description: In the recording studio, producers of Electronic Dance Music (EDM) spend more time creating, shaping, mixing and mastering sounds, than with compositional aspects or arrangement. They tune the sound by close listening and by leveraging audio metering and audio analysis tools, until they successfully creat the desired sound aesthetics. DJs of EDM tend to play sets of songs that meet their sound ideal. We therefore suggest using audio metering and monitoring tools from the recording studio to analyze EDM, instead of relying on conventional low-level audio features. We test our novel set of features by a simple classification task. We attribute songs to DJs who would play the specific song. This new set of features and the focus on DJ sets is targeted at EDM as it takes the producer and DJ culture into account. With simple dimensionality reduction and machine learning these features enable us to attribute a song to a DJ with an accuracy of 63%. The features from the audio metering and monitoring tools in the recording studio could serve for many applications in Music Information Retrieval, such as genre, style and era classification and music recommendation for both DJs and consumers of electronic dance music.

description: We study the necessary conditions for obtaining infrared finite solutions from the Schwinger-Dyson equation governing the dynamics of the gluon propagator. The equation in question is set up in the Feynman gauge of the background field method, thus capturing a number of desirable features. Most notably, and in contradistinction to the standard formulation, the gluon self-energy is transverse order-by-order in the dressed loop expansion, and separately for gluonic and ghost contributions. Various subtle field-theoretic issues, such as renormalization group invariance and regularization of quadratic divergences, are briefly addressed. The infrared and ultraviolet properties of the obtained solutions are examined in detail, and the allowed range for the effective gluon mass is presented.

description: We explore machine learning methods to detect gravitational waves (GW) from binary black hole (BBH) mergers using deep learning (DL) algorithms. The DL networks are trained with gravitational waveforms obtained from BBH mergers with component masses randomly sampled in the range from 5 to 100 solar masses and luminosity distances from 100 Mpc to, at least, 2000 Mpc. The GW signal waveforms are injected in public data from the O2 run of the Advanced LIGO and Advanced Virgo detectors, in time windows that do not coincide with those of known detected signals. We demonstrate that DL algorithms, trained with GW signal waveforms at distances of 2000 Mpc, still show high accuracy when detecting closer signals, within the ranges considered in our analysis. Moreover, by combining the results of the three-detector network in a unique RGB image, the single detector performance is improved by as much as 70%. Furthermore, we train a regression network to perform parameter inference on BBH spectrogram data and apply this network to the events from the the GWTC-1 and GWTC-2 catalogs. Without significant optimization of our algorithms we obtain results that are mostly consistent with published results by the LIGO-Virgo Collaboration. In particular, our predictions for the chirp mass are compatible (up to 3$σ$) with the official values for 90% of events

title: The Development, Validation, and Integration of Aircraft Carrier Airwakes for Piloted Flight Simulation
Creators: name: Kelly, MF
Publisher: name: University of Liverpool Repository
Year: 2018

