description: We study the dynamics and evolution of the Milky Way nuclear star cluster performing a high resolution direct one-million-body simulation. Focusing on the interactions between such stellar system and the central supermassive black hole, we find that different stellar components adapt their overall distribution differently. After 5 Gyr, stellar mass black holes are characterized by a spatial distribution with power-slope $-1.75$, fully consistent with the prediction of Bahcall-Wolf pioneering work. Using the vast amount of data available, we infer the rate for tidal disruption events, being $4 \times 10^{-6}$ per yr, and estimate the number of objects that emit gravitational waves during the phases preceding the accretion onto the super-massive black hole, $\sim 270$ per Gyr. We show that some of these sources could form extreme mass-ratio inspirals. We follow the evolution of binary stars population, showing that the initial binary fraction of $5\%$ drops down to $2.5\%$ inside the inner parsec. Also, we explored the possible formation of binary systems containing a compact object, discussing the implications for millisecond pulsars formation and the development of Ia Supernovae.

description: Like many developing countries, Nigeria, is faced with a number of tradeoffs that pit rapid economic development against environmental preservation. Environmentally sustainable,``green" economic development is slower, more costly, and more difficult than unrestricted, unregulated economic growth. The mathematical model that we develop in this paper suggests that widespread public awareness of environmental issues is insufficient to prevent the tendency towards sacrificing the environment for the sake of growth. Even if people have an understanding of negative impacts and always choose to act in their own self-interest, they may still act collectively in such a way as to bring down the quality of life for the entire society. We conclude that besides raising public awareness, economic intervention by the government (in the form of incentives or penalties) may be the only way to achieve an optimal balance between economic and environmental factors.

description: We consider the problem of decentralized consensus optimization, where the sum of $n$ smooth and strongly convex functions are minimized over $n$ distributed agents that form a connected network. In particular, we consider the case that the communicated local decision variables among nodes are quantized in order to alleviate the communication bottleneck in distributed optimization. We propose the Quantized Decentralized Gradient Descent (QDGD) algorithm, in which nodes update their local decision variables by combining the quantized information received from their neighbors with their local information. We prove that under standard strong convexity and smoothness assumptions for the objective function, QDGD achieves a vanishing mean solution error under customary conditions for quantizers. To the best of our knowledge, this is the first algorithm that achieves vanishing consensus error in the presence of quantization noise. Moreover, we provide simulation results that show tight agreement between our derived theoretical convergence rate and the numerical results.

description: We show that energy dissipation partition between a liquid and a solid controls the shape and stability of droplets sliding on viscoelastic gels. When both phases dissipate energy equally, droplet dynamics is similar to that on rigid solids. When only the solid dissipate, we observe an apparent contact angle hysteresis, of viscoelastic origin. We find excellent agreement between our data and a non-linear model of the wetting of gels of our own that also indicates the presence of significant slip. Our work opens general questions on the dynamics of curved contact lines on compliant substrates.

On the origin of Damped Lyman-alpha systems: a case for LSB galaxies?

description: We use a model of galaxy disk formation to explore the metallicities, dust content, and neutral-gas mass density of damped Lyman-$α$ (D\lya) absorbers. We find that the [Zn/H] abundance measurements of D\lya systems now available can be reproduced either by a population of low surface brightness (LSB) galaxies forming at redshifts $z > 3$, whose chemical contents evolve slowly with time and whose star formation rates are described by continuous bursts, or by high surface brightness (HSB) galaxies which form continuously over an interval of $z \sim 0.5-3$ (and no higher). Although, in reality, a mixture of galaxy types may be responsible for low-z D\lya systems, our models predict that HSB galaxies form more dust, more rapidly, than LSB galaxies, and that HSB galaxies may therefore obscure background QSOs and not give rise to D\lya lines, as suggested by other researchers. Significantly, we find that the rate at which HSB disks consume neutral gas is too fast to explain the observed evolution in the neutral gas mass density with redshift, and that the consumption of hydrogen by LSB galaxies better fits the data. This further suggests that LSB disks may dominate the D\lya population at high-redshift.

