Intramuscular hemangioma (IMH) is a diffuse growth hemangioma located in the striated muscle, which is often overlooked due to its rarity. Intramuscular hemangioma (IMH) is a diffuse growth hemangioma located in the striated muscle, which is often overlooked due to its rarity. This patent pertains to the integration of electroacupuncture with electrothermotherapy. By introducing electrical signals into the electroacupuncture system, electromagnetic heat is produced. This heat leads to the electrolysis and thermal destruction of tumor cells, enabling targeted and precise cancer treatment. Furthermore, the patent offers a theoretical foundation for exploring the distribution of electrical signals and the associated heat in arm muscles, ensuring accurate treatment. To enable subsequent experimental validation, this patent integrates human anatomy and histological structure theory. The arm's geometric structure was derived from segmentation, reconstruction, and substantiation based on a digital human image dataset. Using the COMSOL Multiphysics 5.5 software, a semi-detailed finite element model was developed for the numerical simulation of electrothermotherapy. Within a time domain setting, a carrier signal of 1 MHz and 22 V was introduced to assess the distribution of electrical signals and the associated heat in the arm muscle. Electrical signals, electromagnetic heat, and tissue necrosis primarily concentrate in a spherical region within 10 mm of the exposed electroacupuncture tip, with the maximum coupling temperature reaching 250 °C at the tip. Time domain analysis revealed that the coupling temperature can rise within 1 min, sufficiently to cause complete tissue damage, with the tissue necrosis ratio reaching 100% in the same timeframe. While the coupling temperature continues to rise over time, the increment is modest. After 5 min, there is negligible temperature change, and once the tissue necrosis ratio reaches 100%, it remains consistent. In the precision tumor treatment system utilizing electrothermotherapy, factors, such as the magnitude of the injected electrical signal, placement of the electroacupuncture tip, and treatment duration play a crucial role in the treatment's accuracy. This model delves into the treatment of intramuscular hemangiomas using electroacupuncture electrothermotherapy from two perspectives: spatial and temporal domains. It provides a theoretical foundation for precise electrothermotherapy in cancer treatment. In the precise tumor treatment system with electrothermotherapy, the size of the injected electrical signal, the position of the electroacupuncture tip and the treatment duration all have a significant impact on the precise treatment. This model is used to analyzes the treatment of intramuscular hemangiomas with electroacupuncture electrothermotherapy from two aspects: spatial and temporal domains, providing a theoretical basis for the precise electrothermotherapy for cancer. null

China is rich in mineral resources with a complete range of types. Currently, 163 kinds of minerals have been found, and 149 kinds of minerals with Proven reserves, including 7 kinds of energy minerals, 54 kinds of metal minerals, and 86 kinds of non-metallic minerals. Ore particles can undergo various collisions during mining and transportation. Because particle collision behavior can greatly affect particle size and particle properties during the final application, it can also lead to the generation of a large amount of dust during processing and transportation, seriously affecting environmental quality. Therefore, exploring the collision performance of particle collisions is very important. This test bench can compensate for the shortcomings of existing particle collision measurement technologies, by measuring the motion trajectory after collision between particles, as well as the collision force between particles and metal plates, as well as the motion trajectory after collision. The test bench has the advantages of a simple structure, a small footprint, diverse functions, and stable operation. This test bench can be used for measuring the collision force and post-collision motion trajectory of block particles and has broad practicality and strong innovation.

Among the various statistical measures, Root Mean Square Error (RMSE), Mean absolute Percentage Error (MAPE), and R-squared (Coefficient of determination) are the most widely used methods. The significance of the R square approach in the medical field was extensively discussed in the current review. Furthermore, we compared a number of statistical metrics for potential applications in the treatment of various disorders. In addition, the pertinent patents of R square for the consequences of testosterone and the enzymes aspartate dehydrogenase (AST) and alanine transaminase (ALT) on Polycystic Ovary Syndrome (PCOS) treated patients have been developed. We study in this paper the detailed comparative study on the biological system using RMSE, MAPE, and R Squared, which consists of 29 PCOS-influenced women against 20 healthy women and followed by the obesity verification model over the Sprague Dawley rats. R Square provides the best results among all mathematical regression analytical methods in PCOS-influenced patients. In this study, we provide the strong conclusion that aspartate dehydrogenase (AST) with testosterone treated on PCOS influenced women to have a greater chance of getting affected by Non-alcoholic fatty liver disease (NAFLD) rather than alanine transaminase (ALT) with testosterone- treated patients. Furthermore, this study extends their mathematical regression analysis through R squared for the obesity verification over rat model. It confirms that letrozole-treated rats are inhibited in obese compared with control rats, which results in a chance of NAFLD. Therefore, AST combined with testosterone creates a major chance for liver dysfunction.

