Postlabial raising and paradigmatic leveling in A’ingae: A diachronic study from the field
Authors: Dąbkowski Maksymilian 
Published: April 2023

This paper discusses and analyzes the variation between ai and ɨi in A’ingae(or Cofán, an Amazonian isolate, ISO 639-3: con) by comparing the data reported in Borman’s (1976) dictionary with contemporary productions. In Borman (1976), ai does not generally appear after labial consonants; the distribution of ɨi is not restricted. In some modern productions, postlabial ai is allowed when the diphthong crosses a morpheme boundary (a + i). I propose that Borman’s (1976) distribution of ai and ɨi is a consequence of a diachronic change of ai to ɨi after labial consonants (* ai > ɨi /B _). The contemporary distribution reflects paradigm leveling and contact-induced replacement: Borman’s (1976) ɨi corresponds to contemporary ai if a is present in another related form. In novel productively-formed words, the availability of postlabial raising is speaker-specific. The proposed sound change of postlabial raising (*ai > ɨi /B _) is unusual and lacks obvious phonetic motivation. I speculate that postlabial raising reflects postlabial rounding (*ai > * ui /B _) opacified by subsequent unconditioned unrounding and centralizing of the back round vowel (* u > ɨ).
Ͻkere is doing something different in adnominal possession
Authors: Oppong Okrah 
Published: April 2023

Cross-linguistically, some languages make a morphosyntactic distinction between alienable and inalienable adnominal possession, where alienable possession is more morphologically marked, and inalienable possession shows a tighter structural bond between the possessor and possessee. In this paper, I show that Ɔkere violates these cross-linguistic generalizations differently. I also show that two types of mó occur in the language, one is a possessive marker, and the other is an independent pronoun. Again, I show that the nature of the possessive marker and the independent pronoun leads to a pro-drop in inalienable possession. The data and analysis in this paper favor proposing an overt possessive marker and a covert possessive marker. This paper adds to the literature on the exceptions to the cross-linguistic generalizations on adnominal possession by showing that the exceptions to the cross-linguistic generalizations may manifest differently in some languages.
Dependency formation interacts with case: Evidence from Korean double nominative constructions
Authors: Cho Juyeon , Tollan Rebecca 
Published: April 2023

The subject-object asymmetry in relative clauses, where structures containing subject dependencies are typically easier to process than those with object dependencies, has been previously attributed to both grammatical function (subject > object) as well as morphological case (e.g., nom > acc). We investigate processing of Double Nominative Constructions (“DNCs”) in Korean, where the object exceptionally has nominative case like the subject (i.e., nom-nom). This enables isolation of grammatical function and case as possible factors driving the so-called “subject advantage.” We find that dependency formation is more costly in DNCs as compared with nom-acc structures, especially for object relative clauses. We tie this effect to distinctness in morphological case of the subject and object, suggesting that the less morphosyntactically distinct the subject and object are, the more difficult it is to process DNCs in dependencies.
Generic interpretations of possessive recursion in English-speaking children
Authors: Poisson Tyler , De Villiers Jill , Kyuchukov Hirsto , Weinand Bea , Young Lillian , Morales Sofia , Aniceto Laisha 
Published: April 2023

Two-part s-possessives such as the dad’s kid’s bike admit at least two distinct interpretations: the dad has a kid who has a bike, or the dad has a bike that is made for kids. We propose that the former interpretation derives from recursively embedding DP-possessives, and the latter from representing kid’s bike as a generic NP-possessive. Accordingly, in the right context, two-part s-possessives are fully ambiguous for adults between ‘recursive’ and ‘generic’ readings. These readings can be disambiguated syntactically. Consider the difference in meaning when we insert a relative clause and extract the constituent kid’s bike — the kid’s bike that is the dad’s — versus when we extract the head noun bike — the bike that is the dad’s kid’s. Our story-based experiment demonstrates that 4-7-year-olds (N=79) and adults (N=68) strongly favor (~80%) the generic interpretation of phrases like the kid’s bike that is the dad’s, as the A-over-A constraint blocks the extraction of a DP-possessive out of a recursive DP. Similarly, adults show a strong preference (~80%) for recursive interpretations of phrases like the bike that is the dad’s kid’s, as the A-over-A constraint blocks the extraction of the head noun bike out of the generic NP-possessive kid’s bike. However, 4-5-year-olds admit generic readings of these recursive phrases 54% of the time; it is not until 6 or 7 years that children show an adult-like preference for the recursive interpretation (~80%). These data support two complementary claims. First, that recursive possessives are acquired late on account of their syntax, and second that children, like adults, represent generic possessives under a different syntactic node than regular possessives.
Modeling Mandarin rhotacization with Recursive Schemes
Authors: Zhu Ziling 
Published: April 2023

