DIFFERENCES IN LIFE-SATISFACTION, OPTIMISM AND PESSIMISM BETWEEN HYPERTENSIVE AND NON-HYPERTENSIVE ADULTS
Creators: name: Szabo, Attila

Subjects: Blood pressure; Hypertension; Optimism; Pessimism; Satisfaction with life

description: Cross-national epidemiological research reveals that life satisfaction is related to blood pressure status.While no studies have yet distinguished hypertensive and normotensive individuals in terms of life satisfaction, limited evidence suggests that the former might differ in optimism and pessimism from the latter. The objective of this cross-sectional study was to test the hypothesis that hypertensive adults differ in life satisfaction, optimism and pessimism from the non-hypertensives. Individuals presenting themselves for a voluntary cardiovascular screening test (N = 128) were asked to complete three questionnaires assessing their satisfaction with life, optimism and pessimism. Based on their blood pressure readings, using the commonly accepted cut-off value of 140/90 mm Hg, participants were categorized as hypertensives and non-hypertensives and were compared on the dependent measures. A bootstrappedmultivariate analysis of covariance, using gender, bodymass index, smoking status and age as covariates, indicated that hypertensive participants reported lower life satisfaction and optimism than non-hypertensives. However, there was no difference in pessimism between the groups. These findings support the earlier epidemiological reports connecting life satisfaction and blood pressure status and expand those by showing that hypertensives differ from non-hypertensives in the subjective perception of their quality of life.

description: Mining graph data has become a popular research topic in computer science and has been widely studied in both academia and industry given the increasing amount of network data in the recent years. However, the huge amount of network data has posed great challenges for efficient analysis. This motivates the advent of graph representation which maps the graph into a low-dimension vector space, keeping original graph structure and supporting graph inference. The investigation on efficient representation of a graph has profound theoretical significance and important realistic meaning, we therefore introduce some basic ideas in graph representation/network embedding as well as some representative models in this chapter.

Neutrino properties and the decay of the lightest supersymmetric particle

description: Supersymmetry with broken R-parity can explain the neutrino mass squared differences and mixing angles observed in neutrino oscillation experiments. In the minimal model, where R-parity is broken only by bilinear terms, certain decay properties of the lightest supersymmetric particle (LSP) are correlated with neutrino mixing angles. Here we consider charginos, squarks, gluinos and sneutrinos being the LSP and calculate their decay properties in bilinear R-parity breaking supersymmetry. Together with the decays of charged scalars and neutralinos calculated previously this completes the proof that bilinear R-parity breaking as the source of neutrino masses will be testable at future colliders. Moreover, we argue that in case of GMSB, the decays of the NLSP can be used to test the model.

description: The Sersic law reproduces very well the surface brightness profile of early-type galaxies, and therefore is routinely used in observational and theoretical works. Unfortunately, its deprojection can not be expressed in terms of elementary functions for generic values of the shape parameter $n$. Over the years, different families of approximate deprojection formulae have been proposed, generally based on fits of the numerical deprojection over some radial range. We searched for a very simple, accurate, and theoretically motivated deprojection formula of the Sersic law, without free parameters, not based on fits of the numerical deprojection, and holding for generic $n > 1$. The formula has been found by requiring it to reproduce the analytical expressions for the inner and outer asymptotic expansions of the deprojected Sersic law of given $n$, and by matching the two expansions at intermediate radii with the request that the total luminosity coincides with that of the original Sersic profile of same $n$. The resulting formula is algebraically very simple, by construction its inner and outer parts are the exact (asymptotic) deprojection of the Sersic law, and it depends on two coefficients that are analytical functions of $n$ of immediate evaluation. The accuracy of the formula over the whole radial range is very good and increases for increasing $n$, with maximum relative deviations from the true numerical deprojection of $\simeq 8\,10^{-3}$ for the de Vaucouleurs profile. In the Appendix, the extension of the proposed formula to profiles with $n <1$ is also presented and discussed. The formula obtained is a useful tool of simple use in the modeling of early-type galaxies. Its ellipsoidal generalization is immediate.

