description: It is currently feasible to start a continuous digital record of the entire sky sensitive to any visual magnitude brighter than 15 each night. Such a record could be created with a modest array of small telescopes, which collectively generate no more than a few Gigabytes of data daily. Alternatively, a few small telescopes could continually re-point to scan and reco rd the entire sky down to any visual magnitude brighter than 15 with a recurrence epoch of at most a few weeks, again always generating less than one Gigabyte of data each night. These estimates derive from CCD ability and budgets typical of university research projects. As a prototype, we have developed and are utilizing an inexpensive single-telescope system that obtains optical data from about 1500 square degrees. We discuss the general case of creating and storing data from a both an epochal survey, where a small number of telescopes continually scan the sky, and a continuous survey, composed of a constellation of telescopes dedicated each continually inspect a designated section of the sky. We compute specific limitations of canonical surveys in visible light, and estimate that all-sky continuous visual light surveys could be sensitive to magnitude 20 in a single night by about 2010. Possible scientific returns of continuous and epochal sky surveys include continued monitoring of most known variable stars, establishing case histories for variables of future interest, uncovering new forms of stellar variability, discovering the brightest cases of microlensing, discovering new novae and supernovae, discovering new counterparts to gamma-ray bursts, monitoring known Solar System objects, discovering new Solar System objects, and discovering objects that might strike the Earth.

description: We will show that, contrary to the behavior of the higher order Riesz transforms studied so far on the atomic Hardy space $\mathcal{H}^1(\mathbb R^n, γ)$, associated with the Ornstein-Uhlenbeck operator with respect to the $n$-dimensional Gaussian measure $γ$, the new Gaussian Riesz transforms are bounded from $\mathcal{H}^1(\mathbb R^n, γ)$ to $L^1(\mathbb R^n, γ)$, for any order and dimension $n$. We will also prove that the classical Gaussian Riesz transforms of higher order are bounded from an adequate subspace of $\mathcal{H}^1(\mathbb R^n, γ)$ into $L^1(\mathbb R^n, γ)$, extending Bruno's result (J. Fourier Anal. Appl. 25, 4 (2019), 1609--1631) for the first order case.

Cosmological Constant and Statistical Lensing of Giant Arcs

description: Using a singular isothermal sphere model for the matter distribution of foreground clusters of galaxies, we study the statistics of giant arcs in flat cosmologies with and without a cosmological constant. We find that the relative number of arcs predicted within $z=1$ in a universe with $Ω_0=0.3$ and $λ_0 \equiv Λ/(3H_0^2)=0.7$ is a factor of $\sim2$ larger than the one in the Einstein-de Sitter universe ($Ω_0=1, λ_0=0$). For a luminosity-dependent evolution model of the number density of background galaxies that accounts for the over-density of faint blue galaxies at $z_s\approx0.4$, the Einstein- de Sitter cosmological model predicts that about $5\%$ of clusters of galaxies with an X-ray luminosity $L_x > 2 \times 10^{44}$ erg s$^{-1}$ should have giant arcs with length-to-width ratio larger than 10. This is a factor of $\sim4$ lower than the observed fraction in the gravitational lensing survey of distant X-ray selected EMSS clusters of galaxies, indicating that the matter distribution of clusters of galaxies deviates significantly from simple isothermal spheres or/and the presence of a significant cosmological constant. It is profitable to further study the constraint on the cosmological constant from giant arcs using more realistic cluster models.

