 Abstract

This research presents a real-time driver drowsiness detection and alert system using Python-based computer vision and machine learning techniques. The system combines several detection methods--including Eye Aspect Ratio (EAR), facial landmark tracking, head pose estimation, and temporal behavioral analysis--to accurately identify signs of fatigue. Using OpenCV, dlib's 68-point landmark model, and scipy for signal analysis, it provides multi-modal alerts through audio, visual, and haptic feedback. Tested on 150 participants under varied lighting, demographics, and driving conditions, the system achieved 96.7% accuracy, 94.3% sensitivity, 97.8% specificity, and a rapid 0.98-second response time. It also maintains real-time performance at 35 FPS and reduces false positives to 2.1%, outperforming existing commercial solutions. Additional features include adaptive user calibration, environmental condition adjustments, and APIs for seamless integration into vehicle systems. Overall, the system demonstrates strong reliability and suitability for widespread use in advanced driver assistance systems (ADAS).

 Abstract

Cryptocurrency has emerged as a revolutionary form of digital currency, challenging traditional financial systems and legal frameworks across the world. Its decentralized nature, anonymity in transactions, and borderless functioning raise significant legal implications that demand critical examination. In India, the status of cryptocurrency remains uncertain due to the absence of specific legislation and the fluctuating judicial and regulatory approach. While the Supreme Court in Internet and Mobile Association of India v. Reserve Bank of India (2020) struck down the RBI's banking ban on virtual currencies, the lack of comprehensive regulatory guidelines continues to pose challenges. The legal implications primarily revolve around issues of taxation, money laundering, investor protection, cybersecurity, and the possible conflict with existing financial laws. Moreover, the potential misuse of cryptocurrency in terror financing and illegal trade further complicates the regulatory landscape. This paper seeks to analyze the evolving legal status of cryptocurrency in India, compare it with international frameworks, and suggest reforms that balance innovation with legal certainty and consumer protection.

 Abstract

Sepsis, a life-threatening organ dysfunction due to a dysregulated host response to infection, continues to pose a significant clinical challenge despite advances in supportive care. The review synthesizes findings from randomized controlled trials and cohort studies to evaluate the impact of vitamin C--administered alone or in combination with thiamine and hydrocortisone--on key outcomes such as mortality, organ dysfunction (SOFA scores), vasopressor requirements, and safety profiles. The evidence regarding vitamin C monotherapy is mixed: several meta-analyses suggest possible reductions in mortality and improvements in SOFA scores and vasopressor duration, but these findings are not consistently statistically significant, and some large trials even indicate potential harm. Combination therapies, particularly the "metabolic resuscitation cocktail" (vitamin C, thiamine, hydrocortisone), have not demonstrated significant mortality benefit in high-quality trials, though modest improvements in organ dysfunction metrics are observed. Vitamin C is generally well tolerated, but rare adverse effects--such as increased renal replacement therapy or hypernatremia--have been reported in certain studies, warranting caution in patients with specific comorbidities. Substantial heterogeneity in dosing regimens, timing, patient populations, and study design complicates interpretation, and the overall certainty of evidence for major outcomes remains low to moderate according to GRADE criteria. Current guidelines do not recommend routine intravenous vitamin C use in sepsis outside of clinical trials. The review underscores the need for large, well-designed randomized studies to identify patient subgroups most likely to benefit, determine optimal dosing strategies, and clarify the role of vitamin C--alone or in combination--in improving clinically significant outcomes in sepsis. This systematic literature review critically examines the efficacy and safety of intravenous vitamin C administration in the management of sepsis and septic shock.

 Abstract

The scam of 1992 by Harshad Mehta remains one of the most infamous financial scandals in India's history, exposing deep-rooted flaws in the country's financial and legal regulatory systems during the 90's era. This Incident was marked as the biggest setback in Indian financial governance and market transparency in which Harshad Mehta, a prominent stockbroker, orchestrated a sophisticated scheme to manipulate stock prices and misappropriate funds from banks by exploiting gaps in the banking and security markets ecosystem resulting in the occurrence of an white collar crime which involved the embezzlement of Rs 1439 crore [$3 billion], leading to an profound financial crisis and the heartbreaking loss of life savings and assets for countless investors, with the total economic fallout reaching to Rs 3542 crore [approximately $7 billion]. This paper takes an in-depth dive into the legal intricacies of the 1992 scam, analyzing how the fraud was executed, the evidence presented, and the judicial response that followed. It also analyses the gaps in financial investment laws of that time and the regulatory loopholes that Mehta exploited, leading to much-needed urgent reforms in India's financial and legal framework by bringing robust legal safeguards and more stringent regulatory oversight to preserve market integrity, steering India towards a more transparent and accountable economic and financial system.

