Recommender systems with social regularization
This paper proposes a matrix factorization framework with social regularization, which can be easily extended to incorporate other contextual information, like social tags, etc, and demonstrates that the approaches outperform other state-of-the-art methods. Expand
Normalized Word Embedding and Orthogonal Transform for Bilingual Word Translation
A solution which normalizes the word vectors on a hypersphere and constrains the linear transform as an orthogonal transform and can offer better performance on a word similarity task and an English-toSpanish word translation task is proposed. Expand
Effect of nano-TiO2 on strength of naturally aged seeds and growth of spinach
It is shown that the physiological effects are related to the nanometer-size particles, but the mechanism by which nano-TiO2 improves the growth of spinach seeds still needs further study. Expand
Distributed nonnegative matrix factorization for web-scale dyadic data analysis on mapreduce
This paper shows that by carefully partitioning the data and arranging the computations to maximize data locality and parallelism, factorizing a tens of millions by hundreds of millions matrix with billions of nonzero cells can be accomplished within tens of hours. Expand
Neurotoxicological effects and the impairment of spatial recognition memory in mice caused by exposure to TiO2 nanoparticles.
Exposure to TiO(2) NPs could possibly impair the spatial recognition memory ability, and this deficit may be possibly attributed to the disturbance of the homeostasis of trace elements, enzymes and neurotransmitter systems in the mouse brain. Expand
Influence of nano-anatase TiO2 on the nitrogen metabolism of growing spinach
Nano-anatase TiO2 treatment could obviously increase the activities of nitrate reductase, glutamate dehydrogenase, glutamine synthase, and glutamic-pyruvic transaminase during the growing stage and promote spinach to absorb nitrate, accelerate, inorganic nitrogen to be translated into organic nitrogen, and enhance the fresh weight and dry weights.

Protective effects of polydatin on lipopolysaccharide-induced acute lung injury through TLR4-MyD88-NF-κB pathway.
It is indicated that PD played a protective role in LPS-induced ALI and BEAS-2B cells and supported further study of PD as potential candidate for acute lung injury. Expand
Understanding web browsing behaviors through Weibull analysis of dwell time
Dwell time on Web pages has been extensively used for various information retrieval tasks. However, some basic yet important questions have not been sufficiently addressed, eg, what distribution isExpand
Effect of nano-TiO2 on photochemical reaction of chloroplasts of spinach
It is suggested that photosynthesis promoted by nano-TiO2 might be related to activation of photochemical reaction of chloroplasts of spinach. Expand
The Improvement of Spinach Growth by Nano-anatase TiO2 Treatment Is Related to Nitrogen Photoreduction
It was confirmed that nano-anatase TiO2 on exposure to sunlight could chemisorb N2 directly or reduce N2 to NH3 in the spinach leaves, transforming into organic nitrogen and improving the growth of spinach. Expand
