description: Only one third of the in vitro fertilization treatments result in successful delivery following morphological viability assessment worldwide. A paper by Montskó et al. (2015) describes the identification of the alpha-1 chain of human haptoglobin as a potential marker of embryo viability. Using mass spectrometry, the concentration of the haptoglobin alpha-1 chain was determined in spent culture media samples of in vitro fertilized embryos and correlation was found with the outcome of the respective transfer. In the present study we investigated, whether the concentration of haptoglobin alpha-1 chain shows any correlation with morphological scores to clarify whether levels of the alpha-1 chain provide additional information on embryo viability unnoticed by the morphological assessment. In the study, pregnancy and live birth rates were examined in 143 transferred samples of 86 patients, retrospectively. Two sample groups were created. The control group contained embryos classified as ‘good’ or ‘fair’ based on the Istanbul Consensus Criteria System, while the double-assay group contained embryos assessed as ‘good’ or ‘fair’ by the morphological evaluation and as ‘viable’ by the haptoglobin assay. Clinical pregnancy rate was 30.2% in the control group, while 47.6% in the group scored parallel with morphological criteria and proteomic analysis (p Abbreviations: IVF: in vitro fertilization; SEC: spent embryo culture medium; HSA: human serum albumin; Hpt: haptoglobin; HptA1: haptoglobin alpha-1 chain; ICCS: Istanbul Consensus Criteria System; BMI: body mass index; ICSI: intracytoplasmic sperm injection
Force acting on a cluster of magnetic nanoparticles in a gradient field: a Langevin dynamics study

description: Magnetophoretic force acting on a rigid spherical cluster of single-domain nanoparticles in a constant-gradient weak magnetic field is investigated numerically using the Langevin dynamics simulation method. Nanoparticles are randomly and uniformly distributed within the cluster volume. They interact with each other via long-range dipole-dipole interactions. Simulations reveal that if the total amount of particles in the cluster is kept constant, the force decreases with increasing nanoparticle concentration due to the demagnetizing field arising inside the cluster. Numerically obtained force values with great accuracy can be described by the modified mean-field theory, which was previously successfully used for the description of various dipolar media. Within this theory, a new expression is derived, which relates the magnetophoretic mobility of the cluster with the concentration of nanoparticles and their dipolar coupling parameter. The expression shows that if the number of particles in the cluster is fixed, the mobility is a nonmonotonic function of the concentration. The optimal concentration values that maximize the mobility for a given amount of magnetic phase and a given dipolar coupling parameter are determined.

title: The prevention and resolution of disputes over property rights in twelfth and early thirteenth century Scotland
Creators: name: O'Sullivan, Eileen Marie
Publisher: name: University of Glasgow
Year: 2006
Subjects: subject: Alternative dispute resolution, right of property, Scotland, 12th century, 13th century.

description: The accepted view of dispute resolution during the twelfth and early thirteenth century is to either dismiss the possibility altogether due to a scarcity of documents or to look backward from the later thirteenth century and beyond, measuring the records of the twelfth century and early thirteenth against the more prolific and more detailed records of later periods. This has led to the widely accepted conclusion that either the means of resolving disputes in the earlier period were less sophisticated, less developed versions of later legal systems, or that the earlier period was in a legal dark age where the light of reason and systematic approaches to law had not yet developed. The evidence discussed here shows, however, that there were systematic approaches to both preventing disputes and resolving those that did occur. The documents are not in the format that came to be accepted in later periods, nor are they worded as later legal documents would be. But that there were legal decisions being made according to norms, customs and rules that were consistently applied is clear. Using complexity theory as a means of analysis allows us to see the patterns and the systematic approaches, not in a system wide context, but at the level of decision making, where these rules, norms and customs were applied to the facts by one or more decision makers in order to achieve a just result. This approach affirms the underlying concept of justice that drives any legal system, whether a more modern, well documented legal structure or one where the records are not so abundant.
The White Dwarf Companions of 56 Per and HR 3643

