Published: September 2024

Background

Fibromyalgia (FM) is a complex rheumatic disorder characterized by chronic nociplastic pain and central sensitization. Psychopathological conditions can influence FM symptoms, which worsen their condition. However, not all patients with FM have psychopathological disorders, indicating a heterogeneous population.

Objective

To investigate the psychopathological profile and personality disorders in patients with FM and its relationship impact on this disease.

Methods

An observational and cross-sectional comparative study was conducted with a sample of 90 women, mean age 48.7 years (SD = 8.12), from Hospital del Mar, Barcelona. The Personality Assessment Inventory (PAI) and the Fibromyalgia Impact Questionnaire (FIQ) were used for assessment.

Results

FM patients predominantly exhibited psychopathological profiles resembling affective disorders (37.7%) and Cluster C personality disorders (58.8%). The severity of FM’s impact was related to affective disorder symptoms, hypervigilance, derealization, somatization, and Cluster B personality disorder (emotional instability). Different rheumatic symptoms correlated with specific psychopathological patterns. Increased somatic symptoms on the FIQ were related to an unstable and dependent personality, while heightened emotional symptoms on the FIQ were associated with avoidance, borderline traits, and passive-aggressive reactions.

Conclusion

Recognizing psychopathological aspects is crucial for managing FM. The PAI is a valuable tool for establishing its psychopathological multidimensional profile, which predominantly shows an affective spectrum conditions and comorbid Cluster C personality disorder, exacerbating the disease’s impact.
Depression in youths with early life adversity: a systematic review and meta-analysis
Authors: Yu Zengyan , Cao Yunhua , Shang Tinghuizi , Li Ping
Published: September 2024

Background

Globally, early-life adversity (ELA) is linked to an increased risk of developing depression in adulthood; however, only a few studies have examined the specific effects of various types of ELA on depression in children and adolescents. This meta-analysis explores the association between the subtypes of ELA and the risk for youth-onset depression.

Methods

We searched three electronic databases for reporting types of ELA, namely, emotional abuse, physical abuse, sexual abuse, emotional neglect, physical neglect, family conflict/violence, divorce, low socioeconomic status, and left-behind experience, associated with depression before the age of 18 years. Our meta-analysis utilized the odds ratio (OR) and relied on a random effects model. Large heterogeneous effects were detected. Some factors moderated the association between ELA and depression in youths. The homogeneity of variance test and meta-regression analysis were used to detect these relationships.

Results

A total of 87 studies with 213,006 participants were ultimately identified via several strategies in this meta-analysis. Individuals who experienced ELA were more likely to develop depression before the age of 18 years old than those without a history of ELA (OR=2.14; 95% CI [1.93, 2.37]). The results of the subgroup analysis revealed a strong association between ELA and depression in youth, both in terms of specific types and dimensions. Specifically, emotional abuse (OR = 4.25, 95% CI [3.04, 5.94]) was more strongly related to depression in children and adolescents than other forms of ELA were. For both dimensions, threat (OR = 2.60, 95% CI [2.23, 3.02]) was more closely related to depression than deprivation was (OR = 1.76, 95% CI [1.55, 1.99]).

Conclusion

This meta-analysis revealed that the adverse effects of a broader consideration of ELA on the risk of youth-onset depression vary according to the subtypes of ELA.

Optimal dose and type of exercise to improve cognitive function in patients with mild cognitive impairment: a systematic review and network meta-analysis of RCTs
Authors: Yu Yingying , Wang Junjie , Xu Jian
Published: September 2024

Background

Mild cognitive impairment (MCI) represents a prodromal stage of dementia, characterized by cognitive decline exceeding that expected with normal aging. Exercise interventions have emerged as a promising approach to counter functional decline and enhance cognitive function in the elderly MCI population. However, the optimal exercise modalities and dosage (dose-response relationship) are understudied.

Objective

It aims to determine the most effective exercise modality for MCI patients by optimizing the dose-response relationship to ensure sufficient intensity to induce positive neurological adaptations.

Methods

A systematic search of electronic databases, including PubMed, Embase, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials was conducted from inception to April 15, 2024. Studies evaluating the efficacy of exercise interventions in MCI participants were included. Primary outcomes of interest are global cognition and executive function. Random-effects models will be utilized for both pairwise and network meta-analysis.

