Local measurements of nonlocal observables and the relativistic reduction process

description: In this paper we reconsider the constraints which are imposed by relativistic requirements to any model of dynamical reduction. We review the debate on the subject and we call attention on the fundamental contributions by Aharonov and Albert. Having done this we present a new formulation, which is much simpler and more apt for our analysis, of the proposal put forward by these authors to perform measurements of nonlocal observables by means of local interactions and detections. We take into account recently proposed relativistic models of dynamical reduction and we show that, in spite of some mathematical difficulties related to the appearence of divergences, they represent a perfectly appropriate conceptual framework which meets all necessary requirements for a relativistic account of wave packet reduction. Subtle questions like the appropriate way to deal with counterfactual reasoning in a relativistic and nonlocal context are also analyzed in detail.

description: A two-dimensional periodic array of scatterers has been introduced to a single layer of graphene in the presence of an external magnetic field perpendicular to the graphene layer. The eigenvalue equation for such a system has been solved numerically to display the structure of split Landau subbands as functions of both wave number and magnetic flux. The effects of pseudo-spin coupling and Landau subbands mixing by a strong scattering potential have been demonstrated. Additionally, we investigated the square barrier tunneling problem when magnetic field is present, as well as demonstrate the crucial difference in the modulated band structure between graphene and the twodimensional electron gas. The low-magnetic field regime is particularly interesting for Dirac fermions and has been discussed. Tunneling of Dirac electrons through a magnetic potential barrier has been investigated to complement the reported results on electrostatic potential scattering in the presence of an ambient magnetic field.

description: Aseptic osteonecrosis (ONA) is a common osteopathy with a wide variety of etiologies. It is usually unifocal or multifocal. It preferably touches the hip, the shoulder and the knee. It can be disabling at a late stage, thus requiring early diagnosis. The most common etiologies are systemic corticosteroids and dyslipidemias. Magnetic resonance imaging has a high sensitivity and specificity. It remains the examen of choice as soon as the diagnosis is suspected. We report a case of bifocal aseptic osteonecrosis occurring after cyclosporine treatment for idiopathic medullary aplasia. The direct accountability of ciclosporin for the etiopathogenesis of this case is difficult to establish, but it represents a possible additional risk factor.
description: L’ostéonécrose aseptique (ONA) est une ostéopathie fréquente d’étiologies variées. Elle est généralement uni ou bifocale. Elle touche préférentiellement la hanche, l’épaule puis le genou. Elle peut être invalidante à un stade tardif, nécessitant ainsi un diagnostic précoce. Plusieurs étiologies sont possibles dominées par la corticothérapie générale et les dyslipidémies. L’imagerie par résonance magnétique possède une forte sensibilité et spécificité diagnostiques et reste l’examen de choix dès la suspicion diagnostique. Nous rapportant dans cette observation un cas d’ostéonécrose aseptique bifocale survenant au décours d’un traitement par ciclosporine pour une aplasie médullaire idiopathique. L’imputabilité directe de la ciclosporine dans l’étiopathogénie de ce cas est difficile à établir mais il représente un possible facteur de risque supplémentaire.

description: We extend the framework of a posteriori error estimation by preconditioning in [Li, Y., Zikatanov, L.: Computers \& Mathematics with Applications. \textbf{91}, 192-201 (2021)] and derive new a posteriori error estimates for H(curl)-elliptic two-phase interface problems. The proposed error estimator provides two-sided bounds for the discretization error and is robust with respect to coefficient variation under mild assumptions. For H(curl) problems with constant coefficients, the performance of this estimator is numerically compared with the one analyzed in [Schöberl, J.: Math.~Comp. \textbf{77}(262), 633-649 (2008)].

description: The G/G WZW model results from the WZW-model by a standard procedure of gauging. G/G WZW models are members of Dirac sigma models, which also contain twisted Poisson sigma models as other examples. We show how the general class of Dirac sigma models can be obtained from a gauging procedure adapted to Lie algebroids in the form of an equivariantly closed extension. The rigid gauge groups are generically infinite dimensional and a standard gauging procedure would give a likewise infinite number of 1-form gauge fields; the proposed construction yields the requested finite number of them. Although physics terminology is used, the presentation is kept accessible also for a mathematical audience.

