Back ground
: Schistosomiasis, caused by Schistosoma mekongi, remains public health concern on islands in the Khong district, Champasack province, Southern Lao PDR. Other helminth infections, including Opisthorchis viverrini, hookworm, and Trichuris trichiura, are also prevalent on these islands. This study aimed to assess the impact of an Eco-health/One-health intervention package combined with mass drug administration (MDA) on these helminth infections.
Methods
We conducted a community intervention using a stepped-wedge trial approach on two endemic islands (Donsom and Donkhone) of the Kong district, Champasack province, Lao PDR, between April 2012 and March 2013. After the baseline (T0), the eco-health/one-health intervention package was implemented on Donsom (intervention) and Donkhone island (control). An assessment was conducted in 2014 (T1), one year after the completion of intervention implementation, to assess the short-term impact of the Eco-health/One-health intervention package on helminth infections and compare intervention and control islands. Later in 2015, the Eco-health/One-health intervention package was implemented on control island (Donkhone). After the implementation of intervention, the parasitological assessments were conducted annually in humans in 2015 (T2), in 2016 (T3) and in 2017 (T4), and in dogs in 2017 (T4) to evaluate the long-term impact of the intervention on helminth infections.
Results
Results showed that the Eco-health/One-health intervention package significantly reduced the infection with S. mekongi by 9.0% compared to the use of mass drug administration alone (control island). Additionally, this intervention package significantly reduced O. viverrini infection by 20.3% and hookworm by 17.9%. Annual parasitological assessments between 2012 and 2017 showed that the eco-health/one-health intervention package, coupled with MDA, steadily reduced the prevalence of S. mekongi on the intervention island from 29.1–1.8% and on the control island from 28.4–3.1%, respectively.
Conclusion
The study findings suggest that the Eco-health/One-health intervention significantly contributes to the prevalence reduction of S. mekongi and helminth co-infections, particularly hookworm and T. trichiura. Therefore, implementing the Eco-health/One-health intervention in schistosomiasis-endemic areas could accelerate the achievement of national goals for transmission interruption by 2025 and elimination by 2030.

Authors: Qianzhe Chen , Liu Lie
Published: April 2024

Imidst the rapid development of society and economy, we are inevitably confronted with the recurrent challenges of accidents and disasters. However, the continuous advancement in science and technology, particularly the breakthroughs in the field of laser technology, has provided us with robust support to tackle these challenges. Modern laser technology, acclaimed as the magical "sword" capable of effortlessly "cutting iron like mud," has demonstrated unparalleled efficacy in the domain of rescue and demolition. Its precise and swift cutting capabilities have significantly reduced the risk of casualties in rescue operations, shortened the critical time required for demolition tasks, and greatly enhanced the efficiency and precision of the work. The application of this technology not only highlights the immense potential of technological innovation but also offers invaluable support and assurance for our rescue efforts in emergency situations. To explore the application of laser cutting technology in rescue and demolition, this paper focuses on Q235 steel plates with thicknesses of 8mm and 15mm, conducting laser cutting experiments with a fiber laser at a long distance to investigate its suitability for rescue and demolition. The experimental results indicate that the optimal cutting effects are achieved when the distance between the laser head and the workpiece is 10m with a cutting speed of 2.00mm/s and a laser power of 10kW, and when the distance is 13m with a cutting speed of 2.25mm/s and a laser power of 13kW. Appropriately selecting the cutting speed and laser power is crucial for enhancing the surface quality of the cut on Q235 steel plates and reducing the occurrence of root slag, which is essential to meet the demands of the rescue and demolition field.
Estimation method for geometric stability during shoe-type centerless grinding of rolling bearing parts
Authors: Zakharov Oleg , Grigoriev Sergey , Li Chen
Published: April 2024

Centerless grinding is one of the most productive machining methods and is used in the mass production of automotive parts and rolling bearings. Shoe-type centerless grinding allows precise machining of the outer and inner shaped surfaces of bearing rings. Reducing tolerances on the size and shape of bearing parts requires improved centerless grinding. The most difficult thing is to ensure the roundness is less than 1 mm. This requires the development of mathematical models of a high degree of adequacy. This paper presents a new estimation method for geometric stability based on computer simulation. A mathematical model of centerless location on shoes with the high degree of adequacy to the real process has been developed. The main innovations of the developed method were a numerical algorithm for searching for points of contact between the part and the shoes and equation for determining the center of the part as the point of intersection of the trajectory of its movement along the opposite shoes. Based on computer modeling, the trajectories of movement of the profile points were studied and the patterns of geometric stability were established. An evaluation indicator is proposed in the form of the maximum trajectory error of the profile point during one full turn of the part. The possibility of optimizing machining by setting up shoe angles has been confirmed. Experimental verification confirmed high geometric stability due to the shoes location according to the new model.

