Authors: Haidari Zaki , Ahmad Shehla Ufaq , Knipp Stephan , Turaev Iskandar , El Gabry Mohamed
Published: June 2024

Objectives: Infective endocarditis of the aortic valve complicated by annular abscess is a challenging problem and often requires patch reconstruction after surgical debridement of the abscess cavity. Filling the remaining cavity with antibiotics is advocated to prevent recurrent endocarditis. This study aimed at evaluating the role of local antibiotics in patients with aortic valve infective endocarditis complicated by annular abscess. Methods: Between January 2012 and December 2021, all consecutive patients with aortic valve infective endocarditis complicated by annular abscess undergoing cardiac surgery and annular patch reconstruction were included. Patients receiving local antibiotics were compared with patients without local antibiotics. The primary endpoints were the incidence of recurrent endocarditis, re-operation, and mortality during two-year follow-up. Results: A total of 41 patients with aortic valve infective endocarditis complicated by annular abscess underwent surgical patch reconstruction after radical debridement. In total, 20 patients received local antibiotics in the abscess cavity and 21 patients were treated without local antibiotics. The most common causative microorganisms were the staphylococci species and the most common location of the abscess was the non-coronary annulus. During two-year follow-up, one patient in each group developed recurrent endocarditis (p > 0.99) and both patients were reoperated (p > 0.99). Two-year mortality was 30% in the local antibiotic group and 24% in the control group (p = 0.65). Conclusions: Radical debridement and patch reconstruction of the aortic annulus in patients with aortic valve infective endocarditis complicated by annular abscess is an effective surgical strategy. Filling of the remaining abscess cavity with antibiotic seems not to affect the rate of recurrent endocarditis, reoperation, and mortality during two-year follow-up.
Partitioning Uncertainty in Model Predictions from Compartmental Modeling of Global Carbon Cycle
Authors: Gazioğlu Suzan
Published: June 2024

Our comprehension of the real world remains perpetually incomplete, compelling us to rely on models to decipher intricate real-world phenomena. However, these models, at their pinnacle, serve merely as close approximations of the systems they seek to emulate, inherently laden with uncertainty. Therefore, investigating the disparities between observed system behaviors and model-derived predictions is of paramount importance. Although achieving absolute quantification of uncertainty in the model-building process remains challenging, there are avenues for both mitigating and highlighting areas of uncertainty. Central to this study are three key sources of uncertainty, each exerting significant influence: (i) structural uncertainty arising from inadequacies in mathematical formulations within the conceptual models; (ii) scenario uncertainty stemming from our limited foresight or inability to forecast future conditions; and (iii) input factor uncertainty resulting from vaguely defined or estimated input factors. Through uncertainty analysis, this research endeavors to understand these uncertainty domains within compartmental models, which are instrumental in depicting the complexities of the global carbon cycle. The results indicate that parameter uncertainty has the most significant impact on model outputs, followed by structural and scenario uncertainties. Evident deviations between the observed atmospheric CO2 content and simulated data underscore the substantial contribution of certain uncertainties to the overall estimated uncertainty. The conclusions emphasize the need for comprehensive uncertainty quantification to enhance model reliability and the importance of addressing these uncertainties to improve predictions related to global carbon dynamics and inform policy decisions. This paper employs partitioning techniques to discern the contributions of the aforementioned primary sources of uncertainty to the overarching prediction uncertainty.
Fucoidan as a Promising Drug for Pain Treatment: Systematic Review and Meta-Analysis
Authors: Huerta Miguel Á. , Tejada Miguel Á. , Nieto Francisco R.
Published: June 2024

Fucoidan is a polymer of L-fucose and L-fucose-4-sulphate naturally found in marine sources that inhibits p-selectin, preventing neutrophil recruitment to the site of injury. Fucoidan is employed in many studies as a tool to investigate the contribution of neutrophils to pain, showing analgesic effects. We performed a systematic review and meta-analysis to quantify the analgesic effects of pretreatment with fucoidan reported in the available preclinical studies. In addition, we summarized the articles which have studied the therapeutic effects of fucoidan in pathological pain at preclinical and clinical levels. The results of this systematic review reveal that pretreatment with fucoidan is a powerful tool which reduces neutrophil infiltration by 70–90% at early time points. This meta-analysis showed that preventative treatment with fucoidan produced a significant pain reduction. In addition, several preclinical studies have observed that fucoidan treatment reduces the pain that is associated with various pathologies. Finally, fucoidan has also been tested in several clinical trials, with some degree of analgesic efficacy, but they were mostly small pilot studies. Considering all the above information, it can be concluded that fucoidan is not only a preclinical tool for studying the role of neutrophils in pain but also a promising therapeutic strategy for pain treatment.