Quantum quenches in driven-dissipative quadratic fermionic systems with parity-time symmetry

description: We study the quench dynamics of noninteracting fermionic quantum many-body systems that are subjected to Markovian drive and dissipation and are described by a quadratic Liouvillian which has parity-time (PT) symmetry. In recent work, we have shown that such systems relax locally to a maximum entropy ensemble that we have dubbed the PT-symmetric generalized Gibbs ensemble (PTGGE), in analogy to the generalized Gibbs ensemble that describes the steady state of isolated integrable quantum many-body systems after a quench. Here, using driven-dissipative versions of the Su-Schrieffer-Heeger (SSH) model and the Kitaev chain as paradigmatic model systems, we corroborate and substantially expand upon our previous results. In particular, we confirm the validity of a dissipative quasiparticle picture at finite dissipation by demonstrating light cone spreading of correlations and the linear growth and saturation to the PTGGE prediction of the quasiparticle-pair contribution to the subsystem entropy in the PT-symmetric phase. Further, we introduce the concept of directional pumping phases, which is related to the non-Hermitian topology of the Liouvillian and based upon qualitatively different dynamics of the dual string order parameter and the subsystem fermion parity in the SSH model and the Kitaev chain, respectively: Depending on the postquench parameters, there can be pumping of string order and fermion parity through both ends of a subsystem corresponding to a finite segment of the one-dimensional lattice, through only one end, or there can be no pumping at all. We show that transitions between dynamical pumping phases give rise to a new and independent type of dynamical critical behavior of the rates of directional pumping, which are determined by the soft modes of the PTGGE.

The predictions based on the RDWIA approach, with a realistic description of the initial state and a phenomenological relativistic complex optical potential for the description of final state interactions, better describe the measured cross sections than GENIE-SuSAv2 and RDWIA with a purely real potential.
The Ratio of Ortho- to Para-H2 in Photodissociation Regions

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

description: We discuss the ratio of ortho- to para-H2 in photodissociation regions (PDRs). We draw attention to an apparent confusion in the literature between the ortho-to-para ratio of molecules in FUV-pumped vibrationally excited states, and the H2 ortho-to-para abundance ratio. These ratios are not the same because the process of FUV-pumping of fluorescent H2 emission in PDRs occurs via optically thick absorption lines. Thus, gas with an equilibrium ratio of ortho- to para-H2 equal to 3 will yield FUV-pumped vibrationally excited ortho-to-para ratios smaller than 3, because the ortho-H2 pumping rates are preferentially reduced by optical depth effects. Indeed, if the ortho and para pumping lines are on the ``square root'' part of the curve-of-growth, then the expected ratio of ortho and para vibrational line strengths is the square root of 3, ~ 1.7, close to the typically observed value. Thus, contrary to what has sometimes been stated in the literature, most previous measurements of the ratio of ortho- to para-H2 in vibrationally excited states are entirely consistent with a total ortho-to-para ratio of 3, the equilibrium value for temperatures greater than 200 K. We present an analysis and several detailed models which illustrate the relationship between the total ratios of ortho- to para-H2 and the vibrationally excited ortho-to-para ratios in PDRs. Recent Infrared Space Observatory (ISO) measurements of pure rotational and vibrational H2 emissions from the PDR in the star-forming region S140 provide strong observational support for our conclusions.

description: This paper presents a study of dc photocurrents in biased insulators to the third order in the electric field. We find three photocurrents which are characterized by physical divergences of the third-order free-electron polarization susceptibility. In the absence of momentum relaxation and saturation effects, these dc photocurrents grow as $t^n$ $(n=2,1,0)$ with illumination time. The photocurrents are dubbed \textit{jerk}, third-order injection, and third-order shift current, respectively, and are generalizations of the second-order injection and shift currents of the bulk photovoltaic effect. We also revisit the theory of the bulk photovoltaic effect and include Fermi surface contributions which are important in metals. Finally, we show that injection, shift, and jerk currents admit simple physical interpretations in terms of semiclassical wave packet dynamics in electric fields. Experimental signatures and extensions to higher-order susceptibilities are also discussed.

description: Non-Hermiticity has emerged as a new paradigm for controlling coupled-mode systems in ways that cannot be achieved with conventional techniques. One aspect of this control that has received considerable attention recently is the encircling of exceptional points (EPs). To date, most work has focused on systems consisting of two modes that are tuned by two control parameters and have isolated EPs. While these systems exhibit exotic features related to EP encircling, it has been shown that richer behavior occurs in systems with more than two modes. Such systems can be tuned by more than two control parameters, and contain EPs that form a knot-like structure. Control loops that encircle this structure cause the system's eigenvalues to trace out non-commutative braids. Here we consider a hybrid scenario: a three-mode system with just two control parameters. We describe the relationship between control loops and their topology in the full and two-dimensional parameter space. We demonstrate this relationship experimentally using a three-mode mechanical system in which the control parameters are provided by optomechanical interaction with a high-finesse optical cavity.

