Bilingual Children Demonstrate Variation Within Shared Narrative Macrostructure
Authors: Granados Vargas Alejandro , Peña Elizabeth D. , Bedore Lisa M. 
Published: October 2024

Aims:
We investigate the relationship between narrative macrostructure, current language exposure, and microstructure in second-grade Spanish–English bilingual children in the United States. Macrostructure knowledge has been claimed to be shared across languages in multilingual individuals. We examine the role of current language exposure and microstructure on macrostructure and how individual children organize their stories in English and Spanish. We use sociocultural theory to investigate differences in the macrostructural elements children choose to include in their stories by language.

Methodology:

Using existing data, we used a two-sample
t
-test to compare average macrostructure and microstructure performance in English and Spanish in addition to performance on subcomponents of macrostructure. A correlational analysis was used to compare narrative performance in both languages. We used regression analysis to investigate to what extent current language exposure and microstructure influenced the macrostructure of 62 Spanish–English bilingual second graders' stories.

Results:
Children used more words and a greater variety of words in Spanish compared to English. However, they demonstrated comparable use of overall macrostructure across languages, in addition to variation in what macrostructure subcomponents they use by language of story elicitation. No statistically significant relationship was found between current language exposure and macrostructure, except for Spanish story structure. Correlational analysis revealed a significant relationship between macrostructure performance in English and Spanish. A significant relationship was found within languages between microstructure and macrostructure and across languages between Spanish microstructure and English internal state terms.

Discussion:
Findings are consistent with extant literature that claims macrostructure is shared across languages. Children require lexical diversity across languages to express their ideas organized within macrostructural elements. Although bilingual children tell comparably complex stories, they may be making culturally and linguistically specific decisions about what macrostructure components to include in their stories.
Cortical Tracking of Speech Is Reduced in Adults Who Stutter When Listening for Speaking
Authors: Gastaldon Simone , Busan Pierpaolo , Molinaro Nicola , Lizarazu Mikel 
Published: October 2024

Purpose:
The purpose of this study was to investigate cortical tracking of speech (CTS) in adults who stutter (AWS) compared to typically fluent adults (TFAs) to test the involvement of the speech-motor network in tracking rhythmic speech information.

Method:
Participants' electroencephalogram was recorded while they simply listened to sentences (listening only) or completed them by naming a picture (listening for speaking), thus manipulating the upcoming involvement of speech production. We analyzed speech–brain coherence and brain connectivity during listening.

Results:
During the listening-for-speaking task, AWS exhibited reduced CTS in the 3- to 5-Hz range (theta), corresponding to the syllabic rhythm. The effect was localized in the left inferior parietal and right pre/supplementary motor regions. Connectivity analyses revealed that TFAs had stronger information transfer in the theta range in both tasks in fronto-temporo-parietal regions. When considering the whole sample of participants, increased connectivity from the right superior temporal cortex to the left sensorimotor cortex was correlated with faster naming times in the listening-for-speaking task.

Conclusions:
Atypical speech-motor functioning in stuttering impacts speech perception, especially in situations requiring articulatory alertness. The involvement of frontal and (pre)motor regions in CTS in TFAs is highlighted. Further investigation is needed into speech perception in individuals with speech-motor deficits, especially when smooth transitioning between listening and speaking is required, such as in real-life conversational settings.

Published: October 2024

AbstractFor citrus trees cultivated by dwarf dense planting, the fruits are randomly distributed in space, which poses difficulties for mechanized picking. To improve picking efficiency, a citrus picking system based on dual robot collaboration is designed and a global scanning picking scheme that scans the entire fruit tree to achieve orderly fruit picking is proposed in this research. The dual‐robot calibration with the iterative method and closed‐form method is completed in the research. The picking problem is attributed to the single traveling salesman problem, and the trajectory planning and the picking task are completed with genetic algorithm in the research. The picking experiments are designed in the research. As a result, in the picking experiments, the average time for planning the picking sequence of citrus was 0.1184 s, the longest time is 0.1560 s. In each group of citrus picking experiments, the total picking time averaged 158.9 s, the longest group took 170 s, the picking success rate is 82%. The picking results show that the built dual‐machine system can effectively complete the picking task and meet the real‐time requirement of picking. The proposed dual‐robot picking system can provide a reference for the establishment of other picking robot system.

