description: Although the tremendous catalytic power of enzymes is widely recognized, their exact mechanisms of action are still a source of debate. In order to elucidate the origin of their power, it is necessary to look at individual residues and atoms, and establish their contribution to ligand binding, activation, and reaction. Given the present limitations of experimental techniques, only computational tools allow for such detailed analysis. During my PhD studies I have applied a variety of computational methods, reviewed in Chapter 2, to the study of two enzymes: DfrB dihydrofolate reductase (DHFR) and methyltetrahydrofolate: corrinoid/iron-sulfur protein methyltransferase (MeTr).

description: Objective: To determine whether selected metabolic factors are associated with greater amounts of radiographic hand osteoarthritis (OA) incidence and progression. Methods: The study identified 706 adults, aged 50–69 years, with hand pain and hand radiographs at baseline, from two population-based cohorts. Metabolic factors (body mass index, hypertension, dyslipidaemia, and diabetes) were ascertained at baseline by direct measurement and medical records. Analyses were undertaken following multiple imputation of missing data, and in complete cases (sensitivity analyses). Multivariable regression models estimated associations between metabolic factors and two measures of radiographic change at 7 years for all participants, individuals free of baseline radiographic OA, and in baseline hand OA subsets. Estimates were adjusted for baseline values and other covariates. Results: The most consistent and strong associations observed were between the presence of diabetes and the amount of radiographic progression in individuals with nodal OA [adjusted mean differences in Kellgren–Lawrence summed score of 4.50 (−0.26, 9.25)], generalized OA [3.27 (−2.89, 9.42)], and erosive OA [3.05 (−13.56, 19.67)]. The remaining associations were generally weak or inconsistent, although numbers were limited for analyses of incident radiographic OA and erosive OA in particular. Conclusion: Overall metabolic risk factors were not independently or collectively associated with greater amounts of radiographic hand OA incidence or progression over 7 years, but diabetes was associated with radiographic progression in nodal, and possibly generalized and erosive OA. Diabetes has previously been associated with prevalent but not incident hand OA. Further investigation in hand OA subsets using objective measures accounting for disease duration and control is warranted.

A Stability Analysis for the Acceleration-based Robust Position Control of Robot Manipulators via Disturbance Observer

description: This paper proposes a new nonlinear stability analysis for the acceleration-based robust position control of robot manipulators by using Disturbance Observer (DOb). It is shown that if the nominal inertia matrix is properly tuned in the design of DOb, then the position error asymptotically goes to zero in regulation control and is uniformly ultimately bounded in trajectory tracking control. As the bandwidth of DOb and the nominal inertia matrix are increased, the bound of error shrinks, i.e., the robust stability and performance of the position control system are improved. However, neither the bandwidth of DOb nor the nominal inertia matrix can be freely increased due to practical design constraints, e.g., the robust position controller becomes more noise sensitive when they are increased. The proposed stability analysis provides insights regarding the dynamic behavior of DOb-based robust motion control systems. It is theoretically and experimentally proved that non-diagonal elements of the nominal inertia matrix are useful to improve the stability and adjust the trade-off between the robustness and noise sensitivity. The validity of the proposal is verified by simulation and experimental results.

