description: The COVID-19 pandemic has rekindled interest in the molecular mechanisms involved in the early steps of infection of cells by viruses. Compared to SARS-CoV-1 which only caused a relatively small albeit deadly outbreak, SARS-CoV-2 has led to fulminant spread and a full-scale pandemic characterized by efficient virus transmission worldwide within a very short time. Moreover, the mutations the virus acquired over the many months of virus transmission, particularly those seen in the Omicron variant, have turned out to result in an even more transmissible virus. Here, we focus on the early events of virus infection of cells. We review evidence that the first decisive step in this process is the electrostatic interaction of the spike protein with heparan sulfate chains present on the surface of target cells: Patches of cationic amino acids located on the surface of the spike protein can interact intimately with the negatively charged heparan sulfate chains, which results in the binding of the virion to the cell surface. In a second step, the specific interaction of the receptor binding domain (RBD) within the spike with the angiotensin-converting enzyme 2 (ACE2) receptor leads to the uptake of bound virions into the cell. We show that these events can be expressed as a semi-quantitative model by calculating the surface potential of different spike proteins using the Adaptive Poison-Boltzmann-Solver (APBS). This software allows visualization of the positive surface potential caused by the cationic patches, which increased markedly from the original Wuhan strain of SARS-CoV-2 to the Omicron variant. The surface potential thus enhanced leads to a much stronger binding of the Omicron variant as compared to the original wild-type virus. At the same time, data taken from the literature demonstrate that the interaction of the RBD of the spike protein with the ACE2 receptor remains constant within the limits of error. Finally, we briefly digress to other viruses and show the usefulness of these electrostatic processes and calculations for cell-virus interactions more generally.

description: Because of the difficulty of interpreting laser data in a meaningful way, safe navigation in vegetated terrain is still a daunting challenge. In this paper, we focus on the segmentation of ladar data using local 3-D point statistics into three classes: clutter to capture grass and tree canopy, linear to capture thin objects like wires or tree branches, and finally surface to capture solid objects like ground terrain surface, rocks or tree trunks. We present the details of the method proposed, the modifications we made to implement it on-board an autonomous ground vehicle. Finally, we present results from field tests using this rover and results produced from different stationary laser sensors.
Interventional techniques in the management of persistent atrial fibrillation
Creators: name: Khan, Habib Rehman
Publisher: name: Imperial College London
Year: 2020

description: Atrial fibrillation (AF) is a common cardiac rhythm problem experienced by patients and comprises an increasing demand on healthcare systems. AF is characterised by advanced neurohormonal remodelling in the atria resulting in dilation and variable degree of atrial fibrosis that can be measured by imaging techniques with difficulty in developing methods of identifying and quantifying left atrial (LA) fibrosis. LA fibrosis can be estimated by measuring LA scar using non-invasive imaging methods such as strain imaging in advanced echocardiography and in cardiac magnetic resonance (CMR) imaging. Achieving rhythm control strategy utilising catheter ablation (CA) has shown to be advantageous in improving quality of life (QOL) in patients with paroxysmal AF. The most effective method in management of AF has remained elusive in non-paroxysmal AF. Thoracoscopic surgical ablation (TSA) has been developed over the last decade by experienced surgeons with some promising early results but has not been investigated in long-standing persistent AF (LSPAF). I have attempted to answer some of the relevant questions that have remained in management of LSPAF by conducting a multicentre randomised control trial comparing efficacy between CA and TSA (CASA-AF RCT) and improvements in quality of life indices. In a sub-study, I measured LA volumes using echocardiography and CMR to determine reverse remodelling and LA function using tissue Doppler imaging and strain imaging to predict AF recurrence. In a CMR sub-study, a novel automatic LA segmentation algorithm was used to quantify LA fibrosis before and after ablation. I was able to quantify the response of the autonomic nervous system to targeted ganglionic plexi (GP) ablation as part of TSA compared to CA by measuring heart rate variability. I am hopeful that the knowledge gained from this thesis will help with an appropriate selection that will improve the management of patients with LSPAF.

