Artificial Neural Network; Deep Neural Network; Nifty 50; Principal Component Analysis (PCA); Stock market
Soft computing techniques have been increasingly used for stock market analysis in the past few years because they can capture nonlinear aspects which traditional econometric models do not adequately capture. With different techniques like Artificial Neural Networks, Deep Neural Networks and Stacked Autoencoders available, in this paper, the author tries to determine which of the above methods can model the Indian stock market with higher accuracy. In this study, high-frequency data from Nifty 50 is used, and various feature selection techniques such as PCA and linear regression are used for each of the above machine learning models to predict the Nifty 50 data. Finally, all predictions from the different techniques are compared with the actual index movement and the best method for Nifty 50 is suggested. 2025 Seventh Sense Research Group

A Deep Learning-Based BCI System for Emotion Classification Using EEG Signals
Attention-Based Bidirectional Gated Recurrent Unit; Convolutional Autoencoder; DEAP; Graph Convolutional Network; SEED
Electroencephalography-based Brain-Computer Interfacing (EEG-BCI) technologies allow for effortless interaction between external hardware and the human brain through monitoring its electric signals. These systems rely on EEG recordings, which provide non-invasive and real-time neural information through electrodes placed on the scalp. To advance emotion-recognizing efficiency and accuracy, this study proposes a deep learning-based method that can extract valuable temporal and spatial information from EEG signals. The proposed model includes the use of a Graph Convolution Network (GCN) for learning spatial relationships between different EEG channels to model the data in graph form and gain features through that modelling. A Convolutional Autoencoder (CAE) is then used to compress data to low dimensions and to reconstruct it so that major features are not ignored. Furthermore, the model uses an Attention-based Bidirectional Gated Recurrent Unit (ABiGRU) for temporal classification, which can emphasize the most important time steps in both backwards and forward directions. Two standard datasets are employed to test the developed approach. The DEAP dataset is used for emotion recognition with a binary response, and SEED is used with multi-class classification. The model attains great results of 98.12% accuracy on DEAP and 97.58% on SEED datasets. The very high performances show the efficacy of the model for decoding emotional states from EEG signals and very strong potential for real-time emotion recognition in affective computing and BCI. 2026 Seventh Sense Research Group.

Canonical Correlation; Deep Belief Networks and Convolutional Neural Networks; Hate Speech Detection; Krill Herd Algorithm
Social networking uses internet-based platforms to facilitate users to make connections with others and share various forms of content, including text, images, videos, and links. Social networking services are mainly used for non-social interpersonal communication. Many approaches have been developed for hate speech detection, but they still face significant challenges, particularly in classifying text into multiple labels accurately and in a timely manner. For accurate hate speech detection in social networks, a Censored Regressive Canonical Optimized Convolutional Deep Belief Classifier (CRCOCDBC) model is developed. The objective of the developed CRCOCDBC is to detect multi-class hate speech with minimal time and error rate. Comparative analysis shows improved performance in terms of minimum error and higher authentication accuracy and precision than other well-known methods. 2026 Seventh Sense Research Group.

Precision Food Crop Mapping Using Deep Neural Networks and Improved Dipper Throat Optimization Techniques
Feature Extractor; Food Crop Classification; Levy Flight; Remote Sensing; Sobel Filter
In recent times, the use of Remote Sensing (RS) data obtained from Unmanned Aerial Vehicles (UAVs) has gained significant popularity in crop classification tasks, including crop mapping, yield prediction, and soil classification. The classification of food crops utilizing RS Imageries (RSI) is a major application of RS tools in crop growing. Meeting the conditions for investigating these data requires more difficult approaches, and Artificial Intelligence (AI) technologies offer the mandatory support. Because of the variation and division of crop planting, archetypal classification methods have fewer classification outcomes. This manuscript focuses on the design and execution of a Leveraging Enhanced Dipper Throat Optimization Algorithm with Dipper-Inspired Precision Classification for Remote-sensed Optimized (DIP-CROP) Processing methodology. The drive of the DIP-CROP algorithm is to classify distinct types of crops that exist in remote sensing. At first, the DIP-CROP model applies image processing using the Sobel Filter (SF) to eliminate the noise. Next, the presented DIP-CROP technique takes place SqueezeNet model is employed for the feature extractor. To classify the food crop types, the DIP-CROP approach utilizes a Multi-Head Attention-based Bi-directional Long Short Term Memory (MHA-BiLSTM) algorithm. For hyperparameter tuning of the MHA-BiLSTM classifier, the Enhanced Dipper Throat Optimization Algorithm (EDTOA) will be applied in this work. The optimization process utilizes Levy flight distribution, which is known for its faster convergence due to efficient exploration of the search space. Levy flights can be used to take larger steps in exploration, which prevents getting stuck in local minima and accelerates convergence. The performance of the DIP CROP method is examined experimentally using a benchmark database. Experimental results affirmed the superior solution of the DIP-CROP algorithm over existing methods. 2026 Seventh Sense Research Group.

