title: Working in the 'system' and 'lifeworld' : using action research to enhance resilience and attachment in a children's home
Creators: name: Houston, Stan
Publisher: name: Strathprints - University of Strathclyde
Year: 2011

description: Residential child-care workers in the United Kingdom are caught between competing imperatives on a grand scale. On the one hand, they are required to implement an increasing raft of policy, procedure and guidance in relation to safeguarding the welfare of young people looked after by the State. This forms the 'top down' domain of the formal system within which residential care is placed. On the other, they must proactively engage with the young people under their care, develop relationships with them, meet their needs and be sensitive to the daily challenges arising from the group context. This is the existential domain of 'lived' and shared meaning, of expressed need, of emotional pain but also of social connection and inter-personal recognition. I refer to this experiential area as the 'lifeworld' of the young people.

description: We investigate the collective excitations of a single-species Bose gas at T=0 in a harmonic trap where the confinement undergoes some splitting along one spatial direction. We mostly consider onedimensional potentials consisting of two harmonic wells separated a distance 2 z_0, since they essentially contain all the barrier effects that one may visualize in the 3D situation. We find, within a hydrodynamic approximation, that regardless the dimensionality of the system, pairs of levels in the excitation spectrum, corresponding to neighbouring even and odd excitations, merge together as one increases the barrier height up to the current value of the chemical potential. The excitation spectra computed in the hydrodynamical or Thomas-Fermi limit are compared with the results of exactly solving the time-dependent Gross-Pitaevskii equation. We analyze as well the characteristics of the spatial pattern of excitations of threedimensional boson systems according to the amount of splitting of the condensate.

description: Nanomagnetic logic, which makes use of arrays of dipolar-coupled single domain nanomagnets for computation, holds promise as a low power alternative to traditional computation with CMOS. Beyond the use of nanomagnets for Boolean logic, nanomagnets can also be exploited for non-deterministic computational schemes such as edge detection in images and for solving the traveling salesman problem. Here, we demonstrate the potential of arrangements of thermally-active nanomagnets based on artificial spin ice for both deterministic and probabilistic computation. This is achieved by engineering structures that follow particular thermal relaxation pathway consisting of a sequence of reorientations of magnet moments from an initial field-set state to a final low energy output state. Additionally, we demonstrate that it is possible to tune the probability of attaining a particular final low-energy state, and therefore the likelihood of a given output, by modifying the intermagnet distance. Finally, we experimentally demonstrate a scheme to connect several computational building blocks for complex computation.

description: En los últimos años, estamos observando un proceso de abandono de las explotaciones agrícolas en todo el territorio. Aunque las causas pueden ser diversas, las consecuencias pueden ser desastrosas para las cooperativas agroalimentarias. Las razones son obvias. La doble condición de sus socios como propietarios de su propia empresa agroalimentaria a la vez que proveedores, convierten a las cooperativas agroalimentarias en dependientes del producto que entra en sus almacenes. Con el abandono del cultivo, la disminución de la masa social cooperativa ha llevado a una caída del volumen de producto necesario para optimizar las instalaciones.

description: Social networks are the prime channel for the spreading of computer viruses. Yet the study of their propagation neglects the temporal nature of social interactions and the heterogeneity of users' susceptibility. Here, we introduce a theoretical framework that captures both properties. We study two realistic types of viruses propagating on temporal networks featuring Q categories of susceptibility and derive analytically the invasion threshold. We found that the temporal coupling of categories might increase the fragility of the system to cyber threats. Our results show that networks' dynamics and their interplay with users features are crucial for the spreading of computer viruses.

description: Wave chaotic systems underpin a wide range of research activities, from fundamental studies of quantum chaos via electromagnetic compatibility up to more recently emerging applications like microwave imaging for security screening, antenna characterisation or wave-based analog computation. To implement a wave chaotic system experimentally, traditionally cavities of elaborate geometries (bowtie shapes, truncated circles, parallelepipeds with hemispheres) are employed because the geometry dictates the wave field's characteristics. Here, we propose and experimentally verify a radically different paradigm: a cavity of regular geometry but with tunable boundary conditions, experimentally implemented by leveraging a reconfigurable metasurface. Our results set new foundations for the use and the study of chaos in wave physics.