description: In this paper, using the techniques of Gauge/gravity duality we explore the hydrodynamic regime of $ z=3 $ Lifshitz fixed points in $ 1+1 $ dimensions. The speed of sound in the non-relativistic plasma turns out to be $\sqrt{3}$, which clearly violates the conjectured upper bound. We identify this as a natural consequence of the Lorentz symmetry breakdown at $ z=3 $ Lifshitz fixed point. In our analysis, we compute bulk viscosity to entropy ratio for quantum field theory dual to Lifshitz gravity in $ 2+1$ dimensions and it turns out that for this particular holographic model this ratio is above the conjectured lower bound.

Total Manhattan distances between the frequencies of different mutations and the mutS A41T and mutS Δ1303 alleles over all samples from the mouse evolution experiment were used to classify mutations as occurring in each hypermutator lineage for examining the base substitution spectra. Mutations with distances < 0.4 to both lineages rose to a high frequency along with each mutS mutation. The cluster of mutations at a distance of ~1.0 from mutS A41T swept within this lineage later in the experiment.

Built and social environment factors associated with stages of change of cycling for transport. Case studies from the pasta project.

Publisher: name: Imperial College London
Year: 2021

description: Cycling for transport provides health and other benefits to participating individuals, wider society and the environment. In a European context, where the uptake of cycling is very varied, this thesis explores how built and social environment factors affect people’s cycling behaviour. Using survey data from the European project Physical Activity through Sustainable Transport Approaches (PASTA), 7,684 participants from seven European cities were assigned to three behavioural stages of change based on the Transtheoretical Model and specifically defined for cycling for transport (Pre-contemplation = “Not thinking about cycling”, Contemplation-Preparation = “Thinking about cycling” and Action-Maintenance = “Cycling”). A statistical model estimated the associations of built and social environment with the stages of change, controlling for socioeconomic status and city. Elements in both the built and social environment have strong associations with the cycling stages of change. For built environment variables, effect sizes are greatest for comfort and for the perceptions of cycling facilities (cycle parking and changing facilities). For social environment variables, social support is the most important effect, and particularly for those not thinking about cycling. The model fits the data well and sensitivity analyses confirm the selection of variables and the generality of the findings across cities. Policy recommendations are tailored to different groups: those who do not even think about cycling need to internalise the message that cycling can be safe and comfortable. For those considering cycling, comfort is important, but having access to parking and changing facilities would also help. Providing opportunities for both of these non-cycling groups to exchange views on cycling with people close to them who are already cycling will help them act. Policies should focus on making cycling for transport accessible for everyone by tailoring interventions targeting these different behavioural change groups.

Investigating neurodegeneration after traumatic brain injury: a longitudinal study of axonal injury
Creators: name: Graham, Neil
Publisher: name: Imperial College London
Year: 2021

description: Traumatic brain injury (TBI) is associated with neurodegeneration and dementia, with Alzheimer’s disease (AD) reported to be more prevalent post-injury. Traumatic axonal injury (TAI) is suspected to trigger progressive neurodegeneration, with axonal damage leading to proteinopathies of tau and amyloid, also features of AD. However, while axonal injury has been difficult to assess clinically, advances in biomarkers now make this more amenable to quantification. This thesis uses advanced fluid and imaging biomarkers to investigate TAI longitudinally and assess how this relates to neurodegeneration post-TBI. I assess biomarkers in plasma and cerebral microdialysate after acute moderate-severe injuries, relating changes to diffusion tensor imaging (DTI) MRI measures of TAI, brain volumetric change and clinical outcomes. In a separate cohort in the chronic phase I assess how DTI measures predict neurodegeneration in comparison with other possible predictors, and characterise the neurodegenerative consequences of injury in comparison with AD and atrophy in healthy ageing. I found that axonal markers neurofilament light (NfL) and tau were markedly increased in concentration within brain extracellular fluid early post-TBI, correlating closely with plasma levels. Subacute plasma NfL related to DTI measures of TAI, predicted clinical outcomes and white matter neurodegeneration, with peak tau predicting grey matter atrophy. In the chronic phase, I found that DTI predicts the extent and pattern of brain atrophy and explains substantially more variance than clinical severity measures. Comparing post-traumatic atrophy with AD and ageing, I show that post-traumatic atrophy patterns are distinctive and reminiscent of axonal injury spatially. These findings provide evidence of axonal injury as a trigger of progressive neurodegeneration and show this can be sensitively measured with fluid and neuroimaging tools both early and late after single moderate-severe injury. These approaches have the potential to improve clinical diagnosis of TAI and its sequelae, prognostication, and facilitate trials of anti-neurodegeneration treatments.

