Key Construction Technologies for Steel Truss Bridges in High Water Level and High Flow Velocity Conditions: A Case Study for Shoupanyan Bridge
Authors: Liu Haiyong , Li Ming , Dai Yuelong , Ou Mintao 
Published: July 2024

AbstractTemporary steel truss bridges are increasingly used in engineering projects due to the large-scale construction and development of sea-crossing bridges. However, the construction of these bridges is greatly affected by environmental factors and can face significant challenges when dealing with complex conditions such as fast currents, water depth, and large fluctuations in water level. Therefore, advanced construction techniques are necessary to overcome these challenges. This paper discusses the design, analysis, and construction of a steel truss bridge over water under high water level and rapid flow conditions, using the Shupan Yan Bridge construction project as an example. The paper proposes novel techniques for drilled piles, lateral support, and bridge deck structure. Additionally, a detailed finite element model is established. The results of the finite element analysis demonstrate the suitability and practicality of the novel technology design proposed in this study for constructing steel truss bridges in complex water environments. The technology improves safety during construction. The research findings can provide guidance for similar projects.

Authors: Li Zhiluo , Cheng Shijie , Yu Peng 
Published: July 2024

AbstractConventional numerical methods face major challenges in simulating the complex failure process of soil slopes effectively and accurately. This paper introduces a tension-shear composite failure criterion that elucidates the compound failure mechanisms of soil slopes, realized in the ABAQUS software through the secondary development of a user subroutine and simulated via the extended finite element method (XFEM) module. This method is utilized to simulate the process of soil slope failure under conditions that include heaping load at the crest and excavation at the toe, accompanied by analyses of the failure patterns. The methodology's validity and accuracy are substantiated through comparison with experimental data. The proposed approach adeptly captures the initiation, propagation, and ultimate penetration of cracks during the slope failure process, offering an effective method for simulating the entire slope failure.
Numerical Analysis of Large-Diameter Shield Tunneling Disturbance Considering Stratum Strength Anisotropy
Authors: Jiang Hao , Liu Wu , Cheng Jin , Yao Huayan , Li Renjie , Shang Jinhang 
Published: July 2024

AbstractThe anisotropic characteristics of natural strata could have a significant effect on the tunneling disturbance of shield tunnels. A shield tunneling disturbance simulation method considering the effect of stratum strength anisotropy is proposed in this study. The proposed method adopts the microstructure tensor theory to characterize the anisotropy effects of the stratum material cohesion c and the internal friction angle φ, and finely simulates the shield tunneling processes, including the shield shell advancement, the lining installation, and the shield tail grouting. The shield tunneling refined simulation method is validated by simulating the tunneling process in a certain section of a super-large-diameter shield tunnel in Wuhu City, Anhui Province, China, with good agreement between the simulated surface settlements on the axial and transverse profiles of the excavated tunnel after tunneling to different lining-ring numbers and the monitoring data. On this basis, according to the anisotropic compression strength property of the layered stratum in other sections, the effect of the stratum shear strength anisotropy on the shield tunneling disturbance is analyzed. The shield tunneling-induced surface settlement under the case considering stratum shear strength parameters anisotropy is obviously greater than that without accounting for the anisotropy, demonstrating the importance of considering strata anisotropy caused by geological structures during shield tunneling disturbance modeling.

Published: July 2024

AbstractThe flow process of underground water drainage pipeline is of great significance to the flood prevention and drainage of substation, and to ensure the demand of power supply. In this paper, the control test and numerical simulation of the flow process of underground drainage pipeline in substation are carried out. Based on the basic equations of water volume (continuity) and momentum of the full flow in pipelines, combined with the Preissmann slit assumption, the governing equations and their discrete forms of one-dimensional full flow are derived, and a one-dimensional full flow model is established. On this basis, the control experiment is carried out by using the flow process of drainage pipe, and the model is verified by the measured results. The results show that the one-dimensional full-flow model based on Preissmann slit hypothesis can effectively simulate the flow process of underground drainage pipes in substations, and provide technical support for flood prevention and waterlogging early warning of substations in humid areas.

