COMPREHENSIVE REVIEW OF MICROSTRIP FILTERS FOR GLUCOSE AND TENSION SENSING APPLICATIONS

Authors:

Shahad K. Khaleel

Abstract:

This review paper provides a rigorous and comprehensive analysis and sets up a unified electromagnetic (EM) framework for planar microstrip resonant filters for two seemingly different but electromagnetically similar applications: non-invasive blood glucose monitoring and structural tension sensing. This work connects biochemical and mechanical tracking, studying the convergence of high-frequency planar technologies and complex material media. Four important microwave resonator topologies are analysed in detail, including Split Ring Resonators (SRR), Complementary Split Ring Resonators (CSRR), Hairpin Resonators, and Stub-Loaded Resonators (SLR). The underlying transduction physics is rigorously formulated, using the 3D vector cavity perturbation theory and conformal mapping expressions, coupled with modified first-order Cole-Cole dielectric relaxation equations. Mechanical strain deformation is explicitly linked to matrices of transmission lines to map physical elongation, Poisson’s ratio, and substrate elastomeric variations directly to resonance perturbations. Performance benchmarks are synthesized through a quantitative meta-analysis of literature covering the last five years, highlighting the basic trade-offs among near-field localization, quality factor (QL), and linear correlation coefficient (R2). In addition, we tackle some of the key engineering challenges, including the high loss tangent of human tissue, water absorption damping between 2-10 GHz, and thermal-mechanical drift cross-sensitivity. A multi-parameter calibration matrix framework, based on an isolated reference resonance peak, is described to overcome these multi-parameter interferences. Lastly, we discuss future directions for edge-computed machine learning calibration engines and passive, battery-free, chipless telemetry radio frequency identification (RFID) sensor tags for remote deployment.

Abstract:

Background: Breast cancer is the most common form of cancer among women in India. Early detection plays a vital role in reducing mortality rates and improving the quality of life. Breast self-examination (BSE) is an easy and economical method for detecting any abnormalities. Nursing students play an important role as future healthcare professionals in educating people about breast cancer.

Objectives: This study was conducted to measure the knowledge and practices of BSE among the first year B.Sc. Nursing students and to establish the relationship between the two variables.

Methods: A descriptive cross-sectional study was conducted among 80 first year B.Sc. Nursing students studying at SCB College of Nursing, Cuttack. Convenience sampling technique was used for data collection. Structured questionnaire and checklist were used for data collection. Inferential and descriptive statistics were used for analysis.

Results: Findings revealed that 52.5% of the participants had insufficient knowledge about BSE and 68.75% had never performed BSE regularly. There exists a positive correlation (r= 0.42) between the scores on knowledge and practices.

Conclusion: There was a wide knowledge-practice gap found among nursing students. Recommendations include conducting workshops and practical sessions for the students.

Discrete Fasting in Weight Loss: Metabolic Mechanisms, Clinical Outcomes, and Future Perspectives

Authors:

Ank Gabor

DOI:

Abstract:

One of the most effective dietary strategies for weight loss and improving metabolic health is known as Discrete Fasting or Intermittent Fasting (IF). Discrete fasting is different from traditional diets of continuous calorie reduction, which alternate periods of fasting with feeding, thereby promoting metabolic adaptation towards improved fat oxidation and ketone utilization. Although the beneficial effects of fasting-based treatments on body composition, insulin sensitivity, lipid metabolism and cardiovascular markers have been shown in recent clinical trials, the mechanism behind these remains unclear. The present paper includes a detailed analytical discussion on the physiological, metabolic and clinical implications of discrete fasting in weight management. A simulated comparative study is included with the paper that focuses on continuous calorie restriction, time-restricted eating and alternate day fasting. Several tables and valid graphical figures are used to illustrate the changes in body weight, body mass index, blood glucose level, body fat percentage and lipid profiles. The results show that the alternate day fast and time-restricted eating result in better metabolism than traditional calorie restricting strategies. In addition, the paper describes the mechanisms of fasting, such as ketosis, hormonal adaptations, depletion of glycogen, and autophagy. The possibilities for future applications such as AI, wearable health systems, bespoke fasting plans and digital nutrition monitoring are also discussed. The study findings indicate that discrete fasting is an effective and viable method of obesity control and metabolic optimization.

