description: RXTE has been operating for nearly 2 years and is planning the third. The spacecraft performance has been good and the three instruments are operating well. Observations have been made of the range of targets suitable for RXTE, including such different objects as accreting neutron stars and black holes, stellar flares, and supernova remnants. The goals of studying high time resolution and broad energy range and optimizing multi-wavelength participation are yielding important results. Oscillations found from low-mass X-ray binaries probably are signatures of the spin of the neutron stars and of the shortest orbital periods around the neutron stars. These are constraining neutron star parameters. Oscillation and spectral results from black hole candidates bring into the realm of possibility the possibilities of measuring the spins of the black holes and using X-ray data to test predictions of gravitation theory. Multi-wavelength observations are leading to identification of the locations of the X-ray emission regions and, in the case of the micro-quasars, to understanding of the mechanisms for jet formation. Recently faster observing response than originally planned has made possible some RXTE contributions to identification of gamma-ray bursts.

description: We convert the second class Proca model into a first class theory by using the generalised prescription of Batalin, Fradkin and Tyutin. We then show how a basic set of gauge invariant fields in the embedded model can be identified with the fundamental fields in the proca model as well as with the observables in the Stückelberg model or in the model involving the interaction of an abelian 2-form field with the Maxwell field. The connection of these models with the massive Kalb-Ramond model is also elucidated within a path integral approach.

description: In his pioneering work on singular shells in general relativity, Lanczos had derived jump conditions across energy-momentum carrying hypersurfaces from the Einstein equation with codimension 1 sources. However, on the level of the action, the discontinuity of the connection arising from a codimension 1 energy-momentum source requires to take into account two adjacent space-time regions separated by the hypersurface. The purpose of the present note is to draw attention to the fact that Lanczos' jump conditions can be derived from an Einstein action but not from an Einstein-Hilbert action.

The regulatory role of TRAF3 in myeloid cell-mediated control of chronic inflammation and tumor immunity
Creators: name: Zhu, Sining
Publisher: name: No Publisher Supplied
Year: 2021

description: Tumor necrosis factor receptor-associated factor 3 (TRAF3) is a cytoplasmic adaptor protein and a signal transducer of a variety of immune receptors involved in both adaptive and innate immunity. Previous study on myeloid cell-specific Traf3-deficient (M-Traf3-/-) mice revealed that aging M-Traf3-/- mice spontaneously develop chronic inflammation and tumors accompanied by striking expansion of myeloid-derived suppressor cells (MDSCs), a heterogeneous population of immature myeloid cells with remarkable ability to suppress both innate and adaptive immune responses. To further investigate the role of myeloid cell TRAF3 in regulating MDSC expansion, we utilized an inflammation model by repeated injections of heat-killed Bacillus Calmette-Guérin (BCG), which closely resembles chronic inflammation and induces MDSC hyperexpansion in the spleen of young M-Traf3-/- mice. Using a new tumor transplantation model, we showed that in the presence of heat-killed BCG-induced chronic inflammation, young adult M-Traf3-/- mice with MDSC hyperexpansion failed to control B lymphoma growth and metastasis, which was associated with altered phenotypes of CD8, CD4 T cells and NK cells. Our results from mixed bone marrow (BM) chimera experiments demonstrated that TRAF3 inhibited MDSC expansion via both cell-intrinsic and cell-extrinsic mechanisms. Cytokine array analysis and in vivo neutralization experiments identified G-CSF as the major extrinsic driver of MDSC expansion in M-Traf3-/- mice. Our detailed mechanistic investigation revealed that elevated levels of G-CSF in M-Traf3-/- mice were mainly contributed by a novel CCL22- CCR4-G-CSF axis acting in Traf3-/- inflammatory monocytes and macrophages. Furthermore, we investigated the cell-intrinsic mechanism underlying TRAF3-mediated regulation of MDSC expansion and elucidated a novel GM-CSF-TRAF3-STAT3 signaling axis that controls the proliferation of MDSCs. Overall, our findings uncover novel mechanistic insights on how myeloid cell TRAF3 restrains MDSC expansion, thereby preventing overzealous inflammation and indirectly promoting tumor immunity. Findings from this study will bring a new perspective for the design of novel MDSC-targeted therapeutic approaches for the treatment of chronic inflammation and cancers.