Results

Following the application of specific inclusion and exclusion criteria, a total of 42 articles, encompassing 2832 participants, were chosen for inclusion in a network meta-analysis. The findings revealed that multi-component exercise demonstrated superior efficacy in mitigating the deterioration of global cognition, as evidenced by standard mean differences (SMDs) of 1.09 (95% CI: 0.68 to 1.51) compared to passive controls. Additionally, multi-component exercise exhibited a significant impact on executive function, with SMDs of 2.50 (95% CI: 0.88 to 4.12) when contrasted with passive controls. Our research has demonstrated that sessions lasting 30 minutes, occurring 3-4 times per week, with interventions lasting 12-24 weeks and an intensity of 60-85% of maximum heart rate, yield higher effect sizes in improving global cognition. However, sessions lasting 30-61 minutes, with interventions lasting 25 weeks or longer, show greater effectiveness in enhancing executive function.

Conclusion

A network meta-analysis identified multi-component exercise as the most effective intervention for improving global cognitive and executive function in patients with mild cognitive impairment. Notably, moderate-intensity exercise performed at least three times weekly appears beneficial, with evidence suggesting shorter sessions and higher frequencies may optimize cognitive outcomes.

Is thyroid dysfunction a cause or a trigger of bipolar disorder? a case report
Authors: Yao Jiashu , Xu Jiating , Yan Rong , Ye Ruihuan , Shen Yuedi , Dai Ning , Chen Wei
Published: September 2024

Here we report on a case of a 40-year-old female patient who presented with hypomanic episode after hyperthyroidism and major depressive episode after hypothyroidism, which was initially misdiagnosed as bipolar disorder due to another medical condition, and was found to be a co-morbid bipolar disorder of hyperthyroidism after treatment and follow-up. The course of diagnosis and treatment in this case suggests a close temporal relationship does not necessarily mean that there is a causal relationship on a physiologic level. User’s Guide for the SCID-5-CV Structured Clinical Interview for DSM-5 Disorders elaborate that the diagnosis of “……due to another medical condition” is relatively rare, and co-morbidity between psychiatric disorders and somatic diseases is much more common. Therefore, the relationship between somatic diseases and psychiatric disorders requires careful study of symptom correlation and more time for observational follow-up. When in doubt, the examiner’s default assumption should be that the somatic disease is not the cause (i.e., the psychiatric disorder is primary).

Authors: Bayked Ewunetie Mekashaw , Yimer Ebrahim M. , Gelaw Tiruset , Mohammed Abdu Seid , Mekonen Nigusie Abebaw
Published: September 2024

Background

Despite global efforts, progress in reducing maternal malnutrition falls short of international goals, which is the same for Ethiopia, provided that studying dietary knowledge, attitude, and practice and their determinants is crucial to developing and implementing effective interventions, which this review tried to investigate in an Ethiopian context.

Methods

We searched on Scopus, HINARI, PubMed, and Google Scholar on January 3, 2024. We used the Joanna Briggs Institute’s (JBI’s) tools and the “preferred reporting items for systematic reviews and meta-analyses (PRISMA) 2020 statement” to evaluate bias and frame the review, respectively. The data were analyzed using Stata 17. Certainty was assessed using sensitivity and subgroup analyses and the Luis Furuya-Kanamori (LFK) index. The random effects model was used to determine the effect estimates with a p value less than 0.05 and a 95% CI.

Results

The pooled good dietary knowledge, favorable attitude, and good practice were 48.0% (95% CI: 39.0–57.0%), 47.0% (95% CI: 38.0–55.0%), and 34.0% (95% CI: 28.0–40.0%), respectively. Knowledge and attitude had bidirectional relationships and were affected by sociodemographic variables and gynecological issues. The dietary practice was influenced by urban residency (OR = 6.68, 95% CI: 2.49–10.87), food security (OR = 3.51, 95% CI: 1.02–5.99), knowledge (OR = 4.53, 95% CI: 3.22–5.74), nutrition information (OR = 3.07, 95% CI: 1.13–5.02), attitude (OR = 2.32, 95% CI: 1.34–3.30), family support (OR = 2.14, 95% CI: 1.43–2.85), perceived severity of malnutrition (OR = 2.07, 95% CI: 1.82–2.31), and positive perception of dietary benefit (OR = 2.19, 95% CI: 1.56–2.82).

Conclusion

The good dietary practice was lower than the knowledge and the favorable attitude toward it. It was influenced by sociodemographic variables, income and wealth, knowledge and information, attitudes and intentions, gynecological and illness experiences, family support and decision-making, and expectations of nutrition outcomes and habits. Sociodemographic and gynecological issues were also found to influence both dietary knowledge and attitude, which were also found to have bidirectional relationships.

