title: Assessing social and emotional difficulties of children in residential care settings : a systematic review of strengths-based measures
Creators: name: Day, Danielle

description: The number of children in residential care in England has increased over recent years. Studies have shown that these children often have poorer emotional wellbeing and social outcomes compared to their peers. It is therefore crucial that the care these children receive is informed by the child’s own needs. Strengths-based measures seek to use a collaborative approach to assess a young person's areas of strength, and to use these to help the young person during times of adversity. The current research sought to systematically review existing strengths-based measures used in residential care settings. Results showed that there were four measures in total, including strengths-based questions. Psychometrics and the usability of these measures are discussed.

description: Ingestion of inorganic arsenic through food and water can have severe adverse health effects on the human body. Therefore, government regulations and health guidelines for arsenic concentrations in water have been established around the world to avoid or mitigate these health effects. In recent decades, analysis of groundwater in many locations around the world have revealed arsenic concentrations that exceed government regulation levels. The section of the Carolina Terrane located in North Carolina is one of such recently discovered areas. This study investigates the relationship between the geologic units of the Carolina terrane and arsenic concentrations in well water samples in Orange County, North Carolina. Kriging interpolation mapping and multivariate analysis reveals spatial and geochemical connections between wells of detectable arsenic and the Neoproterozoic epiclastics unit and geochemical variables such as F−, pH, and alkalinity. These associations imply that arsenic in Orange County, NC is being mobilized from authigenic arsenic-bearing sulfide minerals in the Neoproterozoic epiclastics bedrock unit by oxidative release likely associated with increased F−, pH, and alkalinity.

title: Competitive analysis of the online dial-a-ride problem
Creators: name: Birx, Alexander
Publisher: name: UNSPECIFIED
Year: 2020

description: Online optimization, in contrast to classical optimization, deals with optimization problems whose input data is not immediately available, but instead is revealed piece by piece. An online algorithm has to make irrevocable optimization decisions based on the arriving pieces of data to compute a solution of the online problem. The quality of an online algorithm is measured by the competitive ratio, which is the quotient of the solution computed by the online algorithm and the optimum offline solution, i.e., the solution computed by an optimum algorithm that has knowledge about all data from the start. In this thesis we examine the online optimization problem online Dial-a-Ride. This problem consists of a server starting at a distinct point of a metric space, called origin, and serving transportation requests that appear over time. The goal is to minimize the makespan, i.e., to complete serving all requests as fast as possible. We distinguish between a closed version, where the server is required to return to the origin, and an open version, where the server is allowed to stay at the destination of the last served request. In this thesis, we provide new lower bounds for the competitive ratio of online Dial-a-Ride on the real line for both the open and the closed version by expanding upon the approach of Bjelde et al.'s work. In the case of the open version, the improved lower bound separates online Dial-a-Ride from its special case online TSP, where starting position and destination of requests coincide. To produce improved upper bounds for the competitive ratio of online Dial-a-Ride, we generalize the design of the Ignore algorithm and the Smartstart algorithm into the class of schedule-based algorithms. We show lower bounds for the competitive ratios of algorithms of this class and then provide a thorough analysis of Ignore and Smartstart. Identifying and correcting a critical weakness of Smartstart gives us the improved Smarterstart algorithm. This schedule-based algorithm attains the best known upper bound for open online Dial-a-Ride on the real line as well as on arbitrary metric spaces. Finally, we provide an analysis of the Replan algorithm improving several known bounds for the algorithm's competitive ratio.

description: Qualitative audio diary methods are an effective tool to explore emotions in social research as the method helps to elucidate diverse and sequential emotional experiences. Diary methods provide opportunities for research to be conducted over time in hard-to-reach settings, with hard-to-reach groups, producing rich data on sensitive topics. However, diary methods also provide ethical challenges, especially for novice researchers. Residential childcare practitioners are an important workforce that support looked after children and young people in residential children's homes, and this article reflects on the initial ethical challenges of using an audio diary method to study their emotional experiences. By exploring the ethical processes of minimising harm in a diary study with practitioners this article informs future diary research and highlights the potential use of audio diaries in future residential childcare practice.