description: High precision astrometry now enables to measure the time drift of astrophysical observables in real time, hence providing new ways to probe different cosmological models. This article presents a general derivation of the redshift and direction drifts for general observers. It is then applied to the standard cosmological framework of a Friedmann-Lemaitre space- time including all effects at first order in the cosmological perturbations, as well as in the class of spatially anisotropic universe models of the Bianchi I family. It shows that for a general observer, the direction drift splits into a parallax and an aberration drifts and order of magnitude estimates of these two components are provided. The multipolar decomposition of the redshift and aberration drifts is also derived and shows that the observer's peculiar velocity contributes only as a dipole whereas the anisotropic shear contributes as a quadrupole.

Experimental study of pulsed power driven radiative shockwaves in noble gases
Creators: name: Skidmore, Jonathan William
Publisher: name: Imperial College London
Year: 2013

description: The use of plastic disks coated with a thin film ( ~1 µm) of Aluminium has been investigated as a control mechanism for the shockwave formed from a radial foil z-pinch in the presence of an ambient medium. Experiments were carried out on the MAGPIE (1:4MA, 250ns rise time) facility at Imperial College London. It has been found that plastic formers replicate the results seen in standard radial foil z-pinch configurations and dramatically increase the working pressure of the experimental setup. The configuration produces a strong radiative shockwave driven with constant velocity ( ≥ 25km/s) for long time ( ≥ 400ns) and spatial scales (cm). Through comparison with standard radial foil configuration results a new formation model for shockwaves from radial foil z-pinches is proposed. The model is found to be in good agreement with all experimental velocity and profile data. The model indicates a means to maximise the shockwave velocity and alter the profile. Investigation of the effect of ambient medium atomic mass on shockwave parameters was then undertaken using the plastic former configuration. Experimental results demonstrate scaling of shock compression opposite to that found in 1D radiation hydro-dynamic simulations. Evidence of a thermal instability in the post-shock cooling region is linked to a decrease in compression for higher atomic masses due to increased radiative cooling. Increases in post-shock temperature and ionization have been measured with decreased radial distance from a strongly cooling hydrodynamic jet. Regions of observed thermal instability for Xenon and Krypton agree with those expected from evaluation of theoretical cooling functions. The possibility of temporal oscillation of the shock velocity due to thermal instability is also investigated.

Solar Electricity from Concentrator Photovoltaic Systems
Creators: name: Chan, Ngai Lam Alvin
Publisher: name: Imperial College London
Year: 2013

description: This thesis examines the prediction of concentrator photovoltaic system performance, and a model is presented where estimates are made using basic, fundamental material and atmospheric parameters, and successfully validated against measurements from a deployed system, to within 2% accuracy. A method to characterise the impact of individual atmospheric parameters on concentrator photovoltaic system performance is detailed and results are presented for potential deployment locations around the globe, demonstrating substantial differences in energy yield prediction accuracy if insufficient information is available, with up to 75% relative difference in energy yield and levelised cost of energy between basic and detailed simulations. In addition, the competitiveness of concentrator photovoltaic systems in different locations are benchmarked against existing technologies, showing significant geographical variation in their financial viability. The material quality in single and multijunction solar cells and its effect on the selection of optimal solar cell designs is investigated and the radiative efficiency of a device is proposed as a figure of merit to evaluate material quality. The optimal band gaps are shown to vary substantially depending on material quality at low solar concentrations, by hundred of milli-electron-volts, with ramifications for future solar cell designs. The impact of photon management, through radiative coupling, on cell performance is quantified for current and future high efficiency multijunction solar cell structures. Up to 5% enhancement due to radiative coupling can be expected for quad-junction solar cells, but current designs can expect below 1% enhancement. The work covered in this thesis has investigated and highlighted the potential problems associated with not fully understanding the atmospheric conditions in which concentrator photovoltaic systems operate, providing evidence and impetus for additional ground measurements or a drastic improvement in satellite-based measurement of atmospheric conditions. By integrating atmospheric parameters into an existing concentrator photovoltaic system modelling tool, new methods to characterise these conditions has been developed rigorously and accurately simulate system behaviour, a valuable resource to the field. In the design of optimal band gaps for multijunction solar cells, the work in this thesis shows that the material quality must be carefully considered in any design. A novel method has been developed to quantify material quality and provide a benchmark of state-of-the-art achieved values. The role of photon management in the form of radiative coupling is quantified, through the first examination of enhancement due to the effect, under realistic atmospheric conditions. This gives cell designers realistic expectations for performance enhancement.

