Al-Rasm al-'Uthmānī fī al-Muṣḥaf al-mi‘yārī al-Indūnīsī ‘inda al-Dānī wa Abī Dāwud
Authors: Madzkur Zainal Arifin 
Published: April 2020

This article aims to find a scientific argument for the differences in rasm ‘Uthmānī between Indonesian’s muṣḥaf and Madinah’s muṣḥaf. Some people claim that rasm ‘Uthmānī of the Madinah’s muṣḥaf is the most proper compared to the Indonesian’s muṣḥaf. Through the comparison of the differences in both muṣḥafs based on the two books of al-Muqni‘ by al-Dānī and Mukhtaṣar al-tabyīn by Abū Dāwud Sulaymān, both have basics of similarity. The difference in the writing of rasm ‘Uthmānī in the Indonesian’s muṣḥaf and the Madinah’s muṣḥaf in general only lies in the difference in their affiliation in the two major schools in this discipline that were written in the 5th century Hijri by al-Dānī and Abū Dāwud. This article proves that differences in rasm ‘Uthmānī are common in terms of transmission, and the claim that the rasm of Madinah’s muṣḥaf is the most correct of rasm ‘Uthmānī is a mistake.

Abstract
In this paper, we present the first light curve synthesis and orbital period change analysis of nine contact binaries around the short-period limit. It is found that all these systems are W-subtype contact binaries. One of them is a medium contact system while the others are shallow contact ones. Four of them manifest obvious O’Connell effect explained by a dark spot or hot spot on one of the component stars. Third light was detected in three systems. By investigating orbital period variations, we found that four of the targets display a secular period decrease while the others exhibit a long-term period increase. The secular period decrease is more likely caused by angular-momentum loss while the long-term period increase is due to mass transfer from the less massive component to the more massive one. Based on the statistic of 19 ultrashort-period contact binaries with known orbital period changes, we found that seven of them display long-term decrease (three of them also exhibit cyclic variations), ten of them manifest long-term increase while two of them only show cyclic variation, and that most of them are shallow contact binaries supporting the long timescale angular-momentum loss theory suggested by Stepien. For the three deep contact systems, we found that they are probably triple systems. The tertiary companion plays an essential role during their formation and evolution.

Abstract
Following the success of the first mission, the High-Resolution Coronal Imager (Hi-C) was launched for a third time (Hi-C 2.1) on 2018 May 29 from the White Sands Missile Range, NM, USA. On this occasion, 329 s of 17.2 nm data of target active region AR 12712 were captured with a cadence of ≈4 s, and a plate scale of 0.″129 pixel−1. Using data captured by Hi-C 2.1 and co-aligned observations from SDO/AIA 17.1 nm, we investigate the widths of 49 coronal strands. We search for evidence of substructure within the strands that is not detected by AIA, and further consider whether these strands are fully resolved by Hi-C 2.1. With the aid of multi-scale Gaussian normalization, strands from a region of low emission that can only be visualized against the contrast of the darker, underlying moss are studied. A comparison is made between these low-emission strands and those from regions of higher emission within the target active region. It is found that Hi-C 2.1 can resolve individual strands as small as ≈202 km, though the more typical strand widths seen are ≈513 km. For coronal strands within the region of low emission, the most likely width is significantly narrower than the high-emission strands at ≈388 km. This places the low-emission coronal strands beneath the resolving capabilities of SDO/AIA, highlighting the need for a permanent solar observatory with the resolving power of Hi-C.
Prospects for Directly Imaging Young Giant Planets at Optical Wavelengths
Authors: Lacy Brianna , Burrows Adam 
Published: April 2020