description: We study the dynamical Casimir effect in an electromagnetic cavity containing a Kerr medium. We obtain approximate expressions for the time evolution operator as well as for the number operator in the Heisenberg representation. We have found that the generation of photons from quantum vacuum is strongly affected by the presence of the Kerr medium, sharing physical features with the case of two two-level atoms in a cavity with oscillating walls. The nonlinear medium produces a saturation effect in the photon generation which shows strong oscillations whose frequency increases with the intensity of the nonlinear medium. We expect that these results could be relevant for any experimental study involving the dynamical Casimir effect that is willing to incorporate Kerr nonlinearities.

description: There is strong endorsement of competency-based frameworks for practitioner training and widespread use of group supervision in practitioner training. However, there has been little effort made to understand the components and anatomy of group supervision, or efforts made to evaluate its efficacy. The current study investigates the nature and extent to which abilities and skills within individual and group supervision are similar or distinct from each other. A total of 98 supervisees, across 21 groups, evaluated individual and group supervisor competence of their supervisors (N = 11) using the Supervision Evaluation and Supervisor Competence Scale. Hierarchical cluster analysis revealed that group supervision emerged as a distinct and independent cluster to individual supervision competencies. Additionally, supervisors were rated higher on individual than group supervision competencies. Group supervision should be considered a distinct competency requiring specific skills and therefore would likely benefit from specialised training to deliver competent group supervision. These preliminary results have implications for supervisor training, as well as clinical training programs in Australia and abroad who use group supervision as a form of clinical training. What is already known about this topic:Competency-based supervisory approaches are supported by regulatory authorities.The evaluation of competent group supervision has received inadequate research attention.There are no available measures of group supervision to evaluate supervisor competence.

description: We present a new well-balanced finite volume method within the framework of the finite volume evolution Galerkin (FVEG) schemes. The methodology will be illustrated for the shallow water equations with source terms modelling the bottom topography and Coriolis forces. Results can be generalized to more complex systems of balance laws. The FVEG methods couple a finite volume formulation with approximate evolution operators. The latter are constructed using the bicharacteristics of multidimensional hyperbolic systems, such that all of the infinitely many directions of wave propagation are taken into account explicitly. We derive a well- balanced approximation of the integral equations and prove that the FVEG scheme is well-balanced for the stationary steady states as well as for the steady jets in the rotational frame. Several numerical experiments for stationary and quasi-stationary states as well as for steady jets confirm the reliability of the well-balanced FVEG scheme.

description: Manipulation without prehension is a natural way of handling
objects for both humans and machines. Nonprehensile operations
are appropriate when complete constraint over the object to be
manipulated is either undesirable or impractical, but some control
over the object is desired over its entire trajectory, in order to bring
the object reliably to a desired ﬁnal state. Research to date has
explored only a small portion of this class. We are interested in
controlling the shape of the constraint surfaces so that constraint
and external forces naturally attract the system to the desired state,
even if the object momentarily loses stability during the motion.
We present a preliminary analysis of the nonprehensile orientation
of planar objects by two low friction palms joined at a central
hinge. These palms support an object in a gravitational ﬁeld,
without grasping or gripping. We determine connected regions
of stable states of the object, and give a method of planning part
orientation based on a graph search over these regions, allowing
non-equilibrium transitions between them. We conclude with the
the results of simulations and tests of an example plan.

description: n this paper, we present an adaptive data fusion model that robustly integrates depth and image only perception. Combining dense depth measurements with images can greatly enhance the performance of many computer vision algorithms, yet degraded depth measurements (e.g., missing data) can also cause dramatic performance losses to levels below image-only algorithms. We propose a generic fusion model based on maximum likelihood estimates of fused image-depth functions for both available and missing depth data. We demonstrate its application to each step of a state-of-the-art image-only object instance recognition pipeline. The resulting approach shows increased recognition performance over alternative data fusion approaches.

