title: Beyond containment: driving change in residential care : a Queensland, Australia model of therapeutic residential care
Creators: name: Wall, Shelley

Publisher: name: Strathprints - University of Strathclyde
Year: 2013

description: Mercy Family Services is a Non-Government Organisation providing a range of out of home care services, including one 'therapeutic residential' and 12 traditional residential care programmes across South East Queensland, Australia. This paper will examine the implementation of a model of therapeutic residential care developed to address a gap in service delivery identified in the Crime and Misconduct Commission: An Inquiry Into Abuse In Foster Care in January 2004, which found there was a need for more therapeutic treatment programmes in order to assist children and young people with severe psychological and behavioural problems (Crime and Misconduct Commission, 2004). Traditional residential care, with a focus on daily care provision and containment, had limited success in meeting this client group's complex needs and it was apparent that a trauma informed model that sought to provide a 'healing' therapeutic milieu was a sector priority. The paper will provide an overview of the Mercy Family Services' therapeutic residential care model recently implemented in the final of four pilot programmes across Queensland, Australia. Further, the learning gained from the process of development of the model, informed by contemporary literature from within Australia and beyond, will be shared, along with the exciting developments emerging as practice is transformed and influences improvements across our entire network of residential programmes. This paper will explore how the historical context of residential care in Queensland, Australia influenced the development of a model of therapeutic residential service delivery developed to meet the challenge of driving change in an environment where containment models and poor outcomes had resulted in a decline in popularity of residential care. The paper will also detail the Mercy Family Services Therapeutic Residential Care model, a community of care approach that is underpinned by a needsbased, trauma-sensitive, and relationship/attachment-focused framework developed by Dr Redshaw, in response to an opportunity to pilot therapeutic residential care commissioned by the Department of Child Safety after recommendations arising from an inquiry intoabuse in foster care conducted in Queensland in 2004. Finally, the paper will share learning experiences from the implementation of the model into practice and initial outcomes for the young people placed during the first year of operation.

description: The disposition of the colonies of Germany and Turkey at the end of the World War led to the inauguration of the system of mandates. This experiment has attracted much interest because it has involved the widest application of the principles of international administration. The success of the venture has been somewhat surprising to students of government and has raised the question of how far international cooperation can be extended. At the center of the mandate organization is the Permanent Mandates Commission, which has proved to be a very efficient organ. The present study is an attempt to describe its character and to evaluate its work from the first through the thirteenth sessions

description: Using the orbit method we attempt to reveal geometric and algebraic meaning of separation of variables for the integrable systems on coadjoint orbits in an $\mathfrak{sl}(3)$ loop algebra. We consider two types of generic orbits embedded into a common manifold, endowed with two nonsingular Lie-Poisson brackets. We prove that separation of variables on orbits of both types is realized by the same variables of separation. We also construct the integrable systems on these orbits: a coupled 3-component nonlinear Schrödinger equation and an isotropic SU(3) Landau-Lifshitz equation.

description: We show existence and uniqueness of a solution for the non-local vector-valued Allen-Cahn variational inequality in a formulation involving Lagrange multipliers for local and non-local constraints. Furthermore, we propose and analyze a primal-dual active set method for local and non-local vector-valued Allen-Cahn variational inequalities. Convergence of the primal-dual active set algorithm is shown by interpreting the approach as a semi-smooth Newton method and numerical simulations are presented demonstrating its efficiency.

description: Developmental and epileptic encephalopathy (DEE) is a term used to describe cerebral dysfunction resulting from the underlying cause, epilepsy, or both. There is a subset of DEEs in which there is compelling evidence that the regression is directly tied to the epilepsy itself, where the “epileptic encephalopathy” component of DEE is most evident. Infantile epileptic spasm syndrome (IESS) is perhaps the clearest example.

description: Probing signatures of anomalous interactions of the Higgs boson with pairs of weak vector bosons is an important goal of an $e^+e^-$ collider commissioned as a Higgs factory. We perform a detailed analysis of such potential of a collider operating at $250 - 300$ GeV. Mostly using higher dimensional operators in a gauge-invariant framework, we show that substantial information on anomalous couplings can be extracted from the total rates of $s$-and $t$-channel Higgs production. The most obvious kinematic distributions, based on angular dependence of matrix elements, are relatively less sensitive with moderate coefficients of anomalous couplings, unless one goes to higher centre-of-mass energies. Some important quantities to use here, apart from the total event rates, are the ratios of event rates at different energies, ratios of $s$ and $t$-channel rates at fixed energies, and under some fortunate circumstances, the correlated changes in the rates for $W$-boson pair-production. A general scheme of calculating rates with as many as four gauge-invariant operators is also outlined. At the end, we perform a likelihood analysis using phenomenological parametrization of anomalous $HWW$ interaction, and indicate their distinguishability for illustrative values of the strength of such interactions.

