Comparison of three large language models as middle school math tutoring assistants
Authors: Ramanathan Hamsini , Palaniappan Ramanathan
Published: May 2024

Middle school math forms the basis for advanced mathematical courses leading up to the university level. Large language models (LLMs) have the potential to power next-generation educational technologies, acting as digital tutors to students. The main objective of this study was to determine whether LLMs like ChatGPT, Bard, and Llama 2 can serve as reliable middle school math tutoring assistants on three tutoring tasks: hint generation, comprehensive solution, and exercise creation. Our first hypothesis was that ChatGPT would perform better in completing all three tutoring tasks than Bard and Llama 2 due to its largest model size (175 billion parameters). Our second hypothesis was that Bard would perform better than Llama 2 in generating comprehensive correct solutions due to its relatively higher model size (137 billion parameters) than Llama 2 (70 billion parameters). We curated medium-difficulty, word-based middle school math problems on algebra, number theory, and counting/probability from The Art of Problem Solving and Khan Academy. A human tutor evaluated the LLMs' performance on each tutoring task. Contrary to our first hypothesis, results showed that ChatGPT didn't perform uniformly better than Bard and Llama 2 on all the tasks. ChatGPT outperformed both Bard and Llama 2 only in the comprehensive solution task. Bard didn't perform better than Llama 2 in the comprehensive solution task which does not support our second hypothesis. We conclude that middle school math teachers can use a combination of ChatGPT, Bard, and Llama 2 as assistants based on the specific tutoring task.

Four clinical vancomycin susceptible Staphylococcus aureus (VSSA) isolates were subjected to selection for the vancomycin-intermediate S. aureus (VISA) phenotype using increasing concentrations of vancomycin. The vancomycin MIC achieved for VISA strains was 7 µg/mL. Population analysis profiles of the bacteria revealed that almost 100% of population growing at 4 µg/mL of vancomycin while some subpopulations were found to be resistant to concentrations ranging from 6 to 9 µg/mL of vancomycin. The results correlated with the AUC ratios for VISA, which ranged from 3.02-3.3 in this study. In the absence of vancomycin in the assay buffer, all the laboratory-derived VISA strains exhibited reduced whole cell autolysis compared to that of their VSSA counterparts. Examination of cell wall morphologies revealed that almost all the laboratory-derived VISA strains had thicker and rougher cell wall surfaces compared to their parental strains. Vancomycin had no remarkable effects on the thickness and roughness of the cell wall of all the laboratory-derived VISA derivatives.

Published: May 2024

Stress is a common and often unavoidable aspect of daily life that can negatively impact the autonomic nervous system, which controls the functions of internal organs and glands. Chronic stress has been associated with an imbalance in autonomic nervous system function, leading to a range of health conditions. Acupuncture is a medical treatment modality that has been applied to health care in different dimensions including physical, mental, and spiritual. This study aimed to investigate the effect of acupuncture on blood pressure, heart rate, and salivary cortisol level in mild stress university students, a population particularly vulnerable to stress. Twenty-eight university students were recruited and divided into two groups, a real acupuncture group and a sham acupuncture group. Heart rate, blood pressure, and salivary cortisol level were evaluated before and after a 30-minute acupuncture session on the ST36 acupoint. The results showed that the real acupuncture group had a significant decrease in blood pressure and heart rate, whereas the sham acupuncture group showed no change. Both groups had a slightly decrease in salivary cortisol level with no statistically significant. There was a statistically significant difference in the decrease of systolic blood pressure and heart rate after acupuncture between the two groups, but there was no significant difference between the groups in salivary cortisol level after acupuncture. The findings suggest that the acupuncture can be a valuable treatment for restoring balance to the symptoms of the autonomic nervous system in university students experiencing stress. A larger sample size, a non-intervention control, as well as different sources and times of cortisol collection, could contribute to the validation of the findings in this study.