Published: June 2024

Elderberry (Sambucus nigra L.) is a widespread deciduous shrub, of which the fruits (elderberries) are used in the food industry to produce different types of dietary supplement products. These berries have been found to show multiple bioactivities, including antidiabetic, anti-infective, antineoplastic, anti-obesity, and antioxidant activities. An elderberry extract product, Sambucol®, has also been used clinically for the treatment of viral respiratory infections. As the major components, phenolic compounds, such as simple phenolic acids, anthocyanins and other flavonoids, and tannins, show promising pharmacological effects that could account for the bioactivities observed for elderberries. Based on these components, salicylic acid and its acetate derivative, aspirin, have long been used for the treatment of different disorders. Dapagliflozin, an FDA-approved antidiabetic drug, has been developed based on the conclusions obtained from a structure–activity relationship study for a simple hydrolyzable tannin, β-pentagalloylglucoside (β-PGG). Thus, the present review focuses on the development of therapeutic agents from elderberries and their small-molecule secondary metabolites. It is hoped that this contribution will support future investigations on elderberries.

Published: June 2024

Piper attenuatum Buch-Ham, a perennial woody vine belonging to the Piperaceae family, is traditionally used in Southeast Asia for treating various ailments such as malaria, headache, and hepatitis. This study described the isolation and identification of three new compounds, piperamides I-III (1–3), which belong to the maleimide-type alkaloid skeletons, along with fifteen known compounds (4–18) from the methanol extract of the aerial parts of P. attnuatum. Their chemical structures were elucidated using spectroscopic methods (UV, IR, ESI-Q-TOF-MS, and 1D/2D NMR). All the isolates were evaluated for their ability to inhibit IL-6 activity in the human embryonic kidney-Blue™ IL-6 cell line and their cytotoxic activity against ovarian cancer cell lines (SKOV3/SKOV3-TR) and chemotherapy-resistant variants (cisplatin-resistant A2780/paclitaxel-resistant SKOV3). The compounds 3, 4, 11, 12, 17, and 18 exhibited IL-6 inhibition comparable to that of the positive control bazedoxifene. Notably, compound 12 displayed the most potent anticancer effect against all the tested cancer cell lines. These findings highlight the importance of researching the diverse activities of both known and newly discovered natural products to fully unlock their potential therapeutic benefits.

Published: June 2024

Newly synthesized 7-chloro-4-aminoquinoline–benzimidazole hybrids were characterized by NMR and elemental analysis. Compounds were tested for their effects on the growth of the non-tumor cell line MRC-5 (human fetal lung fibroblasts) and carcinoma (HeLa and CaCo-2), leukemia, and lymphoma (Hut78, THP-1, and HL-60) cell lines. The obtained results, expressed as the concentration at which 50% inhibition of cell growth is achieved (IC50 value), show that the tested compounds affect cell growth differently depending on the cell line and the applied dose (IC50 ranged from 0.2 to >100 µM). Also, the antiplasmodial activity of these hybrids was evaluated against two P. falciparum strains (Pf3D7 and PfDd2). The tested compounds showed potent antiplasmodial activity, against both strains, at nanomolar concentrations. Quantitative structure–activity relationship (QSAR) analysis resulted in predictive models for antiplasmodial activity against the 3D7 strain (R2 = 0.886; Rext2 = 0.937; F = 41.589) and Dd2 strain (R2 = 0.859; Rext2 = 0.878; F = 32.525) of P. falciparum. QSAR models identified the structural features of these favorable effects on antiplasmodial activities.
Numerical Analyses of Perforation and Formation Damage of Sandstone Gas Reservoirs
Authors: Liang Hao , Zhao Zhihong , Jin Haozeng
Published: June 2024

