Published: May 2024

Objective Acute and massive blood loss is fortunately a rare occurrence in perinatal/neonatal practice. When it occurs, typical transfusion paradigms utilize sequential administration of blood components. However, an alternative approach, transfusing type O whole blood with low anti-A and anti-B titers, (LTOWB) has recently been approved and utilized in trauma surgery.
Study Design Retrospective analysis of all perinatal patients who have received LTOWB after acute massive hemorrhage at the Intermountain Medical Center.
Results LTOWB was the initial transfusion product we used to resuscitate/treat 25 women with acute and massive postpartum hemorrhage and five infants with acute hemorrhage in the first hours/days after birth. We encountered no problems obtaining or transfusing this product and we recognized no adverse effects of this treatment.
Conclusion Transfusing LTOWB to perinatal patients after acute blood loss is feasible and appears at least as safe a serial component transfusion. Its use has subsequently been expanded to multiple hospitals in our region as first-line transfusion treatment for acute perinatal hemorrhage.
Key Points
Low-titer type O whole blood (LTOWB) was our initial transfusion product for 30 perinatal patients with acute hemorrhage. Twenty-five of these were obstetrical patients and five were neonatal patients. We encountered no problems with, or adverse effects from LTOWB in any of these patients. LTOWB transfusions to women were ten days since donor draw (interquartile range, 8–13) and to neonates was six days (5–8).
Percutaneous Drainage for Giant Pulmonary Interstitial Emphysema in a Tiny Infant with a Birth Weight of 327 g

Published: May 2024

AbstractGiant pulmonary cyst in extremely low birth weight (ELBW) infants has been described as one of severe pulmonary diseases. Any definitive therapy for refractory cases, where conservative methods of treatments are not effective, has not been established as a standard. Herein, we report an ELBW infant with a giant pulmonary cyst cured by percutaneous drainage without any adverse events. A female infant was born with a birth weight of 327 g. Surfactant was administered on days 1 and 2 of life to treat respiratory distress syndrome. Tracheal intubation was performed and synchronized intermittent mandatory ventilation was promptly initiated following birth. On the course, right giant pulmonary cyst developed on day 9 after birth. Although we started conservative therapy, including right lateral decubitus positioning, high-frequency oscillatory ventilation, and systemic corticosteroid administration, the diameter of the cyst had reached 34 mm, and mediastinal displacement was observed on day 28 after birth when she weighed 393 g. She recovered by percutaneous drainage followed by suction with a pressure of −10 cm H2O under mild sedation for 3 days. We believe that percutaneous drainage can be one of the available options for unilateral pulmonary interstitial emphysema.

AbstractTo illustrate the selections and differences in mathematical problem-posing (MPP) strategies of junior high school students, this study constructs a theoretical framework for mathematical problem-posing strategies and then conducts an empirical study through a survey of 1653 Chinese junior high school students. The results show that students prioritize accepting the given information to pose mathematical problems, while few choose to change the given information. Most students used chaining, and very few students used symmetry to pose mathematical problems. From a developmental perspective, excluding the number of problems, there were grade differences in the selectivity of MPP strategies among students in grades 7, 8, and 9. Still, for each grade, accepting the given information and chaining were the most used strategies in the category therein. More than 77.56% (1282 students) chose category B to pose further mathematical problems after accepting or changing the given information to pose mathematical problems. The results of path analysis illustrate that there are two main routes of the evolution of the selections of the strategies of MPP of junior high school students: the first one is from category A to category B, and the second one is after the students use changing the given information, they are present with the selection of strategies, either use symmetry or chaining. The results may have important implications for the teaching and learning of problem-posing.

Published: May 2024

AbstractThis research tackles the challenges Ph.D. students face in academic publishing, which are not fully addressed by existing support systems. It introduces the personal learning environment-based writing for publication (PLE-WfP) platform, created to offer extensive support in academic writing and publication. Developed and tested over ten months with thirteen Year 1 Ph.D. Chinese students at a Thai university, the platform uses a mixed-methods approach encompassing development, intervention, and feedback analysis through reflective diaries. The PLE-WfP platform, structured in individual, group, and submission stages, guides students from beginning writing to collaborative research and final publication, addressing common publishing challenges. Participants expressed a strong preference for the platform’s personalized assistance over conventional methods, highlighting its relevance, adaptability, promptness, and thoroughness. The importance of the academic community in enhancing collaborative writing, confidence, emotional regulation, and resource sharing was also emphasized. This study highlights the need for emotional and financial support in addition to cognitive and technical assistance in academic writing. By providing a novel scaffolding approach, this research contributes valuable insights and solutions to the academic community, demonstrating significant theoretical and practical benefits for global academic discourse.
Turkish women’s perception of low sexual desire, its causes and consequences: an online qualitative survey
Authors: Tetik Sinan , Yalçınkaya Alkar Özden 
Published: May 2024

