Published: January 2024

Currently, the data management of power enterprises faces the need to analyze data sources from multiple places. However, traditional multi-source data fabric systems have problems such as low analysis efficiency and high error rates, which brings great inconvenience to the data analysis of power enterprises. In order to improve the accuracy and efficiency of data analysis in data structure systems, the intelligent system architecture is applied to the construction of source data structure systems. The main modules are data collection, data matching, data integration, and data analysis. This article uses simulated annealing genetic algorithm to perform high-performance calculations on system timing data, thus achieving data matching. This article conducted data level data integration, feature level data integration, and decision level data integration. The access survey method was used to analyze the current data management problems faced by power companies. The evaluation and analysis of general multi-source data fabric systems and multi-source data fabric systems based on intelligent system architecture were conducted using the evaluation panel evaluation method. The analysis results showed that the operational convenience of the multi-source data fabric system based on intelligent system architecture could reach 60%–80%, which greatly improved compared to general multi-source data fabric systems; the information sharing of multi-source data fabric systems based on intelligent system architecture was greatly improved; the data processing efficiency of general multi-source data fabric systems was much lower than that of multi-source data fabric systems based on intelligent system architecture; however, the symmetry of data collection and matching in the multi-source data fabric system based on intelligent system architecture was slightly insufficient, and further improvement was still needed. In order to benefit more power companies through the intelligent system architecture based multi-source data fabric system, it was necessary to strengthen the management of data collection and matching symmetry.

This proves that the task scheduling of the cloud platform is more balanced, and indirectly proves the accuracy of the algorithm’s clustering effect.
A multi-granularity ensemble algorithm for medical image classification based on broad learning system
Authors: Li Keyuan , Zhang Qinghua , Xie Qin , Huang Shuaishuai
Published: January 2024

Medical image classification is an essential task in the fields of computer-aided diagnosis and medical image analysis. In recent years, researchers have made extensive work on medical image classification by computer vision techniques. However, most of the current work is based on deep learning methods, which still suffer from expensive hardware resources, long time consuming and a lot of parameters to be optimized. In this paper, a multi-granularity ensemble algorithm for medical image classification based on broad learning system is proposed, which is an end-to-end lightweight model. On the one hand, the proposed method is designed to address the problem of weak image feature learning ability of broad learning system. The convolution module with fixed weights based on transfer learning is introduced as a feature extractor to extract fusion features of medical images. On the other hand, the multi-granularity ensemble framework is proposed, which learn the fusion features of medical images from fine-grained to coarse-grained respectively, and the prediction results at different granularity levels are integrated by ensemble learning. In this way, the bottom local features can be sufficiently considered, while the global features can also be taken into account. The experimental results show that on the MedMNIST dataset (containing 10 sub-datasets), the proposed method can shorten the training time by tens of times while having similar accuracy to deep convolutional neural networks. On the ChestXRay2017 dataset, the proposed method can achieve an accuracy of 92.5%, and the training time is also significantly better than other methods.

Enhanced group decision-making through an intelligent algorithmic approach for multiple-attribute credit evaluation with 2-tuple linguistic neutrosophic sets
Authors: Mao Cui
Published: January 2024