One of the main directions of modern technology in the field of precision machining is high-speed operation. The spindle system is commonly utilized in this kind of operation, and the electric spindle is the main preference among high-speed machine tool spindles. High-speed electric spindle vibration characteristics affect the machining accuracy of the machine tool and the quality of the workpiece, so the research on high-speed electric spindle vibration characteristics has important engineering practical significance. The research status of high-speed electrospindle at home and abroad has been summarized in this paper. Combined with the patents related to the dynamics modelling of electrospindle, the research on the dynamics modelling of high-speed electrospindle is analyzed. On this basis, the computational and analytical methods for the vibration modelling of the electrospindle, including the transfer matrix method and the finite element method, are investigated, the theoretical foundations of these methods are discussed in depth, and the advantages and disadvantages of the methods are evaluated. The applicability and limitations of the two methods are also compared. The analysis has shown that the current research on the vibration characteristics of highspeed electrospindle is mainly based on mechanical modal analysis and electromagnetic analysis. At present, the dynamic modeling of the electrospindle mainly includes bearing modeling, shaft bearing modeling, spindle-case modeling, electrospindle electromechanical coupling modeling, electrospindle thermal coupling modeling, etc. The correctness of the modelling theory is verified through experimental and simulation results. Although these models tend to be perfected, they are still insufficient in the case of multiple influencing factors coupling and need further development. Finally, through the analysis of the patent and dynamic characteristics related to the high-speed electric spindle, thermal deformation, magnetic tension, material, and other factors should be considered comprehensively, and these factors should be coupled to establish an overall dynamics model for the vibration characteristics analysis. The dynamic modelling, vibration modelling method, and vibration characteristics of the high-speed electric spindle have been summarized in this study, and the outlook is presented.

The prediction of the stock price is considered to be one of the most fascinating and important research and patent topics in the financial sector. Making more accurate predictions is a difficult and significant task because the financial industry supports investors and the national economy. The DWM is used to adjust the connection weights and biases to enhance prediction precision and convergence rate. DWM was proposed as a method to reduce system error by changing the weights of various levels. The methods for predictable changes in weight were provided together with the computational difficulty. An extreme learning machine (ELM) is a fast-learning method for training a singlehidden layer neural network (SLFN). However, the model's learning process is ineffective or incomplete due to the randomly chosen weights and biases of the input's hidden layers. Hence, this article presents a deterministic weight modification (DWM) based ELM called DWM-ELM for predicting the stock price. The calculated results showed that DWM-ELM had the best predictive performance, with RMSE (root mean square error) of 0.0096, MAE (mean absolute error) of 0.0563, 0.0428, MAPE (mean absolute percentage error) of 1.7045, and DS (Directional Symmetry) of 89.34. The experimental results showed that, in comparison to other well-known prediction algorithms, the suggested DWM+ELM prediction model offers better prediction performance. The experimental results showed that, in comparison to other well-known prediction algorithms, the suggested DWM+ELM prediction model offers better prediction performance.

Application of irrigation water to various crops in the command area on the basis of daily crop water requirement considering water holding capacity of various irrigated soils is vital aspect of irrigation management. Considering importance of irrigation scheduling present version of FAO CROPWAT 8.0 is very much useful tool, as it gives crop water requirement and irrigation schedule on the basis of climatological and physiographic factors of the command area. In this study CROPWAT 8.0 model is used for calculation of crop water requirement and thus irrigation requirement which can be used for scheduling the irrigation for command area of Pawale irrigation project. Pawale irrigation project is located in Thane district of Maharashtra India. Nineteen years of climatic data is used for the analysis, considering seven crops to calculate the crop water and net irrigation requirement for kharif and rabi season. The result indicates that crop wise and season wise variation of crop water requirement is from 2.5 to 1055.1 mm and net irrigation requirement for the year is 618.6mm. It’s also observed that rice requires more water from initial stage upto development stage as compared to other crops considered in this study. The results indicates that evapotranspiration has greater impact on crop water requirement and net irrigation requirement because in both the cases, the increase or decrease of ETo will affect the crops and their water requirement. The sensitivity analysis for different type of soils is also carried out for groundnut. The result indicates that, apart from crop, the water holding capacity of soil is very important characteristic for irrigation scheduling. It is seen that. 9 rotations are required for red sandy soil as compared to 6 rotations and 4 rotations to red sandy loamy soil and black clay soil respectively.