Preparation and Characterization of Activated Carbon from Flower Waste Biomass for Methylene blue Removal
Creators: name: Getu Maru
Publisher: name: Zenodo

description: Activated carbon (AC) can be used as an adsorbent to remove pollutants from waste water streams. 520 kg flower biomass waste is generated daily at a single floriculture industry in Ethiopia. Despite AC has been produced from different lignocellulosic biomass waste, utilizing Flower waste biomass (FWB) as a precursor to produce AC has an advantage of being new raw material, easily available, renewable precursor, and can be a way of reducing environmental pollution. This study presents synthesis of AC from FWB by chemical activation method using ZnCl2 and removal of methylene blue (MB) using the as-prepared AC. The parameters in the study were impregnation ratio, carbonization temperature, and carbonization time. Higher BET surface area of 750 m2 g-1, pore volume of 1.91 cm3 g-1 and pore diameter of 1.89 nm was obtained at 1:1 impregnation ratio, 500 °C carbonization temperature, and 1 hr of carbonization time

description: Causal fermion systems are introduced as a general mathematical framework for formulating relativistic quantum theory. By specializing, we recover earlier notions like fermion systems in discrete space-time, the fermionic projector and causal variational principles. We review how an effect of spontaneous structure formation gives rise to a topology and a causal structure in space-time. Moreover, we outline how to construct a spin connection and curvature, leading to a proposal for a “quantum geometry” in the Lorentzian setting. We review recent numerical and analytical results on the support of minimizers of causal variational principles which reveal a “quantization effect” resulting in a discreteness of space-time. A brief survey is given on the correspondence to quantum field theory and gauge theories.

description: We present a family of exact solutions, depending on two parameters $α$ and $b$ (related to the scalar field strength), to the three-dimensional Einstein-scalar field equations with negative cosmological constant $Λ$. For $b=0$ these solutions reduce to the static BTZ family of vacuum solutions, with mass $M = -α$. For $b\neq0$, the solutions become dynamical and develop a strong spacelike central singularity. The $α<0$ solutions are black-hole like, with a global structure topologically similar to that of the BTZ black holes, and a finite effective mass. We show that the near-singularity behavior of the solutions with $α>0$ agrees qualitatively with that observed in numerical simulations of subcritical collapse. We analyze the linear perturbations of the threshold solution, $α=0$, in the $Λ=0$ approximation, and find that it has only one unstable growing mode, which qualifies it as a candidate critical solution for scalar field collapse.

Application of Marginal Economic Analysis to Reservoir Recreation Planning
Creators: name: Sirles, John Ellis, III
name: James, L. Douglas
Publisher: name: Kentucky Water Resources Research Institute, University of Kentucky
Year: 1968

description: Abstract:
Recreation visitation and cost data at three reservoirs in the Ohio River Valley (Rough River, Dewey, and Winton Woods) were analyzed in an attempt to derive a method by which the optimum level of reservoir recreation development could be determined by marginal economic analysis.
The visitation data were used to determine factors expressing the time distribution of facility use, capacity coefficients, and realized benefits. The cost data were used to estimate annual cost, and marginal cost as functions of annual visitation. Marginal cost and marginal benefit data were combined to find the optimum size.
Potential visitation to Winton Woods was estimated, and the marginal benefit per visitor was estimated from travel costs. The potential visitation was combined with the distribution factors for Rough River and Dewey to get the time distribution of reservoir use. Actual visitation was combined with the distribution factors at Winton Woods to get the time distribution of use at actual conditions. These two relationships allowed the reduction in potential benefits due to crowding to be estimated.
The marginal cost curves are combined with the marginal benefit curves to find the optimum visitation to a site. This optimum visitation implies a required reservoir size which can be estimated by use of the distribution factors and capacity coefficients. The required cost for these facilities and the realized benefits can also be estimated.

description: Yield stress materials flow if a sufficiently large shear stress is ap- plied. Although such materials are ubiquitous and relevant for indus- try, there is no accepted microscopic description of how they yield, even in the simplest situations where temperature is negligible and where flow inhomogeneities such as shear bands or fractures are ab- sent. Here we propose a scaling description of the yielding transition in amorphous solids made of soft particles at zero temperature. Our description makes a connection between the Herschel-Bulkley expo- nent characterizing the singularity of the flow curve near the yield stress Σc, the extension and duration of the avalanches of plasticity observed at threshold, and the density P(x) of soft spots, or shear transformation zones, as a function of the stress increment x be- yond which they yield. We argue that the critical exponents of the yielding transition can be expressed in terms of three independent exponents θ, df and z, characterizing respectively the density of soft spots, the fractal dimension of the avalanches, and their duration. Our description shares some similarity with the depinning transition that occurs when an elastic manifold is driven through a random potential, but also presents some striking differences. We test our arguments in an elasto-plastic model, an automaton model similar to those used in depinning, but with a different interaction kernel, and find satisfying agreement with our predictions both in two and three dimensions.

