A conceptual model of autonomous ship remote operators' competency
Authors: Kuntasa Tanan , Lirn Taih-Cherng
Published: December 2024

The Shore Control Centre (SCC) is being developed and tested as an autonomous ship vessel with remote control. However, since the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW) regulation's competency standard has yet to be altered, it must be revised and modified. Therefore, this study aims to define the competency of remote operators on an autonomous ship from ashore and develop a conceptual model of remote operators' competency. This study used both primary data by interviewing executives from four groups of maritime experts, and secondary data from academic databases, IMO, classification society and maritime companies. Academic databases are employed to conclude the academicians' view on remote operators’ (ROs’) competency and the other data sources are used to conclude the industrial view on the RO's competency. The content analysis technique was used to determine the presence of keywords or concepts from secondary data and develop a conceptual model. The study's findings present four main dimensions to indicate the development of future training and development programs for RO officers: navigation, cargo handling and stowage, controlling the ship's operation and care for persons onboard, and information technology; and present 45 competencies of ROs for managing autonomous ships from ashore, which a conceptual model can explain.
Conflicting Legal Perspectives on the Establishment of Kingdom of Serbs, Croats, and Slovenes
Authors: Ivašković Igor
Published: December 2024

The analysis delves into the complex legal intricacies surrounding the establishment of South Slavic state entities post-World War I, as international law of the time didn't fully encompass modern legal instruments defining international relations subjects. Nonetheless, legal arguments affirm the statehood of the State of SCS, formed within the former Austro-Hungarian Empire through legitimate representative bodies, despite lacking formal international recognition. The Croatian state transitioned governance under the National Council of SCS without abolishing its institutions. The analysis of the “December 1st Act” highlights procedural violations during the forming of the Kingdom of SCS, indicating a deviation from authorized scope, though it did not render the new state's government illegitimate. The negotiating process favored Serbian authorities, evident in the “Vidovdan” Constitution, yet it doesn't suffice to claim the State of SCS was annexed by the Kingdom of Serbia. Legally, there's little ambiguity, but disputes in international legal rulings and interpretations uncover internal political tensions and external pragmatic influences.

Authors: Peixoto Alberto Borges , Bravo-Valenzuela Nathalie Jeanne Magioli , Rolo Liliam Cristine , Mattar Rosiane , Moron Antonio Fernandes , Tonni Gabriele , Araujo Júnior Edward
Published: December 2024

Objective:

To evaluate the influence of pre-existing maternal diabetes mellitus on fetal myocardial performance index and systolic-to-diastolic duration ratio.

Methods:

Prospective cohort study included 179 pregnant women between 20 and 36w6d, divided into 3 groups: Group 1 (120, normal), Group 2 (31, type 1 diabetes mellitus), and Group 3 (28, type 2 diabetes mellitus). Systolic-to-diastolic duration ratio was calculated as the sum of isovolumic contraction time and ejection time divided by the sum of isovolumic relaxation time and ventricular filling time. Spectral Doppler was used to assess left ventricle systolic-to-diastolic duration ratio. Tissue Doppler was used to assess right ventricular filling time. Using spectral Doppler, left ventricle myocardial performance index was calculated as the sum of isovolumic contraction time and isovolumic relaxation time divided by ejection time.

Results:

Pre-existing maternal diabetes mellitus had a significant influence on fasting glucose levels (p < 0.001), left ventricle isovolumic contraction time (p < 0.001), left ventricle ejection time (p = 0.025), and left ventricle myocardial performance index (p < 0.001). Group 2 had higher left ventricle isovolumic contraction time (0.036 vs. 0.031 sec, p = 0.001) and left ventricle myocardial performance index (0.487 vs. 0.453, p = 0.003) compared with Group 1. Group 3 showed higher left ventricle myocardial performance index (0.492 vs. 0.449, p = 0.006) and lower left ventricle ejection time (0.161 vs. 0.169 sec, p = 0.038) than Group 1. Left ventricle systolic-to-diastolic duration (p = 0.704), right ventricle systolic-to-diastolic duration ratio’ (p = 0.757), left ventricle isovolumic contraction time (p = 0.163), left ventricle ejection time (p = 0.093), and left ventricle myocardial performance index (p = 0.087) were not useful parameters in predicting composite neonatal outcomes.

