description: Aims: This study examines the effects of recent changes in Medicare long-term care hospital (LTCH) payments on treatment patterns and outcomes for severe wound patients discharged from short-term acute care hospitals (STACHs). Materials and methods: The rolling implementation of a new Medicare payment policy was used to develop a difference-in-difference model. The study population consisted of Medicare beneficiaries subjected to the payment policy changes and hospitalized for stage 3, 4, or unstageable wounds; non-healing surgical wounds; and fistula. Using 2015-Q1-2017 Medicare claims data, changes in outcomes were examined for severe wound patients exposed to the new policy (treatment) and those that were not (comparison). All outcomes were modeled using linear regressions and adjusted for patient clinical characteristics. Analysis was conducted in a full sample and a sample with high-LTCH-use propensity. Results: Severe wound patients exposed to the new policy experienced 4.1 and 7.5 percentage point (pp) reductions in LTCH use relative to the comparison group in the full sample and high-LTCH-propensity sample, respectively (p p = .039). No statistically significant change was found in 60-day mortality or Medicare spending after the policy change in the treatment group as compared to the comparison group (p > .10). However, among severe wound patients who are exposed to the new policy in the high-LTCH-propensity sample, readmission and post-discharge sepsis rates increased after the policy change relative to the comparison group (readmission rate = 8.1 pp, p = .075; sepsis rate = 7.0 pp, p = .033). Limitations: The findings are based on data from a limited timeframe around the policy change and, thus, provide only early evidence on the effects of the new policy. Conclusion: The new LTCH payment policy is associated with no changes in Medicare spending and mortality, but higher readmissions and post-discharge sepsis rates among severe wound patients with a high likelihood to use an LTCH.

description: Non-compact QED(3) with four-component fermion flavor content larger than or equal to two is studied numerically near the chiral limit to understand its chiral symmetry breaking features. We monitor discretization and finite size effects on the chiral condensate by simulating the model at different values of the gauge coupling on lattices ranging in size from 10^3 to 50^3. Our upper bound for the dimensionless condensate beta^2 in the N_f=2 case is 5x10^{-5}.

description: The basic services offered by country elevators are very similar (purchasing, conditioning and storing grain), country elevators attempt to differentiate themselves from their competition by offering customers a variety of cash grain marketing tools. These tools range from the basic cash forward contracts to minimum price contracts to the so called “new generation grain marketing contracts”. The purpose of this paper is to report the results of a 2010 survey of Illinois country grain elevator managers. The primary objective of the survey was to determine the marketing contracts grain elevator firms operating in Illinois offer their customers and the extent to which these contracts are used by the elevator’s customers.
Ligand-specific regulation and signalling by the neuromedin U 2 receptor

description: Neuromedin U receptor 2 (NMU2) is a Family A, G protein-coupled receptor (GPCR) for both neuromedin U (NmU) and neuromedin S (NmS), particularly within the CNS where effects include the suppression of feeding behaviour and increased energy expenditure suggesting an anti-obesity target. Although NMU2 preferentially activates Gαq/11, it is unclear which signalling underlies physiological outcomes or if the ligands generate different responses. Here, NMU2 signalling and regulation have been explored, including using a protocol of brief ligand exposure to match exposure patterns of peptidergic receptors in vivo.In HEK293 cells stably expressing human (h) NMU2, hNmU-25 and hNmS-33 evoked similar Ca2+ signalling, although resensitisation required only 6 h following brief (5 min) exposure to hNmU-25 but more than 6 h following hNmS-33. Activation of the mitogen-activated protein kinases (MAPKs) ERK, P38 and JNK, was more sustained following brief exposure to hNmS-33 compared to hNmU-25. NMU2 phosphorylation was increased by both ligands and inhibition of protein kinase C (PKC) reduced this by ~50%. Phosphorylation was more sustained following brief exposure to hNmS-33 than hNmU-25. Sustained challenge with either ligand sustained the recruitment of arrestin 2 and 3 to NMU2. Ligand removal resulted in loss of arrestin interaction that was slower for arrestin 2 but similar for the two ligands. This suggests that following brief exposure to hNmS-33, sustained NMU2 phosphorylation does not sustain arrestin recruitment and arrestin recruitment is not responsible for sustained MAPK activation. Five phosphorylated serine or threonine residues were identified in the C-terminus of NMU2 by mass spectrometry. Mutation of these reduced phosphorylation by both ligands and phosphorylation was abolished by PKC inhibition. Mutation of seven other serine/threonine residues reduced phosphorylation by hNmU-25 more than hNmS-33, suggesting different phosphorylation patterns. Mutation of all fourteen C-terminal serine/threonine residues abolished agonist-dependent phosphorylation. These data highlight ligand-dependent NMU2 signalling and regulation, particularly following brief ligand exposure. Such ligand dependence may be relevant to other GPCRs but their consequence to physiology and implications for drug discovery require further study.