Motor learning induced neuroplasticity in minimally invasive surgery
Creators: name: Shetty, Kunal
Publisher: name: Imperial College London
Year: 2016

description: Technical skills in surgery have become more complex and challenging to acquire since the introduction of technological aids, particularly in the arena of Minimally Invasive Surgery. Additional challenges posed by reforms to surgical careers and increased public scrutiny, have propelled identification of methods to assess and acquire MIS technical skills. Although validated objective assessments have been developed to assess motor skills requisite for MIS, they poorly understand the development of expertise. Motor skills learning, is indirectly observable, an internal process leading to relative permanent changes in the central nervous system. Advances in functional neuroimaging permit direct interrogation of evolving patterns of brain function associated with motor learning due to the property of neuroplasticity and has been used on surgeons to identify the neural correlates for technical skills acquisition and the impact of new technology. However significant gaps exist in understanding neuroplasticity underlying learning complex bimanual MIS skills. In this thesis the available evidence on applying functional neuroimaging towards assessment and enhancing operative performance in the field of surgery has been synthesized. The purpose of this thesis was to evaluate frontal lobe neuroplasticity associated with learning a complex bimanual MIS skill using functional near-infrared spectroscopy an indirect neuroimaging technique. Laparoscopic suturing and knot-tying a technically challenging bimanual skill is selected to demonstrate learning related reorganisation of cortical behaviour within the frontal lobe by shifts in activation from the prefrontal cortex (PFC) subserving attention to primary and secondary motor centres (premotor cortex, supplementary motor area and primary motor cortex) in which motor sequences are encoded and executed. In the cross-sectional study, participants of varying expertise demonstrate frontal lobe neuroplasticity commensurate with motor learning. The longitudinal study involves tracking evolution in cortical behaviour of novices in response to receipt of eight hours distributed training over a fortnight. Despite novices achieving expert like performance and stabilisation on the technical task, this study demonstrates that novices displayed persistent PFC activity. This study establishes for complex bimanual tasks, that improvements in technical performance do not accompany a reduced reliance in attention to support performance. Finally, least-squares support vector machine is used to classify expertise based on frontal lobe functional connectivity. Findings of this thesis demonstrate the value of interrogating cortical behaviour towards assessing MIS skills development and credentialing.

description: We describe images of the center of the dense globular cluster M15 (NGC 7078) obtained with the Hubble Space Telescope Wide Field and Planetary Camera 2 (WFPC2). Data taken in the F336W, F439W, and F555W filters (approximately U, B, and V) are used to study the surface density distribution of the $\sim3\times10^4$~stars detected in a 5~arcmin$^2$ region within $r<2'$ (6.7$\,$pc) of the cluster center. The surface density of stars in M15 (after correction for the effects of incompleteness and photometric bias/scatter) is well represented by a power law in radius: $N(r)\sim{r}^{-0.82\pm0.12}$, over the radial range $0.3''$ (0.017$\,$pc) to $6''$. The observed power law is remarkably similar to what is expected if the center of the cluster harbors a massive black hole. Non-parametric estimates of the density profile show a monotonic rise with decreasing radius all the way in to $r=0.3''$, the smallest radius at which the density can be reliably measured; there is no indication that the profile flattens at smaller radii. Any flat core of radius larger than $2''$ (0.11$\,$pc) in the stellar distribution is ruled out at the $>95$\% significance level. The star count profile is consistent with that expected from core-collapse models or with the predicted distribution around a massive (few times $10^3\,M_\odot$) black hole. The close triplet of bright stars, AC~214, is within $0.5''$ ($1.5σ$) of the cluster centroid position.

description: In this paper, we propose a definition of Neron models of arbitrary Deligne 1-motives over Dedekind schemes, extending Neron models of semi-abelian varieties. The key property of our Neron models is that they satisfy a generalization of Grothendieck's duality conjecture in SGA 7 when the residue fields of the base scheme at closed points are perfect. The assumption on the residue fields is unnecessary for the class of 1-motives with semistable reduction everywhere. In general, this duality holds after inverting the residual characteristics. The definition of Neron models involves careful treatment of ramification of lattice parts and its interaction with semi-abelian parts. This work is a complement to Grothendieck's philosophy on Neron models of motives of arbitrary weights.

