Multi-wavelength study of 14 000 star-forming galaxies from the Sloan Digital Sky Survey

We studied a large sample of 14000 dwarf star-forming galaxies with strong emission lines. These low-metallicity galaxies with oxygen abundances of 12+logO/H 7.4 ‐ 8.5 are selected from the Sloan Digital Sky Survey (SDSS) and distributed in the redshift range of z 0 ‐ 0.6. We modelled spectral energy distributions (SED) of all galaxies which were based on the SDSS spectra in the visible range of 0.38 m ‐ 0.92 m and included both the stellar and ionised gas emission. These SEDs were extrapolated to the UV and mid-infrared ranges to cover the wavelength range of 0.1 m ‐ 22 m. The SDSS spectroscopic data were supplemented by photometric data from the GALEX, SDSS, 2MASS, WISE, IRAS, and NVSS all-sky surveys. Using these data, we derived global characteristics of the galaxies, such as their element abundances, luminosities, and stellar masses. The luminosities and stellar masses range within the sample over 5 orders of magnitude, thereby linking low-mass and low-luminosity blue compact dwarf (BCD) galaxies to luminous galaxies, which are similar to high-redshift Lyman-break galaxies (LBGs). It was found that the luminosity L(H ) of the H emission line, a characteristic of the youngest stellar population with an age of a few Myr, is correlated with luminosities in other wavelength ranges. This implies that the most recent burst of star formation makes a significant contribution to the emission in the visible range and dominates in other wavelength ranges. It was also found that the contribution of the young population to the galaxy luminosity is higher for galaxies with higher L(H ) and higher equivalent widths EW(H ). We found 20 galaxies with very red WISE mid-infrared m(3.4 m) ‐ m(4.6 m) colour ( 2 mag), which suggests the important contribution of the hot (with a temperature of several hundred degree) dust emission in these galaxies. Our analysis of the balance between the luminosity in the WISE bands that covered a wavelength range of 3.4 m ‐ 22 m and the luminosity of the emission absorbed at shorter wavelengths showed that the luminosity of the hot dust emission is increased with increasing L(H ) and EW(H ). We demonstrated that the emission emerging from young star-forming regions is the dominant dust-heating source for temperatures to several hundred degrees in the sample star-forming galaxies.
Doum fruit (Hyphaene thebaica (L.) Mart.) supplementation improves glycemic index of wheat flour bread in apparent healthy volunteers

The increasing demand for plant-based enriched diet has encouraged the food industry to produce fiber-supplemented products such as composite breads using locally available plants products. In the present study, composite breads from doum (Hyphaene thebaica Mart.) fruit and wheat flours were produced. Control bread (0% doum fruit) and four different composite breads (10%, 20%, 30% and 40% doum fruit) were produced. The physical properties, sensory evaluation, shelf-life, proximate composition, antinutrients content and glycemic index (GI) of the composite breads were investigated. Supplementation of wheat bread with doum fruit improved the nutritional content by increasing the fiber and mineral contents with reduction in phytate content. The composite bread, especially at 40% doum fruit inclusion was moderately accepted by the product testing panels. Inclusion of doum fruit further improved the shelf-life of the composite breads at both ambient and refrigerated temperatures. Similarly, the GI was observed to improve with doum fruit inclusion at all the concentration used. Conclusively, inclusion of doum fruit to the wheat flour produced composite breads with improved physical and nutrients quality with moderate overall acceptability and lower GI.
Towards a successful transition to work - which employability factors contribute to early career success?

ABSTRACT The transition from university to working life is a challenging phase for graduates. The focus in the present longitudinal study is on employability factors and their association with this transition and with early career success. The participants were 43 graduates who were interviewed at the time of their graduation and filled in a follow-up questionnaire three years later. The data were analysed using qualitative content analysis. The results revealed five employability factors relating early career success: (1) career plans and goals, (2) perceived competences related to the degree, (3) self-efficacy beliefs, (4) activity and (5) work experience and networks. Three transition groups emerged based on the differences in employability factors and career success, which we labelled smooth transition, progressive transition and a rocky road. The results revealed individual variation in employability factors and in the kind of challenges these graduates encountered in the transition phase and in their early career. An awareness of the ways in which graduates differ could help educators to develop practises that better support students and graduates in the transition to working life. These findings highlight the importance of active career planning during one’s studies.
Is Increasing Age Associated with Higher Rates of Intercostal Arteries Vulnerable to Laceration? A Point of Care Ultrasound Study

