Are the Nuclei of Seyfert 2 Galaxies Viewed Face-On?

description: We show from modeling the Fe Kalpha line in the ASCA spectra of four X-ray bright narrow emission line galaxies (Seyfert types 1.9 and 2) that two equally viable physical models can describe the observed line profile. The first is discussed by Turner et al. (1998) and consists of emission from a nearly pole-on accretion disk. The second, which is statistically preferred, is a superposition of emission from an accretion disk viewed at an intermediate inclination of about 48 degrees and a distinct, unresolved feature that presumably originates some distance from the galaxy nucleus. The intermediate inclination is entirely consistent with unified schemes and our findings challenge recent assertions that Seyfert 2 galaxies are preferentially viewed with their inner regions face-on. We derive mean equivalent widths for the narrow and disk lines of =60 eV and = 213 eV, respectively. The X-ray data are well described by a geometry in which our view of the active nucleus intersects and is blocked by the outer edges of the obscuring torus, and therefore do not require severe misalignments between the accretion disk and the torus.

Rapid infection diagnostics in the context of augmented care: Investigating their role in antimicrobial prescribing and bacterial resistance
Creators: name: Moore, Luke Stephen Prockter
Publisher: name: Imperial College London
Year: 2016

description: Introduction: Augmented care is a potentially significant reservoir of antimicrobial resistance (AMR). In the context of augmented care, this thesis investigates AMR variation and its drivers, barriers to optimising antimicrobial use, and the role of rapid infection-related diagnostics in addressing this. Methods: Mixed methods were used. AMR and antimicrobial consumption were quantitatively analysed, and driving factors explored using (i) statistical algorithms and (ii) thematic analysis of semi-structured interviews. As a case study, the role of rapid microbiology diagnostics was investigated with interrupted time series analysis of introduction of matrix-assisted laser desorption/ionisation time-of-flight (MALDI-ToF). The added value of computerised decision support was then assessed. Results: Analysis of 174,434 isolates demonstrated significant AMR variation between and within hospitals, with an excess in augmented care. Multiple ‘mini-outbreaks’ partly account for this, as does variation in antimicrobial consumption. Communication, knowledge, and personalisation of prescribing significantly influence the latter. Microbiology results are suboptimally utilised in these three areas. MALDI-ToF introduction, as a case study of a rapid microbiology diagnostic, significantly improved bacterial identification, but did not alter antimicrobial consumption. A role in surveillance is apparent, through identifying and investigating outbreaks, and in infection control, through carbapenemase detection. A computerised decision support system, derived from analysis of augmented care antimicrobial prescribing, facilitates wider impact from such rapid microbiology diagnostics. Conclusion: Augmented care areas have high, yet heterogeneous, levels of AMR, in part due to previously undetected outbreaks, and in part from variation in prescribing. Lost opportunities in communication, personalisation, and knowledge-holding influence the latter. Increasing the rapidity and specificity of microbial identification plays only a limited role in antimicrobial stewardship, but wider roles in surveillance and infection control will further impact AMR in augmented care. Decision support systems add further value, facilitating integration of clinical data, and shaping empiric antimicrobial choice where results are not available.

description: We investigate stationary rotationally symmetric solutions of a particular truncation of Horndeski theory in three dimensions, including a non-minimal scalar kinetic coupling to the curvature. After discussing the special case of a vanishing scalar charge, which includes most of the previously known solutions, we reduce the general case to an effective mechanical model in a three-dimensional target space. We analyze the possible near-horizon behaviors, and conclude that black hole solutions with degenerate horizons and constant curvature asymptotics may exist if the minimal and non-minimal scalar coupling constants have the same sign. In a special case, we find a new analytic rotating black hole solution with scalar hair and degenerate horizon. This is geodesically and causally complete, and asymptotic to the extreme BTZ metric. We also briefly discuss soliton solutions in another special case.