Appreciations and Audience Response in 4 Mexican Political Speeches

description: Using the fine-grained methodology of Conversation Analysis, the video recordings of four political speeches delivered by a Mexican Governor were examined. Since previous studies have found that speakers design sequences of talk to elicit the audience’s applause (Atkinson, 1984a, 1984b; Bull, 2003; Heritage and Greatbatch, 1986), the departure point for this thesis was to find where applause occurred in order to examine what sequences of talk elicited it. A preliminary observation was that every time the Governor expressed appreciation to a person or group of people, the audience applauded and the recipients non-verbally responded to the Governor for the appreciation. A detailed examination of the structure, the sequence organisation and the delivery of ‘appreciations’ was carried out. At a structural level it was found that by changing footing, thus affecting the audience and the recipient’s participation framework, the Governor was able to move from addressing the audience to addressing the recipient of his appreciation and back to the audience to re-commence his monologic talk. At the sequence organisation level, it was found that the actions performed by the Governor and by the addressed-recipient of his appreciation constitute an adjacency pair (AP): not until the Governor finishes doing appreciation do the recipients respond to the Governor for the appreciation. The audience’s applause, on the other hand, can neither be said to be part of the main AP nor be said to perform a straightforward action. Instead, the audience’s applause is a continuous action, enveloping, through clapping, the whole appreciation. At the delivery level, it was examined and explained how the Governor combines intonation, gaze and body movements with his words to elicit the audience and the recipients’ responses. Though a detailed examination and explication of the actions performed by the Governor, the audience, and the recipients of appreciations, this thesis is able to show how a particular moment of interaction within the monologic format of four Mexican political speeches is created, sustained and brought to a closure. This thesis is also able to demonstrate that the speeches under examination differ in their organisation from other political speeches, and consequently, from prior findings (e.g. Atkinson 1984a, 1984b; Bull, 2003; Heritage and Greatbatch, 1986).

description: We present the first results of a spectroscopic survey of Lyman break galaxies in the near-infrared aimed at detecting the emission lines of [O II], [O III], and Hbeta from the H II regions of star forming galaxies at z = 3. From observations of 19 objects with the Keck and VLT telescopes, we reach the following main conclusions. Contrary to expectations, the star formation rates deduced from the Hbeta luminosity are on average no larger than those implied by the stellar continuum at 1500 A; presumably any differential extinction between rest-frame optical and UV is small compared with the relative uncertainties in the calibrations of these two star formation tracers. For the galaxies in our sample, the abundance of O can only be determined to within one order of magnitude. Even so, it seems well established that LBGs are the most metal-enriched structures at z = 3, apart from QSOs, with abundances greater than about 1/10 solar. They are also significantly overluminous for their metallicities; this is probably an indication that their mass-to-light ratios are small compared with present-day galaxies. At face value their velocity dispersions, sigma = 50 - 115 km/s imply virial masses of about 10^{10} solar masses within half-light radii of 2.5 kpc. However, we are unable to establish if the widths of the emission lines do reflect the motions of the H II regions within the gravitational potential of the galaxies, even though in two cases we see hints of rotation curves. All 19 LBGs observed show evidence for galactic-scale superwinds; such outflows are important for regulating star formation, distributing metals over large volumes, and allowing Lyman continuum photons to escape and ionize the IGM.

description: The Tasmanian dolerites were intruded into essentially flat-lying Permian and Triassic sediments in the form of sheets, commonly exceeding 1000 feet in thickness, large dyke-like intrusions up to one mile in width, and transgressive bodies. The dolerite is post Triassic and pre-Tertiary in age, and Hills and Carey (194-9, 54-) and Banks (1958, 234-) suggest that the intrusions took place in the Jurassic. They crop out over more than 6,000 square miles, and Edwards (1942, 452) has estimated that the volume of magma intruded was of the order of 3,000 cubic miles. (First paragraph of Introduction).

description: This thesis is concerned with certain aspects of the genetic behaviour of a zoological or botanical population. Broadly speaking, the models used here to describe populations are 'natural', in the sense that they subject the individuals to mainly random influences, as opposed to the controlled environments such as poultry and many vegetable crops. The aim is to discover the evolutionary significance of these random influences by the application of probability theory; an analysis is made of the possible states of the population after a considerable number of generations has elapsed from some initial instant.

description: We study the long time behavior of the zz and xx time dependent autocorrelation function of the spin 1/2 XXZ chain at $T=\infty$ by exact diagonalizations on a chain of 16 sites. We find that the numerical results for the zz correlation are very well fit by the formula $t^{-d}[A+Be^{-γ(t-t_0)}\cos Ω(t-t_0)].$ From this we estimate $d$ as a function of the anisotropy of the chain and study the crossover from ballistic to diffusive behavior.

