Near-field scanning optical microscopy of molecular aggregates: The role of light polarization.

We consider theoretically near-field absorption spectra of molecular aggregates stemming from a scattering scanning near-field optical microscopy type setup. Our focus is on the dependence on the direction and polarization of the incoming electromagnetic radiation, which induces a Hertz dipole with a specific orientation at the tip-apex. Within a simple description, which is based on the eigenstates of the aggregate, absorption spectra are calculated for the near field created by this dipole.

Fibrodysplasia Ossificans Progressiva in a Four year Old Child.

Introduction: Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disoder characterized by bone formation within muscles tendons and ligaments. It has an incidence of one in two million. We hereby report a case of FOP in a four year male child from a tribal family in orissa.