Authors: Chen Ling-pei , Wang Tian-cheng 
Published: July 2024

AbstractThis paper presents a three-dimensional geological Building Information Modeling (BIM) method aimed at addressing safety simulation and rational construction parameter challenges in shield tunneling under varying geological conditions. Incorporating the characteristics of metro shield tunnel modeling, this study utilized both Revit and Dynamo software for modeling. The integration of information on completeness and depth, essential for meeting the requirements of shield tunnel construction, was achieved in the model. This integrated information was then effectively transferred to the finite element simulation model, addressing issues related to communication among participating units and the transmission of information between the BIM model and the finite element model. The research findings demonstrate that the three-dimensional geological BIM model, grounded in shield construction simulation, achieves the automation of shield construction object representation and information updating, thereby enhancing the level of informatization in shield construction.
Health Monitoring and Evaluation Method of Civil Engineering Structure Based on Machine Learning
Authors: Wang Xinyao 
Published: July 2024

AbstractThe health monitoring and assessment of civil engineering structures are important for ensuring structural safety and can Sustainability is critical. Traditional monitoring methods often require a lot of time and resources, and have some limitations in real-time and accuracy. In order to overcome these problems, this paper proposes a method of health monitoring and evaluation of civil engineering structures based on machine learning. This method combines sensor data with machine learning algorithm to realize real-time and accurate monitoring and evaluation of structural health status. By training and learning the data of existing civil engineering structures, the correlation model between structural health and sensor data is established. Through field experiments and simulation verification, the results show that the proposed method can effectively detect structural abnormalities, early warning potential faults of the structure, and provide scientific decision-making basis for engineers, so as to improve the safety and reliability of civil engineering structures.
Sublinear Elliptic Equations with Unbounded Coefficients in Lipschitz Domains
Authors: Hirata Kentaro 
Published: July 2024

AbstractThis paper is concerned with the homogeneous Dirichlet problem for a sublinear elliptic equation with unbounded coefficients in a Lipschitz domain. Bilateral a priori estimates for positive solutions and a priori upper estimates for their gradients are presented as a byproduct of the boundary Harnack principle. These estimates allow us to show the uniqueness of a positive solution of the homogeneous Dirichlet problem under no information about normal derivatives unlike in smooth domains.
Immediate Versus Delayed Low-Stakes Questioning: Encouraging the Testing Effect Through Embedded Video Questions to Support Students’ Knowledge Outcomes, Self-Regulation, and Critical Thinking
Authors: Wong Joseph T. , Richland Lindsey Engle , Hughes Bradley S. 
Published: July 2024

AbstractIn light of the educational challenges brought about by the COVID-19 pandemic, there is a growing need to bolster online science teaching and learning by incorporating evidence-based pedagogical principles of Learning Experience Design (LXD). As a response to this, we conducted a quasi-experimental, design-based research study involving nN = 183 undergraduate students enrolled across two online classes in an upper-division course on Ecology and Evolutionary Biology at a large R1 public university. The study extended over a period of 10 weeks, during which half of the students encountered low-stakes questions immediately embedded within the video player, while the remaining half received the same low-stakes questions after viewing all the instructional videos within the unit. Consequently, this study experimentally manipulated the timing of the questions across the two class conditions. These questions functioned as opportunities for low-stakes content practice and retention, designed to encourage learners to experience testing effect and augment the formation of their conceptual understanding. Across both conditions, we assessed potential differences in total weekly quiz grades, page views, and course participation among students who encountered embedded video questions. We also assessed students’ self-report engagement, self-regulation, and critical thinking. On average, the outcomes indicated that learners exposed to immediate low-stakes questioning exhibited notably superior summative quiz scores, increased page views, and enhanced participation in the course. Additionally, those who experienced immediate questioning demonstrated heightened levels of online engagement, self-regulation, and critical thinking. Moreover, our analysis delved into the intricate interplay between treatment conditions, learners’ self-regulation, critical thinking, and quiz grades through a multiple regression model. Notably, the interaction between those in the immediate questioning condition and self-regulation emerged as a significant factor, suggesting that the influence of immediate questioning on quiz grades varies based on learners’ self-regulation abilities. Collectively, these findings highlight the substantial positive effects of immediate questioning of online video lectures on both academic performance and cognitive skills within an online learning context. This discussion delves into the potential implications for institutions to continually refine their approach in order to effectively promote successful online science teaching and learning, drawing from the foundations of pedagogical learning experience design paradigms and the testing effect model.