description: Nuclear-spin diffusion in double quantum wells (QWs) is examined by using dynamic nuclear polarization (DNP) at a Landau level filling factor $ν=2/3$ spin phase transition (SPT). The longitudinal resistance increases during the DNP of one of the two QW (the polarization QW) by means of a large applied current and starts to decrease just after the termination of the DNP. On the other hand, the longitudinal resistance of the other QW (the detection QW) continuously increases for approximately 2h after the termination of the DNP of the polarization QW. It is therefore concluded that the nuclear spins diffuse from the polarization QW to the detection QW. The time evolution of the longitudinal resistance of the polarization QW is explained mainly by the nuclear-spin diffusion in the in-plane direction. In contrast, that of the detection QW manifests much slower nuclear diffusion in the perpendicular direction through the AlGaAs barrier.

General pseudo self-adjoint boundary conditions for a 1D KFG particle in a box
Creators: name: De Vincenzo, Salvatore
Publisher: name: arXiv
Year: 2023
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We consider a 1D Klein-Fock-Gordon particle in a finite interval, or box. We construct for the first time the most general set of pseudo self-adjoint boundary conditions for the Hamiltonian operator that is present in the first order in time 1D Klein-Fock-Gordon wave equation, or the 1D Feshbach-Villars wave equation. We show that this set depends on four real parameters and can be written in terms of the one-component wavefunction for the second order in time 1D Klein-Fock-Gordon wave equation and its spatial derivative, both evaluated at the endpoints of the box. Certainly, we write the general set of pseudo self-adjoint boundary conditions also in terms of the two-component wavefunction for the 1D Feshbach-Villars wave equation and its spatial derivative, evaluated at the ends of the box; however, the set actually depends on these two column vectors each multiplied by the singular matrix that is present in the kinetic energy term of the Hamiltonian. As a consequence, we found that the two-component wavefunction for the 1D Feshbach-Villars equation and its spatial derivative do not necessarily satisfy the same boundary condition that these quantities satisfy when multiplied by the singular matrix. In any case, given a particular boundary condition for the one-component wavefunction of the standard 1D Klein-Fock-Gordon equation and using the pair of relations that arise from the very definition of the two-component wavefunction for the 1D Feshbach-Villars equation, the respective boundary condition for the latter wavefunction and its derivative can be obtained. Our results can be extended to the problem of a 1D Klein-Fock-Gordon particle moving on a real line with a point interaction (or a hole) at one point.

description: DAMASK is a unified multi-physics crystal plasticity software, which is used by researchers from all over the world to understand process-structure-property relationship of advanced materials.
 Its modular structure allows for the use of different solvers and enables seamless coupling with various tools for data analysis.
 The core of DAMASK is written in modern Fortran while all tools for pre- and post-processing are written in Python.
 After working as a research software engineer for two years, I found that a major challenge we encounter during development is maintaining a clean structure that allows for long-term scalability and avoid bad practices such as the use of global variables.
 Another problem I would like to discuss in this context is the lack of established tools for unit testing and code documentation in Fortran, which hampers progress during collaborative development.

description: We study the influence of an external magnetic field on the deconfinement transition in two-flavour lattice QCD with physical quark charges. We use dynamical overlap fermions without any approximation such as fixed topology and perform simulations on a $16^3 \times 6$ lattice and at a pion mass around $500MeV$. The pion mass (as well as the lattice spacing) was determined in independent runs on $12^3 \times 24$ lattices. We consider two temperatures, one of which is close to the deconfinement transition and one which is above. Within our limited statistics the dependence of the Polyakov loop and chiral condensate on the magnetic field supports the "inverse magnetic catalysis" scenario in which the transition temperature decreases as the field strength grows for temperature not to far above the critical temperature.

