A linear relationship exists between the mean volume of garnet porphyroblasts and the squared inverse of mean matrix grain diameter for six samples of garnetiferous mica quartzite with identical thermal histories and similar mineralogy and modes. Thi

We report the observation of a gain of approximately $\mathrm{exp}\left(11\right)$ at 41.8 nm in 8-times-ionized xenon. This extreme ultraviolet (XUV) laser is driven by a 10-Hz, 70-mJ circularly polarized femtosecond laser pulse. The laser is focuse

Most signals reaching the mammalian brain are noisy, weak, and degraded so that the corresponding data that are carried by the signals are themselves incomplete and overlapping, and, more likely that not, the product of convolution with nonlinear sou

The volume of bone erosions in the metacarpophalangeal joints is a radiological feature that can be used to track the progression of rheumatoid arthritis. We introduce a hybrid segmentation algorithm that combines region growing and level-set segment

A 0.5-TW, 120-fs Ti:sapphire laser, when focused to greater than ${10}^{18}$ W/${\mathrm{cm}}^{2}$ onto a solid target, creates a plasma which emits radiation that extends beyond 1 meV. The x-ray yield increases as the 3/2 power of the incident laser

We demonstrate a contrast improvement of nearly a factor of 5 in a phantom medical x-ray image, using time-gated detection. This improvement is accomplished by temporal discrimination against scattered x-ray flux and may permit a significant reductio

The spatial quality of the Ti:sapphire amplified laser pulses is improved with a spatially filtering regenerative amplifier. Because of the high peak power of the system, 5 TW, it is necessary to limit the atmospheric beam path after pulse compressio

We have observed lasing in Xe/sup 8+/ XUV ion lasers operating by collisional excitation that required solid density targets and pump laser pulse energies of several hundred joules, a 10 Hz, 800-nm laser pulse with an energy of -70 mJ and time durati