Published: April 2024

Background
In forest ecosystems, biological decomposition of deadwood components plays a pivotal role in nutrient cycling and in carbon storage by enriching soils with organic matter. However, deciphering the functional features of deadwood microbiomes is challenging due to their complexity and the limitations of traditional cultivation methods. Our study demonstrates how such limitations can be overcome by describing metagenome composition and function through the analysis of long DNA molecules using the PacBio HiFi platform.
Results
The accuracy of PacBio HiFi long-read sequencing emerges as a robust tool for reconstructing microbial genomes in deadwood. It outperformed the routine short-read sequencing and genome sequencing of isolates in terms of the numbers of genomes recovered, their completeness, and representation of their functional potential. We successfully assembled 69 bacterial genomes representing seven out of eight predominant bacterial phyla, including 14 high-quality draft MAGs and 7 nearly finished MAGs. Notably, the genomic exploration extends to Myxococcota, unveiling the unique capacity of Polyangiaceae to degrade cellulose. Patescibacteria contributed to deadwood decomposition processes, actively decomposing hemicellulose and recycling fungal-derived compounds. Furthermore, a novel nitrogen-fixing bacteria within the Steroidobacteriaceae family were identified, displaying interesting genomic adaptations to environmental conditions. The discovered diversity of biosynthetic gene clusters highlights the untapped potential of deadwood microorganisms for novel secondary metabolite production.
Conclusions
Our study emphasizes new contributors to wood decomposition, especially Polyangiaceae and Patescibacteria for complex and easily decomposable organic matter, respectively. The identification of nitrogen-fixing capabilities within the Steroidobacteraceae family introduces novel perspectives on nitrogen cycling in deadwood. The diverse array of observed biosynthetic gene clusters suggests intricate interactions among deadwood bacteria and promises the discovery of bioactive compounds. Long read sequencing not only advances our understanding of deadwood microbial communities but also demonstrates previously undiscovered functional capacities of the deadwood microbiome. Its application opens promising avenues for future ecological and biotechnological exploration of microbiomes.

Authors: He Ke , Liu Suijun , Shi Jingbo , Zhang Peng , Chen Lian , Wang Bozhao , Zhang Juan
Published: April 2024

Background
Diabetes can cause chronic microvascular complications such as diabetic retinopathy (DR) and diabetic nephropathy (DN). DR and DN can lead to or exacerbate diabetic macular edema (DME). Hemodialysis (HD) is the main treatment method for patients with end-stage kidney disease (ESKD) secondary to DN.
Purpose
The aim of this prospective cohort study was to determine the changes in retinal and choroidal thickness in patients with ESKD before and after HD and the impact of long-term HD on DR.
Methods
Eighty-five eyes of 44 DR patients with ESKD who underwent HD were examined by swept-source optical coherence tomography angiography (SS-OCTA). Based on OCTA images, the characteristics of DR and the prevalence of DME in these patients were analyzed. Changes in central retinal thickness (CRT), central retinal volume (CRV), subfoveal choroidal thickness (SFCT) and subfoveal choroidal volume (SFCV) within 30 minutes before and after HD were compared. CRT, CRV, SFCT and SFCV were compared before HD and before the next HD.
Results
There was no significant difference in the average CRT (251.69 ± 39.21 µm vs. 251.46 ± 39.38 µm, P = 0.286) or CRV (0.15 ± 0.62 µm vs. 0.15 ± 0.63 µm, P = 0.324) between before and after HD. After HD, SFCT (243.11 ± 77.15 µm vs. 219.20 ± 72.84 µm, P < 0.001) and SFCV (0.15 ± 0.10 µm vs. 0.13 ± 0.90 µm, P < 0.001). significantly decreased. There was no statistically significant difference in CRT (251.69 ± 39.21 µm vs. 251.11 ± 38.47 µm, P = 0.206), CRV (0.15 ± 0.62 µm vs. 0.15 ± 0.61 µm, P = 0.154), SFCT (243.11 ± 77.15 µm vs. 245.41 ± 76.23 µm, P = 0.108), or SFCV (0.15 ± 0.10 µm vs. 0.16 ± 0.10 µm, P = 0.174) before HD and before the next HD. On en face OCTA images, eighty-five eyes (100%) had retinal nonperfusion areas, focal avascular zone (FAZ) enlargement, and abnormal retinal microvasculature. Based on cross-sectional OCTA images, retinal neovascularization (RNV) was confirmed in 42 eyes (49.41%), and intraretinal microvascular abnormalities (IRMAs) were detected in 85 eyes (100%). Seventeen eyes (20%) still had DME, and all had cystoid macular edema (CME). Among eyes with DME, the epiretinal membrane (ERM) was present in 7 eyes (8.24%).
Conclusions
For DR patients with ESKD who have undergone long-term HD, the choroidal thickness still changes significantly before and after HD, which may be related to short-term effects such as reduced blood volume and plasma osmotic pressure caused by HD. Although HD can improve DME, the DR of patients with ESKD should still be given attention.