UWB Monostatic RADAR-Based Heartbeat Monitoring in an Autonomous Vehicle
Non-Invasive Heartbeat Detection; Scattering Parameter; UWB Monostatic Radar; UWB Propagation; Vehicular Communication
Monitoring a driver's physiological state in real time is vital for enhancing road safety by detecting fatigue, medical emergencies, and enabling future health-intervention systems in autonomous vehicles. Ultra-Wideband (UWB) impulse radio monostatic Radar emerges as an attractive alternative due to its ability to perform non-invasive and highly sensitive detection of vital signs, including respiration and heart rate, through obstacles such as clothing or car seats. This paper presents a radar setup located in the seat, which propagates a UWB signal through human tissues from the back side of the driver up to the heart location. The transmitted and reflected UWB signal and antenna reflection coefficient S11 parameter are analysed to detect the heart rate for a heartbeat-induced heart model. Various UWB pulse types and their spectral characteristics are analysed to ensure efficient energy transmission within the FCC mask safety constraints. Time-domain analysis of the transmitted and received pulses reveals clear heartbeat analysis with minimal distortion, achieving accurate heart detection rates. Reflected-pulse analysis shows clear differences in amplitude between systole and diastole for normal and abnormal heart-radius conditions, allowing reliable detection of heart states. Time-of-flight and range estimation help in tracking the heart-wall movement accurately. FFT-based analysis of the time-varying S11 parameter estimates the heart rate, confirming precise non-invasive heartbeat detection through the thorax. .

Enhancing Image Classification Performance through Hybrid Self-Supervised Learning Strategies
Computer Vision; Contrastive Clustering; Hybrid SSL; Image classification; Multi-Modal; Self-Supervised
Image classification is a cornerstone of computer vision, with the applications spanning healthcare, autonomous driving and security. The dependence on large labeled datasets for supervised learning poses significant challenges, particularly in specialized fields where the labeled data is scarce and expensive to obtain. Self-supervised learning (SSL) has emerged as a promising paradigm, enabling models to learn useful representations from unlabelled data by designing pretext tasks that generate pseudo-labels. SSL faces limitations in handling complex data distributions and achieving robust generalization. This paper explores hybrid self-supervised learning strategies that combine multiple SSL techniques, such as contrastive learning, masked image modeling, and clustering, to enhance image classification performance and reduce dependence on labeled data. This study proposes a comprehensive framework that integrates data augmentation, feature extraction, and hybrid learning mechanisms, evaluated on the CIFAR-100 dataset. The experimental results demonstrate that hybrid SSL approaches achieve significant improvements in performance. The combination of SimCLR and masked image modeling (MAE) achieves a Top-1 accuracy of 77.8% on the clean test set and 71.4% on the domain-shifted set, and self-distillation with contrastive learning (DINO) achieves the highest Top-1 accuracy of 78.4% on the clean test set and 72.1% on the domain-shifted set. Advanced data augmentation techniques, such as CutMix and RandAugment, additionally enhance model robustness, with SwAV (contrastive clustering) achieving 76.5% Top-1 accuracy on the clean test set and 70.1% on the domain-shifted set. The findings highlight the effectiveness of hybrid SSL methods in addressing the challenges of limited labelled data, offering valuable insights for future research and applications in image classification. 2025 Seventh Sense Research Group.