Exploring the influence of bioactive glasses on stem cell chondrogenesis for tissue engineering
Creators: name: Littmann, Elena
Publisher: name: Imperial College London
Year: 2016

description: The development of smart biomaterials which trigger the differentiation of progenitor cells towards a desired lineage continues to pose a challenge for the material science and tissue engineering communities. In order to design such materials, a better understanding of cell-material interactions as well as knowledge of the key physico-chemical parameters responsible for the determination of cell fate are essential. Bioactive glasses are attractive materials for osteochondral repair applications and are known to impact cell behaviour. Characteristically, bioactive glasses modify their local ionic microenvironment by releasing therapeutic ions when introduced in biological fluids. Such bioactive glass extracts have been shown to trigger specific biological responses in vitro and in vivo. This thesis explores the influence of key bioactive ion species within bioactive glass dissolution products on the behaviour of human mesenchymal stem cells (hMSCs). Firstly, the effect of strontium ions within bioactive glass extracts on metabolic processes in hMSCs is studied following a non-biased approach based on a whole genome mRNA microarray. It is demonstrated that such extracts induce an up-regulation of the isoprenoid biosynthesis pathway in hMSCs causing a multifactorial response beyond lineage commitment opening up new avenues of evaluating cell-material interactions. Secondly, to identify desirable glass compositions for the repair of the osteochondral system, the influence of strontium and/ or magnesium containing bioactive glasses on hMSC chondrogenic differentiation is investigated. Bioactive glass extracts are shown to differentially modify cartilaginous matrix accumulation in hMSC pellets in a composition-dependent manner. Finally, insights into the impact of the hypoxia-mimicking agent cobalt within bioactive glass extracts on hMSC chondrogenic differentiation and (stem) cell behaviour are explored. It is demonstrated that hMSC chondrogenesis in presence of bioactive glass extracts is cobalt dose-dependently reduced. Collectively, the work described in this thesis has contributed to defining the impact of key ions on hMSC behaviour.

description: We report the first detection of a hard power-law tail in the X-ray spectrum of the black hole candidate (BHC) binary X1755-338, which was observed in 1989 March-September during the TTM Galactic Centre survey. In addition, an ultrasoft thermal component with a temperature of ~1.1-1.4 keV was also detected. We demonstrate that the soft and hard X-ray components of X1755-338 vary independently, as in the spectra of the well known BHCs LMC X-1, LMC X-3 and GX339-4 in their high (intensity) state. If the hard tail observed from X1755-338 is generated near the black hole by energetic electrons up-scattering low energy photons, the un-correlated variations imply that the soft X-rays from accretion disc may not be the main photon seeds needed for inverse Comptonization. The TTM observations strongly suggest that X1755-338 does indeed belong to the family of BHCs.

title: The watchman's walk problem on directed graphs.
Creators: name: Pittman, Brittany
Publisher: name: Memorial University of Newofundland

description: A watchman’s walk in a graph is a minimum closed dominating walk. Given a graph and a single watchman, the aim of the Watchman’s walk problem is to find a shortest closed walk that allows the guard to efficiently monitor all vertices in the graph. In a directed graph, a watchman’s walk must obey the direction of the arcs. In this case, we say that the guard can only move to and see the vertices that are adjacent to him relative to outgoing arcs. In this thesis, we consider the watchman’s walk problem on directed graphs. In particular, we study the problem on tournaments, orientations of complete bipartite and multipartite graphs, and directed graphs formed from sequences.
Suppression of Tearing Modes by RF Current Condensation

description: Currents driven by rf (radio frequency) waves in the interior of magnetic islands can stabilize deleterious tearing modes in tokamaks. Present analyses of stabilization assume that the local electron acceleration is unaffected by the presence of the island. However, the power deposition and electron acceleration are sensitive to the perturbation of the temperature. The nonlinear feedback on the power deposition in the island increases the temperature perturbation, and can lead to a bifurcation of the solution to the steady-state heat diffusion equation. The combination of the nonlinearly enhanced temperature perturbation with the rf current drive sensitivity to the temperature leads to an rf current condensation effect, which can increase the efficiency of rf current drive stabilization and reduce its sensitivity to radial misalignment of the ray trajectories. The threshold for the effect is in a regime that has been encountered in experiments, and will likely be encountered in ITER.