Published: April 2024

Purpose
Ovarian cancer is the deadliest of all gynaecological malignancies, making it a major public health concern. Major global research finding highlighted a low level of ovarian cancer knowledge and education among women of reproductive age. The study assessed knowledge, perception, and intended healthcare-seeking behaviour for ovarian cancer among female undergraduate students of University of Ibadan.
Methods
This cross-sectional survey involved 275 female undergraduate students of the University of Ibadan selected by a four-stage sampling technique. A semi-structured self-administered questionnaire was used to obtain data on their socio-demographic characteristics, knowledge, perception, and intended healthcare-seeking behaviour toward ovarian cancer. Data was analysed using Chi-square, Spearman’s rank order correlation, Mann-Whitney U and Kruskal-Wallis H tests with α ≤ 0.05.
Results
Age was 22.12 ± 2.2 years and 76% were Christians. Majority (95.3%) were aware of ovarian cancer however, only 33.2% had good knowledge. The top-two identified symptoms were abdominal pain (66%) and pelvic pain (63.8%). Over two third, (68.3%) had poor knowledge of its risk factors. Having ovarian cysts (29.5%) was the commonly recognized risk factor while the least was “menopause” (16.4%). Majority had moderate perceived susceptibility and severity, but high perceived benefits, cues to action and self-efficacy. The majority (80.2%) intended to visit the health facility once they notice any symptoms of ovarian cancer and (66.0%) plan to do so within a few days. Knowledge was significantly and positively correlated with perception, the strongest was with perceived severity (p < 0.001).
Conclusion
The female undergraduate students had low knowledge of ovarian cancer, but high intention to seek medical help. The results highlight the need for multi-component educational interventions and strengthening of the health system.
The “SEP clock”: A discussion of first proton arrival times in wide-spread solar energetic particle events
Authors: Posner A. , Richardson I. G. , Strauss R. D.-T.
Published: April 2024

This work analyzes the appearance of wide-spread deka-MeV solar energetic proton (SEP) events, in particular the arrival of the first protons within ~ 4.5–45 MeV measured at Earth-Sun L1, and their relationship with relative solar source longitude. The definition of “wide-spread SEP event” for this study refers to events that are observed as a 25 MeV proton intensity increase at near-1 AU locations that are separated by at least 130ᵒ in solar longitude. Many of these events are seen at all three of the spacecraft, STEREO A, STEREO B, and SOHO, and may therefore extend far beyond 130ᵒ in longitude around the Sun. A large subset of these events have already been part of a study by Richardson et al. (2014). The event source region identifications draw from this study; more recent events have also been added. Our focus is on answering two specific questions: (1) What is the maximum longitude over which SEP protons show energy dispersion, i.e., a clear sign of arrival of higher-energy protons before those of lower energy? (2) What implications can be drawn from the ensemble of events observed regarding either direct magnetic connectivity to shocks and/or cross-field transport from the site of the eruption in the onset phase of the event?

Authors: Deng Nanxiao , Zhou Ya , Wang Yabing , Huang Guimin , Li Yiqun , Chen Jingru
Published: April 2024

With the rapid development of Internet technology, a massive amount of English text has emerged, creating an urgent need to evaluate the semantic similarity of these texts across different domains. Existing research on semantic similarity faces the challenge of insufficient prior knowledge. Therefore, a new method has been proposed, called Knowledge Prior Topic Model (KPTM), for analyzing text semantic similarity. This method incorporates semantic relationship data from the large-scale English knowledge base, Probase, into the topic model and combines it with an effective keyword serialization approach to calculate the hybrid measurement of concepts and keywords for text similarity. Experimental results demonstrate that the proposed method contributes to improving semantic similarity and outperforms other models in comparative experiments.