description: We present a novel method for recovering world-grounded human motion from monocular video. The main challenge lies in the ambiguity of defining the world coordinate system, which varies between sequences. Previous approaches attempt to alleviate this issue by predicting relative motion in an autoregressive manner, but are prone to accumulating errors. Instead, we propose estimating human poses in a novel Gravity-View (GV) coordinate system, which is defined by the world gravity and the camera view direction. The proposed GV system is naturally gravity-aligned and uniquely defined for each video frame, largely reducing the ambiguity of learning image-pose mapping. The estimated poses can be transformed back to the world coordinate system using camera rotations, forming a global motion sequence. Additionally, the per-frame estimation avoids error accumulation in the autoregressive methods. Experiments on in-the-wild benchmarks demonstrate that our method recovers more realistic motion in both the camera space and world-grounded settings, outperforming state-of-the-art methods in both accuracy and speed.

Year: 2022

description: In this paper, we aim to explore some of the notions and concepts around 'emerging adulthood'; what this might mean for Scotland's care experienced young people; and what this might mean for those who care for them. Societally, transition to adulthood is a longer, more extended process than it was a few decades ago. Young people now generally live longer with their parents who tend to help with ongoing practical and financial support, as well as providing ongoing emotional and relational support and security. Changes in access to secure well-paid employment and to affordable housing and accommodation have been cited as key influencing factors. However, despite recent changes in domestic policy and legislation, too many young people growing up in alternative care – in foster care, residential care and kinship care – continue to experience their transitions from care to adulthood to be accelerated and abrupt. We set the context by exploring some definitions and offering some reflections on the concept of emerging adulthood, and what this might mean for young people transitioning from care to adulthood and interdependence. The challenges faced by our young people, and the need for extended care has become even more amplified as the impacts of the COVID-19 pandemic have hit home - and as the fragility of supports, and the structural disadvantages that many care experienced young people face, have been laid bare.
A bioavailable strontium isoscape for Western Europe: A machine learning approach

description: Strontium isotope ratios (87Sr/86Sr) are gaining considerable interest as a geolocation tool and are now widely applied in archaeology, ecology, and forensic research. However, their application for provenance requires the development of baseline models predicting surficial 87Sr/86Sr variations (“isoscapes”). A variety of empirically-based and process-based models have been proposed to build terrestrial 87Sr/86Sr isoscapes but, in their current forms, those models are not mature enough to be integrated with continuous-probability surface models used in geographic assignment. In this study, we aim to overcome those limitations and to predict 87Sr/86Sr variations across Western Europe by combining process-based models and a series of remote-sensing geospatial products into a regression framework. We find that random forest regression significantly outperforms other commonly used regression and interpolation methods, and efficiently predicts the multi-scale patterning of 87Sr/86Sr variations by accounting for geological, geomorphological and atmospheric controls. Random forest regression also provides an easily interpretable and flexible framework to integrate different types of environmental auxiliary variables required to model the multi-scale patterning of 87Sr/86Sr variability. The method is transferable to different scales and resolutions and can be applied to the large collection of geospatial data available at local and global levels. The isoscape generated in this study provides the most accurate 87Sr/86Sr predictions in bioavailable strontium for Western Europe (R2 = 0.58 and RMSE = 0.0023) to date, as well as a conservative estimate of spatial uncertainty by applying quantile regression forest. We anticipate that the method presented in this study combined with the growing numbers of bioavailable 87Sr/86Sr data and satellite geospatial products will extend the applicability of the 87Sr/86Sr geo-profiling tool in provenance applications.

SCDEW models assume a strong coupling between Dark Energy (DE) and an ancillary Cold Dark Matter (CDM) component together with the presence of an uncoupled Warm Dark Matter component. The strong coupling between CDM and DE allows us to preserve small scale fluctuations even if the warm particle is quite light ($\approx 100$ eV). Our large scale simulations show that, for $10^{11}