Background The nature of sexual desire is complex, and little phenomenological consensus exists about its meaning. Low sexual desire (LSD) is a commonly reported sexual difficulty among women, but it is less frequently associated with sexual distress. The aim of this qualitative study is to explore women’s understanding of sexual desire, and their perceptions of factors that may contribute to LSD, its effects and their methods of seeking help. Methods The research employed a questionnaire with 12 open-ended questions, developed by the researchers based on sexual script theory. Data were collected from 165 heterosexual Turkish women who reported LSD, recruited through social media platforms between August and October 2021. The data were analysed using a contextual form of thematic analysis to identify and explore patterns. Results The ages of the participants ranged from 20 to 63 years. The majority of participants held a Bachelor’s degree (81.2%) and in a relationship (78.8%). Three main themes emerged from the study: (1) gendered messages concerning sex, (2) multi-level sexual desire, and (3) minimisation. The research revealed that women’s sexual desire is often ignored and repressed, and has negative consequences if not expressed in socially acceptable contexts. The causes of LSD in women go beyond personal factors, and include relational and social influences. Women experiencing LSD report distressing effects on their relationships and general wellbeing, yet they tend not to seek help. Conclusions Our findings contribute to a deeper understanding of the factors impacting women’s sexual desire and the barriers to seeking help.
University students’ use of language learning strategies in English-medium instruction classes
Authors: Garner Joe 
Published: May 2024

Abstract
The last twenty years have seen dramatic growth in the provision of English-medium instruction (EMI) courses at
universities. On such courses, many students learn academic content through a language other than their first language (L1). This
often poses significant language-related challenges to students which can impede content learning. To cope with the linguistic
challenges, students sometimes employ language learning strategies (LLS). However, despite the rapid growth in the provision of
EMI, little research has been conducted into LLS use in an EMI context. This systematized review examines 36 relevant studies. The
findings show that over time EMI students modify their strategic behavior as they become more aware of the strategies which meet
their learning needs. Furthermore, learners gradually use more content-related strategies as they progress through their EMI
courses. Although strategy deployment is generally self-directed, the findings indicate that LLS instruction can benefit learners.
Therefore, it is recommended that EMI courses be supported by embedded EAP courses which provide strategy instruction alongside
the teaching of discipline-specific vocabulary and discourse practices. The review also raises questions about the role of
students’ L1 in EMI. By shedding light on existing studies in the field, the review highlights opportunities for future
research.
Asymmetry in temporal specification between affirmation and negation
Authors: Miestamo Matti , Silvennoinen Olli O. , Yurayong Chingduang 
Published: May 2024

Abstract
One cross-linguistically recurrent asymmetry between affirmation and negation is the neutralization of
tense-aspect distinctions in negatives. A functional explanation proposed for this is that in their typical discourse context
negatives have less need for temporal specification than affirmatives and in some languages this discourse preference is reflected
as fewer tense-aspect distinctions in grammar. To examine whether such a discourse preference exists, we compare the use of
temporal adverbials in affirmatives and negatives in English, Finnish and Korean corpus data. The results provide qualified
support for the hypothesized discourse preference: in English and Korean, affirmatives are likelier to have temporal adverbials
than negatives, but Finnish shows no statistically significant difference. In English and Finnish, affirmatives are likelier than
negatives to contain adjuncts indicating temporal position. Verb semantics is found to interact with temporal specifications. The
study also uncovers further differences between affirmatives and negatives in the use of adverbials.
Exploring the role of service dogs for Canadian military Veterans experiencing suicidality
Authors: Pavelich Alexandria R. , Dell Colleen A. , De Groot Paul 
Published: May 2024

