Preconditioning Strategies for Truncated Newton Full-waveform Inversion
Authors: Silva Bruno Santos , Costa Jessé Carvalho 
Published: May 2024

ABSTRACT. Truncated Newton full waveform inversion is an attractive alternative to conventional gradient-based optimization algorithms. This method accounts for the Hessian within the inversion; however, it is implemented in a "Hessian-free" fashion, without explicit calculation or storage of the Hessian matrix. At each iteration, we obtain the search direction through a conjugate-gradient (CG) solution of the Newton linear system, which requires only evaluations of Hessian-vector products. Due to the additional cost associated with inner CG iterations, it is indispensable to apply a preconditioning strategy on the CG algorithm to improve its convergence, reducing the number of CG iterations. In this work, we study two preconditioned CG schemes. We propose a scheme based on model reparameterization that adopts a preconditioner operator that combines smoothness and the illumination compensation effect of the pseudo-Hessian. We also investigate a more conventional preconditioning scheme that uses only the pseudo-Hessian preconditioner. The numerical experiments show that preconditioning using model reparameterization, which combines pseudo-Hessian compensation with smoothing, outperforms the more conventional preconditioning scheme that exclusively uses the pseudo-Hessian operator.

Published: May 2024

Various local communities living in India have been dependent on forests for centuries. The contribution of non timber forest products (NTFPs) has been recognized globallyfor their role in preservation, income generation, livelihood enhancement and rural development. About 275 million poor rural people in various regions of India are dependent on non-timber forest produce. The present study was conducted duringthe month of January to November 2022 to assess the major NTFPs and their role in livelihood generation in Bundelkhand region of Uttar Pradesh. Through surveys and interviews conducted in 4 study area (Viz. Banda, Jhansi, Mahoba and Chitrakut) of Bundelkhand, among the people of local communities, it has been revealed that even today the people of study area show their dependency on forest based NTFPs. Through harvesting, collection and processing of non-timber forest produce, providing new employment opportunities in the Bundelkhand region of India. In this region local people provide an overview of the dependency of different rural communities on NTFP’s such as salai gum, kullu gum, flowers and fruit of Mahua, baskets from bamboo and Harsingar, bidi from tendu leaves, Chironji seeds, jhadu from Date palm leaves, Amla, Bahera, Satavar and Nagarmotha for sustain their livelihood. Despite their significance to employment, NTFP markets are mostly informal andscattered, with no proper records maintained, leading to an insufficient information flowon the contribution of NTFP trade at the local as well as national level. There is an urgent need to promote all these things today so that the income of local collectors can be improved.
A Study on Detection Methods of Multi-Featured Fusion Teaching Factors in Blended College English Teaching
Authors: Wang Dale 
Published: May 2024

Abstract
The detection of teaching factors is mainly from the perspectives of both teachers and students, and the multi-feature fusion of the teaching factor detection method is used to add possibilities for the improvement of the quality of blended teaching of college English. The use of auditory features in this paper is to separate the teaching scene video and obtain the teacher and student video scenes. Teacher and student voice clustering algorithm based on teaching rules is proposed to complete the feature division, and the combination of visual and auditory features is used to extract the blended teaching behaviors of college English and classify the types of teacher and student behaviors and behavioral probabilities. Create a multi-feature fusion teaching factor detection model by optimizing the multi-feature fusion process and multi-feature fusion strategy. Design an experimental configuration to detect multi-feature teaching factors that affect students’ concentration, attention, and teaching state. The multi-feature fusion model’s recognition accuracy for excellent concentration, excellent concentration, and poor concentration all reached 75.29% and above, and the probability of correctly recognizing excellent concentration was the greatest, gaining 96.80%.
The Integration of Chinese Educational Teaching and Machine Learning Technologies in Cross-Cultural Exchange during the Late Qing and Early Republican Periods
Authors: Fang Xue 
Published: May 2024

Abstract
At the end of the Qing Dynasty, educational reforms precipitated the proliferation of new-style schools, thereby diminishing the prominence of traditional Confucian textbooks in their curricula. This study investigates the pedagogical approaches of Chinese education during the late Qing and early Republic of China periods, focusing on the educational reform movement and the shift from traditional to modern school systems. Utilizing the Scrapy crawling framework, the research involved collecting educational content from 1900 to 1940 to establish a comprehensive corpus. Subsequently, the Word2Vec machine learning algorithm was employed to derive word vectors from this corpus. At the same time, a hybrid model, HS-BTM, which integrates heat, semantic information, and the Biterm Topic Model (BTM), was developed to facilitate a nuanced analysis of semantic shifts in educational content. This analysis was conducted along two dimensions: morphological word semantics and components of teaching content. The findings reveal that the teaching materials contained 702 sets of compound anagrams, and the chemistry textbooks from the period under review featured a significant emphasis on everyday life themes, accounting for 53.25% of the content. By leveraging machine learning techniques, this study effectively charts the evolution of Chinese educational practices and offers valuable insights for the ongoing development of educational strategies.
Construction of Evaluation Indicator System of Festival Tourism Activity Effect Based on FAHP Method
Authors: Lian Jiangong , Liang Dan 
Published: May 2024

Abstract
The prevailing research on festival tourism activities remains limited in scope, and the methodologies employed are often flawed, offering little in terms of enhancing operational efficiency for festival tourism operators. This study advances the traditional Fuzzy Analytic Hierarchy Process (FAHP) by incorporating group decision-making to develop a comprehensive evaluation model termed FAHP-FCE. Furthermore, an evaluative index system for assessing the impact of festival tourism activities has been devised, encompassing economic, social, ecological, and cultural dimensions. This framework was applied in a case study conducted in Tourist City A, utilizing a specifically designed questionnaire to gauge the effectiveness of festival tourism activities within the region. The reliability and validity of the questionnaire are substantiated by a Cronbach’s alpha coefficient of 0.923 and a Kaiser-Meyer-Olkin (KMO) value of 0.925, respectively. The resulting impact scores across the evaluated dimensions—economy (3.96), society (2.87), ecological environment (2.16), and culture (2.62)—reveal that the economic benefits are the most substantial. In contrast, the environmental impacts are the most detrimental in City A. This research not only refines the assessment of environmental impacts but also enriches the methodologies and content of festival tourism effect evaluations, thereby offering fresh perspectives and methods for future inquiries.