description: We consider an eleven dimensional supergravity compactified on $K3\times T^2$ and show that the resulting five dimensional theory has identical massless states as that of heterotic string compactified on a specific five torus $T^5$. The strong-weak coupling duality of the five dimensional theory is argued to represent a ten dimensional Type $IIA$ string compactified on $K3 \times S^1$, supporting the conjecture of string-string duality in six dimensions. In this perspective, we present magnetically charged solution of the low energy heterotic string effective action in five dimensions with a charge defined on a three sphere $S^3$ due to the two form potential. We use the Poincare duality to replace the antisymmetric two form with a gauge field in the effective action and obtain a string solution with charge on a two sphere $S^2$ instead of that on a three sphere $S^3$ in the five dimensional spacetime. We note that the string-particle duality is accompanied by a change of topology from $S^3$ to $S^2$ and viceversa.

From outcrop analogue to flow simulation: modelling heterogeneity in shallow-marine reservoirs
Creators: name: Graham, Gavin Henry
Publisher: name: Imperial College London
Year: 2013

description: Shallow-marine reservoirs are typically complex, containing hierarchically arranged heterogeneity in inter-well volumes, at scales that are challenging to represent in reservoir models. Permeability contrasts associated with clinoforms are one such heterogeneity, but at present there are no modelling tools available to automate the generation of multiple three-dimensional (3D) clinoform surfaces. Consequently, clinoforms are rarely incorporated in models of shallow-marine reservoirs, even when their potential impact on flow is recognized. A numerical algorithm that generates multiple 3D clinoforms is presented. The algorithm is validated via construction of 3D, surface-based reservoir models of: (1) fluvial-dominated delta-lobe deposits exposed at outcrop (Cretaceous Ferron Sandstone Member, Utah, USA); and (2) a deltaic reservoir using a sparse subsurface dataset (Jurassic Sognefjord Formation, Troll Field, Norwegian North Sea). We use a suite of 3D reservoir models constructed with the clinoform-modelling algorithm and outcrop-analogue data (Cretaceous Ferron Sandstone Member, Utah) to quantify the impact of clinoforms on fluid flow in the context of: (1) other uncertainties in reservoir characterisation, such as the impact of bed-scale heterogeneity on vertical permeability; and (2) reservoir engineering decisions, including oil production rate. Clinoforms are difficult to identify using production data, but our results indicate that they can significantly influence hydrocarbon recovery and their impact can be larger than that of other geological heterogeneities and of reservoir engineering decisions. Vertical permeability within distal delta-front facies comprising interbedded sandstones and shales is found to be an important influence on sweep within clinothems. However, it is difficult to characterize these intervals from subsurface datasets. A digital outcrop modelling method is presented and applied to capture the geometry and architecture of sandbodies in such deposits in an outcrop analogue (G2 parasequence, Grassy Member, Blackhawk Formation, Utah, USA). We use the resulting digital outcrop model to make a preliminary interpretation of 3D gutter cast geometry.

