Type structure of (H3N–R–NH3)2I3BiI6, which consists of sheets of organic entities together with triiodide anions separated by layers of BiI6 octahedra, is defined by triiodide, hexaiodobismuthate, and organic diammonium. The prototype structure of (H3N(CH2)2SS(CH2)2NH3)2I3BiI6 (1) can accommodate various changes according to the nature of the organic group, such as conformation, length or size...

We present a loss-coupled distributed feedback microlaser, monolithically grown on standard 300-mm Si wafer using nano-ridge engineering. The cavity is formed by integrating metallic grating top of the nano-ridge. This allows forming laser without etching III-V material, avoiding damaged interfaces and associated carrier loss. Simulations, supported experimental characterisation modal gain devi...

Let i1 ≥ i2 ≥ i3 ≥ 1 be integers. An L(i1, i2, i3)-labelling of a graph G = (V, E) is a mapping φ : V → {0, 1, 2, . . .} such that |φ(u)− φ(v)| ≥ it for any u, v ∈ V with d(u, v) = t, t = 1, 2, 3, where d(u, v) is the distance in G between u and v. The integer φ(v) is called the label assigned to v under φ, and the difference between the largest and the smallest labels is called the span of φ. ...

Neuronal expression of apolipoprotein (apo) E4 may contribute to the pathogenesis of Alzheimer's disease (AD). In studying how apoE expression is regulated in neurons, we identified a splicing variant of apoE mRNA with intron-3 retention (apoE-I3). ApoE-I3 mRNA was detected in neuronal cell lines and primary neurons, but not in astrocytic cell lines or primary astrocytes, from humans and mice b...

Vaccinia virus, the prototypic poxvirus, efficiently and faithfully replicates its ∼200-kb DNA genome within the cytoplasm of infected cells. This intracellular localization dictates that vaccinia virus encodes most, if not all, of its own DNA replication machinery. Included in the repertoire of viral replication proteins is the I3 protein, which binds to single-stranded DNA (ssDNA) with great ...

In this study, we present data that support the presence of two distinct calmodulin binding sites within the angiotensin II receptor (AT(1A)), at juxtamembrane regions of the N-terminus of the third intracellular loop (i3, amino acids 214-231) and carboxyl tail of the receptor (ct, 302-317). We used bioluminescence resonance energy transfer assays to document interactions of calmodulin with the...