With the development of the internet economy, e-commerce has rapidly risen, and a large number of small and micro e-commerce enterprises have emerged. However, these enterprises have low financial information transparency, small scale, and high development uncertainty. Therefore, combining the characteristics of the internet economy, it is of great significance to dynamically evaluate credit risk. This not only helps to enhance the quality and rationality of credit risk evaluation results, but also helps to improve financing efficiency and reduce financing risks. The credit evaluation for small and micro enterprises is a multiple-attribute group decision-making (MAGDM). Recently, the TODIM (an acronym in Portuguese of interactive and multicriteria decision making) and TOPSIS method has been inaugurated to cope with MAGDM issues. The 2-tuple linguistic neutrosophic sets (2TLNSs) are inaugurated as an effective tool for characterizing uncertain information during the credit evaluation for small and micro enterprises. In this paper, the 2-tuple linguistic neutrosophic TODIM-TOPSIS (2TLNN-TODIM-TOPSIS) method is inaugurated to solve the MAGDM under 2TLNSs. Finally, a numerical case study for credit evaluation for small and micro enterprises is inaugurated to confirm the proposed method. The prime contribution of this paper are outlined: (1) The information entropy based on score function and accuracy function are built on the 2TLNSs to obtain weight information; (2) an integrated the 2-tuple linguistic neutrosophic TODIM-TOPSIS (2TLNN-TODIM-TOPSIS) method is established to cope with MAGDM; (3) An illustrative example for credit evaluation for small and micro enterprises has accomplished to illustrate the 2TLNN-TODIM-TOPSIS; (4) some comparative analysis are employed to verify the 2TLNN-TODIM-TOPSIS method.
ArMT-TNN: Enhancing natural language understanding performance through hard parameter multitask learning in Arabic
Authors: Alkhathlan Ali , Alomar Khalid
Published: January 2024

Multitask learning (MTL) is a machine learning paradigm where a single model is trained to perform several tasks simultaneously. Despite the considerable amount of research on MTL, the majority of it has been centered around English language, while other language such as Arabic have not received as much attention. Most existing Arabic NLP techniques concentrate on single or multitask learning, sharing just a limited number of tasks, between two or three tasks. To address this gap, we present ArMT-TNN, an Arabic Multi-Task Learning using Transformer Neural Network, designed for Arabic natural language understanding (ANLU) tasks. Our approach involves sharing learned information between eight ANLU tasks, allowing for a single model to solve all of them. We achieve this by fine-tuning all tasks simultaneously and using multiple pre-trained Bidirectional Transformer language models, like BERT, that are specifically designed for Arabic language processing. Additionally, we explore the effectiveness of various Arabic language models (LMs) that have been pre-trained on different types of Arabic text, such as Modern Standard Arabic (MSA) and Arabic dialects. Our approach demonstrated outstanding performance compared to all current models on four test sets within the ALUE benchmark, namely MQ2Q, OOLD, SVREG, and SEC, by margins of 3.9%, 3.8%, 10.1%, and 3.7%, respectively. Nonetheless, our approach did not perform as well on the remaining tasks due to the negative transfer of knowledge. This finding highlights the importance of carefully selecting tasks when constructing a benchmark. Our experiments also show that LMs which were pretrained on text types that differ from the text type used for finetuned tasks can still perform well.

Published: January 2024

What qualities are needed by statisticians to achieve top leadership positions in academia, business, industry and government? Five leaders from statistical societies, national and international statistical offices, and academia share their experiences. They respond to five specific questions. Firstly, is leadership just needed by top management or do all statisticians have a role? If so, what is it? Secondly, do statisticians naturally make good leaders? What new skills do they need to acquire? What skills advantages do they have? Thirdly, the panel consider the question: did you work for people who were not good leaders? How did they fall short? What good role models did panellists have? And then, is it harder for women, and for other under-represented groups?

And finally they were asked: what message do you have for young statisticians aspiring to leadership roles?

Authors:   Korean Academy of Cardiorespiratory Physical Therapy, Jung Dae-In , Lee Han-Gyeol
Published: January 2024

Purpose: This study aimed to investigate the effects of mask type and wearing during class on concentration and respiratory function.
Methods: A total of 90 college students were included in this study. These participants were divided into three groups: group 1, no mask (n=30); group 2, dental mask (n=30), and group 3, KF94 mask (n=30). Respiratory function tests were performed in all groups, as well concentration ability test before and after 2 hours of class. All data were analyzed using SPSS window version 22.0.
Results: The difference in respiratory function according to the mask type and wearing was statistically significant in FVC, FEV1, and concentration ability except for FEV1/FVC (p<.05). As a result of post-hoc analysis, FVC, FEV1, and concentration ability values were significantly lower in the group not wearing a mask (p<.05). FVC, FEV1, and concentration ability were significantly lower when wearing KF94 than when wearing a dental mask (p<.05).
Conclusion: It was found that the more masks with a high blocking grade, the greater the decrease in concentration. Therefore, it is recommended not to wear a mask or wear a low-blocking-grade mask in order to maintain concentration on the class, except for cases with underlying diseases or low health risks in conducting face-to-face classes in the future.