description: We introduce a dependent Bayesian nonparametric model for the probabilistic modeling of membership of subgroups in a community based on partially replicated data. The focus here is on species-by-site data, i.e. community data where observations at different sites are classified in distinct species. Our aim is to study the impact of additional covariates, for instance environmental variables, on the data structure, and in particular on the community diversity. To that purpose, we introduce dependence a priori across the covariates, and show that it improves posterior inference. We use a dependent version of the Griffiths-Engen-McCloskey distribution defined via the stick-breaking construction. This distribution is obtained by transforming a Gaussian process whose covariance function controls the desired dependence. The resulting posterior distribution is sampled by Markov chain Monte Carlo. We illustrate the application of our model to a soil microbial dataset acquired across a hydrocarbon contamination gradient at the site of a fuel spill in Antarctica. This method allows for inference on a number of quantities of interest in ecotoxicology, such as diversity or effective concentrations, and is broadly applicable to the general problem of communities response to environmental variables.

description: Registering point clouds of forest environments is an essential prerequisite for LiDAR applications in precision forestry. State-of-the-art methods for forest point cloud registration require the extraction of individual tree attributes, and they have an efficiency bottleneck when dealing with point clouds of real-world forests with dense trees. We propose an automatic, robust, and efficient method for the registration of forest point clouds. Our approach first locates tree stems from raw point clouds and then matches the stems based on their relative spatial relationship to determine the registration transformation. The algorithm requires no extra individual tree attributes and has quadratic complexity to the number of trees in the environment, allowing it to align point clouds of large forest environments. Extensive experiments on forest terrestrial point clouds have revealed that our method inherits the effectiveness and robustness of the stem-based registration strategy while exceedingly increasing its efficiency. Besides, we introduce a new benchmark dataset that complements the very few existing open datasets for the development and evaluation of registration methods for forest point clouds. The source code of our method and the dataset are available at https://github.com/zexinyang/GlobalMatch.

We analyze the effects of the pull-back by diffeomorphisms on pseudodifferential operators. We restrict to diffeomorphisms that preserve the filtration and prove that they are Pansu differentiable. We show that the pull-back of a semi-classical pseudodifferential operator by such a diffeomorphism has a semi-classical symbol that is expressed at leading order in terms of the Pansu differential. We interpret the geometric meaning of this invariance in the setting of filtered manifolds.

These diagrams produce an operator model on a Fock space suitable for representing any two-faced family of non-commutative random variables. Furthermore, using a Kreweras complement on bi-non-crossing partitions we establish the expected formulas for the multiplicative convolution of a bi-free pair of two-faced families.

description: Emerging heterogeneous wireless architectures consist of a dense deployment of local-coverage wireless access points (APs) with high data rates, along with sparsely-distributed, large-coverage macro-cell base stations (BS). We design a coded caching-and-delivery scheme for such architectures that equips APs with storage, enabling content pre-fetching prior to knowing user demands. Users requesting content are served by connecting to local APs with cached content, as well as by listening to a BS broadcast transmission. For any given content popularity profile, the goal is to design the caching-and-delivery scheme so as to optimally trade off the transmission cost at the BS against the storage cost at the APs and the user cost of connecting to multiple APs. We design a coded caching scheme for non-uniform content popularity that dynamically allocates user access to APs based on requested content. We demonstrate the approximate optimality of our scheme with respect to information-theoretic bounds. We numerically evaluate it on a YouTube dataset and quantify the trade-off between transmission rate, storage, and access cost. Our numerical results also suggest the intriguing possibility that, to gain most of the benefits of coded caching, it suffices to divide the content into a small number of popularity classes.

description: Recent studies have developed fundamental limitations on nanoscale thermodynamics, in terms of a set of independent free energy relations. Here we show that free energy relations cannot properly describe quantum coherence in thermodynamic processes. By casting time-asymmetry as a quantifiable, fundamental resource of a quantum state we arrive at an additional, independent set of thermodynamic constraints that naturally extend the existing ones. These asymmetry relations reveal that the traditional Szilard engine argument does not extend automatically to quantum coherences, but instead only relational coherences in a multipartite scenario can contribute to thermodynamic work. We find that coherence transformations are always irreversible. Our results also reveal additional structural parallels between thermodynamics and the theory of entanglement.

Year: 1968

description: Abstract:
The purpose of this study was to develop adequate guidelines whereby those interested in flood control planning would be able to apply a pair of digital computer programs known as the University of Kentucky Flood Control Planning Programs to ease the computational burden of evaluating specific flood control situations. Program II determines the economically optimum combination of channel improvement, land use restriction, and flood proofing for flood damage abatement. Program III also incorporates reservoir storage into the planning process. The Programs are not intended to provide a finished design but rather to select the optimum combination of flood control measures and residual flooding with regard to both time and space.
Application of Computer Programs to flood control planning is guided by presenting first a general description of the application process then a detailed description of the input required and the output produced by the Planning Programs. Input was developed and results interpreted to determine the optimum flood control plan for the upper reaches of the North Fork of the Kentucky River near Hazard, Kentucky.