description: Nigeria's structural adjustment program (SAP) appears, on balance, to have favorably affected Nigerian agricultural production, prices, employment, and agriculture's contributions to gross domestic product and foreign exchange earnings. However, the negative effects on food consumption, trade, and socioeconomic factors have tended to undermine gains from SAP. Some of these effects are partly attributable to the ban on certain food imports that, although not formally part of SAP, have continued in effect after SAP ended in 1988. Removal of such trade barriers would result in a rapid rise of U.S. exports to Nigeria.

We obtain a characterization of the hyperbolic geometry among all the Hilbert geometry in terms of area of ideals triangles. We also obtain a sharp lower bound on the hilbert area of ideal triangles, independant of the convex, which characterizes the triangle domains in the plane. Furthermore, under specific geometric assumptions, we obtain an upper bound, which depends on the convex domain.

description: We investigate the chemical evolution of the Milky Way disc exploring various schemes of recent (last several Gyr) star formation episodes, as reported in recent observational works. We use a semi-analytical model with parametrized radial migration and we introduce gaussian star formation episodes constrained by those recent observations. We find significant impact of the star formation episodes on several observables, like the local age-metallicity and [alpha/Fe] vs metallicity relations, as well as the local stellar metallicity distribution or the existence of young [alpha/Fe]-rich stars. Moreover, we show that the recently found "wiggly" behaviour of the disk abundance gradient with age can be interpreted in terms of either star formation or infall episodes.

INVESTIGATING THE LOCUS OF THE PHONOLOGICAL DEFICIT IN GREEK CHILDREN WITH DYSLEXIA AND DEVELOPMENTAL LANGUAGE DISORDER: DEGRADED PHONOLOGICAL REPRESENTATIONS OR DEFICIENT PHONOLOGICAL ACCESS?

description: The objective of the study was to investigate the locus of the phonological deficit in Greek children with dyslexia and Developmental Language Disorder (hereafter children with DDLD) by testing the Degraded Phonological Representations Hypothesis and the Deficient Phonological Access Hypothesis. Sixty-six children with DDLD aged 7-12 years and 63 typically developing (TD) children aged 7-12 years, all monolingual Greek speakers, were assessed with phoneme deletion, nonword repetition, rapid automatic naming, and spelling tasks, in addition to a range of language and reading tasks. The DDLD group performed significantly poorly on phoneme deletion tasks loading on phonological short-term memory capacity. Further, a qualitative analysis of spelling errors revealed that themajority of errors (96%)made by the DDLD group did not change the phonology of the spelled words, showing that mainly nonphonological difficulties account for poor spelling accuracy performance in Greek children with DDLD. The findings are consistent with the view that phonological representations of children with dyslexia and DLD are intact, but less accessible.

description: Two experiments were conducted in order to test whether suffering as a result of bullying affects the perceived humanness of the victims. We hypothesized that observers who are confronted with suffering and passive endurance of victimization will view victims as less than human. We propose a double dehumanization of victims, that is, denial of both their human uniqueness and human nature.We also hypothesized that victims’ defending themselves and deploying agency rather than passivity, has a humanizing effect on observers’ perceptions of the victims. Suffering wasmanipulated via vignettes describing bullying incidents experienced by both children and adult victims. Study 1 (N = 197) fully corroborated our first hypothesis. Study 2 (N = 164) replicated the findings of Study 1 and additionally showed that victims’ defense of themselves before harm-doers had a doubly humanizing effect on them (i.e., attribution of higher uniquely human but also human nature traits). These results provided support to our second hypothesis. Findings are discussed in terms of perceivers’ detachment from those who display passivity instead of agency in conditions that involve suffering.

