Inductive logic programming using bounded hypothesis space
Creators: name: Athakravi, Duangtida
Publisher: name: Imperial College London
Year: 2015

description: Inductive Logic Programming (ILP) systems apply inductive learning to an inductive learning task by deriving a hypothesis which explains the given examples. Applying ILP systems to real applications poses many challenges as they require large search space, noise is present in the learning task, and in domains such as software engineering hypotheses are required to satisfy domain specific syntactic constraints. ILP systems use language biases to define the hypothesis space, and learning can be seen as a search within the defined hypothesis space. Past systems apply search heuristics to traverse across a large hypothesis space. This is unsuitable for systems implemented using Answer Set Programming (ASP), for which scalability is a constraint as the hypothesis space will need to be grounded by the ASP solver prior to solving the learning task, making them unable to solve large learning tasks. This work explores how to learn using bounded hypothesis spaces and iterative refinement. Hypotheses that explain all examples are learnt by refining smaller partial hypotheses. This improves the scalability of ASP based systems as the learning task is split into multiple smaller manageable refinement tasks. The thesis presents how syntactic integrity constraints on the hypothesis space can be used to strengthen hypothesis selection criteria, removing hypotheses with undesirable structure. The notion of constraint-driven bias is introduced, where hypotheses are required to be acceptable with respect to the given meta-level integrity constraints. Building upon the ILP system ASPAL, the system RASPAL which learns through iterative hypothesis refinement is implemented. RASPAL's algorithm is proven, under certain assumptions, to be complete and consistent. Both systems have been applied to a case study in learning user's behaviours from data collected from their mobile usage. This demonstrates their capability for learning with noise, and the difference in their efficiency. Constraint-driven bias has been implemented for both systems, and applied to a task in specification revision, and in learning stratified programs.

A systems approach to understanding mechanisms of drug Induced mitochondrial toxicity
Creators: name: Broom, Ashley
Publisher: name: Imperial College London
Year: 2015

description: Mitochondria are important to the pharmaceutical industry. Mitochondrial perturbation is central to the aetiology of many poorly treated human diseases (e.g. neurodegenerative diseases, diabetes and cancer) and hence mitochondria are increasingly becoming therapeutic targets. However, drug-induced mitochondrial toxicity (DIMT) has also gained recognition as a significant cause of safety related attrition (including multiple post-market withdrawals). The present work ultimately aimed to discern the mechanisms downstream of DIMT in vitro and in vivo with two tool compounds which act via inhibition of the mitochondrial electron transport chain (ETC) (GSK932121A) or via uncoupling of mitochondrial oxidative phosphorylation (GSK2617971A). The first objective was to compare mitochondrial functional responses between in vitro (treatment of mitochondria isolated from control animals or in vitro cell lines) and in vivo scenarios using oxygen consumption rate (OCR) and calcium retention capacity (CRC) assays. The direction of change in these assays was often different between the in vitro and in vivo situation. Whilst seemingly contradictory, these differences reflect an adapted state in vivo which results from the initial insult in combination with compensatory changes made by the tissue to maintain energy production. In contrast, only the initial, unconfounded, response to treatment is observable in vitro. Integration of both is key to the future risk assessment of mitochondrially-active drug candidates. The second objective was to use a systems approach to build candidate adverse outcome pathways (AOP)/modes of action (MOA) for both tool compounds. AOP/MOAs were constructed based on key events observed in vivo. With both compounds, effect on body temperature, increased lactate/pyruvate ratio, gene expression changes indicative of a fasted state (induction of gluconeogenic genes) and mitochondrial ultrastructure effects were key events observed in the adverse outcome. Future work using additional compounds with mitochondrial activities would help validate the proposed AOP/MOAs. The third objective was to highlight markers of underlying mitochondrial perturbation with utility for future pre-clinical monitoring in the absence of overt DIMT. A number of mitochondrial functional changes (e.g. effect on CRC) were observed prior to the onset of overt toxicity in vivo, with both compounds and these endpoints have potential use in tailored future studies with mitochondrially-active drug candidates. These findings add to the knowledgebase on DIMT, particularly with regard to the candidate AOP/MOAs which have been postulated. This will facilitate the selection of more sensitive and functional endpoints for use in future toxicology studies with drugs where mitochondrial impairment is suspected.

