The Role of IOT in Creating SC'S through Ultra Fast Updation of the Status for Accurate Action Plan
The idea of a smart city includes the merging of technologies and advances aimed at improving urban efficiency, scientific progress, the preservation of the environment, and social inclusion. Coined in the year 2000, the term became widely used in politics, business, management, and urban planning groups to drive tech-based changes in urban areas. It reacts to the difficulties posed by postindustrial communities handling problems such as pollution to the environment, demographic changes, population growth, health care monetary crises, and resource shortages. Beyond technical answers, the smart city idea includes non-technical innovations for healthy urban life. Particularly encouraging is the application that uses Internet of The circumstances (IoT)based sensors in healthcare, applying machine learning for effective data management. This paper discusses the application of AI-powered Ai and Wireless Sensor Networks, more commonly known as the field of health care, acting as a basic study to understand the impact of IoT in smart cities, especially in healthcare, for the sake of future research. 2024 IEEE. -
Post-Listing Performance of IPOs in Indias Financial Services Sector (20212024): An Industry-Specific Empirical Study
The number of initial public offerings (IPOs) made in the Indian financial services sector between 2021-2024 has increased, due to heightened investor activity. Although the volume of IPO issues has increased, there is limited research on their short-term performance, particularly in the context of industry-specific analysis. This paper will evaluate the performance of IPOs that issue financial services companies in India during the listing period of 20 days using the event study methodology. The daily returns of IPOs and the index (NIFTY 50) are taken to compute market-adjusted short-run performance (MASRP), wealth relative (WR), abnormal returns (AR), and cumulative abnormal returns (CAR). The regression analysis shows that only oversubscription can have a significant effect on the revenue of an IPO in terms of returns. This research has added value by using sector-specific evidence, which may be useful to investors, issuers, and regulators when evaluating short-run IPO efficiencies. 2026 by IGI Global Scientific Publishing.

Leveraging QSPR-guided ZIF selection for MWCNTs/ZIF-8 platforms for electrochemical immunosensing of lactoferrin
This study presents a data-driven workflow integrating quantitative structureproperty relationship (QSPR) modelling with Monte Carlo (MC) adsorption simulations to guide zeolitic imidazolate framework (ZIF) selection for lactoferrin (LF) immunosensing.MC simulations calculated adsorption energies (Eads) of LF across 27 ZIFs, represented using MOFid/MOFkey-encoded SMILES notation, enabling construction of a predictive QSPR model (top-performing model: PLS, R2=0.891, Q2=0.888). The model successfully ranked ZIFs according to predicted LF affinity, with ZIF-8 emerging as the optimal candidate based on computational predictions, structural robustness, and synthetic accessibility. Following computational validation through molecular docking, ZIF-8 was integrated with multiwalled carbon nanotubes (MWCNTs) on a glassy carbon electrode (GCE), enabling noncovalent immobilization of anti-LF antibodies. Electrochemical measurements performed using square-wave voltammetry (SWV) with a ferri/ferrocyanide [Fe(CN)6] 3?/4- redox probe demonstrated a linear response over 1060ng/mL LF (R2=0.994), a limit of detection (LOD) of 4.78ng/mL, and recoveries of 95105% in spiked milk samples with reproducibility ?8% RSD (n=3). Shelf-life studies showed 74% signal retention after four weeks of storage at 4C. Electrochemical analysis revealed a synergistic enhancement of charge transfer (Rct) in the MWCNTs/ZIF-8 composite (0.572k? vs. 12.79k? for bare GCE). This work demonstrates a transferable, computationally driven framework for screening framework materials in MOF/ZIF-based biosensors, bridging predictive materials design with experimental device fabrication for broad applications in clinical diagnostics and food quality monitoring. 2026 Published by Elsevier B.V. -
Engineered MOF-199 Modified Electrodes for Enhanced Electrochemical Immunosensing of Lactoferrin via Signal Amplification
The detection of lactoferrin (LF), an essential immunological and nutritional biomarker, demands highly sensitive analytical platforms for low-level detection. In this study, a label-free electrochemical immunosensing platform was constructed by immobilizing anti-lactoferrin antibodies (Anti-LF-Ab) on a multiwalled carbon nanotube and a metalorganic framework (MWCNT/MOF-199) nanocomposite-modified glassy carbon electrode (GCE). The synergy between MWCNTs and MOF-199 provided abundant active sites for antibody immobilization and enhanced electron transfer, yielding an eightfold current increase compared to bare GCE. Electrochemical analyses confirmed efficient charge transfer and stable antibody binding. Under optimized conditions, the immunosensor exhibited exceptional analytical performance with a low detection limit of 5.24 ng ml?1 and a quantification limit of 17.46 ng ml?1 across a wide detection range of 050 ng ml?1. The platform demonstrated strong analytical reliability, including excellent repeatability (RSD < 5%), reproducibility and operational stability over multiple measurement cycles for LF detection in food diagnostics. In addition, Monte Carlo simulations confirmed the stability of the layer-by-layer assembly, supporting the robustness of the engineered sensing interface. 2025 The Author(s).

