This paper investigates the effects of the spot-futures spread on the return and risk structure in currency markets. Using a bivariate dynamic conditional correlation GARCH framework, we find evidence of asymmetric effects of positive and negative spreads on the return and the risk structure of...

This study examines whether the expiration-day effects of stock options traded in Australian Stock Exchange on return, volatility, trading volume, and temporary price changes of individual stocks vary with the availability and the settlement method of individual stock futures contracts. Using...

While the relationship between oil prices and stock markets is of great interest to economists, previous studies do not differentiate oil-exporting countries from oil-importing countries when they investigate the effects of oil price shocks on stock market returns. In this paper, we address this...

Seven new 2-(2-Phenethyl) chromone derivatives ( 1-7 ), including four 2-(2-Phenethyl) chromone s ( 1-4 ), one 6, 7, 8 trihydroxy-2-(2-Phenethyl) chromone ( 5 ), one acetylated 5, 6, 7, 8-tetrahydroxy-2-(2-Phenethyl) chromone ( 6 ), and one chlorine-containing 5, 6, 7,...

The strengthening effects of Cr on Cu-Cr alloy are severely limited due to the relatively low solid solubility of Cr (0.7 wt.%). Also, the mechanical performance deteriorates severely at high temperature due to the Cr precipitates coarsening rapidly or dissolving in Cu matrix again. Here, the...

A remnant fertilizer monitoring system utilizing three-dimensional (3D) reconstruction is proposed to detect the amount of remaining fertilizer in the applicator’s tank. Bench tests are carried out to compare the performance of four algorithms to estimate the remnant fertilizer amount:...

Urea oxidation reaction (UOR) has emerged as a competitive approach for many energy-related technologies due to the low overpotential and fast reaction dynamics. The main challenge lies in fabricating high-efficient catalysts with optimized electronic structure and understanding the intrinsic...

Increasing the operating voltage of Ni-rich cathode materials is a highly promising route to achieve lithium-ion batteries with a high energy density. However, the unstable electrode-electrolyte interface (EEI) caused by the decomposition of carbonate-based electrolytes at high voltage is a...

Choice of iron sources is crucial to the improved electrochemical performances of LiMnPO 4 with poor electronic and ionic conductivity. Here, LiMn 0.8 Fe 0.2 PO 4 /C composites were synthesized through a rheological phase-assisted solid-state method using MnO and LiH 2 PO 4 as raw materials....
