In the conditions of changing climate, plants are continuously subject to several biotic and abiotic stresses. Among these stresses, drought is one of the most severe abiotic stress which threats crops production and yield. Crops demonstrate various morphological, physiological, biochemical and molecular responses under water stress. This review describes some aspects of drought induced changes in morphological, physiological, biochemical and molecular changes in plants. Drought triggers a wide variety of plant responses, ranging from cellular metabolism to changes in growth development including roots, shoots and final yield. Moreover, understanding the biochemical and molecular responses to drought is essential for perception of plant resistance mechanisms to water-limited conditions. The sections of this review deal with plant responses including root growth, transpiration, photosynthesis, phenotypical flexibility, accumulation of solutes and expression of some genes and proteins for improving the tolerance to the drought stress

A recommendation system is a program which attempts to predict items that users may be interested in, considering their preference and taste. Collaborative filtering is an algorithm which is most commonly used in the recommendation system. It recommends the items that users are interested in with similar preferences. The system finds similar users based on all users' purchase and rating data. However, user preferences can change, and this kind of change may slow down recommendation performances. To upgrade these recommendation performances, this study proposes a user preference-reflected recommendation technique. The precision and MAE of the proposed method were measured, using MovieLens data set. Compared to conventional collaborative filtering techniques, the proposed method revealed better results.

A recommender system sorts and recommends the information which meets personal preferences among a huge amount of data provided by e-commerce. In particular, collaborative filtering (CF) is the most widely used technique in these recommendation systems. This method finds neighboring users who have similar preferences with particular users and recommends the items preferred by the former. This study proposes a neural network learning model as a new technique to find neighboring users using the collaborative filtering method. This kind of neural network learning model takes care of a sparseness problem during the analysis stage among those related with target users. The proposed method was tested with MovieLens data sets, and the results showed that precision improved by 6.7%.
