Heterotic String Conformal Field Theory And A-D-E Singularities
Creators: name: Witten, Edward
Publisher: name: arXiv
Year: 1999
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We analyze the behavior of the heterotic string near an A-D-E singularity without small instantons. This problem is governed by a strongly coupled worldsheet conformal field theory, which, by a combination of O(alpha') corrections and worldsheet instantons, smooths out the singularities present in the classical geometry.

Metric collapsing on calabi-yau 3-folds
Creators: name: Li, Yang
Publisher: name: Imperial College London
Year: 2019

description: The aim of this thesis is to describe the collapsing Calabi-Yau (CY) metrics on a CY 3-fold with a Lefschetz K3 fibration, from both the a priori estimate perspective and the gluing perspective. Collapsing CY metric is a well studied subject, but most of the previous works concentrate on the behaviour away from the singular fibres, and the full description of the metric was only available in a very small number of cases, mostly relying on very favourable gluing ansatz. From the nonlinear perspective, the essential realisation is that by restricting the type of singularities, and under some conjecture in pluripotential theory, then a small neighbourhood of the singular fibre has a local noncollapsing bound, which enables us to understand the pointed Gromov-Hausdor limit of the singular fibre in the scale where the fibre volume is 1. This gives strong heuristic evidence that there is a much finer scale near the nodal points in the fibration, where the scaled limit is a CY metric on C3 with maximal volume growth and singular tangent cone at infinity. This model CY metric is rigorously constructed using a noncompact version of Yau's solution to the Calabi conjecture. The model metric enables a gluing description of the collapsing CY metrics. The diffi culty of the gluing lies in the coarse nature of the gluing ansatz, and the fact that the metric has many types of characteristic behaviours at different scales. We overcome this by developing a sharp linear theory, using some earlier ideas of Gabor Sz eklyhidi.

Searches for invisibly decaying Higgs bosons produced through vector boson fusion at 13 TeV and cloud computing for high energy physics with the Compact Muon Solenoid experiment
Creators: name: Di Maria, Riccardo
Publisher: name: Imperial College London
Year: 2019

description: Searches for invisible decays of the Higgs boson, produced via vector boson fusion, are presented in this thesis. Data from proton-proton collisions at \sqrts, collected with the CMS detector during 2016 and corresponding to an integrated luminosity of ${\SI{35.9}{fb^{-1}}}$, are used. The data are in agreement with the standard model prediction, and the observed (expected) upper limits on the invisibly decaying Higgs boson branching ratio \brhinv are $0.58(0.30)$ and $0.33(0.25)$ at $95\%$ CL for the `cut-based' and `shape-based' approaches, respectively, as published in \ReferenceRef{Sirunyan:2018owy}. Several combinations with other relevant analyses are performed using data from Run-1, Run-2 (2015), and 2016 to further improve the sensitivity to \brhinv, and the results are published in Refs.\xspace\cite{Sirunyan:2018owy,Khachatryan:2016whc}. The observed (expected) upper limit on \brhinv is set at $0.19(0.15)$ at $95\%$ CL from the combination performed with all datasets, and it is the most stringent limit to date. Interpretations of the result under non-SM production assumptions and Higgs-portal models are also provided. The observed (expected) $95\%$ CL upper limit on $\frac{\sigma}{\sigma_\text{SM}}\times\brhinv$ varies in the range $[0.14,0.24]([0.11,0.19])$, assuming non-SM production cross-sections. The observed $90\%$ CL upper limit of $\brhinv < 0.16$ is translated into an upper limit on the spin-independent DM-nucleon elastic scattering cross-section. This limit is the most stringent constraint for $m_{\chi}
New S-dualities in N=2 supersymmetric SU(2) x SU(2) gauge theory

description: New S-dualities in a scale invariant N=2 gauge theory with SU(2) x SU(2) gauge group are derived from embeddings of the theory in two different larger asymptotically free theories. The true coupling space of the scale invariant theory is a 20-fold identification of the coupling space found in the M- and string-theory derivations of the low energy effective action, implying a larger S-duality group. Also, this coupling space is different from the naively expected direct product of two SL(2,Z) fundamental domains, as it contains a different topology of fixed points.