AbstractPresent investigation was undertaken to assess the composition of bioactive compounds within various parts of methanolic extracts from mulberry plants utilizing both High-Performance Liquid Chromatography (HPLC) and spectrophotometric methodologies. Furthermore, the antioxidant potential was evaluated through assays including 2,2-diphenyl-1-picrylhydrazyl (DPPH), Ferric Reducing Antioxidant Power (FRAP), β-carotene bleaching (BCBA), and Hydroxyl Radical Scavenging Activity (HRSA). This research incorporated the analysis of the fruit, root, shoot, and leaf of the mulberry (Morus alba L.) Cv. Ichinose. Findings from the investigation revealed that levels of total phenols (533.8 ± 15.6 mg/100 g) and flavonoids (232.3 ± 7.1 mg/100 g) were notably higher in fruit compared to root, while total ascorbic acid content (70.9 ± 3.1 mg/100 g) was significantly elevated in the leaf. The fruit exhibited a significantly higher concentration of total anthocyanins (142.5 ± 3.1 mg/100 g), whereas the leaf contained a substantial amount of total carotenoids (5.8 ± 0.3 mg/100 g). Predominant phenolic acids detected in mulberry included ferulic acid, m-coumaric acid, syringic acid, caffeic acid, chlorogenic acid, and gallic acid. Quercetin and isoquercetin were identified as the major flavonoids in mulberry fruits. In terms of anthocyanins, cyanidin-3-rutinoside (25.6 ± 2.3 mg/100 g) and cyanidin-3-glucoside (16.4 ± 2.1 mg/100 g) were the primary anthocyanins present in the fruit. The main carotenoid found in the leaf was beta-carotene, with levels reaching 2.1 ± 0.3 mg/100 g. Fruit displayed the highest antioxidant activity among all parts examined. Comparison of the EC50 values of fruit (EC50 = 174.2 ± 2.2 µg/mL), root (EC50 = 179.6 ± 2.3 µg/mL), and shoot (EC50 = 189.4 ± 2.1) suggested that these segments of the mulberry plant could potentially function as antioxidants and could exhibit a greater hydroxyl radical scavenging effect than standard antioxidants.

Published: July 2024

Abstract

Background
Pain in cancer patients has enormous impact on their quality-of-life. Radiation therapy (RT) is a cornerstone in cancer treatment. The objective of the PREDORT study is to estimate the prevalence of pain in patients attending at Radiation Oncology (RO) Services.

Methods
A prospective, multicenter study was designed for patients treated at the RO Services of reference hospitals. Patients were seen in their initial Nursing consultation, during which key data was collected, including demographic and comorbidities data, medical history, and oncological and pain characteristics. The study has received approval from the Ethics Committee of Navarra, and all patients signed the Informed Consent.

Results
Of the 860 participating patients, 306 reported some type of pain, which implies a prevalence of 35.6%. Of them, 213 identified a cause of oncological origin. The proportion of pain was similar among sexes, but the proportion of non-cancer pain was higher among women (p < 0.05). Regarding pain intensity, the magnitude of breakthrough pain in patients with oncological pain is nearly 1 point greater than in patients with non-oncological pain (7.53 vs 6.81; p = 0.064). Cancer pain is more likely to be limiting of normal life than non-cancer pain (59% versus 38%, p < 0.001). Regarding analgesic treatment, only 60/306 patients (19.6%) were receiving strong opioids. There were 68 patients with pain without any treatment (22.2%).

Conclusions
The prevalence of pain in cancer patients referred to RO services is 35.6%, with the prevalence of exclusively oncological pain being 24.8%. Understanding and addressing oncological pain is essential to provide comprehensive care to patients.
A qualitative analysis of male actors in amateur pornography: motivations, implications and challenges
Authors: Yaakobovitch Tal , Bensimon Moshe , Idisis Yael 
Published: July 2024

AbstractAmateur Pornography (AP) is a new phenomenon that emerged a few decades ago and is distinctly different from Professional Pornography (PP). Yet, academic literature that focuses on AP hardly exists. This qualitative study focuses on male AP actors’ lived experience, including their motivations, implications and ways of coping with its challenges. Semi-structured interviews with 27 male AP actors revealed five themes: (1)AP as a unique genrethat promotes diverse human body appearance, free choice, and profit as its secondary motive; (2)personal backgroundthat includes sexual abuse during childhood and unmet childhood emotional needs; (3)moral reasons for involvement in AP, including challenging sexual misperceptions, preventing sexual harmfulness, and promoting education for healthy sexuality and gender equality; (4)implications of involvement in AP, including positive implications such as increased self-esteem and gaining admiration and appreciation, as well as negative implications, such as impaired interpersonal relationships, social stigmatization, harassments and persecutions, and physical and psychological work injuries; and (5)ways of coping with sex work’s particular difficulties, such as the AP actors’ emotional reliance on their romantic partners, developing an artistic perspective, hiding one’s involvement in AP, and adopting a “work persona”. This research suggests that the participants’ involvement in AP was based on free choice and motivated by ideological reasons. Their strategies for coping with the negative implications of their involvement in AP reflect their sense of potency which is contrary to victimhood that is associated with impotency and helplessness.
Hydrops regression after vestibular denervation - longitudinal magnetic resonance study in patients with severe Meniere’s disease treated with vestibular neurectomy
Authors: Jasińska-Nowacka Agnieszka , Lachowska Magdalena , Wnuk Emilia , Niemczyk Kazimierz 
Published: July 2024

Abstract
Objectives
The aim was to evaluate endolymphatic hydrops in patients with severe Ménière’s disease (MD) before and after vestibular neurectomy to verify if vestibular denervation results in hydrops regression.

