Published: January 2024

The aim of this study was to assess the prevalence of hypertension and to investigate risk factors linked to hypertension in older adults. An observational study was conducted in a group of adults between 60 and 85 years of age, living in south-eastern Poland. In line with the specific inclusion criteria, 80 women and 29 men were enrolled for the study (109 adults). Participants’ body weight, height, and body fat percentage (BFP) were assessed using a bioelectrical impedance analysis, blood pressure was measured using automated oscillometric sphygmomanometer, moderate-to-vigorous physical activity (MVPA) and sedentary time were assessed using a tri-axial accelerometer, whereas data related to socio-economic and lifestyle factors were collected using a self-report technique. Arterial hypertension was found at a rate of 16% in participants with normal body weight, 22% in those with overweight and 85% in those with obesity. Body mass index (BMI) and BFP correlated significantly with systolic blood pressure (SBP) and diastolic blood pressure (DBP). The highest median SBP and DBP values were found in the group of participants with obesity, and the lowest values were identified in those with normal body weight. Out of all the investigated socio-economic risk factors linked to hypertension, education level was the only one that showed significant associations. A logistic regression analysis was performed to check which factors were most strongly associated with hypertension in the study group. The stepwise method showed that hypertension was more common in participants with a higher BMI, and BFP and in those who did not meet MVPA recommendation.

The objectives of our study were to assess retention rate, safety, and predictive factors for retention of subcutaneous (SC) TNF inhibitors (TNFi) (adalimumab (ADA), etanercept (ETN), golimumab (GOL), and certolizumab pegol (CZP)) in axial spondyloarthritis (axSpA) depending on the line of treatment in real-life conditions. A multicentre retrospective observational study was conducted including 552 patients fulfilling the ASAS criteria for axSpA followed in the RIC-France register who began SC-TNFi between 01/01/13 and 08/31/2018 for a total of 824 prescriptions. Taking all lines of treatment into account, GOL had a significantly higher retention rate compared with ADA, ETN, and CZP with a mean retention length of 59 months. As first-line bDMARDs, GOL had a significantly higher retention rate compared with ADA and ETN. ETN had the best retention rate when prescribed as at least 3rd bDMARD. Taking all lines of treatment into account, female sex, peripheral disease, BASDAI at initiation, and line of treatment were predictive factors for treatment cessation. Primary inefficiency was the most frequent reason for treatment cessation. In conclusion, GOL showed the highest retention rate in axSpA. Male sex, absence of peripheral disease, and early line of prescription were associated with better SC-TNFi retention in axSpA.
Calcitonin gene-related peptide regulates periodontal tissue regeneration
Authors: Miki Koji , Takeshita Noboru , Yamashita Motozo , Kitamura Masahiro , Murakami Shinya
Published: January 2024

Calcitonin gene-related peptide (CGRP), a neuropeptide composed of 37 amino acids secreted from the sensory nerve endings, reportedly possesses various physiological effects, such as vasodilation and neurotransmission. Recently, there have been increasing reports of the involvement of CGRP in bone metabolism; however, its specific role in the pathogenesis of periodontitis, particularly in the repair and healing processes, remains to be elucidated. Therefore, this study aimed to investigate dynamic expression patterns of CGRP during the destruction and regeneration processes of periodontal tissues in a mouse model of experimental periodontitis. We also explored the effects of CGRP on periodontal ligament cells, which can differentiate to hard tissue-forming cells (cementoblasts or osteoblasts). Our findings demonstrated that CGRP stimulation promotes the differentiation of periodontal ligament cells into hard tissue-forming cells. Experimental results using a ligature-induced periodontitis mouse model also suggested fluctuations in CGRP expression during periodontal tissue healing, underscoring the vital role of CGRP signaling in alveolar bone recovery. The study results highlight the important role of nerves in the periodontal ligament not only in sensory reception in the periphery, as previously known, but also in periodontal tissue homeostasis and tissue repair processes.
Study on the design calculation method and construction control method of suction drum foundation for guided frame platform
Authors: Xin Zhang , Yuansong Li , Mingyue Liu , Shaoqi Ye , Yong Zhao , Zhaoxian Li
Published: January 2024