Published: January 2024

The study investigates the interaction between mind and matter by exploring correlations between psychological behaviour with a physical system. Psychological data, acquired during task performance, and physical variables from a random number generator are combined into matrices for joint analysis. The research aims to examine the statistical distribution of matrices generated in experimental sessions compared to control sessions.

A total of 726 participants from over 50 countries engaged in an online game via touchscreen device (mobile or tablet), yielding data from 10.964 studies. Random number generators Random.org (5.330 studies) and Mersenne twister (5.634 studies) were utilized, resulting in the analysis of 10.525.440 psychological variables and 21.050.880 random values as physical variables.

Random number generator data were analysed separately. The analysis using Random.org indicated statistically significant differences between experimental and control sessions when employing a matrix with 4096 cells (64x64). The Welch’s T-test yielded a value of 3,811, with a corresponding p-value of 0,0001. The achieved power was high at 94%, while the effect size reached 0,084, above the required minimum meaningful effect size of 0,071. The analysis using Mersenne Twister did not exhibit statistically significant differences concerning the same matrix (64x64). The Welch’s T-test resulted in a value of 1,813, with a corresponding p-value of 0,069. The achieved power stood at 67%, while the effect size attained was 0,040, falling short of the minimum meaningful effect size required which was 0,071.

Ground - penetrating radar (GPR), a modern geophysical method, is used to study the shallow structure below the ground, based on the principle of electromagnetic wave generation and reception in the high frequency range of 10 - 3000 MHz. The received signal could be presented in the form of images, similar to the ultrasound method in medicine, to study the shallow geological structure below the ground. In order for the GPR cross - section to accurately reflect the environment below the ground, data processing always plays a very important role, in order to eliminate horizontal noise, permanent noise, etc., which often blur or obscure objects of interest. Many signal processing methods have been studied and applied, but the improvement of processing methods has always received much attention from scientists. This paper presented the theoretical basis and how to apply the Karhunen - Loeve filter to the model and practical GPR cross - section, in order to remove the standing and horizontal noises. Experimental results on the theoretical and practical models showed that the interested signals were highlighted and some noise forms were blurred. This initial success would be a promise to develop the problem of automatic processing and identification in the GPR method of the research team.

Objective: To evaluate the effect of a supplementary feeding (with different crude protein (CP) levels) in the yield and growth performance and meat characteristics of hair lambs grazed on Tanzania grass.
Design/Methodology/Approach: A 120-d-1 experiment was conducted; it included four treatments and seven replications in a completely randomized design. Twenty-eight hair lambs (22.6 ± 1.6 kg LW) were allowed to graze on Tanzania grass (Panicum maximum) and were provided concentrate feeds (with 10, 12, 14, and 16% crude protein). The aim was to assess the effects of the latter food on growth, carcass characteristics, and meat quality.
Results: Compared with the lambs fed with 10, 12, and 14% CP, the heaviest carcasses (P<0.05) were obtained from lambs fed with 16% CP. The percentage of crude protein and fat of the biceps femoris linearly increased (P<0.05) as the CP percentage increased in the concentrate feed. Meat color, water retention capacity, and cutting force were not impacted by the CP percentage of the concentrate feeds. Compared with the lambs fed with 10, 12, and 14%, the lowest palmitic acid percentage and the highest oleic acid percentage were found in the meat of lambs fed with 16% CP.
Study Limitations/Implications: A high area was selected to avoid excessive rain.
Findings/Conclusions: Compared with the lambs fed with 10, 12, and 14% CP, the lambs grazed on Tanzania grass and supplemented with 16% CP grew more, recorded a higher carcass yield, and their meat had a better unsaturated fatty acids ratio.

