Detecting Cyberbullying in Twitter: A Multi-Model Approach
With cyberbullying surging across social media, this study investigates the effectiveness of four prominent deep learning models - CNN, Bi-LSTM, GRU, and LSTM - in identifying cyberbullying within Twitter texts. Driven by the urgent need for robust tools, this research aims to enrich the field of cyberbullying detection by thoroughly evaluating these models' capabilities. A dataset of Twitter texts served as the training ground, rigorously preprocessed to ensure optimal model compatibility. Each model, CNN, Bi-LSTM, GRU, and LSTM, underwent independent training and evaluation, revealing distinct performance levels: CNN achieved the highest accuracy at 83.10%, followed by Bi-LSTM (81.90%), GRU (81.73%), and LSTM (16.07%). These differences highlight the unique strengths of each architecture in analysing and representing text data. The findings highlight the CNN model's superior performance, indicating its potential as a highly effective tool for Twitter-based cyberbullying detection. While the deep learning models explored here offer promising avenues for detecting cyberbullying on Twitter, their performance highlights the complexities inherent in this task. The limited space of tweets can often obscure the true intent behind words, making accurate identification a nuanced challenge. Despite this, the CNN model's robust performance suggests that carefully chosen architectures hold significant potential for combating online harassment. This research paves the way for further explorations in harnessing the power of AI to create a safer and more civil online experience where respectful communication can flourish even within the constraints of concision. 2024 IEEE. -

Detecting Abusive Comments in Mizo: A Machine Learning Approach for a Low-Resource Language
The detection of abusive language in online spaces is crucial for ensuring a safe digital environment, particularly for low-resource languages like Mizo. Mizo, a tonal Tibeto-Burman language spoken primarily in Mizoram, India, poses significant computational challenges due to its phonetic complexity and limited linguistic resources. This research presents a method based on machine learning for abusive comment detection in Mizo, addressing the lack of annotated datasets and specialized NLP tools. A structured pipeline involving data collection, preprocessing, feature engineering, and model evaluation was implemented. Our study compares the effectiveness of several conventional machine learning methods, such as Random Forest, Support Vector Machines (SVM), Logistic Regression, and XGBoost, against transformer-based models such as Multilingual BERT(mBERT) and MizBERT. According to experimental data, MizBERT achieves the highest accuracy and F1-score, outperforming all other models by a substantial margin. This work contributes to the development of computational tools for Mizo NLP, laying a foundation for automated moderation systems and fostering digital inclusivity for Mizo-Speaking communities. 2025 IEEE. -

The compounds containing chiral centers and different functional groups serve as magnificent building blocks for the preparation of various natural products that are having immense biological activity. Dimethyl-8-oxa-bicyclo[3.2.1]oct-6-en-3-ol is one of the wonderful synthons to construct multiple stereo centers at a time during the asymmetric synthesis. In this account, we discuss our research efforts toward the synthesis of various simple and complex natural products from the past three decades (19952020) by using dimethyl-8-oxa-bicyclo[3.2.1]oct-6-en-3-ol as a synthon. Moreover, the synthetic utility of this starting material was investigated and well demonstrated. Further, we executed the desymmetrization of dimethyl-8-oxa-bicyclo[3.2.1]oct-6-en-3-ol by hydroboration to get different chiral centers. After obtaining the stereocenters, we could manage either the fragment, formal or total synthesis of natural products, by simple protection and deprotection sequence followed by C?C bond formation steps. 2021 The Chemical Society of Japan & Wiley-VCH GmbH -

