Published: April 2024

Abstract
There is a popular use and demand of plastic products worldwide. Therefore, their quality and production rate ought to be high. Injection molding has gained populace in the manufacture of plastics because it is economical, repeatable and can manufacture complex shaped products. However, straight cooling channels characterize most injection mold tools which leads to slow and non-uniform cooling consequently resulting in low production rate and defective products. This study deals with optimization of circular cross-section conformal cooling channel design. Design of experiments is based on Taguchi method with the variable design factors being diameter, depth and pitch. Solidworks is used for 3D design, numerical simulation is conducted using Solidworks Plastics and grey relational analysis is used for multi-response optimization. Grey relational grade results showed that the optimal design was characterized by a minimum diameter (D), depth and pitch of 8 mm, 1.5 D and 2 D respectively. Analysis of variance (ANOVA) findings depicted the diameter as the only and most significant factor that contributed to all the responses concurrently. The performance of all CCC designs were superior to that of SCC. Overall, Grey relational analysis sufficed multi-response optimization in injection molding process through CCC design. The methodology adopted can be used to optimize the designs of injection mold tool components for efficiency in the production process.

Abstract
To enhance the level of refined load decomposition of the power system and make full use of seasonal change information to improve the prediction performance further, this paper proposes a seasonal short-term load combination prediction model of the power system based on modal decomposition and feature fusion multi-algorithm hybrid neural network model, i.e., the characteristics of load components are analysed for different seasons, and the corresponding models are established respectively. Firstly, The ICEEMDAN (Improved complete ensemble EMD) method decomposes the four-season load, and a new sequence is obtained based on the RCMFE (refined composite multiscale fuzzy entropy) reconstruction of each decomposition component. Secondly, the correlation between different decomposition components and different features is measured using the mRMR (Max-Relevance and Min-Redundancy) method to filter out the subset of features with high correlation and low redundancy. Finally, the BiLSTM (Bi-directional Long Short-Term Memory) model based on the Bayesian optimisation algorithm is used to predict different components of different seasonal loads separately, and the predicted values are accumulated to obtain the final results. According to the experimental findings, the proposed method can successfully balance the issues of prediction accuracy and prediction time while having a higher level of prediction accuracy than the current prediction methods. It is confirmed that the proposed method can effectively address the load power variation brought on by seasonal differences in different regions.

Abstract

Intelligent scene design schemes have become increasingly important with the development of digital media art and Augmented Reality (AR) technology. At present, the design of this scene is mostly used in urban planning. The development of AR technology makes the constructed scene more realistic and immersive while drawing virtual cities. This paper establishes a virtual city through intelligent scene and AR technology and conducts reasonable urban planning based on the collection of sunshine information. Firstly, the application of blockchain technology is introduced. Secondly, it describes the digital media art intelligent scene and AR technology. Finally, the sunshine information obtained from the intelligent scene is used to optimize the virtual city buildings. The experimental results show that: building groups based on the sunshine information identified by intelligent scene can increase the sunshine time of both residential and commercial building groups and reduce the optimization time, which greatly improves the building planning level of virtual cities. Additionally, the introduction of AR technology makes the virtual city more realistic. Therefore, this study has certain reference significance for planning virtual cities.

Published: April 2024

Abstract
Bisphenol S (BPS) is considered an emerging concern as an alternative to bisphenol A. In this study, the degradation of BPS by PS, UV, and UV/PS was comprehensively examined in fresh and saline waters. UV/PS can effectively degrade BPS, and the observed first-order rate constant, kobs, increased from 0.021 to 0.382 s− 1 with increasing PS concentration from 100 to 1000 mΜ. The addition of humic acid (HA) would inhibit the degradation of BPS, and 1/kobs was directly proportional to the concentration of HA. Eighteen degradation products, including β-scission, sulfate addition, quinone type, ring-opening, cross-coupling, were identified using high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Two possible pathways were proposed: (i) the initial step was considered to be an electron-transfer reaction from BPS to SO4•−, leading to the formation of a phenyl radical cation R1, and then phenol radical R4, 4-hydroxybenzenesulfonate cation R5, phenoxyl radical R3, resonant-type carbon-centered radical R2, and their secondary products; (ii) another pathway was the sulfate addition and hydroxylation. These primary reaction sites were further verified by theoretical calculation. This study highlights the effectiveness of UV/PS as a promising strategy for the remediation of BPS and other endocrine-disrupting chemicals in fresh and saline waters.
Abnormal analysis of wheel hub of a straddle monorail vehicle
Authors: Zengchuang Zhao , Pingbo Wu , Lihui Ren 
Published: April 2024

