Asymmetric relationship between price and volatility is a prominent feature of the financial market time series. This paper explores price-volatility nexus in cryptocurrency markets investigates presence asymmetric effect uptrend (bull) downtrend (bear) regimes. The conventional GARCH-class models have shown that markets, reactions to returns differ from those other traditional assets. We addre...

In recent years, the use of electroencephalography (EEG) has grown as a tool for diagnostic and brain function monitoring, being simple non-invasive method compared with other procedures like histological sampling. Typically, in order to extract functional responses from EEG signals, prolonged repeated stimuli are needed because artifacts generated recordings which adversely impact stimulus-res...

In this paper, we try to classify the emotional cues of sound and visual stimuli solely from their source characteristics, i.e., 1D time series generated audio signals two-dimensional matrix pixels affective picture stimulus. The sample data consists six 15 s each pictures, which three belonged positive negative valence, respectively. Detrended Fluctuation Analysis (DFA) has been used calculate...

Fires bring up the debate about their impact on Brazil’s economic growth. Some processing tools such as cointegration and, especially, correlation have been applied for identifying possible transmission or contagion mechanisms between distinct time series. This paper adopts detrended cross-correlation analysis (DCCA) and rolling window approach to investigate dynamic coupling fires evolution of...

Using the detrended cross-correlation analysis (DCCA) coefficient and the detrendedpartial cross-correlation analysis (DPCCA) coefficient, we investigate cross-correlations and net cross-correlations among five major world gold markets (London, New York, Shanghai, Tokyo, and Mumbai) at different time scales. We propose multiscale influence measures for examining the influence of individual mark...

The response of plant species composition, diversity and soil nutrient availability to different canopysizes and age gaps in a Pinus Massoniana plantation were surveyed in Taizishan, Hubei province, central China. The soil chemical properties of 27 gaps and 3 non-gaps were measured and compared. The study objectives were: (a) confirm whether and when nutrient pulses emerged in small gaps; (b) d...