Currently, a standardized design and calculation specification for suction drum foundations has yet to exist in China. The engineering design currently depends mainly on the subjective understanding and engineering experience of the designers, which can be considered somewhat blind and subjective. In this paper, we utilize the offshore wind power project in Yangjiang City, Guangdong Province, as our case study. Building upon domestic and international research results, relevant investigations, design specifications, and engineering applications in related fields, we conduct a systematic study on the design calculation and construction control technology of the suction drum foundation. The document presents the design calculation and inspection of the suction drum foundation. Building on this foundation, we propose a sinking feasibility analysis method and a parameter value method for the suction drum foundation calculation. We also examine the suction drum foundation construction process, examining its control parameters, technology, and standards. Finally, based on the measured data from six four-barrel guided frame platform suction drum foundations that were successfully installed, the proposed design and control method are evaluated, and their effectiveness is verified. The results of this study can provide valuable references for the design and construction of similar suction drum foundation platforms.
Combined lime and biochar application enhances cowpea growth and yield in tropical Alfisol
Authors: Adekiya Aruna Olasekan , Ayorinde Bolajoko Bisola , Ogunbode Timothy
Published: January 2024

It is essential to increase the pH of tropical soils in order to reduce acidity and promote soil and crop productivity. Therefore, experiments were carried out in 2020 and 2021 to assess the impacts of biochar and lime on the chemical properties, growth, nodulation, and yield of cowpea (Vigna unguiculata). The study involved various levels of lime (CaCO3) and wood biochar (ranging from 0 to 10 t ha−1), organized in a factorial combination. The treatments were arranged in a randomized complete block design and replicated three times. The application of lime and biochar, either separately or in combination, led to improvements in soil chemical properties such as pH, nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), sodium (Na), magnesium (Mg), and cation exchange capacity (CEC), as well as enhancements in the growth, nodulation, and yield of cowpea when compared to the control. Lime and biochar alone and combined reduced exchangeable acidity (Al + H) relative to the control. Cowpea yield increased with lime rate up to a point, but then decreases. The highest cowpea yield is achieved at a lime rate of 2.5 t ha−1, whereas cowpea yield increased as the Biochar rate increased from 0 up to 10 t ha−1. There was a significant correlation between pH and cowpea pod weight in both years (2020 and 2021). The R values were − 0.615 and − 0.444 for years 2020 and year 2021 respectively at P < 0.05. At higher lime levels combined with biochar, there were considerable reductions in cowpea yield, and this decrease can be attributed to unfavorable soil pH conditions. Relative to 2.5 t ha−1 lime + 5 t ha−1 biochar, 10 t ha−1 lime + 10 t ha−1 biochar, reduced cowpea grain yield by 853% in 2020 and 845% in 2021. Since there were no significant differences between the effects of 2.5 t ha−1 lime + 5 t ha−1 biochar, 2.5 t ha−1 lime + 7.5 t ha−1 biochar, and 2.5 t ha−1 lime + 10 t ha−1 biochar applications on cowpea yield, therefore to prevent waste of Biochar, 2.5 t ha−1 lime + 5 t ha−1 biochar is recommended for production of cowpea.

Published: January 2024

Circular RNAs (circRNAs) are a family of endogenous RNAs that have become a focus of biological research in recent years. Emerging evidence has revealed that circRNAs exert biological functions by acting as transcriptional regulators, microRNA sponges, and binding partners with RNA-binding proteins. However, few studies have identified coding circRNAs, which may lead to a hidden repertoire of proteins. In this study, we unexpectedly discovered a protein-encoding circular RNA circCCDC7(15,16,17,18,19) while we were searching for prostate cancer related chimeric RNAs. circCCDC7(15,16,17,18,19) is derived from exon 19 back spliced to exon 15 of the CCDC7 gene. It is significantly downregulated in patients with high Gleason score. Prostate cancer patients with decreased circCCDC7(15,16,17,18,19) expression have a worse prognosis, while linear CCDC7 had no such association. Overexpressed circCCDC7(15,16,17,18,19) inhibited prostate cancer cell migration, invasion, and viability, supporting classification of circCCDC7(15,16,17,18,19) as a bona fide tumor suppressor gene. We provide evidence that its tumor suppressive activity is driven by the protein it encodes, and that circCCDC7(15,16,17,18,19) encodes a secretory protein. Consistently, conditioned media from circCCDC7(15,16,17,18,19) overexpressing cells has the same tumor suppressive activity. We further demonstrate that the tumor suppressive activity of circCCDC7(15,16,17,18,19) is at least partially mediated by FLRT3, whose expression also negatively correlates with Gleason score and clinical prognosis. In conclusion, circCCDC7(15,16,17,18,19) functions as a tumor suppressor in prostate cancer cells through the circCCDC7-180aa secretory protein it encodes, and is a promising therapeutic peptide for prostate cancer.
Susceptibility to acute cognitive dysfunction in aged mice is underpinned by reduced white matter integrity and microgliosis