It is a moral duty to act in a way that considers the welfare of both people and the planet. When constructing, two factors should be considered: the sustainability of the developmentrelated workforce and the state of the world after construction. Many experts have achieved notable reforms in the civil infrastructure systems (CIS) sector in the past. However, additive manufacturing (AM) does not seem to be properly understood by the CIS business. This survey examines how all the fundamental components used by AM in CIS, such as metals, cement, and polymers, are utilized. The goal of this study is to foster AM innovation, particularly in the CIS, and to provide an overview of AM development from 2011 to 2022. Additionally, the various AM techniques used to construct the aforementioned structures are presented. The audit research suggests that AM might be beneficial in the CIS industry due to the fact that residences, additions, and seats were constructed using this technique. Photos of the constructed structures are also included to enhance the reader's understanding. It is generally assumed that implementing AM tactics in the CIS industry may reduce material consumption, expedite the development process, and enhance employee safety. Due to the limited amount of available research, further investigation into polymer printing and metal printing is recommended.
考虑到人类和地球的福祉是一种道德责任。在施工时，应考虑两个因素：与发展相关的劳动力的可持续性和施工后的世界状况。过去，许多专家在民用基础设施系统（CIS）领域取得了显著的改革成果。然而，增材制造（AM）似乎并没有得到独联体企业的正确理解。本调查研究了如何利用 CIS 中 AM 使用的所有基本组件，如金属、水泥和聚合物。这项研究的目的是促进 AM 创新，特别是在独联体国家，并提供 2011 年至 2022 年 AM 发展概况。此外，还介绍了用于建造上述结构的各种 AM 技术。审计研究表明，由于住宅、加建物和座椅都是使用这种技术建造的，因此自动机械化可能对独联体工业有益。为了加深读者的理解，还附上了所建结构的照片。一般认为，在 CIS 行业实施 AM 技术可以减少材料消耗、加快开发过程并提高员工安全。由于现有研究数量有限，建议进一步调查聚合物打印和金属打印。

Introduction: Land use and Land cover (LULC) are now major worldwide issues. The need for land is growing due to urbanisation and industrialisation, thus to meet this need, forest and vegetation land are transformed to open land that is either utilised for colonisation of urban areas or industrial usage. Patents are done on the calculation of LST. Introduction: Land use and Land cover (LULC) are now major worldwide issues. The need for land is growing due to urbanisation and industrialisation, thus to meet this need, forest and vegetation land are transformed to open land that is either utilised for colonisation of urban areas or industrial usage. Patents are done on the calculation of LST. background: The LULC classification is performed based on four classes Bare land, Built-up, Vegetation and Waterbodies. Method: The study aims to provide a detailed analysis of land and temperature change with variation in Normalized difference vegetation index (NDVI) and normalized difference build-up index (NDBI) for the study area using a geospatial technique. The LULC classification is performed based on four classes which are Bare land, Built-up, Vegetation, and Waterbodies from the year 2000 to 2020. The classified data is further used to extract the Land Surface Temperature (LST) data from the thermal band to generate LST maps. The NDVI and NDBI maps are also generated using the land sat imageries. From the above-mentionedanalysis, it is found that Nagpur city temperature has risen by 3.67 °C in two decades. Whereas, LULC results show that bare land and vegetation decreased by 11.88% and 14.93% respectively, while an increase is seen for built-up and water bodies by 25.62% and 0.19% respectively. objective: The classified data is further used to extract the LST data from thermal band to generate LST maps. Result: Regression analysis between temperature and NDVI, NDBI shows that temperature and NDVI have a negation relation and NDBI has a positive relation with temperature (Pearson’s r: between -0.89 to -0.81and between 0.90 to 0.81respectively) for both the years. The increased temperature is a result of urbanization in the study area. The study reveals that for assessment of LULC and LST with the incorporation of GIS and Remote sensing can be effective and swift. method: The NDVI and NDBI maps are also generated using the land sat imageries. From the analysis of above mentioned it is found that Nagpur city temperature is raised by 3.67 °C in two decades. Conclusion: This study recommends that policymakers develop policies that should minimize the transition of different classes and check the outcome of industries and the temperature of the surroundings. conclusion: The increase temperature is a result of urbanization for study area.