Event-Triggered Polynomial Model Predictive Control for Multi-Agent Navigation
This paper proposes an event-triggered polynomial model predictive control method for collision-free point-to-point multi-agent navigation. In this control method, each control input to each agent is a polynomial whose coefficients are updated in an event-triggered manner. For each agent, we design an event-triggering rule that guarantees non-Zeno behavior of inter-event times. At each event, the controller updates the coefficients of the polynomial control law corresponding to a subset of agents by solving one or more finite horizon optimization problems. We also ensure feasibility of the optimization problems solved at each event. Through numerical simulations, we illustrate the results and compare the proposed method with other existing methods. 2025 IEEE. -
In silico studies of viral protein inhibitors of Marburg virus using phytochemicals from Andrographis paniculata
The Marburg virus is a causative agent of Marburg hemorrhagic fever, which was discovered in Marburg, Germany, in 1967. It is a highly contagious and fatal disease transmitted by body fluids. The reservoir host is African fruit bats. Currently, there is no vaccine available to control this disease. Medicinal plants possess many phytochemicals of great therapeutic value. Many have antiviral properties and have been identified as promising drug molecules against various viral diseases proven with an in silico approach. The current research uses the in silico approach to identify the phyto-derived drugs from Andrographis paniculata to treat the Marburg virus. Twenty-four bioactive molecules from the A. paniculata plant were investigated against the targets VP35 and VP40 of Marburg viral proteins using the AutoDock Vina 1.1.2 tool. Out of 24 compounds, Andrographidine C, Andrographidine A, Andrographolactone, and 7-O-methylwogonin showed best docking scores for the target VP40 dimer while Bisandrographolide A, Luteolin Andrographolide, and Andrographiside showed best docking scores with VP35 protein. To determine the druglikeness, pharmacokinetic and pharmacodynamic properties and toxicity for each targets highest docking score compound was assessed using the Swiss absorption, distribution, metabolism, and excretion (ADME) and pkCSM tool. Andrographidine C and Andrographolide performed well in all the parameters of ADME and toxicity. These compounds are recommended as effective inhibitors of VP35 and VP40 of Marburg virus and potential antiviral drugs to treat the hemorrhagic disease. Furthermore, in vitro and in vivo studies can be used to examine the effectiveness and mode of action against the proteins of the Marburg virus. 2023 R. Hariprasath et al -
SILICON DEPLETION in the INTERSTELLAR MEDIUM
We report interstellar silicon (Si) depletion and dust-phase column densities of Si along 131 Galactic sight lines using archival observations. The data were corrected for differences in the assumed oscillator strength. This is a much larger sample than previous studies but confirms the majority of results, which state that the depletion of Si is correlated with the average density of hydrogen along the line of sight ( (H) as well as the fraction of hydrogen in molecular form ( f(H2)). We also find that the linear part of the extinction curve is independent of Si depletion. Si depletion is correlated with the bump strength (c3/RV) and the FUV curvature (c4/RV) suggesting that silicon plays a significant role in both the 2175 bump and the FUV rise. 2016.