Published: January 2024

Age is a significant but heterogeneous risk factor for acute neuropsychiatric disturbances such as delirium. Neuroinflammation increases with aging but the determinants of underlying risk for acute dysfunction upon systemic inflammation are not clear. We hypothesised that, with advancing age, mice would become progressively more vulnerable to acute cognitive dysfunction and that neuroinflammation and neuronal integrity might predict heterogeneity in such vulnerability. Here we show region-dependent differential expression of microglial transcripts, but a ubiquitously observed primed signature: chronic Clec7a expression and exaggerated Il1b responses to systemic bacterial LPS. Cognitive frailty (vulnerability to acute disruption under acute stressors LPS and double stranded RNA; poly I:C) was increased in aged animals but showed heterogeneity and was significantly correlated with reduced myelin density, synaptic loss and severity of white matter microgliosis. The data indicate that white matter disruption and neuroinflammation may be key substrates of the progressive but heterogeneous risk for delirium in aged individuals.
Order from disorder phenomena in BaCoS2
Authors: Lenz Benjamin , Fabrizio Michele , Casula Michele
Published: January 2024

At TN ≃ 300K the layered insulator BaCoS2 transitions to a columnar antiferromagnet that signals non-negligible magnetic frustration despite the relatively high TN, all the more surprising given its quasi two-dimensional structure. Here, we show, by combining ab initio and model calculations, that the magnetic transition is an order-from-disorder phenomenon, which not only drives the columnar magnetic order, but also the inter-layer coherence responsible for the finite Néel transition temperature. This uncommon ordering mechanism, actively contributed by orbital degrees of freedom, hints at an abundance of low energy excitations above and across the Néel transition, in agreement with experimental evidence.
The slip surface mechanism of delayed failure of the Brumadinho tailings dam in 2019
Authors: Zhu Fangyuan , Zhang Wangcheng , Puzrin Alexander M.
Published: January 2024

The 2019 Feijão dam failure in Brumadinho, Brazil, claimed 270 lives and caused enormous environmental damage. A special feature of this failure was that it took place three years after the tailings disposal was terminated, which should have allowed sufficient time for the material to consolidate and increase its strength. Here we propose a basic physical mechanism of a delayed slip surface growth along weak layers of fine tailings within the dam body. Using accurate numerical modelling of all stages of the evolution of the Feijão dam, we show how this growth was preconditioned by dam construction and tailings discharge history and further driven by creep deformation during the post-closing stage, until the slip surfaces reached their critical length, resulting in their unstable propagation and the rapid collapse of the entire dam. Main factors controlling the time of failure have been identified, facilitating future risk assessment for decommissioned tailings dams.
Integration of vanHAX downstream of a ribosomal RNA operon restores vancomycin resistance in a susceptible Enterococcus faecium strain

Published: January 2024

During the genomic characterisation of Enterococcus faecium strains (n = 39) collected in a haematology ward, we identified an isolate (OI25), which contained vanA-type vancomycin resistance genes but was phenotypically susceptible to vancomycin. OI25 could revert to resistance when cultured in the presence of vancomycin and was thus considered to be vancomycin-variable. Long-read sequencing was used to identify structural variations within the vancomycin resistance region of OI25 and to uncover its resistance reversion mechanism. We found that OI25 has a reduced ability to positively regulate expression of the vanHAX genes in the presence of vancomycin, which was associated with the insertion of an IS6-family element within the promoter region and the first 50 bp of the vanR gene. The vancomycin-resistant revertant isolates constitutively expressed vanHAX genes at levels up to 36,000-fold greater than OI25 via co-transcription with a ribosomal RNA operon. The vancomycin-resistant revertants did not exhibit a significant growth defect. During VRE outbreaks, attention should be paid to contemporaneous vancomycin-susceptible strains as these may carry silent vancomycin resistance genes that can be activated through genomic rearrangements.