Authors: Xia Yongquan , Li Keyun , Li Duan , Nan Jiaofen , Lu Ronglei , Meng Yinghui , Zhu Fubao , Yao Ni , Han Chuang , Li Yanting , Liu Peisen , Zhu Tanxin
Published: April 2024

The brain-computer interface (BCI) based on steady-state visual evoked potential (SSVEP) has gained increasing attention due to its non-invasiveness, low user training requirement, and high information transfer rate. In order to enhance the performance of SSVEP detection, we propose an improved joint model that combines variational mode decomposition (VMD) and wavelet fusion with filter bank canonical correlation analysis (FBCCA). The model is validated on awearable SSVEP-BCI dataset. By integrating decomposition and denoising techniques, the model employs DFA thresholding and applies deep filtering using discrete wavelet transform (DWT) and wavelet packet transform (WPT) to denoise the wearable EEGs. The filtered components are reconstructed along with the components that do not require filtering. Subsequently, identification is conducted using FBCCA, which employs a combination of filters to delineate frequency bands. Ultimately, the classification accuracy for dry and wet electrodes reaches 72.46% and 88.29% respectively. Compared to existing research results on this dataset, dry and wet electrodes show improvements of around 13% and10% respectively. This hybrid model provides a new perspective for wearable SSVEP recognition research and holds high potential for widespread application.

Authors: Chi Jiaxing , Liu Chang , Wang Peng , Li Wenbo , Zhang Xiang , Guo Haoxin , Li Xiaorong , Hu Bojie
Published: April 2024

Background: Myopia has shown a sharp upward trend worldwide and has become a global public health concern. However, there were insufficient correction rates all over the world. This study aimed to investigate the prevalence of myopia and spectacle-wearing rate in primary and high school students in Yicheng, as well as analyze the risk factors of myopia onset and development.
Methods: The Yicheng Myopia Study was a school-based cross-sectional study of primary and high school students in Yicheng District, Shandong Province, China. The refractive error was measured using an autorefractor without cycloplegia and recorded as a spherical equivalent refraction (SER). Visual acuity was recorded as uncorrected visual acuity (UCVA). Only worse SER and UCVA values between the two eyes were analyzed. Myopia was defined as SER < -0.50 D and UCVA > 0.2 using the logarithm of the minimum angle of resolution. Correction rate (CR) was the ratio of individuals wearing spectacles in myopia students.
Results: A total of 37,908 primary and high school students were included (16,826 girls, mean age of 11.68 ± 3.04 years). In total, 15,779 students were myopic. Older age, female sex, and schooling in urban areas were risk factors for myopia. Correction rates were low among students in Yicheng. And there were obvious relative visual acuity insufficiency among low and moderate myopia students, especially in high grades students.
Conclusions: The prevalence of myopiain the Yicheng student population was 41.6%. The proportion of students with uncorrected myopia was high.Further research should be conducted to identify specific socioeconomic factors that contribute to myopia and to lower the incidence of myopia by lowering the exposure to these factors.

Authors: Malik Muhammad Ghulam Abbas , Bashir Zia , Akhtar Muhammad Waseem , Awais Muhammad
Published: April 2024

The study of variable order differential operators has emerged as a powerful tool for effectively modeling nonlinear fractional differential equations and chaotic systems. In this research, we employ a nonlinear, flexible structure of radial basis function neural network (RBFNN) to model the convective flow of the generalized nonlinear Volta's system in the variable order fractional domain. The intricate physical parameters of the fractional-order system are first computed using a Variable Caputo-Fabrizio scheme, considering diverse stochastic scenarios of control constraints. Following this, we craft a parametric model using a Radial basis function neural network under various initial conditions and variable order of the generalized variable order Volta's system. We compute diverse manifestations of chaos within Volta's system using a dynamical neural network structure across different fractional order solutions. The phase portrait of the chaotic attractor demonstrates the chaotic behavior of the generalized variable order fractional Volta system through the Lyapunov exponent. We calculate time delay and embedded dimension using the Average Mutual Information (AMI) method to reconstruct the phase space for generalized variable order Volta's system. The proposed configuration of the Radial basis function neural network has been verified as an exceptionally effective tool for both soft computing and dynamics analysis of chaotic systems within the variable order fractional domain.
Educational Policy as Predictor of Computational Thinking: A Supervised Machine Learning Approach
Authors: Ezeamuzie Ndudi O. , Leung Jessica S. C. , Fung Dennis C.L. , Ezeamuzie Mercy N.
Published: April 2024