Shaped charge perforation is an important technology for sandstone gas reservoirs. In the process of shaped charge perforating, the initial permeability and porosity of the formation are greatly reduced, directly affecting oil and gas production. This paper uses smooth particle hydrodynamics (SPH) and finite element methods (FEMs) to study the formation damage caused by the shaped charge perforation. In this perforation simulation, the impact characteristics of the metal jet formed by the liner are coupled with the damage characteristics of the sandstone. A new mathematical model is proposed to describe the damage of permeability and porosity based on the Morris and Xue models. The simulated results show that a large-scale abdominal section appears at the perforation site, and the axis of the hole tilts with the increase in the perforation depth. The porosity damage at the perforation site is the greatest, up to 60%, while the permeability recovers to 90% of its initial state after pressure relief. The degree of porosity damage decreases with the increase in negative pressure, and when the negative pressure is 30 MPa, it may cause a large amount of sand production.
Downlink Transmissions of UAV-RIS-Assisted Cell-Free Massive MIMO Systems: Location and Trajectory Optimization
Authors: Zhang  Qi , Zhao  Jie , Zhang  Rongcheng , Yang  Longxiang
Published: June 2024

In this paper, we investigate a cell-free massive multiple-input multiple-output (CF-mMIMO) system with a reconfigurable intelligent surface (RIS) carried by an unmanned aerial vehicle (UAV), called the UAV-RIS. Compared with the RIS located on the ground, the UAV-RIS has a wider coverage that can reflect all signals from access points (APs) and user equipment (UE). By correlating the UAV location with the Rician K-factor, we derive a closed-form approximation of the UE achievable downlink rate. Based on this, we obtain the optimal UAV location and RIS phase shift that can maximize the UE sum rate through an alternating optimization method. Simulation results have verified the accuracy of the derived approximation and shown that the UE sum rate can be significantly improved with the obtained optimal UAV location and RIS phase shift. Moreover, we find that with a uniform UE distribution, the UAV-RIS should fly to the center of the system, while with an uneven UE distribution, the UAV-RIS should fly above the area where UEs are gathered. In addition, we also design the best trajectory for the UAV-RIS to fly from its initial location to the optimal destination while maintaining the maximum UE sum rate per time slot during the flight.

This study investigates gender differences in core muscle morphology among elite alpine skiers using ultrasonography, highlighting significant disparities that could influence training and injury prevention strategies. Methods: A cross-sectional design was employed, examining ultrasound imaging (USI) in 22 elite skiers (11 male, 11 female) to assess the thickness of the external oblique (EO), internal oblique (IO), transversus abdominis (TrAb), and rectus abdominis (RA) muscles. Results: Significant differences were noted, with male skiers displaying greater muscle thickness, particularly in the right IO and RA and left IO, EO, TrAb, and RA. Conclusions: These findings suggest that male and female skiers may require different training approaches to optimize performance and reduce injury risks. This research contributes to a deeper understanding of the physical demands on elite skiers and underscores the need for gender-specific training regimens to enhance athletic outcomes and prevent injuries.

Published: June 2024

This study reassesses an overview of the potential of the radio frequency (RF)-based state diagnostics of three-way catalysts (TWC) based on a previous study with an emphasis on the defect chemistry of the catalyst material during reoxidation and reduction. Some data are based on the previous works but are newly processed, and the signal parameters resonant frequency and inverse quality factor are evaluated with respect to applicability. The RF-based method uses electromagnetic resonances in a cavity resonator to provide information on the storage level of the oxygen storage component. The analysis focuses on a holistic investigation and evaluation of the major effects influencing the RF signal during operation. On the one hand, the response to the oxygen storage behavior and the resolution of the measurement method are considered. Therefore, this study merges original data from multiple former publications to provide a comprehensive insight into important measurement effects and their defect chemistry background. On the other hand, the most important cross-sensitivities are discussed and their impact during operation is evaluated. Additionally, the effect of catalyst aging is analyzed. The effects are presented separately for the two resonant parameters: resonant frequency and (unloaded) quality factor. Overall, the data suggest that the quality factor has a way higher signal quality at low temperatures (<400 °C) and the resonant frequency is primarily suitable for high operating temperatures. At most operating points, the quality factor is even more robust against interferences such as exhaust gas stoichiometry and water content. Correctly estimating the catalyst temperature is the most important factor for reliable results, which can be achieved by combining the information of both resonant signals. In the end, the data indicate that microwave-based state diagnosis is a powerful system for evaluating the oxygen storage level over the entire operating range of a TWC. As a research tool and in its application, the system can therefore contribute to the improvement of the emission control of future gasoline vehicles.