description: Observations suggest that some massive stars experience violent and eruptive mass loss associated with significant brightening that cannot be explained by hydrostatic stellar models. This event seemingly forms dense circumstellar matter (CSM). The mechanism of eruptive mass loss has not been fully explained. We focus on the fact that the timescale of nuclear burning gets shorter than the dynamical timescale of the envelope a few years before core collapse for some massive stars. To reveal the properties of the eruptive mass loss, we investigate its relation to the energy injection at the bottom of the envelope supplied by nuclear burning taking place inside the core. In this study, we do not specify the actual mechanism for transporting energy from the site of nuclear burning to the bottom of the envelope. Instead, we parameterize the amount of injected energy and the injection time and try to extract information on these parameters from comparisons with observations. We carried out 1-D radiation hydrodynamical simulations for progenitors of red, yellow, and blue supergiants, and Wolf-Rayet stars. We calculated the evolution of the progenitors with a public stellar evolution code. We obtain the light curve associated with the eruption, the amount of ejected mass, and the CSM distribution at the time of core-collapse. The energy injection at the bottom of the envelope of a massive star within a period shorter than the dynamical timescale of the envelope could reproduce some observed optical outbursts prior to the core-collapse and form the CSM, which can power an interaction supernova (SN) classified as type IIn.

description: We consider deeply inelastic scattering at very high energies in the saturation regime. The emerging picture corresponds to the propagation of a dipole, the quark-antiquark pair, in a shock wave color field of the target. We use the fomalism of Wilson lines to study the evolution of dipole densities in energy logarithms. Our analysis results into an equation in multicolor limit which sums leading logs but keeps the nonlinearities up to cubic order in densities.

Manipulating the Growth of Nanomaterials in Superfluid Helium Droplets: Formation of Hybrid Nanostructures and Nanoparticle Assemblies

description: This project intends to develop a technique to fabricate nanomaterials by manipulating the growth process using superfluid helium droplets as nanoreactors, which provide a cold and confined environment where atomic or molecular dopants can aggregate into clusters and even nanoparticles. A mass spectrometric study has been used to study binary molecular clusters containing a noble metal atom and an organic compound formed in helium droplets. The co-addition of metal has been found to influence the fragmentation patterns of the organic molecules depending on the relative ionisation energies of the selected molecules and metals. Nanoparticles with different sizes and forms have been fabricated by controlling the growth conditions such as the droplet source expansion and the pickup conditions. Direct growth of nanoparticle assemblies has been demonstrated for the first time as a novel bottom-up technique for nanoparticle synthesis. The direct growth technique is based on a templated growth of nanoparticle assembly in superfluid helium droplets, in which the nanoparticle grows directly at the binding sites in a molecular template. By using this technique, we have demonstrated the feasibility to grow nanoparticle with a high degree of control on both size and the interparticle distances. Besides, semiconductor CdS and core-shell of metal/CdS in the form of nanoparticles and nanowires were also prepared by the sequential doping of metal and CdS to the helium droplets. The nanoparticles and nanowires were grown by using different nozzle positions and nozzle temperatures. The nanowires formation was due to the presence of quantised vortices inside large helium droplets. A further study on the quantised vortices shows different patterns observed from different parts of the expansion region, which reflects the different rotational behaviour of the helium droplets. Images collected from the offset nozzle position provide the first evidence for the presence of multiply quantised vortices (rotational quanta > 1) in helium droplets, where small particles are seen at the vicinity of the chains of large particles.

description: Agricultural conservation easements have been traditionally used to transfer or extinguish development rights on farm and ranch land in order to preserve open space and conservation and natural resources. These transfers are typically made with governmental agencies or Internal Revenue Service qualified land trusts. Usually this process is initiated because the property owner wants to ensure future agricultural use as well as conserve natural resources in exchange for financial benefits in either payments and/or tax credits.

description: In recent years, the softmax model and its fast approximations have become the de-facto loss functions for deep neural networks when dealing with multi-class prediction. This loss has been extended to language modeling and recommendation, two fields that fall into the framework of learning from Positive and Unlabeled data. In this paper, we stress the different drawbacks of the current family of softmax losses and sampling schemes when applied in a Positive and Unlabeled learning setup. We propose both a Relaxed Softmax loss (RS) and a new negative sampling scheme based on Boltzmann formulation. We show that the new training objective is better suited for the tasks of density estimation, item similarity and next-event prediction by driving uplifts in performance on textual and recommendation datasets against classical softmax.