Background: Computational thinking is derived from arguments that the underlying practices in computer science augment problem-solving. Most studies investigated computational thinking development as a function of learners’ factors, instructional strategies and learning environment. However, the influence of the wider community such as educational policies on computational thinking remains unclear.
Objectives: This study examines the impact of basic and technology-related educational policies on the development of computational thinking.
Methods: Using supervised machine learning, computational thinking achievements of 31,823 eighth graders across nine countries were analysed. Seven rule-based and tree-based classification models were generated and triangulated to determine how educational policies predicted students’ computational thinking.
Results and Conclusions: Predictions show that students have higher propensity to develop computational thinking skills when schools exercise full autonomy in governance and explicitly embed computational thinking in their curriculum. Plans to support students, teachers and schools with technology or introduce 1:1 computing have no discernible predicted influence on students’ computational thinking achievement.
Implications: Although predictions deduced from these attributes are not generalizable, traces of how educational policies affect computational thinking exist to articulate more fronts for future research on the influence of educational policies on computational thinking.
An optimization scheme for vehicular edge computing based on Lyapunov function and deep reinforcement learning
Authors: Zhu Lin , Li Bingxian , Tan Long
Published: April 2024

Traditional vehicular edge computing research usually ignores the mobility of vehicles, the dynamic variability of the vehicular edge environment, the large amount of real-time data required for vehicular edge computing, the limited resources of edge servers, and collaboration issues. In response to these challenges, this paper proposes an allocation and collaboration scheme of vehicle edge computing resources based on the Lyapunov function and Twin Delayed Deep Deterministic Policy Gradient (TD3). In this solution, this paper uses Digital Twin technology (DT) to simulate the vehicular edge environment. The edge server DT is used to simulate the vehicular edge environment under the edge server, and the base station DT is used to simulate the entire vehicular edge system environment. Based on the real-time data obtained from DT simulation, this paper defines the Lyapunov function to simplify the migration cost of vehicle tasks between servers into a multi-objective dynamic optimization problem. It solves the problem by applying the TD3 algorithm. Experimental results show that compared with other algorithms, this scheme can effectively optimize the allocation and collaboration of vehicular edge computing resources and reduce the delay and energy consumption caused by vehicle task processing.

Published: April 2024

Backgroud
The prevalence of multimorbidity ( ≥2 chronic disorders in the same individual), polypharmacy ( ≥5 medications in the same individual) and potentially inappropriate medications (PIMs) in elderly patients was very high.
Methods
This is a cross-sectional analysis of 276 elderly patients aged ≥65 years old. PIMs was analyzed based on the Beers criteria (2019 edition) and Chinese criteria, patients were divided into non-PIMs, 1PIMs and ≥2 PIMs group based on both critieria. Logistic regression analysis wasconducted to investigate factors related to PIMs.
Results
The prevalence of multimorbidity was as high as 96.74% (n=267). 91.30% of patients (n=252) had polypharmacy. Determined by Beers and Chinese criteria, 40.22% (n=111) and 41.30% (n=114) of patients had 1 PIMs, 26.09% (n=72) and 13.77% (n=38) of patients had 2 or more PIMs. Based on Beers criteria, patients with PIMs had more prescribed medications compared to patients with non-PIMs (median [inter-quartile range, IQR]: 10[7–12] vs.7[5-9]), patients with 2 or more PIMs had significant more prescribed medications compared to patients with 1 PIMs (11[9.25-13] vs 8[7-11]); Similar results was found based on Chinese criteria. Further logistic regression analysis showed that the strongest predictor of PIMs was increased number of prescribed medications as determined by both Beers and Chinese criteria (P<0.001). Gender, number of diseases or age was not risk factor correlated to PIMs in our study.
Conclusion
PIMs in the elderly was very common, increased number of prescribed medications was the strongest predictor of PIMs.