From Fabric to Function: Decoding Athleisure Wear Adoption through Fit-inspired Lifestyle and Social Influence; [Od tkanine do funkcionalnosti: analiza sprejemanja portno-elegantnih obla?il skozi zdrav ivljenjski slog in drubeni vpliv]
brand reputation; enclothed cognition; lifestyle; product attributes; sustainability
Athleisure wear has emerged as a prominent trend in the fashion industry, particularly among educated youth in India, and is driven by a growing focus on fitness, health and comfort. This study, based on the stimulus-organism-response model, examines the factors influencing athleisure wear purchase intention, with a focus on fit-inspired lifestyle, perceived product quality, social influence and brand reputation. The study examines how these factors influence enclothed cognition, ultimately impacting purchase intention. Partial least squares-structural equation modelling, based on the two-step approach, was employed using SmartPLS 4.0 software for data analysis. Data collected from young consumers in Bangalore indicated that a fit-inspired lifestyle, perceived product attributes and social influence had a positive influence on enclothed cognition, while brand reputation did not show a significant relationship. Additionally, enclothed cognition was found to be a significant predictor of purchase intention. The results suggest that the alignment of athleisure wear with a fit-inspired lifestyle, functional attributes and social validation plays a crucial role in shaping purchase intention. The study offers practical insights for marketers to focus on lifestyle alignment, product functionality and social engagement in their marketing strategies. The findings also highlight a shift in consumer behaviour where experiential and value-driven factors, such as product benefits and lifestyle fit, outweigh traditional brand reputation. Future research should include exploring diverse demographic segments, longterm behavioural patterns and the impact of sustainability and cultural values on purchase behaviour in the area of athleisure wear. 2026, University of Ljubljana Press.

Digital Adoption and Price Discovery in Shadows: Evidence from Indian IPO Grey Markets between 2016-2025
firm-specific factors; grey market premium; IPO market; listing day premium; under-pricing
This study examines the role of digital adoption and price discovery through informal IPO markets in India. Due to price anomalies, sentiments around the IPO listing day are channelised through Informal markets known as grey markets. This study verifies the determinants of grey market IPO prices and their linkages with the formal market IPO under-pricing. Apart from dominant market and firm-specific factors, it examines how digital adoption variables such as digital payment usage and new demat accounts affect the IPO prices in both channels. In the post-pandemic period, there is a surge in the number of IPOs offered and participation of institutions and individuals in IPOs. Grey market allows traders to bid on IPO applications before they are officially listed, helping to assess under-pricing in issue prices, if any. This study uses data of 1,155 IPOs that went public in India between 2016 and 2025. Using OLS models, the study examines the relationships among variables, and findings indicate that both grey market activity and digital adoption directly influence listing day pri ces, confirming that under-pricing is predictable through informal channels. Investors should consider these factors, in addition to fundamental aspects, when making IPO investment decisions. 2025, ASERS Publishing House. All rights reserved.

adaptive content personalization; artificial intelligence-based English as a secondary language learning; Cognitive load management
Traditional English as a Secondary Language (ESL) learning platform rely on static content delivery, often failing to adapt to individual learners cognitive capacities, leading to inefficient comprehension and increased cognitive load. A novel hybrid Feedforward Neural Network and Bidirectional Encoder Representation Transformer (FNN-BERT) framework stands as our solution because it performs dynamic content personalization through predictions of real-time cognitive load. The proposed approach incorporates Feedforward Neural Networks (FNN) alongside Bidirectional Encoder Representations from Transformers (BERT) to process behavioral analytics for optimized content complexity adjustment and adaptive and scalable learning delivery. Real-time adaptability, scalability and high computational needs of current models reduce their effectiveness in personalized learning environments. Through the application of Test of English for International Communication (TOEIC), International English Language Testing System (IELTS) and Test of English as a Foreign Language (TOEFL) datasets, our methodology uses Feedforward Neural Network (FNN) to forecast cognitive load based on student engagement behaviors and application errors then Bidirectional Encoders Representations from Transformer (BERT) processes content difficulty adjustments automatically. The proposed model delivers a 95.3% accuracy rate, 96.22% precision level, 96.1% recall capability and 97.2% F1-score which surpasses conventional Artificial Intelligence-based English as a Secondary Language (ESL) learning systems. The system makes use of Python for its implementation to improve understanding as well as student focus and mental processing speed. Personalized content presentation methods lead to lower cognitive strain which simultaneously advances student achievement numbers. The research adds value to smart educational frameworks through its introduction of a scalable framework that allows adaptable learning systems for English as a second language (ESL). The following research steps include simplifying system complexity while adding multimodal learning signals including eye monitoring and speech recognition and further developing the model across various educational subject areas. The research works as a promising foundation which propels AI real-time adaptive education systems for students from various backgrounds. (2025), (Science and Information Organization).