Measuring the galaxy power spectrum with multiresolution decomposition -- II. diagonal and off-diagonal power spectra of the LCRS galaxies

description: The power spectrum estimator based on the discrete wavelet transform (DWT) for 3-dimensional samples has been studied. The DWT estimator for multi-dimensional samples provides two types of spectra with respect to diagonal and off-diagonal modes, which are very flexible to deal with configuration-related problems in the power spectrum detection. With simulation samples and mock catalogues of the Las Campanas redshift survey (LCRS), we show (1) the slice-like geometry of the LCRS doesn't affect the off-diagonal power spectrum with ``slice-like'' mode; (2) the Poisson sampling with the LCRS selection function doesn't cause more than 1-$σ$ error in the DWT power spectrum; and (3) the powers of peculiar velocity fluctuations, which cause the redshift distortion, are approximately scale-independent. These results insure that the uncertainties of the power spectrum measurement are under control. The scatter of the DWT power spectra of the six strips of the LCRS survey is found to be rather small. It is less than 1-$σ$ of the cosmic variance of mock samples in the wavenumber range $0.1 < k < 2$ h Mpc$^{-1}$. To fit the detected LCRS diagonal DWT power spectrum with CDM models, we find that the best-fitting redshift distortion parameter $β$ is about the same as that obtained from the Fourier power spectrum. The velocity dispersions $σ_v$ for SCDM and $Λ$CDM models are also consistent with other $σ_v$ detections with the LCRS. A systematic difference between the best-fitting parameters of diagonal and off-diagonal power spectra has been significantly measured. This indicates that the off-diagonal power spectra are capable of providing information about the power spectrum of galaxy velocity field.

Fair End to End Window Based Congestion Control in Time Varying Data Communication Networks

Year: 2018

description: Communication networks are time-varying and hence, fair sharing of network resources among the users in such a dynamic environment is a challenging task. In this context, a time-varying network model is designed and the shortest user's route is found. In the designed network model, an end to end window-based congestion control scheme is developed with the help of internal nodes or router and the end user can get implicit feedback (RTT and throughput). This scheme is considered as fair if the allocation of resources among users minimizes overall congestion or backlog in the networks. Window update approach is based on a multi-class fluid model and is updated dynamically by considering delays (communication, propagation and queuing) and the backlog of packets in the user's routes. Convergence and stability of the window size are obtained using a Lyapunov function. A comparative study with other window-based methods is also provided.

description: The dynamics of amorphous silicon at low temperatures can be characterized by a sequence of discrete activated events, through which the topological network is locally reorganized. Using the activation-relaxation technique, we create more than 8000 events, providing an extensive database of relaxation and diffusion mechanisms. The generic properties of these events - size, number of atoms involved, activation energy, etc. - are discussed and found to be compatible with experimental data. We introduce a complete and unique classification of defects based on their topological properties and apply it to study of events involving only four-fold coordinated atoms. For these events, we identify and present in detail three dominant mechanisms.

description: In this paper, we review some of the work our group has done in the past few years to obtain the electron self-energy of high temperature superconductors by analysis of angle-resolved photoemission data. We focus on three examples which have revealed: (1) a d-wave superconducting gap, (2) a collective mode in the superconducting state, and (3) pairing correlations in the pseudogap phase. In each case, although a novel result is obtained which captures the essense of the data, the conventional physics used leads to an incomplete picture. This indicates that new physics needs to be developed to obtain a proper understanding of these materials.

description: We report a multiscale modeling study for charged cylindrical nanopores using three modeling levels that include (1) an all-atom explicit-water model studied with molecular dynamics (MD), and reduced models with implicit water containing (2) hard-sphere ions studied with the Local Equilibrium Monte Carlo simulation method (computing ionic correlations accurately), and (3) point ions studied with Poisson-Nernst-Planck (PNP) theory (mean-field approximation). We show that reduced models are able to reproduce device functions (rectification and selectivity) for a wide variety of charge patterns; that is, reduced models are useful in understanding the mesoscale physics of the device (i.e., how the current is produced). We also analyze the relationship of the reduced implicit-water models with the explicit-water model and show that diffusion coefficients in the reduced models can be used as adjustable parameters with which the results of the explicit- and implicit-water models can be related. We find that the values of the diffusion coefficients are sensitive to the net charge of the pore, but are relatively transferable to different voltages and charge patterns with the same total charge.
Progenitors of GRB originated in the dense star cluster

