Charging stations and electric vehicle (EV) charging networks signify a significant advancement in technology as a frontier application of the Social Internet of Things (SIoT), presenting both challenges and opportunities for current 6G wireless networks. One primary challenge in this integration is limited wireless network resources, particularly when serving a large number of users within distributed EV charging networks in the SIoT. Factors such as congestion during EV travel, varying EV user preferences, and uncertainties in decision-making regarding charging station resources significantly impact system operation and network resource allocation. To address these challenges, this paper develops a novel framework harnessing the potential of emerging technologies, specifically reconfigurable intelligent surfaces (RISs) and causal-structure-enhanced asynchronous advantage actor–critic (A3C) reinforcement learning techniques. This framework aims to optimize resource allocation, thereby enhancing communication support within EV charging networks. Through the integration of RIS technology, which enables control over electromagnetic waves, and the application of causal reinforcement learning algorithms, the framework dynamically adjusts resource allocation strategies to accommodate evolving conditions in EV charging networks. An essential aspect of this framework is its ability to simultaneously meet real-world social requirements, such as ensuring efficient utilization of network resources. Numerical simulation results validate the effectiveness and adaptability of this approach in improving wireless network efficiency and enhancing user experience within the SIoT context. Through these simulations, it becomes evident that the developed framework offers promising solutions to the challenges posed by integrating the SIoT with EV charging networks.

The Integration of Dual Evaluation and Minimum Spanning Tree Clustering to Support Decision-Making in Territorial Spatial Planning

Spatial planning, a policy instrument for creating sustainable environments that meet the needs of the current and future generations, has been implemented extensively worldwide. However, it is difficult for urban planners to thoroughly determine the spatial value of a territory and make informed decisions regarding the efficient utilization of regional resources in the real world. This study proposes a novel methodological framework for spatial pattern optimization that can guide future land use by integrating Minimum Spanning Tree (MST) clustering with a comprehensive evaluation system (dual evaluation). Furthermore, the validity of this framework is demonstrated through a case study of territorial spatial planning in Deyang, China. The findings indicate that (1) the methodological framework presented in this study offers valuable guidance for the spatial arrangement of territorial resources, especially in practical projects; and (2) the combination of dual evaluation and MST clustering can facilitate automatic regionalization to identify spatial clusters exhibiting functional similarity in terms of land use. By focusing on methodological advancements, this study concludes that the integration of dual evaluation (DE) and MST clustering not only simplifies the identification of optimal land-use patterns but also promotes a more systematic and efficient approach to support spatial planning.

Lupine-induced Crooked Calf Syndrome (CCS): Mitigation through intermittent grazing management of cattle

Abstract Lupines are responsible for a condition in cattle referred to as “crooked calf syndrome” (CCS) that occurs when pregnant cattle graze teratogenic lupines. A proposed management strategy to limit these types of birth defects includes utilizing an intermittent grazing schedule to allow short durations of grazing lupine-infested areas interrupted by movement to a lupine-free pasture. The objective of this study was to determine if an intermittent schedule of ten continuous days on lupine treatment followed by five days off treatment would be sufficient to decrease, or prevent, the incidence of lupine-induced malformations. Continuous dosing of the teratogenic lupine (Lupinus leucophyllus) to pregnant cows for 30 days during the most susceptible stage of pregnancy (gestation days 40-70) resulted in severe skeletal birth defects in their calves. However, intermittent dosing of the teratogenic lupine demonstrated that interrupted intake of lupine reduced the severity, or eliminated, permanent skeletal malformations in calves born to cows dosed lupine. Toxicokinetic and ultrasound data demonstrated a clear inverse correlation between serum anagyrine (the primary teratogenic alkaloid in some lupines) concentrations in the dam and fetal movement. In the intermittent group, fetal movement quickly returned to normal after lupine feeding stopped and remained normal until lupine treatment resumed. Therefore, interrupting lupine intake for at least five days through an intermittent grazing program could reduce the severity of the CCS. Furthermore, this method would allow ranchers to move cattle back into lupine pastures after a brief interruption, which would allow for more efficient utilization of forage resources.