description: We have obtained low-dispersion IUE spectra of the stars 56 Persei (F4 V) and HR 3643 (F7 II), as part of a survey of late-type stars with a 1565 A flux excess in the TD-1 ultraviolet sky survey. The IUE spectrum of each star reveals the presence of a hot white dwarf companion. We fit the Ly alpha profile and ultraviolet continuum using pure hydrogen models, but the distance of the primary star is also needed to uniquely constrain the white dwarf parameters. We derive Teff = 16,420 +- 420 K, logg = 8.46 +- 0.2 for the white dwarf companion to 56 Per, using the photometric distance of 30.1 +- 2.8 pc. The implied white dwarf mass is 0.90 +- 0.12 Msun, considerably above the median mass (~0.6 Msun) of single white dwarfs. The parameters of the white dwarf in HR 3643 are not well constrained, mainly due to a large uncertainty in the distance. By assuming a reasonable range of gravity for the white dwarf (7.3 < log g < 9.0), we derive -1.4 < Mv < 0.6 for the F7 II star, and 28,970 < Teff < 35,990 K for the white dwarf. Prompted by our detection of a white dwarf companion of a luminous F star, we have examined the IUE archives to assess the upper limits on possible white dwarf companions to Cepheids. The detection of a Cepheid -- white dwarf binary would provide important insights concerning the most massive progenitors of white dwarfs. Only for the cases of Alp UMi and Beta Dor are existing IUE spectra of Cepheids sufficiently deep to rule out the presence of a white dwarf companion.

description: Traditional computer graphics rendering pipeline is designed for procedurally generating 2D quality images from 3D shapes with high performance. The non-differentiability due to discrete operations such as visibility computation makes it hard to explicitly correlate rendering parameters and the resulting image, posing a significant challenge for inverse rendering tasks. Recent work on differentiable rendering achieves differentiability either by designing surrogate gradients for non-differentiable operations or via an approximate but differentiable renderer. These methods, however, are still limited when it comes to handling occlusion, and restricted to particular rendering effects. We present RenderNet, a differentiable rendering convolutional network with a novel projection unit that can render 2D images from 3D shapes. Spatial occlusion and shading calculation are automatically encoded in the network. Our experiments show that RenderNet can successfully learn to implement different shaders, and can be used in inverse rendering tasks to estimate shape, pose, lighting and texture from a single image.

description: The shape of the brain's white matter connections is relatively unexplored in diffusion MRI tractography analysis. While it is known that tract shape varies in populations and across the human lifespan, it is unknown if the variability in dMRI tractography-derived shape may relate to the brain's functional variability across individuals. This work explores the potential of leveraging tractography fiber cluster shape measures to predict subject-specific cognitive performance. We implement machine learning models to predict individual cognitive performance scores. We study a large-scale database from the HCP-YA study. We apply an atlas-based fiber cluster parcellation to the dMRI tractography of each individual. We compute 15 shape, microstructure, and connectivity features for each fiber cluster. Using these features as input, we train a total of 210 models to predict 7 different NIH Toolbox cognitive performance assessments. We apply an explainable AI technique, SHAP, to assess the importance of each fiber cluster for prediction. Our results demonstrate that shape measures are predictive of individual cognitive performance. The studied shape measures, such as irregularity, diameter, total surface area, volume, and branch volume, are as effective for prediction as microstructure and connectivity measures. The overall best-performing feature is a shape feature, irregularity, which describes how different a cluster's shape is from an idealized cylinder. Further interpretation using SHAP values suggest that fiber clusters with features highly predictive of cognitive ability are widespread throughout the brain, including fiber clusters from the superficial association, deep association, cerebellar, striatal, and projection pathways. This study demonstrates the strong potential of shape descriptors to enhance the study of the brain's white matter and its relationship to cognitive function.

