description: To construct a prototrophic Corynebacterium glutamicum strain that efficiently produces pyruvate from glucose, the effects of inactivating RamA, a global regulator responsible for activating the oxidative tricarboxylic acid (TCA) cycle, on glucose metabolism were investigated. ΔramA showed an increased specific glucose consumption rate, decreased growth, comparable pyruvate production, higher formation of lactate and acetate, and lower accumulation of succinate and 2-oxoglutarate compared to the wild type. A significant decrease in pyruvate dehydrogenase complex activity was observed for ΔramA, indicating reduced carbon flow to the TCA cycle in ΔramA. To create an efficient pyruvate producer, the ramA gene was deleted in a strain lacking the genes involved in all known lactate- and acetate-producing pathways. The resulting mutant produced 161 mM pyruvate from 222 mM glucose, which was significantly higher than that of the parent (89.3 mM; 1.80-fold).

Unsteady Hydrodynamics of Tidal Stream Turbines
Creators: name: McNae, Duncan Murray
Publisher: name: Imperial College London
Year: 2013

description: The unsteady hydrodynamics of tidal stream turbines have been investigated using numerical methods and experiments. Dynamic inflow, which represents the change in backflow induced by the circulation present in the wake due to variations in rotor loading, is the particular focus of this work. An implementation of an unsteady vortex lattice method has been developed for modelling tidal stream turbines in a variety of flow conditions. The vortex lattice method is an inviscid potential flow solver, with the blades represented as surfaces on the camber line. The vortex lattice method is used to analyse the difference between a sudden collective change in blade pitch, compared with a sudden change in mean flow. The observed differences are explained with the examination of several simulation properties, such as the wake induced flow field. The vortex lattice method is also used to model a tidal turbine in an oscillatory flow environment. Additionally, experiments have been conducted in a recirculating water flume. A scale turbine model is mounted on a controllable carriage, which can move arbitrarily along the flow direction. Strain gauges are place at the root of one turbine blade, and on the mounting strut of the turbine. This thesis examines the loading response of the turbine due to oscillation of the carriage and turbine system, over a range of Keulegan-Carpenter numbers and current numbers. The conclusions drawn from the experimental and numerical work describe the degree of importance of dynamic inflow, and will show that it can be responsible for overshoots in turbine thrust loads, and lag in the load response when the turbine is subjected to oscillating flow. Dynamic inflow is shown to have significant influence on the turbine thrust in unsteady flows. Added mass, the inertial force that arises when accelerating a body through a fluid is also investigated with two-dimensional unsteady airfoil theory, and is estimated to have an important role in the unsteady loading of tidal stream turbines. A two-bladed device is the main point of interest in this thesis, however the concepts can be extended for many rotor designs.
Performance of a tracking telescope for crystal channeling measurements and evaluation of the CMS Binary Chip
Creators: name: Ferguson, William
Publisher: name: Imperial College London
Year: 2013

description: The High-Luminosity LHC (HL-LHC) foresees an increase in luminosity towards 5×10^34 cm^-2 s^-1 over the next decade. Increased luminosity will have heavy implications for the CMS Tracker, due to increased detector occupancies, trigger rates and radiation damage. Notable areas for development in the Tracker include sensor and readout systems. Additionally, CMS will for the first time require the use of Tracker information in the Level-1 Trigger. A beam telescope has been designed and constructed for the primary purpose of testing future detector modules for upgrades of the CMS Tracker. The telescope is based on the readout chain of the CMS Tracker, and measures the trajectories of charged particles with the use of five pairs of orthogonal silicon strip sensors. Beam tests have been carried out in the H8 proton beamline at CERN through the UA9 collaboration, which looks into the phenomenon of crystal channeling as a possible means of improved beam collimation. The telescope was found to have good performance and has allowed the observation of crystal channeling in a variety of crystals. The telescope has also been tested in a heavy ion beam at the H8 beamline. Large signals in the telescope sensors have been shown to momentarily saturate the APV25 readout chip, which has led to the need for modified hit reconstruction. The telescope has been shown to perform sufficiently well to allow measurements of crystal channeling of heavy ions. The increased data rates at the HL-LHC and the need for compatibility with existing systems necessitate the use of a binary, unsparsifed chip for the readout of silicon strips in the upgraded CMS Tracker. The CMS Binary Chip is a prototype of such a chip, and has been tested in conjunction with the beam telescope at the H8 proton beam. The chip has been shown to perform well.