description: The elliptic flow of inclusive and direct photons was measured at mid-rapidity in two centrality classes 0-20% and 20-40% in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV by ALICE. Photons were detected with the highly segmented electromagnetic calorimeter PHOS and via conversions in the detector material with the $e^{+}e^{-}$ pairs reconstructed in the central tracking system. The results of the two methods were combined and the direct photon elliptic flow was extracted in the transverse momentum range $0.9 < p_{\rm T} < 6.2$ GeV/$c$. A comparison to RHIC data shows a similar magnitude of the measured direct-photon elliptic flow. Hydrodynamic and transport model calculations are systematically lower than the data, but are found to be compatible.

description: Background and aims: During the last decades, substantial progress has been made in both medical and surgical treatment of inflammatory bowel disease (IBD). The aim of this study was to determine the use of anti-TNFs and surgery during the first 3 years after diagnosis in IBD patients across the four health regions in Norway using nationwide patient registry data. Methods: This study used nationwide data from the Norwegian Patient Registry. Cumulative incidence of anti-TNF exposure and major surgery was calculated for patients diagnosed in 2010–2012. The analyses were stratified by diagnosis and health region. All patients were followed for an equal period of 3 years from diagnosis. Results: The study population included 8,257 IBD patients first registered between 2010 and 2012, of whom 2,829 were diagnosed with Crohn’s disease (CD) and 5,428 with ulcerative colitis (UC). Across Norway’s health regions, the cumulative incidence of major surgery after 3 years varied from 11.4% to 17.1% for CD and from 4.6% to 6.9% for UC. The cumulative incidence of anti-TNF exposure varied from 20.9% to 31.4% for CD and from 8.0% to 13.5% for UC. The region with the lowest anti-TNF use had the highest surgery rates for both UC and CD. Conclusions: Cumulative incidence of anti-TNF exposure and surgery varied significantly across Norway’s health regions during the three first years after IBD diagnosis.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: Supergravity on $AdS_3\times S^3\times {\bf T}^4$ has a dual description as a conformal sigma-model with the target space being the moduli space of instantons on the noncommutative torus. We derive the precise relation between the parameters of this noncommutative torus and the parameters of the near-horizon geometry. We show that the low energy dynamics of the system of $D1D5$ branes wrapped on the torus of finite size is described in terms of the noncommutative geometry. As a byproduct, we give a prediction on the dependence of the moduli space of instantons on the noncommutative ${\bf T}^4$ on the metric and the noncommutativity parameter. We give a compelling evidence that the moduli space of stringy instantons on ${\bf R}^4$ with the $B$ field does not receive $α'$-corrections. We also study the relation between the $D1D5$ sigma-model instantons and the supergravity instantons.

Dysregulated endogenous opioid signalling and reward processing in alcohol dependence
Creators: name: Turton, Samuel Patrick
Publisher: name: Imperial College London
Year: 2018

description: Alcohol dependence has been estimated to affect 5.5.% of adults in Europe and has a significant impact on an individual’s physical and mental health and also substantial costs to wider society. Current treatments for alcohol dependence, such as psychosocial interventions and pharmacotherapy, have limited success. Most individuals relapse to alcohol use within a year and this reflects a substantial unmet need. Addiction has been described as a ‘reward deficient’ state and there is evidence that the endogenous opioid system, which plays an important role in reward, is dysregulated in alcohol dependence and other addictions. This thesis aimed to characterise the endogenous opioid system in abstinent alcohol dependent participants using [11C]carfentanil, a selective mu-opioid receptor (MOR) agonist positron emission tomography (PET) radioligand, and an oral 0.5mg/kg dexamphetamine challenge to examine MOR availability and endogenous opioid release. Furthermore, the associations between reward responses, measured as financial reward anticipation during a monetary incentive delay (MID) task functional magnetic resonance imaging (fMRI) paradigm, MOR availability and endogenous opioid release in healthy controls, alcohol dependent and gambling disorder participants were also examined and compared. Abstinent alcohol dependent participants did not show any differences in MOR availability compared with healthy controls, but there was evidence of blunted dexamphetamine- induced endogenous opioid release. There were associations between MID task financial reward anticipation responses and MOR availability and dexamphetamine-induced endogenous opioid release in both alcohol dependent and gambling disorder participants. The results suggest that low endogenous opioid tone may be an important factor in alcohol dependence and other addictions. There is also evidence of a link between dysregulated endogenous opioid signalling and dysregulated reward responses in addiction. Further research is required to understand how dysregulated endogenous opioid signalling is associated with relapse risk, and which treatments might be most effective in mediating dysregulated endogenous opioid signalling and reward sensitivity.
Medical image synthesis in the diagnosis and study of neurodegenerative diseases
Creators: name: Bowles, Christopher
Publisher: name: Imperial College London
Year: 2018

