Shape from specular flow.

An image of a specular (mirror-like) object is nothing but a distorted reflection of its environment. When the environment is unknown, reconstructing shape from such an image can be very difficult. This reconstruction task can be made tractable when, instead of a single image, one observes relative motion between the specular object and its environment, and therefore, a motion field-or specular flow-in the image plane.

The history of tumescent anesthesia, part II: Vishnevsky's anesthesia from Russian textbooks, 1930 to 1970.

Although "tumescent anesthesia" has been described as a new technique, historical references reveal that in reality it has been used for decades all over the world. In "The History of Tumescent Anesthesia, Part I: From American Surgical Textbooks of the 1920s and 1930s" (Aesthetic Surg J 1998;18:353-357), Dr. Welch reported on early references to tumescent anesthesia in works published in the United States.
