description: 3D surface reconstruction from point clouds is a key step in areas such as content creation, archaeology, digital cultural heritage, and engineering. Current approaches either try to optimize a non-data-driven surface representation to fit the points, or learn a data-driven prior over the distribution of commonly occurring surfaces and how they correlate with potentially noisy point clouds. Data-driven methods enable robust handling of noise and typically either focus on a global or a local prior, which trade-off between robustness to noise on the global end and surface detail preservation on the local end. We propose PPSurf as a method that combines a global prior based on point convolutions and a local prior based on processing local point cloud patches. We show that this approach is robust to noise while recovering surface details more accurately than the current state-of-the-art.

description: Analysis preceding and developed for Aotearoa New Zealand’s Te Ara Paerangi Future Pathways Green Paper Consultation can be combined with a systems perspective to suggest Aotearoa’s Research, Science and Innovation (RSI) system does not prioritise or respond as well as it should, and lacks coordinated strategies to address major issues. How can we assess concerns that potentially successful ideas and innovation are being stopped unnecessarily at systemic barriers, which could be removed in the current push for systemic reform?

 Ostrom’s eight principles for managing common pool resources provide a well-designed framework that can overcome the high level barriers, which may arise from hypercompetition and other dilemmas born out of the institutional structures and funding systems. There are at least three good options for implementing Ostrom’s principles in high level institutional and funding structures. These provide enabling conditions for ensuring that efforts to address workforce career issues, funding stability, and improved funding mechanisms lead to a more effective and responsive RSI system. A more compelling basis for enhanced funding levels, trust and self-organising prioritisation can come from: 1) a well-implemented base funding system, 2) implementation of Ostrom’s principles and values-driven approaches to rebuild trust, and 3) fellowships support that addresses the stress, connectivity and responsiveness issues currently observed.
Navigating Transition in the Health Sector: An issues paper of priority areas and practical recommendations for donors, countries and technical assistance

description: This issues paper provides a framework for discussions on transition of donors to lower levels of financial support in low and middle-income countries. Literature on transition, and its consequences for donors and countries remains limited, with no universal agenda or agreed best practices identified that result in a smooth transition for the cohort of countries approaching it right now. Our work focuses on the health sector, building on and complementing that of others, in particular the UHC2030 Technical Working Group on Transition and Sustainability, analyses of the projected impact of transition, and evaluations of previous transition processes, such as USAID family planning (FP) programme graduation. This analysis contributes to the debate on transition by highlighting priority areas and practical recommendations on how countries, donors and technical advisors can address transition for the health sector, both programmatically and financially in a sustainable way.
The redshift distribution of the X-ray background
Creators: name: Soltan, Andrzej M.

Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The X-ray background (XRB) is produced by a large number of faint sources distributed over a wide range of redshifts. The XRB carries information on the spatial distribution and evolution of these sources. The goals of the paper are: 1. to determine the redshift distribution of the soft X-ray background photons produced by all types of extragalactic sources, in order to relate fluctuations of the background to the large scale structures, 2. to determine the redshift distribution of the soft XRB produced by AGN in order to calculate the evolution of the AGN X-ray luminosity density. A set of major X-ray surveys is used to determine the redshift distributions of the X-ray sources selected at various flux levels. Simple analytic fits to the data allow us to determine the smooth relationship between the redshift distribution and the source flux. The redshift distribution of the integral XRB flux is obtained by averaging the fits over the source counts. It is shown that the distribution of extragalactic XRB photons in the 0.5-2 keV band is adequately represented by the function: dn/dlog z = 5.24 z^1.52 exp(-z/0.63). The huge voids postulated to explain the cold spots in the CMB maps create dips in the total XRB flux. However, the expected magnitude of the effect is comparable to the fluctuation amplitude of the XRB generated by the individual sources contributing to the background. The cosmic evolution of the AGN X-ray luminosity density up to redshift of ~5 is calculated in an elegant and straightforward way. Systematic uncertainties of the present method are assessed and shown to be small. At redshift greater than one the present results could be compared directly with some recent estimates obtained in a standard way and the agreement between both methods is very good.