Ultrasound-guided pre-procedural planning decreases complications from bedside thoracentesis. Although rare, intercostal artery (ICA) laceration is a serious complication that occurs when vulnerable intercostal arteries (VICA) are no longer protected by the superior rib. We sought to determine if increasing patient age is associated with greater odds of encountering a VICA. Randomly selected in-patients underwent pre-procedural planning for a mock posterior bedside thoracentesis. ICAs were categorized as vulnerable if they were visible within the corresponding intercostal space (ICS). We recorded where the VICA entered and exited the ICS as well as its unshielded length. A total of 40 patients (20 male) were enrolled and 240 ICS (6 ICS per patient) were scanned. Within this cohort, 25% of patients were noted to have at least one VICA. We could not demonstrate any relationship between the patient’s age or location of the ICS, with the odds of encountering a VICA (odds ratio (OR) = 1.0, p = 0.76; OR = 0.85, p = 0.27, respectively). Given the haphazard nature of VICA distribution and poor outcomes associated with inadvertent laceration, we recommend that ICA screening at the site of needle insertion be routinely performed prior to thoracentesis.
Quantitative and qualitative criteria for assessing gait speed in women aged 60–75 years – A pilot study

Introduction: The use of the Gait Speed (GS) test in clinical practice has been documented in many scientific studies. However, there is a lack of tools to use the aforementioned test for diagnosis and follow-up of changes in the process of health training in postmenopausal women. Having considered the foregoing, the main objective of this study was to develop quantitative and qualitative criteria to assess gait speed in women aged 60–75 years. Material and methods: Sixty women aged 60–75 years participated in the study. The structure of the gait speed rating scale was based on Zaciorski's model. The data collected during the GS test was analyzed. We developed quantitative and qualitative criteria to assess gait speed in women over the age of 60, which ranged from 1.25 m/s to 2.3 m/s. Results and conclusions: The scale presented in this study can constitute an effective tool to help estimate the level of gait speed in women aged 60–75 years, which is particularly important in coaching practice during diagnostics and programming of physical activity.
The progenitors of Type Ia supernovae with long delay times

The nature of the progenitors of Type Ia supernovae (SNe Ia) is still unclear. In this paper, by considering the effect of the instability of accretion disc on the evolution of white dwarf (WD) binaries, we performed binary evolution calculations for about 2400 close WD binaries, in which a carbon-oxygen WD accretes material from a main-sequence (MS) star or a slightly evolved subgiant star (WD + MS channel), or a red-giant star (WD + RG channel) to increase its mass to the Chandrasekhar (Ch) mass limit. According to these calculations, we mapped out the initial parameters for SNe Ia in the orbital period-secondary mass (log P(i) - M(2)(i)) plane for various WD masses for these two channels, respectively. We confirm that WDs in the WD + MS channel with a mass as low as 0.61 M(circle dot) can accrete efficiently and reach the Ch limit, while the lowest WD mass for the WD + RG channel is 1.0 M(circle dot). We have implemented these results in a binary population synthesis study to obtain the SN Ia birthrates and the evolution of SN Ia birthrates with time for both a constant star formation rate and a single starburst. We find that the Galactic SN Ia birthrate from the WD + MS channel is similar to 1.8 x 10(-3) yr(-1) according to our standard model, which is higher than the previous results. However, similar to the previous studies, the birthrate from the WD + RG channel is still low (similar to 3 x 10(-5) yr(-1)). We also find that about one-third of SNe Ia from the WD + MS channel and all SNe Ia from the WD + RG channel can contribute to the old populations (greater than or similar to 1 Gyr) of SN Ia progenitors.
INTERACTING SUPERNOVAE AND SUPERNOVA IMPOSTORS: SN 2009ip, IS THIS THE END?

