description: Due to complex and volatile lighting environment, underwater imaging can be readily impaired by light scattering, warping, and noises. To improve the visual quality, Underwater Image Enhancement (UIE) techniques have been widely studied. Recent efforts have also been contributed to evaluate and compare the UIE performances with subjective and objective methods. However, the subjective evaluation is time-consuming and uneconomic for all images, while existing objective methods have limited capabilities for the newly-developed UIE approaches based on deep learning. To fill this gap, we propose an Underwater Image Fidelity (UIF) metric for objective evaluation of enhanced underwater images. By exploiting the statistical features of these images, we present to extract naturalness-related, sharpness-related, and structure-related features. Among them, the naturalness-related and sharpness-related features evaluate visual improvement of enhanced images; the structure-related feature indicates structural similarity between images before and after UIE. Then, we employ support vector regression to fuse the above three features into a final UIF metric. In addition, we have also established a large-scale UIE database with subjective scores, namely Underwater Image Enhancement Database (UIED), which is utilized as a benchmark to compare all objective metrics. Experimental results confirm that the proposed UIF outperforms a variety of underwater and general-purpose image quality metrics.

description: We introduce a new algorithm to construct travel time distances between a point in the interior of a Riemannian manifold and points on the boundary of the manifold, and describe a numerical implementation of the algorithm. It is known that the travel time distances for all interior points determine the Riemannian manifold in a stable manner. We do not assume that there are sources or receivers in the interior, and use the hyperbolic Neumann-to-Dirichlet map, or its restriction, as our data. Our algorithm is a variant of the Boundary Control method, and to our knowledge, this is the first numerical implementation of the method in a geometric setting.

description: Aim: Clarity on health expenditures is essential for the timely identification of risks that jeopardize the democratic provision of health services and the credibility of health insurance systems. Furthermore, observing health outcomes with geographical scope is essential for making multilateral associations. This study aimed at conveying information on the variability of important economic parameters of the health sector of Serbia and Greece from 2007 to 2012, when the most serious financial crisis in the post-war economic history hit the global economy. Methods: Exchange rates, purchase-power-parities (PPP) and price indices were used for the bilateral review of health and pharmaceutical expenditure dynamics during 2007-2012. Prescription and dispensing changes were also studied taking into account the anatomical therapeutic chemical (ATC) structure of drugs consumed. Results: Greece was forced to cut down its total health care and pharmaceutical expenditure and mainly its out-of-pocket payments were more seriously affected by the recession. Surprisingly, emerging market of Serbia, although severely damaged by global recession, succeeded to maintain 19% growth of its per capita health expenditure and even 25% increase of its per capita spending on pharmaceuticals. Innovative pharmaceuticals showed an upward trend in both countries. Conclusions: These two countries might serve as an example of two distinct pathways of mature and emerging health care markets during financial constraints caused by global recession. Our findings show that producing disease-based feedback, in the long run, may empower the assessment of the return on investment on medical technology and healthcare systems’ cost-effectiveness.