Synthesis, characterisation, and application of novel aluminium initiators for the ring-opening polymerisation of cyclic esters
Creators: name: Gesslbauer, Sami
Publisher: name: Imperial College London
Year: 2021

description: The salen and salan ligands are ligand families which have been extensively studied in the field of ring-opening polymerisation (ROP) catalysis. However, little is known about the behaviour of their ortho-aminophenol analogue in which the nitrogen atoms are directly connected to the aromatic moieties. This ligand scaffold (herein referred to as catam) has been previously complexed with early and late transition metals. Interestingly, no aluminium complexes bearing a catam ligand have been reported and little data exists on the use of catam complexes in the ROP of cyclic esters. Of those, the monomer lactide (LA) has been garnering considerable attention as it presents itself as a sustainable alternative to common polymers. This thesis describes the preparation and characterisation of aluminium complexes bearing catam ligands and their subsequent application in the ROP of rac-LA and other cyclic esters. Even though aluminium complexes generally exhibit low activities in the polymerisation of cyclic esters, many of the described aluminium catam complexes were found to be highly active at room temperature with stereoselectivities ranging from slightly isoselective to highly heteroselective, placing them among the most active Al catalysts to date. Chapter 2 focusses on the catam ligands tethered by either 2,2-dimethyl-1,3-propanediamine or 1,2-ethanediamine and the synthesis and characterisation of their corresponding Al complexes. The NH moieties of the ligand were found to form beneficial non-covalent interactions with the substrate, which is thought to be at the root of the observed activity. Seeking an improvement in isoselectivity, the synthesis and application of chiral aluminium complexes bearing a chiral catam ligand is detailed in Chapter 3. Neither the enantiopure nor the racemic catalysts afforded stereoregular polylactic acid. However, the enantiopure catalysts were able to polymerise enantiopure LA with unprecedented activities. The lack of selectivity in the polymerisation of rac-LA was traced back to polymeryl exchange events which lead to quasi-random insertions of LA. Furthermore, polymerisation of an achiral monomer (ε- caprolactone) was slower when the racemic catalyst was used which was traced back to aggregation being favoured when both enantiomers of a catalyst are present. Chapter 4 describes the synthesis of aluminium complexes bearing a phenylene-tethered catam ligand. The corresponding Al chloro complexes was found to be redox-active. This feature was exploited in ROP. The reduced state was able to polymerise rac-LA with good activities whilst the oxidised state preferentially polymerised cyclohexene oxide. Using an oxidising (e.g. FcBArF) and reducing agent (e.g. CoCp2), it was possible to readily switch the complex between both states and selectively polymerise one monomer over the other.

Urban air pollution modelling with machine learning using fixed and mobile sensors
Creators: name: Song, Jun
Publisher: name: Imperial College London
Year: 2021