We report the results of a three-year-long dedicated monitoring campaign of a restless luminous blue variable (LBV) in NGC 7259. The object, named SN 2009ip, was observed photometrically and spectroscopically in the optical and near-infrared domains. We monitored a number of erupting episodes in the past few years, and increased the density of our observations during eruptive episodes. In this paper, we present the full historical data set from 2009 to 2012 with multi-wavelength dense coverage of the two high-luminosity events between 2012 August and September. We construct bolometric light curves and measure the total luminosities of these eruptive or explosive events. We label them the 2012a event (lasting ∼50 days) with a peak of 3 × 1041 erg s−1, and the 2012b event (14 day rise time, still ongoing) with a peak of 8 × 1042 erg s−1. The latter event reached an absolute R-band magnitude of about −18, comparable to that of a core-collapse supernova (SN). Our historical monitoring has detected high-velocity spectral features (∼13,000 km s−1) in 2011 September, one year before the current SN-like event. This implies that the detection of such high-velocity outflows cannot, conclusively, point to a core-collapse SN origin. We suggest that the initial peak in the 2012a event was unlikely to be due to a faint core-collapse SN. We propose that the high intrinsic luminosity of the latest peak, the variability history of SN 2009ip, and the detection of broad spectral lines indicative of high-velocity ejecta are consistent with a pulsational pair-instability event, and that the star may have survived the last outburst. The question of the survival of the LBV progenitor star and its future fate remain open issues, only to be answered with future monitoring of this historically unique explosion.
Emergent gravity: the BEC paradigm

We study selected aspects of quantum gravity phenomenology inspired by the gravitational analogy in Bose–Einstein condensates (BECs). We first review the basic ideas and formalism of analogue gravity in BECs, with particular emphasis on the possibility of simulating black holes. We stress that the dispersion relation in a BEC has a relativistic form in the hydrodynamic limit, and acquires non-relativistic, ‘superluminal’ modifications at high frequencies. This makes it a particularly interesting model for many scenarios of quantum gravity phenomenology which consider a possible violation of local Lorentz invariance at high energies. In particular, it allows the study of kinematical corrections that such quantum gravity scenarios could impose on general relativity.
The X-ray/UV absorber in NGC 4593

We present the results of a recent (March 2011) 160 ks Chandra-LETGS observation of the Seyfert galaxy NGC 4593, and the analysis of archival X-ray and UV spectra taken with XMM-Newton and HST/STIS in 2002. We find evidence of a multi-component warm absorber (WA) in the X-rays with four distinct ionisation degrees (logξ = 1.0, logξ = 1.7, logξ = 2.4, and logξ = 3.0) outflowing at several hundreds of km s −1 . In the UV we detect 15 kinematic components in the absorbers, blueshifted with respect to the systemic velocity of the source, ranging from−60 km s −1 to−1520 km s −1 . Although the predicted Civ and Nv column densities from the low-ionisation X-ray outflow are i n agreement with those measured for some components in the STIS spectrum, there are kinematic discrepancies that may prevent both the X-ray and UV absorbers from originating in the same intervening gas. We derive upper limits on the location of the absorbers finding t hat the high-ionisation gas lie within∼ 6− 29 pc from the central ionising source, while the low-ionisation gas is located at several hundreds of pc. This is consistent with our line of si ght passing through different parts of a stratified wind. The total kinetic energy of the outflows i njected into the surroundings of the host galaxy only accounts for a tiny fraction of the bolometric luminosity of the source and it is therefore unlikely that they may cause a significant impact in the interstellar medium of NGC 4593 in a given single episode of activity.
ON THE MECHANISM OF HARD X-RAY EMISSION FROM MAGNETARS