Rational load balancing in collaborated cloud computing environments *

Abstract Optimum efficiency and fault tolerance are the most demanding and challenging issues in the domain of performance and reliability management in cloud computing environments. Optimized resource utilization is a key aspect for yielding efficiency in cloud platforms. Workload balancing through resource sharing is one of the key solutions for attaining performance in cloud environments. In addition, multiple cloud environments join hands to offer performance and fault tolerance through resource sharing. We provide a better and cloud-instances’ priority-based efficient load balancing method for collaborative cloud platforms. The recommended efficient load balancing method shortens the waiting timespan and overcomes the starvation problem of low priority instances in intercloud environments. A functional prototype of the recommended load balancing method was deployed on a physical cloud infrastructure which was setup with the OpenStack cloud software on the Fedora Linux operating system. The pilot project execution findings exhibit a reduction in the timespan borne by instances for executing load balancing. This technique is useful for attaining fault tolerance and efficient resource utilization in intracloud and intercloud environments.

Optimizing Educational Efficiency: Exploring the Relationship Between Bulk and Clinical Rotation Group Size in Medical Education Students’ Perspective in Busitema University Uganda

Clinical rotation group size plays a pivotal role in shaping the quality, efficiency, and overall student experience in medical education. Despite its significance, determining the ideal group size remains a daunting task. This research endeavors to delve into the correlation between group size and what is termed as "bulk," representing the comprehensive efficiency and productivity of clinical rotation groups. By examining this relationship, the study aims to offer valuable insights into potential strategies for optimizing group size, thereby enhancing the educational experience for medical students. The study employed a mixed-methods approach, combining quantitative analysis of productivity metrics with qualitative assessments of student and faculty perceptions. Surveys, interviews, and observational data were utilized to capture the nuances of group dynamics, learning outcomes, and resource utilization across different group sizes. Statistical techniques such as regression analysis and ANOVA were employed to identify significant correlations and differences. Data were collected from medical students undergoing clinical rotations across multiple specialties. Group sizes varied from small (2-3) and large (4 and more). The study measured bulk using indicators such as patient encounters per student, learning outcomes, and faculty-student interaction. Results indicated a nonlinear relationship between bulk and group size. Smaller groups showed higher individual student engagement, personalized learning experiences, and increased faculty-student interaction. Conversely, larger groups exhibited greater overall productivity due to economies of scale and enhanced peer learning. However, beyond a certain threshold, further increases in group size led to diminishing returns, compromising individualized attention and educational quality. The findings underscore the importance of balancing group size to optimize educational outcomes in clinical rotations. While larger groups may offer efficiency gains, they must be carefully managed to mitigate potential drawbacks such as reduced individualized attention and faculty-student interaction. Smaller groups foster a more personalized learning environment but may lack the resource utilization efficiency of larger cohorts. Institutions should consider contextual factors such as specialty, learning objectives, and available resources when determining optimal group sizes. In conclusion, the relationship between bulk and clinical rotation group size is complex, with both benefits and limitations associated with different group sizes. Institutions should strive to strike a balance between efficiency and educational quality by tailoring group sizes to specific contexts and objectives. Further research is needed to explore additional factors influencing bulk and to develop targeted interventions for optimizing clinical rotation experiences.

Dynamic event-triggered fixed-time consensus control for coupled multi-permanent magnet synchronous motors stochastic system with prescribed performance

With the ubiquity of permanent magnet synchronous motors (PMSM), multi-PMSMs are increasingly being elastically coupled to achieve greater output power. The authors establish a general mathematical model of coupled multi-PMSMs system. The dynamic analysis of the coupled multi-PMSMs system is analyzed using coupled three-PMSMs system as an example, and a dynamic event-triggered fixed-time consensus controller with prescribed performance is constructed for coupled PMSMs stochastic system. In addition, Interval Type-3 Fuzzy System (IT3FS) is employed to estimate unknown functions, the computing cost is reduced by updating the weights based on only one adaptive law per PMSM. To enhance the efficiency of communication resource utilization, a dynamic event-triggered mechanism is introduced, where the triggering condition depends on a dynamic auxiliary variable. Moreover, fixed-time control technical is applied to guarantee the setting time and a novel fixed-time prescribed performance function (PPF) is constructed to constrain consensus errors. To cope with the “complexity explosion”, a fixed-time tracking differentiator (TD) is introduced and the corresponding filtered error compensation signals is designed. Finally, the authors demonstrate the system is fixed-time stabilized in probability by applying fixed-time stabilization Lyapunov stability criterion, and the simulation results of a coupled three-PMSMs stochastic system show that the presented algorithm is feasible.

Extraction and In Vitro Skincare Effect Assessment of Polysaccharides Extract from the Roots of Abelmoschus manihot (L.).

