    (Springer, 2023-07-29T00:00:00) Abbas, Gazy; Farooq, Umar; Singh, Parvinder; Khurana, Surinder Singh; Singh, Paramjeet
    With the rapid advancement in technology, the constant emergence of new applications and services has resulted in a drastic increase in Internet traffic, making it increasingly challenging for network analysts to maintain network security and classify traffic, especially when encrypted or tunneled. To address this issue, the proposed strategy aims to distinguish between regular traffic and traffic tunneled through a virtual private network and characterize traffic from seven different applications. The proposed approach utilizes various ensemble machine learning techniques, which are efficient and accurate and consume minimal computational time for training and prediction compared to conventional machine and deep learning models. These models were applied for both the classification and characterization of network traffic, deriving efficient results. The extreme and light gradient boosting algorithms performed well in multiclass classification, while AdaBoost and Light GBM performed well in binary classification. However, when all the datasets were merged and categorized into two classes and various feature engineering methods were applied, the proposed system achieved an accuracy of more than 99%, with minimal error scores using light GBM with min�max scaling over stratified fivefold, thereby outperforming all existing approaches. This research highlights the efficiency and potential of the proposed model in detecting network traffic. � 2023, The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd.

    (Taylor and Francis Ltd., 2023-09-12T00:00:00) Singh, Yogesh; Kumar, Niraj; Kulkarni, Swanand; Singh, Satwinder; Thareja, Suresh
    Aldose Reductase 2 (ALR2), a key enzyme of the polyol pathway, plays a crucial role in the pathogenesis of diabetic complications. Quinoxaline scaffold-based compounds have been identified as potential ALR2 inhibitors for the management of diabetic complications. In the present work, molecular dynamic simulation studies in conjugation with pharmacophore mapping and atom-based 3D-QSAR were performed on a dataset of 99 molecules in comparison with Epalrestat (reference) to mark the desirable structural features of quinoxaline analogs to generate a probable template for designing novel and effective ALR2 inhibitors. The most potent compound 81 was subjected to MD simulation studies and found to be stable, with better interactions with the binding pocket as compared to Epalrestat. The MM-GBSA and MM-PBSA calculations showed that compound 81 possessed binding free energies of ?35.96 and ?4.92 kcal/mol, respectively. Atom-based 3D-QSAR yielded various pharmacophoric features with excellent statistical measures, such as correlation coefficient (R 2 value), F-value (Fischer ratio), Q 2 value (cross-validated correlation coefficient), and Pearson�s R-value for training and test sets. Furthermore, the pharmacophore mapping provided a five-point hypothesis (AADRR) and docking analysis revealed the active ligand-binding orientations on the active site�s amino acid residues TYR 48, HIE 110, TRP 111, and TRP 219. The results of this study will help in designing potent inhibitors of ALR2 for the management of diabetic complications. Communicated by Ramaswamy H.

    Detection of content-based cybercrime in Roman Kashmiri using ensemble learning
    (Springer, 2023-09-25T00:00:00) Farooq, Umar; Singh, Parvinder; Khurana, Surinder Singh; Kumar, Munish
    The official language of Kashmir, Kashmiri language or Koshur, is spoken by more than 7 million people, yet its content-based cybercrime detection remains unexplored in theoretical and experimental research. Furthermore, the absence of programming libraries for sentimental analysis and a benchmark corpus has impeded advancements in this field. Challenges persist in working with diverse scripts of Kashmiri, including Perso-Arabic, Sharada, Devanagari, and Roman. Detecting cybercrime in this language is challenging due to its complex morphological nature, lack of resources, scarcity of annotated datasets, and varied linguistic characteristics, emphasizing the importance of overcoming these obstacles to develop effective detection systems. This paper attempts to detect content-based cybercrime in Roman Kashmiri script, extensively utilized on online platforms like social media, chat rooms, emails, etc., by the Kashmiri community. A well-balanced and meaningful dataset, the first of its kind in this context, is compiled, incorporating positive and negative comments, and three strategies were employed for analysis. The findings reveal that the Tf-Idf Vectorizer outperforms other tokenization methods (Count Vectorizer and Tf-Idf Transformer), bi-gram notation exhibits superior performance compared to one and tri-gram notations, and the XGBM proves to be the most effective in terms of evaluation metrics. Leveraging these strategies, Python applications were developed for text classification, successfully distinguishing cyberbullying (unsafe) from non-cyberbullying (safe) instances, with the XGBM exhibiting exceptional accuracy using the Tf-Idf Vectorizer with bi-gram, a Bag of Words, and lexical features. This pioneering research underscores the urgent need for content-based cybercrime detection advancements in the Kashmiri language, paving the way for effective detection systems to address language-specific challenges and promote a safer online environment for the Kashmiri community. Furthermore, this research opens new avenues for further advancements in detecting and preventing cybercrime in Kashmiri and potentially in other languages lacking robust cybercrime detection methodologies. � 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

