EFFECT OF ELECTRIC FIELD, TEMPERATURE AND CORE DIMENSIONS IN III – V COMPOUND CORE – SHELL NANOWIRES
ASHWANI VERMA,Bahniman Ghosh,AKSHAY KUMAR SALIMATH 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2014 NANO Vol.9 No.4
In this paper, we have used semiclassical Monte Carlo method to show the dependence of spinrelaxation length in III – V compound semiconductor core – shell nanowires on di®erent parameterssuch as lateral electric ¯eld, temperature and core dimensions. We have reported the simulationresults for electric ¯eld in the range of 0.5 – 10 kV/cm, temperature in the range of 77 – 300 K andcore length ranging from 2 nm to 8 nm. The spin relaxation mechanisms used in III – V compoundsemiconductor core – shell nanowire are D'yakonov – Perel (DP) relaxation and Elliott – Yafet (EY)relaxation. Depending upon the choice of materials for core and shell, nanowire forms two types ofband structures. We have used InSb – GaSb core – shell nanowire and InSb – GaAs core – shellnanowire and nanowire formed by swapping the core and shell materials to show all the results.

Ashwani Kumar,Anshu Chaudhary,Chandni Verma,Hridaya Shanker Singh 대한기생충학열대의학회 2014 The Korean Journal of Parasitology Vol.52 No.6
The rumen parasite, Gastrothylax crumenifer (Platyhelminthes: Gastrothylacidae), is a highly pathogenic trematode parasite of goat (Capra hircus). It sucks blood that causes acute disease like anemia, and severe economic losses occur due to morbidity and mortality of the ruminant infected by these worms. The study of these rumen paramphistomes, their infection, and public health importance remains unclear in India especially in the western part of state Uttar Pradesh (U.P.), Meerut, India, where the goat meat consumption is very high. This paper provides the molecular characterization of G. crumenifer recovered from the rumen of Capra hircus from Meerut, U.P., India by the partial sequence of 28S rDNA. Nucleotide sequence similarity searching on BLAST of 28S rDNA from parasites showed the highest identity with those of G. crumenifer from the same host Capra hircus. This is the first report of molecular identification of G. crumenifer from this part of India.

India’s efforts to achieve 1.5 billion COVID-19 vaccinations: a narrative review
Kapil Singh,Ashwani Verma,Monisha Lakshminarayan 질병관리본부 2022 Osong Public Health and Research Persptectives Vol.13 No.5
The initial case of coronavirus disease 2019 (COVID-19) in India was reported on January 30, 2020, and subsequently, the number of COVID-19-infected patients surged during the first wave of April 2020 and the second wave in the same month of 2021. The government of India imposed a strict nationwide lockdown in April 2020 and extended it until May 2020. The second wave of COVID-19 in India overwhelmed the country’s health facilities and exhausted its medical and paramedical workforce. This narrative review was conducted with the aim of summarizing the evidence drawn from policy documents of governmental and non-governmental organizations, as well as capturing India's COVID-19 vaccination efforts. The findings from this review cover the Indian government's vaccination initiatives, which ranged from steps taken to combat vaccine hesitancy to vaccination roadmaps, deployment plans, the use of digital health technology, vaccination monitoring, adverse effects, and innovative strategies such as Har Ghar Dastak and Jan Bhagidari Andolan (people’s participation). These efforts collectively culminated in the successful administration of more than 1.8 billion doses of COVID-19 vaccines in India. This review also provides insights into other countries’ responses to COVID-19 and guidance for future pandemics.