Obtaining high-added value compounds from agricultural waste receives increasing attention, as it can both improve resource utilization efficiency and reduce waste generation. In this study, polysaccharides are extracted from the discarded roots of Abelmoschus manihot (L.) by the high-efficiency ultrasound-assisted extraction (UAE). The optimized condition was determined as solid-liquid ratio SL ratio = 1:20, temperature T = 30 °C and time T = 40 min, achieving an extraction yield of 13.41%. Composition analysis revealed that glucose (Glc, 44.65%), rhamnose (Rha, 26.30%), galacturonic acid (GalA, 12.50%) and galactose (Gal, 9.86%) are the major monosaccharides of the extract. The extract showed a low degree of esterification (DE) value of 40.95%, and its Fourier-transform infrared (FT-IR) spectrum exhibited several characteristic peaks of polysaccharides. Inspired by the wide cosmetic applications of polysaccharides, the skincare effect of the extract was evaluated via the moisture retention, total phenolic content (TPC) quantification, 2,2-Diphenyl-1-picrylhydrazyl (DPPH)-free radical scavenging activity, anti-hyaluronidase and anti-elastase activity experiments. The extract solutions demonstrated a 48 h moisture retention rate of 10.75%, which is superior to that of commercially available moisturizer hyaluronic acid (HA). Moreover, both the TPC value of 16.16 mg GAE/g (dw) and DPPH-free radical scavenging activity of 89.20% at the concentration of 2 mg/mL indicated the strong anti-oxidant properties of the extract. Furthermore, the anti-hyaluronidase activity and moderate anti-elastase activity were determined as 72.16% and 42.02%, respectively. In general, in vitro skincare effect experiments suggest moisturizing, anti-oxidant, anti-radical and anti-aging activities of the A. manihot root extract, indicating its potential applications in the cosmetic industry.

The prevalence and pattern of comorbid long-term conditions with low back pain and osteoarthritis in low- and middle-income countries: a systematic review and meta-analysis

ABSTRACT Chronic musculoskeletal (MSK) pain, specifically low back pain (LBP) and osteoarthritis (OA), are a major cause of global disability, reduced quality of life and high socioeconomic burden. Research in high income countries suggests MSK pain is often comorbid with other long-term conditions / non-communicable diseases (NCDs) including diabetes, hypertension, and cardiovascular disease. However, the epidemiology of comorbid NCDs and MSK pain in low- and middle-income countries (LMICs) is unclear. This systematic review aims to describe the prevalence and pattern of comorbid NCDs in adults with MSK pain in LMICs. Nine databases were searched for epidemiological studies in LMICs (World Bank categories). Paired researchers independently identified studies, extracted data, and completed critical appraisal using Hoy risk of bias tool. Random-effect meta-analysis was used to estimate prevalence of NCDs comorbid with MSK pain. From 2112 citations; 14 studies (n=6093 adults with MSK pain, mean age=46.9years) were included. Overall prevalence of MSK pain with comorbid NCDs was 46.1% (95%CI 32.3 - 59.9). Systemic hypertension had the highest comorbid prevalence with MSK pain (42.6%, 95%CI 25.6-59.6), followed by diabetes (26.7%, 95%CI 16.1-37.3) and mental health conditions (anxiety/depression; 24.9% 95%CI 11.5-38.4). A high proportion of patients with MSK pain in LMICs experience comorbid NCDs. Variable data/population samples, and under-reporting limit accurate capture of prevalence estimates. Understanding the true burden of MSK pain (specifically lower back pain and hip/knee osteoarthritis) and comorbid NCDs is critical to informing effective treatment strategies. The health systems implications of these findings are imperative towards person-centred care, organisation of care and efficient resource utilisation in LMICs.

Experimental and numerical investigation on the pyrolysis of oil shale particles in a bubbling fluidized bed

The efficient utilization of oil shale resource is beneficial to environment and the resource diversity. In this work, a bubbling fluidized bed (BFB) reactor was first used to pyrolyze Huadian oil shale experimentally, mainly focusing on the influence of fluidization flow rates. The yield of shale oil, char and non-condensable gas varies little at different fluidization flow rates, but the components in shale oil are different due to the secondary cracking, such as the fractions and species of aliphatic hydrocarbons, aromatic hydrocarbons and non-hydrocarbons. Then, the dense discrete phase model (DDPM) was used to track the trajectories of oil shale particles with different diameters in a bubbling fluidized bed. Population balance model (PBM) coupled Eulerian model was used to well describe the bubbling status of bed materials to characterize the hydrodynamic behaviors. Furthermore, a segmented kinetic model was compiled by UDF module to illuminate the pyrolysis of oil shale particles. The multi-phase reactive flow modeling clearly indicated the distribution of oil shale particles and gaseous products in BFB reactor, as well as pyrolysis time and the secondary cracking at different fluidization flow rates. In summary, this work provides a reference basis for complete pyrolysis of oil shale particles in a bubbling fluidized bed and generating shale oil with high yield and good quality.