Published: September 2024

Background

Homeless people are continuously facing adverse living conditions as poor access to basic nutrition, hygiene conditions and healthcare services, being at increased risk of severe infectious diseases as HIV and hepatitis as well as cardiovascular diseases and mental disorders. The characterization of homeless people’s health is fundamental to identify their health care needs. Considering that the aforementioned diseases are associated with chronic inflammatory processes, the main goal of this study was to characterize the inflammatory profile of a homeless population through quantification in saliva of a panel of inflammatory cytokines.

Methods

The inflammatory profile was assessed in 114 individuals residing in two temporary shelters located in Lisbon and that accepted to participated in the study. Inflammatory proteins were quantified using a Multiplex Immunoassay approach. Data analysis was performed using the GraphPad Prism software and statistical significance among the groups was assessed using the nonparametric Mann–Whitney test.

Results

Even though some protein levels might be masked by drug treatment, data analysis showed high levels of INF-ϒ, IL-10 and TNF-α in the infectious disease group, critical cytokines for the immune response against viruses and bacteria. Also, cytokines like IL-1β and IL-6 were detected at statistically significant levels in the cardiovascular disease group and all cytokines included in this study were quantified in the mental disorders group.

Conclusion

These findings may help the healthcare services in the evaluation of treatment efficacy and disease monitoring, and in the development of effective public healthcare strategies and policy interventions to improve quality of life of the homeless population.
Assessing the efficiency of China’s national fitness public services: a super-efficiency DEA-Malmquist–Tobit approach
Authors: Gao Xueting , Cao Li , Gu Qian
Published: September 2024

Introduction

As the Chinese government places an increasing emphasis on public fitness services, there has been a concomitant growth in public demand for greater fiscal expenditure in this area. However, in light of the constrained growth in government financial resources, it is of paramount importance to allocate these resources in a rational manner in order to effectively address the public’s fitness and health needs. This study aims to evaluate the efficiency of public expenditure on national fitness services across China, thereby providing valuable insights for policymakers to optimize resource allocation and improve service efficiency.

Methods

The study employs a super-efficiency Data Envelopment Analysis (DEA) model, in conjunction with the Malmquist Index and Tobit regression model, to assess the efficiency of fiscal spending on fitness services in 31 Chinese provinces from 2017 to 2020. The analysis employs both static and dynamic approaches to present an objective view of the development of public fitness service levels across different regions and to empirically identify the key factors influencing fiscal spending efficiency.

Results

The findings indicate substantial regional variations in the efficiency of fiscal expenditure on public fitness services. While some provinces demonstrate high efficiency in the use of public funds, others exhibit notable inefficiencies, particularly in areas with lower levels of economic development and population density. The findings underscore the existence of redundant expenditure and the varying effectiveness of resource utilization across provinces.

Discussion

The study recommends that future strategies prioritize the scientific planning of fiscal inputs into public fitness services, the precise optimization of expenditure structures, the exploration of collaborative supply mechanisms, the expansion of demand-driven feedback channels, the integration of technological innovations, and the acceleration of digitalization in public fitness services.

Published: September 2024

Introduction

Vaccination practice is a well-known individual protective measure for biological risk in healthcare. During the COVID-19 pandemic vaccine hesitancy has grown among healthcare workers (HCWs). The study aims to investigate how vaccine hesitancy influences the psychological burden experienced by healthcare workers.

Methods

This study aimed to explore attitudes of HCWs in acceptance or refusal of vaccinations related to the risk of psychological impairment (PI) and describe the associated occupational factors, during the seasonal flu/COVID-19 vaccination campaign of 2022–2023. 302 HCWs were enrolled in the study. A questionnaire was self-administered, including two scales on the risk of psychological impairment (Psychological Injury Risk Indicator, PIRI) and vaccine hesitancy (Adult Vaccine Hesitancy Scale, AVHS).

Results

PIRI scores revealed that 29.8% of participants were at risk of PI. Differences in sex, age, occupational seniority, professional category, and night shifts were found between HCWs at risk of PI and those not at risk. Females registered a four-fold higher risk than males (85.6% vs. 14.4%, χ2 = 4.450, p < 0.05). Nurses were the highest risk category, followed by physicians and technicians (54.4% vs. 30.0% vs. 12.2%, χ2 = 14.463, p < 0.001). 41.7% of participants received the flu vaccination, and 98.9% received the COVID-19 vaccine. HCWs were prone to being vaccinated to protect patients and family members. Conversely, vaccine refusal was attributed to the perception of flu vaccines as not beneficial and COVID-19 contagion at low risk. The latter was more frequently reported for HCWs at risk of PI (16.7% vs. 4.7%, χ2 = 11.882, p = 0.001). Finally, hesitant HCWs were at higher risk of psychological impairment than others.

