Ayurveda and another ancient medicine system like traditional Chinese medicine (TCM) and traditional Korean medicine have thousand years of experience in wrist pulse analysis to diagnose the subject's health condition and the root cause of a disease. According to ancient literature, a human’s health status is dependent on three essential constitutions Vata, Pitta, and Kapha (Cun, Guan, and Chi in TCM). The term “tri-dosha” is used to characterize them. An imbalance of these doshas causes disease. Therefore, in modern health practices, it is necessary to understand these pulses imbalance with modern signal processing techniques. In this review, an attempt has been made to discuss the classical hypotheses of pulse measurement based on different Ayurvedic parameters and modern wrist pulse parameters like pulse wave analysis using pulse wave velocity and pulse rate variability. The various modern parameters and other feature extraction methods used to detect multiple diseases are also discussed.</p></div>","PeriodicalId":744,"journal":{"name":"Proceedings of the National Academy of Sciences, India Section A: Physical Sciences","volume":"93 1","pages":"135 - 145"},"PeriodicalIF":0.9,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4809721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The bulk sediments contain up to 28.5% of heavy minerals with an average of 12.5%. Within the heavy minerals, more than 50% are opaque in nature represented by titanomagnetite, magnetite and ilmenite. SEM–EDX studies on handpicked opaque grains indicated a higher concentration of vanadium up to 1.1%. The result of EDX studies was confirmed by AAS analysis of magnetic heavy mineral fraction that showed a concentration of vanadium up to 0.36%. Subsequently, XRD analysis of the heavy minerals of randomly selected samples revealed the presence of vanadium-bearing titanomagnetite as well as the vanadium mineral phase, melanovanadate. EPMA studies carried out in titanomagnetite grains that revealed V<sub>2</sub>O<sub>3</sub> content of 0.36–1.7% with an average of 1.3%.

The transformation relations of a quaternionic variables are established with the help of basis-transformations of quaternion algebra. We deduce the quaternionic covariant derivative that explains how the quaternion components vary with scalar and vector fields. The quaternionic metric tensor and the geodesic equation are also discussed to describe the quaternionic line element in curved space-time. We examine a quaternionic metric tensor equation for the Riemannian Christoffel curvature tensor. We present the quaternionic Einstein’s field-like equation, which indicates that quaternionic matter and geometry are equivalent. <i>Relevance of the work:</i>In recent decades, hypercomplex algebra, viz., quaternion and octonions, has been widely used to explain various branches of physics. In this way, we have investigated quaternionic transformations and field equations in curved space-time. The present novel work will help to explain the characteristics of the curved space-time universe in terms of quaternion algebra.

Accurate position information of medical staffs and patients is required for data transmission, tracking, navigation, etc. Seamless data transmission while user is on the move has been conceptualized considering the optical network formed by photosensor (light emitting diode)-based transmitters. Efficiency of these services depends on the position accuracy. To investigate factors contributing to higher position errors in a practical environment, the proposed system is evaluated. Evaluation is done through simulation and experiment for different channel conditions, and the receiver rotation due to user mobility. Simulation results show an average two-dimensional position error of 0.32 m in a channel with a strong background light illumination level of − 60 dBm. Experimental results show that the mean position error is 0.7 m in a normal daytime indoor light condition.</p></div>","PeriodicalId":744,"journal":{"name":"Proceedings of the National Academy of Sciences, India Section A: Physical Sciences","volume":"93 1","pages":"121 - 133"},"PeriodicalIF":0.9,"publicationDate":"2022-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40010-022-00792-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4935398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
