Probing Dark Energy with Snap
The distance-redshift relation observed for supernovae has led to the discovery that the expansion of the universe is accelerating. A next generation experiment, the Supernova/Acceleration Probe (SNAP), can investigate the nature of the dark energy responsible, determining its energy density contribution and equation of state. In addition, indications of time variation in the equation of state ...
متن کاملHybrid Wireless-Wired Optical Sensor for Extreme Temperature Measurement in Next Generation Energy Efficient Gas Turbines
Accuracy, reliability, and long lifetimes are critical parameters for sensors measuring temperature in gas turbines of clean coal-fired power plants. Greener high efficiency next generation power plants need gas turbines operating at extremely high temperatures of 1500°C, where present thermocouple temperature probe technology fails to operate with reliable and accurate readings over long lifet...
متن کاملBaryon Oscillations as a Cosmological Probe
Mapping the expansion of the universe gives clues to the underlying physics causing the recently discovered acceleration of the expansion, and enables discrimination among cosmological models. We examine the utility of measuring the rate of expansion, H(z), at various epochs, both alone and in combination with distance measurements. Due to parameter degeneracies, it proves most useful as a comp...
متن کاملWeak Lensing from Space Iii: Cosmological Parameters
Weak gravitational lensing provides a unique method to directly map the dark matter in the universe and measure cosmological parameters. The current weak lensing surveys are limited by the atmospheric seeing from the ground and by the small field of view of existing space telescopes. These limitations can be circumvented using wide field observations from space, such as those afforded by the fu...
متن کاملدورگهسازی در محل؛ اصول و کاربردها : مقاله مروری
In situ hybridization (ISH) is a method that uses labeled complementary single strand DNA or RNA to localize specific DNA or RNA sequences in an intact cell or in a fixed tissue section. The main steps of ISH consist of: probe selection, tissue or sample preparation, pre-hybridization treatment, hybridization and washing, detection and control procedure. Probe selection is one of the important ...
