Abstract
We report on the results of X-ray observations of 4XMM J111816.0–324910, a transient ultraluminous X-ray source located in the galaxy NGC 3621. This system is characterized by a transient nature and marked variability with a characteristic timescale of ≈3500 s, in contract with other ultraluminous X-ray sources, which in the vast majority show limited intra-observation variability. Such a behavior is very reminiscent of the so-called heartbeats sometimes observed in the Galactic black hole binary GRS 1915+105, where the variability timescale is ∼10–1000 s. We study the spectral and timing properties of this object and find that overall, once the differences in the variability timescales are taken into account, they match quite closely those of both GRS 1915+105 and of a number of objects showing heartbeats in their light curves, including a confirmed neutron star and a supermassive black hole powering an active galactic nucleus. We investigate the nature of the compact object in 4XMM J111816.0–324910 by searching for typical neutron star signatures and by attempting a mass estimate based on different methods and assumptions. Based on the current available data, we are not able to unambiguously determine the nature of the accreting compact object responsible for the observed phenomenology.

Abstract
3C 82 at a redshift of 2.87 is the most distant 3C (Third Cambridge Catalogue) quasar. Thus, it is a strong candidate to have the most-luminous radio lobes in the universe. 3C 82 belongs to the class of compact steep-spectrum radio sources. We use single-dish and interferometric radio observations in order to model the plasma state of these powerful radio lobes. It is estimated that the long-term time-averaged jet power required to fill these lobes with leptonic plasma is

, among the largest time-averaged jet powers from a quasar. Positing protonic lobes is not tenable as they would require two orders of magnitude more mass transport to the lobes than was accreted to the central black hole during their formation. The first high signal-to-noise optical spectroscopic observation obtained of this object indicates that there is a powerful high-ionization broad-line wind with a kinetic power of ∼1045 erg s−1 and a velocity of ∼0.01c. We also estimate from the broad lines in 2018 and the UV continuum in three epochs spread out over three decades that the accretion flow bolometric luminosity is L
bol ≈ 3.2–5.8 × 1046 erg s−1. The ratio of

is perhaps the largest of any known quasar. Extremely powerful jets tend to strongly suppress powerful winds of ionized baryonic matter. Consequently, 3C 82 provides a unique laboratory for studying the dynamical limits of the central engine of outflow initiation in quasars.
First Detection of the GI-type of Intrinsic Alignments of Galaxies Using the Self-calibration Method in a Photometric Galaxy Survey

Published: August 2020

Abstract
Weak gravitational lensing is one of the most promising cosmological probes to constrain dark matter, dark energy, and the nature of gravity at cosmic scales. Intrinsic alignments (IAs) of galaxies have been recognized as one of the most serious systematic effects facing gravitational lensing. Such alignments must be isolated and removed to obtain a pure lensing signal. Furthermore, the alignments are related to the processes of galaxy formation, so their extracted signal can help in understanding such formation processes and improving their theoretical modeling. We report in this Letter the first detection of the gravitational shear–intrinsic shape (GI) correlation and the intrinsic shape–galaxy density (Ig) correlation using the self-calibration method in a photometric redshift survey. These direct measurements are made from the KiDS-450 photometric galaxy survey with a significance of 3.65σ in the third bin for the Ig correlation, and 3.51σ for the GI cross-correlation between the third and fourth bins. The self-calibration method uses the information available from photometric surveys without needing to specify an IA model and will play an important role in validating IA models and IA mitigation in future surveys such as the Rubin Observatory Legacy Survey of Space and Time, Euclid, and WFIRST.
An Interstellar Synthesis of Glycerol Phosphates

