The present paper compares the performance of two recurrent neural networks for rainfall-runoff modeling in the Zou River basin at Atchérigbé outlet. To this end, we used daily precipitation data over the period 1988-2010 as input of the models, such as the Long Short-Term Memory (LSTM) and Recurrent Gate Networks (GRU) to simulate river discharge in the study area. The investigated models give good results in calibration (R2 = 0.888, NSE = 0.886, and RMSE = 0.42 for LSTM;R2 = 0.9, NSE = 0.9 and RMSE = 0.397 for GRU) and in validation (R2 = 0.865, NSE = 0.851, and RMSE = 0.329 for LSTM;R2 = 0.9, NSE = 0.865 and RMSE = 0.301 for GRU). This good performance of LSTM and GRU models confirms the importance of models based on machine learning in modeling hydrological phenomena for better decision-making.展开更多

But pregnant women, especially in Africa, do not attend antenatal clinics as recommended by the WHO. The general objective of this study was to study the norm in terms of Antenatal Consultation (ANC) frequency as well as the determinants of the frequency among women who gave birth in the maternity hospitals of Agbangnizoun. Our research was a cross-sectional, descriptive, retrospective and quantitative type, which was carried out among 335 women in Agbangnizoun, Benin from 1 February to 3 April 2020 (3 months), in order to find out the general or specific characteristics of women that we associate with the frequency of prenatal consultation. At the end of the study, we found that 60%, 68% and 15% of the surveyed population had received ANC in the first, second and third trimesters, respectively. Ethnicity, income level of spouses over the three trimesters as well as the level of their knowledge and overall practice of ANC are determinants of the frequency of prenatal consultation.展开更多

To start his speech, Zou made an analysis of the state of China’s enterprise reform. The Chinese government has for many years been concerned with the reform of enterprises, that of state-owned enterprises in particular. Since the reform and opening began, it has, based on the national conditions, given the enterprises more sell-decision rights, put the Stateowned industrial Enterprise Law of展开更多