Published: April 2024

The radio frequency interference (RFI) in global navigation satellite system (GNSS) signals has recently received much attention in the GNSS community because of frequent jamming issues. The carrier-to-noise density ratio (C/N0) is one of the common parameters to indicate the signal quality. In this work, we aim to analyze the occurrences of local RFI effects in areas surrounding the Suvarnabhumi International Airport as well as remote areas. Specifically, the percentage of RFI levels and raw C/N0 values are analyzed based on the modified RFI detection. The estimated RFI values are created from the raw C/N0 data, followed by the RFI levels generated by the empirical data. We validate the modified RFI detection by using the GNSS reference stations at the urban, suburban, and outside the capital city in Thailand. The user positioning errors with the high (severe) RFI levels are investigated based on the single point positioning (SPP) and real-time kinematics (RTK). From the experimental simulations, the high RFI levels at the urban are higher than those at the suburban. As expected, the statistical analysis covering COVID-19 (2019 to 2023) shows that the high RFI levels in June 2023 (post COVID-19) are more than those in June 2020 and 2021 (lockdown COVID-19) about twofold. Additionally, the SPP and RTK errors with the medium/high RFI levels have the error spikes in the centimeter to meter levels. The RTK performance with the fixed status can be affected and then returned to the float status as well.

Published: April 2024

Objective
The Chitinase 3-like protein 1 (CHI3L1) is currently used as a biomarker for the diagnosis of liver fibrosis. However, its prognostic value for hepatocellular carcinoma (HCC) patients remains controversial. In this study, we aimed to investigate the prognostic value of the CHI3L1 in HCC patients after hepatectomy.
Methods
In total, 754 HCC patients who underwent curative hepatectomy between January 2017 to August 2021 were retrospectively recruited. The probability of overall survival (OS) was evaluated by the Kaplan-Meier method and compared between groups using the log-rank test. Cox proportional hazard regression analysis was used to determine the independent prognostic factors. A prognostic nomogram was constructed for further examine the clinical utility of CHI3L1 in HCC.
Results
Kaplan-Meier analysis revealed that elevated serum CHI3L1 levels were associated with worse overall survival of HCC patients. Multivariate Cox regression analysis showed that the high-CHI3L1 group (≥198.94 ng/ml) was associated with a shorter survival time compared with that in the low-CHI3L1 group (< 198.94 ng/ml) after adjustment for potential confounding factors (HR =1.43, 95% CI = 1.05-1.94, P = 0.024). Additionally, the nomogram had sufficient calibration and discriminatory power in the training cohort, with C-indexes of 0.723 (95% CI: 0.673-0.772). The validation cohort showed similar results. Finally, we demonstrated that the AUC of the nomogram was 0.752 (95% CI: 0.683-0.821), which had better predictive ability than AFP (AUC: 0.644, 95% CI: 0.577-0.711).
Conclusion
Our results confirmed that the CHI3L1 could serve as an independent predictor for OS in HCC patients after hepatectomy, thus helping clinicians to develop individualized treatment and follow-up plans for the HCC patients. Further confirmation is needed due to the study limitations.

The emergence of new diseases on plant leaves poses a substantial threat to global food safety and agricultural productivity. To mitigate this risk, accurate and swift detection of plant illnesses is crucial, reducing unnecessary expenses and minimizing financial losses and environmental damage. This study proposes a method called Plant Leaf Disease Detection with a Constitutive Artificial Neural Network (PLDD-CANN) to provide advancements in deep learning. The approach begins by gathering data from the Plant Village dataset and subjecting it to pre-processing techniques. This includes noise removal and image enhancement using a Variational Marginalized Particle Filter (AVMPF). Next, an Adaptive Convex Clustering (ACC) method is employed for image segmentation, followed by feature extraction using Fast Fourier and Continuous Wavelet (FFCWT) transforms. Finally, a Constitutive Artificial Neural Network (CANN) is utilized to categorize the input image to one of several categories, including healthy and various disease types like Yellow Leaf Curl Virus, Septoria Leaf Spot, Two-Spotted Spider Mite, Bacterial Spot, Target Spot, Leaf Mold, Mosaic Virus, Early Blight, and Late Blight. Then, the proposed technique is simulated using Python under several performance metrics including precision, f1-score, error rate accuracy, sensitivity, specificity and ROC. The proposed PLDD-CANN method provides 26.75%, 25.83% and 27.46% higher accuracy comparing with existing methods an enhanced CNN technique for plant leaves disease diagnosis in tomato (CNN-PLDD), A Novel Approach for Plant Leaf Disease Predictions with Recurrent Neural Network RNN Classification Method (RNN-PLDD), Detection of tomato leaf diseases for agro-based industries (FRCNN-PLDD) respectively.