description: We consider a model of axisymmetric neutron star magnetosphere. In our approach, the current density in the region of open field lines is constant and the returning current flows in a narrow layer along the separatrix. In this case, the stream equation describing the magnetic field structure is linear both in the open and closed regions, the main problem lying in matching the solutions along the separatrix (Okamoto 1974; Lyubarskii 1990). We demonstrate that it is the stability condition on the separatrix that allows us to obtain a unique solution of the problem. In particular, the zero point of magnetic field is shown to locate near the light cylinder. Moreover, the hypothesis of the existence of the nonlinear Ohm's Law (Beskin, Gurevich & Istomin 1983) connecting the potential drop in the pair creation region and the longitudinal electric current flowing in the magnetosphere is confirmed.

A Viewing Angle - Kinetic Luminosity Unification Scheme For BL Lacertae Objects

Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)

description: We propose a unified classification for BL Lac objects (BLs), focusing on the synchrotron peak frequency of the spectral energy distribution. The unification scheme is based on the angle Theta that describes the orientation of the relativistic jet and on the electron kinetic luminosity Lambda of the jet. We assume that Lambda scales with the size of the jet r in a self-similar fashion (Lambda propto r^2), as supported by observational data. The jets are self-similar in geometry and have the same pressure and median magnetic field at the inlet, independent of size. The self-similarity is broken for the highest energy electrons, which radiate mainly at high frequencies, since for large sources they suffer more severe radiative energy losses over a given fraction of the jet length. We calculate the optically thin synchrotron spectrum using an accelerating inner jet model based on simple relativistic gas dynamics and show that it can fit the observed infrared to X-ray spectrum of PKS 2155--304. We couple the accelerating jet model to the unification scheme and compare the results to complete samples of BLs. The negative apparent evolution of X-ray selected BLs is explained as a result of positive evolution of the jet electron kinetic luminosity $Λ_{kin}$. We review observational arguments in favor of the existence of scaled-down accretion disks and broad emission-line regions in BLs. The proposed unification scheme can explain the lack of observed broad emission lines in X-ray selected BLs, as well as the existence of those lines preferentially in luminous radio-selected BLs. Finally, we review observational arguments that suggest the extension of this unification scheme to all blazars.

description: Onychomycosis is a fungal infection of nails that is widespread and difficult to treat because of the impermeable nature of human nails. Topically applied anti-fungal agents cannot penetrate this structure, and treatment regimens often resort to systemic antifungals with concomitant side effects. One recent clinical study suggested that mechanical fenestration of the nail using an intelligent nail drill might be a possible solution to this problem. In this work, an in vitro model of the transungual delivery of antifungal agents is presented, which utilizes real nail tissue and an inline flow system. This system was deployed to measure transungual delivery of ciclopirox and determined that nail fenestration improved drug delivery by 3–4-fold after 42 days. This study bolsters the argument that nail fenestration should be accepted as a pretreatment for onychomycosis and offers a way of evaluating new drugs or formulations designed to combat this condition. The in vitro model described herein would be an excellent system to directly measure transungual delivery of antifungal agents prior to clinical trials.
Macrophage plasticity in chronic obstructive pulmonary disease
Creators: name: Day, Amy
Publisher: name: Imperial College London
Year: 2016