Abstract
In this work, we investigate the properties of young giant planet spectra in the optical and suggest that future space-based direct imaging missions should be considering young planets as a valuable and informative science case. While young planets are dimmer in the optical than in the infrared, they can still be brighter in the optical than a mature planet of similar mass. Therefore, an instrument designed to characterize mature planets should also be suitable for high-precision photometric imaging and spectroscopy of young self-luminous planets in a wavelength range and at a contrast ratio not currently attainable from the ground. We identify known young self-luminous companions that are feasible targets for coronagraphic instrument on the Wide Field Infrared Survey Telescope (WFIRST-CGI) and compute spectra for them, including a treatment of scattering and reflected light at optical wavelengths. Using these results, we highlight potentially diagnostic spectral features that will be present in the WFIRST-CGI wavelengths. Expanding to direct imaging missions beyond WFIRST-CGI, we also use evolutionary models across a grid of masses and planet–star separations as inputs to compute spectra of hypothetical objects, exploring when reflected light may contribute to a degree comparable to that of thermal emission from the residual heat of formation.

Abstract
We present two years of Neutron star Interior Composition Explorer (NICER) X-ray observations of three energetic rotation-powered millisecond pulsars (MSPs): PSRs B1937+21, B1821−24, and J0218+4232. We fit Gaussians and Lorentzians to the pulse profiles for different energy sub-bands of the soft X-ray regime to measure the energy dependence of pulse separation and width. We find that the separation between pulse components of PSR J0218+4232 decreases with increasing energy at >3σ confidence. The 95% upper limit on pulse separation evolution for PSRs B1937+21 and B1821−24 is less than 2 milliperiods per keV. Our phase-resolved spectral results provide updated constraints on the non-thermal X-ray emission of these three pulsars. The photon indices of the modeled X-ray emission spectra for each pulse component of PSR B1937+21 are inconsistent with each other at the 90% confidence level, suggesting different emission origins for each pulse. We find that the PSR B1821−24 and PSR J0218+4232 emission spectra are invariant with phase at the 90% confidence level. We describe the implications of our profile and spectral results in the context of equatorial current sheet emission models for these three MSPs with non-thermal, magnetospheric X-ray emission.

Published: April 2020

Abstract
We analyzed the light curves of 1376 early-to-late, nearby M dwarfs to search for white-light flares using photometry from the All-Sky Automated Survey for Supernovae. We identified 480 M dwarfs with at least one potential flare employing a simple statistical algorithm that searches for sudden increases in V-band flux. After more detailed evaluation, we identified 62 individual flares on 62 stars. The event amplitudes range from

mag. Using classical flare models, we place lower limits on the flare energies and obtain V-band energies spanning

erg. The fraction of flaring stars increases with spectral type, and most flaring stars show moderate to strong Hα emission. Additionally, we find that 14 of the 62 flaring stars are rotational variables, and they have shorter rotation periods and stronger Hα emission than nonflaring rotational variable M dwarfs.
Time-resolved and Energy-resolved Polarizations of GRB Prompt Emission
Authors: Lan Mi-Xiang , Dai Zi-Gao 
Published: April 2020

Abstract
Besides light curves and spectra, polarization provides a different powerful tool of studying the gamma-ray burst (GRB) prompt phase. Compared with the time-integrated and energy-integrated polarization, time-resolved and energy-resolved polarization can deliver more physical information about the emitting region. Here we investigate time-resolved and energy-resolved polarization of GRB prompt emission using the synchrotron models. We find that the equal arrival time surface effect is very important in shaping the polarization degree (PD) curves when the physical conditions of the emitting region change violently with radius. Polarization properties are neither correlated with the spectral lag nor the peak energy evolution patterns. Polarization properties with a mixed magnetic field are very similar to those for a corresponding ordered magnetic field but the former has a smaller PD. The emission at the MeV peak can be highly polarized for a synchrotron model while it is unpolarized as predicted by a dissipative photosphere model. Future energy-resolved polarization observations can distinguish between these two models.