Published: August 2020

Abstract
Glycerol phosphates define key molecules pertaining to the Origin of Life question and represent the essential stereo-dictating unit of phospholipids that may self-assemble in aqueous media into prebiotic cell membranes. However, the prebiotic formation pathways to glycerol phosphate have remained elusive to date. In this Letter, we expose a facile pathway toward the abiotic synthesis of glycerol phosphate isomers in phosphine (PH3) doped interstellar analog ices of methanol (CH3OH), carbon dioxide (CO2), or water (H2O) upon exposure to energetic electrons as a proxy of secondary electrons generated by the penetration of Galactic cosmic rays into interstellar ices at 10 K. The synthetic routes proposed here overcome obstacles of terrestrial-based scenarios that are inhibited by the low solubility of phosphates in water and the unfavorable nature of phosphorylation reactions in aqueous solution, thus revealing a potential pathway to prebiotic glycerol phosphates.
On the Relation between Diffuse Bands and Other Interstellar Features*
Authors: Krełowski J. , Galazutdinov G. A. , Siebenmorgen R. 
Published: August 2020

Abstract
We discuss possible relations between different constituents of interstellar clouds, such as gas atoms (Fe i), simple molecular species (CH, CN), and the carriers of the puzzling diffuse interstellar bands (DIBs 5780, 5797, 5850 Å) as well as dust grains. We exemplify that abundances of carriers of these spectral features, revealed by the Doppler components, may be astonishingly poorly related to each other. Spectra of interstellar clouds seem to be sensitive to the changes of the environmental parameters such as density, temperature, and irradiation from nearby stars. The diffuse bands’ carriers likely do not occupy the same volumes with CH, CN, or Fe i and/or are much less sensitive to the processes related to the formation/destruction of these species.

Authors: Johnston Sandra , Fox Amanda 
Published: August 2020

Background:
Education in the tertiary setting that is specifically focused on prevention and responding to workplace violence during clinical practice may increase nursing students' ability to respond to violence in the workplace. Kirkpatrick's model of evaluation categorizes outcomes into four levels. Educational impact provides valuable feedback to educators that may assist with development and improvement of teaching methods.

Method:
This review is based on the PRISMA guidelines for conducting a systematic review. Inclusion criteria included articles that (a) were written in the English language, (b) were peer reviewed, (c) described an educational program relating to workplace violence in an undergraduate nursing program, and (d) were published between 2000 and 2019.

Results:
Six studies met the criteria for inclusion in this review.

Conclusion:

Simulation emerged as a learning and teaching strategy that may be effective in teaching about workplace violence. Future studies should aim to evaluate the effects of education on behavior change and transfer to practice.

Teaching Health Assessment Symptomatology Using a Flipped Classroom Combined With Scenario Simulation
Authors: Wang Ximin , Dong Lu , Lyu Weibo , Geng Zhaohui 
Published: August 2020

Background:
Symptom assessment is difficult to understand and be retained by second-year bachelor's nursing students. A flipped classroom combined with scenario simulation (FCSS) is a new potential teaching model. This study compares the teaching effect and knowledge retention between the FCSS approach and the traditional flipped classroom (FC) approach.

Method:

Second-year bachelor's nursing students were selected as research participants. One group (
n
= 59) adopted an FCSS approach, whereas the other group (
n
= 68) adopted an FC approach. We evaluated student mastery and retention of knowledge through two tests: one before the next class, the other after 2 months.

Results:

Regarding knowledge mastery, the FC group had a higher score than the FCSS group both in total score (66.29 ± 15.27 versus 59.42 ± 10.76) and group learning score (46.06 ± 13.25 versus 38.47 ± 8.22) in the first test (
p
< .05). The retention of knowledge in the FCSS group was better than that in the FC group (
p
< .001), represented by the variable of test score difference before and after 2 months.

Conclusion:

When teaching symptomatology, FCSS is helpful to enhance self-learning and improve student long-term memory.