Abstract
Despite ample anecdotal evidence, there are limited meaningful studies speaking to the important role of the human-animal bond (HAB) in reducing suicidality. However, research is increasingly showing the viability of service dogs (SDs) as a complementary approach for military Veterans suffering from post-traumatic stress disorder (PTSD) and substance use harms – two of the strongest indicators of suicidality across any population. An original, exploratory study completed in 2020 focused on how SDs supported Canadian Veterans living with PTSD and substance use concerns. From this work, a secondary analysis was then undertaken: 28 transcripts were examined through thematic analysis to explore the experiences of the Veterans who were identified as being at high risk for suicide to better understand how SDs may assist with their suicidality. Our methodological approach for the secondary analysis employed affective coding to discover how the social support system enabled by the SDs reduced experiences of loneliness and hopelessness, as well as symptoms of PTSD, depression, and substance use concerns that are commonly associated with suicidality. The SDs were reported by the Veterans as being a catalyst in reducing self-harm and suicidality, as the HAB provided a unique and necessary form of social support for Veterans that was distinct from what other human-human interactions could provide. While acknowledgement of how context specificity and the lived experience of each individual remains crucial for making sense of suicidality, the significant finding from this research has been the identification of the critical impact that SDs have in the lives of Veterans when it comes to preventing suicide. The SD has been explained as a bridge to improve Veterans’ overall quality of life and reduce markers commonly recognized as precursors to suicide – a finding that may be critical in helping reduce future suicide risk among military Veterans, and warrants further investigation.
Catalyst-free MBE growth of PbSnTe nanowires with tunable aspect ratio
Authors: Mientjes Mathijs G C , Guan Xin , Lueb Pim J H , Verheijen Marcel A , Bakkers Erik P A M 
Published: May 2024

Abstract
Topological crystalline insulators (TCIs) are interesting for their topological surface states, which hold great promise for scattering-free transport channels and fault-tolerant quantum computing. A promising TCI is SnTe. However, Sn-vacancies form in SnTe, causing a high hole density, hindering topological transport from the surface being measured. This issue could be relieved by using nanowires with a high surface-to-volume ratio. Furthermore, SnTe can be alloyed with Pb reducing the Sn-vacancies while maintaining its topological phase. Here we present the catalyst-free growth of monocrystalline PbSnTe in molecular beam epitaxy. By the addition of a pre-deposition stage before the growth, we have control over the nucleation phase and thereby increase the nanowire yield. This facilitates tuning the nanowire aspect ratio by a factor of four by varying the growth parameters. These results allow us to grow specific morphologies for future transport experiments to probe the topological surface states in a Pb1–x

Published: May 2024

Abstract
The interconnection bottleneck caused by limitations of cable number, inner space and cooling power of dilution refrigerators has been an outstanding challenge for building scalable superconducting quantum computers with the increasing number of qubits in quantum processors. To surmount such an obstacle, it is desirable to integrate qubits with quantum–classical interface (QCI) circuits based on rapid single flux quantum (RSFQ) circuits. In this work, a digital flux tuner for qubits (DFTQ) is proposed for manipulating flux of qubits as a crucial part of the interface circuit. A schematic diagram of the DFTQ is presented, consisting of a coarse tuning unit and a fine-tuning unit for providing magnetic flux with different precision to qubits. The method of using DFTQ to provide flux for gate operations is discussed from the optimization of circuit design and input signal. To verify the effectiveness of the method, simulations of a single DFTQ and quantum gates including a Z gate and an iSWAP gate with DFTQs are performed for flux-tunable transmons. The quantum process tomography corresponding to the two gates is also carried out to analyze the sources of gate error. The results of tomography show that the gate fidelities independent of the initial states of the Z gate and the iSWAP gate are 99.935% and 99.676%, respectively. With DFTQs inside, the QCI would be a powerful tool for building large-scale quantum computers.

Abstract
As a non-destructive testing technology, neutron imaging plays an important role in various fields, including material science, nuclear engineering, and fundamental science. An imaging detector with a neutron-sensitive image intensifier has been developed and demonstrated to achieve good spatial resolution and timing resolution. However, the influence of the working voltage on the performance of the neutron-sensitive imaging intensifier has not been studied. To optimize the performance of the neutron-sensitive image intensifier at different voltages, experiments have been performed at the China Spallation Neutron Source (CSNS) neutron beamline. The change in the light yield and imaging quality with different voltages has been acquired. It is shown that the image quality benefits from the high gain of the microchannel plate (MCP) and the high accelerating electric field between the MCP and the screen. Increasing the accelerating electric field is more effective than increasing the gain of MCPs for the improvement of the imaging quality. Increasing the total gain of the MCP stack can be realized more effectively by improving the gain of the standard MCP than that of the nMCP. These results offer a development direction for image intensifiers in the future.
V0405 Dra: A New Deep and Low Mass Ratio Contact Binary with Extremely Fast Decrease in the Orbital Period