Background: The utility and uptake of Del Nido cardioplegia in adult cardiac surgery is rapidly increasing. Cases with prolonged aortic cross-clamp times necessitate multi-dosing however an understanding of safe ischaemic times and definitive guidelines in this domain are lacking. Therefore, this study aimed to assess the safety and efficacy of our DNC strategy by comparing post-operative troponin profiles and clinical outcomes between Del Nido and hyperkalaemic cardioplegia for cases with aortic cross-clamp times of greater than 90 min. Methods: A single-centre, retrospective cohort study at Flinders Medical Centre and Flinders Private Hospital of patients undergoing composite cardiac surgery with a cross-clamp time longer than 90 min. Data was prospectively collected from the Flinders Cardiac Surgery Registry from June 2014 to December 2022. A propensity-matched (1:1) analysis was performed comparing patients receiving Del Nido cardioplegia (n = 194) to those receiving hyperkalemic blood cardioplegia (n = 194). The primary outcome was the postoperative troponin release profile with clinical events reported as secondary outcomes. Results: There was no difference in the peak or median troponin at 6, 12 and 72 h nor the number of patients with positive troponin profiles postoperatively between cohorts. There was no difference in clinical outcomes between groups with aortic cross-clamp times of 90 min which remained true in sensitivity analysis extending out to 120 min. The Del Nido cohort received less cardioplegia volume (p < 0.001) and were more likely to return to spontaneous rhythm (p < 0.002). Conclusion: Del Nido cardioplegia for anticipated aortic cross-clamp times of greater than 90 min provided equivocal post-operative troponin profiles and clinical outcomes compared to multidose hyperkalemic blood cardioplegia.

Published: October 2024

Introduction Lymph nodes, lung, liver, bone, and brain are the commonest metastatic sites for malignancies arising in various body sites. Gastrointestinal (GI) tract is a very uncommon metastatic site and the present study describes the single-center experience of GI metastases from non-GI malignancies.
Aims and Objectives To study the spectrum of metastatic tumors to GI tract and elucidate their clinicopathological characteristics.
Materials and Methods This was a retrospective study done on cases diagnosed from 2015 to 2023 at our institute. All cases of non-GI malignancies metastatic to hollow GI tract were included. Cases with GI primary, hematological malignancies, cases with exclusive serosal deposits, and direct invasion of a GI organ from an adjacent primary tumor were excluded. Apart from hematoxylin & eosin (H&E)-stained slides, immunohistochemistry findings of these were reviewed.
Results Thirty-six patients were histologically proven GI metastases from non-GI malignancies diagnosed during the study period. Most cases were seen in 5th to 7th decade with a significant female preponderance (M:F of 1:8). The commonest metastatic GI sites were small bowel (n = 11), sigmoid colon (n = 9), and rectum (n = 7), followed by stomach (n = 3), appendix (n = 3), gall bladder (n = 2), and ampulla (n = 1). Stricture, perforation, and nodular mucosa were the most common endoscopic findings. The most common primary malignancies in females were ovarian serous carcinoma (n =21) followed by squamous cell carcinoma (SCC) of cervix (n = 8). In males, there was no site preference, and the primary sites included prostate, lung, kidney, and oral mucosa.
Conclusion The study highlights the rare occurrence of GI metastases from non-GI malignancies. Females are at greater risk of such metastases primarily from ovarian serous carcinoma and cervical SCCs.
Not so weak after all: institutional and partisan sources of parliamentary resilience in France and Finland during COVID
Authors: Navarro Julien , Raunio Tapio 
Published: October 2024

AbstractDuring crises, executives are empowered at the expense of legislatures. This applied also to the COVID period. Focusing on two stable yet different European democracies, France and Finland, this article examines the internal and external factors affecting the ability of parliaments to control the executive during the pandemic. The empirical analysis considers institutional developments affecting parliaments as well as the behaviour of MPs. The benefit of hindsight enables us to assess the entire COVID period, showing that in both countries the initial dominance of the executive was followed by more assertive parliamentary behaviour. The results indicate that, despite difficult conditions, parliaments in both countries displayed adaptability and resilience, but power constellations pre-dating the COVID period impacted on the respective roles of the French and Finnish parliaments.
The Fear of Critical Race Methodologies
Authors: Harris Suzanne Temwa Gondwe 
Published: October 2024