Pronounced grain boundary network evolution in nanocrystalline Cu subjected to large cyclic strains

description: The grain boundary network of nanocrystalline Cu foils was modified by the systematic application of cyclic loadings and elevated temperatures having a range of magnitudes. Most broadly, the changes to the boundary network were directly correlated to the applied temperature and accumulated strain, including a 300% increase in the twin length fraction. By independently varying each treatment variable, a matrix of grain boundary statistics was built to check the plausibility of hypothesized mechanisms against their expected temperature and stress/strain dependences. These comparisons allow the field of candidate mechanisms to be significantly narrowed. Most importantly, the effect of temperature and strain on twin length fraction were found to be strongly synergistic, with the combined effect being ~150% that of the summed individual contributions. Looking beyond scalar metrics, an analysis of the grain boundary network showed that twin related domain formation favored larger sizes and repeated twin variant selection over the creation of many small domains with diverse variants. Taken together, the evidence indicates that shear-coupled boundary migration twinning is the most likely explanation for grain boundary engineering in nanocrystalline Cu.

description: We generalize the mechanism proposed in [hep-th/0005016] and show that a four-dimensional relativistic tensor theory of gravitation can be obtained on a delta-function brane in flat infinite-volume extra space. In particular, we demonstrate that the induced Ricci scalar gives rise to Einstein's gravity on a delta-function type brane if the number of space-time dimensions is bigger than five. The bulk space exhibits the phenomenon of infrared transparency. That is to say, the bulk can be probed by gravitons with vanishing four-dimensional momentum square, while it is unaccessible to higher modes. This provides an attractive framework for solving the cosmological constant problem.

Affective Adaptation of Social Norms in Workplace Design
Creators: name: Santos, Monica
Publisher: name: Imperial College London
Year: 2013

description: Open-plan offices are common in today's organisations. These types of workplaces require people to share a common space, where violation of (implicitly or explicitly stated) social norms can cause instances of incivility. If nothing is done to avoid these situations, bad feeling can lead to diminished productivity and cooperation, and, in the long-term, to more serious problems, such as conflict and aggression. A critical review of literature shows the effects of workplace incivility and the need for an internal reparation mechanism. Inspired by convergence of pervasive, adaptive and affective computing, we have designed and developed a self-regulatory platform for successful collective action, based on participatory adaptation and fair information practises, which we called MACS. MACS addresses the problem of incivility and aims at improving the Quality of Experience in shared workplaces. This thesis presents all studies that led to the development of MACS. Through the analysis of an online questionnaire we gathered information about incivility in shared workplaces, how people deal with those situations, and awareness about uncivil self-behaviours. We concluded the main issue while sharing a workplace is noise, and most people will try to change their own behaviour, rather than confronting the person being uncivil. MACS's avatar-based interface was developed with the purpose of heightening self-awareness and cueing the appropriate social norms, while providing a good User Experience (UX). Avatars created to people's image, rather than photos, were used, to keep MACS's tone light and relatively unintrusive, while still creating self-awareness. MACS's final version went through UX testing, where 6 people were filmed while performing tasks in MACS. The intended work-flow and user interfaces to support the smooth passage of the work-flow have been validated by the UX user testing. There is some preliminary evidence suggesting apology will elicit empathic responses in MACS. Finally, this thesis proposes guidelines for workplace design, which are founded on participatory creation and change of social norms, and ways to make sure they are enforced. In this sense, MACS can also be seen as a prototypical example of a socio-technical system being used as platform for successful collective action.

