Lymphocyte Depletion Rate as a Biomarker of Radiation Dose to Circulating Lymphocytes During Fractionated Partial-Body Radiation Therapy [PDF]
PURPOSE: Radiation causes exponential depletion of circulating lymphocyte populations; in turn, radiation-induced lymphopenia is associated with worse survival for many solid tumors, possibly owing to attenuated antitumor immune responses.

Modeling the radiation pattern of LEDs
Light-emitting diodes (LEDs) come in many varieties and with a wide range of radiation patterns. We propose a general, simple but accurate analytic representation for the radiation pattern of the light emitted from an LED. To accurately render both the angular intensity distribution and the irradiance spatial pattern, a simple phenomenological model ...

The Radiation Pattern on an Ultrasonic Focusing Radiator [PDF]
A focusing quartz radiator made in the form of a concave-convex lens of constant thickness (and being X-cut on the axis) should radiate spherical sound waves which focus at the center of curvature of the radiator surfaces. Because of wave diffraction, the focus should deviate from infinitely sharp in the same manner as is well known in the optical ...