description: The stellar mass-stellar metallicity relation (MZR) is an essential approach to probe the chemical evolution of galaxies. It reflects the balance between galactic feedback and gravitational potential as a function of stellar mass. However, the current MZR of local dwarf satellite galaxies (M* ~ 10^9.5 Msun, measured from integrated-light spectroscopy). Such a discrepancy may result from a systematic difference between the two methods, or it may indicate a break in the MZR around 10^9 Msun. To address this question, we measured the stellar metallicity of NGC 147 from integrated light using the Palomar Cosmic Web Imager (PCWI). We compared the stellar metallicity estimates from integrated light with the measurements from resolved stellar spectroscopy and found them to be consistent within 0.1 dex. On the other hand, the high-mass MZR overpredicts the metallicity by 0.6 dex at the mass of NGC 147. Therefore, our results tentatively suggest that the discrepancy between the low-mass MZR and high-mass MZR should not be attributed to a systematic difference in techniques. Instead, real physical processes cause the transition in the MZR. In addition, we discovered a positive age gradient in the innermost region and a negative metallicity gradient from the resolved stars at larger radii, suggesting a possible outside-in formation of NGC 147.

description: In South Africa public participation in decision making processes is entrenched in policy documents and formalised in the national Health Act, yet public participation rarely happens in practice. As the country aims to delivery Universal Health Coverage through a National Health Insurance (NHI) over the next few years policymakers will face challenges in terms of who and what to cover with their limited budget.  Priorities must be set that reflect health needs, economic resources and societal values.
While cost effective analyses (CEA) will address some components, they do not fully take into account social values, and there is need to build capacity among citizens, enhancing their understanding of resource allocation.
Alongside CEA, public engagement could ensure better priority setting approaches that are evidence based, ethical, legitimate, sustainable and inclusive which will be critical to the success of NHI. Public engagement could assist in developing the capacity of the public to understand the need for trade-offs where demands outweigh the available resources. In order to engage the public meaningfully these methods would need to be modified for the South African context.

description: The most widely used means of measuring the mass of black holes in Galactic binaries - specifically the X-ray novae - involves both radial velocity measurements of the secondary star, and photometric measurements of its ellipsoidal variability. The latter is important in constraining the inclination and mass ratio, and requires as direct a measure of the flux of the secondary as possible. Up to now, such measurements have been preferentially carried out in the NIR (1 -- 2.5$μm$), where the flux from the cooler secondary is expected to dominate over that from the accretion disc. However, here we present evidence of a significant non-stellar contribution to the NIR flux in many of those quiescent X-ray novae that are thought to contain a black hole primary. We discuss origins of this excess and the effect of such contamination on Galactic black hole mass measurements.

description: There is increasing need for useful tools to support healthcare decision-makers when allocating and consuming finite resources. This need may be even more significant in South Africa which has a complex health sector (made up of public and private healthcare practices with different patient populations and needs) that currently face considerable resource constraints and is in the process of major policy changes through the implementation of National Health Insurance (NHI).
Cochrane South Africa, the Centre for Evidence Based Health Care (CEBHC, University of Stellenbosch), and PRICELESS SA (University of Witwatersrand) collaborated on this survey of the South African clinical practice guideline (CPG) community to explore if and how cost-effectiveness, resource use and affordability evidence could be used practically to inform CPG development in South Africa.
The survey is a component of a larger project which aims to enhance the skills of CPG developers and users to make better use of health economic evidence (HEE) in CPG development, thereby enabling more informed decisions about the distribution of scarce health resources.
The cross-sectional online survey was distributed in October 2018 to 245 stakeholders selected with a purposive, snowball sampling method. The survey sample consisted of national CPG developers in South Africa. 60 responses were received (24.5% response rate) and the majority of the respondents were from a research or academic background.
Most respondents reacted positively to the use of HEE in CPGs. Limited technical capacity in South Africa was selected as the most important barrier to the use of HEE in CPGs, followed by the wide uncertainty in the results of economic evaluations due to analysis methods and/or lack of reliable data. Affordability (budget impact) was considered the most important HEE topic selection criterion, followed by high-level uncertainty about an intervention’s cost-effectiveness and the availability of robust data.