description: Theoretical predictions of element yields from the rapid neutron capture (r-) process are subject to large uncertainties due to incomplete knowledge of nuclear properties and approximative hydrodynamical modeling of matter ejection. A major source of uncertainty in determining ejecta composition and radioactive decay heat is the lack of nuclear mass data for exotic neutron-rich nuclei produced during neutron irradiation.
 We examine both model (systematic) and parameter (statistical) uncertainties affecting nuclear mass predictions and their impact on r-process nucleosynthesis, and consequently, the composition of neutron star merger ejecta. To estimate the effect of model uncertainties, we consider five nuclear mass models that accurately describe known masses. We also use a backward-forward Monte Carlo method to estimate uncorrelated uncertainties from local variations in model parameters, constraining them to experimentally known masses before propagating them to unknown masses of neutron-rich nuclei.
 These mass uncertainties are then applied to a 1.38-1.38 M$_{\odot}$ neutron star merger model, considering a wide range of ejecta trajectories. We find that uncorrelated parameter uncertainties lead to ejected abundance uncertainties of 20% up to A $\simeq$ 130, 40% between A=150 and 200, with peaks around A $\simeq$ 140 and A $\simeq$ 203, leading to deviations of 100-300%. While correlated model uncertainties generally exceed parameter uncertainties for most nuclei, both have a significant impact on heavy element production.
 Overall, improvements in nuclear models are essential to reducing uncertainties in r-process predictions. Both correlated model uncertainties and coherent determination of parameter uncertainties are crucial for sensitivity analysis in r-process nucleosynthesis.

description: Differential cross-sections for quasi-free $π^0$ photoproduction from the proton and neutron bound in the deuteron have been measured for $E_γ= 200 - 400$ MeV at $θ^{\rm lab}_γ= 136.2^\circ$ usind the Glasgow photon tagger at MAMI, the Mainz 48 cm $\varnothing$ $\times$ 64 cm NaI(Tl) photon detector and the Göttingen SENECA recoil detector. For the proton measurements made with both liquid deuterium and liquid hydrogen targets allow direct comparison of "free" $π^0$ photoproduction cross-sections as extracted from the bound proton data with experimental free cross sections which are found to be in reasonable agreement below 320 MeV. At higher energies the "free" cross sections extracted from quasifree data are significantly smaller than the experimental free cross sections and theoretical predictions based on multipole analysis. For the first time, "free" neutron cross sections have been extracted in the $Δ$-region. They are also in agreement with the predictions from multipole analysis up to 320 MeV and significantly smaller at higher photon energies.

They essentially follow from the hierarchy of scales in these systems, which can be efficiently exploited using non-relativistic effective field theories. In particular, we discuss under which conditions non-relativistic potential models emerge as effective theories of QCD.

The electrons in this well occupy an out-of-plane conduction-band valley, rendering a system similar to two-dimensional electrons in Si-MOSFETs but with only one valley occupied. We observe an enhancement of the spin susceptibility over the band value that increases as the density is decreased, following closely the prediction of quantum Monte Carlo calculations and continuing at finite values through the metal-insulator transition.

Using this relationship, we argue that the more severe hierarchy of the charge-$\frac{2}{3}$ quark masses requires that the CKM matrix be close to a unit matrix whereas the milder hierarchy of the neutrino masses allows the PMNS matrix to depart markedly from the CKM matrix and contain large mixing angles of the type that are observed.

description: USDA's quarterly forecasts of fiscal year agricultural exports by commodity and region were examined for their reliability in predicting annual changes during 1977-89. Most of the forecasts were strongly correlated with actual exports. Most obvious exceptions probably stemmed from rounding errors. Bias was not a problem for the forecasts of total exports in any quarter, nor for most of the commodity forecasts. There was some upward bias in the forecasts for less developed countries, and downward bias for some developed countries. The USDA forecasts were conservative; they were more likely to underestimate the magnitude of change than to overestimate it.

