The model allows for separate segments of innovators and imitators, each of which follows a Bass-type diffusion process. Interestingly “seeding” the market is optimal for a limited range of situations and these do not appear to include those where there is a downturn in...

Benign cysts are one of the most common mass-occupying lesions of the breast and are often investigated with triple diagnostic trial (clinical examination, radiology, and cytology). Malignant melanoma is one of medicine's imitators, and metastatic disease can mimic cysts. Thorough investigation of any breast mass is essential to clarify its nature.

Hypersonic endoatmospheric interceptors are presently under serious consideration for strategic and theater missile defenses. On board infrared seekers are planned for terminal guidance. It is desirable to perform seeker trade studies determining such things as expected S/N, tracking performance and optimum wavelength of operation. The dynamics of the interceptor/target trajectories combine wit...

Severe pre-eclampsia with hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome and many other obstetric and medical or surgical conditions produce similar clinical presentations and laboratory study results to pre-eclampsia. Pre-eclampsia is freque...
