in the first chapter we study the necessary background of structure of commutators of operators and show what the commutator of two operators on a separable hilbert space looks like. in the second chapter we study basic property of jb and jb-algebras, jc and jc-algebras. the purpose of this chapter is to describe derivations of reversible jc-algebras in term of derivations of b (h) which are we...

following our previous presentation of a new three-fold symmetry for derivation of the magic numbers of nuclei based upon a quark state model of nuclei, here the nuclear binding energy is obtained from such new perspective. from this point of view, since each nucleon is made of three quarks, the binding energy of nuclei contains a volume term proportional to 3a (a is mass number). by considerin...

in this paper, we introduce the concept of dynamical distance on a nuclear con- guration space. we partition the nuclear con guration space into disjoint classes. this clas-si cation coincides with the classical partitioning of molecular systems via the concept ofconjugacy of dynamical systems. it gives a quantitative criterion to distinguish di erentmolecular structures.

although the genome is defined by its primary sequence, its functional properties, are determined by far more complex mechanisms and depend on multiple layers of nuclear organization. the architecture of the nucleus includes two overlapping structures: the chromatin and a framework structure named the nuclear matrix. ultra-structural studies reveal that the nuclear matrix is a network consistin...