description: This thesis reports on an investigation into the effects of ship airwake upon piloted aircraft operating to the United Kingdom’s newly commissioned Queen Elizabeth Class (QEC) aircraft carriers. Piloted flight simulation has been used to inform operation of aircraft to the ship, helping to identify potential wind-speeds/directions requiring high pilot workload prior to First of Class Flight Trials (FOCFT) aboard HMS Queen Elizabeth. The air flow over the QEC was generated using full-scale, time-accurate Computational Fluid Dynamics (CFD) at a range of wind azimuths, with the resultant airwakes incorporated into the flight simulators at both the University of Liverpool and BAE Systems Warton, enabling unsteady aerodynamic loads to be imposed upon rotary-wing and fixed-wing aircraft models, respectively. An additional CFD airwake was generated around a US Navy LHA helicopter carrier, and a comparison was made with real-world anemometer data in an attempt to validate the CFD method used for QEC. LHA at-sea measurements were found to be unreliable for CFD validation due to the inherent unpredictability of at-sea testing. As a result, an experimental validation experiment was recommended to validate the QEC CFD airwakes. A comparison was also made between LHA and QEC, with the twin-island QEC found to have increased turbulence gradient across the flight deck when compared with the single-island LHA. A description is given of the development of a novel Acoustic Doppler Velocimetry (ADV) experiment in a recirculating water channel, for which a 1:202 scale (1.4m) physical model of QEC was produced. To ensure spatial accuracy of ADV probe measurements during validation, an electronic, programmable three degree-of-freedom traverse system has also been incorporated into the water channel, allowing automated positioning of the ADV probes along the SRVL glideslope with sub-millimetre accuracy. Finally, the validated CFD airwakes were incorporated into the HELIFLIGHT-R piloted flight simulator at Liverpool, for which a QEC simulation environment has been developed. Two former Royal Navy test pilots then performed a series of landings to the deck of the QEC in a Sikorsky SH-60 Seahawk, to demonstrate this newly developed capability at Liverpool, and to provide an initial assessment of pilot workload in varying wind speeds and azimuths, prior to real-world FOCFTs. The findings of this initial flight testing is reported in this thesis, as are conclusions and recommendations for future work.
Scale interactions and scaling laws in rotating flows at moderate Rossby numbers and large Reynolds numbers

description: The effect of rotation is considered to become important when the Rossby number is sufficiently small, as is the case in many geophysical and astrophysical flows. Here we present direct numerical simulations to study the effect of rotation in flows with moderate Rossby numbers (down to Ro~0.1) but at Reynolds numbers large enough to observe the beginning of a turbulent scaling at scales smaller than the energy injection scale. We use coherent forcing at intermediate scales, leaving enough room in the spectral space for an inverse cascade of energy to also develop. We analyze the spectral behavior of the simulations, the shell-to-shell energy transfer, scaling laws, and intermittency, as well as the geometry of the structures in the flow. At late times, the direct transfer of energy at small scales is mediated by interactions with the largest scale in the system, the energy containing eddies with k_perp~1, where "perp" refers to wavevectors perpendicular the axis of rotation. The transfer between modes with wavevector parallel to the rotation is strongly quenched. The inverse cascade of energy at scales larger than the energy injection scale is non-local, and energy is transferred directly from small scales to the largest available scale. Also, as time evolves and the energy piles up at the large scales, the intermittency of the direct cascade of energy is preserved while corrections due to intermittency are found to be the same (within error bars) as in homogeneous turbulence.

description: A union of matter bounce and Ekpyrotic scenarios is often studied in an attempt to combine the most promising features of these two models. Since non-perturbative quantum geometric effects in loop quantum cosmology (LQC) result in natural bouncing scenarios without any violation of energy conditions or fine tuning, an investigation of matter-Ekpyrotic bounce scenario is interesting to explore in this quantum gravitational setting. In this work, we explore this unified phenomenological model for a spatially flat Friedmann-Lemaître-Robertson-Walker (FLRW) universe in LQC filled with dust and a scalar field in an Ekpyrotic scenario like negative potential. Background dynamics and the power spectrum of the comoving curvature perturbations are numerically analyzed with various initial conditions and a suitable choice of the initial states. By varying the initial conditions we consider different cases of dust and Ekpyrotic field domination in the contracting phase. We use the dressed metric approach to numerically compute the primordial power spectrum of the comoving curvature perturbations which turns out to be almost scale invariant for the modes which exit the horizon in the matter-dominated phase. But, in contrast with a constant magnitude power spectrum obtained under approximation of a constant Ekpyrotic equation of state using deformed algebra approach in an earlier work, we find that the magnitude of power spectrum changes during evolution. Our analysis shows that the bouncing regime only leaves imprints on the modes outside the scale-invariant regime. However, an analysis of the spectral index shows inconsistency with the observational data, thus making further improvements in such a model necessary.

description: Simulation of time dynamical physical problems has been a challenge for classical computers due to their time-complexity. To demonstrate the dominance of quantum computers over classical computers in this regime, here we simulate a semi-empirical model where two neutral particles interact through Lennard-Jones potential in a one-dimensional system. We implement the above scenario on the IBM quantum experience platform using a 5-qubit real device. We construct the Hamiltonian and then efficiently map it to quantum operators onto quantum gates using the time-evolutionary unitary matrix obtained from the Hamiltonian. We verify the results collected from the QASM-simulator and compare it with that of the 5-qubit real chip ibmqx2.