description: Context. The Spectrometer/Telescope for Imaging X-Rays (STIX) onboard Solar Orbiter was designed to observe solar flares in the X-ray range of 4-150 keV, providing spectral, temporal and spatial information. Besides 30 imaging detectors, STIX has two additional detectors, the coarse flare locator (CFL) and the background (BKG) detector. Flares observed from Earth are classified using their peak X-ray flux observed by the GOES satellites. Roughly half of all flares observed by STIX are located on the backside of the Sun. These flares lack a GOES-class classification.
 Aims. In this paper, we describe the calibration of the BKG detector aperture sizes. Using the calibrated measurements of the BKG detector, we explore the relationship between the peak flux for flares jointly observed by STIX and GOES. This allows us to estimate the GOES flare classes of backside flares using STIX measurements.
 Methods. We looked at the 500 largest flares observed by both STIX and GOES in the time range Feb. 21 to Apr. 23. Aperture size calibration is done by comparing 4-10 keV counts of the BKG detector with the CFL measurements. In a second step, we correlate the calibrated STIX BKG peak flux with the GOES peak flux for individual flares.
 Results. We calibrated the BKG detector aperture sizes of STIX. Further, we showed that for the larger flares a close power law fit exists between the STIX BKG and GOES peak flux with a Pearson correlation coefficient of 0.97. This correlation provides a GOES proxy with a one sigma uncertainty of 11%. We were able to show that the BKG detector can reliably measure a broad range of GOES flare classes from roughly B5 up to at least X85 (assuming a radial distance of 1AU), making it an interesting detector-concept for future space weather missions. The largest flare observed by STIX to date is an estimated X16.5 $\pm$ 1.8 backside flare on the 20 Mai 2024.

description: Many regional scientists employ methods designed to "share down" to States or regions national input/output (I/O) data or coefficients. Much of the data supporting the agricultural sectors of the national I/O tables are compiled from State-level estimates. This report uses these actual State commodity output values, aggregated to the 17 agricultural I/O sectors, to "build up" to national I/O commodity output tables published by the U.S. Department of Commerce for 1982. These tables provide the basic foundation of a workable I/O model. The author explains the methodology used to determine State and sectoral distributions of nonmarketed outputs in areas where estimation was unavoidable. The author also highlights special problems and difficulties building these types of accounts.
Effects of Dust Scattering in Expanding Spherical Nebulae

Subjects: subject: Astrophysics (astro-ph)

description: The mean intensity of planetary nebulae with an expanding atmosphere is modeled by considering dusty and dust-free atmospheres. The bulk matter density is determined from the adopted velocity field through the equation of continuity. The gas is assumed to consist of hydrogen and helium and the gas-to-dust mass ratio is taken to be $3\times10^{-4}$. The Rayleigh phase function is employed for atomic scattering while the full Mie theory of scattering is incorporated for determining the dust scattering and absorption cross-section as well as the phase function for the angular distribution of photons after scattering. It is shown that in a dust free atmosphere, the mean intensity increases with the increase in the expansion velocity that makes the medium diluted. The mean intensity profile changes significantly when dust scattering is incorporated. The increase in forward scattering of photons by the dust particles yields into an increase in the mean intensity as compared to that without dust. The mean intensity increases as the particle size is increased. Thus it is shown that both the expansion of the medium and the presence of dust play important role in determining the mean intensity of a planetary nebulae.

description: Factors influencing the adoption of Integrated Pest Management (IPM) techniques are studied using survey data from individual vegetable producers from Florida, Michigan, and Texas. Farmers who adopt IPM tend to be less risk averse and use more managerial time on farm activities than nonadopters. Adopters are also more likely to operate large, irrigated farms and use more family labor. Locational factors and the type of crop grown are also influential in IPM adoption. The analysis is based on a logit framework and introduces adopter categories first conceptualized by rural sociologists.

description: We propose that semiflexible polymers in poor solvent collapse in two stages. The first stage is the well known formation of a dense toroidal aggregate. However, if the solvent is sufficiently poor, the condensate will undergo a second structural transition to a twisted entangled state, in which individual filaments lower their bending energy by additionally orbiting around the mean path along which they wind. This ``topological ripening'' is consistent with known simulations and experimental results. It connects and rationalizes various experimental observations ranging from strong DNA entanglement in viral capsids to the unusually short pitch of the cholesteric phase of DNA in sperm-heads. We propose that topological ripening of DNA toroids could improve the efficiency and stability of gene delivery.

