Abstract
We report the discovery of four transiting giant planets around K dwarfs. The planets HATS-47b, HATS-48Ab, HATS-49b, and HATS-72b have masses of

,

,

, and

, respectively, and radii of

,

,

, and

, respectively. The planets orbit close to their host stars with orbital periods of

days,

days,

days, and

days, respectively. The hosts are main-sequence K dwarfs with masses of

,

,

, and

, and with V-band magnitudes of

,

,

and

. The super-Neptune HATS-72b (a.k.a. WASP-191b and TOI 294.01) was independently identified as a transiting planet candidate by the HATSouth, WASP, and TESS surveys, and we present a combined analysis of all of the data gathered by each of these projects (and their follow-up programs). An exceptionally precise mass is measured for HATS-72b thanks to high-precision radial velocity (RV) measurements obtained with VLT/ESPRESSO, FEROS, HARPS, and Magellan/PFS. We also incorporate TESS observations of the warm Saturn–hosting systems HATS-47 (a.k.a. TOI 1073.01), HATS-48A, and HATS-49. HATS-47 was independently identified as a candidate by the TESS team, while the other two systems were not previously identified from the TESS data. The RV orbital variations are measured for these systems using Magellan/PFS. HATS-48A has a resolved

neighbor in Gaia DR2, which is a common-proper-motion binary star companion to HATS-48A with a mass of 0.22

and a current projected physical separation of ∼1400 au.
Thunder and Lightning: Using Neutron-star Mergers as Simultaneous Standard Candles and Sirens to Measure Cosmological Parameters
Authors: Doctor Zoheyr 
Published: March 2020

Abstract
With the detection of gravitational wave (GW) GW170817 and its associated electromagnetic (EM) counterparts from a binary neutron star (NS) merger, the “standard siren” method for Hubble-constant measurements is expected to play a role in the Hubble-constant tension in the next few years. One intriguing proposal put forward in multiple studies is to use an NS merger’s optical counterpart, known as a kilonova, as a standard candle, because its absolute magnitude can in principle be calculated from simulations. In this work, I detail the statistical framework for performing joint standard-candle and standard-siren measurements using GWs, EM follow-up data, and simulations of EM counterparts. I then perform an example analysis using GW170817 and its optical counterpart AT2017gfo to illustrate the method and the method’s limitations. Crucially, the inferences using this method are only as robust as the EM counterpart models, so significant theoretical advances are needed before this method can be employed for precision cosmology.
Periodic Fast Radio Bursts with Neutron Star Free Precession
Authors: Zanazzi J. J. , Lai Dong 
Published: March 2020

Abstract
The CHIME/FRB collaboration recently reported the detection of a 16 day periodicity in the arrival times of radio bursts from FRB 180916.J0158+65. We study the possibility that the observed periodicity arises from free precession of a magnetized neutron star, and put constraints on different components of the star’s magnetic fields. Using a simple geometric model, where radio bursts are emitted from a rotating neutron star magnetosphere, we show that the emission pattern as a function of time can match that observed from FRB 180916.J0158+65.
Types of Intensive Care Units With the Healthiest, Most Productive Work Environments
Authors: Schmalenberg Claudia , Kramer Marlene 
Published: March 2020

Background The quality of nurses’ work environments in hospitals is of great concern. The American Association of Critical-Care Nurses has specified 6 standards essential to a healthy (ie, satisfying and productive) work environment. These standards are sufficiently aligned to the Essentials of Magnetism processes to make this tool suitable for measuring healthy work environments.Objectives To identify differences in staff nurses’ perceptions of the work environment by type of intensive care unit.Methods A cross-sectional descriptive design with strategic sampling was used in this secondary analysis of data from 698 staff nurses working in 34 intensive care units in 8 magnet hospitals. Intensive care units were grouped into 4 types: medical, including coronary care; surgical, including trauma and cardiovascular; neonatal and pediatric; and medical-surgical. All nurses completed the Essentials of Magnetism instrument. Analysis of variance was used to identify initial differences; multivariate analysis of variance was used to control for covariates.Results The intensive care nurses and units scored above the National Magnet Hospital Profile mean on process variables and on the Essentials of Magnetism outcome variables. Neonatal and pediatric units scored significantly higher than did the other types of intensive care units sampled.Conclusions Intensive care unit structures supported care processes and relationships that resulted in job satisfaction among nurses and high-quality care for patients in this strategic sample. Systematic study of the structures and processes present in units reporting a healthy work environment can be used to assist other clinical units in improving work environments.