description: By combining Monte Carlo simulations and analytical models, we demonstrate and explain how the gas-to-liquid phase transition of colloidal systems confined to a spherical surface depends on the curvature and size of the surface, and on the choice of thermodynamic ensemble. We find that the geometry of the surface affects the shape of the free energy profile and the size of the critical nucleus by altering the perimeter-area ratio of isotropic clusters. Confinement to a smaller spherical surface results in both a lower nucleation barrier and a smaller critical nucleus size. Furthermore, the liquid domain does not grow indefinitely on a sphere. Saturation of the liquid density in the grand canonical ensemble and the depletion of the gas phase in the canonical ensemble lead to a minimum in the free energy profile, with a sharp increase in free energy for additional growth beyond this minimum.

Dependence of Lattice Hadron Masses on External Magnetic Fields

description: We study the variation of the hadron masses in the presence of external magnetic fields of strength of the order of the masses themselves. We identify the main factors affecting the lattice simulation results: - the boundary discontinuities for $eB << 2π/ L^2 a^2$. - the SU(6) choice of the hadron wave-function. We confirm qualitatively the earlier theoretical ansatz on the linear behaviour of the masses with the magnetic field and, as a by-product, we improve the lattice measurements of the nucleon magnetic moments. However our systematic and statistical errors preclude us from measuring the theoretically predicted field strength at which the proton becomes heavier than the neutron.

description: One of the main purposes of long-baseline neutrino experiments is to unambiguously measure the CP violating phase in the neutrino sector within the three neutrino oscillation picture. In the presence of physics beyond the Standard Model, the determination of the CP phase will be more difficult, due to the already known degeneracy problem. Working in the framework of non-standard interactions (NSI), we compute the appearance probabilities in an exact analytical formulation and analyze the region of parameters where the confusion problem is present. We also discuss some cases where the falsification of the NSI parameters can be done in long-baseline experiments.

description: The pulsar PSR B1259-63 is in a highly eccentric 3.4-yr orbit with the Be star SS 2883. Timing observations of this pulsar, made over a 7-yr period using the Parkes 64-m radio telescope, cover two periastron passages, in 1990 August and 1994 January. The timing data cannot be fitted by the normal pulsar and Keplerian binary parameters. A timing solution including a (non-precessing) Keplerian orbit and timing noise (represented as a polynomial of fifth order in time) provide a satisfactory fit to the data. However, because the Be star probably has a significant quadrupole moment, we prefer to interpret the data by a combination of timing noise, dominated by a cubic phase term, and $\dotω$ and $\dot x$ terms. We show that the $\dotω$ and $\dot x$ are likely to be a result of a precessing orbit caused by the quadrupole moment of the tilted companion star. We further rule out a number of possible physical effects which could contribute to the timing data of PSR B1259-63 on a measurable level.

description: The time-convolutionless (TCL) quantum master equation provides a powerful tool to simulate reduced dynamics of a quantum system coupled to a bath. The key quantity in the TCL master equation is the so-called kernel or generator, which describes effects of the bath degrees of freedom. Since the exact TCL generators are usually hard to calculate analytically, most applications of the TCL generalized master equation have relied on approximate generators using second and fourth order perturbative expansions. By using the hierarchical equation of motion (HEOM) and extended HEOM methods, we present a new approach to calculate the exact TCL generator and its high order perturbative expansions. The new approach is applied to the spin-boson model with different sets of parameters, to investigate the convergence of the high order expansions of the TCL generator. We also discuss circumstances where the exact TCL generator becomes singular for the spin-boson model, and a model of excitation energy transfer in the Fenna-Matthews-Olson complex.

description: We present a calculating method for the quark and lepton mixing angles. After a general discussion in field theoretic models, we present a working model from a string compactification through $Z_{12-I}$ orbifold compactification. It is beyond presenting just three families of the standard model but is the first example from string compactification successfully fitting to the observed data. Assuming that all Yukawa couplings from string compactification are real, we also comment on a relation between the CP phases in the Jarlskog determinants obtained from the CKM and PMNS matrices. The flipped SU(5) model leads to the doublet-triplet splitting and possible proton decay operators. It is shown that the vacuum expectation values can be tuned such that the proton lifetime is long enough.

