Geological Journal, EarlyView.Our petrochemical studies on ~1.2 Ga granitoids of the Natal Metamorphic Belt, South Africa, do not suggest any property similar to Phanerozoic‐style subduction‐related granitoids. Plot of Kotongweni Tonalite in Y versus Sr diagram (after Moyen 2011), note that most samples have Sr/Y < 50.

Efficient In-Database Maintenance of ARIMA Models
, 2011 Forecasting is an important analysis task and there is a need of integrating time series models and estimation methods in database systems. The main issue is the computationally expensive maintenance of model parameters when new data is inserted. In this paper, we examine how an important class of time series models, the AutoRegressive Integrated ...

Health Care Science, EarlyView.Using ARIMA‐based interrupted time‐series analysis, this study reveals that China's NVBP policy significantly reduced daily costs and enhanced affordability, driving generic substitution and the elimination of low‐quality products. Additionally, non‐winning manufacturers adopted strategic pricing behaviors to segment the market.

Long short-term memory networks for enhancing real-time flood forecasts: a case study for an underperforming hydrologic model [PDF]
Hydrology and Earth System SciencesFlood forecasting systems play a key role in mitigating socioeconomic damage caused by flood events. The majority of these systems rely on process-based hydrologic models (PBHMs), which are used to predict future runoff.