A Scalable Discrete-Time Survival Model for Neural Networks

description: There is currently great interest in applying neural networks to prediction tasks in medicine. It is important for predictive models to be able to use survival data, where each patient has a known follow-up time and event/censoring indicator. This avoids information loss when training the model and enables generation of predicted survival curves. In this paper, we describe a discrete-time survival model that is designed to be used with neural networks, which we refer to as Nnet-survival. The model is trained with the maximum likelihood method using minibatch stochastic gradient descent (SGD). The use of SGD enables rapid convergence and application to large datasets that do not fit in memory. The model is flexible, so that the baseline hazard rate and the effect of the input data on hazard probability can vary with follow-up time. It has been implemented in the Keras deep learning framework, and source code for the model and several examples is available online. We demonstrate the performance of the model on both simulated and real data and compare it to existing models Cox-nnet and Deepsurv.
Mechanism of superior B cell transformation by type 1 Epstein-Barr virus
Creators: name: Correia, Paulo
Publisher: name: Imperial College London
Year: 2017

description: The Epstein-Barr virus (EBV) is characterised by the ability to infect human B lymphocytes in vitro and to transform and immortalise them into lymphoblastoid cell lines (LCLs). EBV strains can be divided into type 1 and type 2, according to the sequence of the viral EBNA-2 protein. Type 1 strains exhibit a superior capacity to efficiently transform B cells and this was mapped to the type 1 EBNA-2 protein. Substitution of the serine residue located in the transactivation domain (TAD) of type 2 EBNA-2 by the equivalent aspartate-442 of type 1 protein was previously shown to confer a type 1-like cell growth phenotype to type 2. In the present study, a stronger ability to transactivate gene expression was demonstrated for type 1 EBNA-2 TAD in comparison to type 2 EBNA-2 and this was determined by aspartate-442. This residue is located next to the interaction site of the transcriptional repressor BS69 with EBNA-2. BS69 inhibits gene transactivation by type 1 and type 2 EBNA-2 but a higher BS69 affinity for type 2 EBNA-2 protein has been shown in this study. Selective EBNA-2 activation of target promoters is also involved in the differential induction of target genes by type 1 and type 2 EBNA-2. Biotinylated oligonucleotide pulldown assays showed that efficient type 1 EBNA-2 binding at the LMP-1 promoter is dependent on the PU.1 and octamer motifs. Greater binding of type 1 EBNA-2 at the differentially regulated promoters, in conjunction with its stronger transactivation ability, conferred by aspartate-442, may determine the higher induction of the LMP-1 and cellular genes required for cell growth proliferation and therefore result in superior B cell transformation by type 1 EBV.

description: Online code clones are code fragments that are copied from software projects or online sources to Stack Overflow as examples. Due to an absence of a checking mechanism after the code has been copied to Stack Overflow, they can become toxic code snippets, e.g., they suffer from being outdated or violating the original software license. We present a study of online code clones on Stack Overflow and their toxicity by incorporating two developer surveys and a large-scale code clone detection. A survey of 201 high-reputation Stack Overflow answerers (33% response rate) showed that 131 participants (65%) have ever been notified of outdated code and 26 of them (20%) rarely or never fix the code. 138 answerers (69%) never check for licensing conflicts between their copied code snippets and Stack Overflow's CC BY-SA 3.0. A survey of 87 Stack Overflow visitors shows that they experienced several issues from Stack Overflow answers: mismatched solutions, outdated solutions, incorrect solutions, and buggy code. 85% of them are not aware of CC BY-SA 3.0 license enforced by Stack Overflow, and 66% never check for license conflicts when reusing code snippets. Our clone detection found online clone pairs between 72,365 Java code snippets on Stack Overflow and 111 open source projects in the curated Qualitas corpus. We analysed 2,289 non-trivial online clone candidates. Our investigation revealed strong evidence that 153 clones have been copied from a Qualitas project to Stack Overflow. We found 100 of them (66%) to be outdated, of which 10 were buggy and harmful for reuse. Furthermore, we found 214 code snippets that could potentially violate the license of their original software and appear 7,112 times in 2,427 GitHub projects.

