Sleep disorders in polycystic ovary syndrome: influence of obesity and hyperandrogenism.

OBJECTIVE This study aims to evaluate the sleep of subjects with polycystic ovary syndrome (PCOS), with and without hyperandrogenism, in comparison with a healthy control group and examine the effects of hyperandrogenism and obesity on sleep parameters. METHODS A total of 44 volunteers were recruited to participate in the study. Clinical, biochemical and polysomnographic parameters were used to diagnose PCOS and hyperandrogenism. The evaluation of sleep quality was made using validated questionnaires and polysomnography test. The frequency of obstructive sleep apnea was also compared between the groups. RESULTS The study revealed that women with PCOS presented poorer subjective sleep quality, increased incidence of snoring and a higher risk of obstructive sleep apnea, based on the Berlin questionnaire. Also, after adjusting for body mass index, PCOS subjects had rapid eye movement (REM) time lower than those in the control group. PCOS women versus those without hyperandrogenism did not differ on any sleep measurement. Women with obstructive sleep apnea were only diagnosed in the PCOS group. CONCLUSIONS Our results indicate that PCOS impairs subjective sleep quality, as well as objective sleep quality, due to a reduction in REM sleep stage time in women diagnosed with the syndrome. Obesity affected sleep-related parameters but hyperandrogenism had no effect. Only the PCOS group had obstructive sleep apnea diagnosis.
Assessment of Anxiety Levels in Children Receiving Dental Treatment Using Rubber Dam- A Randomized Control Trial

Isolation is the major thing in the quality of treatment. But often clinicians consider rubber dam use can cause anxiety and fear evoking stimuli that may hamper their rapport with the child and thereby affect the quality of treatment. This creates a reluctance among practitioners to use rubber dams in the pediatric population.The aim of the study was to assess the anxiety levels in children in the age group of 6 to 10 years undergoing dental treatment with or without a rubber dam using the Animoji scale. This study was conducted on 48 children in the age group of 6 - 10 years, divided into two groups: group 1 (cotton roll isolation) and group 2 (rubber dam isolation). Anxiety levels were assessed using an animoji (animated emoji) scale which has a scale of score 1 to score 5 (very happy to very unhappy). The obtained data were statistically analyzed using SPSS(Statistical Package for Social Sciences) Version 24.0 (IBM Corporation, Chicago, USA). Descriptive and analytical statistics were done. The independent t-test was performed to know the differences between the two groups.The result proved that by comparing group 1 and group 2 there was no statistically significant difference between the two different groups p>0.05. This study concludes that the use of rubber dams does not create a significant rise in anxiety levels in children. Thus considering the advantages of rubber dams they should be used in Pediatric dentistry in an attempt to provide quality dental treatment for children.
Winds can ‘blow up’ AGN accretion disc sizes

Recent multi-band variability studies have revealed that active galactic nucleus (AGN) accretion disc sizes are generally larger than the predictions of the classical thin disc by a factor of $2\sim 3$. This hints at some missing key ingredient in the classical thin disc theory: here, we propose an accretion disc wind. For a given bolometric luminosity, in the outer part of an accretion disc, the effective temperature in the wind case is higher than that in the no-wind one; meanwhile, the radial temperature profile of the wind case is shallower than the no-wind one. In presence of winds, for a given band, blackbody emission from large radii can contribute more to the observed luminosity than the no-wind case. Therefore, the disc sizes of the wind case can be larger than those of the no-wind case. We demonstrate that a model with the accretion rate scaling as $\dot{M}_0 (R/R_{\mathrm{S}})^{\beta}$ (i.e., the accretion rate declines with decreasing radius due to winds) can match both the inter-band time lags and the spectral energy distribution of NGC 5548. Our model can also explain the inter-band time lags of other sources. Therefore, our model can help decipher current and future continuum reverberation mapping observations.
OAO/MITSuME Photometry of Dwarf Novae. II. HV Virginis and OT J012059.6+325545

