description: Hypothetical oscillations of probe photons into axion-like particles might be revealed by exploiting the strong fields of high-intensity laser pulses. Considering an arbitrary plane-wave background, we determine the polarization tensor induced by the quantum fluctuations of the axion field and use it to calculate how the polarimetric properties of an initially linear-polarized probe beam are modified. We find that various experimental setups based on contemporary facilities and instrumentation might lead to new exclusion bounds on the parameter space of these particle candidates. The impact of the pulse shape on the discovery potential is studied via a comparison between the cases in which the wave is modulated by a Gaussian envelope and a $\sin^2$ profile. This analysis shows that the upper limits resulting from the ellipticity are relatively insensitive to this change, whereas those arising from the rotation of the polarization plane turn out to be more dependent on the field shape.

description: Complex networks have emerged as a simple yet powerful framework to represent and analyze a wide range of complex systems. The problem of ranking the nodes and the edges in complex networks is critical for a broad range of real-world problems because it affects how we access online information and products, how success and talent are evaluated in human activities, and how scarce resources are allocated by companies and policymakers, among others. This calls for a deep understanding of how existing ranking algorithms perform, and which are their possible biases that may impair their effectiveness. Well-established ranking algorithms (such as the popular Google's PageRank) are static in nature and, as a consequence, they exhibit important shortcomings when applied to real networks that rapidly evolve in time. The recent advances in the understanding and modeling of evolving networks have enabled the development of a wide and diverse range of ranking algorithms that take the temporal dimension into account. The aim of this review is to survey the existing ranking algorithms, both static and time-aware, and their applications to evolving networks. We emphasize both the impact of network evolution on well-established static algorithms and the benefits from including the temporal dimension for tasks such as prediction of real network traffic, prediction of future links, and identification of highly-significant nodes.

description: We study locking phenomena of two strongly coupled, high-quality factor nanomechanical resonator modes subject to a common parametric drive at a single drive frequency. By controlled dielectric gradient forces we tune the resonance frequencies of the flexural in-plane and out-of-plane oscillation of the high stress silicon nitride string through their mutual avoided crossing. For the case of the strong common parametric drive signal-idler generation via parametric oscillation is observed, analogously to the framework of nonlinear optical effects in an optical parametric oscillator. Frequency tuning of the signal and idler resonances is demonstrated. When the resonance frequencies of signal and idler get closer to each other, partial injection locking, injection pulling and complete injection locking to half of the drive frequency occurs depending on the pump strength. Furthermore, satellite resonances, symmetrically off-set from signal and idler by their beat-note, are observed which can be attributed to degenerate four-wave-mixing in the highly nonlinear mechanical oscillations.

description: Bipolar nanopores, with asymmetric charge distributions, can induce significant ionic current rectification (ICR) at ultra-short lengths, finding potential applications in nanofluidic devices, energy conversion, and other related fields. Here, with simulations, we investigated the characteristics of ion transport and modulation of ICR inside bipolar nanopores. With bipolar nanopores of half-positive and half-negative surfaces, the most significant ICR phenomenon appears at various concentrations. In these cases, ICR ratios are independent of electrolyte types. In other cases where nanopores have oppositely charged surfaces in different lengths, ICR ratios are related to the mobility of anions and cations. The pore length and surface charge density can enhance ICR. As the pore length increases, ICR ratios first increase and then approach their saturation which is determined by the surface charge density. External surface charges of nanopores can promote the ICR phenomenon mainly due to the enhancement of ion enrichment inside nanopores by external surface conductance. The effective width of exterior charged surfaces under various conditions is also explored, which is inversely proportional to the pore length and salt concentration, and linearly related to the pore diameter, surface charge density, and applied voltage. Our results may provide guidance for the design of bipolar porous membranes.

description: [transcription] Monsieur,

Vous me faites beaucoup de plaisir en m'apprennant que votre santé se rétablit. Je désire que vous la conserviez longtemps et je vous exhorte à employer pour cela tous les moyens nécessaires. Tous vos amis ont été bien aises de recevoir de vos nouvelles. Ils m'ont chargé de vous faire leurs remerciements de vous dire combien ils vous sont attachés. J'ai communiqué votre lettre à Monsieur l'abbé Barthélemy qui ne se rappelle point qu'elle est de Monsieur Tardia dont vous parlez. Il est à Paris pour quelques jours si vous voulez lui écrire.

