Block Recombination Approach for Subquadratic Space Complexity Binary Field Multiplication Based on Toeplitz Matrix-Vector Product

open access: yesIEEE Transactions on Computers, 2012
International audienceIn this paper, we present a new method for parallel binary finite field multiplication which results in subquadratic space complexity.

Chiral Allenylcarbonyls – Underexploited Building Blocks for Complex Synthesis

Letters in Organic Chemistry, 2022
Abstract: Chiral allenylcarbonyls such as allenoates remain underutilized in complex synthesis despite recent advances in synthesis methods to prepare them non-racemically. The field is now ripe for the employment of this class of allenes as building blocks to facilitate the construction of complex small-molecule compounds, such as bridged bicycles.

A crossover for complex building blocks overlapping

Proceedings of the 8th annual conference on Genetic and evolutionary computation, 2006
We propose a crossover method to combine complexly overlapping building blocks (BBs). Although there have been several techniques to identify linkage sets of loci o form a BB [4, 6, 7, 10, 11], the way to to realize effective crossover from the linkage information from such techniques has not been studied enough.

Anisotropy of building blocks and their assembly into complex structures

Nature Materials, 2007
A revolution in novel nanoparticles and colloidal building blocks has been enabled by recent breakthroughs in particle synthesis. These new particles are poised to become the 'atoms' and 'molecules' of tomorrow's materials if they can be successfully assembled into useful structures.

Heterobinuclear Complexes as Building Blocks in Designing Extended Structures

Inorganic Chemistry, 2002
The heterobinuclear complex [CuPrL(NO(3))(3)] has been used as a building block for the construction of a two-dimensional coordination polymer with the formula [CuPrL(NO(3)(2)(IN)], 1 (L(2-) = the dianion of the compartmental Schiff-base ligand obtained from the 2:1 condensation of 3-methoxysalicylaldehyde with 1,3-propanediamine; IN(-) = the ...

Network Motifs: Simple Building Blocks of Complex Networks

Science, 2002
Complex networks are studied across many fields of science. To uncover their structural design principles, we defined “network motifs,” patterns of interconnections occurring in complex networks at numbers that are significantly higher than those in randomized networks.

Difluorobis(pentafluoroethyl)phosphoranide: A Promising Building Block for Phosphoranidometal Complexes

Inorganic Chemistry, 2021
Despite the fact that different metal tetrafluorophosphoranides, M[PF4] (M = Cs, Ag, K), decompose readily, we successfully enhanced the stability of such species by the replacement of two fluorine atoms with electron withdrawing pentafluoroethyl groups.

From Small Building Blocks to Complex Molecular Architecture

Organic Letters, 2006
[reaction: see text] We describe a synthesis of a dendrimer-like amphiphile containing a flat rigid core and 12 hydrophobic and hydrophilic arms. We employ a modular approach based on stepwise protection chemistry starting from simple building blocks.