Conclusion:

Pre-existing maternal diabetes mellitus had significant influence on fetal left ventricle myocardial performance index, but no effect on systolic-to-diastolic duration ratio. Systolic-to-diastolic duration ratio was not useful in predicting adverse perinatal outcomes.

Authors: Zou Jinghui , Li Cheng , Wu Hangyu , Xue Aijiao , Yan Lulu , Zhang Yisheng
Published: December 2024

The objective of this study was to investigate the genetic link between the age at first birth (AFB) and the occurrence of preterm labor and delivery, utilizing Mendelian randomization (MR) data alongside genomewide association analysis (GWAS). We obtained AFB-related GWAS summary data from the European Bioinformatics Institute database and preterm labor and delivery data was sourced from the FinnGen Consortium. The study considered AFB as exposure variables, with the incidence of preterm labor and delivery serving as the outcome variable. Several MR analysis methods, such as inverse-variance weighted (IVW), MR Egger, weighted median, simple, and weighted mode were utilized. Besides MR-Egger intercepts, Cochrane’s Q test evaluated heterogeneity in the MR data, while MR-PRESSO test checked for horizontal pleiotropy. To assess the association’s sensitivity, A leave-one-out approach was utilized to evaluate the sensitivity of the association. The IVW analysis validated that AFB is an independent risk factor for preterm labor and delivery (p < .001). Horizontal pleiotropy was unlikely to bias causality (p > .05). The likelihood of horizontal pleiotropy affecting causality was low (p > .05), and there was no indication of heterogeneity among the genetic variants (p > .05). Ultimately, a leave-one-out analysis confirmed the stability and reliability of this correlation. Our research indicated that AFB is a protective factor for preterm labor and delivery. Further research is required to clarify the possible mechanisms.
Evaluating How Historical Climate Change Affected a Heavy Snowfall Event in Northern Japan in Mid‐December 2021 Using Two Pseudo Global Warming Methods
Authors: Tamura K. , Sato T.
Published: December 2024

In mid‐December 2021, heavy snowfall occurred when an extratropical cyclone passed around Hokkaido, northern Japan. In this study, we investigated the contribution of historical climate change to the heavy snowfall event using large ensemble simulation data sets and two pseudo global warming (PGW) methods. We classified the large ensemble simulation data sets by the pressure pattern and identified the extratropical cyclone event. Composite analyses reveal that the development of the extratropical cyclone can be attributed to historical climate change. We ran the PGW method with the classified meteorological data as the input data and found that the development of the extratropical cyclone resulted in enhanced water vapor transport and intensified local convergence in the lower troposphere, causing heavy precipitation. We also found that oceanic warming made a minimal contribution to the precipitation in this event. These findings highlight the importance of considering historical changes in event‐specific synoptic‐scale atmospheric conditions when evaluating the contributions of climate change to extreme events.
Effect of herbal toothpaste on the colour stability, surface roughness, and microhardness of aesthetic restorative materials—an in vitro study
Authors: Hazra Yashodhara , Rao Arathi , Natarajan Srikant , Srikrishna Suprabha Baranya
Published: December 2024

Objective

To evaluate the in vitro effects of two commonly used commercial herbal toothpastes (Dabur Meswak and Patanjali Dant Kanti) on the colour stability, surface texture, and microhardness of two commonly used aesthetic restorative materials, i.e., nanofilled composite and resin-modified glass ionomer cement (NFC and RMGIC).

Materials and methods

The samples were brushed twice daily using two herbal toothpastes, Dabur Meswak (Dabur India Ltd) and Patanjali Dant Kanti (Patanjali Ayurved Ltd, India) and powered toothbrush. Atomic force microscopy, spectroscopy, and digital micro hardness testing were used to estimate the changes in the surface roughness, colour change, and hardness of the samples, respectively, at baseline and after six months.

