Long-run relationships and structural breaks have often been confused so that many investigators ignore the in long-run stock price relationships. In this paper, we investigate among prices BRICS countries a bivariate framework. We used non-linear threshold cointegration test, which endogenously incorporates possible regime shift behaviors into from 2004 to 2018. The Johansen Gregory Hansen Hat...

objective: in this paper, we have introduced topoisomerase inhibitors, mechanism of action and types of them. dna topoisomerases are ubiquitous enzymes that catalyze essential enzymes to solve the topological problems accompanying key nuclear processes such as dna replication, transcription, repair and chromatin assembly by introducing temporary single or double strand breaks in the dna. result...

This study estimates the effects of dual long memory property and structural breaks on persistence level six major cryptocurrency markets. We apply Bai Perron break test, Inclán Tiao’s iterated cumulative sum squares (ICSS) algorithm, fractionally integrated generalized autoregressive conditional heteroscedasticity (FIGARCH) model, with different distributions. The results show that characteriz...

The objective of the study was to analyze whether changes in money supply can account for variations inflation dynamics presence structural breaks by using data period 1970-2019. Zivot Andrews (one break) and Lee Strazicich (two breaks) unit root tests were used detect shocks. To determine long run relationship shocks, Gregory & Hansen (1996) Cointegration test used. Results show a robu...

purpose: to evaluate the underlying causes of rhegmatogenous retinal detachment (rrd) in eyes operated for this reasion. methods: out of 1473 patients who underwent retinal detachment surgery, records of 369 patients were randomly selected and evaluated for the types of retinal breaks, the underlying disorders, and location of breaks. results: fifty-two percents of patients were less than 50 ye...

Are structural breaks models true switching models or long memory processes? The answer to this question remain ambiguous. A lot of papers, in recent years, have dealt with this problem. For instance, Diebold and Inoue (2001) and Granger and Hyung (2004) show, under speci c conditions, that switching models and long memory processes can be easily confused. In this paper, using several generatin...

The mutant mouse lymphoma cell line (L5178YAII), resistant to X-rays, ultraviolet light and alkylating agents, was reinvestigated in an attempt to establish the nature of the mutation. These cells were compared with P388 mouse lymphoma cells, which exhibit normal sensitivity to these mutagens. A series of studies was conducted to compare DNA alkylation and strand breakage with cell survival aft...