description: The evidences are given for the origin of the GRB progenitors from the ready stellar remnants in result of the dynamical interaction in the dense star clusters. In this way the close binaries of compact objects may form and then merge, often after ejecting from the parent cluster. The GRB may trigger star formation in the gaseous partiall sphere and occurence of the GRB afterglows near the star formation regions may be connected with the successive GRB origins in the same parent cluster. The observed distributions of GRB afterglows in Z and in distance to the galactic centers are compatible with the origin of many GRBs in the (present day classical) globular clusters, which were younger than 2 Gyr at the time of many GRBs events.

description: Using Monte Carlo simulation, we studied the percolation of sticks, i.e. zero-width rods, on a plane paying special attention to the effects of stick alignment and their length dispersity. The stick lengths were distributed in accordance with log-normal distributions, providing a constant mean length with different widths of distribution. Scaling analysis was performed to obtain the percolation thresholds in the thermodynamic limits for all values of the parameters. Greater alignment of the sticks led to increases in the percolation threshold while an increase in length dispersity decreased the percolation threshold. A fitting formula has been proposed for the dependency of the percolation threshold both on stick alignment and on length dispersity.

description: We propose a direct numerical method for the solution of an optimal control problem governed by a two-side space-fractional diffusion equation. The presented method contains two main steps. In the first step, the space variable is discretized by using the Jacobi-Gauss pseudospectral discretization and, in this way, the original problem is transformed into a classical integer-order optimal control problem. The main challenge, which we faced in this step, is to derive the left and right fractional differentiation matrices. In this respect, novel techniques for derivation of these matrices are presented. In the second step, the Legendre-Gauss-Radau pseudospectral method is employed. With these two steps, the original problem is converted into a convex quadratic optimization problem, which can be solved efficiently by available methods. Our approach can be easily implemented and extended to cover fractional optimal control problems with state constraints. Five test examples are provided to demonstrate the efficiency and validity of the presented method. The results show that our method reaches the solutions with good accuracy and a low CPU time.

description: Two decades ago, Sadovskii found an exact solution of a model describing a pseudogap in electron energy spectrum (first introduced by Lee, Rice and Anderson). The discovery of a pseudogap in high-Tc superconductors has revived the interest to his exact solution. I review the model with the emphasis on physical content, point out an error in the original Sadovskii's solution and explain which problem he actually solved. A recent incorporation of Sadovskii's ideas into a description of "hot spots" on the Fermi surface in cuprate superconductors (Schmalian, Pines and Stojkovic) is briefly discussed.

description: We present an analysis to disentangle the connection between physical quantities that characterize the conditions of ionized HII regions -- metallicity ($Z$), ionization parameter ($U$), and electron density ($n_\mathrm{e}$) -- and the global stellar mass ($M_\ast$) and specific star formation rate ($\mathrm{sSFR}=\mathrm{SFR}/M_\ast$) of the host galaxies. We construct composite spectra of galaxies at $0.027 \le z \le 0.25$ from Sloan Digital Sky Survey, separating the sample into bins of $M_\ast$ and sSFR, and estimate the nebular conditions from the emission line flux ratios. Specially, metallicity is estimated from the direct method based on the faint auroral lines [OIII]$λ$4363 and [OII]$λλ$7320,7330. The metallicity estimates cover a wide range from $12+\log\mathrm{O/H}\sim7.6\textrm{--}8.9$. It is found that these three nebular parameters all are tightly correlated with the location in the $M_\ast$--sSFR plane. With simple physically-motivated ansätze, we derive scaling relations between these physical quantities by performing multi regression analysis. In particular, we find that $U$ is primarily controlled by sSFR, as $U \propto \mathrm{sSFR}^{0.43}$, but also depends significantly on both $Z$ and $n_\mathrm{e}$. The derived partial dependence of $U \propto Z^{-0.36}$ is weaker than the apparent correlation ($U\propto Z^{-1.52}$). The remaining negative dependence of $U$ on $n_\mathrm{e}$ is found to be $U \propto n_\mathrm{e}^{-0.29}$. The scaling relations we derived are in agreement with predictions from theoretical models and observations of each aspect of the link between these quantities. Our results provide a useful set of equations to predict the nebular conditions and emission-line fluxes of galaxies in semi-analytic models.

