Priyanshi Gupta,Sanjay Sehgal 세종대학교 경제통합연구소 2019 Journal of Economic Integration Vol.34 No.4
We study time-varying interest rate comovement and its determinants for the retail banking sector in the euro area over pre-crisis and during crisis, between 2003 and 2018. The analysis is conducted for 11 euro area countries, each classified as either core or periphery. Copula Asymmetric DCC-GARCH is estimated for each country-pair to measure the dynamic interest rate correlations for deposits and loans to households. We then examine the determinants by regressing quarterly correlations on macroeconomic and cross-border linkages, banking, and sociological variables. We also assess the impact of the two crises and of policy initiatives, including negative interest rate, Single Supervisory Mechanism, and Single Regulatory Mechanism. Different panel regressions reveal limited, although varied, influence of determinants on correlations across different products, maturities, and country groups. We conclude that the intrinsic features of the retail banking industry, such as customers' trust, information asymmetry, and political influence, hinder strong interest rate convergence in the euro area.

Time-Varying Bond Market Integration in EMU
( Priyanshi Gupta ),( Sanjay Sehgal ),( Florent Deisting ) 세종대학교 경제통합연구소(구 세종대학교 국제경제연구소) 2015 Journal of Economic Integration Vol.30 No.4
We examine the level and progress of bond market integration amongst the eleven Economic and Monetary Union countries with active bond markets, over normal and crisis periods. The study covers data from January 2002 up to March 2014. We employ seven indicators for assessing integration, namely beta convergence, sigma convergence, variance ratio, Asymmetric Dynamic Conditional Correlation, dynamic co-integration, market synchronisation, and common factors approach. The results suggest that there is no heterogeneity in the integration process of large-sized economies and medium-sized economies, thereby restricting portfolio diversification potential. Further, bond market integration in the Economic and Monetary Union deteriorated during the crisis period, especially during the European debt crisis, with the economies of Greece, Ireland, Italy, Portugal, and Spain being the worst affected. We observe that bond markets take a lead in information linkages vis-a-vis stock markets, and hence should get precedence in policy intervention relating to market integration, development, and crisis management.

Integration from Retail Banking to Non-Financial Corporations in EMU
( Sanjay Sehgal ),( Priyanshi Gupta ),( Florent Deisting ) 세종대학교 경제통합연구소 2016 Journal of Economic Integration Vol.31 No.3
This paper investigates the integration process within the European Economic and Monetary Union’s retail banking industry by analyzing deposit and lending rates to nonfinancial corporations. The investigation covers the 2003~2014 period, examining the normal period, the global crisis period, and the European debt crisis period. The paper classifies sampled countries into three groups on the basis of their Gross Domestic Product to investigate the relationship between economic size and degree of integration. We employ five different indicators to assess various dimensions of integration: beta convergence, sigma convergence, variance ratio, asymmetric dynamic conditional correlation, and dynamic co-integration. The results point toward a weak degree of integration, which was worsened by the twin crises. In addition, results indicate that more heterogeneity exists in the credit market than in the deposits market. Furthermore, short-term maturity products are observed to be more converged than longer-term maturity products. We also observe a positive relationship between economic size of sampled countries and the degree of retail banking integration.

Recent progress and growth in biosensors technology: A critical review
Utkarsh Chadha,Preetam Bhardwaj,Rushali Agarwal,Priyanshi Rawat,Rishika Agarwal,Ishi Gupta,Mahek Panjwani,Shambhavi Singh,Chirag Ahuja,Senthil Kumaran Selvaraj,Murali Banavoth,Prashant Sonar,Badrish B 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.109 No.-
Crucial exploitation of biosensors has attained dominant significance in the meadow of drug innovation,drug identification, bio-remedy, food protection principles, security, protection, and ecological examination. It has direct to the innovation of specific and authoritative diagnostic tools that employ biologicalsensing elements as biosensors. Glucometers employ oxygen or hydrogen peroxide electrochemicalrecognition utilizing immobilized glucose oxidase electrodes, showing biosensors’ invention. Currentadvances in biological methods and instrumentation relating to fluorescence tags to nano-materials haveincreased the responsive limit of biosensors. The use of aptamers or nucleotides, antibodies, peptidearrays, and molecule imprinted polymers offer tools to build up novel biosensors over the classicalmethod. Integrated methods offer an improved perception for a buildup of precise and responsive biosensorswith high regenerative potentials. Various biosensors ranging from nanomaterials polymers tomicrobes have more comprehensive potential applications. Combining multifaceted approaches to designbiosensors that comprise the prospective for different usage is reasonably significant. In light of this, thisreview provides an overview of different types of biosensors being used, ranging from electrochemicaland fluorescence tagged, nanomaterials, silica or quartz, and microbes for various biomedical and environmentalapplications with the future outlook of biosensor technology.