This paper pursues a novel analysis of Mandarin rhotacization using Sonority Scale and characterizes this phonological process computationally with BOOLEAN MONADIC RECURSIVE SCHEMES (BMRSs, Chandlee & Jardine 2021). Mandarin rhotacization shows an asymmetry between high front vowels (i.e. [i, y] and high back vowels [u] vowels. Diverging from previous phonetics-based accounts to explain this asymmetry (Chao 1968; Duanmu 2007; a. o.), I propose that adjacent segments compete in terms of sonority in order to surface and present a refined, detailed sonority ranking in Mandarin. Finally, the if...then...else syntax in BMRSs elegantly formalizes the sonority competition between segments.

Abstract
We apply the color–magnitude intercept calibration method (CMAGIC) to the Nearby Supernova Factory SNe Ia spectrophotometric data set. The currently existing CMAGIC parameters are the slope and intercept of a straight line fit to the linear region in the color–magnitude diagram, which occurs over a span of approximately 30 days after maximum brightness. We define a new parameter, ω

XY
, the size of the “bump” feature near maximum brightness for arbitrary filters X and Y. We find a significant correlation between the slope of the linear region, β

XY
, in the CMAGIC diagram and ω

XY
. These results may be used to our advantage, as they are less affected by extinction than parameters defined as a function of time. Additionally, ω

XY
is computed independently of templates. We find that current empirical templates are successful at reproducing the features described in this work, particularly SALT3, which correctly exhibits the negative correlation between slope and “bump” size seen in our data. In 1D simulations, we show that the correlation between the size of the “bump” feature and β

XY
can be understood as a result of chemical mixing due to large-scale Rayleigh–Taylor instabilities.

Abstract
Helium variations are common features of globular clusters (GCs) with multiple stellar populations. All the formation scenarios predict that secondary population stars are enhanced in helium, but the exact helium content depends on the polluters. Therefore, searching for helium variations in a star cluster is a straightforward method to understand whether it hosts multiple populations or not and to constrain the formation scenario. Although this topic has been well explored for Galactic GCs, GCs beyond the Milky Way are challenging to study because of their large distances. This work studies the helium distribution of GK-type main-sequence (MS) dwarfs in an old (∼12.5 Gyr) GC in the Large Magellanic Cloud, NGC 2210, using the deep photometry observed by the Hubble Space Telescope. We compare the observed morphology of the MS with that of synthetic populations with different helium distributions. We confirm that NGC 2210 dwarfs have a helium spread, with an internal dispersion of δ
Y ∼ 0.06–0.07. The fraction of helium-enriched stars depends on the δ
Y distribution. A continuous δ
Y distribution would indicate that more than half of MS stars are helium enriched (∼55%). If the δ
Y distribution is discrete (bimodal), a fraction of ∼30% enriched stars is able to explain the observed morphology of the MS. We also find that the He-enriched population stars are more centrally concentrated than He-normal stars.
Joint Modelling of Dust Scattering and Thermal Emission: The Spider Complex

Published: April 2023

Abstract
Observations across the electromagnetic spectrum of radiative processes involving interstellar dust—emission, absorption, and scattering—are used to constrain the parameters of dust models and more directly to aid in foreground removal of dust for extragalactic and cosmological observations. Dust models can benefit from more independent constraints from complementary observations. Here, we quantify the relationship between scattered light and thermal emission from dust in a diffuse (cirrus) intermediate-latitude cloud, Spider, using data from the Dragonfly Telephoto Array and the Herschel Space Observatory. A challenge for optical observations of faint diffuse cirrus is accurate removal of a contaminating, spatially varying sky. We present a technique to analyze two images of the same cirrus field concurrently, correlating pixel values to capture the relationship and simultaneously fitting the sky-related signal as a complex noncorrelating additive component. For the Spider, we measure a color g − r = 0.644 ± 0.024 and ratios of visible-wavelength to 250 μm intensity of γ

g,250 = (0.855 ± 0.025) × 10−3 and γ

r,250 = (1.55 ± 0.08) × 10−3 for the g and r-bands, respectively. We show how to use any dust model that matches the thermal dust emission to predict an upper limit to the amount of scattered light. The actual brightness of the cirrus will be fainter than this limit because of anisotropic scattering by the dust combined with anisotropy of the incident interstellar radiation field (ISRF). Using models of dust and the ISRF in the literature, we illustrate that the predicted brightness is indeed lower, though not as faint as the observations indicate.