Discussion

HCWs expressed vaccine acceptance considering their social role in the community as protectors. However, the underestimation of the risk of severity of COVID-19 was more relevant among HCWs at risk of PI than others. Psychological aspects need to be considered by healthcare providers when fighting vaccine hesitancy.

Published: September 2024

Introduction

The aim of this study was to evaluate the impact of the thoracic robotic approach in a high-volume center regarding procedures and clinical outcomes after 1,000 procedures.

Methods

In a single-center subset of the Epithor® database, a prospective cohort database of French thoracic surgery, we analyzed procedural characteristics and clinical outcomes from February 2014 to April 2023. A surgical technique for lung surgery was conducted with a four-arm closed chest with the port access approach and vascular sewing and knotting were preferred over stapling. Statistical analysis was performed using the Chi-2 test for discontinuous variables and the Mann–Whitney–Wilcoxon test for continuous variables. Tests were considered significant for a p-value <0.05.

Results

Robotic thoracic surgery was used in anatomical lung resection in 85% of the cases. Over the study period, 1,067 patients underwent robotic surgery, of which 509 had lobectomies and 391 segmentectomies. In the segmentectomy group vs. lobectomy group we observed a shorter length of stay (9 ± 7 vs. 7 ± 5.6 days, p < 0.001), a shorter surgery time (99 ± 24 vs. 116 ± 38 min, p < 0.001) a lower conversion rate (n = 2 vs. n = 17, p = 0.004), and a lower complication rate (28% vs. 40%, p = 0.009, mainly Clavien–Dindo II, 18% and 28%, respectively). For cancer treatment surgery, we found more previous cancer in the segmentectomy group (48% vs. 26%, p < 0.001). We also observed a progressive change of lobectomy vs. segmentectomy from 80%/20% to 30%/70% over the 9 years.

Discussion

A robotic platform is an appropriate tool to perform anatomical lung resection and especially to develop a safe and systematic approach to lung-sparing sub-lobar resection.

Published: September 2024

In response to prominent issues in existing wine grape cultivation, such as complex power machinery integration, inconvenient connection operations, and low efficiency of unilateral walking operations, a gantry track-mounted multifunctional operations platform for wine grapes was developed. The platform spans across grape trellises, enabling dual-sided operations in a single pass. Considering the high stability requirements for wine grape operations, the track walking device and hitch-lifting mechanism were developed. To accommodate the varying speed requirements of different operational stages, engine power and gearbox gear selection were calculated and selected. Structural strength analysis, steering performance analysis, and overall stability analysis of the machine were conducted. Field test results indicate a maximum operating speed of 3.85 km/h and a minimum turning radius of 3.95 m, meeting the needs of field operations. The maximum climbing angle is no more than 18°, and the machine experiences no lateral sliding or tipping when the maximum lateral tilt angle is below 28°. The hitch-lifting mechanism showed an average settlement of 1.58 mm when lifting to different heights, with a stability rate of 99.7%. This study demonstrates that the developed multifunctional operations platform can meet the field operation requirements of wine grape cultivation.

Published: September 2024

In order to explore the potential of biochar produced from poultry manure for sustainable waste utilization, carbon sequestration, and agricultural development, this study examines the impact of biochar on the growth of the halophyte plant Salicornia herbacea L., or glasswort. Because of their properties of morphological and chemical properties, biochar has been gaining interest as a potential solution to addressing both the concerns of climate change and unsustainable agriculture. In this study, the characteristics of biochar were analyzed and its impact on plant growth by stem length was measured over 15 weeks. Poultry-based biochar was created through pyrolysis at the temperatures of 400, 500, and 700 °C. Various amounts of biochar produced from pyrolysis at 500 °C were put to soil. However, the average surface area and average pore size values of poultry manure biochar produced from temperatures 400, 500, and 700 °C were similar enough to be negligible. The biochar sample produced from the pyrolysis temperature of 500 °C had an average pore size of 17.18 nm and a surface area of 18.06 m2/g. From weeks 4 to 15, all groups exhibited increased stem length, with the most significant differences observed between the biochar 0% (control) and biochar 10% groups, with biochar 0% and biochar 10% denoting 0% and 10% weight concentrations of biochar, respectively. While biochar 5% and biochar 7% groups showed minimal differences in stem length, biochar 10% demonstrated a significant increase, suggesting an optimal biochar percentage for enhancing plant growth. Carbon credit estimations have suggested that 1 ton of poultry manure biochar produced from pyrolysis at 500 C° equates to an estimate of 0.5248 ± 0.0580 carbon credits, the highest of all three biochar samples. All three samples (biochar produced from 400, 500, and 700 °C pyrolysis temperatures) had increased heavy metal contents and a wider range of functional groups. The findings indicate that biochar can effectively improve soil health and plant performance overall, with biochar 10% showing the most significant impact on Salicornia growth.