description: We explore the connection between the UV luminosity functions (LFs) of high-$z$ galaxies and the distribution of stellar masses and star-formation histories (SFHs) in their host dark matter halos. We provide a baseline for a redshift-independent star-formation efficiency model to which observations and models can be compared. Our model assigns a star-formation rate (SFR) to each dark matter halo based on the growth rate of the halo and a redshift-independent star-formation efficiency. The dark matter halo accretion rate is obtained from a high-resolution $N$-body simulation in order to capture the stochasticity in accretion histories and to obtain spatial information for the distribution of galaxies. The halo mass dependence of the star-formation efficiency is calibrated at $z=4$ by requiring a match to the observed UV LF at this redshift. The model then correctly predicts the observed UV LF at $z=5-10$. We present predictions for the UV luminosity and stellar mass functions, \textit{JWST} number counts, and SFHs. In particular, we find a stellar-to-halo mass relation at $z=4-10$ that scales with halo mass at $M_{\rm h}<10^{11}~M_{\odot}$ as $M_{\star}\propto M_{\rm h}^2$, with a normalization that is higher than the relation inferred at $z=0$. The average SFRs increase as a function of time to $z=4$, although there is significant scatter around the average: about 6\% of the $z=4$ galaxies show no significant mass growth. Using these SFHs, we present redshift-dependent UV-to-SFR conversion factors, mass return fractions, and mass-to-light ratios for different intial mass functions and metallicities, finding that current estimates of the cosmic SFR density at $z\sim10$ may be overestimated by $\sim0.1-0.2~\mathrm{dex}$.

Co-operative coevolution for computational creativity: a case study In videogame design

Publisher: name: Imperial College London

description: The term procedural content generation (PCG) refers to writing software which can synthesise content for a game (or other media such as film) without further intervention from a designer. PCG has become a rich area of research in recent years, finding new ways to apply artificial intelligence to generate high-quality game content such as levels, weapons or puzzles for games. Such research is generally constrained to a single type of content, however, with the assumption that the remainder of the game's design will be fixed by an external designer. Generating many aspects of a game's design simultaneously, perhaps ultimately generating the entirety of a game's design, using PCG is not a well-explored idea. The notion of automated game design is not well-established, and is not seen as a task distinct from simply performing lots of PCG tasks at the same time. In particular, the high-level design tasks guiding the creative direction of a game are all but completely absent in PCG literature, because it is rare that a designer wishes to hand over such responsibility to a PCG system. We present here ANGELINA, an automated game designer that has developed games using a multi-faceted approach to content generation underpinned by a co-operative co-evolutionary approach which breaks down a game design into several distinct tasks, each of which controlled by an evolutionary subsystem within ANGELINA. We will show that this approach works well to automate game design, can be ported across many game engines and game genres, and can be enhanced and extended using novel computational creativity techniques to give the system a heightened sense of autonomy and independence.

description: We have detected a broad H alpha emission line in the polarized flux spectrum of the Seyfert 2 galaxy NGC 788, indicating that it contains an obscured Seyfert 1 nucleus. While such features have been observed in ~15 other Seyfert 2s, this example is unusual because it has a higher fraction of galaxy starlight in its spectrum, a lower average measured polarization, and a significantly lower radio luminosity than other hidden Seyfert 1s discovered to date. This demonstrates that polarized broad-line regions can be detected in relatively weak classical Seyfert 2s, and illustrates why well-defined, reasonably complete spectropolarimetric surveys at H alpha are necessary in order to assess whether or not all Seyfert 2s are obscured Seyfert 1s.