Nursing students have a crucial role to play in healthcare services while they are in training. It is an essential step in their professional practice preparation. Unfortunately, nursing students often experience obstacles such as bullying behavior which makes some of them drop out of nursing education, regardless of their geographic location. With the increasing brain drain of nurses in Ghana, the nurse-patient ratio is likely to rise further if the phenomenon is not given attention. Therefore, it is crucial to thoroughly evaluate nursing students' bad experiences in the clinical learning environment for a remedy. Hence, the researchers aim to analyze the obstacles faced by nursing students during their clinical attachments in hospitals located in Koforidua, Ghana's Eastern Region. A cross-sectional survey was conducted using a convenient sampling technique to select 130 nursing students from specific clinical learning environments. The study found that male nursing students (OR = 3.27 [95% CI: 1.67–4.88], p < 0.01), nursing students who are married (OR=-0.89 [95% CI: -2.57-0.80], p = 0.30), and Muslim nursing students (OR=-0.68 [95% CI: -2.27-0.41], p = 0.17) were more likely to be dissatisfied with their clinical learning environment compared to female, unmarried, and Christian nursing students, respectively. Male nursing students, Muslim nursing students, married nursing students, and nursing students who were relatively old were more likely to drop out of nursing school due to their intolerance of bullying and disrespect in the clinical environment, which led to dissatisfaction with their clinical experience.
Thermal effects and ephaptic entrainment in Hodgkin-Huxley model

The brain is understood as an intricate biological system composed of multiple elements. It is susceptible to diverse physical and chemical influences, including temperature. The literature widely explores the conditions that affect synapses in the context of cellular communications. However, the understanding of how brain global physical conditions can modulate ephaptic communication remains limited, because the still poorly understood nature of ephapticity. This study proposes an adaptation of the Hodgkin and Huxley model, HH-E, to investigate the effects of ephaptic entrainment in response to thermal changes. The analysis focus on two distinct neuronal regimes: subthreshold and suprathreshold. In the subthreshold regime, the circular statistic is used to show the phase differences dependence on temperature. In the suprathreshold regime, the Population Vector and the Inter-Spike Interval are used to estimate phase preferences and changes in the spiking pattern. Temperature affects positively the HH-E model spiking frequency. At high temperatures the HH-E model collapses and no more spiking are observed. Moreover, temperature difference improves the anti-phase between spikes and the ephaptic external signal. In the suprathreshold regime, the ephaptic entrainment is influenced by temperature, specially at low frequencies. Finally, this study reveals the susceptibility of ephaptic entrainment to temperature variations in both subthreshold and suprathreshold regimes and discusses the importance of ephaptic communication in pathological contexts in which temperature play an important role in neural physiology, such as inflammatory processes, fever and epileptic seizures.
Heinrich Rickert and the Specifics of the Methodology of Historical Knowledge (on the 160th Anniversary of His Birth)
Authors: Синицын О.В.
Published: April 2024

В статье характеризуется теоретико-методологическая концепция Генриха Риккерта, одного из ярких представителей «критической философии истории», основная проблематика которой была связана с вопросами возможностей и границ исторического познания. Главное внимание при этом было уделено защите научности истории, что базировалось на принципах методологического различения индивидуализирующих и генерализирующих наук. Эпистемология Риккерта строилась на критике теории отражения и противопоставлении обобщающего метода естественных наук, связанных с объектами, не имеющими ценностей и идеографического метода наук о культуре, имеющих дело с объектами, связанными с ценностями, что и обусловливает особенности исторических наук и специфику исторического познания.

The article characterizes the theoretical and methodological conception of Heinrich Rickert, one of the prominent representatives of the “critical philosophy of history”. The main attention is paid to protecting the scientific nature of history, which was based on the principles of methodological distinction between individualizing and generalizing sciences. Rickert's epistemology was based on criticism of the theory of reflection and opposition of the generalizing method of natural sciences, associated with objects that do not have values, and the ideographic method of cultural sciences, dealing with objects associated with values, which determines the features of the historical sciences and the specifics of historical knowledge. To reveal the diversity of all values, it is necessary to turn, according to Rickert, to the science that studies culture as reality, revealing all its richness, diversity, and uniqueness.
Vishwa Hindu Parishad: History for Export
Authors: Зайцев А.А.
Published: April 2024