Je ne tiens pas absolument à l'explication de la légende que j'ai eu l'honneur de vous envoyer ; cependant, je crois que les explications les plus naturelles et les plus simples sont toujours les meilleurs. Quant à votre observation sur le titre d'Autonomia, je vous répondrai que Vaillant se trompe en attribuant à Diocésarée de Cappadoce la médaille d'Antonin en question : qu'il n'est pas bien certain qu'il y ait [fol. 10 v] eu en Cappadoce une ville du nom de Diocésarée dont les médailles ont presque toujours pour type le mont Argée : que quand même il y aurait eu dans cette province de l'Asie Mineure une ville nommée Diocésarée, il serait toujours bien étonnant que la médaille que Vaillant lui rapporte fût la seule qui eût le titre d'autonome.

Monsieur Pellerin a une autre médaille d'Antoine frappée à Diocésarée et qui a les titres de Sacrée, d'Asyle et d'Autonome, ce qui ne peut être attribué qu'à Diocésarée de Galilée.

Vous avez été informé par la Gazette de la découverte faite à Rennes. Le plat ou l'assiette d'or qu'ils ont nommé patère a été porté ainsi que les médailles au cabinet du Roi. Le travail de l'assiette n'est pas fort précieux. Je crois que l'on en donnera l'explication que vous recevrez sans doute quand elle paraîtra.

La plus intéressante des médailles est une Crispine d'or qui a pour légende au revers Diis conjugalibus, le tout est parfaitement bien conservé.

[fol. 11 r] J'ai l'honneur d'être avec sincère et respectueux attachement,

Monsieur,

Votre très humble et très obéissant serviteur.

Leblond.

What Can Gamma-rays from Space tell us About the Madala Hypothesis?

description: The recent Madala hypothesis, a conjecture that seeks to explain anomalies within Large Hadron Collider (LHC) data (particularly in the transverse momentum of the Higgs boson), is interesting for more than just a statistical hint at unknown and unpredicted physics. This is because the model itself contains additional new particles that may serve as Dark Matter (DM) candidates. These particles interact with the Standard Model via a scalar mediator boson $S$. More interesting still, the conjectured mass range for the DM candidate ($65$ - $100$ GeV) lies within the region of models viable to try explain the recent Galactic Centre (GC) gamma-ray excess seen by Fermi Large Area Telescope (Fermi-LAT) and the High Energy Stereoscopic System (HESS). Therefore, assuming $S$ decays promptly, it should be possible to check what constraints are imposed upon the effective DM annihilation cross-section in the Madala scenario by hunting signatures of $S$ decay that follows DM annihilation within dense astrophysical structures. In order to make use of existing data, we use the Reticulum II dwarf galaxy and the galactic centre gamma-ray excess data sets from Fermi-LAT, and compare these to the consequences of various decay paths for $S$ in the aforementioned environments. We find that, based on this existing data, we can limit $τ$ lepton, quark, direct gamma-ray, and weak boson channels to levels below the canonical relic cross-section. This allows us to set new limits on the branching ratios of $S$ decay, which can rule out a Higgs-like decay branching for $S$, in the case where the Madala DM candidate is assumed to comprise all DM.

description: We explore the scaling behavior of an unsteady flow that is generated by an oscillating body of finite size in a gas. If the gas is gradually rarefied, the Navier-Stokes equations begin to fail and a kinetic description of the flow becomes more appropriate. The failure of the Navier-Stokes equations can be thought to take place via two different physical mechanisms: either the continuum hypothesis breaks down as a result of a finite size effect; or local equilibrium is violated due to the high rate of strain. By independently tuning the relevant linear dimension and the frequency of the oscillating body, we can experimentally observe these two different physical mechanisms. All the experimental data, however, can be collapsed using a single dimensionless scaling parameter that combines the relevant linear dimension and the frequency of the body. This proposed Knudsen number for an unsteady flow is rooted in a fundamental symmetry principle, namely Galilean invariance.