Published: March 2020

Background Signs and symptoms of acute coronary syndromes differ between men and women, but whether men and women respond differently to these indications is not well understood. Such responses influence health outcomes because success of treatment depends on how quickly healthcare is sought.
Objective To explore differences between Lebanese men and women in cognitive, emotional, and behavioral responses to signs and symptoms of acute coronary syndromes.
Methods A convenience sample of 149 men and 63 women with unstable angina or acute myocardial infarction were interviewed within 72 hours of admission to coronary care in a tertiary center by using the Response to Symptoms Questionnaire. Demographic and clinical data were obtained from medical records.
Results Women were older, less educated, and more often widowed than men. More women had hypertension but more men were current smokers. Women had shoulder pain, dyspnea, nausea and vomiting, and palpitations more often than men did. Women’s signs and symptoms were rated more severe by the women than men’s were by the men. Women were less likely to know signs and symptoms of myocardial infarction than were men and delayed coming to the hospital longer than men did. Delay correlated with the characteristics of the signs and symptoms and not realizing their importance in men and with dyspnea and taking the “wait and see” approach in women.
Conclusion Factors related to promptness in seeking care for acute coronary syndromes differ between Lebanese men and women.

Published: March 2020

Background Unplanned extubations can result in serious complications.Objectives To determine characteristics of patients and nurses and risk factors that affect extubations.Methods A retrospective exploratory design was used. Ram-say Sedation Scale scores, need for reintubation, time between intubation and extubation, use of sedation and analgesia in the preceding 48 hours, and use of restraints were collected on 31 patients in a surgical intensive care unit who had unplanned extubations. For nurses, data collected included years’ experience in nursing and as an intensive care nurse, professional credentials, and location at the time of extubation.Results All unplanned extubations were self-extubations; 15 required reintubation. Most patients had low levels of sedation in the hour preceding the extubation (mean Ramsay score, 2.42; SD, 1.06). Patients who needed reintubation had higher mean Ramsay scores (2.85; SD, 1.14) than patients who did not (2.00; SD, 0.86; P = .04). Ramsay scores correlated with need for reintubation (r=0.423; P=.03). Of the 31 patients, 27 (87%) were restrained at the time of extubation (χ2 = 17.06; df=1; P&lt;.001). Among the nurses, 32.3% had less than 5 years’ experience in nursing, and 51.6% had less than 5 years’ experience in intensive care; 89% of extubations occurred when the nurse was away from the bedside. Sedative and analgesic doses in the 24 hours before extubation did not differ significantly from those in the 2 hours before extubation.Conclusions Levels of sedation and use of restraints are associated with unplanned extubations and need for reintubation.

Published: March 2020

Background The helpfulness of bedside assessment of gastric residual volume in the prediction of aspiration has been questioned, as has the volume that signals increased risk of aspiration.
Objective To describe the association between gastric residual volumes and aspiration of gastric contents.
Methods In a prospective study of 206 critically ill patients receiving gastric tube feedings for 3 consecutive days, gastric residual volumes were measured with 60-mL syringes every 4 hours. Measured volumes were categorized into 3 overlapping groups: at least 150 mL, at least 200 mL, and at least 250 mL. Patients were categorized as frequent aspirators if 40% or more of their tracheal secretions were positive for pepsin and as infrequent aspirators if less than 40% of their secretions were positive for pepsin. Gastric residual volumes were compared between the 2 aspiration groups.
Results Approximately 39% of the 206 patients had 1 or more gastric residual volumes of at least 150 mL, 27% had 1 or more volumes of at least 200 mL, and 17% had 1 or more volumes of at least 250 mL. Large-bore tubes identified most of the high volumes. Eighty-nine patients were frequent aspirators. Volumes less than 150 mL were common in both aspiration groups. However, the frequent aspirators had a significantly greater frequency of 2 or more volumes of at least 200 mL and 1 or more volumes of at least 250 mL.
Conclusions No consistent relationship was found between aspiration and gastric residual volumes. Although aspiration occurs without high gastric residual volumes, it occurs significantly more often when volumes are high.