description: Medical imaging is a cornerstone of modern healthcare. The ability to acquire images from inside a patient has revolutionised the way doctors diagnose and treat diseases, with almost all clinical pipelines now involving imaging to some degree. The development of these imaging methods has led to the field of medical image computing, where a multitude of tools and techniques have been proposed to aid clinicians and researchers in interpreting and analysing these images. One such family of techniques involves generating synthetic medical images. Image synthesis techniques are wide and varied, ranging from basic phantoms, to disease atlases, to high resolution photo-realistic subject-specific images. Their applications are similarly diverse: for developing novel acquisition protocols, training and testing algorithms, visualising changes in disease, predicting particular image types from others, and improving image quality and resolution. This thesis examines the use of medical image synthesis with a particular focus on applications in neurodegenerative diseases. A method for synthesising subject-specific non-pathological images from pathological images is first proposed and used for the unsupervised brain lesion segmentation. We next show how generative adversarial networks (GANs) can be used to both analyse the structural changes seen in patients with Alzheimer's disease, and to add or remove these changes from patient images to produce a subject-specific prediction of disease progression. Finally we investigate how GAN-derived synthetic data can be used to increase the size of training datasets, and under what conditions this additional data can lead to an improvement across a variety of segmentation tasks. Within this context we explore two situations: where only a small amount of labelled data is available, and where a large amount of unlabelled data is also available. We show that the proposed methods can lead to significant improvements in segmentation results, especially when a small amount of labelled data is available.

description: Narrow-line Seyfert 1 (NLS1) galaxies are a peculiar subclass of active galactic nuclei (AGN). Among them, TXS 1206+549 belongs to a small group of radio-loud and gamma-ray-emitting NLS1 galaxies. We focus on the radio properties of this galaxy by analysing archival, high-resolution, very long baseline interferometry (VLBI) imaging observations taken at 8 GHz frequency in six epochs between 1994 and 2018. Using the milliarcsecond-scale radio structure, we can resolve a core and a jet component whose angular separation increases by (0.055 +/- 0.006) mas/yr. This corresponds to an apparent superluminal jet component motion of (3.5 +/- 0.4) c. From the core brightness temperature and the jet component proper motion, we determine the characteristic Doppler-boosting factor, the bulk Lorentz factor, and the jet viewing angle. We find no compelling evidence for a very closely aligned blazar-type jet. The parameters for TXS 1206+549 resemble those of radio-loud quasar jets with a moderate Lorentz factor (Gamma~4) and theta~24 deg inclination to the line of sight.

description: By performing the canonical quantization of the Abelian Chern-Simons model on the light-front (as suggested by Dirac), we clarify some controversies appearing in recent papers that discuss the relation between the existence of excitations carrying fractional spin and statistics (anyons) and this model. Properties of the Chern-Simons model on the light-front are investigated in detail, following the Dirac method for constrained dynamical systems, both for a coupled complex scalar field as well as for a spinor field.