description: The Neoproterozoic Hüttenberg Formation in northeastern Namibia records a remarkable δ13Ccarb positive excursion with a sustained plateau of values up to +12‰ (i.e., the Hüttenberg anomaly). High-resolution chemostratigraphic analyses of drill core samples spanning the upper Elandshoek and Hüttenberg formations reveal multiple new observations: (1) overall high but oscillatory δ13Ccarb values; (2) δ18Ocarb values ranging from −8‰ to −2‰; (3) significant enrichment of 13C in organic carbon and a broad co-variation between δ13Ccarb and δ13Corg; (4) a profound negative excursion in δ34Spyrite from +30‰ to −10‰; (5) an overall inverse δ13C–δ34S relationship; and (6) 87Sr/86Sr values down to 0.7074 in limestone samples. The new data suggest that the Hüttenberg anomaly records dynamic fluctuations in marine redox conditions, which may include an oxygenation event during the height of the δ13Ccarb positive excursion and a deoxygenation event at its termination. The δ34Spyrite negative excursion suggests the buildup of the marine sulfate reservoir, likely due to enhanced pyrite oxidation during the oxygenation event. The δ34Spyrite increase at the end of the Hüttenberg anomaly may result from a seawater sulfate concentration drawdown towards pre-anomaly conditions. On one hand, the Hüttenberg anomaly may reflect restricted basin signals that are deviated from the Ediacaran open ocean; on the other hand, the Ediacaran Hüttenberg anomaly, together with the Cryogenian δ13Ccarb positive excursions, suggests a stepwise pattern of the Neoproterozoic Oxygenation Event. Both local and global environmental factors may have contributed to the Hüttenberg anomaly. The Hüttenberg anomaly therefore represents a local enhancement of global oxygenation signals. Our data support the emerging view that the Neoproterozoic Oxygenation Event may have facilitated the evolution of early life at that time.

description: This paper presents a general framework for generating greedy algorithms for solving convex constraint satisfaction problems for sparse solutions by mapping the satisfaction problem into one of graph traversal on a rooted tree of unknown topology. For every pre-walk of the tree an initial set of generally dense feasible solutions is processed in such a way that the sparsity of each solution increases with each generation unveiled. The specific computation performed at any particular child node is shown to correspond to an embedding of a polytope into the polytope received from that nodes parent. Several issues related to pre-walk order selection, computational complexity and tractability, and the use of heuristic and/or side information is discussed. An example of a single-path, depth-first algorithm on a tree with randomized vertex reduction and a run-time path selection algorithm is presented in the context of sparse lowpass filter design.

description: Island arcs provide insights into the origin and recycling of continental crust, but questions remain concerning source metasomatism, the depth of differentiation, the potential role of amphibole fractionation, and the time scales involved. Basaltic andesites on Batan Island (Philippines) contain ≥ 150 Ma peridotite fragments encased in hornblendite and gabbroic rinds produced via melt-rock reaction. The peridotites have some of the lightest δ7Li and δ57Fe values yet measured in mantle rocks. These values are too fractionated to have been created solely by equilibrium partial melting and thus require a combination of melt depletion and slab fluid addition and may be derived from diffusion-modified melt channel wall rocks. Stable isotope signals are easily modified by diffusive equilibration between peridotite and host magma, so the preservation of light δ7Li and δ57Fe here suggests magma ascent rates of ~10 km yr-1. We show that melt-wall rock reactions at ~25-30 km depth led to the crystallization of amphibole (± plagioclase) followed by gabbroic fractionation at ~7 km depth. The former provides a location and mechanism for the "cryptic" amphibole fractionation observed in these and perhaps many other arc lavas and may obviate the requirement for delamination of cumulates.

description: BACKGROUND: Kidney transplant is the treatment of choice for patients with end-stage renal disease. Early detection of allograft injury is important to delay or prevent irreversible damage. PURPOSE: To investigate the feasibility of hyperpolarized (HP) [1-13C]pyruvate MRI for assessing kidney allograft metabolism. SUBJECTS: 6 participants (mean age, 45.2 +- 12.4 years, 2 females) scheduled for kidney allograft biopsy and 5 patients (mean age, 59.6 +- 10.4 years, 2 females) with renal cell carcinoma (RCC). ASSESSMENT: Five of the six kidney allograft participants underwent biopsy after MRI. Estimated glomerular filtration rate (eGFR) and urine protein-to-creatine ratio (uPCR) were collected within 4 weeks of MRI. Kidney metabolism was quantified from HP [1-13C]pyruvate MRI using the lactate-to-pyruvate ratio in allograft kidneys and non-tumor bearing kidneys from RCC patients. RESULTS: Biopsy was performed a mean of 9 days (range 5-19 days) after HP [1-13C]pyruvate MRI. Three biopsies were normal, one showed low-grade fibrosis and one showed moderate microvascular inflammation. All had stable functioning allografts with eGFR > 60 mL/min/1.73 m2 and normal uPCR. One participant who did not undergo biopsy had reduced eGFR of 49 mL/min/1.73 m2 and elevated uPCR. The mean lactate-to-pyruvate ratio was 0.373 in participants with normal findings (n = 3) and 0.552 in participants with abnormal findings (n = 2). The lactate-to-pyruvate ratio was highest (0.847) in the participant with reduced eGFR and elevated uPRC. Native non-tumor bearing kidneys had a mean lactate-to-pyruvate ratio of 0.309. DATA CONCLUSION: Stable allografts with normal findings at biopsy showed lactate-to-pyruvate ratios similar to native non-tumor bearing kidneys, whereas allografts with abnormal findings showed higher lactate-to-pyruvate ratios.