Nuclear magnetic resonance (NMR) is a technique used for many years by chemists for elucidation of molecular structure. Technological progress over the years has enabled this technique, making it easier to use. Thus, the LF-NMR (low-field NMR) was introduced as a side technique, characterized by low management costs and shorter analysis time than its main counterpart. The application of 1H LF-NMR for the quantification of ethyl alcohol in different alcoholic matrices is herein described, comparing the results obtained with this technique with those determined by a reference gas chromatographic method.
In Vivo Antioxidant Activity of Common Dietary Flavonoids: Insights from the Yeast Model Saccharomyces cerevisiae
Authors: Assalve Graziana , Lunetti Paola , Zara Vincenzo , Ferramosca Alessandra
Published: September 2024

Background: Oxidative stress, associated with diseases and aging, underscores the therapeutic potential of natural antioxidants. Flavonoids, known for scavenging free radicals and modulating cell signaling, offer significant health benefits and contribute to longevity. To explore their in vivo effects, we investigated the antioxidant activity of quercetin, apigenin, luteolin, naringenin, and genistein, using Saccharomyces cerevisiae as a model organism. Methods: We performed viability assays to evaluate the effects of these compounds on cell growth, both in the presence and absence of H2O2. Additional assays, including spot assays, drug drop tests, and colony-forming unit assays, were also conducted. Results: Viability assays indicated that the tested compounds are non-toxic. H2O2 reduced yeast viability, but flavonoid-treated cells showed increased resistance, confirming their protective effect. Polyphenols scavenged intracellular reactive oxygen species (ROS) and protected cells from oxidative damage. Investigations into defense systems revealed that H2O2 induced catalase activity and oxidized glutathione accumulation, both of which were reduced by polyphenol treatment. Conclusions: The tested natural compounds enhance cell viability and reduce oxidative damage by scavenging ROS and modulating antioxidant defenses. These results suggest their potential as supplements and pave the way for further research.
Adaptive Channel-Enhanced Graph Convolution for Skeleton-Based Human Action Recognition

Published: September 2024

Obtaining discriminative joint features is crucial for skeleton-based human action recognition. Current models mainly focus on the research of skeleton topology encoding. However, their predefined topology is the same and fixed for all action samples, making it challenging to obtain discriminative joint features. Although some studies have considered the complex non-natural connection relationships between joints, the existing methods cannot fully capture this complexity by using high-order adjacency matrices or adding trainable parameters and instead increase the computation parameters. Therefore, this study constructs a novel adaptive channel-enhanced graph convolution (ACE-GCN) model for human action recognition. The model generates similar and affinity attention maps by encoding channel attention in the input features. These maps are complementarily applied to the input feature map and graph topology, which can realize the refinement of joint features and construct an adaptive and non-shared channel-based adjacency matrix. This method of constructing the adjacency matrix improves the model’s capacity to capture intricate non-natural connections between joints, prevents the accumulation of unnecessary information, and minimizes the number of computational parameters. In addition, integrating the Edgeconv module into a multi-branch aggregation improves the model’s ability to aggregate different scale and temporal features. Ultimately, comprehensive experiments were carried out on NTU-RGB+D 60 and NTU-RGB+D 120, which are two substantial datasets. On the NTU RGB+D 60 dataset, the accuracy of human action recognition was 92% (X-Sub) and 96.3% (X-View). The model achieved an accuracy of 96.6% on the NW-UCLA dataset. The experimental results confirm that the ACE-GCN exhibits superior recognition accuracy and lower computing complexity compared to current methodologies.

Authors: Li Yongxin , Zhang Zhimin , Dong Jinyu , Wang Bobo , Wang Chuang
Published: September 2024

Based on the Xiaolangdi North Bank Irrigation Area Project, this study combines numerical simulation and BP neural network methods to investigate the sensitivity of tunnel soil and its parameter inversion under continuous heavy rainfall. The research results indicate that changes in water-level and soil strength parameters have a significant impact on the deformation of tunnel surrounding rock. By comparing the sensitivity factors of different parameters, the main parameter sensitivities affecting the displacement of tunnel surrounding rock were determined to be water level, internal friction angle, and cohesion. The mechanical characteristics of the tunnel construction process were analyzed using finite difference method numerical analysis software FLAC3D, and the results were used as a sample dataset for inversion analysis. Through neural network inverse analysis based on orthogonal design method, the cohesion and internal friction angle of loess layer ④, loess layer ④-1, and loess layer ⑤ were determined, and the data of groundwater level elevation were obtained. Field applications proved the effectiveness and rationality of this method.