Hydrothermal transformations of glycerol into value-added chemicals using zeolite-based catalysts
Creators: name: Srisamai, Suna
Publisher: name: Imperial College London
Year: 2016

description: High availability and low price of crude glycerol, the main by-product of the biodiesel industry, make it an attractive feedstock for transformations into value-added chemicals. The aim of this thesis was to improve our understanding of the hydrothermal conversion of glycerol facilitated by zeolite-based catalysts. A range of Lewis acidic Ce-, La-, Sn- and Zn-doped ZSM-5 and Beta zeolites were prepared by solid state ion exchange reaction. The effect of those catalysts as well as their parent NH4- and H-forms on the dehydration of glycerol was investigated under hydrothermal conditions (270-360 °C, 55-186 bar, 5-300 min) in batch tubular reactors. Several reaction products were detected, of which acrolein was the main liquid product with the highest selectivity of ~38 mol% achieved within the first 5 min at 330 °C on H-Beta zeolite. At longer reaction times acrolein decomposed and acetaldehyde became the main product (max. selectivity ~26 mol% in 30 min). The addition of metal-doped zeolites did not increase the degree of glycerol conversion but increased the total selectivity towards the liquid products. 4.8 wt% La-doped NH4-Beta zeolite resulted in a 56 mol% glycerol conversion with a 36 mol% selectivity towards acetaldehyde. The oxidation of glycerol with H2O2 in subcritical water was investigated in a continuous fixed bed reactor at 125-175 °C, 35 bar, 60-300 s using H-Beta zeolite, 2.5 wt%- and 4.8 wt% Cu-doped H-Beta zeolite extruded with γ-Al2O3. As compared to non-catalysed oxidation, the addition of Cu-doped H-Beta zeolites did not increase the degree of conversion but promoted the conversion rate of glycerol as well as the selectivity towards liquid products. The liquid products detected included dihydroxyacetone (DHA), formic acid (FA), acetic acid, glycolic acid, pyruvaldehyde and lactic acid (LA). The distribution of these products varies with the temperature, residence time and the type of catalyst. The top-three main products obtained were DHA, FA and LA. The highest yield of DHA (~8 mol%) was achieved with 4.8 wt% Cu/H-Beta/γ-Al2O3 (MC) at 150 °C, 60 s. The same catalyst also provided LA with the highest yield of 11.5 mol% at 175 °C, 240 s. FA was detected with the highest yield of ~9 mol% at 175 °C, 60 s on H-Beta/γ-Al2O3 (MC).

description: A sample of 20 powerful extended radio galaxies with redshifts between zero and two were used to determine constraints on global cosmological parameters. Data for six radio sources were obtained from the VLA archive, analyzed, and combined with the sample of 14 radio galaxies used previously by Guerra & Daly to determine cosmological parameters. The new results are consistent with our previous results, and indicate that the current value of the mean mass density of the universe is significantly less than the critical value. A universe with $Ω_m$ in matter of unity is ruled out at 99.0% confidence, and the best fitting values of $Ω_m$ in matter are $0.10^{+0.25}_{-0.10}$ and $-0.25^{+0.35}_{-0.25}$ assuming zero space curvature and zero cosmological constant, respectively. The radio properties of each source are also used to determine the density of the gas in the vicinity of the source, and the beam power of the source. The six new radio sources have physical characteristics similar to those found for the original 14 sources. The density of the gas around these radio sources is typical of gas in present day clusters of galaxies. The beam powers are typically about $10^{45} {erg s}^{-1}$.