description: Embeddings of the Racah algebra into the Bannai-Ito algebra are proposed in two realizations. First, quadratic combinations of the Bannai-Ito algebra generators in their standard realization on the space of polynomials are seen to generate a central extension of the Racah algebra. The result is also seen to hold independently of the realization. Second, the relationship between the realizations of the Bannai-Ito and Racah algebras by the intermediate Casimir operators of the $\mathfrak{osp}(1|2)$ and $\mathfrak{su}(1,1)$ Racah problems is established. Equivalently, this gives an embedding of the invariance algebra of the generic superintegrable system on the two-sphere into the invariance algebra of its extension with reflections, which are respectively isomorphic to the Racah and Bannai-Ito algebras.

description: We report the formation of a non-magnetic band insulator at the isopolar interface between the antiferromagnetic Mott-Hubbard insulator LaTiO3 and the antiferromagnetic charge transfer insulator LaFeO3. By density functional theory calculations, we find that the formation of this interface state is driven by the combination of O band alignment and crystal field splitting energy of the t2g and eg bands. As a result of these two driving forces, the Fe 3d bands rearrange and electrons are transferred from Ti to Fe. This picture is supported by x-ray photoelectron spectroscopy, which confirms the rearrangement of the Fe 3d bands and reveals an unprecedented charge transfer up to 1.2+/-0.2 e-/interface unit cell in our LaTiO3/LaFeO3 heterostructures.

Based on a sign-problem-free quantum Monte Carlo approach, we access both the ferromagnetic and the ferroquadrupolar ordered, spin nematic phase as well as the SU(3)-symmetric point which separates these phases. Signatures of Goldstone soft-modes in the dynamical spin and the quadrupolar structure factors are identified, and the properties of the low-energy excitations are compared to the thermodynamic behavior observed at finite temperatures as well as to Schwinger-boson flavor-wave theory.

description: The broken symmetry that develops below 17.5K in the heavy fermion compound URu2Si2 has long eluded identification. Here we argue that the recent observation of Ising quasiparticles in URu2Si2 results from a spinor hybridization order parameter that breaks double time-reversal symmetry by mixing states of integer and half-integer spin. Such "hastatic order" (hasta:[Latin]spear) hybridizes Kramers conduction electrons with Ising, non-Kramers 5f2 states of the uranium atoms to produce Ising quasiparticles. The development of a spinorial hybridization at 17.5K accounts for both the large entropy of condensation and the magnetic anomaly observed in torque magnetometry. This paper develops the theory of hastatic order in detail, providing the mathematical development of its key concepts. Hastatic order predicts a tiny transverse moment in the conduction sea, a collosal Ising anisotropy in the nonlinear susceptibility anomaly and a resonant energy-dependent nematicity in the tunneling density of states.

We find a significant dependence of the properties of late-type brightest group galaxies on the large-scale environment: they show statistically significant higher luminosities and stellar masses, redder u-r colours, lower star formation activity and longer star-formation time-scale when embedded in superstructures. By contrast, the properties of the early-type brightest group galaxies are remarkably similar regardless of the group global environment. The other group member galaxies exhibit only the local influence of the group they inhabit. Our analysis comprises tests against the dependence on the host group luminosity and we argue that group brightest member properties are not only determined by the host halo, but also by the large-scale structure which can influence the accretion process onto their late-type brightest galaxies.