On a Hamiltonian regularization of scalar conservation laws

Year: 2024
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: In this paper, we propose a Hamiltonian regularization of scalar conservation laws, which is parametrized by $\ell > 0$ and conserves an $H^1$ energy. We prove the existence of global weak solutions for this regularization. Furthermore, we demonstrate that as $\ell$ approaches zero, the unique entropy solution of the original scalar conservation law is recovered, providing justification for the regularization. This regularization belongs to a family of non-diffusive, non-dispersive regularizations that were initially developed for the shallow-water system and extended later to the Euler system. This paper represents a validation of this family of regularizations in the scalar case.

description: We present optical spectroscopic and photometric observations of the nearby type Ic supernova (SN Ic) SN 2014L. This SN was discovered by the Tsinghua-NAOC Transient Survey (TNTS) in the nearby type-Sc spiral galaxy M99 (NGC 4254). Fitting to the early-time light curve indicates that SN 2014L was detected at only a few hours after the shock breakout, and it reached a peak brightness of $M_{\rm V} = -17.73 \pm 0.28$ mag ($L= [2.06\pm 0.50] \times 10^{42}$ erg s$^{-1}$) approximately 13 days later. SN 2014L shows a close resemblance to SN 2007gr in the photometric evolution, while it shows stronger absorption features of intermediate-mass elements (especially \CaII) in the early-time spectra. Based on simple modeling of the observed light curves, we derived the mass of synthesized $^{56}$Ni as $M_{\rm Ni} = 0.075 \pm 0.025 M_{\odot}$, and the mass and total energy of the ejecta as $M_{\rm ej} = 1.00 \pm 0.20 M_\odot$ and $E_{\rm ej}=1.45\pm0.25$ foe, respectively. Given these typical explosion parameters, the early detection, and the extensive observations, we suggest that SN 2014L could be a template sample for the investigation of SNe Ic.

description: We report a high statistics simulation of Ising spins coupled to 2D quantum gravity in the Regge calculus approach using triangulated tori with up to $512^2$ vertices. For the constant area ensemble and the $dl/l$ functional measure we definitively can exclude the critical exponents of the Ising phase transition as predicted for dynamically triangulated surfaces. We rather find clear evidence that the critical exponents agree with the Onsager values for static regular lattices, independent of the coupling strength of an $R^2$ interaction term. For exploratory simulations using the lattice version of the Misner measure the situation is less clear.

description: Principal component analysis (PCA) is known to be sensitive to outliers, so that various robust PCA variants were proposed in the literature. A recent model, called REAPER, aims to find the principal components by solving a convex optimization problem. Usually the number of principal components must be determined in advance and the minimization is performed over symmetric positive semi-definite matrices having the size of the data, although the number of principal components is substantially smaller. This prohibits its use if the dimension of the data is large which is often the case in image processing. In this paper, we propose a regularized version of REAPER which enforces the sparsity of the number of principal components by penalizing the nuclear norm of the corresponding orthogonal projector. If only an upper bound on the number of principal components is available, our approach can be combined with the L-curve method to reconstruct the appropriate subspace. Our second contribution is a matrix-free algorithm to find a minimizer of the regularized REAPER which is also suited for high-dimensional data. The algorithm couples a primal-dual minimization approach with a thick-restarted Lanczos process. This appears to be the first efficient convex variational method for robust PCA that can handle high-dimensional data. As a side result, we discuss the topic of the bias in robust PCA. Numerical examples demonstrate the performance of our algorithm.