Results

Regarding colour change, a statistically significant difference (P < 0.05) was observed between baseline and six months in both the RMGIC and NFC for both herbal toothpastes. Both RMGIC and NFC had higher Ra values when brushed with either toothpaste, indicating a rough surface. The greatest increase in the mean difference in microhardness was observed for the Patanjali Dant Kanti toothpaste samples brushed on both NFC and RMGIC.

Conclusion

In our work, herbal toothpaste increased surface roughness and microhardness and caused colour changes in the two most commonly used aesthetic restorative materials.

Clinical relevance

Herbal toothpastes affect the surface texture of aesthetic dental restorative materials. Dental professionals may need to educate their patients to be cautious regarding the prolonged use of herbal toothpaste.

Published: December 2024

Preeclampsia is a common multifactorial disease of pregnancy. Dysregulation of complement activation is among emerging candidates responsible for disease pathogenesis. In a targeted exomic sequencing study of 609 women with preeclampsia and 2092 non-preeclamptic controls, we identified 14 variants within nine genes coding for components of the membrane attack complex (MAC, C5b-9) that are associated with preeclampsia. We found two rare missense variants in the C5 gene that predispose to preeclampsia (rs200674959: I1296V, OR (CI95) = 24.13 (1.25–467.43), p value = 0.01 and rs147430470: I330T, OR (CI95) = 22.75 (1.17–440.78), p value = 0.01). In addition, one predisposing rare variant and one protective rare variant were discovered in C6 (rs41271067: D396G, OR (CI95) = 2.93 (1.18–7.10), p value = 0.01 and rs114609505: T190I, 0.02 OR (CI95) = 0.47 (0.22–0.92), p value = 0.02). The results suggest that variants in the terminal complement pathway predispose to preeclampsia.

Published: December 2024

High-velocity stars and peculiar G objects orbit the central supermassive black hole (SMBH) Sagittarius A* (Sgr A*). Together, the G objects and high-velocity stars constitute the S cluster. In contrast with theoretical predictions, no binary system near Sgr A* has been identified. Here, we report the detection of a spectroscopic binary system in the S cluster with the masses of the components of 2.80  ±  0.50 M⊙ and 0.73  ±  0.14 M⊙, assuming an edge-on configuration. Based on periodic changes in the radial velocity, we find an orbital period of 372±3 days for the two components. The binary system is stable against the disruption by Sgr A* due to the semi-major axis of the secondary being 1.59±0.01 AU, which is well below its tidal disruption radius of approximately 42.4 AU. The system, known as D9, shows similarities to the G objects. We estimate an age for D9 of $$2.{7}_{-0.3}^{+1.9}\,\times \,1{0}^{6}$$

yr that is comparable to the timescale of the SMBH-induced von Zeipel-Lidov-Kozai cycle period of about 106 yr, causing the system to merge in the near future. Consequently, the population of G objects may consist of pre-merger binaries and post-merger products. The detection of D9 implies that binary systems in the S cluster have the potential to reside in the vicinity of the supermassive black hole Sgr A* for approximately 106 years.

Published: December 2024

Fibromyalgia syndrome (FMS) is a chronic disorder characterized by widespread musculoskeletal pain, fatigue and tenderness and closely associated with high levels of stress. FMS is therefore often considered a stress-related disease. A comparative study was conducted with 99 individuals diagnosed with FMS and a control group of 50 pain-free individuals. Stress indicators were classified into three categories: perceived stress assessed using the Perceived Stress Scale, and daily average salivary cortisol and hair cortisol concentrations as indicators of acute and chronic stress levels related to the hypothalamic-pituitary-adrenal axis. Analysis of variance and covariance were used to identify group differences and the influence of covariates age, sex, and body mass index. Correlational analyses further elucidated the relationship between stress indicators and clinical symptoms. Participants with FMS reported significantly higher perceived stress levels than controls (p < .001, ηp2 = 0.3), which were positively correlated with symptom burden (r = .41, p < .001). In contrast, there were no significant differences in the endocrinological stress indicators salivary and hair cortisol between the groups (p > .05), nor were these indicators associated with clinical symptoms. The study highlights the central role of perceived stress in FMS, whereas endocrinological indicators did not differentiate FMS from controls. This finding calls for a nuanced approach to clinical assessment and therapeutic interventions tailored to patients with FMS, emphasizing the management of perceived stressors.