Novel Method for Incorporating Model Uncertainties into Gravitational Wave Parameter Estimates

Year: 2014
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Posterior distributions on parameters computed from experimental data using Bayesian techniques are only as accurate as the models used to construct them. In many applications these models are incomplete, which both reduces the prospects of detection and leads to a systematic error in the parameter estimates. In the analysis of data from gravitational wave detectors, for example, accurate waveform templates can be computed using numerical methods, but the prohibitive cost of these simulations means this can only be done for a small handful of parameters. In this work a novel method to fold model uncertainties into data analysis is proposed; the waveform uncertainty is analytically marginalised over using with a prior distribution constructed by using Gaussian process regression to interpolate the waveform difference from a small training set of accurate templates. The method is well motivated, easy to implement, and no more computationally expensive than standard techniques. The new method is shown to perform extremely well when applied to a toy problem. While we use the application to gravitational wave data analysis to motivate and illustrate the technique, it can be applied in any context where model uncertainties exist.

Triceratops, except for a few “sports,” lacks fenestrae but is related to the last group. Considering the third group, in dorsal view Anchiceratops and Arrhinoceratops have rectangular frills with well developed epoccipitals. Torosaurus has a cardioid frill, has weakly developed epoccipitals, thinner parietals, and reduced vascular sulci. Since Torosaurus arose from an Arrhinoceratops- like form, a complete fossil record would show a gradation between forms and primitive torosaurs should be intermediate in character. Such a situation seems to exist in the case of Torosaurus utahensis.

description: We present observations by the Fermi Gamma-Ray Space Telescope Gamma-Ray Burst Monitor (GBM) of the nearby (z=0.55) GRB 101219B. This burst is a long GRB, with an associated supernova and with a blackbody component detected in the early afterglow observed by the Swift X-ray Telescope (XRT). Here we show that the prompt gamma-ray emission has a blackbody spectrum, making this the second such burst observed by Fermi GBM. The properties of the blackbody, together with the redshift and our estimate of the radiative efficiency, makes it possible to calculate the absolute values of the properties of the outflow. We obtain an initial Lorentz factor Gamma=138\pm 8, a photospheric radius r_phot=4.4\pm 1.9 \times 10^{11} cm and a launch radius r_0=2.7\pm 1.6 \times 10^{7} cm. The latter value is close to the black hole and suggests that the jet has a relatively unobstructed path through the star. There is no smooth connection between the blackbody components seen by GBM and XRT, ruling out the scenario that the late emission is due to high-latitude effects. In the interpretation that the XRT blackbody is prompt emission due to late central engine activity, the jet either has to be very wide or have a clumpy structure where the emission originates from a small patch. Other explanations for this component, such as emission from a cocoon surrounding the jet, are also possible.

description: We introduce a topological quantum number -- coined dynamical topological order parameter (DTOP) -- that is dynamically defined in the real-time evolution of a quantum many-body system and represented by a momentum space winding number of the Pancharatnam geometric phase. Our construction goes conceptually beyond the standard notion of topological invariants characterizing the wave-function of a system, which are constants of motion under coherent time evolution. In particular, we show that the DTOP can change its integer value at discrete times where so called dynamical quantum phase transitions occur, thus serving as a dynamical analog of an order parameter. Interestingly, studying quantum quenches in one-dimensional two-banded Bogoliubov de Gennes models, we find that the DTOP is capable of resolving if the topology of the system Hamiltonian has changed over the quench. Furthermore, we investigate the relation of the DTOP to the dynamics of the string order parameter that characterizes the topology of such systems in thermal equilibrium.

