Working together in groups may be beneficial if compared to isolated efforts. Yet this is true only if all group members contribute to the success. If not, group efforts may act detrimentally on the fitness of their members. Here we study the evolution of cooperation in public-goods games on scale-free networks that are subject to deletion of links connected to the highest-degree individuals, i...

Currently, safety analyses mostly rely on codes which solve both the neutronics and thermal-hydraulics with assembly-wise nodes resolution as multiphysics heterogeneous transport solvers are still too time memory expensive. The pin-by-pin homogenized can be seen a bridge between traditional nodal calculations. In this work, simplified solver Tortin has been coupled sub-channel code COBRA-TF. ve...

In this paper, we present a hybrid approach for performing token and sentence levels Dialect Identification in Arabic. Specifically we try to identify whether each token in a given sentence belongs to Modern Standard Arabic (MSA), Egyptian Dialectal Arabic (EDA) or some other class and whether the whole sentence is mostly EDA or MSA. The token level component relies on a Conditional Random Fiel...

background:estrogens play a substantial role in the proliferation, progression and treatment of breast cancer by binding with two estrogen receptors, alpha and beta (erα and erβ). resistance to endocrine therapy is a major problem in the treatment of breast cancers and, in some cases, may be related to loss of er gene expression. we have already showed that erα methylation occurs in high freque...
