Unit root and Engle-Granger cointegration
The unit root test was conducted on the price series and its first difference (return) series. The ADF test was applied to both the price and return series, with the lag length determined using the Schwarz…

The pontoon mesh rotary filter recirculation system was constructed in the Agricultural Hydraulic Engineering Laboratory of Xinjiang Agricultural University. This system consisted of a prefiltration pool, return…
This study utilized various datasets to analyze and simulate the vegetation dynamics in the YRB, the streamflow and sediment concentration of the YR, and the regulation of the Xiaolangdi Reservoir (Supplementary Table 2)….
In a proof-of-concept study, we selected extensively studied G2 electrolytes to serve as the typical mode for our analysis. To evaluate high-voltage stability, we employed a P3-phase Na2/3Ni1/2Mn1/2O2 (NNM) electrode material with a particulate…
Water once existed in abundance of at the surface of Mars. How much of that water has been stored in the planet’s crust is still unclear, according to a new analysis.
More than 3 billion years ago, Mars intermittently had liquid water on its…
At least two mass extinction events in Earth’s history were likely caused by the “devastating” effects of nearby supernova explosions, a new study suggests.
Researchers at Keele University say these super-powerful blasts — caused by the death of…
