This is a welcome addition to the well-known 'Synopsis' series. These, owing to the absence of illustrations, are not suitable as an introduction to the subject, but form an excellent means of revision before examinations. Not all ophthalmologists will agree with some of the advice given. For example, the treatment of photophthalmia electrica given is cold bathing, dark room, and astringent lot...

The dark channel prior (DCP) technique is an effective method to enhance hazy images. Dark channel is an image with the same size as the hazy image which represents the haze severity in different places of the image. The DCP method suffers from two problems: it is incapable for removing haze from smooth regions, causing blocking effects on these areas; it cannot properly reduce a haze with a no...

Propagation of incoherently soliton pairs in photorefractive crystals under steady-state conditions is studied. These soliton states can be generated when the two mutually incoherent optical beams with the same polarization and wavelength incident on the biased photorefractive crystal. Such soliton pairs can exist in bright-bright, dark-dark, gray-gray as well as in bright-dark types. In this p...

CdSe nanocrystals in solution and films can enter a metastable state in which the highly luminescent nanocrystals become dark. This change, which we attribute to a surface transformation, can be caused by heating or by changing the environment of the nanocrystals at room temperature. The metastable transformation is reversed upon illumination of above-band-gap light, at which point the nanocrys...

Such mawkish passages recur with numbing frequency through this record of eighteen months in the life of an American, white, middle class, midwest girl who is fifteen when the book begins. Her father is the unnamed Dean of an unnamed American University; they live in a lovely Spanish style house with walls of thick dark wood and two steps down into a sunken living room. One can imagine. Her mot...