Published: May 2024

Abstract
V0405 Dra is a W UMa-type binary star. Based on the TESS data, we have conducted an orbital period study and performed a light curve analysis for the system. The orbital period study reveals that the O − C curve for V0405 Dra exhibits secular decrease at an extremely high rate of dP/dt = −2.71 × 10−6 day year−1, along with periodic variations characterized by an amplitude of A
3 = 0.0032 day and a period of P
3 = 1.413 years. The orbital periodic change is possibly due to the light-travel time effect resulting from an additional third body in the system, for which we estimate a minimum mass of M
3 = 0.77M
⊙. By employing the 2013 version of the Wilson-Devinney (W-D) method to synthesize a light curve, we derived photometric solutions indicating that V0405 Dra is a new deep (f = 68.7%) and low-mass ratio (q = 0.175) contact binary. The fast decrease in its orbital period is likely caused by mass transfer from the more massive primary star to the less massive secondary star, or due to angular momentum loss. With further mass transfer and loss of angular momentum, the binary will gradually evolve into a tighter contact configuration, eventually leading to a merger into a single star, following the evolutionary paths suggested for such deep and low mass ratio contact binaries.

Abstract
The response of floating wind turbines (FWT) are susceptible to stochastic wave variations. For the optimal operation of FWT, a comprehensive understanding of the phaseresolved wave dynamics and the consequential system response is crucial for real-time monitoring and control. A multi-variate, multi-step, long short term memory (MLSTM), a type of recurrent neural network (RNN) is used to capture complex system dynamics for real-time application. Results indicate that the integration of a wave prediction-reconstruction (WRP) model substantially enhances prediction accuracy by 50% on average relative to the baseline model. The improvement is consistent across various wave extremity and prediction horizons, thereby significantly broadening the scope for timely and precise predictive capabilities.

Published: May 2024

Abstract
Two advanced X-band radars have been developed and deployed by Texas Tech University to provide continuous wind measurements serving project AWAKEN, including the construction of near real-time dual-Doppler synthesized wind fields covering a large 35 km x 35 km analysis domain. This deployment represents the first overland long duration utilization of the technology, which was configured to document a wide range of wind energy relevant flows spanning turbine inflow/wake flow to regional wind flows and wind plant interactions. The overland environment coupled with technology innovation has led to very high data availability yielding a growing archive of measurements documenting diverse atmospheric phenomena including numerous instances of wind plant interaction. Through the first few project months, data availability greater than 90%, 80% and 70% has been assessed at the ranges of 8 km, 16 km, and 25 km, respectively. Robust data availability coupled with fast radar scan speeds and high along beam measurement resolution position advanced Doppler radar technology to broadly contribute to diverse wind energy measurement applications covering domains sizes that far exceed existing industry standard measurement systems.

Authors: Diallo M , Letang L , Totel B , Poncet P , Andri P P Y 
Published: May 2024

Abstract
This study presents a novel method for improving wind power ramp events forecasts up to six hours ahead by utilizing data assimilation of SCADA measurements with an ensemble of Weather Research and Forecasting (WRF) models estimates. Leveraging data from nine wind farms in France and Belgium, the approach aims to improve WRF model predictions for wind speed and ramp event timing. The methodology employs grid and observational nudging techniques, enhancing model accuracy by incorporating real-time observational data. Key findings demonstrate that nudging significantly reduces Mean Absolute Error (MAE), decreases the Time Distortion Index (TDI), and increases the Probability of Detection (POD) of ramp events. Nudged ensemble members outperform non-nudged counterparts, exhibiting better accuracy in identifying true ramp events and reducing false alarms. MAE, TDI and POD improvements are as high as 3.7%, 8.5% and 37%, respectively. The study also explores the benefits of an ensemble approach, highlighting improved accuracy in predicting ramp rate magnitudes and providing valuable insights for grid stability management. This research contributes to wind power forecasting, showcasing the importance of integrating SCADA data into predictive models.