GEL estimation for heavy-tailed GARCH models with robust empirical likelihood inference
Creators: name: Prokhorov, Artem
name: Hill, Jonathan B.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: We construct a Generalized Empirical Likelihood estimator for a GARCH(1, 1) model with a possibly heavy tailed error. The estimator imbeds tail-trimmed estimating equations allowing for over-identifying conditions, asymptotic normality, efficiency and empirical likelihood based confidence regions for very heavy-tailed random volatility data. We show the implied probabilities from the tail-trimmed Continuously Updated Estimator elevate weight for usable large values, assign large but not maximum weight to extreme observations, and give the lowest weight to non-leverage points. We derive a higher order expansion for GEL with imbedded tail-trimming (GELITT), which reveals higher order bias and efficiency properties, available when the GARCH error has a finite second moment. Higher order asymptotics for GEL without tail-trimming requires the error to have moments of substantially higher order. We use first order asymptotics and higher order bias to justify the choice of the number of trimmed observations in any given sample. We also present robust versions of Generalized Empirical Likelihood Ratio, Wald, and Lagrange Multiplier tests, and an efficient and heavy tail robust moment estimator with an application to expected shortfall estimation. Finally, we present a broad simulation study for GEL and GELITT, and demonstrate profile weighted expected shortfall for the Russian Ruble–US Dollar exchange rate. We show that tail-trimmed CUE-GMM dominates other estimators in terms of bias, mse and approximate normality.
Macroeconomics and the reality of mixed frequency data
Creators: name: Ghysels, Eric
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Many time series are sampled at different frequencies. When we study co-movements between such series we usually analyze the joint process sampled at a common low frequency. This has consequences in terms of potentially mis-specifying the co-movements and hence the analysis of impulse response functions—a commonly used tool for economic policy analysis. We introduce a class of mixed frequency VAR models that allows us to measure the impact of high frequency data on low frequency and vice versa. Our approach does not rely on latent processes/shocks representations. As a consequence, the mixed frequency VAR is an alternative to commonly used state space models for mixed frequency data. State space models are parameter-driven whereas mixed frequency VAR models are observation-driven models as they are formulated exclusively in terms of observable data and do not involve latent processes as well as shocks and thus avoid the need to formulate measurement equations, filtering, etc. We also propose various parsimonious parameterizations, in part inspired by recent work on MIDAS regressions. We also explicitly characterize the mis-specification of a traditional common low frequency VAR and its implied mis-specified impulse response functions. The class of mixed frequency VAR models can also characterize the timing of information releases for a mixture of sampling frequencies and the real-time updating of predictions caused by the flow of high frequency information. Various estimation procedures for mixed frequency VAR models are also proposed, both classical and Bayesian. Numerical and empirical examples quantify the consequences of ignoring mixed frequency data.
Powering luminous core collapse supernovae with jets

Year: 2022
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: I examine recent fittings of luminous supernovae (LSNe) with extra energy sources of magnetar and helium burning and find that in about half of these LSNe the fitting parameters have some problems. In some LSNe the total energy of these two energy sources is larger than the kinetic energy of the ejecta that the fitting yields. In some others LSNe the total energy of the delayed neutrino explosion mechanism and these two extra sources combined is smaller than the kinetic energy that the fitting yields. These difficulties suggest that, like earlier claims that jets power superluminous supernovae (SLSNe), jets also power the less luminous LSNe. A magnetar might also supply energy. However, in most cases jets supply more energy than the magnetar, during the explosion and possibly at late times. I strengthen an earlier claim that jets launched at magnetar birth cannot be ignored. I explain the trend of maximum rise time for a given luminosity of hydrogen deficient core collapse supernovae (CCSNe), in particular LSNe and SLSNe, with a toy model of jets that are active for a long time after explosion.

description: This study experimentally investigates the temperature distribution and behavior of a 48V Lithium-Ion (Li-ion) battery pack during two charge-discharge cycles using 25 thermocouples. Results indicate that better convective heat transfer occurs at the external surfaces of the pack, while middle cells reach maximum temperatures. Differences are also observed in the behavior of the three modules. The discharge cycle shows a temperature rise of 5.8°C with a pack temperature gradient increasing from 1.3°C to 2.7°C. The study highlights the importance of assessing the thermal behavior of each module and the complexity of the Li-ion battery pack system. Findings on the battery cells, modules, and pack in the same study can provide valuable insights for designing efficient cooling systems for Li-ion battery packs.

description: When Morris and Thorne first proposed the possible existence of traversable wormholes, they adopted the following strategy: maintain complete control over the geometry, thereby leaving open the determination of the stress-energy tensor. In this paper we determine this tensor by starting with a noncommutative-geometry background and assuming that the static and spherically symmetric spacetime admits conformal motions. This had been established in a previous collaboration with Rahaman et al. using a slightly different approach. Accordingly, the main purpose of this paper is to show that the wormhole obtained can be made stable to linearized radial perturbations.

