Which stress is on response particles? An empirical study
Authors: Mohammadi Maryam 
Published: April 2023

Polar response particles (PRPs) have been the subject of a variety of studies in semantics and pragmatics, especially in languages like English and Farsi, where the same particles, āre ‘Yes’ and na ‘No’, can be used with two readings, namely the polarity and the (dis)agreement readings. While PRPs in response to the negative questions result in ambiguity, many scholars mention the important role of the prosodic saliency in the positive answers to the negative questions. This paper is an empirical effort to capture the focal stress on PRPs in Farsi. Two experiments were conducted with respect to the polarity and the bias of the question. The first experiment confirms the earlier studies for the presence of focal stress on the opposi- tion answers to the negative questions, as well as the lack of such stress in response to the positive questions. The second experiment reveals the presence of focal stress in response to both positive and negative questions, when the questions necessarily express bias. I will propose that two types of focal stress, namely Contrastive Focus and Verum Accent, perform two different functions. In the first experiment, the con- trastive focus helps to disambiguate PRPs when required, while the Verum accent in the second study is to indicate the conflict between the addressee’s response and the speaker’s (bias) expectation.
The morpho-phonology of an English diminutive
Authors: Davis Colin P. B. 
Published: April 2023

I describe and analyze the morpho-phonology of the English diminutive suffix /-i/, as in doggy, birdie, horsie, and so on. My first goal is to argue that unlike most other diminutives in English this suffix is productive, though subject to a phonological constraint. Specifically, I show that this suffix must be adjacent to a stressed syllable—a requirement that motivates exceptional truncations. I propose that thesefacts provide a clear instance of a morpheme-specific phonological constraint. My second goal is to examine how this diminutive interacts with nouns that normally have irregular plural forms. I show that this diminutive can block irregular plural morphology, but optionally allows the persistence of plural ablaut. I explain these facts using an analysis in which morphological rules require adjacency between the triggering node and the affected one, along with a proposal that the English diminutive /-i/ is an adjunct/modifier which can be attached late in the derivation.
‘Again’ separation in Italian
Authors: Liu Yuyang 
Published: April 2023

In Italian, ri- ‘again’ can be separated from the constituent it is semantically attached to and challenges the structural account for the ambiguity of ‘again’-type elements. To address this issue, this paper proposes a solution through aspectual agreement and suggests a movement and reconstruction analysis for the separation effect of ri-. It also provides supporting evidence for this analysis through Coordinate Structure Constraint and Relativized Minimality.
Exploring the effect of stress on gestural coordination
Authors: Gu Yunting 
Published: April 2023

In this study, I examined stress in speech production within the framework of Articulatory Phonology. Specifically, I tested the hypothesis that stress could be analyzed as a prosodic gesture. Using articulatory data from an English corpus, I found that the CV lag–the gestural lag between a consonant and a vowel–of stressed syllables is significantly larger in terms of both duration and proportion than that of unstressed syllables. I also found that stressed consonant and vowel gestures are longer than unstressed ones. These findings seem to suggest that stress could be analyzed as a prosodic gesture. Moreover, my study reveals a source of variation in CV coordination, which can inform other kinematic studies.

Abstract
Stellar coronal mass ejections (CMEs) have recently received much attention for their impacts on exoplanets and stellar evolution. Detecting prominence eruptions, the initial phase of CMEs, as the blueshifted excess component of Balmer lines is a technique to capture stellar CMEs. However, most of prominence eruptions identified thus far have been slow and less than the surface escape velocity. Therefore, whether these eruptions were developing into CMEs remained unknown. In this study, we conducted simultaneous optical photometric observations with Transiting Exoplanet Survey Satellite and optical spectroscopic observations with the 3.8 m Seimei Telescope for the RS CVn-type star V1355 Orionis that frequently produces large-scale superflares. We detected a superflare releasing 7.0 × 1035 erg. In the early stage of this flare, a blueshifted excess component of Hα extending its velocity up to 760–1690 km s−1 was observed and thought to originate from prominence eruptions. The velocity greatly exceeds the escape velocity (i.e., ∼350 km s−1), which provides important evidence that stellar prominence eruptions can develop into CMEs. Furthermore, we found that the prominence is very massive (9.5 × 1018 g < M < 1.4 × 1021 g). These data will clarify whether such events follow existing theories and scaling laws on solar flares and CMEs even when the energy scale far exceeds solar cases.

Published: April 2023

Abstract
Identifying and characterizing young populations of star-forming regions are crucial to unraveling their properties. In this regard, Gaia-DR3 data and machine-learning tools are very useful for studying large star-forming complexes. In this work, we analyze the ∼7.1 deg2 area of one of our Galaxy’s dominant feedback-driven star-forming complexes, i.e., the region around Trumpler 37. Using the Gaussian mixture and random-forest classifier methods, we identify 1243 highly probable members in the complex, of which ∼60% are new members and are complete down to the mass limit of ∼0.1–0.2 M
⊙. The spatial distribution of the stars reveals multiple clusters toward the complex, where the central cluster around the massive star HD 206267 reveals two subclusters. Of the 1243 stars, 152 have radial velocity, with a mean value of −16.41 ± 0.72 km s−1. We investigate stars’ internal and relative movement within the central cluster. The kinematic analysis shows that the cluster’s expansion is relatively slow compared to the whole complex. This slow expansion is possibly due to newly formed young stars within the cluster. We discuss these results in the context of hierarchical collapse and feedback-induced collapse mode of star formation in the complex.