Abstract
This article is based on the tire six component force test and wheel hub fatigue test of a certain type of straddle monorail vehicle, and analyzes the reasons for the abnormal phenomenon of the vehicle's wheel hub. Firstly, the vehicle connecting rod was calibrated in the laboratory to obtain the "force strain" coefficient of the connecting rod under tension and compression conditions. The accuracy of this calibration was verified by comparing it with the experimental results; Subsequently, the dynamic displacement of the vehicle and the strain of the connecting rod were obtained by installing displacement sensors at different positions, and the six component force data of the tire was obtained; Finally, based on the IIW standard, the fatigue strength of the wheel hub under AW0 and AW3 operating conditions was evaluated, and the dynamic stress of the wheel hub during emergency braking, the dominant frequency of the dynamic stress of the wheel hub, and the influence of polygonal wear on the dynamic stress of the wheel hub were analyzed. The results show that the maximum dynamic loads of the vertical force of the running wheel, the lateral force of the guide wheel, and the lateral force of the stabilizing wheel are all within the limit load range, and there is a certain safety margin to ensure safe operation; Under the IIW standard, there are 1 point and 3 points on the wheel hub under AW0 and AW3 working conditions that do not meet the fatigue strength criterion requirements, and there are no abnormalities in the other indicators; During emergency braking, there was no abnormal change in the dynamic stress of the wheel hub, and the polygonal wear of the tire shoulder had little effect on the dynamic stress of the wheel hub. This explains the abnormal phenomenon of the vehicle's wheel hub and provides an important reference for subsequent wheel hub design.

Abstract
To investigate the relationship between the maternal nutritional status of multiple amino acids and vitamins during early pregnancy and the risk of preterm birth, the plasma samples of 7952 pregnant women during the 12~24 gestational weeks were enrolled, and the levels of 20 amino acids and 10 vitamins were measured. The abundance differences of representative nutrients among stratified groups of pregnant women and the potential risk of preterm birth were analyzed and evaluated. The plasma levels of aspartate, methionine, and retinol were significantly higher, and that of 4-pyridoxic acid was significantly lower in the group of preterm birth pregnancy compared to the group of full-term birth pregnancy. The odds ratios of higher levels of methionine and 4-pyridoxic acid (as compared to respective normal levels) were 2.189 (95%CI: 1.247～3.845) and 0.243 (95%CI: 0.059～0.998) in the comparison group of severe preterm birth to full-term birth pregnancy, and that of higher level of retinol (as compared to normal level) was 1.595 (95%CI: 1.162～2.190) in the comparison group of mild preterm birth to full-term birth pregnancy. It was concluded that higher levels of maternal plasma methionine and vitamin A and lower levels of vitamin B6 during early pregnancy might be significantly independent risk factors for preterm birth.

Published: April 2024

Abstract
This study aimed to elucidate the role of microRNA miR-92a-3p in the pathogenesis of adenomyosis. We focused on understanding how miR-92a-3p in exosomes derived from ectopic lesions influences the behavior of endometrial cells, DRG neurons, and Human Umbilical Vein Endothelial Cells (HUVECs), and its potential as a non-invasive diagnostic biomarker. Our findings revealed that MiR-92a-3p is significantly upregulated in exosomes derived from ectopic lesions of adenomyosis. This upregulation was associated with enhanced migration and invasion capabilities in eutopic endometrial cells, DRG neurons, and HUVECs. Furthermore, the study demonstrated a significant correlation between the levels of MiR-92a-3p in urinary exosomes and the clinical symptoms of adenomyosis, suggesting its potential as a non-invasive biomarker for the disease. This study elucidates an exosomal signaling process via miR-92a-3p that drives pathological infiltration and angiogenesis to promote adenomyosis progression. Upregulated miR-92a-3p in biofluid exosomes shows promising non-invasive biomarker potential for diagnosis and monitoring of this disease. Our findings unveil novel targets and tools for improved clinical management.Our research uncovers the significant role of miR-92a-3p in adenomyosis pathogenesis. We demonstrate that miR-92a-3p, upregulated in exosomes from ectopic lesions, enhances migration and invasion of endometrial cells, DRG neurons, and HUVECs. Crucially, miR-92a-3p levels in urinary exosomes correlate with adenomyosis symptoms, highlighting its potential as a non-invasive biomarker. This study offers new insights into adenomyosis progression and introduces novel diagnostic and therapeutic avenues.
Direction-dependent conductivity in planar Hall set-ups with tilted Weyl/multi-Weyl semimetals
Authors: Mandal Ipsita , Ghosh Rahul 
Published: April 2024

