A secured and optimized deep recurrent neural network (DRNN) scheme for remote health monitoring system with edge computing
Patients now want a contemporary, advanced healthcare system that is faster and more individualized and that can keep up with their changing needs. An edge computing environment, in conjunction with 5G speeds and contemporary computing techniques, is the solution for the latency and energy efficiency criteria to be satisfied for a real-time collection and analysis of health data. The feature of optimum computing approaches, including encryption, authentication, and classification that are employed on the devices deployed in an edge-computing architecture, has been ignored by previous healthcare systems, which have concentrated on novel fog architecture and sensor kinds. To avoid this problem in this paper, an Optimized Deep Recurrent Neural Network (O-DRNN) model is used with a multitier secured architecture. Initially, the data obtained from the patient are sent to the healthcare server in edge computing and the processed data are stored in the cloud using the Elliptic Curve Key Agreement Scheme (ECKAS) security model. The data is pre-processed and optimal features are selected using the Particle Swarm Optimization (PSO) algorithm. O-DRNN algorithm hyper-parameters are optimized using Bayesian optimization for better diagnosis. The proposed work offers superior outcomes in terms of accuracy and encryption latency while using computational cloud services
A study of transition spaces in traditional houses of Tamil Nadu
Architecture is inevitably a mechanism for social purposes that could impact the personal and public levels. While architecture is used in many different ways, the arrangement and structure of places are fundamental and essential to people's lives. Thus, the people started to create spaces allowing them to eat, sleep, worship, learn, argue, recreate, and so on in a specific timeframe that has been subjected to the tradition and culture of people. This study is about one such traditional transition space - the thinnai that creates connectivity between the public and private zones in a housing typology. As evolution occurs, these structures, intended for various activities, have vanished, and compound wall structures have enclosed the dwellings. This shortens the connectivity to the external environment. In southern India, the thinnai spaces serve various socio-cultural activities. The typology of the thinnai spaces differs according to the regions of settlement, occupation and religious practices. Such spaces have been recreated due to the refurbishment of the buildings, which will not require them to serve their purpose. The main objective of the paper is to document and analyze the transitional spaces (known as thinnai or raised platform) prevailing near the entrance in the varied typology of traditional houses in a village in Tamil Nadu and to classify them based on the thresholds. The qualitative study was carried out through intense documentation analysis of transition spaces near thresholds in the varied typology of traditional houses in Mangalrevu village Tamil Nadu. The result of the study showed that the transitional spaces that exist near thresholds in traditional buildings have demonstrated extensive functionality and lie in harmony with the people's lifestyle. Further, the authors also classified the types of transition spaces with respect to the thresholds. It is considered the need of the hour to replicate these structures with the same meaning in modern dwellings without any compromises
Climate responsive design principles in Dravidian temples: A case study of Nellaiyappar temple
298-305The main objective of this paper is to focus on climate responsive design strategies adopted in one of the Dravidian temples, the Nellaiyappar temple, Tirunelveli, as a case example. Temples were the main gathering space and also a source of recreation in the olden days. The temple complexes are spaces with cultural vibrancy. The areas in and around the temple complexes are designed with consideration of the local climatic factors. Each space is designed per the activity, rituals held, and the climatic considerations of that region. In pursuing the investigation, the paper focuses on two main objectives. The first part of the study was to analyse the evolution of Dravidian temples with ages and its space planning within the temple complex. The planning of the temple complex and the materials used in the construction have crossed several transitions, starting from the rock-cut temples to structural temples. The evolution happened across various dynasties, from the Pallava dynasty to Nayaks. The second part of the study was to investigate the influence of climatic factors of the place on the planning of the temple and its precincts. Directly or indirectly, the climatic condition of the site controls the planning features and materials used in construction. Literature analyses of both objectives were done, and to examine them, Nellaiyappar temple, Tirunelveli, was taken as a case example. The study was done using a single method analysis that includes qualitative analysis. This qualitative study was done by a live case study visit to the temples, and further investigation was conducted by reading the plans, photographs, sketches, and sections. The entire temple complex was analysed qualitatively and found that responsive climate strategies were evident in the Nellaiyappar temple, and the design ideas may be adopted in modern temple typologies