description: The prominent radio quasar PKS 2215+020 (J2217+0220) was once labelled as a new laboratory for core--jet physics at redshift z=3.572 because of its exceptionally extended jet structure traceable with very long baseline interferometric (VLBI) observations up to a ~600 pc projected distance from the compact core and a hint of an arcsec-scale radio and an X-ray jet. While the presence of an X-ray jet could not be confirmed later, this active galactic nucleus is still unique at high redshift with its long VLBI jet. Here, we analyse archival multi-epoch VLBI imaging data at five frequency bands from 1.7 to 15.4 GHz covering a period of more than 25 years from 1995 to 2020. We constrain apparent proper motions of jet components in PKS 2215+020 for the first time. Brightness distribution modeling at 8 GHz reveals a nearly 0.02 mas/yr proper motion (moderately superluminal with apparently two times the speed of light), and provides delta=11.5 for the Doppler-boosting factor in the inner relativistic jet that is inclined within 2 deg to the line of sight and has a Gamma=6 bulk Lorentz factor. These values qualify PKS 2215+020 as a blazar, with rather typical jet properties in a small sample of only about 20 objects at z>3.5 that have similar measurements to date. According to the 2-GHz VLBI data, the diffuse and extended outer emission feature at ~60 mas from the core, probably a place where the jet interacts with and decelerated by the ambient galactic medium, is consistent with being stationary, albeit slow motion cannot be excluded based on the presently available data.

description: A perturbation theory for Massive Thirring Model (MTM) in radial quantization approach is developed. Investigation of the twisted sector in this theory allows us to calculate the vacuum expectation values of exponential fields $ exp iaphi (0) $ of the sine-Gordon theory in first order over Massive Thirring Models coupling constant. It appears that the apparent difficulty in radial quantization of massive theories, namely the explicite ''time'' dependence of the Hamiltonian, may be successfully overcome. The result we have obtained agrees with the exact formula conjectured by Lukyanov and Zamolodchikov and coincides with the analogous calculations recently carried out in dual angular quantization approach by one of the authors.

description: The Australian lungfish, Neoceratodus forsteri (Krefft 1870), is the sole extant member of the Ceratodontidae within the Dipnoi, a small order of sarcopterygian (lobe-finned) fishes, that is thought to be the earliest branching species of extant lungfishes, having changed little over the last 100 million years. To extend studies on anatomical adaptations associated with the fish–tetrapod transition, the ultrastructure of the cornea and iris is investigated using light and electron (transmission and scanning) microscopy to investigate structure–function relationships and compare these to other vertebrate corneas (other fishes and tetrapods). In contrast to previous studies, the cornea is found to have only three main components, comprising an epithelium with its basement membrane, a stroma with a Bowman's layer and an endothelium, and is not split into a dermal (secondary) spectacle and a scleral cornea. The epithelial cells are large, relatively low in density and similar to many species of non-aquatic tetrapods and uniquely possess numerous surface canals that contain and release mucous granules onto the corneal surface to avoid desiccation. A Bowman's layer is present and, in association with extensive branching and anastomosing of the collagen fibrils, may be an adaptation for the inhibition of swelling and/or splitting of the stroma during its amphibious lifestyle. The dorsal region of the stroma possesses aggregations of pigment granules that act as a yellow, short wavelength-absorbing filter during bright light conditions. Desçemet's membrane is absent and replaced by an incomplete basement membrane overlying a monocellular endothelium. The iris is pigmented, well-developed, vascularised and contractile containing reflective crystals anteriorly. Based upon its ultrastructure and functional adaptations, the cornea of N. forsteri is more similar to amphibians than to other bony fishes and is well-adapted for an amphibious lifestyle.