The Evolution and Architecture of Agentic Open Source Intelligence

Authors:

Arunanshu Chatterjee, Anurag Roy

DOI:

Abstract:

This comprehensive review paper examines the ontological shift in Open Source Intelligence (OSINT). For decades, the field was strictly defined by the extraction of actionable intelligence from publicly accessible data, operating on a linear, highly manual pipeline that relied entirely on human cognitive processing. The advent of Agentic Artificial Intelligence (AI) fundamentally displaces this foundational paradigm. By transitioning the discipline from reactive data aggregation to proactive, autonomous execution, agentic architectures redefine the intelligence lifecycle, shifting the cognitive burden of data processing, correlation, and initial synthesis from human operators to autonomous algorithmic systems. To clarify the academic boundaries and methodological intent of this document, it must be explicitly stated that this is a comprehensive review paper rather than a presentation of singular novel empirical research. The objective of this review is to systematically aggregate, synthesize, and critically evaluate the theoretical, mathematical, and architectural state-of-the-art across the rapidly expanding domain of Agentic AI in cybersecurity and OSINT. By analyzing recent academic frameworks published across leading repositories—such as the Institute of Electrical and Electronics Engineers (IEEE), the Association for Computing Machinery (ACM), Springer, and Elsevier—this paper provides a definitive structural analysis of the current landscape. This review specifically addresses the mathematical foundations of autonomous reasoning through Bayesian probabilistic updating, constructs structural models of multi-agent collaborative topologies, evaluates the operational efficacy of specialized cybersecurity frameworks, and thoroughly examines the profound socio-technical friction generated by this paradigm shift, specifically focusing on the barrier of algorithmic trust, legal accountability deficits, and the emerging defensive imperative to track Non-Human Identities (NHIs).

Abstract:

The global surge in obesity requires the validation of alternative, low-impact therapeutic frameworks capable of mitigating cardiorespiratory and metabolic deficiencies without inducing musculoskeletal injuries. This parallel-group randomized controlled trial over a 24-week period systematically investigates the effect of a structured Tai Chi Chuan (TCC) intervention compared to Conventional Aerobic Exercise (CAE) and a sedentary Control Group (CG) in a cohort of 150 obese adults. Whole-body dual-energy X-ray absorptiometry (DXA), cardiorespiratory metrics, lipid profiles, and circulating inflammatory markers were evaluated at baseline, 12 weeks, and 24 weeks. Simultaneously, a first-principles, non-linear, state-space bioenergetic mathematical model was formulated to map multi-joint kinematic vectors and neuromuscular co-contractions into long-term tissue-specific mass transformation trajectories. Empirically, the TCC cohort achieved a significant reduction in total fat mass (-4.26 kg) and a 12.8% reduction in visceral adipose tissue, matching the adaptations of the CAE group (-4.41 kg fat mass; 13.1% visceral adipose tissue loss). Crucially, TCC demonstrated preservation of lower-limb lean mass (+0.38 kg) and achieved an adherence rate of 94% due to reduced joint pain. Circulating hs-CRP and HOMA-IR decreased significantly by 22.4% and 26.4%, respectively, within the TCC cohort. The mathematical modeling system tracked actual mass changes with an R² accuracy of 0.942 for fat mass trajectory mapping. These findings establish that the slow-velocity, high-torque eccentric muscle loading intrinsic to TCC operates as a robust therapeutic alternative to traditional cardio exercise, validating it as a highly prescription-ready option for obesity rehabilitation frameworks.