Abstract. Biomass burning and primary biological aerosol particles
account for an important part of urban aerosols. Floods of studies have been
conducted on the chemical compositions of fine aerosols (PM2.5) in
megacities where the haze pollution is one of the severe environmental
issues in China. However, little is known about their size distributions in
atmospheric aerosols in the urban boundary layer. Here, size-segregated
aerosol samples were collected in Beijing during haze and clear days from
April 2017 to January 2018. Three anhydrosugars, six primary saccharides and
four sugar alcohols in these samples were identified and quantified by gas
chromatography/mass spectrometry (GC/MS). Higher concentrations of a biomass
burning tracer, levoglucosan, were detected in autumn and winter than in other
seasons. Sucrose, glucose, fructose, mannitol and arabitol were more
abundant in the bloom and glowing seasons. A particularly high level of
trehalose was found in spring, which was largely associated with the Asian
dust outflows. Anhydrosugars, xylose, maltose, inositol and erythritol
are mainly present in the fine mode (<2.1 µm), while the others
showed the coarse-mode preference. The concentrations of measured tracers of
biomass burning particles and primary biological particles in the haze
events were higher than those in the non-hazy days, with enrichment factors
of 2–10. Geometric mean diameters (GMDs) of molecular markers of biomass
burning and primary biological aerosols showed that there was no significant
difference in the coarse mode (>2.1 µm) between the haze
and non-haze samples, while a size shift towards large particles and large
GMDs in the fine fraction (<2.1 µm) was detected during the
hazy days, which highlights that the stable meteorological conditions with
high relative humidity in urban Beijing may favor the condensation of
organics onto coarse particles.The contributions of reconstructed primary
organic carbon (POC) by tracer-based methods from plant debris, fungal
spores and biomass burning to aerosol OC in the total-mode particles were
in the ranges of 0.09 %–0.30 % (on average 0.21 %), 0.13 %–1.0 %
(0.38 %) and 1.2 %–7.5 % (4.5 %), respectively. This study demonstrates
that the contribution of biomass burning was significant in Beijing
throughout the whole year with the predominance in the fine mode, while the
contributions of plant debris and fungal spores dominated in spring and
summer in the coarse mode, especially in sizes >5.8 µm. Our observations demonstrate that the sources, abundance and chemical
composition of urban aerosol particles are strongly size dependent in
Beijing, which is important to better understand the environmental and
health effects of urban aerosols and should be considered in air quality and climate models.
P-model v1.0: an optimality-based light use efficiency model for simulating ecosystem gross primary production

Published: March 2020

Abstract. Terrestrial photosynthesis is the basis for vegetation growth and drives the land carbon cycle. Accurately simulating gross primary production (GPP, ecosystem-level apparent photosynthesis) is key for satellite monitoring and Earth system model predictions under climate change. While robust models exist for describing leaf-level photosynthesis, predictions diverge due to uncertain photosynthetic traits and parameters which vary on multiple spatial and temporal scales. Here, we describe and evaluate a GPP (photosynthesis per unit ground area) model, the P-model, that combines the Farquhar–von Caemmerer–Berry model for C3 photosynthesis with an optimality principle for the carbon assimilation–transpiration trade-off, and predicts a multi-day average light use efficiency (LUE) for any climate and C3 vegetation type. The model builds on the theory developed in Prentice et al. (2014) and Wang et al. (2017a) and is extended to include low temperature effects on the intrinsic quantum yield and an empirical soil moisture stress factor. The model is forced with site-level data of the fraction of absorbed photosynthetically active radiation (fAPAR) and meteorological data and is evaluated against GPP estimates from a globally distributed network of ecosystem flux measurements. Although the P-model requires relatively few inputs, the R2 for predicted versus observed GPP based on the full model setup is 0.75 (8 d mean, 126 sites) – similar to comparable satellite-data-driven GPP models but without predefined vegetation-type-specific parameters. The R2 is reduced to 0.70 when not accounting for the reduction in quantum yield at low temperatures and effects of low soil moisture on LUE. The R2 for the P-model-predicted LUE is 0.32 (means by site) and 0.48 (means by vegetation type). Applying this model for global-scale simulations yields a total global GPP of 106–122 Pg C yr−1 (mean of 2001–2011), depending on the fAPAR forcing data. The P-model provides a simple but powerful method for predicting – rather than prescribing – light use efficiency and simulating terrestrial photosynthesis across a wide range of conditions. The model is available as an R package (rpmodel).

