Study on the influence of the fully enclosed barrier on the vortex-induced vibration performance of a long-span highway–railway double-deck truss bridge

Long-span highway–railway double-deck truss bridges are mostly located in urban centers, where noise pollution and traffic safety issues have a great impact. The fully enclosed barrier has excellent sound insulation and windproof performance and has been widely used in double-deck truss bridges in recent years. However, the large volume and the low air permeability rate will affect the aerodynamic characteristics of the bridge, resulting in vortex-induced vibration (VIV). To analyze how the fully enclosed barrier influences the highway–railway bridge VIV performance, this study analyzes the Huangjuetuo Yangtze River Bridge, combined with the wind tunnel test and the numerical calculation method to study different variations of the static three-force coefficient, the change of VIV response, and its influence mechanism after setting the fully enclosed barrier. The results show that the static three-force coefficient of the double-deck truss bridge changes significantly, the drag coefficient increases, and the absolute values of the lift coefficient and the moment coefficient decrease after the fully enclosed barrier is set. The aerodynamic performance of the bridge is significantly reduced after the fully enclosed barrier is set, and the amplitude and range of the VIV response are increased. Vertical bending VIV increased by an average of 58.5%, and torsional VIV increased by an average of 21.9%. Considering driving comfort and safety, attention should be paid to the double-deck truss bridge with a fully enclosed barrier.

Impact of the COVID-19 Pandemic on Saudi Parents' Perceptions Toward Their Children's Oral Health: A Cross-Sectional Study.

Background The coronavirus disease 2019 (COVID-19) markedly affected all aspects of life. Pediatric dentistry and oral health of children faced a challenging situation during the pandemic. Aim This study aimedto assess the attitude of Saudi parents toward their children's oral health and dental treatment during the COVID-19 pandemic. Methods This online-based cross-sectional study was conducted using a structured questionnaire adopted from previous studies with some modifications. It was distributed among 385 Saudi parentsrecruited through social media. It included questions regarding demographic data, parents' attitudes toward their children's dental care and dental visits during the COVID-19 pandemic, their fear level and willingness to take their children to dental appointments, and the parent's perception of dental clinics with regard to the COVID-19 spread. Descriptive statistics and the chi-squaretest were used; statistical significance was set at a p-value < 0.05. Results Different levels of fear of the pandemic were expressed by Saudi parents, with 42 (10.9%) showing maximum fear while 36 (9.3%) reported no fear. Although about half of the parentsstated that their children experienced dental pain during the pandemic, only 97 (25.1%) looked for dental care and were assisted. There was a significant association (p < 0.05) between the fear level with the family income and parents' willingness to take their children to dental appointments. Conclusions COVID-19 has hada great impact on parents' attitudes towards their children's oral health. A high percentage of Saudi parents' stated that they would take their children to dental clinics during the pandemic only for urgent treatment and severe pain.

The effect of calcination gas atmosphere on the structural organization of Ru/Ce0.75Zr0.25O2 catalysts for CO2 methanation

In this study, supported 5 wt% Ru/Ce0.75Zr0.25O2 catalysts were prepared by sorption-hydrolytic deposition technique, followed by calcination under different conditions, namely in reductive H2/N2 (Ru/CeZr_red) and oxidative air (Ru/CeZr_ox) atmospheres. A thorough characterization of the catalysts was carried out by XRD, CO chemisorption, HRTEM, Raman spectroscopy, XPS, and in situ DRIFTS. The findings showed that the choice of the calcination atmosphere has a great impact on the structural organization of the catalyst. Calcination in air results in the formation of the larger crystalline RuO2 particles, which tend to enlarge upon reduction under CO2 methanation conditions. The reductive treatment results in a much higher dispersion of supported Ru species and a more pronounced metal-support interaction (MSI). In the Ru/CeZr_red catalyst, a large amount of atomic scale Ru species was detected along with metallic Ru nanoparticles and clusters. However, it was found that the superiority of the Ru/CeZr_red catalyst in the Ru dispersion did not result in the significant advantage in the CO2 methanation activity. In situ DRIFTS results suggested that the MSI affects the ability of Ru species to adsorb and activate reagent molecules, in particular, enhances the adsorption strength of the intermediate CO species.