description: Macrophages respond to their microenvironment by altering phenotype. In response to chronic pro-inflammatory signals, such as those in chronic obstructive pulmonary disease (COPD) macrophages can become skewed towards a pro-inflammatory phenotype. However, macrophages are important in the resolution of inflammation and consequently need to alter their phenotype to maintain homeostasis. COPD is a chronic inflammatory condition and therefore the hypothesis of this thesis is that macrophages from COPD patients have lost their ability to alter phenotype and lack plasticity. This thesis used monocyte derived macrophages (MDM) from non-smokers, smokers and COPD patients differentiated in either GM-CSF (GM-MDM) or M-CSF (M-MDM). It also explored plasticity of these cells through manipulation of culture environment. The response of these cells to LPS and IL-4 stimulation showed GM-MDM were more pro-inflammatory and less able to phagocytose bacteria compared with M-MDM in non-smokers. It also showed that MDM from COPD patients were more pro-inflammatory and less phagocytic regardless of environment. However, cell surface receptors alone were insufficient at defining phenotype. While MDM from non-smokers were able to alter phenotype in response to environmental change, MDM from COPD patients only became more pro-inflammatory, demonstrating unidirectional plasticity. Analysis of monocyte subsets within whole blood showed no significant differences between subject groups, suggesting differences in MDM phenotype occur during differentiation. MDM from COPD patients expressed higher levels of pro-inflammatory-linked transcription factors compared with non-smokers and were less able to alter this expression in response to environmental changes, again demonstrating a lack in plasticity in these cells. MDM from COPD patients lack ability to alter phenotype in response to environmental change, demonstrating a lack of plasticity which accentuates the pro-inflammatory COPD phenotype.
Kinetic Mixing, Dark Photons and Extra Dimensions II: Fermionic Dark Matter

Publisher: name: arXiv
Year: 2018
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Extra dimensions can be very useful tools when constructing new physics models. Previously, we began investigating toy models for the 5-D analog of the kinetic mixing/vector portal scenario where the interactions of bulk dark matter with the brane-localized fields of the Standard Model are mediated by a massive $U(1)_D$ dark photon also living in the bulk. In that setup, where the dark matter was taken to be a complex scalar, a number of nice features were obtained such as $U(1)_D$ breaking by boundary conditions without the introduction of a dark Higgs field, the absence of potentially troublesome SM Higgs-dark singlet mixing, also by boundary conditions, the natural similarity of the dark matter and dark photon masses and the decoupling of the heavy gauge Kaluza-Klein states from the Standard Model. In the present paper we extend this approach by examining the more complex cases of Dirac and Majorana fermionic dark matter. In particular, we discuss a new mechanism that can occur in 5-D (but not in 4-D) that allows for light Dirac dark matter in the $\sim 100$ MeV mass range, even though it has an $s$-wave annihilation into Standard Model fields, by avoiding the strong constraints that arise from both the CMB and 21 cm data. This mechanism makes use of the presence of the Kaluza-Klein excitations of the dark photon to extremize the increase in the annihilation cross section usually obtained via resonant enhancement. In the Majorana dark matter case, we explore the possibility of a direct $s$-channel dark matter pair-annihilation process producing the observed relic density, due to the general presence of parity-violating dark matter interactions, without employing the usual co-annihilation mechanism which is naturally suppressed in this 5-D setup.

Fourteen objects (0.52%) do not have redshifts. The survey covers 87.6% of the sky. The data for the complete 1.2 Jy survey (the data presented here in addition to that of Strauss \etal 1992) may be obtained in a machine-readable form from the National Space Science Data Center and from the anonymous ftp site given above.

Moreover, we point out a strikingly different dependence of the multiplicity per participant on $N_\text{part}$ in p+Pb vs.\ Pb+Pb collisions at LHC energies, and argue that the observed behavior follows rather naturally from the convolution of the gluon distributions of an asymmetric vs. symmetric projectile and target.

description: We report on the discovery of a highly luminous, broad absorption line quasar at a redshift of $z=3.87$ which is positionally coincident, within one arcsecond, with the IRAS FSC source F08279+5255. A chance alignment of the quasar and the IRAS source is extremely unlikely and we argue that the optical and FIR flux are different manifestations of the same object. With an R-band magnitude of 15.2, and an IRAS 60$\mum$ flux of $0.51\jy$, APM 08279+5255 is (apparently) easily the most intrinsically luminous object known, with $ L_{Bol}\sim5\times10^{15}L_{\odot}}$. Imaging suggests that gravitational lensing may play a role in amplifying the intrinsic properties of the system. The optical spectrum of the quasar clearly reveals the presence of three potential lensing galaxies, \mg absorption systems at $z=1.18$ and $z=1.81$, and a \ly absorption system at $z=3.07$. We estimate the total amplification of the optical component to be $\approx40$, but, due to the larger scale of the emitting region, would expect the infrared amplification to be significantly less. Even making the conservative assumption that all wavelengths are amplified by a factor 40, APM 08279+5255 still possesses a phenomenal luminosity of $\simgt 10^{14L_{\odot}}$, indicating that it belongs to a small, but significant population of high--redshift, hyperluminous objects with copious infrared emission.