Published: January 2024

Objective: To evaluate the plant selection of the diet of goats during the dry season and the chemical composition of the said plants in three microregions of the Comarca Lagunera, Mexico.
Design/Methodology/Approach: Three microregions were identified within the Comarca Lagunera: 1) mountain slope, 2) plain, and 3) cultivation areas. The selection of the goat diet, the availability of forage, and the nutritional composition (CP, EE, DNF, AFD, NFC, TDN, and NEl) of plant species and strata were evaluated in the three microregions.
Results: The shrubs and herbaceous in the Comarca Lagunera had the highest forage availability and a better nutritional profile during winter. On the one hand, these plant strata had an adequate protein content. On the other hand, the overall energy content reached <1 Mcal kg-1 DM.
Study Limitations/Implications: The plant strata have an adequate protein content; however, the energy content is not enough and limits growth. Consequently, supplementation programs for grazing dairy goats in the Comarca Lagunera must include sources of energy.
Findings/Conclusions: Regardless of the microregion, the energy content of the species consumed by grazing dairy goats in the Comarca Lagunera is low.

El objetivo fue conocer de fuentes primarias las causas que orillan a los tianguistas a la informalidad, teniendo como caso de estudio a los tianguistas en la Ciudad de León de los Aldama. Se parte de la hipótesis de que la condición de informalidad de los tianguistas no solo obedece a problemas estructurales, sino también a estrategias de sobrevivencia de algunos grupos sociales que sortean las inequidades estructurales e incluso logran cierta movilidad social aprovechando las lagunas normativas y fiscales en la economía formal. Para tal efecto, metodológicamente el acercamiento se logró a través de entrevistas y una encuesta con los actores económicos, quienes dieron información de primera mano sobre las causas y estrategias hacia la informalidad. Además de analizar con mayor certeza el tamaño del fenómeno, en el aspecto cualitativo de la investigación se avanzó en la comprensión de aspectos sociales y económicos de estos comerciantes en la informalidad de los tianguis en León, lo cual se logró a partir de una encuesta aplicada a una muestra representativa de los más de 36,000 comerciantes que se instalan en los 224 tianguis en León, Guanajuato. En los resultados, se conocieron aspectos sociales y económicos con los cuales es posible corroborar la hipótesis, esto es, la decisión de ser tianguista no solo pasa por condiciones de desigualdad que devienen de aspectos estructurales; sino que también es una estrategia de sobrevivencia ante dichas inequidades estructurales.

Menurut WHO (2013), berkisar 20% dan 89% ibu hamil mengalami kejadian anemia dengan menetapkan Hemoglobin 11 g% sebagai dasarnya. Sekitar 70% ibu hamil di Indonesia mengalami anemia akibat kekurangan gizi terutama zat besi. Kekurangan zat besi pada ibu hamil dapat meningkatkan resiko kematian pada saat melahirkan, bayi lahir dengan BBLR, keguguran dan resiko bayi lahir premature. Vitamin C dapat meningkatkan penyerapan besi non heme sebesar empat kali lipat dan dengan jumlah 200 mg akan meningkatkan absorpsi besi sedikitnya 30% (Goodman, 2008). Buah jambu biji mengandung asam askorbat2 kali lipat dari jeruk yaitu sekitar 87 mg/100 gram jambu biji. Tanaman jambu biji mudah ditemukan dan lebih ekonomis, sehingga hal tersebut menjadi salah satu alasan pemilihan bahan menjadi produk untuk intervensi. Selain itu, jambu biji merah juga kaya akan vitamin dan mineral. Kandungan vitamin C jambu biji merah dapat meningkatkan kualitas absorbsi zat besi dalam tubuh sehingga kadar hemoglobin ibu hamil akan meningkat. Kata Kunci : Jambu Biji Merah, Kadar Hemoglobin, Ibu Hamil
Women and Finance-Specific Human Capital: Impact of Gender Role Attitudes
Authors: Smith Brianne , Finke Michael
Published: January 2024