Attention and Representation Learning in Byte-Level Digital Forensics: A Survey of Methods, Challenges, and Applications
attention mechanisms; Byte-level digital forensics; deep learning; file fragment classification; forensic robustness; representation learning
Byte-level analysis has become an essential capability in digital forensics, enabling content-based investigation when file system metadata, headers, or structural information are unavailable or unreliable. Recent advances in deep learning allow forensic systems to learn discriminative features directly from raw byte streams; however, the growing diversity of representation strategies, architectural designs, and attention mechanisms makes it difficult to assess their relative effectiveness and practical suitability. This study presents a structured survey of representation learning and attention-based approaches for byte-level digital forensic analysis. We examine statistical, embedding-based, image-based, sequential, and hybrid representations, and analyze how architectural choices and attention mechanisms influence performance, robustness, and scalability. Across the literature, hybrid representations combined with lightweight convolutional backbones and selective attention mechanisms consistently provide a favorable balance between accuracy and computational efficiency. The survey also reviews key forensic applications, including file fragment classification, malware and binary analysis, network payload forensics, and encrypted or compressed data triage. In addition, we critically discuss challenges related to distribution shift, dataset bias, adversarial vulnerability, interpretability, and reproducibility, along with practical considerations for deployment in large-scale forensic pipelines. By synthesizing architectural trends, operational constraints, and reliability concerns, this work identifies critical research gaps and provides a structured foundation for the development of robust and trustworthy byte-level forensic learning systems.

barbados cherry; biofertilizer; gootee; root growth; shoot growth; survivability
This study evaluated the efficacy of air layering in combination with biofertilizer treatments for the successful propagation of West Indian cherry (Malpighia glabra L.) during 20222023 at the North Farm, School of Agricultural Sciences, Karunya Institute of Technology and Sciences, Coimbatore, Tamil Nadu, India. Air layering was performed on a 9-year-old tree using 1-year-old, pencil-thick shoots of 60 cm length. Once rooted, the air layers were gradually detached from the mother plant and transplanted into polybags. Biofertilizer treatments were applied to the potting medium and as soil drenches, including Trichoderma viride (3 g L-1), vermiwash (1 %), humic acid (20 g L-1), Azospirillum brasilense (2 g kg-1 planting medium), plant growth-promoting rhizobacteria (PGPR; 10 g plant-1) and vesicular-arbuscular mycorrhiza (VAM; 100 g plant-1), along with an untreated control. Data recorded at 60 days after detachment (DAD) showed that vermiwash @ 1 % (T3) significantly enhanced shoot and root growth parameters. It resulted in the highest plant height (45.23 cm), number of leaves (38.22), number of shoots (6.45), survival percentage (81.04 %), root length (13.80 cm), primary roots (26.31), secondary roots (78.23) and root diameter (4.88 mm). The improved performance under vermiwash treatment is attributed to its rich content of plant growth regulators, enzymes, micronutrients and beneficial microbes, which positively influenced both vegetative and root development. The results underscore the potential of integrating air layering with nutrient-enriched organic treatments like vermiwash to enhance the propagation efficiency and field establishment of West Indian cherry. The objective of this study was to identify an effective biofertilizer-based strategy to enhance survival, growth and nursery establishment of air-layered West Indian cherry saplings.

