Published: June 2024

AbstractGroup transfer polymerization (GTP) plays a crucial role in polymerizing (methyl) acrylate. The utilization of cheap and easily synthesized thiourea anion (TUA) combined with pinacolborane (HBpin) undergoes controlled GTPs of methyl methacrylate (MMA), methacrylate (MA), and α‐methylenebutyrolactone (MBL) at ambient temperature. The mechanistic study reveals that the TUA′‐1 having ‐NEt2 moiety works out as a cocatalyst to assist HBpin undergoes the 1,4‐hydroboration reaction with α, β‐unsaturated acrylates to in situ generate a boron enolate (boryl ketene acetal [BKA]). Different from typical GTP, in which silyl ketene acetal (SKA) is used as an initiator, this work shows that BKA could act as an initiator with the assistance of the cocatalyst TUA′‐1 to generate the polymer. The chain end groups of the obtained polymer are characterized by MALDI‐TOF‐MS, indicating one of the chain ends features a hydride from the HBpin and another chain end has a linear or back‐biting cyclic structure. Moreover, the polymerization process is strongly supported by density functional theory (DFT) calculations. The application of BKA expands the research area of GTP reactions. The tunable and structural properties of TUA/hydroboranes significantly broaden the types of initiators in the GTP and pave a new methodology to achieve functional polymers.

AbstractPulmonary hypertension (PH) adds a substantial disease burden, including higher mortality, when associated with interstitial lung disease (ILD), a severe, chronic, progressive condition. Yet little is known of the lived experiences, perspectives, priorities, and viewpoints of patients and carers living with PH‐ILD. The Voice of the Patient meeting at the center of this qualitative research study aims to provide these difficult‐to‐obtain insights from a European perspective for the first time. The multistakeholder approach brought together four PH‐ILD patients, three primary caregivers, two patient associations, clinical experts, sponsor representatives, and a facilitator. Of the six major themes identified in the thematic analysis, symptoms, and physical limitations were the most impactful. Shortness of breath was the most bothersome symptom affecting patients daily. Further symptoms included fatigue, cough, dizziness, syncope, edema, and palpitations. Physical limitations focused on reduced mobility, impacting patients’ ability to perform daily tasks, hobbies, sports, and to enjoy travel. Existing antifibrotic and pulmonary arterial hypertension‐targeted treatments were perceived as beneficial. However, despite advances in treatment, severe disease burdens and high unmet medical needs persist from the perspectives of patients. Most meaningful to patients’ daily wellbeing was supplemental oxygen, enabling greater mobility. Patients and carers reported difficulties and barriers in navigating the healthcare system and obtaining adequate information to reduce their considerable uncertainties, documenting the substantial challenges that rare and complex conditions such as PH‐ILD pose for routine clinical practice beyond PH expert centers and indicating an urgent need for high‐quality patient‐ and clinician‐directed information to support patient‐centered care.

Published: June 2024

AbstractBackgroundA history of intimate partner violence (IPV) and/or sexual violence may impact a patient's birth experience. Limited information is available on the potential for re‐traumatisation through routine obstetrical practices and the effect on mode of delivery.ObjectivesTo identify whether there is a difference in mode of delivery between obstetrics patients who have experienced IPV/sexual violence compared to those who have not.Search StrategyMEDLINE and EMBASE were searched through inception to February 2024 for terms related to obstetric mode of delivery, IPV and sexual abuse.Selection CriteriaPeer‐reviewed, retrospective and prospective studies that contained original data.Data Collection and AnalysisTwo authors independently conducted data extraction. A random‐effects meta‐analysis was used to pool outcomes. Cochrane's chi‐squared test and the I2 statistic was used to examine the statistical heterogeneity of pooled effect estimates. All studies were evaluated using the risk of bias in a non‐randomised study‐I tool.Main ResultsThirty studies (n = 280 864) were eligible for inclusion. The likelihood of caesarean delivery was significantly higher in those who had experienced IPV/sexual violence compared to those who had not: OR = 1.16, CI = 1.05–1.27; I2 = 71. Pooled analysis of reported operative delivery rates did not reveal any significant increase in operative delivery rate for those who had experienced IPV/sexual violence versus those who had not: OR = 1.14, 95% CI = 0.89–1.45, I2 = 77%. Risk of bias for the included studies were moderate to serious.ConclusionsObstetrics patients with a history of IPV/sexual violence appear to be more likely to deliver via caesarean section as compared to those who do not.
Evaluation of the fixed‐point iteration of minimizing delta debugging
Authors: Vince Dániel , Kiss Ákos 
Published: June 2024