A 4D Filtering and Calibration Technique for Small-Scale Point Cloud Change Detection with a Terrestrial Laser Scanner

This study presents a point cloud de-noising and calibration approach that takes advantage of point redundancy in both space and time (4D). The purpose is to detect displacements using terrestrial laser scanner data at the sub-mm scale or smaller, similar to radar systems, for the study of very small natural changes, i.e., pre-failure deformation in rock slopes, small-scale failures or talus flux. The algorithm calculates distances using a multi-scale normal distance approach and uses a set of calibration point clouds to remove systematic errors. The median is used to filter distance values for a neighbourhood in space and time to reduce random type errors. The use of space and time neighbours does need to be optimized to the signal being studied, in order to avoid smoothing in either spatial or temporal domains. This is demonstrated in the application of the algorithm to synthetic and experimental case examples. Optimum combinations of space and time neighbours in practical applications can lead to an improvement of an order or two of magnitude in the level of detection for change, which will greatly improve our ability to detect small changes in many disciplines, such as rock slope pre-failure deformation, deformation in civil infrastructure and small-scale geomorphological change.

description: Yuwaalaraay and Gamilaraay are closely related languages from the North of New South Wales which had dramatically declined in use and are now being reused by many Yuwaalaraay Gamilaraay people in a variety of ways. This thesis expands the grammatical description of the languages, building in particular on Williams (1980). A wide range of sources from the mid-19th century to the tapes made in the 1970s are examined. Light is shed on them by the growing body of typology of Pama-Nyungan languages and in particular by Donaldson’s (1980) Grammar of Wangaaybuwan, which along with Gamilaraay, Yuwaalaraay, Wayilwan and Wiradjuri form the Central New South Wales language sub-group. The main topics covered are nominal morphology (Chapters 2-6), verbal morphology (Chapters 7-9) and syntax (Chapters 10-11). Chapter 8 covers interrogatives, negatives, indefinites and ignoratives. Notable features of nominals include the complex, and not yet fully described, set of demonstratives. YG verbs have a wide range of stem forming suffixes, including distinctive Time of Day suffixes (morning, afternoon and night), and Distance in Time suffixes which subdivide the past and future. Included is the first description of the middle verb forms, which have a range of case frames. Where possible the grammar of the languages is described, with extensive evidence from the sources. Often there is currently unanalysable material, and this is often included, providing a starting point for further work on the languages. The thesis has an appendix, which contains background YG material and material from other languages. There is also a resource disc which has transcriptions of many of the source documents and tapes.

description: Neural networks promise to bring robust, quantitative analysis to medical fields, but adoption is limited by the technicalities of training these networks. To address this translation gap between medical researchers and neural networks in the field of pathology, we have created an intuitive interface which utilizes the commonly used whole slide image (WSI) viewer, Aperio ImageScope (Leica Biosystems Imaging, Inc.), for the annotation and display of neural network predictions on WSIs. Leveraging this, we propose the use of a human-in-the-loop strategy to reduce the burden of WSI annotation. We track network performance improvements as a function of iteration and quantify the use of this pipeline for the segmentation of renal histologic findings on WSIs. More specifically, we present network performance when applied to segmentation of renal micro compartments, and demonstrate multi-class segmentation in human and mouse renal tissue slides. Finally, to show the adaptability of this technique to other medical imaging fields, we demonstrate its ability to iteratively segment human prostate glands from radiology imaging data.

description: It has been observed that in bulk and polycrystalline thin films of collossal magnetoresistive (CMR) materials the magnetoresistance follows a different behaviour compared to single crystals or single crystalline films below the ferromagnetic transition temperature Tc. In this paper we develop a phenomenological model to explain the magnetic field dependence of resistance in granular CMR materials taking into account the spin polarised tunnelling at the grain boundaries. The model has been fitted to two systems, namely, La0.55Ho0.15Sr0.3MnO3 and La1.8Y0.5Ca0.7Mn2O7. From the fitted result we have separated out, in La0.55Ho0.15Sr0.3MnO3, the intrinsic contribution from the intergranular contribution to the magnetoresistance coming from spin polarised tunnelling at the grain boundaries. It is observed that the temperature dependence of the intrinsic contribution to the magnetoresistance in La0.55Ho0.15Sr0.3MnO3 follows the prediction of double exchange model for all values of field.

