Oil still contributes around 30 % to Russia's commodity export earnings, therefore the impact of oil prices on Ruble's exchange rate is current interest Russian economists. Instruments time series analysis were used test a proposition that ruble’s has become less dependent Brent crude price in recent years. We obtained 1,095 weekly observations for years 2000 2020 from FINAM company website. Ou...

Climate change is a major concern the world over more so for predominantly agrarian country like India. In this paper we analyze time horizon dynamics of crop and climate variables at regional level in We also co-movements yields with temperature rainfall to observe coherence across heterogenous horizons. employ Bai-Perron structural break Continuous wavelet transform methods on yearly data sev...

Macroeconomic stability is an objective emerging economy desired to achieve but oil price shocks and fluctuations in nominal exchange rates tend restrain the ability of these economies such macroeconomic balance. Regrettably, are prone have structural breaks defined periods. We therefore, implemented a bivariate diagonal BEKK model, Zivot-Andrews Bai-Perron breakpoint tests evaluate effect pres...

The molecular mechanism for cisplatin (CDDP)resistance of cancer cells has not yet been clarified, despite extensive studies. Here, we investigated whether deathassociated protein (DAP) kinase, an apoptosis modulator, was involved in CDDP-resistance by examining the ME180 human cervical squamous cancer cell line and 6 monoclonal ME180-derived CDDP-resistant subclones. Co-treatment with CDDP and...

Background: An estimated 25 % of the alcohol consumed in China is traditional unrecorded alcohol produced and distributed informally. Consequently there is concern about its safety and its contribution to public health risk. Little has been written about this type of alcohol in China. Methods: Researchers observed the manufacture of traditional bai jiu in a rural area of Hubei Province, Central...

The research focused on leaders in market, namely, China, USA, EU, Brazil Argentina. Several...

The concept of the Perron complement of a nonnegative and irreducible matrix was introduced by Meyer in 1989 and it was used to construct an algorithm for computing the stationary distribution vector for Markov chains. Here properties of the generalized Perron complement of an n×n irreducible Z-matrixK are considered. First the result that the generalized Perron complements of K are irreducible...
