We give an example of a first order theory T with countable D(T ) which c...

A ] 1 9 A ug 1 99 9 Regular representations of vertex operator algebras , I

In a previous study [Li3], the physical super selection principle in vertex operator algebra theory seems to tell us that for a vertex operator algebra V , one should be able to obtain each irreducible V -module from the adjoint module V by changing certain things. To a certain extent, what we are expecting is an analogue of the orbital construction of representations for a Lie group [Ki]. This...

I-9: Embryo Assessment and Selection

Over the years it has been an important goal to optimize the treatment of subfertility in order to obtain a better pregnancy rate and baby-take-home rate, usually combined with the goal of decreasing the rate of multiplet pregnancies. This implies optimizing the development of embryos through improved in vitro culture methods. And it also implies optimizing the methods of selection of embryos f...