description: We propose a search for Higgs decays with as many as eight leptons in the final state. This signal can arise in a simple model with a hidden vector ($A_d$) that gets mass via a hidden scalar ($h_d$) vacuum expectation value. The 125 GeV Higgs can then decay $H\rightarrow h_d h_d \rightarrow 4A_d\rightarrow 8f$, where $f$ are Standard Model fermions. We recast current searches and show that a branching ratio of $H\rightarrow h_dh_d$ as large as 10% is allowed. We also describe a dedicated search that could place bounds on BR($H\rightarrow h_dh_d$) as low as $10^{-5}$ using only 36 fb$^{-1}$ of data, with significant improvements coming from greater integrated luminosity.

description: In this study, we have shown autonomous long-term prediction with a spintronic physical reservoir. Due to the short-term memory property of the magnetization dynamics, non-linearity arises in the reservoir states which could be used for long-term prediction tasks using simple linear regression for online training. During the prediction stage, the output is directly fed to the input of the reservoir for autonomous prediction. We employ our proposed reservoir for the modeling of the chaotic time series such as Mackey-Glass and dynamic time-series data, such as household building energy loads. Since only the last layer of a RC needs to be trained with linear regression, it is well suited for learning in real time on edge devices. Here we show that a skyrmion based magnetic tunnel junction can potentially be used as a prototypical RC but any nanomagnetic magnetic tunnel junction with nonlinear magnetization behavior can implement such a RC. By comparing our spintronic physical RC approach with energy load forecasting algorithms, such as LSTMs and RNNs, we conclude that the proposed framework presents good performance in achieving high predictions accuracy, while also requiring low memory and energy both of which are at a premium in hardware resource and power constrained edge applications. Further, the proposed approach is shown to require very small training datasets and at the same time being at least 16X energy efficient compared to the sequence to sequence LSTM for accurate household load predictions.

description: We derive and analyze a novel approach for modeling and computing the mechanical relaxation of incommensurate 2D heterostructures. Our approach parametrizes the relaxation pattern by the compact local configuration space rather than real space, thus bypassing the need for the standard supercell approximation and giving a true aperiodic atomistic configuration. Our model extends the computationally accessible regime of weakly coupled bilayers with similar orientations or lattice spacing, for example materials with a small relative twist where the widely studied large-scale moire patterns arise. Our model also makes possible the simulation of multi-layers for which no interlayer empirical atomistic potential exists, such as those composed of MoS2 layers, and more generally makes possible the simulation of the relaxation of multi-layer heterostructures for which a planar moire pattern does not exist.

Dynamically reconfigurable district metered areas (DMAs) for discolouration risk management
Creators: name: Armand, Hooman
Publisher: name: Imperial College London
Year: 2018

description: In the UK, network sectorisation (DMAs) for leakage management is the driver of network topology. Water quality deteriorating mechanisms are kinetic in nature and hydraulic-dependent. Thus, the permanent closure of valves related to the sectorisation is expected to exacerbate these mechanisms. This impact has not been extensively studied and it remains uncertain. This thesis proposes a methodology to assess this impact by using surrogate hydraulic variables derived from an in-depth literature review and analysing the spatio-temporal distribution of historical discolouration complaints. By comparing and contrasting the characteristics of cohesive layers formed in WSNs with morphological and mechanical behaviour of biofilms, the role of biofilms in discolouration is identified and indicators to achieve and evaluate enhanced cleaning are discussed. Applying the proposed methodology to a large-scale case study of an operational network, comprised of 22 DMAs with various sizes, topologies, topographies, and number of boundary valves, showed that the sectorisation results in an increase in water age and decrease in flow velocity which are indicators of water quality deterioration and increased likelihood of discolouration incidents. To address the risk of water quality deterioration posed by DMAs, this thesis proposes a novel hybrid system of operation, DMAs with dynamic boundary, to enable water quality management whilst accounting for topological restrictions of DMA-based networks and without compromising the leakage detection functionality of DMAs. Three valve-scheduling controls are explored to increase the number of self-cleaning pipes within DMAs and reduce water age around the DMA boundaries by regulating the topology of DMAs and operation of control valves. Application of these controls also offers other advantages such as increasing the resilience of supply and reducing the time to respond to incidents. Further development and optimal frequency of the controls is subject to further understanding of accumulation processes and the spatio-temporal cleaning requirements within the networks.
Low-Complexity Memoryless Linearizer for Analog-to-Digital Interfaces

description: This paper introduces a low-complexity memoryless linearizer for suppression of distortion in analog-to-digital interfaces. It is inspired by neural networks, but has a substantially lower complexity than the neural-network schemes that have appeared earlier in the literature in this context. The paper demonstrates that the proposed linearizer can outperform the conventional parallel memoryless Hammerstein linearizer even when the nonlinearities have been generated through a memoryless polynomial model. Further, a design procedure is proposed in which the linearizer parameters are obtained through matrix inversion. Thereby, the costly and time consuming numerical optimization that is traditionally used when training neural networks is eliminated. Moreover, the design and evaluation incorporate a large set of multi-tone signals covering the first Nyquist band. Simulations show signal-to-noise-and-distortion ratio (SNDR) improvements of some 25 dB for multi-tone signals that correspond to the quadrature parts of OFDM signals with QPSK modulation.