Reverse-engineering the visual and haptic perceptual algorithms in the brain
Creators: name: Behbahani, Feryal Mehraban Pour
Publisher: name: Imperial College London
Year: 2016

description: Intelligent behaviour is fundamentally tied to the ability of the brain to make decisions in uncertain and dynamic environments. To accomplish this task successfully, the brain needs to categorise novel stimuli in real-time. In neuroscience, the generative framework of Bayesian Decision Theory has emerged as a principled way to predict how the brain has to act in the face of uncertainty. We sought to investigate whether the brain also uses generative Bayesian principles to implement its categorisation strategy. To this end, by adopting tools from machine learning as a quantitative framework, we reverse-engineered a novel experimental paradigm which allowed us to directly test this hypothesis in a variety of visual object categorisation tasks. In addition, our results provide new implications for existing models of human category learning and provide an ideal experimental paradigm for neurophysiological and functional imaging investigations of the underlying neural mechanisms involved in object recognition. We also turn to the problem of haptic object recognition by building on the belief that its underlying algorithms should resemble that of vision. Accordingly, we present a Bayesian ideal observer model for human haptic perception and object reconstruction which infers from contact point information on the surface of the hand and noisy hand proprioception, simultaneously the shape of the object together with an estimation of the true hand pose in space. We implement this theory using a recursive Bayesian estimation algorithm, inspired by the simultaneous localisation and mapping (SLAM) methods in robotics, which can operate on experimental data from human subjects as well as computer-based physical simulations. Our work enables the principled study of the haptic perception of complex objects and scenes in a similar principled manner that transformed research in the field of vision. Moreover, in conjunction with tactile-enabled prostheses, our model could allow for online object recognition and pose adaptation for more natural prosthetic control.
Automated Playtesting on 2D Video Games, an Agent-based Approach on NethackClone Game via Iv4XR Framework

description: In the current project we present our study on automated video game testing. For our research, we apply our approach of automated agent-based testing, on NethackClone, a 2D, grid-based video game. Our implementation utilizes the Iv4xr framework, a tool that is able to apply and generalize automated testing on multiple types of video games, enabling us in that way to perform agent-based testing on the game, by creating agents and assigning goals to them. Alongside the testing tasks we implemented for our project, we also perform a number of checks on the SUT, checking whether the game behaves as intended when specific actions take place in it. Checks are related to the interaction between the player and the main elements of the game. We created two different tests, with 7 goals and more than 25 actions, tactics and utilities, running our experiments on a total of 307 unique test cases (171 on Test 1, 136 for Test 2). We evaluated our approach based on 3 main factors: coverage, success ratio and time, while the time and effort the framework needs to adapt for a new game each time is also of interest to us. Results derived through the experiments proved not only that our approach performs efficiently at a considerable level, but also our system was even able to detect an actual, unknown bug in the game. The functionality and the ability of the framework to adjust and generalize for multiple games is also promising, considering factors such as updates and adjustments on a game, or similarities between video games. The effort and time we devoted to the framework proved out to be a one-time investment, as once the integration of the SUT into the framework is complete, it can be repeatedly used for creating new testing tasks, checking on different assets of the game. In this way it can assist testers save important time and effort in further, future tests on the same SUT. However, our study also pointed out existing malfunctions in our approach, since our research was limited in terms of time and computational power, proving the need for extended research on a huge number of tests and test cases, in possible future studies.