Published: May 2024

Objective: The objective of this work is to verify whether these factors influence the hatching of Amazon turtle eggs in this region.

Method: For this, data from reproductive periods during the years 2013 and 2019 were used within the selected areas. Only the depth of the nests was related to the total number of eggs, on both beaches, in both years, and with the number of eggs hatched, only on Praia da Saudade in 2013.

Results and Conclusion: In 2019, Praias da Saudade and Thaís showed differences between incubation temperature, percentage of finer grains in the sand, distance from vegetation to nests and hatching rate. However, none of the evaluated parameters were related to reproductive success. Factors such as the incubation period, the amount of clay in the sand and the percentage of riverine vegetation may also be possible predictors of reproductive success that should be investigated.

Microvascular decompression is effective for oculomotor nerve palsy caused by posterior cerebral artery compression: A case report
Authors: Takeuchi Youhei , Arai Hiroaki , Endo Toshiki , Shibuya Satoshi , Ohtomo Satoru , Endo Hidenori 
Published: May 2024

Background:
Oculomotor nerve palsy is often associated with diabetes mellitus or caused by compression by a cerebral aneurysm. Here, we report a rare case of oculomotor nerve palsy caused by compression by the posterior cerebral artery (PCA).

Case Description:
A 66-year-old woman suddenly developed diplopia and right blepharoptosis. Her symptoms suggested incomplete right oculomotor nerve palsy. Magnetic resonance imaging showed that a sharp curve in the right PCA had compressed the right oculomotor nerve. Microvascular decompression surgery was performed. Intraoperative findings showed that the P2 portion of the PCA had caused an indentation in the oculomotor nerve in the prepontine cistern. The transposition of the PCA with a prosthesis released the pressure. After the operation, her right blepharoptosis gradually improved. She had fully recovered by 48 days after the operation.

Conclusion:
Neurovascular compression (NVC) is recognized as the cause of hemifacial spasms, trigeminal neuralgia, and glossopharyngeal neuralgia. This case report demonstrated that NVC can also cause oculomotor nerve palsy. A high index of clinical suspicion can detect vascular compression of the oculomotor nerve. Prompt diagnosis and appropriate surgical management can achieve clinical improvement.

The analysis of variability of winter soft wheat lines by quantitative traits is presented. The research was conducted in 2020–2023 in the Rostov region. Seven lines of winter soft wheat of the competitive variety trial were taken as an object of research. The Ermak variety was used as a standard. The yields of the lines during the years of study averaged from 9.78 to 10.12 t/ha with an average of 9.76 t/ha in the experiment. Plant height ranged from 85.0 to 115.0 cm. All the lines studied were classified as small- to medium-grained (32.9–45.9 g) in terms of 1000 grain weight. On average for the years of study, the minimum mass of 1000 grains was formed by the line 1638/19 (34.6 g), and the maximum – by the line 1361/19 (43.5 g). The lines had different groups of ripeness according to the indicator of the earing date. The spikelet length varied from 7.3 to 10.0 cm. The highest spikelet length was formed by the line 1361/19 (10.0 cm), the shortest – by the line 1120/19 (7.3 cm). The number of productive stems ranged from 471 to 924 stems/m2. The maximum number of productive stems for the years of the study was formed by the line 1921/20 (758 pcs./m2), the minimum – by the line 1361/19 (689 pcs./m2). The number of grains per plant ranged from 61.6 to 110.6. On average, the highest number of grains per plant was formed by the line 1638/19 (100.6 pcs.), the lowest – 1343/19 (70.4 pcs.). The grain weight per plant averaged 3.54 g and ranged from 2.26 to 4.56 g. The number of grains per ear varied from 28.9 to 51.5 pieces, the maximum number was formed by the lines 1361/19 (42.7 pcs.) and 1638/19 (41.2 pcs.).

Published: May 2024

The income level will influence household spending patterns. In conditions of limited income, low-income or poor households will prioritise allocating their income to buying food. This income will be used to spend on food for survival so it will affect the quantity and quality of household food consumption. Good quality food consumption indicates that nutritional adequacy levels are met. This research analyses the factors influencing household food consumption patterns in East Baturaja District, OKU Regency. This research used a survey method and was carried out in three sub-districts in East Baturaja District, OKU Regency, namely Kemala Raja, Sekar Jaya and Tanjung Baru Villages. The method for determining respondents is random sampling using the Parell et all (1973) formula with the statement if the variance of the total population is unknown, so the best way to determine the sample is to use a percentage of the entire population, namely 2%, 5%, 10%, 20% or 50% of the population. The population is 2126 families, obtained by 2%, namely 42.52 and determined to be 43 families. This research used multiple linear regression models to determine the factors influencing food consumption patterns using multiple linear analyses. Based on the research results, it can be concluded that the factors that influence household food consumption patterns in East Baturaja District, OKU Regency, are income (X1), number of family members (X2), age (X3), and education level (X4). The variable that has the most influence on household food consumption patterns in East Baturaja District, OKU Regency, is the income level variable (X1). Simultaneously or together, the income variable (X1), number of family members (X2), age (X3), and education level (X4) has a significant influence. R2 showed this with a value of 97.9%.