We report on multicolor photometry of WZ Sge-type dwarf novae, HV Vir and OT J012059.6+325545 during superoutbursts. These systems show early superhumps with the mean periods of 0.057093(45) d for HV Vir and 0.057147(15) d for OT J012059.6+325545, respectively. The observed early superhumps showed a common feature that the brightness minima correspond to the bluest peaks in color variations, which may be a ubiquitous phenomenon among early superhumps of WZ Sge-type dwarf novae. We confirmed that amplitudes of early superhumps depend on wavelength: amplitudes with longer bandpass filters show larger values. This indicates that the light source of early superhumps is generated at the outer region of the vertically-extended accretion disk. On the other hand, amplitudes of ordinary superhumps are likely to be independent of wavelength. This implies that the superhump light source is geometrically thin. We also examined color variations of ordinary superhumps and found that the bluest peaks in $g'-I_{\rm c}$ tend to coincide with the brightness minima, particularily in stage B superhumps. This may reflect that the pressure effect plays a dominant role during stage B superhumps.
On the propagation of gravitational waves in a ΛCDM universe

We study here how the presence of non-zero matter density and a cosmological constant could affect the observation of gravitational waves in pulsar timing arrays. Conventionally, the effect of matter and cosmological constant is included by considering the redshift in frequency due to the expansion. However, there is an additional interesting effect due to the change of coordinates from the ones describing the geometry of the region where waves are produced to the ones used to measure the pulsar timing residuals. This change of coordinates is unavoidable as the strong gravitational field in a black hole merger distorts clocks and rules. Harmonic waves produced in such a merger become anharmonic when detected by a cosmological observer. The effect is tiny but appears to be nevertheless observable for the type of gravitational waves to which pulsar timing arrays are sensitive and for the favoured values of the cosmological parameters.

Informative Text Learning Through Processual Models to Improve Reading Comprehension Skills

This study looked at how teaching informative text structures using a processual paradigm affected the reading comprehension abilities of fourth-graders. An experimental model with pre-test-post-test control groups was used in the research's design. The study's study group was made up of 62 fourth-graders who attended a public school in the Turkish province of Konya during the 2020–2021 academic year. For ten weeks, the experimental group taught the informative texts using the processual paradigm, whereas the control group used the Turkish course's curriculum. The Reading Comprehension Test and the Awareness Test of Informative Text Structures were utilized as data gathering instruments in the study. The study's data were analyzed using the following methods: mean, standard deviation, unpaired t-test, and one-way analysis of variance. The study's findings showed that the experimental group, which had been taught informative texts using a processual paradigm, had significantly lower reading comprehension levels and less understanding of the structures of those texts.
Temporal slow-growth formulation for direct numerical simulation of compressible wall-bounded flows

A new slow growth formulation for DNS of wall-bounded turbulent flow is developed and demonstrated to enable extension of slow growth modeling concepts to complex boundary layer flows. As in previous slow growth approaches, the formulation assumes scale separation between the fast scales of turbulence and the slow evolution of statistics such as the mean flow. This separation enables the development of approaches where the fast scales of turbulence are directly simulated while the forcing provided by the slow evolution is modeled. The resulting model admits periodic boundary conditions in the streamwise direction, which avoids the need for extremely long domains and complex inflow conditions that typically accompany spatially developing simulations. Further, it enables the use of efficient Fourier numerics. Unlike previous approaches, the present approach is based on a temporally evolving boundary layer and is specifically tailored to give results for calibration and validation of RANS turbulence models. The use of a temporal homogenization simplifies the modeling, enabling straightforward extension to flows with complicating features, including cold and blowing walls. To generate data useful for calibration and validation of RANS models, special care is taken to ensure that the mean slow growth forcing is closed in terms of the mean and other quantities that appear in standard RANS models, ensuring that there is no confounding between typical RANS closures and additional closures required for the slow growth problem. The performance of the method is demonstrated on two problems: an essentially incompressible, zero-pressure-gradient boundary layer and a transonic boundary layer over a cooled wall with wall transpiration.
Monitoring AGNs with Hβ Asymmetry. I. First Results: Velocity-resolved Reverberation Mapping

