Resistive Random Access Memory: Materials, Filament Mechanism, Performance Parameters and Application

Till today, we are using conventional technologies for memory-related applications. However, as the size of the electronic devices are shrinking day by day, such conventional memory devices will not be compatible with emerging applications like artificial intelligence, cloud storage, data mining, Internet of Things, etc. After the coronavirus outburst, these technologies are more needed as now all work is online. Henceforth, high data storage and fast information processing is one of the vital requirements which is to be researched. So, the researchers are now approaching the new memory technologies such as resistive random access memory (RRAM) which is superior than conventional memory devices in terms of scalability, speed, power consumption, design structure and many more other advantages. With all the pros, RRAM also has some cons like higher level of variability and reliability issues. So, to discuss all these issues, we present the basics of RRAM, their advantages, applications and technological trends in this manuscript. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Mass Gathering and Population Movement in India: Possible Risk of Vector-Borne Diseases

Surveillance tools measure and help to predict the possibility of the onset of any disease including vector-borne diseases during some specific situations likemass gatherings (MGs) that are closely related tothe disease epidemiology (why, what, who, where, when, and how)concerningthe transmission of infectious diseases including vector-borne diseases. Some situations ofmass gatherings may bring closely large and diverse population groups coming from different endemic zones/areas leading tothe transmission of communicable diseases including vector-borne diseases. Mass gatherings (MGs) may have the potential to enhance the transmission dynamics of vector-borne diseasesowing to different geographical, social, and climatic factors. Usually, MGs have been thought to have enhanced risks of disease transmission.Theyalso have the potential to increase the opportunities for other types of mechanical injuriesfrom accidents, stampedes, alcohol use, internal group fights etc. that may result in morbidity or mortality.Besides, they are potential breeding places for the proliferation of vector species, capable of transmitting malaria, dengue, chikungunya, and JE including ticks and mites-borne diseases. It is a well-known fact there area large number of asymptomatic cases which act as sub-clinical cases, hence, chances of local transmission through vectors during such mass gatherings can not be ruled out.There is always a need for well-structured, intensified real-time disease and vector surveillance and reporting systems in place which is essential for efficient MG planning, to ensure disease prevention and control. In the present context of the ongoing COVIDpandemic, such surveillance systems havebecome a vital component of such events of mass gatherings and large-scale movement of people. © 2022: Author(s).

The role of herbal immunomodulators as adjuvant therapy for asymptomatic and mildly symptomatic covid-19: An exploratory clinical study

Objectives: The objective of the study is to evaluate herbal immunomodulators (Septilin and Bresol) as a possible adjuvant therapy for the treatment of asymptomatic and mildly symptomatic COVID-19. Methods: Randomized, open-label, comparative clinical study. Subjects were randomized to either arm I [Septilin and Bresol+standard of care (SOC)] or arm II (SOC). This study was registered on CTRI (CTRI/2020/06/025801). Results: Subjects in arm I showed a greater reduction in levels of interleukin-6 tumor necrosis factor-α following treatment than in arm II. Subjects in arm I showed a greater increase in levels of interferon (IFN)-β and IFN-λ than those in arm II. There was a greater reduction in D-dimer in arm I than in arm II subjects (64.28% vs. 35.59%) and all arm I subjects had D-dimer values in the normal range compared to 70% of arm II subjects. There were statistically significant reduction in lactate dehydrogenase and neutrophil-to-lymphocyte ratio in arm I (p<0.016 and p<0.013, respectively). Clinical assessments during the post-illness convalescence period showed significant improvements in fatigue assessment scores and quality of life. Conclusion: This herbal combination as an adjuvant to SOC may provide additional long-term benefits in COVID-19 infection by reducing inflammation. This treatment may offer a good addendum for the management of post-COVID-19 illness.

Real-Time Face Mask Detection Using Raspberry Pi and Camera

We all know that this is the ERA of Coronavirus diseases (COVID-19). It is a kind of pandemic which is growing at a fast rate and causing a health crisis. It caused many deaths last years and still counting. So, the doctors and scientists are working on the vaccine for this virus and also, they have suggested some ways to be safe from this virus, face masks are one of the most common measures to fight such virus. In this paper, we have discussed on the project about face mask detection using Raspberry Pi and a live video streaming camera. The face mask detection model was done with the help of a computer vision, CNN, image classification algorithm based on the MobileNetV2 neural network. The steps involved in the project are: firstly, we have taken the data-set of people wearing the face mask and then those not wearing the face mask, after then we pre-processed it, split the data, trained the model using MobileNetV2 neural network, tested the model, and finally implemented the model. The model has been trained with an accuracy of 95.85%. This system automatically opens the door when people are wearing the face mask and sends an alert if they don’t have the face mask, to the authorities or the owner of the place. It can be used in a variety of places, include educational institutions, hospitals, churches, and retail outlets. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

A randomized control study to evaluate the role of herbal immunomodulators in boosting the immunity and overall health of healthcare workers in COVID-19 wards: An exploratory, feedback clinical study

Objective: The objective of the study was to evaluate the role of the herbal immunomodulators Immusante and Guduchi in boosting the immunity and overall health of healthcare workers assigned to coronavirus disease 2019 (COVID-19) wards. Methods: An open-label, randomized, prospective, and single center clinical study was conducted among 100 healthcare workers assigned to COVID-19 wards. Eligible subjects (50 in each arm) were randomly assigned to either arm I (Immusante+Guduchi tablets) or arm II (treatment as per the institutional policy). Assessments after 30 days of treatment included respiratory symptoms, Adapted Immune Status Questionnaire (ISQ), improvement in quality of life (Short form 12 [SF-12] Health Survey), and safety and tolerability. Results: All 100 subjects completed the study as per the protocol. There were no respiratory symptoms in the subjects in arm 1. However, four subjects (8%) in arm II reported cough during the study period. A better Immune status improvement was seen through the adapted ISQ in arm I as compared to arm II. In each of the 8 SF-12 Health Survey domains, a statistically significant difference was observed in arm I compared to arm II. A retrospective assessment of COVID-19 infection showed only 8% of subjects as COVID-19 positive in arm I compared with 26% of subjects in arm II. Conclusion: Considering the positive trend observed in this study in terms of ISQ, SF-12, and COVID-19 infection rates, the combination of Immusante and Guduchi in healthcare workers at a high risk of contracting COVID-19 infection had a beneficial effect in boosting immunity and overall health.

Forensic dna examination in the pandemic era of covid-19: An indian perspective

The extremely high nature of transmissibility and severity of infection due to the novel Corona virus is a serious threat to mankind. This letter delivers a cau-tion for forensic DNA experts in the era of COVID-19 infection from the Indian perspective. Samples are routinely transported to laboratories without any spe-cific guidelines. Therefore, this is high time to formu-late clear guidelines for the handling of biological ma-terial, from receiving to processing in the laboratory during such a pandemic. © 2021. AJFSFM.