High-energy Gamma-rays from Magnetically Arrested Disks in Nearby Radio Galaxies

description: The origins of the GeV gamma-rays from nearby radio galaxies are unknown. Hadronic emission from magnetically arrested disks (MADs) around central black holes (BHs) is proposed as a possible scenario. Particles are accelerated in the MAD by magnetic reconnection and stochastic turbulence acceleration. We pick out the fifteen brightest radio galaxies in the GeV band from the Fermi 4LAC-DR2 catalog and apply the MAD model. We find that we can explain the data in the GeV bands by the MAD model if the accretion rate is lower than 0.1% of the Eddington rate. For a higher accretion rate, GeV gamma-rays are absorbed by two-photon interaction due to copious low-energy photons. If we assume another proposed prescription of the electron heating rate by magnetic reconnection, the MAD model fails to reproduce the GeV data for the majority of our sample. This indicates that the electron heating rate is crucial. We also apply the MAD model to Sgr A* and find that GeV gamma-rays observed at the Galactic center do not come from the MAD of Sgr A*. We estimate the cosmic ray intensity from Sgr A*, but it is too low to explain the high-energy cosmic ray intensity on Earth.

description: Professionalization of public health is important to advance public health education, training, and practice. In our opinion, there is no contradiction that the profession of public health consists of members of different other professions – which also have their own values and conducts. Yet, if professions work under the roof of public health, the pillars – the core values – of the house that is built are the common denominators. Making the guiding norms and values explicit is important for the self-definition of the professional field/profession and giving guidance in pursuing a fair and respectful improvement of population health.

description: Aim: Regional collaboration has continuously contributed to the development of public health in the South Eastern Europe (SEE) region since 2000 when the Public Health Collaboration in SEE (PH-SEE) was initiated. This article looks into two frameworks for regional collaboration in the area of public health: a framework developed in 2004 by a network of public health professionals and academics, and another one developed by the SEE Health Network as integral part of the SEE 2020 strategy on Jobs and Prosperity in a European Perspective, adopted in 2013. It compares the commonalities and differences of the two frameworks; considers what is still valid and relevant after ten years and which new features have emerged in the new strategy. Methods: A literature review was carried out and a qualitative analysis was applied for the comparison of the two frameworks. Results: Notwithstanding the time gap of nearly ten years, the commonalities between the two regional health strategies are significant. Major consistent goals include: improving equity in health; strengthening human resources for health; improving intersectoral cooperation and governance. The differences between the two regional strategies, including issues around social participation and regional health information systems, are partially due to their different development context. Cross-border policies and quality management have emerged as new or more pronounced topics in the SEE 2020 strategy’s health dimension. Conclusions: Many aspects addressed in the 2004 framework are pertinent with regard to the SEE 2020 health dimension and remain relevant in the current context. The integration of health as part of the economic SEE 2020 strategy reflects a significant paradigm shift and important step forward for public health.

description: High energy X-ray and ultraviolet (UV) radiation from young stars impacts planetary atmospheric chemistry and mass loss. The active $\sim 22$ Myr M dwarf AU Mic hosts two exoplanets orbiting interior to its debris disk. Therefore, this system provides a unique opportunity to quantify the effects of stellar XUV irradiation on planetary atmospheres as a function of both age and orbital separation. In this paper we present over 5 hours of Far-UV (FUV) observations of AU Mic taken with the Cosmic Origins Spectrograph (COS; 1070-1360 Angstrom) on the Hubble Space Telescope (HST). We provide an itemization of $120$ emission features in the HST/COS FUV spectrum and quantify the flux contributions from formation temperatures ranging from $10^4-10^7$ K. We detect 13flares in the FUV white-light curve with energies ranging from $10^{29} - 10^{31}$ ergs. The majority of the energy in each of these flares is released from the transition region between the chromosphere and the corona. There is a 100$\times$ increase in flux at continuum wavelengths $λ< 1100$ Angstrom in each flare which may be caused by thermal Bremsstrahlung emission. We calculate that the baseline atmospheric mass-loss rate for AU Mic b is $\sim 10^8$ g s$^{-1}$, although this rate can be as high as $\sim 10^{14}$ g s$^{-1}$ during flares with $L_\textrm{flare} \simeq 10^{33}$ erg s$^{-1}$. Finally, we model the transmission spectra for AU Mic b and c with a new panchromatic spectrum of AU Mic c and motivate future JWST observations of these planets.