Published: December 2024

Magnetic field effects (MFEs) in thermally activated delayed fluorescence (TADF) materials have been shown to influence the reverse intersystem crossing (RISC) and to impact on electroluminescence (EL) and conductivity. Here, we present a novel model combining Cole–Cole and Lorentzian functions to describe low and high magnetic field effects originating from hyperfine coupling, the $$\Delta$$g mechanism, and triplet processes. We applied this approach to organic light-emitting devices of third generation based on tris(4-carbazoyl-9-ylphenyl)amine (TCTA) and 2,2′,2″-(1,3,5-benzinetriyl)-tris(1-phenyl-1-H-benzimidazole) (TPBi), exhibiting blue emission, to unravel their loss mechanisms. The quality of the regression function was evaluated using k-fold cross-validation. The scoring was compared to various alternative fitting functions, which were previously proposed in literature. Density functional theory calculations, photoluminescence, and electroluminescence studies validated the formation of a TADF exciplex system. Furthermore, we propose successful encapsulation using a semi-permeable polymer, showing promising results for magnetic field sensing applications on arbitrary geometry. This study provides insights into the origin of magnetic field effects in exciplex-TADF materials, with potential applications in optoelectronic devices and sensing technologies.

Published: December 2024

A new type of position-sensitive detectors is gaining attention in the neutron community. They are scintillator based detectors that detect the scintillation light on an individual photon basis via an image intensifier and a fast image sensor. Their readout operates in event mode i.e. it produces information about individual neutron interactions, reconstructed from the sensor data, thus enabling to achieve superior spatial and temporal resolutions compared to regular detectors. Although the development of current detectors is focused on neutrons, the concept is also applicable to the detection of other particles such as high-energy photons. This document provides a description on how these detectors are built, how they operate, and what their characteristics are. An example of a detector implementation based on a Timepix3 chip is described to illustrate the detector concept. This includes a detailed description of the algorithm that reconstructs the neutron interactions from the sensor data, one of the core components that sets it apart from established scintillator-based imaging detectors. Energy-resolved epithermal neutron radiography was performed at the ISIS EMMA beamline with this detector, illustrating some of the fundamental differences in the data that can be produced with the new type of detector compared to more established types of scintillator based neutron detectors. The term LumaCam is proposed to refer to this new class of position-sensitive event-mode detectors.
Molecular mechanism of condensin I activation by KIF4A
Authors: Cutts Erin E , Tetiker Damla , Kim Eugene , Aragon Luis
Published: December 2024

During mitosis, the condensin I and II complexes compact chromatin into chromosomes. Loss of the chromokinesin, KIF4A, results in reduced condensin I association with chromosomes, but the molecular mechanism behind this phenotype is unknown. In this study, we reveal that KIF4A binds directly to the human condensin I HAWK subunit, NCAPG, via a conserved disordered short linear motif (SLiM) located in its C-terminal tail. KIF4A competes for NCAPG binding to an overlapping site with SLiMs at the N-terminus of NCAPH and the C-terminus of NCAPD2, which mediate two auto-inhibitory interactions within condensin I. Consistently, the KIF4A SLiM peptide alone is sufficient to stimulate ATPase and DNA loop extrusion activities of condensin I. We identify similar SLiMs in the known yeast condensin interactors, Sgo1 and Lrs4, which bind yeast condensin subunit, Ycg1, the equivalent HAWK to NCAPG. Our findings, together with previous work on condensin II and cohesin, demonstrate that SLiM binding to the NCAPG-equivalent HAWK subunit is a conserved mechanism of regulation in SMC complexes.