AbstractCritical race methodologies (CRM), which prioritise the experiences and knowledge of racialised peoples, have become a useful tool to identify and acknowledge racialised power relations in all aspects of the research process. However, engaging with these methodologies requires researchers to not only move away from western scientific research methodologies, which have historically excluded the knowledges and lived experiences of racialised peoples, but confront the legacy of methodological Whiteness. To explore this further, this article takes a self-reflexive account on why International Non-Governmental Organisations [(I)NGOs], who have a long history of (re)producing harmful images of racialised peoples, fear the adoption of CRM based on this tension. Drawing on Bantu Steve Biko’s and Lewis Gordon’s conceptualisation of racism, fear and Black Consciousness, this paper argues that CRM should not be seen as an attack on methodological Whiteness, but an opportunity to advocate for a sector-wide introspection on the methodological choices which not only centre on the inclusion of marginalised voices, but recognise the need for a redistribution of power to challenge prevailing hierarchies within (I)NGOs.

Published: October 2024

Feedback-insensitive Quantum Dot (QD) comb lasers hold significant promise for integrated dense wavelength division multiplexing photonic systems due to their ability to generate multiple wavelengths and operate without bulky isolators, facilitating the development of high-density and large-scale photonic integrated circuits. In this study, we investigated the optical feedback (OFB) influence of the InAs/GaAs QD comb laser from various perspectives. Our findings reveal that the comb laser exhibits a stable locking region with consistent optical spectra across a range of OFB strengths (−45 to −10 dB). Furthermore, under a high OFB strength of −10 dB, there is a notable 40 dB suppression of relative intensity noise in the low-frequency range (below 1 GHz). Transmission experiments demonstrate clear eye openings at 25 Gbps using a bit pattern of 231-1 pseudorandom binary sequence. Remarkably, the bit error rates decrease by five orders of magnitude under −10 dB OFB. These results indicate the ultra-robustness of 100 GHz grid QD comb laser, which exhibits great transmission enhancement under a strong OFB of −10 dB.

Published: October 2024

Recently, research on wearable devices for physiological exercise monitoring has garnered significant attention. Here, we propose a dual wave-structured triboelectric nanogenerator (DW-TENG) integrated with a cotton cloth, developed for smart running applications. The DW-TENG sensor leverages a flexible wave triboelectric layer composed of polydimethylsiloxane and silicone, with a copper electrode layer between them for sensing. This structure allows for customizable pressure sensitivity by adjusting the silicone hardness. Experimental results show that the DW-TENG achieves a sensitivity of 0.4 V kPa−1, with response and recovery times of 75 and 90 ms, respectively. The sensor effectively measures heart rate changes during various physical activities, including walking, running, and jumping. Electrical performance tests reveal that the DW-TENG’s output is significantly influenced by the silicone hardness, operational frequency, and microstructure height. The DW-TENG sensor demonstrates high durability and stability, maintaining consistent voltage output over 40 000 cycles. This research highlights the potential of the DW-TENG in multifunctional physiological and physical activity monitoring, providing real-time data on respiratory patterns, heart rate, and movement dynamics, thus enhancing athletic training, performance assessment, and health monitoring.

Published: October 2024

Vertical geometry NiO/Ga2O3 heterojunction (HJ) rectifiers and Ni/Au Schottky rectifiers fabricated on the same wafer and each with the same diameter (100 μm) were operated at 77–473 K to compare their capabilities in space-like environments. The HJ rectifiers suffer a 4-order reduction in forward current at 77 K due to the freeze-out of acceptors in the NiO, leading to MIS-type operation. By sharp contrast, the Schottky rectifiers have higher forward current and lower on-resistance at 77 K compared to 298 K due to improved carrier mobility. The on/off ratio of Schottky rectifiers at 77 K becomes similar to HJ rectifiers at 298–473 K. The reverse recovery time of Schottky rectifiers is reduced from 20 ns at 273 K to 16 ns at 77 K, while HJ rectifiers cannot be switched at this temperature. While the latter are superior for high-temperature applications, the former are better suited to cryogenic operation.

