AbstractHow cells coordinate morphogenetic cues and fate specification during development remains a fundamental question in organogenesis. The mammary gland arises from multipotent stem cells (MaSCs), which are progressively replaced by unipotent progenitors by birth. However, the lack of specific markers for early fate specification has prevented the delineation of the features and spatial localization of MaSC-derived lineage-committed progenitors. Here, using single-cell RNA sequencing from E13.5 to birth, we produced an atlas of matched mouse mammary epithelium and mesenchyme and reconstructed the differentiation trajectories of MaSCs toward basal and luminal fate. We show that murine MaSCs exhibit lineage commitment just prior to the first sprouting events of mammary branching morphogenesis at E15.5. We identify early molecular markers for committed and multipotent MaSCs and define their spatial distribution within the developing tissue. Furthermore, we show that the mammary embryonic mesenchyme is composed of two spatially restricted cell populations, and that dermal mesenchyme-produced FGF10 is essential for embryonic mammary branching morphogenesis. Altogether, our data elucidate the spatiotemporal signals underlying lineage specification of multipotent MaSCs, and uncover the signals from mesenchymal cells that guide mammary branching morphogenesis.

Published: May 2024

Purpose:
In this validation study, we examined the factor structure of the mediated learning observation (MLO) used during the teaching phase of dynamic assessment. As an indicator of validity, we evaluated whether the MLO factor structure was consistent across children with and without developmental language disorder (DLD).

Method:
Two hundred twenty-four children (188 typically developing and 36 DLD) from kindergarten to second grade completed a 30-min individual mediated learning session on narrative production. Performance during the session was rated using the 12-item MLO by clinicians on affect, behavior, arousal, and elaboration. Exploratory and confirmatory factor analyses were conducted to establish the factor structure and reliability of the MLO.

Results:
Factor analysis of the MLO suggested a stable three-factor model with adequate fit indices across kindergarten and school-age samples, across both typically developing and DLD subgroups with good to excellent reliability. The final 11-item MLO (one item was removed due to low factor loading) comprises three subscales including (a) cognitive factor, (b) learning anticipation, and (c) learning engagement.

Conclusions:
The MLO is a valid and reliable instrument for assessing language learning skills in children with and without DLD during dynamic assessment. Practical implications and suggestions for future research addressing the utilization of MLO in dynamic assessment are provided.
Transcription Decisions of Conjoined Independent Clauses Are Equitable Across Dialects but Impact Measurement Outcomes
Authors: Oetting Janna B. , Maleki Tahmineh 
Published: May 2024

Purpose:
Transcription of conjoined independent clauses within language samples varies across professionals. Some transcribe these clauses as two separate utterances, whereas others conjoin them within a single utterance. As an inquiry into equitable practice, we examined rates of conjoined independent clauses produced by children and the impact of separating these clauses within utterances on measures of mean length of utterance (MLU) by a child's English dialect, clinical status, and age.

Method:
The data were archival and included 246 language samples from children classified by their dialect (African American English or Southern White English) and clinical status (developmental language disorder [DLD] or typically developing [TD]), with those in the TD group further classified by their age (4 years [TD4] or 6 years [TD6]).

Results:
Rates of conjoined independent clauses and the impact of these clauses on MLU varied by clinical status (DLD < TD) and age (TD4 < TD6), but not by dialect. Correlations between the rate of conjoined clauses, MLU, and language test scores were also similar across the two dialects.

Conclusions:
Transcription decisions regarding conjoined independent clauses within language samples lead to equitable measurement outcomes across dialects of English. Nevertheless, transcribing conjoined independent clauses as two separate utterances reduces one's ability to detect syntactic differences between children with and without DLD and document syntactic growth as children age.

Context. The measurement of pulsar pulse times-of-arrival (ToAs) is a crucial step in detecting low-frequency gravitational waves. To determine ToAs, we can use template-matching to compare each observed pulse profile with a standard template. However, using different combinations of templates and template-matching methods (TMMs) without careful consideration can lead to inconsistent results.
Aims. In pulsar timing array (PTA) experiments, distinct ToAs from the same observations can be obtained due to the use of diverse templates and TMMs. In other words, employing diverse approaches can yield different timing results and would thus have a significant impact on subsequent gravitational wave searches. In this paper we examine several commonly used combinations to analyze their effect on pulse ToAs.
Methods. We evaluated the potential impact of template and TMM selection on 13 typical millisecond pulsars within the European PTA. We employed pulsar timing methods, specifically the root mean square and reduced chi-square (χ2r) of the residuals of the best timing solution, to assess the outcomes. Additionally, we evaluated the system-limited noise floor (SLNF) for each pulsar at various telescopes operating around 1.4 GHz using frequency-resolved templates.
Results. Our findings suggest that utilizing data-derived and smoothed templates in conjunction with the Fourier-domain with Markov chain Monte Carlo TMM is generally the most effective approach, though there may be exceptions that require further attention. Furthermore, we determine that pulse phase jitter noise does not significantly limit the current precision of the European PTA’s timing, as jitter levels derived from other studies are much lower than the SLNF.
La complexité au fondement de la pédopsychiatrie
Authors: Tandonnet Louis 
Published: May 2024