With the expansion ofthe U.S. ethanol industry in the form of both new and expandingplants both types of growth should be taken into account. This research estimates local economic impacts from an expanding ethanol plant as an example of what local impacts can be expected from the on-going growth in the U.S. ethanol industry. The results can have important ramifications for local businesses, grain producers, and property values.

description: Local deformations in medical modalities are common phenomena due to a multitude of factors such as metallic implants or limited field of views in magnetic resonance imaging (MRI). Completion of the missing or distorted regions is of special interest for automatic image analysis frameworks to enhance post-processing tasks such as segmentation or classification. In this work, we propose a new generative framework for medical image inpainting, titled ipA-MedGAN. It bypasses the limitations of previous frameworks by enabling inpainting of arbitrary shaped regions without a prior localization of the regions of interest. Thorough qualitative and quantitative comparisons with other inpainting and translational approaches have illustrated the superior performance of the proposed framework for the task of brain MR inpainting.

description: The cores of active galactic nuclei (AGNs) have been suggested as the sources of IceCube neutrinos, and recent numerical simulations have indicated that hot AGN coronae of Seyfert galaxies and radiatively inefficient accretion flows (RIAFs) of low-luminosity AGNs (LLAGNs) may be promising sites of ion acceleration. We present detailed studies on detection prospects of high-energy multi-messenger emissions from RIAFs in nearby LLAGNs. We construct a model of RIAFs that can reproduce the observational features of the current X-ray observations of nearby LLAGNs. We then calculate the high-energy particle emissions from nearby individual LLAGNs, including MeV gamma rays from thermal electrons, TeV--PeV neutrinos produced by non-thermal protons, and sub-GeV to sub-TeV gamma rays from proton-induced electromagnetic cascades. We find that, although these are beyond the reach of current facilities, proposed future experiments such as e-ASTROGAM and IceCube-Gen2 should be able to detect the MeV gamma rays and the neutrinos, respectively, or else they can place meaningful constraints on the parameter space of the model. On the other hand, the detection of high-energy gamma rays due to the electromagnetic cascades will be challenging with the current and near-future experiments, such as Fermi and Cherenkov Telescope Array. In an accompanying paper, we demonstrate that LLAGNs can be a source of the diffuse soft gamma-ray and TeV--PeV neutrino backgrounds, whereas in the present paper, we focus on the prospects for multi-messenger tests which can be applied to reveal the nature of the high-energy neutrinos and photons from LLAGNs.

description: When seasonal foreign farm workers with illegal resident status have left the country, farms experience difficulty in finding “motivated” equally efficient workers to fill in the void. This study’s survey and case study indicate that larger conventional farms usually opt for greater mechanization of their operations, with downsizing as another remedy. These farms also rely heavily on family members’ increased involvement in farm management. Enterprise budget analysis results suggest that when family farm labor inputs are exhausted, business losses could be realized, as yields are significantly reduced due to difficulty or delay in hiring domestic unskilled workers.

20th century poetry

description: Zbigniew Herbert, one of the most important Polish poets of the 20th century, decided to make his literary debut, titled “String of Light”, very late in his life – only at the age of 32, in 1956. This was facilitated not only by the temporarily improved political and cultural situation in post-war Poland, but also by his willingness to talk about the experience of war, which permanently shaped the author and his entire generation. In the collection, Herbert looks back at the injustice suffered, yet he does not try to forget it. Instead, he records it and applies an “antiquity filter”, connecting the recent war trauma with the universal human experience of conflict and suffering.

In this paper, I will analyze how Herbert expressed his experiences to process his war trauma. I will discuss selected excerpts from the poems belonging to the collection in terms of the following aspects related to the processing of trauma: the search for lost harmony, the emotions, the critical evaluation of the distant and nearer past, and the attempt to understanding the cruelty.