description: We study the Lorentz invariance of D=4 and 6 superstrings in the double-spinor formalism, which are equivalent to the D=4 and 6 superstrings in the pure-spinor formalism in the sense of the BRST cohomology. We first re-examine how the conformal and Lorentz anomalies appear in the D=4 and 6 Green-Schwarz superstrings in the semi-light-cone gauge in the framework of BRST quantization. We construct a set of BRST invariant Lorentz generators and show that they do not form a closed algebra, even cohomologically. We then turn to the construction of Lorentz generators in the D=4 and 6 double-spinor superstrings, and show that the Lorentz invariance is again anomalous. We also discuss the relation between the anomaly-free Lorentz generators in the lower-dimensional pure-spinor formalisms and that obtained in this paper.

description: The characters of simple Lie algebras are naturally decomposed into lattice polytope sums. The Brion formula for those polytope sums is remarkably similar to the Weyl character formula. Here we start to investigate if other character formulas have analogs for lattice polytope sums, by focusing on the Demazure character formulas. Using Demazure operators, we write expressions for the lattice sums of the weight polytopes of rank-2 simple Lie algebras, and the rank-3 algebra $A_3$.

description: This paper introduces the concept of fitness cloud as an alternative way to visualize and analyze search spaces than given by the geographic notion of fitness landscape. It is argued that the fitness cloud concept overcomes several deficiencies of the landscape representation. Our analysis is based on the correlation between fitness of solutions and fitnesses of nearest solutions according to some neighboring. We focus on the behavior of local search heuristics, such as hill climber, on the well-known NK fitness landscape. In both cases the fitness vs. fitness correlation is shown to be related to the epistatic parameter K.

description: Carbon is an essential element for life but its behavior during Earth's accretion is not well understood. Carbonaceous grains in meteoritic and cometary materials suggest that irreversible sublimation, and not condensation, governs carbon acquisition by terrestrial worlds. Through astronomical observations and modeling we show that the sublimation front of carbon carriers in the solar nebula, or the soot line, moved inward quickly so that carbon-rich ingredients would be available for accretion at 1 au after the first million years. On the other hand, geological constraints firmly establish a severe carbon deficit in Earth, requiring the destruction of inherited carbonaceous organics in the majority of its building blocks. The carbon-poor nature of the Earth thus implies carbon loss in its precursor material through sublimation within the first million years.

description: Air pollution is one of the major risk factors contributing to adverse public health outcomes worldwide. Fine particulate matter (PM2.5) has been repeatedly associated with increased risk of cardiovascular events, including heart attacks. Because PM2.5 is unequally distributed with elevated concentrations near high-traffic and industrial zones, PM2.5 is an environmental justice issue of major public health concern. In this study, we reviewed the relationship between PM2.5, emergency visits due to heart attacks, and environmental justice in San Diego County using data from CalEnviroScreen 3.0. Our results indicate that PM2.5, diesel PM emissions, and emergency visits due to heart attacks are weakly, but positively correlated (r = 0.3, R2 Implications: Particulate matter is an adverse contributor to overall health throughout the lifespan, contributing to diseases such as asthma, hypertension, stroke, and increased risk of cardiovascular events. Here, we assess the relationship between particulate matter and heart attacks in San Diego County using CalEnviroScreen3.0. Using these tools, we also examine correlations between this relationship and different sociodemographic indicators such as age, race, income, and proximity to the high-traffic U.S.–Mexico border. Overall, we show that specific communities around San Diego are more highly exposed to particulate matter, and that these relationships may be disproportionately contributing to heart attacks in disadvantaged communities.