Abstract

(5100 Å) = 4.7 × 1044 erg s−1) SDSS J141041.25+531849.0 at z = 0.359 with 127 spectroscopic epochs over nine years of monitoring (2013–2022). We observe anticorrelations between the broad emission-line widths and flux in all three emission lines, indicating that all three broad emission lines “breathe” in response to stochastic continuum variations. We also observe dramatic radial velocity shifts in all three broad emission lines, ranging from Δv ∼ 400 km s−1 to ∼800 km s−1, that vary over the course of the monitoring period. Our preferred explanation for the broad-line variability is complex kinematics in the gas in the broad-line region. We suggest a model for the broad-line variability that includes a combination of gas inflow with a radial gradient, an azimuthal asymmetry (e.g., a hot spot), superimposed on the stochastic flux-driven changes to the optimal emission region (“line breathing”). Similar instances of line-profile variability due to complex gas kinematics around quasars are likely to represent an important source of false positives in radial velocity searches for binary black holes, which typically lack the kind of high-cadence data we analyze here. The long-duration, wide-field, and many-epoch spectroscopic monitoring of SDSS-V BHM-RM provides an excellent opportunity for identifying and characterizing broad emission-line variability, and the inferred nature of the inner gas environment, of luminous quasars.
Exploring the Connection between Helioseismic Travel Time Anomalies and the Emergence of Large Active Regions during Solar Cycle 24
Authors: Stefan John T. , Kosovichev Alexander G. 
Published: April 2023

Abstract
We investigate deviations in the mean phase travel time of acoustic waves preceding the emergence of 46 large active regions observed by the Helioseismic and Magnetic Imager. In our investigation, we consider two different procedures for obtaining the mean phase travel time, by minimizing the difference between cross-correlations and a reference, as well as the Gabor wavelet fitting procedure. We cross-correlate the time series of mean phase travel time deviations with the surface magnetic field and determine the peak correlation time lag. We also compute the perturbation index—the area integrated mean phase travel time deviations exceeding quiet Sun thresholds—and compare the time of peak perturbation index with the correlation time lag. We find that the lag times derived from the difference minimization procedure precede the flux emergence for 36 of the 46 active regions, and that this lag time has a noticeable correlation with the maximum flux rate. However, only 28 of the active regions have peak perturbation index times in the range of 24–48 hr prior to the flux emergence. Additionally, we examine the relationship between the properties of the emerged active regions and the strength of helioseismic signals prior to their emergence.

Abstract
We utilize ∼17,000 bright luminous red galaxies (LRGs) from the novel Dark Energy Spectroscopic Instrument Survey Validation spectroscopic sample, leveraging its deep (∼2.5 hr galaxy−1 exposure time) spectra to characterize the contribution of recently quenched galaxies to the massive galaxy population at 0.4 < z < 1.3. We use Prospector to infer nonparametric star formation histories and identify a significant population of recently quenched galaxies that have joined the quiescent population within the past ∼1 Gyr. The highest-redshift subset (277 at z > 1) of our sample of recently quenched galaxies represents the largest spectroscopic sample of post-starburst galaxies at that epoch. At 0.4 < z < 0.8, we measure the number density of quiescent LRGs, finding that recently quenched galaxies constitute a growing fraction of the massive galaxy population with increasing look-back time. Finally, we quantify the importance of this population among massive (

Published: April 2023

Biological invasions are one of the major threats to the ecosystem structure and functioning. After the initial introduction, frequently mediated by human activities, alien species can overcome different biogeographical and ecological barriers and determine severe impacts on native biodiversity and socio-economic activities. The Italian peninsula is located at the intersection of large trade routes within the Mediterranean Sea. Such position, along with the intense commercial activity and the high population density of the Italian coast, are considered important drivers of alien species in Italian marine and transitional ecosystems. The Italian peninsula, however, is also one of the regions with the highest native species richness within the Mediterranean Sea and, therefore, it is crucial to account for both alien and native species diversity when estimating the impact of biological invasion. Yet, such comprehensive information is frequently scattered across several biodiversity information systems and databases.
Here, two datasets with alien and native species records in Italian marine and transitional waters are described. These datasets, created for the LifeWatch Italy case study on alien species, are the result of a large-scale collaboration involving experts working across the whole range of taxonomic diversity. The marine dataset includes a total of 12,219 records belonging to 3,772 species gathered from 91 investigated sites and seven EUNIS habitats. The dataset on transitional waters biodiversity includes 3,838 records belonging to 2,019 species found in 23 locations and four EUNIS habitats. Alien species were recorded in both marine and transitional waters, accounting respectively for 140 and 171 biological records belonging to 59 and 97 species. These occurrence data can be used for further research studies or management purposes, including the evaluation of the invasion risk and the formulation of alien species control and management plans. Furthermore, these compiled datasets can be used as input data for the Biotope vulnerability case study of LifeWatch ERIC, which offers a number of ICT services for the calculation of the incidence and of the impact of alien species on European biotopes.
Performance Analysis for 3D Reconstruction Objects in Meshroom and Agisoft—A Comparative Study
Authors: Enesi Indrit , Kuqi Anduel 
Published: April 2023

