Enhancing Angle Modulation Using Fractional Calculus: Theory and Performance Analysis
Angle modulation originally forms part of the backbone of the telecommunication and signal processing, where current studies are being carried out to improve its susceptibility to noise interference. This paper aims to analyze the possibility of the application of fractional calculus for optimization of angle modulation, as a requirement for development of enhanced and flexible communication networks. The main purpose of this study is to design and model new angle modulation technique which are Fractional Phase Modulation (FPM) and Fractional Frequency Modulation (FFM) by using fractional calculus. A generalized form of angle modulation and an introduction to the use of fractional calculus was proposed and a mathematical analysis of FM and FFM detectors was done. In evaluating the findings, the interaction between the fractional order of ? and some performance parameters like Signal-to-Noise Ratio (SNR) and Figure of Merit (FoM) was also considered. It has been shown that FPM and FFM detectors also show high SNR and FOM performance, and when ? is replaced. The FPM detector demonstrated a steady trend and increased from SNR 0 to 1 when the ? was diverse, while the FFM detector had a huge increase in SNR from ?=-0.9 to 0. These results indicate that the angle provides additional benefits in partial stones, signaling purity and system flexibility for the modulation technique. Thus, the ability to achieve better stability in communication for modulation techniques indicates the ability to achieve better stone purity and system flexibility for modulation techniques. Since partial order ? can be adjusted to fit the application, the proposed method shows interesting applications in many communication settings, especially when the signal is noisy or dynamic. 2025, School of Electrical Engineering and Informatics.

Association Between Early Maladaptive Schemas and Developmental Crisis Among Young Adults: Mediating Role of Cognitive Flexibility
Background: Analysing the relationship between early maladaptive schemas (EMSs) and developmental crises is critical for advancing targeted interventions; however, the psychological mechanisms underpinning these processes remain largely unexplored. Growing evidence indicates that cognitive flexibility potentially acts as a mediator in this relationship. Purpose: Grounded in the schema therapy conceptual model by Young et al. (2003), the present study investigates the mediating effect of cognitive flexibility between EMS and developmental crisis, offering insights for cognitive-based interventions. Method: A total sample of 200 participants (male = 87, female = 113), aged 1825 years (M = 20.4, SD = 1.84), were recruited using purposive sampling. The Young Schema QuestionnaireShort Form (YSQ-S2), the Developmental Crisis Questionnaire (DCQ) and the Cognitive Flexibility Scale (CFS) were administered. Result: Pearson productmoment correlation revealed a positive association between EMS and developmental crises, with the most robust relationship observed for the Disconnection and Rejection domain of EMS. Mediation analysis revealed that cognitive flexibility partially mediates the relationship between EMS 1 and developmental crises, while fully mediates the relationship for EMS 2 and 5 with developmental crises, buffering their impact, thereby reducing developmental crises among young adults. Conclusion: These findings deepen our knowledge of how cognitive patterns influence developmental challenges, delivering practical implications for creating targeted, schema incorporated interventions to strengthen resilience and support mental health in young adults.