title: Continuum Systems in the No-Core Shell Model
Creators: name: Alexa, Stefan Vasco
Publisher: name: UNSPECIFIED

description: The progress of ab initio nuclear structure in the past two decades revealed the need to incorporate continuum degrees of freedom. They are indispensable in the treatment of nuclear structure and for connecting theory to experiments performed at the extremes of low-energy many-body scattering. Many-body continuum calculation are a challenging task. It makes sense to build on the proven ab initio bound-state methods, if possible. In this work, we present combinations of the ab initio nuclear structure method of the No-Core Shell Model (NCSM) with two approaches that give access to observables in the nuclear continuum. These methods are the Harmonic Oscillator Representation of Scattering Equations (HORSE) and the Analytic Continuation in the Coupling Constant (ACCC). The focus is on the determination of resonance parameters, which is motivated by the possible existence of a resonating four-neutron J = 0+ state, the tetraneutron, proposed by a recently conducted experiment. We employ various state-of-the-art Chiral Effective Field Theory (χEFT) interactions. We first introduce the HORSE method and its simplification, the Single-State HORSE, which belong to the so-called J-matrix methods. The J-matrix approach uses the tridiagonality of the kinetic energy in a specific basis representation to connect an interior, interacting region, to an exterior, free region. With the Single-State HORSE method, we calculate tetraneutron phase shifts derived in a hyperspherical framework. We use various Similarity Renormalization Group evolved χEFT interactions and two phenomenological potentials, studying their effects on phase shifts. The calculations are performed in large NCSM model spaces. The phase shifts are in line with the existence of a resonance, showing characteristic features of such states. We further show a way of obtaining a hyperspherical basis within the framework of the Jacobi-NCSM. This paves the way for future studies involving full HORSE Green's function. The second method used to investigate resonances, with an application to the dineutron and tetraneutron, is the ACCC. The method provides access to resonances on the complex k-plane by using the analytic properties of the Jost function as a function of a coupling constant. It relies solely on bound-state calculations by artificially binding the system to obtain energies at different coupling strengths, which are fitted by Pade approximants and extrapolated to the initial interaction strength. We show two different binding procedures, an additional four-body potential constructed on matrix element level from the smallest NCSM model spaces, dubbed eigenvector binding. This is motivated by the desire to avoid bound substructures. The second procedure is a straightforward multiplication of the interaction matrix elements by a factor. The dineutron results show that the binding methods do not falsely produce resonances. The tetraneutron results support a resonance in the case of eigenvector binding, but not so for the direct matrix element modification.

Strongly Coupled Dark Energy Cosmologies: preserving LCDM success and easing low scale problems I - Linear theory revisited

description: In this first paper we discuss the linear theory and the background evolution of a new class of models we dub SCDEW: Strongly Coupled DE, plus WDM. In these models, WDM dominates today's matter density; like baryons, WDM is uncoupled. Dark Energy is a scalar field $Φ$; its coupling to ancillary CDM, whose today's density is $\ll 1\, \%$, is an essential model feature. Such coupling, in fact, allows the formation of cosmic structures, in spite of very low WDM particle masses ($\sim 100$ eV). SCDEW models yields Cosmic Microwave Background and linear Large Scale features substantially undistinguishable from $Λ$CDM, but thanks to the very low WDM masses they strongly alleviate $Λ$CDM issues on small scales, as confirmed via numerical simulations in the II associated paper. Moreover SCDEW cosmologies significantly ease the coincidence and fine tuning problems of $Λ$CDM and, by using a field theory approach, we also outline possible links with inflationary models. We also discuss a possible fading of the coupling at low redshifts which prevents non linearities on the CDM component to cause computational problems. The (possible) low-$z$ coupling suppression, its mechanism, and its consequences are however still open questions -not necessarily problems- for SCDEW models. The coupling intensity and the WDM particle mass, although being extra parameters in respect to $Λ$CDM, are found to be substantially constrained a priori so that, if SCDEW is the underlying cosmology, we expect most data to fit also $Λ$CDM predictions.