description: Additive manufacturing of polymer bonded magnets is a recently developed technique, for single-unit production, and for structures that have been impossible to manufacture previously. Also new possibilities to create a specific stray field around the magnet are triggered. The current work presents a method to 3D print polymer bonded magnets with a variable magnetic compound density distribution. A low-cost, end-user 3D printer with a mixing extruder is used to mix permanent magnetic filaments with pure PA12 filaments. The magnetic filaments are compounded, extruded, and characterized for the printing process. To deduce the quality of the manufactured magnets with a variable compound density, an inverse stray field framework is used. The effectiveness of the printing process and the simulation method is shown. It can also be used to manufacture magnets that produce a predefined stray field in a given region. Examples for sensor applications are presented. This setup and simulation framework allows the design and manufacturing of polymer bonded permanent magnets which are impossible to create with conventional methods.
Power law spectra and intermittent fluctuations due to uncorrelated Lorentzian pulses

Year: 2016

description: A stochastic model for intermittent fluctuations due to a super-position of uncorrelated Lorentzian pulses is presented. For constant pulse duration, this is shown to result in an exponential power spectral density for the stationary process. A random distribution of pulse durations modifies the frequency spectrum and several examples are shown to result in power law spectra. The distribution of pulse durations does not influence the characteristic function and thus neither the moments nor the probability density function for the random variable. It is demonstrated that the fluctuations are intrinsically intermittent through a large excess kurtosis moment in the limit of weak pulse overlap. These results allow to estimate the basic properties of fluctuations from measurement data and describe the diversity of frequency spectra reported from measurements in magnetized plasmas.

description: The ionic selectivity of nanopores is crucial for the energy conversion based on nanoporous membranes. It can be significantly affected by various parameters of nanopores and the applied fields driving ions through porous membranes. Here, with finite element simulations, the selective transport of ions through nanopores is systematically investigated under three common fields, i.e. the electric field (V), hydrostatic pressure (p), and concentration gradient (C). For negatively charged nanopores, through the quantitative comparison of the cation selectivity (t+) under the three fields, the cation selectivity of nanopores follows the order of t+V > t+c > t+p. This is due to the transport characteristics of cations and anions through the nanopores. Because of the strong transport of counterions in electric double layers under electric fields and concentration gradients, the nanopore exhibits a relatively higher selectivity to counterions. We also explored the modulation of t+ on the properties of nanopores and solutions. Under all three fields, t+ is directly proportional to the pore length and surface charge density, and inversely correlated to the pore diameter and salt concentration. Under both the electric field and hydrostatic pressure, t+ has almost no dependence on the applied field strength or ion species, which can affect t+ in the case of the concentration gradient. Our results provide detailed insights into the comparison and regulation of ionic selectivity of nanopores under three fields which can be useful for the design of high-performance devices for energy conversion based on nanoporous membranes.

description: We report the detection of an ultra-bright fast radio burst (FRB) from a modest, 3.4-day pilot survey with the Australian Square Kilometre Array Pathfinder. The survey was conducted in a wide-field fly's-eye configuration using the phased-array-feed technology deployed on the array to instantaneously observe an effective area of $160$ deg$^2$, and achieve an exposure totaling $13200$ deg$^2$ hr. We constrain the position of FRB 170107 to a region $8'\times8'$ in size (90% containment) and its fluence to be $58\pm6$ Jy ms. The spectrum of the burst shows a sharp cutoff above $1400$ MHz, which could be either due to scintillation or an intrinsic feature of the burst. This confirms the existence of an ultra-bright ($>20$ Jy ms) population of FRBs.