Mosquito larvicidal property of Citrus species
Citrus species; LC50; mosquito larvicide; rutaceae
Mosquitoes and their larvae have several detrimental effects on humans, animals and the environment.. Their bites cause itching, allergic reactions and skin irritation. Mosquito larvae thrive in stagnant water, polluting water sources and creating breeding grounds for further infestations. Large mosquito populations negatively impact agriculture and livestock by transmitting diseases to animals. Additionally, their presence reduces outdoor activities, affecting tourism and economic productivity in affected regions. The review focuses on the Culicidae mosquito genera Anopheles, Aedes and Culex, including many species in each. The papers show that Clevenger and Soxhlet apparatus methods maintain high-quality and quantity oils because of their unique properties. These methods are cost-effective and environmentally friendly since chloroform, carbon tetrafluoride and other similar pollutants are not used, which causes severe health issues.Future research will examine how oil release from plant parts varies with age and how this relates to mosquito mortality. Different plant parts may yield varying quantities of oil at different stages, which can be considered as a point of discussion. The present findings supportthe efficiency of certain Citrus species in the Rutaceae family to eradicate mosquitoes and its larvae. The Author(s).

Effect of heavy metal elicitation on antioxidants and andrographolide content in cell suspension cultures of Andrographis paniculata
Andrographis paniculata; andrographolide; arsenic; cadmium; flavonoids; mercury; phenols
Andrographolide, a bicyclic diterpene from Andrographis paniculata is of immense pharmaceutical importance. A. paniculata, an annual herb from Acanthaceae is widespread in the Indian subcontinent. Heavy metals act as abiotic elicitors. The study deals with the effect of mercury (Hg), cadmium (Cd) and arsenic (As) on andrographolide content, phenols and flavonoids and each of their correlation with the metal chelating and radical scavenging activity, in cell suspension cultures of A. paniculata. Andrographolide was estimated using HPLC, while other estimation methods were used for other metabolites. Four different concentrations of each of the heavy metal salts CdCl2, As2O3and HgCl2, were administered in liquid MS media containing 1 g of cells. Media without any metal served as control. Higher concentrations of Cd and As imparted a positive effect on andrographolide content, Hg imparted a negative effect. The cells were most sensitive to Hg and most tolerant to Cd. Cd could be the best choice as an elicitor for increased production of andrographolide. While phenols show a positive correlation with antioxidants, flavonoids and andrographolides do not show a positive correlation with antioxidants. The Author(s).

Endophytic fungi are potential sources of bioactive compounds with therapeutic properties. This study investigated the fungal endophytes associated with Nilgirianthus ciliatus, an endangered medicinal plant, to discover its secondary metabolites and bioactivities. Molecular analysis revealed the prominent species to be Aspergillus niger, Didymella sp., Trichoderma viride, Bipolaris zeicola and Nigrospora sphaerica. Alkaloids, flavonoids, phenolics, terpenes and saponins were detected in ethyl acetate extracts employing phytochemical screening. Didymella sp. has showed the highest level of antioxidant activity, demonstrating strong DPPH radical scavenging and reduction capability. T. viride had strong antibacterial action against Klebsiella pneumoniae and Escherichia coli, meanwhile Didymella sp. and N. sphaerica were most effective against E. coli. GC-MS analysis uncovered many bioactive chemicals, including trans-farnesol and pentadecanoic acid, which are renowned for their antibacterial and antioxidant properties. These findings highlight the presence of the rich variety of diverse endophytic fungi harboring such medicinal plants, which offer promising applications in medicine, biotechnology and agriculture as sources of novel bioactive compounds. Further exploration and characterization of these strains could unlock valuable sustainable resources for various industries. The Author(s).

Phytochemical profiling and evaluation of antioxidant and anti-inflammatory activities of Ipomoea alba L.
anti-inflammatory activity; antioxidants; HPLC analysis; Ipomoea alba; phytochemicals
Plant-based medicine has been one of the oldest therapeutic practices in India and continues to offer valuable treatments for various ailments. Ipomoea alba, commonly known as morning glory, belongs to the family Convolvulaceae and is native to the tropical and subtropical regions of North and South America. It is renowned for its large, fragrant, nocturnal blooms, this plant holds significant potential in traditional medicine, particularly for managing gastrointestinal disorders, inflammation, and skin conditions. The nutrient content of Ipomoea alba leaves and seeds has demonstrated promising health benefits. This study investigated the phytochemical profile of Ipomoea alba leaves using three solvents: water, methanol, and chloroform. Phytochemical analysis confirmed the presence of carbohydrates, proteins, alkaloids, flavonoids, saponins, and tannins. HPLC analysis identified the presence of phenols in the aqueous extract, albeit in small quantities. Among the three extracts,the methanolic extract exhibited the highest antioxidant activity, as determined by DPPH, ABTS, and FRAP assays. Anti-inflammatory activity, assessed using a proteinase inhibitory assay, demonstrated that the methanolic extract showed the greatest inhibition at lower concentrations compared to the aqueous and chloroform extracts. The results suggest that the antioxidant and anti-inflammatory properties of Ipomoea alba may hold potential applications in cancer prevention and treatment. Future studies will aim to evaluate its cytotoxic effects, thereby exploring its potential role in cancer therapy. The Author(s).