description: Cosmological simulations with gas dynamics suggest that the Lyman-alpha forest is produced mainly by "small scale structure" --- filaments and sheets that are the high redshift analog of today's galaxy superclusters. There is no sharp distinction between Lyman-alpha clouds and "Gunn-Peterson" absorption produced by the fluctuating IGM -- the Lyman-alpha forest {\it is} the Gunn-Peterson effect. Lyman limit and damped Lyman-alpha absorption arises in the radiatively cooled gas of forming galaxies. At $z~2-3$, most of the gas is in the photoionized, diffuse medium associated with the Lyman-alpha forest, but most of the {\it neutral} gas is in damped Lyman-alpha systems. We discuss generic evolution of cosmic gas in a hierarchical scenario of structure formation, with particular attention to the prospects for detecting 21cm emission from high redshift HI. A scaling argument based on the present-day cluster mass function suggests that objects with $M_{HI} >~ 5e11 h^{-1} \msun$ should be extremely rare at $z~3$, so detections with existing instruments will be difficult. An instrument like the proposed Square Kilometer Array could detect individual damped Lyman-alpha systems at high redshift, making it possible to map structure in the high redshift universe in much the same way that today's galaxy redshift surveys map the local large scale structure.

description: Machine learning is an ever-growing scientific field with increasing impact on our lives and has already revolutionized areas such as speech recognition, natural language processing and image classification. Machine learning is also of great interest to population genetics, especially as next-generation sequencing methods provide ever-larger genomic data sets that challenge traditional model-based estimators. In addition, new simulation software allows efficient generation of training data. While machine learning is already widely applied in population genetics, this emerging methodology also poses challenges, particularly with respect to robustness and interpretability. A promising strategy to address these challenges is to incorporate theoretical concepts and models from population genetics into machine learning methods. In this thesis, we present two approaches and demonstrate their advantages: First, by using a neural network to estimate the scaled mutation rate, we present a concept of how well-established model-based estimators can be integrated into the loss functions of supervised methods. Second, we incorporate key population genetic concepts such as the fixation index and Hardy-Weinberg equilibrium into an unsupervised hierarchical soft clustering method to infer population ancestry. These methods demonstrate that combining theoretical insights with data-driven learning not only enables processing of large data sets, capturing and exploiting underlying data dynamics, but also improves robustness and interpretability. With the ever-increasing availability of genetic data, such approaches have enormous potential to significantly deepen our understanding of genetic variability and evolution.

description: In recent observations with the Rossi X-Ray Timing Explorer we have detected two simultaneous quasi-periodic oscillation (QPO) peaks in the low mass X-ray binary and atoll source 4U 1735-44. The lower and higher frequency QPOs have frequencies varying between 632 and 729 Hz, and 982 and 1026 Hz, respectively. The fractional rms amplitudes are 3.7 to 8.1% and 5.0 to 5.8%. The frequency separation between the two QPOs changes from 341+-7 Hz to 296+-12 Hz. The inferred mass accretion rate during our observations is relatively low compared to that during the previous observations, where only a single QPO was present. There is weak evidence that the frequency of the QPOs correlates with the mass accretion rate, as observed in other binaries. Five X-ray bursts were recorded with no detectable oscillations with upper limits for the rms fraction of 4% to 13%.