An efficient semiparametric maxima estimator of the extremal index

description: The extremal index $θ$, a measure of the degree of local dependence in the extremes of a stationary process, plays an important role in extreme value analyses. We estimate $θ$ semiparametrically, using the relationship between the distribution of block maxima and the marginal distribution of a process to define a semiparametric model. We show that these semiparametric estimators are simpler and substantially more efficient than their parametric counterparts. We seek to improve efficiency further using maxima over sliding blocks. A simulation study shows that the semiparametric estimators are competitive with the leading estimators. An application to sea-surge heights combines inferences about $θ$ with a standard extreme value analysis of block maxima to estimate marginal quantiles.

description: In order to promote awareness of factors that affect social services, their quality, effectiveness and coverage, the term “governance” is frequently used. However, there is no agreement on definitions, frameworks and how it relates to the health sector. In this overview, two interrelated processes in Serbia will be analyzed: governance and management at the macro-, meso-, and micro level. Key messages are as follows: i) Continue decentralization and support to an effective national decision-making body (Health Council of Serbia) with all relevant stakeholders; ii) Reduce the well-known implementation gap and agree on a binding time frame for reforms, and; iii) Establish obligatory schemes for education and training of managers and support sustainability of state institutional capacity to teach, train and advise on a scientific basis.

description: MicroRNAs (miRs) are a family of non-coding RNAs that regulate gene expression. They are ubiquitous among multicellular eukaryotes and are also encoded by some viruses. Upon infection, viral miRs (vmiRs) can potentially target gene expression in the host and alter the immune response. While prior studies have reported viral infections in human pulps, the role of vmiRs in pulpal disease is yet to be explored. The purpose of this study was to examine the expression of vmiRs in normal and diseased pulps and to identify potential target genes.

description: Arsenic methyltransferase (As3mt) catalyzes the conversion of inorganic arsenic (iAs) to its methylated metabolites, including toxic methylarsonite (MAsIII) and dimethylarsinite (DMAsIII). Knockout (KO) of As3mt was shown to reduce the capacity to methylate iAs in mice. However, no data are available on the oxidation states of As species in tissues of these mice. Here, we compare the oxidation states of As species in tissues of male C57BL/6 As3mt-KO and wild-type (WT) mice exposed to arsenite (iAsIII) in drinking water. WT mice were exposed to 50 mg/L As and As3mt-KO mice that cannot tolerate 50 mg/L As were exposed to 0, 15, 20, 25 or 30 mg/L As. iAsIII accounted for 53% to 74% of total As in liver, pancreas, adipose, lung, heart, and kidney of As3mt-KO mice; tri- and pentavalent methylated arsenicals did not exceed 10% of total As. Tissues of WT mice retained iAs and methylated arsenicals: iAsIII, MAsIII and DMAsIII represented 55%–68% of the total As in the liver, pancreas, and brain. High levels of methylated species, particularly MAsIII, were found in the intestine of WT, but not As3mt-KO mice, suggesting that intestinal bacteria are not a major source of methylated As. Blood of WT mice contained significantly higher levels of As than blood of As3mt-KO mice. This study is the first to determine oxidation states of As species in tissues of As3mt-KO mice. Results will help to design studies using WT and As3mt-KO mice to examine the role of iAs methylation in adverse effects of iAs exposure.
Is Thermohaline Mixing the Full Story? Evidence for Separate Mixing Events near the Red Giant Branch Bump

