The fundamental question addressed in this paper is that of computing the parallel prefix operation. In particular, we study the problem of performing such an operation in an n-dimensional SIMD hypercube, Q_n, with up to n-1 node faults. In an SIMD hypercube, during a communication step, nodes can exchange information with their neighbors only across a(More)
Fries rearrangement of substituted phenyl benzoates 1a-j to substituted hydroxy benzophenones 2a-j was achieved in excellent yield. Further benzoylation of 2a-j to benzoyloxy benzophenones 4a-n, a benzophenone analogue was achieved in good yield. All the newly synthesized compounds were evaluated for their anti-inflammatory activity and were compared with(More)
A one-pot, three-component, microwave irradiated and conventional solution-phase synthesis of bioactive venlafaxine analogs such as 2,3-disubstituted-1,3-thiazolidin-4-ones 3a-j under mild conditions and their characterization are reported. The novel thiazolidin-4-ones, 3-(2-(1-hydroxycyclohexyl)-2-(4-methoxyphenyl)ethyl)-2-phenyl-thiazolidin-4-one 3a,(More)
Purified manganese peroxidase (MnP) from Phanerochaete chrysosporium oxidizes nonphenolic beta-1 diarylpropane lignin model compounds in the presence of Tween 80, and in three- to fourfold lower yield in its absence. In the presence of Tween 80, 1-(3',4'-diethoxyphenyl)-1-hydroxy-2-(4'-methoxyphenyl)propane (I) was oxidized to 3,4-diethoxybenzaldehyde (II),(More)
The d-ary De Bruijn graph G = (V, E) on 1 I/ 1 = d” vertices is a labeled directed graph, with vertex labels that are n-tuples over the alphabet {0, l,..., dl}, such that there is an edge from a vertex labeled (u, . . . a,) to a vertex labeled (b,,...b,)wheneverb,=a,_i foralliintherange 2giGn. The De Bruijn graph has extensively been used in various(More)