event history analysis

description: In 2014/15, police forces across England, Scotland and Wales received over 300,000 calls relating to missing persons, a figure that appears to be increasing. Despite this growing figure and the workload it places on police forces, there has been a lack of research into the area of missing persons. For most forces, the level of police response that a missing person case requires is set by the risk classification that has been assigned to the case. These levels are ‘Standard Risk’, ‘Medium Risk’ and ‘High Risk’. This project examines the appropriateness of these risk classifications based on how they are assigned and the effect they have on the time it takes to resolve a case. The data used comes from Lancashire Constabulary and contains all missing person reports that were made to the force in 2015. Logistic regression is used to investigate the individual risk factors that best predict a ‘High Risk’ classification and examine how these differ to the risk factors that the police believe indicate higher risk. The main body of the analysis focusses on modelling the time to resolution for missing from home cases as predicted by their risk level and other explanatory variables using event history analysis methods. Kaplan-Meier estimates are used to model the probability of no resolution by risk level. Cox Proportional Hazards Models are then used to determine which factors alongside risk level are significant in their prediction of time to resolution. These models are then extended to account for the effects of repeatedly missing persons with the inclusion of a frailty term. This project concludes that risk classification does have a significant effect on the time to resolution and puts forward the notion that the large amount of cases being classified as ‘Medium Risk’ has absorbed police time and resources and in turn taken these away from the more complex ‘High Risk’ cases which see a slower time to resolution than ‘Medium Risk’ after the first 24 hours of a missing person case being created. Recommendations and possible extensions to the analysis are provided.

Electrical transport is dominated by tunneling or activation through the saddle point junctions, whose typical resistance is calculated as a function of magnetic field. In the Boltzmann regime, this approach yields resistivity laws which agree with recent experiments in both classes of systems. We discuss the origin of dissipation at zero temperature.

description: We present the first D/H measurement in a damped Ly-alpha system at z_abs = 3.025 towards QSO 0347-3819 obtained from the UVES-VLT spectra. The DLA absorber has a metallicity of [Zn/H] = -1.25 and a relatively simple velocity structure, with two dominating components detected in several metal lines. The hydrogen Lyman series can be followed down to Ly12 thanks to the high UV-Blue efficiency of UVES. The best fit of the Lyman series lines, and in particular of Ly5, Ly8, Ly10 and Ly12, relatively free of local contamination, is obtained when the DI absorption is included in the two main components. The measured deuterium column density yields D/H = (2.24+/-0.67) 10^{-5} close to other low D/H values from Lyman limit systems. The corresponding values for the baryon to photon ratio and the baryon density derived from D/H are eta = 6 10^{-10} and Omega_b h^2 = 0.023 respectively.

description: We consider the Einstein-scalar-Gauss-Bonnet theory in the presence of a cosmological constant $Λ$, either positive or negative, and look for novel, regular black-hole solutions with a non-trivial scalar hair. We first perform an analytic study in the near-horizon asymptotic regime, and demonstrate that a regular black-hole horizon with a non-trivial hair may be always formed, for either sign of $Λ$ and for arbitrary choices of the coupling function between the scalar field and the Gauss-Bonnet term. At the far-away regime, the sign of $Λ$ determines the form of the asymptotic gravitational background leading either to a Schwarzschild-Anti-de Sitter-type background ($Λ<0$) or a regular cosmological horizon ($Λ>0$), with a non-trivial scalar field in both cases. We demonstrate that families of novel black-hole solutions with scalar hair emerge for $Λ<0$, for every choice of the coupling function between the scalar field and the Gauss-Bonnet term, whereas for $Λ>0$, no such solutions may be found. In the former case, we perform a comprehensive study of the physical properties of the solutions found such as the temperature, entropy, horizon area and asymptotic behaviour of the scalar field.

description: The intent of this paper is to explore the importance of relationships within Scottish residential child care settings. Whilst making reference to research, theoretical and legislative material, consideration will be given to the ethical and developmental issues surrounding the risk-averse approach to practice believed to be increasingly evident in relation to care provision within contemporary social work in Scotland (Scottish Executive, 2005). With reference to this, I will provide a critical analysis of the way in which riskaverse practice has infiltrated into residential child care practice in relation to meeting the attachment needs and promoting resilience of the looked after and accommodated children and young people to whom they provide a service.

