt, Saba Sohail
Publisher: name: Imperial College London
Year: 2016

description: The aim of this research is to determine if products made via the two cooking processes named are producing materials with similar properties thus resulting in a similar consumer perception or whether two fundamentally different products are being obtained. The presented work investigates the correlations between mechanical behaviour, fracture response, microstructure, acoustic emissions and sensory evaluation of a wide range of products made via the extrusion and baking processes. The internal microstructure of the products was examined with a Scanning electron Microscope (SEM). A notable difference between the distributions of the cells was observed between the two products; the wafer comprised of separate skin and core regions with variable pore sizes whereas a more uniform distribution of the pores was present in the extruded products. The mechanical behaviour of both, the extruded and baked, products was characteristic of brittle foam. The extruded products were all found to be stiffer materials in compression when compared to the baked wafers and the extruded products were found to be less anisotropic when compared to baked wafers. Analytical models were used to determine the actual mechanical properties of baked wafer and it was concluded that taking the geometry of the baked wafer into account was essential in finding accurate properties. Sensory, acoustic and mechanical testing results were successfully compared to draw links between the structure-property-texture of the different food products. X-ray Micro tomography (XRT) was used to attain a stack of image slices of the extruded tube architecture which was used to create Finite Element (FE) model of the product volume. Representative Volume Element study was conducted and the ‘crushable foam’ material model was implemented on the FE model to study the microstructure behaviour under compressive loading. The model of the complex architecture was able to predict the deformation behaviour of the extruded product. For future study, the FE models can be used to modify the microstructure to perform parametric studies to quantify the effect of individual geometric variables i.e. pore diameter, on the global response.

The regulatory network controlling Type III Secretion System-mediated pathogenicity in Pseudomonas syringe pv. tomato DC3000
Creators: name: Waite, Christopher James
Publisher: name: Imperial College London
Year: 2015

description: Pseudomonas syringae represents the primary model organism with which the molecular basis of plant-pathogen interactions and co-evolution of host-specificity have been explored. Its virulence is dependent upon the needle-like Type-III secretion system (T3SS) for translocation of effector proteins that interfere with plant defence signalling into the host cell cytoplasm. The sigma factor (σ) HrpL co-ordinates the concomitant transcription of genes encoding the T3SS complex and its associated substrates. In P. syringae, the paralogous activator proteins HrpR and HrpS are both required for σ54-dependent transcription of hrpL. Furthermore, HrpS is subject to allosteric inhibition by HrpV, which is in turn relieved by HrpG. A holistic view of how signalling and regulatory processes control the transition into hrpL-dependent pathogenicity in response to the in planta environment is lacking. In this thesis, I first present evidence for negative autogenous control of the hrpL gene by its σ factor product in the P. syringae pv. tomato DC3000 strain. This novel mechanism is dependent upon HrpL recruiting the bacterial RNA polymerase to the adjacent and divergently transcribed hrpJ promoter. Preliminary in vitro studies suggest that the physical proximity of the RNAP-HrpL holoenzyme complex inhibits at a distance one or more regulatory events required for transcription initiation at hrpL. With respect to its physiological significance, functional analyses infer that the fine control of HrpL expression afforded by negative autogenous control of HrpL expression contributes to correctly ordered T3SS secretion. Secondly, I show that by modulating the activity of the global Gac-Rsm signalling cascade the sensor histidine kinase RetS positively regulates T3SS gene expression as well as affecting other aspects of lifestyle switching. Control of hrpL expression by Gac-Rsm is exerted in part via post-transcriptional regulation of HrpV which, indicative of divergent target specificities, is achieved to varying extents by the three CsrA paralogues in P. syringae.

description: Recent data on CBR anisotropies show a Doppler peak higher than expected in CDM cosmological models, if the spectral index $n=1$. However, CDM and LCDM models with n>1 can hardly be consistent with LSS data. Mixed models, instead, whose transfer function is naturally steeper because of free--streaming in the hot component, may become consistent with data if n>1, when Omega_h is large. This is confirmed by our detailed analysis, extended both to models with a hot component whose momentum space distribution had a thermal origin (like massive neutrinos), and to models with a non--cold component arising from heavier particle decay. In this work we systematically search models which fulfill all constraints which can be implemented at the linear level. We find that a stringent linear constraint arises from fitting the extra-power parameter Gamma. Other significant constraints arise comparing the expected abundances of galaxy clusters and high-z systems with observational data. Keeping to models with Gamma \geq 0.13, a suitable part of the space parameter still allows up to \sim 30% of hot component (it is worth outlining that our stringent criteria allow only models with 0.10 \mincir Omega_h \mincir 0.16, if n \leq 1). We also outline that models with such large non--cold component would ease the solution of the so--called baryon catastrophe in galaxy clusters.