Индийская диаспора является одной из крупнейших и влиятельных в мире, её численность превышает 30 млн чел. Индийцы в настоящее время расселены во множестве стран мира, их миграции способствовала сначала колониальная политика британцев, затем — изменение экономической ситуации в мире. Поэтому она имеет особое значение для современной Индии не только в контексте внешней политики страны как составляющая «мягкой силы», но и в плане распространения индийских традиций и ценностей, в т.ч. сведений об историческом прошлом страны. В настоящее время господствующее положение занимают последователи идеологии хиндутвы, соединённые в единую сеть организаций — Сангх паривар, где вопросом защиты и распространения традиций и ценностей индийцев занимается Вишва хинду паришад (ВХП). В статье показано, как сформировалась историческая концепция хиндутвы, какова роль в этом процессе у Вишва хинду паришад, какие методы используются для распространения концепции в странах с крупными индийскими диаспорами, в первую очередь на Западе, и как с процессом экспорта данной концепции связаны индологи-сторонники идеологии индусского национализма.

The Indian diaspora is one of the largest and most influential in the world with more than 30 million people. Indians are currently settled in many countries around the world; their migration was facilitated first by the colonial policy of the British, then by changes in the economic situation in the world. Therefore, it plays a special significance for modern India, not only in the context of the country’s foreign policy as a component of “soft power”, but also in terms of disseminating Indian traditions and values, including information about the country’s historical past. At present, the dominant position is occupied by followers of the Hindutva ideology, united in a single network of organizations of its supporters, which is the Sangh Parivar, where the Vishva Hindu Parishad (VHP) is engaged in the protection and dissemination of the traditions and values of Indians. The article indicates how the historical concept of Hindutva was formed, what is the role of the Vishwa Hindu Parishad in this process, what methods are used to spread the concept outside of India in countries with large Indian diasporas, primarily in the West, and how Indologists who support the ideology of Hindu nationalism are connected with the process of exporting this concept.
"One Day Museum of Everyday Life" and the Mirror of Memory Reflections on the New Book by Igor and Natalia Narskii

Статья посвящена книге Игоря и Натальи Нарских «Незаметные истории, или путешествие на блошиный рынок (Записки дилетантов)», вышедшей в серии «Культура повседневности» издательства «Новое литературное обозрение» в 2023 г. Несмотря на наличие сложившейся междисциплинарной традиции в изучении блошиного рынка, авторы книги демонстрируют собственный подход, рассматривая блошиный рынок как некое «другое», гетеротопическое пространство, пространство перехода, в ко-тором происходит встреча людей и вещей и устанавливаются особые отношения между ними. Рассказывая жизненные истории людей, «незаметных» обитателей этого рынка (продавцов, покупателей, фланеров), авторы параллельно реконструируют «истории жизни» вещей, для которых блошиный рынок становится новой точкой отсчета в их биографии. Специфика объекта исследования во многом определила жанровые особенности книги, полностью укладывающейся в рамки т.н. «лирической историографии», когда язык нарратива соединяет в себе черты художественного и научного текста, автобиографические реминисценции занимают равноправное место с академическими исследовательскими методами, а сами авторы – «дилетанты» и путешественники» в пестром и сложном мире блошиного рынка, вновь и вновь возвращаются туда как в пространство своих детских воспоминаний, материализованных в старых вещах как «местах памяти» о дорогих и любимых людях.

The article is devoted to Igor and Natalia Narskii's new book "Unnoticeable Stories, or a Journey to the Flea Market (Notes of Dilettantes)", published in 2023. Despite the existence of an established interdisciplinary tradition in the study of the flea market, the authors demonstrate their own approach, considering the flea market as a kind of “other”, heterotopic space − a space of transition in which people and things meet and a special relationship between them is established. By telling the life histories of people − the “invisible” inhabitants of this market (sellers, buyers, flyers), the authors reconstruct in parallel the life histories of things, for which the flea market becomes a new point of reference in their biography. The specificity of the object of study has largely determined the genre features of the book, which fully fit into the framework of the so-called "lyrical historiography", when the language of narrative combines the features of fiction and literature and scientific text, and autobiographical reminiscences take an equal place with academic research methods. The authors themselves − "dilettantes" and travelers" in the motley and complex world of the flea market, return there repeatedly as to the space of their childhood memories, materialized in the old things as "places of memory" about dear and beloved people.