Analysis of the Advantages and Disadvantages of Commercializing Sports Leagues Based on NBA Alliance

Through the analysis of the advantages and disadvantages of commercialization in the NBA league, the conclusion drawn in this article is that the increase in the degree of commercialization ion of the league has a significant impact on the league's visibility, commercial value, economic income, and overall competitive level. It can also drive the development of the entire sports industry and the formation of a country's sports culture. In the process of commercialization, corresponding problems also arise. From the perspective of fairness, certain matches in the league may be affected by commercial interests in the terms of the fairness of referee calls and penalties. Sometimes, concessions may be made for the sake of the viewing and smoothness of the game, which can damage the interests of one team and violate the spirit of fairness and justice in sports. In addition, gray industries such as gambling and soccer are constantly emerging, which have a great impact and harm on society and are difficult to completely avoid. After decades of development, the NBA has successfully captured the development dividends of the media and Internet era, completed its own brand building, and pushed the NBA to the world. The NBA continuously improves its internal rules, introduces a series of policies, works closely with sponsors in various fields, and make it the world's number one professional basketball league. In order for China's professional basketball league to develop and grow on the path of professionalization and commercialization, in addition to learning and drawing on the NBA business model, it is also necessary to combine its own basic national conditions and basketball development status, formulate basketball league and culture with Chinese characteristics.

Patterns and unique features of infantile cholestasis among Arabs.

Most of the literature on infantile cholestasis (IC) originated from Caucasian and Asian populations. The differential diagnosis of IC is very broad, and identification of etiology is challenging to clinicians because the list includes many entities with overlapping clinical, biochemical, and histological features. Thus, a structured, stepwise diagnostic approach is required to help early recognition and prompt evaluation and management of treatable causes of cholestasis. (1) To determine the differential diagnosis of IC among Saudi population and (2) to evaluate the usefulness of a diagnostic algorithm that has been tailored by the authors to the local practice. All infants with onset of cholestasis before 12 months of age (2007 and 2020) were identified and included if they underwent extensive work up to exclude infectious, structural, metabolic, endocrine, infiltrative, and familial causes. Our diagnostic pathway allowed a definite diagnosis in 373 of the included 533 cases; 160 (30%) were labelled as "idiopathic neonatal hepatitis" (INH) [i.e., overall 70% detection rate]. However, when considering the cases that underwent extensive investigations including advanced gene testing (415 of the 533), the yield of the diagnostic algorithm was 90% (373/415). Familial cholestasis group was the most common in 20% (107/533), and biliary atresia and neonatal-onset Dubin Johnson syndrome contributed to 6% each. The genetic/hereditary causes of cholestasis contributed to 58% of the diagnosed cases (217/373). No single case of alpha-1 antitrypsin deficiency was diagnosed. Forty-nine infants with cholestasis presented with liver failure (9%). Our study highlights several unique features and causes of IC among Arabs which could have a great impact on the differential diagnosis process and the choice of laboratory tests used in the clinical setting.

Effects of Bony Pelvic and Prostate Dimensions on Surgical Difficulty of Robot-Assisted Radical Prostatectomy: An Original Study and Meta-analysis.