The housing delivery systems in Beijing : an institutional perspective
Creators: name: Ying, Li
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation is concerned with the dynamics of housing delivery in Beijing, the capital city of China. Over the past four decades, perceptions of housing problems in Beijing and historical conditions have changed. Housing shortages, run-down housing in inner city areas, affordability of commodity housing, and informal housing developments are some examples of housing problems that have developed over the years. However, during the current transition towards a "socialist market system", developing and formulating effective organizational and institutional arrangements to address these substantive housing problems have become the more challenging tasks. The purpose of this study is to elucidate the dynamic changes of organizational and institutional arrangements in housing delivery in Beijing and to identify factors contributing to their performances. Based on the "housing delivery analytical framework" derived from the literature review, the dissertation identifies five housing delivery systems in Beijing: (1) work-unit housing, (2) commodity housing, (3) inner city housing, (4) the "Comfortable Home" housing programme and (5) informal housing. Based on extensive interviews and field research, the dissertation analyzes the unique combination of actors in each housing delivery system, their goals and how they fulfil their role in the process of producing, distributing, and consuming housing. The changes among these arrangements and the reasons for these changes are also discussed. The findings of this study suggest that outcomes of housing delivery systems do not correspond well with the stated objectives or general goals of availability, adequacy, affordability, accessibility, and viability. The dissertation discovers several major reasons for this imperfect correspondence: (1) policy objectives overstress quantitative requirements; (2) policy objectives represent compromises between conflicting values; (3) key interests within the implementation structure are different from policy objectives; and (4) underlying forces beyond housing delivery influence the behaviour of actors In light of the findings, the chief pragmatic implication of the study is that improving housing accessibility should be the key in future housing reforms in Beijing. Housing policies should focus more on managing land, transforming the role of work-units, integrating informal developments, linking comprehensive planning with housing development, forming new community organizations, building housing finance systems, and coordinating housing administration.

description: We investigate the problem of "nonlocal" computation, in which separated parties must compute a function with nonlocally encoded inputs and output, such that each party individually learns nothing, yet together they compute the correct function output. We show that the best that can be done classically is a trivial linear approximation. Surprisingly, we also show that quantum entanglement provides no advantage over the classical case. On the other hand, generalized (i.e. super-quantum) nonlocal correlations allow perfect nonlocal computation. This gives new insights into the nature of quantum nonlocality and its relationship to generalised nonlocal correlations.

description: Using WMAP 3-year data at the locations of close to $\sim 700$ X-ray selected clusters we have detected the amplitude of the thermal Sunyaev-Zeldovich (TSZ) effect at the 15$σ$ level, the highest statistical significance reported so far. Owing to the large size of our cluster sample, we are able to detect the corresponding CMB distortions out to large cluster-centric radii. The region over which the TSZ signal is detected is, on average, four times larger in radius than the X-ray emitting region, extending to $\sim 3h_{70}^{-1}$Mpc. We show that an isothermal $β$ model does not fit the electron pressure at large radii; instead, the baryon profile is consistent with the Navarro-Frenk-White profile, expected for dark matter in the concordance $Λ$CDM model. The X-ray temperature at the virial radius of the clusters falls by a factor $\sim 3-4$ from the central value, depending on the cluster concentration parameter. Our results suggest that cluster dynamics at large radii is dominated by dark matter and is well described by Newtonian gravity.