description: We present the first spatially resolved (~0.5 kpc) measurements of the molecular gas depletion time $τ_{depl}$ across the disk of the interacting spiral galaxy NGC\,2276, a system with an asymmetric morphology in various SFR tracers. To estimate $τ_{depl}$, we use new NOEMA observations of the $^{12}$CO(1-0) emission tracing the bulk molecular gas reservoir in NGC 2276, and extinction-corrected H$α$ measurements obtained with the PMAS/PPaK integral field unit for robust estimates of the SFR. We find a systematic decrease in $τ_{depl}$ of 1-1.5 dex across the disk of NGC 2276, with a further, abrupt drop in $τ_{depl}$ of ~1 dex along the galaxy's western edge. The global $τ_{depl}$ in NGC 2776 is $τ_{depl}=0.55$ Gyr, insistent with literature measurements for the nearby galaxy population. Such a large range in $τ_{depl}$ on sub-kpc scales has never previously been observed within an individual isolated or pre-merger system. When using a metallicity-dependent molecular gas conversion factor X$\rm_{CO}$ the variation decreases by 0.5 dex. We attribute the variation in $τ_{depl}$ to the influence of galactic-scale tidal forces and ram pressure on NGC 2276's molecular interstellar medium (ISM). Our observations add to the growing body of numerical and observational evidence that galaxy-galaxy interactions significantly modify the molecular gas properties and star-forming activity within galactic disks throughout the interaction, and not just during the final merger phase.

Displacement monitoring is a critical control for risks associated with potentially sudden slope failures. Instrument measurements are, however, obscured by the presence of scatter. Data filtering methods aim to reduce the scatter and therefore enhance the performance of early warning systems (EWSs). The effectiveness of EWSs depends on the lag time between the onset of acceleration and its detection by the monitoring system such that a timely warning is issued for the implementation of consequence mitigation strategies. This paper evaluates the performance of three filtering methods (simple moving average, Gaussian-weighted moving average, and Savitzky–Golay) and considers their comparative advantages and disadvantages. The evaluation utilized six levels of randomly generated scatter on synthetic data, as well as high-frequency global navigation satellite system (GNSS) displacement measurements at the Ten-mile landslide in British Columbia, Canada. The simple moving average method exhibited significant disadvantages compared to the Gaussian-weighted moving average and Savitzky–Golay approaches. This paper presents a framework to evaluate the adequacy of different algorithms for minimizing monitoring data scatter.

description: The present article analyses the impact on cosmology, in particular on the evolution of cosmological perturbations, of the existence of extra-dimensions. The model considered here is that of a five-dimensional Anti-de Sitter spacetime where ordinary matter is confined to a brane-universe. The homogeneous cosmology is recalled. The equations governing the evolution of cosmological perturbations are presented in the most transparent way: they are rewritten in a form very close to the equations of standard cosmology with two types of corrections: a. corrections due to the unconventional evolution of the homogeneous solution, which change the background-dependent coefficients of the equations; b. corrections due to the curvature along the fifth dimension, which act as source terms in the evolution equations.

description: В данной работе представлены результаты проведенного исследования, посвященного созданию электропроводящих и экранирующих текстильных материалов, основанных на хлопчатобумажной ткани. Процесс металлизации ткани был осуществлен с применением метода химического осаждения меди, в ходе которого использовались растворы сульфата меди (II), цитрата натрия и гипофосфита натрия. Для более глубокого понимания структурных и физико-химических свойств модифицированных образцов были проведены исследования с использованием таких методов, как рентгеноструктурный анализ, сканирующая электронная микроскопия и инфракрасная Фурье-спектроскопия. В результате экспериментов было установлено, что полученные материалы обладают высокой электропроводностью и антистатическими свойствами, что делает их весьма перспективными для применения в защитной одежде, а также в экранирующих текстильных изделиях.
Reaction Zones and Quenched Charged-Particle Systems with Long-Range Interactions