description: The abundances of mixing--sensitive elements including lithium, [C/N], and 12C/13C are known to change near the red giant branch bump. The explanation most often offered for these alterations is double diffusive thermohaline mixing in the stellar interior. In this analysis, we investigate the ability of thermohaline mixing to explain the observed timing of these chemical depletion events. Recent observational measurements of lithium and [C/N] show that the abundance of lithium decreases before the abundance of [C/N], whereas numerical simulations of the propagation of the thermohaline mixing region computed with MESA show that the synthetic abundances drop simultaneously. We therefore conclude that thermohaline mixing alone cannot explain the distinct events of lithium depletion and [C/N] depletion, as the simultaneity predicted by simulations is not consistent with the observation of separate drops. We thus invite more sophisticated theoretical explanations for the observed temporal separation of these chemical depletion episodes as well as more extensive observational explorations across a range of masses and metallicities.

Methods: This study had a regional character. The national research team interviewed 175 randomly selected participants from Macedonia. The research was performed in the period March 2012 – March 2013. For the research purposes there were used especially designed questionnaires for cancer, stroke, myocardial infarction, diabetes mellitus and injuries. For assessment of the performances, the appropriate techniques were developed. Results: Macedonians consider public healthcare system as being medium-good in all aspects: accessibility, availability, quality of health care services and population’s confidence. The knowledgeable observers (N=125) believe that state-of-the-art treatment exist all over the country (“yes”: 33.6% and “rather yes”: 44.8%). They believe that the services are accessible to everybody, free of major charges (“yes”: 31.2% and “rather yes”: 45.6%). The individual witnesses (N=50) argued toward lack of pharmacies and proper medicines in rural areas, with a gap between the availability and quality of services in rural vs. urban areas. Conclusion: The future goals for Macedonia include better public healthcare financing, cost definition of health packages, improved disease prevention and effective human resources.

description: Aim: Our aim was to describe the trend over time and the demographic distribution of hemorrhagic stroke in Albania in the past decade. Methods: This study included all patients diagnosed with hemorrhagic stroke and admitted during the period 2004-2015 at the University Hospital Center “Mother Teresa” in Tirana (988 cases overall; 34% women; overall mean age: 57.8±19.3 years). Information about selected demographic characteristics was also collected for all study participants. Results: The proportion of older patients (≥70 years) was slightly, but not significantly, higher in women than in men (32% vs. 27%, respectively; P=0.163). Furthermore, the proportion of Tirana residents was similar in both sexes (47% in men vs. 45% in women). Overall, there was evidence of a significant linear trend over time (Mann-Kendall test: P<0.01), indicating a gradual increase in the number of hemorrhagic stroke cases in Albania for the period 2004-2015. Conclusion: This study provides useful information about the increasing trend of hemorrhagic stroke in Albania, a transitional country in Southeastern Europe which is characterized by rapid changes including unhealthy dietary habits.

description: Aim: This study aimed to explore and describe the barriers that elderly Lithuanians experience with respect to going to court or other institutions to defend their right not to be discriminated regarding medical care. Methods: We used a mixed methods approach due to the scarcity of information in Lithuania. First, the review of laws was done using the e-tar database and court cases were searched using the e-teismai database followed by policy analysis. Additional sources of information were identified searching Google Scholar and PubMed, as well as Google for grey literature. The keywords used were: ageism in patient care, discrimination against elderly, elderly and health (English and Lithuanian: 2000-2015). Secondly, we conducted in-depth individual interviews with 27 clients of newly-established integrated home care services: 13 elderly patients, and 14 informal caregivers. Results: This study identified five groups of barriers explaining why Lithuanian elderly are hesitant to fight discrimination in the health system. The results of the study disclose the following barriers that the elderly in Lithuania face: i) the lack of recognition of the phenomenon of discrimination against the elderly in patient care; ii) the lack of information for complaining and the fear of consequences of complaining; iii) the deficiencies and uncertainties of laws and regulations devoted to discrimination; iv) the high level of burden of proof in court cases and lack of good practices; v) the lack of a patient (human) rights-based approach in all policies and in education as well as the lack of intersectoral work. Conclusions: This study disclosed the need to: encourage training of legists and lawyers in expanding knowledge and skills in human rights in patient care; encourage training of health care professionals – the burden of leadership for this has to be assumed by universities and public health professionals; incorporate a new article in the ‘Law on the rights of patients and compensation for the damage to their health’, clearly stating where to complain in case of discrimination; create a webpage and brochures with readable and understandable information for elderly persons and their families and caregivers; establish legal consultation and mediation cabinets in health care facilities; establish an older persons’ rights protection service under the Ministry of Social Security and Labour in close cooperation with the Ministry of Health; promote sustainable results by incorporating a human rights-based approach regarding elderly persons in all policies.