The Chinese innovation system for wind energy: structure, functions and performance
Creators: name: Hu, Rui
Publisher: name: Imperial College London
Year: 2017

description: Energy technology innovation is critical to transitioning to a sustainable energy system. The energy R&D expenditure worldwide has increased recently to combat the challenges of climate change, energy security and energy affordability. Emerging economies play an increasingly important role in energy technology innovation. As the largest energy producer and consumer, China’s energy technology innovation has an influential impact on the global energy system. China has emerged as the largest investor and user of renewable energy technology. The country accounts for 33% of the global wind power capacity, far ahead of the USA (17%) and Germany (11%). Among the world’s ten largest wind turbine producers, half of them are Chinese enterprises. China’s rapid development of wind technology attracted wide interest. The two key questions are a) how does China compare with leading countries in wind technology innovation, and b) what factors have been responsible for China’s successes and failures. This thesis draws upon innovation systems theory and innovation metrics to answer these two questions. It is found that China has caught up fast in inputs and certain outputs but significantly lags the leading countries in other aspects especially outcomes. The relative weakness in invention capability represents China’s most obvious bottlenecks. It demonstrates that the country’s system performance is highly related to the fulfilment of the system functions which are affected by the presence and capability of the structural elements. The thesis is offered as a comprehensive study on China’s wind energy innovation system. It presents useful lessons on facilitating the generation, adoption and diffusion of renewable energy technology as well as the challenges that need to be addressed to smooth the energy transition globally. The research makes methodological, empirical and theoretical contributions to the innovation systems literature.
CIV Absorption From Galaxies in the Process of Formation

description: We investigate the heavy element QSO absorption systems caused by gas condensations at high redshift which evolve into galaxies with circular velocity of 100 to 200 km/s at the present epoch. Artificial QSO spectra were generated for a variety of lines-of-sight through regions of the universe simulated with a hydrodynamics code. The CIV and HI absorption features in these spectra closely resemble observed CIV and HI absorption systems over a wide range in column density. CIV absorption complexes with multiple-component structure and velocity spreads up to about 600 km/s are found. The broadest systems are caused by lines-of-sight passing through groups of protogalactic clumps with individual velocity dispersions of less than 150 km/s aligned along filamentary structures. The temperature of most of the gas does not take the photoionization equilibrium value. This invalidates density and size estimates derived from thermal equilibrium models. Consequences for metal abundance determinations are briefly discussed. We predict occasional exceptionally large ratios of CIV to HI column density (up to a third) for lines-of-sight passing through compact halos of hot gas with temperature close to 3 10^5 K. Our model may be able to explain both high-ionization multi-component heavy-element absorbers and damped Lyman alpha systems as groups of small protogalactic clumps.

description: We present a large sample of high-precision, coherently-dedispersed polarization profiles of millisecond pulsars (MSPs) at frequencies between 410 and 1414 MHz. These data include the first polarimetric observations of several of the pulsars, and the first low-frequency polarization profiles for others. Our observations support previous suggestions that the pulse shapes and polarimetry of MSPs are more complex than those of their slower relatives. An immediate conclusion is that polarimetry-based classification schemes proposed for young pulsars are of only limited use when applied to millisecond pulsars.

The lung microbiome in virus-induced asthma exacerbations
Creators: name: Wong, Ernie Hoi Cheung
Publisher: name: Imperial College London
Year: 2017