Effects of built environment on healing the mental health of the people–literature review
Purpose – The coronavirus disease 2019 (COVID-19) pandemic has been reported to have a major impact on the mental health of an individual. Healing the mental stress, anxiety, depression and insomnia of an individual's immediate surroundings play a major role. Therefore, this study reviews how the built environment impacts the healing of an individual's state of mind. Design/methodology/approach – Various works of literature on healing environments were analysed to create frameworks that can facilitate psychological healing through architectural elements. Articles were selected from various journals like SAGE, PubMed, Journal of Applied and Computational Mechanics (JACM), Routledge Taylor and Francis, Journal of Contemporary Urban Affairs (JCUA), ScienceDirect, and Emerald databases, news articles, official web pages, and magazines that have been referred. Findings – Indicators (spatial, sensory comfort, safety, security, privacy and social comfort) are linked to sub-indicators (access, distractions and views) and design characteristics (indoor climate, interior view, outside view, privacy, communication, noise, daylighting, temperature) which help in better connection of the built environment with individual's mental health. From the above indicators, sub-indicators and design characteristics, the authors have come to a conclusion that a view to the outside with better social interaction has an in-depth effect on an individual's mental health. Research limitations/implications – This study predominantly talks about healing in hospitals but quarantining of COVID-19 patients happens in residences too. So, it is important to find the healing characteristics in residences and in which typology the recovery process is high.

Purpose – This literature review paper aims to discuss the impacts and measures taken on Covid-19 with respect to architecture, built form and its allied fields along with observations from around the world with the end results of its implementation. Design/methodology/approach – Various research journals from Science Direct and Taylor and Francis among others were referred and reviewed to learn more on Covid-19 along with its impacts on people and their built environment. Keywords that aligned with the topic of interest like pandemic, Covid-19, coronavirus, urban spaces, built environment and built-up space were identified. Research papers that aligned with the scope of the paper and its keywords were found. An excel sheet with the basic data of these papers was written down. The essence of each of these articles were understood and linked with the topic in hand. A review of all these papers was written coherently to the topic. Future scope in this field of study was also identified. Findings – It discusses the various measures taken around the world in built-up spaces along with the various measures given by researchers, architects and urban planners to mitigate and reduce the transmission of Covid-19 in the built environment and urban spaces. The discussed measures along with observations from around the world have also been discussed with its end results. Discussions and conclusions on these design strategies and recommendations are made with the anticipation of a paradigm shift due to post-pandemic changes. Current scenarios of public spaces in densely populated countries are discussed. Future scope in this ongoing field of study includes measures that can be taken in specific to some particular built-up typologies like markets, theaters, parks, bazaars, etc. Research limitations/implications – The limitation of this study is the restricting of the study of Covid-19 to only architectural, urban and public realm scales. The study does not facilitate the involvement of other fields and their influence with Covid-19. Originality/value – This paper has been completely written by the author and the co-authors and has not been copied from any other sources
SENSOR APPLICATIONS IN ANALYSIS OF DRUGS AND FORMULATIONS