In recent years, advancements in the Internet of Things (IoT), manufacturing processes, and material synthesis technologies have positioned flexible sensors as critical components in wearable devices. These developments are propelling wearable technologies based on flexible sensors towards higher intelligence, convenience, superior performance, and biocompatibility. Recently, two-dimensional nanomaterials known as MXenes have garnered extensive attention due to their excellent mechanical properties, outstanding electrical conductivity, large specific surface area, and abundant surface functional groups. These notable attributes confer significant potential on MXenes for applications in strain sensing, pressure measurement, gas detection, etc. Furthermore, polymer substrates such as polydimethylsiloxane (PDMS), polyurethane (PU), and thermoplastic polyurethane (TPU) are extensively utilized as support materials for MXene and its composites due to their light weight, flexibility, and ease of processing, thereby enhancing the overall performance and wearability of the sensors. This paper reviews the latest advancements in MXene and its composites within the domains of strain sensors, pressure sensors, and gas sensors. We present numerous recent case studies of MXene composite material-based wearable sensors and discuss the optimization of materials and structures for MXene composite material-based wearable sensors, offering strategies and methods to enhance the development of MXene composite material-based wearable sensors. Finally, we summarize the current progress of MXene wearable sensors and project future trends and analyses.

Authors: Wang Yan , Wang Yongshan , Li Jie , Wang Xiaoli
Published: June 2024

Fourier Ptychographic Microscopy (FPM) is a microscopy imaging technique based on optical principles. It employs Fourier optics to separate and combine different optical information from a sample. However, noise introduced during the imaging process often results in poor resolution of the reconstructed image. This article has designed an approach based on a residual local mixture network to improve the quality of Fourier ptychographic reconstruction images. By incorporating channel attention and spatial attention into the FPM reconstruction process, the network enhances the efficiency of the network reconstruction and reduces the reconstruction time. Additionally, the introduction of the Gaussian diffusion model further reduces coherent artifacts and improves image reconstruction quality. Comparative experimental results indicate that this network achieves better reconstruction quality, and outperforming existing methods in both subjective observation and objective quantitative evaluation.
Multi-Armed Bandit-Based User Network Node Selection
Authors: Gao Qinyan , Xie Zhidong
Published: June 2024

In the scenario of an integrated space–air–ground emergency communication network, users encounter the challenge of rapidly identifying the optimal network node amidst the uncertainty and stochastic fluctuations of network states. This study introduces a Multi-Armed Bandit (MAB) model and proposes an optimization algorithm leveraging dynamic variance sampling (DVS). The algorithm posits that the prior distribution of each node’s network state conforms to a normal distribution, and by constructing the distribution’s expected value and variance, it maximizes the utilization of sample data, thereby maintaining an equilibrium between data exploitation and the exploration of the unknown. Theoretical substantiation is provided to illustrate that the Bayesian regret associated with the algorithm exhibits sublinear growth. Empirical simulations corroborate that the algorithm in question outperforms traditional ε-greedy, Upper Confidence Bound (UCB), and Thompson sampling algorithms in terms of higher cumulative rewards, diminished total regret, accelerated convergence rates, and enhanced system throughput.
Energy-Efficient, Cluster-Based Routing Protocol for Wireless Sensor Networks Using Fuzzy Logic and Quantum Annealing Algorithm
Authors: Wang Hongzhi , Liu Ke , Wang Chuhang , Hu Huangshui
Published: June 2024

The main limitation of wireless sensor networks (WSNs) lies in their reliance on battery power. Therefore, the primary focus of the current research is to determine how to transmit data in a rational and efficient way while simultaneously extending the network’s lifespan. In this paper, a hybrid of a fuzzy logic system and a quantum annealing algorithm-based clustering and routing protocol (FQA) is proposed to improve the stability of the network and minimize energy consumption. The protocol uses a fuzzy inference system (FIS) to select appropriate cluster heads (CHs). In the routing phase, we used the quantum annealing algorithm to select the optimal route from the CHs and the base station (BS). Furthermore, we defined an energy threshold to filter candidate CHs in order to save computation time. Unlike with periodic clustering, we adopted an on-demand re-clustering mechanism to perform global maintenance of the network, thereby effectively reducing the computation and overhead. The FQA was compared with FRNSEER, BOA-ACO, OAFS-IMFO, and FC-RBAT in different scenarios from the perspective of energy consumption, alive nodes, network lifetime, and throughput. According to the simulation results, the FQA outperformed all the other methods in all scenarios.

