ABSTRACT
The structure and energetics and the chemistry of graphene on SiO2 surface are studied from first-principles. It is found that the energetic preference for the graphene layer to bind on specific sites on the O-terminated surface differs substantially from that on the Si-terminated surface. Regardless of the location of binding sites on a particular surface, electrons transfer from the graphene layer to the dielectric surface and its quantity is higher for the O-terminated surface. In addition, the electron transfer strongly depends on the type of surface termination but is independent of the binding site.

    Abstract  Null alleles can occur with any PCR-based STR typing system. They generally are due to deletions within the target region or primer binding sites or by primer binding site mutations that destabilize hybridization of at least one of the primers flanking the target region. Although...

    Abundance of pseudo splice sites in introns can potentially give rise to innumerable pseudoexons, outnumbering the real ones. Nonetheless, these are efficiently ignored by the splicing machinery, a process yet to be understood completely. Although numerous 5′ splice site-like sequences...

    Expression of the T-cell receptor (TCR):CD3 complex is tightly regulated during T-cell development. The mechanism and physiological role of this regulation are unclear. Here, we show that the TCR:CD3 complex is constitutively ubiquitylated in immature double positive (DP) thymocytes, but not...

    Motivation: Most de novo motif identification methods optimize the motif model first and then separately test the statistical significance of the motif score. In the first stage, a motif abundance parameter needs to be specified or modeled. In the second stage, a Z-score or P-value is used as...