AbstractThe minimizing Delta Debugging (DDMIN) was among the first algorithms designed to automate the task of reducing test cases. Its popularity is based on the characteristics that it works on any kind of input, without knowledge about the input structure. Several studies proved that smaller outputs can be produced faster with more advanced techniques (e.g., building a tree representation of the input and reducing that data structure); however, if the structure is unknown or changing frequently, maintaining the descriptors might not be resource‐efficient. Therefore, in this paper, we focus on the evaluation of the novel fixed‐point iteration of minimizing Delta Debugging (DDMIN*) on publicly available test suites related to software engineering. Our experiments show that DDMIN* can help reduce inputs further by 48.08% on average compared to DDMIN (using lines as the units of the reduction). Although the effectiveness of the algorithm improved, it comes with the cost of additional testing steps. This study shows how the characteristics of the input affect the results and when it pays off using DDMIN*.

The magnetized flow of Newtonian/non‐Newtonian fluid across a curved surface with reaction kinetics and non‐Fourier heat transfer
Authors: Khan Muhammad Riaz , Mao Shipeng 
Published: June 2024

AbstractThis study aims to compare the dual solutions of the problem describing the magnetized motion of a Newtonian and second‐grade fluid induced by a curved stretching/shrinking surface using the associations of homogeneous–heterogeneous reaction and Cattaneo–Christov model. The model is further developed using the properties of convective heat transfer, suction velocity, Joule heating, heat source/sink, and viscous dissipation with the porous medium. The relevant transformations are applied to the governing partial differential equations (PDEs) resulting in the system of nonlinear ordinary differential equations (ODEs). The solution technique makes use of the computational scheme in MATLAB known as the bvp4c technique. All relevant findings are obtained using a wide range of dimensionless parameters. The Cattaneo–Christov model and the second‐grade fluid transmits heat faster than the classical Fourier law and Newtonian fluid as well as the heat transfer rate of both fluids was found to drop as the values of Eckert number and curvature parameter enhances. Moreover, the Newtonian fluid has lower friction drag than the second‐grade fluid and the concentration of the bulk fluid is declined by the rising values of hetrogeneous and homogeneous reaction parameter. With potential applications in a variety of engineering fields, including thermal management systems and nanofluid‐based technologies, this work is significant for understanding MHD flow of second‐grade nanofluids over curved surfaces, incorporating heterogeneous reactions and the Cattaneo–Christov model. The results also aid in improving heat transfer efficiency and understanding of fluid behavior under various parameter situations, providing information for improving industrial processes and advanced materials engineering design considerations.