Beyond the Bode-Fano Bound: Wideband Impedance Matching for Short-Pulses using Temporal Switching of Transmission-Line Parameters

Year: 2018
Subjects: subject: Applied Physics (physics.app-ph)

description: Impedance matching is one of the most important practice in wave engineering as it enables to maximize the power transfer from the signal source to the load in the wave system. Unfortunately, it is bounded by the Bode-Fano criterion that states, for any passive, linear and time-invariant matching network, a stringent tradeoff between the matching-bandwidth and efficiency; implying severe constraints on various electromagnetic and acoustic wave systems. Here, we propose a matching paradigm that overcome this issue by using a temporal switching of the parameters of a metamaterial-based transmission-line, thus revoking the time-invariance assumption underlying the Bode-Fano criterion. Using this scheme we show theoretically that an efficient wideband matching, beyond Bode-Fano bound, can be achieved for short-time pulses in challenging cases of very high contrast between the load and the generator impedances, and with significant load dispersion; situations common in e.g., small antennas matching, cloaking, with applications for ultra-wideband communication, high resolution imaging, and more.

Neuronal dynamics of the anterior cingulate cortex during working memory and serotonergic manipulation
Creators: name: Golden, Caroline
Publisher: name: Imperial College London
Year: 2016

description: The prefrontal cortex (PFC) plays a strong role in the execution of executive tasks such as working memory. It is thought to exert top-down control over sensory regions, and integrate information from both external stimuli, and internal computation, such as choice and expectation (1-3). The anterior cingulate cortex (ACC) is a region of the PFC known to receive strong projections from serotonergic neurons of the raphe nuclei (4). In the work presented here, the influence of the hallucinogenic compound, and serotonergic agonist, psilocybin, was investigated in the neural circuits of the ACC of awake, head-fixed mice. Extracellular, multi-unit recordings were performed to examine the effects of the systemic administration of psilocybin. Psilocybin was found to transition the network into a desynchronised state, reminiscent of REM sleep. This state was characterised by an increase in activation in the network, combined with a reduction in power of low frequency LFP oscillations in the delta, theta and alpha band, coupled with a moderate increase in power in the gamma frequency band. The encoding mechanisms in the ACC in working memory were examined by conducting similar recordings in mice performing a delayed response task. The neuronal dynamics revealed strong encoding of low-level (stimulus information) and high-level (choice, reward anticipation) information on both a single cell and population level. The population code appeared to have strong predictive properties of task outcome that surpassed the speed at which the behavioural information could correctly classify the upcoming behavioural response. An effective method to test these hypotheses was provided in the optogenetics experiments, which perturbed the neuronal activity during the delay period of the task using channel-rhodopsin 2 (ChR2). This method proved effective and versatile in inducing a behavioural response and perturbing the neural response profiles of cells encoding information key to working memory.

description: Next generation wireless networks will exploit the large amount of spectrum available at millimeter wave (mmWave) frequencies. Design of mmWave systems, however, is challenging due to strict power, cost and hardware constraints at higher bandwidths. To achieve a good SNR for communication, mmWave systems use large antenna arrays. Beamforming with highly directional beams is one way to use the antennas. As the channel changes over time, the beams that maximize the SNR have to be estimated quickly to reduce the training overhead. Prior work has exploited the observation that mmWave channels are sparse to perform compressed sensing (CS) based beam alignment with few channel measurements. Most of the existing CS-based algorithms, however, assume perfect synchronization and fail in the presence of carrier frequency offset (CFO). This paper presents Swift-Link, a fast beam alignment algorithm that is robust against the offset. Swift-Link includes a novel randomized beam training sequence that minimizes the beam alignment errors due to CFO and a low-complexity algorithm that corrects these errors. Even with strict hardware constraints, our algorithm uses fewer channel measurements than comparable CS algorithms and has analytical guarantees. Swift-Link requires a small output dynamic range at the analog-to-digital converter compared to beam-scanning techniques.

description: Multi-frequency radio observations of the radio bridge of powerful classical double radio sources can be used to determine: the beam power of the jets emanating from the AGN; the total time the source will actively produce jets that power large-scale radio emission; the thermal pressure of the medium in the vicinity of the radio source; and the total mass, including dark matter, of the galaxy or cluster of galaxies traced by the ambient gas that surrounds the radio source. The theoretical constructs that allow a determination of each of these quantities using radio observations are presented and discussed. Empirical determinations of each of these quantities are obtained and analyzed. A sample of 14 radio galaxies and 8 radio loud quasars with redshifts between zero and two for which there is enough radio information to be able to determine the physical parameters listed above was studied in detail.