description: During the formation of terrestrial planets, volatile loss may occur through nebular processing, planetesimal differentiation, and planetary accretion. We investigate iron meteorites as an archive of volatile loss during planetesimal processing. The carbon contents of the parent bodies of magmatic iron meteorites are reconstructed by thermodynamic modelling. Calculated solid/molten alloy partitioning of C increases greatly with liquid S concentration and inferred parent body C concentrations range from 0.0004 to 0.11 wt.%. Parent bodies fall into 2 compositional clusters characterized by cores with medium, and low C/S. Both of these require significant planetesimal degassing, as metamorphic devolatilization on chondrite-like precursors is insufficient to account for their C depletions. Planetesimal core formation models, ranging from closed system extraction to degassing of a wholly molten body, show that significant open system silicate melting and volatile loss is required to match medium and low C/S parent body core compositions. Greater depletion in C relative to S is the hallmark of silicate degassing, indicating that parent body core compositions record processes that affect composite silicate/iron planetesimals. Degassing of bare cores stripped of their silicate mantles would deplete S with negligible C loss, and could not account for inferred parent body core compositions. Devolatilization during small-body differentiation is thus a key process in shaping the volatile inventory of terrestrial planets derived from planetesimals and planetary embryos.

description: Non-reciprocal plasmons in current-driven, isotropic, and homogenous graphene with proximal metallic gates is theoretically explored. Nearby metallic gates screen the Coulomb interactions, leading to linearly dispersive acoustic plasmons residing close to its particle-hole continuum counterpart. We show that the applied bias leads to spectral broadband focused plasmons whose resonance linewidth is dependent on the angular direction relative to the current flow due to Landau damping. We predict that forward focused non-reciprocal plasmons are possible with accessible experimental parameters and setup.

description: Antihydrogen production by charge exchange reaction between Positronium (Ps) atoms and antiprotons requires an efficient excitation of Ps atoms up to high-n levels (Rydberg levels). In this study it is assumed that a Ps cloud is produced within a relatively strong uniform magnetic field (1 Tesla) and with a relatively high temperature (100 K). Consequently, the structure of energy levels are deeply modified by Zeeman and motional Stark effects. A two-step laser light excitation, the first one from ground to n=3 and the second from this level to a Rydberg level, is proposed and the physics of the problem is discussed. We derive a simple formula giving the absorption probability with substantially incoherent laser pulses. A 30% population deposition in high-$n$ states can be reached with feasible lasers suitably tailored in power and spectral bandwidth.

description: Using total petroleum hydrocarbon (TPH) measurements as a tool for assessing potential human health risks associated with exposures to petroleum products in the environment poses unique challenges, as TPH represents highly variable and complex mixtures containing hundreds of individual chemicals with wide-ranging chemical and physical properties. Current risk assessment practice generally involves analysis of environmental samples for various TPH fractions and summation of risk across those fractions. The United States Environmental Protection Agency (USEPA) derived provisional toxicity criteria for low, medium, and high carbon range aromatic and aliphatic hydrocarbon fractions over a decade ago. These criteria have been used, in whole or in part, to derive risk-based cleanup levels for TPH contamination in soil and groundwater. Herein, we evaluate and update oral and inhalation toxicity criteria for two of these fractions—medium carbon range aromatics and aliphatics—using, where applicable, newer data, updated modeling techniques, and new/alternative analyses of certain endpoints, human relevance, and uncertainty. The results of the analyses support an ~10-fold increase in the USEPA provisional reference concentration (p-RfC) values from 0.1 mg/m3 to 1 mg/m3 for both medium carbon range aromatics (different uncertainty factor) and aliphatics (new study and different judgement of toxicity data from existing study). Compared to the USEPA provisional oral reference dose (p-RfD) values for the medium carbon range aromatics and aliphatics of 0.03 mg/kg-day and 0.01 mg/kg-day, respectively, the present analyses suggest the RfD for medium carbon range aromatics could be increased >6.6-fold to 0.2 mg/kg-day (updated modeling and different uncertainty factors), and the RfD for medium carbon range aliphatics could be increased ~20-fold to 0.2 mg/kg-day (new study). These updated toxicity criteria could be used by regulatory agencies to re-evaluate risk-based screening levels or by risk managers to support cleanup levels for medium carbon range aromatics and aliphatics, while still ensuring adequate health protection.