Authors: Comi Antonio , Idone Ippolita
Published: September 2024

The integration of electric vehicles (EVs) into the electricity grid through vehicle-to-grid (V2G) technology represents a promising opportunity to improve energy efficiency and stabilize grid operations in the context of building sustainable cities. This paper provides a systematic review of the literature to assess the status of the research and identify the road ahead. Using bibliometric analysis and systematic assessment, the critical factors that influence the charging behavior of electric vehicles, the adoption of V2G, and the effective use of EVs as dynamic energy resources are identified. The focus is particularly on the ecological transitions toward sustainability, travel characteristics, technical specifications, requirements, and barriers in real use, and the behavioral and psychological aspects of stakeholders. The results lay the foundation for accurate forecasts and the strategic implementation of V2G technology to support the needs of the electric grid. They emphasize the importance of considering the psychological and behavioral aspects of users in the design of V2G strategies and define the key factors to predict the demand for electric vehicle charging. Furthermore, they highlight the main barriers to V2G adoption, which are primarily related to concerns about battery degradation and economic issues. Privacy and security concerns, due to data sharing with electric vehicle aggregators, also limit the adoption of V2G. Addressing these challenges is essential for the successful integration of electric vehicles into the grid.

Published: September 2024

Gun violence is a global problem that affects communities and individuals, posing challenges to safety and well-being. The use of autonomous weapons detection systems could significantly improve security worldwide. Despite notable progress in the field of weapons detection closed-circuit television-based systems, several challenges persist, including real-time detection, improved accuracy in detecting small objects, and reducing false positives. This paper, based on our extensive experience in this field and successful private company contracts, presents a detection scheme comprising two modules that enhance the performance of a renowned detector. These modules not only augment the detector’s performance but also have a low negative impact on the inference time. Additionally, a scale-matching technique is utilised to enhance the detection of weapons with a small aspect ratio. The experimental results demonstrate that the scale-matching method enhances the detection of small objects, with an improvement of +13.23 in average precision compared to the non-use of this method. Furthermore, the proposed detection scheme effectively reduces the number of false positives (a 71% reduction in the total number of false positives) of the baseline model, while maintaining a low inference time (34 frames per second on an NVIDIA GeForce RTX-3060 card with a resolution of 720 pixels) in comparison to the baseline model (47 frames per second).

Authors: Moreno-Rosa Guillermo , López-Gutiérrez Carlos Javier , Castro-Sánchez Manuel
Published: September 2024

(1) Background: The psychological benefits of cycling have been identified such as the maintenance of low-stress levels. However, no studies have been found addressing the benefits of cycling on variables such as emotional intelligence (EI) and motivational climate (MC), which are important for holistic development in children. This study aimed to investigate the interrelationships between MC, EI, and cycling habits in schoolchildren. (2) Methods: A descriptive, comparative, cross-sectional study was conducted in a sample of 347 Spanish schoolchildren (46.4% boys; 53.6% girls; Mage = 10.55, S.D. = 0.97). A sociodemographic questionnaire, the Trait Meta-Mood Scale (TMMS-24), and the Perceived Motivational Climate in Sport Questionnaire (PMCSQ-2) were applied for data collection. (3) Results: Boys use bicycles more frequently than girls; task-oriented motivational climate (TC) is observed in girls and schoolchildren with moderate cycling habits; ego-involving motivational climate (EC) prevails in boys and students who cycle more than four times per week; no statistical association was found between EI and cycling use habits; and EI and its dimensions correlate with TC and some categories of EC. (4) Conclusions: Moderate cycling habits are linked to a task-oriented MC and have slightly higher scores on general EI and its dimensions.
Quantitative Assessment of Rock Burst Risk in Roadway Tunneling Considering Variation of Coal Mass Parameters
Authors: Yang Yu , Li Ning
Published: September 2024