Robust model predictive control: robust control invariant sets and efficient implementation
Creators: name: Liu, Chengyuan
Publisher: name: Imperial College London
Year: 2017

description: Robust model predictive control (RMPC) is widely used in industry. However, the online computational burden of this algorithm restricts its development and application to systems with relatively slow dynamics. We investigate this problem in this thesis with the overall aim of reducing the online computational burden and improving the online efficiency. In RMPC schemes, robust control invariant (RCI) sets are vitally important in dealing with constraints and providing stability. They can be used as terminal (invariant) sets in RMPC schemes to reduce the online computational burden and ensure stability simultaneously. To this end, we present a novel algorithm for the computation of full-complexity polytopic RCI sets, and the corresponding feedback control law, for linear discrete-time systems subject to output and initial state constraints, performance bounds, and bounded additive disturbances. Two types of uncertainty, structured norm-bounded and polytopic uncertainty, are considered. These algorithms are then extended to deal with systems subject to asymmetric initial state and output constraints. Furthermore, the concept of RCI sets can be extended to invariant tubes, which are fundamental elements in tube based RMPC scheme. The online computational burden of tube based RMPC schemes is largely reduced to the same level as model predictive control for nominal systems. However, it is important that the constraint tightening that is needed is not excessive, otherwise the performance of the MPC design may deteriorate, and there may even not exist a feasible control law. Here, the algorithms we proposed for RCI set approximations are extended and applied to the problem of reducing the constraint tightening in tube based RMPC schemes. In order to ameliorate the computational complexity of the online RMPC algorithms, we propose an online-offline RMPC method, where a causal state feedback structure on the controller is considered. In order to improve the efficiency of the online computation, we calculate the state feedback gain offline using a semi-definite program (SDP). Then we propose a novel method to compute the control perturbation component online. The online optimization problem is derived using Farkas' Theorem, and then approximated by a quadratic program (QP) to reduce the online computational burden. A further approximation is made to derive a simplified online optimization problem, which results in a large reduction in the number of variables. Numerical examples are provided that demonstrate the advantages of all our proposed algorithms over current schemes.

description: Let $α$, $β$, $γ, \dots$ $Θ$, $Ψ, \dots$ $R$, $S$, $T, \dots$ be variables for, respectively, congruences, tolerances and reflexive admissible relations. Let juxtaposition denote intersection. We show that if the identity $α(β\circ Θ) \subseteq αβ\circ αΘ\circ αβ$ holds in a variety $\mathcal {V}$, then $\mathcal {V}$ has a majority term, equivalently, $\mathcal {V}$ satisfies $ α(β\circ γ) \subseteq αβ\circ αγ$. The result is unexpected, since in the displayed identity we have one more factor on the right and, moreover, if we let $Θ$ be a congruence, we get a condition equivalent to $3$-distributivity, which is well-known to be strictly weaker than the existence of a majority term. The above result is optimal in many senses, for example, we show that slight variations on the displayed identity, such as $ R (S \circ γ) \subseteq R S \circ R γ\circ R S$ or $R(S \circ T) \subseteq R S \circ RT \circ RT \circ RS$ hold in every $3$-distributive variety. Similar identities are valid even in varieties with $2$ Gumm terms, with no distributivity assumption. We also discuss relation identities in $n$-permutable varieties and present a few remarks about implication algebras.