description: Robust design optimization (RDO) of large-scale engineering systems is computationally intensive and requires significant CPU time. Considerable computational effort is still required within conventional meta-model assisted RDO frameworks. The primary objective of this article is to minimize further the computational requirements of meta-model assisted RDO by developing a global two-layered approximation based RDO technique. The meta-model in the inner layer approximates the response quantity and the meta-model in the outer layer approximates the response statistics computed from the response meta-model. This approach eliminates both model building and Monte Carlo simulation from the optimization cycle, and requires considerably fewer actual response evaluations than a single-layered approximation. To demonstrate the approach, two recently developed compressive sensing enabled globally refined Kriging models have been utilized. The proposed framework is applied to one test example and two real-life applications to illustrate clearly its potential to yield robust optimal solutions with minimal computational cost.

description: We study the membrane wrapping mode corrections to the Kaluza-Klein (KK) 6-brane in eleven dimensions. We examine the localized KK6-brane in the extended space in $E_{7(7)}$ exceptional field theory. In order to discuss the physical origin of the localization in the extended space, we consider a probe M2-brane in eleven dimensions. We show that a three-dimensional $\mathcal{N} = 4$ gauge theory is naturally interpreted as a membrane generalization of the two-dimensional $\mathcal{N} = (4,4)$ gauged linear sigma model for the fundamental string. We point out that the vector field in the $\mathcal{N}= 4$ model is identified as a dual coordinate of the KK6-brane geometry. We find that the BPS vortex in the gauge theory gives rise to the violation of the isometry along the dual direction. We then show that the vortex corrections are regarded as an instanton effect in M-theory induced by the probe M2-brane wrapping around the M-circle.

description: Universal health coverage (UHC) aims to  "ensure that all people can use the promotive, preventive, curative, rehabilitative and palliative health services they need, and that these are of sufficient quality to be effective, while also ensuring that the use of these services does not expose the user to financial hardship", according to the World Health Organization. There is an urgent need to place quality of care in the fabric of global, regional and country level action plans in order to make progress towards effective UHC. Hospital Accreditation (HA) is one of the mechanisms which encourages continuous quality improvement across levels of healthcare facilities and can address this need. This policy brief is a part of a series reflecting on Thailand’s experience of implementing universal health coverage.

description: Gravitational radiation-reaction phenomena occurring in the dynamics of inspiralling compact binary systems are investigated at the first post-Newtonian order beyond the quadrupole approximation in the context of Einstein-Cartan theory, where quantum spin effects are modeled via the Weyssenhoff fluid. We exploit balance equations for the energy and angular momentum to determine the binary orbital decay until the two bodies collide. Our framework deals with both quasi-elliptic and quasi-circular trajectories, which are then smoothly connected. Key observables like the laws of variation of the orbital phase and frequency characterizing the quasi-circular motion are derived analytically. We conclude our analysis with an estimation of the spin contributions at the merger, which are examined both in the time domain and the Fourier frequency space through the stationary wave approximation.

description: Recent trends in path planning have led to a proliferation of studies that find solutions to the path planning problems in an unknown cluster environment. This study aims to find an optimum impact-free path length for a mobile robot with a multi-objective optimization approach. The multi-objective optimization problem is formulated by using path length and a safety aspect as the two objectives. A hybrid population-based optimization algorithm, i.e. the hybrid particle swarm and chemical reaction optimization (HPCRO) algorithm, has been used to obtain a smooth path for the robot in an unknown environment with circular and/or polygonal obstacles. The results of the HPCRO algorithm are then compared with those of genetic algorithms, chemical reaction optimization and particle swarm optimization. Some statistical tests are performed to illustrate the superiority and potential applicability of the hybrid algorithm. The results of the hybrid algorithm are encouraging in terms of cost function value and computational cost.