description: The combination of strong disorder and interactions in closed quantum systems can lead to many-body localization (MBL). However this quantum phase is not stable when the system is coupled to a thermal environment. We investigate how MBL is destroyed in systems that are weakly coupled to a dephasive Markovian environment by focusing on their entanglement dynamics. We numerically study the third Rényi negativity $R_3$, a recently proposed entanglement proxy based on the negativity that captures the unbounded logarithmic growth in the closed case and that can be computed efficiently with tensor networks. We also show that the decay of $R_3$ follows a stretched exponential law, similarly to the imbalance, with however a smaller stretching exponent.

description: Chemical-disease relation (CDR) extraction is significantly important to various areas of biomedical research and health care. Nowadays, many large-scale biomedical knowledge bases (KBs) containing triples about entity pairs and their relations have been built. KBs are important resources for biomedical relation extraction. However, previous research pays little attention to prior knowledge. In addition, the dependency tree contains important syntactic and semantic information, which helps to improve relation extraction. So how to effectively use it is also worth studying. In this paper, we propose a novel convolutional attention network (CAN) for CDR extraction. Firstly, we extract the shortest dependency path (SDP) between chemical and disease pairs in a sentence, which includes a sequence of words, dependency directions, and dependency relation tags. Then the convolution operations are performed on the SDP to produce deep semantic dependency features. After that, an attention mechanism is employed to learn the importance/weight of each semantic dependency vector related to knowledge representations learned from KBs. Finally, in order to combine dependency information and prior knowledge, the concatenation of weighted semantic dependency representations and knowledge representations is fed to the softmax layer for classification. Experiments on the BioCreative V CDR dataset show that our method achieves comparable performance with the state-of-the-art systems, and both dependency information and prior knowledge play important roles in CDR extraction task.

description: Observations of companions of solar-type stars in nearby young moving groups (NYMGs) show that they split into two groups: stellar and brown dwarf companions (mass ratio $q>0.05$) and Jupiter-like (JL) planets ($q<0.02$). The frequency of JL planets in NYMGs appears to be higher than that obtained from radial velocity (RV) surveys. We extended the search for companions to three nearby clusters of intermediate age: Hyades, Coma Berenices, and Ursa Major. They are older and formed in more massive events than the NYMGs. The sample of host stars is complete for the core of the clusters, while we considered only a fraction of the tidal tails. We used the same methods considered for the members of NYMGs. We obtained a fairly complete sample of stellar companions and detected six massive JL planets. We found a lower frequency of equal-mass companions than in the NYMGs; this might be related to how binaries form in these environments. We also observed a concentration of stellar binaries in the cores of Ursa Major and Coma Berenices; we attribute this to the selective loss of low-mass systems. The observed scarcity of wide companions in Hyades can be due to the destruction of binaries in close encounters. The frequency of JL planets is lower than in the NYMGs but similar to that obtained from RV surveys. This extends the correlation with age and mass previously found for NYMGs. Results of this study alone do not indicate whether age or mass are the factors driving the observed correlation. A comparison of the frequencies of free-floating planets from microlenses and in young associations favours mass as the main driving parameter. Once the initial cluster mass function is considered, the frequency of JL planets in NYMGs is consistent with the results obtained using RVs.