description: Tree crown attributes are important parameters during the assessment and monitoring of forest ecosystems. Canopy height models (CHMs) derived from airborne laser scanning (ALS) data have proved to be a reliable source for extracting different biophysical characteristics of single trees and at stand level. However, ALS-derived tree measurements (e.g., mean crown diameter) can be negatively affected by pits that appear in the CHMs. Thus, we propose a novel method for generating pit-free CHMs from ALS point clouds for estimating crown attributes (i.e., area and mean diameter) at the species level. The method automatically calculates a threshold for a pixel based on the range of height values within neighbouring pixels; if the pixel falls below the threshold then it is recognized as a pitted pixel. The pit is then filled with the median of the values of the neighbouring pixels. Manually delineated individual tree crowns (ITC) of four deciduous and two coniferous species on Colour Infrared (CIR) stereo images were used as a reference in the analysis. In addition, a variety of different algorithms for constructing CHMs were compared to investigate the performance of different CHMs in similar forest conditions. Comparisons between the estimated and observed crown area (R2 = 0.95, RMSE% = 19.12% for all individuals) and mean diameter (R2 = 0.92, RMSE% = 12.16% for all individuals) revealed that ITC attributes were correctly estimated by segmentation of the pit-free CHM proposed in this study. The goodness of matching and geometry revealed that the delineated crowns correctly matched up to the reference data and had identical geometry in approximately 70% of cases. The results showed that the proposed method produced a CHM that estimates crown attributes more accurately than the other investigated CHMs. Furthermore, the findings suggest that the proposed algorithm used to fill pits with the median of height observed in surrounding pixels significantly improve the accuracy of the results the species level due to a higher correlation between the estimated and observed crown attributes. Based on these results, we concluded that the proposed pit filling method is capable of providing an automatic and objective solution for constructing pit-free CHMs for assessing individual crown attributes of mixed forest stands.

description: A model of SU(2) gauge theory in the space-time $R\times S^3$ is constructed in terms of local gauge-invariant variables. A metric tensor $g_{μν}$ is defined starting with the components of the strength tensor $F_{μν}^k$ and of its dual $\widetilde{F}_{μν}^k$. It is shown that the components $g_{μν}$ determine the gauge field equations if some supplementary constraints are imposed. Two families of analitical solutions of the field equations are also obtained.

Solving the Hierarchy Problem with Noncompact Extra Dimensions
Creators: name: Cohen, Andrew G.

description: We show that gravitational effects of global cosmic 3-branes can be responsible for compactification from six to four space-time dimensions, naturally producing the observed hierarchy between electroweak and gravitational forces. The finite radius of the transverse dimensions follows from Einstein's equation, and is exponentially large compared with the scales associated with the 3-brane. The space-time ends on a mild naked singularity at the boundary of the transverse dimensions; nevertheless unitary boundary conditions render the singularity harmless.

On Nonlinear Gauge Theory from a Deformation Theory Perspective
Creators: name: Izawa, K. -I.
Publisher: name: arXiv
Year: 1999
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Nonlinear gauge theory is a gauge theory based on a nonlinear Lie algebra (finite W algebra) or a Poisson algebra, which yields a canonical star product for deformation quantization as a correlator on a disk. We pursue nontrivial deformation of topological gauge theory with conjugate scalars in two dimensions. This leads to two-dimensional nonlinear gauge theory exclusively, which implies its essential uniqueness. We also consider a possible extension to higher dimensions.

Deep learning from 21-cm tomography of the Cosmic Dawn and Reionization

description: The 21-cm power spectrum (PS) has been shown to be a powerful discriminant of reionization and cosmic dawn astrophysical parameters. However, the 21-cm tomographic signal is highly non-Gaussian. Therefore there is additional information which is wasted if only the PS is used for parameter recovery. Here we showcase astrophysical parameter recovery directly from 21-cm images, using deep learning with convolutional neural networks (CNN). Using a database of 2D images taken from 10,000 21-cm lightcones (each generated from different cosmological initial conditions), we show that a CNN is able to recover parameters describing the first galaxies: (i) Tvir , their minimum host halo virial temperatures (or masses) capable of hosting efficient star formation; (ii) ζ , their typical ionizing efficiencies; (iii) LX/SFR , their typical soft-band X-ray luminosity to star formation rate; and (iv) E0 , the minimum X-ray energy capable of escaping the galaxy into the IGM. For most of their allowed ranges, log Tvir and log LX/SFR are recovered with < 1% uncertainty, while ζ and E0 are recovered within 10% uncertainty. Our results are roughly comparable to the accuracy obtained from Monte Carlo Markov Chain sampling of the PS with 21CMMC for the two mock observations analyzed previously, although we caution that we do not yet include noise and foreground contaminants in this proof-of-concept study.
Developing genetic and biological systems for the study of Epstein Barr virus strain diversity
Creators: name: Ba Abdullah, Mohammed
Publisher: name: Imperial College London