Published: May 2024

Caffeine (CAF) removal from water resources is important because it is widely distributed and can be toxic to aquatic life. The copper supported on mesoporous carbon/silica composite (Cu/MCS) in this research was developed as a novel adsorbent to remove caffeine from aqueous solutions. The Cu/MCS material was prepared in two steps. The first step was the preparation of a precursor consisting of copper and natural rubber distributed inside a hexagonal mesoporous silica matrix (Cu/NR/HMS). Then, the composite was carbonized at high temperature under inert gas conditions to obtain Cu/MCS material. The amount of Cu loading in the MCS structure was studied. The Cu/MCS composites revealed a high level of copper distribution incorporated into the mesoporous carbon/silica framework as confirmed by Powder X-ray diffraction (XRD) and Scanning Electron Microscope and Energy Dispersive X-ray Spectrometer (SEM-EDS). The Cu/MCS materials possessed a high specific surface area (523–748 m2 g−1), large pore volume (0.80–0.86 cm3 g−1) and mesoporous diameter (3.07-3.30 nm). Fourier Transform Infrared Spectroscopy (FT-IR) and CHN analysis revealed a high amount of carbonaceous species dispersed in the Cu/MCS material. The Cu (0.010)/MCS, with copper loading of 1 mmol/g, revealed good properties for CAF removal when compared to other series of Cu/MCS adsorbents. Moreover, the Cu (0.010)/MCS composite exhibited the maximum adsorption capacity for CAF as 55.8 mg/g.

Authors: Minsan Watha , Minsan Pradthana
Published: May 2024

This study introduces hybrid forecasting models integrating the Whale Optimization Algorithm (WOA) with Holt-Winters (HW) and decomposition methods, applied in both additive and multiplicative models, for time series forecasting. Focusing on monthly water inflow into four dam reservoirs in Southern Thailand, the study compares these hybrid models against classical statistical models, Grid Search for Holt-Winters (Grid-HW) and Classical Decomposition (Classic-D). The analysis comprises two phases: the training dataset phase and the testing dataset phase. In the training phase, WOA demonstrates superior parameter optimization, enhancing both HW and decomposition methods, resulting in lower Mean Absolute Error (MAE) values compared to classical models. In the testing phase, performance metrics such as Root Mean Square Error (RMSE), MAE, and Symmetric Mean Absolute Percentage Error (sMAPE) are employed. The findings reveal that the Whale Optimization Algorithm with Holt-Winters (WOA-HW) and Decomposition (WOA-D) models surpass classical approaches in long-term forecasting accuracy for three dam reservoirs. Over 24 data points, the WOA with Multiplicative Holt-Winters (WOA-HWx) is optimal for Pran Buri dam, the WOA with Additive Decomposition (WOA-D+) for Bang Lang dam, and the WOA with Multiplicative Decomposition (WOA-Dx) for Kaeng Krachan dam. The Box-Jenkins approach, further refined through a Box-Cox transformation employing a natural logarithm, emerged as the superior forecasting model for Rajjaprabha dam. This model satisfied all critical statistical criteria, including normality of residuals (Anderson-Darling: 0.359, p-value: 0.433), homoscedasticity (Levene's test: 1.24, p-value: 0.274), independence (Ljung-Box test: 14.10, p-value: 0.169), and zero mean (t-test: -0.39, p-value: 0.702), establishing its robustness and reliability for forecast analysis.

Melasma is one of the most concerning pigmented skin conditions, especially in females. It can be influenced by sunlight, occupation, gender, and drug use, which can aggravate the disease. This split-face clinical trial assesses the effectiveness of picosecond laser in melasma treatment combined with topical azelaic acid compared with azelaic alone. The primary outcome of this study is the Hemi-MASI score, while the secondary outcome is demographic data, physicians' global assessment, patient satisfaction score, and adverse events. The study recruited twenty Thai females aged between 18 and 65 diagnosed with bilateral symmetrical malar-type melasma. The patients were treated with low fluence 1064-nm Nd:YAG picosecond laser three sessions every two weeks combined with topical azelaic acid twice daily on the right side of the face, whereas the left side was treated with topical azelaic acid twice daily alone for 16 weeks. The mean Hemi-MASI decrease is 3.52%, 9.38%, and 19.94% on the combination side, while there are 1.93%, 7.89%, and 16.73% at the 8th, 12th, and 16th, respectively in the topical azelaic alone side. There were no severe side effects from both picosecond laser and azelaic acid, and they can be relieved without treatment. Thus, the overall clinical result demonstrates the improvement as the patient satisfaction score is satisfied. Still, the mean Hemi-MASI score between the two sides is not statistically significantly different (p>0.05). In conclusion, combining the picosecond laser with azelaic acid alone in melasma treatment results in a better overall general outcome than the azelaic alone.