Varying Syntax to Enhance Verb-Focused Intervention for 30-Month-Olds With Language Delay: A Concurrent Multiple Baseline Design
Authors: Nicholas Katrina , Grierson Tobie , Helen Priscilla , Miller Chelsea , Van Horne Amanda Owen
Published: January 2024

Purpose:

The purpose of this study is to determine if 2.5-year-olds with language delay would learn verbs (
spill
) when presented with varying syntactic structure (“The woman is spilling the milk“/”The milk is spilling”;
milk
= patient or theme) in a therapeutic context. Children with language delay have proportionally small inventories of verbs, which limits expressive language development. Children who have typical language development learn verbs more robustly when presented with alternating arguments than with a single argument structure.

Method:

Three toddlers with expressive language delay (29–30 months of age) participated in a verb-focused treatment study using a concurrent multiple baseline design. Participants were shown action videos accompanied by sentences with varied argument structure for each target verb. To assess learning pre- and posttreatment, participants were asked to demonstrate actions corresponding to each verb.

Results:

Visual inspection and tau analyses reveal significant posttreatment gains of target verbs taught with varying argument structures.

Conclusions:

Our results indicate that learning verbs with high variability of argument roles may facilitate a strong link between lexical representations of verbs and their syntactic structures. Using argument structure variability to teach verbs as an intervention strategy has great potential and should be tested further in larger group studies.
Research on hierarchical and sub‐area network control technology of LEO giant constellation
Authors: He Ci , Zhang Yasheng , Yu Yuejun , Li Cong
Published: January 2024

The low‐earth‐orbit (LEO) telecommunication constellation network is foreseen as a merging interconnection method for future sixth‐generation (6G) systems. However, how to implement constellation system composition, consider network design constraints and envision application scenarios in a low‐orbit giant constellation system, is still an open problem. In this paper, by exploring the constellation characteristics in the future LEO systems, the design of hierarchical and sub‐area network control architecture for giant constellation is first suggested. After that, a detailed research on the partition mechanism of control domain for the giant LEO constellation systems is implemented. To make the architecture design and partition mechanism feasible, the hierarchical and domain controlling flow is also discussed. Finally, a performance verification method is present with elaborate numerical results and evaluations. The results verified the correctness and effectiveness of the proposed network control architecture and partition mechanism.
Error analysis for face coded modulation system
Authors: Akuon Peter O.
Published: January 2024

This paper discusses a new mapping scheme known as face coded modulation (FCM) system. In FCM, peak energy symbols are mapped onto an innermost ring according to the eight sockets in the human face, that is, brain, mouth, nostrils, eyes and ears. For example, FCM is formed when the constellation diagram from M‐ary quadrature amplitude modulation (MQAM) system is modified to reduce peak‐to‐average power ratio (PAPR) by relocating the four corner symbols of the MQAM, with peak energy, to the innermost ring in a way that forms the figure of a cross. Unlike APSK, FCM mapping introduces non‐uniform sequence of symbols on the ring, face width factor and multiple modulator circuits that can be used to lower power requirements for high power amplifiers (HPA) as used in MQAM transmission systems. Symbol error rate (SER) for FCM is calculated and the results compared with MQAM and MPSK. It is shown that at equal energy efficiency, FCM scheme has a better response to errors than both MPSK and MQAM and a better energy efficiency due to lowered PAPR than MQAM. Moreover, the simulation results exhibit a tight match for the proposed analytical framework when assessed under Additive White Gaussian Noise (AWGN) channel.
Latency and accuracy optimization for binary neural network inference with locality‐aware operation skipping
Authors: Lee S.‐J. , Kim T.‐H.
Published: January 2024

This letter presents a novel technique to optimize latency and accuracy for the inference based on binary neural network (BNN). The effects of the spatial locality in feature maps on latency and accuracy are analyzed in the BNN inference with the previous operation‐skipping method. A regularization‐based technique is proposed to adjust the locality with the aim of further reducing latency and improving accuracy of the previous method. In the CIFAR10 classification task, 11.62% latency reduction or 0.77% accuracy increase can be achieved when optimizing for each individually. When optimizing for both simultaneously, 5.58% latency reduction and 0.59% accuracy increase can be achieved.