Removal of high concentration Cr (VI) through the synergetic effect of CuInS?/Ni-MoS?/NrGO Z-scheme heterojunction and Deinococcus radiodurans R1 nano-biohybrid system
The efficient removal of high-strength hexavalent chromium [Cr (VI)] from industrial effluents continues to be a significant challenge. This study introduces a nano-biohybrid approach that combines a CuInS?/Ni-MoS?/NrGO Z-scheme heterojunction with live biomass of Deinococcus radiodurans R1 under anaerobic conditions. This combination aims to enhance the reductive sorption of Cr (VI). A Z-scheme heterojunction composed of CuInS?, Ni-MoS?, and NrGO was synthesized using the hydrothermal technique. The structural and morphological properties of the synthesized nanomaterials (NMs) were examined through various techniques, including XRD, FT-IR, UV-VIS DRS, FE-SEM, EDX, PL, XPS, Raman spectroscopy, and Mott-Schottky analysis. The CuInS?-Ni-MoS?-NrGO nanocomposite achieved nearly 97% removal of Cr (VI) at an initial dose of 50 mg/L within 3 h, which is almost three times more effective than the individual NMs CuInS?, Ni-MoS?, and NrGO. Further, applying the nano-biohybrid synergetic system enabled complete removal of Cr (VI) even at 200 mg/L, enhancing its removal capacity by 2.5-fold higher than the bare nanocomposite. The Langmuir isotherm model fits well with the experimental data, confirming homogeneous monolayer adsorption with a maximum Cr (VI) reductive sorption capacity of 333 mg/g. The intra-particle diffusion model analysis indicated that external mass transfer plays a dominant role in controlling the overall Cr (VI) sorption process. Furthermore, kinetic studies revealed that the Cr (VI) removal follows a pseudo-second-order model, suggesting chemisorption as the primary mechanism. The nanocomposite exhibited strong reusability, maintaining 86.5% Cr (VI) removal efficiency over 4 cycles. These results highlight the potential of nano-biohybrid systems as an efficient strategy for Cr (VI) remediation from contaminated wastewater. 2026 Elsevier B.V. -
AeroGlan: A Smart and Sustainable Plant Species Estimator For Organic And Localized Air Filtering
Introduction: Human health is significantly compromised by air pollution, especially by local air quality. The majority of our society spends their lives in a confined geographical location, which if subjected to air pollution can expose them to long-term air contamination. It is also possible that poor air quality can pose serious health risks, especially to susceptible individuals thereby impacting their lifestyle. Air quality can be improved with appropriate plantation, but they are underutilized. Various air purification devices have been developed in response to the ever-increasing air pollution level. Methods: However, artificial means of air purification are not very viable in terms of cost, accessibility to society, and reliable tools to purify air. This research integrates traditional solutions with modern technology to counter air purification by selectively using plant species and placing them in desired locations suitable for urban settings. The study aims to measure the constituents of various air pollutants spanning across regions to identify and accumulate pollution data using IoT-based smart devices, remit, and feed this information to cloud-based storage for further processing. In addition, advanced predictive intelligence is utilized to determine the plant species that can suffice the need for air purification through organic means in a given geographical zone resulting in enhancement of Air Quality (AQ), with minimal cost, prolonged shelf life, future proof and non-detrimental consequences. Results: Implementation outcome gives a promising outcome. Accurate readings of various air pollutants are aggregated. Suitable trees are identified to tackle these pollutants and their absorbing capacity is determined. Various predictive methods are employed and the random forest model recorded the best results. The sensory units of the model successfully captured the pollutant data and any major fluctuations were reported. The prediction pipeline recorded a mean precision, recall, and f-score value of about 0.95, 0.92, and 0.94 respectively while the mean accuracy of 0.965 was also noted. The observed training and validation accuracy with our model were 0.96 and 0.93 respectively. Conclusion: Hence, the proposed AeroGlan model may be locally applied as an air pollutants monitoring device and also to suggest suitable plant species required to counter air contamination in that locality. 2025, Bentham Science Publishers -

The image is a composition of many pixels. These pixels include two pieces of information: coordinate or position and intensity value. The image includes several objects; extracting the crucial objects from the image is critical. Based on the similarity of patterns, classes, groups, and segments of contained objects in the image can be created. Assigning the labels to the pixels is necessary to make the image more informative for analyzing features and decision-making. This study addresses segmentation techniques and classifying images pertaining to remote sensing images. Thereafter, Land Use Land Cover (LULC) mapping is discussed, which classifies the remote sensing images. 2025 Bentham Science Publishers. All rights reserved. -
Inhibitory potential of ferula assafoetida extract on L-type calcium channel protein revealed by zebrafish studies and molecular docking
Ferula assafoetida is a part of many herbal formulations and hence it is pertinent to check the safety of its components specially to growing embryos. Zebrafish (Danio rerio) is considered to be one of the best models to study human embryonic development and metabolic pathways as its genome is fully sequenced and it possesses easily detectable developmental properties. In present study, the embryos of Danio rerio were treated with different concentrations of methanolic extract of Ferula assafoetida (MEFA) and its effects were checked at different post fertilization periods. Decreased heart beat rates, shrinkage of the chorion wall and other developmental abnormalities leading to the death of the embryos were observed. The methanolic extract of Ferula assafoetida was subjected to GC-MS to determine the different compounds present. Cardiotoxicity of these compounds were studied as it is one of the important factors for the retraction of a drug from the market. Molecular docking studies with L-type calcium channel (LTCC), a protein important for cardiac functioning, showed strong binding to the phytochemicals in the extract, with the maximum binding affinity observed with 26-hydroxycholesterol. The study proves that the methanolic extract of Ferula assafoetida contains phytochemicals which have the potential to cause cardiotoxicity in zebrafish embryos by interfering with the functions of LTCC possibly leading to arrhythmia. Altogether, our data suggest that the usage of these extracts in drug formulations should be done with caution. This is also indicative of the possible cytotoxic effect of the extract which could be tapped in the search for anticancer drugs. 2021 Chemical Publishing Co.. All rights reserved. -