Green conversion of carbon disulfide to degradable polydithiourethanes through catalyst-free multicomponent polymerizations of diamines, carbon disulfide and diacrylates

In the pursuit of advanced functional polymer materials, sulfur-containing polymers have received tremendous attention owing to their superior chemical stability, high refractive indices, various supramolecular interactions, and robust dynamic covalent chemistry. However, their synthesis usually involves either expensive monomers or toxic byproducts and requires catalysts, thus hindering their widespread application. In this work, we present a catalyst-free multicomponent polymerization in organic solvents for the synthesis of various polydithiourethanes with excellent yields (up to 98 %) and high molecular weights (up to 112 kg/mol). This reaction involves the direct polymerization of carbon disulfide, an abundant one-carbon feedstock, with commercially available diamines and diacrylates. This polyaddition process demonstrates high atom economy and no byproduct, occurring at room temperature without the need for a catalyst, thus exhibiting excellent green chemistry metrics. By utilizing the dynamic covalent chemistry of dithiourethane groups, these polymers can be efficiently degraded via aminolysis and used to fabricate reprocessable vitrimers. This multicomponent polymerization opens up a new avenue for the efficient utilization of carbon disulfide resources and accelerates the exploration of diversified sulfur-containing functional polymer materials.

Research on the coordinated relationship between sewage resource utilization and economic research on the coordinated relationship between "dual-cycle" wastewater resource utilization and economic development

Dual-cycle wastewater resource utilization is aimed at improving the utilization rate of water resources and reducing the discharge of urban wastewater in order to increase the utilization rate of natural resources and achieve the circular utilization of water resources during urban development. Based on the dual-cycle concept, this study aims to explore the coordination between wastewater resource utilization and economic development in China, and understand the impact between the two. Literature research and data analysis are mainly used to analyze data from different provinces in China, making the research practically valuable. Through the analysis of data from five different provinces, it is found that the better the economic development of a province, the higher the importance attached to wastewater resource utilization. However, due to the impact of rapid economic development, the efficiency of wastewater resource utilization shows a slow trend. Conversely, inland provinces that attach importance to wastewater resource utilization, despite some shortcomings in economic development, have strong potential for economic development, which reflects the coordination between the two. The overall coupling degree between wastewater resource utilization and economic development in China is in a stable growth trend, showing a primary level of coordination. To achieve advanced or even superior coordination, further research on the coordination between wastewater resource utilization and economic development based on the dual-cycle concept is needed. This research aims to provide reference value for improving the coordination between wastewater resource utilization and economic development and discover the relationship between the two under different economic development conditions, where regions with higher economic development efficiency have higher wastewater resource utilization rates, but there is no obvious coordination. Therefore, the research focuses on studying the coordination between wastewater resource utilization rates and economic development in different economic development regions, innovating the content of coordination research.

The novel transfer learning approach mitigates the time constraints associated with the traditional techniques and demonstrates a superior performance. This study aims to evaluate the effectiveness of convolutional neural networks (CNNs) and CNN-based transfer learning models in differentiating between aneurysmal subarachnoid hemorrhage (aSAH) and nonaneurysmal subarachnoid hemorrhage (naSAH). Data from Istanbul Ümraniye Training and Research Hospital, which included 15,600 DICOM images from 123 patients with aSAH and 7,793 images from 80 patients with naSAH, were used. The study employed four models: Inception-V3, EfficientNetB4, single-layer CNN, and three-layer CNN. Transfer learning models were customized by modifying the last three layers and using the Adam optimizer. The models were trained on Google Collaboratory and evaluated based on metrics such as F-score, precision, recall, and accuracy. EfficientNetB4 demonstrated the highest accuracy (99.92%), with a better F-score (99.82%), recall (99.92%), and precision (99.90%) than the other methods. The single- and three-layer CNNs and the transfer learning models produced comparable results. No overfitting was observed, and robust models were developed. CNN-based transfer learning models can accurately diagnose the etiology of SAH from CT images and is a valuable tool for clinicians. This approach could reduce the need for invasive procedures such as digital subtraction angiography, leading to more efficient medical resource utilization and improved patient outcomes.
