Nanostructured-based broadband perfect absorbers are of great interest in a wide range applications, including spectroscopy, energy harvesting, and thermal photonics, etc. Here, planar square meta-ring nickel (Ni) is presented, which has the potential to absorb large operational wavelength starting from 400 nm 3000 nm. The proposed device model comprises configuration three layers with top bott...

Archaeologists working on plantation sites have typically ignored the role that violence played in the lives of enslaved African-Americans. By drawing together examples from archaeological publications in which violence has been mentioned, the commentary illustrates not only both the types and scale of violence endured by African-Americans, but also how archaeologists have effectively sanitized...

Let k be a perfect field of positive characteristic and Z an effective Cartier divisor in the projective line over with complement U. In this note, we establish some results about formal deformation theory overconvergent isocrystals on U fixed “local monodromy” along Z. En route, show that Hochschild cochain complex governs deformations module arbitrary associative algebra. We also relate to de...

We consider the size of circuits that perfectly hash an arbitrary subset S⊂{0, 1} of cardinality 2 into {0, 1}. We observe that, in general, the size of such circuits is exponential in 2k−m, and provide a matching upper bound.

We give various reformulations of the Strong Perfect Graph Conjecture, based on a study of forced coloring procedures, uniquely colorable subgraphs and ! ? 1-cliques in minimal imperfect graphs.

The amount of at retrieval time is one of the when looking for such functioiis. evidence about the effectivensss reduce the memory requirements perfect hash function proposed