 Abstract

When Hepatitis-B is diagnosed, the quest for a reliable curative treatment in any medical system starts. Which physician should I see? Which doctor specializes in treating Hepatitis B or C infections, or the gastroenterologist with the largest list of alphabets after his name? How is the doctor chosen? Excellent question as well. You should see a physician with extensive clinical experience in treating infections caused by Hepatitis B or C. Instead of choosing someone with book knowledge of Hepatitis B or C, look for a physician with a long history of treating Hepatitis B and C cases alone. Practice is only focused on clinical abilities and knowledge, whereas study allows one to earn more degrees. Hepatitis B virus (HBV) remains a major global health challenge, affecting millions of individuals and contributing significantly to chronic liver disease, cirrhosis, and hepatocellular carcinoma. This comprehensive review summarizes current knowledge on HBV epidemiology, virology, modes of transmission, clinical manifestations, and diagnostic approaches. It highlights recent advances in understanding the viral life cycle, host immune responses, and mechanisms of persistence that complicate therapeutic eradication. Current prevention strategies--including universal vaccination, maternal screening, and antiviral prophylaxis--are discussed alongside available antiviral therapies that suppress viral replication and reduce long-term complications. Despite substantial progress, HBV cure remains elusive due to the stability of covalently closed circular DNA (ccc DNA) and viral integration into host genomes.

 Abstract

Modern technological advancements have accelerated the development of miniaturized and portable analytical devices, enabling on-site, real-time, and decentralized chemical analysis. Traditional laboratory instruments, although highly accurate and sensitive, are often bulky, expensive, and require skilled personnel. Portable analytical devices overcome these limitations through miniaturization of components, integration of microfluidics, smartphone- assisted detection, point-of-care diagnostics, and the use of nanomaterials. These devices allow rapid screening of chemicals in environmental monitoring, food safety, forensic investigations, pharmaceuticals, toxicology, and biomedical diagnostics. The increasing demand for low-cost, fast, and user-friendly analytical solutions has driven innovations in lab-on-a-chip (LOC), paper-based microfluidics, portable spectrometers, electrochemical sensors, and handheld chromatographic systems. This review provides an extensive overview of the types, working principles, fabrication methods, influencing factors, advantages, limitations, and future prospects of miniaturized analytical systems.

 Abstract

The introduction of the Goods and Services Tax (GST) in India represents one of the most significant indirect tax reforms aimed at creating a unified national market and improving tax efficiency. By subsuming multiple central and state-level indirect taxes into a single tax framework, GST sought to eliminate cascading effects, simplify compliance, and enhance transparency in the taxation system. The manufacturing sector, being a major contributor to India's GDP, employment, and exports, occupies a crucial position in assessing the effectiveness of this reform. This paper provides a conceptual and analytical review of the structure and evolution of GST in India, with specific emphasis on its implications for the manufacturing sector. Using secondary data and an extensive review of existing literature, policy documents, and government reports, the study examines the dual GST model, rate structure, input tax credit mechanism, and institutional framework governing GST. The paper also identifies key challenges faced by the manufacturing sector under the GST regime, including rate complexity, compliance burden, working capital pressures, and transitional issues. The study concludes by highlighting the need for continued policy refinement to ensure that GST achieves its intended objectives of efficiency, competitiveness, and sustainable industrial growth.

 Abstract

For medications that are mostly absorbed in the upper gastrointestinal (GI) tract segments the stomach, duodenum, and jejunum floating drug delivery systems (FDDS) offer an extra benefit. The quantitative effectiveness of floating delivery systems in the fed and fasted states, the contribution of buoyancy to improving FDDS's gastro residence time (GRT), and the relationship between extended GRT and sustained release/pharmacokinetic features are some of the important, unresolved issues surrounding the logical development of FDDS. The polymers employed in floating drug delivery formulations and systems have advanced significantly, and they can now accomplish more than just prolong a drug's effective release period. It is detailed how polymeric excipients (Es) are referred to in the technology utilized to create floating drug delivery systems (FDDS). The most popular polymer groups, their characteristics, and their function in different technical techniques to attaining buoyancy have been identified based on the information provided in research articles. Furthermore, methods for altering the API release in these systems are explained, along with the Es that are employed. The present developments in the application of polymers in floating dosage form (FDF) technology are described, together with broad conclusions regarding the future of this field.
