Current gradient-corrected density-functional approximations for the exchange energies of atomic and molecular systems fail to reproduce the correct 1/r asymptotic behavior of the exchange-energy density. Here we report ...

Social exchange theory (SET) is one the most influential conceptual paradigms in organizational behavior. Despite its usefulness, theoretical ambiguities within SET remain. As a consequence, tests of the model, as well a...

El objetivo de este artículo es examinar la relación existente entre la volatilidad de la tasa de cambio y el volumen de exportaciones, usando datos brasileños. Después de establecer la existencia de cointegración e...

We study the relationship between exchange rate regimes and economic growth for a sample of 154 countries over the post-Bretton Woods period (1974-1999), using a new de facto classification of regimes based on the actual...

Generalized gradient approximations (GGA's) seek to improve upon the accuracy of the local-spin-density (LSD) approximation in electronic-structure calculations. Perdew and Wang have developed a GGA based on real-space c...

Despite the remarkable thermochemical accuracy of Kohn–Sham density-functional theories with gradient corrections for exchange-correlation [see, for example, A. D. Becke, J. Chem. Phys. 96, 2155 (1992)], we believe tha...

Popular modern generalized gradient approximations are biased toward the description of free-atom energies. Restoration of the first-principles gradient expansion for exchange over a wide range of density gradients elimi...

From a theory of Hohenberg and Kohn, approximation methods for treating an inhomogeneous system of interacting electrons are developed. These methods are exact for systems of slowly varying or high density. For the groun...

Abstract This study investigated the impact of spatial variability in soil Cation Exchange Capacity and key macronutrients on soybean (Glycine max (L.) Merril) population establishment and yield across two distinct field...

The aim of the paper is to determine the interdependency of both balance of payments and fiscal deficit in the context of liberalized systems of capital flows with mainly stabile and appreciated exchange rate and their i...

Water repellency related to organic matter (OM) of coatings along the earthworm burrows (EB) walls can facilitate preferential flow due to limiting the water exchange with the soil matrix. The objectives of this work wer...

This study examined how fiscal deficit, exchange rate, and inflation rate impacted the economic growth of the Nigerian economy from 1980 to 2019. The cointegration connection in the study was discovered using the autoreg...

Abstract The forming quality of metal bipolar plate (BPP) flow channels in proton exchange membrane fuel cells (PEMFCs) is a key factor affecting battery performance. A flow channel with straight sidewalls and a low thin...

The process which involves ionic exchange was applied with the use of a Mexican zeolitic mineral (Taxco-Guerrero) to remove Zn, Cd, and Ni from an aqueous solutions. Mineral zeolitic samples in their sodium form were put...

A cation exchange matrix with zwitterionic and multimodal properties was synthesized by a simple reaction sequence coupling sulfanilic acid to a chitosan based support. The novel chromatographic matrix was physico-chemic...

This paper analyses the relationship between major cryptocurrencies (Bitcoin, Ethereum, and Tether) and selected regional equity markets of America, Asia, and Europe, while controlling for global financial factors includ...

Building on the premise that macroeconomic variables – such as prices, agricultural income, and the real exchange rate – are associated with deforestation dynamics, this study investigates both the longrun relationsh...