We have started a long-term reverberation mapping (RM) project using the Wyoming Infrared Observatory 2.3 m telescope titled “Monitoring AGNs with Hβ Asymmetry” (MAHA). The motivations of the project are to explore the geometry and kinematics of the gas responsible for complex Hβ emission-line profiles, ideally leading to an understanding of the structures and origins of the broad-line region (BLR). Furthermore, such a project provides the opportunity to search for evidence of close binary supermassive black holes. We describe MAHA and report initial results from our first campaign, from 2016 December to 2017 May, highlighting velocity-resolved time lags for four active galactic nuclei (AGNs) with asymmetric Hβ lines. We find that 3C 120, Ark 120, and Mrk 6 display complex features different from the simple signatures expected for pure outflow, inflow, or a Keplerian disk. While three of the objects have been previously reverberation mapped, including velocity-resolved time lags in the cases of 3C 120 and Mrk 6, we report a time lag and corresponding black hole mass measurement for SBS 1518+593 for the first time. Furthermore, SBS 1518+593, the least asymmetric of the four, does show velocity-resolved time lags characteristic of a Keplerian disk or virialized motion more generally. Also, the velocity-resolved time lags of 3C 120 have significantly changed since previously observed, indicating an evolution of its BLR structure. Future analyses of the data for these objects and others in MAHA will explore the full diversity of Hβ lines and the physics of AGN BLRs.
Profitability, Company Size, Financial Leverage, and Dividend Payout Ratio Influencing Income Smoothing Practices

This study examines and analyzes the effect of profitability, company size, financial leverage, and dividend payout ratio on income smoothing practices. The population used in this study are mining companies listed on the Indonesia Stock Exchange (IDX) for the 2015-2018 period. This study uses secondary data with a sample of 10 companies selected by purposive sampling method. Data analysis was performed using statistics with SPSS 21 tools. Based on the data analysis results using the t-test, it was known that partially profitability, company size, financial leverage, and dividend payout ratio did not significantly affect income smoothing practices. Based on the results of data analysis using the F test, it is known that simultaneously profitability, company size, financial leverage, and dividend payout ratio do not have a significant effect on income smoothing practices.
Chern-Simons Holography: Boundary Conditions, Contractions and Double Extensions for a Journey Beyond Anti-de Sitter

In this thesis Chern-Simons theories based on Lie algebras with invariant metric are constructed. It is discussed how contractions lead systematically to (higher spin) kinematical algebras of, e.g., Poincar\'e, Galilei and Carroll type and how they can be extended to permit an invariant metric. A new generalization of the In\"on\"u-Wigner contractions explains why the invariant metric stays nondegenerate in the ultra-relativistic limes to the Carroll algebras. Since asymptotic symmetries give a first glance of possible dual theories consistent boundary conditions for Lifshitz and null-warped higher spins and Carroll gravity are provided. Finally, selected higher spin generalizations will be examined on the linear level.

The origin of the ‘blue tilt’ of globular cluster populations in the E-MOSAICS simulations

The metal-poor sub-population of globular cluster (GC) systems exhibits a correlation between the GC average colour and luminosity, especially in those systems associated with massive elliptical galaxies. More luminous (more massive) GCs are typically redder and hence more metal-rich. This 'blue tilt' is often interpreted as a mass-metallicity relation stemming from GC self-enrichment, whereby more massive GCs retain a greater fraction of the enriched gas ejected by their evolving stars, fostering the formation of more metal-rich secondary generations. We examine the E-MOSAICS simulations of the formation and evolution of galaxies and their GC populations, and find that their GCs exhibit a colour-luminosity relation similar to that observed in local galaxies, without the need to invoke mass-dependent self-enrichment. We find that the blue tilt is most appropriately interpreted as a dearth of massive, metal-poor GCs: the formation of massive GCs requires high interstellar gas surface densities, conditions that are most commonly fostered by the most massive, and hence most metal rich, galaxies, at the peak epoch of GC formation. The blue tilt is therefore a consequence of the intimate coupling between the small-scale physics of GC formation and the evolving properties of interstellar gas hosted by hierarchically-assembling galaxies.
Ultraluminous starbursts in major mergers

We use numerical simulation to investigate the triggering of starbursts in merging disk galaxies. The properties of the merger-driven starbursts are sensitive to the structure of the progenitor galaxies; specifically, to the amount of material in a dense central bulge. Galaxies without bulges develop bars shortly after their first close passage, driving significant gas inflow and subsequent starbursts in the centers of the galaxies. These starbursts significantly deplete the star-forming gas, so that only relatively weak starbursts arise during the final merger. By contrast, models of galaxies with central bulges show that a bulge acts to stabilize the galaxies against inflow and starbursts until the galaxies actually merge. At this time, strong dissipation leads to the formation of a massive central gas mass and an ensuing star-formation rate two orders of magnitude greater than that in our isolated disk models. These starbursts are very short in duration, typically approximately 50 Myr, suggesting that the rarity of ultraluminous infrared galaxies is a result of their being in a very short evolutionary phase, rather than special and rare formation conditions. The fact that these mergers display many of the properties of ultraluminous infrared galaxies--tidal features, double nuclei, massive compact gas concentrations, and extreme levels of starburst activity--suggets that merger-driven starbursts can explain the emission from many ultraluminous infrared galaxies without an active nucleus.
Thermally activated laterite soil as an adsorbent for phosphate and fluoride removal from contaminated water

