Several studies have assessed the association between MTHFR C677T polymorphism and the risk of congenital heart defects (CHDs), while the results were inconsistent. METHODS AND FINDINGS Multiple electronic(More)

The existing work often assumes that the friends of a user can always contribute to the sufficient storage capacity to store all data. However, this assumption is not always true in today's online social networks (OSNs) due to the fact that(More)
—The processing of massive small files is a challenge in the design of distributed file systems. Currently, the combined-block-storage approach is prevalent. However, the approach employs traditional file systems like ExtFS and may cause inefficiency for random access to small files. This paper focuses on optimizing the performance of data servers in(More)