Time-dependent density-functional theory beyond the adiabatic approximation: insights from a two-electron model system
Creators: name: Ullrich, C. A.
Publisher: name: arXiv

description: Most applications of time-dependent density-functional theory (TDDFT) use the adiabatic local-density approximation (ALDA) for the dynamical exchange-correlation potential Vxc(r,t). An exact (i.e., nonadiabatic) extension of the ground-state LDA into the dynamical regime leads to a Vxc(r,t) with a memory, which causes the electron dynamics to become dissipative. To illustrate and explain this nonadiabatic behavior, this paper studies the dynamics of two interacting electrons on a two-dimensional quantum strip of finite size, comparing TDDFT within and beyond the ALDA with numerical solutions of the two-electron time-dependent Schroedinger equation. It is shown explicitly how dissipation arises through multiple particle-hole excitations, and how the nonadiabatic extension of the ALDA fails for finite systems, but becomes correct in the thermodynamic limit.

description: We formulate a theory of current-induced spin torques in inhomogeneous III-V ferromagnetic semiconductors. The carrier spin-3/2 and large spin-orbit interaction, leading to spin non-conservation, introduce significant conceptual differences from spin torques in ferromagnetic metals. We determine the spin density in an electric field in the weak momentum scattering regime, demonstrating that the torque on the magnetization is intimately related to spin precession under the action of both the spin-orbit interaction and the exchange field characteristic of ferromagnetism. The spin polarization excited by the electric field is smaller than in ferromagnetic metals and, due to lack of angular momentum conservation, cannot be expressed in a simple closed vectorial form. Remarkably, scalar and spin-dependent scattering do not affect the result. We use our results to estimate the velocity of current-driven domain walls.

title: Theoretical and Laboratory Experimental Studies of Vehicle-Excited Bridge Vibration
Creators: name: Yang, JING
Publisher: name: University of Liverpool Repository
Year: 2017

description: Theoretical studies of vehicle-bridge interactions have been conducted extensively, but a relatively much smaller amount of work concerns experimental studies of this problem. Full-scale tests of vehicle-bridge vibrations can be done to estimate the performance of the vehicle-bridge system or validate theoretical models, but are expensive compared with small-scale experiments in a lab. In addition, continuous bridges are paid relatively much less attention compared with simply supported bridges in the literature. This thesis is dedicated to the theoretical and the laboratory experimental studies of a four-span continuous plate structure subjected to moving cars. Firstly, the mode shapes of a multi-span continuous beam are approximated by using a number of sinusoidal functions which are the mode shapes of the beam with simply supported boundaries. The analytical solution of the continuous beam subjected to a moving force can be derived as one simple expression for the whole length of the beam based on the approximated modes, and the contributions of bridge frequencies to the modal responses of the beam would be clearly shown in the analytical solution, which can provide guidance for identifying the modal properties of the beam. This idea is illustrated by a two-span beam. The response of a simple beam subjected to a moving force is compared with that of a two-span continuous beam. The second part of this thesis is about the vehicle-bridge interaction and separation, which are investigated by using the moving sprung mass model. After that, a general approach of simulating vehicle-bridge interactions is applied to a four-span plate structure traversed by one or two moving cars at different speeds. There are two types of situations for two cars: the two cars are either separated or connected together with pitching rotation allowed for each car. The adjacent loads of two-connected-cars are almost equal distance away from each other, which is like a series of moving equidistant loads. A Laser Vibrometer is used to measure the car speeds, and four laser displacement transducers at each span are utilized to capture the structural responses. The theoretical model of the rig is updated and validated with experimental results. A frequency spectrum analysis of measured structural displacements and an in-depth parametric analysis based on the validated theoretical model are carried out.

description: Attacks on information systems followed by intrusions may cause large revenue losses. The prevention of both is not always possible by just considering information from isolated sources of the network. A global view of the whole system is necessary to recognize and react to the different actions of such an attack. The design and deployment of a decentralized system targeted at detecting as well as reacting to information system attacks might benefit from the loose coupling realized by publish/subscribe middleware. In this paper, we present the advantages and convenience in using this communication paradigm for a general decentralized attack prevention framework. Furthermore, we present the design and implementation of our approach based on existing publish/subscribe middleware and evaluate our approach for GNU/Linux systems.