description: “In recent years, multi-material designs of technical components have been gaining in importance. When combining different materials in a single component, it is possible to achieve high performance and extended functionality while simultaneously saving cost-intensive or rare materials. One promising approach to manufacture hybrid parts such as bi-metal gears is the utilization of the technology of tailored forming. This technology includes three main process steps: producing of bi-metal workpieces, forming and finishing. At the example of bevel gears, bi-metal preforms were produced by laser cladding of the martensitic steel X45CrSi9-3 on a cylindrical substrate made of the carbon steel C22.8 and formed to the final gear geometry by means of hot die forging. Subsequently, the hot bevel gears were directly quenched from hot-forming temperature by an air-water spray and self-tempered using the residual heat. To analyse the effect of each process step on the microstructure, specimens were extracted from cladded, forged and heat treated components and investigated by means of metallographic analysis and hardness measurements. The results demonstrate that cladded workpieces were successfully formed to complex toothed parts without any defects. The hot forming process has a positive impact on the welded layer and the interface zone by grain refinement and the associated improved mechanical properties. The required hardness values at the tooth flanks were achieved by the integrated heat treatment".
title: Autonomous Topography Detection and Traversal for an Inspection Robot Within the Beamline of Particle Accelerators

description: Particle accelerators feature ultra-high vacuum pipe systems with unique topography, i.e. with a multitude of different vacuum chambers of varying dimensions and varying pipe apertures. In order to be able to examine the interior of the entire vacuum system, even those parts which are not accessible without disassembling large parts of the accelerator, a semi-autonomous robot is being developed which shall traverse and visually inspect the vacuum system of particle accelerators. We present a generic concept based on distance sensors for the inspection robot to detect steps between vacuum chambers and gaps in the beamline. Movement strategies to autonomously overcome these basic obstacles are introduced. For evaluation we use simulations of ideal environments with flat surfaces as well as realistic beam pipe environments of the SIS100 particle accelerator. Additionally, a prototype of our robot concept confirms the implementation of all maneuvers. Results show that obstacles of previously unknown dimensions can be detected and reliably traversed.

description: The study of planetary nebulae (PNe) offers the opportunity of evaluating the efficiency of the dust production mechanism during the very late asymptotic giant branch (AGB) phases. We study the relationship between the properties of PNe, particularly the gas and dust content, with the mass and metallicity of the progenitor stars, to understand how dust production works in the late AGB phases, and to shed new light on the physical processes occurring to the stars and the material in their surroundings since the departure from the AGB until the PN phase. We consider a sample of 9 PNe in the Large Magellanic Cloud, 7 out of which characterized by the presence of carbonaceous dust, the remaining 2 with silicates. For these stars the masses and the metallicity of the progenitor stars were estimated. We combine results from stellar evolution and dust formation modelling with those coming from the analysis of the spectral energy distribution, to find the relation between the dust and gas mass of the PNe considered and the The physical properties of carbon-rich PNe are influenced by the mass of the progenitor star. Specifically, the dust-to-gas ratio in the nebula increases from 5x10^{-4}to 6x10^{-3} as the progenitor star's mass increases from approximately 0.9Msun to 2Msun. This change is partly influenced by the effective temperature of the PNe, and it occurs because higher-mass carbon stars are more efficient at producing dust. Consequently, as the progenitor's mass increases, the gas mass of the PNe decreases, since the larger amounts of dust lead to greater effects from radiation pressure, which pushes the gas outwards. No meaningful conclusions can be drawn by the study of the PNe with silicate-type dust, because the sub-sample is made up of 2 PNe only, one of which is almost dust-free.

Origin of Strong Two-Magnon Scattering in Heavy Metal/Ferromagnet/Oxide Heterostructures

description: We experimentally investigate the origin of the two-magnon scattering (TMS) in heavy-metal (HM)/ferromagnet (FM)/oxide heterostructures (FM = Co, Ni81Fe19, or Fe60Co20B20) by varying the materials located above and below the FM layers. We show that strong TMS in HM/FM/oxide systems arises primarily at the HM/FM interface and increases with the strength of interfacial spin-orbit coupling and magnetic roughness at this interface. TMS at the FM/oxide interface is relatively weak, even in systems where spin-orbit coupling at this interface generates strong interfacial magnetic anisotropy. We also suggest that the spin-current-induced excitation of non-uniform short-wavelength magnon at the HM/FM interface may function as a mechanism of spin memory loss for the spin-orbit torque exerted on the uniform mode.