Published: June 2024

AbstractOne Gram-negative, rod-shaped bacterial strain, isolated from an undescribed Heterorhabditis entomopathogenic nematode species was characterized to determine its taxonomic position. The 16S rRNA gene sequences indicate that it belongs to the class Gammaproteobacteria, to the family Morganellaceae, to the genus Photorhabdus, and likely represents a novel bacterial species. This strain, designated here as CRI-LCT, was therefore molecularly, biochemically, and morphologically characterized to describe the novel bacterial species. Phylogenetic reconstructions using 16S rRNA gene sequences show that CRI-LCT is closely related to P. laumondii subsp. laumondii TT01T and to P. laumondii subsp. clarkei BOJ-47T. The 16rRNA gene sequences between CRI-LCT and P. laumondii subsp. laumondii TT01T are 99.1% identical, and between CRI-LCT and P. laumondii subsp. clarkei BOJ-47T are 99.2% identical. Phylogenetic reconstructions using whole genome sequences show that CRI-LCT is closely related to P. laumondii subsp. laumondii TT01T and to P. laumondii subsp. clarkei BOJ-47T. Moreover, digital DNA-DNA hybridization (dDDH) values between CRI-LCT and its two relative species P. laumondii subsp. laumondii TT01T and P. laumondii subsp. clarkei BOJ-47T are 65% and 63%, respectively. In addition, we observed that average nucleotide identity (ANI) values between CRI-LCT and its two relative species P. laumondii subsp. laumondii TT01T and P. laumondii subsp. clarkei BOJ-47T are 95.8% and 95.5%, respectively. These values are below the 70% dDDH and the 95–96% ANI divergence thresholds that delimits prokaryotic species. Based on these genomic divergence values, and the phylogenomic separation, we conclude that CRI-LCT represents a novel bacterial species, for which we propose the name Photorhabdus africana sp. nov. with CRI-LCT (= CCM 9390T = CCOS 2112T) as the type strain. The following biochemical tests allow to differentiate P. africana sp. nov. CRI-LCT from other species of the genus, including its more closely related taxa: β-Galactosidase, citrate utilization, urease and tryptophan deaminase activities, indole and acetoin production, and glucose and inositol oxidation. Our study contributes to a better understanding of the taxonomy and biodiversity of this important bacterial group with great biotechnological and agricultural potential.
Designing Intelligent Rock Support Systems to Detect Gravity-Driven Wedges
Authors: Varelija Michel , Hartlieb Philipp 
Published: June 2024

AbstractIntelligent rock bolts can be used in mining operations to acquire information on the bolt's status and movements of the rock mass. The future value of this technology resides in optimizing the support layout and increasing safety. The primary goal of this research is to investigate the sensor spatial distribution necessary for efficiently identifying roof wedges in mines. Roof wedges occur when three joints intersect over the roof, forming a triangular shape. They present a hazard by falling and causing damage. Sensor density refers to the number of sensors on a single rock bolt and the number of intelligent rock bolts in the mine or one section. Too many sensors drive costs up, and too few sensors compromise measurement quality. This research visualizes and investigates the results of the simulated models of intelligent rock bolts depending on the number of installed sensors and intelligent bolts to get a better understanding of the problem and describe the technique used, including numerical simulations and the considered parameters. Furthermore, it offers insight into the findings' possible implications, providing knowledge about the viability of using intelligent rock bolts.

Published: June 2024

Abstract
Hospital records are used to identify suicide attempts in many countries but not all individuals present to hospital after a suicide attempt i.e., suggesting a ‘hidden number’. Our aim was to present the prevalence of suicide ideation, plans, attempts, and suicides among Danish adolescents, including attempts not resulting in hospital contact. The study population consisted of participants in the Danish National Birth Cohort participating in an 18-year follow-up, with individual-level linkage to national register data. Prevalence was estimated with a variable with mutually exclusive categories ranging from no suicidality to self-reported suicide ideation, -plans, -attempt and hospital-recorded suicide attempt and stratified on sex and parental income. The ‘hidden number’ was estimated as the ratio between suicide attempts with and without hospital contact. Among 47 858 participants, all aged 18-years, 36% girls and 28% boys reported suicide ideation at least once in their life. In addition, 6% girls and 3% boys had either reported or been recorded with a suicide attempt. For every attempt recorded in the hospital setting, two girls (ratio, 1:2) and six boys (ratio, 1:6) reported having attempted suicide without hospital contact. The prevalence of any suicide attempt was 8% and 3% in the lowest and highest income group, respectively. Before age 18, 0·011% girls and 0·016% boys had died by suicide. In conclusion, suicidal ideation and behaviour are common in adolescents and there is a substantial ‘hidden number’ of adolescents with suicide attempt. These results emphasize the need for early age suicide preventive interventions in community-settings e.g., school environments.
Competitive coupon promotions: a theory-based model for online retail platforms and third-party sellers
Authors: Li Zonghuo , Popkowski Leszczyc Peter T. L. 
Published: June 2024