Aujourd’hui la pédopsychiatrie apparaît comme un champ d’opposition entre différents rationalismes scientifiques. S’y ajoute une défiance croissante envers la subjectivité des cliniciens et plus largement envers leur « appareil sémiologique » c’est à dire tout l’édifice institutionnel, de pratique et de pensée qui les entoure. Historiquement, cette remise en question du raisonnement médical renvoie à un débat ancien qui traverse l’ensemble de la Médecine depuis les Lumières. Pour y répondre, la pédopsychiatrie, consciente de la complexité de son objet d’intérêt – les phénomènes mentaux, le développement, la personne humaine, la société – a construit un « appareil sémiologique » susceptible d’appréhender cette complexité. Il associe éclectisme pluridisciplinaire, appréhension dynamique des trajectoires bio-psycho-sociales et soucis de la rencontre clinique. Nous articulerons ces éléments avec trois principes qui décrivent les objets complexes.
A systematic synthesis and analysis of English-language Shuōwén scholarship
Authors: Qin Melissa Xiaohui 
Published: May 2024

AbstractThis study documents the past and present of English scholarship of Shuōwén jiězì, the most important masterpiece of classical Chinese philology and lexicography. In an attempt to investigate the current status (synchronically) and developmental trajectory (diachronically) of Shuōwén scholarship, this study surveyed the bibliographical, theoretical, methodological and thematic state of Shuōwén literature manifested in an analytical framework of six parameters (geographic distribution, publication outlets, citations, theoretical approaches, research methods and research strands) by adopting a thorough bibliometric analysis subsequent to meticulous coding in terms of these six parameters in Shuōwén scholarship. The results showed that Shuōwén scholarship has displayed distinctive distribution patterns and chronological trends along bibliographical, theoretical, methodological and thematic dimensions. Synchronically, the research output is regionally based, thematically restricted and qualitatively examined; diachronically, the research quality is fluctuating, though research quantity multiplies steadily. To look ahead, the study sketched a few directions for advancement of future research agendas: a more global profile of researchers, a larger degree of internationalization of the native circle, a wider disciplinary range, and increased specialization streamlined into data-driven approach to core issues of liùshū, bùshǒu and GPS (graphic-phonetic-semantic) of head graphs. The study is useful in portraying an overarching disciplinary landscape for Shuōwén research and providing the basic reference statistics for possible comparisons across classical Chinese studies and for more general conclusions about the state of scholarship on sinology.

AbstractIn Malaysia’s rapid economic growth and industrialization, environmental degradation and carbon emissions pose significant challenges. As urbanization continues to rise, there is a growing recognition of the imperative to tackle CO2 emissions. Trade openness and globalization drive economic activity but also heighten environmental pressures, including CO2 emissions from transportation and industry. Information communication technology (ICT) usage, shaped by infrastructure and regulations, can either improve energy efficiency or increase energy consumption. The study examines the impacts of economic growth (EG), trade openness (TON), technological innovation (TIN), and ICT on CO2 emissions in Malaysia, using both symmetric and asymmetric methods from 1985 to 2021. While many studies have explored environmental degradation, focusing on CO2 emissions and ecological footprint indicators, only a limited number have delved into the combined impact of sustainable EG, TON, ICT, and TIN on Malaysia’s CO2 emissions. Notably, these studies have often neglected the utilization of both symmetric and asymmetric methodologies. Hence, this study employed auto-regressive distributed lag (ARDL) and non-linear ARDL approaches to investigate the dynamic effects of the studied variables. The key findings from the symmetric analysis demonstrate that EG, TON, and ICT together take part in the increase of CO2 emissions in both the short and long run. Particularly, technological innovation plays a significant role in reducing CO2 emissions in the short term through the adoption of cleaner technologies. However, the results of the NARDL bound test reveal asymmetric long-term consequences of technological innovation, economic growth, and ICT on CO2 emissions. The study underscores the need for CO2 reduction policies in Malaysia, advocating for measures, such as incentivizing cleaner technologies and upgrading energy infrastructure. It also recommends implementing carbon pricing mechanisms for production and trade, alongside awareness campaigns to foster behavioral changes aimed at reducing emissions.
Keeping balance between loyalty and modification: a Toulminian model as analytical framework
Authors: Liu Donghong , Xiong Minghui 
Published: May 2024