description: Acute asthma exacerbations cause significant morbidity and healthcare burden. Up to 60% of acute exacerbations are associated respiratory viruses, particularly human rhinoviruses. The role of bacteria in acute exacerbations is unclear yet antibiotics are frequently prescribed. Recent studies revealed a greater abundance of potentially pathogenic bacteria (e.g. Haemophilus spp.) within the airway microbiota in asthma, whilst a greater abundance of commensals (e.g. Prevotella spp.) were observed in health. The current project examined the dynamics of the airway microbiota in the context of a virus-induced asthma exacerbation. The airway microbiota was assessed in a cohort of mild/ moderate asthmatic subjects. Sputum samples were obtained at baseline and following naturally-occurring cold and underwent 16S rRNA gene sequencing. During acute cold, increased relative abundance of Neisseria sp. (Neisseria_2974) significantly correlated with greater peak flow (PEF) decline and IL-1b level. In contrast, Prevotella and Veillonella sp. (Veillonella_10839) relative abundances correlated with reduced PEF decline and lower IL-1b and IL-8 levels respectively. To validate these findings and evaluate the impact of human rhinovirus on the airway microbiota, a cohort of moderate asthmatic and healthy subjects were experimentally infected with rhinovirus-16. Bronchoalveolar lavage was obtained at baseline and at two time-points post infection. The microbiota community between asthmatic and healthy subjects did not differ significantly at baseline or post rhinovirus-16 infection. Following rhinovirus-16 infection, increased Neisseria_2074 relative abundance again correlated with greater PEF decline whilst increased Prevotella relative abundance correlated with reduced clinical symptoms. Furthermore, rhinovirus-16 viral load exhibited a significant linear relationship with the extent of microbiota community change, suggesting that severity of rhinovirus-16 infection may directly impact on the microbiota. In conclusion, an imbalanced airway microbiota was associated with greater PEF decline and pro-inflammatory cytokine levels during a virus-induced asthma exacerbation, though the precise role of the microbiota remains to be determined.

description: We follow the evolution of 3He in stars of mass 0.8 -- 10 M (solar units) for Pop. I and II compositions from the main sequence until advanced stages on the AGB. Under standard assumptions we confirm earlier results of more restricted investigations that low-mass stars up to 5 M are net producers of 3He. We show that the inclusion of additional mixing due to diffusion beneath the convective envelope simultaneously leads to observed carbon isotope anomalies observed in globular cluster Red Giants and to a strong reduction of 3He, such that stars exhibiting such anomalies will have destroyed 3He contrary to the standard picture.

On the Radio-to-X-ray light curves of SN 1998bw and GRB 980425
Creators: name: Iwamoto, K.
Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)

description: We calculate radio-to-X-ray light curves for afterglows caused by non-thermal emission from a highly relativistic blast wave, which is inferred from the gamma-ray flux detected in GRB 980425 and from the very bright radio emission detected in SN 1998bw. We find that the observed gamma-ray and radio light curves are roughly reproduced by the synchrotron emission from a relativistic fireball. The optical flux predicted for the non-thermal emission is well below that of the thermal emission observed for SN 1998bw so that it will not be seen at least for a few years. The model predicts the X-ray flux just above the detection limit of BeppoSAX for the epoch when it was pointed to the field of GRB980425. Therefore, the nondetection of X-ray and optical afterglows is consistent with the model. The models presented here are consistent with the physical association between SN 1998bw and GRB980425, and lend further support to the idea that this object might correspond to an event similar to the ``hypernova'' or ``collapsar'' -- events in which the collapse of a massive star forms a rotating black hole surrounded by a disk of the remnant stellar mantle.

Analytic Relations between the Observed Gravitational Microlensing Parameters With and Without the Effect of Blending
Creators: name: Han, Cheongho
Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: When a microlensing light curve is contaminated by blended light from unresolved stars near the line of sight to the lensed star, the light curve shape and corresponding parameterization for the event will differ from the values expected when the event is not affected by blending. As a result, blending makes it difficult to identify the major lens population and to estimate the amount of lensing matter. In order to estimate the effect of blending on the result of lensing experiments, it is, therefore, essential to know how the observed lensing parameters change depending on the fraction of blended light. Previously, the changed lensing parameters were obtained with a statistical method that not only required a large amount of computation time but also was prone to uncertainty. In this paper, we derive analytic relations between the lensing parameters with and without the effect of blending. By using these relations, we investigate the dependence of the observed lensing parameters on the amount of blended light, the impact parameter, and the threshold amplification for event detection.

