Fluorescein in Lepra Reaction

were first recorded in India, by the present writers in Rao and Ray (1932). Since then, other workers, notable among them being Muir and Chatterjee (1932 and 1933) and Chatterjee (1933), have-attempted to study the action of Mercurochrome as well as that of one of its constituents, viz, fluorescein, in leprosy. Ryrie (1934) has further continued to study the influence of fluorescein on ' lepra ...

The Origin of the Lepra

One of the most striking features of the anatomical changes which develop in leprosy is the occurrence in the lesion of great numbers of large phagocytic cells filled with bacilli. These cells were first noted by Virchow, I and were given the name of "lepta cells" by him. Later investigation has shown that they are characteristic of the disease, the leprous nodule being composed almost entirely...

Building a Potassium MOT

A magneto-optical trap (MOT) was developed in order to cool and trap potassium atoms. This required construction of a mechanism for tuning and locking the frequency of a trap and repump laser in order to maintain the correct energy transitions needed to ensure trapping of the atoms. Once the lasers’ frequencies were locked, the beams were combined and amplified and can now be combined with lase...

SOT for MOT

In this paper we present a robust tracker to solve the multiple object tracking (MOT) problem, under the framework of tracking-by-detection. As the first contribution, we innovatively combine single object tracking (SOT) algorithms with multiple object tracking algorithms, and our results show that SOT is a general way to strongly reduce the number of false negatives, regardless of the quality ...