Persistent activity of magnetars is associated with electric discharge that continually injects relativistic particles into the magnetosphere. Large active magnetic loops around magnetars must be filled with outflowing particles that interact with radiation via resonant scattering and spawn electron–positron pairs. The outflow energy is processed into copious e± until the plasma enters outer parts of the loop where the magnetic field is reduced below 1013 G. In the outer zone, photons scattered by the outflow do not convert to e± pairs and the outflow radiates its energy away. The escaping radiation forms a distinct hard X-ray peak in the magnetar spectrum. It has the following features: (1) its luminosity L = 1035–1036 erg s−1 can easily exceed the thermal luminosity from the magnetar surface, (2) its spectrum extends from 10 keV to the MeV band with a hard spectral slope, which depends on the object inclination to the line of sight, (3) the anisotropic hard X-ray emission exhibits strong pulsations as the magnetar spins, (4) the emission spectrum typically peaks around 1 MeV, but the peak position significantly oscillates with the spin period, (5) the emission is dominated by the extraordinary polarization mode at photon energies below ∼1 MeV, and (6) the decelerated pairs accumulate and annihilate at the top of the magnetic loop, and emit the 511 keV line with luminosity Lann ∼ 0.1 L. Features (1)–(3) agree with available data; (4)–(6) can be tested by future observations.
A 3-D Space-Time-Frequency Non-Stationary Model for Low-Altitude UAV mmWave and Massive MIMO Aerial Fading Channels

In this article, a 3-D geometry-based stochastic model (GBSM) is proposed for millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) unmanned aerial vehicle (UAV) channels. The proposed model is the first mmWave massive MIMO UAV two-cylinder GBSM that enables to jointly model the channel space-time-frequency non-stationarity by a novel variable parameter-based method. In this novel method, key parameters of UAV channels are assumed to vary in space, time, and frequency domains, and the effect of the unique UAV-related parameters is further taken into account, such as the UAV’s altitude, velocity, and moving directions. Based on the proposed model, some statistical properties are derived, including the time-variant transfer function (TVTF), space-time-frequency correlation function (STF-CF), Doppler power spectral density (PSD), and the standard deviation of Doppler frequency on antenna arrays. Simulation results show that the channel non-stationarity in space, time, and frequency domains can be captured, and the aforementioned UAV channel-related parameters have a great impact on channel statistics. Finally, the utility of the proposed model is validated by the excellent agreement between simulation results and measurements.
Association between Plasma Omega-3 and Handgrip Strength According to Glycohemoglobin Levels in Older Adults: Results from NHANES 2011–2012

Background: Low muscle strength is a predictor of mortality in older adults. Although the evidence concerning hyperglycemia is limited, evidence shows that omega-3 (ω-3) intake may be positively associated with muscle strength. However, the association between plasma ω-3 and muscle strength in older adults according to glycohemoglobin (HbA1c) levels has not yet been investigated. Objective: To evaluate whether plasma ω-3 levels are associated with handgrip strength in individuals over 50 years according to HbA1c levels. Methods: This cross-sectional study included 950 older adults (50–85 years) from NHANES 2011–2012. Linear regression analysis was performed to evaluate the association between plasma ω-3 and handgrip strength in individuals with elevated (≥5.7%) or normal HbA1c levels after adjustments for confounders. Results: Total plasma ω-3, docosahexaenoic acid, eicosapentaenoic acid and alpha-linolenic acid were not associated with handgrip strength in older adults regardless of HbA1c levels. Conclusion: Plasma ω-3 levels are not associated with handgrip strength in individuals over 50 years old independent of HbA1c levels.
EXPLORING THE LOW-MASS END OF THE MBH–σ* RELATION WITH ACTIVE GALAXIES

We present new measurements of stellar velocity dispersions, using spectra obtained with the Keck Echellette Spectrograph and Imager (ESI) and the Magellan Echellette (MagE), for 76 Seyfert 1 galaxies from the recent catalog of Greene & Ho. These objects were selected from the Sloan Digital Sky Survey (SDSS) to have estimated black hole (BH) masses below 2 × 106 M☉. Combining our results with previous ESI observations of similar objects, we obtain an expanded sample of 93 galaxies and examine the relation between BH mass and velocity dispersion (the MBH–σ* relation) for active galaxies with low BH masses. The low-mass active galaxies tend to follow the extrapolation of the MBH–σ* relation of inactive galaxies. Including results for active galaxies of higher BH mass from the literature, we find a zero point α = 7.68 ± 0.08 and slope of β = 3.32 ± 0.22 for the MBH–σ* relation (in the form log MBH = α + βlog (σ*/200 km s−1)), with intrinsic scatter of 0.46 ± 0.03 dex. This result is consistent, within the uncertainties, with the slope of the MBH–σ* relation for reverberation-mapped active galaxies with BH masses from 106 to 109 M☉. For the subset of our sample having morphological information from Hubble Space Telescope images, we examine the slope of the MBH–σ* relation separately for subsamples of barred and unbarred host galaxies, and find no significant evidence for a difference in slope. We do find a mild offset between low-inclination and high-inclination disk galaxies, such that more highly inclined galaxies tend to have larger σ* at a given value of BH mass, presumably due to the contribution of disk rotation within the spectroscopic aperture. We also find that the velocity dispersion of the ionized gas, measured from narrow emission lines including [N ii] λ6583, [S ii] λλ6716, 6731, and the core of [O iii] λ5007 (with the blueshifted wing removed), trace the stellar velocity dispersion well for this large sample of low-mass Seyfert 1 galaxies.
TOWARDS RELIABLE DECISION-MAKING IN THE GREEN URBAN TRANSPORT DOMAIN

