Real‐Time Forecasting Using Mixed‐Frequency VARs With Time‐Varying Parameters

Journal of Forecasting, EarlyView.
ABSTRACT This paper provides a detailed assessment of the real‐time forecast accuracy of a wide range of vector autoregressive models that allow for both structural change and indicators sampled at different frequencies. We extend the literature by evaluating a mixed‐frequency time‐varying parameter vector autoregressive model with stochastic ...

Hierarchical Regularizers for Reverse Unrestricted Mixed Data Sampling Regressions

Journal of Forecasting, EarlyView.
Abstract Reverse Unrestricted MIxed DAta Sampling (RU‐MIDAS) regressions are used to model high‐frequency responses by means of low‐frequency variables. However, due to the periodic structure of RU‐MIDAS regressions, the dimensionality grows quickly if the frequency mismatch between the high‐ and low‐frequency variables is large.

Preparation and Characterization of Carbon Quantum Dots (CQD) and CuFe2O4–CQD Composite Materials for Photo and Electrochemical Applications

Global Challenges, EarlyView.
The incorporation of copper and iron metal ions in the carbon quantum dots, enhances their combined use as supercapacitors and biomarkers and optimizes their degradation efficiency. Abstract The Carbon quantum dots (CQD) is prepared from ascorbic acid, and the photophysical, structural, and metal sensing behavior of the CQD is investigated in detail ...

Production and Characterization of Open Cell Cordierite from Boron and Waste Materials by Geopolymer Method for the Emission After Treatment System of Diesel Engines

Global Challenges, EarlyView.
Open porous geopolymer‐based cordierite materials are produced due to the porous structure, temperature resistance, easy and low cost applications of geopolymer. For the composition of cordierite, waste boron clay, metakaolin, fly ash and magnesium carbonate are used, while keeping the geopolymerization temperature constant, sodium silicate, sodium ...