description: Community/Public participation in medico-legal form bench-mark of health determinants and quality integrated services towards criminal justice support in health. Globally, over 44 million cases of unclaimed bodies or missing dead persons (UCBOMDPs) occur annually, 88% of these cases are in Sub Saharan Africa. In western Kenya and Kenya the rate of UCBOMDPs from road traffic accidents accounts 30% and 10% respectively, 80% of these UCBOMDPs are associated with limited community participation / next of kins in identification of UCBOMDPs, thus prevailing chronic prevalence of occupational health and safety hazards in public mortuaries. The study aimed to assess extent of community participation, uptake of community mortuary services and awareness on quality medico-legal concepts, training, embalming and assess how of knowledge, attitude and practices (KAP) of service providers influence the uptake of medico-legal concepts to mitigate occupational health and safety hazards and improve health. In Exploratory and cross sectional, 235 respondents were investigated through purposive and saturated sampling using structured questionnaires, focus group discussions (FGDs), observations and key informant interviews (KII) guides to collect data. Analyzed statistical inferences and contents analysis to saturation, results showed, 94% of mortuary service providers in tier 4 were primary and secondary education drop outs of males, on contract jobs with limited access to quality forensic in mortuary science, contrarily to trained females and males counterparts from tiers 5 and 6 mortuary facilities on permanent. Embalming by gravitation method significant OD (1.2, 0.44). Prevalence of male being admitted as UCBOMDPs in the community was significant with, OD (8.3, 0.12), RR (0.33), 95% CI (1.23, 1.02), significance were associated with male deliberately leaving IDs in houses for anonymity. Community participation in medico-legal concepts were sufficient than Detective police with OD (0.43, 6.0), 95% CI (2.12, 1.34). Advocacy to empower community comprehensively and holistically in medico-legal concepts remains vital.
Liquid atomisation processes in the crankcase of an IC engine: a computational and experimental study
Creators: name: Bergeles, Konstantinos
Publisher: name: Imperial College London
Year: 2017

description: The present thesis explores the mechanisms of aerodynamic breakup, jet disintegration and droplet formation inside the crankcase of an internal combustion engine. The work employs advanced experimental and computational tools, which allowed the description and detailed understanding of the flow processes driving liquid atomisation. The literature review identified numerous types of droplet-flow interactions, flow structures and mechanisms which required further investigation. These important parameters are currently ignored in most engineering design. Droplets, upon generation in the crankcase, is shown to be far from spherical, an assumption usually made in the engineering practice. The effect of droplet non-sphericity on its shape evolution and disintegration process was a primary research objective. The experimental part of the work allowed the detailed investigation of droplet-crossflow interactions and its subsequent atomisation for a range of Weber, Ohnesorge numbers and initial droplet aspect ratios. New, equivalent Weber and Ohnesorge numbers, incorporating the initial droplet non-sphericity, are proposed, which are able to classify the breakup of spherical and non-spherical droplets under the morphological classification charts in the literature. Additionally, new empirical correlations are presented for the breakup initiation time and maximum cross-stream droplet diameter. The experiments were further clarified with computational investigations as regards the breakup initiation time, droplet shape evolution and transitional droplet drag coefficient. The computational investigation studied the strength and location of the rollex, which for topological reasons must exist on the droplet – gas rear interface. A novel experimental setup of a rotating disc was manufactured to partially simulate the crankshaft. The jet disintegration modes and droplet formation processes, due to its rotation, are explored and described. Detailed investigation of the effect of the crankshaft rotational speed and liquid flow rate led to the clarification of the disintegration mechanisms and to the study of the breakup length of the liquid jet. Finally, a initiative was undertaken to link light-field imaging with liquid atomisation processes. A plenoptic camera prototype, designed and manufactured in-house, was used in a simplified droplet arrangement. Further to that, an algorithm was developed for the three dimensional reconstruction of the plenoptic images. The results indicated the high potential of the plenoptic concept to multiphase flows.

description: Circuit QED based quantum information processing relies on low noise amplification for signal readout. In the realm of microwave superconducting circuits, this amplification is often achieved via Josephson parametric amplifiers (JPA). In the past, these amplifiers exhibited low power added efficiency (PAE), which is roughly the fraction of pump power that is converted to output signal power. This is increasingly relevant because recent attempts to build high saturation power amplifiers achieve this at the cost of very low PAE, which in turn puts a high heat load on the cryostat and limits the number of these devices that a dilution refrigerator can host. Here, we numerically investigate upper bounds on PAE. We focus on a class of parametric amplifiers that consists of a capacitor shunted by a nonlinear inductive block. We first set a benchmark for this class of amplifiers by considering nonlinear blocks described by an arbitrary polynomial current-phase relation. Next, we propose two circuit implementations of the nonlinear block. Finally, we investigate chaining polynomial amplifiers. We find that while amplifiers with higher gain have a lower PAE, regardless of the gain there is considerable room to improve as compared to state of the art devices. For example, for a phase-sensitive amplifier with a power gain of 20 dB, the PAE is ~0.1% for typical JPAs, 5.9% for our simpler circuit JPAs, 34% for our more complex circuit JPAs, 48% for our arbitrary polynomial amplifiers, and at least 95% for our chained amplifiers.