Areas of further enhancements have also been identified and presented. 2019 Institute of Advanced Engineering and Science. -
Analysis of students' preferences for teachers based on performance attributes in higher education
Faculty evaluation is widely used not only for the appraisal of their performance, but also for curriculum innovation and development. There are many techniques to perform faculty evaluation. But these techniques do not address all the factors essential for evaluating a faculty. These evaluations are subjective in nature and found to be controversial as students' expectations vary. This hinders the main motive of faculty evaluation. To overcome this problem, there is a need to identify a suitable method to perform faculty evaluation. In this paper, the Conjoint Analysis, a mathematical statistics technique is used to analyze the major aspects that the students are expecting from their faculty. This technique increases the fairness in the appraisal process so that teaching can be made fun and effective. This research is a novel attempt that applies conjoint analysis to identify the major aspects of teaching in students' perspective. The proposed idea can be adapted to any domain where the customers' choice is valued particularly in Cloud computing services. 2019 Mithula G P, Arokia Paul Rajan R. -
Fake News Detection and Classify the Category
A new type of disinformation has emerged: fake news, or untrue stories that have been presented as actual occurrences. We can no longer tell whether the information is true from fraudulent since so much information is published on social media these days. Artificial intelligence algorithms are helpful in resolving the fake news identification issue. In the field of natural language processing, fake news identification is a crucial yet difficult issue (NLP). In this article, we discuss similar duties as well as the difficulties associated with finding bogus news. Based on these findings, we suggest intriguing avenues for future study, such as developing more accurate, thorough, fair, and useful detection models. The average public's life is impacted by mass media since it happens regularly. Because of this, news stories are written that are somewhat true or even entirely untrue. Using online social networking sites, people deliberately promote these fake goods. It is crucial to decide whether the news is false owing to its potential to have detrimental social and national effects. The false news identification process made use of many criteria, including the headline and body content of the news piece. The suggested method works effectively in terms of producing results with excellent accuracy, precision, and memory. Comparing all the models employed in this study, it was discovered that Distillbert and multinomial nae bayes models perform better than Logistic and others ml models. The credibility of the story may be evaluated using a larger dataset for better results and additional variables like the author and publisher of the news. Grenze Scientific Society, 2023. -
Fake News Detection and Classify the Category
Everyone depends on numerous sources of E-news in today's world when the internet is ubiquitous. Online content abounds, especially social media feeds, many of which are unreliable and may not always be factual. For people to utilise social media platforms like Facebook, Twitter, and others, fake news is a topic that may be studied through Natural Language Processing techniques. Using ideas from natural language processing and machine learning applied to social media, our goal in this work is to conduct categorization of different news items that are available online. Our intention is to empower the user to utilise NLP (Natural Language Processing) methods to identify 'fake news,' which refers to misinformed material that may be categorised as genuine or false using software like Python. The model focuses on identifying false news sources based on several articles from a website, categorising the news as false or true, and determining its veracity using unreliable sources like scikit-learn and NLP for textual analysis of the website distributing the news. When a source is identified as a publisher of false news, which can be predicted with high vectorization and also suggested using the Python scikit-learn module to do tokenization and feature development, biased viewpoints may be identified and categorised in any subsequent articles from that source. 2022 IEEE. -

Adsorption and storage of hydrogen- A computational model approach
Due to the imperative global energy transition crisis, hydrogen storage and adsorption technologies are becoming popular with the growing hydrogen economy. Recently, complex hydrides have been one of the most reliable materials for storing and transporting hydrogen gas to various fuel cells to generate clean energy with zero carbon emissions. With the ever-increasing carbon emissions, it is necessary to substitute the current energy sources with green hydrogen-based efficient energy-integrated systems. Herein, we propose an input-output model that comprehends complex hydrides such as lithium and magnesium alanates, amides and borohydrides to predict, estimate, and directly analyse hydrogen storage and adsorption. A critical and thorough comparative analysis of the respective complex hydrides for hydrogen adsorption and storage is discussed, elucidating the storage applications in water bodies. Several industrial scale-up processes, economic analysis, and plant design of hydrogen storage and adsorption approaches are suggested through volumetric and gravimetric calculations. 2024 Elsevier Inc. -

Impact of COVID-19 and Social Distancing Measures on Married Women: A Qualitative Enquiry
Considering the World Health Organizations declaration of COVID-19 as a pandemic, governments worldwide implemented lockdowns and social distancing measures to contain the spread. Despite these critical measures, the pandemic exacerbated gender inequality, particularly impacting women. With schools and workplaces closed and heightened concerns for family members health, women shouldered increased family responsibilities, leading to numerous physical and psychological health challenges. Married women, in particular, faced amplified burdens. This study aims to delve into the experiences of married women during the pandemic. Twenty married women within the age range of 2245 years residing in the northern part of India were telephonically interviewed about their experiences during the COVID-19-induced lockdown. The interviews recordings were transcribed manually and analysed using thematic content analysis. The emerging themes -emotional and psychological impact, social impact, workload impact, and coping mechanisms -shed light on both the positive and negative outcomes of the pandemic. The results revealed that both working and non-working married women encountered emotional, psychological, and social challenges such as anxiety, social isolation, increased intimacy, and workfamily conflict due to heightened domestic responsibilities resulting from the confinement of each family member at home. However, women reported that habituation and forced adjustments became their primary coping mechanisms. 2025 selection and editorial matter, Shalini Mittal, Tushar Singh, Harleen Kaur, Rahul Varma, Sreeja Das, Yogesh Kumar Arya, Sunil K.

