TL;DR: In this article, the most recent progress on the solvothermal syntheses and applications of metal nanocrystals are discussed, including temperature, reaction time, solvent effects, ligand effects, facet-specific capping agent effects, and reductant effects.

TL;DR: In this article, the physical and chemical characteristics of mixed recycled aggregates were investigated in order to find criterions of acceptance for recycling aggregates to be used in concrete, and the comparison between the properties offers the possibility of pre-selecting a great quantity of mixed aggregates, these being suitable for either structural and non-structural concrete.

TL;DR: A genetic programming algorithm and different data mining approaches are proposed for solving the problems of predicting student failure at school using real data about 670 high school students from Zacatecas, Mexico.
Abstract: Predicting student failure at school has become a difficult challenge due to both the high number of factors that can affect the low performance of students and the imbalanced nature of these types of datasets. In this paper, a genetic programming algorithm and different data mining approaches are proposed for solving these problems using real data about 670 high school students from Zacatecas, Mexico. Firstly, we select the best attributes in order to resolve the problem of high dimensionality. Then, rebalancing of data and cost sensitive classification have been applied in order to resolve the problem of classifying imbalanced data. We also propose to use a genetic programming model versus different white box techniques in order to obtain both more comprehensible and accuracy classification rules. The outcomes of each approach are shown and compared in order to select the best to improve classification accuracy, specifically with regard to which students might fail.

TL;DR: The pooled estimates show that smoking is inversely associated with the risk of PD, and the four prospective studies that were based on follow‐up of mortality of smokers had many limitations.
Abstract: We estimated the pooled risk of tobacco smoking for Parkinson's disease (PD). Inclusion criteria included systematic searches of MedLine, PsycLIT, Embase, Current Contents, previously published reviews, examination of cited reference sources, and personal contact and discussion with several investigators expert in the field. Published prospective studies on PD and cigarette smoking. When two or more studies were based on an identical study, the study that principally investigated the relationship or the study that was published last was used. Seven prospective studies were carried out between 1959 and 1997, of which six reported risk estimates. Four cohorts were based on standardised mortality rates, which were exclusively of male. Only one study included risk estimates for both males and females separately. The risk of ever smoker was 0.51 (95% confidence interval, 0.43 to 0.61). There was an obvious protective effect of current smoking in the pooled estimate (relative risk, 0.35; 95% CI, 0.26-0.47). Former smokers had lower risk compared with never smokers (relative risk, 0.66; 95% CI, 0.49-0.88). Although our pooled estimates show that smoking is inversely associated with the risk of PD, the four prospective studies that were based on follow-up of mortality of smokers had many limitations. Further studies evaluating the association between smoking and PD in women are strongly needed.