Depletion studies in the interstellar medium
We report interstellar Si depletion and dust-phase column densities of Si along 131 Galactic sight lines using previously reported gas-phase Si II column densities, after correcting for the differences in oscillator strengths. With our large sample, we could reproduce the previously reported correlations between depletion of Si and average density of hydrogen along the line of sight () as well as molecular fraction of hydrogen (f(H2). We have also studied the variation of amount of Si incorporated in dust with respect to different extinction parameters. With the limitations we have with the quality of data, we could find a strong relation between the Si dust and extinction. While we cannot predict the density dependent distribution of size of Si grains, we discuss about the large depletion fraction of Si and the bigger size of the silicate grains. 2013 AIP Publishing LLC. -
Enhanced power quality control of a photo voltaic power plant integrated with multiple electric vehicle
As there is a great need for high-quality electricity on the distribution side, distribution side generation (DSG) has become increasingly important. The increased weight of EVs on the distribution side is the cause of this. There are numerous power quality mitigation techniques employed to address this type of issue, but many of the solutions suggest the usage of a separate device, such as an active power filter. But while construction the DSG the solution to this problem may be addressed using the proposed solution in this paper. Power quality (PQ) problems are being caused by the grids integration of Photo-Voltaic (PV) and its application to all connected loads. With the aid of Direct Quardrature (DQ) controller and Multicarrier Space Vector Pulse Width Modulation (SVPWM) technology, the overall power quality disturbance is decreased. A Simulink model for the PV-EV-Grid system was built to measure voltage and current Total Harmonic Distortion (THD) percentages under linear, non-linear, and Plug in Hybrid Vehicle (PHEV) load situations. The model shows that the THD values are well within the IEEE 519. Indian Academy of Sciences 2024. -

The combination of Photovoltaic (PV) systems and Electric Vehicles (EVs) holds enormous promise in an era characterized by growing environmental consciousness and sustainable energy solutions. PV technology is a clean, sustainable energy source that produces electricity by utilizing solar energy. Concurrently, EVs electrification of transportation is a critical step in the direction of lower greenhouse gas emissions and more energy efficiency. Through the use of advanced control systems, this research aims to push the boundaries of current practice in the area of PV and EV integration. Specifically, it focuses on the Icos? controller and dq controller to regulate voltage, minimize Total Harmonic Distortion (THD), and facilitate bidirectional power flow. A thorough Simulink model is created, simulating a complicated PV-EV-grid system, in order to evaluate the effectiveness of different control mechanisms. This model accommodates the unique characteristics of Plug-in Hybrid Electric Vehicles (PHEVs) and enables a detailed assessment of the percentages of voltage and current THD under different operating situations. It can handle both linear and non-linear loads. Most importantly, the studys findings showthattheTHDvaluesmeetthestrictrequirementsoutlinedinIEEE519, highlighting the efficiency of the integrated control approaches. The research not only contributes to the advancement of PV and EV technologies but also paves the way for grid-compatible, high-quality power distribution.

Power quality disturbance mitigation in grid connected photovoltaic distributed generation with plug-in hybrid electric vehicle
In the last twenty years, electric vehicles have gained significant popularity in domestic transportation. The introduction of fast charging technology forecasts increased the use of plug-in hybrid electric vehicle and electric vehicles (PHEVs). Reduced total harmonic distortion (THD) is essential for a distributed power generation system during the electric vehicle (EV) power penetration. This paper develops a combined controller for synchronizing photovoltaic (PV) to the grid and bidirectional power transfer between EVs and the grid. With grid synchronization of PV power generation, this paper uses two control loops. One controls EV battery charging and the other mitigates power quality disturbances. On the grid connected converter, a multicarrier space vector pulse width modulation approach (12-switch, three-phase inverter) is used to mitigate power quality disturbances. A Simulink model for the PV-EV-grid setup has been developed, for evaluating voltage and current THD percentages under linear and non-linear and PHEV load conditions and finding that the THD values are well within the IEEE 519 standards. 2023 Institute of Advanced Engineering and Science.