3D reconstruction of objects is with ​​interest nowadays, mainly in production industry. The main challenge of them is accuracy and processing time, especially for small and detailed objects. The field of photogrammetry realizes the 3D reconstruction of objects through 2D photos. Different software, free or non-free exists, providing different quality and performance. Accurate 3D reconstruction is important in cloning objects, especially in the industry of spare parts or in the production of prostheses in medicine, etc. Determining accurately the sizes of the object, especially those with complex geometric shapes is very important in the 3D printing process.
The purpose of this paper is the analysis of the performance of 3D reconstruction in terms of accuracy for objects of different sizes regarding the number of its photos and the time evaluation of this process. The 3D reconstruction will be performed by free software Meshroom, measurement will be done in MeshLab and non-free software Agisoft. Experimental results show that quality and performance of 3D reconstruction depends on the number of photos of the object, concluding in finding the optimal balance between these parameters. By comparing obtained results from MeshRoom and Meshlag versus Agisoft, it is claimed that Agisoft performs better than MeshRoom. It offers more optimization techniques, reduces processing time, more visual quality in the reconstructed 3D object as well as more accuracy in measurement.

Published: April 2023

Cet article propose de présenter le débat d’idées comme une forme particulière d’« action conjointe », à la fois révélatrice de ses descripteurs fondateurs et productrice de modalités particulières d’interactions fondées sur les échanges contradictoires entre élèves. Largement utilisée en EPS dans l’enseignement des sports collectifs en France, cette organisation pédagogique consiste en une situation dans laquelle les élèves s’expriment (verbalisation audible) et échangent des faits et des idées (verbalisation partagée), sur la base d’observations ou d’activités personnelles vécues dans le jeu (verbalisation consécutive). Le débat d’idées, comme situation didactique favorise les apprentissages par l’élaboration d’actions en projet et la construction de connaissances en situation d’opposition. À l’appui de plusieurs études empiriques présentées dans le cadre de cet article, nous soulignons l’efficacité du dispositif en termes d’évolution des réponses des élèves et des progrès dans leurs acquisitions tout en identifiant certaines conditions qui en limitent la pleine expression en termes d’égalité d’accès aux savoirs scolaires.

We report a family cluster of six members who tested positive for SARS-CoV-2 infection in April 2021 at University Hospital, Kotelawala Defence University, Sri Lanka. Samples from three members were subjected to Next Generation Sequencing (NGS) and all were identified as SARS-CoV-2 variant of pangolin lineage C.36, containing the L452R mutation which is associated with high infectivity. All patients recovered with mild symptoms and no complications. This is the first report identifying a new variant of the C.36 lineage containing the L452R mutation from Sri Lanka followed by detection of the same lineage from Northern Sri Lanka in June 2021 and no reported cases hereafter. At that time, it was relatively rare for a whole family to get infected, and the concern was that this strain would spread rapidly. Due to unknown circumstances it never spread to be detected by the national surveillance programme. Other variants, B.1.411 and B.1.1.7, more dominant and infectious, were already in circulation and presumably outcompeted this strain.

Constitutional Human Rights Of Transgender Persons In Pakistan: A Linguistic And Social Inquiry
Authors: Malik Sadia , Ijaz Umair , Khan Asra 
Published: April 2023

This paper aims to investigate the lexical choices made in the Constitution to represent gender, the granted constitutional human rights of transgender persons, and contradictory social practices from the perspective of making them powerless and marginalized in terms of non-gender binary. The quantitative analysis of the second section of the Constitution related to human rights and principles of policy for government in terms of nouns and personal pronouns to represent generic pronouns and its implication for gender representation in a legal document was carried out through simple concordance program 4.0.5 by generating word list of data to find the frequencies. Moreover, the basic human rights of dignity, education, health care, financial security, employment opportunities, and equality in all respects ensured to all the citizens of state are discussed and social realizations of these rights for transgender are explored. The findings reveal that transgender persons neither have any representation in the Constitution of Pakistan nor they are the recipients of basic human rights in Pakistani society as compared to other marginalized groups like women, children and differently able people. To conclude, it can be said that although in the last decade, governments have passed some policies (Transgender Persons Welfare Policy, 2018) to empower Transgender community, yet, a long-term nation based social awareness program and implementation of policies are recommended to make transgender persons’ lives better in letter and spirit.