Operational research is a scientific discipline related to the decision theory that allows determining solutions for specific problems related to, for example, widely understood transport. Increasingly popular in this field are issues related to the domain of the green urban transport. In order to support the decision-making process in this area, methods of multi-criteria decision analysis (MCDA) are used more and more often. However, if we solve a specific problem using different MCDA methods, we get different rankings, as each method has a different methodological basis. Therefore, the challenge is how to make a reliable decision. This paper presents a numerical example from the green urban transport domain, which is solved by six different MCDA methods that return a complete ranking. We measure the similarity of these rankings using coefficients rw and WS, and then we propose a simple way of determining a compromise solution. The obtained compromise ranking is guaranteed to be the best match to the selected MCDA methods' rankings, which is proved in the paper. Finally, possible directions for further development work are identified.
Mycobacterium avium subsp. paratuberculosis Infected Cows Reveal Divergent Immune Response in Bovine Peripheral Blood Derived Lymphocyte Proteome

Bovine paratuberculosis is a serious chronic disease of the gastrointestinal tract that causes economic losses and dramatically affects animal health in livestock. The underlying infectious agent, Mycobacterium avium subspecies paratuberculosis (MAP), cannot reliably be detected by standard diagnostic tests due to the long asymptomatic disease stage. The aim of this study was to detect proteomic changes in peripheral blood mononuclear cells (PBMC) from cows of the same herd with different MAP infection status after co-incubation with viable MAP in vitro using label-free LC-MS/MS. In our proteomic discovery experiment, we detected 2631 differentially regulated proteins between cows with negative MAP infection status (so-called MAP-resistant cows) and cows with positive MAP infection status (so-called persistently MAP-infected cows). In MAP-resistant cows, we detected enriched immune-related signaling pathways for TLR2 and MHC class II component proteins, among others, indicating a successful defensive immune response of the cows to MAP. In contrast, persistently MAP-infected cows were not directly enriched in immune-related signaling pathways associated with ITGA2B and KCNMA1, among others. The introduction of these distinct immune responses contributes to a better understanding of the bovine immune response and mechanisms of susceptibility to MAP.
The Movement of Indonesia’s Foreign Exchange Rates and Other Macroeconomic Variables to Its Stock Market Volatility in a Pandemic Setting

This paper aims to examine the impact of foreign exchange rates on Indonesia’s composite stock index, the JKSE. To perfect the analysis, several other macroeconomic variables such as interest rates, oil prices, gold prices, as well as inflation rates were also added as proposed by preceding research. COVID-19 new infection cases were added as a moderating variable to test whether it can strengthen or weaken the correlation of each macroeconomic variable tested against the stock market. The parameter of this study is specifically focused on Indonesia to complete the lack of sufficient research conducted for the same topic and/or in the same setting. The study found all the macroeconomic variables tested in the analysis concurrently influence Indonesia’s stock market index. When each macroeconomic was tested separately, the test results found that although the direction of the impact varies, all the variables except for gold price were found to have a significant impact on the stock market in Indonesia. The moderating variable, COVID-19, was also found to have a notable influence on substantiating the impact of all the correlations tested except in moderating for exchange rates and oil price.