description: We present a detailed theoretical description of an atomic scanning microscope in a cavity QED setup proposed in Phys. Rev. Lett. 120, 133601 (2018). The microscope continuously observes atomic densities with optical subwavelength resolution in a nondestructive way. The super-resolution is achieved by engineering an internal atomic dark state with a sharp spatial variation of population of a ground level dispersively coupled to the cavity field. Thus, the atomic position encoded in the internal state is revealed as a phase shift of the light reflected from the cavity in a homodyne experiment. Our theoretical description of the microscope operation is based on the stochastic master equation describing the conditional time evolution of the atomic system under continuous observation as a competition between dynamics induced by the Hamiltonian of the system, decoherence effects due to atomic spontaneous decay, and the measurement backaction. Within our approach we relate the observed homodyne current with a local atomic density, and discuss the emergence of a quantum nondemolition measurement regime allowing continuous observation of spatial densities of quantum motional eigenstates without measurement backaction in a single experimental run.

description: Faithfully transferring the quantum state is essential for quantum information processing. Here we demonstrate a fast (in 84 ns) and high-fidelity (99.2%) transfer of arbitrary quantum states in a chain of four superconducting qubits with nearest-neighbor coupling. This transfer relies on full control of the effective couplings between neighboring qubits, which is realized only by our parametrically modulating the qubits without increasing circuit complexity. Once the couplings between qubits fulfill a specific ratio, perfect quantum state transfer can be achieved in a single step, and is therefore robust to noise and accumulation of experimental errors. This quantum state transfer can be extended to a larger qubit chain and thus adds a desirable tool for future quantum information processing. The demonstrated flexibility of the coupling tunability is suitable for quantum simulation of many-body physics, which requires different configurations of qubit couplings.

The White Dwarf Cooling Age of M67

description: A deep imaging survey covering the entire $23\arcmin$ diameter of the old open cluster M67 to $V = 25$ has been carried out using the mosaic imager (UHCam) on the Canada-France-Hawaii Telescope. The cluster color-magnitude diagram (CMD) can be traced from stars on its giant branch at $M_{V} = +1$ down through main sequence stars at least as faint as $M_{V} = 13.5$. Stars this low in luminosity have masses below $0.15 M_{\odot}$. A modest white dwarf (WD) cooling sequence is also observed commencing slightly fainter than $M_V = 10$ and, after correction for background galaxy and stellar field contamination, terminating near $M_V = 14.6$. The observed WDs follow quite closely a theoretical cooling sequence for $0.7 M_{\odot}$ pure carbon core WDs with hydrogen-rich atmospheres (DA WDs). The cooling time to an $M_V$ of 14.6 for such WDs is 4.3 Gyr which we take as the WD cooling age of the cluster. A fit of a set of isochrones to the cluster CMD indicates a turnoff age of 4.0 Gyr. The excellent agreement between these results suggests that ages derived from white dwarf cooling should be considered as reliable as those from other dating techniques. The WDs currently contribute about 9% of the total cluster mass but the number seen appears to be somewhat low when compared with the number of giants observed in the cluster.

TEMPERATURE DISTRIBUTION FUNCTION OF X-RAY CLUSTERS OF GALAXIES IN A NEUTRINO DOMINATED UNIVERSE

description: The temperature distribution function (TDF) of X-ray clusters is derived for different normalizations of the HDM power spectrum in an Omega_0=1 universe using the statistics of peaks of a random Gaussian field. Concerning cluster formation only, the neutrino picture appears to be marginally consistent with observations for H_0=70 km/s/Mpc provided the normalization is alpha=sigma_0/delta_s=0.42 with sigma_0 the rms variance of the fluctuations linearly evolved to the present epoch and delta_s the collapse threshold required in structure formation models. However, using the constraint that the formation epoch of QSO's puts on the HDM model, it appears that this normalization is too small to be consistent with quasars formation. Allowing higher values for the Hubble constant alleviates this problem but leads to an unacceptable short age of the universe. Moreover, the constraint put by the recent measurement of the level of fluctuations in the cosmic background radiation by COBE tends to reject models with high values of H_0. We conclude that the neutrino model fails in any case to account for the whole set of available observations in a consistent way.