Published: May 2024

The purpose of this research is to analyze further the relationship and influence of price, customer experience on purchase intentions which is mediated by customer satisfaction on purchase intentions at the HaiDiLao restaurant. The method used in this research is a quantitative method and was processed using AMOS. The survey was conducted on 155 respondents who met the respondent criteria using non-probability sampling. The research found that price perception, customer experience, and customer satisfaction did not significantly influence the purchase intention. Meanwhile, price perception and customer experience had a significant influence on customer satisfaction. On the other hand, price perception and customer experience also did not significantly influence purchase intention. The limitation of the research was the limited respondents, with 155 respondents domiciled in Jakarta who have visited HaiDiLao restaurant in Jakarta. This research could be generalized more widely if the samples were taken not only from Jakarta City. The implications of this research provided managerial contributions to the food and beverages industry, especially an overview of customer experience and an understanding of the factors influencing increased purchase intentions, such as price perception, customer experience, customer satisfaction, and purchase intention. So, managers can develop a business strategic plan that aligns with internal and external company conditions.

Published: May 2024

The major royal jelly protein 2 (mrjp2) gene is one of the molecular markers that can discriminate between Apis cerana Fabricius and A. mellifera Linnaeus. Due to the lack of mrjp2 gene sequences registered in GenBank for Indonesian A. cerana and A. mellifera, DNA characterization and bioinformatics analysis were needed. This research aimed to characterize the exon-intron organization of mrjp2 genes for both Indonesian bee species and analyze the phylogenetic relationship with other mrjp family genes. DNA samples of Apis cerana and A. mellifera, collected from Bogor, were amplified using MF-MR primer at annealing temperatures of 47 oC and 50 oC, respectively. The length of A. cerana and A. mellifera DNA sequences were 579 and 597 bp, respectively. The DNA sequences of both species were comprised of partial exons 1, introns 1, exons 2, introns 2, and partial exon 3. The number of putative amino acids of A. cerana and A. mellifera mrjp2 genes were 111 and 123, respectively. We confirmed that the partial MRJP2 putative amino acids of both honey bees belong to the MRJP family and contained the peptide signal in the 14 first amino acid sites. Nucleotide variation of the mrjp2 gene in A. cerana was higher than A. mellifera. Phylogenetic tree construction showed that A. cerana and A. mellifera form a monophyletic clade with the A. mellifera mrjp7 gene and another mrjp family gene clustered as reported in a previous study.

Parkinson's disease (PD) is characterized by divergent clinical symptoms and prognosis, suggesting the presence of distinct subtypes. Identifying these subtypes is crucial for understanding the underlying pathophysiology, predicting disease progression, and developing personalized treatments. In this study, we propose a connectivity-based subtyping approach, which measures each patient's deviation from the reference structural covariance networks established in healthy controls. Using data from the Parkinson's Progression Markers Initiative, we identified two distinct subtypes of de novo PD patients: 248 patients with typical cortical-striato-thalamic dysfunctions and 41 patients showing weakened dorsal raphe nucleus (DRN)-to-cortical/striatal projections. The proposed subtyping approach demonstrated high stability in terms of random sampling of healthy or diseased population and longitudinal prediction at follow-up visits, outperforming the traditional motor phenotypes. Compared to the typical PD, patients with the DRN-predominant subtype were characterized by less server motor symptoms at baseline and distinct imaging biomarkers, including larger striatal volumes, higher concentration of cerebrospinal fluid amyloid-β and amyloid-β/t(p)-tau ratio. Subtype-specific associations and drug effects were identified that the DRN subtype exhibited more pronounced medication effects on motor symptoms, potentially regulated by DRN serotonergic modulation through striatal dopaminergic neurons. The DRN serotonergic inputs also regulated non-motor symptoms, the aggregation of CSF biomarkers and the conversion to more severe disease states. Our findings suggest that the DRN-predominant subtype represents a unique clinical and biological phenotype of PD characterized by an enhanced response to anti-parkinsonian treatment, more favorable prognosis and slower progression of dopamine depletion. This study may contribute to clinical practice of precision medicine, early invention and individualized treatments in PD and other neurodegenerative diseases.

