New technique stores images more efficiently

Article Abstract:

Mathematicians and engineers are developing a revolutionary new way to compress and store data. The method, called wavelets, could provide improved sound and image transmission, and possibly accomplish data compressions not previously thought possible. Wavelet theory derives from the mathematics of harmonic analysis. Pioneering work on wavelet theory was done by a French geophysicist, Dr. Jean Morlet, and Morlet's work was later related to the mathematics of harmonic analysis by Dr. Yves Meyer, a mathematician at Paris Dauhine University. Meyer's work was applied in the area of image processing by Dr. Stephan Mallat, now at New York University. More recently, Dr. Ingrid Daubechies of AT&T Bell Laboratories has carried these researches further forward. Scientists say her work has made wavelet theory practical.

F.D.A. PANEL BACKS BREAST IMPLANTS MADE OF SILICONE

Article Abstract:

The FDA has given the go-ahead to Inamed Corp. to distribute breast implants for women seeking the devices. The company had agreed already to conduct education sessions for doctors and patients and to monitor the women who receive implants. The FDA still is concerned about implant safety and durability over a period of 10 years or more. Some implant critics believe that a moratorium for sale of the devices should continue while saline implants remain available. Women are unhappy with saline because it creates an unnatural hardness in the breast, and saline implants can deflate unexpectedly.

Japanese labs in U.S. luring America's computer experts

Article Abstract:

Japanese companies lure American computer scientists into research laboratories in the US. Japanese computer makers are now investing more time, effort and money into research, and they are doing it in the US. Reactions to this trend range from some who see it as benefiting science to others who see it as damaging on the US industry. US computer scientists will be lured by lucrative salaries. They will have an opportunity to work with the latest and most advanced technologies, and the ability to have ideas turn into products instead of scholarly papers is also an enticement.