Published: March 2020

El propósito de este estudio fue caracterizar los rendimientos en habla y en canto de dos pacientes con disartria atáxica a causa de un accidente cerebro vascular (ACV) cerebeloso con el fin de describir sus resultados en relación a las características clínicas y sociodemográficas que poseen.
Corresponde a un estudio de caso de tipo cuantitativo, con un diseño no experimental-transversal y un alcance descriptivo. Ambos sufrieron un ACV cerebeloso pero difieren en las características de la disartria, la técnica vocal, la edad, la frecuencia terapéutica, entre otras. Los instrumentos que se utilizaron para la medición de las variables fueron: el Protocolo de Evaluación de Habla (González y Toledo, 2002), el Protocolo de Habla versus Canto para pacientes disártricos, el cuestionario Voice Handicap Index (VHI) de Núñez-Batalla et al. (2007) y la escala RASATI (Pinho y Pontes, 2002).
Los resultados indicaron que quien padece de una disartria atáxica leve presenta mejores resultados en habla y en canto en comparación con aquel que padece de una disartria moderada. Esto se explica por las diversas diferencias que ambos poseen en cuanto a la severidad del cuadro, a las características neurológicas, a la frecuencia de terapia, a la edad y a la técnica vocal previa al evento vascular.
Ambos sufren alteraciones en los procesos motores básicos de respiración, fonación y prosodia.
The Israel Question after Trump—and Before
Authors: Rossinow Doug 
Published: March 2020

ABSTRACTThe new Jew-hatred of the Trump era, and reactions to it, seem hopelessly snarled with feelings for or against Israel. The tight association of Jewishness with Zionism is not an automatic or “natural” consequence of ineluctable historical facts, but rather a product of historical acts by many Americans, prominently including American Jews. Throughout the decades following the establishment of the State of Israel in 1948, American Jewish supporters of Israel worked consciously to establish the very conflation between Zionism and Jewish identity in the United States that now sometimes appears toxic. After the 1967 war, American Jewish forces across most of the ideological spectrum supported Israel’s retention of the Occupied Territories, particularly East Jerusalem, and the Democratic and Republican Parties ultimately embraced that stance by calling for the relocation of the US embassy in Israel to Jerusalem. Therefore, the Trump administration’s decision to move the embassy to Jerusalem, far from a sharp break with mainstream American and Jewish politics, followed a long political process that made it seem, to many Americans, that supporting Israel without stint equaled pro-Jewishness.
“Oppression by Orgasm”: Pornography and Antisemitism in Far-Right Discourses in the United States Since the 1970s
Authors: Kerl Kristoff 
Published: March 2020

ABSTRACT
This article scrutinizes the far-right phantasm of a Jew-led “porn conspiracy” from the 1970s until today in the United States and, consequently, points to the significance of sexuality for the study of antisemitism. The idea that Jews threatened the patriarchal sexual order by spreading “obscene” cultural products and, thus, constituted a threat for white supremacy can be traced back, at least, into the last decades of the nineteenth century and was, of course, not limited to the United States. With the rise of so-called porno chic during the early 1970s, the fantasy of a “porn conspiracy,” embedded into the broader antisemitic notion of a Jew-led and anti-white regime of “minority racism,” increasingly gained ground in the far right in the United States. Nowadays, against the backdrop of intensifying masculinism in general and a growing masculinist anti-porn movement in particular, far-right antisemites try to make use of antipornography to spread antisemitic conspiracy narratives beyond the far right into the mainstream.
The many functions of Cuzco Quechua =<i>pas</i>: implications for the semantic map of additivity
Authors: Faller Martina 
Published: March 2020

The additive enclitic =pas of Cuzco Quechua is multifunctional: besides marking additivity it also participates in the marking of concessivity, epistemic possibility and the formation of non-specific indefinite pronouns. This paper provides a description of these functions and proposes that they all involve a presupposition of existential quantification over alternatives. Their differences result from the type of alternatives quantified over, namely focus, epistemic or wh-alternatives. The particular clustering of functions found with =pas has implications for the semantic map of additivity proposed by Forker (2016), and presents a counterexample to three implicational universals it encapsulates. Modifications to the map are proposed to accommodate =pas, including connecting it with the semantic map of modality, and recognizing scalar additivity as a subtype of additivity.