Strong light-matter coupling in plasmonic nanocavities
Creators: name: Kongsuwan, Nuttawut
Publisher: name: Imperial College London
Year: 2019

description: Optical properties of a quantum emitter are drastically modified inside a nanometer-sized gap between two plasmonic nanostructures. At such a nanoscale gap, plasmonic resonances confine light far beyond the diffraction limit and form a nanoscopic optical cavity, called a plasmonic nanocavity. This thesis investigates the optical properties of plasmonic nanocavities and highlights their ability to facilitate strong light-matter interaction. We first study plasmonic nanocavities by treating their resonances as leaky modes with complex eigenfrequencies. By varying their gap morphology, several bright and dark gap plasmonic resonances are discovered, which are essential for understanding how a nanocavity optically influences a quantum emitter. Near-field and far-field investigations also reveal intricate multiple-mode interaction with a quantum emitter. Next, this thesis tackles the misconception that fluorescence emission from a quantum emitter is always quenched through non-radiative decay channels when the emitter is placed closer than 10 nm to a plasmonic nanostructure. We demonstrate the suppression of fluorescence quenching in plasmonic nanocavities due to plasmon hybridization, which enhances the excitation and radiation from the emitter. This enhancement is shown to be strong enough to facilitate single-molecule strong coupling, as evident in its dynamic Rabi oscillations. Finally, an innovative sensing scheme is proposed, which combines immunoassay sensing with strong coupling in plasmonic nanocavities. By chemically linking the antibody-antigen-antibody complex with a quantum emitter label, we show that the proposed scheme provides 1500\% sensitivity enhancement compared to plasmonic sensors with conventional labels. This scheme could lead to the development of plasmonic bio-sensing for single molecules and new pathways towards room-temperature quantum sensing.

This is obtained by proving a local central limit theorem and a local large deviations principle. As an application we prove a formula due to Lebowitz-Percus-Verlet. It gives mean square fluctuations of an extensive observable, like the kinetic energy, in a classical micro canonical ensemble at fixed energy.

description: In this thesis we investigate the intersection of the three fields of random matrix theory, quantum chaos, and PT-symmetric quantum mechanics. The thesis is split into two Parts. The first Part is devoted to random matrix theory, where we first recap some spectral properties of the well-known Gaussian and Ginibre random matrix ensembles. We then introduce some new PT-symmetric random matrix ensembles, exploring the features of their eigenvalues, and discover that one of these new ensembles is spectrally equivalent to one of the existing Ginibre ensembles, whilst to our knowledge the other has no relation with any other existing ensemble. In the second Part, we look at two popular models in quantum chaos known as the baker map and the kicked top, and explore PT-symmetric extensions of them. For the PT-symmetric kicked top we observe new types of classical dynamics where despite the non-Hamiltonian form of the dynamics there are no attractors in the non-chaotic regime, while we observe what appears to be a strange attractor in the deep chaotic regime for even small non-Hermitian parameters. We can observe fingerprints of the classical structures in the quantum Floquet states. Finally, we find similar characteristics in the spectral features of the PT-symmetric versions of both the kicked top and the baker map. These results open the door for myriad avenues to further pursue.

A combined experimental and modelling study for understanding lithium ion behaviour under complex thermal boundary conditions and cell design optimisation
Creators: name: Zhao, Yan

description: Lithium-ion batteries are currently the technology of choice for energy storage in electric vehicles and stationary storage applications. The lifetime and safety of the battery pack are adversely affected as its operating time deviates from ambient condition. Thermal management plays a critical role in minimising these effects. Cooling the electrical tabs of the cell instead of the lithium-ion cell surfaces has been shown to provide better thermal uniformity within the cell and can potentially enable higher usable capacity over its lifetime. However, tab cooling is currently limited by the inability to remove much heat efficiently. This thesis explores the effect of thermal management on lithium-ion performance and the potential design changes that can be made to improve the heat transfer rate while maintaining high thermal uniformity. The development of a two-dimensional electro-thermal modelling framework is presented. The model was used to simulate cell performance and internal states under thermal management boundary conditions. It provides a spatial description of internal states (temperature, current and state of charge) that is difficult measure through experiment. A complete procedure from the parameterisation to validation was provided. Particular focus was paid to thermal modelling of the non-core components and thermal boundaries. The performance of tab cooling and surface cooling system were assessed over a wide range of conditions. It was found that tab cooling provides a much smaller thermal gradient, but it is limited by its heat removal capability. It was hypothesised that increasing the tab cross-sectional area (width x thickness plane) can potentially to improve the limitation. Subsequently, the custom-made cells with varying tab width and position were used to test the hypothesis. The experiment shows that the wider tabs lead to a 14% improvement in the rate of heat transfer. Modelling of the custom-made cells show that a significant heat transfer bottleneck exists between the tabs and the electrode-stack. It was shown that the bottleneck can be opened with a single modification, increasing cross-sectional area of the tabs. A virtual large-capacity automotive cell was modelled to demonstrate that optimised tab cooling can be as effective in removing heat as surface cooling while maintaining the benefit of better thermal, current and state-of-charge homogeneity. These findings could potentially enable the benefit of tab cooling system, higher usable capacity, power and longer lifetime.
Enhancing FPGA applications by applying codecs to data channels