description: Detailed air quality (AQ) information is crucial for sustainable urban management, and many regions in the world have built static AQ monitoring networks to provide AQ information. However, they can only monitor the region-level AQ conditions or sparse point-based air pollutant measurements, but cannot capture the urban dynamics with high-resolution spatio-temporal variations over the region. Without pollution details, citizens will not be able to make fully informed decisions when choosing their everyday outdoor routes or activities, and policy-makers can only make macroscopic regulating decisions on controlling pollution triggering factors and emission sources. An increasing research effort has been paid on mobile and ubiquitous sampling campaigns as they are deemed the more economically and operationally feasible methods to collect urban AQ data with high spatio-temporal resolution. The current research proposes a Machine Learning based AQ Inference (Deep AQ) framework from data-driven perspective, consisting of data pre-processing, feature extraction and transformation, and pixelwise (grid-level) AQ inference. The Deep AQ framework is adaptable to integrate AQ measurements from the fixed monitoring sites (temporally dense but spatially sparse), and mobile low-cost sensors (temporally sparse but spatially dense). While instantaneous pollutant concentration varies in the micro-environment, this research samples representative values in each grid-cell-unit and achieves AQ inference at 1 km \times 1 km pixelwise scale. This research explores the predictive power of the Deep AQ framework based on samples from only 40 fixed monitoring sites in Chengdu, China (4,900 {\mathrm{km}}^\mathrm{2}, 26 April - 12 June 2019) and collaborative sampling from 28 fixed monitoring sites and 15 low-cost sensors equipped with taxis deployed in Beijing, China (3,025 {\mathrm{km}}^\mathrm{2}, 19 June - 16 July 2018). The proposed Deep AQ framework is capable of producing high-resolution (1 km \times 1 km, hourly) pixelwise AQ inference based on multi-source AQ samples (fixed or mobile) and urban features (land use, population, traffic, and meteorological information, etc.). This research has achieved high-resolution (1 km \times 1 km, hourly) AQ inference (Chengdu: less than 1% spatio-temporal coverage; Beijing: less than 5% spatio-temporal coverage) with reasonable and satisfactory accuracy by the proposed methods in urban cases (Chengdu: SMAPE \mathrm{<} 20%; Beijing: SMAPE \mathrm{<} 15%). Detailed outcomes and main conclusions are provided in this thesis on the aspects of fixed and mobile sensing, spatio-temporal coverage and density, and the relative importance of urban features. Outcomes from this research facilitate to provide a scientific and detailed health impact assessment framework for exposure analysis and inform policy-makers with data driven evidence for sustainable urban management.

description: We analyze a crossover between ergodic and non-ergodic regimes in an interacting spin chain with a dilute density of impurities, defined as spins with a strong local field. The dilute limit allows us to unravel some finite size effects and propose a mechanism for the delocalization of these impurities in the thermodynamic limit. In particular we show that impurities will always relax by exchanging energy with the rest of the chain. The relaxation rate only weakly depends on the impurity density and decays exponentially, up to logarithmic corrections, with the field strength. We connect the relaxation to fast operator spreading and show that the same mechanism destabilizes the recursive construction of local integrals of motion at any impurity density. In the high field limit, impurities will appear to be localized, and the system will be non-ergodic, over a wide range of system sizes. However, this is a transient effect and the eventual delocalization can be understood in terms of a flowing localization length.

description: MAXI J1659-152 was discovered on 2010 September 25 as a new X-ray transient, initially identified as a gamma-ray burst, but was later shown to be a new X-ray binary with a black hole as the most likely compact object. Dips in the X-ray light curves have revealed that MAXI J1659-152 is the shortest period black hole candidate identified to date. Here we present the results of a large observing campaign at radio, sub-millimeter, near-infrared (nIR), optical and ultraviolet (UV) wavelengths. We have combined this very rich data set with the available X-ray observations to compile a broadband picture of the evolution of this outburst. We have performed broadband spectral modeling, demonstrating the presence of a spectral break at radio frequencies and a relationship between the radio spectrum and X-ray states. Also, we have determined physical parameters of the accretion disk and put them into context with respect to the other parameters of the binary system. Finally, we have investigated the radio-X-ray and nIR/optical/UV-X-ray correlations up to ~3 years after the outburst onset to examine the link between the jet and the accretion disk, and found that there is no significant jet contribution to the nIR emission when the source is in the soft or intermediate X-ray spectral state, consistent with our detection of the jet break at radio frequencies during these states.

description: The saddle-node bifurcation on an invariant circle (SNIC) is one of the codimension-one routes to creation or destruction of a periodic orbit in a continuous-time dynamical system. It governs the transition from resting behaviour to periodic spiking in many class I neurons, for example. Here, as a first step towards theory of networks of such units the effect of weak coupling between two systems with a SNIC is analysed. Two crucial parameters of the coupling are identified, which we call δ_1 and δ_2. Global bifurcation diagrams are obtained here for the "mutualistic" case δ_1 δ_2 > 0. According to the parameter regime, there may coexist resting and periodic attractors, and there can be quasiperiodic attractors of torus or cantorus type, making the behaviour of even such a simple system quite non-trivial. In a second paper we will analyse the mixed case δ_1 δ_2 < 0 and summarise the conclusions of this study.

