Shot noise places a practical limit on the spatial and temporal resolution of lidar photocount data. A 2-D signal-processing technique that utilizes spatial and temporal filtering to reduce shot noise and increase resolution is described. The techniq

Arrays of InP-based avalanche photodiodes operating at 1.06-μm wavelength in the Geiger mode have been fabricated in the 128x32 format. The arrays have been hermetically packaged with precision-aligned lenslet arrays, bump-bonded read-out integrated

Lidar observations of the mesospheric sodium layer often reveal wavelike features moving through the layer. It is often assumed that these features are a layer density response to gravity waves. Chiu and Ching (1978) described the approximate form of

Recently-delivered women who wish to avoid pregnancy should initiate contraception before ovulation. Since the return of ovulation is not predictable, regardless of the woman's lactation status and duration of postpartum amenorrhea, contraception sho

Animal studies have yielded conflicting results on the carcinogenicity of long-acting progestins. Since more than 1.5 million women worldwide are currently receiving injections of a contraceptive progestin, depot medroxyprogesterone acetate, this is

Prostacyclin emanating from the uterus is proposed as a major contributor to the reduced risk of coronary disease among women. The hypothesis is supported by (1) epidemiologic evidence that the risk of myocardial infarction increases markedly followi

To evaluate the recent decision of the Advisory Committee on Immunization Practice to increase the recommended age for initial measles vaccination from 12 to 15 months, we carried out a case control study of vaccine failure in a recent measles epidem