description: We consider the entropy of a quantum scalar field on a background black hole geometry in asymptotically anti-de Sitter space-time, using the ``brick wall'' approach. In anti-de Sitter space, the theory has no infra-red divergences, and all ultra-violet divergences can be absorbed into a renormalization of the coupling constants in the one-loop effective gravitational Lagrangian. We then calculate the finite renormalized entropy for the Schwarzschild-anti-de Sitter and extremal Reissner-Nordstrom-anti-de Sitter black holes, and show that, at least for large black holes, the entropy is entirely accounted for by the one-loop Lagrangian, apart possibly from terms proportional to the logarithm of the event horizon radius. For small black holes, there are indications that non-perturbative quantum gravity effects become important.

description: A hallmark of a thermodynamic phase transition is the qualitative change of system thermodynamic properties such as energy and heat capacity. On the other hand, no phase transition is thought to operate in the supercritical state of matter and, for this reason, it was believed that supercritical thermodynamic properties vary smoothly and without any qualitative changes. Here, we perform extensive molecular dynamics simulations in a wide temperature range and find that a deeply supercritical state is thermodynamically heterogeneous, as witnessed by different temperature dependence of energy, heat capacity and its derivatives at low and high temperature. The evidence comes from three different methods of analysis, two of which are model-independent. We propose a new definition of the relative width of the thermodynamic crossover and calculate it to be in the fairly narrow relative range of 13-20\%. On the basis of our results, we relate the crossover to the supercritical Frenkel line.

description: Micro-pillars with diameters varying from 0.5 to 3.5 µm were fabricated from bulk nanolaminated graphene (in the form of reduced grapheme oxide, RGO)–Al composite. Upon uniaxial compression, the pillar strengths exhibited no obvious size effect, and the pillars of larger diameters possessed smoother stress–strain response, as opposed to the jerky deformation of their smaller counterparts. A corresponding transition in the deformation mode from Al layer extrusion to shear fracture over decreasing pillar diameter was observed. These observations were explained by the competing effect of dislocation accumulation and annihilation, and a grain boundary-assisted deformation mechanism. IMPACT STATEMENT The transition in the deformation mode of graphene–Al composite micro-pillars from localized shear facture to Al layer extrusion over increasing pillar diameter is attributed to a grain boundary-assisted deformation mechanism.

description: The universal behavior of the continuous superconducting (glass) phase transition is studied in a YBa$_2$Cu$_3$O$_{7-δ}$ thin film. A new analysis technique for extracting critical exponents is developed, using current-voltage ($J$-$E$) measurements. The method places narrow limits on the glass scaling exponents, $z_g$ and $ν_g$, as well as the glass transition temperature, $T_g(H)$. The universal values $z_g = 3.8\pm 0.2$ and $ν_g = 1.8\pm 0.1$ are obtained. Using these values, the data are scaled for fields in the range 1-9~T. Collapse of the scaling forms at different fields describes the universal scaling function. The field dependence of the universal collapse is interpreted in terms of the 3D~XY multicritical scaling theory.

The SL magnetization might be experimentally measurable, and the magnetic susceptibility diverges as $|B_\parallel - B_{c}|^{-1}$.

description: This work proposes a sequential optimization algorithm, EORKS, combining a Kriging surrogate from an adaptive sampling and an iterative constrained search in the dynamic reliable regions to reduce the sampling size in expensive optimization. A surrogate established from small samples is liable to limited generality, which leads to a false prediction of optimum. EORKS applies Kriging variance to establish the reliable region neighbouring the learning samples to constrain the evolutionary searches of the surrogate. The verified quasi-optimum is used as an additional sample to dynamically update the regional model according to the prediction accuracy. A hybrid infilling strategy switches between the iterative quasi-optima and the maximum expected improvement from Kriging to prevent early convergence of local optimum. EORKS provides superior optima in several benchmark functions and an engineering design problem, using much smaller samples compared with the literature results, which demonstrates the sampling efficiency and searching robustness.

