Grazing Incidence and Multilayer X-Ray Optical Systems.
We discuss details of the spectral fitting procedures and algorithms used in deriving line count rates for the calibration of AXAF (the Advanced X-ray Astrophysics Facility) during end-to-end testing in the winter and spring of 1996/1997. An approach

The design, performance, and calibration of the seven flow proportional counters (FPCs) used during AXAF ground calibration are described. Five of the FPCs served as beam normalization detectors (BNDs), and two were used in the telescope focal plane

The design, calibration, and performance of the high purity germanium (HPGe) solid state detectors (SSDs) used in the calibration of the Advanced X-ray Astrophysics Facility high resolution mirror assembly (HRMA) is discussed. The focal plane SSD was

We describe here the computer program for modeling the FPCs and SSDs used in the ground calibration, relative and absolute, of AXAF. The program is called as a subroutine by XSPEC. The design is hierarchical: at the lowest level are models for single

Gibbon ape leukemia virus (GALV) enters cells following interaction with a specific receptor protein. We have isolated human complementary DNAs (cDNAs) encoding a protein which, when expressed in normally uninfectable mouse NIH3T3 cells, confers on t