AbstractToulmin model has been widely applied to composition-rhetoric and several modified models have been advanced. However, those modified versions diverge widely from Toulmin model. To Keep loyalty to Toulmin’s argumentation and infuse van Eemeren et al.’s pragma-dialectic view, we propose a new modified model as an analytical framework for argumentative essays, with the assumption that a writer is in fact arguing with a potential reader who holds a different view. The proposed framework was applied to explore the Chinese writers’ argumentative essays with content analysis employed. Altogether 60 essays were selected, coded, and analyzed. The results show that the Chinese writers preferred parallel arguments (i.e., several arguments supporting the same claim with the same ground-warrant structure) to hierarchical ones, justification to opposition, and descriptive warrant to the other types. Moreover, the adult expert writers wrote more warrants and qualifiers than the novice writers. The results reveal Chinese rhetoric and writing conventions, and prove the effectiveness of our proposed analytical framework.
Mid-infrared optical coherence tomography with MHz axial line rate for real-time non-destructive testing
Authors: Yagi Satoko , Nakamura Takuma , Hashimoto Kazuki , Kawano Shotaro , Ideguchi Takuro 
Published: May 2024

Non-destructive testing (NDT) is crucial for ensuring product quality and safety across various industries. Conventional methods, such as ultrasonic, terahertz, and x-ray imaging, have limitations in terms of probe-contact requirement, depth resolution, or radiation risks. Optical coherence tomography (OCT) is a promising alternative to solve these limitations, but it suffers from strong scattering, limiting its penetration depth. Recently, OCT in the mid-infrared (MIR) spectral region has attracted attention with a significantly lower scattering rate than in the near-infrared region. However, the highest reported A-scan rate of MIR-OCT has been 3 kHz, which requires long data acquisition time to take an image, unsatisfying industrial demands for real-time diagnosis. Here, we present a high-speed MIR-OCT system operating in the 3–4 µm region that employs the frequency-swept spectrum detection in OCT technique based on time-stretch infrared spectroscopy. By integrating a broadband femtosecond MIR pulsed laser operating at a repetition rate of 50 MHz, we achieved an A-scan rate of 1 MHz with an axial resolution of 11.6 µm, a 10 dB roll-off depth of about 700 µm, and a sensitivity of 55 dB. As a proof-of-concept demonstration, we imaged the surface of substrates covered by highly scattering paint coatings. The demonstrated A-scan rate surpasses previous state of the art by more than two orders of magnitude, paving the way for real-time NDT of industrial products, cultural assets, and structures.
The convergence of public sphere and state advocacy
Authors: Li Xi 
Published: May 2024

Abstract
In 2021, China’s entertainment industry experienced a series of unusual argumentative controversies followed by
the creation of the Qing Lang movement initiated by the Chinese government that called for tackling irregularities in the
industry. With strong support from the Chinese public, the Qing Lang movement presents an intriguing case to examine a new model
of social argument representing both the public and state interest in resolving social problems in the Chinese version of the
public sphere. The paper identifies key characteristics defining a reciprocal model of social activism in state-sponsored actions
in China exemplified by the Qing Lang movement. The paper also argues for the value of a culture-specific approach to
understanding public sphere and social activism and clarifies the function of argument in Chinese society.
Capturing the situated, dynamic nature of EMI-lecture listening comprehension in real time
Authors: Ducker Nathan 
Published: May 2024