description: We give a review of the works devoted to the treatment of the Kerr super black hole solution as a spinning particle. The real, complex and stringy structures of the Kerr and super-Kerr geometries are discussed, as well as the recent results on the regular matter source for the Kerr spinning particle. It is shown that the source has to represent a rotating bag-like bubble having (A)dS interior and a smooth domain wall boundary. The given by Morris supersymmetric generalization of the U(I) x U'(I) field model (which was used by Witten to describe cosmic superconducting strings) is considered, and it is shown that this model can be adapted for description of superconducting bags having a long range external electromagnetic field and another gauge field confined inside the bag.

Tie hokara, tie vaka: Black man, white man : a study of the New Georgia Group to 1925

description: This thesis is a study of the behaviour of Melanesians and Europeans in the New Georgia Group, Solomon Islands, from the beginning of European contact to the mid 1920s. For the first century of contact the islanders of the Group were able to exploit the opportunities created by European intrusion within the framework of their own culture, and to dictate largely the terms of their relationship with the white man. The imposition of colonial rule radically altered the situation. The forcible pacification of the islands destroyed the Melanesians' capacity to constrain the conduct of the Europeans in the Group and in consequence the European exploitation of the islands rapidly accelerated, particularly with regard to the alienation of land, which the colonial administration did much to encourage. The first two decades of colonial rule saw the interests and welfare of the islanders neglected as European commercial, missionary and official factions struggled amongst themselves for status and authority. These conflicts, and the mounting land problems, culminated in the Land Commission of the early 1920s. The Commission, although it too was almost submerged in inter-European rivalries, marked the adoption by the administration of a more responsible attitude towards the islanders. Other administrative reforms followed, and by the mid 1920s the turbulence and disorder that had accompanied colonial rule began to subside.

description: Background: Shell evolution can impact the structure of the nuclei and lead to effects such as shape coexistence. The nuclei around $^{68}$Ni represent an excellent study case, however, spectroscopic information of the neutron-rich, $Z<28$ nuclei is limited. Purpose: The goal is to measure $γ$-ray transitions in $^{66}$Fe, $^{66}$Co and $^{66}$Ni populated in the $β^-$ decay of $^{66}$Mn, to determine absolute $β$-feedings and relative $γ$-decay probabilities and to compare the results with Monte Carlo Shell Model calculations in order to study the influence of the relevant single neutron and proton orbitals occupancies around $Z=28$ and $N=40$. Method: The low-energy structures of $^{65,66}$Fe, $^{66}$Co and $^{66}$Ni were studied in the $β^-$ decay of $^{66}$Mn produced at ISOLDE, CERN. The beam was purified by means of laser resonance ionization and mass separation. The $β$ and $γ$ events detected by three plastic scintillators and two MiniBall cluster germanium detectors, respectively, were correlated in time to build the low-energy excitation schemes and to determine the $β$-decay half-lives of the nuclei. Results: The relative small $β$-decay ground state feeding of $^{66}$Fe obtained in this work is at variant to the earlier studies. Spin and parity $1^+$ was assigned to the $^{66}$Co ground state based on the strong ground state feeding in the decay of $^{66}$Fe as well as in the decay of $^{66}$Co. Experimental log(ft) values, $γ$-ray deexcitation patterns and energies of excited states were compared to Monte Carlo Shell Model calculations. Based on this comparison, spin and parity assignments for the selected number of low-lying states in the $^{66}$Mn to $^{66}$Ni chain were proposed. Conclusions: The $β$-decay chain starting $^{66}$Mn towards $^{66}$Ni, crossing $N=40$, evolves from deformed nuclei to sphericity...

