A dot hybridization method is presented for rapidly determining the relative concentrations of nucleic acids in a mixture, as well as the extent of sequence homology between related RNA or DNA species.

In this paper we define new homotopy groups for topological spaces. These groups generalize the homotopy groups of Hurewicz. By the use of these groups and by improved methods we obtain new results about the ordinary homotopy groups, and also easier proofs of known results. Among other things, we can show that 76(S3) is non-trivial. 1. One of the principal problems of modern topology is to devi...

 In this paper by use of mathematical modeling of an observer [14,15] the notion of relative information functional for relative dynamical systemson compact metric spaces is presented. We extract the information function ofan ergodic dynamical system (X,T) from the relative information of T fromthe view point of observer χX, where X denotes the base space of the system.We also generalize the in...

Floer homology is a beautiful theory introduced in 1985 by Andreas Floer [8]. It combined new ideas about Morse theory, gauge theory, and Casson’s approach [1, 14] to homology 3-spheres and the representations of their fundamental groups into Lie groups such as SU(2) and SO(3). From its inception, it was related to the study of the anti-self-dual Yang-Mills equations on 4-manifolds, and is the ...