The benefits and costs of investing in finance-specific human capital are affected by subjective attitudes about the expected improvement in consumption from higher-quality financial decisions and the expected psychic costs of investing. This study investigates how gender role attitudes of women predict their acquisition of finance-specific human capital. Results indicate that women with the most traditional gender role attitudes are less financially literate than women with non-traditional gender role attitudes and men. Gender role attitudes formed early in life explain differences in financial literacy between men and women observed in prior studies. Multivariate analyses that control for attained human capital suggest that traditional gender role attitudes affect finance-specific human capital investment and investment in formal education. Women with traditional gender role attitudes are the least knowledgeable and have the lowest confidence in applying their financial knowledge.

In this study, previously obtained cobalancing numbers are considered from a different perspective, and the properties of the numbers are re-examined. The main purpose is to change the recurrence relation of cobalancing numbers and calculate some relations and properties in a more diverse and easier way. The reason that led us to this method is that the recurrence relation of cobalancing numbers has a second-order but non-homogeneous difference equations. Thus, it will be much easier to find the Binet formula, generating function, sum formulas, and many other relations with a sequence that is homogeneous and has a third-degree recurrence relation. Also some identities that have not been found before in the sequence are also included in this study.
Energy Subsidies and Sustainability: A Comparative Analysis of India and China
Authors: Sakib S M Nazmuz
Published: January 2024

Purpose: Energy subsidies significantly impact a nation's energy landscape, with the potential to enhance energy access, affordability, and security. However, when these subsidies are directed at fossil fuels, they can disrupt markets and impede sustainability goals. This paper's primary purpose is to compare energy subsidies in India and China, two rapidly growing and densely populated economies. It seeks to comprehend how these subsidies influence their respective energy sectors, economic trajectories, and sustainability objectives. Methods: The study employs a policy and economic perspective, relying on a combination of data analysis, case studies, and policy evaluations. This methodological approach allows us to investigate the operation and objectives of energy subsidy programs in India and China. Results and Conclusion: In this comparative analysis, we find that India and China share common policy goals related to energy access, affordability, security, and sustainability. However, their approaches differ significantly. India places a strong emphasis on cleaner cooking fuels, while China prioritizes market-based pricing and leadership in adopting renewable energy sources. Despite these variations, both countries grapple with fiscal burdens, market distortions, and environmental challenges due to subsidies for fossil fuels. Policy Implications: Based on the study's findings, a series of policy recommendations emerge. These include the need to refine subsidy targeting, expedite the adoption of clean energy sources, encourage market-driven pricing mechanisms, enhance environmental regulations, and continue playing active roles in international climate negotiations. Furthermore, there is a pressing necessity to reevaluate and adjust energy subsidies to ensure their alignment with broader sustainable development goals.

El compostaje con lombrices rojas californianas es una técnica eficaz para la valorización de residuos orgánicos, mejorando los procesos de compostaje y aumentando su eficiencia. El objetivo de la investigación fue evaluar el comportamiento productivo y reproductivo de la lombriz roja californiana Eisenia foetida en compostaje con residuos orgánicos. Los tratamientos fueron T1:90% de tierra agrícola +10% de cartón de cubetas de huevos. T2:80% estiércol bovino+10% de tierra agrícola+10% de cartón. T3:80% residuos caseros +10% de tierra agrícola+10% de cartón, y T4:80% residuos agrícolas +10% de tierra agrícola +10% de cartón. Se utilizó un DCA y, se emplearon 320 lombrices en etapa sub-adulta. Se evaluó la Biomasa de lombrices, degradación del sustrato (%), producción de lombriz (densidad), tasa de crecimiento, parámetros reproductivos, producción de cocones y morfometría. La degradación del sustrato producido por las lombrices tuvo 39,99% de humus con el 80% estiércol bovino+ 10% hojarasca +10% de cartón (T2). La producción total de lombriz tuvo incrementos equivalentes en los T1 (259) y T2 (243,50). La madurez sexual de las sub adultas en todos los tratamientos alcanzo a los 21 días con su clitelo desarrollado. En la producción de cocones, los T1 y T2 depositaron mayor cantidad a los 45 y 60 días (119; 80) y (133; 96). La mayor fertilidad tuvo T2 (92%) y superó con 4 lombrices por cocón. Las repuestas reproductivas y la morfometría se encuentran estrechamente relacionadas, las lombrices podrán destinar cierta proporción de lo consumido y asimilado a la parte reproductiva como comportamiento propiamente biológico de conservación de su especie.