description: Machine learning force fields (MLFFs) are an attractive alternative to ab-initio methods for molecular dynamics (MD) simulations. However, they can produce unstable simulations, limiting their ability to model phenomena occurring over longer timescales and compromising the quality of estimated observables. To address these challenges, we present Stability-Aware Boltzmann Estimator (StABlE) Training, a multi-modal training procedure which leverages joint supervision from reference quantum-mechanical calculations and system observables. StABlE Training iteratively runs many MD simulations in parallel to seek out unstable regions, and corrects the instabilities via supervision with a reference observable. We achieve efficient end-to-end automatic differentiation through MD simulations using our Boltzmann Estimator, a generalization of implicit differentiation techniques to a broader class of stochastic algorithms. Unlike existing techniques based on active learning, our approach requires no additional ab-initio energy and forces calculations to correct instabilities. We demonstrate our methodology across organic molecules, tetrapeptides, and condensed phase systems, using three modern MLFF architectures. StABlE-trained models achieve significant improvements in simulation stability, data efficiency, and agreement with reference observables. The stability improvements cannot be matched by reducing the simulation timestep; thus, StABlE Training effectively allows for larger timesteps. By incorporating observables into the training process alongside first-principles calculations, StABlE Training can be viewed as a general semi-empirical framework applicable across MLFF architectures and systems. This makes it a powerful tool for training stable and accurate MLFFs, particularly in the absence of large reference datasets.

description: We consider the chiral Lagrangian for charmed baryon fields with $J^P =\frac{1}{2}^+$ or $J^P =\frac{3}{2}^+$ quantum numbers. A chiral expansion framework for the baryon ground state masses is worked out to N$^3$LO as to compute their dependence on the up, down and strange quark masses for finite box QCD lattice simulations. It is formulated in terms of on-shell meson and baryon masses. The convergence of such a scheme is illustrated with physical masses as taken from the PDG. The counter terms relevant at N$^3$LO are correlated systematically by large-$N_c$ sum rules to leading and subleading order in a manner that keeps the renormalization scale invariance of the approach.

Detection of H-alpha emission from the Magellanic Stream: evidence for an extended gaseous Galactic halo

description: We have detected faint, diffuse H$αemission from several points along the Magellanic Stream, using the Rutgers Fabry--Perot Interferometer at the CTIO 1.5-m telescope. At points on the leading edges of the H I clouds MS II, MS III, and MS IV, we detect H$αemission of surface brightness $0.37 \pm 0.02$ Rayleighs, $0.21 \pm 0.04$ R, and $0.20 \pm 0.02$ R respectively, corresponding to emission measures of 1.0 to 0.5 \cmsixpc. We have observed several positions near the MS IV concentration, and find that the strongest emission is on the sharp leading-edge density gradient. There is less emission at points away from the gradient, and halfway between MS III and MS IV the H$αsurface brightness is $< 0.04$ R. We attribute the H$αemission at cloud leading edges to heating of the Stream clouds by ram pressure from ionized gas in the halo of the Galaxy. These observations suggest that ram pressure from halo gas plays a large role in stripping the Stream out of the Magellanic Clouds. They also suggest the presence of a relatively large density of gas, $n_{\rm H} \sim 10^{-4} cm^{-3}$, in the Galactic halo at $\sim 50$ kpc radius, and far above the Galactic plane, $b \sim -80°$. This implies that the Galaxy has a very large baryonic, gaseous extent, and supports models of Lyman-$αand metal-line QSO absorption lines in which the absorption systems reside in extended galactic halos.

