Abstrae--The normal-mode-expansion technique is used to obtain a semi-analytical solution for the angular distribution of radiation at any optical distance within a linearly anisotropicscattering, absorbing, emitting, non-isothermal, gray medium between two parallel reflecting boundaries. Both conservative and nonconservative cases are considered. The general problem is decomposed into simpler ...

BRCA mutation carriers are recommended to start mammographic screening for breast cancer as early as age 25-30 years. We used an excess relative risk model (based on a pooled analysis of three cohorts with 7600 subjects who received radiation exposure) to estimate the lifetime risk of radiation-induced breast cancer from five annual mammographic screenings in young (<40 years) BRCA mutation car...

[1] This paper analyzes the sensitivity of simulated climate and energy balance to changes in soil emissivity over Northern Africa and the Arabian Peninsula and considers how this information may be used to improve emissivity parameterizations in climate models. Analysis of satellite observations suggests that the soil emissivity in current models is too high over this region. Sensitivity tests...

The mean and annual cycle of energy flowing into the climate system and its storage, release, and transport in the atmosphere, ocean, and land surface are estimated with recent observations. An emphasis is placed on establishing internally consistent quantitative estimates with discussion and assessment of uncertainty. At the top of the atmosphere (TOA), adjusted radiances from the Earth Radiat...