description: In this deliverable we describe the characteristics of registries that are FAIR by means of a common metadata model that enables interconnecting existing core registries and ontology services needed for implementing Findability and Interoperability in data and services. The focus of this report is on how registries can be designed, extended and/or implemented to better follow the FAIR principles, defining a number of characteristics to expose FAIR, machine actionable behaviour for the registry at three levels: the registry as an informational object or service, information about the registry, and the registry’s machine actionable content. It presents two examples of applications that benefit from FAIR registries and discusses how the FAIR artefacts creating FAIR registries can be the basis for an interconnected network of FAIR resources.

As a by-product, we associate to every multisymplectic form a curved L-infinity-algebra, whose curvature is the multisymplectic form itself.

description: Introdução: A doença de Haff é uma síndrome ocasionada pela contaminação de pessoas por toxinas biológicas presentes em certos tipos de peixes e outros frutos do mar, sendo possível identificar a manifestação dos sintomas atrelados à rabdomiólise em até 24 horas após a ingestão dos pescados. Objetivo: Descrever as evidências científicas nacionais e internacionais disponíveis relacionados aos desafios causados para a saúde pública referente a casos e surtos da Síndrome de Haff. Metodologia: O estudo configurou-se como uma revisão integrativa, em que foi utilizada a estratégia PICo para elaborar a pergunta de pesquisa e utilizou-se artigos da literatura nacional e especialmente internacional para compor a amostra. De acordo com o mapeamento executado em sete base de dados, foram selecionados 13 artigos originais para os resultados que englobam indiretamente os desafios propostos na pergunta de pesquisa. Resultados: Diante da leitura dos estudos, foram pontuados alguns entraves: crescente significativa no número de casos de Haff (51 e 85 casos); expansão do surto para quase todas as regiões do Brasil (Norte: 82,35%; Nordeste: 27,05%); desafio do rastreamento e notificação; não identificação da toxina responsável; negligência das autoridades quanto a intoxicação alimentar, principalmente por DTA (Doenças Transmitidas por Alimentos). Discussão: A doença de Haff não é muito conhecida pela população, resultando na dificuldade de realização do diagnóstico e tratamento. Conclusão: O presente trabalho mostra que é necessário a ampliação de estudos sobre a importância da notificação dos casos, contribuindo com a investigação e o monitoramento adequado, com o intuito de auxiliar no presente cenário de saúde e epidemiológico brasileiro. Além disso, a desinformação acerca da doença, sendo fortalecida sobretudo por um quantitativo mínimo de estudos, é uma problemática que ameaça a saúde pública, pois dificulta no combate a quadro de casos e surtos.

description: Meetings are a very important part of every days life for professionals working in
universities, companies or governmental institutions. In fact, it is estimated that a midlevel
manager or professional spends around 35% of his/her time in meetings. We have
designed a physical awareness system called CAMEO (Camera Assisted Meeting Event
Observer), a hardware/software component to record and monitor people’s activities
in meetings.

CAMEO captures the audio and a high resolution omnidirectional view of the meeting
by stitching images coming from almost concentric cameras. Besides recording
capabilities, CAMEO automatically detects people and automatically learns a personspecific
facial appearance model (PSFAM) for each of the participants. The PSFAMs
allow more robust, reliable and faster tracking and identification. Several novelties in
the video capturing device, multiple person identification and tracking are proposed.
The effectiveness and robustness of the proposed system is demonstrated over several
real time experiments and a large data set of videos.

description: The detailed project report and deliverables of the project "Enhancing Usability and Contributability of RDA DMP Common Standard for Machine-Actionable DMPs" are presented captured in this way for project submission. These attached resources come from prepared repositories that may be published after the approval of the project ouputs. They represent the new way of managing the DMP Common Standard for maDMPs as the specification is also itself machine-actionable and easily extensible. Moreover, on all levels, the best practices to welcome new contributions are adopted (code of conducts, contributing guidelines, crediting contributors, etc.). All these aspects as well as clarification of the design and possible future steps are explained in a detail in the project report document. Several issues with the specification has been also identified and need broader community involvement as it will lead to change of the structure of the maDMPs.