Abstract
We present integral field, far-infrared (FIR) spectroscopy of Mrk 54, a local Lyman continuum emitter, obtained with FIFI-LS on the Stratospheric Observatory for Infrared Astronomy. This is only the second time, after Haro 11, that [C ii] 158 μm and [O iii] 88 μm spectroscopy of the known LCEs have been obtained. We find that Mrk 54 has a strong [C ii] emission that accounts for ∼1% of the total FIR luminosity, whereas it has only moderate [O iii] emission, resulting in the low [O iii]/[C ii] luminosity ratio of 0.22 ± 0.06. In order to investigate whether [O iii]/[C ii] is a useful tracer of f
esc (LyC escape fraction), we examine the correlations of [O iii]/[C ii] and (i) the optical line ratio of O32 ≡ [O iii] 5007 Å/[O ii] 3727 Å, (ii) specific star formation rate, (iii) [O iii] 88 μm/[O i] 63 μm ratio, (iv) gas-phase metallicity, and (v) dust temperature based on a combined sample of Mrk 54 and the literature data from the Herschel Dwarf Galaxy Survey and the LITTLE THINGS Survey. We find that galaxies with high [O iii]/[C ii] luminosity ratios could be the result of high ionization (traced by O32), bursty star formation, high ionized-to-neutral gas volume filling factors (traced by [O iii] 88 μm/[O i] 63 μm), and low gas-phase metallicities, which is in agreement with theoretical predictions. We present an empirical relation between the [O iii]/[C ii] ratio and f
esc based on the combination of the [O iii]/[C ii] and O32 correlation, and the known relation between O32 and f
esc. The relation implies that high-redshift galaxies with high [O iii]/[C ii] ratios revealed by the Atacama Large Millimeter/submillimeter Array may have f
esc ≳ 0.1, significantly contributing to the cosmic reionization.
In the Trenches of the Solar–Stellar Connection. VII. Wilson–Bappu 2022
Authors: Ayres Thomas 
Published: April 2023

Abstract
The Wilson–Bappu effect (WBE) is a remarkable correlation between the width of the chromospheric emission core of the Ca ii 3934 Å K line and stellar absolute visual magnitude over an astonishing range, from diminutive red dwarfs to bloated yellow supergiants. The WBE signifies a deep connection between the nonclassical, mechanically heated chromosphere and fundamental stellar properties. The present study considers the parallel WBE in the analogous Mg ii k line at 2796 Å, utilizing near-ultraviolet spectra from Hubble Space Telescope (HST), and stellar parameters mainly derived from Gaia. The final sample is 300 stars (301 including the Sun). The high cosmic abundance of magnesium allowed Mg ii k emissions to be recovered in the warmer F-types, at the edge of convection and chromospheric activity, and in low-activity Sunlike dwarfs—situations in which Ca ii K might be too weak to measure. Nevertheless, the derived slope of the Mg ii WBE was similar to previous reports based on the K line; as well as other Mg ii efforts with smaller samples of pre-HST spectra. Further, a decomposition of the Mg ii WBE in temperature, gravity, activity, and metallicity yielded similar results to previous Ca ii work, but with the greater clarity afforded by the large, diverse HST sample. Parametric dependences of the k-line WBE match, tolerably well, predictions based on the “ionization-valve” theory of chromospheric structure. In the end, the WBE is not merely an astrophysical curiosity, but rather informs the question of how chromospheres—arguably the central bastion of nonclassical heating—have come to be.
L’oiseau mazouté : usages et construction d’un symbole (1934-1991)
Authors: Dupuy Michel 
Published: April 2023

L’oiseau mazouté fait partie des figures classiques de la marée noire. Affiché au moment de la catastrophe, il finit cependant par être effacé. Son émergence a été lente. Constaté dans les années 1920, victime de pollution chronique, il ne s’impose qu’avec le naufrage de l’Amoco Cadiz en 1978 et après l’épisode du Torrey Canyon en 1967. L’image et l’expression d’« oiseau mazouté » ont donc fini par s’imposer, tout en étant porteur d’un discours qui diffère selon les périodes. Ainsi il devient tour à tour la victime du progrès, d’une société de consommation, d’une manipulation, etc.

Published: April 2023

Objective:
To explore the cardioprotective effect of hesperidin against arsenic trioxide-induced cardiac toxicity in rats.

Methods:
Cardiac toxicity was induced by oral administration of 4 mg/kg arsenic trioxide for 30 days. Hematological, biochemical, electrocardiography, echocardiography, and histopathological examinations were performed.