Abstract
We compute the magnetoelectric conductivity tensors in planar Hall set-ups, which are built with tilted Weyl semimetals (WSMs) and multi-Weyl semimetals (mWSMs), considering all possible relative orientations of the electromagnetic fields (E and B) and the direction of the tilt. The non-Drude part of the response arises from a nonzero Berry curvature in the vicinity of the WSM/mWSM node under consideration. Only in the presence of a nonzero tilt do we find linear-in-|B| terms in set-ups where the tilt-axis is not perpendicular to the plane spanned by E and B. The advantage of the emergence of the linear-in-|B| terms is that, unlike the various |B|2-dependent terms that can contribute to experimental observations, they have purely a topological origin, and they dominate the overall response-characteristics in the realistic parameter regimes. The important signatures of these terms are that they (1) change the periodicity of the response from π to 2π, when we consider their dependence on the angle θ between E and B; and (2) lead to an overall change in sign of the conductivity depending on θ, when measured with respect to the B = 0 case.
Tunable Anti-Ambipolar Vertical Bilayer Organic Electrochemical Transistor enable Neuromorphic Retinal Pathway

Published: April 2024

Abstract
Increasing demand for bio-interfaced human-machine interfaces propels the development of organic neuromorphic electronics with small form factors leveraging both ionic and electronic processes. Ion-based organic electrochemical transistors (OECTs) showing anti-ambipolarity (OFF-ON-OFF states) reduce the complexity and size of bio-realistic Hodgkin-Huxley(HH) spiking circuits and logic circuits. However, limited stable anti-ambipolar organic materials prevent the design of integrated, tunable, and multifunctional neuromorphic and logic-based systems. In this work, a general approach for tuning anti-ambipolar characteristics is presented through assembly of a p-n bilayer in a vertical OECT (vOECT) architecture. The vertical OECT design reduces device footprint, while the bilayer material tuning controls the anti-ambipolarity characteristics, allowing control of the device’s on and off threshold voltages, and peak position, while reducing size thereby enabling tunable threshold spiking neurons and logic gates. Combining these components, a mimic of the retinal pathway reproducing the wavelength and light intensity encoding of horizontal cells to spiking retinal ganglion cells is demonstrated. This work enables further incorporation of conformable and adaptive OECT electronics into biointegrated devices featuring sensory coding through parallel processing for diverse artificial intelligence and computing applications.

Abstract

The Po Nagar Towers (Thap Ba), iconic heritages of Cham culture, have stood in Nhatrang, Vietnam, for over a thousand years. The original bricks (made during the 13-14th century) and restored (during the 2000s) ones from the Po Nagar Cham Towers have been analyzed in detail by using appropriate techniques such as X-ray fluorescence, X-ray diffraction, Raman micro-spectroscopy, thermal dilatometry, etc. The compositions, structural phases, microstructure, sintering temperatures, and open porosity of the bricks have been determined for supporting the discussion on the likely technology used to make the original Cham bricks. The results obtained support the assumption that ancient original Cham bricks were made from clay, sand, plagioclases (feldspar minerals) and grog mixed with intentionally-added carbon (charcoal powder), were then fired at temperatures of 800 oC to 1000 oC forming lightweight bricks with the mass density of 1.3–1.6 kg/dm3 and the open porosity of 18–25%. The intentional use of charcoal powder in the starting materials, in combination with firing at moderate temperatures, are considered to be the key technological factors that make the ancient Cham bricks have their sandstone-like texture and high porosity to meet requirements of the rubbing joint technique in tower construction and to contribute to the sculptability and durability of Cham towers. Using these findings, one can make proper bricks for restorations of the towers, thereby avoiding problems encountered during previous restoration attempts such as erosion damage and challenging engraving.