Spectrometric Analysis of Decrease in Sodium Dodecyl Sulfate (SDS) Concentration by Klebsiella Species Using the Stains-All Dye
Abstract: Sodium dodecyl sulfate (SDS)-degrading bacteria were isolated from soil and water samples from multiple locations using basal media with 0.05% SDS as the only carbon source. The bacteria were identified using 16S rRNA sequencing and deposited in the NCBI database with specific accession numbers and strain name. There were six bacteria iidentified as Klebsiella variicola MSK86, Klebsiella sp. MSK86, K. quasipneumoniae MSK86, and three K. pneumoniae strains, MSK86, MSK25, and NET12. The potential for decrease in SDS concentration by the bacteria was assessed using Stains-all. The SDS standard graph was plotted with different SDS concentration of 0 to 0.06%. The SDS-Stains-all complex exhibited a peak with maximum absorbance at 440 nm. The absorbance of the bacteria-inoculated samples was monitored at 440 nm on every 24 h until the sixth day of incubation. The decrease in concentration of SDS in the medium on day 6 of incubation by K. pneumoniae MSK86, K. variicola MSK86, and Klebsiella sp. MSK86 was found to be 86, 84, and 84%, respectively. K. pneumoniae NET12 demonstrated 76% of decrease. K. pneumoniae MSK25 and K.quasipneumoniae MSK86 were able to survive in the SDS medium, with decrease of 20 and 40%, respectively. The focus of this investigation was finding bacteria that can breakdown SDS, that may contribute to the decrease in the amount of detergent pollution in water. Pleiades Publishing, Ltd. 2025. -
Rise of Populism in Northeast India: A Case of Assam
A blend of historical and contemporary forces has shaped populism in India. The Congress governments shortcomings (20042014), marked by dynastic politics and corruption, paved the way for the rise of populism, particularly under the Bharatiya Janata Party (BJP), which capitalized on anti?elite sentiment. Narendra Modis leadership, characterized by Hindu nationalism and a development agenda, has significantly altered Indias political landscape. This study focuses on the rise of populism in Northeast India, specifically in Assam, where populist movements and leaders have increasingly influenced the socio?political environment. It explores the socio?economic conditions and identity politics that have driven the growth of populist ideologies, often leading to the marginalization of ethnic minorities. By analyzing key political events, movements, and policies, the research seeks to uncover the root causes of populism in Assam and its impact on democracy, social cohesion, and regional stability. Employing a qualitative methodology that includes political speeches, media analysis, and empirical evidence, the study examines how political leaders in Assam have mobilized regional and ethnic sentiments for electoral gains, further exacerbating ethnic marginalization. The article aims to understand the catalysts and consequences of populist governance in Assam, offering insights into the broader trend of populism in Northeast India and its future trajectory. 2024 by the author(s). -
Mamaearth: from a mothers dilemma to a multi-crore brand
Learning outcomes: The case study has several objectives: to gauge the evaluation of the direct-to-consumer industry in the economy of India, to analyse the competition of the brands, to ascertain the evolution of smaller direct-to-consumer (DTC) brands on the purchasing capacity of consumers, to analyse challenges in branding in Tier 2 and 3 cities and to evaluate the strategic branding decisions of Mamaearth. Case overview/synopsis: During her pregnancy, Ghazal Alagh and her husband Varun Alagh, the co-founders of Mamaearth, were looking for some good and natural products for their babys skincare. However, she could not find products that were 100% safe. Hence, as a concerned mother, she started using a few hands-on home remedies for her baby, which were 100% organic, and then the idea clicked to her to start a baby care brand named Mamaearth, which later also included personal care products. The company started as a DTC/internet-first brand in 2016, which only used to sell products online without any intermediaries when it was still trying to make its way in the market and was aware of the stiff competition by giants such as Hindustan Unilever and Proctor & Gamble, who were ruling the market for decades. When the COVID-19 pandemic hit, the market saw a shift in consumer buying patterns. There was greater use of e-commerce touch points for shopping, as various digital platforms such as the official site of products, social media and mobile platforms were used by consumers during the pandemic, leading to digitalization in buying and digitalization of consumer shopping journey. These technology platforms were expected to play a substantial role in reaching and creating consumer awareness, transaction and retention post-COVID according to reports by Deloitte 2020. Moreover, such a shift in behaviour amidst the COVID-19 pandemic shot up sales of this DTC brand and made itself the big shot it is today, where they were looking to get into an initial public offering in just seven years of its launch. They re-evaluated their strategy, which helped them become the biggest brand in no time. Complexity academic level: This case study is suitable for Doctor of Philosophy students.