description: The Atiyah-Patodi-Singer (APS) index theorem relates the index of a Dirac operator to an integral of the Pontryagin density in the bulk (which is equal to global chiral anomaly) and an $η$ invariant on the boundary (which defines the parity anomaly). We show that the APS index theorem holds for configurations with domain walls that are defined as surfaces where background gauge fields have discontinuities.

description: In this two session interview, Robert Cummings discusses his activities with the Massachusetts Society for the Prevention of Cruelty to Animals (MSPCA), with a particular focus on the legal aspects of animal protection. He begins by describing his initial involvement with the MSPCA as a first major account after starting in law in 1957. He describes MSPCA efforts to keep shelter dogs from being used in research at Harvard, legal work regarding animals, and the nature of professionalism. He analyzes the MSPCA's moderate and results-oriented approach in contrast to approach of activist Brian Davies, and discusses collaborations and differences with the New England Anti-Vivisection Society (NEAVS). He addresses fundraising and the characteristics of donors. He speaks about mistreatment of farm animals including abused horses, issues in livestock transport, and the treatment of animals for halal/kosher markets. In the second session, Cummings begins by discussing connections between violence against animals and humans in legal context. He also discusses the MSPCA's activities and future plans at the time of the interview.
Modified Friedmann Equations from Tsallis Entropy

description: It was shown by Tsallis and Cirto that thermodynamical entropy of a gravitational system such as black hole must be generalized to the non-additive entropy, which is given by $S_h=γA^β$, where $A$ is the horizon area and $β$ is the nonextensive parameter \cite{Tsa}. In this paper, by taking the entropy associated with the apparent horizon of the Friedmann-Robertson-Walker (FRW) Universe in the form of Tsallis entropy, and assuming the first law of thermodynamics, $dE=T_hdS_h+WdV$, holds on the apparent horizon, we are able to derive the corresponding Friedmann equations describing the dynamics of the universe with any spatial curvature. We also examine the time evolution of the total entropy and show that the generalized second law of thermodynamics is fulfilled in a region enclosed by the apparent horizon. Then, modifying the emergence proposal of gravity proposed by Padmanabhan and calculating the difference between the surface degrees of freedom and the bulk degrees of freedom in a region of space, we again arrive at the modified Friedmann equation of the FRW Universe with any spatial curvature which is the same as one obtained from the first law of thermodynamics. We also study the cosmological consequences of Tsallis cosmology. Interestingly enough, we find that this model can explain simultaneously the late time acceleration in the universe filled with pressureless matter without invoking dark energy, as well as the early deceleration. Besides, the age problem can be circumvented automatically for an accelerated universe and is estimated larger than $3/2$ age of the universe in standard cosmology. For $β=2/5$, we find $13.12$ Gyr $< t_0 < 16.32 $ Gyr, which is consistent with recent observations. We also comment on the density perturbation in the context of Tsallis cosmology.

On Jet Features in the Optical Spectra of Cataclysmic Variables

description: Blue- and red-shifted Hydrogen and Helium satellite recombination lines have recently been discovered in the optical spectra of at least two supersoft X-ray sources (SSSs), RX J0513-069 and RX J0019.8+2156, and tentatively also in one short-period cataclysmic variable star (CV), the recurrent nova T Pyx. These features are thought to provide evidence for the presence of highly collimated jets in these systems. No similar spectral signatures have been detected in the spectra of other short-period CVs. Here, we ask if this apparent absence of ``jet lines'' in the spectra of most CVs already implies the absence of jets of the kind that appear to be present in the SSSs and perhaps T Pyx, or whether the current lack of jet detections in CVs can still be ascribed to observational difficulties. To answer this question, we derive a simple, approximate scaling relation between the expected equivalent widths (EWs) of the jet lines in both types of systems and the accretion rate through the disk. We then use this relation to predict the strength of jet lines in the spectra of ``ordinary'' CVs, i.e. systems characterized by somewhat lower accretion rates than T Pyx. Making the assumption that the features seen in T Pyx are indeed jet lines and using this system as a reference point, we find that if jets are present in many CVs, they may be expected to produce satellite recombination lines with EWs of a few hundredths to a few tenths of Angstroms in suitably selected systems. A similar prediction is obtained if the SSS RX J0513-069 is used as a reference point. Such EWs are small enough to account for the non-detection of jet features in CVs to date, but large enough to allow them to be detected in data of sufficiently high quality, if they exist.