description: High-resolution observations of edge-on proto-planetary disks in emission from molecular species sampling different critical densities and formation pathways offer the opportunity to trace the vertical chemical and physical structures of protoplanetary disks. Based on analysis of sub-arcsecond resolution Atacama Large Millimeter Array (ALMA) archival data for the edge-on Flying Saucer disk (2MASS J16281370-2431391), we establish the vertical and radial differentiation of the disk CN emitting regions with respect to those of $^{12}$CO and CS, and we model the disk physical conditions from which the CN emission arises. We demonstrate that the disk $^{12}$CO (2-1), CN (2-1), and CS J=5-4 emitting regions decrease in scale height above the midplane, such that 12CO, CN, and CS trace layers of increasing density and decreasing temperature. We find that at radii > 100 au from the central star, CN emission arises predominantly from intermediate layers, while in the inner region of the disk, CN appears to arise from layers closer to the midplane. We investigate disk physical conditions within the CN emitting regions, as well as the ranges of CN excitation temperature and column density, via RADEX non-LTE modeling of the three brightest CN hyperfine lines. Near the disk midplane, where we derive densities nH2 ~10$^{7}$ cm$^{-3}$ at relatively low T$_{kin}$ (~12 K), we find that CN is thermalized, while sub-thermal, non-LTE conditions appear to obtain for CN emission from higher (intermediate) disk layers. We consider whether and how the particular spatial location and excitation conditions of CN emission from the Flying Saucer can be related to CN production that is governed, radially and vertically, by the degree of irradiation of the flared disk by X-rays and UV photons from the central star.

title: Analysis of a New Cleaning Technology Based on Supercritical Carbon Dioxide Pre-treatment for Diesel Engine Remanufacturing
Creators: name: Li, Mingzheng
Publisher: name: University of Liverpool Repository
Year: 2018

description: Remanufacturing is the rebuilding of a used product to at least its original performance with a warranty that is equivalent or better than that of the newly manufactured product. It is a vital means in improving manufacturing sustainability, through saving raw materials, reducing carbon emissions and conserving product commercial values. As the one of the demanding steps in remanufacturing process, cleaning is also one polluting stage because of the use of environmental detrimental cleaning agents and the large amount of energy consumptions. The specific aim of the work demonstrated in this thesis is to find an alternative cleaning agent that could achieve the effective cleaning of decommissioned engine parts, in an environmentally greener way. More generally, the study in this thesis uses supercritical carbon dioxide (SC-CO₂) as the green agent to reduce the possible environment loads induced by conventional cleaning technologies and further investigate the feasibility of this method in removing other contaminants as an application extension. Organic contaminants, containing greases, lubricating substances and carbon depositions are the most commonly observed contaminants in a decommissioned engine, and they are analysed by a series of analytical methods to validate the feasibility of SC-CO₂ cleaning in this study. Experiments on grease, lubricating oil and paint coatings cleaning are carried out on the supercritical fluid (SCF) facility with the addition of liquid blasting to remove residues after SC-CO₂ treatment. A new cleaning method combining SC-CO₂ pre-treatment and liquid blasting post-treatment processes is proposed and a comparison is conducted between this method and conventional method (thermal decomposition and shot blasting cleaning). Operation parameters for liquid blasting process are determined through single particle blasting test and the comparison demonstrates the new method has a minimal impact on the surface properties of substrate materials, while the conventional cleaning method has a significant negative impact. Ultimately, the comparative life cycle assessment between two methods demonstrates the new cleaning technology can attain a higher cleanliness with better environmental performances. It is concluded that the SC-CO₂ cleaning could provide a “cleaner production” method for remanufacturing.

