Abstract Dirac cones can foster extraordinary electronic effects, as exemplified by the case of graphene layers. Angle-resolved photoemission reveals that adsorption selenium (Se) vapor on bilayer creates a symmetric hybrid clone at zone center. A detailed analysis aided first-principles calculations shows adsorbed layer consists an ordered array Se 8 molecules. The uncovered cloning mechanism ...

Proper functioning of sensory systems requires the generation of appropriate numbers and proportions of neuronal subtypes that encode distinct information. Perception of color relies on signals from multiple cone photoreceptor types. In cone-dominated retinas, each cone expresses a single opsin type with peak sensitivity to UV, long (L) (red), medium (M) (green), or short (S) (blue) wavelengths...

we investigate buchbaum and eisenbud's construction of the second symmetric power $s_r(x)$ of a chain complex $x$ of modules over a commutative ring $r$. we state and prove a number of results from the folklore of the subject for which we know of no good direct references. we also provide several explicit computations and examples. we use this construction to prove the following ...

We study several connected problems of holomorphic function spaces on homogeneous Siegel domains. The main object our concerns weighted mixed norm Bergman domains type II. These include: sampling, atomic decomposition, duality, boundary values, boundedness the projectors. Our analysis include Hardy spaces, and suitable generalizations classical Bloch Dirichlet spaces. One novelties in this work...