Degeneration of Kummer surfaces

description: We prove that a Kummer surface defined over a complete strictly Henselian discretely valued field $K$ of residue characteristic different from 2 admits a strict Kulikov model after finite base change. The Kulikov models we construct will be schemes, so our results imply that the semistable reduction conjecture is true for Kummer surfaces in this setup, even in the category of schemes. Our construction of Kulikov models is closely related to an earlier construction of Künnemann, which produces semistable models of Abelian varieties. It is well-known that the special fibre of a strict Kulikov model belongs to one of three types, and we shall prove that the type of the special fibre of a strict Kulikov model of a Kummer surface and the toric rank of a corresponding Abelian surface are determined by each other. We also study the relationship between this invariant and the Galois representation on the second $\ell$-adic cohomology of the Kummer surface. Finally, we apply our results, together with earlier work of Halle-Nicaise, to give a proof of the monodromy conjecture for Kummer surfaces in equal characteristic zero.

Tumour necrosis factor-α (TNF) receptor subtype signalling in acute lung injury - a therapeutic approach
Creators: name: Bertok, Szabolcs
Publisher: name: Imperial College London
Year: 2013

description: To date no definite treatment exists for acute lung injury (ALI), only supportive therapy, among which mechanical ventilation is an important tool; however ventilation itself may exacerbate the underlying injury, termed ventilator-induced lung injury (VILI). The pro-inflammatory cytokine tumour necrosis factor alpha (TNF) has been consistently implicated in the pathogenesis of ALI/VILI, however clinical trials with anti-TNF therapy failed to improve the outcome. TNF acts on two cell-surface receptors (TNFRs), p55 and p75, and knock-out studies in ALI/VILI indicate they have directly opposing roles, i.e. promoting or protecting against pulmonary oedema, respectively, but it remains unclear where these signalling mechanisms take place, being the endothelial or epithelial side of the alveolar-capillary membrane. This project had two main aims: to characterise the expression profile and roles of TNF receptor subtypes on each side of the alveolarcapillary membrane and to modulate ALI progression in mouse models by targeting individual TNFRs accordingly. Characterisation studies on freshly harvested mouse pulmonary endothelial cells (PECs) using flow cytometry indicated expression of both receptors with dominance of p55. Knock-out and pharmacological inhibition studies in vivo and in vitro, respectively, found p55 to be the major mediator of TNF-induced adhesion molecule expression on PECs, with a similar but less potent role for p75 that varied across adhesion molecules. Endotoxaemia resulted in rapid shedding of p55 on PECs while expression of p75 was preserved, indicating that the relative role of the receptors may change during inflammatory conditions. Specific inhibition of intraalveolar p55 signalling by domain antibodies significantly attenuated both pulmonary oedema and inflammation in mouse models of VILI and acid-aspiration. These data offer new, potentially clinically applicable insights into the involvement of TNFR biology in ALI and the novel domain antibody technology may open a new therapeutic approach for patients who suffer from, or at risk of ALI.

description: We study pure 2D Euclidean quantum gravity with $R^2$ interaction on spherical lattices, employing Regge's formulation. We attempt to measure the string susceptibility exponent $γ_{\rm str}$ by using a finite-size scaling Ansatz in the expectation value of $R^2$. To check on effects of the path integral measure we investigate two scale invariant measures, the "computer" measure $dl/l$ and the Misner measure $dl/\sqrt A$.