description: In 2007 we planted three species of trees (Castanea dentata, Prunus serotina, and Quercus rubra) in all seven possible combinations of one, two and three species mixtures. Additionally, trees were planted at three densities (1, 2, or 3m spacing between trees corresponding to 0.33 trees m-2, 0.5 trees m-2, or 1 trees m-2 respectively). Plots were arranged in a randomised split plot design across three replicate blocks in west-central Indiana (40°26'41.9"N 87°01'46.4"W). These data include: (i) dendrochronology performed in 2018 to estimate wood productivity as basal area increments between 2007 and 2017; (ii) leaf productivity from 2018-2019 estimated from litter traps that were deployed in 2018; (iii) root ingrowth cores that were deployed in 2018 to estimate fine root productivity in 2019, and; (iv) survival of each individual tree in the decade from 2007 to 2017. The code published here was used to analyze the productivity data, to use the survival data to make modern coexistence theory calculations, and to extract and analyze co-occurrence patterns from the USDA FIA data.

description: We attempt to determine the driver for clumping in hot-star winds by extending the measure of the spectral variability level of Galactic Wolf-Rayet stars to by far the hottest known among them, the WN2 star WR 2 and the WO2 stars WR 102 and WR 142. These three stars have T* = 140 kK and 200 kK, the last two being well above the bulk of WR stars with T* ~ 40-120 kK. This full temperature range for WR stars is much broader than that of their O-star progenitors (~30-50 kK), so is better suited to look for any temperature dependence of wind clumping. We have obtained multiple observations with high signal-to-noise, moderate-resolution spectroscopy in search of smallscale variability in the strong emission lines from the dense winds of these three extreme stars, and find a very low-level of variability in both stars. Temperature and terminal velocity are correlated, so faster winds show a lower variability, though this trend goes against any predictions made involving Line Deshadowing Instability (LDI) only, implying that instabilities intrinsic to LDI are not the main source of wind clumping. Instead, it could be taken as support for the suggestion that clumps are caused by a sub-surface convection zone (SSCZ) at T ~ 170 kK, since such an SSCZ would have little opportunity to operate under the hydrostatic surface of these hottest WR stars. It is still possible, however, that an SSCZ-related driver could interact with nonlinear line instability effects to enhance or possibly even produce clumps.

description: In the framework of the Low Emittance Gun (LEG) project, high gradient acceleration of a low emittance electron beam will be necessary. In order to achieve this acceleration a -500 kV, 250 ns FWHM, pulse will be applied in between two electrodes. Those electrodes should sustain the pulsed field without arcing, must not outgass and must not emit electrons. Ion back bombardment, and dark current will be damageable to the electron source as well as for the low emittance beam. Electrodes of commercially available OFE copper, aluminium, stainless steel, titanium and molybdenum were tested following different procedures including plasma glow discharge cleaning.

title: xr and Modal Obligation in Earlier Egyptian
Creators: name: Clayton, JE
Publisher: name: University of Liverpool Repository
Year: 2019

description: In Future at Issue: Tense, Mood and Aspect in Middle Egyptian: Studies in Syntax and Semantics (1990), Pascal Vernus convincingly argued that xr constructions express actions or events that are “governed by an external norm or necessity”, by which he was describing modal obligation. In this study, by close contextual examination of the different xr constructions in Earlier Egyptian and by the application of elements borrowed from linguistic studies of modal necessity, Vernus’s conclusion is refined and expanded upon. It is further argued that the sDm.xr=f, xr=f sDm=f and xr sDm=f forms are not variants of nor developments of one another, as Vernus and others had assumed, but that the first expresses generic necessity, the second case-specific necessity and the third is an erroneous categorisation, being in fact a sDm=f form preceded by a sentence adverb xr which, while still expressing modal necessity, can stand in front of a variety of constructions.