The present study examines the efficiency of thermal-activated laterite soil in different grain sizes as an adsorbent for removing phosphate and fluoride ions from contaminated water under laboratory conditions. The fresh laterite was collected from the inner layers of the weathering profile by auger drilling method. Collected soil samples were air-dried to remove the excess mois-ture content. Air-dried soil was crushed to prepare powdered material (2 and 0.5 mm). Thermally activated soil samples were prepared by heating the laterite at 100°C, 200°C, 300°C, and 400°C for 3 h in a muffle furnace. Adsorption conditions of phosphate and fluoride ions for the soil samples were determined by batch experiments conducted at room temperature and natural pH. Based on the results of studies, 300°C and 400°C (2 and 0.5 mm gran sizes) thermal-activated laterite soil proved to be an effective adsorbent and had higher removal capacities. The phosphate and fluoride removal efficiencies of 300°C activated 0.5 mm laterite soil were 96.46% ± 0.63% and 99.33% ± 0.40%, respectively. Phosphate and fluoride removal efficiencies from 300°C activated 2 mm laterite soil were 92.72% ± 0.60% and 96.80% ± 0.60%, respectively. In contrast, 20 min for 2 mm grain size and 10 min for 0.5 mm were the optimal contact times for maximum phosphate and fluoride ion removal. Phosphate removal efficiency was 91.93% ± 0.24% and fluoride removal efficiency was 92.67% ± 0.24% after 10 min at 300°C, 0.5 mm laterite soil. At 20 min, the phosphate removal efficiency in 2 mm of 300°C soil was 77.88% ± 1.30%, and the fluoride removal efficiency was 81.60% ± 0.31%. 0.75 g of laterite soil was identified as the optimum soil dosage for both grain sizes of phosphate and fluoride removal. The removal efficiency of phosphate and fluoride from 0.75 g, 300°C 0.5 mm laterite soil were 90.08% ± 0.30% and 93.53% ± 0.30%, respectively. Phosphate and fluoride removal efficiency from 0.75 g, 300°C 2 mm laterite soil were 84.88% ± 0.10% and 79.33% ± 0.10%, respectively. The results concluded that the percentage of removal rises with the increase in temperature. In contrast, results revealed that thermal-activated laterite soil has a strong ability to remove phosphate and fluoride from water.

Ice Water Path-Optical Depth Relationships for Cirrus and Deep Stratiform Ice Cloud Layers.

Abstract Particle size distribution (PSD) and particle shape information collected during Lagrangian spiral descents and balloon ascents through 13 midlatitude and 6 tropical ice clouds are analyzed to investigate the relationship between cloud optical depth in visible wavelengths (τυ) and the ice water path (IWP). Although this sample size is small, it is far larger than the number of samples used in earlier studies and has the added benefit that it contains data from the top to the bottom of cloud layers, averaging 3 km in geometrical thickness. Furthermore, the observed particle shape and habit information are used directly in the investigation, rather than assuming that the habits are one of a number of pristine types. These observations apply to midlatitude clouds in the temperature range from −65° to −20°C, with τυ between 0.5 and 7, and estimated radar reflectivities primarily in the range from −20 to 5 dBZe (at a frequency of 35 GHz), with some observations extending down to −45 dBZe.

Global acoustic oscillations on Alpha Bootis

A two-week time series of precise radial velocity measurements of Alpha Bootis (Arcturus) covering 7-8 hr per night is reported. The radial barycentric velocity of the star is found to be -5021 + or - 5 m/s. When data from the whole run are jointly analyzed, several equispaced peaks in the frequency appear in the range of a few microhertz, the highest amplitude being some 60 m/s at 4.3 microhertz. The most probable frequency spacing seems to be 50 microhertz, while the frequency cutoff is around 80 microhertz. 31 refs.
