Automated detection of Breast Cancer after Neoadjuvant Chemotherapy (NAC) complete response using deep neural networks with X-ray images

Paper ID- AMA-12-12-2023-12774

This study explores the application of Convolutional Neural Network (CNN) models in predicting neoadjuvant chemotherapy (NAC) responses through Magnetic Resonance Imaging (MRI) data in breast cancer patients. It aims to enhance prognosis monitoring by leveraging AI-driven image analysis, providing a computational interface for detailed radiological data analysis. Utilizing a dataset encompassing patients' radiological responses post-NAC, a CNN-based model has been developed using the YOLO algorithm. The model's predictive success with new data aimed to refine and improve its performance. The study demonstrates the potential of AI-driven deep learning models, particularly CNNs, in effectively predicting treatment responses through radiological data analysis. This approach combines detailed analysis of radiological data with a computational interface, aiming to aid physicians in their research efforts. The developed CNN model, utilizing the YOLO algorithm, achieved notable performance metrics in predicting neoadjuvant chemotherapy (NAC) responses in breast cancer patients. The developed CNN model, leveraging the YOLO algorithm, achieved significant performance metrics in predicting neoadjuvant chemotherapy (NAC) responses in breast cancer patients with an average precision of 71%, an average accuracy of 70.51%, and an Intersection over Union (IoU) value of 67.00%. The developed interface, implemented using the Python Tkinter library, provided rapid prediction results for new MRI images, completing predictions in under one second. This interface integrated the trained model's weight file, facilitating prediction in various hospital systems with minimal hardware capacities. This research underlines the significance of machine learning and deep learning in interpreting heterogeneous medical data, particularly in medical imaging analysis. The utilization of AI-based models doesn't aim to replace clinicians but serves as a collaborative tool to reduce workload and enhance diagnostic accuracy. While medical imaging methods have significantly advanced, this study emphasizes the potential of AI-driven models in exploiting invisible image features to improve predictive capabilities.

Selection Indices in Vegetable Cowpea (Vigna unguiculata)

Paper ID- AMA-12-12-2023-12771

To create selection indices, fifty various vegetable cowpea genotypes were assessed for twelve traits. Characters were taken into consideration as selection index criteria if they had a desirable correlation as well as moderate to high direct effect on green pod yield per plant. For the purpose of generating selection indices, the green pod yield per plant (X1) and its four components including pod length (X2), number of pods per cluster (X3), number of pods per plant (X4) and ten pod weight (X5) were identified. The selection index based on single character was efficient over straight selection for green pod yield per plant and showed maximum gain and relative efficiency. The efficiency of selection increased with the inclusion of more number of characters in the index. The index based on five characters viz., green pod yield per plant, pod length, number of pods per cluster, number of pods per plant and ten pod weight recorded highest genetic advance and relative efficiency followed by green pod yield per plant, pod length, number of pods per plant and ten pod weight.

Genetic variability and diversity in vegetable cowpea (Vigna unguiculata)

Paper ID- AMA-11-12-2023-12770

The experiment was conducted to evaluate 50 genotypes of vegetable cowpea to know the magnitude of genetic variability, heritability, genetic advance and genetic divergence. Phenotypic observations were meticulously recorded for days to 50 per cent flowering, days to first green pod picking, number of primary branches per plant, plant height (cm), pod length (cm), pod width (cm), number of pods per plant, number of seeds per pod, number of pods per cluster, number of clusters per plant, ten pod weight (g) and green pod yield per plant (g). The magnitude of PCV was slightly greater than GCV which revealed that very little influence of environmental variation was observed on all the characters and stated that a sufficient amount of variability was noticed. The high genotypic coefficient of variation and phenotypic coefficient of variation was observed for plant height, green pod yield per plant, ten pod weight and number of pods per plant. For pod length, number of seeds per pod, plant height, ten pod weight, green pod yield per plant, number of primary branches per plant, number of pods per plant, number of clusters per plant, and number of pods per cluster, estimates of high heritability along with high genetic advance expressed as a percent of mean were noted. Utilizing a cluster analysis, the fifty genotypes were categorized into six distinct clusters. The maximum inter-cluster distance was found between clusters IV and VI. In this context, genotypes from cluster IV and VI should be selected as parents in hybridization programme as they showed highest genetic diversity.

Genetic Architecture of seed cotton yield and its component traits in cotton (Gossypium hirsutum L.)

Paper ID- AMA-11-12-2023-12769

The present investigation was undertaken with a view to generate genetic information on gene effects for seed cotton yield per plant in cotton (Gossypium hirsutum L.) using 21 generations. Special scaling tests such as (B1-L1), (B2-L2) and (F2-L3) were significant either in cross 1 or cross 2 for all the four traits besides significance of other tests showing presence of epistasis. The 𝜒2(2) value at 15 degrees of freedom were significant in all the traits in both crosses supported the presence of higher order epistasis and /or linked digenic interaction. The 𝜒2(3) value at 11 degrees of freedom was significant for all the four traits in both the crosses indicating the presence of higher order epistasis. The 𝜒2(4) value at 9 degrees of freedom was significant for all the four traits in both the crosses indicating the presence of higher order linkage.

Genetic Analysis of Homogenous and Heterogeneous Populations in Mungbean [Vigna Radiata (L.) Wilczek]

Paper ID- AMA-11-12-2023-12768

Combining ability analysis for yield and yield components of mungbean (Vigna radiata L. Wilczek) was conducted using an 8 x 8 diallel mating system both in F1 and F2 generations. Both gca and sca mean squares were significant for all the eleven characters in F1 and F2 generations, former being more pronounced for clusters per plant, pods per cluster, pods per plant, pod length, seeds per pod, 100-seed weight and seed yield per plant in F1 and for all the characters except days to maturity, seeds per pod and 100-seed weight in F2. The parent K 851 was a good general combiner for seed yield per plant, days to maturity, plant height, primary branches per plant, clusters per plant, pods per plant and seeds per pod in both generations. While Pant-M 4 was good general combiner for seed yield per plant, plant height, pods per cluster and pods per plant over generations. Parents RMG 62 and Asha were the best combiners for early flowering. GM 4 had good general combining ability for seed yield in F1, but for pod length and 100-seed weight in F1 and F2. The crosses showing high sca effects for seed yield also had significant and positive effects for at least two important yield components.