To investigate the influence of varied mechanical parameters of coal mass on rock burst occurrence during deep roadway tunneling, the surrounding coal and rock mass of a deep roadway were taken as the research objects. A geometric model of roadway tunneling was developed using 3DEC numerical simulation software, and the failure characteristics of the coal mass in the roadway side were analyzed based on the rock burst mechanism and stress difference gradient theory for deep mining. The risk of rock burst during roadway tunneling was quantitatively assessed using the change rate of the stress difference gradient (Dgc), thereby elucidating the burst failure patterns of the deep roadway under the influence of varied mechanical parameters. The findings indicate that the coal mass in the roadway side zone is more prone to burst failure due to stress disturbances during deep excavation compared to the coal and rock mass in the roof and floor zones, and that the released kinetic energy and the risk of burst failure are positively correlated with the magnitude of the ground stress. The variation of the mechanical properties of coal mass has a significant effect on the rock burst risk during roadway tunneling. The variation of both internal friction angle and cohesion significantly affects rock burst, with cohesion exerting a greater influence. Conversely, the elastic modulus does not significantly impact the risk. The tendency of bursting in the coal mass is positively correlated with the coefficient of variation (COV) in cohesion and negatively correlated with the COV in internal friction angle. These research findings offer valuable insights for the quantitative assessment of rock burst risk during roadway tunneling.

The Henan area of the middle and lower reaches of the Yellow River is situated within the third sedimentary loess area, positioned as the southeasternmost segment within the transitional belt connecting the Loess Plateau with the North China Plain. Addressing concerns related to loess collapse, landslides, and subgrade settlement across various regions attributable to the collapsible nature of Malan loess in western Henan, this study undertook collapsibility testing of undisturbed Malan loess in the province. The different mechanisms of loess collapsibility in different regions were explained from the microstructure by using the indoor immersion-compression test double-line method, scanning electron microscope (SEM), and particles and cracks analysis system (PCAS). The relationship between quantitative factors of microstructure and collapsibility of loess was analyzed by linear regression analysis. The findings indicate that under identical overburden pressure and immersion conditions, the collapsibility of Malan loess in western Henan diminishes progressively from west to east. Microstructural tests were conducted on various loess specimens using scanning electron microscopy, revealing that the distribution of loess particles is notably concentrated in the Xingyang and Gongyi areas, leading to a reduction in pore area compared to the Shanzhou and Mianchi areas. While the Mianchi and Shanzhou areas exhibit a loose arrangement of loess particles, those in Xingyang and Gongyi are comparatively denser. Analysis of microstructural images through the particles and cracks analysis system elucidated that the pore arrangement in the Gongyi and Xingyang areas is more stable than in the Mianchi and Shanzhou areas. Additionally, there is a gradual concentration in particle distribution, accompanied by an increase in agglomeration degree. According to the analysis and comparison of microstructure and quantitative parameters of four groups of loess samples before and after collapsibility, it is revealed that the change mechanism underlying loess collapsibility in various regions of western Henan primarily stems from the external factors influencing the microstructural alterations within the loess. The microstructural determinants contributing to collapsibility changes in different regions encompass three principal aspects: Firstly, modifications in the grain morphology of the Malan loess skeleton in western Henan are notable. Secondly, variations in the internal pore characteristics of loess microstructure are observed. Thirdly, disparities exist in the interconnections between soil particles. The findings of this research hold significant worth for improving construction safety and geological hazard prevention within the Loess region of western Henan.

A faulty voltage measurement can lead to the overcharging of a Li-Ion cell, resulting in gas formation and heating inside the cell, which can trigger thermal runaway. To mitigate this risk, cylindrical cells are equipped with a Current Interrupt Device (CID), which functions as a pressure relief valve, disconnecting the electrical circuit within the cell when internal pressure rises. However, this disconnection causes the cell to suddenly become highly resistant, posing a significant issue in series-connected cells. In such configurations, a portion or even the entire system voltage may drop across the disconnected cell, substantially increasing the likelihood of an electric arc. This arc could ignite any escaping flammable gases, leading to catastrophic failures. In a series of tests conducted on three different cell chemistries—NMC (Nickel Manganese Cobalt), NCA (Nickel Cobalt Aluminum), and LFP (Lithium Iron Phosphate)—it was found that the safe operation of the CID cannot be guaranteed for system voltages exceeding 120 V. Although comparative tests at double the nominal cell voltage did not exhibit the same behavior, these findings suggest that current safety standards, which recommend testing at double the nominal voltage, may not adequately address the risks involved. The tests further revealed that series connections of cells with CIDs are inherently dangerous, as, in the worst-case scenario, the entire system voltage can be concentrated across a single cell, leading to potential system failure.
Advanced Multichannel Lighting Control Systems in Heritage Environments: Case Study of the Cathedral of Seville