A cyclotron injector for a proton synchroton

description: The problem, set at the beginning of 1953, was to construct and bring into operation a cyclotron which would be suitable as an injector for the Canberra proton synchrotron. The main content of this thesis is concerned with work which has been done towards the solution of the problem. At the time a choice of machine for injection was made the requirement that the injection energy should be in the region of 8 Mev ruled out Cockroft-Walton and electrostatic generations. Thus the choice was between a linear accelerator and a cyclotron. As the resources of the laboratory were to be heavily committed in building the proton synchrotron itself it was felt that it would be better to avoid such an undertaking as the construction of a linear accelerator if a cyclotron could meet the situation. Having on hand a magnet which was used for the model experimental homopolar generator, and which was suitable for a 30 inch cyclotron, further supported the selection of this machine.

description: The bright, strongly variable BL Lac object PKS 2155-304 was observed by XMM for two essentially uninterrupted periods of ~11 and 16 hr on 30-31 May 2000. The strongest variations occurred in the highest energy bands. After scaling for this effect, the three softest bands (0.1-1.7 keV) showed strong correlation with no measurable lag to reliable limits of $τ\ls 0.3$ hr. However, the hardest band (~3 keV) was less well-correlated with the other three, especially on short time scales, showing deviations of ~10-20% in ~1 hr although, again, no significant interband lag was detected. This result and examination of previous ASCA and BeppoSAX cross-correlation functions suggest that previous claims of soft lags on time scales of 0.3-4 hr could well be an artifact of periodic interruptions due to Earth-occultation every 1.6 hr. Previous determinations of the magnetic field/bulk Lorentz factor were therefore premature, as these data provide only a lower limit of $B γ^{1/3} \gs 2.5$ G. The hardest band encompasses the spectral region above the high-energy break; its enhanced variability could be indicating that the break energy of the synchrotron spectrum, and therefore of the underlying electron energy distribution, changes independently of the lower energies.

description: This paper evaluates economic impacts arising from the introduction of high-speed rail (HSR) between Madrid and Barcelona. Using difference-in-differences estimation we estimate an average treatment effect for provinces with stops on the HSR line of 2.4% for economic output, 3.3% for numbers of firms, and 1.1% for labour productivity. We complement our DID results with a synthetic control analysis for Lleida and Tarragona, two provinces that we argue were assigned HSR stations largely due to their incidental location. We find that both the number of firms and labour productivity are substantially higher in these provinces than in their synthetic counterparts.

description: In many unconventional superconductors, the pairing of electrons is driven by the repulsive interaction, which leads to the sign reversal of superconducting gaps along the Fermi surfaces (FS) or between them. However, to measure this sign change is not easy and straightforward. It is known that, in superconductors with sign reversal gaps, non-magnetic impurities can break Cooper pairs leading to the quasiparticle density of states in the superconducting state. The standing waves of these quasiparticles will interfere each other leading to the quasiparticle interference (QPI) pattern which carries the phase message reflecting also the superconducting gap structure. Based on the recently proposed defect-bound-state QPI technique, we explore the applicability of this technique to a typical iron based superconductor FeTe$_{0.55}$Se$_{0.45}$ with roughly equivalent gap values on the electron and hole pockets connected by the wave vector q_2=(0,π). It is found that, on the negative energy side, with the energy slightly below the gap value, the phase reference quantity $|g(q,-E)|\cos(θ_{q,+E}-θ_{q,-E}) becomes negative and the amplitude is strongly enhanced with the scattering vector q_2, but that corresponding to the scattering between the electron-electron pockets, namely q_3=(π,π), keeps all positive. This is well consistent with the theoretical expectation of the s^+- pairing gap and thus serves as a direct visualization of the sign reversal gaps. This experimental observation is also supported by the theoretical calculations with the Fermi surface structure and s^+- pairing gap.

description: We investigate the persistence probability in the Voter model for dimensions d\geq 2. This is achieved by mapping the Voter model onto a continuum reaction-diffusion system. Using path integral methods, we compute the persistence probability r(q,t), where q is the number of ``opinions'' in the original Voter model. We find r(q,t)\sim exp[-f_2(q)(ln t)^2] in d=2; r(q,t)\sim exp[-f_d(q)t^{(d-2)/2}] for 24. The results of our analysis are checked by Monte Carlo simulations.