Real time sEMG based muscle fatigue monitoring using low power integrated circuits
Creators: name: Koutsos, Ermis
Publisher: name: Imperial College London
Year: 2016

description: Electromyogram (EMG), the recording of the electrical impulses of the muscles, is a rich source of information, which can facilitate such an insight into our muscles and especially their activation and fatigue level. Muscle fatigue has been shown to be one of the most important biofeedback parameters of EMG in rehabilitation, ergonomics and training, by using measured results from the body to change the way we behave, improve our performance and achieve better compliance to rehabilitation. This thesis addresses the challenge of reliably and efficiently estimating a muscle’s fatigue state though monitoring surface EMG signals, with the use of low power integrated circuits. CMOS technology facilitates localised real-time processing to achieve complete miniaturisation, resulting in an information driven system rather that conventionally data driven system. Thus, reducing requirements on data transmission, saving power and increasing the degree of freedom for the user. Several EMG properties progressively change during muscle fatigue and can be quantified in the time and frequency domains using different processing techniques. CMOS technology allows to significantly reduce the power and size of the developed EMG processing technology. Firstly, a CMOS system is presented, capable of measuring the instantaneous Median Frequency (iMDF) of the EMG signal, which is considered the golden standard for muscle fatigue assessment. Continuing, a novel bit-stream cross-correlator design that greatly simplifies the sEMG signal without any loss of information is presented for the estimation of the EMG conduction velocity, which is associated with the physiological changes of the muscle during fatigue. Furthermore, a new metric similar to iMDF is introduced, combining the advantages of the bit-stream approach that can accurately track the spectral compression of the sEMG during fatigue with one bit representation. Lastly, a complete muscle fatigue monitoring System-on-Chip (SoC) is presented, offering complete insight into the underlying mechanisms and physiological changes during muscle fatigue through sEMG analysis while operating under both static and dynamic contractions. The proposed approach is scalable, as several muscle fatigue monitoring SoCs can operate in parallel and periodically relay key information about the muscle, thus reducing data transmission costs and bandwidth requirements. Finally, a succession of wearable EMG devices are presented, introducing the use of custom Application Specific Integrated Circuits in wearable electronics for unsupervised muscle fatigue monitoring. The wearable nodes are wireless while user ergonomics, power and weight were the primary design considerations.

Chronic pain in the United Kingdom and associated cardiovascular disease
Creators: name: Fayaz, Alan
Publisher: name: Imperial College London
Year: 2017

description: Prior to the studies presented in this thesis there was no widely accepted estimate for the prevalence of chronic pain in the United Kingdom, little understanding of the biological consequences of chronic pain (as compared to its psychological and social impact), and unresolved issues about the possible influence of chronic pain on cardiovascular outcomes. I have used meta-analysis to summarise prevalence estimates for a range of chronic pain phenotypes, demonstrating that just over 43% of the adult population experience pain with a duration of 3 months or greater. This figure is considerably higher than estimates often quoted in public and scientific forums. I have also outlined the impact of chronic pain on cardiovascular health through a systematic review of existing evidence, suggesting that chronic pain may be associated with cardiovascular disease and cardiovascular mortality. However, existing studies took an inconsistent and incomplete approach in their adjustment for potentially confounding factors, so it cannot be concluded that these associations are causal. I have therefore supplemented existing evidence with analysis of data from a large national survey of the population of England, adjusting for a comprehensive list of potentially confounding variables. My study shows that participants reporting chronic pain are 55% more likely to experience cardiac disease than those without pain, and that this risk increases systematically in-line with increasing chronic pain intensity. In summary, I have demonstrated that chronic pain affects a much greater proportion of the adult population on the United Kingdom than previously estimated. Furthermore, adults reporting chronic pain, in particular those most severely affected, may be at significantly increased risk of cardiac disease. Future studies should focus on determining whether reducing the impact of chronic pain can improve cardiac health.