Antibiofilm and anti-quorum properties of ethanolic leaf extracts of Syzygium jambos and Psidium guajava and their gel formulation for wound healing applications
AgNPs; anti-quorum; antibiofilm; Psidium guajava; Syzygium jambos; wound healing
Most bacterial species today have evolved with time and gained resistance to a wide range of antibiotics, primarily due to formation of biofilms and ?-lactamases. Many phytochemicals have been explored for their ability to inhibit bacterial biofilms. The present study sheds light on antibiofilm properties of two such plants viz. Psidium guajava and Syzygium jambos, of the Myrtaceae family. They were found to be effective against four different biofilm forming pathogens - Chromobacterium violaceum, Klebsiella pneumoniae, Pseudomonas aeruginosa and Staphylococcus aureus. Synergistic use of the plant extracts showed slightly better antibacterial activity than a single extract. Quorum sensing being one of the key factors required for biofilm formation, the isolate Chromobacterium violaceum was used as the indicator organism to study the anti-quorum properties of the plant extracts. At 10 mg/mL, ethanolic extract of S. jambos inhibited violacein pigment the most (78.84%) and therefore can be considered as a quorum sensing inhibitor (QSI). Since silver nanoparticles (AgNPs) have become increasingly significant in the field of drug delivery, they may be utilized to coat implants to avoid subsequent infections in patients who have had implant surgery and to reduce biofilm development in pathogens. In the present study, five gels were formulated using plant extracts and AgNPs, of which two showed promising results in wound healing assay. The non-toxic nature of the synthesized gels has been verified by studies on L-929 mouse fibroblast cell lines, which opens the door for their prospective application as topical treatments to accelerate the healing process in both acute and chronic wounds. Given that S. aureus and P. aeruginosa are the most commonly isolated bacteria from diabetic foot ulcers, the resulting gels can considerably curb the spread of infection and gangrene and thus prevent amputation.

Sustainable mosquito control: A tool in the fight against Aedes aegypti using Flemingia wightiana
larvicide; nanoparticles; oxidative stress; Zika virus
Mosquito-borne diseases, particularly those transmitted by Aedes aegypti, have been proven to be a global health challenge. A. aegypti, a major vector of Zika virus, Dengue virus, Chikungunya, is traditionally controlled through synthetic insecticides. However, the factor of environmental issues and rising insecticide resistant breeds have prompted the exploration of eco-friendly and sustainable alternatives. Here, we attempt to use the leaf extract of Flemingia wightiana to produce silver nanoparticles (FWAgNP). The construct of AgNPs was first indicated by UV-Vis spectroscopy, with a peak at 461 nm. NP was then characterized by SEM, EDX and functional groups were analyzed using FTIR spectroscopy. Safety assessments of synthesized NP were carried out on Oreochromis niloticus. Percentage mortality was studied on A. Aegypti with both test samples, FWAgNP and FWME. FWAgNP were found to be effective; the lowest percentage mortality of 70 % was recorded for forth instar larvae and 100 % mortality was observed in the first and second instar larvae. Oxidative stress assays such as AChe, SOD, CAT, GSH and GST were carried out. SOD, CAT and GSH showed significant elevated levels. GST and AChe levels reduced as the concentration increased, indicating the role of test samples in oxidative stress. Antiviral assay was conducted to check the effect of AgNPs in inhibiting the growth and infection of Zika virus (ZIKV) on Vero cells. The percentage inhibition property of AgNP was found to be 25 %. In conclusion, the developed FWAgNPs have significant potential in the control of vectors and a limited inhibitory activity on Zika virus. The Author(s).
