This paper reviews the evolution of China''s real effective exchange rate between 1980 and 2002, and uses a structural vector autoregression model to study the relative importance of different types of macroeconomic shocks for fluctuations in the real exchange rate. The structural decomposition...

In this paper, to investigate the synthetic effffect of PrEP (pre-exposure prophylaxis) and ART (antiretrovial therapy) on HIV transmission among MSM (men who have sex with men) in heterogenous environment, an realistic HIV epidemic model with spatial diffusion is established. Here, HIV...

Tyrosine-containing peptide nano-assemblies have received tremendous attention because of their potential applications in biomedicine and nanomaterial fields. However, a current outstanding challenge is to direct the equilibrium between oxidative polymerization of precursors and the non-covalent...

Transition metal selenides have emerged as promising anode materials for sodium ion batteries (SIBs) while the large-scale application remains a challenge due to the inferior rate performance and short cycling life. Herein, the “flower-like” porous carbon anchored by Zn-Mn binary selenides...

Purpose The purpose of this paper is to describe and evaluate the time-varying and coupling dynamic characteristics of a 3-DOF parallel tool head. Design/methodology/approach From the view of control, a new dynamic index of a 3-DOF parallel tool head is proposed based on the dynamic model in the...

Purpose The purpose of this study is to develop a modified parameter identification method and a novel measurement method to calibrate a 3 degrees-of-freedom (3-DOF) parallel tool head. This parallel tool head is a parallel mechanism module in a five-axes hybrid machine tool. The proposed...
