Abstract: Methods and systems are described for a system for measuring aberrations in a wave front. In the improved system multiple closely-spaced, small-aperture laser beams traverse an aberrating flow that introduces deflections of small-aperture laser beams from which aberrated wavefronts can be constructed. These beams may then be focused on position sensing devices using focusing lenses. The position sensing devices may then detect the positions of these beams and a difference between the detected position and the unaberrated position of the beams detected. This information may then be used to determine information regarding the optical aberrations introduced by the flow that may be used, for example, in improving communications systems and/or laser weapon systems.

Abstract: The present invention provides an immunogenically active component comprising inactivated Sarcocystis neurona cells and/or inactivated Neospora hughesi cells; antigens derived therefrom; DNA derived therefrom; or a mixture; or in combination with other vaccine components thereof. Further provided are vaccine compositions useful for preventing or ameliorating equine protozoal myeloencephalitis infection and disease and a method for the cell culture propagation of protozoan parasites.

Abstract: An immunotherapeutic composition and prophylactic and/or therapeutic methods of treatment are provided for West Nile virus in animals, and particularly non-human animals, such as horses, wherein said first flavivirus is less virulent and/or pathogenic flavivirus than said second flavivirus The composition and method of treatment include a monoclonal antibody to Kunjin virus E protein, wherein the monoclonal antibody is capable of neutralizing West Nile virus in the non-human animal notwithstanding that West Nile virus is more virulent and/or pathogenic than Kunjin virus.

Abstract: A method, composition and kit for reducing or preventing immunogenic interference in a multi-valent vaccine utilizes a nucleic acid or DNA component along with other non-nucleic acid immunogenic components.