description: Since its inception, many physicists have seen in quantum mechanics the possibility, if not the necessity, of bringing cognitive aspects into the play, which were instead absent, or unnoticed, in the previous classical theories. In this article, we outline the path that led us to support the hypothesis that our physical reality is fundamentally conceptual-like and cognitivistic-like. However, contrary to the 'abstract ego hypothesis' introduced by John von Neumann and further explored, in more recent times, by Henry Stapp, our approach does not rely on the measurement problem as expressing a possible 'gap in physical causation', which would point to a reality lying beyond the mind-matter distinction. On the contrary, in our approach the measurement problem is considered to be essentially solved, at least for what concerns the origin of quantum probabilities, which we have reasons to believe they would be epistemic. Our conclusion that conceptuality and cognition would be an integral part of all physical processes comes instead from the observation of the striking similarities between the non-spatial behavior of the quantum micro-physical entities and that of the human concepts. This gave birth to a new interpretation of quantum mechanics, called the 'conceptualistic interpretation', currently under investigation within our group in Brussels.

description: We investigate the role of quantum fluctuations in the system composed of two branes bounding a region of AdS. It is shown that the modulus effective potential generated by quantum fluctuations of both brane and bulk fields is incapable of stabilizing the space naturally at the separation needed to generate the hierarchy. Consequently, a classical stabilization mechanism is required. We describe the proper method of regulating the loop integrals and show that, for large brane separation, the quantum effects are power suppressed and therefore have negligible affects on the bulk dynamics once a classical stabilization mechanism is in place.

A critical assessment of turbulent flow over textured superhydrophobic surfaces
Creators: name: Jelly, Thomas
Publisher: name: Imperial College London
Year: 2013

description: Over the past century, a sustained effort has been expended on the research and development of surfaces that reduce the amount of drag experienced by a fluid as it passes by, motivated by both environmental and economic savings. Superhydrophobic surfaces have recently emerged as an attractive means to reduce the levels of skin-friction drag under both laminar and turbulent flow conditions. A superhydrophobic state is attained naturally or synthetically through a combination of surface topology and surface chemistry and can, in some cases, support a free-stress gas-liquid interface. In the presence of bulk fluid motion, the interfaces permit a finite slip velocity which has been credited to the reduction of the average wall shear stress. The fundamental drag reduction mechanism, however, remains unclear. In order to accurately resolve the full spectrum of turbulent scales, direct numerical simulations of fully turbulent channel flow over superhydrophobic textures at a friction Reynolds number of Reτ ≈ 180 were conducted. The instantaneous flow fields were subject to triple decomposition which permits statistical quantities to be accumulated in a phase-averaged form. From these phase-averaged statistics the mean, periodic and stochastic fluid motions can be considered independently. Following a detailed statistical analysis, the contributions of the mean, periodic and stochastic fluid motions towards the local levels of wall shear stress were determined by the derivation and evaluation of an appropriate skin-friction identity. In addition, a new modification to superhydrophobic surfaces is investigated by means of meandering the surface topology in the streamwise direction. Relative to a streamwise-aligned topology, it was anticipated that superior drag reduction would be achieved due to the addition of an oscillatory spanwise motion to the mean flow.

Degrees of freedom in two dimensional string theory

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

description: We discuss two issues regarding the question of degrees of freedom in two dimensional string theory. The first issue relates to the classical limit of quantum string theory. In the classical theory one requires an infinite number of fields in addition to the collective field to describe ``folds'' on the fermi surface. We argue that in the quantum theory these are not additional degrees of freedom. Rather they represent quantum dispersions of the collective field which are {\em not} suppressed when $\hbar \rightarrow 0$ whenever a fold is present, thus leading to a nontrivial classical limit. The second issue relates to the ultraviolet properties of the geometric entropy. We argue that the geometric entropy is finite in the ultraviolet due to {\em nonperturbative} effects. This indicates that the true degrees of freedom of the two dimensional string at high energies is much smaller than what one naively expects.