Over the past many decades, the travel and tourism industry has been at the forefront of adapting to new changes and accepting the latest technologies. Today's travelers are sophisticated and knowledgeable, as they have all the information available to them easily, which contributes to fast and quick decision making. The world is gradually changing into a much more intelligent and advanced platform that makes it possible to employ techniques like augmented reality, virtual reality, and artificial intelligence. This has proven to be very successful in a variety of fields, including education, healthcare, marketing, and communication. The current study focuses on incorporating smart tourism strategies to build a sustainable ecosystem at destinations, which enhances the competitiveness of the destination and makes it easier for value co- creation among the different stakeholders. Research suggests that although industry-led and government-initiated projects seem to prioritize the use of smart applications in destinations in theory, practical implementation appears to lag behind. Less research has been done in India on gamification, smart wearable technology at travel destinations, and the practical application of AR and VR tools. The study revolves around the South Indian State of Kerala, which has been a pioneer in tourism promotion in the country. In addition to proposing a framework for destination management and tourism competitiveness with smart tourism applications, this study aims to investigate the practical implications of smart tourism tools and technologies at destinations. To shed more light on the findings, a mixed methodology approach is used to analyze the data using a mix of quantitative and qualitative methods. The study's conclusions have significant ramifications for destination management, strategic planning, and the application of smart technologies at travel locations. -
Destination image and perceived meaningfulness for visitor loyalty: A strategic positioning of Indian destinations
The purpose of this study is to empirically test and validate a multi-dimensional structure of In-loco Destination Image and perceived meaningfulness using an integrated model of visitor loyalty. The model was tested using data collected from responses of foreign tourists visiting India (n = 246). The results identified six dimensions of In-loco Destination Image: Amenities, Attractions, Leisure, Culture, Support Systems, and Hospitality. In addition, the investigation observes that of the identified dimensions of perceived meaningfulness, the spiritual and societal dimensions contribute more to perceived meaningfulness than the physical well-being aspect. Further, the exploration estimated the theoretical framework developed using structural equation modelling and established the mediating role of perceived meaningfulness in developing visitor loyalty from In-loco Destination Image. The studys observations helped identify three positioning approaches, namely objective, subjective, and combined, offering suggestions to destination marketers to effectively reposition Indian destinations. 2022 Informa UK Limited, trading as Taylor & Francis Group. -

Despeckling of Ultra sound Images using spatial filters - A Fusion Approach
Ultra sound images are normally affected by speckle noise which is typically multiplicative in nature. This study proposes different fusion based despeckling methods for ultra sound images. The output of existing spatial domain despeckling methods viz. Lee filter, Bayesian Non Local Means (BNLM) filter and Frost filter are fused pairwise. Fusion is implemented in two steps, first an inter-scale stationary wavelet coefficient fusion followed by an intra-scale wavelet coefficient fusion. Analysis of these projected despeckling strategies are conducted using metrics like Peak Signal to Noise Ratio (PSNR), Equivalent Number of Looks (ENL), Structural Similarity Index (SSIM) and Universal Image Quality Index (UIQI). The results show that the performance of fusion based methods is better than the respective individual filters for despeckling ultra sound images. 2019 IEEE. -

Designing in situ nanostructured MWCNT-phloroglucinol modified webs for electrochemical-based dual screening of stress biomarkers
Phloroglucinol (PG), or benzene 1,3,5-triol, is an essential phenolic compound and a vital tannin. In this study, we developed a tannin-phloroglucinol (PG) derived redox mediator for the detection of glutathione (GT) and H2O2 on a glassy carbon electrode (GCE) modified with a multiwalled-chitosan composite. The PG redox platform was prepared using a cyclic voltammetric approach in pH 7 aqueous buffer media without any additional surfactant/chemical moieties. A highly stable, fouling-free surface confined redox characteristic was observed at an apparent electrode potential of E0? = ?0.196 V (A1/C1) and 0.05 V (A2/C2) vs. Ag/AgCl was observed. The as-prepared electrochemical platform achieved an ultra-low limit of detection (LOD) for glutathione (GT) of 0.16 M and LOQ of 2.08 M using a sustainable platform. In addition, it exhibited high selectivity for GT in the presence of various interfering analytes. In addition, the modified platform was extended to hydrogen peroxide (H2O2) sensing at ?0.196 V vs. Ag/AgCl with a LOD of 5.4 M in PBS buffer media at v = 10 mV s?1. The GCE/MWCNT-Chit@PG-Redox demonstrated robust performance in a proof-of-concept experiment for analyzing GT and H2O2 in real samples using a standard addition approach with good recovery values.