As an application, we describe all minimizers of the isoperimetric profile for volumes greater than the volume of the minimal Cheeger set, relative to a Jordan domain $Ω$ which has no necks of radius $r$, for all $r$. Finally, we show that for such sets and volumes the isoperimetric profile is convex.

description: Electronic and/or vibronic coherence has been found by recent ultrafast spectroscopy experiments in many chemical, biological and material systems. This indicates that there are strong and complicated interactions between electronic states and vibration modes in realistic chemical systems. Therefore, simulations of quantum dynamics with a large number of electronic and vibrational degrees of freedom are highly desirable. Due to the efficient compression and localized representation of quantum states in the matrix-product state (MPS) formulation, time-evolution methods based on the MPS framework, which we summarily refer to as tDMRG (time-dependent density-matrix renormalization group) methods, are considered to be promising candidates to study the quantum dynamics of realistic chemical systems. In this work, we benchmark the performances of four different tDMRG methods, including global Taylor, global Krylov, local one-site and two-site time-dependent variational principle (1TDVP and 2TDVP), with a comparison to multi-configuration time-dependent Hartree (MCTDH) and experimental results. Two typical chemical systems of internal conversion and singlet fission are investigated, one containing strong and high-order local and non-local electron-vibration couplings, the other exhibiting a continuous phonon bath. The comparison shows that the tDMRG methods (particularly, the 2TDVP method) can describe the full quantum dynamics in large chemical systems accurately and efficiently. Several key parameters in the tDMRG calculation including the truncation error threshold, time interval and ordering of local sites were also investigated to strike the balance between efficiency and accuracy of results.

description: We study the transmission of supersymmetry breaking via gravitational interactions in a five-dimensional brane-world compactified on $S^1/Z_2$. We assume that chiral matter and gauge fields are confined at the orbifold fixed points, where supersymmetry is spontaneously broken by effective brane superpotentials. Using an off-shell supergravity multiplet we integrate out the auxiliary fields and examine the couplings between the bulk supergravity fields and boundary matter fields. The corresponding tree-level shift in the bulk gravitino mass spectrum induces one-loop radiative masses for the boundary fields. We calculate the boundary gaugino and scalar masses for arbitrary values of the brane superpotentials, and show that the mass spectrum reduces to the Scherk-Schwarz limit for arbitrarily large values of the brane superpotentials.

An axially-symmetric three-dimensional jellium model, taking into account the effects due to the first Na monolayer and the Cu substrate, has been developed. The electronic structure is solved within the local-density approximation of the density-functional theory using a real-space multigrid method. The model enables the study of systems consisting of thousands of Na-atoms. The results for the local density of states are compared with differential conductance ($dI/dV$) spectra and constant current topographs from Scanning Tunneling Microscopy.

These corrections depend on the masses of charged Higgs boson and lighter stop, and the parameters $\tanβ$ and $μ$. For favorable parameter values, the corrections decrease or increase the decay widths significantly. Especially for high values of $\tanβ$(=30) the corrections exceed at least 10% for both $\tilde b_1$ and $\tilde b_2$ decay. But for low values of $\tanβ$(=4,10) the corrections are small and the magnitudes are less than 10%. The numerical calculations also show that using the running bottom quark mass which includes the QCD effects and resums all high order $\tanβ$-enhanced effects can improve much the convergence of the perturbation expansion.

description: We have experimentally implemented remote state preparation (RSP) of a qubit from a hydrogen to a carbon nucleus in molecules of carbon-13 labeled chloroform $^{13}$CHCl$_{3}$ over interatomic distances using liquid-state nuclear magnetic resonance (NMR) technique. Full RSP of a special ensemble of qubits, i.e., a qubit chosen from equatorial and polar great circles on a Bloch sphere with Pati's scheme, was achieved with one cbit communication. Such a RSP scheme can be generalized to prepare a large number of qubit states and may be used in other quantum information processing and quantum computing.

description: Deep Learning is a promising approach to either automate or simplify several tasks in the healthcare domain. In this work, we introduce SegAN-CAT, an approach to brain tumor segmentation in Magnetic Resonance Images (MRI), based on Adversarial Networks. In particular, we extend SegAN, successfully applied to the same task in a previous work, in two respects: (i) we used a different model input and (ii) we employed a modified loss function to train the model. We tested our approach on two large datasets, made available by the Brain Tumor Image Segmentation Benchmark (BraTS). First, we trained and tested some segmentation models assuming the availability of all the major MRI contrast modalities, i.e., T1-weighted, T1 weighted contrast-enhanced, T2-weighted, and T2-FLAIR. However, as these four modalities are not always all available for each patient, we also trained and tested four segmentation models that take as input MRIs acquired only with a single contrast modality. Finally, we proposed to apply transfer learning across different contrast modalities to improve the performance of these single-modality models. Our results are promising and show that not SegAN-CAT is able to outperform SegAN when all the four modalities are available, but also that transfer learning can actually lead to better performances when only a single modality is available.