From spline wavelet to sampling theory on circulant graphs and beyond– conceiving sparsity in graph signal processing
Creators: name: Kotzagiannidis, Madeleine S.
Publisher: name: Imperial College London
Year: 2017

description: Graph Signal Processing (GSP), as the field concerned with the extension of classical signal processing concepts to the graph domain, is still at the beginning on the path toward providing a generalized theory of signal processing. As such, this thesis aspires to conceive the theory of sparse representations on graphs by traversing the cornerstones of wavelet and sampling theory on graphs. Beginning with the novel topic of graph spline wavelet theory, we introduce families of spline and e-spline wavelets, and associated filterbanks on circulant graphs, which lever- age an inherent vanishing moment property of circulant graph Laplacian matrices (and their parameterized generalizations), for the reproduction and annihilation of (exponen- tial) polynomial signals. Further, these families are shown to provide a stepping stone to generalized graph wavelet designs with adaptive (annihilation) properties. Circulant graphs, which serve as building blocks, facilitate intuitively equivalent signal processing concepts and operations, such that insights can be leveraged for and extended to more complex scenarios, including arbitrary undirected graphs, time-varying graphs, as well as associated signals with space- and time-variant properties, all the while retaining the focus on inducing sparse representations. Further, we shift from sparsity-inducing to sparsity-leveraging theory and present a novel sampling and graph coarsening framework for (wavelet-)sparse graph signals, inspired by Finite Rate of Innovation (FRI) theory and directly building upon (graph) spline wavelet theory. At its core, the introduced Graph-FRI-framework states that any K-sparse signal residing on the vertices of a circulant graph can be sampled and perfectly reconstructed from its dimensionality-reduced graph spectral representation of minimum size 2K, while the structure of an associated coarsened graph is simultaneously inferred. Extensions to arbitrary graphs can be enforced via suitable approximation schemes. Eventually, gained insights are unified in a graph-based image approximation framework which further leverages graph partitioning and re-labelling techniques for a maximally sparse graph wavelet representation.
A step towards estimation of the neutral-hadron size: the gravitational mass radius of pi0 meson in a relativistic theory of composite particles

description: We extend our nonperturbative essentially relativistic approach, elaborated previously, to perform an approximate estimation of the size of pi0 meson. We present detailed argumentation for choosing the mass mean square radius (MSR) for this purpose. Its value calculated in our approach, using three model quark-antiquark wave functions in pion, is (0.5-0.53) fm. The neutral-pion electromagnetic form factor is zero in accordance with the charge-conjugation symmetry. We demonstrate ambiguities encountered when using standard definitions of mechanical MSR for the size. We discuss MSRs obtained in various approaches and their comparison with each other and with our results.

The use of online rapid sampling microdialysis in the clinical detection of tissue ischaemia
Creators: name: Damji, Samir
Publisher: name: Imperial College London
Year: 2016

