An Efficient Numerical Method for the Solution of the Schrödinger Equation by Licheng Zhang, Theodore E. Simos

“…More specifically we will study (1) the development of the new method, (2) the determination of the local truncation error (LTE) of the new method, (3) the local truncation error analysis which will be based on test equation which is the radial time independent Schrödinger equation, (4) the stability and the interval of periodicity analysis of the new developed method which will be based on a scalar test equation with frequency different than the frequency of the scalar test equation used for the phase-lag analysis, and (5) the efficiency of the new obtained method based on its application to the coupled Schrödinger equations.…”

Phosphate and nitrogen fertilization interactions with different cover crops on the yield of main crops in a Brazilian Cerrado Ferralsol by Rafael de Souza Nunes, Maria da Conceição Santana Carvalho, Thamires Dutra Zancanaro de Oliveira, Luiz Eduardo Zancanaro de Oliveira, Ana Clara Barbosa de Souza, Rodrigo Moura Pereira

“…ABSTRACT Growing off-season cover crops effectively enhances ecological diversity and improves nutrient cycling in agricultural systems, particularly when nutrient losses and low use efficiency are prominent. This study aimed to assess the interaction between different off-season cover crops and varying nitrogen (N) and phosphorus (P) application rates on common beans, soybeans, and corn yields, as well as on soil organic matter (SOM) and available P content (Mehlich-1) in a Cerrado loamy soil. …”