AbstractIn the realm of online retail, third-party sellers (TPSs) are progressively being permitted to offer their products on various platforms, often in exchange for a commission fee. This dynamic creates a natural competitive environment between the platforms and the TPSs. An increasingly prevalent strategy to enhance product competitiveness is the utilization of coupon promotions, which both platforms and TPSs have adopted. This study developed a theoretical model to study the dynamics of a retail system wherein an online platform facilitates the sale of products by a TPS, while simultaneously introducing products of differing quality levels. Four distinct promotion scenarios, based on whether the platform and TPS implement coupon offerings, are examined. The analysis outcomes reveal that coupon promotions initiated by both the platform and TPS result in reduced actual payments from consumers, particularly when the platform’s product holds a quality advantage. Surprisingly, in cases where the TPS’s product boasts a quality advantage, consumer actual payments may be higher in a promotion scenario compared to a non-promotional one. Furthermore, we demonstrate that the platform can leverage the TPS’s promotion efforts, particularly when commission fees and incremental purchases are on the higher side. Intriguingly, in situations where the TPS’s product holds a quality advantage, a co-promotion strategy, as opposed to a sole TPS-promotion approach, emerges as the optimal choice, especially when commission fees are substantial and incremental purchases are limited.
Genetic analysis of yield and fiber quality traits in cotton (Gossypium hirsutum L.) under full and deficit irrigation conditions using full diallel method
Authors: Gören Hatice Kübra , Canavar Öner 
Published: June 2024

AbstractThe aim of the study was to assess the genetic structure and quantitative heritability of cotton yield, yield components and fiber quality parameters under well-watered (100%) and deficit (50%) irrigation conditions using a complete full diallel cross method with six cotton genotypes. The F1 and F2 generations were obtained to study the effect of irrigation conditions on genotypic variation and maternal effects on the traits studied. Parental, F1 and F2 generations were growed under full and deficit irrigation conditions and selected agronomic and fiber quality traits were measured. The data were analysed using various methods, including Griffing Method I, Model I analysis of variance, full diallel table analysis of variance, Jinks-Hayman diallel hybrid analysis. The Jinks-Hayman analysis of variance showed that dominant effects were more important in the inheritance of all traits, as indicated by the negative value of the difference between the additive variance and the dominance variance (D-H1). In addition, the average degree of dominance (H1/D)1/2 was greater than 1, indicating the predominance of dominant gene action in inheritance. The study concluded that starting selection in the F5–F6 generation is appropriate for drought resistant cotton breeding studies. It also emphasised the importance of conducting drought resistant cotton breeding under drought conditions due to the differences in gene movement between well-watered irrigation and drought stress conditions. The study highlighted the importance of population selection, environmental factors, data collection and analysis interpretation in breeding studies. It suggested that the Griffing diallel analysis method is suitable for hybrid breeding studies, while the Jinks-Hayman type analysis method is suitable for studying the genetic structures of populations.
Is it what you say or how you say it?

AbstractThis study investigates the mechanisms driving the effectiveness of free-form communication in promoting cooperation within a sequential social dilemma game. We hypothesize that the self-constructing nature of free-form communication enhances the sincerity of messages and increases the disutility of dishonoring promises. Our experimental results demonstrate that free-form messages outperform both restricted promises and treatments where subjects select and use previously constructed free-form messages. Interestingly, we find that selected free-form messages and restricted promises achieve similar levels of cooperation. We observe that free-form messages with higher sincerity increase the likelihood of high-price and high-quality choices, thereby promoting cooperation. These messages frequently include promises and honesty, while threats do not promote cooperation. Our findings emphasize the crucial role of the self-constructed nature of free-form messages in promoting cooperation, exceeding the impact of message content compared to restricted communication protocols.