Studies on the epoxidation of bromoallenes, biomimetic transannular rearrangements and the total synthesis of members of the Laurencia natural product family
Creators: name: Clarke, James
Publisher: name: Imperial College London
Year: 2016

description: The research presented here regards the biosynthetic origins of several secondary metabolites isolated from red algae of the genus Laurencia. This thesis has been separated into two major parts, and includes an appendix cataloguing the experimental procedures and spectroscopic data. Part I covers the epoxidation of bromoallenes, as inspired by the previously unknown biosynthetic link between two natural products isolated from Laurencia obtusa, one bearing a bromoallene and the other an α,β-unsaturated ester. Employing model bromoallene 1 and a range of epoxidation methods, a procedure was developed that would generate α,β-unsaturated acids 2 in low, but reproducible yields. Isotopic labelling of the substrate with deuterium and carbon-13 allowed elucidation of the mechanism, by observation of the migration of these atoms.Part II of this thesis reports the completion of the total synthesis of a range of Laurencia secondary metabolites. The initial targets of this project proved to be unobtainable, most likely due to the sensitivity of the allyl ether group under reductive conditions. An alternative route was successfully applied to bypass this problematic step, allow the synthesis of a range of Laurencia natural products and provide insights into their biosynthesis. Positive identification of these compounds was achieved by a Δδ analysis of the collected 1H & 13C NMR spectra, with that reported in literature.

description: The majority of bright distant quasars $(z {}^{>}_{\sim} 1)$ may form in massive mergers appearing in compact galaxy groups in/and young clusters. The expected tests are (i) large correlation signal for medium-$z$ QSOs $(1 < z < 2)$ and (ii) direct search for quasar groups (QGs) indicating positions of distant pre-superclusters which later will evolve to the "systems" like the local Great Attractor or Shapley concentration. We discuss large QGs with more than ten members within regions $\le l_{LS} \sim 100-150 \, h^{-1} Mpc$, tracing the enhanced density regions at $z {}^{

An FFT-based Solution Method for the Poisson Equation on 3D Spherical Polar Grids

description: The solution of the Poisson equation is a ubiquitous problem in computational astrophysics. Most notably, the treatment of self-gravitating flows involves the Poisson equation for the gravitational field. In hydrodynamics codes using spherical polar grids, one often resorts to a truncated spherical harmonics expansion for an approximate solution. Here we present a non-iterative method that is similar in spirit, but uses the full set of eigenfunctions of the discretized Laplacian to obtain an exact solution of the discretized Poisson equation. This allows the solver to handle density distributions for which the truncated multipole expansion fails, such as off-center point masses. In three dimensions, the operation count of the new method is competitive with a naive implementation of the truncated spherical harmonics expansion with $N_\ell \approx 15$ multipoles. We also discuss the parallel implementation of the algorithm. The serial code and a template for the parallel solver are made publicly available.

Lead-based materials for energy applications
Creators: name: Poll, Christopher
Publisher: name: Imperial College London
Year: 2015

description: Lead has long been a ubiquitous material within the energy industry, with use in the classic lead acid batteries (PbO2 and PbSO4), lead telluride thermoelectrics, and the emerging class of lead perovskite photovoltaics. Photoactive films of highly (110) orientated alpha-PbO have been synthesised through the electrochemical oxidation of Pb foil. Using a combination of electrochemical growth and x-ray diffraction the growth of these films has been understood as developing from beta-PbO through to highly (110) orientated alpha-PbO as the growth time progresses. This orientation has further been understood as only developing in an out-of-plane manner, with no preferred in-plane orientation observed. PbO2 films have been electroplated onto transparent conducting oxides. A thermal reduction method has been used to reduce these films to Pb3O4, beta-PbO and alpha-PbO. The thermal reduction of PbO2 has been studied in situ using high pressure photoelectron spectroscopy (HiPPES). HiPPES measurements of PbO2 have also yielded results suggesting oxygen vacancy healing in the material. Deep eutectic solvents (DES) have demonstrated excellent application to the recycling of lead-based energy materials. By dissolving the spent material in a DES, the toxic Pb can be selectively electrodeposited out. The technique shows a means for environmentally friendly recycling of lead acid batteries and for lead perovskite solar cells, overcoming one of the main prohibitive steps preventing their marketplace integration. The electronic structure of PbTe has been studied through a combination of hard x-ray photoelectron spectroscopy (HAXPES), soft x-ray photoelectron spectroscopy (SXPS) and density function theory calculations. The results have yielded a thorough understanding of the electronic structure of the PbTe valence band due to the high resolution of the photoelectron spectra and the calculated partial density of states. Using the varying probing depths of HAXPES and SXPS an upward surface band-bending of 0.26 eV has been observed, closely matching theoretical predictions.
IRAS 23385+6053: A Prototype Massive Class 0 Object