description: The advantages of quantum random number generators (QRNGs) over pseudo-random number generators (PRNGs) are normally attributed to the nature of quantum measurements. This is often seen as implying the superiority of the sequences of bits themselves generated by QRNGs, despite the absence of empirical tests supporting this. Nonetheless, one may expect sequences of bits generated by QRNGs to have properties that pseudo-random sequences do not; indeed, pseudo-random sequences are necessarily computable, a highly nontypical property of sequences. In this paper, we discuss the differences between QRNGs and PRNGs and the challenges involved in certifying the quality of QRNGs theoretically and testing their output experimentally. While QRNGs are often tested with standard suites of statistical tests, such tests are designed for PRNGs and only verify statistical properties of a QRNG, but are insensitive to many supposed advantages of QRNGs. We discuss the ability to test the incomputability and algorithmic complexity of QRNGs. While such properties cannot be directly verified with certainty, we show how one can construct indirect tests that may provide evidence for the incomputability of QRNGs. We use these tests to compare various PRNGs to a QRNG, based on superconducting transmon qutrits and certified by the Kochen-Specker Theorem, to see whether such evidence can be found in practice. While our tests fail to observe a strong advantage of the quantum random sequences due to algorithmic properties, the results are nonetheless informative: some of the test results are ambiguous and require further study, while others highlight difficulties that can guide the development of future tests of algorithmic randomness and incomputability.

Monitoring the hydraulic dynamics in water distribution systems
Creators: name: Hoskins, Asher John
Publisher: name: Imperial College London
Year: 2015

description: Mankind has used pressurised pipes to deliver water over long distances for twenty five centuries and yet the importance of their dynamic hydraulic behaviour on extending the life cycle of critical assets remains poorly understood. This project has developed a novel architecture for collecting, storing, and analysing the dynamic hydraulic behaviour of water distribution systems. This architecture was used to build an extensive collection of dynamic hydraulic pressure recordings which enabled a wide ranging analysis of the effect of pressure transients upon the performance of distribution system assets. A framework, "Dynamic Data Driven Transient Analysis" (D3TA), was developed to detect network state, transient or non-transient flow conditions, to count transients, and to explore the correlation between dynamic hydraulic behaviour and system failures. The effect of calming networks, removing and minimising transient behaviour, was shown to result in a significant potential reduction in bursts. This project has revealed that the hydraulic conditions in distributions systems are rarely steady state and that hydraulic transients are both frequent and potentially damaging. The algorithms and framework developed in this project have the ability to automatically diagnose and identify network areas at risk of damage as a result of their unsteady-state hydraulic behaviour. This would allow water utilities to proactively identify and repair the sources of hydraulic instabilities in operational networks and maintain "calm" networks, thus reducing costs and extending the working lifetimes of network assets. The results show that in some systems a reduction of the dynamic behaviour could result in a significant (10-20%) reduction in bursts.

Influence of sex chromosome complement and hormones on heterochromatin silencing in mice
Creators: name: Silva, Raquel
Publisher: name: Imperial College London
Year: 2015

description: Gender differences are accounted for by sex hormones, autosomal genes, sex-chromosome genes. Previously, the use of sex-reversed mice -hence producing XY females and XX males - revealed that a heterochromatic transgene and 369 autosomal genes in the thymus were differentially expressed dependent on the sex chromosome complement (SCC). These genes were enriched for sensitivity to HP1β dosage. Pericentromeric repeats were also less expressed in XY males when compared to XY gonadectomised/XX males and XY/XX females, suggesting a connection between testosterone, Sry and the Y chromosome. Stemming from the above findings, it was sought to determine: i. if the Y chromosome could enable testosterone to silence heterochromatic repeats ii. whether removal of testosterone affected heterochromatin structure and integrity. Since proximity to heterochromatin had been shown to influence expression of translocated genes and transgenes, the distance of the SCC genes to the nearest annotated major satellite sequence was determined. Twelve predicted protein encoding genes were found embedded in major satellites located near the centromere of chromosome 9. These genes were found to be repressed by testosterone on the XY male, which suggested a potential heterochromatin position effect operating on these endogenous genes which was regulated by sex hormones, tending to equalise their expression between the sexes. Moreover, a trend of increasing number of heterochromatic foci per cell in circulating lymphocytes after gonadectomy of male mice was observed. Together with the upregulation of heterochromatic repeats in the thymus from gonadectomised male mice, suggests that absence of testosterone in males could affect genome stability. Lymphocytes derived from lymph nodes and thymus, showed tissue specificity and dependency on age in the expression of heterochromatic repeats and number of heterochromatic foci per cell. This data has implications for understanding how heterochromatin silencing is regulated between genders and has implications for understanding sex bias genome stability.