Control rights in private credit agreements
Creators: name: Daher, Mai
Publisher: name: Imperial College London

description: I examine the effect of creditor control rights on borrowers’ financing policy both ex-ante and ex-post. The novelty introduced by this thesis is the use of an investor protection variable reflecting the pledgeability of a firm’s assets, both at industry and country level, alongside the contractual allocation of control rights, in understanding financial contracting and capital structure mechanics. At industry level, the empirical analysis is first motivated with a model that allows debt contracts to allocate control rights over the reorganization or liquidation decision of distressed firms and where cash flow pledgeability can vary. The model delivers two main predictions: (1) Ex-post, creditor control should be associated with an increased likelihood of resolving financial distress out of court relative to filing for bankruptcy, particularly in industries where assets are easier to collateralize; (2) Ex-ante, creditor control should be associated with an increased use of leverage, particularly in industries where assets are easier to collateralize. Empirical results provide evidence consistent with these two predictions. At country level, strong judicial effectiveness is found to alleviate the effect of the contractual enforcement of rights by creditors on financing policy. Net debt issuing activity declines sharply following a covenant violation, when creditors use their contractual acceleration and termination rights to increase interest rates or halt any further supply of credit. The decline is however found to be less pronounced in countries with stronger legal enforcement. This result is also observable for a variety of financial and investment policy measures including capital expenditures, asset growth and cash holdings, therefore highlighting the importance of strong contract enforcement in reducing financial and investment conservatism following a covenant violation and improving firm performance.

Dynamics on the Edge: Star-Disk Interaction

Subjects: subject: Astrophysics (astro-ph)

description: Our understanding of the dynamical processes which control the structure and evolution of the interaction region between an accretion disk and the central star is reviewed. If the central star is unmagnetized, this interaction is in the form of a classical boundary layer. However, if the central star is strongly magnetized, it is expected that the inner disk is truncated by the stellar field, and the accretion flow follows the stellar field lines to the magnetic poles. Several outstanding questions remain regarding this picture. It is likely that numerical MHD simulations will prove essential to answering these questions. However, in order to model the MHD turbulence, angular momentum transport, and possible dynamo action associated with the dynamics of star-disk interaction, fully three-dimensional simulations spanning long dynamical times are required.

Thin Film Detector for Internal MRI
Creators: name: Segkhoonthod, Khoonsake
Publisher: name: Imperial College London
Year: 2013

description: Thin film detectors that combine a flexible microcoil with a flexible transmission line are presented, for in vivo magnetic resonance imaging of the human bile duct. The thin-film format allows integration on a catheter, which may then be delivered into the duct with the help of a guidewire using a non-magnetic side opening endoscope. The high filling factor obtained using this approach provides very high Signal-to-Noise Ratio (SNR) and image quality, but the overall procedure is much less invasive than surgical intrabiliary MRI. In this thesis, two models are proposed. The first has a multi-turn spiral with integrated tuning and matching capacitors as a detector coil, and a photonic bandgap structure with a periodically patterned ground plane as a transmission line. Commercial electromagnetic modelling software (AWR Microwave Office) is used to perform a detailed analysis of a complete detector system. Coil and cable are both modelled using Axiem, a method of moments solver. Analysis of the reflection and transmission coefficient is used to extract parameters such as characteristic impedance and propagation loss. Parameters are chosen for operation at 63.8 MHz (1H MRI at 1.5T) with a 50 Ω system impedance. Because the first design was implemented without considering MR-safety, a second-generation system was developed. This design uses a figure-of-eight shaped coil used as a detector and also as the resonant element in a magneto-inductive transmission line. As a result, coupling to both the B1 and E fields of the transmitter is prevented. AWR Microwave Office is, again, used to perform a detailed design. Additional electrical parameters such as coupling coefficient, and mutual inductance of the cable are measured and extracted. Mismatch impedance is solved using transformer matching. Analytic models of both designs are also developed and compared with simulation data and to experimental data from prototypes fabricated using copper-clad Kapton.

description: A class of exact solutions to the Born-Infeld field equations, over manifolds of any even dimension, is constructed. They are an extension of the self-dual configurations. They are local minima of the action for riemannian base manifolds and local minima of the Hamiltonian for pseudo-riemannian ones. A general explicit expression for the Born-Infeld determinant is obtained, for any dimension of space-time.