description: An investigation of the isospin equilibration process in the reactions $^{58,64}$Ni+$^{58,64}$Ni at two bombarding energies in the Fermi regime ($32\,$MeV/nucleon and $52\,$MeV/nucleon) is presented. Data have been acquired during the first experimental campaign of the coupled INDRA-FAZIA apparatus in GANIL. Selecting from peripheral to semi-central collisions, both the neutron content of the quasiprojectile residue and that of the light ejectiles coming from the quasiprojectile evaporation have been used as probes of the dynamical process of isospin diffusion between projectile and target for the asymmetric systems. The isospin transport ratio technique has been employed. The relaxation of the initial isospin imbalance with increasing centrality has been clearly evidenced. The isospin equilibration appears stronger for the reactions at $32\,$MeV/nucleon, as expected due to the longer projectile-target interaction time than at $52\,$MeV/nucleon. Coherent indications of isospin equilibration come from the quasiprojectile residue characteristics and from particles ascribed to the quasiprojectile decay.

description: We show the existence of massive Dirac fermions in electronic band structures of a few Fe atomic layers with perpendicular magnetization. Based on a tight binding model fitted to ab-initio band structure, we observe four distinct massive Dirac fermions near the Fermi level, which result from atomic spin-orbit coupling of Fe and a band inversion between Fe $4s$-$3d_{x^2-y^2}$ hybrid orbital band and $3d_{xy}$ orbital band. These lead to a valence band with finite Chern integer (+2) and chiral edge modes near the Fermi level. When the chemical potential is set inside the Dirac gap by carrier doping, the Hall conductivity exhibits a plateau-like structure with quantized value $2\frac{e^2}{h}$, and orbital magnetization shows a prominent increase, latter of which is mostly due to chiral orbital motion of electrons along the edge modes. We discuss the stability of the Dirac fermions in Fe(001) monolayer on MgO(001) substrate and Fe(001) bilayer case.

description: Aim: Our aim was to assess the association of rheumatoid arthritis with socio-demographic characteristics and lifestyle factors among women in transitional Albania. Methods: A cross-sectional study was carried out in 2012-2013 including a sample of 2198 women aged 30 years and above who attended the Rheumatology services at primary health care clinics in Tirana municipality (mean age: 60.2±9.7 years; overall response rate: 95%). The diagnosis of rheumatoid arthritis was based on the American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) 2010 criteria. In addition, a structured questionnaire was administered to all study participants including information on demographic and socioeconomic characteristics and behavioral factors. Binary logistic regression was used to assess the association of rheumatoid arthritis with covariates. Results: Overall, 437 (19.9%) women were diagnosed with rheumatoid arthritis (both incident and prevalent cases). In multivariable-adjusted models, rheumatoid arthritis was positively and significantly related to older age (OR=1.8, 95%CI=1.3-2.6), a lower educational attainment (OR=1.4, 95%CI=1.1-1.9), smoking (OR=1.5, 95%CI=1.1-2.0), alcohol intake (OR=1.9, 95%CI=1.2-3.1) and overweight and obesity (OR=1.5, 95%CI=1.2-2.0 and OR=1.6, 95%CI=1.2-2.0, respectively). Conclusion: This study provides useful evidence about selected correlates of rheumatoid arthritis among women attending specialized primary health care services in Albania. Health professionals and policymakers in Albania should be aware of the magnitude and consequences of this chronic condition in the adult population.