description: Quantum Hall matrix models are simple, solvable quantum mechanical systems which capture the physics of certain fractional quantum Hall states. Recently, it was shown that the Hall viscosity can be extracted from the matrix model for Laughlin states. Here we extend this calculation to the matrix models for a class of non-Abelian quantum Hall states. These states, which were previously introduced by Blok and Wen, arise from the conformal blocks of Wess-Zumino-Witten conformal field theory models. We show that the Hall viscosity computed from the matrix model coincides with a result of Read, in which the Hall viscosity is determined in terms of the weights of primary operators of an associated conformal field theory.

The approach incorporates anisotropic fields, non-equilibrium conditions, and non-adiabatic dynamics. By application of a voltage pulse of temporal length $τ$, a recurring $4π$-periodic switching of the localized spin is observed. The switching phenomena can be explained by dynamical exchange interactions, internal transient fields, and self-interactions acting on the localized spin moment.

description: To study the nature of low z Lya absorbers in the spectra of QSOs, we have obtained high signal-to-noise UV spectra of H 1821+643 (z = 0.297) and PG 1116+215 (z = 0.177) with the GHRS on the HST. The spectra have minimum S/N of 70-100 and 3 sigma limiting equivalent widths of 50-75 mA. We detect 26 Lya lines with Wr > 50 mA toward H1821+643 and 13 toward PG1116+215, which implies a density of 102+/-16 lines per unit redshift. The two-point correlation function shows marginal evidence of clustering on ~500 km/s scales, but only if the weakest lines are excluded. We have also used the WIYN Observatory to measure galaxy redshifts in the ~1 degree fields centered on each QSO. We find 17 galaxy-absorber pairs within projected distances of 1 Mpc with velocity separations of 350 km/s or less. Monte Carlo simulations show that if the Lya lines are randomly distributed, the probability of observing this many close pairs is 3.6e-5. We find that all galaxies with projected distances of 600 kpc or less have associated Lya absorbers within 1000 km/s, and the majority of these galaxies have absorbers within 350 km/s. We also find that the Lya equivalent width is anticorrelated with the projected distance of the nearest galaxy out to at least 600 kpc, but this should be interpreted cautiously because there are potential selection biases. Statistical tests using the entire sample also indicate that the absorbers are not randomly distributed. We discuss the nature of the Lya absorbers in light of the new data.

description: We study the low-energy physics of a one-dimensional array of superconducting quantum dots realized by proximity coupling a semiconductor nanowire to multiple superconducting islands separated by narrow uncovered regions. The effective electrostatic potential inside the quantum dots and the uncovered regions can be controlled using potential gates. By performing detailed numerical calculations based on effective tightbinding models, we find that multiple low-energy sub-gap states consisting of partially overlapping Majorana bound states emerge generically in the vicinity of the uncovered regions. Explicit differential conductance calculations show that a robust zero-bias conductance peak is not inconsistent with the presence of such states localized throughout the system, hence the observation of such a peak does not demonstrate the realization of well-separated Majorana zero modes. However, we find that creating effective potential wells in the uncovered regions traps pairs of nearby partially overlapping Majorana bound states, which become less separated and acquire a finite gap that protects the pair of Majorana zero modes localized at the ends of the system. This behavior persists over a significant parameter range, suggesting that proximitized quantum dot arrays could provide a platform for highly controllable Majorana devices.

Influence of early life factors on later ventilatory function: interpreting associations with inflammation, cardiometabolic function and ethnicity