description: FPGA streaming systems are well suited for high-performance computing (HPC) applications, where the parallelism of algorithms can be exploited using pipelines. The usage of FPGAs have become more common with increasing computational demand, since FPGAs have been very effective at meeting the demand. Streaming systems are often implemented on heterogeneous platforms, where hardware accelerators on FPGAs are coupled with CPUs. In such cases, the programmer can achieve an improvement in performance by performing the computationally intensive parts of an algorithm on the FPGA. This way, the relative advantages of both software and hardware computation can be exploited. There are, however, challenges that heterogeneous systems face, which are limiting the performance that can be achieved. This report explores a framework to enhance properties of data channels which transmit data to/from an FPGA kernel. Currently, the framework is applied to a PCI-express channel between an FPGA kernel and a CPU on a heterogeneous CPU-FPGA system by using of spare CPU and FPGA resources. Compute-intensive codecs such as compression are applied at line rate while maintaining the simplicity of a high-level abstraction. Encoding/decoding is done by splitting the data stream into segments and having multiple codec threads processing different segments. Multi-threading in software also allows the overlap of encoding, data transmission and decoding thereby functioning as a software pipeline. Hardware codecs are pipelined. A number of compression codecs are applied using the framework and a model is developed to predict the run-time performance when codecs are applied, without the need to do a full implementation and benchmark.

Conceptual multidisciplinary aircraft design using aero-structural adjoint-based methods
Creators: name: Viti, Andrea
Publisher: name: Imperial College London
Year: 2019

description: Nowadays, on the one hand aircraft design reached very high-fidelity level and aircraft manufacturers obtained such experience that they deeply rely on their design work-flow, models and tests. On the other hand, aircraft architecture struggles to change. Indeed, because of uncertainty and risk management reasons engineers are worried to explore new designs. Moreover, preliminary design models do not enable unconventional aircraft design. By combining the current Overall Aircraft Design models with aero-structural analysis and optimization information, this research work introduces an innovative multidisciplinary approach to be implemented in the preliminary aircraft design phase for novel configurations. The procedure was successfully tested with a forward swept wing-body architecture for which classical preliminary design method was not able to catch physical behaviours due to the wing bending-torsion coupling.

description: In the present paper, we are considering a spatially-flat Friedmann-Robertson-Walker cosmological model, fueled with stiff matter and dust, treated as non-interacting ideal fluid sources. By solving the corresponding Friedmann equation with a non-zero cosmological constant, we are deriving the scale function and the fundamental cosmological parameters. Within a thermodynamic approach, the general form of the Equation of State is obtained, together with the explicit dependence of the energy density and pressure on temperature.

description: Drawdown (resp. drawup) of a stochastic process, also referred as the reflected process at its supremum (resp. infimum), has wide applications in many areas including financial risk management, actuarial mathematics and statistics. In this paper, for general time-homogeneous Markov processes, we study the joint law of the first passage time of the drawdown (resp. drawup) process, its overshoot, and the maximum of the underlying process at this first passage time. By using short-time pathwise analysis, under some mild regularity conditions, the joint law of the three drawdown quantities is shown to be the unique solution to an integral equation which is expressed in terms of fundamental two-sided exit quantities of the underlying process. Explicit forms for this joint law are found when the Markov process has only one-sided jumps or is a Lévy process (possibly with two-sided jumps). The proposed methodology provides a unified approach to study various drawdown quantities for the general class of time-homogeneous Markov processes.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.