Published: June 2024

Wireless sensor networks (WSNs) are attracting increasing research interest due to their ability to monitor large areas independently. Their reliability is a crucial issue, as it is influenced by hardware, data, and energy-related factors such as loading conditions, signal attenuation, and battery lifetime. Proper selection of sensor node positions is essential to maximise system reliability during the development of products equipped with WSNs. For this purpose, this paper presents an approach to estimate WSN system reliability during the development phase based on the analysis of measurements, using strain measurements in finite element (FE) models as an example. The approach involves dividing the part under consideration into regions with similar strains using a region growing algorithm (RGA). The WSN configuration is then analysed for reliability based on data paths and measurement redundancy resulting from the sensor positions in the identified measuring regions. This methodology was tested on an exemplary WSN configuration at an aircraft wing box under bending load and found to effectively estimate the hardware perspective on system reliability. Therefore, the methodology and algorithm show potential for optimising sensor node positions to achieve better reliability results.

The dress size recommendation system has become an important feature in e-commerce applications to help users choose the right size when shopping online. Therefore, we introduce a dress size recommendation system that uses the Naive Bayes algorithm for e-commerce applications. The dress size recommendation system using the Naive Bayes algorithm in this e-commerce application is expected to improve the user's online shopping experience. After the model is trained, when a user accesses an e-commerce application and searches for clothing products, the system will use the information collected from the user such as gender, height, weight, chest circumference and usual clothing sizes as input features. Then, the Naive Bayes model will calculate the probability that a user with these characteristics will choose a certain shirt size.

Under five nutritional status is a measure used to assess the nutritional level of children at an early age. In determining nutritional status using anthropometric measurements which involve physical measurements such as body weight and height. Then the threshold (Z-Score) is calculated and the nutritional status category of a child can be determined. this is of course more rigid because the measurement standards are firmer. Fuzzy logic allows for a more refined classification in determining nutritional status. In fuzzy logic, variables are not only limited to a few discrete categories such as thin, normal or fat. On the other hand, fuzzy logic introduces a continuous degree of membership which allows for a more refined classification based on the degree of membership in each category. This research is proven to produce predictions that are relatively correct, then testing has been carried out and it is proven from the test results that the application runs well.

Authors: Burgan Samar
Published: June 2024

Background: Oral cavity malignancies mostly affect older adults and the elderly. Adolescents and young adults (15–39 years) are less affected. However, there is a paucity of studies addressing the epidemiology of oral cavity malignancies in these age groups.Objectives: To describe the epidemiology of oral cavity malignancies in adolescents and young adults in Jordan.Patients and methods: The records of ordinarily resident patients in Jordan aged between 15 and 39 years, with histologically confirmed oral cavity malignancies, between the years 2000 and 2017, were analyzed. The frequency of each type of malignancy, incidence, annual percentage, site, age, sex and trends were analyzed.Results: Between the years 2000 and 2017, 406 adolescents and young adults fulfilled the inclusion criteria. This comprised 2.9% of all cancers in this age category during the same period. The mean age was 28.5 ± 7.6 years. Some 59.4% were male and 40.6% female. Regarding marital status, 34.2% were single, 61.6% married, and 0.7% divorced, while the marital status of 3.4% was unknown. Most (98.3%) were Jordanian nationals. The number of cases increased from 4.7% in 2000 to 6.2% in 2017, with no statistically significant trend. The overall age-adjusted incidence rate was 7.8 per 1,000,000. It decreased from 9.4 in 2000 to 6.2 in 2017, with no statistically significant trend over the study period. Nasopharyngeal cancer was the most common (56.9%), followed by cancers of the salivary gland (16.7%), tongue (10.3%), gums (6.2%), lips (5.2%), hypopharynx (2.7%), other oral cavity and pharynx (1.0%), oropharynx (0.5%), floor of mouth (0.2%), and tonsils (0.2%). Overall, the incidence of cancers of the oral cavity and pharynx was higher in males. The incidence of cancers of the nasopharynx, tongue, and lips was higher in males, while salivary gland cancer was higher in females. The incidence of cancers of the gum, hypopharynx, and pharynx did not differ between the sexes.Conclusions: The incidence of oral malignancies in adolescents and young adults in Jordan is relatively high compared to worldwide estimates but is not increasing. Risk factors for these malignancies should be the target of primary prevention interventions.

