Normal anatomy of the inner ear.

The three parts of the inner ear have been reviewed: the membranous (endolymph containing) labyrinth surrounded by the osseous (perilymph containing) labyrinth, and the otic capsule of bone that encases the osseous labyrinth. This is a brief survey of the normal anatomy, but one must always remember that the hallmark of the temporal bone is variation.

New Integral Representations for Solutions of Cauchy's Problem for Abstract Parabolic Equations.

A study has been made of Cauchy's problem for a class of abstract parabolic differential equations. Our study is based upon a transformation that maps solutions of second-order abstract Cauchy problems into solutions of first-order. This is a preliminary report on some of the results obtained. These results include (1) new representations for solutions of abstract parabolic equations, (2) applications to the heat equation, (3) a discussion of solution representations for second-order abstract Cauchy problems, and (4) applications to nonwell posed (in the sense of Hadamard) Cauchy problems.

A singular abstract cauchy problem.

In this note a singular abstract Cauchy problem is considered. A solution is obtained for this problem in terms of a regular abstract Cauchy problem. As an application we obtain a new solution of the initial value problem for a class of singular partial differential equations.