description: We study the ground state properties and nonequilibrium dynamics of two spinor bosonic impurities immersed in a one-dimensional bosonic gas upon applying an interspecies interaction quench. For the ground state of two non-interacting impurities we reveal signatures of attractive induced interactions in both cases of attractive or repulsive interspecies interactions, while a weak impurity-impurity repulsion forces the impurities to stay apart. Turning to the quench dynamics we inspect the time-evolution of the contrast unveiling the existence, dynamical deformation and the orthogonality catastrophe of Bose polarons. We find that for an increasing postquench repulsion the impurities reside in a superposition of two distinct two-body configurations while at strong repulsions their corresponding two-body correlation patterns show a spatially delocalized behavior evincing the involvement of higher excited states. For attractive interspecies couplings, the impurities exhibit a tendency to localize at the origin and remarkably for strong attractions they experience a mutual attraction on the two-body level that is imprinted as a density hump on the bosonic bath.

description: Remarkable nonlinearities in the differential tunneling conductance between fractional quantum Hall edge states at a constriction are observed in the weak-backscattering regime. In the $ν$ = 1/3 state a peak develops as temperature is increased and its width is determined by the fractional charge. In the range $2/3 \le ν\le 1/3$ this width displays a symmetric behavior around $ν$ = 1/2. We discuss the consistency of these results with available theoretical predictions for inter-edge quasiparticle tunneling in the weak-backscattering regime.

description: Data-driven decision making related to individuals has become increasingly pervasive, but the issue concerning the potential discrimination has been raised by recent studies. In response, researchers have made efforts to propose and implement fairness measures and algorithms, but those efforts have not been translated to the real-world practice of data-driven decision making. As such, there is still an urgent need to create a viable tool to facilitate fair decision making. We propose FairSight, a visual analytic system to address this need; it is designed to achieve different notions of fairness in ranking decisions through identifying the required actions -- understanding, measuring, diagnosing and mitigating biases -- that together lead to fairer decision making. Through a case study and user study, we demonstrate that the proposed visual analytic and diagnostic modules in the system are effective in understanding the fairness-aware decision pipeline and obtaining more fair outcomes.

A Discontinuous Galerkin Finite Element Method with Turbulence Modelling for Incompressible Flows
Creators: name: Jolley, Luke
Publisher: name: University of Leicester
Year: 2019
Subjects: Uncategorized

description: This thesis explores the use of an innovative interior penalty Discontinuous Galerkin Finite Element Method (DGFEM) for the Reynolds averaged, incompressible Navier-Stokes equations, coupled with the k-w turbulence model. The simulation of incompressible flows is relatively inexpensive computationally, and, with appropriate assumptions, provides a good approximation to compressible flows. This makes them useful for large simulations, such as those required by the steam turbine industry. Current generation industrial CFD solvers require ad hoc user intervention with regards to solution refinement, in order to achieve numerical results with a sufficient degree of accuracy. Accurate simulations of curved blade geometries rely on a dense packing of straight edged elements in order to represent the geometry correctly. This results in extended simulation times and non-optimised numerical results.Curved boundary elements allow highly curved geometries to be represented by fewer mesh elements, enabling effective mesh refinement perpendicular to the boundary, without increasing mesh density parallel to the boundary. To achieve this, we propose a novel approach using inverse estimates to derive a new discontinuity-penalisation function which stabilises the DGFEM for computations in both two and three dimensions, on meshes consisting of standard shaped elements with general polynomial faces. Automated solution refinement is achieved by considering the dual-weighted-residual approach, defining a suitable numerical approximation for the dual solution, along with a target functional to drive the refinement. A novel continuation and refinement algorithm, along with a prototype DGFEM solver is developed, producing a number of interesting numerical results for high Reynolds number flows. These ideas are extended to incorporate the recent results in the literature for DGFEMs on general computational meshes consisting of polygonal elements. For high Reynolds number turbulent flows, we show that polygonal elements can be used to significantly reduce mesh density and the computational resources required for fluid simulations through several numerical experiments.