Universities must currently comply with the legal precepts established by the UN International Convention on the Rights of Persons with Disabilities (hereinafter CRPD) ratified by Spain in 2008. Universities are no strangers to compliance with these precepts. From this perspective, the main objective of this study is to obtain as true a picture as possible of the training received and the knowledge that teachers in training in a faculty of education claim to have about this convention. Specifically, the aim is to analyze the perceptions that these professionals have of their training with respect to CRPD and inclusive education, and whether they differ according to gender, age or specializations studied. The information was collected with an instrument created ad hoc for the study using quantitative methodology. The results show that respondents are almost equally divided between those who agree and those who disagree on this issue, with a large percentage expressing a neutral opinion. Differences were also observed in the respondents' evaluations according to their age and specializations.

En la actualidad, las universidades deben guardar los preceptos legales establecidos por la Convención Internacional de la ONU sobre los derechos de las personas en situación de discapacidad (de ahora en adelante CDPD) ratificada por España en 2008. Las universidades no son agentes ajenos al cumplimiento de tales preceptos. Desde esta perspectiva, el objetivo principal de este estudio es obtener una imagen lo más real posible al respecto a la formación recibida y los conocimientos que sobre esta convención afirman poseer los profesores en formación de una facultad de educación. Concretamente, se pretenden analizar las percepciones que tienen estos profesionales sobre su formación con respecto a la CDPD y la educación inclusiva, y si difieren según el sexo, la edad o las especialidades cursadas. La información se recogió con un instrumento creado ad hoc para el estudio a través de metodología cuantitativa. Los resultados muestran que los encuestados se encuentran divididos, casi a partes iguales, entre aquellos que se manifiestan de acuerdo y aquellos que afirman lo contrario sobre estos asuntos, existiendo un amplio porcentaje que se manifiesta de manera neutra. Asimismo, se han observado diferencias en las valoraciones de los encuestados según su edad y especialidad cursada.

As plantas medicinais são produtoras de diversos metabólitos e substâncias, dentre estas pode-se citar a clorofila que confere a coloração verde a folhas das plantas. Dentre os gêneros botânicos e famílias botânicas utilizadas em experimentos científicos destacam-se a família Piperaceae e o gênero Piper. O gênero Piper e a espécie Piper marginatum Jacq. que possui em suas folhas um alto teor de clorofila o que confere a coloração verde nas mesmas e muitas das vezes este teor não é quantificado e dentre as técnicas utilizadas para se analisar o teor de concentração de clorofila destaca-se a técnica de Espectrofotometria no UV-Vis. O objetivo deste trabalho foi determinar a concentração de clorofila de diferentes extratos presente em Piper marginatum Jacq coletadas em Itacoatiara por meio da técnica de espectrofotometria no UV-Vis. As folhas de Piper marginatum Jacq. foram coletadas no Campus I da UFAM em Itacoatiara e foram levadas para o laboratório de Química onde foram limpas e submetidas ao processo de extração separadamente nos solventes (água e etanol) os extratos foram filtrados separadamente e armazenados em frasco âmbar e mantidos em temperatura adequada. Os extratos foram submetidos a diferentes tipos de testes: Teor de clorofila em UV-Vis, Refratividade, Condutividade elétrica e pH. As análises foram submetidas ao teste estatístico usando o software SISVAR para os parâmetros  testados e as absorbâncias foram analisadas pelo software SciDavis. Os resultados obtidos avaliaram que o melhor solvente para extração de clorofila foi o etanol, todavia ambos extratos se apresentaram estáveis durante os ensaios.

In the digital era, blended learning has become a focal point in the field of education. However, for the effective implementation of this approach, it is crucial to understand students' acceptance of blended learning. Therefore, this research aims to develop and validate the Blended Learning Acceptance Scale (BLAS) in the context of distance higher education. The research method involved the initial development of the acceptance scale based on a comprehensive review of collected data. The collected data were analyzed using appropriate statistical methods. The results indicate that the Blended Learning Acceptance Scale (BLAS) exhibits high validity and reliability. Furthermore, data analysis reveals that, overall, acceptance of blended learning in distance higher education is positive, with some neutral tendencies in certain aspects. This study provides valuable insights into students' acceptance of blended learning in the context of distance higher education. The developed BLAS can serve as an assessment tool to measure students' acceptance levels of blended learning. The findings of this research can serve as a robust foundation for educational institutions to formulate more effective strategies and policies in implementing blended learning.