Abstract
Background
Haemophilus influenzae is prevalent within the airways of persons with cystic fibrosis (pwCF). H. influenzae is often associated with pulmonary exacerbations (PEx) in pediatric cohorts, but in adults, studies have yielded conflicting reports around the impact(s) on clinical outcomes such as lung function decline. Accordingly, we sought to discern the prevalence, natural history, and clinical impact of H. influenzae in adult pwCF.
Methods
This single-centre retrospective cohort study reviewed all adult pwCF with H. influenzae sputum cultures between 2002 and 2016. From this cohort, persistently infected subjects (defined as: ≥3 samples with the same pulsotype and > 50% sputum culture-positive for H. influenzae in each year) were matched (1:2) to controls without H. influenzae. Demographic and clinical status (baseline health or during periods of PEx) were obtained at each visit that H. influenzae was cultured. Yearly biobank isolates were genotyped using pulsed-field gel electrophoresis (PFGE) to assess relatedness.
Results
Over the study period, 30% (n = 70/240) of pwCF were culture positive for H. influenzae, of which 38 (54%) were culture-positive on multiple occasions and 12 (17%) had persistent infection. One hundred and thirty-seven isolates underwent PFGE, with 94 unique pulsotypes identified. Four (3%) were serotype F with the rest non-typeable (97%). H. influenzae isolation was associated with an increased risk of PEx (RR = 1.61 [1.14–2.27], p = 0.006), however, this association was lost when we excluded those who irregularly produced sputum (i.e. only during a PEx). Annual lung function decline did not differ across cohorts.
Conclusions
Isolation of H. influenzae was common amongst adult pwCF but often transient. H. influenzae infection was not associated with acute PEx or chronic lung function decline.

Abstract
This paper comprehensively utilizes entropy weight method, two-way fixed effect model and TVP-SV-VAR model to investigate the impact of land finance and land financialisation on sustainable development. The results show that: as a whole, the implications of land finance and land financialization on sustainable development present inverted U-shaped characteristics conclusively. The regional heterogeneity analysis finds that inverted U-shaped impacts of land financialisation are significant in eastern and central regions, while inverted U-shaped impacts of land finance is salient in western region. Furthermore, the dynamic time-varying feature analysis implemented by different lags and time points indicating the facilitative effects of land finance and land financialization on sustainable development diminish gradually, while the inhibitory effects manifest progressively with the passage of time. We highlight that the delineation of authority and financial resources between central and local governments, optimization and reform of incentive mechanism for local government officials, and the spotlight of regional heterogeneity are paramount for effectively promotion of sustainable development.
Scoping review of fidelity strategies used in behaviour change trials delivered in primary dental care settings
Authors: Lowers Victoria , Kirby Robyn , Young Bridget , Harris Rebecca Vera 
Published: April 2024

Abstract

Background
Primary dental care settings are strategically important locations where randomised controlled trials (RCTs) of behaviour change interventions (BCIs) can be tested to tackle oral diseases. Findings have so far produced equivocal results. Improving treatment fidelity is posed as a mechanism to improve scientific rigor, consistency and implementation of BCIs. The National Institutes of Health Behaviour Change Consortium (NIH BCC) developed a tool to assess and evaluate treatment fidelity in health behaviour change interventions, which has yet to be applied to the primary dental care BCI literature.
Method
We conducted a scoping review of RCTs delivered in primary dental care by dental team members (in real-world settings) between 1980 and 2023. Eligible studies were coded using the NIH BCC checklist to determine the presence of reported fidelity strategies across domains: design, training, delivery, receipt and enactment.
Results
We included 34 eligible articles, reporting 24 RCTs. Fidelity reporting variations were found both between and within NIH BCC domains: strategy reporting ranged from 9.5–85.7% in design, 9.5–57.1% in training, 0 to 66.7% in delivery, 14.3–36.8% in receipt and 13.3–33.3% in enactment. The most reported domain was design (M = 0.45) and the least reported domain was delivery (M = 0.21). Only one study reported over 50% of the recommended strategies in every domain.
Conclusions
This review revealed inconsistencies in fidelity reporting with no evidence that fidelity guidelines or frameworks were being used within primary dental care trials. This has highlighted issues with interpretability, reliability and reproducibility of research findings. Recommendations are proposed to assist primary dental care trialists with embedding fidelity strategies into future research.