Several sensors, biosensors, and actuators are designed and mounted to analyze biomedical nutraceuticals, food, and nutraceutical products in this particular issue. Some applications concern classical subjects such as eubacteria determination in agricultural products, flashing material in foods such as the ethyl group’s chemicals, and fruit juices’ inhibitor properties. In contrast, the different applications are more revolutionary, such as safety research, the manufacture of artificial human senses (electronic nose or tongue), or t Ligands are often characterized by nano biosensors, utilizing biomaterials that involve specific aptamers, antibodies, enzymes, polymers, and sensory receptors. The square measurement of several modal sensing elements, integrated with nanomaterials, increases sensitivity such as nano biosensors and increases nano biosensor productivity. For the nano biosensor with increased efficiency, modality sensing components have been incorporated in this case. The square measurement of the elastic (ME) magnetic machine biosensors was used to classify infectious agents by a magnet coil in contemporary juice or milk and to develop direct detection of infectious agents on food scanning coils
Electronic structure of NiS_{1-x}Se_x
We investigate the electronic structure of the metallic NiSSe
system using various electron spectroscopic techniques. The band structure
results do not describe the details of the spectral features in the
experimental spectrum, even for this paramagnetic metallic phase. However, a
parameterized many-body multi-band model is found to be successful in
describing the Ni~2 core level and valence band, within the same model. The
asymmetric line shape as well as the weak intensity feature in the Ni~2 core
level spectrum has been ascribed to extrinsic loss processes in the system. The
presence of satellite features in the valence band spectrum shows the existence
of the lower Hubbard band, deep inside the metallic regime, consistent
with the predictions of the dynamical mean field theory.Comment: To be published in Physical Review B, 18 pages and 5 figure
Estimates of electronic interaction parameters for LaO compounds (=Ti-Ni) from ab-initio approaches
We have analyzed the ab-initio local density approximation band structure
calculations for the family of perovskite oxides, LaO with =Ti-Ni
within a parametrized nearest neighbor tight-binding model and extracted
various interaction strengths. We study the systematics in these interaction
parameters across the transition metal series and discuss the relevance of
these in a many-body description of these oxides. The results obtained here
compare well with estimates of these parameters obtained via analysis of
electron spectroscopic results in conjunction with the Anderson impurity model.
The dependence of the hopping interaction strength, t, is found to be
approximately .Comment: 18 pages; 1 tex file+9 postscript files (appeared in Phys Rev B Oct

Performance and Stability of Pearl Millet Varieties for Grain Yield and Micronutrients in Arid and Semi-Arid Regions of India
Pearl millet [Pennisetum glaucum (L.) R. Br.] is grown under both arid and semi-arid
conditions in India, where other cereals are hard to grow. Pearl millet cultivars, hybrids,
and OPVs (open pollinated varieties) are tested and released by the All India Coordinated
Research Project on Pearl Millet (AICRP-PM) across three zones (A1, A, and B) that are
classified based on rainfall pattern. Except in locations with extreme weather conditions,
hybrids dominate pearl millet growing areas, which can be attributed to hybrid vigor and
the active role of the private sector. The importance of OPVs cannot be ruled out, owing
to wider adaptation, lower input cost, and timely seed availability to subsidiary farmers
cultivating this crop. This study was conducted to scrutinize the presently used test
locations for evaluation of pearl millet OPVs across India, identify the best OPVs across
locations, and determine the variation in grain Fe and Zn contents across locations in
these regions. Six varieties were evaluated across 20 locations in A1 and A (pooled as
A) and B zones along with three common checks and additional three zonal adapted
checks in the respective zones during the 2019 rainy season. Recorded data on yield and
quality traits were analyzed using genotype main effects and genotype × environment interaction biplot method. The genotype × environment (G × E) interaction was found to
be highly significant for all the grain yield and agronomic traits and for both micronutrients
(iron and zinc). However, genotypic effect (G) was four (productive tillers) to 49 (grain
Fe content) times that of G × E interaction effect for various traits across zones that
show the flexibility of OPVs. Ananthapuramu is the ideal test site for selecting pearl millet
cultivars effectively for adaptation across India, while Ananthapuramu, Perumallapalle,
and Gurugram can also be used as initial testing locations. OPVs MP 599 and MP
600 are identified as ideal genotypes, because they showed higher grain and fodder
yields and stability compared with other cultivars. Iron and zinc concentration showed
highly significant positive correlation (across environment = 0.83; p < 0.01), indicating
possibility of simultaneous effective selection for both traits. Three common checks were
found to be significantly low yielders than the test entries or zonal checks in individual
zones and across India, indicating the potential of genetic improvement through OPVs