description: Is thermodynamics consistent with the quantum gravity reconciliation hypothesis [A. G. Cohen et al. Phys. Rev. Lett. 82, 4971 (1999)], which establishes holographic dark energy models? Here, we have attempted to address this issue in the affirmative by concentrating on the first law of thermodynamics.

description: Bulges, often identified with the spheroidal component of a galaxy, have a complex pedigree. Massive bulges are generally red and old, but lower mass bulges have broader dispersions in color that may be correlated with disk colors. This suggests different formation scenarios. I will review possible formation sequences for bulges, describe the various signatures that distinguish these scenarios, and discuss implications for the high redshift universe.

What Can the Accretion Induced Collapse of White Dwarfs Really Explain?

description: The accretion induced collapse (AIC) of a white dwarf into a neutron star has been invoked to explain gamma-ray bursts, Type Ia supernovae, and a number of problematic neutron star populations and specific binary systems. The ejecta from this collapse has also been claimed as a source of r-process nucleosynthesis. So far, most AIC studies have focussed on determining the event rates from binary evolution models and less attention has been directed toward understanding the collapse itself. However, the collapse of a white dwarf into a neutron star is followed by the ejection of rare neutron-rich isotopes. The observed abundance of these chemical elements may set a more reliable limit on the rate at which AICs have taken place over the history of the galaxy. In this paper, we present a thorough study of the collapse of a massive white dwarf in 1- and 2-dimensions and determine the amount and composition of the ejected material. We discuss the importance of the input physics (equation of state, neutrino transport, rotation) in determining these quantities. These simulations affirm that AICs are too baryon rich to produce gamm-ray bursts and do not eject enough nickel to explain Type Ia supernovae (with the possible exception of a small subclass of extremely low-luminosity Type Ias). Although nucleosynthesis constraints limit the number of neutron stars formed via AICs to <0.1% of the total galactic neutron star population, AICs remain a viable scenario for forming systems of neutron stars which are difficult to explain with Type II core-collapse supernovae.

Exacerbations, antibiotics and the airway microbiome in chronic lung disease
Creators: name: Brill, Simon
Publisher: name: Imperial College London

description: Abstract This thesis investigates the airway microbiome in chronic obstructive pulmonary disease (COPD). The relationship of the airway microbiome to clinical disease characteristics and prophylactic antibiotic therapy is unknown, as are the ideal methods of community recruitment into clinical trials of COPD. Direct comparative data between bacterial culture and newer molecular techniques are also lacking. We used a randomised controlledantibiotic trial of patients with COPD to investigate these areas. During recruitment to this study we hypothesised that within primary care, different sources would have particular advantages when recruiting patients to clinical studies of COPD. We proposed that in stable COPD there would be aspects of the microbiome composition that would relate clinically to disease characteristics, and that when antibiotic therapy was given for three months there would be measurable changes in the microbiome as well as in bacterial resistance and clinical disease measures. We found that pulmonary rehabilitation and patient groups represented the most efficient and cost-effective way to recruit COPD patients. Our comparison between culture and molecular methods showed concordance between the techniques, but that different aspects of the microbiome are being assessed. Analysis of the microbiome at baseline showed that in one quarter of patients the COPD microbiome is dominated by the genus Haemophilus, predominantly Haemophilus influenzae, with greater levels of airway inflammation. Therapy with three months of moxifloxacin, but not azithromycin or doxycycline, was effective against placebo in reducing the burden of Haemophilus species with a concurrent reduction in inflammation. Antimicrobial resistance increased in all treatment groups. Our findings suggest that COPD patients whose microbiota is dominated by Haemophilus may derive particular benefit from prophylactic antibiotic therapy, although this drives antimicrobial resistance.
A New Approach to Statistics of Cosmological Gamma-Ray Bursts

description: We use a new method of analysis to determine parameters of cosmological gamma-ray bursts (GRBs), assuming that their distribution follows the star-formation history of the universe. Spectral evolution is calculated from an external shock model for fireball/blast wave evolution, and used to evaluate the measured peak flux, duration, and $νF_ν$ peak photon energy for a GRB source occuring at a given redshift and with given values of total energy, baryon-loading and environmental parameters. We then fit model distributions of GRB sources to the observed peak flux, duration and $νF_ν$ peak photon energy distributions. We find that the observed width of the $E_p$ and duration distributions can not be explained by cosmological redshift and time dilation effects. Rather, broad distributions of total blastwave energies and bulk Lorentz factors are necessary to explain the observed distributions simultaneously within the framework of our unifying GRB model. We discuss implications for source parameter distributions and determine a range of burst parameters consistent with the data.