Stress analysis of the vertical tail skin joint and estimation of fatigue life due to fluctuating side loads
Vertical tail VT is one of the main components of the airframe. VT is attached with a rudder, which is the control surface, which is used for controlling the yawing motion of the aircraft. The deflection of the rudder introduces side load on the VT. Without rudder deflection, the aerodynamic load will not be applied to the VT. The load due to the deflection of the rudder is the major load for the VT. From a design point of view side, gust load is also important in transport aircraft. The present study is on a critical region with a riveted joint in the VT skin. A stiffened panel of the vertical tail with the spliced skin will be considered for the identification of the critical location. FEM will be used for the analysis of the component. In this study, loads of small transport aircraft will be considered. The maximum stress location and distribution of stresses on the stiffened panel are conducted by the FEM method. To obtain the mesh independent magnitude of stress, a refined local analysis is conducted. The tensile stresses on the skin are caused by the side loads of VT on the stiffened panel. Rivet holes are the stress concentration locations. The locations for fatigue crack initiation is the rivet holes. Fatigue damage estimation is calculated by the use of Miners rule. Fluctuating loads due to rudder deflection will be considered for damage calculation. SN data curve of the aluminium alloy material used for the VT skin will be considered for stress-based damage calculation. TJPRC Pvt. Ltd. -
Experiment investigations of effect of laminate thickness on flexural properties of GLARE and GFRP laminates
The study focuses on the fabrication of Glass Fiber Reinforced Aluminum (GLARE) laminates and evaluation of their flexural properties. Aluminum 2024 (T3) sheets were used for the fabrication of GLARE laminates along with E-glass fiber in the form of chopped strand mat and epoxy resin. Different thickness of aluminum sheets ranging from 0.2 mm to 3.5 mm was used to fabricate the GLARE laminates. Hand layup technique is used to bond together aluminum sheets and epoxy/E-glass fiber laminates under different configurations. The test specimens were prepared as per ASTM standards, and standard three-point bending test was carried out to evaluate different bending characteristics. An increase of 60% in load-bearing capacity was observed when aluminum sheet thickness was an increase from 0.2 mm to 0.35 mm. Similar The results were compared with similar glass fiber reinforced plastic (GFRP) laminates to analyze improvements, whereas, the maximum deflection of the laminate decreased. There were not many improvements in case of bending strength and bending modulus when aluminum sheet thickness was varied. Fracture surface analysis indicated three modes of failure namely, interfacial delamination, delamination bonding, and fiber breakage. When compared with glass fiber reinforced plastics of similar configuration, a substantial increase in bending strength was observed. 2018 IOP Publishing Ltd. -
Effect of face sheet on the flexural and tensile characteristics in GLARE laminates
The present study is carried out to study Glass Fibre Reinforced Aluminium Laminate (GLARE) structures and to evaluate their flexural and tensile properties. The GLARE specimens were fabricated using hand layup with vacuum bag moulding process wherein the aluminium sheets and E-Glass fibre woven mats of fixed thickness are bonded together by application of epoxy resins. Three different thicknesses of aluminium alloy (0.2 mm, 0.3 mm and 0.4 mm) Al-2024 T3 are used for the purpose of the study. The aluminium sheets are stacked together by application of epoxy resin between the sheets and are cured under a compression moulding machine under constant pressure. The overall thickness of the specimen is maintained constant for 2 mm. The samples were subjected to a three-point bending and tensile test as per ASTM D790 and ASTM D3039 standards, respectively, to evaluate their mechanical properties. The results indicate that the tensile strength of the composites is maximum for the specimen with aluminium 2024 T3 face sheet with a minimum thickness of 0.2 mm; however, with the increase in the thickness, the tensile strength is found to be decreasing. 2021 Engineers Australia. -
Digital transformation for business: Enablers, framework and challenges
Technology has disrupted many industries from the start of Industrialization era to the Industry 4.0 era. There has been an exponential growth in the technological front and people are talking about Industry 5.0. Digital transformation is a critical direction in which organizations will have to move toward in order to succeed in this competitive world. To make a smooth transition, firms must understand the basic building blocks of the digital transformation process and the key areas it touches upon namely customer experience, operational process and dynamic business models. Organizations will also have to identify the enablers of digital transformation which they can work on to smoothen the transformative process. Firms will also need the framework of digital transformation spelling out the roadmap for effective digital transformation. Firms on the urge to go for digital transformation will face numerous challenges in all the stages of implementation namely the initiation phase, the execution phase and the governance phase. A clear understanding of these challenges will help the firms to overcome or mitigate these challenges and be successful in their digital transformation process. 2023 by V. Harish, A.