description: Poor ventilatory function, as measured by spirometry, is strongly related to mortality and is the primary characteristic of several chronic lung diseases. This thesis investigates the influence of early life factors, in particular birth weight, on later ventilatory function and elucidates the associations with inflammation, cardiometabolic function and ethnicity. First, I performed a systematic review and meta-analysis on birth weight and ventilatory function. The results provide strong evidence for a positive association of birth weight with forced vital capacity (FVC), a 59.4mL increase in FVC per kg increase in birth weight (95% CI: 43.3 to 75.5). Much weaker evidence was found to support a positive association of birth weight with the ratio of forced expiratory volume in one second to forced vital capacity (FEV1/FVC), particularly among children. Second, I investigated the association of cardiometabolic and inflammatory markers with FVC and FEV1/FVC in young adulthood in the Northern Finland 1966 birth cohort. The associations of inflammatory and cardiometabolic markers differed between FVC and FEV1/FVC, as well as by sex. These associations were strongly influenced by adjustment for important confounders (height and sex) and by mutual adjustment for inflammatory and cardiometabolic markers. These associations were not explained by their common link to low birth weight, nor by socio-economic factors, systemic inflammation or selected prenatal influences, suggesting the involvement of other environmental or genetic factors. Finally, I conducted a pilot investigation on ethnic differences in ventilatory function between White and South Asian British young adults. This study found a reduction of 860 mL (95% CI: -1320 to -400 mL) in FVC among South Asian British, identified parental immigration as an important predictor of FVC, and provided evidence against the hypotheses that differences in birth weight or trunk size can explain ethnic differences in ventilatory function. This study showed the feasibly of similar investigations in larger population-based studies.

ROTATION, DIFFUSION, AND OVERSHOOT IN THE SUN: EFFECTS ON THE OSCILLATION FREQUENCIES AND THE NEUTRINO FLUX

description: We have studied the importance of the combined effects of rotation, diffusion, and convective overshoot on the p-mode oscillation spectrum and the neutrino flux of the standard solar model. To isolate the various physical affects included in the new rotation plus diffusion models we also constructed solar models to test the significance of diffusion and of overshoot by themselves. In previous studies, models that include helium diffusion during solar evolution were found to improve the predicted p-mode frequencies for some modes and worsen the agreement for others (Guenther \ea 1993). Here we verify this result for both the Bahcall and Loeb (1990) formulation of diffusion and the Proffitt and Michaud (1991) formulation of diffusion. We find that the effects of rotation on the Sun's structure in the outer layers perturbs the $p$-mode frequencies only slightly when compared to the more substantial effects due to diffusion. In the thin overshoot layer (taken here to be $0.1\, H_p$), we have compared the effect of overmixing in a radiative layer versus convective (adiabatic) penetration. Neither radiative overmixing nor adiabatic penetration has any significant effect on the $p$-modes, probably in part because the overshoot layer is constrained to be thin. The predicted neutrino flux in our diffusion plus rotation model is 7.12 SNU for Cl detectors, 127 SNU for Ga detectors and $5.00\times 10^6\,{\rm erg \, cm^{-2} }$ for the $^8$B neutrinos; this is approximately half-way between the standard solar model without diffusion, and the standard solar model with diffusion alone.

The impact of maternal antenatal anxiety and depression on child development: examining underlying mechanisms
Creators: name: Capron, Lauren Emma
Publisher: name: Imperial College London

description: Introduction: Maternal antenatal stress/depression is associated with increased risk of offspring emotional and behavioural problems. However, the extent of causality and potential mediating mechanisms are unclear. Objectives: This thesis investigates several questions including: (1)To what extent is the association between maternal antenatal stress/depression and offspring adolescent anxiety causal? (2)Is maternal antenatal stress/depression associated with altered placental gene expression? (3)Is maternal antenatal stress/depression associated with altered infant’s HPA-reactivity/temperament and is this mediated through placental mechanisms? Methods: Two studies were conducted. The first used parental antenatal psychometric measures and offspring anxiety diagnoses at age 18 from the ALSPAC Study. The second study included a cohort of 90-pregnant women. At birth, maternal psychological symptoms and placentae were collected. At 4-months postpartum, mother-infant dyads undertook assessments collecting maternal psychological symptoms and infant behaviour reports. Saliva samples were collected in response to the Still Face Paradigm. Results: In study 1: Maternal antenatal depression was associated with increased risk of offspring anxiety diagnosis(adj.OR1.75(1.19,2.58)). No risk increase was observed with paternal depression. In study 2: Maternal antenatal stress/depression was associated with altered placental gene expression of 11-HSD2 (decrease), MAO-A (decrease) and NR3C1 (increase), but only in Caucasians. Maternal antenatal stress/depression was also associated with increased infant baseline cortisol and HPA-reactivity. Gender-dependent effects on offspring outcome were observed following antenatal depression; females had greater infant HPA-reactivity, males had increased negative temperament. No clear evidence of placenta-mediated effects was observed. Conclusions: This thesis provides new evidence that maternal, but not paternal, antenatal depression is associated with offspring anxiety. Maternal depression/stress was associated with altered placental gene expression but only in Caucasians. This comparison of Caucasian and non-Caucasian participants is a novel finding. Finally, the findings also suggest possible differences by child gender in the associations between maternal antenatal depression/stress and infant outcomes. This requires further exploration in future studies.