Abstract
The study of cluster post-starburst galaxies gives useful insights on the physical processes quenching the star formation in the most massive environments. Exploiting the Multi Unit Spectroscopic Explorer data of the GAs Stripping Phenomena in galaxies project, we characterize the quenching history of eight local cluster galaxies that were selected for not showing emission lines in their fiber spectra. We inspect the integrated colors, the Hβ rest-frame equivalent widths (EW), star-formation histories (SFHs), and luminosity-weighted age (LWA) maps finding no signs of current star formation throughout the disks of these early-spiral/S0 galaxies. All of them have been passive for at least 20 Myr, but their SF declined on different timescales. In most of them, the outskirts reached undetectable SFRs before the inner regions (“outside-in quenching”). Our sample includes three post-star-forming galaxies, two passive galaxies, and three galaxies with intermediate properties. The first population shows blue colors, deep Hβ in absorption (EW ≫ 2.8 Å), young ages (8.8 < log(LWA (yr)) < 9.2). Two of these galaxies show signs of a central SF enhancement before quenching. Passive galaxies have instead red colors, EW(Hβ) < 2.8 Å, ages in the range 9.2 < log(LWA (yr)) < 10. Finally, the other galaxies are most likely in transition between a post-star-forming and passive phase, as they quenched in an intermediate epoch and have not lost all of the star-forming features yet. The outside-in quenching, the morphology, and kinematics of the stellar component, along with the position of these galaxies within massive clusters (σ
cl = 550–950

km

) point to a scenario in which ram pressure stripping has removed the gas, leading to quenching. Only the three most massive galaxies might alternatively have entered the clusters already quenched. These galaxies are therefore at the final stage of the rapid evolution galaxies undergo when they enter the cluster environment.

Notre article décrit et analyse les activités éducatives d’un blogueur qui se consacre à la propagation de l’opéra classique. Cette analyse est une occasion de montrer les similitudes et les différences entre un blog et un forum de discussion, qui sont des applications Internet sociales très populaires. Ils servent de points de cristallisation pour des communautés virtuelles de nature différente. Le forum de discussion est une plate-forme pour la création d’une mini-communauté démocratique, rappelant la société civile , au sein de laquelle il est possible de cultiver les vertus civiques. Cependant, la communauté qui se forme autour du blog n’a plus un caractère démocratique, mais ressemble plus à un salon parisien de la fin du XVIII e siècle, dominé par l’autorité d’un maître	spirituel.

Thickness of the Retinal Nerve Fiber Layer, Macular Thickness, and Macular Volume in Patients With Strabismic Amblyopia
Authors: Altintas Özgül , Yüksel Nursen , Özkan Berna , Çaglar Yusuf 
Published: April 2020

Objective:
To compare the thickness of the retinal nerve fiber layer (RNFL), the macular volume, and the macular thickness of the amblyopic eye with those of the non-amblyopic eye in patients with unilateral strabismic amblyopia using optical coherence tomography (OCT).

Patients and Methods:

OCT was performed for 14 patients with unilateral strabismic amblyopia who had no neurologic disease. Nine male and 5 female patients, whose ages ranged from 5 to 18 years, were enrolled in the study. The RNFL thickness average analysis program was used to evaluate mean superior, inferior, temporal, and nasal thickness. The data for all clock quadrants (12 values averaged) were identified as the overall RNFL. The retinal thickness and volume analysis program was used to evaluate macular scans. Data were compared using the Mann–Whitney
U
test.

Results:

The mean age (± standard deviation) was 10.43 years (± 4.09 years). There were 6 right eyes and 8 left eyes with amblyopia; this group had a mean visual acuity (± standard error) of 0.3 (± 5.70). OCT parameters including the RNFL thickness in all quadrants, overall RNFL thickness, macular thickness, and macular volume showed no significant differences between the two groups (
P
> .05).

Conclusion:
Assessment of RNFL thickness, macular thickness, and macular volume with OCT revealed no difference between the two eyes of patients with unilateral strabismic amblyopia.

Spontaneous Regression of Retinoblastoma in a Taiwan Series
Authors: Kao Ling Yuh , Yang Meng Ling 
Published: April 2020

Purpose:
To document the high occurrence of complete spontaneous regression of retinoblastoma in a Taiwan series.