Generations shaped in the process of formation of an information/digital society have significant differences from previous generations, which were formed in the conditions of an industrial society at the level of values. The aim of this study is to identify specific differences in the perception of social, existential, and transcendental fears in Generation Z (also known as centennials, zoomers, etc., born in the late 1990s - early 2000s). Based on an information-communication approach, qualitative research (focus groups) of centennials - students of universities in the city of Ufa on the topic of fear perception was conducted. It was found that fear of the future information/digital society, shared by the older generations, is not characteristic of Generation Z. Development in a digital environment has fostered qualities such as pragmatism, network solidarity, network rootedness, and a positive attitude towards the digital future. Generation Z has shown a decrease in fear towards the development of digital technologies, artificial intelligence, and genetic engineering. At the same time, they are concerned about existential fears related to external forces, such as environmental pollution, global warming, and the risk of economic and political crises. In general, representatives of the digital society are optimistic, hoping that they can solve society's problems with the support of digital technologies. The identified change in the structure of fear perception has both academic and practical significance, allowing for the expansion and deepening of research in this area, as well as increasing the effectiveness of interaction with Generation Z.

A minimax routing problem with decomposition elements is considered. In the simplest case, it is supposed that the whole set of tasks is divided into a sum of two subsets (clusters), and execution of tasks from the second subset can be started only after the completion of all tasks from the first subset. For above-mentioned two-cluster problem, an algorithm has been constructed for finding the optimal compositional solution, including a route (permutation of task indices) and a starting point, which is based on the use of a broadly understood dynamic programming. Based on this approach, an algorithm was also constructed to solve the routing problem in the case of an arbitrary ordered finite set of clusters. The algorithm was implemented on a PC, and a computational experiment was carried out. Possible applications may be associated with some logistics tasks in small aviation, when it is necessary to ensure visits to many points by one vehicle (airplane, helicopter) with a limited non-stop flight range.

Marmara Adası, Marmara Denizi’nin güneybatısında yer alan ve Balıkesir iline bağlı olan bir adadır. Yüz ölçümü olarak ülkemizin ikinci büyük adası olması, mermer madenciliğindeki başat rolü ve turizm potansiyeli adayı önemli bir konuma getirmektedir. Tarihi kaynaklardan edindiğimiz bilgilere göre Marmara Adası jeopolitik konumu ve tüm Akdeniz ülkelerine ihraç ettiği mermeri sayesinde bölgeye hâkim olan uygarlıklar için de her zaman önemli olmuştur. Arkeolojik verilerin, yerleşim tarihini Eski Çağ’a kadar dayandırdığı Marmara Adası’nda Antik Yunan, Roma, Bizans ve Osmanlı İmparatorluğu gibi farklı medeniyetler hüküm sürmüş ve adada çok uluslu bir demografi meydana gelmiştir. 1922 yılında gerçekleşen zorunlu göçe kadar çoğunluğu Rumlardan oluşan gayrimüslim halk ve Müslüman halk bir arada yaşamıştır. Bu kültürel etkileşimin yerel mimari üzerinde etkisi olduğu muhakkaktır. Bu çalışmada adanın önemli yerleşim yerlerinden biri olan Asmalı köyünün mimari mirası incelenecektir. Günümüze ulaşan ve ulaşmayan konut yapıları, cami, kilise ve manastır gibi dini yapıları ile su yapıları ele alınarak Asmalı köyünün tarihi ve sosyal yapısının yerel mimarisine olan etkisi araştırılacaktır. Çalışmanın amacı Asmalı köyü yerel mimari örneklerini yapı tipi, plan, malzeme ve teknik açısından inceleyip bu yapıların mimarlık tarihi yönünden önemlerini ortaya koyarak literatüre kazandırmaktır.