Grazie all’analisi dei campioni di suolo lunare raccolti durante le missioni Apollo, si è scoperto che la vaporizzazione da impatto è il processo principale con cui la Luna ha generato e sostenuto la sua atmosfera estremamente sottile nel corso di miliardi di anni. Si è arrivati a questa conclusione misurando il rapporto specifico tra isotopi leggeri e pesanti presenti nel suolo lunare. Tutti i dettagli su Science Advances

Mathematical, Thermodynamical, and Experimental Necessity for Coarse Graining Empirical Densities and Currents in Continuous Space

description: We present general results on fluctuations and spatial correlations of the coarse-grained empirical density and current of Markovian diffusion in equilibrium or non-equilibrium steady states on all time scales. We unravel a deep connection between current fluctuations and generalized time-reversal symmetry, providing new insight into time-averaged observables. We highlight the essential role of coarse graining in space from mathematical, thermodynamical, and experimental points of view. Spatial coarse graining is required to uncover salient features of currents that break detailed balance, and a thermodynamically "optimal" coarse graining ensures the most precise inference of dissipation. Defined without coarse graining, the fluctuations of empirical density and current are proven to diverge on all time scales in dimensions higher than one, which has far-reaching consequences for the central-limit regime in continuous space. We apply the results to examples of irreversible diffusion. Our findings provide new intuition about time-averaged observables and allow for a more efficient analysis of single-molecule experiments.

description: We study an inverse problem for the fractional wave equation with a potential by the measurement taking on arbitrary subsets of the exterior in the space-time domain. We are interested in the issues of uniqueness and stability estimate in the determination of the potential by the exterior Dirichlet-to-Neumann map. The main tools are the qualitative and quantitative unique continuation properties for the fractional Laplacian. For the stability, we also prove that the log type stability estimate is optimal. The log type estimate shows the striking difference between the inverse problems for the fractional and classical wave equations in the stability issue. The results hold for any spatial dimension $n\in \N$.

description: A new test of Lorentz invariance in the weak interactions has been made by searching for variations in the decay rate of spin-polarized 20Na nuclei. This test is unique to Gamow-Teller transitions, as was shown in the framework of a recently developed theory that assumes a Lorentz symmetry breaking background field of tensor nature. The nuclear spins were polarized in the up and down direction, putting a limit on the amplitude of sidereal variations of the form |(Γ_{up} - Γ_{down})| / (Γ_{up} + Γ_{down}) < 3 * 10^{-3}. This measurement shows a possible route toward a more detailed testing of Lorentz symmetry in weak interactions.

Quantitative analysis of intra-Golgi transport reveals inter-cisternal exchange for all cargo

description: The mechanisms controlling the transport of proteins across the Golgi stack of mammalian and plant cells is the subject of intense debate, with two models, cisternal progression and inter-cisternal exchange, emerging as major contenders. A variety of transport experiments have claimed support for each of these models. We reevaluate these experiments using a single quantitative coarse-grained framework of intra-Golgi transport that accounts for both transport models and their many variants. Our analysis makes a definitive case for the existence of inter-cisternal exchange both for small membrane proteins (VSVG) and large protein complexes (procollagen) -- this implies that membrane structures larger than the typical protein-coated vesicles must be involved in transport. Notwithstanding, we find that current observations on protein transport cannot rule out cisternal progression as contributing significantly to the transport process. To discriminate between the different models of intra-Golgi transport, we suggest experiments and an analysis based on our extended theoretical framework that compare the dynamics of transiting and resident proteins.