On using symmetric polynomials for constructing root finding methods
Creators: name: Khomovsky, Dmitry I.
Publisher: name: arXiv

Subjects: subject: Numerical Analysis (math.NA)

description: We propose an approach to constructing iterative methods for finding polynomial roots simultaneously. One feature of this approach is using the fundamental theorem of symmetric polynomials. Within this framework, we reconstruct many of the existing root finding methods. The new results presented in this paper are some modifications of the Durand-Kerner method.
3D hand pose estimation: methods, datasets, and challenges
Creators: name: Yuan, Shanxin
Publisher: name: Imperial College London
Year: 2018

description: 3D hand pose estimation is an important task in the computer vision community due to its vast applications, including but not limited to, human computer interaction, virtual reality and augmented reality, sign language recognition, medical image analysis. The challenges for this task lie in high degree of freedom of a human hand, self-occlusions, different hand shapes, ambiguities among different fingers. The obstacles faced by the research communities are lack of proper methods and limitation in the current datasets. In view of this, I investigate in this thesis in three aspects: methods, datasets, and challenges. More specifically, the contributions of this thesis are: (1) Proposed a large-scale hand pose dataset, collected using a novel capture method, the dataset is known as the BigHand2.2M dataset; (2) Hosted a depth-based 3D hand pose challenge that attracted the top research groups across the world to evaluate the current best state-of-the-art methods, to investigate into the best practices, and to show some promising research directions; (3) Proposed a method for 3D hand pose estimation from RGB images with privileged information from depth data. Real datasets are limited in quantity and coverage, mainly due to the difficulty to annotate them. To deal with this issue, this thesis proposed a tracking system with six magnetic 6D sensors and inverse kinematics to automatically obtain 21-joints hand pose annotations of depth maps captured with minimal restriction on the range of motion. The automatic annotation method allows us to build the largest real dataset with higher joint annotations accuracy. To find out the current state of 3D hand pose estimation from depth and the next challenges, we hosted the Hands In the Million Challenge (HIM2017), and investigated the state-of-the-art methods on three tasks: single frame 3D pose estimation, 3D hand tracking, and hand pose estimation during object interaction. This thesis analysed the performance of different CNN structures with regard to hand shape, joint visibility, view point and articulation distributions. The advancement in hand pose estimation from RGB images lagged behind that of depth images, this thesis proposed a method for hand pose estimation from RGB images that uses both external large-scale depth image datasets and paired depth and RGB images as privileged information at training time. We show that providing depth information during training significantly improves performance of pose estimation from RGB images during testing.
LiBeB Energetics and Cosmic Ray Origin

description: Three different models have been proposed for LiBeB production by cosmic rays: the CRI model in which the cosmic rays are accelerated out of an ISM of solar composition scaled with metallicity; the CRS model in which cosmic rays with composition similar to that of the current epoch cosmic rays are accelerated out of fresh supernova ejecta; and the LECR model in which a distinct low energy component coexists with the postulated cosmic rays of the CRI model. These models are usually distinguished by their predictions concerning the evolution of the Be and B abundances. Here we emphasize the energetics which favor the CRS model. This model is also favored by observations showing that the bulk (80 to 90%) of all supernovae occur in hot, low density superbubbles, where supernova shocks can accelerate the cosmic rays from supernova ejecta enriched matter.

description: The electric dipole moment (EDM) plays a crucial role in determining the interaction strength of an atom with electric fields, making it paramount to quantum technologies based on coherent atomic control. We propose a scheme for engineering the potential in a Paul trap to realize a two-level quantum system with a giant EDM formed by the motional states of a trapped electron. We show that, under realistic experimental conditions, the EDM can significantly exceed the ones attainable with Rydberg atoms. Furthermore, we show that such artificial atomic dipoles can be efficiently initialized, readout, and coherently controlled, thereby providing a potential platform for quantum technologies such as ultrahigh-sensitivity electric-field sensing.