While recent years have witnessed the unprecedented success of deep convolutional neural networks (CNNs) and vision transformers in single‐image super‐resolution (SISR), the degradation assumptions are simple and usually bicubic downsampling. Thus, their performances will drop dramatically when the actual degradation does not match this assumption, and they lack the capability to handle multiple degradations (e.g. Gaussian noise, bicubic downsizing, and salt & pepper noise). To address the issues, in this paper, the authors propose a joint SR model (JIRSR) that can effectively handle multiple degradations in a single model. Specifically, the authors build the parallel Transformer and CNN branches that complement each other through bidirectional feature fusion. Moreover, the authors also adopt a random permutation of different kinds of noise and resizing operations to build the training datasets. Extensive experiments on classical SR, denoising, and multiple degradation removal demonstrate that the authors’ JIRSR achieves state‐of‐the‐art (SOTA) performance on public benchmarks. Concretely, the authors’ JIRSR outperforms the second‐best model by 0.23 to 0.74 dB for multiple degradations removal and is 0.20 to 0.36 dB higher than the SOTA methods on the Urban100 dataset under the ×4 SR task.

In this investigation, a nanostructured Cu2O thin film absorber layer is electrodeposited, exploring the impact of varying negative applied voltages and deposition time. Notably, the Cu2O thin film demonstrated optimal absorbance at −0.95 V, contrasting sharply with a minimum at −0.97 V. The authors' findings underscore that the peak absorbance was achieved at −0.95 V, coinciding with the lowest transmittance observed after 80 min of deposition, aligning with a maximal absorption coefficient of 21 × 103 cm−1. At a deposition time of 5 min, the Cu2O thin film exhibited a noteworthy maximum Urbach energy of 2.00 eV and a minimum steepness parameter of 0.013. In contrast, the lowest Urbach energy was recorded at 0.34 eV, with the highest steepness parameter occurring at an applied voltage of 0.93 V. Furthermore, this study revealed a gradual increase in the refractive index with higher applied voltages, reaching its pinnacle at −1.5 V. These results collectively emphasize the nuanced interplay between applied voltage, deposition time and the optical properties of the nanostructured Cu2O thin film. The observed trends hold significant implications for optimizing the performance of thin film absorber layers, particularly in the context of enhancing absorbance and tailoring optical characteristics for specific applications.

A novel magnetic coupling resonance wireless power transfer (MCR‐WPT) system, which has constant‐current (CC) and constant‐voltage (CV) output characteristics suiting for batteries charging, is proposed in this paper. The hybrid compensation topology is adopted; in detail, the LCL‐P circuit topology is used in the CC mode, while the LCL‐S topology is used in the CV mode. Since the switchable components are only located at the receiving side of WPT, the switching can be controlled by the receiving side based on the batteries’ state without data communication between transmitting side and receiving side. Furthermore, an adjustable frequency tuning method which is based on proportion integration (PI) closed‐loop controlled by the transmitting side is applied to maximize the current of the transmitting coil. This method also can solve the frequency splitting problem, improving the stability and power of the system while the distance of the two sides changes. The performance of the proposed WPT system is verified by simulation and experiments. The experiment results show that the load current variation is less than 3% in the CC mode and the load voltage changes less than 5% in the CV mode, as the load resister changes from 5 to 20 Ω.