description: Precise characterization of a system's Hamiltonian is crucial to its high-fidelity control that would enable many quantum technologies, ranging from quantum computation to communication and sensing. In particular, non-secular parts of the Hamiltonian are usually more difficult to characterize, even if they can give rise to subtle but non-negligible effects. Here we present a strategy for the precise estimation of the transverse hyperfine coupling between an electronic and a nuclear spin, exploiting effects due to forbidden transitions during the Rabi driving of the nuclear spin. We applied the method to precisely determine the transverse coupling between a Nitrogen-Vacancy center electronic spin and its Nitrogen nuclear spin. In addition, we show how this transverse hyperfine, that has been often neglected in experiments, is crucial to achieving large enhancements of the nuclear Rabi driving.

description: Position estimation for planetary rovers has been typically limited to odometry based on proprioceptive measurements such as the integration of distance traveled and measurement of heading change. Here we present and compare two methods of online visual odometry suited for planetary rovers. Both methods use omnidirectional imagery to estimate motion of the rover. One method is based on robust estimation of optical flow and subsequent integration of the flow. The second method is a full structure-from-motion solution. To make the comparison meaningful we use the same set of raw corresponding visual features for each method. The dataset is an sequence of 2000 images taken during a field experiment in the Atacama desert, for which high resolution GPS ground truth is available.

description: It was shown in a recent paper by Boavida de Brito and Weiss that a well-known construction which to a plain (=monochromatic) topological operad associates a topological category and a functor from it to the category of finite sets is homotopically fully faithful, under mild conditions on the operads. The main result here is a generalization of that statement to k-truncated plain topological operads. A k-truncated operad is a weaker version of operad where all operations have arity at most k.

description: In this work we develop a visual place recognition system for omnidirectional panoramic images that makes use of their full 360 degree circumferential angle of view. The system builds on our previous variant of the sequence SLAM algorithm to include panoramic image rotation alignment for improved image similarity scoring, and bi-directional query and database sequence matching within a Hidden Markov Model (HMM) framework for robust place recognition. Three rotation alignment methods are explored including image pixel registration, and both image cross correlation and zero phase alignment in the spherical Fourier domain. All alignment methods operate using low-resolution images for computational efficiency. Experiments using an outdoor panoramic image dataset demonstrate improved precision recall performance using rotation alignment and bi-directional sequence matching. In particular, place recognition is possible in scenarios where a robot traverses a previous path in the opposite direction.

description: We present a novel approach to 3D shape synthesis of closed surfaces. A curved or polyhedral
3D object of genus zero is represented by a curvature distribution on a spherical mesh
that has nearly uniform distribution with known connectivity among mesh nodes. This curvature
distribution, i.e., the result of forward mapping from shape space to curvature space,
is used as the intrinsic shape representation because it is invariant to rigid transformation
and scale factor. Furthermore, with regularity constraints on the mesh, the inverse mapping
from curvature space to shape space always exists and can be recovered using an iterative
method. Therefore, the task of synthesizing a new shape from two known objects becomes
one of interpolating the two known curvature distributions, and then mapping the interpolated
curvature distribution back to a 3D morph. Using the distance between two curvature
distributions, we can quantitatively control the shape synthesis process to yeild smooth curvature
migration. Experiments show that our method produces smooth and realistic shape
morphs.

description: In this paper we present several multipartite quantum systems featuring the same type of genuine (tripartite) entanglement. Based on a geometric interpretation of the so-called $|W\rangle$ and $|GHZ\rangle$ states we show that the classification of all multipartite systems featuring those and only those two classes of genuine entanglement can be deduced from earlier work of algebraic geometers. This classification corresponds in fact to classification of fundamental subadjoint varieties and establish a connection between those systems, well known in Quantum Information Theory and fundamental simple Lie algebras.