Patients and Methods:
Cases of retinoblastoma (133 eyes of 110 patients) at a single Taiwanese hospital from 1978 to 2002 were reviewed.

Results:
Complete spontaneous tumor regression and phthisis bulbi were noted in 7 eyes of 7 patients. The regression rate was 5.3%, which is higher than previous reports of 1% to 2%. Tumor regression was associated with a common course of acute painful inflammation and ended with a shrunken, nonfunctioning eye. No residual vision was noted in any patient.

Conclusion:
Delayed diagnosis and advanced stage of the disease in this series of Taiwanese patients probably led to the massive intratumoral necrosis and resulted in phthisic change of the globe.

Assessing Accuracy of Sampling Schemes to Estimate Western Snowy Plover Reproductive Success
Authors: Henkel Laird A. , Neuman Kriss K. , Stein R. William , Stenzel Lynne E. 
Published: April 2020

AbstractLike many wildlife species of management concern, the western snowy plover Charadrius nivosus nivosus is the subject of intensive population monitoring. However, intensive monitoring of reproductive success for this shorebird is time-consuming, financially costly, and potentially disruptive to the birds of interest. These constraints mean that intensive monitoring is not feasible throughout the range of the federally threatened Pacific Coast population. In this study, we used data collected from one intensively monitored subpopulation to assess how reductions in monitoring effort (number of chicks individually marked) would affect the accuracy of estimates of fledging success for western snowy plover chicks. We used monitoring data collected on chicks hatching at 1,845 nests from 2003 to 2012 as a theoretical subpopulation from which to draw random samples for this assessment. As expected, we found that accuracy (as measured by the inverse of percentage difference between sampled and actual fledge rates) increased with increasing percentage of the subpopulation monitored each year. We also found that the day of the week that chicks hatched and were banded had no effect on fledging success. Thus, reducing monitoring effort by banding chicks on specific days of the week is one suitable method for subpopulation sampling that has no embedded biases in the subsequent estimate of fledging success. The results of our analyses provide estimates of the accuracy of different sampling schemes, which should help managers of this threatened shorebird assess appropriate monitoring methods. We recommend use of our methods for others interested in assessing accuracy of sampling schemes for reproductive success of western snowy plover or other birds with similar life-history traits.

The Alchemy of Us
Authors: Ramirez Ainissa 
Published: April 2020

In the bestselling tradition of Stuff Matters and The Disappearing Spoon: a clever and engaging look at materials, the innovations they made possible, and how these technologies changed us.
One of the Best Summer Science Books of 2020 by Science Friday | Named one of Smithsonian Magazine's Ten Best Science Books of 2020 | Finalist for the Los Angeles Times Book Award in Science and Technology | Winner of the 2021 AAAS/Subaru SBF Prize in the Young Adult Science Book Category
In The Alchemy of Us, scientist and science writer Ainissa Ramirez examines eight inventions—clocks, steel rails, copper communication cables, photographic film, light bulbs, hard disks, scientific labware, and silicon chips—and reveals how they shaped the human experience. Ramirez tells the stories of the woman who sold time, the inventor who inspired Edison, and the hotheaded undertaker whose invention pointed the way to the computer. She describes, among other things, how our pursuit of precision in timepieces changed how we sleep; how the railroad helped commercialize Christmas; how the necessary brevity of the telegram influenced Hemingway's writing style; and how a young chemist exposed the use of Polaroid's cameras to create passbooks to track Black citizens in apartheid South Africa. These fascinating and inspiring stories offer new perspectives on our relationships with technologies.
Ramirez shows not only how materials were shaped by inventors but also how those materials shaped culture, chronicling each invention and its consequences—intended and unintended. Filling in the gaps left by other books about technology, Ramirez showcases little-known inventors—particularly people of color and women—who had a significant impact but whose accomplishments have been hidden by mythmaking, bias, and convention. Doing so, she shows us the power of telling inclusive stories about technology. She also shows that innovation is universal—whether it's splicing beats with two turntables and a microphone or splicing genes with two test tubes and CRISPR.