The appropriate preservation and color rendering of paintings and art pieces are a pending subject in architectural heritage, since, in most of the cases, lighting systems are not really focused on the conservation and suitable perception of these heritage resources, due to the limitations of standard LED lamps and lighting configurations. In this context, a multichannel luminaire system is proposed in the case study of the Cathedral of Seville, providing a variable and rich spectral distribution, which allows an excellent color perception linked to the daylight conditions, while the short-wavelength light is minimized in order to reduce photodegradation. Two scenarios are addressed: Museum of the Cathedral and Evangelist Chapel. The multichannel luminaire system is tested by means of subjective surveys and objective procedures (Farnswoth-Munsell and Natural Color System tests). The results show that the proposed spectral distribution of the multichannel system provides a better color discrimination in comparison with typical lighting systems, as well as a better preservation, defining a suitable lighting technology for architectural heritage. The novelty of this study lies in the multi-parameter approach, taking care of color rendering while photodegradation is minimized.

The red spider mite, Tetranychus macfarlanei, is a serious pest of many cultivated crops in Bangladesh and other East-Asian and South-East Asian countries, in the Afrotropical, Oriental, and Palearctic regions. Sublethal concentration of pesticides, such as LC15 and LC30 (the concentrations that result in 15 and 30 percent lethality, respectively) impact reproduction, behavior, development, and physiology. This study assessed the effects of different concentrations of spirotetramat, an insecticide that disrupts lipid production, on the biological traits of T. macfarlanei. The LC15, LC30, LC50, and LC90 values were 2.16, 6.57, 20.54, and 332.81 mg·L−1, respectively. Sublethal concentrations (LC15 and LC30) slightly reduced female fecundity but did not significantly affect development duration, pre-oviposition, oviposition period, or longevity compared to the untreated control group. Life table parameters differed between the treated and control groups, with significant reductions in the intrinsic rate of increase (r), the net reproductive rate (R0), and the finite rate of increase (λ) for LC15 and LC30. LC15 and LC30 had negative effects on the intrinsic rate of increase for females. This study demonstrated that lower lethal concentrations of spirotetramat compromised survivability and negatively impacted the life-table parameters of subsequent generations of T. macfarlanei. These findings highlight the importance of sublethal effects in pest control, offering valuable insights for developing more effective and sustainable integrated pest management strategies.

Published: September 2024

Sălăgean differential operator Dκ plays an important role in the geometric function theory, where many studies are using this operator to introduce new subclasses of analytic functions defined in the open unit disk. Studies of Sălăgean differential operator Dκ in connection with Stirling numbers are relatively new. In this paper, the differential operator Dκ involving Stirling numbers is considered. A new sufficient condition involving Stirling numbers for the series Υθs(ϰ) written with the Pascal distribution are discussed for the subclass Tκ(ϵ,♭). Also, we provide a sufficient condition for the inclusion relation IθsRϖ(E,D)⊂Tκ(ϵ,♭). Further, we consider the properties of an integral operator related to Pascal distribution series. New special cases as a consequences of the main results are also obtained.
Secondary Envelopment of Human Cytomegalovirus Is a Fast Process Utilizing the Endocytic Compartment as a Major Membrane Source

Published: September 2024

Secondary envelopment of the human cytomegalovirus (HCMV) is a critical but not well-understood process that takes place at the cytoplasmic viral assembly complex (cVAC) where nucleocapsids acquire their envelope by budding into cellular membranes containing viral glycoproteins. Previous studies presented controversial results regarding the composition of the viral envelope, suggesting trans-Golgi and endosomal origins, as well as intersections with the exosomal and endocytic pathways. Here, we investigated the role of endocytic membranes for the secondary envelopment of HCMV by using wheat germ agglutinin (WGA) pulse labeling to label glycoproteins at the plasma membrane and to follow their trafficking during HCMV infection by light microscopy and transmission electron microscopy (TEM). WGA labeled different membrane compartments within the cVAC, including early endosomes, multivesicular bodies, trans-Golgi, and recycling endosomes. Furthermore, TEM analysis showed that almost 90% of capsids undergoing secondary envelopment and 50% of enveloped capsids were WGA-positive within 90 min. Our data reveal extensive remodeling of the endocytic compartment in the late stage of HCMV infection, where the endocytic compartment provides an optimized environment for virion morphogenesis and serves as the primary membrane source for secondary envelopment. Furthermore, we show that secondary envelopment is a rapid process in which endocytosed membranes are transported from the plasma membrane to the cVAC within minutes to be utilized by capsids for envelopment.