El presente trabajo de investigación, está centrado en el impacto ambiental que puede ocasionar las baterías convencionales en comparación de las baterías de flujo. Haciendo una breve comparación entre las diferentes tecnológicas y centrándose en la parte técnica de estos dos elementos como caso de estudio. El objetivo se centra en realizar una comparación técnica de la eficiencia de las baterías convencionales y de flujo por medio de un análisis de las características para determinar los costos/beneficio y el impacto ambiental. En la parte metodológica se aplica una investigación básica no experimental, exploratoria- transversal, con un enfoque cualitativo y cuantitativo, y apoyada en un estudio documental, en la que se analiza variables como en la parte económica, costos de implementación, impacto ambiental, características técnicas y costos de implementación. Obteniendo como resultados que las baterías de flujo (vanadio- vanadio, zinc-bromo, vanadio- bromo), presentan mayor eficiencia ya sea por su rendimiento, sistema de instalación, impacto ambiental y costos de adquisición, contado con una vida útil aproximado de 20 años y profundidad de descarga al 100%, operación en condiciones altas, con una escalabilidad llegando a potencias en MW y baja toxicidad; a comparación de las baterías convencionales que a pesar de ser las más usadas, presentan limitaciones a gran escala debido a los límites de ciclo de 2000 ciclos/vida útil y tendiendo una alta toxicidad por los componentes químicos. Es importante implementar tecnologías de almacenamiento que sean resilientes con el medio ambiente y no solo pensando en el costo- beneficio

Los productores por el desconocimiento de las propiedades del mucílago de cacao no aprovechan sus bondades. Es por ello, que la presente investigación tuvo como objetivo evaluar el aprovechamiento de mucílago de cacao (T. cacao) con mora (R. ulmifolius) arándano (O. microcarpus) y frambuesa (R. idaeus) en la elaboración de un néctar. Para ello, se aplicó un Diseño Completamente al Azar con arreglo factorial A*B (factor A= Tipo de frutos rojos) y (Factor B= Variedad de mucílago de cacao). En cuanto a los resultados de los análisis fisicoquímicos, se determinó diferencia significativa en pH (3,18 – 3,30); °Brix (13,50 – 14,47 %) y polifenoles totales (370 a 633 mg ac. gálico/ml). Mientras que, las variables acidez titulable y densidad no presentaron diferencia significativa. Por otro lado, el T1= 20 % de pulpa de mora + 25 % mucílago de cacao Nacional 25% presentó mayor valoración en las categorías sensoriales: aroma, sabor, aceptabilidad y el T3= 20 % pulpa de arándano + 25 % mucílago de cacao Nacional presentó una mejor coloración. Cabe mencionar que el T3, obtuvo resultados microbiológicos dentro de los límites permisibles por la norma técnica ecuatoriana NTE INEN 2337:2008. De esta forma, se concluye que la utilización del 25 % de mucílago de cacao nacional puede empleado en la elaboración de un néctar de frutos rojos, permitiendo obtener un producto con excelentes características y mayor aceptabilidad, además, un producto inocuo y apto para el consumo humano.