description: Rare earth elements (REEs) signatures in the dissolved loads of rivers serve as excellent monitors of weathering processes within a basin. However, quantifying REE behavior spatially (along a river's profile) and temporally (seasonable variations) is rare. This investigation reports REE concentrations of dissolved river loads collected during four sampling seasons at five monitoring stations along the Neuse River, North Carolina. The areal percentage of the Neuse River's catchment lithology composition, Post Archean Australian Shale (PAAS) normalized REE patterns, inter-REE ratios, and calculated anomalous REE values (i.e. cerium anomaly, gadolinium anomaly) were determined at each site in four seasons over a year. Our results show slight differences among inter-REE relationships and anomalous REE values in the dissolved loads along the length of the river. PAAS normalized REE patterns of dissolved water loads vary slightly spatially and temporally among the five sampling stations, and experience varying values of anomalous REE values. Collected data indicates that both variations in localized REE patterns and local bedrock occur along the river profile. Significant gadolinium (Gd) anomalies varied seasonally and spatially at select sites, suggesting changes in REE behavior along a river result from both natural and anthropogenic processes.

description: We model the evolution of eukaryotic protein-protein interaction (PPI) networks. In our model, PPI networks evolve by two known biological mechanisms: (1) Gene duplication, which is followed by rapid diversification of duplicate interactions. (2) Neofunctionalization, in which a mutation leads to a new interaction with some other protein. Since many interactions are due to simple surface compatibility, we hypothesize there is an increased likelihood of interacting with other proteins in the target protein's neighborhood. We find good agreement of the model on 10 different network properties compared to high-confidence experimental PPI networks in yeast, fruit flies, and humans. Key findings are: (1) PPI networks evolve modular structures, with no need to invoke particular selection pressures. (2) Proteins in cells have on average about 6 degrees of separation, similar to some social networks, such as human-communication and actor networks. (3) Unlike social networks, which have a shrinking diameter (degree of maximum separation) over time, PPI networks are predicted to grow in diameter. (4) The model indicates that evolutionarily old proteins should have higher connectivities and be more centrally embedded in their networks. This suggests a way in which present-day proteomics data could provide insights into biological evolution.

description: The environmental impact of Three Gorges Dam (TGD) in the Changjiang (Yangtze River) is an important topic of concern for scientific communities and the public. However, the changes in river water chemistry in response to the dam construction remain poorly constrained. This study presents the seasonal variability of all major cations and some anions in the lower Changjiang during a full hydrological year from 2010 to 2011. The concentrations of all ions, except for HCO3 −, are higher after the TGD operation than before (p < 0.01), implying that the TGD has modified the river water chemistry in the mid-lower mainstream. Dissolved silicate (DSi) fluxes at Datong station thus increase slightly since the beginning of TGD impoundment. The change of mixing pattern of different water sources and alteration of hydrological and biogeochemical processes could cause the change of solute concentrations in the mid-lower Changjiang after the TGD operation. The mass balance model suggests that two factors primarily account for this increase of DSi observed at Datong: 1) an increasing loading of DSi downstream TGD due to erosion by “clean water”, and 2) an enhanced “Source” role of Lake Poyang in the mid-lower reaches. Our study would provide insights into the damming effect on river water chemistry and the complexity of a large river system facing rapid climate change and strong human activities.

description: We review basic physics and novel types of optical angular momentum. We start with a theoretical overview of momentum and angular momentum properties of generic optical fields, and discuss methods for their experimental measurements. In particular, we describe the well-known longitudinal (i.e., aligned with the mean momentum) spin and orbital angular momenta in polarized vortex beams. Then, we focus on the transverse (i.e., orthogonal to the mean momentum) spin and orbital angular momenta, which were recently actively discussed in theory and observed in experiments. First, the recently-discovered transverse spin angular momenta appear in various structured fields: evanescent waves, interference fields, and focused beams. We show that there are several kinds of transverse spin angular momentum, which differ strongly in their origins and physical properties. We describe extraordinary features of the transverse optical spins and overview recent experiments. In particular, the helicity-independent transverse spin inherent in edge evanescent waves offers robust spin-direction coupling at optical interfaces (the quantum spin Hall effect of light). Second, we overview the transverse orbital angular momenta of light, which can be both extrinsic and intrinsic. These two types of the transverse orbital angular momentum are produced by spatial shifts of the optical beams (e.g., in the spin Hall effect of light) and their Lorentz boosts, respectively. Our review is underpinned by a unified theory of the angular momentum of light based on the canonical momentum and spin densities, which avoids complications associated with the separation of spin and orbital angular momenta in the Poynting picture. It allows us to construct comprehensive classification of all known optical angular momenta based on their key parameters and main physical properties.