Methods
Magnetic resonance imaging was performed after intravenous gadolinium injection in twenty patients with unilateral definite MD before and after the vestibular neurectomy. Clinical symptoms and audiovestibular tests were evaluated. Follow-up intervals ranged from 18 to 35 months after the surgery.

Results
Endolymphatic hydrops were visualized in all patients in the preoperative scans. After the vestibular neurectomy, all patients presented a complete resolution of vertigo episodes. Regression of the endolymphatic hydrops was observed in 35% and 15% of cases analyzing cochlea and vestibule, respectively. In 71.43% of patients with utricular herniation into the lateral semicircular canal, withdrawal of the hernia was visualized. Asymmetrical contrast enhancement in the cochlea regressed in 17.64% of cases. Analyzing all the parameters collectively, in 60% of patients, partial regression of at least one of the radiological signs was confirmed in the follow-up examination. No progression of the endolymphatic hydrops was visualized after the surgery in either the cochlea or the vestibule.

Conclusions
Vestibular neurectomy is an effective treatment, eliminating vertigo attacks and improving the quality of life in patients with MD. Magnetic resonance imaging of the inner ear allows visualization of changes in endolymphatic hydrops degree after treatment. Regression of the endolymphatic hydrops after vestibular neurectomy suggests that vestibular denervation may effectively halt the progression of the endolymphatic space dilatation and result in hydrops regression.
Emotional Competences in Adolescents Exposed to Colombian Armed Conflict During Their Childhood
Authors: León-Rodríguez Diego Armando , Moncaleano Catalina 
Published: July 2024

AbstractObjective: Analyse the mediation role of emotional competences on behavior problems in adolescents exposed to Armed-Conflict Childhood Adversities (ACCA). Method: Families with adolescent children who studied in three schools in the municipality of Soacha, Colombia, were invited to participate in the study. One hundred and sixty-one participants were selected and pooled into three groups according to their Adverse Childhood Experiences (ACE) scores: lower-ACE (LACE), higher-ACE (HACE), and ACCA using the Adverse Childhood Experiences Questionnaire for Adolescents (ACE-QA). The Emotion Recognition Task, the Empathy for Pain Task, and the Child Behavior Checklist assessed teenagers’ emotional functioning. Results: Teenagers exposed to ACCA more frequently experienced childhood adversities such as domestic violence, child abuse, and parental neglect. Moreover, these adolescents were less accurate in discriminating angry faces, reported higher control perception after social stressors, were more rigorous in punishing those who intentionally harmed others, and showed more internalizing behavior problems. In the mediational model, we found that: the control perception after social stress mediated the reduction of depressive symptoms in adolescents with ACCA history. Additionally, inaccuracy in perceiving angry faces and harsh punishment toward behaviors that intentionally harm others mediated the presence of thinking problems, anxiety, and rule-breaking behaviors. Conclusions: Colombian adolescents who experienced ACCA showed specific changes in their emotional competences, which mediate the parental report of behavioral problems. These results indicate the need for more focused interventions aimed at improving the emotional competences and mental health of adolescent victims of armed conflicts.

Published: July 2024

Abstract
Background
During the COVID-19 pandemic, the Chinese government implemented nationwide public health interventions to control its spread. However, the impact of these measures on other infectious diseases remains unclear.

Methods
The incidence of three types of notifiable infectious diseases in China were analyzed between 2013 and 2021. The seasonal Mann-Kendall test and Mann-Kendall mutation test were employed to examine trends and mutations in the time series. Based on the counterfactual inference, historical incidence rates were employed to construct SARIMA models and predict incidence between January 2020 and December 2021. Differences between reported and predicted incidences during the pandemic were compared using the Mann-Whitney U test.

Results
Between 2013 and 2019, the incidence rate of three types of notifiable infectious diseases fluctuated between 494.05/100,000 and 550.62/100,000. No discernible trend was observed for types A and B infectious diseases (Z = −1.344, P = 0.18). A significant upward trend was observed for type C infectious diseases (Z = 2.56, P = 0.01). In 2020, the overall incidence rate of three types of notifiable infectious diseases decreased to 367.08/100,000. Compared to predicted values, the reported incidence of three types of infectious diseases was, on average, 30.05% lower in 2020 and 16.58% lower in 2021.

Conclusion
The public health interventions implemented during the pandemic had a positive consequence on the prevention and control of other infectious diseases, with a particularly notable effect on type C infectious diseases. Among the diseases with different transmission routes, respiratory diseases and gastrointestinal or enteroviral diseases decreased significantly.