Due to the deep location of the prostate within the pelvic cavity, procedures of robot-assisted radical prostatectomy (RARP) might be challenged by the prostate size and the limited pelvic cavity space. This study aimed to investigate the roles of bony pelvic and prostate dimensions in RARP procedures by an original study coupled with a meta-analysis. In the original study, patients undergoing multiport RARP between 2021 and 2022 were consecutively assessed. The associations of anatomic features with operative time (OT), estimated blood loss (EBL), and positive surgical margin (PSM) were evaluated using linear and logistic regression analyses as well as restricted cubic spline (RCS) analysis. Based on machine-learning algorithms, this study established predictive models for surgical difficulty and interpreted the model using SHapley Additive exPlanation (SHAP). In the meta-analysis, three databases were searched for eligible studies. Quantitative syntheses were subsequently performed. Overall, 219 patients were enrolled in the original study. Prostate volume (PV) and the prostate volume-to-pelvic cavity index (PCI) ratio (PV-to-PCI ratio) were significantly associated with longer OT (P < 0.05). In the RCS models, U-shaped associations were observed between the prostate anteroposterior diameter (PAD) and OT, and between the prostate height (PH) and EBL, and an L-shaped association was observed between the anteroposterior diameter of the pelvic inlet (API) and EBL. The XGBoost model was superior to the logistic regression model in predicting prolonged OT. The meta-analysis demonstrated that greater PV was significantly associated with longer OT (β = 0.20; 95% confidence interval [CI] 0.12-0.27; odds ratio [OR] = 1.05; 95% CI 1.00-1.11), and a smaller PV could increase the risk of PSM (OR = 0.82; 95% CI 0.77-0.88). A large prostate within a narrow and deep pelvis might suggest increased surgical difficulty of RARP. The size of the pelvic inlet also had a great impact on RARP. For PAD and PH, there seemed to be an optimal range with the lowest surgical difficulty. Machine-learning models based on the XGBoost algorithm could be successfully applied to predict the surgical difficulty of RARP.

Effect of Q-learning on the evolution of cooperation behavior in collective motion: An improved Vicsek model

There have been numerous studies on collective behavior, among which communication between agents can have a great impact on both the payoff and the cost of making decisions. Research usually focuses on how to improve the collective synchronization rate or accelerate the process of cooperation under given communication cost constraints. In this context, evolutionary game theory (EGT) and reinforcement learning (RL) arise as essential frameworks for tackling this intricate problem. In this study, an adapted Vicsek model is introduced, wherein agents exhibit varying movement patterns contingent on their chosen strategies. Each agent gains a payoff determined by the advantages of collective motion juxtaposed with the cost of communicating with neighboring agents. Individuals choose the objective agents based on the Q-learning strategy and then adapt their strategies following the Fermi rule. The research reveals that the utmost level of cooperation and synchronization can be attained at an optimal communication radius after applying Q-learning. Similar conclusions have been drawn from research on the influence of random noise and relative cost. Different cost functions were considered in the study to demonstrate the robustness of the proposed model and conclusions under a wide range of conditions.

Diagenesis of Cenomanian–Early Turonian and the Control of Carbonate Reservoirs in the Northern Central Arabian Basin

The carbonate reservoirs of Cenomanian–Early Turonian in the northeastern Central Arabian Basin hold considerable oil reserves and are great contributors to oil production. Diagenesis have a great impact on carbonate reservoir petrophysical properties, microstructure, and heterogeneity. By integrating cores, cast thin sections, regular core analysis, CT, and isotopes, this study provides an improved understanding of diagenesis in the Cenomanian–Early Turonian and its effect on carbonate reservoirs. The results showed that three diagenetic environments were identified in the Cenomanian–Early Turonian based on texture, structure, cement, crystal form, and crystal size, which were marine environment, meteoric environment, and burial environment. Six diageneses were identified based on residual bioclastic, secondary pores, calcite quantity, dolomite size, and stylolite, namely dissolution, cementation, micritization, dolomitization, compaction, and pressure solution. A micritization model in high energy sediment, a dolomitization model in burrows, and a comprehensive diagenetic model were established. It concluded that dissolution during meteoric environment is most favorable to reservoir physical properties, while cementation is least favorable. The cement content controls the microstructure and petrophysical property. Micritization is detrimental to the petrophysical properties, and the micrite it forms are distributed in the interparticle pores, reducing the reservoir property deposited in high energy environment. Dolomitization is less developed in substrate but widely developed in burrows, which result in the physical properties of the burrows being higher than those of substrate. Compaction and pressure solution have a negative impact on reservoir physical properties.