description: IRAS 23385+6053 is a Young Stellar Object with luminosity 16,000 solar luminosities at a kinematic distance of 4.9 kpc. This candidate precursor of an ultracompact HII region is associated with a millimeter source detected at the JCMT but is undetected at centimeter wavelengths with the VLA. We observed this source with the OVRO millimeter array at 3.4 mm in the continuum, HCO+(1-0), H13CO+(1-0) and SiO(v=0, 2-1) line emission, and with CAM aboard ISO at 6.75 and 15 um. The IRAS source is coincident with a 3.4 mm compact (r~0.048 pc) and massive (M~370 solar masses) core, which is undetected at 15 um to a 3 sigma level of 6 mJy; this is compatible with the derived H2 column density of 2x10(24) and the estimated visual extinction of about 2000 mag. We find L(submm)/L(bol)>10(-3) and M(env)/M(star)>>1, typical of Class 0 objects. The source is also associated with a compact outflow characterized by a size similar to the core radius, a dynamical timescale of about 7,000 years, and a mass loss rate of about 10(-3) solar masses/year. The axis of the outflow is oriented nearly perpendicular to the plane of the sky, ruling out the possibility that the non-detection at 15 um is the result of a geometric effect. All these properties suggest that IRAS 23385+6053 is the first example of a bona fide massive Class 0 object.
THE POLARIZED SPECTRUM OF THE FE II-RICH BAL QSO, IRAS 07598+6508

description: We present IUE spectrophotometry and optical spectropolarimetry of the ultraluminous, extreme FeII-emitting QSO IRAS 07598+6508. We find broad absorption troughs from high- and low-ionization species, showing that this object is a member of the class of rare low-ionization BAL QSOs. Compared with non-BAL QSOs, the spectral energy distribution is reddened by E(B-V) sim 0.12, and the Halpha/Hbeta ratio even more reddened with E(B - V) sim 0.45. The broad emission lines are unpolarized. We see broad Na I lambda5892 absorption in the unpolarized continuum, but not in the polarized continuum (at the 5-6 sigma level). The polarized continuum rises smoothly towards shorter wavelengths with F_lambda propto lambda{-2}. We argue that a normal QSO continuum is polarized by scattering from a region within, or very near, the Broad Emission Line Region (BELR). Thus there are at least three distinct light paths to the observer: a dusty path from the BELR, a direct path traced by the unpolarized continuum, passing through dust and low-ionization gas (NaI), and another relatively unobscured path followed by scattered continuum. This provides direct evidence that a BAL region and dust only partially cover the central QSO. Ultraluminous AGNs, including IRAS 07598+6508, appear no more IR-luminous than non-IRAS-selected QSOs, and have normal L(IR)/L(opt) ratios when the optical luminosities are corrected for reddening. Reddening and BALs occur only along some sight lines and the parent population of BALQs are `normal' QSOs.

Reprocessing of radiation by multi-phase gas in Low Luminosity Accretion Flows

description: We discuss the role that magnetic fields in low luminosity accretion flows can play in creating and maintaining a multi-phase medium, and show that small magnetically-confined clouds or filaments of dense cold gas can dramatically reprocess the `primary' radiation from tori. In particular, radio emission would be suppressed by free-free absorption, and an extra (weak) component would appear at optical wavelengths. This is expected to be a common process in various environments in the central regions of Active Galaxies, such as broad line regions, accretion disk coronae and jets.
