Cigarette smoking is common despite adverse health effects. Nicotine's effects on learning may contribute to addiction by enhancing drug-context associations. Effects of nicotine on learning could be direct or could occur by altering systems that modulate cognition. Because thyroid signaling can alter cognition and nicotine/smoking may change thyroid function, nicotine could affect learning thr...

In order to improve the prediction accuracy of ionospheric total electron content (TEC), a combined intelligent model (MMAdapGA-BP-NN) based on multi-mutation, multi-cross adaptive genetic algorithm (MMAdapGA) and back propagation neural network (BP-NN) was proposed. The combines international reference ionosphere (IRI), statistical machine learning (SML), BP-NN, MMAdapGA. Compared with IRI, SM...

<p>E-learning systems installed in educational institutions have increased the efficiency of scholarly processes over years. E-learning, however, has faced many factors affecting continuous intention teachers and students to use e-learning, such as student satisfaction, productivity, academic success. Therefore improve success, there is a need for enhance their e-learning programs. Thus p...

This unprecedented study applies deep learning, which a branch learning techniques, and evaluate severity rail combined The defects in are settlement dipped joint. Features used axle box accelerations simulated using verified rolling stock dynamic behavior simulation called D-Track. A total...

BACKGROUND Analytic measurement of serum tumour markers is one of commonly used methods for cancer risk management in certain areas of the world (e.g. Taiwan). Recently, cancer screening based on multiple serum tumour markers has been frequently discussed. However, the risk-benefit outcomes appear to be unfavourable for patients because of the low sensitivity and specificity. In this study, can...

s English This study is based on the analysis of academic results of 692 undergraduate and graduate students in two disciplines in a French university who attended their courses using one out of four possible learning modalities. Within the two disciplines, Art History and Educational Sciences, students chose between face-to-face learning (on campus), paper-based distance learning (corresponden...