Use of aromatic plants and essential oils in the teaching of physics and chemistry to enhance motivation and sustainability awareness among primary education trainee teachers

This work faces the known problem of negative visión among prospective primary teachers regarding science teaching and learning. This is even more acute if gender is taken into account. To overcome this, the use of ethnobotany as a science of proximity is proposed. Specifically, an educational intervention is described that is based on a combination of active methodologies and the use of ethnobotany as a teaching tool for a subject with physics and chemistry contents. Ninety-two university-based primary education trainee teachers participated in the research. By means of questionnaires, information was collected regarding attitudes toward the subject and the use of ethnobotany as a teaching tool, evaluation of the proposal, sustainability awareness, and affective and emotional dimensions. The data indicated a great impact and acceptability. The results show a significant increase in motivation, an improvement in attitudes toward sustainable behavior and a favorable assessment of the proposed didactic tool. This hybrid methodology demonstrates, in the context used, effectiveness in improving the perception of science.

Addressing the elephant in the room: how erotic transference is identified and understood in therapy

ABSTRACT The central aim of the current study is to further the understanding of how therapists identify and understand erotic transference in therapy, and how they perceive it to influence the therapeutic processes and alliance. Answers were analyzed thematically using an open-coding analysis. A total of 116 therapists participated in the study reflecting on how erotic transference is experienced in the therapeutic setting. Data analysis yielded three main themes: (1) threat; (2) boundaries; and (3) growth. The threat theme included two subthemes: Threat to the therapeutic process and threat to the therapist’s professional-esteem. Growth also consisted of two subthemes: development of the therapist and opportunity for insight (into the inner world of the patient). The present study subscribes to the idea that erotic transference is a significant aspect of the therapeutic setting and, if addressed appropriately and more comprehensively, can have a great impact on the patient’s healing process.

Effects of transient, persistent, and resurgent sodium currents on excitability and spike regularity in vestibular ganglion neurons.

Vestibular afferent neurons occur as two populations with differences in spike timing regularity that are independent of rate. The more excitable regular afferents have lower current thresholds and sustained spiking responses to injected currents, while irregular afferent neurons have higher thresholds and transient responses. Differences in expression of low-voltage-activated potassium (K LV ) channels are emphasized in models of spiking regularity and excitability in these neurons, leaving open the potential contributions of the voltage-gated sodium (Na V ) channels responsible for the spike upstroke. We investigated the impact of different Na V current modes (transient, persistent, and resurgent) with whole-cell patch clamp experiments in mouse vestibular ganglion neurons (VGNs), the cultured and dissociated cell bodies of afferents. All VGNs had transient Na V current, many had a small persistent (non-inactivating) Na V current, and a few had resurgent current, which flows after the spike peak when Na V channels that were blocked are unblocked. Na V 1.6 channels conducted most or all of each Na V current mode, and a Na V 1.6-selective blocker decreased spike rate and altered spike waveforms in both sustained and transient VGNs. A Na V channel agonist enhanced persistent current and increased spike rate and regularity. We hypothesized that persistent and resurgent currents have different effects on sustained (regular) VGNs vs. transient (irregular) VGNs. Lacking blockers specific for the different current modes, we used modeling to isolate their effects on spiking of simulated transient and sustained VGNs, driven by simulated current steps and noisy trains of simulated EPSCs. In all simulated neurons, increasing transient Na V current increased spike rate and rate-independent regularity. In simulated sustained VGNs, adding persistent current increased both rate and rate-independent regularity, while adding resurgent current had limited impact. In transient VGNs, adding persistent current had little impact, while adding resurgent current increased both rate and rate-independent irregularity by enhancing sensitivity to synaptic noise. These experiments show that the small Na V current modes may enhance the differentiation of afferent populations, with persistent currents selectively making regular afferents more regular and resurgent currents selectively making irregular afferents less regular.

Are haloclines distributional barriers in anchialine ecosystems? Physiological response of cave shrimps to salinity.

Anchialine systems are coastal groundwater habitats around the world which host a unique community of cave adapted species (stygobionts). Such communities are expected to be separated by haloclines into either fresh or saline groundwater communities, hence climate changes (e.g., eustatic sea level shifts) and anthropic driven changes (e.g., salinization) may have a great impact on these stygobiont communities. Here we used cave-restricted species of Typhlatya from the Yucatan Peninsula as models to identify physiological capacities that enable the different species to thrive in marine groundwater (T. dzilamensis) or fresh groundwater (T. mitchelli and T. pearsei), and test if their distribution is limited by their salinity tolerance capacity. We used behavior, metabolic rates, indicators of the antioxidant system and cellular damage, and lactate content to evaluate the response of individuals to acute changes in salinity, as a recreation of crossing a halocline in the anchialine systems of the Yucatan Peninsula. Our results show that despite being sister species, some are restricted to the freshwater portion of the groundwater, while others appear to be euryhaline.