Abstract
English-medium instruction (EMI) potentially offers pedagogical efficiency by simultaneously providing access to
academic content and English affordances. EMI’s efficacy and effectiveness, however, remain unproven with questions concerning
students’ language proficiency unresolved. As listening to lectures holds a central role in tertiary education and the development
of language skills is founded on second-language listening ability, key concerns for stakeholders are knowing how much of an EMI
lecture students can understand and what factors impact their lecture listening comprehension. Current methodologies used to
capture listening comprehension data, such as tests, surveys, summaries, and transcript markings do not capture the idiosyncratic,
volatile, and multifaceted reactions to aural text phenomena that learners encounter during a lecture. This study, therefore, uses
an innovative foot switch mechanism to capture comprehension data in real time as students participated in an EMI lecture. These
data were then used to guide a stimulated recall. The data showed learners failing to comprehend extensive sections of the lecture
while deeper analysis identified sections of the lecture where issues concerning prior taught knowledge, top-down schema building,
lexical, and bottom-up identification of sounds coincided for multiple learners. Extrapolating from these points of convergence,
pedagogical recommendations are provided.
English for specific purposes in surging English-medium instruction contexts
Authors: Galloway Nicola , Sahan Kari , McKinley Jim 
Published: May 2024

Abstract
English-medium instruction (EMI) research increasingly reports on students’ language-related challenges and a lack
of academic and language support classes, collaboration between content and language teachers and overall teacher training. Our
study explores EMI in Japan and China, two contexts where EMI has been referred to as emerging but is now “surging.” In these
contexts, EMI is closely linked to English language proficiency goals, yet research on supporting students remains scarce. Data
were collected via interviews and focus groups with students, English teachers and content teachers, who provided insights into
approaches to EMI policy implementation, stakeholders’ attitudes, and the need for English for specific purposes (ESP) and English for specific academic purposes (ESAP). The results provide much needed insights for evidence-informed EMI policy implementation,
curriculum development and teacher training. The study also provides insights into institutional infrastructure conducive to EMI
policy, with findings revealing ESP needs of EMI students and the training needs of teaching staff. The study presented in this
paper furthers the work that has been conducted in Anglophone settings on the complexity of ELT practitioner roles. The results
also provide directions for future research.
Notation and phonology of the Tri language in Vilabouly*

Published: May 2024

Abstract
Gérard Diffloth (1937–2023) was a leading authority on Austroasiatic languages, with a wide range of linguistic
interests ranging from historical reconstruction to expressives, and much more. He was a tireless fieldworker who firmly believed
that research into the linguistic history of Austroasiatic need be grounded in long-term fieldwork with native speakers in their
daily speech environment. In this paper we introduce an unpublished manuscript on the phonology of the Tri language spoken in
Vilabouly District, Savannakhet Province in southern Laos. We frame this with a brief introduction to his work, with a tribute to
his commitment to fieldwork and the principles he maintained throughout the many decades of working with speakers of Austroasiatic
languages.

Optical characterization of nanosecond-pulsed discharge in liquid nitrogen
Authors: Dobrynin Danil , Song Zhiheng , Fridman Alexander 
Published: May 2024

Abstract
We report the optical characterization of nanosecond-pulsed plasma ignited directly in liquid nitrogen. Using imaging and optical emission spectroscopy, we estimate neutral temperatures and densities, as well as local electric field values, and the obtained results indicate that the discharge develops via streamer (‘electronic’) mechanism. We show that millimeter-scale plasma propagates in liquid nitrogen at velocities of ∼500 km s−1 with the corresponding required local electric fields as high as 25 MV cm−1, while the estimated local electric fields in the ‘core’ of the discharge are around 6–8 MV cm−1 (corresponding to reduced electric field values of 600–1000 Td). The neutral and electron densities in the ‘main body’ of the discharge were estimated using broadened argon lines, indicating that the neutral densities in the near-electrode region are around 1020 cm−3 (tens of atmospheres), while the maximum recorded temperature is just a few tens of degrees above the surrounding liquid. Electron densities were estimated to be ∼1017 cm−3, about two orders of magnitude lower than those measured for water discharge.
Recent advances in electromagnetic metamaterials and metasurfaces for polarization manipulation
Authors: Shao Linda , Zhu Weiren 
Published: May 2024

Abstract
We review the recent developments in the field of electromagnetic metamaterials and metasurface for polarization manipulation, focusing on their operation principles and practical applications. We discussed the research progress of chiral metamaterials and anisotropic metasurfaces, and also summarized the achievements of metasurfaces for comprehensive manipulation polarization and phase in recent years. We further summarize the recent achievements on the diversified polarization manipulation functions of metasurfaces. Finally, we discuss reconfigurable metasurfaces that can dynamically control the polarizaiton and wavefronts of electromagnetic waves, including not only electrically reconfigurable metasurfaces with constitutional meta-atoms locally tuned by external stimuli, but also time-modulated metasurfaces exploiting the temporal dimension by applying dynamic switching of the coding sequences. Finally, we look forward to the possible future directions and existing challenges in this rapidly developing field.