Results:
Hesperidin decreased the neutrophil-to-lymphocyte ratio, calcium, creatine kinase-myoglobin binding, lactate dehydrogenase, IL-6, and lipid peroxidation, as well as increased sodium and potassium concentration and superoxide dismutase and catalase activity in arsenic trioxide-intoxicated rats. Moreover, it reduced peak systolic velocity and end-diastolic velocity while increasing heart rate. Arsenic trioxide-induced histopathological damage to cardiac tissue was prominently alleviated by hesperidin treatment.

Conclusions:
Hesperidin attenuates arsenic trioxide-induced cardiac toxicity in rats. Therefore, it can be further explored as a cardioprotective agent.
Sclerosing Perivascular Epithelioid Cell Tumor of the Uterus
Authors: Kundu Reetu , Saha Pradip Kumar , Dey Pranab 
Published: April 2023

ABSTRACT
Perivascular epithelioid cell tumor (PEComa) is a rare mesenchymal uterine tumor and the histological variant, sclerosing PEComa is exceedingly rare. Sclerosing PEComas preferentially occur in the retroperitoneum and occurrence in the uterine corpus is seldom seen. These tumors pose a diagnostic challenge and need distinction from morphological mimickers such as epithelioid smooth muscle tumors, endometrial stromal sarcoma, and metastatic carcinoma. Accurate diagnosis can be established coupling histomorphology with immunostaining. The distinction from other entities is of prime importance considering the therapeutic and prognostic implications. Herein, we describe a case of uterine sclerosing variant of PEComa with diagnostic difficulties and key to diagnose this entity.
Physical Activity Levels, Motivators and Barriers to Exercise among Men and Women Aged 30 to 50 Years in Rourkela, India
Authors: Aneesh Mitravinda , Mahanta Nirupama 
Published: April 2023

ABSTRACT

Background:
Literature suggests that middle age is a period with increasing sedentary behavior and health risks.

Objective:
We conducted the present study to assess physical activity levels of the adults aged 30–50 years and understand the motivators and barriers to regular physical activity.

Materials and Methods:
A cross-sectional study was conducted among 100 adults aged 30–50 years residing in Rourkela, Odisha. The physical activity levels of the adults were assessed using Bouchard’s Physical Activity Record. Height, weight, and waist circumference of the participants were measured using standard procedures. A self-administered questionnaire was prepared to identify the motivators and barriers to physical activity/exercise behavior.

Results:
Nearly half of the participants were obese, 23.3% were overweight and 28% had a normal body mass index. Based on WC and waist-to-height ratio (WHtR), 84% and 79.3% of the participants had metabolic risk, respectively. Over half of the participants were physically inactive. Predominantly, low-intensity activities (yoga, slow walking) were performed as it was assumed to be sufficient. The main motivators of physical activity/exercise behavior were health scare, health benefits, weight loss, availability of resources at convenient time, and better looks. The chief barriers for exercise behavior were lack of motivation, weather, safety concerns, and lack of time.

Conclusion:
Despite over two-third of participants being overweight/obese, 90% of the physically active participants failed to meet the World Health Organization recommendations. Government, community, and individual participation are imperative to formulate interventions strategies to reduce the barriers to physical activity.
Effect of nutrition education package on dietary modification and anthropometry among attendees of a noncommunicable disease clinic at a rural primary health-care facility in Delhi
Authors: Katre Rohit , Banerjee Bratati , Lal Panna , Sharma Pragya 
Published: April 2023

Context:
The global burden and threat of noncommunicable diseases (NCDs) constitutes a major public health challenge that undermines social and economic development throughout the world. NCDs are one of the leading causes of adult morbidity and mortality globally. The disease burden in India due to NCDs has increased from 30% to 55% between 1990 and 2016.

Aims:
We aimed to assess the effect of nutrition education intervention on dietary awareness, practices, and anthropometry.

Settings and Design:
This design was a facility-based before-and-after intervention study without control.

Materials and Methods:
This study was conducted in five phases: planning and recruitment, preintervention, intervention, washout, and postintervention. Data were collected using a pretested, semi-structured interview schedule under the following heads – personal, sociodemographic, and behavioral risk factors of NCDs. Anthropometric examination included weight, height, waist, and hip circumference measurement.

Statistical Analysis:
Collected data were entered into MS Excel and analyzed using IBM SPSS 25 for descriptive and inferential statistics.

Results:
There was a significant increase in mean score for dietary practices and knowledge regarding different food items in the study group. The mean number of servings of fruits and vegetables increased significantly following intervention in the study group (P = 0.001). Significant change in body mass index before and after intervention was found to be in the age group of >60 years (P = 0.041).

Conclusions:
The study has shown the usefulness of intervention aimed at improving dietary behavior among patients of NCDs. With growing burden, there is a need for such innovative and cost-effective measures for halting the rising burden.
