Glutaraldehyde-pea protein grafted polysaccharide matrices for functioning as covalent immobilizers

open access: yesScientific Reports, 2023
Three polysaccharide matrices (κ-Carrageenan (Carr), gellan gum, and agar) were grafted via glutaraldehyde (GA) and pea protein (PP). The grafted matrices covalently immobilized β-d-galactosidase (β-GL).

Forecasting Renminbi Exchange Rate Volatility Using CARR-MIDAS Model

open access: yesComplexity, 2022
In this study, we propose to employ the conditional autoregressive range-mixed-data sampling (CARR-MIDAS) model to model and forecast the renminbi exchange rate volatility. The CARR-MIDAS model exploits intraday information from the intraday high and low