description: We conceived a novel hybrid carrier of a thermal-responsive molecularly imprinted polymer (MIP) and a magnetic thermal seed (MTS) that showed a heat-generating ability under an alternate current (AC) magnetic field. Compared to our previous publications, we modify both the MIP and MTS to improve the feasibility for the hybrid carrier, briefly we have to achieve the accurate size control and narrower size distribution of MTS, and higher molecular recognition/release ability of MIP. Firstly, uniformly sized particles which are expected to show a large heat-generating ability under an AC magnetic field were successfully prepared by controlling the core creation. Then, an MIP targeted for selective adsorption of pemetrexed (PMX), a well-known anti-cancer drug, was prepared using N-carbobenzoxy-l-glutamic acid as a pseudo template. Finally, the preliminary hybridization of the MTS and the MIP-equivalent polymer coating was examined by introducing vinyl groups as methacrylic acid using a ligand exchanging method.
Response of Holographic QCD to Electric and Magnetic Fields

description: We study the response of the Sakai-Sugimoto holographic model of large N_c QCD at nonzero temperature to external electric and magnetic fields. In the electric case we find a first-order insulator-conductor transition in both the confining and deconfining phases of the model. In the deconfining phase the conductor is described by the parallel 8-brane-anti-8-brane embedding with a current of quarks and anti-quarks. We compute the conductivity and show that it agrees precisely with a computation using the Kubo formula. In the confining phase we propose a new kind of 8-brane embedding, corresponding to a baryonic conductor. In the magnetic field case we show that the critical temperature for chiral-symmetry restoration in the deconfined phase increases with the field and approaches a finite value in the limit of an infinite magnetic field. We also illustrate the nonlinear behavior of the electric and magnetic susceptibilities in the different phases.

Anomalous relaxation in binary mixtures: a dynamic facilitation picture

description: Recent computational investigations in polymeric and non-polymeric binary mixtures have reported anomalous relaxation features when both components exhibit very different mobilities. Anomalous relaxation is characterized by sublinear power law behaviour for mean squared displacements, logarithmic decay in dynamic correlators, and a striking concave-to-convex crossover in the latters by tuning the relevant control parameter, in analogy with predictions of the Mode Coupling Theory for state points close to higher-order transitions. We present Monte Carlo simulations on a coarse-grained model for relaxation in binary mixtures. The liquid structure is substituted by a three-dimensional array of cells. A spin variable is assigned to each cell, representing unexcited and excited local states of a mobility field. Changes in local mobility (spin flip) are permitted according to kinetic constraints determined by the mobilities of the neighbouring cells. We introduce two types of cells (``fast'' and ``slow'') with very different rates for spin flip. This coarse-grained model qualitatively reproduces the mentioned anomalous relaxation features observed for real binary mixtures.

description: Data analytics stands to benefit from the increasing availability of datasets that are held without their conceptual relationships being explicitly known. When collected, these datasets form a data lake from which, by processes like data wrangling, specific target datasets can be constructed that enable value-adding analytics. Given the potential vastness of such data lakes, the issue arises of how to pull out of the lake those datasets that might contribute to wrangling out a given target. We refer to this as the problem of dataset discovery in data lakes and this paper contributes an effective and efficient solution to it. Our approach uses features of the values in a dataset to construct hash-based indexes that map those features into a uniform distance space. This makes it possible to define similarity distances between features and to take those distances as measurements of relatedness w.r.t. a target table. Given the latter (and exemplar tuples), our approach returns the most related tables in the lake. We provide a detailed description of the approach and report on empirical results for two forms of relatedness (unionability and joinability) comparing them with prior work, where pertinent, and showing significant improvements in all of precision, recall, target coverage, indexing and discovery times.

description: We report on a new methodological approach to electrodynamics based on a fluidic viewpoint. We develop a systematic approach establishing analogies between physical magnitudes and isomorphism (structure-preserving mappings) between systems of equations. This methodological approach allows us to give a general expression for the hydromotive force, thus re-obtaining the Navier-Stokes equation departing from the an appropriate electromotive force. From this ground we offer a fluidic approach to different kind of issues with interest in propulsion, e.g., the force exerted by a charged particle on a body carrying current; the magnetic force between two parallel currents; the Magnus's force. It is shown how the intermingle between the fluid vectors fields and electromagnetic fields lead to new insights on their dynamics. The new concepts introduced in this work suggest possible applications to electromagnetic (EM) propulsion devices and the mastery of the principles of producing electric fields of required configuration in plasma medium.