TCR Signal Strength and Antigen Affinity Regulate CD8+ Memory T Cells
Authors: Solouki Sabrina , Huang Weishan , Elmore Jessica , Limper Candice , Huang Fei , August Avery 
Published: August 2020

Abstract
CD8+ T cells play a critical role in adaptive immunity, differentiating into CD8+ memory T cells that form the basis of protective cellular immunity. Vaccine efficacy is attributed to long-term protective immunity, and understanding the parameters that regulate development of CD8+ T cells is critical to the design of T cell–mediated vaccines. We show in this study using mouse models that two distinct parameters, TCR signal strength (regulated by the tyrosine kinase ITK) and Ag affinity, play important but separate roles in modulating the development of memory CD8+ T cells. Unexpectedly, our data reveal that reducing TCR signal strength along with reducing Ag affinity for the TCR leads to enhanced and accelerated development of CD8+ memory T cells. Additionally, TCR signal strength is able to regulate CD8+ T cell effector cytokine R production independent of TCR Ag affinity. Analysis of RNA-sequencing data reveals that genes for inflammatory cytokines/cytokine receptors are significantly altered upon changes in Ag affinity and TCR signal strength. Furthermore, our findings show that the inflammatory milieu is critical in regulating this TCR signal strength–mediated increase in memory development, as both CpG oligonucleotide treatment or cotransfer of wild-type and Itk−/− T cells eliminates the observed increase in memory cell formation. These findings suggest that TCR signal strength and Ag affinity independently contribute to CD8+ memory T cell development, which is modulated by inflammation, and suggest that manipulating TCR signal strength along with Ag affinity, may be used to tune the development of CD8+ memory T cells during vaccine development.
Today’s improvement in asthma treatment: role of MART and Easyhaler
Authors: Di Marco Fabiano 
Published: August 2020

Asthma affects more than 330 million people worldwide, but many analyses have shown that there are still a lot of unmet needs for both patients and physicians in the treatment of asthma: poor adherence to treatment is one of the main causes of sub-optimal clinical results. Maintenance and Reliever Therapy (MART) with the combination of formoterol and inhaled corticosteroids (ICS) has an established scientific rationale and demonstrated to reduce asthma exacerbations. The aim of this review is to highlight how in asthmatic patients MART can be able to express its maximum therapeutic potential when administered through an ‘ideal inhaler’. Since the treatment may be necessary several times a day, the use of a single combination inhaler simplifies the management, potentially improving adherence; moreover, easiness of use and comfort in administration of asthma treatment devices are not secondary aspects. Asthmatic patients are often young, with a normal relational and working life and they could request for a comfortable and not too noticeable device. Finally to the “ideal inhaler” is requested to guarantee accuracy, dose consistency, and resistance to stress conditions. Easyhaler® more closely demonstrates many expected characteristics: effective, consistent performance regardless of inspiration rate, stability, versatility, with several patient acceptability advantages. Asthma control is enhanced by a strong adherence obtained through the combination in a single inhaler of both maintenance and reliever therapy and the availability of a device as close as possible to the characteristics of the ideal inhaler.
The cubic Schrödinger regime of the Landau–Lifshitz equation with a strong easy-axis anisotropy
Authors: de Laire André , Gravejat Philippe 
Published: August 2020

We pursue our work on the asymptotic regimes of the Landau–Lifshitz equation. We put the focus on the cubic Schrödinger equation, which is known to describe the dynamics of uniaxial ferromagnets in a regime of strong easy-axis anisotropy. In any dimension, we rigorously prove this claim for solutions with sufficient regularity. In this regime, we additionally classify the one-dimensional solitons of the Landau–Lifshitz equation and quantify their convergence towards the solitons of the one-dimensional cubic Schrödinger equation.
Our proof is based on a nonlinear rewriting of the Landau–Lifshitz equation for uniaxial ferromagnets as a nonlinear Schrödinger equation. This latter equation turns out to be consistent with the cubic Schrödinger equation in a regime of strong easy-axis anisotropy. We rely on this consistency to perform suitable energy estimates and then control the difference between the solutions of the two equations.