Published: January 2024

Currently, Unmanned Aerial Vehicle (UAV) plays a huge role, especially fixed-wing UAVs that can be used for various missions such as wide area survey work. It can also carry heavy loads over a long distance. And use less power. However, this type of UAV requires a relatively large runway or landing area. If the landing is used as a net landing, it will need a lot of space to install a net anyway. On the other hand, if using a multirotor UAV or Hybrid model (tilt-wing) that uses less space for take-off and landing. Nevertheless, there will be a limit on speed. If the wind is strong, it will not be able to fly and unable to carry enough load. Therefore, the organizers have foreseen the problem and fix the take-off and landing of fixed-wing UAV by using hand launch method for take-off while landing will use deep stall landing (GPS + Camera) that uses GPS to determine the radius zone 25 meters from the target to land in the start deep stall, in which this landing method will nose up until the angle of attack (AOA) is enough rates to cause the fixed-wing to lose lifting force and land at the specified point using camera to detect landing targets and adjusting the control surface on the fixed-wing elevator to land as close as possible to the specified point. It must be able to land closer to the target than using GPS or the pilot only. The results revealed that GPS landings had an average radius between the landing point and the target being 15.59 m. Pilot landings had an average radius between the landing point and the target being 14.71 m and GPS + Camera landing had an average the radius between the landing point and the target being 7.22 m. If the landing distance is calculated only the longitudinal axis, so GPS landing distance was 13.1 m. Pilot landing was 8.7 m and the GPS + Camera landing was 5.37 m. Furthermore, deep stall landing (GPS + Camera) can land closer than using GPS and pilot only.

Current aircraft was designed with winglet at the tip. Winglets reduce the drag and improve fuel efficiency and range. The winglets have been in use for nearly 90 years, but it have been remained fixed. This paper presents the effects of winglet Cant angle on the aerodynamic characteristics of the wing. Winglet Cant Angle (WCA) is the angle between the vertical exis and the winglet. Computational Fluid Dynamics (CFD) has been used to simulate the Cant angles at constant angle of attack of 0⁰. In this paper the Cant angle was varied from 105⁰, 88⁰, 75⁰, 60⁰, 50⁰, 45⁰, 35⁰ and the simulation works were performed at three different Flight levels of Sea level, 10000 and 15000 meters. The analysis analysis at 100 m/s velocity shows that Cant angle of 45⁰ is the best performing Winglet while Cant 60⁰ is the lowest performance in overall lift to drag Ratio. Similar results were obtained when Turbulent Kinematic Viscosity were measured at 20 m behind the wing. Flow visualization also showed the similar results Cant angle 450 is the best performance compared to other angles. For the best performing winglet, the lift to drag Ratio was lowest for perpendicular crosswinds. This study shows the effect of only winglet cant angle, however other factors involved to impact the performance of winglet are, Winglet height, winglet sweep angle, Winglet Cant angle, Winglet Toe angle, and crosswinds. To implement the best overall drag coefficient winglet, the optimization must be done mid-air. While calculating the parameters, the best most optimized winglet can be chosen for cruising flight level.

Published: January 2024

In this research, zebrafish larvae models were employed to evaluate the activity of antioxidant enzymes—GSH, GPX, and GST—in response to treatments with doxorubicin and a novel drug, diosgenin. Solutions for the two exposure groups, Doxorubicin (30 µM) and diosgenin (37.8 µM), were prepared by diluting stock solutions in egg water. The zebrafish maintenance and egg collection process involved housing breeding groups in a specific spawning tank with a 1:1 male-to-female ratio. The tank was equipped with a collection box and mesh at the bottom to gather embryos and prevent consumption by adult fish. The study comprised two groups, each with 15 samples, totaling 30 samples. Group 1 assessed doxorubicin’s effects on larval zebrafish, while Group 2 evaluated diosgenin’s impact. Embryos, with n=15 per plate, were sorted into petri plates for each exposure group and exposed to diosgenin from 4 hpf to 96 hpf (Hours Post Fertilisation). All conditions aligned with the OECD guidelines for fish embryo toxicity assays, ensuring the study’s validation. Every experiment was conducted in triplicate. Statistical analysis utilised the Statistical Packages for the Social Sciences (SPSS) software. The analysis maintained a confidence ratio of 95%, a threshold of 0.01, an 80% G power, and an enrolment ratio of 1. The findings revealed that zebrafish larvae treated with the novel drug, diosgenin, exhibited heightened levels of GPx, GSH, and GST compared to the doxorubicin-treated group. This increase was statistically significant with a p-value of 0.000 (p<0.05). Consequently, this study demonstrated that diosgenin and doxorubicin treatments upregulated antioxidant enzyme activity—GPX, GSH, and GST—in zebrafish larvae, highlighting diosgenin as an effective antioxidant agent.
