Public transportation ridership levels have decreased since the end of World War II. Transit systems in small cities struggle to maintain ridership levels high enough to continue receiving local subsi...
Nano-Fe3O4 Encapsulated-Silica Particles Bearing Sulfonic Acid Groups as a Magnetically Separable Catalyst for Highly Efficient Knoevenagel Condensation and Michael Addition Reactions（图）
magnetic nanoparticle silica Knoevenagel condensation Michael addition cyclic diketone
2013/10/4
Sulfonic acid-functionalized silica-coated nano-Fe3O4 particles (Fe3O4@SiO2-SO3H) have been prepared as a novel heterogeneous acid using a facile process. The material was subsequently identified as a...
Polynomial-Time Isomorphism Test for Groups with No Abelian Normal Subgroups
Group Isomorphism Permutational Isomorphism Code Equivalence
2012/12/4
We consider the problem of testing isomorphism of groups of order n given by Cayley tables. The trivial nlog n bound on the time complexity for the general case has not been improved upon over the pas...