Authors: Jia Xiaoping , Jiang Min , Zhou Jing , Ma Cailing 
Published: October 2024

Background To describe the changes in cervical lesions prevalence and high-risk human papillomavirus (HR-HPV) infections from 2012 to 2021, which have never been reported before, to provide direction for the effective implementation of cervical cancer prevention measures. Methods This retrospective study included women aged >25 years who received either organised or opportunistic cervical HR-HPV screening from January 2012 to December 2021 in Karamay Central Hospital, Karamay, China. The patients were split into four groups according to age 25–35, 36–45, 46–55 and >55 years, respectively. The Joinpoint Regression Program was used to analyse the trends of HR-HPV infection and the detection of cervical lesions. Results Data from 85,429 women revealed a decline in HR-HPV infection rates across all age groups from 2012 to 2021. Although HR-HPV infection rates decreased, cervical lesion detection rates increased, although the proportion of cervical cancer in these lesions declined, likely due to enhanced awareness and HPV vaccination in Karamay. From 2012 to 2021, the prevalence of low-grade squamous intraepithelial lesions was 9.70%, and high-grade squamous intraepithelial lesions was 5.85%. HR-HPV infections were highest in the ≥55 years age group, with HPV52 (20.96%) being the most prevalent type. Conclusions In the past 10 years, the prevalence of HR-HPV infection has shown a decreasing trend, whereas the detection prevalence of cervical lesions has shown an upward trend among women in Karamay City. Importantly, particular emphasis should be placed on cervical cancer screening in women aged >55 years.
Electronic Structure Evolution during Martensitic Phase Transition in All-d-Metal Heusler Compounds: The Case of Pd2MnTi
Authors: Li 李 Guijiang 贵江 , Wang 王 Gang 刚 , Liu 刘 Enke 恩克 
Published: October 2024

Abstract
Taking Pd2MnTi as a representative example, we systematically investigate and theoretically reveal the electronic structure evolution during martensitic phase transition in all-d-metal Heusler compounds. The calculation and theoretical analysis suggest that Pd2MnTi is not stable in cubic structure and prone to transform to low-symmetric tetragonal structure. By tetragonal deformation, the shrinkage of lattice parameters and the decrease of symmetry promote the electron accumulation between Pd and its first nearest neighboring Ti atom, resulting in the increasing covalent hybridization. The occurrence of pseudogap in density of states of tetragonal Pd2MnTi near the Fermi level also verifies the enhancement of covalent bond. Comparatively, the stronger interatomic bond in tetragonal Pd2MnTi, i.e., covalent bond here, would strengthen interatomic coupling and consequently lower the energy of the material. By the martensitic phase transition, more stable states in energy are achieved. Thus, based on the analysis of electronic structure evolution, the nature of martensitic phase transition is a process wherein symmetry breaking weakens the original weak chemical bonds in high-symmetric parent phase and induces the strong chemical bond to lower the energy of the materials and to achieve a more stable state. This study could help to deepen the understanding of martensitic phase transition and the exploration of novel materials for potential technical applications.

Published: October 2024

Abstract
This study addresses the issues of insufficient sensitivity and poor reversibility for NO2 detection by successfully fabricating a sensor based on uniform and high-quality few-layer MoS2 polycrystalline material using chemical vapor deposition. This approach aims to improve the response of the sensor by exploiting the abundance of grain boundary (GB) defects in polycrystalline MoS2 membranes. Comprehensive surface morphology analysis of the few-layer MoS2 polycrystalline films was conducted using microscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy to characterize their chemical composition and properties. Subsequently, evaluation of 1–100-ppm NO2 was conducted at room temperature (25 °C). The results show excellent performance of the sensor, with a response range of 11–82.24. Notably, under ultraviolet excitation at room temperature, this sensor exhibits a response time of only 41 s to 50 ppm of NO2 with complete recovery and improved sensitivity, maintaining reliable stability over eight weeks. Furthermore, the findings reveal that the sensor demonstrates high selectivity toward NO2 gas with limit of detection and limit of qualification values of 10 and 34 ppb, respectively. Owing to the abundant adsorption sites provided by GB defects in polycrystalline thin films, the response performance of the sensor is effectively enhanced. This study provides valuable insights into the future design and development of high-performance NO2 gas sensors.