Are Cities Doing the Same? Local Policies on Immigrant Integration in Catalonia Since the Great Recession

AbstractThis article analyzes the extent to which the councils of five Catalan cities have modified their integration policies. The structural transformations of contemporary societies have had a great impact on city councils and local integration policies, especially from the point of view of planning and policy orientation. The article studies the policies developed in five Catalan cities in the last four mandates, specifically between 2007 and 2023, based on in-depth interviews and analysis of political and technical documentation. Although the strategies used in the five cities analyzed are not identical, the results show that during these years there has been a tendency to limit the approval of plans for the integration of immigrants, although this does not mean that the councils do not have explicit political priorities and objectives. The cities also tend to speak less specifically about integration and, on the contrary, resort to two different orientations: some councils design and implement policies related to security, mediation, and community work in neighborhoods, while others tend to broaden the focus of their policies, opting for more holistic approaches focused on multiple forms of diversity, intersectionality, and anti-racism.

There are a few contextual historical factors which have had a great impact on the country's educational priorities in relation to foreign languages. Nowadays learning an L2 (usually English) is compulsory from the first grade of primary education. Current methodological trends in Poland are similar to general tendencies in Europe and contemporary research on foreign language education draws from different fields including sociolinguistics, neurolinguistics, psycholinguistics, computer-oriented studies, and others.

Spatial Analysis of Aquatic Ecological Health under Future Climate Change Using Extreme Gradient Boosting Tree (XGBoost) and SWAT

Climate change not only affects the water resource system but also has a great impact on the aquatic ecosystem, which is complexly linked to various organic and inorganic matter. It is difficult to simulate the current aquatic ecosystem and predict the future system due to the immensity and complexity of aquatic ecosystems; however, a spatial analysis of future aquatic ecological health is necessary if we are to adapt and take action against future climate change. In this study, we evaluated the aquatic ecological health of the Han River basin under the future climate change RCP4.5 and RCP8.5 scenarios using three indices: fish assessment index (FAI), trophic diatom index (TDI), and benthic macroinvertebrate index (BMI). For this, we developed the SWAT-XGBoost linkage algorithm, and the algorithm accuracy for the FAI, TDI, and BMI was 89.3~95.2%. In the case of the FAI and BMI assessment of aquatic ecological health, the upstream Han River was classified as a hot spot. In the case of the TDI, the downstream area of the Han River was classified as a cold spot. However, as the current TDI downstream was classified as grades D and E, continuous management is needed.

Experience of Diagnosis and Initiation of Renal Replacement Therapy in Women with Chronic Kidney Disease.

Chronic kidney disease (CKD) has considerable effects on the quality of life of female patients. Receiving the diagnosis and beginning renal replacement therapy (RRT) has a great personal impact on patients. The purpose of this study was to describe the experience of female patients with CKD at an ambulatory dialysis unit regarding diagnosis, life changes, and initiation of RRT. A qualitative exploratory study was conducted based on a social contructivism framework. Participants were recruited using purposeful sampling. In total, 18 women who received treatment for CKD with RRT were included. The women were attending the Ambulatory Dialysis Unit at a hospital belonging to the public health system of Madrid (Spain). Unstructured and semi-structured in-depth interviews, researchers' field notes, and women's personal letters were used. A systematic text condensation analysis was performed. The criteria used to control trustworthiness were credibility, transferability, dependability, and confirmability. Two themes emerged from the data: (a) A turning point in their lives, and (b) The emotional journey of beginning RRT. The diagnosis of CKD and the beginning of treatment implies changing routines and adapting to a new life with CKD. The first dialysis and puncture of the arteriovenous fistula is a major experience. Support from other CKD patients with more experience is perceived as a necessity and a tool to share their experiences and resolve doubts among peers. The diagnosis and initiation of RRT leads to numerous changes in the lives of women with CKD, which may influence the acceptance of treatment.