description: Epstein-Barr virus is a ubiquitous gamma herpesvirus that can cause several types of lymphoma and carcinoma. Different viruses have different properties such as lytic reactivation, cell tropism, and oncogenesis, but the genetic determinants of these varied phenotypes are not fully known. There is a need for a better understanding of what constitutes wild-type EBV, as a background against which to identify mutations and/or polymorphisms associated with diseases. Most recent EBV sequencing projects through next-generation sequencing have ignored analysing large repeat regions as their assembly is technically challenging with short- read sequencing technologies. In this thesis, a strategy was developed to assemble and analyse in-depth repeat regions using short-read sequencing data. I have assembled and analysed internal repeat 1 (IR1) for 76 strains and the terminal repeat (TR) for 31 strains. The IR1 sequences showed that the latency promoter Wp, the EBNA-LP W1 and W2 exons, and the short intron between them are highly conserved, as are two regions of unknown function within BWRF1 open reading frame. The length of BWRF1 is not the same in all strains. I show that TR is highly variable across strains but includes conserved regions of known functions (e.g. packaging signals sites) and unknown function. Analysis showed that IR1 and TR are generally heterogeneous and this heterogeneity seems to arise from spontaneous mutation as well as from interstrain recombination. IR1 heterogeneity in tumour-derived strains suggested a larger degree of inter-strain recombination, raising the possibility that this may contribute to EBV pathology. We also identified a novel stop codon in one copy of the W1 exon of the commonly used laboratory strain of EBV, B95.8 and showed that this mutation reduced EBNA-LP protein production and the quality of transformation. Our strategy has highlighted the importance of studying the heterogeneity of repeat regions and shown some approaches that can improve the quality of the final sequence. To study the biological properties of EBV, I tried to develop a method to produce circulating EBV viruses by inducing lytic cycle in spontaneous LCLs (sLCLs) and also by cloning EBVs as BACs. sLCLs were very resistant to lytic induction stimuli. I succeeded in cloning the EBV strain P3HR1 as BAC, but was unable to repeat this consistently, highlighting the difficulty of generating EBV-BACs in latent B cells. The constructed P3HR1-BAC would potentially be useful for studying EBV type 2 biology.

description: Quantum information scrambling has attracted much attention amid the effort to reconcile the conflict between quantum-mechanical unitarity and the thermalizaiton-irreversibility in many-body systems. Here we propose an unconventional mechanism to generate quantum information scrambling through a high-complexity mapping from logical to physical degrees-of-freedom that hides the logical information into non-separable many-body-correlations. Corresponding to this mapping, we develop an algorithm to efficiently sample a Slater-determinant wavefunction and compute all physical observables in dynamics with a polynomial cost in system-size. The system shows information scrambling in the quantum many-body Hilbert space characterized by the spreading of Hamming-distance. At late time, we find emergence of classical diffusion dynamics in this quantum many-body system. We establish that the operator-mapping enabled growth in out-of-time-order-correlator exhibits exponential-scrambling behavior. The quantum information-hiding mapping approach may shed light on the understanding of fundamental connections among computational complexity, information scrambling and quantum thermalization.

A Semantics and Complete Algorithm for Subsumption in the CLASSIC Description Logic

description: This paper analyzes the correctness of the subsumption algorithm used in CLASSIC, a description logic-based knowledge representation system that is being used in practical applications. In order to deal efficiently with individuals in CLASSIC descriptions, the developers have had to use an algorithm that is incomplete with respect to the standard, model-theoretic semantics for description logics. We provide a variant semantics for descriptions with respect to which the current implementation is complete, and which can be independently motivated. The soundness and completeness of the polynomial-time subsumption algorithm is established using description graphs, which are an abstracted version of the implementation structures used in CLASSIC, and are of independent interest.

description: A deformed Nahm equation for the BPS equation in the noncommutative N=4 supersymmetric U(2) Yang-Mills theory is obtained. Using this, we constructed explicitly a monopole solution of the noncommutative BPS equation to the linear order of the noncommutativity scale. We found that the leading order correction to the ordinary SU(2) monopole lies solely in the overall U(1) sector and that the overall U(1) magnetic field has an expected long range component of magnetic dipole moment.