description: Tissue ischaemia has a varied aetiology and presentation, with the potential to affect multiple organ systems and lead to significant morbidity and mortality. The detection of clinical ischaemia with microdialysis sampling forms the primary focus of this work. Microdialysis (MD) allows the extracellular composition of tissue to be characterised in vivo and is incorporated into a new class of analyser. Rapid sampling on-line microdialysis (rsMD), analyses the dialysis liquid stream from a patient on-line, at high time resolution. The device has been validated in ex-vivo bench work and animal studies, however I aimed to utilise this technology to create a tool that reliably detects tissue ischaemia in the following clinical settings: 1. Detection of colonic ischaemia following abdominal aortic aneurysm (AAA) repair 2. Detection of an anastomotic leak following formation of a gastrointestinal (GI) anastomosis 3. Renal transplant allograft viability assessment in the preservation period In a prospective observational study of 10 patients undergoing AAA repair, a MD catheter was tunnelled into the mesentery of the sigmoid colon. Each patient underwent monitoring for incremental changes in the concentration of the metabolic markers of ischaemia. I identified transient subclinical ischaemic events that have not been previously described and demonstrated that MD may act as an effective tool in the early diagnosis of colonic ischaemia. In my second study, I aimed to assess the feasibility of using rsMD in the early detection of anastomotic leaks following formation of a GI anastomosis. I developed an ex-vivo MD protocol for intraperitoneal lactate measurement and sampled drain fluid from 20 patients having undergone GI surgery. In a confirmed anastomotic leak, I identified a rise in intraperitoneal lactate concentrations 3 days prior to the development of symptoms and 7 days prior to the confirmation of the diagnosis. In my final study, I aimed to assess the feasibility of utilising rsMD for organ viability assessment in a DCD porcine model. 7 un-perfused and 8 perfused kidneys were monitored at room temperature in the control group with 5 kidneys monitored in the preservation group. These kidneys underwent SCS after retrieval, followed by tissue monitoring. This preliminary study provided a baseline ischaemic profile for porcine kidneys whilst validating the technique, allowing appropriate comparison when examining the effect of organ preservation via SCS or HMP. 14 porcine kidneys were subjected to 15 minutes warm ischaemia, then placed upon models of SCS or HMP. I demonstrated that HMP appears superior to SCS at attenuating injury accumulated during warm ischaemia and that rsMD is feasible for the assessment of lactate concentration during organ preservation.
Precise predictions for the QCD axion contribution to dark radiation with full phase-space evolution

description: We compute the QCD axion contribution to the energy density of dark radiation, parameterized by $ΔN_{\rm eff}$, by solving Boltzmann equations for the momentum distribution functions including the effects of quantum statistics for all particles involved in the axion production processes. This approach gives precise prediction for $ΔN_{\rm eff}$ independently on whether axions are produced via freeze-out or freeze-in. We focus on axions produced via flavor-conserving and flavor-violating interactions with leptons. Our precise predictions for $ΔN_{\rm eff}$ can differ from those assuming thermal shape for the momentum distribution functions, as commonly done in the literature, by more than the experimental precision of future Cosmic Microwave Background (CMB) observations. Current lower limits on the axion couplings from Planck constraints on $ΔN_{\rm eff}$ are also affected by our precise computation which, in particular, results in a strongly relaxed bound on flavor-violating axion couplings to tau lepton and muon or electron.

Robustness and resilience analysis of urban road networks
Creators: name: Shang, Wenlong
Publisher: name: Imperial College London
Year: 2016

description: This thesis investigates the robustness and resilience of urban road networks (URNs) in the presence of either local or global disruptions. The problem is approached from the two perspectives of complex network theory and traffic network modelling. The former mainly considers the topological characteristics of the networks, while the latter explores the flow characteristics, demand distribution, user behaviour, control mechanisms, and their combined effect on the network’s performance under disruption. Building on complex network theory, the thesis conducts a topological analysis of URNs using topological indices such as clustering coefficient (CC) and weighted betweenness centrality (WBC). The relationships among indegree, outdegree, WBC and CC are also examined. Following this, the small-world property and community detections for URNs are conducted. The topological indices are then examined in detail in conjunction with operational indices that take into account link capacity, travel demand and driver behaviour. The potential correlations between these various indices are investigated based on their importance for the nodes/links in the network. The thesis also proposes a new relative area index (RAI) quantitatively to analyse the robustness of URNs afflicted by global capacity disruptions, and this index may shed light on the planning and management of URNs. In the second approach, the thesis employs day-to-day evolutionary dynamics to capture the transient state of URNs in the event of disruption. Both agent-based and continuum modelling approaches are considered for the network simulation, employing novel concepts such as percolation theory to quantify the network performance. Different network control measures, such as variable message signs (VMS) and adaptive signal control are incorporated into the day-to-day models in order to mitigate the congestion and delays caused by unexpected disruptions. Two key performance indicators (KPI), rapidity, and the new relative area index (RAI), are derived to represent and quantify the resilience and robustness respectively. Extensive simulation studies are conducted to assess the performance of networks equipped with various control mechanisms and under different levels of degradation.