description: We determine the evolving segregated or mixed morphology of charged-particle systems with long-range power-law interactions and overall charge neutrality that have been quenched to a low temperature. Segregated morphology systems are characterized by the size of uniformly charged domains, $L(t)$, the particle separation within the domains, $l_{AA}(t)$, the particle flux-density leaving the domains, $J(t)$, the width of reaction zones between domains, $W(t)$, the particle spacing within the reaction-zones, $l_{AB}(t)$, and the particle lifetime in the reaction-zones, $τ(t)$. Mixed morphology systems are essentially one large reaction zone, with $L \sim l_{AB} \sim l_{AA}$. By relating these quantities through the scaling behavior of particle fluxes and microscopic annihilation rates within reaction-zones, we determine the characteristic time-exponents of these quantities at late times. The morphology of the system, segregated or mixed, is also determined self-consistently. With this unified approach, we consider systems with diffusion and/or long-range interactions, and with either uncorrelated or correlated high-temperature initial conditions. Finally, we discuss systems with particle-like topological defects and electronic systems in various substrate dimensions --- including quantum-hall devices with skyrmions.

description: In this work, we experimentally created and characterized a class of qubit-ququart PPT (positive under partial transpose) entangled states using three nuclear spins on an nuclear magnetic resonance (NMR) quantum information processor. Entanglement detection and characterization for systems with a Hilbert space dimension $\ge 2 \otimes 3$ is nontrivial since there are states in such systems which are both PPT as well as entangled. The experimental detection scheme that we devised for the detection of qubit-ququart PPT entanglement was based on the measurement of three Pauli operators with high precision, and is a key ingredient of the protocol in detecting entanglement. The family of PPT-entangled states considered in the current study are incoherent mixtures of five pure states. All the five states were prepared with high fidelities and the resulting PPT entangled states were prepared with mean fidelity $\ge 0.95$. The entanglement thus detected was validated by carrying out full quantum state tomography (QST).

Single-file Diffusion with Random Diffusion Constants

description: The single-file problem of N particles in one spatial dimension is analyzed, when each particle has a randomly distributed diffusion constant D sampled in a density $ρ(D)$. The averaged one-particle distributions of the edge particles and the asymptotic ($N\gg 1$) behaviours of their transport coefficients (anomalous velocity and diffusion constant) are strongly dependent on the D-distribution law, broad or narrow. When $ρ$ is exponential, it is shown that the average one-particle front for the edge particles does not shrink when N becomes very large, as contrasted to the pure (non-disordered) case. In addition, when $ρ$ is a broad law, the same occurs for the averaged front, which can even have infinite mean and variance. On the other hand, it is shown that the central particle, dynamically trapped by all others as it is, follows a narrow distribution, which is a Gaussian (with a diffusion constant scaling as $N^{-1}$) when the fractional moment $$ exists and is finite; otherwise ($ρ(D)\propto D^{α-1}, α\le\case12$), this density is, far from the origin, a stretched exponential with an exponent in the range $]0, 2]$; then the effective diffusion constant scales as $N^{-β}$, with $β= 1/(2α)$.

description: Dynamical instability is shown to occur in differentially rotating polytropes with N = 3.33 and $T/|W| \gtrsim 0.14$. This instability has a strong m=1 mode, although the m=2, 3, and 4 modes also appear. Such instability may allow a centrifugally-hung core to begin collapsing to neutron star densities on a dynamical timescale. The gravitational radiation emitted by such unstable cores may be detectable with advanced ground-based detectors, such as LIGO II. If the instability occurs in a supermassive star, it may produce gravitational radiation detectable by the space-based detector LISA.

description: This paper introduces a machine for sampling approximate model-X knockoffs for arbitrary and unspecified data distributions using deep generative models. The main idea is to iteratively refine a knockoff sampling mechanism until a criterion measuring the validity of the produced knockoffs is optimized; this criterion is inspired by the popular maximum mean discrepancy in machine learning and can be thought of as measuring the distance to pairwise exchangeability between original and knockoff features. By building upon the existing model-X framework, we thus obtain a flexible and model-free statistical tool to perform controlled variable selection. Extensive numerical experiments and quantitative tests confirm the generality, effectiveness, and power of our deep knockoff machines. Finally, we apply this new method to a real study of mutations linked to changes in drug resistance in the human immunodeficiency virus.
