Testing of Fractional Cointegration in Macroeconomic Time Series [PDF]

We propose in this article a two-step testing procedure of fractional cointegration in macroeconomic time series. It is based on Robinson’s (1994) univariate tests and is similar in spirit to the one proposed by Engle and Granger (1987), testing ...

Covalent Organic Frameworks for Photocatalytic CO2 Reduction: Metal Integration Principles, Strategies and Functions

Advanced Functional Materials, EarlyView.
Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.

Diophantine Approximation Exponents and Continued Fractions for Algebraic Power Series

Journal of Number Theory, 1999
Soit \(\mathbb F\) un corps fini de caractéristique \(p\). Si \(\alpha= \sum^{+ \infty}_{k=-n} a_kT^k\) est une série de Laurent et si \(a_{-n}\neq 0\), on pose \(|\alpha |=p^n\). Si \(\beta\in \mathbb F((T^{-1}))\) est algébrique sur \(\mathbb F(T)\) de degré \(\geq 2\), on note \(E(\beta)= \limsup(-\log |\beta -P/Q|/ \log|Q|)\) (où \(P\) et \(Q\in ...

On the Laplace Residual Series Method and Its Application to Time-Fractional Fisher’s Equations

Fractal and Fractional
In this paper, we develop an analytical approximate solution for the nonlinear time-fractional Fisher’s equation using a right starting space function and a unique analytic-numeric technique referred to as the Laplace residual power series approach.