    DL-2P-DDoSADF: Deep learning-based two-phase DDoS attack detection framework
    (Elsevier Ltd, 2023-09-26T00:00:00) Mittal, Meenakshi; Kumar, Krishan; Behal, Sunny
    In today's tech-driven world, while Internet-based applications drive social progress, their architectural weaknesses, inadequate security measures, lack of network segmentation, unsecured IoT devices etc., offer ample opportunities for attackers to launch a multitude of attacks on their services. Despite numerous security solutions, the frequent changes in the methods employed by attackers present a challenge for security systems to stay up to date. Moreover, the existing machine learning approaches are confined to known attack patterns and necessitate annotated data. This paper proposes a deep learning-based two-phase DDoS attack detection framework named DL-2P-DDoSADF. The proposed framework has been validated using the CICDDoS2019 and DDoS-AT-2022 datasets. In the first phase, Autoencoder (AE) has been trained using the legitimate traffic and threshold value has been set using Reconstruction Error (RE). The test data comprising legitimate and attack traffic has been used to validate the proposed approach efficacy. The initial phase entails utilizing a trained AE model to enable the passage of predicted legitimate traffic through the network. In contrast, the predicted attack traffic proceeds to the second phase to classify the type of attack it represents. The performance and efficacy of various deep learning approaches: Deep Neural Network (DNN), Long Short-Term Memory (LSTM) and Gated Recurrent Units (GRU) are compared as part of the second phase. The autoencoder displayed an accuracy level of 99% in detecting both datasets in the initial phase. It has been observed that the DNN produced an overall accuracy of 97% and 96% for the CICDDoS2019 and DDoS-AT-2022 datasets, respectively, for multiclass classification. The DNN model performed better than LSTM and GRU models in the second phase. � 2023 Elsevier Ltd

    Revolutionize AI Trading Bots with AutoML-Based Multi-timeframe Bitcoin Price Prediction
    (Springer, 2023-06-27T00:00:00) Khurana, Surinder Singh; Singh, Parvinder; Garg, Naresh Kumar
    Multi-timeframe analysis/prediction provides essential information to traders. It gives a broader perspective of market trends and is used to identify significant levels of support and resistance. This will help traders/trading bots in making trading decisions. The majority of current studies focused on forecasting the closing price of daily candlesticks or high-frequency time frames, such as those of 1�min or 5�min. For artificially intelligent trading bots focusing on swing trading, price prediction related to other time frames is very significant. In this research, we present a study on developing a model to enable artificial intelligent-based trading bots to predict price components (open, high, low, and close prices) of the next 30-min, 1-h, and 4-h candlesticks of Bitcoin price. The study used two Auto-Machine Learning libraries: Tree-Based Pipeline Optimization Tool (TPOT) and AutoSklearn, to find the most suitable model for the task. The models are trained on historical price data of Bitcoin, and technical indicators are computed on these data. The performance of the trained models is evaluated in terms of R2 Score (Coefficient of Determination), Mean Absolute Error (MAE), and Mean Absolute Percentage Error (MAPE). The results showed that TPOT outperformed AutoSklearn library for all three time frames. It predicted all price components of 30-min candlestick with R2 Score of 0.999. � 2023, The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd.

    Thyroid cancer continues to exhibit a rising incidence globally, predominantly affecting women. Despite stable mortality rates, the unique characteristics of thyroid carcinoma warrant a distinct approach. Differentiated thyroid cancer, comprising most cases, is effectively managed through standard treatments such as thyroidectomy and radioiodine therapy. However, rarer variants, including anaplastic thyroid carcinoma, necessitate specialized interventions, often employing targeted therapies. Although these drugs focus on symptom management, they are not curative. This review delves into the fundamental modulators of thyroid cancers, encompassing genetic, epigenetic, and non-coding RNA factors while exploring their intricate interplay and influence. Epigenetic modifications directly affect the expression of causal genes, while long non-coding RNAs impact the function and expression of micro-RNAs, culminating in tumorigenesis. Additionally, this article provides a concise overview of the advantages and disadvantages associated with pharmacological and non-pharmacological therapeutic interventions in thyroid cancer. Furthermore, with technological advancements, integrating modern software and computing into healthcare and medical practices has become increasingly prevalent. Artificial intelligence and machine learning techniques hold the potential to predict treatment outcomes, analyze data, and develop personalized therapeutic approaches catering to patient specificity. In thyroid cancer, cutting-edge machine learning and deep learning technologies analyze factors such as ultrasonography results for tumor textures and biopsy samples from fine needle aspirations, paving the way for a more accurate and effective therapeutic landscape in the near future. � 2023 The Author(s)