description: Quantum sensors have notably advanced high-sensitivity magnetic field detection. Here, we report quantum sensors constructed from polarized spin-triplet electrons in photoexcited organic chromophores, specifically focusing on pentacene-doped para-terphenyl (${\approx}$0.1%). We demonstrate essential quantum sensing properties at room temperature: electronic optical polarization and state-dependent fluorescence contrast, by leveraging differential pumping and relaxation rates between triplet and ground states. We measure high optically detected magnetic resonance (ODMR) contrast ${\approx}16.8\%$ of the triplet states at room temperature, along with long coherence times under spin echo and CPMG sequences, $T_2{=}2.7μ$s and $T_2^{DD}{=}18.4μ$s respectively, limited only by the triplet lifetimes. The material offers several advantages for quantum sensing, including the ability to grow large ($cm$-scale) crystals at low cost, the absence of paramagnetic impurities, and the diamagnetism of electronic states used for sensing when not optically illuminated. Utilizing pentacene as a representative of a broader class of spin triplet-polarizable organic molecules, this study highlights new potential for quantum sensing in chemical systems.

description: In this paper, we demonstrate that the hybrid normal-superconducting-normal (NSN) structure has potential for a multifunctional thermal device which could serve for heat flux control and cooling of microstructures. By adopting the scattering matrix approach, we theoretically investigate thermal and electrical effects emerging in such structures due to the Cooper pair splitting (CPS) and elastic cotunneling phenomena. We show that a finite superconductor can, in principle, mediate heat flow between normal leads, and we further clarify special cases when this seems contradictory to the second law of thermodynamics. Among other things, we demonstrate that the CPS phenomenon can appear even in the simple case of a ballistic NSN structure.

description: In the context of ghost-free infinite derivative gravity, we consider the single graviton exchange between two spinless particles, a spinless particle and a photon, or between a spinless particle and a spin-1/2 particle. To this end, we compute the gravitational potential for the three aforementioned cases and derive the $\mathcal{O}(G\hbar^2)$ correction that arises at the linearised level. In the local theory, it is well-known that such a correction appears in the form of a Dirac delta function. Here, we show that this correction is smeared out for the nonlocal theory and, in contrast to the local theory, takes on non-zero values for a non-zero separation between the two particles. In the case of the single graviton exchange between a spinless particle and a spin-1/2 particle, we also compute the $\mathcal{O}(G\hbar)$ correction that arises in the non-static case within the non-relativistic approximation and show that it is finite in the nonlocal theory.

Practical challenges of learning and representation for large graphs
Creators: name: Chamberlain, Benjamin Paul
Publisher: name: Imperial College London
Year: 2018

description: An ever-increasing amount of the humanity's information is being stored in large graphs. The world wide web, digital social networks, e-commerce platforms and chat networks now contain digital traces of the majority of living humans. Many of the most valuable companies ever created are dedicated to organising, managing and extracting useful information from large digital graphs. Machine learning has been shown to be an important tool for automating this task. Discovering scalable machine learning systems, to extract useful information from graphs, is a problem of great practical significance. Interesting graphs, such as the web graph, often contain more information than can be stored on a single computer, and so working with the raw data presents considerable challenges. Graph representations are often employed that encapsulate key properties of the underlying data and enable certain tasks to be performed efficiently, at the expense of others. Representations are chosen to balance time complexity, space complexity and predictive performance on a downstream task, such as labelling vertices with attributes. We are concerned with problems of extracting and inferring information from large graphs and applying the results in deployed commercial systems. The research revolves around two large-scale machine learning projects (1) A system for searching and organising data from social media graphs (2) A system to profile customers through their interactions with products on an e-commerce platform. We use representations of graphs to allow algorithms to be run faster, cheaper and more accurately. Doing so allows us to satisfy systems constraints that could not be achieved by operating directly on the raw data. We demonstrate how careful choices of representation can be used to improve machine learning performance on several real-world tasks. We do this under challenging industrial constraints such as real-time serving, runtime costs or maintainability.