Terahertz generation in dual-color laser: continuum electron in strong-field single-atom ionization

description: The terahertz (THz) generation in a dual-color field was investigated experimentally by precisely controlling the relative time delay $τ$ and polarization $θ$ of dual-color lasers, where the accompanying third-harmonic generation (THG) is employed to determine $τ$ up to the sub-wavelength accuracy. An anticorrelation of the yields between THz and THG with $τ$ was displayed. Compared with the theoretical simulations, the experimental results reveal that the continuum-continuum transitions of the released electron after single-atom ionization are the dominating mechanism for THz generation, which is opposite to the high-harmonic generation (HHG) based on the recollision mechanism, or the radiation induced by perturbative bound-bound transitions.

description: We present a series of 2-dimensional hydrodynamic simulations of massive disks around protostars. We simulate the same physical problem using both a `Piecewise Parabolic Method' (PPM) code and a `Smoothed Particle Hydrodynamic' (SPH) code, and analyze their differences. The disks studied here range in mass from $0.05 M_*$ to $1.0 M_*$ and in initial minimum Toomre $Q$ value from 1.1 to 3.0. For this problem, the strengths of the codes overlap only in a limited fashion, but similarities exist in their predictions, including spiral arm pattern speeds and morphological features. Our results represent limiting cases (i.e. systems evolved isothermally) rather than true physical systems. Disks become active from the inner regions outward. From the earliest times, their evolution is a strongly dynamic process rather than a smooth progression toward eventual nonlinear behavior. We calculate approximate growth rates for the spiral patterns; the one-armed ($m=1$) spiral arm is not the fastest growing pattern of most disks. In our SPH simulations, disks with initial minimum $Q=1.5$ or lower break up into proto-binary or proto-planetary clumps. However, these simulations cannot follow the physics important for the flow and must be terminated before the system has completely evolved. At their termination, PPM simulations with similar initial conditions show uneven mass distributions within spiral arms, suggesting that clumping behavior might result if they were carried further. Concern that the point-like nature of SPH exaggerates clumping, that our representation of the gravitational potential in PPM is too coarse, and that our physics assumptions are too simple, suggest caution in interpretation of the clumping in both the disk and torus simulations.

description: We consider the following two problems: classical domain walls in the $N=1^*$ mass deformation of the maximally supersymmetric Yang Mills theory, and D-strings as external magnetic sources in the context of the AdS/CFT correspondence. We show that they are both described by Nahm's equations with unconventional boundary conditions, and analyze the relevant moduli space of solutions. We argue that general `fuzzy sphere' configurations of D-strings in AdS$_5$ correspond to Wilson-'t Hooft lines in higher representations of the dual SU(n) gauge theory.

description: In this interview, Monsignor William O'Brien discusses how he became interested in the issue of drug abuse among American youth. He describes in depth the founding of Daytop in 1963 with his associates Dr. Daniel Casriel, Joseph Shelly, and Alexander Bassin, and to what extent the program was inspired by Synanon. He discusses the transformation Daytop underwent in 1968, after splitting with its then-director David Deitch. O'Brien discusses why Daytop chose to expand into a federation of independent locations, rather than franchises. He discusses the budget and funding of Daytop, and ponders how its government funding could be subject to change in the Reagan era. He discusses his opinion of methadone maintenance and compares it to the therapeutic community model. He discusses popular critiques of the therapeutic community model. O'Brien explains what makes Daytop unique compared to other therapeutic communities such as Odyssey House and Phoenix House. He discusses the philosophy of Daytop, results they have observed in the attendees of Daytop, and why he believes the program is successful