description: While the use of semantic models has been explored in different areas of the Architecture, Engineering and Construction (AEC) industry to map and formalize knowledge and support different tasks, building renovation seems to be a neglected area in this field. Therefore, this paper presents the Renovation-Installation (Reno-Inst) ontology, which maps knowledge from the renovation domain considering different requirements, constraints, and other elements related to the installation of common renovation products such as windows, thermal insulation panels, and heat radiators. The development of the Reno-Inst ontology relies on an approach combining input from experts and knowledge from related engineering documents. The verification and validation process includes a content evaluation workshop with experts, a verification design stage, and the analysis and implementation of a real case study. The paper provides another example of the power of ontologies as a method for mapping and representing knowledge, gathering, and retrieving relevant information. Particularly, renovation projects encounter diverse challenges that lead to cost and schedule overruns, making their performance typically low. Therefore, the proposed Reno-Inst ontology provides a basis from which new applications can be developed, tested, and deployed to support improvements in the building renovation field, especially in the planning and execution of renovation activities.
Topological defects as lagrangian correspondences

description: Topological defects attract much recent interest in high-energy and condensed matter physics because they encode (non-invertible) symmetries and dualities. We study codimension-1 topological defects from a hamiltonian point of view, with the defect location playing the role of `time'. We show that the Weinstein symplectic category governs topological defects and their fusion: each defect is a lagrangian correspondence, and defect fusion is their geometric composition. We illustrate the utility of these ideas by constructing S- and T-duality defects in string theory, including a novel topology-changing non-abelian T-duality defect.

description: The linearized stability of stationary solutions for surface diffusion is studied. We consider hypersurfaces that lie inside a fixed domain, touch its boundary with a right angle and fulfill a no-flux condition. We formulate the geometric evolution law as a partial differential equation with the help of a parametrization from Vogel [Vog00], which takes care of a possible curved boundary. For the linearized stability analysis we identify as in the work of Garcke, Ito and Kohsaka [GIK05] the problem as an H

description: We calculate the kaon semileptonic form factor $f_+(0)$ from lattice QCD, working, for the first time, at the physical light-quark masses. We use gauge configurations generated by the MILC collaboration with $N_f=2+1+1$ flavors of sea quarks, which incorporate the effects of dynamical charm quarks as well as those of up, down, and strange. We employ data at three lattice spacings to extrapolate to the continuum limit. Our result, $f_+(0) = 0.9704(32)$, where the error is the total statistical plus systematic uncertainty added in quadrature, is the most precise determination to date. Combining our result with the latest experimental measurements of $K$ semileptonic decays, one obtains the Cabibbo-Kobayashi-Maskawa matrix element $|V_{us}|=0.22290(74)(52)$, where the first error is from $f_+(0)$ and the second one is from experiment. In the first-row test of Cabibbo-Kobayashi-Maskawa unitarity, the error stemming from $|V_{us}|$ is now comparable to that from $|V_{ud}|$.

Non-archimedean Yomdin-Gromov parametrizations and points of bounded height

description: We prove an analogue of the Yomdin-Gromov Lemma for $p$-adic definable sets and more broadly in a non-archimedean, definable context. This analogue keeps track of piecewise approximation by Taylor polynomials, a nontrivial aspect in the totally disconnected case. We apply this result to bound the number of rational points of bounded height on the transcendental part of $p$-adic subanalytic sets, and to bound the dimension of the set of complex polynomials of bounded degree lying on an algebraic variety defined over $\mathbb{C} ((t))$, in analogy to results by Pila and Wilkie, resp. by Bombieri and Pila. Along the way we prove, for definable functions in a general context of non-archimedean geometry, that local Lipschitz continuity implies piecewise global Lipschitz continuity.

Spin-dependent beating patterns in thermoelectric properties: Filtering the carriers of the heat flux in a Kondo adatom system

description: We theoretically investigate the thermoelectric properties of a spin-polarized two-dimensional electron gas hosting a Kondo adatom hybridized with an STM tip. Such a setup is treated within the single-impurity Anderson model in combination with the atomic approach for the Green's functions. Due to the spin dependence of the Fermi wavenumbers the electrical and thermal conductances, together with thermopower and Lorenz number reveal beating patterns as function of the STM tip position in the Kondo regime. In particular, by tuning the lateral displacement of the tip with respect to the adatom vicinity, the temperature and the position of the adatom level, one can change the sign of the Seebeck coefficient through charge and spin. This opens a possibility of the microscopic control of the heat flux analogously to that established for the electrical current.