Published: May 2024

A comparative evaluation and classification of a large group of seedless vine varieties was carried out depending on the diversity of the parameters of the female flower organs. Through the application of cluster analysis, it was found that in their vertical arrangement along the branches at the base of the fringe, they are distributed in four generalized clusters, in the middle - in six and in the top - in nine, each of them being composed of a different number of sub-clusters and varieties. There is no statistically proven influence of the location of the flower buttons in the fringe on the parameters of the female flower sphere. The presented biometric information on the female flower organs increases the possibilities for a more in-depth morphological, cytoembryological and ampelographic analysis and classification of the investigated seedless vine varieties.

The aim of this study was to estimate the quality of the Central Rhodope Sheep pedigree data in years 2005-2023. The data was provided by the Association for breeding Central Rhodope sheep, Karakachan sheep and Rhodope Cigay sheep, which is keeping the breed’s herdbook. The herdbook has 18 720 records for the studied period. Along with the individuals registered only as sires or dams, there were 22686 individuals in total in the pedigree file. The pedigree was processed by the OptiSel software package and then checked for errors with the PedigreeViewer software. All the inconsistencies found in the pedigree, cycles and the gender discrepancies, were solved by erasing the conflicting data. In total 565 sires and 12 156 dams were identified in the pedigree file. The maximum number of generations traced for an animal in the pedigree were six. Since 2014, the average pedigree completeness index is over 98% for the first generation, and for second and third increases from 58% to 100%, and from 38% to 94%, respectively. In the recent five years, the average number of equivalent generations by year of birth is between 2.145 to 3.159, and the average number of full generations 1.839 to 2.537. These results indicate that the cumulated pedigree data might be used for analyses of the population structure and genetic diversity of the Central Rhodope Sheep breed.

Fumonisins are produced by fungi of the genus Fusarium spp., which are widely spread out in the nature. They are produced during grain growth, ripening and harvesting and are known as “field mycotoxins“. Fusarium species can produce compounds that are toxic to animals and humans. In this study, the development of Fusarium toxins was determined in healthy and mechanically damaged barley grains treated and untreated with fungicide, respectively, under natural contamination. It was found that healthy kernels treated with fungicide had the highest yield of 6700 kg.ha-1 followed by the yield of damaged kernels treated with fungicide. The lowest yield of 4850 kg.ha-1 was reported for the damaged and untreated barley grains. The two treatments whose plants were treated with fungicide had a higher yield than their counterparts, i.e. the plants not treated with fungicide. In confirmation of this by mycotoxicological analysis was established the presence of fumonisin 0.234 mg.kg-1 in healthy seeds untreated with fungicide and 0.274 mg.kg-1 in mechanically damaged untreated seeds. Fumonisin concentrations were measured by using Enzyme-Linked Immunosorbent Assay (ELISA) method. The used approach in this study shows that fungicide treatments effectively reduce mycotoxin levels in barley and increase grain yield. The use of fungicides should be combined with other infection mitigation strategies, such as avoiding mechanically damaged grains, which are a suitable substrate for mycotoxins production. These measures will help to improve food and feed safety.

Published: May 2024

This paper aims to develop a MAGDM model using single-valued neutrosophic credibility matrix (SVNCM) energy in a SVNCM scenario. To do it, first, SVNCM energy and its score function are presented as a conceptual extension of existing single-valued neutrosophic matrix (SVNM) energy. Then, a MAGDM model is developed in terms of SVNCM energy and its score function in a SVNCM scenario and also its decision algorithm is provided to solve MAGDM problems with SVNCMs. Finally, the developed MAGDM model is applied in the school site selection problem as an actual example, then the comparative investigation of the decision results in the SVNM and SVNCM scenarios indicates the superiority of the developed model over existing MAGDM model.