Impact of hot rolling on the mechanical characteristics and microstructure of copper-based metal matrix composites reinforced with titanium carbide
Copper-based metal matrix composites reinforced with varying weight percentages (0, 2, 5, 7, and 10 wt%) of powdered titanium carbide (TiC) particles were successfully fabricated using stir casting, followed by hot rolling as a secondary processing route to enhance their mechanical performance. The microstructural evolution, phase characteristics, and mechanical behaviour of both as-cast and hot-rolled composites were systematically studied. Microstructural examination revealed a dendritic grain structure with non-uniform grain size distribution in as-cast composites, whereas hot-rolled composites exhibited a refined lath-shaped grain structure with uniform TiC particle distribution, attributed to the plastic deformation induced during rolling. XRD analysis confirmed the presence of high-intensity copper matrix peaks in hot-rolled composites and relatively stronger TiC peaks in as-cast composites due to the fragmentation of coarse reinforcement particles during rolling. Mechanical testing demonstrated that hot rolling significantly enhanced both hardness and tensile strength compared to the as-cast condition. The Brinell hardness of the hot-rolled Cu-10 wt% TiC composite reached 59.54 BHN, representing a 42.1% improvement over as-cast pure copper (41.9 BHN). Similarly, the ultimate tensile strength (UTS) of the hot-rolled Cu-10 wt% TiC composite achieved 182.5 MPa, corresponding to a 50.3% improvement over as-cast pure copper (121.4 MPa). However, ductility decreased progressively with increasing TiC content and hot rolling, from 71.56% in as-cast pure copper to 48.69% in hot-rolled Cu-10 wt% TiC, owing to strain hardening effects and grain boundary restriction by TiC particles. The optimal combined strength-ductility balance, assessed through the strain hardening parameter (UTS % elongation), was achieved at 5 wt% TiC reinforcement in both as-cast and hot-rolled conditions. Fractographic analysis revealed a progressive transition from ductile dimple fracture to mixed-mode and predominantly brittle fracture with increasing TiC content, consistent with the observed mechanical trends. 2026 The Authors. -

GST and its Impact on Small and Medium Scale Enterprises - A Study of Peenya Industrial Area in Banglaore, Karnataka
The introduction of Goods and Service Tax on 1st July, 2017 has revamped the tax structure and carved out a new path for the Indian economy. The new tax regime was envisioned to be free of all the problems of the previous tax system but, however since its proposal it has received mixed reviews from industries, academia and others. With extensive changes aimed at One Nation One Tax, it has left massive impact on the Small Scale Industries too. Hence this paper critically analyses the impact of Goods and Service Tax (GST) on Small Scale Industries specifically in Karnataka. Existing literature says that GST shall reduce the cost of doing business, increases transparency, decreases prices of product, increase tax compliance and improve ease of doing business. This paper proves some of these assertions through a primary data research and further identifies the need of reforms with respect to separation of definition of job work and labour work, penalties for non-payment of GST, dual administration and issues pending from the previous tax regime. It has also clearly established that composition scheme has been a non-performer and the reverse charge mechanism must be re-introduced later or revamped to balance its costs and benefits. Thus the study has implications for policy makers, industries and academia and also provides a better understanding of the new tax system itself. 2021 Lichchavi Harishekar et al., published by Sciendo 2021.
