Birth and Early Development of Indian Astronomy [PDF]
IN Astronomy Across Cultures: The History of Non-Western
Astronomy, Helaine Selin (ed), Kluwer, 2000, pp. 303-340, 2001 This paper provides an overview of the birth and early development of Indian astronomy. Taking account of significant new findings from archaeology and literary analysis, it is shown that early mathematical astronomy arose in India in the second millennium BC.

Applications for New Scintillator Technologies in Gamma Ray Astronomy
, 2016 Scintillators have long been used for probing the high energy universe. The reliability and low cost of scintillator-PMT detectors have made them the de facto standard for experiments on high altitude balloons and in orbiting satellites.

The Known and Unknown About Female Reproductive Tract Mucus Rheological Properties
BioEssays, EarlyView.Mucus viscosity changes as spermatozoa travel through the female reproductive tract to the egg in humans, bovines, mice, and other mammals. These changes may aid in spermatozoa navigation. However, limited information is available on the viscoelastic properties of female reproductive tract mucus, and consistent measurement techniques are lacking ...
